Abstract

We examined associations between prenatal oxidative stress (OS) and child autism-related outcomes. Women with an autistic child were followed through a subsequent pregnancy and that younger sibling's childhood. Associations between glutathione (GSH), glutathione disulfide (GSSG), 8-oxo-deoxyguanine (8-OHdG), and nitrotyrosine and younger sibling Social Responsiveness Scale (SRS) scores were examined using quantile regression. Increasing GSH:GSSG (suggesting decreasing OS) was associated with minor increases in SRS scores (50th percentile β: 1.78, 95% CI: 0.67, 3.06); no other associations were observed. Results from this cohort with increased risk for autism do not support a strong relationship between OS in late pregnancy and autism-related outcomes. Results may be specific to those with enriched autism risk; future work should consider other timepoints and biomarkers.

摘要

我们研究了产前氧化应激(OS)与儿童自闭症相关结局之间的关系。对自闭症儿童的母亲进行了后续妊娠和其年幼子女童年时期的随访。使用分位数回归来研究谷胱甘肽(GSH)、谷胱甘肽二硫化物(GSSG)、8-氧代-脱氧鸟嘌呤(8-OHdG)和硝基酪氨酸与年幼子女社会反应量表(SRS)评分之间的关系。GSH:GSSG 的增加(表明 OS 降低)与 SRS 评分的轻微增加相关(第 50 百分位数 β:1.78,95%CI:0.67,3.06);未观察到其他关联。来自自闭症风险增加的队列的结果并不支持妊娠晚期 OS 与自闭症相关结局之间的强关系。结果可能特定于那些具有丰富自闭症风险的人群;未来的工作应该考虑其他时间点和生物标志物。
