Differential Diagnosis for Elevated AST and ALT in a 6-year-old

Single Most Likely Diagnosis

  • Viral Hepatitis: This is often the most common cause of elevated liver enzymes in children, with hepatitis A being more common in this age group due to exposure to contaminated food or water, or through close contact with an infected individual.

Other Likely Diagnoses

  • Non-Alcoholic Fatty Liver Disease (NAFLD): Although more commonly associated with obesity and metabolic syndrome, NAFLD can occur in children and is a significant cause of elevated liver enzymes.
  • Medication-induced Hepatotoxicity: Various medications, including certain antibiotics and anticonvulsants, can cause liver enzyme elevations.
  • Autoimmune Hepatitis: An autoimmune condition where the body's immune system attacks liver cells, leading to inflammation and elevated liver enzymes.

Do Not Miss Diagnoses

  • Wilson's Disease: A genetic disorder leading to copper accumulation in the liver, which can cause liver damage and elevated liver enzymes. Early diagnosis is crucial for treatment and prevention of long-term liver damage.
  • Alpha-1 Antitrypsin Deficiency: A genetic disorder that can lead to liver disease and elevated liver enzymes. It's essential to diagnose this condition early to manage liver disease and prevent complications.
  • Acute Hepatic Ischemia: Reduced blood flow to the liver can cause significant elevations in liver enzymes and is a medical emergency.

Rare Diagnoses

  • Glycogen Storage Diseases: A group of genetic disorders affecting glycogen metabolism, some of which can lead to elevated liver enzymes.
  • Mitochondrial Disorders: Conditions affecting the mitochondria, such as mitochondrial hepatopathies, can cause elevated liver enzymes among other systemic symptoms.
  • Budd-Chiari Syndrome: A rare condition caused by obstruction of the hepatic veins, leading to liver congestion, damage, and elevated liver enzymes.
