Background: Growth hormone (GH) has been shown to reduce insulin sensitivity in Turner girls, however a compensatory increase of insulin secretion by pancreatic beta cells usually occurs, probably stimulated by GH itself. Oral disposition index (ODI) express the capacity of beta cells to adapt to insulin sensitivity.Objective and hypotheses: To study longitudinally the insulin sensitivity (HOMA-S), the insulin secretion (IGI) and the ODI in a group of gi...

Background: GH has been shown to influence glucose homeostasis through a negative effect on insulin sensitivity followed by a compensatory increase of insulin secretion. However it has been recently reported, in animals and in humans, that GH might stimulate insulin secretion also through a direct effect on the growth and on the function of the pancreatic β cell.Objective and hypotheses: To study longitudinally the insulin sensitivity (HOMA-S), the ...

Introduction: Salt wasting is a potentially life-threatening condition in the newborn period. Other than 21 OH-CAH other rarer adrenal causes should be considered in the differential diagnosisObjective: To report the laboratory, clinical features, management and genotype of a series of consecutive patients who showed up at our Center for a salt wasting syndrome in the last 32 years, excluding patients with 21 OH CAH....

Introduction: in females with precocious thelarche (PT) (< 8 years), elevation of morning luteinizing hormone levels (mLH) may be indicative of pubertal activation of the pituitary gonadal axis. However, this approach could not be satisfactory in real life management of PT due to the risk of reduced specificity and sensitivity of the mLH thresholds. We propose a diagnostic flow-chart based on basal and stimulated gonadotrophins integrated with bone age and ...

Introduction: The gonadotropin releasing hormone stimulation test (GnRHST) is commonly used to screen CPP. Some recent studies reported that morning unstimulated luteinizing hormone levels may be sufficient to discriminate pubertal from prepubertal children. The aim of this study is to evaluate the clinical efficacy of mLH to screen CPP in femalesPatients and Methods: We retrospectively studied the clinical and hormonal ...

Background: The isodicentric Y (idic Y) is one of the most common aberrations of the Y chromosome. Most patients (pts) are chromosomal mosaics, including 45,X cell line.Objective and hypotheses: Our aim is to describe clinical and molecular features of our 45,X/46,Xidic(Y) cases.Method: We retrospectively evaluate the clinical description of nine cases (six females, one male, two with ambiguous genitalia) with mosaic karyotype 45,X...

Background: Final height (FH) in patients (pts) with congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21OHD) is often under the genetic target, despite improvement of new therapeutic strategies.Objective and hypotheses: The aim of this study is to evaluate FH in a cohort of pts with CAH due to 21OHD diagnosed before and after newborn screening (NBS) era in Emilia-Romagna, Italy.Method: We evaluated final heigh...

Background: Autoimmune polyendocrinopathy candidiasis ectodermal dystrophy (APECED) or autoimmune polyendocrinopathy type 1 (APS-1) is a rare monogenic autosomal recessive disease due to pathogenic variants in the AIRE gene. APECED usually begins during early childhood with chronic mucocutaneous candidiasis (CMC), followed by hypopathyroidism (HP) and Addison’s disease (AD); however, other endocrine and non-endocrine components may occur with a different prevalen...

Background: Differences of sex development (DSDs) (conditions with atypical development of chromosomal, gonadal or anatomic sex) are classified into three groups: sex chromosome DSD, 46,XYDSD and 46,XX DSD. Around 1 newborn in 5000 presents ambiguous genitalia with a major challenge for male or female assignment. The identification of a genetic cause can contribute to a correct diagnosis and to optimize both management and genetic counselling.<p class="abs...

Background: Familial glucocorticoid deficiency (FGD) is a rare and potentially life-threatening disease, characterized by adrenal insufficiency without mineralocorticoid deficiency. It is diagnosed during the neonatal period but also in childhood. Manifestations are recurrent hypoglycemia, seizures or even coma, chronic fatigue, recurrent infections and skin hyperpigmentation. Mutations on mineralocorticoid receptor 2 (MC2R) gene and on melanocortin-2 receptor accesso...
