Hypertransaminasemia in hospitalized children: Insights from a National Multicenter Study by the Italian Society of Pediatric Gastroenterology, Hepatology, and Nutrition.

Overall, the prevalence of hypertransaminasemia was 34.4% (n = 570).

The majority had mild to moderate liver enzymes elevation.

Positive correlation were found between aspartate aminotransferase and creatin P-kinase (creatin P-kinase), body mass index z-score and cholesterol.

At discharge, 298 of the 570 re-tested transaminases: 21.4% (64/298) had persistent combined elevation, 13.8% (41/298) isolated alanine aminotransferase, and 37.6% (112/298) isolated elevation.
