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...

Background: GH-secretion rates for children ranges in pre/early puberty 0.1–11 U/24 h and during mid-puberty 4–40 U/24 h. This can be used to optimize the rhGH treatment doses in children.Objective and hypotheses: To calculated the bioavailable rhGH in relation to injected dose and compare this to GH-secretory rate in healthy children; and to investigate factors influencing bioavailability.Method: One hundred and twenty e...

Background: We aimed to assess whether or not anthropometric indices such as weight circumference (WC), waist/hip ratio (WHR), waist-height ratio (WHtR), and weight for height (W/H) are predictors for metabolic syndrome (MetS) among obese children and adolescents. We aimed to describe effects of gender and pubertal status on these anthropometric indices.Method: A total of 291 obese children and adolescents (160 girls and 131 boys, age range: 6–16 ye...

Background: Subjects with impaired glucose tolerance (IGT) are at risk for type 2 diabetes mellitus (T2DM) and cardiovascular disease. The predictors of IGT in obese youth are not well described.Objective and hypotheses: We aim to evaluate insulin dynamics and biochemical markers for predicting IGT in Thai obese youth.Method: We studied 115 obese Thai children who underwent an oral glucose tolerance test (OGTT). Plasma glucose and ...

Background: GH deficiency (GHD) occurs due to different aetiologies, morphological abnormalities in pituitary, or mutations leading the individual to lose the genetic growth potential. The pituitary dysfunction can be as GHD alone or associated with other hormones deficiencies. Patients with abnormalities in pituitary may present a greater height loss than others and couldn’t reach the target height (TH) according to final height (FH).Objectives: To...

Introduction: Complete ALS deficiency (ALS-D), caused by inactivating mutations in both IGFALS gene alleles, presents severe IGF1 and IGFBP3 deficiencies associated to moderate growth retardation.Aim: To characterize the molecular defect in a family where the index case and his father presented short stature and IGF1 and IGFBP3 deficiencies.Methods: IGF1, IGFBP3, and GH serum levels were determined by CLIA, ALS by ELISA an...

Introduction: The reported occurrence and management of acute adrenal insufficiency (AI) – related adverse events (AE) vary widely between centres and may depend on available resources.Aim: To use the data within the I-CAH Registry to understand the association between the occurrence and management of AI related AE, their management and the availability of local resources.Methods:</st...

Introduction: Despite existing guidelines there is no unified approach to glucocorticoid and mineralocorticoid replacement in congenital adrenal hyperplasia (CAH). Consequently, treatment varies in adults and children as well as across countries.Objective: We used data from the I-CAH Registry to identify geographical and temporal variations in the treatment with glucocorticoids and mineralocorticoids of children and adul...

Introduction: Depending on the underlying diagnosis, Disorders of Sex Development (DSD) can be associated with an increased risk of germ cell cancers. To date, however, knowledge regarding the indications and timing of gonadectomy is lacking.Methods: The International-DSD (I-DSD) Registry was interrogated for anonymised information regarding the diagnosis, karyotype, sex of rearing and timing of gonadectomy, if undertaken, of all individuals of any karyo...

Background: Steroidogenic Factor 1 (NR5A1/SF-1) is essential for the development and function of human sex and steroid organs. Variants of SF-1 lead to a broad spectrum of phenotypes including adrenal insufficiency and differences of sex development (DSD), but data on the whole picture of phenotypes in individuals with SF-1 variants are currently lacking. We aim to investigate the phenotype of individuals with SF-1 variants in a large interna...
