Study Notes
Hepatic Injury
- Definition: Irreversible replacement of normal liver tissue with non-functional scar tissue, typically irreversible.
Cirrhosis
- Irreversible scarring of the liver, leading to decreased blood flow and liver function.
- Leading cause of portal hypertension.
- MC cause: Alcoholic hepatitis.
- Other causes: Viral hepatitis (Hep B & Hep C), Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD), parasitic infection, malignancy.
Portal Hypertension
- Abnormally high BP in the branches of the portal vein.
- Presentation: Enlarged abdomen, abdominal discomfort, confusion, and internal bleeding.
- MC cause: Cirrhosis.
- Complications: Esophageal varices, ascites, liver failure.
Esophageal Varices
- Engorged, tortuous, and fragile varicose vessels of the lower esophagus.
- Caused by retrograde flow into the lower esophageal vessels due to portal hypertension.
- Complications: Mass hematemesis, gastrointestinal bleeding.
Hepatic Encephalopathy
- Deterioration of brain function due to buildup of toxic substances normally removed by the liver.
- Caused by excess amounts of ammonia, an end product of normal protein breakdown.
- Symptoms: Confusion, drowsiness, coma.
Jaundice
- Yellowish appearance of the skin and whites of the eyes due to excess bilirubin in the bloodstream.
- Causes: Prehepatic (e.g., sickle cell anemia, thalassemia), intrahepatic (e.g., hepatitis, cirrhosis, hepatocellular carcinoma), posthepatic (e.g., cholelithiasis, pancreatitis, pancreatic cancer).
Epidemiology
- Twice as common in males.
- Autopsy of livers in the US reveals 5% of the population has cirrhosis.
- 25,000 deaths per year in the US.
Prognosis
- Without transplant, patient usually dies within 5-15 years due to complications of cirrhosis.
Complications
- Portal hypertension, esophageal varices, rectal varices, ascites, kidney failure, hepatic encephalopathy.
- Decreased bile production, vitamin D absorption, and vitamin K absorption.
- Tendency for bleeding, splenomegaly, anemia.
Signs and Symptoms
- May have no symptoms for several years.
- Recognizable symptoms in 2 categories: symptoms related to declining liver function and symptoms related to portal hypertension.
- MC symptoms: weakness, malaise, fatigue, weight loss, ascites, loss of appetite.
- Symptoms related to declining liver function: greasy, foul-smelling steatorrhea, fatigue, loss of appetite, weight loss, dark urine, generalized edema, malabsorption.
- Symptoms related to portal hypertension: jaundice, ascites, hepatomegaly and splenomegaly, digital clubbing, caput medusa, xanthelasma, and spider telangiectasia.
