Background: Pubertal induction in girls with hypogonadism through estrogen replacement therapy (ERT) aims at the development of secondary sexual characteristics, cognitive functions, uterine growth and maturation, bone mass accrual and linear growth. To date, the best induction regimen, capable of assuring both physiological gradual progression through Tanner stages and effective uterine development, is still to be established.Patients a...

Introduction: Obese children with normal glucose tolerance (NGT) but with 1-hour post-load plasma glucose (1hPG) ≥ 132.5 mg/dl are at higher risk of developing type 2 diabetes (T2D) and cardiometabolic complications. In addition, new markers of systemic inflammation derived from blood cell count could be used as indicators of insulin resistance, thus predicting worse metabolic profile.Objective: The aim of our study w...

Background: COVID-19 restriction measurements have determined profound alterations in glucose and insulin metabolism in children with overweight and obesity. However, to date few data have explored the effects of the relaxation of restrictions in the pediatric population. Thus, we compared anthropometric and OGTT data in children with overweight and obesity during the two years after (2021-2023) compared to the two years during (2020-2021) and before (2018-201...

Introduction: PMM2-CDG is the most common congenital disorder of glycosylation (CDG). Since glycoproteins are involved in every endocrine axis, PMM2-CDG patients have a high risk of developing endocrinopathies.Case report: We describe two 12 years-old female PMM2-CDG patients with severe short stature and no clinical sign of puberty. One patient showed low serum levels of insulin-like growth factor-1 (IGF-1) and IGF bind...

Non-autoimmune hypothyroidism is characterized by high serum TSH level, normal or low thyroid hormones, absence of autoantibodies and normal or hypoplasic in situ thyroid gland. It is known that heterozygous mutations in the TSH receptor gene (TSHR) are associated with partial TSH resistance which clinically ranges from isolated hyperthyrotropinemia to non-autoimmune hypothyroidism. Despite this, an absence of mutations in the TSHR gene has been repo...

Background: Hypophosphatemic rickets (HR) associated with elevated FGF23 plasma levels is a disorder characterized by renal phosphate wasting, leading to impaired bone mineralization. Conventional therapy, based on oral phosphate and calcitriol, has limited efficacy and tolerability. In 2018, burosumab, a monoclonal antibody against fibroblast growth factor 23 (FGF-23), was approved for the treatment of X-linked hypophosphatemia (XLH). However, data on burosum...

Genetic obesity is rare and usually affects the hunger/satiety circuit. Monogenic obesity is mainly due to variants in genes of the leptin-melanocortin pathway which regulates the control of food intake. Melanocortin 4 receptor (MC4R)-linked obesity has been reported as one of the most common forms of monogenic obesity. Mutations in the MC4R gene have been described in 2-3% of obese children and adults with variable severity of obesity and no additional phenotype. Syndromic ob...

Background: Hypobetalipoproteinemias (HBL) is a heterogeneous group of disorders characterized by reduced plasma levels of total cholesterol (TC), low density lipoprotein-cholesterol (LDL-C) and apolipoprotein B (ApoB). Familial hypobetalipoproteinemia (FHBL) is the most frequent monogenic form of HBL with a dominant mode of inheritance. It may be due to loss-of-function mutations in APOB or, less frequently, in other genes. Heterozygous patients are often asy...

The measurement of serum FGF23 plays a pivotal role in the differential diagnosis of patients with hypophosphatemia. However, its interpretation may be difficult in some cases. We report the case of a child with rickets and severe hypophosphatemia, where both intact FGF23 (iFGF23), the active form, and C terminal FGF23 fragments (C-FGF23) were measured.Case report: A 5.7-year-old girl, born at term from first-grade-related Pakistani pare...

A was born at 38+4 weeks by eutocic delivery, with adequate auxological parameters and unremarkable perinatal history. She was admitted to our center at 15 days of life after the second screening for congenital hypothyroidism (CH) resulted positive (bTSH 48 mU/L); the first test was negative. Serum blood tests confirmed the diagnosis of CH (TSH 157 mU/L, FT4 0.96 ng/dl, FT3 8.44 pg/ml, negative thyroid autoimmunity). Thyroid ultrasound showed a gland of normal size. Therefore,...
