Enzyme and combination therapy with cyclosporin A in the rat developing adjuvant arthritis.

| Abstract |
Recent knowledge of the pathophysiology of rheumatoid arthritis and the mechanism of drug effects have enabled the use of new drugs and drug combinations in rheumatoid arthritis therapy. This study investigates the efficacy of both enzyme therapy and combined therapy with cyclosporin in rats with adjuvant arthritis. Rats with adjuvant-induced arthritis were administered either cyclosporin A (2.5 or 5.0 mg/kg/day per os), a mixture of enzymes (Phlogenzym (PHL); 45 mg/kg twice daily intrarectally), or a combination of 2.5 mg cyclosporin A and 90 mg PHL for a period of 40 days from the adjuvant application. Levels of serum albumin, changes in hind paw swelling and bone erosions were measured in rats as variables of inflammation and arthritis-associated destructive changes. Treatment with 5 mg of cyclosporin A, as well as with the combination therapy with cyclosporin A plus PHL, significantly inhibited both the inflammation and destructive arthritis-associated changes. However, 2.5 mg of cyclosporin A and PHL alone inhibited these disease markers, although to a lesser extent and at a later stage of arthritis development. The results show the inhibitory effect of enzyme therapy on rat adjuvant arthritis, as well as the efficacy of a low dose of cyclosporin A given in combination with enzyme therapy, which may be useful in the treatment of rheumatoid arthritis.
