TB Stigma in the UK: Patients Experiences and Everyday Responses

Public understanding of tuberculosis (TB) is shaped by sociocultural norms, educational background, and personal experiences. Misconceptions about TB transmission, disease severity, and treatment side effects are widespread, contributing to stigma and fear of social rejection. Such stigma can lead individuals to conceal their diagnosis, limiting access to support, engagement with healthcare, and overall health literacy. TB-related stigma is recognised as a significant barrier to ending the global TB epidemic, affecting quality of life and access to care. Yet in high-income, low-incidence (HILI) countries like the UK, its prevalence, influence, and lived impact remain largely unexplored. Where stigma appears in research, it is often treated as an emerging theme, leaving a critical gap in understanding how individuals with TB, or those caring or supporting them, experience and respond to it. This study adopts a Constructivist Grounded Theory (CGT) approach to examine TB-related stigma in depth. CGT allows the research to explore how people living with TB make sense of, interpret, negotiate, and resist stigma, capturing the dynamic and contextual ways it shapes their lives, identities, and interactions with healthcare systems. By investigating these meaning-making processes, the study aims to illuminate how stigma operates in the UK, providing insights to inform future stigma-reduction interventions, communication strategies, and supportive healthcare practices, ultimately benefiting patients, communities, and the NHS.

Parent Study Name: Pulmonary Rehabilitation to Reduce Post-Tuberculosis Morbidity (TB Pure)

Individual-level, unblinded randomized controlled trial of an 8-week (short arm) or 24-week (extended arm) pulmonary rehabilitation program, relative to standard of care, to prevent post-tuberculosis respiratory morbidity. Randomization will occur in a 1:1:1 ratio at the initiation of treatment.

Leveraging mHealth to Enable and Adapt CHW Strategies to Improve TB/HIV Patient Outcomes in SA

mHealth solutions designed to support affordable human resources for health, such as community health workers (CHWs), offer the opportunity to reimagine a patient-centered, system-level solution that may radically change care models in low resource settings. The 'leap' of m-health is most potent and practical in settings where desktop-based infrastructure is lacking and hard-wired internet connectivity is unavailable. Investigators have demonstrated the feasibility of mHealth and human resource solutions in South Africa and shown marked improvements in screening, linkage and treatment initiation as well as supporting patient adherence through video DOT (vDOT) and early identification of treatment related toxicity. Investigators' strategies have evaluated solutions for individual cascade steps through TB and HIV smartphone and tablet-based m-health applications implemented by a CHW. This study combines these individual cascade step approaches into an innovative TB/HIV cascade intervention study entitled, "Leveraging mHealth to enable and adapt community health worker strategies to improve TB/HIV patient outcomes in South Africa (LEAP-TB-SA) Trial."

Pharmacokinetic Study of Sudapyridine（WX-081）in Healthy Chinese Subjects

This single-center, open-label, non-randomized study aims to evaluate the pharmacokinetics, mass balance, and metabolic pathways of WX-081 (Sudapyridine) following a single oral dose of \[U-14C\] WX-081 in healthy Chinese male volunteers. A total of 6-10 subjects will be enrolled to obtain complete samples and data from at least six participants. Biological samples, including blood, plasma, urine, and feces, will be collected over a specified time period. The study will assess pharmacokinetic parameters, excretion pathways, and identify major metabolites contributing to over 10% of plasma exposure.
