Decreased microRNA-142-3p/5p expression causes CD4+ T cell activation and B cell hyperstimulation in systemic lupus erythematosus.
To examine the role of microRNA-142-3p/5p (miR-142-3p/5p) in the development of autoimmunity in patients with systemic lupus erythematosus (SLE). ⋯ The results of this study indicate that reduced expression of miR-142-3p/5p in the CD4+ T cells of patients with SLE causes T cell activity and B cell hyperstimulation.

Comparative StudyPerioperative all-cause mortality and cardiovascular events in patients with rheumatoid arthritis: comparison with unaffected controls and persons with diabetes mellitus.
Rheumatoid arthritis (RA) is associated with an increased cardiovascular (CV) burden similar to that of diabetes mellitus (DM). This risk may warrant preoperative CV assessment as is performed for patients with DM. We aimed to determine whether the risks of perioperative death and CV events among patients with RA differed from those among unaffected controls and patients with DM. ⋯ RA was not associated with adverse perioperative CV risk or mortality risk, which suggests that current perioperative clinical care does not need to be changed in this regard.

Case ReportsBrief report: induction of sustained remission in recurrent catastrophic antiphospholipid syndrome via inhibition of terminal complement with eculizumab.
Catastrophic antiphospholipid syndrome (CAPS) is characterized by histopathologic evidence of small vessel thrombosis, dysfunction of multiple organs occurring over a short period of time, and laboratory confirmation of the presence of antiphospholipid antibodies (aPL). Treatment of CAPS focuses on anticoagulation therapy and on removal of aPL that promote thrombosis by activating endothelial cells, monocytes, and platelets. Studies in animal models support the hypothesis that a more targeted intervention, such as complement inhibition, may be an effective means to prevent aPL-induced thrombosis. Herein we describe use of an inhibitor of complement activation to treat CAPS that was refractory to conventional therapy. ⋯ This first report of the use and clinical efficacy of eculizumab, an inhibitor of complement activation, in the treatment of CAPS demonstrates both the importance of complement (specifically, terminal complement components) in the pathogenesis of CAPS and the therapeutic benefit of complement inactivation.

Association of industry funding with the outcome and quality of randomized controlled trials of drug therapy for rheumatoid arthritis.
To assess the association of industry funding with the characteristics, outcome, and reported quality of randomized controlled trials (RCTs) of drug therapy for rheumatoid arthritis (RA). ⋯ Industry funding was not associated with a higher likelihood of positive outcomes of published RCTs of drug therapy for RA, and industry-funded RCTs performed significantly better than non-industry-funded RCTs in terms of reporting the use of some key methodologic quality measures.
