Pathophysiology and Diagnosis of Chronic Liver Disease

Abstract

Chronic liver disease (CLD) is caused by an inflammatory damage to the liver that lasts six months or more. The development of new blood vessels, regardless of the underlying aetiology, is a fundamental process in the pathogenesis of chronic liver diseases (CLDs). Given the fact that CLDs often advance from hepatocyte injury to inflammation, fibrosis, cirrhosis, and, in rare circumstances, hepatocellular cancer, CLDs cannot be regarded a single illness (HCC). Neovascularisation and the creation of an aberrant angioarchitecture are linked in the pathological course of CLDs. Asymptomatic individuals with modestly increased liver enzymes such as Alanine Transaminase (ALT) and Aspartate Transaminase (ALT) are frequently found in basic care. Biochemical indicators include serum bilirubin, alanine amino transferase, aspartate amino transferase, aminotransferase ratio, alkaline phosphatase, gamma glutamyltransferase, 5' nucleotidase, ceruloplasmin, and alpha-fetoprotein. In conclusion, further epidemiological and pathophysiology research is needed. A better knowledge of the molecular pathways behind geriatric chronic liver disease will aid in determining the best diagnostic and treatment strategy for each older patient.
