Long-term prognosis for infants with intrahepatic cholestasis and patent extrahepatic biliary tract
Insights
Identifying infants with prolonged cholestasis early is crucial. Alpha-1-antitrypsin deficiency and scanty bile ducts indicate a poor prognosis, requiring prompt recognition for better outcomes.
Area of Science:
- Pediatrics
- Hepatology
- Neonatology
Background:
- Prolonged cholestasis in infants presents a diagnostic challenge.
- Distinguishing between various causes of neonatal cholestasis is essential for prognosis.
Purpose of the Study:
- To classify infants with prolonged cholestasis based on etiology.
- To determine prognostic factors for chronic liver disease in these infants.
Main Methods:
- Classification of 103 infants with prolonged cholestasis (onset <3 months) into three groups: alpha-1-antitrypsin deficiency, scanty interlobular bile ducts, and "neonatal hepatitis".
- Follow-up assessment for development of chronic liver disease or recovery.
Main Results:
- Seventeen infants had alpha-1-antitrypsin deficiency, 16 had scanty interlobular bile ducts, and 70 had "neonatal hepatitis".
- Twenty-two infants developed chronic liver disease; 81 recovered.
- Poor prognosis was associated with alpha-1-antitrypsin deficiency, scanty interlobular bile ducts, and familial "idiopathic" hepatitis.
- Severe neonatal cholestasis mimicking extrahepatic biliary atresia was noted in infants who developed cirrhosis.
Conclusions:
- A high-risk group of infants with prolonged cholestasis can be identified early based on etiology, family history, and cholestasis severity.
- Early recognition allows for timely intervention and management strategies.
Abstract:
One hundred and three infants with prolonged cholestasis beginning before 3 months were classified as having alpha-1-antitrypsin deficiency (17 patients), scanty interlobular bile ducts (16 patients), or "neonatal hepatitis" (70 patients). Twenty-two gradually developed chronic liver disease and the remaining 81 recovered within a few months. Prognosis was found to be poor for infants with alpha-1-antitrypsin deficiency, scanty interlobular bile ducts, and familial "idiopathic" hepatitis. Patients who developed cirrhosis often presented with severe and persistent neonatal cholestasis, mimicking extrahepatic biliary atresia and leading to laparotomy. Thus, a high-risk group of infants-defined by aetiology, family history, and degree of cholestasis-can be recognised in the first months of life.
