Sputum examination was carried out at the 2nd, 4th and 6th month as required by RNTCP. All HIV seropositive pulmonary tuberculosis cases were treated with Category 1 regimen, while HIV seronegative patients were treated with either Category 1 or Category III regimens as per RNTCP guidelines.

Factors that were significantly associated with treatment failure death were old age OR 95 CI HIV co-infection OR 95 CI and previously treated tuberculosis OR 95 CI . These high rates of drug resistance and treatment failure in this area suggest that initial sputum cultures and drug susceptibility testing for Mycobacteria should be performed in all patients who have been previously exposed to anti-tuberculous drugs and HIV testing should be performed on all patients with tuberculosis.
