Abstract

OBJECTIVE:

To compare the safety and efficacy of methotrexate (MTX) and gold sodium thiomalate (GSTM) in patients with active early erosive rheumatoid arthritis (RA) during 3 yr.

METHODS:

A total of 174 patients from two centres were randomly assigned to receive weekly i.m. injections of either 15 mg MTX or 50 mg GSTM for 1 yr in a double-blind fashion. Thereafter, the study was continued as an open prospective trial for an additional 2 yr with the same dose of MTX and half of the GSTM dose. Clinical and laboratory evaluations were carried out at baseline and at months 6, 12, 18, 24 and 36 in all patients, including withdrawals.

RESULTS:

An intention-to-treat analysis revealed inactivation ['clinical remission': no swollen/tender joints, erythrocyte sedimentation rate (ESR) of < 20 mm/h in males and < 30 mm in females, no corticosteroids within the last 4 weeks] in 33.3% of MTX patients and 37.9% of GSTM patients. The mean time to inactivation was insignificantly shorter with GSTM (MTX: 12.1 months; GSTM: 9.1 months; P = 0.06). At least marked improvement (> 50% reduction of the number of swollen/tender joints and of the ESR) was found in 78.2% (MTX) and 87.4% (GSTM). Withdrawal from the study due to toxicity was recorded in 16.1% of MTX and 52.9% of GSTM patients after a mean time of 30.6 and 6.1 months, respectively (P = 0.0001). In MTX and GSTM non-completers, inactivation was recorded in 24.2 and 54.7% of all patients. Among completers (54 and 34 patients, respectively), significant improvement compared to baseline was noted in all seven clinical variables (morning stiffness, overall joint pain, count of tender/swollen joints, Lansbury articular score, functional score and grip strength), ESR and C-reactive protein without significant intergroup differences. The steroid-sparing effect appeared more pronounced with GSTM.

CONCLUSION:

Over 36 months, treatment with MTX or GSTM induces inactivation ('clinical remission') of early and erosive RA in about one-third and at least marked improvement in four-fifths of patients (intention-to-treat analysis). Patients withdrawn from MTX or GSTM due to toxicity develop a clinical remission from the disease; this occurred more often with GSTM. Tolerability is significantly better with MTX.
