Ritonavir-boosted atazanavir (ATV/r) and rifampicin are mainstays of second-line antiretroviral and multiple anti-TB regimens, respectively. Rifampicin induces CYP3A4, a major enzyme involved in atazanavir metabolism, causing a drug-drug interaction (DDI) which might be exaggerated in pregnancy. Having demonstrated that increasing the dose of ATV/r from once daily (OD) to twice daily (BD) in non-pregnant adults can safely overcome this DDI, we developed a pregnancy physiologically based pharmacokinetic (PBPK) model to explore the impact of pregnancy.

Article Synopsis
  • Invasive meningococcal disease (IMD) is mainly caused by five Neisseria meningitidis serogroups (A/B/C/W/Y), leading to high morbidity and mortality, especially in certain age groups.
  • Polysaccharide conjugate vaccines can produce strong immune responses and lower disease transmission, highlighting the importance of tailored vaccination programs based on local prevalence and epidemiology.
  • Recent trends show that while serogroup A has declined due to vaccination, other serogroups like B, C, W, and Y have varied impacts, and IMD has resurged during the pandemic, particularly affecting unvaccinated individuals.
