Deodati Annalisa , amodeo mariaelisa , mirra giulia , pampanini valentina , cianfarani stefano

Background: Congenital leptin deficiency is a rare cause of early-onset severe obesity. Clinical features of congenital leptin deficiency include early-onset severe obesity, marked hyperphagia, endocrine and metabolic alterations. Some patients have immune dysregulation.Case report: We describe two siblings from Libya referred for severe obesity. A boy (patient 1) referred at the age of 4 years and 3 months and a girl (p...

Prevalence of brain alterations in boys with isolated central precocious puberty

Amodeo Mariaelisa , Deodati Annalisa , Pedicelli Stefania , Pampanini Valentina , Cianfarani Stefano

Introduction: Brain magnetic resonance imaging (MRI) is routinely performed to identify brain lesions in boys with central precocious puberty (CPP). In contrast to girls, in whom more than 90% of cases are idiopathic, it has been reported that 4 up to 75% of boys with CPP have pathological brain lesions.Aim: to evaluate the prevalence of brain lesions in males with isolated CPP and to identify potential clinical and bioc...

Genetic bases of familial central precocious puberty

Khabibullina Dina , Kolodkina Anna , Bezlepkina Olga , Peterkova Valentina

Background: Nowadays, single nucleotide polymorphisms in genes KISS1, KISS1R, MKRN3, DLK1 have been described as the leading cause of precocious hypothalamic-pituitary axis activation in children. Genetic testing in patients with hereditary forms of precocious puberty (PP) can expand our knowledge in underlying molecular mechanisms of the disease. The diagnosis of genetic bases is necessary for genetic counselling.Aim: T...

Genetic and clinical heterogenicity in Russian adolescents with congenital isolated hypogonadotropic hypogonadism

Kokoreva Kristina , Chugunov Igor , Volevodz Natalia , Bezlepkina Olga , Peterkova Valentina

Background: Congenital isolated hypogonadotropic hypogonadism (СIHH) is a clinically and genetically heterogenous disorder characterized by absence or abnormal gonadotropin-releasing hormone secretion (GnRH). Adolescents with CIHH have complete or partial pubertal failure. Pathogenic variants in more than 60 genes have been associated with CIHH. CIHH can be complete, partial or reversal. Boys with CIHH may have micropenis and cryptorchidism. Except reprodu...

Clinical case of rare association of Treacher Collins syndrome with micropenis and unilateral cryptorchidism in Russian patient

Kokoreva Kristina , Pisareva Elena , Zyuzikova Zinaida , Volevodz Natalia , Peterkova Valentina

Objective: Treacher Collins syndrome (TCS) is rare autosomal dominant genetic condition characterized by the following features of the head and face: absence of the ears, down-slanting palpebral fissures, eyelid colobomas, microtia, bilateral choanal atresia and etc. Prevalence of TCS is from 1 per 25,000 to 1 in 50,000 live births. Most of TCS patients don’t have endocrine disorders that is why endocrinologists are not familiar with this condit...

Background: Endothelial dysfunction is a macrovascular complication of type 1 diabetes. Children and adolescents with type 1 diabetes may suffer of endothelial dysfunction, irrespective of chronological age and disease duration.Objective and hypotheses: After evaluating the prevalence of early endothelial dysfunction, as measured by mean of reactive hyperaemia in adolescents with type 1 diabetes, at baseline and after 1-year follow-up, we started a 6-mon...

Antoniotti Valentina , Colombo Alice , Mancioppi Valentina , Solito Arianna , Partenope Cristina , Petri Antonella , Rabbone Ivana , Ferrante Daniela , Prodam Flavia , Bellone Simonetta

Pediatric obesity is constantly increasing and exposes to serious cardiovascular and metabolic risks. The first treatment against obesity is lifestyle change. Actually, any intervention seems to be effective on the evolution of this condition, especially in the long term. For this reason, the interest in non-pharmaceutical compounds is growing. Several studies mentioned the use of zinc and inositol as compounds acting on weight loss and insulin resistance. The aim of this stud...

Hypoglycemia in Adolescence as the Presenting Sign of Familial MEN1

Justine Bailleul , Natacha Bouhours-Nouet , Valentine Suteau , Maryam Azgal , Marie-Neige Campas , Aurelie Donzeau , Regis Coutant

Multiple Endocrine Neoplasia Type 1 (MEN1) is an inherited autosomal dominant disorder caused by mutations in the MEN1 tumor suppressor gene. Penetrance increases with age. It combines mainly hyperparathyroidism, adenomas of the pancreas and pituitary gland. The prevalence is about 2/100 000. Diagnosis in children is rare except in the case of family screening. We report the diagnosis of a familial MEN1 whose index case was an adolescent girl investigated because of hypoglycae...

Glucose alterations, insulin resistance, hypertension, and activation of the renin-aldosterone system are strictly associated in pediatric obesity

Antoniotti Valentina , Amore Martina , Bellone Simonetta , Ricotti Roberta , De Grandi Roberta , Caputo Marina , Spadaccini Daniele , Mancioppi Valentina , Aimaretti Gianluca , Prodam Flavia

Background: The increase of global childhood obesity has led to an increase of associated co-morbidities also at a young age. The pro-inflammatory state and insulin resistance are two master regulators of several complications, including hypertension and pre-diabetes frequently connected in a complex crosstalk.Aim: To evaluate the relationship between glucose alterations and blood pressure and the pathogenetic involvemen...

Background: Fructose consumption in children is increasing, as is the prevalence of metabolic dysfunction-associated steatotic liver disease (MASLD). Despite the growing evidence supporting the effects of added sugars in the development of metabolic syndrome and related comorbidities, the association between fructose intake and liver diseases remains to be clarified, especially in young people. Our study aim ed to evaluate the role of fructose intake on metabo...
