Influence of total glucosides of peony combined with leflunomide serum TNF-α,IL-8 in patients with psoriatic arthritis / 重庆医学

ABSTRACT

Objective To observe the influence of total glucosides of peony (TGP) combined with leflunomide on serum level of TNF-α,IL-8 in the patients with psoriatic arthritis(PsA) ,to evaluate its efficacy and safety and to preliminarily study its action mechanism .Methods The open clinical study was adopted .36 patients with PsA were treated by TGP combined with leflunomide for 12 weeks .at the same time 20 healthy control were selected .The double-antibody sandwich enzyme-linked immunosorbent assay (ELISA) was adopted to detect the level of serum TNF-α and IL-8 before treatment and in 12 weeks after treatmention the two groups .The Psoriasis Area And Severity Index (PASI) was adopted as the main effective index and the Health Assessment Ques-tionaire(HAQ) was taken as the secondary effective index .The level of CRP ,ESR ,TNF-α,IL-8 before and after treatment were an-alysed .Results The serum TNF-α,IL-8 levels before therapy in the poriatic arthritis group were significantly higher than those in the normal control group(P0 .05) .Conclusion TGP combined leflunomide for treating PsA has better effect and better safety ,which could play the role by influencing serum TNF-α,IL-8 levels .
