Abstract | BACKGROUND AND OBJECTIVES: DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: Seventeen P-ANCA/MPO- ANCA-positive patients with MPA with mild to moderate renal involvement received MMF (1000 mg orally, twice daily) and CS (intravenous methylprednisolone, 1 to 3 g, followed by oral prednisone at 1 mg/kg per day). Oral CS were discontinued by month 6; MMF was continued through month 18. The primary outcome measure was remission by month 6 and stable renal function. Secondary endpoints included major relapses necessitating a switch to CYC plus CS, minor relapses requiring an increase in CS dosage, and adverse events. RESULTS: Thirteen of 17 patients enrolled achieved the primary outcome, and 4 failed because of insufficient response, relapse, or MMF intolerance. Twelve patients remained in remission through month 18, renal function remained stable, and proteinuria improved. Side effects of MMF were mild, transient, and responsive to dose adjustments in all patients except one. CONCLUSIONS: MMF represents an alternative to CYC for induction and maintenance of remission in patients with MPO- ANCA-associated MPA with mild to moderate renal disease.
