Neonatal hepatitis

Last edited: 4/15/2026

Overview

Neonatal hepatitis syndrome encompasses various liver diseases causing conjugated hyperbilirubinaemia in infants, typically presenting with jaundice lasting more than 2 weeks 12. It encompasses multiple etiologies including infectious, structural, metabolic, genetic, and idiopathic causes 2.

Diagnosis

  • Key Criteria: Jaundice persisting beyond 2 weeks, conjugated hyperbilirubinaemia, pale stools, dark or yellow urine 12.
  • Recommended Tests: Measure serum conjugated bilirubin, evaluate liver function tests, imaging (e.g., ultrasound), and consider liver biopsy if necessary 12.
  • Urgent Investigation: Confirm or exclude biliary atresia within one week 1.
  • Early Diagnosis: Critical for optimal outcomes, especially for conditions like biliary atresia 2.

    • Management

  • First-Line Treatments:
    • - Supportive Care: Focus on nutritional needs and hydration 2. - Vitamin Supplementation: Vigorous supplementation of fat-soluble vitamins, including parenteral vitamin K if coagulation is abnormal 1.
  • Definitive Treatments:
    • - Surgical Interventions: Early surgical correction for biliary atresia before 8 weeks of age 2. - Liver Transplantation: Consider for severe cases unresponsive to other treatments 2.

    Special Populations

  • No Specific Guidance: Abstracts do not provide detailed recommendations specific to pregnancy, pediatrics beyond neonatal period, elderly, or comorbidities 12.

    • Key Recommendations

  • Investigate neonatal jaundice lasting more than 2 weeks with serum conjugated bilirubin measurement; urgent evaluation for biliary atresia is essential (Evidence: Strong 1).
  • Confirm or exclude biliary atresia within one week to facilitate timely surgical intervention if needed (Evidence: Strong 1).
  • Initiate vigorous fat-soluble vitamin supplementation, including parenteral vitamin K if coagulation abnormalities are present (Evidence: Moderate 1).
  • Perform early definitive treatments for identifiable causes of neonatal hepatitis syndrome and consider liver transplantation for severe cases (Evidence: Moderate 2).
