Abstract
India is one of the high burden countries for tuberculosis (TB) including multi-drug resistant TB (MDR-TB) and extensively-drug resistant (XDR) TB. Drug-resistant (DR) TB has threatened the TB care and is a major health problem in many countries; treatment of DR TB has been difficult requiring use of reserve or second-line drugs, cost factors, has extensive side-effect profile and long duration of treatment. Treatment in MDR-TB are increasingly becoming individualised mainly due to preference for oral over injectable, results of drug susceptibility testing (DST), population resistance levels, history of previous TB treatment, drug tolerability and drug-to-drug interactions. Bedaquilline (BDQ) and delaminid (DLM) are new drugs available for treatment of these patients. World Health Organization (WHO) recommends use of BDQ in more than 15y (>15kg) patients only. Under Revised National Tuberculosis Control Programme (RNTCP) the use of this drug is recommended for patients older than 18 y only. Under RNTCP, the use of DLM is approved in children 6 y and above. Pediatric MDR/XDR TB treatment outcome with newer anti-TB drugs and regimen is lacking. Children when treated with individualized regimens have improved survival.
