Setting
Drug resistance threatens tuberculosis (TB) control, particularly among HIV-infected persons.
Objective
We surveyed antiretroviral therapy (ART) programs from lower-income countries on prevention and management of drug-resistant TB.
Design
We used online questionnaires to collect program-level data in 47 ART programs in Southern Africa (14), East Africa (8), West Africa (7), Central Africa (5), Latin America (7) and Asia-Pacific (6 programs) in 2012. Patient-level data were collected on 1,002 adult TB patients seen at 40 of the participating ART programs.
Results
Phenotypic drug susceptibility testing was available at 36 (77%) ART programs, but only used for 22% of all TB patients. Molecular drug resistance testing was available at 33 (70%) programs and used for 23% of all TB patients. Twenty ART programs (43%) provided directly observed therapy (DOT) during the whole treatment, 16 (34%) during intensive phase only and 11 (23%) did not follow DOT. Fourteen (30%) ART programs reported no access to second-line TB regimens; 18 (38%) reported TB drug shortages.
Conclusions
Capacity to diagnose and treat drug-resistant TB was limited across ART programs in lower income countries. DOT was not always implemented and drug supply was regularly interrupted, which may contribute to the global emergence of drug resistance.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
