HIV in Infants and ChildrenQuestion 6/10

A 10-week-old infant is seen in the clinic to start antiretroviral therapy. Due to unknown maternal HIV status and a precipitous delivery, the mother did not receive any intrapartum antiretroviral medications for the prevention of mother-to-child HIV transmission. In the postpartum period, the infant took a 3-drug antiretroviral postexposure prophylaxis regimen for 6 weeks. An HIV DNA PCR was positive at birth, negative at 2 weeks and 5 weeks (while receiving antiretroviral therapy), but positive at 8 and 9 weeks of age. Additional laboratory studies show an HIV RNA level of 92,305 copies/mL and a CD4 count of 1,034 cells/mm³. The infant weighs 4.9 kg. A baseline HLA B*5701 test is negative.

According to the Pediatric ART Guidelines, which one of the following is considered a preferred initial antiretroviral regimen for this 10-week-old infant?

Efavirenz plus tenofovir DF plus emtricitabine

Raltegravir plus tenofovir DF plus emtricitabine

Lopinavir-ritonavir plus abacavir plus lamivudine

Dolutegravir plus abacavir plus lamivudine

Table 1. HHS Guidelines for the Use of Antiretroviral Agents in Pediatric HIV Infection

Initial Antiretroviral Regimens for Infants from Birth to <30 Days of Age^a,b
Age	Regimens	Age/Weight Restrictions^c
Preferred Initial Regimens Based on Age and Weight at Time of Treatment Initiation
Infants ≥37 weeks of gestation and aged <30 days and Preterm infants with a postmenstrual age of ≥37 weeks at treatment initiation	NNRTI (Nevirapine) or INSTI (Raltegravir) plus two NRTIs
	Nevirapine plus zidovudine plus (lamivudine or emtricitabine)	None
	Ralegravir plus zidovudine plus (lamivudine or emtricitabine)	≥2 kg
Preterm infants ≥32 to <37 weeks of gestation	NNRTI (Nevirapine) plus two NRTIs
	Nevirapine plus zidovudine plus (lamivudine or emtricitabine)	None
Preterm infants <32 weeks of gestation	Consultation with a pediatric HIV expert or the National Perinatal HIV/AIDS Hotline (1-888-448-8765) is recommended
Alternative Initial Regimens Based on Age and Weight at Time of Treatment Initiation
Postmenstrual age ≥42 weeks and Postnatal age of >14 days	PI (Lopinavir-ritonavir) plus two NRTIs
	Lopinavir-ritonavir plus zidovudine plus (lamivudine or emtricitabine)	None
Alternative NRTI Backbone Based on Age and Weight at Time of Treatment Initiation
Infants ≥37 weeks of gestation	Abacavir plus (lamivudine or emtricitabine) if HLA-B*5701 negative^d	None
^aPanel recommendations summarized in this table are for children with HIV-1 infection. ^b Recommendations for antiretroviral drugs or antiretroviral therapy regimens to be used in special circumstances are addressed in the pediatric antiretroviral therapy guidelines (e.g., ARV resistance, HBV coinfection). ^c Fixed dose combinations may be available for some medication combinations. ^d Abacavir is not approved by the U.S. Food and Drug Administration (FDA) for use in full-term neonates and infants aged <3 months. Recent data from the IMPAACT P1106 trial and two observational cohorts provide reassuring data on the safety of ABC in infants when initiated at the age of <3 months. Before abacavir administration, a negative HLA-B*5701 allele test result should be available.
