Background and Aim: Vitamin D plays a crucial role in skeletal and extra-skeletal physiology. It is essential for growth, development and health. It works as a paracrine and autocrine signaling molecule that affects nearly all systems in the body. Vitamin D deficiency (VDD) is prevalent in many countries in all age groups, and may be overlooked due to the variable clinical presentations according to age. This study was conducted to assess vitamin D status amon...

Background: Cushing's syndrome (CS) is very rare in children and the most common cause is the high doses of glucocorticoids (GC) administered. It is well known that application of potent GCs cause iatrogenic CS (ICS) due to suppressing hypothalamo-hypophyseal-adrenal (HPA) axis and later even adrenal insufficiency (AI). Other side effects of GCs are also seen in these patients.Objective: The aim of this study is to r...

Aım: İn this prospective planned study, it was aimed to study relationship between vitamin D level and vitamin D receptor gene polimorphism in patients with type l DM aged 0–18 years old.Methods and materials: We enrolled total 165 children in which 101 new and old diagnosed to WHO criterias TIDM patients from 0–18 years old and 64 chıldren as control group who were matched with gender and age. İn all cases serum Ca, P, PT...

Objective: To evaluate the level of 25 (OH) D – vitamin in obese adolescents living in the South of Russia.Materials and method: We examined 20 obese adolescents with varying degrees of severity, aged 15.5±0.3 years, ten girls and boys. The comparison group consisted of ten healthy adolescents matched for age and sex. Obesity was calculated by BMI. Level of 25-(OH) D – vitamin was studied in the laboratory by ELISA (nmol/l). Furthermore, t...

Background: Vitamin-D-dependent rickets 1A (VDDR-1A) is a extremely rare, autosomic recessive genetic form of rickets caused by a defect in vitamin D 1α-hydroxylase enzyme which leads to low levels of 1,25-(OH) vitamin D.Herein, we report two Moroccan sisters R.E. and N.E. (respectively 3 and 15 months old), born from consanguineous parents, who presented with psychomotor retardation and failure to thrive.<str...

Background: Studies examining vitamin D levels in association with childhood obesity usually do not concurrently measure levels of vitamin D-binding protein and do not calculate the unbound, bioavailable vitamin D, that is considered the fraction of 25-hydroxyvitamin D able to exert biological activity.Objective and hypotheses: To evaluate in a group of children for the most part obese i) the concentrations of both total 25-hydroxyvitamin D and of the bi...

Introduction and Aim: FGF-23 is a hormone that works by inhibiting phosphorus reabsorption in kidneys, and systematic regulation of phosphate homeostasis by FGF23 depends on the activity of the membrane protein Klotho. It affects the active vitamin level according to the bioactive free vitamin hypothesis, which binds DVBP to vitamin D and prolongs its half-life. In this study, it was aimed to investigate 1.25 (OH) Vitamin D, Vitamin D Binding Protein, FGF-23 a...

Background: Vitamin D deficiency is now a critical issue due to its high prevalence and side effects.Objective and hypotheses:: We assessed the serum vitamin D status of obese and non-obese children and comparing their therapeutic response to identical oral vitamin D consumption in Iran.Method: This study was performed in children aged 2–14 years at Children Medical Center of Tehran in Iran. At first, the serum 25-hydroxy vita...

Background: Vitamin D deficiency may be associated with increased risk of metabolic syndrome.Objective and hypotheses: We aimed to assess the relation between 25-hydroxyvitamin D (25(OH) D) with the different metabolic syndrome components in overweight and obese subjects.Method: Ninety eight subjects (≥85th percentile for age and sex) recruited from the Diabetes, Endocrine & Metabolic Paediatrics Unit (DEMPU), Cairo Unive...

Background: 25-OH vitamin D levels in newborns depend directly on their mother’s status. In a previous study, 25-OH vitamin D levels were determined in cord blood in a cohort of women after winter months, showing deficient values in 94% of population (mean 25-OH vitamin D value 10.4±6.1 ng/ml). Correlation between low 25-OH vitamin D levels and low sun exposure, dark skin phototype and Indo-Pakistani ethnicity were observed.Objective and hypoth...
