Article Synopsis
  • The World Health Organization recommends the use of single-dose rifampicin (SDR) for leprosy post-exposure prophylaxis (PEP), potentially reducing leprosy risk by about 50% in contacts of patients.
  • A Phase 2 trial tested a new PEP regimen that combines bedaquiline with rifampicin (BE-PEP) against the standard therapy (SDR-PEP), focusing on safety and QT interval changes in patients.
  • The trial, involving 313 participants, demonstrated that BE-PEP did not significantly differ from SDR-PEP regarding QT interval changes after treatment, indicating comparable safety profiles between the two regimens.

Article Synopsis
  • - Anti-mycobacterial drugs can cause QT interval prolongation, risking serious heart issues, but monitoring is tough in places with high rates of leprosy and tuberculosis.
  • - The BE-PEOPLE trial assessed the safety of a bedaquiline regimen while measuring QT intervals before and after treatment using both mobile electrocardiogram (mECG) and standard methods.
  • - Results showed that mECG is a feasible and accurate tool for QT interval tracking, with a strong correlation to traditional measurements, although automated readings were generally less precise.

Background: Expansion of antimicrobial resistance monitoring and epidemiological surveillance are key components of the WHO strategy towards zero leprosy. The inability to grow Mycobacterium leprae in vitro precludes routine phenotypic drug susceptibility testing, and only limited molecular tests are available. We evaluated a culture-free targeted deep sequencing assay, for mycobacterial identification, genotyping based on 18 canonical SNPs and 11 core variable-number tandem-repeat (VNTR) markers, and detection of rifampicin, dapsone and fluoroquinolone resistance-associated mutations in rpoB/ctpC/ctpI, folP1, gyrA/gyrB, respectively, and hypermutation-associated mutations in nth.

Background: Leprosy is an ancient infectious disease with an annual global incidence of around 200,000 over the past decade. Since 2018, the World Health Organization (WHO) recommends single-dose rifampicin as post-exposure prophylaxis (SDR-PEP) for contacts of leprosy patients. The Post ExpOsure Prophylaxis for Leprosy (PEOPLE) trial evaluated PEP with a double dose of rifampicin in Comoros and Madagascar.
