Overview
Cholestatic jaundice in infancy is a pathologic condition indicating hepatobiliary dysfunction, affecting approximately 1 in every 2500 term infants 1. It requires early detection and timely specialist referral for optimal outcomes.Diagnosis
Infants jaundiced after 2 weeks of age should be evaluated for cholestasis 1.
Key tests include measurement of total and direct serum bilirubin 1.
Additional evaluations may include liver function tests, imaging studies (e.g., abdominal ultrasound), and genetic testing as indicated 1.Management
Biliary Atresia: Kasai portoenterostomy is the primary surgical intervention 1.
Monogenic Disorders: Management depends on specific genetic diagnosis; may include enzyme replacement therapy or specific pharmacological interventions as indicated 1.
Supportive Care: Nutritional support, including possibly parenteral nutrition with close monitoring for complications 1.
Regular Monitoring: Frequent follow-up to assess liver function and growth parameters 1.Special Populations
Pediatrics: Early intervention is crucial for infants due to the time-sensitive nature of many causes 1.Key Recommendations
Evaluate infants with jaundice persisting beyond 2 weeks of age for cholestasis using serum bilirubin measurements 1 (Evidence: Strong).
Prompt referral to pediatric gastroenterology/hepatology specialists for comprehensive evaluation and management 1 (Evidence: Strong).
Consider genetic testing in cases of suspected monogenic disorders contributing to cholestatic jaundice 1 (Evidence: Moderate).References
