Therapeutic plasma exchange as adjunct therapy for bullous pemphigoid

Bullous pemphigoid (BP) is a rare autoimmune blistering disease caused by pathogenic antibodies which deposit into the dermo‐epidermal junction. We present a case of bullous pemphigoid in a young female refractory to initial therapy with immunosuppressives and steroids who experienced significant improvement in blister burden after a course of adjunct therapeutic plasma exchange (TPE). This case report provides valuable insight into the benefit of utilizing TPE for BP and provides treatment specifics regarding use of TPE in a patient with BP.
