Background: Current reference values for leptin in childhood and adolescence are presented separately for girls and boys, and as a function of age without considering the variability of fat mass. This complicates the interpretation of measured serum leptin concentrations since fat mass is the major determinant of circulating leptin concentrations. To fill this gap, we aimed at pooling existing data (age, BMI, sex, tanner stage (TS), serum leptin concentrations...

Aim: Childhood obesity has become extremely important issue worldwide. The aim of this study was to determine associations between data from bioimpedance analysis with the antrophometric measurements and biochemical results obtained from children and adolescents with severe obesity.Study population and Methods: Study group consisted of 128 children recruited in four regional reference centers including 70 girls (54.7%) a...

It is estimated that 1-5% of children and adolescents in Europe suffer from severe obesity (corresponding to an adult BMI > 40 kg/m2). However, in risk stratification, the occurrence of metabolic complications is more important than BMI itself. The study aimed to assess the occurrence of cardiovascular risk factors in a cohort of children and adolescents with severe obesity.Patients and Methods: The analysis included 140 patients (75 ...

Background: Fatty liver disease in children and adolescents is the most common cause of chronic liver disease in many countries. Criteria for a diagnosis of pediatric metabolic associated fatty liver disease (MAFLD) are based on hepatic steatosis in ultrasound, blood biomarkers or liver biopsy in association with one of the three criteria: excess adiposity (overweight, obesity or abdominal obesity), prediabetes or type 2 diabetes, or evidence of metabolic dysr...

Severe early-onset obesity (SEOO) increases the likelihood of obesity persisting into adulthood. Leptin (LEP), a hormone primarily produced in adipose tissue, plays a crucial role in regulating energy balance. When assessing young children with SEOO, it is important to consider abnormalities in the leptin-melanocortin pathway. Our study aim ed to identify children with SEOO who may have LEP deficiency or biologically inactive leptin by analyzing leptin and biologically active ...
