Acceptability of HCV screening and potential use of DAAs during pregnancy in women attending antenatal care in Egypt, Pakistan and Ukraine

Background: The risk of vertical transmission of hepatitis C virus (HCV) is ≈6%, and evidence suggests HCV negatively affects pregnancy and infant outcomes. Despite this, universal antenatal HCV screening is not available in most settings, and direct acting antivirals (DAA) are yet to be approved for use in pregnancy or breastfeeding period. Larger safety and efficacy trials are needed. At current there is limited understanding of the acceptability of routine HCV screening and use of DAAs in pregnancy but only among women in high HCV burden countries. Methods: We conducted a cross-sectional survey of pregnant or post-partum (<6 months since delivery) women attending antenatal clinics or maternity hospitals in Egypt, Pakistan and Ukraine. In Ukraine, this included one HIV clinic. Acceptability of free universal antenatal HCV screening and potential uptake of DAA treatment in the scenario of DAAs being approved for use in pregnancy was assessed. Results were stratified by HCV status and in Ukraine by HIV status. Descriptive statistics were used to explore differences in acceptability of treatment in pregnancy by country. Findings: Among 630 women (n=210 per country) who participated, the median age was 30 [interquartile range (IQR) 26, 34] years, 73% were pregnant and 27% postpartum, and 27% ever HCV antibody or PCR positive. 40% of women in Ukraine were living with HIV. Overall 93% of women supported free universal HCV screening in pregnancy, with no difference by country. 88% would take DAAs in pregnancy if approved for use: 92%, 98% and 73% among women in Egypt, Pakistan and Ukraine, respectively. Motivation for use of DAAs in pregnancy (to avert vertical transmission or for maternal HCV cure) varied by country, HCV status and HIV status (in Ukraine). No predictors for acceptability of DAAs were identified. Interpretation: Our survey across 3 high burden countries found very high acceptability of free universal HCV screening and DAAs if approved for use in pregnancy. Clinical trials to evaluate the safety and efficacy of DAAs during pregnancy and breastfeeding are urgently required.
