Pathology – Alcoholic liver illness
Definition: Liver disease brought on by heavy alcohol use. There are three recognized disease patterns: cirrhosis, alcoholic steatohepatitis (ASH), and steatosis.
The study of epidemiology • Very prevalent.
The pathogenesis • High amounts of NADH produced by the liver's breakdown of alcohol promote the synthesis of fatty acids and triglycerides, which results in steatosis. • In certain people, oxidative stress brought on by alcohol metabolism results in hepatocyte damage and necroinflammatory response (ASH). • Liver fibrosis, which can develop into cirrhosis, is brought on by persistent necroinflammatory activity. Display Although mild ASH and steatosis are typically asymptomatic, they are frequently the source of modestly abnormal liver function tests. • After binge drinking, severe alcoholic hepatitis results in fever, malaise, and a substantial increase in liver function tests. If there is a significant decline in liver function, jaundice may develop. • Alcoholic cirrhosis manifests as cirrhosis complications, such as ruptured oesophageal varices or ascites. The macroscopy Steatosis results in a mushy, greasy, swollen liver. Because of cirrhosis, the liver develops diffuse nodules, and ASH can result in a firm texture.
The study of histopathology • Hepatocytes with steatosis exhibit enormous fat droplets that push the nucleus to one side (macrovesicular steatosis). • Inflammatory infiltrate rich in neutrophils and Mallory's hyaline, which are clusters of dense pink material, may be present in ASH's enlarged hepatocytes. ASH usually causes pericellular fibrosis, which eventually develops into fibrous bridges. • Nodules of regenerating hepatocytes encircled by fibrous bands diffusely replace the liver in cirrhosis. Hepatitis and background steatosis might not be present.
Prognosis: If alcohol use stops, simple steatosis can be completely reversed. • Alcoholic hepatitis can either go away when alcohol use stops or it can develop into cirrhosis and fibrosis.
• The 5-year survival rate for alcoholic cirrhosis is only 50%, which indicates a bad prognosis.
