Acute-on-Chronic Liver Failure on Older Patients -an Overview

Acute-onset liver failure (ACLF), a severe manifestation of rapidly decompensating liver fibrosis, was not well reported until 2013. This disease is characterized by a rapid onset of death and failure of the hepatic system. Liver disease is a major cause of death in patients each year. More than 30 million Americans have liver disease, and more than 29 million Americans have chronic liver problems. Age-related changes in the liver include decreased cytochrome P450 activity that can affect drug metabolism and increase susceptibility to drug-induced liver injury, significant reductions in liver volume and blood flow, and decreased immune responses against infection or cancer cells. However, older adults may be more susceptible to autoimmunity due to decreased regulatory T cells and impaired maturation of dendritic cells. Because of changes in the liver, patients with liver disorders may experience a variety of clinical manifestations and outcomes. The pathophysiology of viral hepatitis, autoimmune liver disorders, and the onset of hepatocellular carcinoma may be influenced by these changes in immune function. Furthermore, treatment of liver disease is less appropriate for elderly patients due to the significantly reduced reserve functions of many organs. Age-related changes in the liver and other organs may have an impact on the treatment course and clinical features of liver disease in the elderly. An overwhelming systemic inflammatory response caused by clinically obvious etiological factors (such as confirmed microbiological infection associated with sepsis or severe alcohol-related hepatitis) or clinically unclear causes acute-chronic liver failure. Following the classification of acute-chronic liver failure (ACLF), several important studies have shown that patients with this condition should be stabilized as soon as possible in order to potentially benefit from liver transplantation. Receive comprehensive general care, which includes appropriate treatment in the intensive care unit and support of organ systems in the identified etiological factors.
