  1. Fatigue in Patients with Lupus is Real Fatigue in patients with systemic lupus erythematosus (SLE) has been linked to anti-NR2 antibodies, which responds to treatment with belimumab, a study shows. (©ArtemidaPsy,Shutterstock.com) Whitney J. Palmer June 24, 2019 Lupus, Rheumatology, Women's Health Patients with systemic lupus erythematosus (SLE) who have higher levels of antibodies to the receptor in the brain associated with memory and learning also experience more severe levels of fatigue, new research shows. The results, published in a recent issue of Annals of Rheumat ic Diseases, identifies a link between fatigue—one of the most challenging symptoms patients with systemic lupus erythematosus face—and the presence of anti-NR2, a brain-reacting antibody. “The presence of anti-NR2 antibodies in patients with lupus with fatigue is a helpful diagnostic tool and may offer a major approach in the therapeutic management of this important disabling symptom in patients with lupus,” said Andreas Schwarting, M.D., a rheumatologist, immunologist, and medical director at the University Medical Center of the Johannesburg-Gutenberg University Mainz in Germany. Elevated levels of anti-NR2 have been reported in 25 percent to 38 percent of patients with lupus, they said, so these findings could affect a substantial number of patients. To determine the impact of these autoantibodies, researchers analyzed blood samples from 426 patients with lupus. They also assessed fatigue severity using a self-reporting questionnaire. The findings found that patients with higher anti-NR2 levels experienced the more significant impacts of fatigue, including motoric and cognitive fatigue. Researchers found no correlation between anti-NR2 levels and renal function, erythrocyte sedimentation rate, or C-reactive protein. Study results also showed belimumab effectively relieved fatigue. Patients receiving belimumab for six months to 36 months saw a significant decline in their levels of anti-NR2 antibodies, as well as a clinically significant drop in their fatigue scores. Overall, investigators said, the findings could directly impact patient care. “The results of our study offer a sustained clinical advantage: to add an objective measurement of fatigue in lupus patients to a subjective questionnaire,” they said. “Anti-NMDAR antibodies should be identified routinely for patients with lupus suffering from fatigue.” REFERENCE Schwarting A, Mockel T, Lutgendorf F, et al.

  2. Fracture Risk is High in Lupus Patients with systemic lupus erythematosus (SLE) are at an increased risk for fractures, new research shows. The risk is particularly high among patients with lupus nephritis. (©PollapatChirawongShutterstock.com) Whitney J. Palmer June 24, 2019 Lupus, Joint/Bone Health, News, Rheumatology Patients with systemic lupus erythematosus (SLE) are at an increased risk for fractures, new research shows. The risk is particularly high among patients with lupus nephritis. In a study published in a recent issue of Arthritis & Rheumatology, investigators foiund that patients with lupus nephritis were far more likely to break a bone than patients who do not have lupus. “Patients with lupus nephritis may be at particularly high risk of fracture due to secondary or tertiary hyperparathyroidism and vitamin D deficiency,” said study author Sara Tedeschi, M.D., MPH, a rheumatology fellow at Brigham and Women’s Hospital. To assess fracture risk, researchers examined medical records for 47,709 lupus patients, including 9,449 patients who also had lupus nephritis. They identified pelvic, wrist, hip, and humeral fractures and compared these records to those of 190,836 patients without lupus. According to results, all lupus patients had a two-fold higher risk for any fracture compared to patients without lupus. Lupus nephritis patients have a three-fold risk over non-lupus patients and a 1.6-fold increase over lupus patients. However, findings did indicate that African American patients with lupus experienced a lower fracture risk than other study participants. When examining risk for specific types of fractures, investigators found lupus patients were at high risk for hip and pelvic fracture compared to patients without lupus. The risk was also elevated, though not as much, for humerus and wrist fractures. Researchers also discovered younger lupus patients had a 2.3-times higher fracture risk than younger patients who didn’t have lupus. Lupus patients over age 50 had a two-fold fracture risk increase. Less than half of patients with lupus received glucocorticoid treatment, indicating use of this medication was only responsible for some increased fracture risk. Ultimately, investigators said, these results reinforce the importance of identifying high-risk patients who have lupus and lupus nephritis to monitor them and provide for fracture prevention.

  3. Treatment with Tofacitinib Helps Relieve Arthritis and Rash Symptoms in Lupus Patients, Study Shows lupusnewstoday.com/2019/05/31/tofacitinib-relieve-arthritis-skin-rash-symptoms-sle/ Ana PenaMay 31, 2019 Tofacitinib tablets, a medicine approved to treat rheumatoid and psoriatic arthritis, may work for lessening signs and symptoms of arthritis and skin rash in people with systemic lupus erythematosus (SLE), a small study has found. These findings were reported in the letter “Successful treatment of arthritis and rash with tofacitinib in systemic lupus erythematosus: the experience from a single centre” that was published in the journal Annals of Rheumatic Diseases. Tofacitinib is marketed by Pfizer with the brand name Xeljanz for treating rheumatoid and psoriatic arthritis in adults who have failed treatment with methotrexate or other disease-modifying anti-rheumatic drugs (DMARDs). The medicine also has been approved to help manage inflammation in adults with ulcerative colitis, another chronic inflammatory condition. It blocks the activity of certain janus kinases (JAK) enzymes, which are critical for the activity of the immune system. By targeting JAKs, tofacitinib inhibits the activity of several signaling molecules, including interferons and interleukins known to have a role in SLE development and progression. Clinical data collected from rheumatoid arthritis patients indicates that tofacitinib can act quickly to reduce inflammation, as corticosteroids do, but without the side effects of steroids. Tofacitinib has been used off-label to treat SLE in some patients, but there is still very little data about the effectiveness and safety of this treatment for lupus. That’s why a group of researchers at the Peking Union Medical College Hospital in China evaluated tofacitinib’s effectiveness in a group of 10 lupus patients seen at the center. Nine women and one man received 5 mg of tofacitinib two times a day, and were followed by the team for at least four weeks and up to one year. At each follow-up visit, patients were monitored for disease activity with laboratory tests, such as measurement of anti-dsDNA antibodies and complement C3 levels, and by using scoring systems commonly used in clinics — SLE Disease Activity Index-2000 (SLEDAI-2K) and physician’s global assessment (PGA). Within one year, tofacitinib yielded a quick resolution of arthritis in all four patients who had such symptoms, and promoted significant relief in skin rash in six of nine participants. All those patients who experienced improvements achieved clinical remission of arthritis or skin rash. Tofacitinib’s effectiveness for rash, however, was more uncertain. In two patients, the medicine improved symptoms only partially or not at all. And another patient even experienced a flare during the follow-up period. Despite the rapid benefit seen for disease activity, SLE blood markers remained unchanged during the study. This agrees with prior tests reported for a different JAK inhibitor, baricitinib (sold in the U.S as Olumiant), in lupus patients and animal models. Two patients experienced treatment-related adverse events. One had herpes varicella zoster (shingles) and the other had alopecia (spot baldness). Both continued on tofacitinib, but their dosage was tapered and they ended up achieving disease remission. Based on these findings the team believes that “tofacitinib can rapidly improve the symptoms and signs of arthritis and partially improve skin rash in patients with SLE, sparing steroid to reach [clinical remission].” In view of the small number of patients studied and the variable periods of follow-up for each of them, researchers stress that more studies are needed to confirm tofacitinib’s effectiveness and define its specific indication in patients with SLE.
  4. Gene Changes Key to Successful Pregnancy in Lupus April 29, 2019 Pregnant women with lupus are more likely to suffer complications than those who don’t. Lupus Research Alliance Scientific Advisory Board members Dr. Virginia Pascual, Professor at Weill Cornell Medicine; and Dr. Jane Salmon, Collette Kean Research Professor at Hospital for Special Surgery, and their colleagues asked if testing the blood, of pregnant women with lupus, using advanced technologies could identify, early in pregnancy, lupus patients at high risk for complications. Their new paper in the Journal of Experimental Medicine shows that during uncomplicated pregnancy in both healthy and lupus women some genes that incite the immune system become less active. These changes may make the immune system less aggressive and reduce the odds that it will attack the fetus. However, women with lupus who had pregnancy complications, including preeclampsia, did not show the desirable decrease in these immune signatures. Doctors came up with the term “lupus” because they thought the disease’s skin inflammation looked liked a wolf’s bite. The study “supports the idea that in some cases, pregnancy can ‘tame the wolf.’” Drs. Timothy Niewold and Shilpi Mehta-Lee wrote in a commentary on the paper. They note that the findings may enable doctors to identify patients with lupus who are susceptible to pregnancy complications and need careful monitoring To the immune system, a fetus developing in the womb resembles a foreign invader. Normally during pregnancy, the mother’s immune system develops what researchers call tolerance and avoids attacking the fetus. But when patients with lupus become pregnant, their immune system may be less likely to develop tolerance to the fetus, leading to complications such as preeclampsia, premature birth, and even death of the fetus. In the new study, Dr. Pascual and colleagues compared 92 pregnant women with lupus to 43 pregnant women who didn’t have the disease. The researchers obtained blood samples from the women during and shortly after their pregnancies. To detect the earliest changes associated with pregnancy onset, the scientists also analyzed blood from patients undergoing assisted reproductive technology. The researchers evaluated the patients’ immune system by measuring the activity of different genes that help determine how strongly it responds to potential threats. For a subset of these study participants, the investigators also examined the types of cells that are producing the specific immune responses. Early in pregnancy, the activity of key genes decreased in women who didn’t have lupus, probably increasing their tolerance to the developing baby. The researchers saw similar changes in women with lupus who had successful pregnancies. However, the immune system of women with lupus who went on to develop complications was not turned down. Their immune system might be more likely to attack the fetus or prevent its proper development. This inability to turn down the immune activity appears to be a risk factor for adverse pregnancy outcomes in lupus. Testing for these changes in gene activity might pinpoint patients with lupus who are more likely to develop pregnancy complications and who needs careful monitoring and specific therapeutic intervention to improve the outcome. https://www.lupusresearch.org/gene-changes-key-to-successful-pregnancy-in-lupus/
  5. Discovery may help explain why women get autoimmune diseases far more often than men April 19, 2019 , University of Michigan Stark differences in the presence of autoimmune antibodies and immune factors in the blood (top) and kidneys (bottom) of mice that produced excess VGLL3 (left column) compared with healthy mice (right column). Credit: University of Michigan It's one of the great mysteries of medicine, and one that affects the lives of millions of people: Why do women's immune systems gang up on them far more than men's do, causing nine times more women to develop autoimmune diseases such as lupus? Part of the answer, it turns out, may lie in the skin. New evidence points to a key role for a molecular switch called VGLL3. Three years ago, a team of University of Michigan researchers showed that women have more VGLL3 in their skin cells than men. Now, working in mice, they've discovered that having too much VGLL3 in skin cells pushes the immune system into overdrive, leading to a "self-attacking" autoimmune response. Surprisingly, this response extends beyond the skin, attacking internal organs too. Writing in JCI Insight, the team describes how VGLL3 appears to set off a series of events in skin that trigger the immune system to come running—even when there's nothing to defend against. "VGLL3 appears to regulate immune response genes that have been implicated as important to autoimmune diseases that are more common in women, but that don't appear to be regulated by sex hormones," says Johann Gudjonsson, M.D., Ph.D., who led the research team and is a professor of dermatology at the U-M Medical School. "Now, we have shown that over-expression of VGLL3 in the skin of transgenic mice is by itself sufficient to drive a phenotype that has striking similarities to systemic lupus erythematosus, including skin rash, and kidney injury." Effects of excess VGLL3 Gudjonsson worked with co-first authors Allison Billi, M.D., Ph.D., and Mehrnaz Gharaee-Kermani, Ph.D., and colleagues from several U-M departments, to trace VGLL3's effects. They found that extra VGLL3 in skin cells changed expression levels of a number of genes important to the immune system. Expression of many of the same genes is altered in autoimmune diseases like lupus. The gene expression changes caused by excess VGLL3 wreaked havoc in the mice. Their skin becomes scaly and raw. Immune cells abound, filling the skin and lymph nodes. The mice also produce antibodies against their own tissues, including the same antibodies that can destroy the kidneys of lupus patients. The researchers don't yet know what causes female skin cells to have more VGLL3 to begin with. It may be that over evolutionary time females have developed stronger immune systems to fight off infections—but at the cost of increased risk for autoimmune disease if the body mistakes itself for an invader. The researchers also don't know what triggers might set off extra VGLL3 activity. But they do know that in men with lupus, the same VGLL3 pathway seen in women with lupus is activated. Many of the current therapies for lupus, like steroids, come with unwanted side effects, from increased infection risk to cancer. Finding the key factors downstream of VGLL3 may identify targets for new, and potentially safer, therapies that could benefit patients of both sexes. Lupus, which affects 1.5 million Americans, can cause debilitating symptoms, and current broad-based treatment with steroids can make patients far more vulnerable to infections and cancer. Patients' role in future research Their colleague and senior coauthor Michelle Kahlenberg, M.D., of the U-M Division of Rheumatology, is now recruiting patients with lupus for a study sponsored by U-M's A. Alfred Taubman Medical Research Institute that could provide answers to these questions and more. Billi, a resident in dermatology, notes that when she speaks with patients who come to Michigan Medicine's dermatology clinics for treatment of the skin problems lupus can cause, she has to acknowledge the limits of current treatment. Even so, she says, patients are eager to take part in studies by contributing skin and DNA samples that could lead to new discoveries about their condition. "Many patients are frustrated that they've had to try multiple therapies, and still nothing is working well," she says. "To be able to tell them that we're working on a mouse that has the same disease as them, and that we need their help, brings out their motivation and interest in research. They know that it's a long game, and they're in for it." More information: Allison C. Billi et al, The female-biased factor VGLL3 drives cutaneous and systemic autoimmunity, JCI Insight (2019).

Gudjonsson1,3 First published April 18, 2019 - More info Abstract Autoimmune disease is 4 times more common in women than men. This bias is largely unexplained. Female skin is “autoimmunity prone,” showing upregulation of many proinflammatory genes, even in healthy women. We previously identified VGLL3 as a putative transcription cofactor enriched in female skin. Here, we demonstrate that skin-directed overexpression of murine VGLL3 causes a severe lupus-like rash and systemic autoimmune disease that involves B cell expansion, autoantibody production, immune complex deposition, and end-organ damage. Excess epidermal VGLL3 drives a proinflammatory gene expression program that overlaps with both female skin and cutaneous lupus. This includes increased B cell–activating factor (BAFF), the only current biologic target in systemic lupus erythematosus (SLE); IFN-κ, a key inflammatory mediator in cutaneous lupus; and CXCL13, a biomarker of early-onset SLE and renal involvement. Our results demonstrate that skin-targeted overexpression of the female-biased factor VGLL3 is sufficient to drive cutaneous and systemic autoimmune disease that is strikingly similar to SLE. This work strongly implicates VGLL3 as a pivotal orchestrator of sex-biased autoimmunity. Introduction Autoimmune disease is common, can be deadly, and affects women disproportionately. The prevalence of systemic lupus erythematosus (SLE) is 9 times higher among women than men, and many other autoimmune diseases show similar profound female skewing (1). However, the cause of this female bias remains elusive. Previous work has focused primarily on the influence of sex hormones, yet female bias in autoimmunity is observed even prior to puberty and following menopause (2), indicating alternative mechanisms at play. As most autoimmune diseases remain incurable, investigating the causes of autoimmunity is critical, and the drivers of female-biased autoimmunity are logical targets. We previously identified the conserved putative transcription cofactor vestigial like family member 3 (VGLL3) as a candidate female-biased immune regulator (3). VGLL3 is more abundant in the epidermis of women than men and shows female-specific nuclear localization, suggesting a role in sex-biased transcriptional regulation. In cell culture, VGLL3 knockdown decreased expression of select female-biased immune transcripts, including B cell–activating factor (BAFF, also known as TNFSF13B), the target of the only currently approved biologic therapy for SLE. Intriguingly, men who have SLE showed loss of sex-specific regulation of VGLL3, demonstrating upregulation and nuclear localization of VGLL3 in inflamed skin (3). This suggested that VGLL3 may govern a key upstream regulatory program promoting autoimmunity, but this hypothesis had yet to be explored. Results Human and murine VGLL3 share 87% sequence homology, including an identical putative transcription cofactor domain (Supplemental Figure 1A; supplemental material available online with this article; https://doi.org/10.1172/jci.insight.127291DS1). Similar to human women, female mice showed 2.8-fold higher Vgll3 expression than male mice in the skin (P = 0.053) (Supplemental Figure 1B), suggesting conserved sex-biased dynamics. To test for a causative role for cutaneous VGLL3 in promoting autoimmune disease, we generated transgenic mice overexpressing Vgll3 under the control of the bovine keratin 5 (K5) promoter (Figure 1A), which drives gene expression primarily in the epidermis but also in some other stratified squamous epithelia (4). Levels of Vgll3, as shown by quantitative reverse transcription PCR (qRT-PCR), in transgenic skin varied both across and within founder lines, with transgenic mice generally showing 5- to 50-fold expression relative to WT mice, and no consistent variation by sex (data not shown). Compared with WT mice, these K5-Vgll3–transgenic mice showed increased epidermal VGLL3 staining, with conspicuous nuclear localization (Figure 1B) analogous to human VGLL3 distribution in affected skin of patients with SLE (3). Transgenic pups were indistinguishable from WT pups at birth. Within 6–12 weeks of life, they began developing progressive skin thickening and scaling prominently involving the face and ears, common sites for human discoid lupus erythematosus (DLE) lesions (Figure 1C and Supplemental Figure 1C). No consistent skin phenotypic variation by sex was noted among transgenic littermates (data not shown). Figure 1 Overexpression of VGLL3 in the epidermis produces a skin phenotype with gross and histologic features of cutaneous lupus. (A) Transgenic (TG) cassette.

In E–G, images are representative of sections from 3 WT and 3 TG animals examined. Histologically, early skin lesions showed epidermal thickening and focal interface dermatitis, an inflammatory reaction pattern seen in cutaneous lupus (Figure 1D and Supplemental Figure 1, D and E). TUNEL staining confirmed increased keratinocyte apoptosis (Figure 1E), subtle basement membrane thickening was evident on periodic acid–Schiff (PAS) staining (Figure 1F), and direct immunofluorescence (IF) revealed IgG and C3 deposition at the dermal-epidermal junction (Figure 1G all are characteristic features of cutaneous lupus in humans. To examine the effects of VGLL3 that were driving this lupus-like cutaneous phenotype, we evaluated WT mice and robustly expressing transgenic mice by qRT-PCR for transcript levels of a panel of proinflammatory and lupus-related factors. Many of these transcripts showed significant elevation in transgenic mice (Figure 2A and Supplemental Figure 2A), including Tnfsf13b (encoding BAFF); IFN-κ (Ifnk), the predominant type I IFN in cutaneous lupus (5); and Cxcl13, a biomarker of early-onset SLE, heightened disease activity, and renal involvement (6). IF studies of key VGLL3-regulated factors (Figure 2B) corroborated our qRT-PCR findings. Thus, epidermal VGLL3 overexpression drives immunological gene dysregulation, similar to what we previously observed in the skin of healthy women (3). Figure 2 Overexpression of VGLL3 in the epidermis recapitulates the autoimmunity-prone genetic signature of human female skin.

See Methods for additional statistical details. For a broader examination of VGLL3 effects, we performed RNA-seq of normal-appearing dorsal skin from WT and transgenic mice to identify differentially expressed genes (transgenic DEGs) (Supplemental Table 1). Results largely affirmed our qRT-PCR data (Supplemental Figure 2B) and revealed that the panel of transcripts examined in Supplemental Figure 2B represent only a fraction of the VGLL3-regulated transcripts identified in transgenic mice. Of the 120 gene ontology terms significantly enriched (FDR ≤ 10%) among transgenic DEGs, nearly half were related to immunological processes (Supplemental Figure 2C). Importantly, these included multiple key pathways involved in SLE pathogenesis, such as IFN responses. Literature-based network analysis of transgenic DEGs revealed additional nodes of autoimmune pathogenesis (Figure 2C). To further explore our hypothesis that female-biased VGLL3 expression in human skin drives gene changes that may predispose women to autoimmunity, we compared transgenic DEGs with the set of genes upregulated in healthy human female skin relative to male skin (3) and found a significant overlap (P = 0.032). To evaluate for a direct effect of VGLL3 overexpression in keratinocytes of our mouse model, we cultured primary keratinocytes from WT and transgenic mouse tails and performed RNA-seq. Genes differentially expressed in transgenic keratinocytes also demonstrated enrichment for immunological gene ontology terms, such as immune response (P = 6.8 × 10–9) and cytokine activity (P = 1.2 × 10–8), and showed even more significant overlap with female-biased genes (P = 4.0 × 10–7). Thus, epidermal overexpression of VGLL3 is a prominent driver of immunological dysregulation and sex-biased gene expression in keratinocytes. We then compared our mouse skin RNA-seq results to transcriptomic data from skin of cutaneous lupus patients (7). Genes dysregulated in lesional skin of patients with DLE or subacute cutaneous lupus erythematosus (SCLE) were overrepresented among transgenic DEGs (DLE, P = 1.1 × 10–13; SCLE, P = 5.0 × 10–9) and showed widespread upregulation in transgenic mice (Figure 2D), revealing a shared pattern of gene dysregulation in skin of K5-Vgll3–transgenic mice and lupus patients. Together, these in vivo data demonstrate that VGLL3 overexpression in the epidermis is sufficient to drive a female-biased gene expression signature with dysregulation of pathways implicated in human autoimmune disease. Immunohistochemistry of K5-Vgll3–transgenic skin revealed a mixed inflammatory infiltrate (Figure 3). T and B cells were increased, as were DCs, which promote lymphocyte expansion, autoantibody production by B cells, and tissue damage in SLE (8). Flow cytometry of cells isolated from skin corroborated these findings, demonstrating increased plasmacytoid DCs, as well as IgM+ and IgG+ cells, consistent with B cell expansion (Supplemental Figure 3). Neutrophils were also elevated, consistent with the neutrophilic inflammation noted on some lesional sections (Supplemental Figure 1F) and observed in a significant subset of cutaneous lupus manifestations (9). These results illustrate that epidermal overexpression of VGLL3 results in a cutaneous phenotype with gross, histologic, and inflammatory features of cutaneous lupus.

Ki67, cell proliferation marker; MECA, mouse endothelial cell antigen. Scale bar: 50 μm. Images are representative of sections from 4 WT and 4 TG animals examined. To further interrogate the inflammatory response in the K5-Vgll3–transgenic mouse, we analyzed skin-draining lymph nodes, spleen, and ear tissue from WT and transgenic mice with mass cytometry (CyTOF) using a 37-marker panel (Supplemental Figure 4 and Supplemental Table 2). Transgenic mice showed significant lymphadenopathy and splenomegaly (Figure 4A), features common in SLE and some lupus mouse models (10, 11). CyTOF data visualized using the dimensional reduction tool viSNE (12) showed expansion of B cell populations that were most prominent in skin-draining lymph nodes (Figure 4B and Supplemental Figure 4). Key populations emerging from CyTOF are highlighted in a SPADE tree (13) (Figure 4, C–E, and Supplemental Figure 5). B cells were significantly overrepresented in transgenic lymph nodes (q = 6.2 × 10–4; blue circles in Figure 4D) and spleen (q = 0.024). Together, these findings suggest that skin-directed VGLL3 overexpression drives a systemic inflammatory response with B cell expansion.

Q val, q values for differential detection in WT versus TG LN. †q = 6.2 × 10–4, significantly upregulated in TG LN. Peripheral blood mononuclear cells (PBMCs) of patients with SLE show altered gene expression, with prominent dysregulation of genes in IFN and cytokine signaling pathways that likely contributes to systemic inflammation (14). Evaluating gene expression in blood of WT versus K5-Vgll3–transgenic mice, we observed a significantly higher effect size for genes whose human orthologs are dysregulated in blood of SLE patients (P = 1.6 × 10–22) (Figure 5A and Supplemental Table 3), indicating a shared pattern of gene dysregulation in circulating immune cells of K5-Vgll3–transgenic mice and patients with SLE. Figure 5 Mice with skin-directed VGLL3 overexpression develop manifestations of systemic autoimmune disease. (A) Differential expression in WT (n = 4) and TG (n = 4) mouse blood of genes dysregulated in SLE peripheral blood mononuclear cells (aqua) versus all genes (peach). (B) Detection at 1:50 dilution of circulating antinuclear antibodies (Ig) by indirect IF in HEp-2 cells in WT, TG, and positive control (+ control, aged NZM2328) serum. In total, 7 TG and 3 WT animals were evaluated; all TG mouse sera showed positive autoantibody staining at a dilution of 1:25 or higher, whereas all WT mouse sera were negative. (C) Detection of circulating anti–double-stranded DNA antibodies (α-dsDNA) by ELISA. Error bars represent mean ± SEM. ***P = 0.0005 by 2-tailed Student’s t test. n = 6 WT and 6 TG. (D) Detection of IgG (red) and complement factor C3 (green) by IF in WT and TG glomeruli. Blue, DNA. Scale bar: 20 μm. Images are representative of glomeruli visualized on sections from 6 WT and 6 TG animals examined. 0 of 6 WT and 6 of 6 transgenic mice scored positive for renal immune complex deposition. Finally, we investigated whether the B cell expansion of the K5-Vgll3 mouse was associated with autoantibody production. Autoantibodies are integral to pathogenesis of SLE and associated with increased risk of progression from cutaneous to systemic lupus (15). Commonly used SLE classification systems include their detection as a diagnostic criterion. By indirect IF of HEp-2 cells, antinuclear antibodies were detected in sera of transgenic mice with developed phenotypes (Figure 5B). A homogeneous pattern of nuclear staining was observed, which is commonly found in SLE patients. Anti–double-stranded DNA (anti-dsDNA) antibodies, which are a specific marker for SLE and fluctuate with disease activity (16), were abundant in sera of transgenic mice (Figure 5C). As anti-dsDNA antibodies are pathogenic to the kidney (17), we examined kidneys of transgenic mice and found IgG and C3 deposition in glomeruli (Figure 5D). Most transgenic mice were harvested by 4–5 months of age due to the severity of the skin phenotype, limiting time for evolution of fulminant nephritis; nonetheless, examination of the transgenic kidneys revealed a subtle trend toward increased inflammation relative to WT kidneys (P = 0.20; Supplemental Figure 6, A and B). As expected based on the mild histology, significant proteinuria was not detected (P = 0.19; Supplemental Figure 6C). Thus, skin-directed VGLL3 overexpression stimulates development of lupus-specific anti-dsDNA autoantibodies that results in immune complex deposition in the kidney, the purported initiating event in development of lupus nephritis (17). Discussion Female sex alone carries a greater risk for developing SLE than any genetic or environmental factor identified to date (18). Previously, we determined that women express an autoimmunity-prone genetic signature in their skin. We hypothesized that this program was driven by the putative transcription cofactor VGLL3, which is upregulated and nuclear localized in the skin of healthy women and SLE patients of both sexes (3). Here, we establish that skin-directed overexpression of murine VGLL3 is sufficient to drive an autoimmunity-prone transcriptional signature similar to that observed in female skin, causing inflammation and activation of type I IFN signaling that mimics cutaneous lupus. Intriguingly, although VGLL3 overexpression in our model was restricted by the bovine K5 promoter to keratinocytes and some other squamous epithelia (4), K5-Vgll3–transgenic mice developed systemic inflammation, with B cell activation and autoantibody production that culminated in renal immune complex deposition analogous to that seen in lupus nephritis. Thus, overexpression of a single female-biased gene is sufficient to trigger cutaneous autoimmune disease accompanied by a systemic autoimmune response with striking similarities to SLE. This includes development of anti-dsDNA antibodies, whose presence constitutes an independent risk factor for lupus nephritis (19), and detection of immune complexes in the skin and kidneys. A growing body of evidence suggests that, in autoimmune disease pathogenesis, the initial break in self-tolerance — the inciting “first hit” — occurs at epithelial surfaces. In rheumatoid arthritis, localized mucosal tissue damage may lead to posttranslational modification of peptides, resulting in formation of anti-citrullinated peptide antibodies (20), autoantibodies that often precede the onset of disease and in susceptible individuals may incite it (21). In antinuclear antibody–associated diseases, such as SLE and other connective tissue diseases, the first hit may occur in the skin. In patients with SLE, clearance of apoptotic cells is impaired (22). Insults, such as ultraviolet light, which induces immunological activation and apoptosis of keratinocytes, cause release of endogenous nuclear antigens. Presence of these autoantigens results in elaboration of cytokines and immune cell recruitment, and cytotoxic inflammation perpetuates their release, with resulting accumulation and possible entry into circulation as proinflammatory microparticles. Inflammation in the skin may therefore prime or exacerbate antinuclear antigen-focused autoimmunity. There are sparse data suggesting that treatment of cutaneous lupus may prevent progression to SLE (23). The results herein demonstrate that cutaneous disease may be sufficient to trigger a break in self-tolerance with evolution of systemic autoimmune disease. These findings are complemented by reports in mice describing evolution of SLE-like disease with development of anti-dsDNA antibodies and immune complex nephritis in response to epidermal IFN-γ overexpression (24, 25). Further study of the IFN-γ epidermal overexpression and K5-Vgll3 lupus mouse models may reveal that treatment of cutaneous lupus is sufficient to ameliorate or even prevent progression to systemic disease. If so, this could prompt a paradigm shift in our understanding of the pathogenesis of SLE. Our results do not distinguish a principal pathway promoting autoimmunity in the K5-Vgll3–transgenic mouse. As the VGLL3-regulated factor IFN-κ is the predominant type I IFN in cutaneous lupus (5), this presents a parsimonious explanation; however, VGLL3 alters the expression of genes that act in multiple independent inflammatory pathways, and the lupus-like phenotype of the K5-Vgll3–transgenic mouse may represent the cumulative manifestation of widespread immunological VGLL3-induced dysregulation. This is reflected in the diverse inflammatory pathways activated in the skin of transgenic mice (Figure 2C), many of which have key roles in autoimmunity: MHC class I, antigen binding, cytokine activation, humoral immune responses, cellular response to IFN, and regulation of T cell–mediated cytotoxicity (26). The significant overlap of VGLL3 targets with genes dysregulated in female skin suggests that the transgenic mouse phenotype represents a fully developed autoimmune disease of which female-biased autoimmunity is the forme fruste. Additional studies of the component inflammatory pathways in the K5-Vgll3 lupus model are required to dissect the pathogenesis further. Finally, one of the principal challenges of treating lupus is disease heterogeneity. Broad immunosuppressants address disease in a majority of patients but carry serious risks of infection and malignancy that contribute substantially to morbidity and mortality. In contrast, narrower agents, such as belimumab, the biologic therapy that targets BAFF, are effective only in a subset of patients where presumably the disease is driven more heavily by the targeted autoimmune pathway. As VGLL3 appears to be not only constitutively active in women but also turned on in men with SLE (3), targeting VGLL3 may prove beneficial in patients of both sexes. Additionally, the low levels of VGLL3 in healthy men suggest that it may be amenable to depletion without adverse effects. Given stimulation of diverse inflammatory pathways — including those involving type I IFN and BAFF — observed in the K5-Vgll3–transgenic mouse, VGLL3 depletion may successfully treat more subgroups within this heterogeneous patient population. In conclusion, our data support the assertion that enrichment of VGLL3 in female skin primes women for autoimmunity. This positions VGLL3 as a master orchestrator of sex bias in autoimmune disease, providing potentially novel avenues for future research and therapeutic development. Methods Mice, primary keratinocyte isolation, and culture The K5-Vgll3-IRES-tdTomato–transgenic (K5-Vgll3–transgenic) cassette was generated as follows. The Vgll3-IRES-mCherry insert was synthesized de novo by GenScript and subcloned into the pBK5 vector, in which the bovine K5 promoter drives expression primarily in epidermis but also in some other stratified squamous epithelia (4). Of note, expression of this specific promoter has been reported to be absent in thymus and spleen (4, 27), indicating no significant expression in the immune cells therein. The Vgll3 coding sequence was taken from NCBI reference sequence NM_028572.1. The mCherry coding sequence was taken from GenBank (accession AY678264, nt 1–711) (28). Following sequence verification, the transgenic cassette was isolated by restriction enzyme digest, purified, and injected into C57BL/6 mouse oocytes at the University of Michigan Transgenic Core. Founders were identified by PCR using the following PCR primers: forward, 5′-ATCGTGCCAAGTGTGGGCTTCGATACA-3′ (located in the Vgll3 coding sequence), reverse, 5′-CACATTGCCAAAAGACGGCAATATGG-3′ (located in the IRES) and were crossed with C57BL/6J breeders (The Jackson Laboratory) to establish transgenic lines. Transgene-positive offspring were screened for cutaneous phenotypes. Nine independent founder lines were generated that demonstrated spontaneous development of cutaneous phenotypes; progeny of 6 additional independent founders either failed to develop phenotypes or were harvested for experimental purposes prior to development of phenotypes. Phenotypes observed were overall fairly uniform and typically involved alopecia and ulceration that progressed with age, often necessitating euthanasia; transgenic animals from 6 independent founder lines are pictured at time of euthanasia in Supplemental Figure 1C. Transgenic mice were observed scratching and excessively barbering, and some transgenic animals were noted to be excessively barbering nontransgenic littermates. K5-Vgll3–transgenic mouse skin harvested from multiple sites was evaluated by fluorescent microscopy of transgenic mCherry to verify epidermal transgene expression (tail, Figure 1C). For RNA-seq analysis of nonlesional (posterior dorsal) skin and blood, 4 transgenic animals representing 3 independent founder lines were included (see below for associated methods). For RNA-seq analysis of transgenic and WT primary keratinocytes, all animals were from a single litter representing 1 founder line to enable simultaneous isolation, culture, and harvest. RNA‑seq analysis of transgenic nonlesional skin and primary keratinocytes confirmed significant Vgll3 mRNA overexpression relative to WT skin and primary keratinocytes, respectively. qRT-PCR also confirmed significant Vgll3 mRNA overexpression, although the variation and upper limit of Vgll3overexpression was greater (generally 5- to 50-fold), possibly due to increase in epidermal thickness. Consistent with prior reports of absent expression in lymphoreticular organs (4, 27), RNA-seq analysis of K5-Vgll3–transgenic blood showed no Vgll3 upregulation that would be suggestive of leakage of transgene expression in immune cells (data not shown). Given the overall similarity in phenotype and gene expression changes noted by RNA-seq analysis of nonlesional skin of 3 different founder lines, multiple founder lines were included throughout the manuscript, including in qRT-PCR analyses. Primary keratinocytes were isolated as previously described from tails of 3 WT and 3 transgenic 23-day-old weanlings from a single litter (29) with the following change: skin was incubated for 1.5 hours at 37°C rather than overnight at 4°C. Cells were expanded in culture for 3 days and harvested for RNA using Buffer RLT (Qiagen) per the manufacturer’s protocol. Tissue collection For harvest of tissues for generating RNA and frozen or paraffin sectioning, transgenic mice and WT controls were euthanized at 8 weeks of age or older. Whole blood was obtained by cardiac stick and RNA was isolated using the Mouse RiboPure-Blood RNA Isolation Kit (Thermo Fisher Scientific) or TriPure Isolation Reagent (MilliporeSigma) per the manufacturer’s protocols. Nonlesional posterior dorsal skin was removed by punch biopsy. Ears were removed in entirety. Skin from the indicated sites was otherwise harvested and processed as previously described (30). For harvest of tissues for mass cytometry (CyTOF) and flow cytometry, sex-matched transgenic and WT littermates were sacrificed at 8 weeks of age or older. Ears, spleen, and skin-draining (cervical and inguinal) lymph nodes were removed in entirety. The ear and dorsal skin samples were minced with a sterile razor and transferred to 18 ml RPMI (Gibco) containing 10% fetal calf serum (Atlanta Biologicals) and 1% Penicillin-Streptomycin (Gibco) (hereafter, RPMI complete media). To each sample, 2 ml of a skin digestion solution consisting of Hanks’ Balanced Salt Solution (Gibco) with 1 mg/ml DNAse I (MilliporeSigma), 1 mg/ml Hyaluronidase type V (MilliporeSigma), and 5 mg/ml Collagenase type IV (MilliporeSigma) was added. Samples were rotated for 2 hours at 37°C to digest. Following digestion, samples were filtered through a 40-μm cell strainer, washed with fresh RPMI complete media, and incubated on ice. Spleens and lymph nodes (4 lymph nodes combined for each animal) were weighed before being ground through a 70-μm cell strainer and suspended in RPMI complete media. For spleen samples, media were removed, and cells were incubated in RBC lysis buffer (Invitrogen) for 2 minutes. Lysis buffer was removed, and spleen samples were resuspended in fresh RPMI complete media. qRT-PCR RNA was converted to cDNA using a High-Capacity cDNA Reverse Transcription Kit (Applied Biosystems). qRT-PCR was performed in technical duplicates for the biological replicate numbers indicated in the figure legends using TaqMan Universal PCR Master Mix (Applied Biosystems). TaqMan primer sets and probes were purchased from Applied Biosystems by Life Technologies and are listed in Supplemental Table 4. All values were normalized to the housekeeping gene 18S. All qRT-PCR data are presented with y axis log2-scaled and autolog numbered. RNA-seq and gene expression analyses Stranded mRNA libraries were prepared from nonlesional (posterior dorsal) skin, cultured keratinocytes, and whole blood from age- and sex-matched WT and transgenic mice (2 male and 2 female each) using the TruSeq RNA library prep kit (Illumina) and sequenced on the Illumina HiSeq 4000 sequencer at the University of Michigan DNA Sequencing Core. Data were quality controlled and analyzed using the pipeline described previously for RNA-seq analysis, including adapter trimming (31), read mapping, and quantification of gene expression (32). We used the GENCODE release m18 (GRCm38) from mouse. We filtered for average abundance of ≥1 read per gene across all samples. DESeq was used for expression normalization. Generalized linear regression was used for differential expression analysis using negative binomial distribution to model the count data (33). FDR was used to control the multiple testing. DEGs were defined as having FDR ≤ 10% and with |log2fold change| ≥ 1 (Supplemental Tables 1 and 3). For Supplemental Figure 2B, data are presented with y axis after log2 scaling and autologing of numbers for ease of comparison to qPCR data. Software‑extracted literature‑based network analysis was performed using Genomatix Pathway System Software. For identification of genes dysregulated in DLE and SCLE, microarray data from 26 DLE and 23 SCLE lesional skin biopsies and 7 normal skin biopsies (GEO GSE81071) were utilized to identify genes that are differentially expressed in DLE and SCLE skin (termed dysregulated in text to avoid confusion with transgenic DEGs) at the FDR ≤ 10% and with |log2fold change| ≥ 1 threshold. For identification of genes dysregulated in blood of SLE patients, RNA-seq data from whole blood of 99 SLE and 18 healthy control patients were analyzed as above and used to identify genes that were differentially expressed in blood of SLE patients (termed dysregulated in text to avoid confusion with transgenic DEGs). We performed analysis only for genes expressed in at least 20% of the normal samples. For investigation of target overlap with DLE and SCLE skin and SLE blood, only genes with identical names in mouse and human were included. Histology and immunostaining Hematoxylin (Surgipath, 3801540) and eosin (Surgipath, 3801600) staining was performed per standard protocols. Epidermal thickness was quantified on the H&E-stained sections using Adobe Photoshop. For each animal, approximately 100 measurements were taken from 8 different fields of view for each section analyzed. Epidermal thickness was measured from the stratum basale to stratum granulosum, excluding the stratum corneum and hair follicles for each animal. IF to detect VGLL3 and target proteins was performed as follows. For CXCL13 detection, formalin-fixed, paraffin-embedded tissue sections were deparaffinized, rehydrated, and heated at 95°C for 20 minutes in pH 6 antigen retrieval buffer. Slides were blocked and incubated with goat anti-mouse CXCL13 antibody (R&D System, AF470-SP) overnight at 4°C. For VGLL3 and IFN-κ detection, cryosections were subjected to acetone fixation. Slides were blocked and incubated with rabbit anti-mouse VGLL3 antibody (St. John’s Laboratory, STJ115228) or sheep anti-mouse IFN-κ antibody (R&D System, AF5206), respectively. All slides were then incubated with biotinylated secondary antibodies (Vector Laboratories) as appropriate, incubated with fluorochrome-conjugated streptavidin (Streptavidin, Alexa Fluor 488 conjugate [Thermo Fisher Scientific, S32354] or Streptavidin, Alexa Fluor 594 conjugate [Life Technologies, S32356]) as appropriate and mounted. Images were acquired using Zeiss Axioskop 2 microscope and analyzed by SPOT software V.5.1. PAS staining of paraffin sections was performed using the Periodic acid–Schiff (PAS) staining system (MilliporeSigma) per the manufacturer’s instructions (see procedure 395). TUNEL staining of paraffin sections was performed using the In Situ Cell Death Detection Kit, TMR red (Roche). Slides were mounted with ProLong Gold Antifade Mountant with DAPI (Thermo Fisher Scientific). IF of immune complex components was performed as follows. Slides with tissue cryosections were dried for 1 hour at 37°C, incubated in 4% paraformaldehyde for 20 minutes, and blocked. C3-FITC (ICL, GC3-90F-Z) and IgG-Texas Red-X (Thermo Fisher Scientific, T-862) goat anti-mouse antibodies were then added, and slides were incubated at 4°C for 1 hour. Hoechst stain (BD Biosciences, 561906) was added. Slides were dried and mounted using ProLong Gold Antifade Mountant (Thermo Fisher Scientific). Images were captured as above. For renal immune complex deposition, 10 glomeruli were assessed for each mouse, and mice were considered positive if more than one glomerulus demonstrated deposition of C3 and IgG. Immunohistochemistry of frozen sections was performed as previously described (30) using antibodies specific for CD4 (BD Biosciences, 550280), CD8a (BD Biosciences, 550281), CD11c (BD Biosciences, 550283), CD19 (BD Biosciences, 550284), F4/80 (eBioscience, 14-4801-82), Ki-67 (DAKO, M7249), and MECA-32 (Developmental Studies Hybridoma Bank, MECA-32-s). Antibodies were detected using either rabbit anti-rat IgG biotinylated (Vector Laboratories), goat anti-rabbit IgG biotinylated (Vector Laboratories), or rabbit anti-hamster IgG biotinylated (Southern Biotech) secondary antibodies, amplified with Avidin/Biotinylated Enzyme Complex (Vector Laboratories), and visualized using the enzyme substrate diaminobenzidine (Vector Laboratories). Slides were counterstained with hematoxylin. Images were captured using a Leica DM L82 microscope with an attached QImaging MicroPublisher 3.3 Mega Pixel camera and Q-capture Pro software. For detection of antinuclear antibodies, serum was taken undiluted, diluted 1:25, or diluted 1:50 and used for indirect IF on Kallestad HEp-2 Slides (Bio-Rad) with FITC goat anti-mouse Ig antibody (BD Biosciences) as the detection reagent. Imaging was performed as for IF above. Mass cytometry (CyTOF) Stimulation. Tissue was harvested and cell suspensions were prepared as above. All samples were then stimulated for 3 hours at 37°C in RPMI complete media with 5 ng/ml phorbol 12-myristate 13-acetate (MilliporeSigma), 1 μg/ml ionomycin (MilliporeSigma), 3 μg/ml Golgistop with Brefeldin A (BioLegend), and 0.67 μl/ml BD GolgiStop Protein Transport Inhibitor with Monensin (Thermo Fisher Scientific), and then incubated on ice until staining. Antibody conjugation with lanthanide metal. The lanthanide metals (Fluidigm) were conjugated to the antibodies using the Maxpar Antibody Labeling Kit (Fluidigm) per the manufacturer’s instructions. Briefly, 2.5 mM Maxpar polymer was preloaded with lanthanide metal at 37°C for 1 hour and buffer exchanged to conjugation buffer using a 3 K Nanosep Centrifugal Device (Pall Life Sciences). The antibody was partially reduced using TCEP at 37°C for 30 minutes and buffer exchanged to conjugation buffer using an Amicon Ultra 0.5-ml 50-kDa Centrifugal Filter Concentrator (MilliporeSigma). The lanthanide-loaded polymer was conjugated to partially reduced antibody following overnight incubation at room temperature. The unbound metal was removed from the metal-tagged antibody by washing with wash buffer in a 50-kDa concentrator. The final concentration of metal-tagged antibody was determined by measuring the absorbance at 280 nm against the wash buffer. See Supplemental Table 2 for the antibodies. Staining of cells with metal-tagged antibodies. Cell-ID Cisplatin-195Pt and Cell-ID Intercalator Iridium-191/193 (Fluidigm) were used to identify live cells. The cells were washed once with prewarmed serum-free media by pelleting at 300 g for 5 minutes at room temperature and stained with 1.25 μM live/dead stain (Cell-ID Cisplatin-195Pt diluted in serum-free media from 500 mM stock) at room temperature for 5 minutes. Free cisplatin was quenched by washing the cells with serum-containing media. CyPBS (1× PBS without heavy metal contaminants, prepared from 10 × PBS stock [Invitrogen] in deionized distilled Milli-Q water [MilliporeSigma]) was used to prepare CyFACS buffer (CyPBS containing 0.1% BSA, 2 mM EDTA and 0.05% sodium azide). The cells were then washed with CyFACS buffer and incubated with TruStain FcX (anti-mouse CD16/32, Biolegends) for 10 minutes at room temperature to block the Fc receptors. For cells surface marker staining, the metal-tagged antibody cocktail was made in CyFACS buffer and added to the cells in the presence of TruStain FcX (BioLegend) and incubated on ice for 60 minutes. Following cell surface marker staining, the cells were washed twice with CyFACS buffer and fixed with 1.6% paraformaldehyde in CyPBS for 20 minutes at room temperature. The cells were then washed and stored overnight at 4°C in CyFACS buffer. The following day, the cells were pelleted at 800 g for 5 minutes and permeabilized with eBioscience permeabilization buffer (Thermo Fisher Scientific) for 30 minutes at room temperature. The cells were then stained with intracellular staining metal-tagged antibody cocktail (made in eBioscience permeabilization buffer) at room temperature for 60 minutes. Following intracellular staining, the cells were washed once with permeabilization buffer and twice with CyFACS buffer and stained with 62.5 nM Cell-ID Intercalator Iridium-191/193 (diluted in 1.6% paraformaldehyde in PBS from 500 μM stock) at room temperature for 40 minutes or left at 4°C until ready for acquisition on CyTOF. CyTOF analysis of samples stained with metal-tagged antibodies. The samples were acquired using CyTOF Helios system (Fluidigm). The system was maintained and tuned according to the manufacturer’s instructions. In addition, internal vendor-set calibration was performed before acquiring samples. The fixed cells were washed twice with CyPBS and deionized distilled Milli-Q water and filtered through a 40-μM cell strainer. EQ Four Element Calibration Beads (Fluidigm) were added at the recommended concentration to the samples before acquisition on CyTOF. The samples were acquired on CyTOF at approximately 50–300 events/s. After acquisition, the instrument software applied a signal correction algorithm based on the calibration bead signal to correct for any temporal variation in detector sensitivity. CyTOF data analysis Total events were gated to remove noncellular events (negative for DNA intercalator), dead cells (uptake of cisplatin), and doublets (event length greater than 25). A viSNE was performed using combined lymph node (~20,000 events/sample), spleen (~20,000 events/sample), and ear (between 262 and 1234 events/sample) samples using Cytobank (34). All antibody channels were included in the viSNE analysis except for IL-17f, as it was suspected this marker was staining nonspecifically (37 included markers). The viSNE run was performed with 2000 iterations, a perplexity of 30, and a θ of 0.5. A spanning-tree progression analysis of density-normalized events (SPADE) clustering algorithm was performed on the same events used in the viSNE analysis using the Cytobank platform (13). As with the viSNE analysis, all antibody channels were included except for IL-17f, as we suspected this marker was staining nonspecifically (37 included markers). After some experimentation, it was found that 50 nodes with 100% event downsampling gave an adequate resolution of cellular subsets. SPADE nodes were manually bubbled based on defined phenotypic markers of major cellular populations (summarized in Figure 4E). Samples were compared based on the percentage of total cells from that sample contained within a bubble or individual node. Flow cytometry WT and transgenic ear tissue was harvested and cell suspensions were prepared as above. Cells were resuspended in blocking reagent of 1% BSA (Fisher Bioreagents) and 1% Horse Serum (Corning) in PBS. Antibody master mixes were prepared using antibodies specific for IgG-PerCP (BioLegend, 405334), IgM-APC (BioLegend, 406509), PDCA-1-APC (BioLegend, 127016), Cd11c-Pacific Blue (BioLegend, 117322), F4/80-Pacific Blue (BioLegend, 123124), and Ly-6G-PE (BioLegend, 127606) and added to each sample. Samples were incubated at room temperature in a dark environment for 45 minutes, washed with PBS, and resuspended in 4% paraformaldehyde in PBS (Affymetrix). Flow cytometry was performed with a BD LSR II (BD Biosciences). After manual gating to exclude dead cells and debris, data corresponding to all remaining cells were analyzed and visualized using FlowJo software (Tree Star). Detection of autoantibodies Anti–dsDNA antibodies were detected in serum using the Mouse anti-dsDNA IgG2a ELISA Kit (Alpha Diagnostic International) according to manufacturer’s instructions. Renal pathology scoring Kidneys from 4 WT and 4 transgenic animals were analyzed. A semiquantitative scoring system (0, no involvement; 0.5, minimal involvement of <10% per section; 1, mild involvement of 10%–30% of section; 2, moderate involvement of 31%–60% of section; and 3, severe involvement >60% of section) was used to assess 13 different parameters of activity and chronicity: mesangial hypercellularity, mesangial deposits, mesangial sclerosis, endocapillary cellular infiltrate, subepithelial deposits, subendothelial deposits, capillary thrombi, capillary sclerosis, cellular crescents, organized crescents, synechiae, tubular atrophy, and interstitial fibrosis. An activity and chronicity index was generated by compiling scores from groups of related parameters. For activity, mesangial hypercellularity, mesangial deposits, endocapillary cellular infiltrate, and cellular crescents were considered; for chronicity, interstitial fibrosis, tubular atrophy, organized crescents, and capillary sclerosis were considered. Analysis of urine albumin/creatinine ratio Urine from 8 WT and 5 transgenic animals was analyzed. Urine was collected from animals within 1 week of euthanasia. Technical duplicates were performed for every sample. To calculate albumin-to-creatinine ratios, urinary albumin was measured using the Albuwell M Kit (Exocell) and urinary creatinine using the QuantiChrom Creatinine Assay Kit (BioAssay Systems), both according to the manufacturer’s protocol. Data availability RNA-seq data have been deposited in GEO (GSE128453). CyTOF data have been made publically available in FlowReposity under repository ID FR‑FCM‑Z2Y6 (35). Statistics qRT-PCR data were tested for statistical significance using 2-tailed Student’s t test assuming homoscedasticity. Significance was defined as P ≤ 0.05. RNA-seq data were tested for normality, and statistical significance was calculated using a 2-tailed Student’s t test, Mann-Whitney U test, or Friedman’s test, as appropriate. For CyTOF data, statistical analysis on the bubbled SPADE populations was performed using Prism 8.0 (GraphPad). P values were computed using unpaired Student’s t tests assuming homoscedasticity. P values were considered discoveries if they fell below an FDR of 10% using the 2-stage step-up method of Benjamini, Krieger, and Yekutieli (36).

  6. APRIL 2019 11 April 2019 by Professor Graham R V Hughes MD FRCP Easter comes late this year. Frenetic Brexit politics – the Westminster establishment fighting to overturn the ‘popular vote’. So sad. Last week I gave a lecture at an ‘immuno-therapy’ meeting in Madrid. Three hundred attendees, including representatives of the Spanish patients’ APS Society. The atmosphere was fantastic. So many doctors (and patients’) wanting to learn more about our syndrome. Talking about ‘learning more’, we now have a date for our own Patients’ Meeting – Friday, 13th September 2019. (For details of the programme and admission, please visit our website: www.ghic.world). This year we are opening up the meeting to include topics on Sjogren’s and lupus, as well as antiphospholipid syndrome. I will also send this blog, as well as details or our annual Patients’ Meeting, to our colleagues in Spain. Patient of the Month “I still feel tired all the time”. Mrs J.S. aged 55, was referred by her G.P. complaining of a variety of symptoms, including aches and pains, headaches, constipation, pins and needles and mental sluggishness. Above all else, she felt constantly fatigued. Despite this very full set of symptoms, the diagnosis remained uncertain. The pins and needles in both hands were put down to carpal tunnel syndrome. But there was little else to find. In view of the frequent headaches, Mrs J.S. was referred to a neurologist who arranged for further tests, including a brain MRI (which showed two small ‘dot’ lesions – reported as probably not significant. To her credit, the neurologist considered lupus and arranged lupus blood tests among the more routine ones. The tests came back showing a normal blood count. However, the ESR (the guide to inflammation) came back ‘borderline positive’ at 35 (normal under 20). The tests for lupus were essentially negative (anti-DNA negative, ANA ‘weak’ (1 in 80). What is the diagnosis (1)? The penny dropped. Could this be thyroid? Bilateral carpal tunnel syndrome is certainly seen in ‘low thyroid’, and significantly Mrs J.S. had a sister with ‘Hashimotos thyroiditis’ – and underactive thyroid with auto-immune features. As with all her other tests the thyroid blood tests were ‘borderline’. Nevertheless, the fatigue, the constipation, the aches and pains, could all be down to ‘low thyroid’. Following a *‘kerbside consult’, with her endocrinology colleague, she instituted thyroxine treatment. Within 2 months the pins and needles were gone and the mental sluggishness, as well as the constipation, were improving. BUT – the aches and pains and the fatigue remained – as bad as ever. What is the diagnosis (2)? It turned out that Mrs J.S. had suffered a series of miscarriages in her early 20’s and she and her husband remained childless. Could the problems – especially the frequent headaches – be due to Hughes Syndrome? Sure enough the antiphospholipid antibody (aPL) tests were strongly positive – not even ‘borderline’. She was started on clopidogrel (‘Plavix’) – an anti-clotting drug similar to aspirin (Mrs J.S. had previously tried aspirin but found it caused indigestion. Result? An almost immediate lessening of the headaches. And, if anything, a further improvement in her memory problems. BUT: no improvement in the fatigue or the aches and pains. What is the diagnosis (3)? Mrs J.S. was referred to a lupus clinic. Again, the results were similar (‘borderline’ ANA and negative anti-DNA). The lupus clinic doctor had seen this before – possible ‘Sjogren’s syndrome’. And, sure enough, the Shirmer’s test – a simple ‘blotting paper’ eye test was completely dry – a useful and very inexpensive screening test for the dry eyes of Sjogren’s Syndrome. Low dose hydroxychloroquine (Plaquenil) (one a day) was started. Three months later at follow-up clinic, ‘fatigue gone. Aches gone. Back to normal life”. What is this patient teaching us? I often talk of ‘The Big Three’ diseases – Lupus, Sjogren’s and Hughes Syndrome, which can overlap clinically However, the world of auto-immune diseases in which I practice includes another ‘big three’, which frequently go together : Hughes Syndrome, Sjogren’s Syndrome and low thyroid (often, specifically, Hashimoto’s thyroiditis) – three ‘named’ syndromes. Clearly, to miss one or even two of the triad would be an ‘under-treatment’. The three conditions can have similar features. And fortunately, potentially very successful treatment – thyroid, aspirin (or Plavix) and hydroxychloroquine. I call the combination of aspirin and hydroxychloroquine (derived from quinine) my ‘two trees’ – treatment –willow and cinchona. Perhaps the biggest lesson from this patient is that there may be more than one diagnosis causing the problems.

  7. An Increased Risk of Dementia Possible in Lupus Stephanie Pappas Jul 13, 2016 Neuropsychiatric symptoms have long been known to affect some patients with systemic lupus erythematosus. But now, emerging evidence suggests that lupus patients may be at increased risk of dementia, as well. A retrospective study published in April in the journal Arthritis Care and Research used the Taiwan Longitudinal Health Insurance Database 2005, a random sampling of the 99.9 percent of Taiwanese citizens covered by the country's national health insurance, to compare dementia rates in people with systemic lupus erythematosus to age- and sex-matched patients without the autoimmune disease. The analysis revealed a doubled rate of dementia in SLE patients. There were 357 cases per 100,00 person-years in the lupus cohort, compared with 180 cases per 100,000 person-years in the non-SLE cohort. {Crude hazard ratio 1.92, 95 percent CI, 1.14−3.23, P< 0.001.) Dementia is a condition of gradual decline, while neuropsychiatric SLE usually manifests early in the diagnosis, wrote study author Dr. Yu-Ru Lin of Taipei Medical Hospital and colleagues. Antiphospholipid antibodies might put patients at risk of micro-stroke, they hypothesized. Alternatively, anatomical changes in the brain attributable to the disease or corticosteroid treatments may contribute to cognitive decline. Rheumatology Network spoke with Dr. Yehuda Shoenfeld, an autoimmunity researcher at Tel Aviv University in Israel, for a deeper look at the dementia-lupus connection. Though not involved with the Taiwanese study, Dr. Shoenfeld has conducted research on lupus autoantibodies and has written about neuropsychiatric lupus in the clinic. He provided his perspective on the need to better understand how lupus might affect the brain. RN: Obviously, neurologic symptoms are well-known in systemic lupus erythematosus. What is the difference between central nervous system lupus and dementia? Shoenfeld: There are neurological, physical findings and also X-ray findings in which you see defects in neurological functions, mainly nerves which can be motor or sensory or so forth. It can be represented by conversions. It can be represented by paralysis. It can be presented as paresthesia, which means it feels like ants are going on your body. So it's more in the domain of physical examination. Dementia is more that you lose your capacity for cognition, memory or so forth. You cannot detect it by X-rays, but you can detect it by talking to the patient and listening to him and you can see that he's not finding himself, I would say, in space. So this is a big difference. What is new about this study by Lin and colleagues? So far we knew that CNS lupus is quite common, 20 percent of the patients can suffer from that. There are many manifestations of CNS lupus from paralysis to conversion, from deafness to blindness, from paresthesia to pains and so forth. Dementia up until now was not part of the story of lupus - neither in regular lupus nor in CNS lupus. We did have psychotic attack in CNS lupus, which could be completely resolved upon proper therapy, for instance with corticosteroids or immunosuppressive drugs. Suddenly, there is dementia. Now, I want to remind you that lupus is a disease of young females, so it's not elderly females with dementia at this age. So the people who published the paper came with the idea that in those patients with CNS lupus, you can find, eventually, more dementia, which is a new revelation, not known so far. With my colleague, Professor Howard Amital [of Sheba Medical Center], an expert on Big Data — we asked the computer to cross the word dementia with SLE in a health database, but we did something else in this respect. We compared it to two other autoimmune diseases. I have to say that, to my great surprise, we have found also that patients with SLE have a threefold increase in dementia. We were not able so far to segregate it to the different factor that we would like to, but we found also with rheumatoid, there was an increase. There was no increase, for instance, in Behcet's syndrome. So most probably, these results are correct, and they should raise a red light. We will analyze our results and we will publish it very soon. But I think it's interesting, even though I had not believed this when I had received the paper from you. What kind of mechanisms might explain why there could be this link? When you have an organic damage to the brain, being autoimmune in nature, being the position of autoantibodies, being the position of other factors it causes chronic damage to the brain and eventually, there is some kind expression that above this threshold it can cause the psychological defects which are expressed as dementia. It's like accumulating damage. Given what is known right now, what is the message for practicing rheumatologists? Before we do anything with patients, we should confirm the results and indeed analyze what could be the mechanism and then eventually work on this to see how we could prevent this. Maybe, for instance, a very quick recovery should be installed whenever there are any signs of CNS lupus. We have to see if, indeed, it's limited only to patients with CNS lupus. There is a lot to analyze now, to learn, to study and to draw conclusions for the future. References: Lin Y-R, Chou L-C, Chen H-C, Liou T-H, Huang S-W, Lin H-W.

  8. SLE Patients at Higher Risk for Some Blood Cancers, Study Says FEBRUARY 18, 2019 BY JOANA CARVALHO IN NEWS. Click Here to receive Lupus News via e-mail Systemic lupus erythematosus (SLE) patients have a higher risk for certain cancers — including cervical, thyroid, ovarian, and oral cancer, as well as lymphoma, multiple myeloma, and leukemia — than the general population, emphasizing the importance of cancer screening programs as part of SLE management. The findings of the study, “Systemic lupus erythematosus is a risk factor for cancer: a nationwide population-based study in Korea,” were published in Lupus. SLE, the most prevalent form of lupus, is a chronic autoimmune disease characterized by behavioral and psychological symptoms including pain, fatigue, depression, and impaired cognition. Previous studies have suggested that SLE patients are more likely to be affected by certain types of cancers, including non-Hodgkin’s lymphoma, lung, liver, and vaginal cancer. “However, some studies have found a decreased risk of some hormone-sensitive cancers, such as breast, ovarian, and endometrial cancer, in SLE patients. However, whether patients with SLE have increased or decreased risk of breast cancer remains unclear,” the researchers said. In this study, investigators set out to characterize the relationship between SLE and cancer in the entire Korean population. The nationwide, retrospective, cohort study involved 21,016 SLE patients and 105,080 age- and sex-matched controls without SLE. The cohort was selected from the Korean National Health Insurance Service (NHIS) database between 2008 and 2014. Over a follow-up period of seven years, 763 (3.36%) SLE patients and 2,667 (2.54%) controls developed cancer. The incidence risk of cancer was higher in SLE patients compared to controls (6.427 vs 4.466). Incidence risk refers to the chance of a disease happening over a defined period of time. After accounting for age and sex, SLE patients showed a 44% higher risk of developing cancer. No differences in cancer risk were found between female and male SLE patients. SLE patients at higher risk for cancer were younger (under 40) and male, being 12 and 29 times more likely of developing lymphoma than control subjects. Looking at different cancer types, researchers found that SLE patients were more likely to develop cervical, thryoid, ovarian, and oral cancer, as well as lymphoma, leukemia, and multiple myeloma than controls. On the other hand, no significant differences in the risk of stomach, colorectal, liver, pancreatic, lung, breast, prostate, biliary, laryngeal, renal, bladder, nerve, and skin cancer were found between SLE patients and controls. While the mechanisms leading to increased risk of cancer in SLE patients are yet to be fully understood, the findings highlight the need for cancer screening programs among this patient population. “In conclusion, SLE is an independent risk factor for malignancy, especially cervical, thyroid, ovarian, oral … as well as lymphoma, multiple myeloma, and leukemia. The importance of cancer screening programs should be emphasized in SLE patients,” the scientists concluded. https://lupusnewstoday.com/2019/02/18/sle-patients-may-be-at-higher-risk-of-developing-certain-types-of-cancer/?utm_source=LUP+NEws+E-mail+List&amp;utm_campaign=1e70fc3e85-RSS_WEEKLY_EMAIL_CAMPAIGN_US&amp;utm_medium=email&amp;utm_term=0_50dac6e56f-1e70fc3e85-71887989
  9. Congratulations and Many Thanks to Lady Gaga! To the entire world, Lady Gaga is a winner. But to the lupus community she’s a hero. Last night at the 2019 Grammy’s, she won an award for Best Pop Solo in honor of her aunt Joanne who lost her battle with lupus at 19. Afterwards she tweeted: Lady Gaga has shared the song’s significance on social media. “I have carried a deep grief in my heart over my family’s tragedy. The loss of Joanne affected my father so deeply that it affected me. When he cried, I cried. When he was angry, I was angry. When he was hurt, I hurt. Today I transform this grief to hope and healing. After 10 years with you I still get nervous before the Grammys, but I know I have an angel with me.” Hear about lupus research from Lady Gaga's dad And watch this video to hear directly from Lady Gaga’s dad, Joe Germanotta, about why he has honoured his sister by actively supporting the Lupus Research Alliance. As a member of our Board of Directors, Joe believes that the research funded by the Lupus Research Alliance is where hope begins. Where our funded research discoveries are breaking through to deliver better treatments and a cure!

  11. Sex Differences in Lupus Mortality Mariah Zebrowski Leach, JD, MS Monday, December 4, 2017 Lupus A comprehensive US population-based study identified an average 22-year and 12-year deficit in life expectancy among females and males with systemic lupus erythematosus (SLE), respectively, compared with the general population. Background In the United States, SLE is a source of significantly decreased life expectancy. While marked differences have been observed between the sexes in terms of the incidence, prevalence, and clinical manifestations of SLE, this area is still poorly understood. Falasinnu and colleagues1 at Stanford School of Medicine identified sex-based differences in the causes of death among SLE decedents in the United States and recognized clinically relevant comorbidities that may warrant careful consideration in patients’ clinical management. The study This study examined SLE-related deaths using the 2014 National Center for Health Statistics multiple cause of death (MCOD) database, a population-based electronic medical recording of all death certificates issued in the United States. The analysis considered not only the number of death certificates listing SLE as the underlying cause of death, but also those listing SLE in general. Demographic information considered included age, race/ethnicity, sex, educational attainment, foreign-born status, marital status, and pregnancy status. SLE decedents were compared with non-SLE decedents in the general population belonging to the same age group. The findings In 2014, there were 2,660,497 deaths in the United States, of which 2036 (0.1%) listed SLE among the causes of death. Approximately 86.2% of SLE deaths occurred among females, with a median age at death of 59 years and the highest proportion of deaths occurring between 45 and 64 years of age. In comparison, the overall median age at death for females in the general population was 81 years, and the majority of deaths occurred among females over 65 years of age. Black females experienced the greatest burden of SLE mortality. Approximately 32% of all female SLE decedents were black, compared with only 11% of non–SLE-related deaths in the general population. Female decedents with SLE had a slightly higher proportion of foreign-born individuals than the general population, but there were no other significant demographic differences. The most frequently listed comorbidities among female decedents with SLE were septicemia (4.32%) and hypertension (3.04%). Among male decedents with SLE, the median age at death was 61 years, compared with 73 years in the general population. Of male decedents with SLE, 23.5% were black, compared with only 12% in the general population. The age-standardized mortality was highest among American Indian males. There were no other demographic differences related to SLE among male decedents. The most frequently listed comorbidities among male decedents with SLE were heart disease (3.70%) and diabetes mellitus with complications (3.61%). Implications for physicians and future research This study offers an opportunity to better describe the association between SLE and related comorbidities in the context of mortality, although the MCOD data have a number of limitations. Inaccuracy on death certificates can lead to the underestimation of the SLE mortality burden, and researchers were unable to differentiate between causes of death that were related to the natural age process, disease activity, and drug therapy. Still, the MCOD data provide a comprehensive understanding of the population-based burden of SLE mortality. While female SLE patients tend to have more frequent disease exacerbations, male patients appear to have significantly greater multisystemic damage accrual and disease severity. Greater disease severity among male SLE patients may be related to under diagnosis due to selective attention given to females by physicians during clinical decision-making. This potential for gender bias needs to be carefully considered. Racial minorities generally have a disproportionately higher burden of mortality. The scope and degree of these differences in SLE are particularly pronounced, with mortality rates among black females nearly four times as high as those in white females. “Our findings reinforce the urgent need for interventions that reduce morbidity and mortality in patients with SLE to improve health outcomes and ultimately reduce health disparities,” the researchers write. They note that novel translational research programs are currently underway to attempt to address these disparities. Clinically relevant comorbidities also need to be considered more carefully in the course of patients’ clinical management and the natural history of SLE. This study revealed future targets for the investigation of sex-based differences and directions for epidemiological research. “A comprehensive understanding of causes of death and the related comorbidities can improve clinical diagnostic and therapeutic strategies, impact survival outcomes in patients living with SLE, and enhance population-based disease surveillance estimates,” the researchers conclude.

  12. Environmental Factors Tied to Lupus Gregory M. Weiss, M.D. Tuesday, December 5, 2017 Lupus Key points • Ultraviolet light may cause flare-ups in systemic lupus erythematosus (SLE). • The chemicals found in cigarette smoke can worsen the symptoms of SLE. • Estrogen analogues such as oral contraceptives and bisphenol A (BPA), a substance used to make plastic bottles, may increase the risk of SLE. Background SLE affects women and African Americans disproportionately. Dr. Gaurav Gulati at the University of Cincinnati in Ohio points out that even though we have treatments for lupus, a complete understanding of its etiology and progression is lacking. Although genetics clearly plays a role in SLE, it appears that environmental factors may act as triggers in those who are susceptible. Dr. Gulati conducted a review of the literature related to SLE and environmental versus genetic factors; he presented his findings recently in Seminars in Arthritis and Rheumatism. The study A systematic review was conducted that looked at over 100 studies focused on SLE. The results • A triad of factors was found in one study that linked a patient’s genetics, how the patient’s DNA changes over time, and exposure to environmental factors to the development and course of SLE. • Twin studies reveal only a 24% concordance of SLE in identical siblings; this points to a conclusion that a combination of genetic predisposition and environmental factors is involved in the development of lupus. • Heavy metals and other trace elements may be triggers for SLE; uranium, lead, and cadmium are linked to autoimmunity. • Elements such as mercury, nickel, and gold have been implicated in delayed hypersensitivity and inflammation, and a higher rate of lupus has been noted among dental workers. • An increase in SLE has been found in women who take oral contraceptives and in those exposed to xenoestrogens such as BPA, a chemical found in plastics. Implications for physicians • Physicians and particularly rheumatologists who treat patients with SLE should vigorously encourage positive lifestyle modifications such as smoking cessation and avoidance of direct sunlight. • Patients with SLE should be advised to always wear sunscreen. • Rheumatologists should provide regular surveillance to their patients with SLE as changes in disease activity and treatment are warranted.

SLE decedents were compared with non-SLE decedents in the general population belonging to the same age group. The findings In 2014, there were 2,660,497 deaths in the United States, of which 2036 (0.1%) listed SLE among the causes of death. Approximately 86.2% of SLE deaths occurred among females, with a median age at death of 59 years and the highest proportion of deaths occurring between 45 and 64 years of age. In comparison, the overall median age at death for females in the general population was 81 years, and the majority of deaths occurred among females over 65 years of age. Black females experienced the greatest burden of SLE mortality. Approximately 32% of all female SLE decedents were black, compared with only 11% of non–SLE-related deaths in the general population. Female decedents with SLE had a slightly higher proportion of foreign-born individuals than the general population, but there were no other significant demographic differences. The most frequently listed comorbidities among female decedents with SLE were septicemia (4.32%) and hypertension (3.04%). Among male decedents with SLE, the median age at death was 61 years, compared with 73 years in the general population. Of male decedents with SLE, 23.5% were black, compared with only 12% in the general population. The age-standardized mortality was highest among American Indian males. There were no other demographic differences related to SLE among male decedents. The most frequently listed comorbidities among male decedents with SLE were heart disease (3.70%) and diabetes mellitus with complications (3.61%). Implications for physicians and future research This study offers an opportunity to better describe the association between SLE and related comorbidities in the context of mortality, although the MCOD data have a number of limitations. Inaccuracy on death certificates can lead to the underestimation of the SLE mortality burden, and researchers were unable to differentiate between causes of death that were related to the natural age process, disease activity, and drug therapy. Still, the MCOD data provide a comprehensive understanding of the population-based burden of SLE mortality. While female SLE patients tend to have more frequent disease exacerbations, male patients appear to have significantly greater multisystemic damage accrual and disease severity. Greater disease severity among male SLE patients may be related to under diagnosis due to selective attention given to females by physicians during clinical decision-making. This potential for gender bias needs to be carefully considered. Racial minorities generally have a disproportionately higher burden of mortality. The scope and degree of these differences in SLE are particularly pronounced, with mortality rates among black females nearly four times as high as those in white females. “Our findings reinforce the urgent need for interventions that reduce morbidity and mortality in patients with SLE to improve health outcomes and ultimately reduce health disparities,” the researchers write. They note that novel translational research programs are currently underway to attempt to address these disparities. Clinically relevant comorbidities also need to be considered more carefully in the course of patients’ clinical management and the natural history of SLE. This study revealed future targets for the investigation of sex-based differences and directions for epidemiological research. “A comprehensive understanding of causes of death and the related comorbidities can improve clinical diagnostic and therapeutic strategies, impact survival outcomes in patients living with SLE, and enhance population-based disease surveillance estimates,” the researchers conclude.

  14. Treatment Target Shows Promise in Systemic Lupus Erythematosus Mariah Zebrowski Leach, JD, MS Monday, December 4, 2017 The lupus low disease activity state (LLDAS) is a promising treatment target in systemic lupus erythematosus (SLE), according to new research. Background Successfully applied in rheumatoid arthritis as well as in non-rheumatic conditions, a treat-to-target approach aims to improve disease outcomes through the achievement of a pre-specified goal. An international task force suggested such a strategy for the treatment of SLE.1 They recommended that the treatment target should be remission or—when that is unachievable—the lowest possible disease activity. LLDAS is a composite definition of minimal acceptable disease activity proposed by the Asia-Pacific Lupus Collaboration (APLC). LLDAS is based on the following criteria: 1. SLE Disease Activity Index 2000 (SLEDAI-2K) ≤ 4, with no activity in major organ systems 2. No new lupus disease activity compared with the previous assessment 3. Safety of Estrogen in Lupus Erythematosus National Assessment (SELENA)-SLEDAI physician global assessment (PGA) ≤ 1 4. Current prednisolone (or equivalent) dose ≤ 7.5 mg daily 5. Well-tolerated standard maintenance doses of immunosuppressive drugs and approved biological agents To be considered a valid treatment target, LLDAS should be protective against damage accrual in the early SLE stages. Piga and colleagues2 at the University Clinic and AOU of Cagliari in Italy sought to determine the frequency of LLDAS achievement and its association with early damage accrual in a homogenous cohort of Caucasian patients with SLE prospectively assessed during the first 18 months of treatment after diagnosis. The study This study primarily aimed to assess the frequency of LLDAS achievement and its association with early damage, with a secondary aim to identify the main reasons for failure to achieve LLDAS. The study cohort consisted of 107 patients from the Cagliari (Italy) SLE cohort between January 2006 and December 2016. To assess LLDAS as a goal for initial treatment, the primary study endpoint was set at 6 months, with 18 months considered an appropriate time to evaluate the effect of maintenance treatment and early damage accrual. At each visit, disease activity was assessed using the SLEDAI-2K score and the PGA. At 18 months, damage accrual was assessed by the SDI and the possible attribution to corticosteroids was done according to a previous definition. Average daily dose of prednisolone (or equivalent) and ongoing use and new prescription of medications were assessed at every visit. The findings At the 6-month point, LLDAS had been achieved by 47 patients (43.9%). At 18 months, 48 patients (44.9%) were in LLDAS; 33 of them had achieved LLDAS at 6 months and were still in this condition and 15 had reached LLDAS for the first time. Of the 59 patients who were not in LLDAS at 18 months, 45 had never been in LLDAS and 14 had been in LLDAS at 6 months but no longer were at 18 months. Thus, despite a seemingly overall stable LLDAS rate, these results demonstrate the dynamic nature of this condition. On univariate analysis, the following factors were significantly associated with failure to achieve LLDAS at 6 months: renal involvement, higher SLEDAI-2K score, positive (> 10 UL/mL) anti-dsDNA antibodies, lower serum C3 and C4 values, and higher prednisolone dose and immunosuppressant drug use. On multivariate analysis, renal involvement and C4 levels were confirmed to be associated with failure to achieve LLDAS. Implications for physicians The limitations of this study are the relatively small sample size, which may have hampered study results, and the retrospective design, which prevented researchers from testing LLDAS criterion validity by comparing it with other treatment targets such as the SLE Responder Index. Nevertheless, by enrolling consecutively diagnosed patients at the time of treatment initiation and following them prospectively, the researchers were able to provide novel data on LLDAS as a potential treatment target. In this study, the most frequent reason for failure to achieve LLDAS 6 months after therapy initiation was daily prednisolone dosage > 7.5 mg. Damage was definitely attributable to steroid use in 40% of cases in this cohort. However, supported by this data and literature evidence on damage development, the researchers consider 7.5 mg/d an acceptable cutoff to define low disease activity during initial treatment. Still, they recommend a lower cutoff should be targeted to minimize risk of steroid-related damage during maintenance therapy in patients with SLE. In this cohort, patients with renal involvement and serological disorders had the lowest remission rate, and renal involvement at baseline was the most important factor associated with failure to achieve LLDAS. “LLDAS is a promising treatment target in SLE, being attainable and negatively associated with damage accrual in the early stages of the disease,” the researchers write. “However, it seems to poorly fit with the heterogeneity of clinical presentation in patients with SLE, mostly in those with renal involvement,” they conclude.

  15. An evidence-based approach to pre-pregnancy counselling for patients with systemic lupus Y K Onno Teng Edwin O W Bredewold Ton J Rabelink Tom W J HuizingaH C Jeroen Eikenboom Maarten Limper Ruth D E Fritsch-StorkKitty W M Bloemenkamp Marieke Sueters Rheumatology, kex374, https://doi.org/10.1093/rheumatology/kex374 Published: 20 November 2017 Abstract Patients with SLE are often young females of childbearing age and a pregnancy wish in this patient group is common. However, SLE patients are at high risk for adverse pregnancy outcomes that require adequate guidance. It is widely acknowledged that pre-pregnancy counselling is the pivotal first step in the management of SLE patients with a wish to become pregnant. Next, management of these patients is usually multidisciplinary and often requires specific expertise from the different physicians involved. Very recently a EULAR recommendation was published emphasizing the need for adequate preconception counselling and risk stratification. Therefore the present review specifically addresses the issue of pre-pregnancy counselling for SLE patients with an evidence-based approach. The review summarizes data retrieved from recently published, high-quality cohort studies that have contributed to a better understanding and estimation of pregnancy-related risks for SLE patients. The present review categorizes risks from a patient-oriented point of view, that is, the influence of pregnancy on SLE, of SLE on pregnancy, of SLE on the foetus/neonate and of SLE-related medication. Lastly, pre-pregnancy counselling of SLE patients with additional secondary APS is reviewed. Collectively these data can guide clinicians to formulate appropriate preventive strategies and patient-tailored monitoring plans during pre-pregnancy counselling of SLE patients. https://academic.oup.com/rheumatology/advance-article-abstract/doi/10.1093/rheumatology/kex374/4641853?redirectedFrom=fulltext
  16. 21 November, 2017 SAN DIEGO — At the American College of Rheumatology Annual Meeting, Joan Merrill, MD, spoke about a study that she said is further demonstration that atacicept should continue being developed as a potential treatment for lupus. According to Merrill, the results also suggest that measurements of low-disease activity may represent not just clinically meaningful endpoints, but may also “work as endpoints in clinical trials to discriminate drug from placebo.” https://www.healio.com/rheumatology/lupus/news/online/{1b289264-6a9b-47a3-86c6-9b0eb8a3980f}/video-atacicept-is-a-potential-exciting-treatment-for-lupus?utm_source=selligent&utm_medium=email&utm_campaign=rheumatology news&m_bt=1879111151405
  17. Obesity linked to worse outcomes of pain, fatigue, depression in women with lupus November 13, 2017 SAN DIEGO — Among women with systemic lupus erythematosus, obesity appears to be independently linked to worse patient-reported outcomes, suggesting that weight loss may improve outcomes for this population, according to findings presented at the American College of Rheumatology Annual Meeting. “The research that I am presenting at this conference was inspired by previous work that showed that patients with lupus experienced big deferments in patient-reported outcomes, or PROs,” Sarah L. Patterson, MD, a fellow in rheumatology at the University of California, San Francisco, and an author of the study, said in her presentation. “It's also been noted that these deferments in PROs are not fully explained by the severity of their lupus disease or by sociodemographic factors such as poverty. So, we therefore wanted to know whether body composition and, specifically, excess adipose tissue contributes to the worse health-related quality of life and greater symptom burden that we see in this particular patient population.” In the study, Patterson and colleagues identified a sample of 148 patients with SLE (65% white, 14% Asian and 13% African-American; mean age, 48 ± 12.3 years) from the Arthritis Body Composition and Disability (ABCD) study. Eligible participants were women aged at least 18 years who had a diagnosis of SLE that could be corroborated by medical record review. The researchers calculated BMI and fat mass index (FMI). FMI measures total fat mass adjusted for height and was evaluated in the study using whole dual-energy X-ray absorptiometry. Obesity was defined using two designations: FMI of at least 13 kg/m2 and BMI of at least 30 kg/m2. The following four validated patient-reported outcomes were included as dependent variables: disease activity via Systemic Lupus Activity Questionnaire, depressive symptoms via Center for Epidemiologic Studies Depression Scale, pain assessed by SF-36 pain subscale and fatigue measured by SF-36 vitality subscale. Multivariable linear regression was used to analyze correlations of obesity with patient-reported outcomes , adjusted for possible confounding factor (age, race, education, income, smoking status, disease duration, disease damage and prednisone use). Adjusted means for each outcome were then calculated based on the multivariable regression. Of the patients in the sample, 17% had poverty-level income; 86% had education beyond high school; the mean duration of disease was 16 ± 9 years; and 45% were being treated with glucocorticoids. Based on the FMI definition of obesity, 32% of patients met the criteria for obesity, whereas 30% were deemed obese by the BMI definition. The multivariate regression model found that FMI-defined obesity was correlated with worse scores on each patient-reported outcome (greater disease activity, higher levels of depression, more pain and more fatigue). In the analyses that used the traditional BMI of at least 30 kg/m2 criteria, the same correlations were seen between obesity and each of the patient-reported outcomes. “These findings have important clinical implications. The PROs that we measured, particularly pain and fatigue, are known to have profound effects on quality of life, and remain a major area of unmet need in people with lupus,” Patterson said. “In other words, there are many patients with lupus who are treated with aggressive immunomodulatory therapy and these symptoms of pain and fatigue persist. The relationship that we observed between excess fat and worse outcomes really underscores the need for lifestyle interventions for lupus patients who are overweight.” – by Jennifer Byrne Reference: Patterson SL, et al.

  18. Lupus Survival Much Improved, But Plateaued September 25, 2017 | Lupus By Gregory M. Weiss, M.D. Survival rates for patients with systemic lupus erythematosus have plateaued since the middle of the 1990s after a period of major improvement starting in the 1950s. It has been thought that survival in systemic lupus erythematosus has continued to improve over the years, with reports of survival in adults increasing from 50% in the 1950s to more than 95% in the 1990s. Data with regard to survival trends in low- and middle-income countries and at 10- and 15-year periods are limited, so Maria Tektonidou and fellow researchers in Greece sought to describe mortality trends for children and adults with systemic lupus erythematosus and presented their findings in a recent Annals of the Rheumatic Diseases article. The study The authors performed a systematic review of the literature, looking at children and adults with systemic lupus erythematosus. Ultimately included in the final analysis were 171 studies; 125 looked at adult survival rates, 51 at pediatric survival, and 5 at both. Results • Studies in high-income countries showed a steady increase in survival from the middle of the 1950s to 1990. Survival rates have remained stable since then. • Five-year survival in high-income countries is greater than 95% in both adults and children who have systemic lupus erythematosus. • Five- and 10 year survival was lower for children than adults in low- to middle-income countries. Adults • Survival in adults with systemic lupus erythematosus has not continued to improve through the 2000s. • From 2008 to 2016, survival rates for adults with systemic lupus erythematosus in high-income countries at 5, 10, and 15 years were 0.95, 0.89, and 0.82, respectively (95% confidence intervals [CIs], 0.94-0.96, 0.88-0.90, and 0.81-0.83, respectively). • From 2008 to 2016, survival rates for adults with systemic lupus erythematosus in low- to middle-income countries at 5, 10, and 15 years were 0.92, 0.85, and 0.79, respectively (95% CIs, 0.91-0.93, 0.84-0.87, and 0.78-0.81, respectively). Children • From 2008 to 2016, survival rates for children with systemic lupus erythematosus in high-income countries at 5 and 10 years were 0.99 and 0.97, respectively (95% CIs, 0.98-1.0 and 0.96-0.98, respectively). • From 1980 to 2000, survival rates for children with systemic lupus erythematosus in low- to middle-income countries at 5 and 10 years were 0.85 and 0.79, respectively (95% CIs, 0.83-0.88 and 0.76-0.82, respectively). • Listing of systemic lupus erythematosus as the cause of death in all cohorts decreased over time. Implications for physicians • Although survival in adults and children with systemic lupus erythematosus both in high-income and in low/middle-income countries has improved dramatically since the 1950s, further gains have not been realized in the 2000s. • A decreased frequency of deaths attributed to systemic lupus erythematosus may be the result of new immunosuppressive drugs and combination therapies. • No increase in death resulting from cardiovascular events or cancer was seen in adults with systemic lupus erythematosus. • The authors suggested that strides need to be made in determining why survival rates are lower in children than in adults in low- and middle-income countries. http://www.rheumatologynetwork.com/lupus/lupus-survival-much-improved-plateaued?GUID=&rememberme=1&ts=26092017
  19. Women with Lupus Overwhelmingly Have Healthy Pregnancies By Whitney L. Jackson In contradiction to long-standing beliefs, a healthy pregnancy is possible for women who have lupus, says Jill Buyon, M.D., a rheumatologist and lupus specialist from New York University School of Medicine. “Patients with lupus have been under the impression that pregnancy would be a very dangerous thing for them. From the mother’s perspective, the concerns are: Will the mother sustain a lupus flare? For mothers who have once had kidney involvement: How safe is it to get pregnant? Will there be adverse pregnancy outcomes? Will the baby be very small? Will the baby be born so early that it needs to be in the hospital for a long time. And, of course, the scary question is: Will my baby die? These are the outcomes we look at from the perspective of counseling and what we wanted to learn from this study,” she said. Dr. Buyon recently published research in the Annals of Internal Medicine showing that women with relatively inactive lupus without serious flares experienced a normal pregnancy with a positive outcome. Study participants were women, ages 18-to-45, enrolled in the Predictors of Pregnancy Outcome: Biomarker in Antiphospholipid Antibody Syndrome and Systemic Lupus Erythematosus (PROMISSE) Trial. The investigation was multi-center, multi-racial and multi-ethnic. Out of the 385 women followed during the study, 81 percent experienced no adverse events. Overall, 9 percent of pregnancies resulted in premature birth, 4 percent experienced pregnancy loss during the second or third trimester, 1 percent encountered infant death due to pregnancy complications, and 10 percent had very low birth weight. Throughout the study, investigators identified four factors that appeared to increase a woman's likelihood for a negative outcome — high blood pressure during pregnancy, more active lupus during gestation, low platelet count, and a positive lupus anticoagulant test during the first trimester. “The patients who tended to be more sick at the outset, tended to be those who might have an adverse pregnancy outcome. The highest risk factor is the presence of something called a lupus anticoagulant. The presence of this abnormal blood test is very important and one that absolutely all doctors should test for,” Dr. Buyon said. In addition, race and ethnicity — black, Hispanic and Asian — contributed to poor outcomes and was in and of itself, a risk factor. Dr. Buyon said she doubts it is due to socioeconomic factors because the patients were treated by similar doctors in tertiary care centers. She suspects it may be due to genetics, which needs to be explored. Although the findings point to the possibility of healthy pregnancies for this population, Dr. Buyon cautioned women who have high protein levels in urine due to uncontrolled kidney disease could still face significant problems with pregnancy. These women are typically advised to postpone pregnancy until their kidney disease improves. Ten to 15 percent of patients had a moderate flare requiring minimal medication changes, but less than 5 percent of patients had a flare that required high dose steroids or hospitalization. About one in five patients had a renal flare. “The other optimistic perspective was that 225 patients never had kidney disease, but many of them had anti DNA antibodies which is an antibody we worry about in developing renal disease. Only four people developed de novo renal disease. For people who had previous kidney disease ... but were in complete remission, they too had very few renal flares. I think this is very encouraging news for women with past renal disease who really are so worried that maybe they’ll never have a healthy pregnancy, that simply is not true (14:01),” Dr. Buyon said. The hope, she said, is that these findings can be used to inform discussions between doctors and their patients with lupus who are also interested in pursuing pregnancy. Dr. Buyon discusses the study, its findings and implications in the following video with Rheumatology Network. REFERENCES Jill P. Buyon, MD; Mimi Y. Kim, ScD; Marta M. Guerra, MS, et al.

  22. GSK receives FDA approval for a new self-injectable formulation of Benlysta (belimumab) for systemic lupus erythematosus Issued: London, UK GSK receives FDA approval for a new self-injectable formulation of Benlysta (belimumab) for systemic lupus erythematosus GSK announced today that the US Food and Drug Administration (FDA) has approved a new subcutaneous formulation of Benlysta (belimumab) for the treatment of adult patients with active, autoantibody‑positive SLE who are receiving standard therapy. Systemic Lupus Erythematosus (SLE) is the most common form of lupus, a chronic, incurable autoimmune disease producing autoantibodies that can attack almost any system in the body. The approval marks the first subcutaneous self-injection treatment option for patients with SLE. After training from their health care provider, patients will be able to administer the medicine as a once weekly injection of 200mg, from either a single-dose prefilled syringe or from a single-dose autoinjector. This is the second formulation of Benlysta to be granted approval for SLE, adding to the existing intravenous (IV) formulation, approved in 2011, which is administered by healthcare professionals to patients as a weight-based dose of 10mg/kg, via a one-hour infusion in a hospital or clinic setting every four weeks (following an initial loading phase given on days 0, 14 and 28). Vlad Hogenhuis, Senior Vice President, Head of Specialty Care, GSK said, “We are delighted with today’s decision. Lupus can impact the lives of patients in many different ways with varied and often unpredictable symptoms. Since it launched in its IV form, thousands of patients worldwide have received treatment with Benlysta. The approval of the new injectable formulation will now provide an additional choice for patients, allowing them to self-administer their medicine at home rather than going to hospitals or clinics for their infusions.” The approval is based on data from the BLISS-SC phase III pivotal study of more than 800 patients with active SLE, which measured reduction in disease activity at Week 52 in patients receiving belimumab plus standard of care, versus those receiving placebo plus standard of care (assessed by SRI, a composite measure of efficacy in lupus). Benlysta subcutaneous formulation will be available in specialty pharmacies in the US in late August. Further regulatory submissions for the subcutaneous formulation of Benlysta are under review or planned in other countries during the course of 2017. About Benlysta (belimumab) Benlysta is currently the only medicine specifically developed and approved for SLE. Benlysta, a BLyS-specific inhibitor, is a human monoclonal antibody that binds to soluble BLyS. Benlysta does not bind B cells directly. By binding BLyS, Benlysta inhibits the survival of B cells, including autoreactive B cells, and reduces the differentiation of B cells into immunoglobulin-producing plasma cells. Benlysta is indicated in the US for the treatment of adult patients with active, autoantibody‑positive, systemic lupus erythematosus (SLE) who are receiving standard therapy: Limitations of Use: The efficacy of Benlysta has not been evaluated in patients with severe active lupus nephritis or severe active central nervous system lupus. Benlysta has not been studied in combination with other biologics or intravenous cyclophosphamide. Use of Benlysta is not recommended in these situations. Full US prescribing information including Medication Guide will be available in the near future at: gsksource.com. In the meantime, you may request a copy through GSK Communications. Benlysta is licensed in the European Union as an add-on therapy in adult patients with active autoantibody-positive SLE, with a high degree of disease activity (e.g. positive anti-dsDNA and low complement), despite standard therapy. Benlysta subcutaneous formulation is currently not approved in the European Union. For the EU Summary of Product Characteristics for Benlysta, please visit www.ema.europa.eu About systemic lupus erythematosus (SLE) Systemic lupus erythematosus (SLE) is the most common form of lupus, affecting approximately 70 percent of an estimated 5 million people with lupus worldwide. Approximately 170,000-200,000 Americans live with SLE. It is a chronic, incurable autoimmune disease producing autoantibodies that can attack almost any system in the body. Important Safety Information for belimumab Please consult the full Prescribing Information for all the labelled safety information for Benlysta (belimumab). BENLYSTA (belimumab): CONTRAINDICATION BENLYSTA is contraindicated in patients who have had anaphylaxis with belimumab. WARNINGS AND PRECAUTIONS MORTALITY There were more deaths reported with BENLYSTA than with placebo during the controlled period of the intravenous clinical trials. Out of 2,133 patients in 3 clinical trials, a total of 14 deaths occurred during the placebo-controlled, double-blind treatment periods: 3/675 (0.4%), 5/673 (0.7%), 0/111 (0%), and 6/674 (0.9%) deaths in the groups receiving placebo, BENLYSTA 1 mg/kg, BENLYSTA 4 mg/kg, and BENLYSTA 10 mg/kg, respectively. Etiologies included infection, cardiovascular disease, and suicide. In the controlled clinical trial of BENLYSTA administered subcutaneously (N = 836), a total of 5 deaths occurred during the placebo-controlled, double-blind treatment period (0.7% [2/280] of patients receiving placebo and 0.5% [3/556] of patients receiving BENLYSTA). Infection was the most common cause of death. SERIOUS INFECTIONS Serious and sometimes fatal infections have been reported in patients receiving immunosuppressive agents, including BENLYSTA. Caution should be exercised when considering use in patients with severe or chronic infections. Consider interrupting therapy with BENLYSTA in patients who develop a new infection while receiving BENLYSTA and monitor these patients closely. In controlled clinical trials of BENLYSTA administered intravenously, serious infections occurred in 6.0% and 5.2% of patients receiving BENLYSTA and placebo, respectively. The most frequent serious infections included pneumonia, urinary tract infection, cellulitis, and bronchitis. Infections leading to discontinuation of treatment occurred in 0.7% and 1.0% of patients receiving BENLYSTA and placebo, respectively. Infections resulting in death occurred in 0.3% (4/1,458) and 0.1% (1/675) of patients receiving BENLYSTA and placebo, respectively. In the controlled trials of BENLYSTA administered subcutaneously (N = 836), serious infections occurred in 4.1% and 5.4% of patients receiving BENLYSTA and placebo, respectively. Progressive Multifocal Leukoencephalopathy (PML): Cases of JC virus-associated PML resulting in neurological deficits, including fatal cases, have been reported in patients with SLE receiving immunosuppressants, including BENLYSTA. Risk factors for PML include treatment with immunosuppressant therapies and impairment of immune function. Consider the diagnosis of PML in any patient presenting with new-onset or deteriorating neurological signs and symptoms and consult with a neurologist or other appropriate specialist as clinically indicated. In patients with confirmed PML, consider stopping immunosuppressant therapy, including BENLYSTA. HYPERSENSITIVITY REACTIONS (INCLUDING ANAPHYLAXIS) Acute hypersensitivity reactions, including anaphylaxis and death, have been reported in association with BENLYSTA. These events generally occurred within hours of the infusion; however, they may occur later. Non-acute hypersensitivity reactions including rash, nausea, fatigue, myalgia, headache, and facial edema have been reported and typically occurred up to a week following the most recent infusion. Hypersensitivity, including serious reactions, has occurred in patients who have previously tolerated infusions of BENLYSTA. Limited data suggest that patients with a history of multiple drug allergies or significant hypersensitivity may be at increased risk. In the controlled clinical trials of BENLYSTA administered intravenously, hypersensitivity reactions occurring on the day of the infusion were reported in 13% (191/1,458) and 11% (76/675) of patients receiving BENLYSTA and placebo, respectively. Anaphylaxis was observed in 0.6% (9/1,458) and 0.4% (3/675) of patients receiving BENLYSTA and placebo, respectively. Manifestations included hypotension, angioedema, urticaria or other rash, pruritus, and dyspnea. Some patients (13%) received premedication, which may have mitigated or masked a hypersensitivity response. There is insufficient evidence to determine whether premedication diminishes the frequency or severity of these reactions. Healthcare providers should be aware of the risk of hypersensitivity reactions and be prepared to manage anaphylaxis. In the event of a serious hypersensitivity reaction, discontinue BENLYSTA immediately and administer appropriate medical therapy. Patients should be monitored during and for an appropriate period of time after the intravenous administration of BENLYSTA. Patients receiving BENLYSTA should be informed of the signs and symptoms of an acute hypersensitivity reaction, and be instructed to seek immediate medical care should a reaction occur. In the controlled trial of BENLYSTA administered subcutaneously (N = 836), the incidence and severity of systemic hypersensitivity reactions were similar to those observed in the intravenous clinical trials. INFUSION REACTIONS In the controlled clinical trials, infusion reactions occurring on the day of the infusion were reported in 17% (251/1,458) and 15% (99/675) of patients receiving BENLYSTA and placebo, respectively. Serious infusion reactions (excluding hypersensitivity reactions) were reported in 0.5% and 0.4% of patients receiving BENLYSTA and placebo, respectively. Serious infusion reactions included bradycardia, myalgia, headache, rash, urticaria, and hypotension. The most common infusion reactions occurring in ≥3% of patients receiving BENLYSTA were headache, nausea, and skin reactions. Some patients (13%) received premedication, which may have mitigated or masked an infusion reaction; however, there is insufficient evidence to determine whether premedication diminishes the frequency or severity of these reactions. BENLYSTA should be administered by healthcare providers prepared to manage infusion reactions. The infusion rate may be slowed or interrupted if the patient develops an infusion reaction. Healthcare providers should be aware of the risk of hypersensitivity reactions, which may present as infusion reactions, and monitor patients closely. DEPRESSION In controlled clinical trials of BENLYSTA administered intravenously, serious psychiatric events were reported in 0.8% and 0.4% of patients receiving BENLYSTA and placebo, respectively. Serious depression was reported in 0.4% and 0.1% of patients receiving BENLYSTA and placebo, respectively. Two suicides were reported in patients receiving BENLYSTA. In the controlled trial of BENLYSTA administered subcutaneously, serious psychiatric events were reported in 0.2% of patients receiving BENLYSTA and in no patients receiving placebo. It is unknown if treatment with BENLYSTA is associated with increased risk for these events. Instruct patients to contact their healthcare provider if they experience new or worsening depression, suicidal thoughts, or other mood changes. MALIGNANCY The impact of treatment with BENLYSTA on the development of malignancies is not known. The mechanism of action of BENLYSTA could increase the risk for the development of malignancies. IMMUNIZATION Live vaccines should not be given for 30 days before or concurrently with BENLYSTA. BENLYSTA may interfere with the response to immunizations. USE WITH BIOLOGIC THERAPIES OR IV CYCLOPHOSPHAMIDE BENLYSTA has not been studied in combination with other biologic therapies, including B-cell targeted therapies, or IV cyclophosphamide. Therefore, use of BENLYSTA is not recommended in combination with these therapies. ADVERSE REACTIONS Intravenous administration Adverse reactions, regardless of causality, occurring in at least 3% of patients with SLE who received BENLYSTA 10 mg/kg and placebo respectively and, at an incidence at least 1% greater than that observed with placebo in the 3 controlled studies, were: nausea 15% and 12%; diarrhea 12% and 9%; pyrexia 10% and 8%; nasopharyngitis 9% and 7%; bronchitis 9% and 5%; insomnia 7% and 5%; pain in extremity 6% and 4%; depression 5% and 4%; migraine 5% and 4%; pharyngitis 5% and 3%; cystitis 4% and 3%; leukopenia 4% and 2%; viral gastroenteritis 3% and 1%. Subcutaneous administration The safety profile observed for BENLYSTA administered subcutaneously was consistent with the known safety profile of BENLYSTA administered intravenously, with the exception of local injection site reactions, which occurred in 6.1% and 2.5% of patients receiving BENLYSTA and placebo, respectively. OTHER IMPORTANT INFORMATION FOR BENLYSTA USE IN SPECIFIC POPULATIONS Pregnancy: There are insufficient data on use of BENLYSTA in pregnant women to establish whether there is drug-associated risk for major birth defects or miscarriage. Following an assessment of benefit versus risk, if prevention is warranted, women of childbearing potential should use effective contraception during treatment and for at least 4 months after the final treatment. Lactation: There is no information available on the presence of belimumab in human milk, the effects on the breastfed infant, or the effects on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for BENLYSTA and any potential adverse effects on the breastfed child from BENLYSTA or from the underlying maternal condition. Black/African American Patients: In controlled clinical trials of BENLYSTA administered intravenously, SLE Responder Index-4 (SRI-4) response rates were lower for black/African American patients receiving BENLYSTA relative to black/African American patients receiving placebo. In the controlled trial of BENLYSTA administered subcutaneously, SRI-4 response was slightly higher for black/African American patients receiving BENLYSTA relative to black/African American patients receiving placebo, but the treatment difference was not as great as that observed in the overall population. Use with caution in black/African American patients. Populations not studied Benlysta has not been studied in the following patient groups, and is not recommended in patients with: ∙ severe active central nervous system lupus ∙ severe active lupus nephritis ∙ HIV ∙ a history of, or current, hepatitis B or C ∙ hypogammaglobulinaemia (IgG <400 mg/dl) or IgA deficiency (IgA <10 mg/dl) ∙ a history of major organ transplant or hematopoietic stem /cell /marrow transplant or renal transplant.
  23. Researchers identify new genetic markers in patients with lupus Langefeld CD, et al. Nat Commun. 2017;doi:10.1038/ncomms16021. July 21, 2017 Among patients with lupus, researchers have identified new genetic markers that predispose patients to the disease, according to a recently published study. “This study is the largest multi-ethnic lupus genetics study to date and allowed us to identify many new genetic markers, some of which are specific to individual ethnic groups and others that are shared across ethnicities,” Carl Langefeld, PhD, lead author of the study and professor of biostatistical sciences at Wake Forest School of Medicine, said in a press release. “With this information, we can begin to better understand the differences in the rates and severity of disease across ethnic groups.” Researchers assessed 27,574 participants. They identified 58 distinct non-human leukocyte antigen regions in the Europeans, nine in the Africans and 16 in the Hispanic Americans. All of these included 24 new lupus regions. “In addition, we observed that many of the genetic markers associated with lupus are shared across numerous autoimmune diseases, and those that are not shared may allow us to understand why a person develops lupus instead of another autoimmune disease,” Langefeld said. “These results will help us identify the biological pathways that pharmaceutical companies may target, and ultimately, develop personalized medicine for the treatment of lupus.” Reference: www.wakehealth.edu/News-Releases/2017/Large_Multiethnic_Study_Identifies_Many_New_Genetic_Markers_for_Lupus.htm Large Multi-ethnic Study Identifies Many New Genetic Markers for Lupus WINSTON-SALEM, N.C. – July 17, 2017 – Scientists from an international consortium have identified a large number of new genetic markers that predispose individuals to lupus. The study is published in the July 17 issue of the journal Nature Communications and was led by researchers at Wake Forest Baptist Medical Center, Oklahoma Medical Research Foundation, King’s College of London and Genentech Inc. Autoimmune diseases strike one in 15 Americans, are among the top 10 causes of death in women and cost an estimated $100 billion a year in medical care. In autoimmune diseases, the body attacks itself. Systemic lupus erythematosus, the form of lupus studied here, is the most common type of lupus and is a prototypical autoimmune disease. Lupus strikes women nine times more often than men and its onset is most common during childbearing age. Also, African-American and Hispanic women are two to three times more likely to develop lupus and tend to have more severe cases than Caucasian women. At present, there is no cure for lupus, which can affect many parts of the body, including joints, skin, kidney, heart, lungs, blood vessels and brain, according to the Lupus Research Alliance. “This study is the largest multi-ethnic lupus genetics study to date and allowed us to identify many new genetic markers, some of which are specific to individual ethnic groups and others that are shared across ethnicities,” said Carl Langefeld, Ph.D., lead author of the study and professor of biostatistical sciences at Wake Forest School of Medicine, a part of Wake Forest Baptist. “With this information, we can begin to better understand the differences in the rates and severity of disease across ethnic groups. “In addition, we observed that many of the genetic markers associated with lupus are shared across numerous autoimmune diseases, and those that are not shared may allow us to understand why a person develops lupus instead of another autoimmune disease. These results will help us identify the biological pathways that pharmaceutical companies may target, and ultimately, develop personalized medicine for the treatment of lupus.” This study analyzed genetic data from 27,574 individuals of European, African American and Hispanic ancestry using the Immunochip, a genotyping technology designed specifically for autoimmune diseases. The researchers identified 58 regions of the genome in Caucasians, nine in African Americans and 16 in Hispanics. These regions appear independent of the well-known Human Leukocyte Antigen (HLA) associations, also studied in depth here. An important observation was that nearly 50 percent of these regions had multiple genetic variants that predispose someone to lupus, Langefeld said. Another key finding was that as the number of genetic risk variants (alleles) a person has increases, the risk for lupus increases more than expected if the variants were working independently. These observations led the authors to propose a “cumulative hits hypothesis for autoimmune disease”. In future research, the team hopes to better understand how these genetic variants influence the risk of lupus, identify any possible drug targets and determine if any environmental factors, such as infections, can trigger the development of the disease in someone who has a genetic susceptibility. They emphasize that it is important to increase the number of understudied populations, such as African-American and Hispanic, to better understand the genetic causes of health disparities in lupus and the unique risks in all ethnic groups. “We are delighted to see the work we funded on the ImmunoChip come to fruition and congratulate Dr. Langefeld along with his colleagues on this tremendous success," said Kenneth M. Farber, CEO and President, Lupus Research Alliance. "This study is among the few to concentrate heavily on non-Caucasian populations for a significantly broader evaluation, while utilizing the most current and comprehensive information about human DNA.” Key support for the study was provided by the Lupus Research Alliance and the National Institutes of Health.

  24. Speakers: Lupus remains challenging disease July 6, 2017 Healio Rheumatology recently interviewed Richard Furie, MD, from Hofstra Northwell School of Medicine, Lars Rönnblom, MD, from Uppsala University in Sweden, and Peggy K. Crow, MD, from Hospital for Special Surgery, about the future of lupus during the Interferon Summit. “We need better drugs,” Furie said. “There is a major need for safer and more efficacious therapies. The typical patient who gets this disease is a young woman and it can be devastating.” SEE ALSO Furie discusses advances in SLE treatment Through the Cracks: Niche Patient Population Battles... Elusive Target: A Rundown of the Drug Pipeline for Systemic... Richard Furie To illustrate the need for better therapies, Furie discussed the progression of treatments for the disease. “We have come a long way with treatments,” he said. “If you go back before steroids were developed, the mortality was high. It was probably 50% at 7 years, but steroids were introduced and they have been a major advance. Then, after that, it was the immunosuppressives; but, until we get rid of all mortality and morbidity, we need new drugs.” To derive better therapies for a disease, there needs to be better disease classification. Rönnblom talked about the current classification of lupus patients and how to treat the underlying cause vs. a cluster of symptoms. “We classify patients with an auto[body] or antibody profile,” Rönnblom said. “In lupus, we classify them according to organ manifestation, but also when they have this interferon signature. My guess is that we will see more pathways coming up. Much of this data will be generated by the clinical trials, of course, who responds and who does not respond.” Lars Rönnblom Crow said better understanding about the molecular pathway and underlying mechanisms of the disease can lead to better therapy. “My own speculation is that we will probably end up with combination therapies and maybe combinations will allow us to use lower doses, each of one or two or three therapies to avoid toxicity. For example, we might want to target this type 1 interferon pathway that I believe is active in a sustained way throughout the disease, but may be more important in some stages than others,” she said. Peggy K. Crow “To have a more effective therapeutic activity, we might also want to target activated T cells or B cell differentiation. My guess is that we, as a community, will end up trying different combinations and some of the selection of those might be informed by the molecular pathways that an individual shows to be activated or abnormal.” – by Will A.

  25. Glucocorticoids Use and Organ Damage in Lupus http://www.rheumatologynetwork.com/lupus/glucocorticoids-use-and-organ-damage-lupus Glucocorticoids exposure is strongly associated with the accrual of irreversible organ damage in systemic lupus erythematosus patients, independent of disease activity, researchers report. “Our findings suggest that only extremely low doses of glucocorticoid can be considered free of association with damage accrual in patients with SLE,” write researchers in the Nov. 22 issue of Lupus Science and Medicine Glucocorticoids are a mainstay treatment in both acute and chronic systemic lupus erythematosus. Previous studies have demonstrated that damage accrual is associated with cumulative disease activity. However, more recent studies suggest that damage accrual may also be associated with systemic lupus erythematosus treatment. Approximately 60 percent of systemic lupus erythematosus patients experience permanent organ damage within seven years of being diagnosed with the disease. Given that glucocorticoids are often used in the context of high disease activity, it has been challenging for researchers to tease out the independent effect of systemic lupus erythematosus treatment on damage accrual. This was an observational study of 162 systemic lupus erythematosus patients — 75 percent of whom received glucocorticoids. The patients were observed for two to 4.7 years by Diane Apostolopoulos, M.D., of Monash University in Australia, and colleagues. They measured damage accrual finding that glucocorticoid patients were 42 percent more likely to have significantly more damage as compared to patients who were not prescribed glucocorticoids (42% vs 15%, p<0.01). The observational nature of the study was one of the limitations of the study, yet, it is noteworthy, the researchers wrote. “Given the limitations of observational studies in the face of confounding by indication, our findings suggest the urgent need for a randomized study comparing the effect on damage accrual of usual care with that of a strategy that stringently limits glucocorticoid dosing,” Dr. Apostolopoulos and colleagues wrote. In an editorial that was published online April 7 in Lupus Science and Medicine, Maarten Boers, M.D., of VU University Medical Center in the Netherlands, conveys concerns of the medical community misinterpreting observational studies by limiting applications of a potentially life-saving treatment. “The truth of the matter is that trials on glucocorticoid beneficial and adverse effects are not being done, and that observational studies (invariably only focusing on glucocorticoid adverse effects, both related and unrelated to the disease) are hopelessly and irretrievably confounded by indication,” wrote Boers. “In brief, patients with the most severe disease are preferentially treated with glucocorticoids, and this leads to the associations found in observational studies, regardless of the beneficial effects of glucocorticoids.” The study Glucocorticoid use is associated with harm in both domains of the (Systemic Lupus International Collaborating Clinics Damage Index (SDI) traditionally associated with glucocorticoid-induced harm (cataracts, osteoporotic fracture, avascular necrosis, diabetes mellitus) and the residual SDI domains not previously associated with glucocorticoid-induced harm. Even lower doses of glucocorticoid are associated with damage accrual in SLE. The threshold identified was a time-adjusted mean prednisolone of 4.4 mg per day. Cumulative prednisolone exposure was associated with overall damage accrual after controlling for ethnicity and disease activity and was significant at time-adjusted mean doses above 4.42 mg prednisolone per day. A dose-response relationship between cumulative prednisolone use and irreversible organ damage accrual was observed, with increasing odds ratios with each ascending quartile. Compared to patients in the lowest quartile, patients in the highest quartile of cumulative prednisolone had adjusted odds ratio of 13.46, 95 percent CI (3.59 to 50.4), p<0.01 for damage accrual. Of the demographic factors evaluated, only ethnicity was associated with damage accrual. Asian patients had reduced odds of damage accrual compared with Caucasians (adjusted OR=0.22, 95% CI (0.09 to 0.53), p<0.01). “Our findings further emphasize the need for new, more effective treatments for SLE that minimize or eliminate the need for glucocorticoids,” wrote Apostolopoulos and team.
