摘要

Prenatal exposure to nonylphenol (NP) and/or bisphenol A (BPA) has been reported to be associated with adverse birth outcomes; however, the underlying mechanisms remain unclear. The primary mechanism is endocrine disruption of the binding affinity for the estrogen receptor, but oxidative stress and inflammation might also play a contributory role. We aimed to investigate urinary NP and BPA levels in relation to biomarkers of oxidativeitrative stress and inflammation and to explore whether changes in oxidativeitrative stress are a function of prenatal exposure to NP/BPA and inflammation in 241 mother-fetus pairs. Third-trimester urinary biomarkers of oxidativeitrative stress were simultaneously measured, including products of oxidatively and nitratively damaged DNA (8-hydroxy-2'-deoxyguanosine (8-OHdG) and 8-nitro- guanine (8-NO_2Gua)) as well as products of lipid peroxidation (8-iso- prostaglandin F_(2a) (8-isoPF_(2a)) and 4-hydroxy-2-nonenal-mercapturic acid (HNE-MA)). The antioxidant glutathione peroxidase (GPx) and inflammation biomarkers, including C-reactive protein (CRP) and a panel of cytokines (interleukin-6 (IL-6) and tumor necrosis factor-a (TNF-a)), were analyzed in maternal and umbilical cord plasma samples. In adjusted models, we observed significant positive associations between NP exposure and 8-OHdG and 8-NO_2Gua levels, between BPA and 8-isoPF_(2a) levels, and between maternal CRP levels and HNE-MA levels. Additionally, BPA and TNF-a levels in cord blood were inversely associated with maternal and GPx levels in cord blood as well as maternal TNF-a levels were inversely associated with maternal GPx levels. These results support a role for exposure to NP and BPA and possibly inflammation in increasing oxidativeitrative stress and decreasing antioxidant activity during pregnancy.
