Therapeutic drug Monitoring Guided Raltegravir Dosing for Prevention of Vertical Transmission in a Premature Neonate Born to a Woman Living with Perinatally Acquired HIV

Abstract

We report a case of therapeutic drug monitoring guided raltegravir use for the prevention of vertical HIV transmission in a premature neonate born to a woman living with perinatally acquired HIV and documented resistance to multiple HIV drugs. Maternal viral load was above 1,000 copies/ml at delivery. This case demonstrates delayed raltegravir elimination in a neonate born at 33 weeks gestational age and a need for less frequent raltegravir dosing than is used in older infants and children.
