Background & Aim: There is currently no agreement on the screening strategy for non-alcoholic fatty liver disease (NAFLD) in children at risk. The North American Society for Pediatric Gastroenterology, Hepatology and Nutrition (NASPGHAN) recommends screening for NAFLD using alanine aminotransferase (ALT) in obese/overweight children, while the European Society for Pediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) recommends using both ALT and abdominal ultrasound. The aim of this study was to assess the prevalence of suspected NAFLD in obese children based on the 2 screening strategies. Method: Consecutive overweight/obese children seen at a weight-management program were included. Each child underwent a liver ultrasound and had ALT level measured at first visit. Two screening strategies were compared: the NASPGHAN strategy using ALT >2x the gender specific cut-off and the ESPGHAN strategy using elevated ALT >45 IU/L and/or fatty liver on ultrasound. Univariate and multivariate analyses were performed to assess predictors of low ALT in individuals with evidence of suspected NAFLD on ultrasound. Results: Overweight/obese children were included. NAFLD was suspected as follows: 26% based on the NASPGHAN strategy, and 58% based on the ESPGHAN strategy. Fatty liver was present on ultrasound in 53% of our cohort. ALT was >2x the gender specific cut-off in only 26% of children with fatty liver on ultrasound. Univariate and multivariate analyses indicated that children with fatty infiltration on ultrasound and low ALT were less likely to have metabolic syndrome, insulin resistance, or hypertriglyceridemia. Conclusion: By relying on ALT values alone to screen for NAFLD, suspected NAFLD might be missed in many children who are at risk. Children with fatty infiltration on ultrasound and low ALT may be less likely to have metabolic syndrome, insulin resistance or hypertriglyceridemia. (C) 2019 The Author(s).
