There are numerous physiologic and biochemical changes in menopause that can affect the function of the liver and mediate the development of liver disease. Menopause represents a state of growing estrogen deficiency, and this loss of estrogen in the setting of physiologic aging increases the likelihood of mitochondrial dysfunction, cellular senescence, declining immune responses to injury, and disarray in the balance between antioxidant formation and oxidative stress. The sum effect of these changes can contribute to increased susceptibility to development of significant liver pathology, particularly nonalcoholic fatty liver disease and hepatocellular carcinoma, as well as accelerated progression of fibrosis in liver diseases, as has been particularly demonstrated in hepatitis C virus liver disease. Recognition of the unique nature of these mediating factors should raise suspicion for liver disease in perimenopausal and menopausal women and offer an opportunity for implementation of aggressive treatment measures so as to avoid progression of liver disease to cirrhosis, liver cancer and liver failure.
更年期存在众多生理和生化变化,这些变化会影响肝脏功能并介导肝脏疾病的发生发展。更年期代表雌激素日益缺乏的状态,在生理衰老的背景下雌激素的这种丧失增加了线粒体功能障碍、细胞衰老、对损伤的免疫反应下降以及抗氧化剂形成与氧化应激之间平衡紊乱的可能性。这些变化的综合作用可导致对严重肝脏病变,特别是非酒精性脂肪性肝病和肝细胞癌的易感性增加,以及肝脏疾病纤维化进程加速,丙型肝炎病毒肝病中尤其如此。认识到这些介导因素的独特性质应提高对围绝经期和绝经后女性肝脏疾病的怀疑,并提供实施积极治疗措施的机会,以避免肝脏疾病进展为肝硬化、肝癌和肝衰竭。
