Mycobacterial pulmonary infections after allogeneic bone marrow transplantation.
Allogeneic bone marrow transplant recipients are prone to pulmonary infections caused by a wide spectrum of organisms. Nonetheless, the recognition of lung disease caused by Mycobacterium tuberculosis in two patients and Mycobacterium avium-intracellulare in a third patient at the University of Texas M. D. Anderson Hospital represents the first report of these agents occurring in allogeneic marrow recipients. Diagnosis can be difficult due to atypical presentations, initial negative culture results, and the presence of more than one pathogen in these compromised hosts. In the case involving Mycobacterium avium-intracellulare infection, culture of material obtained by bronchoscopy established the diagnosis when repeated sputum samples showed no growth. A vigorous search for mycobacteria is suggested in allogeneic bone marrow transplant recipients with pulmonary infections.
