title: [Pulmonary complications after allogeneic hematopoietic stem cell transplantation].
abstract: We investigated the occurrence of pulmonary complications in patients who underwent allogeneic hematopoietic stem cell transplantation at our institution. Pulmonary complications were observed in 12 out of 60 patients. Interstitial pneumonia developed in 12 cases: 7 idiopathic, 2 cytomegalovirus-associated, 1 P. carinii, 1 HSV, and 1 HHV-6-associated. HSV- and HHV-6-associated pneumonias were exhibited 100 days after transplantation. PCR analysis was diagnostically useful for detection of viral DNA in bronchial alveolar lavage fluid. Respiratory disease with airway obstruction was observed in 4 patients with chronic graft-versus-host disease, and all 4 had a history of interstitial pneumonia. Three patients died of respiratory failure. Mycobacicrium avium complex was detected in 2. Exacerbation of respiratory failure may be associated with mycobacterial infection.
