Sclerosing cholangitis with neonatal onset
Insights
This study details eight children with a rare form of pediatric sclerosing cholangitis, presenting with early cholestasis, cirrhosis, and portal hypertension. Findings highlight characteristic bile duct abnormalities visible through imaging.
Area of Science:
- Pediatric Gastroenterology
- Hepatology
- Radiology
Background:
- Sclerosing cholangitis involves bile duct narrowing, typically diagnosed via imaging in adults.
- Pediatric cases often present with unique clinical trajectories.
Purpose of the Study:
- To describe the clinical, histological, and radiological features of sclerosing cholangitis in eight children.
- To characterize the progression of liver disease in affected pediatric patients.
Main Methods:
- Clinical follow-up of eight children diagnosed with cholestasis from the first week of life.
- Histological examination of liver biopsies.
- Radiological assessment using percutaneous cholecystography under ultrasound guidance.
Main Results:
- Children presented with early-onset cholestasis, progressing to cirrhosis and portal hypertension.
- Histology revealed absence of interlobular bile ducts and later biliary cirrhosis.
- Radiology showed intrahepatic bile duct abnormalities including rarefaction, stenosis, and dilation, with extrahepatic involvement in most cases.
Conclusions:
- This cohort demonstrates a distinct presentation of sclerosing cholangitis in children, differing from adult forms.
- Early cholestasis and progressive liver damage are key features, necessitating specific diagnostic and management approaches.
Abstract:
Sclerosing cholangitis is characterized by irregular narrowing of extrahepatic or intrahepatic bile ducts, and in adults is defined mainly by radiologic findings. We describe eight children with cholestasis from the first week of life, followed by early cirrhosis and portal hypertension. Histologic examination of the liver showed absence of interlobular bile ducts in the early cholestatic phase in two patients and biliary cirrhosis later in all patients. Radiologic examination by percutaneous cholecystography under ultrasound guidance, carried out at age 8 months to 9 years, disclosed abnormal intrahepatic bile ducts with rarefaction of segmental branches, stenosis, and focal dilation. The extrahepatic ducts were involved in six patients. No intestinal disease has been found in these patients.
