Marked pulmonary function abnormalities in a case of HIV-associated pulmonary hypertension.

Abstract

Recent reports have suggested an association between primary pulmonary hypertension and human immunodeficiency virus (HIV) infection. This appears to be an accelerated syndrome, associated with a relatively brief duration of symptoms, yet prominent right ventricular failure and severe pulmonary hypertension on presentation. We present a case of a primary pulmonary hypertension in a 35-year-old HIV-seropositive hemophiliac. His accelerated clinical course is consistent with previously reported cases of HIV-related pulmonary hypertension. However, this patient's pulmonary function tests revealed marked hyperinflation, a decreased diffusing capacity, and no airflow obstruction. To our knowledge, this very usual constellation of pulmonary function changes has not been described previously in this syndrome.
