Methods: We administered monthly ADR questionnaires to participants with TB in Worcester, South Africa.

Article Synopsis
  • The COVID-19 pandemic significantly disrupted tuberculosis (TB) treatment, particularly impacting directly observed therapy (DOT) adherence programs in South Africa.
  • Data from a study comparing DOT adherence rates before (pre-COVID-19) and after (post-COVID-19 lockdown) revealed marked increases in non-adherence rates, with the highest non-adherence observed immediately after the first lockdown.
  • The findings suggest that the negative impact on DOT adherence persisted post-lockdown, highlighting the need for further investigation into the barriers that worsened treatment adherence during and after the pandemic.

Background: In South Africa, an estimated 11% of the population have high alcohol use, a major risk factor for TB. Alcohol and other substance use are also associated with poor treatment response, with a potential mechanism being altered TB drug pharmacokinetics.

Objectives: To investigate the impact of alcohol and illicit substance use on the pharmacokinetics of first-line TB drugs in participants with pulmonary TB.
