Global treatment outcomes of extensively drug-resistant tuberculosis in adults: A systematic review and meta-analysis.

Introduction: Historically, extensively drug-resistant tuberculosis has been notoriously difficult to treat with devasting outcomes. As we are coming to the end of an era where the 2006 extensively drug-resistant tuberculosis definitions and old treatment regimens are being replaced, we aimed to estimate the proportion of extensively drug-resistant tuberculosis patients globally who achieved successful treatment outcomes.

Methods: We conducted a systematic review of PubMed/MEDLINE, Scopus, Web of Science, and Embase from January 1, 2005, through April 3, 2023.

Efficacy and Tolerability of Concomitant Use of Bedaquiline and Delamanid for Multidrug- and Extensively Drug-Resistant Tuberculosis: A Systematic Review and Meta-Analysis.

The introduction of two novel drugs, bedaquiline and delamanid, has given hope for better and shorter treatments of drug-resistant tuberculosis. A systematic review was conducted to evaluate the efficacy and safety of concomitant bedaquiline and delamanid administration. Pooled estimates of World Health Organization-defined favorable treatment outcome and significant QTc-interval prolongation (QTc ≥500 ms or ≥60 ms increase from baseline) were calculated using a random-effects model.
