Study Notes
Stigmata of Liver Disease
Hands
- Palmar Erythema: Reddening of the palms, indicative of increased estrogen levels and liver dysfunction.
- Clubbing: Enlargement and rounding of the fingertips, potentially linked to chronic hypoxia, often seen in liver disease.
- Dupuytren's Contracture: Thickening and shortening of the palmar fascia leading to finger flexion, associated with liver cirrhosis.
- Leukonychia: White nails, which can signal liver disease or hypoalbuminemia.
- Flapping Tremor: Involuntary tremors of the hands (asterixis), reflecting metabolic disturbances in hepatic failure.
Head/Upper Body
- Jaundice: Yellowing of the skin and sclera due to increased bilirubin levels, a sign of liver dysfunction.
- Spider Angiomata: Small, spider-like blood vessels visible under the skin, commonly associated with liver cirrhosis and estrogen excess.
- Gynecomastia and Scant Body Hair: Breast tissue enlargement in males and reduced hair growth due to hormonal imbalances related to liver failure.
- Scratch Marks: Often a result of itching due to bile salt accumulation, commonly seen in liver disease.
Abdomen
- Ascites: Accumulation of fluid in the abdominal cavity, often due to portal hypertension and liver cirrhosis.
- Hepatosplenomegaly: Enlargement of the liver and spleen, frequently a result of liver disease.
- Caput Medusa: Distended veins around the umbilicus, indicative of portal hypertension.
- Hemorrhoids on PR: Swollen veins in the rectal area due to increased pressure from portal hypertension.
- Small Testes: Can indicate hormonal changes or dysfunction associated with liver disease, particularly in males.
Autoimmune Hepatitis
- Characterized by positive ANA and anti-smooth muscle antibodies.
- Elevated bilirubin and ALT levels with normal alkaline phosphatase, distinguishing it from primary biliary cirrhosis.
- Common symptoms include tiredness, anorexia, right upper quadrant pain, and cushingoid facies without exogenous steroid use.
- Presents with signs of liver disease.
- Pathological findings include piecemeal necrosis and lymphocyte infiltration of liver tissue.
- Treatment involves immunosuppression and potentially liver transplant.
- Complications mirror those associated with chronic liver disease.
Primary Biliary Cirrhosis
- Marked by elevated alkaline phosphatase and positive antimitochondrial antibodies.
- Results from chronic granulomatous inflammation damaging intralobular bile ducts.
- Frequently associated with other autoimmune conditions such as thyroid disorders, rheumatoid arthritis, Sjögren's syndrome, and systemic sclerosis.
- Biopsy reveals granulomas rather than piecemeal necrosis.
- Causes bile excretion issues, leading to malabsorption of fat-soluble vitamins and symptoms of portal hypertension.
- Common presentation includes lethargy, itching, increased alkaline phosphatase, often in middle-aged women.
- May lead to hyperlipidemia.
- Important to consider in patients with existing autoimmune diseases who present with liver dysfunction.
Non-Alcoholic Steatohepatitis (NASH)
- A prevalent cause of elevated liver function tests.
- Commonly associated with metabolic syndrome, characterized by obesity, hyperlipidemia, and diabetes.
- Roughly 20-30% of patients may progress to cirrhosis.
- Management through weight loss and control of lipid levels and diabetes may slow disease progression.
Hepatocellular Carcinoma
- Key risk factors include Hepatitis B and C infections, cirrhosis of various etiologies, and exposure to Aspergillus flavus toxin.
- Annual screening for alpha-fetoprotein is recommended for patients with cirrhosis; ultrasound studies are warranted if levels are elevated.
- Less than 15% of cases are resectable at the time of diagnosis.
