title: Comparison of prognosis of pulmonary diseases caused by Mycobacterium avium and by Mycobacterium intracellulare.
abstract: A total of 55 patients with pulmonary disease caused by Mycobacterium avium and by Mycobacterium intracellulare were compared for their prognosis. Causative mycobacteria were identified by the DNA probes (Gen-Probe) method. Of the 55 patients, 28 had pulmonary disease caused by M avium and the remaining 27, by M intracellulare. Of the former group, four patients had progressive disease, and three of them died during the observation period. In contrast, only one of the latter group had progressive disease. On the other hand, only one of the former group was cured. In contrast, six of the latter group were cured, showing the closure of cavity and the disappearance of mycobacteria from the sputum. The prognosis of pulmonary disease caused by M avium appears to be worse than that caused by M intracellulare.
