Chemokines play an essential role in the progression of rheumatoid arthritis (RA). In the present study we examined the expression and regulatory mechanisms of IFN-gamma inducible protein (IP)-10 in RA synovitis. RA synovial fluid contained greater amounts of IP-10 than did synovial fluid from patients with osteoarthritis. Immunolocalization analysis(More)
Polymorphonuclear neutrophils (PMNs) are usually thought of as the leukocyte population involved in acute inflammatory responses, acting as a first line of defense against invading microorganisms. These terminally differentiated cells are generally not thought of as an important source of de novo synthesis of polypeptide mediators. Recent progress has(More)
A disintegrin and metalloproteases (ADAMs) are a family of proteins that have been reported to be involved in several inflammatory conditions. We examined the secretion of ADAM-10 in biological fluids from patients with rheumatoid arthritis (RA) and the role it plays in monocyte migration. ADAM-10 levels were measured using enzyme-linked immunosorbent(More)
OBJECTIVE To investigate the clinical features of patients with dermatomyositis (DM) complicated by hemophagocytic syndrome (HPS). METHODS Twenty-four patients diagnosed with DM and treated at our hospital between January 2002 and April 2007 were enrolled for study. Serum levels of various parameters including cytokines were determined during the active(More)
To investigate the characteristics of patients with adult-onset Still's disease (AOSD), serum cytokines and chemokines were measured to examine their associations with systemic manifestations of AOSD, especially hemophagocytic syndrome (HPS). Nineteen patients diagnosed with AOSD were enrolled. Serial serum samples were obtained from patients with AOSD in(More)
OBJECTIVE To examine the relation between serum chemokine levels and patient responsiveness to infliximab, and the influence of infliximab administration on serum chemokine levels. METHODS Serum levels of the chemokines CX3CL1, CXCL8, CCL3, and CXCL10 were quantified prior to (at baseline) and after 30 weeks of treatment with infliximab in 20 patients(More)
PURPOSE Depression in rheumatoid arthritis (RA) patients is more severe than in healthy people. Herein, we report improved depression in RA patients using biologic agents. We examined whether depression was improved by tacrolimus combination therapy when biologic agents were ineffective. METHOD The study included 13 RA patients who used biologic agents.(More)
OBJECTIVES The study investigated whether renal complications affected the efficacy and safety of tacrolimus combination therapy in patients with systemic lupus erythematosus (SLE) during a maintenance phase. METHODS Fifty-seven patients with SLE (A: 30 cases with renal complication, B: 27 cases without renal complications) were included. The presence of(More)
We evaluated the occurrence of cytomegalovirus (CMV) infection and the background characteristics in twenty-three hospitalized patients with inflammatory connective tissue diseases including systemic lupus erythematosus, polymyositis/dermatomyositis, rheumatoid vasculitis, microscopic polyangitis, and Takayasu's arteritis. Cytomegalovirus antigenemia was(More)
The characteristics of Pneumocystis carinii pneumonia (PCP) in patients with connective tissue diseases (CTDs) were examined retrospectively. Nine patients were enrolled in this study. Their mean age was 57.1 years. All the patients received a high-dose steroid or immunosuppressant. The onset (mean 6.6 days) of fever, cough, breathlessness, and geographical(More)
