[Preliminary results in the therapy of psoriatic arthritis with mycophenolate mofetil]

Psoriatic arthritis concerns both the skin and the joints. Therapeutic interventions should therefore ideally improve both symptoms. Current disease modifying drugs are effective; however, they are usually limited to either psoriasis or arthritis.

The aim of this study was to analyze the therapeutic effects of a new immunosuppressive drug (Mycophenolate mofetil) in the treatment of psoriatic arthritis.

Six patients with psoriatic arthritis were treated with Mycophenolate mofetil for a period of 12 weeks and examined every 14 days (range of motion, joint swelling, joint deformity, PASI score (Psoriasis Area and Severity Index). In addition, a life quality assessment (SF-36 Health Survey) was performed. White and red blood count as well as inflammation parameter were controlled regularly.

6 patients could be included in a complete follow-up (5 men, 1 woman, average age 50.3 years, average duration of psoriasis 8.3 years, average duration of arthritis 5.7 years). Four of 6 patients showed relevant improvement in pain, mobility and degree of psoriatic skin effluorescences. Only 3 of 6 showed relevant improvement in life quality.

For the first time results of treatment of psoriatic arthritis with a new immunosuppressive drug (Mycophenolate mofetil) were presented. A positive influence on both, the arthritis and the psoriasis could be shown. These first observations warrant controlled, randomized clinical trials.
