A single-blind comparative study of auranofin and hydroxychloroquine in patients with rheumatoid arthritis.
Forty patients with rheumatoid arthritis were randomly allocated to treatment with auranofin 3 mg b.d. or hydroxychloroquine 200 mg b.d. Twenty patients received each drug. Efficacy was analysed by comparing patients with available data at weeks 12, 24, 36 and 48 with baseline within each treatment group, and between treatment groups at each of these same time points. There were statistically significant improvements in all measured parameters of clinical efficacy among hydroxychloroquine treated patients, and in all efficacy parameters except one (time to onset of fatigue) in the auranofin treatment group. There were no significant differences between the treatment groups for any parameter of clinical efficacy. Of the laboratory parameters measured, only auranofin treatment produced statistically significant decreases in the concentration of IgA, IgG and IgM, with significant differences between treatments being detected in the case of IgA and IgG. Eight auranofin-treated and three hydroxychloroquine-treated patients were withdrawn because of adverse reactions before completing 48 weeks treatment. The commonest reason for stopping auranofin treatment was diarrhoea (5 cases). Three hydroxychloroquine-treated and two auranofin-treated patients were withdrawn from the study because of inefficacy of the trial drug. Auranofin had a more 'potent' biochemical profile than hydroxychloroquine, although more patients tolerated one year of treatment with the latter drug.
