Modern therapeutic approach in rheumatoid arthritis (RA) includes early use of disease-modifying anti-rheumatic drugs (DMARDs). DMARDs may influence the course of disease progression, and their introduction in early RA is recommended to limit irreversible joint damage. Among DMARDs, leflunomide and methotrexate are more utilised in pharmacological therapy. In the present work, we considered the effects of leflunomide, in comparison with those of methotrexate and to those of leflunomide-methotrexate combination on human cartilage to verify its effectiveness in arthritic disease, simulated by our experimental model. We measured in vitro the amount of glycosaminoglycans (GAGs) and the production of nitric oxide (NO) released into the culture medium of human articular cartilage treated with interleukin-1β (IL-1β), which promotes the cartilage destruction during articular disease. Leflunomide, in the presence of IL-1β decreased NO production and GAGs release respect IL-1β alone treated samples, in dose-related manner. Our results suggest that leflunomide is able to protect cartilage matrix from degradative factors induced by IL-1β with respect to methotrexate and leflunomide-methotrexate combination.
