Research advances in alcoholic liver disease with sarcopenia
-
摘要: 酒精性肝病是影响我国人民健康的主要肝脏疾病之一, 约有60%的酒精性肝病患者合并肌肉减少症。就酒精性肝病发生肌肉减少症的机制而言,除了肝病患者存在食欲下降、营养物质摄入不足、消化吸收障碍、体力活动减少、血氨升高等因素外,酒精及其代谢产物还可作用于多个信号通路影响骨骼肌蛋白合成,促进骨骼肌细胞自噬。酒精性肝病患者合并肌肉减少症发生肝性脑病、肝癌等不良预后风险增加。针对酒精性肝病患者肌肉减少症的干预措施有待深入研究。Abstract: Alcoholic liver disease (ALD) is one of the most common liver diseases affecting the health of the Chinese people, and about 60% of ALD patients suffer from sarcopenia. Anorexia, inadequate intake of nutrients, disorder of digestion and absorption, reduction in physical activity, and increase in blood ammonia are common causes of sarcopenia in patients with ALD; besides, alcohol and its metabolites may affect the synthesis of skeletal muscle protein and promote the autophagy of skeletal muscle cells through multiple signaling pathways. Patients with ALD and sarcopenia tend to have increased risks of poor prognosis, such as hepatic encephalopathy and liver cancer. Further studies are needed to investigate the interventions for patients with ALD and sarcopenia.
