Alcohol, a widely consumed drug, exerts significant toxic effects on the human organism. This review focuses on its impact during fetal development, when it leads to a spectrum of disorders collectively termed Fetal Alcohol Spectrum Disorders (FASD). Children afflicted by FASD exhibit distinct clinical manifestations, including facial dysmorphism, delayed growth, and neurological and behavioral disorders. These behavioral issues encompass diminished intellectual capacity, memory impairment, and heightened impulsiveness. While the precise mechanisms underlying alcohol-induced fetal damage remain incompletely understood, research indicates a pivotal role for reactive oxygen species (ROS) that are released during alcohol metabolism, inciting inflammation at the cerebral level. Ethanol metabolism amplifies the generation of oxidant molecules, inducing through alterations in enzymatic and non-enzymatic systems responsible for cellular homeostasis. Alcohol consumption disrupts endogenous enzyme activity and fosters lipid peroxidation in consumers, potentially affecting the developing fetus. Addressing this concern, administration of metformin during the prenatal period, corresponding to the third trimester of human pregnancy, emerges as a potential therapeutic intervention for mitigating FASD. This proposed approach holds promise for ameliorating the adverse effects of alcohol exposure on fetal development and warrants further investigation.
酒精是一种广泛使用的药物,对人体有显著的毒性作用。本篇综述聚焦于酒精在胎儿发育期间的影响,这会导致一系列被统称为胎儿酒精谱系障碍(Fetal Alcohol Spectrum Disorders,FASD)的疾病。受 FASD 影响的儿童表现出明显的临床症状,包括面部畸形、生长迟缓以及神经和行为障碍。这些行为问题包括智力下降、记忆力损伤和冲动性增加。虽然酒精引起胎儿损伤的确切机制尚未完全阐明,但研究表明,活性氧(reactive oxygen species,ROS)在酒精代谢过程中释放,在大脑水平引发炎症,起着关键作用。乙醇代谢会增加氧化分子的生成,通过改变负责细胞内稳态的酶和非酶系统来诱导氧化应激。酒精消费会破坏内源性酶的活性,并促进消费者的脂质过氧化,这可能会影响发育中的胎儿。为了解决这个问题,在人类妊娠的第三个三个月(即产前阶段)给予二甲双胍,这可能是一种减轻 FASD 的潜在治疗干预措施。这种方法有望改善酒精暴露对胎儿发育的不良影响,值得进一步研究。
