The short-term role of corticosteroid therapy for pulmonary arterial hypertension associated with connective tissue diseases: report of five cases and a literature review.
Pulmonary arterial hypertension (PAH) is a life-threatening complication in connective tissue diseases (CTD). It remains controversial whether immunosuppressive therapy is useful for PAH associated with CTD (PAH-CTD). The Dana Point algorithm does not refer such treatments in patients with PAH-CTD due to the lack of evidence. ⋯ Two patients required dose increase or additional administration of vasodilators due to the dose reduction of PSL. Corticosteroid therapy may be effective for PAH-CTD at least in the short term, even in low general activity of CTD or moderate PAH. Our experience suggests that corticosteroid therapy, by itself or in conjunction with standard vasodilators, is effective for PAH-CTD patients.

Cutaneous lupus erythematosus (CLE) is characterized by enhanced interferon α (IFNα) levels in serum and in tissue. Since IFNα promotes a Th1-biased immune response, we hypothesized that a Th1-associated chemokine receptor profile should be a typical finding in patients with active CLE. Therefore, peripheral blood mononuclear cells were isolated from patients with different CLE subsets (n = 15), healthy controls (n = 13) and patients under immunotherapy with IFNα (n = 7). ⋯ The enhanced CCR5/CCR3 ratio closely correlated with the MxA levels in peripheral lymphocytes and with disease activity. Our analyses revealed that active CLE is associated with a systemic type I IFN effect that appears to induce a shift towards a Th1-associated chemokine receptor profile. The CCR5/CCR3 T-helper cell ratio might therefore represent an indirect marker for the disease activity in CLE.

Fibromyalgia (FM) is a syndrome that can be associated with several rheumatic diseases. However, no study has evaluated its frequency in patients with primary antiphospholipid syndrome (PAPS). The objective of this study was to analyze the frequency of FM in PAPS patients compared with healthy controls, to determine the possible associations between FM and PAPS features, and also to evaluate quality of life and depression in these patients. ⋯ Analysis of PAPS patients with FM compared with those subjects without FM revealed no significant differences regarding demographic features or thrombotic or clinical events; however, PAPS patients who also had FM had lower values in SF-36 dimensions as well as higher FIQ (82.6 ± 9.6 vs. 33.6 ± 29.8, respectively, p < 0.0001) and VAS scores (6.6 ± 2.97 vs. 3.25 ± 3.11, respectively, p = 0.03). BDI scores, in contrast, were similar in both groups. In conclusion, one-fifth of PAPS patients had fibromyalgia and a low quality of life when compared with healthy subjects.
