[Basic therapeutic combination therapy in chronic polyarthritis: an overview].

Therapy of rheumatoid arthritis with a combination of several disease-modifying drugs aims towards better control of the disease than achievable by monotherapy. Based on a broad variety of clinical studies, revealing more or less positive results, several combinations have been suggested: the inclusion of cyclosporin into combinations with methotrexate, the inclusion of sulfasalazine into combinations with methotrexate, the combined use of two chemotherapeutic substances, including methotrexate, azathioprine and cyclophosphamide, the inclusion of chloroquine derivatives into such or other combinations, and the combination of methotrexate with injectable gold. The validity of some of the studies is affected by high drop out rates and by the unknown influence of concomitant therapy with corticosteroids. Our own beneficial experience with the triple combination of methotrexate with azathioprine and chloroquine in 21 patients with refractory rheumatoid arthritis is summarized.
