Background: Type 2 diabetes (T2D) is an emerging disease in the pediatric population. T2D is associated with metabolic-associated fatty liver disease (MAFLD). High-density lipoproteins (HDLs) are lipoproteins that are believed to have atheroprotective properties that reduce the risk of cardiovascular disease (CVD). Current evidence suggests that the physicochemical and functional features of HDLs may play a key role in the pathogenesis of atherosclerosis.<...

The growth hormone (GH)-insulin-like growth factor (IGF-1) system is essential for optimal human growth and energy homeostasis. Deficiency of pregnancy-associated plasma protein-A2 (PAPP-A2), a protease involved in the liberation of free IGF-1, leads to problems in growth and bone density in humans and mice. Patients with PAPP-A2 deficiency also present lower body mass and mild glucose intolerance. The present study aimed to determine the influence of 1 month of high carbohydr...

The survival rate of young patients with cancer has greatly improved in the last decades, in part due to the introduction of new therapeutic agents and protocols.Chemotherapy may be associated with risk of ovarian dysfunction, permanent or transient amenorrhea, symptoms of ovarian insufficiency and infertility.It has been suggested that prepubertal ovary is less susceptible to deleterious effect of chemotherapy.<p class="abstex...

Introduction: Differences of sex development (DSD) encompass a variety of conditions with atypical development of chromosomal, gonadal or anatomic sex. 46, XX ovotesticular (OT) DSD is a rare condition, in which the presence of testicular and ovarian tissues is identified in the same individual. These patients present variable phenotypes with a wide spectrum of atypical genitalia and their sex assignment can be male or female. Short stature is a frequent issue...

Abstract: Congenital hyperinsulinism (CH) is the most frequent cause of persistent hypoglycemia in the newborn. Octreotide, a long-acting somatostatin analogue (SSA), is a second line treatment for diazoxide unresponsive CH patients. Although it has been found to be a safe and effective treatment, long-term benefits and side effects have not been thoroughly evaluated. Furthermore, some authors have emphasized that exocrine pancreatic insufficiency is a common ...

Background: Autoimmune diseases (AIDs) have familial aggregation and frequently share a common genetic background, but few studies have evaluated autoimmune clusters in children with AIDs and their families.Objective and hypotheses: To identify clusters of AIDs in children and their first-degree relatives.Method: A cross-sectional study was performed in subjects with an AID of pediatric onset (<18 years) recruited at Pediatric ...

Background: Hypothalamic obesity (HyOb) is a disease characterized by weight gain resistant to lifestyle changes and dietary restriction. The main clinical findings are hyperfagia and decline of satiety, high levels of insulin and an increase of adipogenesis. The major problem for these patients is that conventional treatments, either medical or surgical are not succesful and have variable results.Objective and hypotheses: We aim to describe the natural ...

Background: French health authorities have developed a national program to organize outpatient care networks for the prevention and management of obesity in children and adolescents (Réseau de Prise en Charge de l’Obésité Pédiatrique (REPOP)). To date, REPOP Ile-de-France has more than 250 primary care physicians with dietitians, nurses, educators, and psychologists trained in the management of childhood obesity as part of a standard care pathway, work...

Introduction: Improvements in the treatment of acute lymphoblastic leukaemia (ALL) and non-Hodgkin lymphoma (NHL) have increased survival, with the consequent concern about the long-term effects that childhood chemotherapy may have on ovarian function. AMH constitutes an indirect, reliable biomarker of the ovarian reserve, useful for the assessment of cancer therapy-related ovarian damage.Aim: To evaluate small ovarian f...

Introduction: Classic congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21OHD) is a rare, autosomal disorder characterized by deficiency of cortisol and oftentimes aldosterone, elevated adrenocorticotropic hormone (ACTH), and excess androgen production. In a phase 2 study of adolescents with classic 21OHD, 14 days of treatment with the corticotropin-releasing factor type 1 receptor (CRF1) antagonist, crinecerfont, led to median percent red...
