Background: The lack of agreement in the definition of vitamin D deficiency may be due to differences in the study populations or in the assays used to measure 25OHD.Objective and hypotheses: The aim of this study is to evaluate the relationship between 25OHD and PTH, and define the level of vitamin D deficiency in a paediatric population.Method: Retrospective medical record of children (age: 0.1–18years, n=193) who v...

Introduction: The start of GH (rhGH) treatment in children with GH deficiency (GHD) causes a significant increase in bone turnover and increases height velocity. The increase in IGF1 concentrations during rhGH treatment is a marker of the efficiency of treatment. A significant increase in bone turnover during rhGH treatment results in an increased demand for vitamin D. It is important to determine proper supplementation doses of vitamin D in patients during catch-up growth.</p...

Background: Vitamin D deficiency/insufficiency seems to occur frequently in children and teenagers but it is a matter of debate if limits (<20 ng/ml; <30 ng/ml) are correct. Besides its effect in bone metabolism Vit-D is also supposed to have a positive influence in diabetes mellitus 1 (DM1).Objective and hypotheses: To study 25OHD and iPTH values in a group of patients (pts) (n=57) with DM1 without Vit-D substitution (2011), with 1000 I...

Introduction: Several studies showing a high prevalence of vitamin D deficiency in pregnant women have been published in recent years. Vitamin D deficiency during pregnancy has been related to adverse events both in mother and child. Plasma 25-OH vitamin D (25(OH)D) levels in the newborn are dependent on maternal deposits and show a close correlation with maternal levels; thus, neonates of vitamin D-deficient mothers present a greater risk of hypocalcaemia, rickets and a highe...

Objective: It is known that vitamin D has differential roles in cell proliferation, differentiation, neurotransmission and neuroplasticity in nervous system and exerts neurotrophic and neuroprotective effects. In recent studies, it was shown that vitamin D could be protective against in age-related macular degeneration and optic neuritis related to demyelinating disorders. Here, we aimed to perform visual evoked potential (VEP) studies before treatment in patients with rickets...

Background: Vitamin D status in children with isolated GHD has been analyzed in few studies with controversial results. The aim of the study was to assess vitamin D status in children with idiopathic GHD in North and Central Greece.Materials and methods: 128 children (M/F: 76/61, mean age 9.5 (S.D.±3.5 years) with isolated GHD were compared with 65 controls (M/F: 46/3, mean age 9.3 (S.D.±3.2 years). Children were d...

Background: Animal studies suggest a role of vitamin D in fetal lung development although not studied in preterm animals.Objective and hypotheses: We tested the hypothesis that vitamin D depletion does not aggravate respiratory insufficiency in preterm rat offspring. Furthermore, the effects of vitamin D depletion on growth and lung surfactant were investigated.Method: Female Sprague-Dawley rats were randomly assigned low vitamin D...

Background: Treg cells are characterized by expression of Foxp3 molecule that serve as keys in the maintenance of peripheral tolerance and in controlling the immune response. The exact role of Treg cells in the pathogenesis of CAT has not been recognized yet.Objective and hypotheses: It is suggested that vitamin D is one of the factors that can regulate the function of Treg cells. In this study, the relationship between Treg cells (levels and expression)...

Objective: Vitamin D plays an important role in hyperlipidemia, cardiovascular disease risk, and glucose/insulin metabolism. The aim of this study is; to investigate the relationship between serum vitamin D levels and metabolic profiles of children with T1DM, atherogenic index, and cardiovascular disease risk.Materials and Methods: T1DM patients were included in the study retrospectively. Anthropometric and clinical measurements, biochem...

Background: 25-Hydroxyvitamin D (25(OH)D) deficiency is reported to be common in patients with rheumatoid arthritis and associated with disease activity, physical disability, and cardiometabolic intermediates; data in patients with juvenile idiopathic arthritis (JIA) are inconsistent.Objective and hypotheses: To assess serum 25(OH)D in children, adolescents, and young adults with JIA, and to identify the risk factors for vitamin D deficiency in JIA patie...
