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{\textquoteright}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.
