Paediatric liver disorders in Singapore

Area of Science:

• Pediatric Hepatology
• Childhood Liver Diseases
• Gastroenterology

Background:

• Infant and child livers are susceptible to adult pathologies, with distinct prevalence and etiological factors.
• Genetic metabolic disorders (e.g., galactosemia, phenylketonuria) and neoplasms (e.g., hepatoblastoma, hemangioma) frequently manifest in newborns.
• Acquired conditions like hepatitis and biliary atresia, along with Reyes encephalopathy and choledochal cysts, present unique challenges in pediatric liver care.

Purpose of the Study:

• To provide a comprehensive overview of liver pathologies in infants and children.
• To highlight differences in prevalence and causes compared to adult liver diseases.
• To discuss the diagnosis and management of specific pediatric liver conditions.

Main Methods:

• Review of common and significant liver diseases in the pediatric age group.
• Discussion of genetic, neoplastic, and acquired liver lesions.
• Exploration of conditions like Reyes encephalopathy, choledochal cysts, portal hypertension, and hepatic fibrosis.
• Consideration of specific etiologies such as beta-thalassemia and tropical liver infections.

Main Results:

• Genetic metabolic disorders are prominent in newborns, alongside neoplasms like hepatoblastoma and hemangioma.
• Hepatitis and biliary atresia are key acquired lesions requiring careful differentiation and management.
• Reyes encephalopathy, choledochal cysts, portal hypertension, and congenital hepatic fibrosis represent significant pediatric liver concerns.
• Certain tropical liver diseases are now rare in developed settings like Singapore.

Conclusions:

• Pediatric liver disease encompasses a broad spectrum from congenital to acquired conditions.
• Early diagnosis and appropriate management are crucial for favorable outcomes in children.
• Understanding the unique epidemiological and etiological profiles of pediatric liver diseases is essential for effective clinical practice.
