V Zhukouskaya Volha , Ertl Diana-Alexandra , Berkenou Jugurtha , Audrain Christelle , Bardet Claire , Rothenbuhler Anya , Linglart Agnes

Background/aim: Hyperparathyroidism (HPHT) is a common feature in patients with X-linked hypophosphatemia (XLH) especially when treated with vitamin D analogues and phosphate supplements. Although the exact mechanism is not clear, it is assumed that phosphate supplements taken chronically stimulate parathyroid hormone (PTH) secretion. We prospectively assessed the effect of a novel pathogenetic treatment anti-FGF23 (burosumab) on PTH levels in children with XL...

Clinical and laboratory characteristics of arginine vasopressin resistance and high carrier frequency of a novel homozygous variant p.R113C in the AQP2 gene among Buryats

Makretskaya Nina , Nanzanova Ulyana , Hamaganova Irina , Eremina Elena , Filatova Alexandra , Skoblov Mikhail , Tiulpakov Anatoly

Background: Congenital nephrogenic diabetes insipidus (arginine vasopressin resistance) is a rare inherited disorder characterized by insensitivity of the kidney to the antidiuretic effect of vasopressin. About 90% cases nephrogenic diabetes insipidus is an X-linked recessive disorder caused by variants in the AVP V2 receptor gene (AVPR2). In the remaining cases (10%) the disease is autosomal recessive or dominant and, for these patients, variants in ...

High carrier frequency of a splicing c.589G>A variant in the SRD5A2 gene among Buryats

Makretskaya Nina , Nanzanova Ulyana , Kalinchenko Natalia , Hamaganova Irina , Eremina Elena , Filatova Alexandra , Skoblov Mikhail , Tiulpakov Anatoly

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...
