Advances in paediatric nonalcoholic fatty liver disease: Role of lipidomics

Area of Science:

• Pediatric Gastroenterology
• Metabolic Disorders
• Lipidomics

Background:

• Nonalcoholic fatty liver disease (NAFLD) is a growing global health concern, particularly in children, closely associated with obesity.
• The "multiple hits" theory suggests hepatic lipid accumulation and insulin resistance are key drivers of liver injury in NAFLD.
• Lipotoxicity, involving various lipid classes like sphingolipids and ceramides, plays a significant pathogenic role.

Purpose of the Study:

• To provide a comprehensive overview of the current lipidomic landscape in pediatric NAFLD.
• To highlight the pathogenic role of specific lipid classes in childhood NAFLD.
• To explore novel therapeutic strategies targeting lipid alterations for NAFLD prevention and treatment.

Main Methods:

• Review of recent lipidomics studies focusing on pediatric NAFLD.
• Analysis of lipidomic profiles in the context of NAFLD pathophysiology.
• Synthesis of evidence on the role of distinct lipid species in liver injury.

Main Results:

• Lipidomics studies have identified specific alterations in lipid profiles associated with pediatric NAFLD.
• While plasma and liver findings may show some discrepancies, lipidomic data offer valuable insights into NAFLD pathogenesis.
• Distinct lipid species are emerging as potential indicators and therapeutic targets.

Conclusions:

• Lipidomic profiling provides novel insights into the complex pathophysiology of pediatric NAFLD.
• Targeting specific lipid species represents a promising therapeutic avenue for managing childhood NAFLD.
• Understanding lipid alterations is crucial for developing effective NAFLD prevention and treatment strategies.
