Jr. Odell et al., TREATMENT OF EARLY RHEUMATOID-ARTHRITIS WITH MINOCYCLINE OR PLACEBO -RESULTS OF A RANDOMIZED, DOUBLE-BLIND, PLACEBO-CONTROLLED TRIAL, Arthritis and rheumatism, 40(5), 1997, pp. 842-848
Objective. To determine if minocgcline is an effective therapy for ser
opositire rheumatoid arthritis (RA) when used within the first year of
disease. Methods. The Rheumatoid Arthritis Investigational Network en
rolled 36 patients with RA of <1 year duration into a 6-month study of
minocycline (100 mg twice daily) versus placebo, All patients were rh
eumatoid factor positive. The primary end point of the study was succe
ssful completion of 6 months of treatment with no drug toxicity while
maintaining 50% improvement in composite symptoms of arthritis. Result
s. Eighteen of the 16 patients who were enrolled met 50% improvement c
riteria at 3 months, and maintained at least a 50% improvement for 6 m
onths with no significant drug toxicity, Among them were 15 of the 23
patients (65%) treated with minocycline and 3 of 23 patients (13%) tre
ated with placebo (P <0.001). Conclusion. In patients with early serop
ositive RA, therapy with minocycline is superior to placebo.
