Successful treatment of sarcoidosis-associated pulmonary hypertension with bosentan.

Sarcoidosis is a systemic granulomatous disease of unknown etiology, in which the lungs and intrathoracic lymph nodes are predominant sites of involvement. Pulmonary hypertension is a known complication of sarcoidosis. Treatment of sarcoidosis-associated pulmonary hypertension has traditionally focused on the initiation of systemic corticosteroids, but has had inconsistent results. We present a patient with sarcoidosis-associated pulmonary hypertension who achieved substantial clinical improvement with the dual endothelin receptor antagonist bosentan.
