A large meta-analysis of observational studies that provided the basis for the recent makeover of global recommendations for multidrug-resistant tuberculosis (MDR-TB) treatment shows that newer and repurposed drugs produced better outcomes and fewer deaths than older treatments.
The meta-analysis of 50 studies involving 12,000 patients from 25 countries, published yesterday in The Lancet, found that bedaquiline, linezolid, levofloxacin, and moxifloxacin were associated with greater treatment success and reduced mortality compared with the previously recommended first-line treatments, while clofazimine and carbapenem antibiotics were associated with significantly improved treatment outcomes (but not reduced mortality)
