Neftaly BHIVA guidelines on the management of HIV in pregnancy and postpartum

Sure! Here’s a summary of the BHIVA (British HIV Association) guidelines on the management of HIV in pregnancy and postpartum, incorporating key points relevant for clinical practice. These guidelines are well-respected internationally and are updated regularly.
BHIVA Guidelines on Management of HIV in Pregnancy and Postpartum
1. Preconception and Antenatal Care
- Preconception counseling: Women with HIV should receive counseling about family planning, conception options, and importance of viral suppression before pregnancy.
- Early antenatal booking: Women with HIV should be booked early in pregnancy to optimize care and start interventions promptly.
- Baseline investigations: Include CD4 count, HIV viral load, genotypic resistance testing (if indicated), and screening for other infections (HBV, HCV, STIs, etc.).
- ART initiation: Start or continue combination antiretroviral therapy (cART) as soon as pregnancy is confirmed or ideally before conception.
- Viral suppression goal: Aim for undetectable plasma viral load (<50 copies/mL) by 36 weeks gestation to minimize vertical transmission risk.
2. Antiretroviral Therapy (ART)
- Use regimens with proven safety in pregnancy — typically, two NRTIs plus either an integrase inhibitor (e.g., dolutegravir) or a boosted protease inhibitor.
- Avoid drugs with known teratogenic risks or limited safety data unless benefits outweigh risks.
- Monitor adherence and side effects closely throughout pregnancy.
3. Monitoring During Pregnancy
- Viral load testing every 4 weeks until suppressed, then every 8-12 weeks.
- CD4 count every trimester or as clinically indicated.
- Regular obstetric monitoring per standard pregnancy guidelines.
- Monitor for drug toxicity (e.g., renal function, liver function).
4. Delivery
- Mode of delivery depends on viral load near delivery:
- If viral load <50 copies/mL near delivery: Vaginal delivery is recommended.
- If viral load >50 copies/mL near delivery: Consider elective cesarean section to reduce transmission risk.
- Intravenous zidovudine may be administered during labor if viral load is not fully suppressed.
5. Infant Management
- Post-exposure prophylaxis (PEP): Neonates receive antiretroviral prophylaxis, usually zidovudine alone if maternal viral load is suppressed, or combination therapy if higher risk.
- Infant HIV testing: PCR testing at birth, 6 weeks, and at regular intervals up to 18 months.
- Avoid breastfeeding in settings where safe formula feeding is available (in UK and similar contexts). WHO guidelines differ for low-resource settings.
6. Postpartum Care
- Continue maternal ART postpartum.
- Monitor maternal viral load and adherence regularly.
- Provide contraception counseling and support.
- Infant HIV testing follow-up and pediatric HIV care if needed.
- Support mental health and address social factors.
Key Points Summary:
- Aim for viral suppression <50 copies/mL by 36 weeks.
- Start or continue effective ART during pregnancy.
- Mode of delivery based on viral load.
- Neonatal ART prophylaxis tailored to risk.
- Avoid breastfeeding where safe alternatives exist.
- Close maternal and infant follow-up postpartum.
