Introduction: Studies about pubertal onset and the menarcheal age in girls with the antecedent of idiopathic premature adrenarche (IPA) are limited and with discordant results. For these reasons, we created a cohort of girls with the diagnosis of IPA. The objectives of our study were: a) to know the age of pubertal onset; b) to evaluate menarcheal age; c) to determine the growth rate in the first two years after the IPA diagnosis; d) to collect adult height da...

Patients with autoimmune polyendocrinopathy candidiasis ectodermal dystrophy (APECED), develop autoantibodies to multiple self-proteins. The patients have high titer autoantibodies to multiple cytokines, most prominently to type 1 interferons and cytokines associated with Th17 cell functions. In addition to these signature autoantibodies, APECED patients develop autoantibodies to many other self-proteins characteristic to autoimmune diseases and display broad autoantibody repe...

Central hypothyroidism (CeH) can be defined as a lower than desirable secretion of thyroid hormone by a normal thyroid gland resulting from (quantitative or qualitative) insufficient TSH secretion. Causes are congenital and acquired functional or anatomic defects of the hypothalamus, pituitary gland or both. CeH can be difficult to diagnose, especially in children without a history of brain defects or brain damaging treatment (e.g. irradiation), and when plasma FT4 concentrati...

Flash glucose monitoring is now included in the Portfolio of Services of the Public Health System of Andalusia in Spain. We enrolled 145 paediatric T1D diabetes patients into a prospective, interventional study of the impact of the FreeStyle Libre system on HbA1c levels in this population, as well as additional measures of glycemic health, such as Time in Range (TIR) and Time Below Range (TBR). Subjects were trained in use of the FreeStyle Libre system at the start of the stud...

Background and aim: Metformin is widely used in Type 2 diabetes, with increasing reports of a potential bone protective role. We investigated the role of AMPK in mediating the effects of metformin on mesenchymal stem cell (MSC) differentiation to either osteoblasts or adipocytes.Methods: Confluent mouse MSCs (C3H10T1/2), wild type (WT) and AMPK knockout (KO) mouse embryo fibroblasts (MEFs) were treated with metformin(500 μM), AMPK-activator A769662(...

Introduction: The Body Mass Index (BMI) is an essential indicator for the nutritional assessment of children and reflects the exposure to health conditions that are harmful to the development of this population.Objective: To analyze the temporal trends of the BMI of Brazilian children aged 5-10 between 2010 and 2022.Patients and methods: Descriptive ecological study. Data obtained ...

Introduction: Protein tyrosine phosphatase non-receptor type 22 (PTPN22) is a well-established genetic locus of type 1 diabetes (T1D). The aim of the present study is to compare the methylation level of PTPN22 between children and adolescents of Greek origin with T1D and healthy controls.Patients and Methods: Twenty T1D participants and 20 age-/gender-matched healthy youngsters were enrolled. DNA was extracted from white blood cells, the...

Background: The male Hypothalamic-Pituitary-Gonadal (HPG) axis undergoes a transient activity phase during the first months of life with surging serum concentrations of reproductive hormones. Theoretically, the hormonal surge could represent a passive postnatal feedback to the withdrawal from the high sex steroid levels in pregnancy. However, we believe that minipuberty rather represents an active, tightly genetically-regulated biological process. We therefore...

Background: Patients with autosomal dominant hypocalcemia type 1 (ADH1), due to germline gain-of-function calcium-sensing receptor (CASR) mutations, have hypocalcemia and seizures, hyperphosphatemia, hypercalciuria and inappropriately low parathyroid hormone (PTH) concentrations. Treatment for ADH1 comprises calcium and vitamin D analogs, however, their use predisposes to nephrocalcinosis and renal impairment. In contrast, recombinant human PTH(1-34) may incre...

Background: In minipuberty, the male hypothalamic-pituitary-gonadal (HPG) axis is transiently activated triggering a surge in reproductive hormones causing growth of the genitalia. Longitudinal individual growth of the infant penis during minipuberty and associations to the HPG axis and IGF-I have not been thoroughly assessed.Aim: To describe the development of penile length and width as well as their relation to serum c...
