Transtracheal aspiration in diagnosis of sputum-smear--negative tuberculosis. 1977

H Thadepalli, and K Rambhatla, and A H Niden

Of 4,200 patients admitted to an acute-care county hospital, 126 (3%) were proved to have pulmonary tuberculosis, among whom 35 (28%) had several sputum smears negative for acid-fast bacilli. On transtracheal aspiration, 31 to 35 had acid-fast bacilli in the aspirate. Eighteen of these 35 (51%) patients had associated infections caused by aerobic or anaerobic bacteria. Tuberculin skin tests were negative in 14 of 35 patients with negative sputum specimens (40%). Ten of 18 patients (56%) with associated bacterial infections had negative skin tests to purified protein derivative. Smear and culture of transtracheal aspirate for tubercle bacilli may be invaluable in establishing the diagnosis when pulmonary tuberculosis is suspected.

D000995 Antitubercular Agents Drugs used in the treatment of tuberculosis. They are divided into two main classes: "first-line" agents, those with the greatest efficacy and acceptable degrees of toxicity used successfully in the great majority of cases; and "second-line" drugs used in drug-resistant cases or those in which some other patient-related condition has compromised the effectiveness of primary therapy.
