jointly sponsored this new practice guideline on the treatment of drug-resistant tuberculosis (DR-TB). The document includes recommendations on the treatment of multidrug-resistant TB (MDR-TB) as well as isoniazid-resistant but rifampin-susceptible TB. Methods: Published systematic reviews, meta-analyses, and a new individual patient data meta-analysis from 12,030 patients, in 50 studies, across 25 countries with confirmed pulmonary rifampinresistant TB were used for this guideline. Meta-analytic approaches included propensity score matching to reduce confounding. Each recommendation was discussed by an expert committee, screened for conflicts of interest, according to the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) methodology. Results: Twenty-one Population, Intervention, Comparator, and Outcomes questions were addressed, generating 25 GRADE-based recommendations. Certainty in the evidence was judged to be very low, because the data came from observational studies with significant loss to follow-up and imbalance in background regimens between comparator groups. Good practices in the management of MDR-TB are described. On the basis of the evidence review, a clinical strategy tool for building a treatment regimen for MDR-TB is also provided. Conclusions: New recommendations are made for the choice and number of drugs in a regimen, the duration of intensive and continuation phases, and the role of injectable drugs for MDR-TB. On the basis of these recommendations, an effective all-oral regimen for MDR-TB can be assembled. Recommendations are also provided on the role of surgery in treatment of MDR-TB and for treatment of contacts exposed to MDR-TB and treatment of isoniazid-resistant TB.

It is estimated that 33,000 children develop multidrug-resistant tuberculosis (MDR-TB) each year. In spite of these numbers, children and adolescents have limited access to the new and repurposed MDR-TB drugs. There is also little clinical guidance for the use of these drugs and for the shorter MDR-TB regimen in the pediatric population. This is despite the fact that these drugs and regimens are associated with improved interim outcomes and acceptable safety profiles in adults. This review fills a gap in the pediatric MDR-TB literature by providing practice-based recommendations for the use of the new (delamanid and bedaquiline) and repurposed (linezolid and clofazimine) MDR-TB drugs and the new shorter MDR-TB regimen in children and adolescents.

Multidrug-resistant tuberculosis (MDR-TB) is on the rise, and is difficult to treat. The approval of two new drugs, bedaquiline and delamanid, and growing evidence for the use of linezolid, offer renewed hope for addressing MDR-TB. However, access to these medicines remains a significant challenge. These drugs have not been registered for TB in most settings; barriers to preapproval access persist; and high pricing and intellectual property restrictions limit access. Many unanswered research questions about optimal use of these drugs also limit access, particularly for vulnerable populations. This review outlines challenges in accessing drugs encountered from the perspective of clinicians, patients and affected communities, and offers potential solutions.

Affecting both mother and the existing pregnancy, tuberculosis (TB) increases the likelihood of poor birth outcomes. Despite substantial clinical need for TB prevention and treatment, pregnant women remain neglected by research initiatives. As members of 3 community advisory boards that provide input into TB drug trials, we offer a community perspective on the inclusion of pregnant women in TB drug research and discuss (1) our perspective on the risk/benefit tradeoff of including pregnant women in research to address different forms of TB; (2) recent examples of progress in this area; (3) lessons learned from the human immunodeficiency virus research field, where pregnant women have enjoyed better-although imperfect-representation in research; and (4) recommendations for different stakeholders, including researchers, regulatory authorities, ethics committees, and policymakers.
