A Comparison of Oral Methylprednisolone Plus Azathioprine or Mycophenolate Mofetil for the Treatment of Pemphigus

Abstract

In 13 (72%) of 18 patients with pemphigus receiving oral methylprednisolone and azathioprine, complete remission was achieved after a mean +/- SD of 74 +/- 127 days compared with 20 (95%) of 21 patients receiving oral methylprednisolone and mycophenolate mofetil in whom complete remission occurred after a mean +/- SD of 91 +/- 113 days. The total median cumulative methylprednisolone dose used was 8916 mg (SD, +/-29 844 mg) in the azathioprine group compared with 9334 mg (SD, +/-13 280 mg) in the mycophenolate group. In 6 (33%) of 18 patients treated with azathioprine, grade 3 or 4 adverse effects were documented in contrast to 4 (19%) of 21 patients who received mycophenolate mofetil. Conclusion Mycophenolate mofetil and azathioprine demonstrate similar efficacy, corticosteroid-sparing effects, and safety profiles as adjuvants during treatment of pemphigus vulgaris and pemphigus foliaceus.
