Background: Hypophosphatemic rickets (HR) comprises a group of inherited forms of rickets characterised by renal phosphate wasting. Taking info account the latest advances in HR therapy, it now becomes of interest to better define the mutational and phenotypic spectra of disease.Objective and Hypotheses: The aim of this study was to clinically characterize and perform genetic analysis of 168 cases with HR.<p class="a...

Homozygous loss-of-function mutations of the calcium-sensing receptor gene (CaSR) are associated with neonatal severe hyperparathyroidism (NSHPT), a life-threatening condition with a challenging treatment approach.We report a 7-day-old-female infant who was admitted to our Pediatric Department due to poor sucking. On examination she was lethargic and hypotonic. Laboratory evaluation revealed extreme hypercalcemia of 23.54 mg/dL (N: 7.6–10.4...

Background: Zinc transporter 8 autoantibodies (ZnT8Abs) together with glutamic acid decarboxylase autoantibodies (GADAbs), insulinoma antigen 2 autoantibodies (IA-2Abs) and insulin autoantibodies (IAbs) are markers of type 1 diabetes mellitus (T1DM). We studied the prevalence of ZnT8Ab in children with autoimmune thyroid diseases (AITDs) to assess the association of AITDs and T1DM at the serological level.Methods: The st...

Background: The initiation of puberty is orchestrated by the augmentation in the secretion of gonadotropin-releasing hormone (GnRH) from a few thousand neurons located in the hypothalamus. Recent findings identified that the neuroendocrine control of puberty is regulated by a network of transcriptional factors hierarchically organized, but this still remains not fully elucidated. Enhanced At Puberty 1 (EAP1) is one of the main regulators of pubertal onset and it is ex...

Context: Growth analyses have traditionally been done by either non-structural descriptive statistics or by fitting models. While we usually describe height and weight separately, we assume reciprocity of weight and height on each other. We utilize ML to predict ages 7–18 y height based on height and weight data up to age 6y.Methods: After pre-processing the height and weight, primary and secondary features (height SDS, BMI, growth velocity) of 1596...

Background: Somapacitan is a reversible albumin-binding growth hormone (GH) derivative in clinical development for once-weekly administration in patients with GH deficiency (GHD). Clinical data in healthy subjects, and adults and children with GHD showed that once-weekly somapacitan injections were well tolerated with no clinically significant safety or local tolerability issues. A sustained dose-dependent IGF-I response supports a once-weekly treatment regimen.<p class="a...

Acute lymphoblastic leukemia (ALL) is the most prevalent cancer in childhood. Over the past decades, survival rates increased, but relapse is still associated with a poor prognosis, especially if the bone marrow (BM) is affected. Marrow adipose tissue (MAT) constitutes a major part of the BM niche, but its impact on normal hematopoiesis versus leukemia initiation, progression and relapse has only recently gained attention. MAT is very sensitive to changes in the patient’s...

Introduction: Glucagon-like peptide 1 (GLP-1) receptor agonists have been successfully used in adults with hypothalamic obesity, showing a BMI decrease and metabolic profile improvement. Data on GLP-1 receptor agonist treatment for children and adolescents is limited. Herein, we present a clinical case of a male adolescent treated with GLP-1 receptor agonist for hypothalamic obesity, secondary to craniopharyngioma.Case report: A 15.8 year-old boy (Height...

Background: Nutrient deprivation during early development has been associated with the predisposition to metabolic disorders in numerous epidemiological studies. Experiments with rodents also indicate a developmental plasticity of neuropsychological characteristics following alterations of early postnatal nutrition.Objective: Considering its interaction with metabolism and regulation of appetite and behavior, the endocannabinoid system (ECS) may represen...

Background: Aberrations in the timing of puberty may result in significant adverse health outcomes, including cancers, cardiovascular and neurological pathologies. Self-limited delayed puberty (DP) (i.e. constitutional delay of puberty) runs in families with either autosomal dominant or complex inheritance patterns in >70% of families, indicating a strong genetic basis of the trait. However, only a few genes have been identified underlying DP so far....
