RESUMO

BACKGROUND: The impact of low body mass index (BMI) at initiation of rifampicin-resistant tuberculosis (RR-TB) treatment on outcomes is uncertain. We evaluated the association between BMI at RR-TB treatment initiation and end-of-treatment outcomes. METHODS: We performed an individual participant data meta-analysis of adults aged ≥18 years with RR-TB whose BMI was documented at treatment initiation. We compared odds of any unfavorable treatment outcome, mortality, or failure/recurrence between patients who were underweight (BMI <18.5 kg/m2) and not underweight. Adjusted odds ratios (aORs) and 95% confidence intervals (CIs) were estimated using logistic regression, with matching on demographic, clinical, and treatment-related factors. We evaluated effect modification by human immunodeficiency virus (HIV) status and other variables using likelihood ratio tests. We also estimated cumulative incidence of mortality during treatment stratified by HIV. RESULTS: Overall, 5148 patients were included; 1702 (33%) were underweight at treatment initiation. The median (interquartile range) age was 37 years (29 to 47), and 455 (9%) had HIV. Compared with nonunderweight patients, the aOR among underweight patients was 1.7 (95% CI, 1.4-1.9) for any unfavorable outcome, 3.1 (2.4-3.9) for death, and 1.6 (1.2-2.0) for failure/recurrence. Significant effect modification was found for World Health Organization region of treatment. Among HIV-negative patients, 24-month mortality was 14.8% (95% CI, 12.7%-17.3%) for underweight and 5.6% (4.5%-7.0%) for not underweight patients. Among patients with HIV, corresponding values were 33.0% (25.6%-42.6%) and 20.9% (14.1%-27.6%). CONCLUSIONS: Low BMI at treatment initiation for RR-TB is associated with increased odds of unfavorable treatment outcome, particularly mortality.

RESUMO

OBJECTIVES: Globally, drug-resistant tuberculosis (DR-TB) is the leading cause of death globally related to antimicrobial resistance, affecting 500,000 emergent cases annually. In 2018, the first United Nations High-Level Meeting (UNHLM) on tuberculosis declared DR-TB a global public health priority. Bold country targets were established for 2018-2022. This study reviews the DR-TB situation in 2018, and the UNHLM target accomplishments in 10 high-burden countries (HBCs). METHODS: An ecological descriptive analysis of the top 10 DR-TB HBCs (Bangladesh, China, India, Indonesia, Myanmar, Nigeria, Pakistan, Philippines, Russian Federation, and South Africa), which share 70% of the global DR-TB burden, was undertaken, complemented by a cascade-of-care analysis and a survey gathering additional information on key advances and setbacks 2 years after the UNHLM declaration. RESULTS: Most countries are showing historic advances and are on track for the 2018 and 2019 targets. However, according to the cascade-of-care, none of the countries are capable of providing effective care for 50% of the estimated patients. Increasing levels of fluoroquinolone resistance and access to timely susceptibility testing can jeopardize ongoing adoption of shorter, all-oral treatment regimens. The programmatic management of DR-TB in children remains minimal. Achievements for 2020 and beyond may be affected significantly by the coronavirus disease 2019 (COVID-19) pandemic. CONCLUSION: Triggered by the COVID-19 pandemic, there is a global risk of recoil in DR-TB care with long-term consequences in terms of deaths, suffering and wider transmission. Investment to support DR-TB services is more important now than ever to meet the aspirations of the UNHLM declaration.
