  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. 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.
