    Abstract

    Objectives: To assess the safety and efficacy of combination therapy in recent-onset rheumatoid arthritis (RA), with dose adjustments determined by response, in a clinic setting over 3 years.Methods: Disease-modifying antirheumatic drug (DMARD)-native patients with RA of median duration of 12 weeks (n = 61) attending an early arthritis clinic were treated with methotrexate, sulfasalazine, hydroxychloroquine, and fish oil. Dosage adjustments and additions of further DMARDs were contingent on response to therapy and tolerance. Outcome measures for efficacy were Disease Activity Score (DAS28), clinical remission, and modified Sharp radiographic score and for safety, adverse events, and DMARD withdrawal.Results: At baseline, subjects had at least moderately active disease (mean +/- SD DAS28 was 5.3 +/- 1.1), impaired function as measured by the modified Health Assessment Questionnaire (mHAQ) (0.9 +/- 0.5), and 37% had bone erosions. By 3 months, 29% were in remission; this increased to 54% at 3 years. The greatest fall in DAS28 and improvement in mHAQ scores occurred in the first 12 months. Erosions were detected in 62% at 3 years. The mean dose of parenteral glucocorticoid was equivalent to 0.1 mg/d of prednilsolone. After 3 years, 48% remained on triple therapy; fish oil was consumed by 75% of patients, and 21% used nonsteroidal anti-inflammatory drugs. Gastrointestinal intolerance was the most frequent unwanted event (leading to DMARD withdrawal in 17 patients). Sulfasalazine was most frequently withdrawn (30%).Conclusion: This implementation study demonstrates the feasibility, safety, and efficacy of combination therapy with inexpensive DMARDs, fish oil, and minimal glucocorticoid use, in routine clinical practice using predefined rules for dosage adjustment.
