Background: Over-dosing and under-dosing of vitamin D in children and young people appears to be common, based on our audit of current practice. The contribution of ethnicity, skin colour, and vitamin D binding protein (VDBP) genotype has not been fully explored during vitamin D treatment.Objective: To investigate how ethnicity/skin colour and genetic variation affect the response to 150 000 units of vitamin D administered to young adults of White Caucas...

Background: No large study comparing efficiency of prednisolone, alendronate and pamidronate has been conducted so far in children with hypercalcemia due to vitamin D intoxication.Objective and hypotheses: To perform a multicentre, retrospective study assessing clinical characteristics and treatment results.Method: A standard questionnaire was uploaded to an online national database system (www.favorsci.org) to collect data of chil...

Background & Purpose: Vitamin D is essential for bone and calcium metabolism, and a deficiency of this nutrient can lead to rickets and hypocalcemia. A 25 hydroxy-vitamin D (25OHD) value below 12 ng/mL (30 nmol/L) has been established by global consensus on the basis of several studies as constituting vitamin D deficiency. For example, (1) the incidence of nutritional rickets can increase at a 25OHD concentration of less than 12 ng/mL; (2) PTH increases wh...

Background: Vitamin D is a pleiotropic hormone the deficiency of which is related with extraskeletal manifestations such as insulin resistance and cardiovascular risk disease.Objective and hypotheses: To investigate the levels of VitaminD in a sample of children with obesity and to evaluate the relationship between carbohydrate metabolism and metabolic syndrome (MS).Method: In this prospective cross-sectional study, 189 children ag...

Background: Hypocalcemia is a common metabolic disorder in the neonatal period and may involve life-threatening situations. The aim is to analyze the main causes of hypocalcemia and its management.Objective and hypotheses: The aim is to analyze the main causes of hypocalcemia and its management.Method: Retrospective descriptive study by reviewing reports of 75 patients diagnosed of neonatal hypocalcemia (total Ca <7.6 mg/dl and...

Background: 1 000 million people worldwide presenting vitamin D deficiency in children prevalence of vitamin D deficiency in certain regions described up to 80%, especially at high latitudes (above 37). Has been postulated role of vitamin D in the immune system and in clinical variability DM1.Objective and hypotheses: To study the degree of deficit VITD in our population (Location: 42° 51’north latitude 2° 41’west longitude) with DM1 ...

Introduction: Vitamin D may be considered as a hormone of prohormone of pleiotropic effects. Seasonal variability of insolation affects its synthesis in humans. In our latitude, vitamin D deficiency is widespread. In 2018, updated recommendations for vitamin D supplementation were published in Poland by Rusi&nacute;ska et al. In 2020, SARS-CoV-2 pandemic lockdown was introduced, with suggestions of protective anti-viral vitamin D role.<p class="ab...

Background: There is high prevalence of Vitamin D deficiency (VDD) in Hashimoto’s thyroiditis (HT) as reported in literature. However, it is uncertain whether VDD is a cause or effect of HT. The effect L-thyroxine replacement on vitamin D levels in children with HT has not been studied.Objective and hypotheses: To study vitamin D level of newly diagnosed children with HT and to observe the change in vitamin D level after L-thyroxine therapy.<p c...

Aim: The aim of this study was to evaluate the effect of different doses of vitamin D supplementation on androgen levels in adolescent girls who were treated with metformin.Method: 45 adolescent girls diagnosed with hyperandrogenism were divided into the 3 different groups according to the treatment scheme. Patients treated with metformin (850 mg / day oral)(n = 15), metformin and vitamin D drops (2,000 IU / day)(<em...

Objectives: Vitamin D deficiency is an important health problem in pregnant women and their infants in sunny countries. The present study evaluated serum 25-hydroxyvitamin D3 (25(OH)D3) concentrations in pregnant women and in their newborns and determined the risk factors in LSES cities in Turkey.Methods: Ninety-seven pregnant women and their newborns were included in the study between December 2012 and February 2013. All of the pregnant women had irregu...
