Background: Recent studies have found a widespread deficiency of vitamin D during pregnancy. Its significance is still not fully understood, although low Vit-D levels have been associated to increased risk for conditions such as preeclampsia, bacterial vaginosis, neonatal sepsis, and early respiratory infections in the child. Supplementation to the pregnant mother is still a matter of debate, therefore it is important to understand better the causes, risk factors, and possible...

Background: Hereditary 1,25-dihydroxyvitamin D resistant rickets (HVDRR) caused by vitamin D defective receptor.Objective and hypotheses: We performed VDR gene analysis four patients with alopecia, skeletal dysplasia, and hypocalcaemia.Method: Genomic DNA extracted from peripheric blood. Whole gene sequence analysis was performed.Results: We found homozigot p.Q152* (c.454G>T) mutation three patients. Two ...

Introduction: Vitamin D (VitD) is a prohormone that is synthesized in the skin after sun exposure. Mandatory lockdown during the COVID-19 Pandemic may have altered the sun exposure time of children.Aim: to evaluate vitD levels in a sample of children and adolescents, and compare between pre-pandemic and pandemic periods.Methoths Children and adolescents, from a Portuguese tertiary ...

Introduction: Breast milk is a perfect food, but it can be deficient in vitamin D. In the Danish study, vitamin D was correlated in mothers, breast milk and not in breast milk and infants. We investigated the correlation between mother, breast milk, and infants vitamin D levels in Japan.Materials and Methods: This study included 84 pairs of mothers and 2-week-old infants born at the Iizuka Hospital and Vitamin D includin...

Background: The prevalence of childhood obesity has increased dramatically in the last decades and accounts for a significant increase in morbidity and mortality in adulthood.Objective and hypotheses: To determine the prevalence of 25-hydroxyvitamin D insufficiency and deficiency in overweight and obese children and adolescents.Method: 350 (n=350) children and adolescents (153 males (M), 197 females (F)) were recruited to ...

Background: Hereditary Vitamin D-Resistant Rickets (HVDRR) is a rare autosomal recessive disorder caused by mutations in the vitamin D receptor (VDR) resulting in end organ resistant to 1a,25-dihydroxyvitamin D, [1,25(OH)2D]. Majority of HVDRR has Elevated 1, 25(OH)2D which is a hallmark for diagnosis of this disease. High doses of vitamin D, oral calcium and most importantly IV calcium infusion are the mode of therapy in HVDRR.A...

Introduction: Vitamin D-dependent rickets type I (OMIM # 264700) is a rare autosomical recessive disorder that affects vitamin-D metabolism characterized by severe hypocalcaemia with moderate hypophosphatemia. The most common form is type IA, caused by the mutation of gene coding for 1-alpha-hydroxylase (CYP27B1OMIM * 609506. 12q14) that converts the 25-OH-vitaminD in 1,25-OH-vitaminD.Case report: A 2.3 years female with...

Several observational studies have reported vitamin D deficiency (VDD) in children with type 1 diabetes mellitus (T1DM). The investigation of VDD in children with new onset T1DM in China is lacking. The current study aimed to assess vitamin D status and examine the factors that influence VDD in children with new onset T1DM in Henan Province, China. Children with new onset T1DM (n=280) and healthy controls (n=710) were enrolled in Henan Province. Demographic a...

Background: Accumulating evidence suggests that decreased 25-hydroxyvitamin [25(OH)D] concentrations are associated with components of the metabolic syndrome.Objective: The aim of our study was to investigate the effect of vitamin D supplementation on metabolic syndrome parameters in obese children and adolescents.Patients and methods: Two hundred thirty two (n=232) obese children and adolescents aged [mean ±S....

Background: Vitamin D deficiency has been associated with left ventricular geometry and hypertrophy and larger end-systolic diameters and worse left ventricular function in animals and humans.Objective and hypotheses: The aim of this study was to investigate any possible association between vitamin D levels and geometry of left ventricle (LV) in youngsters with type 1 diabetes mellitus (T1DM).Method: 58 youngsters with T1DM with me...
