Dogan Murat , Aydin Ilyas , Kaba Sultan , Bala Keziban Asli , Gulpinar Ozlem

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...

Lykkedegn Sine , Sorensen Grith Lykke , Beck-Nielsen Signe Sparre , Pilecki Bartosz , Duelund Lars , Marcussen Niels , Christesen Henrik Thybo

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...

Siklar Zeynep , Karatas Deniz , Dogu Figen , Kocaay Pinar , Hacihamdioglu Bulent , Ikinciogullari Aydan , Berberoglu Merih

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)...

Zenger Gulberil , Selver Eklioglu Beray , Emre Atabek Mehmet , Kurban Sevil ,

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...

Stagi Stefano , Capirchio Laura , Marino Achille , Bertini Federico , Seminara Salvatore , de Martino Maurizio , Falcini Fernanda

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...

Comparison of efficacy and safety of oral cholecalciferol administration at 4-week intervals and daily administration to correct vitamin D deficiency in adolescents

Choi Jinjoo , Choe Yunsoo , Yang Seung

Objectives: Vitamin D deficiency is prevalent in pediatric population. Since low compliance may inhibit appropriate vitamin D supplementation in daily dosing regimen, intermittent high dose administration may be considered. We aimed to evaluate the efficacy and safety of monthly administration of oral cholecalciferol compared with daily dosing regimen in adolescents with vitamin D deficiency.Methods: This retrospective s...

Central Hypothyroidism and Biallelic Defect Near the D/ERY Motif of the TRHR Gene

Garcia Marta , de Buitrago Jesus Gonzalez , Pardo Leonardo , Hinkle Patricia M. , Moreno Jose C.

Background: The TRH receptor (TRHR) is a G-protein coupled receptor activated by hypothalamic TRH. In thyrotropes, TRH-TRHR signalling controls synthesis, secretion and bioactivity of TSH. Human TRHR defects are extremely rare, and only three cases are known with central hypothyroidism and short stature as variable presenting feature.Objective and hypotheses: Phenotypical characterization of a family with suspected central hypothyroidism and inv...

Vitamin D Levels in Children, Adolescents, and Young Adults with Juvenile onset Systemic Lupus Erythematosus: a Cross-sectional Study

Stagi Stefano , Capirchio Laura , Bertini Federico , Menchini Camilla , Scalini Perla , Seminara Salvatore , de Martino Maurizio , Falcini Fernanda

Background: Hypovitaminosis D is common in the general population. Although many studies on 25-hydroxyvitamin D (25(OH)D) are available on systemic lupus erythematosus (SLE), little data is present in juvenile onset SLE (JSLE) patients.Objective and hypotheses: This study aimed to assess serum 25(OH)D levels in JSLE patients and to identify risk factors for vitamin D deficiency in this population.Method: Forty-five consecutive Cauc...

Vitamin D Status in Romanian Children 0–18 Years – Should we be More Careful Regarding Supplementation?

Chirita-Emandi Adela , Puiu Maria

Background: In Romania (latitude 48°15’N to 43°40’N), vitamin D supplementation is a common practice mostly in 0–2 year old infants. No published information is available regarding vitamin D status in Romanian children.Objective and hypotheses: We aimed to evaluate the seasonal and age variation of vitamin D status in a large Romanian pediatric patient population.Method: 1 395 individuals, 0–18years, f...
