ABSTRACT
We studied the effects of D-penicillamine (DP) on the clinical response, immunoinflammatory parameters and the lymphocyte subsets in 46 patients with rheumatoid arthritis (RA). Patients were evaluated before the start of the drug and then at 3 and 9 months during the follow up. 38 of 46 (82.6%) patients could continue DP treatment for over 9 months, while in 8 the drug was withdrawn due to adverse effects. Improvement in the various disease activity indices of more than 50% (responders) was seen in 25 of 38 (65.8%) patients. Responders showed a significant decrease in the serum IgA and IgM at 9 months, and in IgM only at 3 months. The serum levels of C3 and C4 did not show any significant change. Serum levels of C-reactive protein and rheumatoid factor (RF) showed a significant decrease at 3 and 9 months. A significant decrease in CD3+ and CD4+ lymphocytes along with a fall in CD4+/CD8+ lymphocyte ratio was also seen in responders at 3 and 9 months, compared to the baseline. Our results suggest that DP may have immunomodulatory action in RA.
