The Optimal Dosage of Vitamin D Supplement for Vitamin D deficiency in Korean Children and Adolescents

Yang Seung , Hee Yi Kyung , Kim Eun Young , Hwang Il Tae

Purpose: Vitamin D deficiency (VDD) is very common nowadays in children as well as in adults, probably due to decreased exposure to sunlight. In Korea, the prevalence of VDD was 47% in teenage boys and 65% in teenage girls. However, the optimal dosage regimen for correcting deficiency is unknown. We investigate the change of serum 25(OH) vitamin D concentration according to the treatment dosage and duration in VDD.Methods...

Response to Vitamin D Replacement is Determined by Body Surface Area in Children with Vitamin D Deficiency

Chung In Hyuk , Kang Yu Sun , Yoo Eun-Gyong

Background: The serum 25-hydroxyvitamin D (25OHD) levels are known to be lower in obese children, probably due to sequestration of vitamin D in the adipose tissue. However, there is no consensus on the dose adjustment for vitamin D supplementation in obese children with vitamin D deficiency (VDD).Aims: To compare the response to vitamin D replacement in normal weight vs overweight children with VDD, and to investigate the determinant for increment of 25O...

Karem Mona , Gamal Heiba Ebtehal , Kamel Noha , Gad Suzan

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...

The effects of vitamin D supplementation on infant bone mass and body composition

Weiler Hope A.

Vitamin D supplementation is recommended for breastfed infants as primary prevention of vitamin D deficiency and nutritional rickets. Globally, the most commonly recommended dosage of vitamin D is 400 IU/day for healthy breastfed infants. Whether there are benefits of higher dosages of vitamin D to infant bone mass and body composition has been investigated. The objective of this presentation is to review the evidence from randomized controlled trials conducted in healthy term...

Matveeva Mariia , Samoylova Julia

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...

A Case of Vitamin D Deficient Rickets Showing Resistance to the Treatment of Active Vitamin D: Severe Calcium Deficiency Cause Vitamin D Resistance

Tanaka Hiroyuki , Hasegawa Kosei , Takatsuka Moe , Okahara Chika , Noguchi Yoshie , Takata Tsutomu , Ogura Kazuo

Case presentation: A 2-year-boy was referred tour hospital for the rickets. He was the first son between non-consanguineous parents and fed with breast milk. But after weaning, he was avoided from taking egg, dairy products including cow’s milk. He was also suffered from developmental delay and had strong food preference. He could take only two kinds of foods, steamed rice and soy bean product, tofu. X-ray findings showed typical rachitic change on long bone metaphysis. L...

A Novel Pathogenic Mutation of Vitamin-D-Dependent Rickets

Norberto Pin Jacopo , Cossettini Micol , Fabris Francesco , Martelossi Stefano

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...

Grandone Anna , Del Giudice Emanuele Miraglia , Cirillo Grazia , Di Sessa Anna , Umano Giuseppina , Marzuillo Pierluigi , Capristo Carlo , Perrone Laura

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...
