Abstract
BACKGROUND: In Peru, a treatment approach for extensively drug-resistant tuberculosis (XDR-TB) incorporating World Health Organization Group 5 drugs and patient-centred care has achieved 65% success. To extend this approach to pre-XDR-TB patients, we evaluated this population separately. OBJECTIVES: To assess programmatic management of pre-XDR-TB. METHOD: Retrospective study using the official national registry from 2011 to 2014. Cases were separately evaluated according to resistance to fluoroquinolones (FQs) (pre-XDR-F) or to second-line injectables (SLIs) (pre-XDR-I). RESULTS: Of 610 pre-XDR-TB patients, 120 (20%) had pre-XDR-F and 490 (80%) had pre-XDR-I. Pre-XDR-F cases were older (34 years vs. 28 years, P, 0.001) and a higher proportion had previously received two or more regimens (70% vs. 38%, P, 0.001). Among the 452 patients who started treatment in 2011-2013, treatment success was 43.3%, 26.5% were lost to follow-up, 12.1% died and 13.7% failed treatment. Success was higher in pre-XDR-I (48.5%) than pre-XDR-F (21.4%) patients. History of previous treatment (OR 2.23, 95%CI 1.52-3.38) and pre-XDR-F (OR 2.39, CI 1.18-4.83) were associated with unsuccessful outcomes. CONCLUSIONS: Programmatic management of pre-XDR-TB has not been successful, particularly in pre-XDR-F patients, with lower rates of success than those achieved in the same setting for XDR-TB. The strategy used for XDR-TB should be extended to pre-XDR-TB patients in Peru.
