Review Meta AnalysisRisk of ischemic stroke in patients with systemic sclerosis: A systematic review and meta-analysis.
Several chronic inflammatory disorders, such as rheumatoid arthritis and idiopathic inflammatory myositis, have been shown to increase risk of ischemic stroke but the data on systemic sclerosis (SSc) remains unclear. ⋯ Our study demonstrated a statistically significant increased ischemic stroke risk among patients with SSc.

ReviewJAK inhibitor tofacitinib for treating rheumatoid arthritis: from basic to clinical.
Rheumatoid arthritis (RA) is a representative autoimmune disease characterized by chronic and destructive inflammatory synovitis. The multiple cytokines play pivotal roles in RA pathogenesis by inducing intracellular signaling, and members of the Janus kinase (JAK) family are essential for such signal transduction. An orally available JAK3 inhibitor, tofacitinib, has been applied for RA, with satisfactory effects and acceptable safety in multiple clinical examinations. ⋯ The common adverse events were infections, such as nasopharyngitis; increases in cholesterol, transaminase, and creatinine; and decreases in neutrophil counts. Although the mode of action of tofacitinib remains unclear, we clarified that the inhibitory effects of tofacitinib could be mediated through suppression of interleukin (IL)-17 and interferon (IFN)-γ production and proliferation of CD4(+) T cells in the inflamed synovium. Taken together, an orally available kinase inhibitor tofacitinib targeting JAK-mediated signals would be expected to be a new option for RA treatment.

Review Case ReportsPeriodic fever and erythema nodosum associated with MDS with trisomy 8: report of two cases and review of the literature.
We report two cases of myelodysplastic syndrome (MDS) with trisomy 8 who had periodic fever and erythema nodosum (EN). A 74-year-old man showed periodic fever and EN. A diagnosis of MDS with trisomy 8 was made, and he was successfully treated with prednisolone (PSL). ⋯ Marrow aspiration showed MDS with the chromosomal abnormality trisomy 8. He was successfully treated with PSL without repeated transient fever and elevation of creatine kinase. The results of a literature review of 35 cases of MDS with trisomy 8 and Behçet's disease-like symptoms, such as EN, oral ulcer and intestinal ulcer, suggest that the disease entity of "trisomy 8 syndrome" may be considered, and that it is an important differential diagnosis of periodic fever and EN.

Review Case ReportsPulmonary-renal syndrome in systemic sclerosis: a report of three cases and review of the literature.
We describe three cases of acute renal failure with diffuse alveolar hemorrhage, which is designated pulmonary-renal syndrome (PRS), in systemic sclerosis (SSc) and review the literature to better define this rare but severe complication of SSc. The clinical course of three SSc patients with acute renal failure and concomitant diffuse alveolar hemorrhage are reported, and the literature published between 1967 and 2005 is reviewed following a PubMed search. Including our cases, a total of 19 SSc patients with acute renal failure and concomitant diffuse alveolar hemorrhage have been reported. ⋯ Pulmonary-renal syndrome is a fatal complication of SSc and results from different pathogenic processes. Prompt differential diagnosis between the subsets is critical, because therapeutic strategy may differ in the use of high-dose corticosteroid and plasma exchange between the subsets of PRS. Clinical courses of the patients with PRS with thrombotic microangiopathy suggest that high-dose corticosteroid therapy is a trigger of diffuse alveolar hemorrhage in patients with diffuse SSc with signs of thrombotic microangiopathy.

Review Case ReportsPneumocystis jiroveci pneumonia associated with low-dose methotrexate treatment for rheumatoid arthritis: report of two cases and review of the literature.
Low-dose methotrexate (MTX) therapy is widely used for rheumatoid arthritis (RA) because of its favorable efficacy and toxicity profile. Although Pneumocystis jiroveci pneumonia (PCP) is most often seen in severely immunosuppressed patients, PCP complicating low-dose MTX therapy for RA has been reported to sometimes occur. We herein report two cases of patients who developed PCP during treatment with low-dose MTX, and discuss the importance of prophylaxis for this opportunistic infection.
