Cholelithiasis and Wilson disease
Insights
Children with Wilson disease (WD) frequently develop gallstones. These gallstones have higher cholesterol content, suggesting WD patients need regular gallstone screening to prevent complications.
Area of Science:
- Hepatology
- Pediatric Gastroenterology
- Genetics
Background:
- Wilson disease (WD) is a rare genetic disorder characterized by copper accumulation.
- Gallstones (cholelithiasis) can occur in children and may be asymptomatic for years.
- Clinical presentation of WD can be varied, sometimes mimicking other conditions.
Purpose of the Study:
- To investigate the prevalence and characteristics of gallstones in children with Wilson disease.
- To compare the composition of gallstones in WD patients with those in age-matched controls.
- To assess the clinical significance of gallstones in the pediatric Wilson disease population.
Main Methods:
- Case study of three children diagnosed with Wilson disease.
- Clinical evaluation for cholecystitis symptoms and radiological assessment for gallstones.
- Surgical confirmation of gallstones via laparotomy.
- Biochemical analysis of gallstone composition, focusing on cholesterol content.
Main Results:
- All three studied children with Wilson disease presented with symptoms and radiological evidence of gallstones.
- Gallstones from Wilson disease patients exhibited significantly higher cholesterol content compared to gallstones from children with hemolytic disease.
- Cholelithiasis was confirmed surgically in these pediatric patients.
Conclusions:
- Wilson disease patients are at increased risk for developing cholesterol-rich gallstones.
- Routine screening for gallstones is recommended in young patients diagnosed with Wilson disease.
- Cholelithiasis should be considered in the differential diagnosis of abdominal pain in pediatric Wilson disease cases.
Abstract:
We have studied three children with Wilson disease who had clinical symptoms suggestive of cholecystitis as well as radiologic evidence of gallstones, subsequently proven at the time of laparotomy. The gallstones from the patients with Wilson disease had an appreciably higher content of cholesterol than gallstones from age-matched children with hemolytic disease. Since gallstones may be present for years before they produce clinical symptoms, young patients with Wilson disease should undergo routine investigation for the presence of stones; cholelithiasis should also be considered in the differential diagnosis of abdominal pain in such patients.
