Background: Neonatal vitamin D deficiency (VDD) can result in symptomatic hypocalcemia, seizures and cardiomyopathy and has been associated with reduced bone mineralization in childhood, but is potentially preventable with antenatal cholecalciferol supplementation. Single nucleotide polymorphisms (SNP) in the vitamin D metabolism pathway are associated with serum 25-hydroxyvitamin D [25(OH)D] in adulthood. We assessed whether maternal and/or offspring SNPs in ...

Background: Obesity is usually correlated with a higher prevalence of 25OH vitamin D (25OHD) deficiency. This might be due to either volumetric dilution of vitamin D in the large fat mass or its increased uptake by adipose tissue. To our knowledge, a systematic study on 25OHD levels in Prader-Willi syndrome (PWS), a genetic disorder associated with severe obesity, is not available.Objective and hypotheses: To analyze the 25OHD values in a population of p...

Newer studies have indicated that vitamin D has more widespread effects than the classical effects on bone and calcium-phosphate homeostasis. The presence of the vitamin D receptor (VDR) in the testis and male reproductive tract indicates a role for vitamin D in male reproduction. Indeed, vitamin D deficiency and global knock out models of VDR or CYP27B1 in rodents have shown that vitamin D and calcium are important regulators of male reproductive function. Several groups have...

Introduction: Vitamin D deficiency in children is still a global health problem. Measuring free 25-hydroxyvitamin D concentrations could provide a better estimate of the vitamin D status than total 25-hydroxyvitamin D (25(OH)D) levels.Objective: To assess the relationship between measured free vitamin D (m-f25(OH)D) and calculated free 25(OH)D (c-f25(OH)D), total 25(OH)D, intact parathyroid hormone (iPTH) and other markers of phosphocalcic metabolism. Es...

Background: Vitamin D deficiency has a high prevalence in children. It is produced by the skin from exposure to sunlight but its synthesis is influenced by many external and internal factors.Objective and hypotheses: The study aims to evaluate vitamin D in children with different pathology and highlights the influencing factors of it.Method: We evaluate 25-hydroxyvitamin D levels in 84 patients, sex ratio 1.15:1, aged between 3 mon...

Background: Glucose metabolism effects of vitamin D deficiency are debated. GH therapy is associated with increased insulin values and decreased insulin sensitivity.Objective and hypotheses: To investigate vitamin D status in short children treated with GH- to investigate if the known effects of GH therapy on glucose metabolism are modulated by vitamin D supplementation.Method: 41 children treated with GH for short stature where ev...

Introduction: Lysosomal Acid Lipase Deficiency (LAL-D) is a rare and systemic condition, secondary to LIPA gene mutations, responsible for lysosomal accumulation of cholesterol esters and triglycerides. Clinical manifestations are heterogeneous in terms of age of onset, severity and biochemical and radiological findings. Dyslipidemia, hepatomegaly and hepatosteatosis with hypertransaminasemia are the most common features. There is significant evidence of incre...

Background: Transverse Myelitis (TM) is an auto-immune syndrome with neural injury to the spinal cord. The TM may be first clinical manifestation of Multiple Sclerosis (MS). It is known that Turner’s Syndrome (TS) is associated to the presence of autoimmune diseases.Case Report: A 15-year old female, began with manifestations of loss of strength on the lower limbs evolving rapidly with sensorial loss, tetraparesis and hemodynamic instability, requir...

Background: In both asthma and vitamin D deficiency is common. The results from studies examining the relationship between them is contradictory.Objective and hypotheses: The aim of this study was to investigate the relationship vitamin D levels and clinical parameters of asthma in children.Method: One hundred twenty children with asthma, followed up in Pediatric Allergy and Immunology Department were included. Seventy-four childre...

Background: An optimal vitamin D status is important for the growth and development of bones in children and adolescents. The prevalence of vitamin D deficiency is still high, even in low-latitude and industrialized countries, and vitamin D deficiency in childhood is reemerging as major public health issue.Objectives: To determine the frequencies of 25-hydroxyvitamin D (25(OH)D) deficiency and insufficiency in children and adolescents.<p class="abste...
