Objective: To assess sex, age, regional differences, and the changing trend in human immunodeficiency virus and tuberculosis (HIV-TB) in different regions from 1990 to 2021, and project future trends.

Methods: Global Burden of Disease Study 2021 data were analyzed to assess HIV-TB incidence, death, prevalence, and DALY rates from 1990 to 2021, including different types of TB co-infections (drug-susceptible, multidrug-resistant, and extensively drug-resistant). Bayesian age-period-cohort models were used to forecast age-standardized DALY rates through 2035.

Background: As a result of shared social and structural risk factors, people in households affected by tuberculosis may have an increased risk of chronic conditions; at the same time, tuberculosis screening may be an opportunity for interventions. We sought to describe the prevalence of HIV, nutritional disorders, and noncommunicable diseases (NCDs) among members of tuberculosis-affected households in 3 African countries.

Methods And Findings: A part of a multicountry cohort study, we screened for tuberculosis, HIV, nutritional disorders (underweight, anaemia, overweight/obesity), and NCDs (diabetes, hypertension, and chronic lung disease) among members of tuberculosis-affected households aged ≥10 years in Mozambique, Tanzania, and Zimbabwe.

Article Synopsis
  • * Utilizing data from the Global Burden of Disease Study 2021, the research analyzed trends in incidence, prevalence, mortality, and disability-adjusted life years (DALYs) for various forms of HIV-related TB from 1990 to 2021.
  • * In 2021, the rates showed that HIV-DS-TB had the highest incidence and mortality rates compared to HIV-MDR-TB and HIV-XDR-TB, with significant increases in the incidence and mortality of multi-drug resistant and extensively drug-resistant forms over the study

Article Synopsis
  • Chronic immune activation in HIV/TB co-infection increases the risk of TB reactivation, highlighting the need for therapies that target immune responses.
  • The IDO inhibitor D-1 methyl tryptophan (D1MT) shows promise in improving immune function in the lungs and enhancing TB control without affecting HIV treatment.
  • Further trials are recommended to investigate the effectiveness of IDO inhibition as a host-directed therapy in individuals co-infected with M. tuberculosis and HIV while on antiretroviral therapy.

Article Synopsis
  • The study examines tuberculosis cure rates in Brazil from 2001 to 2022, revealing that most regions show a significant decline in these rates, particularly towards the end of the analyzed period.
  • The research utilized regression models to analyze data on pulmonary tuberculosis, those with tuberculosis-HIV co-infection, and individuals undergoing retreatment, finding an average annual decrease in cure rates across all groups.
  • The results highlight a troubling trend that contradicts existing public health policies, indicating an urgent need for improved patient follow-up and treatment strategies to address these declining cure rates.
