0:00 mins

Welcome and formation of students into groups. Facilitator should assign students into groups and ask students to share the responses that were gathered individually and discuss the case discussion question.

  • Explain the epidemiology of alcoholic liver disease in the United States.

  • Is a leading cause of mortality, nearly 250,000 deaths attributed to ALD; about 4% prevalence (JAMA, May 2019);
  • ALD leading indication for liver transplants (Clin Gastroenterol Hepatol. 2018;16(8):1356-1358.).
  • About half of the deaths from cirrhosis are alcohol-related
  • List the risk factors for developing alcoholic liver disease.
  • Excessive alcohol use
  • More common in men
  • HCV
  • obesity
  • genetic
  • Describe how alcohol is normally metabolized by the liver.

Discuss with your group:

How did ethanol use lead to hepatitis in this patient?

  • by alcohol dehydrogenase (ADH)
  • cytochrome P450

0:20 mins

Facilitator: Facilitate a debrief of the responses to the learning objectives and case discussion question with the entire class for 10 minutes.

  • Describe how the liver participates in blood clotting.
  • Hemostasis is related to liver function. Coagulation factors are synthesized by liver parenchymal cells and the liver’s reticuloendothelial system serves as important role in the clearance of activation products.
  • Vitamin K dependent factors: Prothrombin (which we usually measure in the lab), factor VII, IX, X, protein C and S
  • Describe normal Starling pressures and changes that result in peripheral edema and ascites in a patient with alcoholic liver disease.
Normal:

  • Pc = capillary pressure
  • Pi = interstitial fluid pressure
  • πc = plasma colloid oncotic pressure
  • πi = interstitial fluid colloid osmotic pressure

Edema:

  • In this case, the peripheral edema is caused by decreased plasma proteins and increased interstitial fluid pressure.
  • Ascites in this case is from increased portal pressures and the “weeping” of fluids off the surface of the liver.
  • List the normal progression of alcoholic liver disease.
  • Steatosis
  • Steatohepatitis
  • Cirrhosis
  • Hepatocellular carcinoma

0:50 mins

Facilitate a debrief of the responses to the learning objectives and case discussion question with the entire class for 10 minutes.

0:60 mins

At 60 minutes: BREAK for 10 minutes


1:10 mins

Facilitator should assign students into groups and ask students to share the responses that were gathered individually and discuss the case discussion question.

  • List the signs and symptoms of alcoholic liver disease.

Discuss with your group:

What causes this patient’s peculiar breath (fetor hepaticus)?

  • Sometimes asymptomatic
  • with cirrhosis – jaundice, weakness, edema, swollen abdomen, GI bleed
  • evidence of hepatomegaly on physical exam
  • ascites
  • evidence of encephalopathy
  • skeletal muscle wasting/weakness
  • white discoloration of fingernails (leukonychia)
  • gynecomastia
  • testicular atrophy
  • palmar erythema
  • halitosis
  • Contrast liver function laboratory results from a patient with alcoholic liver disease to normal lab findings and to patients with other forms of liver disease.

Discuss with your group:

Why is bilirubin elevated in this case?

  • The aspartate aminotransferase (AST) to alanine aminotransferase (ALT) ratio is >2 in ALD patients.
  • ALT is often higher than serum AST in patients with other forms of liver disease.
  • elevated transaminases in ALD patients
  • elevated gamma-glutamyl transpeptidase (GGT) in patients with ALD (not specific to ALD)
  • Blood findings in patients with ALD:
  • Elevated bilirubin
  • Thrombocytopenia
  • Anemia
  • Elevated MCV
  • Decreased lymphocyte count
  • Increased ESR
  • Increased INR
  • Radiographic image findings:
  • Signs of hepatic steatosis
  • Determine the correct evaluation and testing to make a diagnosis for the patient in this case.
  • Determine alcohol consumption
  • Physical exam – angiomata, ascites, gynecomastia, URQ tenderness
  • Lab tests – discussed above

1:30 mins

Facilitate a debrief of the responses to the learning objectives and case discussion question with the entire class for 10 minutes.

  • Determine differential diagnoses for the patient in this case.
  • Hepatitis C, Hepatitis B
  • NAFLD
  • Wilson
  • Acute liver injury
  • Develop a management scheme for the patient.

Discuss with your group:

What interventions have been proven effective to address alcoholism?

What social support is currently available in our community?

  • Counsel on alcohol intake
  • What meds to prescribe?
  • Counsel on diet and vitamin use
  • Counsel on acetaminophen
  • Describe when patients need a liver biopsy.
  • Patient with abnormal serum aminotransferase that persisted for more than six months without a clear explanation.
  • Patient with normal liver enzymes but BMI > 30

1:50 mins

Facilitate a debrief of the responses to the learning objectives and case discussion question with the entire class for 10 minutes.
