Treatment of pulmonary infections caused by mycobacteria of the Mycobacterium avium-intracellulare complex

Abstract

Sixty-four patients with pulmonary infection caused by mycobacteria of the M avium-intracellulare complex have been reviewed. Patients who were asymptomatic on presentation often had a benign course but some developed progressive disease. Symptomatic patients who were not treated usually deteriorated. Various treatment regimens were used. Successful treatment was achieved in the majority of patients using a combination of isoniazid, rifampicin, and either ethambutol or streptomycin given for 24 months. Other forms of treatment given including multiple drug regimens were not as effective.
