OBJECTIVE: T cells are involved in the pathogenesis of rheumatoid arthritis (RA). In animal models of autoimmune diseases, blockade of costimulatory molecules on antigen-presenting cells has been demonstrated to be effective in preventing or treating this disease by preventing T cell activation. To date, the effect of costimulatory blockade in patients with RA is unknown. The goal of this multicenter, multinational study was to determine the safety and preliminary efficacy of ...

OBJECTIVE: To study the relationship of spinal inflammation and fatty degeneration (FD) as detected by MRI and new bone formation seen on conventional radiographs (CRs) in ankylosing spondylitis (AS).

METHODS: CRs at baseline, 2 years and 5 years and spinal MRIs at baseline and 2 years of 73 AS patients treated with infliximab in European AS Infliximab Cohort were available. Relative risks (RR) were calculated with a general linear model after adjustment for within-patient ...

Abstract. Although fluoride salts have been shown to be capable of linearly increasing spinal bone mineral density (BMD) in postmenopausal osteoporosis, the effects of this gain in density on the vertebral fracture rate remain controversial. We conducted a 2-year multicenter, prospective, randomized, double-masked clinical trial in 354 osteoporotic women with vertebral fractures (mean age 65.7 years). They received either fluoride (208 patients), given as sodium fluoride (50 mg/day) or ...

Mycophenolate mofetil (MMF) is a new immunosuppressive agent currently used in organ transplantation and under evaluation in immune-mediated inflammatory disorders such as rheumatoid arthritis. Although MMF was shown to inhibit purine nucleotide synthesis in lymphocytes, it is still unclear whether it might also exert direct antiinflammatory actions in vivo. To address this question, we evaluated the effects of MMF administration on the responses of mice to a single challenge with ...

OBJECTIVES: We compare the symptomatic effects of 300 or 600mg daily of ASU in patients with knee osteoarthritis.

METHODS: A multicenter, double blind, study comparing a daily intake of 300mg or 600mg of ASU and placebo. The study lasted 3 months and involved patients of both genders, aged 45 to 80 years and presenting with femoro-tibial knee osteoarthritis. The primary endpoint was NSAIDs and analgesics intake between D30 and D90.

RESULTS: All efficacy parameters were significantly ...

Various proteases are expressed in the minor salivary glands (MSG) of patients with Sjögren's syndrome (SS), and as we have already shown, prolactin is neosynthesized in the acinar cells of patients with SS. The present study aims to characterize the influence of PRL on the expression of cathepsin B and D in the MSG of patients with SS. Cathepsin B and D expression was investigated immunohistochemically in MSG of 30 patients with SS and 15 healthy volunteers. The presence of cathepsin B ...

OBJECTIVE: Tumor necrosis factor alpha (TNFalpha) is a proinflammatory cytokine involved in the pathogenesis of Sjögren's syndrome (SS), and blockade of TNFalpha may reduce the activity of the disease. The purpose of this study was to evaluate the safety and potential efficacy of infliximab, a chimeric human-mouse anti-TNFalpha monoclonal antibody, in patients with active primary SS.

METHODS: This was a single-center, open-label pilot study. Sixteen patients with active primary SS ...

In this randomized, double-blind, double-dummy trial, 113 patients with acute sciatica were treated with a single 15-mg dose of meloxicam given intramuscularly (n = 54) or orally (n = 59). There was a significant improvement in induced pain (as measured by using the straight-leg-raising test) in both treatment groups at 60 minutes (P < 0.005), and there was a significant difference in favor of the intramuscular formulation in terms of the time to maximum improvement of induced pain (P = ...
