Overview
Idiopathic hepatitis in infancy refers to liver inflammation without a discernible cause, primarily affecting neonates and young infants, often presenting with elevated liver enzymes and potential liver failure 1.Diagnosis
Elevated liver enzymes (ALT, AST) 1
Imaging may reveal nonspecific findings; specific diagnostic criteria often rely on exclusion of other causes 1
Histopathological examination may show features of hepatocellular injury without clear etiology 1Management
Supportive care including hydration, nutritional support, and monitoring for complications 1
Liver transplantation may be considered in cases of severe liver failure 1
No specific pharmacological treatments are widely recommended based on current evidence 1Special Populations
Pregnancy/Twin-Twin Transfusion Syndrome: Pulmonary arterial and intracranial calcifications can occur in affected infants, though not directly related to idiopathic hepatitis 1Key Recommendations
Exclude other causes of liver disease through comprehensive clinical evaluation and laboratory testing (Evidence: Expert opinion) 1
Initiate supportive care measures tailored to the severity of liver dysfunction (Evidence: Expert opinion) 1
Consider liver transplantation for infants with irreversible liver failure (Evidence: Expert opinion) 1References
