Background: 5-α-reductase type 2 enzyme catalyzes the conversion of testosterone into dihydrotestosterone, a potent androgen responsible for male sexual development during the fetal period. From 2017 to 2019, a homozygous hg38_chr2:31529414 C>T variant in SRD5A2 gene have been identified in 3 unrelated patients with DSD 46,XY of Buryat origin. The variant has been previously reported in one patient from China (Song et al, 2019) and l...

Aldosterone deficiency and resistance: The different faces of renal salt loss

Laurer Elisabeth , Tischlinger Katharina , Montero-Lopez Rodrigo , Blaschitz Alexandra , Wimleitner Marlene , Hoertenhuber Thomas , Hoegler Wolfgang

Introduction: Heritable conditions causing aldosterone deficiency (hypoaldosteronism) or target-organ resistance (pseudohypoaldosteronism, PHA) can lead to life-threatening salt-wasting crises in early life. Prompt evaluation and correct interpretation of aldosterone and renin are crucial to guide differential diagnosis and further testing. Here we report on the similarities and differences of two neonates presenting with salt-wasting: Patient (P1) due to PHA ...

Correlations between the degrees of obesity and dyslipidemia in a pediatric population from Romania

Amalia Ioana Arhire , Papuc Teodora , Miruna Sanziana Chiper , Chiriac Malina , Stoica Alexandra , Tambrea Elena

Keywords: pediatric obesity, metabolic syndrome, dyslipidemia, abdominal obesity, cardiovascular risk.Introduction: The prevalence of pediatric obesity is rising globally as well as in Romania and so are the complications of obesity. Dyslipidemia is one of the most frequent complications and is associated with cardiovascular risk even in children or teenagers. Evaluating the degree of obesity and the correlations between...

Early treatment of neonatal diabetes with oral glibenclamide suspension (Amglidia®) in an extremely preterm infant: evidence for efficacy, safety and easiness.

Background: Early treatment of neonatal diabetes with sulfonylureas has shown to improve neurodevelopment, beyond the demonstrated efficacy on glycemic control. Several barriers still prevent its use as an early treatment in preterm babies including the limited availability of a suitable galenic form of glibenclamide. Recently, an oral suspension of glibenclamide (Amglidia®) has been approved for use in EU.Methods: W...

Mast Cells in Human Adrenal Gland During Fetal Development

Naccache Alexandre , Duparc Celine , Louiset Estelle , Lefebvre Herve , Castanet Mireille

Background: We previously found that mast cells are present in the human adult adrenal gland with a possible role in the regulation of aldosterone secretion in both physiological conditions and aldosterone-producing adrenocortical adenomas responsible for primary hyperaldosteronism.Objective and Hypotheses: The aim of the present study was to investigate the presence of mast cells in the human fetal adrenal gland, and to provide arguments in favor of the...

Value of Alkaline Phosphatase Assay in Short Stature Exploration

Naccache Alexandre , Gayet Claire , Wieliczko Marie Claire , Castanet Mireille

Background: Short stature is a common reason for pediatric endocrinologist consultation, but in many cases, no cause can be identified. Childhood hypophosphatasia has widely variable clinical features from short stature to low bone mineral density with skeletal deformities, and the place of serum alkaline phosphatase (ALP) activity assay could be raised as etiological exploration is not consensualObjective and hypotheses: The aim of our study was to eval...

An Unusual Presentation of Isolated ACTH-Deficiency Secondary to TBX19 Mutation Revealed by Late Onset Hypoglycemia Seizure

Valentin Cecile , Saveanu Alexandru , Beltrand Jacques , Netchine Irene

Background: Congenital isolated ACTH deficiency (IAD) is a rare inherited disorder that is clinically and genetically heterogeneous. Patients are characterized by low or absent cortisol production secondary to low plasma ACTH despite normal secretion of other pituitary hormones and the absence of structural pituitary defects. Mutations in the TBX19 gene, a T-box factor selectively expressed in developing corticotroph cells, have been identified so far only in cases of neonatal...

High-Throughput Untargeted Plasma Metabolomics Unravels Gender Dimorphic Metabolic Trajectories in Naturally Conceived and ICSI Prepubertal Children

Background: Accumulating evidence has indicated that assisted reproductive technologies (ART) influence the metabolic physiology of the offspring, with a higher predisposition to metabolic disorders. Long-term metabolomic studies that separately consider males and females conceived with intra-cytoplasmic sperm injection (ICSI) vs naturally conceived (NC) children are needed. Previously, we had reported that ICSI-conceived prepubertal girls exhibit significant alterations in th...

Background: Oxidative stress and adipocytokines are associated with obesity.Objective and hypotheses: To investigate the association of adipocytokines with markers of pro- and anti-oxidation at baseline and their change and correlations during acute aerobic exercise in normal weight and obese pre- and early-pubertal boys.Method: Fifty healthy pre- and early-pubertal, normal weight and obese boys, underwent a baseline blood sampling...

Reference intervals of serum estradiol during childhood: comparing and reviewing five studies, effects of gender and age

Lamprecht Tabea , Reinehr Thomas , Kleber Michaela , Rothermel Juliane , Schulz Esther , Simic-Schleicher Gunter , Heger Sabine , Holterhus Paul-Martin , Kulle Alexandra

Background: Specific measurement of low serum / plasma concentrations of 17β-estradiol (E2) is important in pre-pubertal and pubertal children in routine paediatric endocrinology. However, there is still a gap in available reference intervals (RIs) for E2 in paediatrics. The study was partially funded by the German Ministry of Health, grant number 2519FSB503.Objective: First, we technically developed a highly sensit...
