Comparison of intra-articular glucocorticoid injections with DMARDs versus DMARDs alone in rheumatoid arthritis.

BACKGROUND

Intra-articular triamcinolone in combination with DMARDs may be able to achieve faster and tighter control of disease activity in early rheumatoid arthritis that may be the key to preventing or minimizing later deformities.

OBJECTIVE

To compare the efficacy of a combination of Disease Modifying Anti-Rheumatoid Drugs (DMARDs) with Intra-articular Glucocorticoids versus only DMARDs in a group of patients with early Rheumatoid Arthritis (RA).

METHODS

Fifty patients diagnosed as Rheumatoid Arthritis (RA) by American Rheumatology Association (ARA) criteria (1987) with disease duration less than two years were randomized into two groups. The Control group received a combination of Methotrexate 15 mg daily with Sulfasalazine 2 gm daily for 3 months and the Study group received the above combination along with Intra-articular injections of Triamcinolone acetate (40 mg per ml) in each of the swollen joints at the start of the study. Outcome was assessed in terms of Disease Activity Score (DAS-28), American College of Rheumatology (ACR) 20/50/70 criteria and number of rescue medications used at the end of 3 months.

RESULTS

The study group had significant reductions in DAS 28 scores (3.39 versus 4.99 in control group) and significantly more subjects achieved the ACR 20/50/70 criteria at the end of 3 months (100/60/36% versus 84/20/0%) Secondary end-points like tender and swollen joint count, ESR, early morning stiffness, health assessment questionnaire (HAQ) scores and general health status were significantly reduced in the study group. Also, significantly lesser rescue medications were needed in the study group.

CONCLUSION

Combination of DMARDs with Intra-articular corticosteroids is significantly better than DMARDs alone in early RA.
