OBJECTIVE: To document the level of drug resistance in MDR-TB patients and to characterize management capacities for their medical care and MDR-TB treatment outcomes in the Kharkiv region of Ukraine. This area has one of the highest frequencies of MDR-TB worldwide.METHODS:
A retrospective observational cohort study was performed on registry data from the regional anti-TB dispensary in Kharkiv. All microbiologically confirmed MDR-TB patients registered in 2014 were included. Diagnostic, treatment and post-treatment follow-up data were analysed.RESULTS:
Of 169 patients with MDR-TB, 55.0% had pre-extensively drug-resistant (pre-XDR) or XDR resistant patterns. Rapid molecular diagnosis by GeneXpert and liquid M. tuberculosis cultures were only available for 66.9% and 56.8% of patients, respectively. Phenotypic drug-susceptibility testing
(DST) for high priority TB drugs (bedaquiline, linezolid, clofazimine) were not available. DST for later generation fluroquinolones was available only in 53.2% of patients. 50.9% of patients had less than 4 drugs in the treatment regimen proven to be effective by DST. More than 23.1% of patients
with MDR-TB failed their treatment and only 45.0% achieved a cure.CONCLUSION: The high prevalence of MDR-TB and poor MDR-TB treatment outcomes in the Kharkiv region, is associated with substantial shortages in rapid molecular and phenotypic DST, a lack of high priority MDR-TB drugs,
poor treatment monitoring and follow-up capacities.
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.
