Pemphigus: a treatment update.

Pemphigus is a group of rare autoimmune mucocutaneous bullous diseases with potential significant morbidity and mortality. The two main subtypes are pemphigus vulgaris (PV) and pemphigus foliaceus (PF). Systemic corticosteroid use and other advances in management have dramatically decreased the mortality rate for pemphigus. At present, the primary cause of morbidity and mortality is complications from treatment. Thus, the goal of pemphigus management is to induce and maintain remission with the lowest possible doses of medication and with the fewest side effects. Although our scientific knowledge of pemphigus is advancing and our treatment options are expanding, there are still very few randomized, controlled studies to evaluate the true effectiveness of the available therapies. Here we review the available treatment options and novel therapies for pemphigus and the supporting data.
