Abstract

We investigated the relationship of Pneumocystis colonization, matrix metalloprotease levels in sputum, and airway obstruction in a cohort of human immunodeficiency virus (HIV)-infected outpatients. Pneumocystis-colonized subjects had worse obstruction of airways and higher levels of matrix metalloprotease-12 in sputa, suggesting that Pneumocystis colonization may be important in HIV-associated chronic obstructive pulmonary disease.
