Background: A national database has been developed to register longitudinal data from all CAH children detected through neonatal screening from 2002 onwards. So far, data from 105 children have been registered (65% of Dutch CAH patients) to evaluate treatment and long-term effects in CAH.Aims: To evaluate height and weight in relation to medication used in the first 2 years of life.Methods: Biometric data and medication dosage were...

Background: Long-term outcome studies on bilateral testicular regression (BTR) are currently lacking, hampering counseling of patients and parents. Although a vascular origin was initially reported, recent studies revealed a genetic origin in a subset of patients (i.e. DHX37 gene variants). How this relates to patient outcomes remains unclear.Methods: Thirty-five patients with BTR were recruited in eight Belgian centers ...

Biphasic Glucocorticoid Rhythm in One Month Old Infants: Reflection of a Developing HPA-Axis?

Hollanders Jonneke J. , de Goede Paul , van der Voorn Bibian , Honig Adriaan , Rotteveel Joost , Dolman Koert , Kalsbeek Andries , Finken Martijn J.J.

Background: The hypothalamus-pituitary-adrenal (HPA) axis displays a diurnal rhythm, peaking in the morning and with a nadir at night. However, not much is known about the development of the HPA- axis, although strikingly some evidence suggests that a rhythm with a peak in the afternoon is already present antenatally. We aimed to describe HPA-axis activity at age 1 month as well as study possible influencing factors.Methods</stro...

Close Correlation between Salivary and Blood Steroids in Normal Boys: Salivary Testosterone Best Characterizes Male Puberty

Aims: The golden standard to characterize pubertal maturation is the analysis of steroid hormones in the blood. The aim of the investigation was to assess whether the analysis of salivary steroids is similarly able to characterize male pubertal development.Methods: The investigation included 165 normal boys (mean age 12.7±2.8 years, mean body mass index 19.6±4.2 kg/m2). Pubic hair stages were stratified by Tanner and testicular volum...

Background: Boys affected with Duchenne Muscular Dystrophy (DMD) have lower bone mineral density compared with unaffected boys.Objective and hypotheses: We sought to determine the effects on bone mineral density (BMD) of 1 year treatment with Risedronate and calcium/vitamin D supplementation vs calcium/vitamin D supplementation alone.Method: BMD was measured at spine and whole body. We obtained early morning fasting blood samples f...

Correlation of AR Expression and AR Transcriptional Activity in Cultured Human Genital Fibroblasts

Background: The androgen receptor (AR) is essential for the development of primary and secondary male characteristics and is activated by its ligand dihydrotestosterone (DHT). Reduced AR activity can cause undervirilization and infertility. We recently developed an assay to test AR function as a ligand-dependent transcriptional activator in human genital skin fibroblasts (GF). So far it is unclear, if AR expression levels correlate with AR function in the male external genital...

Transient Congenital Hyperinsulinism and Renal Fanconi Syndrome

Background: Congenital hyperinsulinism is the most common cause of persistent hypoglycaemia in early infancy. Mutations in the HNF4A gene lead to transient hyperinsulinism in early infancy and maturity-onset diabetes of youth (MODY1), later in life. Fanconi syndrome is a generalised dysfunction of the renal proximal tubule with a loss of glucose, amino acids, phosphate, low molecular weight proteins, bicarbonate and urate, causing growth failure and rickets in childho...

Growth-Related Characteristics of Patients <18 Years of Age with Congenital Adrenal Hyperplasia Due to 21-Hydroxylase Deficiency (21OHD): Real-World Evidence from the I-CAH Registry

Farrar Mallory , He Wei , Ali Salma R , Bryce Jillian , Lawrence Neil , Baronio Federico , Claahsen-van der Grinten Hedi L. , Bonfig Walter , Krone Nils , Yonan Chuck , Ahmed S. Faisal ,

Background: Classic congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency is a rare autosomal recessive condition characterized by cortisol deficiency and elevated ACTH secretion, resulting in excess androgen production. This exposure to excess androgens contributes to advanced skeletal maturation and reduced growth in puberty. Data from the I-CAH registry were analyzed to identify growth-related characteristics of children and adolescents with...

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: Prenatal dexamethasone treatment (Pdex) has been used since the 1980s to prevent virilization in female offspring suspected to have congenital adrenal hyperplasia (CAH). However, due to lack of strong evidence for its best practice as well as limited data regarding long term adverse effects, use of dex is highly controversial. This study reveals the current medical practice regarding Pdex in female fetuses at risk of CAH due to 21 hydroxylase defic...
