Abstract

Abstract Background Non-alcoholic fatty liver disease is associated with obesity. A subclinical inflammation state, endothelial dysfunction, and parameters related to metabolic syndrome (MetS), have been documented in children with obesity. We aimed to determine the changes that occur in liver enzymes levels in response to the standard treatment of childhood obesity, also assessing any associations with liver enzyme levels, leptin, and markers of insulin resistance (IR), inflammation, and parameters related to MetS in prepubertal children. Methods We carried out a longitudinal study in prepubertal children (aged 6–9 years) of both sexes with obesity; a total of 63 participants were recruited. Liver enzymes, C-reactive protein (CRP), interleukin-6, neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), soluble intercellular adhesion molecule-1 (sICAM-1), leptin, homeostasis model assessment for IR (HOMA-IR), and parameters related to MetS were measured. Results After standard treatment for 9 months, children who lowered their standardised body mass index (SDS-BMI) had significantly lower systolic blood pressure (p = 0.0242), diastolic blood pressure (p = 0.0002), HOMA-IR (p = 0.0061), and levels of alanine aminotransferase (ALT) (p = 0.0048), CRP (p = 0.0001), sICAM-1 (p = 0.0460), and IL-6 (p = 0.0438). There was a significant association between the changes that occur with treatment, in the ALT levels, and changes in leptin (p = 0.0096), inflammation biomarkers [CRP (p = 0.0061), IL-6 (p = 0.0337), NLR (p = 0.0458), PLR (p = 0.0134)], and HOMA-IR (p = 0.0322). Conclusion Our results showed that a decrease in ALT levels after the standard treatment for 9 months was associated with favourable changes in IR markers (HOMA-IR) and inflammation (IL-6, CRP, NLR, and PLR).
