Hydroxychloroquine demonstrates moderate efficacy in treating rheumatoid arthritis (RA) with a favorable safety profile. This antimalarial drug offers significant benefits for RA patients compared to placebo, with low toxicity.

Area of Science:

  • Rheumatology
  • Pharmacology
  • Clinical Trials

Background:

  • Rheumatoid arthritis (RA) is a chronic autoimmune disease requiring effective treatment options.
  • Antimalarials have been explored for their anti-inflammatory properties in managing RA.

Purpose of the Study:

  • To evaluate the short-term efficacy and toxicity of antimalarials for rheumatoid arthritis treatment.
  • To synthesize evidence from randomized controlled trials (RCTs) and controlled clinical trials (CCTs).

Main Methods:

  • Systematic search of multiple databases (Cochrane, Medline, Embase) up to July 1997.
  • Inclusion of RCTs and CCTs comparing antimalarials (specifically hydroxychloroquine) against placebo in RA patients.
  • Independent data abstraction and quality assessment using Jadad's scale; pooled analysis of outcome measures and toxicity.

Main Results:

  • Four trials involving 300 patients on hydroxychloroquine and 292 on placebo were analyzed.
  • Hydroxychloroquine showed statistically significant benefits in RA outcome measures (joint counts, pain, global assessments) compared to placebo.
  • No significant difference in withdrawals due to toxicity was observed between hydroxychloroquine and placebo groups.

Conclusions:

  • Hydroxychloroquine is an efficacious treatment for rheumatoid arthritis.
  • The drug offers a moderate overall effect with a low toxicity profile, making it a valuable option for RA management.
