Background: 25-Hydroxyvitamin D (25(OH)D) deficiency is reported to be common in patients with rheumatoid arthritis and associated with disease activity, physical disability, and cardiometabolic intermediates; data in patients with juvenile idiopathic arthritis (JIA) are inconsistent.Objective and hypotheses: To assess serum 25(OH)D in children, adolescents, and young adults with JIA, and to identify the risk factors for vitamin D deficiency in JIA patie...

Background: Dietary and lifestyle modifications commonly proposed to overweight or obese youth lack efficacy in those with severe obesity. Early results with bariatric procedures in obese adolescents suggest that weight loss and safety are comparable or better than those seen in adults. One of these procedures, laparoscopic sleeve gastrectomy, is commonly performed using multiple ports. We selected single port sleeve gastrectomy (SPSG) as a minimally invasive surgery to be tes...

Background: Fetuin A is a hepatokine known as a natural inhibitor of the insulin receptor tyrosine kinase and is associated with insulin resistance and nonalcoholic fatty liver disease (NAFLD). Studies on adults provided conflicting results regarding the link between fetuin A and the severity of liver damage in NAFLD. Data on children are limited.Objective: To investigate the relationship between fetuin A, metabolic parameters, and NAFLD in obese childre...

Background: Recent studies have suggested a role of IGF1 as a candidate prognostic marker for cardiometabolic complications of obesity.Objective: To investigate the relationship between IGF1 serum levels and both biochemical and metabolic parameters as well as body composition in a cohort of obese children.Methods: obese subjects (130F/157M), aged 11.2±2.7 years, were studied. Anthropometry, biochemical and metabolic parameter...

Background: Endoplasmic reticulum (ER) is the site where proteins are folded. Perturbation of ER homeostasis activates a set of ER-to-nucleus signaling reactions known as the unfolded protein response (UPR). Metabolic stress causes UPR activation which contributes to the development of insulin resistance and metabolic syndrome. As UPR can be activated by nutrient and oxygen starvation, we postulated that intrauterine growth restriction may trigger UPR signaling and thereby con...

Background: Pseudohypoaldosteronism (PHA) is a rare heterogeneous syndrome of mineralocorticoid resistance. PHA type 1 (PHA1) is characterized by neonatal salt loss, failure to thrive, dehydration and circulatory shock. It includes two forms: renal (autosomal dominant), due to mutations in mineralocorticoid receptor coding gene NR3C2, and systemic (autosomal recessive), due to mutations in subunit genes of the epithelial sodium channel (ENaC). ENaC is constituted of three subu...

Background: Wolfram syndrome (WS) is an autosomal recessive neurodegenerative disorder characterized by non-autoimmune diabetes mellitus and progressive optic atrophy. WS includes other possible disorders, such as diabetes insipidus, sensorineural deafness, genitourinary tract problems, neurological or psychiatric disorders and others.Case presentation: A 12-years-old boy presented with glicosuria and shortly developed insulin-dependent diabetes mellitus...

Hypothyroid patients post-thyroidectomy require 1.6-1.8 mg/kg/die of Levothyroxine (L-T4). A persistent TSH level above the upper limit despite a daily dose >1.9 mg/kg/die is defined as “refractory” hypothyroidism in adults. Malabsorption and “pseudo-malabsorption” need to be investigated in case of therapeutic failure. L-T4 absorption test (LT4AT) is useful in distinguishing these two conditions but it has only been described in adult age. We ...

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...

A 17-year-old girl comes to our attention for a second opinion due to reduced bone mineralization. She has a family history of osteogenesis imperfecta: her mother and younger sister have a COL1A1 mutation. The girl never had any fractures, but considering the familiarity it was carried out a DEXA, showing a Z-score of -1.9 SDS at the femoral level and -2 SDS at the lumbar level; no fractures visible in the spine X-ray. The genetic analysis of COL1A1 was carried out, which came...
