Topic Collection: Implementation and Scale-up of Tuberculosis Preventive Treatment

Implementation and Scale-up of Tuberculosis Preventive Treatment

Tuberculosis is the top infectious disease globally, driven by transmission and progression from latent to infectious disease. The WHO urges closing diagnostic gaps and expanding TB preventive treatment (TPT) to reduce its burden.  TPT remains underused worldwide, notably among household contacts, despite its effectiveness. Enhancing TPT implementation is crucial for disease elimination.  This Topic Collection seeks to highlight recent advancements in TPT, particularly among high-burden countries and household contacts, welcoming diverse research approaches. Submissions Open | Submission Deadline: 12th August 2024

Tuberculosis is the leading cause of death due to a single infectious disease globally. Its persistence is driven by ongoing transmission of tuberculosis from people with infectious tuberculosis disease and by progression of (latent) tuberculosis infection to infectious tuberculosis disease. The WHO has called on countries to prioritize closing diagnostic gaps in tuberculosis detection and treatment and scale-up treatment of tuberculosis infection—so called, tuberculosis preventive treatment (TPT)—to help reduce the tuberculosis burden and mitigate the morbidity and mortality it causes. Yet, TPT remains severely underutilized globally. While implementation and scale-up has been successful among people living with HIV, a group at high-risk for tuberculosis disease, it has been poor among household contacts of people with tuberculosis disease—another group at very high-risk for tuberculosis disease who number >40 million annually. Between 2018 and 2022, less than 3 million household contacts received TPT—an intervention that can reduce TB disease risk by 70-90%. Improving the implementation and scale up of TPT is essential to eliminating this disease. The Topic Collection will cover recent advances in TPT implementation and scale-up, particularly those conducted in high tuberculosis burden countries and those focused on household contacts. The methodological scope of submissions is broad, and we welcome original research articles utilizing qualitative approaches, implementation science, modelling and economic evaluation, and evidence synthesis (e.g., meta-analysis), as well as cohort studies and clinical trials. Topics that would be of great interest:
  • The cost-effectiveness and budget impact of TPT scale-up
  • Feasibility and acceptability of approaches to implement and scale-up TPT, particularly those in primary care
  • Qualitative research highlighting barriers and facilitators to TPT implementation and scale-up among patients, providers, and policy-makers
  • Mixed-methods research leveraging before-and-after designs to evaluate the impact of interventions to implement and/or scale-up TPT
  • Cluster randomized trials or prospective studies evaluating interventions that can impact TPT uptake
