In 1989, one in four (25%) infants born to women living with HIV were infected; by the age of 2 years, there was 25% mortality among them due to HIV. These and other pieces of data prompted the development of interventions to offset vertical transmission, including the landmark Pediatric AIDS Clinical Trial Group Study (PACTG 076) in 1994. This study reported a 67.5% reduction in perinatal HIV transmission with prophylactic antenatal, intrapartum, and postnatal zidovudine. Numerous studies since then have provided compelling evidence to further optimize interventions, such that annual transmission rates of 0% are now reported by many health departments in the US and elimination has been validated in several countries around the world. Despite this success, the elimination of HIV’s vertical transmission on the global scale remains a work in progress, limited by socioeconomic factors such as the prohibitive cost of antiretrovirals. Here, we review some of the key trials underpinning the development of guidelines in the US as well as globally, and discuss the evidence through a historic lens.

Objectives:The objectives of this study was to describe variation in induction regimen, identify predictors of induction immunosuppression (IS) choice, and examine the impact of induction IS regimen on length of stay (LOS) and total perioperative costs in pediatric liver transplant recipients. Methods: We analyzed liver transplant utilization data in the Pediatric Health Information System database. Patients were divided into 3 induction IS groups: (1) steroids only, (2) T-cell depleting antibody (TDA), and (3) non-TDA. We identified predictors of induction IS regimen and examined associations between each outcome and choice of induction IS. Results: We analyzed 4905 liver transplant recipients (50% female, 80% under age 13 years, 42% non-Hispanic White). Most patients (3162, 64%) received steroids only induction, and about twice as many patients received a non-TDA regimen (1093, 22%) versus a TDA regimen (650, 13%). Median total perioperative costs were highest for the TDA group
