    Abstract:
    BACKGROUND/PURPOSE: Multidrug-resistant tuberculosis (MDR-TB) represents 5% of TB cases globally. In Egypt, it represents 11.4% of TB cases (2.2% of new and 38.2% of previously treated). Our objectives were to evaluate the treatment outcomes and determine the associated prognostic factors among the first national treatment cohort of MDR-TB from 2006 to 2010. METHODS: All patients diagnosed with MDR-TB from July 2006 to December 2010 who were admitted to Abbassia Chest Hospital, the first Egyptian national center established for MDR-TB treatment, were included. They were followed up clinically, radiologically, and bacteriologically by sputum smear, culture, and drug-susceptibility testing at regular intervals. Individualized treatment regimens were prescribed according to each patient's drug-susceptibility testing and the drug treatment history. Patients received at least five effective drugs. Outcome rates, and crude and adjusted odds ratios of unsuccessful outcomes were calculated. RESULTS: The number of bacteriologically proven MDR-TB patients was 228, of which 225 were pulmonary cases. Half of the cases showed moderate or extensive lung lesions, and 15.8% were diabetics. A total of 158 (119 cured and 39 completed treatment) patients achieved successful outcome (69.3%), 16 (7.1%) failed treatment, 27 (11.8%) were lost to follow up, and 27 (11.8%) died. Predictors of unsuccessful outcome were delay in sputum culture conversion to 2 months or more, moderate or extensive lung lesions, and a history of diabetes. CONCLUSION: A treatment success rate of approximately 69% was achieved with the first national treatment cohort of MDR-TB under the Egyptian program. Predictors of unsuccessful treatment were delayed culture conversion, moderate or extensive lung affection, and diabetes.
