Mycophenolate mofetil as a first-line steroid-sparing agent in the treatment of pemphigus vulgaris.

Pemphigus vulgaris (PV) is a life-threatening autoimmune bullous disorder. Although systemic corticosteroids are the standard treatment for PV, efficient transition to a steroid-sparing immunosuppressant is critical. There is significant debate in the literature as to what the optimal, first-line steroid-sparing agent should be in patients with PV. Mycophenolate mofetil (MMF), in particular, is a promising agent that should be strongly considered as a first-line steroid-sparing agent. The authors review treatment options for PV and describe a severe case treated successfully with prednisone and MMF as a first-line steroid-sparing agent. The patient's clinical improvement was rapid, and all PV lesions completely resolved. The dosage of prednisone was safely tapered using MMF, and the patient did not experience any flares or significant side effects during the course of treatment. Therapy for PV with systemic corticosteroids and MMF therapy was effective and well tolerated.
