OBJECTIVES: We have assessed indications, duration and tolerability of treatment with mycophenolate mofetil (MMF) in patients with diffuse cutaneous systemic sclerosis (dcSSc), and compared clinical outcome with a control cohort treated with other immunosuppressive drugs. METHODS: The clinical records of 109 patients treated with MMF and 63 control subjects receiving other immunosuppressive drugs were reviewed. Data covering a 5-yr period from commencement of treatment or until last assessment date were collected. RESULTS: MMF and control groups were well-matched in terms of basic demographic and clinical parameters. Treatment with MMF was very well tolerated. Of all patients, 12% experienced adverse reactions with gastrointestinal (GI) tract disturbances and infections being most frequent. MMF was discontinued due to disease stabilization in 9%, side effects in 8% and no effect on the disease activity in 14% of the patients. There was a significantly lower frequency of clinically significant pulmonary fibrosis in the MMF-treated cohort (P = 0.037) and significantly better 5-yr survival from disease onset and from commencement of treatment (P = 0.027 and P = 0.012, respectively). There was no significant difference between the two groups in terms of modified Rodnan skin score and forced vital capacity (FVC) change. CONCLUSIONS: MMF is very well tolerated and appears to be at least as effective as the other current therapies for dcSSc. Our results provide support for further evaluation of MMF in a prospective trial.
