[Immune status of liver failure patients and related immune regulation therapy]

Liver failure refers to a series of clinical syndromes manifesting as coagulation disorders, jaundice, hepatic encephalopathy, ascites, and other decompensated abnormalities due to serious hepatic dysfunction or decompensation in terms of synthesis, detoxification, excretion, and biological transformation caused by a variety of factors. In recent years, with the development of the research on immunological pathogenesis of liver failure, the "three-hit" theory clarifies the pathogenesis of liver failure. Major therapeutic strategies for liver failure are to prevent hepatocyte necrosis, promote hepatocyte regeneration, create a good internal environment for hepatocyte regeneration, and actively prevent and treat complications. An understanding of the immune status of liver failure patients and early application of glucocorticoids at right timing may help to improve prognosis and reduce adverse reactions. Establishment of a quantitative or functional balance between different cell subsets and new thoughts on some key cytokines may provide new directions and targets for immune regulation of liver failure.
