Adherence to antiretroviral therapy in pregnancy

Successful interventions to prevent congenital HIV require adherence to highly active antiretroviral therapy (HAART) in pregnancy from mothers and agreement with other interventions including mode of delivery and infant testing. We sought to audit adherence support offered antenatally, adherence with HAART, recommendations for delivery and infant testing in women receiving HIV care at our unit and delivering a child in 2004 and 2005. Of the 32 women identified, an adherence discussion was conducted when commencing therapy in 87% and subsequent visits in 77%. Five women were non-adherent with HAART, one disagreed with recommendations for delivery, and attendance at initial post-natal tests was documented in 61%. In general, the British HIV Association guidelines with regard to adherence are followed. Although numbers in this cohort are small, age, ethnicity and pre-pregnancy HIV diagnosis did not seem to affect adherence, but being therapy naïve and poor adherence may predict non-attendance at infant follow-up.
