Background: Rheumatoid arthritis (RA) is a chronic inflammatory condition. The condition can affected many tissues throught out the body, but the joints are usually most severely affected. The high incidence of RA, the conventional treatments and the experimental observation have shown by combination therapy, the disease symptoms of the patients reduce. To compare the efficacy and tolerability of single-agent Hydroxychloroquin (HCQ) with combination therapies composed of (HCQ) and Methotrexate (MTX) and (HCQ), (MTX) and Sulfasalazin (SSZ) in active rheumatoid arthritis patients with additive arthritis. Methods: One hundred and twenty RA patients with active arthritis (male/female: 30/90) who were treated in rheumatology clinic between 2003 and 2005 were enrolled in this trial. Patients treated with (HCQ) alone(200 mg/day)were include in group (I), patients treated with combination of (HCQ) (200 mg/day)and (MTX) (7.5mg/week)in group (II),and patents treated with combination of (HCQ) (200mg/day),(MTX) (7.5mg/week)and (SSZ)(1 gr/day)in group (III), Forty patients (male/female:10/30) in group (I),(II) and (III)were eligible for statistical analysis at the end of study. Changes in variable were compared by the T-test. Results: The combination of (MTX), (HCQ)and (SSZ) and the combination of (MTX) and (HCQ) were more effective regarding the clinical and laboratory parameters than (HCQ) alone (P<0.05). Moreover the combination of (MTX), (HCQ) and (SSZ) was more effective than the combination of (MTX) and (HCQ) (P<0.05). Combination therapies seem to be more effective and no more toxic than monotherapy in RA patients with additive arthritis. Conclusion: Combination therapy with methotrexate, hydroxychloroquin and sulfasalazin is more effective than hydroxychloroquin alone or a combination of methotrexate and hydroxychloroquin in RA. We suggest starting combination therapy for the patients with early RA, when the diagnosis has been established.
