Disorders of the Liver (PEARLS)

The NCCPA™ Gastroenterology and Nutrition Content Blueprint covers 3 topics under the category disorders of the liver

Acute and chronic hepatitis Symptoms: Tea colored urine, vague abdominal discomfort, nausea, pruritus, pale stool

Hepatitis A

  • Acute
  • Transmission: Fecal-oral

Hepatitis B

  • Acute and Chronic
  • Transmission: Sexual or sanguineous
  • Serology:
  • HBeAg – highly infectious
  • HBsAg – ongoing infection
  • Anti-HBc – had/have infection
    • IgM – acute
    • IgG – not acute
  • Anti-HBs – immune
  • Risk of hepatocellular carcinoma

Hepatitis C

  • Chronic
  • Asymptomatic
  • Transmission: IV drug use is most common. Also sexual or sanguineous
  • Risk of cirrhosis and hepatocellular carcinoma

Hepatitis D

  • Only occurs when coinfected with Hepatitis B*
  • Risk of hepatocellular carcinoma

Hepatitis E

  • Pregnant woman, 3rd world countries
  • Hepatitis E + mother = high infant mortality

Treatment: Supportive. Vaccinate against other viral hepatitis. HIV treatment PRN.

  • Hepatitis C- Pegylated interferon and ribavirin

Alcoholic Hepatitis

  • Liver enzymes: AST:ALT ratio > 2:1

Toxic Hepatitis

  • Acetaminophen toxicity: Treatment with N-Acetylcysteine within 8-10 hrs

Fatty Liver Disease:

  • Risk factors: Obesity, hyperlipidemia, insulin resistance
  • Liver enzymes: ALT > AST
  • Liver biopsy: Large fat droplets (macrovesicular fatty infiltrates)

Hepatitis B Serology

Hepatitis Serology      
Anti-HBc IgM Anti-HBc IgG HBsAG Anti-HBs Interpretation
+ - + - Acute HBV
- - + - Early acute HBV
- + - + Resolved acute HBV
- - - + HBV vaccine/Immunity
- - - - No infection or immunity
- + + - Chronic HBV

Hepatitis C Serology

HCV RNA Anti-HCV
Acute Hepatitis C + ±
Resolved Hepatitis C - ±
Chronic Hepatitis C + +

Hepatitis A Serology

IgM HAV Ab IgG HAV Ab
Acute Hepatitis A +
Past exposure - +

 

Cirrhosis (ReelDx) Chronic hepatitis most common cause of cirrhosis

Labs: typically AST > ALT, ↑ risk for hepatocellular carcinoma: monitor AFP, Hepatic vein thrombosis: Budd Chiari: triad of abdominal pain, ascites and hepatomegaly

Presentation:

  • Ascites, pulmonary edema/effusion, esophageal varices, Terry’s nails (white nail beds)
  • Skin changes: spider angiomata, palmar erythema, jaundice, scleral icterus, ecchymoses, caput medusae, hyperpigmentation

Hepatic encephalopathy:

  • Asterixis (flapping tremor), dysarthria, delirium, coma

Treatment: Avoid alcohol, restrict salt, transplant

Liver neoplasms (ReelDx) Abdominal pain, weight loss, right upper quadrant mass

Etiology: Cirrhosis, Hepatitis B, Hepatitis C, Hepatitis D, Aflatoxin from aspergillus

  • Tumor Marker: ↑ alpha-fetoprotein and abnormal liver imaging
  • Treatment: Resect, Transplant
  • Poor prognosis
