Background and Objectives: N-terminal-pro hormone Brain Natriuretic Peptide (NT-proBNP) and hs-Troponin T (hs-TnT) are commonly used cardiac biomarkers despite lacking a deeper understanding about influencing parameters especially in the healthy pediatric population. We previously found associations between NT-proBNP and hs-TnT and a child´s age, sex, pubertal status, Body Mass Index (BMI) and serum lipid levels. Subsequently, we explored associations wi...

Background: Evaluation of glucose metabolism is currently based on 2 h glucose during an oral glucose tolerance test (oGTT) or fasting glucose and insulin or A1c, as these are the only parameters where cutoff values exist. This does, however, not adequately reflect the degree of hyperinsulinemia due to insulin resistance in obese children.Objective and design: From frequent glucose and insulin levels during an oGTT of 64 healthy lean children (aged 7.7&#...

Background/Objectives: Blood amino acid (AA) and acylcarnitine (AC) concentrations are informative on physiological and disease-associated changes in human metabolic pathways. Previously, AAs and ACs were examined as potential biomarkers or predictors of complex metabolic diseases in adults and children. However, there is still a lack of studies examining physiological AA and AC blood levels in healthy paediatric populations. We aimed to assess the intra-perso...

Context: Childhood obesity is supposed to affect growth and development in children but there is uncertainty with regard to dynamics and potential causes. We analyzed differences in age-related growth patterns of obese and normal-weight children and their association with circulating endocrine and metabolic factors.Objective/Design: In a large German childhood cohort from Leipzig including 7986 children (22793 data sets) we compared cross-sectional and l...

Background: The course of type 2 diabetes is more severe among children with obesity than among adults. Therefore, children at high risk for glycemic deterioration should be detected early enough to guide preventive (and interventional) clinical management.Methods: We established age- and puberty-specific reference values for 7 different indexes addressing the insulin response during oral glucose tolerance testing upon 4...

Background: Non-alcoholic fatty liver disease (NAFLD) represents one of the most common obesity complications and can progress to non-alcoholic stetohepatitis (NASH). NASH is associated with lower insulin like growth factor I (IGF-1) and IGFBP-3, however no data are available regarding the growth hormone (GH)-IGF-I axis in early stage of NAFLD, characterised by hepatic steatosis.Objective and hypotheses: We aimed to investigate the GH-IGF-1 pathway in a ...

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...
