Overview
Cholestasis in newborns refers to impaired bile flow, often presenting with jaundice, pruritus, and malabsorption, potentially leading to severe complications including coagulopathy and nutritional deficiencies 12.Diagnosis
Clinical Features: Jaundice, pruritus, steatorrhoea, bleeding tendencies, malnutrition, and developmental delays 2.
Laboratory Tests: Elevated serum bilirubin, profound hypoprothrombinemia, elevated alkaline phosphatase, and secondary hyperparathyroidism 2.
Imaging: Ultrasound may show hepatomegaly or biliary ductal abnormalities, though specific imaging findings can vary 2.
Genetic Testing: Considered for suspected familial forms to identify specific mutations 2.Management
Supplementation: Fat-soluble vitamin supplementation (e.g., vitamin K and A) to address deficiencies and prevent complications 1.
Nutritional Support: Ensure adequate nutrition, possibly requiring parenteral support in severe cases 1.
Monitoring: Regular monitoring of liver function tests, coagulation profiles, and nutritional status 12.
Supportive Care: Management of symptoms like pruritus and infections, with supportive care tailored to individual needs 2.Special Populations
Pregnancy: Pregnant women with cholestasis are at risk for fat-soluble vitamin deficiencies, necessitating prompt supplementation to prevent maternal and fetal complications 1.
Pediatrics: Early recognition and management are crucial in children to prevent irreversible damage such as bleeding, infections, and developmental delays 2.Key Recommendations
Identify and Treat Vitamin Deficiencies: Prompt supplementation with fat-soluble vitamins, particularly vitamin K and A, to prevent coagulopathy and other deficiencies (Evidence: Strong 1).
Regular Monitoring: Implement routine monitoring of liver function, coagulation parameters, and nutritional status in affected newborns (Evidence: Moderate 12).
Genetic Counseling: Offer genetic counseling for families with suspected familial forms of cholestasis due to potential autosomal recessive inheritance (Evidence: Expert opinion 2).References
