BACKGROUND AND AIM: We aim to assess the association between maternal hepatitis C virus (HCV) viral load and human immunodeficiency virus (HIV) coinfection and the risk for mother-to-child transmission (MTCT) among pregnant women infected with HCV.
METHODS: A literature search of the Medline, Embase, Central, Science Citation Index Expanded (SCIE), Conference Proceedings Citation Index-Science (CPCIS), Scopus, Literature Latino-Americana e do Caribe em Ciências da Saúde (LILACS), and WHO Global Index Medicus databases, from inception to June 21, 2022, was performed. Studies that reported the incidence HCV-MTCT were included. Pooled effect estimates were calculated using the random-effects model, and Holm-Bonferroni correction was performed for multiple pooled associations.
RESULTS: The present meta-analysis included 26 studies involving 4934 newborns with maternal HCV infection. Pregnant women with HCV viremia exhibited increased risk for MTCT (odds ratio [OR] 8.25 [95% confidence interval (CI) 4.65-14.63]) compared with those negative for HCV-RNA. Multiple subgroup analysis revealed that the HCV viremia/HIV-positive group demonstrated the highest risk for HCV MTCT, followed by the HCV viremia mono-infected group, while HCV-RNA-negative women demonstrated the lowest risk for HCV MTCT. Among females with HCV viremia, elevated risk for MTCT was found among subjects with a viral load ≥ 6 log10 copies/mL compared with those with viral load < 6 log10 copies/mL (OR 4.58 [95% CI: 2.52-8.34]).
CONCLUSION: The incidence of HCV MTCT was increased among pregnant women with detectable HCV viremia and was even higher in those with a viral load ≥ 6 log10 copies/mL. HIV coinfection further increased the risk for HCV MTCT.
