Mortality in cirrhosis is mostly associated with the development of clinical decompensation, characterized by ascites, hepatic encephalopathy, variceal bleeding, or jaundice. Therefore, it is important to prevent and manage such complications. Traditionally, the pathophysiology of decompensated cirrhosis was explained by the peripheral arterial vasodilation hypothesis, but it is currently understood that decompensation might also be driven by a systemic inflammatory state (the systemic inflammation hypothesis). Considering its oncotic and nononcotic properties, albumin has been thoroughly evaluated in the prevention and management of several of these decompensating events. There are formal evidence-based recommendations from international medical societies proposing that albumin be administered in individuals with cirrhosis undergoing large-volume paracentesis, patients with spontaneous bacterial peritonitis, those with acute kidney injury (even before the etiological diagnosis), and those with hepatorenal syndrome. Moreover, there are a few randomized controlled trials and meta-analyses suggesting a possible role for albumin infusion in patients with cirrhosis and ascites (long-term albumin administration), individuals with hepatic encephalopathy, and those with acute-on-chronic liver failure undergoing modest-volume paracentesis. Further studies are necessary to elucidate whether albumin administration also benefits patients with cirrhosis and other complications, such as individuals with extraperitoneal infections, those hospitalized with decompensated cirrhosis and hypoalbuminemia, and patients with hyponatremia.
肝硬化患者的死亡率主要与临床失代偿的发生相关,其特征为腹水、肝性脑病、静脉曲张出血或黄疸。因此,预防和处理这些并发症非常重要。传统上,失代偿性肝硬化的病理生理学用外周动脉血管舒张假说来解释,但目前认为,失代偿也可能由全身性炎症状态驱动(全身性炎症假说)。鉴于白蛋白具有胶体和非胶体特性,其在预防和处理多种失代偿事件中的作用已得到充分评估。国际医学协会有正式的循证推荐,建议在进行大量腹腔穿刺术的肝硬化患者、自发性细菌性腹膜炎患者、急性肾损伤患者(甚至在病因诊断之前)以及肝肾综合征患者中输注白蛋白。此外,有一些随机对照试验和荟萃分析表明,白蛋白输注对肝硬化伴腹水(长期白蛋白治疗)、肝性脑病患者和接受少量腹腔穿刺术的慢性肝衰竭急性发作患者可能具有一定作用。需要进一步研究以阐明白蛋白给药是否也有益于肝硬化和其他并发症患者,例如合并腹膜外感染、因失代偿性肝硬化和低白蛋白血症住院以及伴低钠血症的患者。
