Mind the Gaps: Pharmacokinetic Research to Advance Pediatric HIV/TB Cotreatment and TB Prevention
Tuberculosis (TB) is the leading cause of death among children with HIV, yet insufficient data are available on the pharmacokinetics of newer HIV/TB cotreatment strategies in children. Current WHO-recommended rifampicin dosages result in low concentrations in most children, and high-dose rifampicin may improve outcomes and shorten treatment duration. Yet the impact of high-dose rifampicin on dolutegravir exposures has not been examined in children. This study aims to evaluate the safety and pharmacokinetics of dolutegravir twice daily among HIV/TB coinfected children receiving standard-dose and high-dose rifampicin.
