OBJECTIVE: Metabolic dysfunction-associated steatotic liver disease (MASLD) is the most common chronic liver disease in children and is linked to type 2 diabetes. This study evaluates whether longitudinal changes in liver chemistries-γ-glutamyl transferase (GGT), aspartate aminotransferase (AST), and alanine aminotransferase (ALT)-can serve as biomarkers of increased type 2 diabetes risk in children with MASLD.
RESEARCH DESIGN AND METHODS: This multicenter longitudinal cohort study followed 1,035 children with biopsy-confirmed MASLD, without type 2 diabetes at baseline, for a mean of 3.9 years. Liver chemistries were measured annually, and type 2 diabetes was diagnosed based on fasting glucose, HbA1c, and clinical diagnosis. Extended Cox models with inverse probability weighting were used to evaluate associations between liver enzyme trajectories and type 2 diabetes risk.
RESULTS: The cumulative incidence of type 2 diabetes was 12.3%. Increases in GGT (hazard ratio [HR] 1.55; 95% CI 1.34-1.80), AST (HR 1.31; 95% CI 1.20-1.43), and ALT (HR 1.13; 95% CI 1.07-1.20) were associated with a higher risk of developing type 2 diabetes in the independent models. In the mutual model with all three liver chemistries, only GGT and AST remained significant.
CONCLUSIONS: A 30-unit increase in GGT over time was associated with a substantially higher risk of developing type 2 diabetes in children with MASLD. Together with AST, GGT may provide clinicians with concrete, routinely available parameters to monitor for early risk stratification. Further validation in independent cohorts is needed to confirm these findings and inform clinical application.
