Guidelines
Screening
All pregnant women should be offered HIV screening at booking visit (8-12 weeks).
Management
Antepartum Management
Antiretroviral Therapy (ART)
ALL women on an effective ART regimen who get pregnant should continue their ART treatment.
If the patient not on ART → should start ART as soon as possible (by 24 weeks the very latest)
- 1st choice regimen: tenofovir DX/emtricitabine + dolutegravir (if no renal or bone concerns)
Monitoring
- CD4 count at baseline + each trimester + at delivery
- Viral load 2-4 weeks after starting ART + every trimester + at 36 weeks + at delivery
- LFTs with routine blood
Intrapartum Management
Measure plasma viral load at 36 weeks and use that measurement to decide the mode of delivery.
- If viral load <50 copies/mL → vaginal delivery can be supported
- If viral load >50 copies/mL →
- Planned (pre-labour) caesarean section to be considered from 38 weeks
- Zidovudine infusion throughout labour and/or delivery until cord clamping
- Should be commenced 4 hours prior to planned Caesarean section
The women must deliver in a unit with on-site paediatric care to start neonatal PNP within 4 hr.
Postpartum Management
Mother

Choice of PNP depends on the risk of acquiring HIV, low-risk features:
- All viral load measurements 10 weeks prior delivery are <50 copies/mL
- Maternal ART commenced at least 10 weeks prior delivery
- At least 1 viral load measurement 6 weeks prior delivery
- Good engagement from mother's end
Low Risk Baby (all the above met)
Offer zidovudine monotherapy for 2 weeks
High Risk Baby (any of the above not met) (esp. viral load >50 copies/mL)
