In patients with FM we found increases over time in serum levels and/or PBMC-stimulated activity of soluble factors whose release is stimulated by substance P. Because IL-8 promotes sympathetic pain and IL-6 induces hyperalgesia, fatigue and depression, it is hypothesized that they may play a role in modulating FM symptoms.

Objectives Osteoarthritis (OA) of the knee is a major cause of pain and limited function in older adults. Longer-term studies of medical therapy of OA are uncommon. This study was undertaken to evaluate the efficacy and safety of glucosamine and chondroitin sulfate (CS), alone or in combination, as well as celecoxib and placebo on painful knee OA over 24 months. Methods A 24-month, double-blind, placebo controlled study, conducted at 9 sites in the United States ancillary to the Glucosamine/Chondroitin Arthritis Intervention Trial (GAIT), enrolled 662 patients with knee OA who satisfied radiographic criteria (Kellgren/ Lawrence [K/L] grade 2 or grade 3 changes and JSW of at least 2 mm at baseline). Patients who had been randomized to 1 of the 5 groups in GAIT continued to receive glucosamine 500 mg 3 times daily, CS 400 mg 3 times daily, the combination of glucosamine and CS, celecoxib 200 mg daily, or placebo over 24 months. The primary outcome measure was the number who reached a 20% reduction in WOMAC pain over 24 months. Secondary outcomes included reaching an OMERACT/OARSI response and change from baseline in WOMAC pain and function. Results The odds of achieving a 20%WOMAC were 1.21 for celecoxib, 1.16 for glucosamine, 0.83 for glucosamine and chondroitin sulfate and 0.69 for chondroitin sulfate alone with widely overlapping confidence intervals for all treatments. Conclusions Over 2 years, no treatment achieved a clinically important difference in WOMAC Pain or Function as compared with placebo. However, glucosamine and celecoxib showed beneficial trends. Adverse reactions were not meaningfully different among treatment groups and serious adverse events were rare for all therapies.

Troglitazone monotherapy decreased fasting and postprandial glucose levels in patients with type 2 diabetes, primarily by augmenting insulin-mediated glucose disposal.

Objective. Osteoarthritis (OA) of the knee causes significant morbidity and current medical treatment is limited to symptom relief, while therapies able to slow structural damage remain elusive. This study was undertaken to evaluate the effect of glucosamine and chondroitin sulfate (CS), alone or in combination, as well as celecoxib and placebo on progressive loss of joint space width (JSW) in patients with knee OA.
