Etiopathogenesis and epidemiology

Prenatal HIV screening

Vertical transmission

Antepartum care

  • HIV RNA viral load at initial visit, every 2-4 weeks after initiation or change of therapy, monthly until undetectable, then every 3 months.
  • CD4 cell count every 3-6 months
  • Resistance testing if not previously performed
  • ART initiation as early as possible
  • Avoid amniocentesis unless viral load ?1,000 copies/mL

Delivery planning

  • Avoid artificial ROM (rupture of membranes), fetal scalp electrode, operative vaginal delivery.
  • Viral load ?1,000 copies/mL: ART + vaginal delivery
  • Viral load >1,000 copies/mL: ART + zidovudine + cesarean delivery
  • Reducing perinatal HIV transmission
    • Cesarean delivery: ~50% when viral load is >1,000 copies/mL

Postpartum care

  • Mother: continue ART
  • Infant
    • Maternal viral load ?1,000 copies/mL: zidovudine
    • Maternal viral load >1,000 copies/mL: multidrug ART
