Abstract:
:To assess whether PCR is applicable for monitoring the efficacy of antituberculous treatment, respiratory specimens obtained during treatment and follow-up from sputum smear-positive tuberculosis (TB) patients were examined. First, results of smear, culture, and PCR for Mycobacterium tuberculosis complex (MTB) and an internal inhibition control (MCC) were correlated retrospectively on 1,601 respiratory specimens from patients with no previous cultures of MTB. MTB optical density (OD) values increased to a maximum level of 3.5 to 4.0, with both increasing numbers of acid-fast bacilli and CFU. MTB/MCC OD ratios also increased with both smear and culture grading and correlated significantly better with both than the MTB OD value. Second, changes in MTB OD values and MTB/MCC OD ratios were compared with microscopy and culture for MTB in monthly sputa obtained during treatment and follow-up in 22 smear-positive pulmonary TB patients. Declines in MTB/MCC OD ratios during antituberculous treatment and follow-up were observed. Patients with moderate disease reached the baseline after 6 to 8 months of standard antituberculous treatment regimen, whereas patients with extensive disease were predicted to reach the baseline 1 year or more after the initiation of treatment. Although PCR detects both dead and live bacteria, we believe that PCR can be used to assess the efficacy of antituberculous treatment since increases or slow reductions in MTB/MCC OD ratios would indicate nonoptimal treatment, noncompliance, reduced bioavailability of drugs, or resistant strains of MTB and thereby would identify patients at risk for treatment failure or reactivation.
