Exposure to dolutegravir in pregnant women living with HIV in Central and Eastern Europe and neignboring countries - data from the ECEE Network Group

Objectives:The purpose of this study was to investigate dolutegravir (DTG) use among women and exposure to DTG during pregnancy in real world in Central and Eastern Europe and neighboring countries. Material and methods: Centres from 20 countries included in the Euroguidelines in Central and Eastern Europe (ECEE) Network and Finland were asked to complete an on-line questionnaire. Results: Seven centres from Czech Republic, Finland, Greece, Poland, Slovakia, and Turkey provided detailed information. DTG exposure was reported in 415 women, of which 26 were during pregnancy. Of those, 22 were on DTG at the time of conception and 4 had started DTG during pregnancy. Few women had conventional risk factors.The data on folic acid usage was unknown for eight women; 14 were using and four were not using folic acid. Four pregnancies were ongoing at the time of the study and of those with an outcome, 77.3% resulted with term, 13.6% preterm delivery, 4.5% spontaneous and 4.5% medical abortion. Conclusions:The DTG signal report indicates the importance of safety research for drug use in pregnancy and highlights the urgent need for systematic surveillance of pregnancy outcomes and neonatal surveillance. Countries with low- or moderate HIV prevalence should be included in studies reviewing pregnancy outcomes and in any surveillance system to ensure the accuracy of drug safety revision.
