Impact of bedaquiline on treatment outcomes of multidrug-resistant tuberculosis in a high-burden country

Evaluation of novel anti-tuberculosis (TB) medicines for the treatment of multidrug-resistant (MDR)-TB continues to be of high interest on the TB research agenda. We assessed treatment outcomes in patients with pulmonary MDR-TB who received bedaquiline containing treatment regimens in the Republic of Moldova, a high-burden country of MDR-TB. We systematically analysed the "SIMETB" national electronic TB database in the Republic of Moldova and performed a retrospective propensity score matched comparison of treatment outcomes in a cohort of patients with MDR-TB who started treatment during 2016-2018 with a bedaquiline-containing regimen (bedaquiline cohort) and a cohort of patients treated without bedaquiline (non-bedaquiline cohort). Following propensity score matching, 114 patients were assigned to each cohort of MDR-TB patients. Patients in the bedaquiline cohort had a higher 6 month sputum culture conversion rate than those in the non-bedaquiline cohort, (66.7% 40.3%, p
