Background: There is no agreement on the optimal treatment of children with vitamin D deficiency or insufficiency without obvious signs of rickets.Objective and hypotheses: To compare the efficacy and side effects of two different stoss therapy regimens (10 000 IU/kg and 300 000 IU vitamin D3) in children with vitamin D deficiency or insufficiency without rickets.Method: A total of ...

Background: Simple obese is a worldwide public health problem. Recent studies suggested a possible relationship between obese and vitamin D deficiency.Objective and hypotheses: To discuss the relationship between 25-Hdroxyvitamin D with glucose and lipid metabolism of simple obese in Chinese children.Method: 65 children with obeses (35 mild-to-moderate, 50 severe) and sixty-two children with normal weight were enrolled in this tria...

Background: There is increasing evidence of vitamin D deficiency world-wide resulting in nutritional rickets. With increasing use of fast foods and reducing appropriate physical activity. Our world is encountered with the problem of obesity which increases the risk of 25-hyroxy vitamin D deficiency.Objective and hypotheses: The aim of this study was to determine the status of serum 25(OH)D level in children 2–14 years old who visited in a pediatric ...

Objective: To present a patient with hypercalcemia caused by a parathyroid adenoma and a deletion of the VDR gene.Case clinic: The case is that of a 13-year-old male who presented with hypercalcemia, muscle weakness, nephrocalcinosis, two pathological fractures and a family history of nephrocalcinosis. Physical examination was unremarkable, except the presence of a fracture of the left femur. Laboratory findings: Total s...

Background: Vitamin D deficiency is prevalent in infants and children in underdeveloped countries. Secondary myelofibrosis has been reported as a complication of severe rickets and in these children anemia, myeloid metaplasia and bone aplasia strongly suggested myelofibrosis.Case report: We report a case of myelofibrosis in two years old boy with severe vitamin D deficiency rickets and hepatosplenomegaly. He presented wi...

Objective: Most recent evidence from conducted in human and animal studies suggests that vitamin D has a potential role in the physiology of reproductive function in both genders. We investigate the role of vitamin D in male and female gonadal function at mini-puberty period with particular emphasis on production of sex steroids and gonadal peptide hormones. Additionaly, this study evaluated serum levels of luteinizing hormone (LH), follicle-stimulating hormone (FSH), estradio...

Background: Few studies have assessed 25-hydroxy vitamin D [25(OH)D] status among Italian children.Objective and hypotheses: To assess 25(OH)D in children and adolescents living in Tuscany, Italy, identifing risk factors for vitamin D deficiency in different age groups.Method: We evaluated 446 children children and adolescents (2.4–17.8 years), from Mugello (latitude 44° N), and we determined 25(OH)D, calcium, alkaline ph...

Objective: To compare the serum 25-hydroxy Vitamin D [25(OH)D] concentrations in children and adolescents with obesity with and without hepatosteatosis, and investigate the relationship between serum 25(OH)D concentrations and severity of hepatosteatosis. We also aimed to assess the effect of vitamin D treatment after 6 months on hepatosteatosis and liver biochemistry.Methods: One hundred thirty-three obese patients with...

Objective: To evaluate bone mineral density (BMD) and its relationship with vitamin D in children with obesity.Methods: We examined 110 children in the University Hospital (Minsk) from 2015 to 2018 yrs. Their anthropometric parameters (height, weight, body mass index (BMI)) were determined. Body composition with evaluating of mineral component were made by dual energy X-ray absorptiometry with the calculation of feet, hands, spine, ribs, hips BMD (g/cm<s...

Background: Vitamin D dependent rickets type II (VDDR II) is a rare autosomal recessive disorder, inherited due to mutation on vitamin D receptor (VDR) leading to end organ unresponsiveness to vitamin D. It is characterized by an early onset refractory rickets, hypocalcaemia, hypophosphatemia, growth retardation, hyperparathyroidism and elevated circulating levels of 1,25-dihydroxyvitamin D3 which is the hallmark of the disease.Objective and hypotheses: ...
