Borger Ophir , Oren Asaf , Perl Liat , Yackobovitch-Gavan Michal , Sheppes Tamar , Brener Avivit , Elkon-Tamir Erella , Israeli Galit , Segev-Becker Anat , Lebenthal Ophir Yael

Context: Given the importance of sex hormones in metabolic regulation, dynamics in body composition and cardiometabolic alterations may occur in transgender persons receiving gender-affirming hormone (GAH) therapy.Objectives: Our aim was to explore the association between muscle-to-fat ratio (MFR) and the risk for metabolic syndrome components in transgender youth.Methods: In 71 tr...

Ben Simon Asaf , Uretzky Adi , Yackobovitch-Gavan Michal , Segev-Becker Anat , Midlij Eyas , Borger Ophir , Laurian Irina , Dorfman Anna , Brener Avivit , Lebenthal Yael

Context: Premature adrenarche (PA) could pose an increased risk of obesity and metabolic derangements in adolescence and early adulthood. However, little is known about the body composition of children with PA and its association to the development of adverse metabolic outcomes.Aim: To describe the body composition of children with PA and explore the interaction between PA and metabolic syndrome components.<p class="...

Exploring the Relationship between Muscle-to-Fat Ratio and Surrogate Markers of Nonalcoholic Fatty Liver Disease in Children with Overweight and Obesity

Background: We previously reported on the strong predictive value of the muscle-to-fat ratio (MFR) z-score in the development of early-onset metabolic syndrome components in children with overweight/obesity. Data on the role of the balance between muscle and fat in the development of childhood onset nonalcoholic fatty liver disease (NAFLD) are sparse. In the current study we explored the interplay between MFR and surrogate markers of NAFLD in children with ove...

Leri-Weill Syndrome Phenotype with Atypical Cytogenetic Finding

Mladenov Vilhelm , Iotova Violeta , Angelova Lydmila , Stoyanova Milena , Bogdanova Viktoria

Introduction: Leri-Weill dyschondrosteosis (LWD) is caused by haploinsufficiency of the SHOX gene, located in the pseudoautosomal region (PAR 1) of the short arm of the X and Y chromosomes. The gene is expressed in highest levels in bone tissue and its product likely controls the chondrocyte apoptosis. Deletions and duplications are most frequent, point mutations are responsible for minority of the cases. The main clinical symptoms of LWD include disproportionate short stature...

15-Year Old Girl with APS Type IIIc, with Post-Thymectomy Remission – Case Report

Bossowski Artur , Jamiolkowska Milena , Furmaniak Jadwiga , Smith Bernard Rees

Background: Autoimmune polyglandular syndromes (APS) is a group of heterogeneous conditions characterized by the association of at least two organ-specific disorders, concerning both endocrine and non-endocrine organs. On the basis of the clinical features, they are divided into four main types. Type III is defined as the combination of autoimmune thyroid disease and other autoimmune condition – divided into subtypes A, B and C.Objective and hypothe...

Chronic Inappropriate Antidiuresis in Childhood: Experience with Tolvaptan

Gaudino Rossella , Piona Claudia , Morandi Grazia , Cavarzere Paolo , Brugnara Milena

Background: The syndrome of inappropriate antidiuresis (SIAD) is one of the most common causes of hyponatremia: it’s a disorder of sodium and water balance, characterized by urinary dilution impairment and hypotonic hyponatremia, in the absence of renal disease or any non-osmotic stimulus, able to induce antidiuretic hormone (ADH) release. SIAD can be manifestation of a wide range of diseases, including cancer, head trauma, hydrocephalus and epilepsy. Usually transient an...

ACAN gene mutation in a patient born small for gestational age with familial short stature

Iotova Violeta , Deyanova Yana , Stoyanova Milena , Hachmeriyan Mari

Introduction: Aggrecan, encoded by the ACAN gene, is an important component in the cartilage extracellular matrix. Mutations in the ACAN gene have been associated with idiopathic and familial short stature in the recent years. Bone age (BA) is often advanced, although it can be delayed or normal. Patients can have dysmorphic features like broad forehead, midfacial hypoplasia, prognathism, posteriorly rotated ears, broad and short thumbs. Bone and joint problem...

Background: WBS is a rare genetic disorder characterized by distinctive facial features, intellectual disability, cardiovascular anomalies, and infantile hypercalcemia.Objective and hypotheses: Majority of WBS cases occur sporadically, only five families with clinically confirmed WBS have been identified by molecular cytogenetic analysis. Here, we report on the three molecular cytogenetically confirmed familial WBS detected in a family with familial shor...

Body Composition in 10–15 Years Old Children Exposed to Pesticides Prenatally

Tinggaard Jeanette , Wohlfahrt-Veje Christine , Schmidt Ida M , Boas Malene , Husby Steffen , Main Katharina M , Skakkebaek Niels E , Jensen Tina K , Andersen Helle R

Background: Exposure to non-persistent pesticides may have an effect on prenatal growth and later risk of adiposity. Prenatal pesticide exposure has been found to be associated with lower birth weight and higher body fat percentage calculated from skinfolds at age 6–11 years. Body composition measured by using DXA in children prenatally exposed to pesticides has not previously been reported.Objective and hypotheses: To study the effects of prenatal ...

Diagnostic value of soluble LEPR levels in the serum of patients with disease-causing biallelic LEPR variants

Zorn Stefanie , Tews Daniel , von Schnurbein Julia , Flehmig Bertram , Pridzun Lutz , Wabitsch Martin , Malene IV , Chantana Yay , Khun Leang Chhun , Ban Manet , Tyla Martin , Ngee Lek

Introduction: The soluble leptin receptor (sLR) is the main binding protein of leptin in the serum. It reflects the amount of membrane-bound leptin receptors (LEPR) as the sLR is produced by proteolytic cleavage of the extracellular domain of membrane-bound LEPR. Low sLR but high leptin levels were measured in patients with severe obesity. In patients with monogenic obesity caused by biallelic LEPR variants, sLR levels were found to be either undetect...
