<jats:title>Abstract</jats:title><jats:sec><jats:title>Aim</jats:title><jats:p>To study reduced glutathione (GSH) as a marker of oxidative stress in hepatitis E virus (HEV) infection during pregnancy, and to clarify its association with pregnancy outcome.</jats:p></jats:sec><jats:sec><jats:title>Methods</jats:title><jats:p>A total of 30 pregnant and 30 non‐pregnant women with HEV infection were enrolled in the present study, along with 30 age‐ and gestation‐matched healthy pregnant controls. Serum GSH was measured using commercially available enzyme‐linked immunoassay kit.</jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p>Significantly lower GSH was observed in HEV‐infected pregnant women than in healthy pregnant controls (10.44 ng/mL vs 19.77 ng/mL; <jats:italic>P</jats:italic> < 0.01). No significant association was observed between GSH and pregnant women and non‐pregnant women with HEV infection (<jats:italic>P</jats:italic> = 0.54). Serum GSH ≤10.88 ng/mL was more likely to be associated with HEV infection during pregnancy, with sensitivity and specificity of 73.3%. Lower GSH was observed in pregnant women with HEV infection having preterm delivery and low birthweight newborns compared with healthy pregnant women (<jats:italic>P</jats:italic> < 0.01 and <jats:italic>P</jats:italic> < 0.05, respectively). Serum GSH was lower in pregnant women with HEV infection who had stillbirth compared with those having live births (7.21 ng/mL vs 6.12 ng/mL, <jats:italic>P</jats:italic> = 0.60).</jats:p></jats:sec><jats:sec><jats:title>Conclusion</jats:title><jats:p>Oxidative stress is present in HEV infection during pregnancy, as shown by low GSH, and is associated with adverse pregnancy outcomes. Serum GSH ≤10.88 ng/mL during pregnancy can be used for risk stratification for HEV infection.</jats:p></jats:sec>
