[Pulmonary complications in patients with adult T-cell leukemia].
In order to investigate the character of pulmonary complications in patients with adult T-cell leukemia (ATL), a pathological and bacteriological study was performed in 92 autopsy cases with hematologic malignancies including 17 cases of ATL and 103 autopsy cases with solid malignancies from 1981 to 1990. Among 17 cases with ATL, pulmonary complications were seen in 16 cases (94.1%); pulmonary infection in 14 (82.3%), leukemic cell pulmonary infiltration in 9 (52.9%), pulmonary hemorrhage in 5 (29.4%), pulmonary alveolar calcinosis in 2 (11.8%), and idiopathic interstitial pneumonia in 2 (11.8%). The causative microorganisms were virus in 10; 9 of which were cytomegalovirus, followed by bacteria infection in 4 cases, mainly pseudomonas aeruginosa, and fungal infection in 3, mainly cryptococcus. pneumocystic carinii and mycobacterium tuberculosis were not detected. It is suggested that patients with ATL are severely compromised with chiefly cellular immunodeficiency, and administration of sulfamethoxazole-trimethoprim and isoniazid is very effective in prevention of pneumocystis carinii pneumonia and pulmonary tuberculosis.
