Background and Objective: The emergence of resistance to drugs used to treat tuberculosis (TB), and particularly multidrug-resistant TB, has become a significant public health problem globally. In spite newer modalities for diagnosis and treatment of TB, unfortunately, millions of people are still suffering and dying from the disease. The present study was aimed to study the prevalence of initial drug resistance and the treatment outcome at the end of 6 months in TB patients attending a dedicated TB outpatient department (OPD) in North India. Materials and Methods: A cross-sectional, observational study was carried out on 100 patients of newly diagnosed pulmonary TB with or without glandular involvement attending TB OPD of a tertiary care hospital over a period of 6 months. Results: Culture positivity was encountered in 82% of the cases, while 14% were smear positive though culture negative. Out of all culture positive patients, 56.1% were susceptible to all antitubercular drugs, while 43.9% were resistant to one or other antitubercular drugs (isoniazid, rifampicin, streptomycin or ethambutol). Of the 46 drug-susceptible cases, 93.48% got cured, while 2.2% defaulted and 2.2% had treatment failure. About 86.1% of the 36 initial drug resistant were cured with 2RHZE/4RH, while 5.6% (n = 2) defaulted treatment and 8.3% were treatment failures. Conclusion: Treatment outcomes of this small group of drug-resistant pulmonary TB patients treated with the standardized regimen was encouraging in this setting. Close attention needs to be paid to ensure early identification of drug-resistant cases; good laboratory methodology and quality control measures; regular supply of quality antitubercular drugs; adherence to the prescribed regimen; effective patient education and counseling; and to the timely recognition and treatment of adverse drug reactions for better treatment outcome.
