Abstract

Background The current global and national indications for antiretroviral treatment (ART, usually triple combination therapy) in adolescent and adults, including pregnant women, recommend early ART before immunologic decline, pre-exposure chemoprophylaxis (PrEP), and treatment of HIV-negative partners in serodiscordant couples. There is limited information on the implementation of these recommendations among pregnant women with HIV and their partners. Methods The present analysis was performed in 2016, using data from clinical records of pregnant women with HIV, followed between 2001 and 2015 at hospital or university clinics within a large, nationally representative Italian cohort study. The study period was divided in three intervals of five years each (2001-2005, 2006-2010, 2011-2015), and the analysis evaluated temporal trends in rates of HIV diagnosis in pregnancy, maternal antiretroviral treatment at conception, prevalence of HIV infection among partners of pregnant women with HIV, and proportion of seronegative and seropositive male partners receiving antiretroviral treatment. Results The analysis included 2755 pregnancies in women with HIV. During the three time intervals considered the rate of HIV diagnosis in pregnancy (overall 23.3%), and the distribution of HIV status among male partners (overall 48.7% HIV- negative, 28.6% HIV-positive and 22.8% unknown) remained substantially unchanged. Significant increases were observed in the proportion of women with HIV diagnosed before pregnancy who were on antiretroviral treatment at conception (from 62.0% in 2001-2005 to 81.3% in 2011-2015, P < 0.001), and in the proportion of HIV-positive partners on antiretroviral treatment (from 73.3% in 2001-2005 to 95.8% in 2011-2015, P = 0.002). Antiretroviral treatment was administered in 99.1% of the pregnancies that did not end early because of miscarriage, termination, or intrauterine death, and in 75.3% of those not ending in a live birth. No implementation of antiretroviral treatment was introduced among male HIV-negative partners. Conclusions The results suggest good implementation of antiretroviral treatment among HIV-positive women and their HIV-positive partners, but no implementation, even in recent years, of Pre-Exposure Prophylaxis (PrEP) among uninfected male partners. Further studies should assess the determinants of this occurrence and clarify the attitudes and the potential barriers to PrEP use.
