A new tuberculosis vaccine is a high priority. However, the classical development pathway is a major deterrent. Most tuberculosis cases arise within 2 years after Mycobacterium tuberculosis exposure, suggesting a 3-year trial period should be possible if sample size is large to maximize the number of early exposures.

Digital adherence technologies (DATs) have emerged as an alternative to directly observed therapy (DOT) for supervisions of tuberculosis (TB) treatment. We conducted a meta-analysis of implementation feedback obtained from people with TB and health care workers (HCWs) involved in TB REACH Wave 6-funded DAT evaluation projects. Projects administered standardized post-implementation surveys based on the Capability, Opportunity, Motivation, Behavior (COM-B) model to people with TB and their health care workers.

Article Synopsis
  • QuantiFERON-TB-Gold-in-tube (QFT-GIT) and QuantiFERON-TB Gold-Plus (QFT-Plus) are tests used to diagnose latent tuberculosis infection, with the latter designed to improve accuracy by including an extra antigen tube.
  • A study was conducted on HIV-negative goldminers in South Africa to compare the effectiveness of these two tests, finding that there was a 94.7% agreement between the results from QFT-Plus and QFT-GIT.
  • The research also indicated a noteworthy difference in test results based on the participants' body mass index (BMI), which could inform future assessments of TB infection risk.

Impact and cost-effectiveness of short-course tuberculosis preventive treatment for household contacts and people with HIV in 29 high-incidence countries: a modelling analysis.

Lancet Glob Health

August 2023

Center for Tuberculosis Research, Division of Infectious Diseases, Johns Hopkins University School of Medicine, Baltimore, MD, USA; Department of Epidemiology, Johns Hopkins Bloomberg School of Public Health, Baltimore, MD, USA.

Background: Guidelines and implementation of tuberculosis preventive treatment (TPT) vary by age and HIV status. Specifically, TPT is strongly recommended for people living with HIV/AIDS (PLWHA) and household contacts younger than 5 years but only conditionally recommended for older contacts. Cost remains a major barrier to implementation.

Retention of antiretroviral (ART) patients is a priority for achieving HIV epidemic control in South Africa. While machine-learning methods are being increasingly utilised to identify high risk populations for suboptimal HIV service utilisation, they are limited in terms of explaining relationships between predictors. To further understand these relationships, we implemented machine learning methods optimised for predictive power and traditional statistical methods.

Background: Identification of proinflammatory factors responding to Mycobacterium tuberculosis is important to reduce long-term sequelae of pulmonary tuberculosis (TB).

Methods: We examined the association between plasma biomarkers, the fraction of exhaled nitric oxide (FeNO), and lung function among a prospective cohort of 105 adults newly diagnosed with TB/human immunodeficiency virus (HIV) in South Africa. Participants were followed for 48 weeks from antiretroviral therapy (ART) initiation with serial assessments of plasma biomarkers, FeNO, lung function, and respiratory symptoms.

Introduction: The rising global burden of metabolic disease impacts the control of endemic tuberculosis (TB) in many regions, as persons with diabetes mellitus (DM) are up to three times more likely to develop active TB than those without DM. Active TB can also promote glucose intolerance during both acute infection and over a longer term, potentially driven by aspects of the immune response. Identifying patients likely to have persistent hyperglycemia following TB treatment would enable closer monitoring and care, and an improved understanding of underlying immunometabolic dysregulation.

Background: Tuberculosis infection (TBI) and TB disease (TBD) incidence remains poorly described following household contact (HHC) rifampin-/multidrug-resistant TB exposure. We sought to characterize TBI and TBD incidence at 1 year in HHCs and to evaluate TB preventive treatment (TPT) use in high-risk groups.

Methods: We previously conducted a cross-sectional study of HHCs with rifampin-/multidrug-resistant TB in 8 high-burden countries and reassessed TBI (interferon-gamma release assay, HHCs aged ≥5 years) and TBD (HHCs all ages) at 1 year.

Article Synopsis
  • A randomized controlled trial (RCT) in South Africa tested a two-way texting (2wT) intervention for follow-up after voluntary medical male circumcision (VMMC) to assess its effectiveness and safety compared to routine care.
  • The study found that 2wT participants had a similar rate of adverse events (AEs) as the control group, indicating that 2wT is not less effective in tracking AEs and could ease the workload for healthcare workers.
  • With 1084 men enrolled, the results showed noninferiority of 2wT, revealing that it could be a viable alternative for monitoring post-operative care in both rural and urban areas.

Introduction: Despite advances in HIV and HIV co-morbidity service delivery, substantial challenges remain in translating evidence-based interventions into routine practice to bring optimal care and prevention to all populations. While barriers to successful implementation are often multifactorial, healthcare worker behaviour is critical for on-the-ground and in-clinic service delivery. Implementation science offers a systematic approach to understanding service delivery, including approaches to overcoming delivery gaps.
