摘要:

人血清白蛋白(human serum albumin,HSA)是人体血浆中一种含量丰富的蛋白质,参与行使机体多种生理功能。该文介绍了HSA的生物合成与代谢、结构与功能,并总结了HSA在失代偿期肝硬化中的临床应用进展以及不良反应。HSA作为一种结构复杂的多功能分子,不仅可以提升血浆胶体渗透压,近年来其结合转运、抗氧化、调节免疫、调节循环功能、维持内皮细胞稳定和毛细血管通透性等非胶体功能也受到广泛重视。HSA结构易受到疾病环境的影响,翻译后修饰可发生多种类型的变化,如N末端或C末端截断、糖基化、第34个半胱氨酸残基(Cys-34)氧化等,其中Cys-34氧化程度与肝硬化病程进展及生存结局相关。除了可以预防腹腔穿刺引流大量腹水后的循环功能紊乱,HSA在肝肾综合征(hepatorenal syndrome,HRS)、自发性腹膜炎(spontaneous peritonitis,SBP)等多种肝硬化并发症的管理中表现出良好的治疗效果。对于非SBP感染、腹水的长期管理、肝性脑病、慢加急性肝衰竭(acute-on-chronic liver failure,ACLF)等其他肝硬化并发症,HSA的治疗效益仍存在争议,需要进一步的临床试验研究。

Abstract:

Human serum albumin (HSA) is one of the most abundant proteins in the plasma which participate in plenty of physiological functions. This article reviews recent advances in HSA-related researches with respect to its synthesis, metabolism, structure, function, and clinical application in decompensated cirrhosis and its adverse events. As a multidomain polyfunctional molecule, HSA has not only shown its effect on colloid osmotic pressure elevation, but also its non-colloid functions including ligand binding capacity, antioxidant ability, immunoregulatory effect, and maintaining the stability of endothelium and permeability of capillary. However, the structure of HSA is easily affected by pathology surroundings including various posttranslational modifications of HSA, such as truncated N-terminal or C-terminal, glycosylation, and oxidation of Cys-34. Among these, the oxidation modification of Cys-34 in HSA is closely related to cirrhosis progression and has a strong prognostic ability of clinical outcomes. Besides prevention of post paracentesis circulatory dysfunction, HSA administration also shows excellent treatment potentials in the cirrhotic complications, including hepatorenal syndrome (HRS) and spontaneous peritonitis (SBP). Furthermore, more clinical trials are needed to discuss the potential benefits of HSA in non-SBP infection, long-term administration of ascites, hepatic encephalopathy, acute-on-chronic liver failure (ACLF) and other cirrhotic complications.

Key words: human serum albumin (HSA), decompensated cirrhosis, ascites, acute-on-chronic liver failure (ACLF)
