Abstract
Background:
Bedaquiline has not been extensively studied among HIV drug-resistant tuberculosis (DR-TB) co-infected patients. We compared treatment outcomes in DR-TB patients treated with bedaquiline- and linezolid-containing regimens to historic controls treated with second-line injectable-containing regimens.
Methods:
Retrospective cohort study of consecutive DR-TB patients initiated on bedaquiline- and linezolid-containing regimens at a TB referral hospital in KwaZulu-Natal, South Africa. Participants were prospectively followed through 24 months for treatment outcome, and adverse events. Outcomes were compared to a historic control cohort of DR-TB HIV patients enrolled at the same facility prior to bedaquiline introduction.
Results:
Adult DR-TB patients initiating bedaquiline between January 2014 and November 2015 were enrolled (N=151). The majority of patients were female (52%), HIV co-infected (77%) and on antiretroviral therapy (100%). End of treatment outcomes included cure (63%), TB culture conversion (83%), completion (0.7%), loss-to-follow-up (15%), treatment failure (5%), and death (17%). Compared to historic controls (N=105), patients treated with bedaquiline experienced significantly higher TB culture conversion and cure, with significantly lower mortality. Adverse effects were common (92%) and most frequently attributed to linezolid (24.1%). QT segment prolongation was common but without clinical sequelae.
Conclusion:
Treatment with bedaquiline- and linezolid-containing regimens was associated with improved treatment outcomes and survival in DR-TB HIV patients.
