Background: Primary adrenal insufficiency (PAI) is most commonly congenital in children. PAI is genetically heterogeneous with some gene defects causing syndromic disease. A third of patients have no genetic diagnosis meaning their prognosis is uncertain. We recently investigated families with a novel combination of PAI and steroid resistant nephrotic syndrome.Objective and hypotheses: To discover the genetic defect underlying this syndrome.<p class=...

Objective: Remission rates in young people with GravesÂ’ hyperthyroidism are 25% or less after a 2-yr course of thionamide antithyroid drug (ATD). Immunomodulatory agents could potentially improve outcome by facilitating immune tolerance. We wanted to explore whether rituximab, a B lymphocyte depleting agent, would increase remission rates when administered with a short course of ATD.Design: This was an investigator-...

Background: Primary ovarian insufficiency (POI) affects 1% of women and is associated with significant medical consequences. In approximately 10% of cases, POI presents early with absent puberty or primary amenorrhoea. A genetic cause for POI can be found in up to 30% of women. Identified genes often relate to the complex biological processes occurring in fetal life which underpin normal ovary development and function in later adulthood.Objective: We aim...

Introduction: The human adrenal gland originates from the adrenogonadal primordium at around 4 weeks post conception (wpc) and undergoes marked developmental changes throughout the first half of pregnancy. Several key aspects of adrenal maturation are well-established, such as the formation of a large inner fetal zone (FZ) and synthesis of dehydroepiandrosterone, but many other processes contributing to adrenal gland development and function in humans are stil...

Purpose: X-linked hypophosphatemia (XLH) is the most common hereditary cause of hypophosphatemic rickets. Elevated circulating levels of fibroblast growth factor 23 (FGF23) caused by mutations in the PHEX gene lead to renal phosphate wasting and rickets. Conventional treatment with phosphate salts and active vitamin D is associated with nephrocalcinosis in XLH patients. Mice on a high phosphate diet develop proximal tubular injury. Detailed analysis on kidney ...

Introduction: Ovary development was once considered a largely passive process. RNA sequencing (RNAseq) approaches have allowed us to begin to characterise ovary development in previously unparalleled detail, revealing the process to be complex and, still, little understood. A challenge is synthesising and using these data to advance our understanding of clinical disease. Through a clinically-focused lens, we elucidate novel aspects of the transcriptional lands...

Non-Invasive Measurements of Central Blood Pressure with Arterial Stiffness Indicators as a New Research Tool for Predicting Cardiovascular Risk in Children with Type 1 Diabetes Mellitus and Obesity

Noiszewska Klaudyna , Puchalski Mateusz , Skolimowska Anna , Bossowski Artur

Introduction: The main problem of contemporary diabetology is to prevent chronic complications of carbohydrate metabolism disorders according to DM1 and obesity (pre-disposing for DM2). The task is to find simple tools that allow rapid identification of vascular lesions and early treatment intervention.Aim of the study: The aim of the study was to evaluate parameters of CBP in patients with DM1 and obesityMaterials and methods: The...

Non-Medicament Treatment of Severe Obese Children, Using the One-Year Courses

Zagrebaeva Olga , Solntsava Anzhalika , Yemelyantsava Tatsiana

Background: It is hard to treat severe obese children only with diet and physical activity, psychological interventions are need.Objective and hypotheses: To examine the differences between courses of non-medicament treatment of severe obese children.Method: We examined 32 pubertal severe obese children BMI 31.2±0.8 kg/m2, 13.5±0.3 years. The newel (in Belarus) course of non-medicament treatment of obesity (die...

Background: Microcephalic primordial dwarfism (MPD) is a group of rare genetic disorders defined by severe growth restriction of both prenatal and postnatal weight (W), height (H), and particularly head circumference (HC).Objective and hypotheses: To elucidate the genetic origin of the MPD in dizygotic twins.Method: Exome sequencing of 19 genes known to be implicated in microcephaly was performed.Results: Diz...

Role of Mast Cells in the Establishment of the Mineralocorticoid Pathway in the Developing Mouse

Naccache Alexandre , Louiset Estelle , Lamaziere Antonin , Thomas Michael , Arabo Arnaud , Lefebvre Herve , Castanet Mireille

Mast cells are known to control mineralocorticoid synthesis and secretion in human normal adrenal gland and aldosterone-producing adenomas through release of serotonin. We recently detected these immune cells in human fetal adrenal from 18 weeks of gestation in the subcapsular layer, in correlation with the expression of steroidogenic enzymes required for aldosterone biosynthesis. This observation suggests the implication of mast cells in the mineralocorticoid synthesizing pat...
