Objectives To assess in pregnant women with HIV the rates of amniocentesis and chorionic villus sampling ( CVS ), and the outcomes associated with such procedures. Design Observational study. Data from the Italian National Program on Surveillance on Antiretroviral Treatment in Pregnancy were used. Setting University and hospital clinics. Population Pregnant women with HIV . Methods Temporal trends were analysed by analysis of variance and by the Chi‐square test for trend. Quantitative variables were compared by Student's t ‐test and categorical data by the Chi‐square test, with odds ratios and 95% confidence intervals calculated. Main outcome measures Rate of invasive testing, intrauterine death, HIV transmission. Results Between 2001 and 2015, among 2065 pregnancies in women with HIV , 113 (5.5%) had invasive tests performed. The procedures were conducted under antiretroviral treatment in 99 cases (87.6%), with a significant increase over time in the proportion of tests performed under highly active antiretroviral therapy ( HAART ) (100% in 2011–2015). Three intrauterine deaths were observed (2.6%), and 14 pregnancies were terminated because of fetal anomalies. Among 96 live newborns, eight had no information available on HIV status. Among the remaining 88 cases with either amniocentesis ( n = 75), CVS ( n = 12), or both ( n = 1), two HIV transmissions occurred (2.3%). No HIV transmission occurred among the women who were on HAART at the time of invasive testing, and none after 2005. Conclusions The findings reinforce the assumption that invasive prenatal testing does not increase the risk of HIV vertical transmission among pregnant women under suppressive antiretroviral treatment. Tweetable abstract No HIV transmission occurred among women who underwent amniocentesis or CVS under effective anti‐ HIV regimens.
