Background and aims: The low dose short corticotropin test (LCT) is the most frequently used test to diagnose glucocorticoid-induced adrenal insufficiency (GAI) in children. Result of the LCT must be interpreted with caution since stimulated peak cortisol (PC) thresholds depend on the assay and time of sampling. We evaluated the prevalence of GAI by the LCT using both 20 and 30 minutes sampling and cortisol measurements by the most recent Roche Elecsys Cortiso...

Background/ Aims: Hyperuricemia (HU) is a frequent finding in childhood obesity, ranging between 12 and 40%, and associates to a variable extent with different components of the metabolic syndrome (MS). In this study, the effect of gender, (a Belgian native vs a non-Belgian native) descent and degree of general and central adiposity on serum uric acid (SUA) and the prevalence of HU was investigated in a multi-ethnic population of overweight/obese children and ...

Background: Resistance to thyroid hormone (RTHβ) is a rare disease caused by an inactivating mutation in the thyroid hormone receptor beta gene (THRB). This condition leads to elevated thyroid hormone levels with non-suppressed TSH levels. The clinical phenotype is highly variable, ranging from asymptomatic to signs of hyperthyroidism and/or hypothyroidism. This study analysed the genotype and phenotype of paediatric and adult patients followed in three B...

Background & aim: Biallelic thyroglobulin (TG) gene variants can cause congenital hypothyroidism (CH), usually presenting with neonatal goiter and permanent in duration. In cases where biallelic truncating TG variants are present, serum TG levels are undetectable, while monoallelic or biallelic missense mutations manifest with circulating TG. Here, we present a case of transient CH resulting from TG deficiency, stemming from compound heterozygosity for a m...

Background: Activation of the renin-angiotensin-aldosterone system, hyperinsulinemia, and hyperleptinemia have been implicated in the pathogenesis of obesity-related arterial hypertension (AH). We therefore studied serum renin, aldosterone, leptin, and insulin levels in overweight and obese children with and without AH.Methods: 129 (77 male) overweight/obese (BMI z-score > 1.3 / > 2), children and adolescents, seek...
