Initial experience of bedaquiline implementation under the National TB Programme at NITRD, Delhi, India
2019
Abstract Background Bedaquiline (BDQ) was approved for treatment of drug resistant TB (DR-TB) under Conditional Access Programme (CAP) of Revised National Tuberculosis Control Programme (RNTCP) and was also implemented in the National Institute of TB and Respiratory Diseases (NITRD). We present early efficacy and safety of BDQ containing regimens for DR-TB. Objective To ascertain the early efficacy and safety of Bedaquline containing regimens in treatment of DR-TB. Methods BDQ containing regimens along with other drugs were designed as per WHO recommendations for DR-TB patients. They were followed up for sputum smear and culture conversion, adverse events during the treatment. Results A cohort of 290 DR-TB patients (Median age-29.77) were initiated on BDQ containing regimens. Of the available Sputum results, smear conversion was seen in 51% and 91% patients at the end of 1st week and 3rd month respectively. Similarly, 93% and 98% patients had culture conversion at the end of 3rd and 6th month respectively. 201 adverse events (AE) including 47 deaths were reported among 109 patients. QTc prolongation was seen in 29% patients but only 4 required discontinuation of BDQ. Lost to follow up of treatment was about 6%. Conclusion Bedaquiline along with an optimized background regimen has shown early sputum conversion in larger number of difficult to treat patients having additional resistance of second line drugs along with INH and Rifampicin. The regimen is feasible in programmatic conditions and is relatively safe.
