Exclusive breastfeeding (EBF)• Advised up to 6 months of age• Beneficial for all children (exposed and

unexposed)• Cuts mother-to-child transmission to half• Promotion must be carried out in the general

population– would fail if only promoted among HIV+

women

Conclusions• Peer-counselling for EBF increases EBF

rates at 3 months 2-fold depending on the local context

• Large country differences in – Baseline characteristics– Baseline EBF rates– South Africa is a case of its own

(Nor B, et al. J Hum Lact 2009)

Post-hoc reflections

• Complementary feeding needs to be included• Individual or group counselling? Home-based or

facility-based?• BF alone or combined with other interventions?• Focus on early BF and initiation

– Most important to be exclusive in the beginning• Golden opportunity for closer integration

between HIV-care and maternal, newborn and child care

PROMISE PEP (ANRS 12174)

• BF advice is not enough to protect the child• A randomised controlled trial comparing the

efficacy of infant peri-exposure prophylaxis with lopinavir/ritonavir (LPV/r) versus lamivudine to prevent HIV-1 transmission by breastfeeding

• Clinicaltrials.gov registration # NCT00640263
