Heart transplantation in a patient with eosinophilic granulomatosis with polyangiitis known as Churg-Strauss syndrome

Eosinophilic granulomatosis with polyangiitis (EGPA), also known as Churg-Strauss syndrome, is a rare systemic necrotizing vasculitis affecting smallto medium-sized vessels. EGPA is associated with severe asthma and eosinophilia. The most frequently involved organs are skin and peripheral nerves; however, EGPA may involve other organs, such as the gastrointestinal tract, kidney, and heart. Antineutrophil cytoplasm antibodies (ANCAs)-related abnormal immune reactions are known to be associated with EGPA, but only 30%–40% of patients have a positive marker of ANCA. ANCA-negative patients are at higher risk of cardiac involvement than ANCApositive patients. Cardiac involvement is one of the leading causes of mortality and could be resistant to conventional treatment. Early treatment with steroid plus cyclophosphamide is important because it could give chances of restoration of cardiac function. For patients undergoing heart transplantation, we should consider the severity of cardiac disease and the presence of systemic diseases, including vasculitis. Here, we report a case of a 25-year-old EGPA patient with cardiac involvement who eventually received heart transplantation for progressive heart failure, although treated with systemic corticosteroid with cyclophosphamide. EGPA patients undergoing heart transplantion are rarely reported worldwide, and this is the first case report in Korea. (Allergy Asthma Respir Dis 2015;3:159-163)
