Background: Many epidemiological studies have found high prevalence of vitamin D deficiency in children with type 1-diabetes mellitus (T1D). 1,25(OH)2D is a potent immune-modulator that also enhances the production and secretion of several hormones, including insulin. The association of low serum 1,25(OH)2D levels with high glucose level and diminished insulin sensitivity suggests that vitamin D may modulate insulin metabolism.Aim and objectives: To scre...

Background: Vitamin D plays a significant role in musculoskeletal health and various extraskeletal functions making the prevention and treatment of this vitamin (now considered as a hormone) of utmost importance. Literature on requirement/supplementation of vitamin D in asymptomatic children is scarce and this study was an attempt to see the effect of three different doses of cholecalciferol supplementation regimens in children with asymptomatic vitamin D deficiency.<p cla...

Background and aim: Childhood obesity is one of the most serious public health problem. Obesity-related complications such as hepatic steatosis or type 2 diabetes can now be monitored even during early childhood. The aim of the study was to examine the relationship between vitamin D levels and obesity with hepatosteatosis (HS) in children.Methods: A total of 128 children with obesity were included in this study. HS was diagnosed using ultrasonography. HS...

Background: Vitamin D Dependent Rickets Type IA(VDDR1a) is an autosomal recessive disorder characterized by defects in the biosynthesis of its active form 1,25 dihydroxyvitamin D due to the mutations in the CYP27B1 gene encoding for the enzyme 1α-hydroxylase.Objective and hypotheses: To evaluatethe clinical characteristics, molecular genetics aetiology and long-term outcome of a large nationwide cohort of VDDR-Ia f...

Backgrounds: The understanding of the efects and role of vitamin D and its analogues in the functioning of body tissues, systems and organs has improved substantially over the last decade. The potential extra-skeletal role of vitamin D has been a rich area of interest and research over the last decade. Vitamin D deficiency has been implicated in a variety of chronic diseases, including bone mineral disease, autoimmunity, cancer, and diabetes. Many epidemiologi...

Background: Nutritional rickets is a disorder of defective chondrocyte differentiation and mineralization of the growth plate and osteoid due to vitamin D deficiency with or without low calcium intake in growing children. Maternal Vitamin D deficiency and exclusive breastfeeding without supplementation are the most frequent causes of rickets in the infancy. Vitamin D deficiency is still a problem in Sri Lanka in spite of sun shine throughout the year. We present a case series ...

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...

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...

Background: Hypophosphatasia (HPP) is the rare inherited metabolic disease resulting from loss-of-function mutations in the tissue-nonspecific alkaline phosphatase (TNSALP) gene. Understanding of the clinical presentation is largely based on single case reports, which presents challenges for the recognition and diagnosis of HPP.Objective: To better understand disease presentation, we surveyed the literature to characterize clinical features and presentat...

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...
