title: Multidrug-resistant tuberculosis among different types of suspected cases: Study from New Delhi.
abstract: There are limited data of multidrug-resistant tuberculosis (MDR-TB) diagnosed in various patient categories by implementing Programmatic Management of Drug Resistant TB (PMDT) using line probe assay (LPA) from our country. Samples from presumptive MDR-TB from five districts of New Delhi were subjected to LPA from 1st October 2011 to 31st December 2014. The MDR-TB diagnosed in 4th & 5th month follow-up positives were significantly higher than other categories of the patients. Only 3/232 (2.2%) RIF resistants were diagnosed among smear negative re-treatment cases. The data suggest interim cost-benefit analysis of the program especially among smear negatives retreatment cases.
