European Journal of Rheumatology (Eur J Rheumatol) is an international, open access peer reviewed journal committed to promoting the highest standards of scientific exchange and education. The journal is published quarterly on January, April, July and October. The aim of the European Journal of Rheumatology is to cover various aspects of rheumatology for its readers, encompassing the spectrum of diseases with arthritis, musculoskeletal conditions, autoinflammatory diseases, connective tissue disorders, osteoporosis, translational research, the latest therapies and treatment programs. European Journal of Rheumatology publishes original articles, invited reviews, case based reviews, letters to the editor and images in rheumatology. The publication language of the journal is English. Accepted manuscripts are copy-edited for grammar, punctuation, and format. Once the publication process of a manuscript is completed, it is published online on the journal's webpage as an aheadof-print publication before it is included in its scheduled issue. A PDF proof of the accepted manuscript is sent to the corresponding author and their publication approval is requested within 2 days of their receipt of the proof.
Background Systemic lupus erythematosus (SLE) is an autoimmune multisystemic disease with a wide variety of clinical manifestations. One of its symptoms, associated to high morbidity, is serositis. Its prevalence ranges between 11% and 54%, and little is known about factors associated to this manifestation. The aim of this study is to determine the prevalence of serositis in SLE patients visited at the outpatient Lupus Unit of the Hospital del Mar and identify risk factors that can be used as predictors of this manifestation. Methods A retrospective case-control study was performed based on the review of 297 medical records of SLE patients. Twenty-eight patients were identified to have suffered serositis (cases) and were age- and sex-matched with 2 controls with SLE without serositis. Results The overall prevalence of serositis in our cohort was 9.42%, being higher in men than in women, 30% versus 7.9% ( p = 0.001, 95% CI: 1.7–42.4%). In 40.7%, it was the first manifestation of the disease. When looking for serositis-associated factors, an association was found with anti-dsDNA antibodies measured by the Crithidia method ( p = 0.016), and different measures of corticosteroids, where cases had required higher maximum doses and more pulses than controls throughout the disease, although this last correlation was lost when adjusting for confounding variables as nephritis and arthritis. Cases also received more mycophenolic acid ( p = 0.021) and, marginally, more belimumab ( p = 0.056). Conclusion The overall prevalence of serositis was 9.42%, being significantly higher in men (30%). Therefore, male gender constitutes a risk factor for serositis, and almost one third of men will develop this manifestation, so greater awareness is required in SLE men. CrithidiaDNA+ was also identified as a risk factor, and it should be determined in all SLE patients. Cases significantly received more corticosteroid pulses and higher maximum doses in relation to other SLE severe manifestations, which could imply a more aggressive form of SLE in patients with serositis.
ObjectivesLupus nephritis (LN) requires renal replacement therapy in 10%–30% of patients. About 30% of these patients receive a kidney transplant. Belatacept is a second-generation, selective, T-cell co-stimulator blocker (inhibits cytotoxic, T-lymphocyte antigen 4, CTLA-4) used as an alternative to calcineurin inhibitors (CNI) for maintenance regimens after kidney transplantation. The pathogenic relevance of CTLA-4 inhibition and the favourable cardiovascular profile of belatacept make it an attractive therapeutic option in systemic lupus erythematosus (SLE). Intravenous administration of belatacept ensures therapeutic adherence.MethodsThis retrospective, single-centre study evaluates the outcomes of LN kidney transplant recipients treated with belatacept for reasons not related to SLE at the Columbia University Lupus and Renal Transplant Cohort.ResultsBelatacept was started in six patients on CNI regimens at 15.5±17.1 months following transplantation for LN. In five patients, creatinine levels stabilised 6 months after belatacept, one returned to haemodialysis due to CNI toxicity and pyelonephritis and one relisted for a kidney transplant following acute cellular rejection and cortical necrosis. Five patients are followed for extrarenal lupus; no extrarenal manifestations were documented in the other two patients. Data on SLE disease activity pre-belatacept and post-belatacept were available and scored in three patients using the SLE Disease Activity Index Glucocorticosteroid Index (SLEDAI-2KG), which accounts for clinical and laboratory manifestations, as well as steroid dose. Mean SLEDAI-2KG decreased from 13 to 7.6.ConclusionBelatacept in LN kidney transplant recipients may decrease extrarenal manifestations, attenuate CNI toxicity and stabilise allograft function, providing a better alternative to CNI regimens. Furthermore, these data suggest that belatacept, although initiated for reasons not related to SLE, might have a beneficial effect in SLE.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
