Background: There are limited data in paediatric population on the association between vitamin D deficiency/treatment and glucose/insulin metabolism.Objective and hypotheses: This study aimed to investigate the effect of vitamin D therapy on glucose homeostasis, insulin resistance and bone turnover, in children with vitamin D deficiency.Method: 22 children aged 3 months to 10 years (nine male) who were diagnosed with vitamin D defi...

Background: Steroids are found in human blood predominantly as sulfated steroids. Conjugation of steroids increases their solubility in blood, facilitating their physiological regulation and excretion. Chromatographic separation and quantification of an extensive number of sulfated steroids is challenging. For instance, androgen sulfates are structurally related and their signals are very similar in mass spectrometry.Objective and hypotheses: Some of the...

Background: Non-alcoholic fatty liver disease (NAFLD) is considered the hepatic manifestation of metabolic syndrome. Accelerated catch-up in weight during infancy in subjects born term has been associated with increased risk for NAFLD in adulthood, but this association has not been studied in subjects born preterm.Objective and hypotheses: To investigate the associations of birth weight, gain in weight for length and accelerated catch-up in weight in the...

Background: Recent guidelines recommend levothyroxine (LT4) monotherapy for all infants with congenital hypothyroidism (CH). However, up to one-third of patients have pituitary resistance to thyroid hormone and, to normalize their TSH, require supranormal circulating levels of T4. Liothyronine (T3) has been proposed as a supplemental therapy for such patients, but data demonstrating its use and efficacy are limited.Object...

Background: Several methods have been used to evaluate the risk of cardiovascular diseases in obese children. Both BMI and waist-to-hip ratio were suggested as risk factors. However, they did not prove to estimate the risk for cardiovascular events in adulthood. Recent studies suggest that the ratio of waist circumference to body height (WHtR) is a more reliable predictor for cardiovascular risk in 6-10-year old children (Kuba et al. 2013).Objec...

Background: Terminal deletions of chromosome 15q are associated with different degrees of pre- and post-natal growth failure, dysmorphic features, functional impairments and congenital anomalies. Although monosomies of 15q26 do not represent a classical contiguous gene syndrome, candidate genes for selected features have been identified. Short stature is referred to deletions of the IGF1-R gene, located on 15q26.3. We demonstrate evidence of phenotype comparable with 15q26 mon...

Background: Autoimmune thyroid disease (AITD) is the most common thyroid disorder in the paediatric age range. However, the development of thyroid dysfunction in biochemically euthyroid children with positive TPOAbs and associated risk factors is unclear.Objective and hypotheses: To evaluate the evolution of children with positive TPOAbs and normal thyroid function and identify predictive factors for the development of thyroid dysfunction.<p class="a...

Initially discovered in the 1970s, the C21 steroidal acids α-cortolic acid, β-cortolic acid, α-cortolonic acid and β-cortolonic acid present the terminal oxidative products of cortisol metabolism. Undergoing renal elimination, these cortoic acids have been assumed to represent up to 25% of total urinary cortisol metabolites. However, their analysis has been difficult, only few data has been published in adults, and this class of steroids has beco...

Case reports: Patient 1 was diagnosed with Williams Syndrome (WS) when she was 11 years-old. She presented typical facial features, mental retardation (IQ 34) and chronic constipation. Pregnancy and neonatal period were unremarkable. Her growth has always been satisfying. No cardiac defects were detected at echocardiogram. Cerebral MRI showed enlarged pituitary (height of 9 mm) in the contest of which a mass with suprasellar extension was detected. Thyroid and adrenal...

Introduction: The beginning of the COVID-19 pandemic encouraged a sedentary lifestyle and “covibesity” was reported. Concerns for consequences on anthropometric data, glycemic control, and lipid profile in subjects with type 1 diabetes (T1D) were raised.Objectives: Longitudinal and observational study aimed to investigate the 2-years effects of the COVID-19 pandemic on BMI, glycemic control, and lipid profile...
