The aim of this study was to assess the association between Raynaud's phenomenon (RP) and specific capillaroscopic findings in patients with SLE and particular clinical manifestations of the disease. A total of 79 patients with SLE were included in the study: 44 of them (43 women) with RP and 35 (32 women) age-, sex-, and disease- duration-matched patients with SLE without RP. Demographic variables, clinical manifestations, laboratory and nailfold capillaroscopy findings were compared between the two groups. Central nervous systemic involvements (P = 0.0038) and peripheral neuropathy (P = 0.0336) were significantly more common in SLE patients with RP, while secondary Sjögren's syndrome (P = 0.0363) was more common in SLE patients without RP. RP occurred in 52 % of patients before SLE onset while 48 % of patients developed RP after they had been diagnosed with SLE. Arthritis/arthralgia (P = 0.0073) was significantly more common in patients who had been diagnosed with RP before the onset of SLE, while mucosal ulcers were more common in patients who contracted RP after the onset of SLE (P = 0.0258). Enlarged capillaries (P = 0.0482), presence of avascular areas (P = 0.0476), capillary hemorrhages (P = 0.0482), and granular blood flow (P = 0.0482) were more common in patients with SLE who also suffered from RP, than in patients with SLE without RP. The frequency of normal (63.6 vs. 82.9 %, P = 0.100) and nonspecific (25 vs. 17.1 %, P = 0.5696) capillaroscopy findings were similar in either groups. Scleroderma-like pattern of capillaroscopy finding was only found in patients with RP [(11.4 %), P = 0.0482]. RP in our patients with SLE was associated with specific clinical manifestations, indicating that prognostic relevance of RP in SLE should be evaluated. © Springer-Verlag 2012.

Objective. To evaluate the effect of a tumor necrosis factor-α (TNF-α) inhibitor (etanercept) on innate inflammatory and Th17 cytokines in patients with rheumatoid arthritis (RA). Methods. Serum samples were collected from 40 patients with active RA refractory to conventional disease-modifying antirheumatic drugs who initiated therapy with etanercept plus methotrexate (MTX). Treatment response was assessed at Week 24 according to the European League Against Rheumatism response criteria. Serum levels of interleukin 6 (IL-6), TNF-α, IL-32, IL-23, IL-17A, IL-21, and IL-22 were measured in patients with RA and 25 healthy controls. Results. Patients with RA had increased levels of IL-6 (p < 0.001), IL-32 (p < 0.001), IL-23 (p < 0.001), and a trend toward increased IL-21 in the sera compared to controls. At 24 weeks' posttreatment, followup serum samples of etanercept responders had decreased levels of IL-6 (p < 0.001) and increased IL-21 (p < 0.05) and IL-32 (p < 0.001), while there were no differences in cytokine levels in non-responders. Serum IL-6 levels were positively correlated with levels of erythrocyte sedimentation rate (r = 0.458, p < 0.01), C-reactive protein (r = 0.593, p < 0.01), and 28-joint Disease Activity Score (r = 0.432, p < 0.01) at baseline. Serum IL-21 levels were positively correlated with levels of rheumatoid factor (r = 0.513, r = 0.633, both p < 0.01) and antimutated citrullinated vimentin antibodies (r = 0.515, p < 0.01; r = 0.428, p < 0.05) at baseline and after 24 weeks of treatment with etanercept. Conclusion. Multiple inflammatory pathways contribute to persistent chronic inflammation in RA. In contrast to nonresponders, etanercept therapy modulated serum cytokine levels and caused a marked decrease of IL-6 levels in responders. IL-21 might be involved in the regulation of autoantibody production in RA. The Journal of Rheumatology Copyright © 2012. All rights reserved.
