Achieving rapid reduction of HIV-1 viral load in HIV-positive pregnant women close to term – an obstetric/medical emergency: a review of three cases

Abstract

Summary Mother-to-child transmission (MTCT) of HIV infection is now uncommon in the UK and the management of HIV-positive pregnant women is usually relatively straightforward. However, HIV viral load suppression may be difficult to achieve peripartum for women who book very late in pregnancy and those with a poor adherence to antiretroviral therapy (ART). These pregnancies are at a higher risk of MTCT due to high viral load (VL). Therefore, the development of interventions to achieve a rapid reduction of HIV VL is essential. We describe three relevant cases that presented to our unit over a 12-month period and discuss the strategies employed to manage these challenging cases. All babies were born healthy and were HIV proviral DNA-negative at 12 weeks postpartum. No serious adverse events were reported for the mothers or their babies.
