Reliability of Risk-Based Screening for Hepatitis C Virus Infection among Pregnant Women in Egypt

Objectives: The Centers for Disease Control and Prevention (CDC) only recommends risk-based HCV screening for pregnant women in the United States. This study sought to determine the reliability of risk-based versus universal HCV screening for pregnant women in Egypt, a country with the world's highest HCV prevalence that also relies on risk-based screening, and to identify additional characteristics that could increase the reliability of risk-based screening.Methods: Pregnant women attending the Cairo University antenatal clinic were tested for anti-HCV antibodies and RNA, and demographic characteristics and risk factors for infection were assessed.Results: All 1250 pregnant women approached agreed to participate (100%) with a mean age of 27.4 +/- 5.5 years (range: 16-45). HCV antibodies and RNA were positive in 52 (4.2%) and 30 (2.4%) women respectively. After adjustment, only age (OR: 1.08, 95% CI: 1.002-1.16, p < 0.01), history of prior pregnancies (OR: 1.20, 95% CI: 1.01-1.43, p < 0.04), and working in the healthcare sector (OR: 8.68, 95% CI: 1.72-43.62, p < 0.01), remained significantly associated with chronic HCV infection.Conclusions: Universal antenatal HCV screening was widely accepted (100%) and traditional risk-based screening alone would have missed 3 (10%) chronically infected women, thereby supporting universal screening of pregnant women whenever possible. Otherwise, risk-based screening should be modified to include history of prior pregnancy and healthcare employment. (C) 2015 The British Infection Association. Published by Elsevier Ltd.
