Abstract:

OBJECTIVE: To assess the importance of monitoring sputum conversion as an early treatment indicator of treatment success.

METHODS: Retrospective analysis of sputum conversion in a cohort of ‘cured’ tuberculosis patients.

RESULTS: Of 65 (95%) patients whose sputum converted in the third month of treatment, 62 were cured; only 21 of 35 (60%) patients whose sputum was still positive at the end of three months of treatment were ultimately cured.

CONCLUSION: Sputum conversion during the third month of treatment is an important predictor of treatment success; failure to convert predicts treatment failure.
