Introduction: Skeletal muscle plays a crucial role in glucose disposal, and studies have shown a positive relationship between muscle mass and insulin sensitivity. However, an elevated lean mass has also been associated with metabolically adverse outcomes. This study aimed to evaluate the association between the risk of metabolic syndrome (MetS) and lean mass using dual-energy X-ray absorptiometry (DXA) in a nationally representative sample from the Korea Nati...

Background: The hypothalamic–pituitary–adrenal (HPA) axis, and cortisol in particular, has been reported to be involved in obesity-associated metabolic disturbances in adults and in specific populations of adolescents.Objective and hypotheses: To investigate the associations between serum ACTH and cortisol levels and cardiovascular risk factors in obese children and adolescents.Method: Of 1119 obese children and adolescen...

Background: IGF1 is an important marker of GH treatment and is used to titrate the GH dose.Objective and hypotheses: We report the correlation between the GH treatment induced increase in IGF1 and growth improvement in short children born small for gestational age (SGA).Method: We recruited 13 pre-pubertal SGA children (eight boys, five girls) who received GH treatment. Eight continued treatment for >2 years. We retrospectively...

Background: Osteogenesis imperfecta (OI) is a genetic connective tissue disorder with variable phenotype, mainly characterized by bone fragility, short stature and non-skeleton findings. Since growth failure is a predominant feature of OI, recombinant human growth hormone (rhGH) has been suggested as a potential intervention. We describe two boys with OI type I treated with rhGH.Case Reports: Patient 1 had the first frac...

Background: We present a patient with co-existence of two rare conditions 3β-Hydroxysteroid dehydrogenase type 2 deficiency (HSD3B2) the rarest form of Congenital Adrenal Hyperplasia (CAH) and Bartter’s Syndrome (hypokalaemic alkalosis secondary to hyperaldosteronism).Case Report: A female infant (46XX) born at 34/40 weeks weighing 2.67 kg to non-consanguineous parents presented on day four of life with significant weight loss. Subsequent inves...

Background: The phosphatase and tensin homolog (PTEN)/phosphatidylinositol-3-kinase (PI3K)/AKT signaling pathway is central for cell cycle control, differentiation, migration, and metabolism. Unrestricted growth of adipose tissue in particular is frequently seen in humans with germline PTEN and mosaic activating PIK3CA mutations, respectively.Objective and hypotheses: We assume that adipocytes from affected tissue show hyperproliferation and modified dif...

Background: The phenotypic spectrum of short stature homeobox-containing gene deficiency disorders (SHOX-D) ranges from non-specific short stature to Leri-Weill dyschondrosteosis. Current guidelines support rhGH in SHOX-D children, but long-term data are still lacking. Moreover, no correlation has been established yet between the severity of phenotype, including the response to rhGH, and the underlying SHOX pathogenic variant.Aims: To ev...

Background: Controlling therapy of infants, especially from neonates onwards, with classic congenital adrenal hyperplasia (CAH) is challenging due to the lack of reference values.Methods: We retrospectively analyzed 158 spot urinary steroid hormone metabolite profiles determined by gas chromatography–mass spectrometry (GC-MS) of 60 infants aged 0–4.2 years with classic 21-hydroxylase deficiency (21-OHD) on hydr...

Background: Optimisation of hydrocortisone replacement therapy remains challenging due to complex pharmacokinetics as circulating cortisol is protein bound mainly to corticosteroid-binding globulin (CBG) that has a circadian rhythm.Objective: A detailed analysis of the CBG circadian rhythm and its impact on cortisol exposure during hydrocortisone replacement therapy.Methods: CBG was measured over 24 h in 14 healthy...

Background: Vitamin D deficiency in children clinically manifests as rickets causing growth impairment and bowing of the long bones, potentially increasing the ratio between crown-rump length and length (CRL:L) or sitting height and height (SH:H).Objective and hypotheses: We investigated whether CRL:L in 19-months-olds and SH:H in 36-months-olds were lower with higher cord 25hydroxyvitamin D (25OHD).Method: Participants were includ...
