Vitamin D may facilitate Clock/Bmal1-DNA interactions in a Vitamin D receptor-independent fashion

Nicolaides Nicolas , Papakonstantinou Eleni , Vlachakis Dimitrios , Chrousos George

Background: The Clock/Bmal1 transcription factor heterodimer regulates the circadian activities of many biological systems, including the hypothalamic-pituitary-adrenal (HPA) axis, by trans-activating or trans-repressing downstream target genes. 1,25 Dihydroxy Vitamin D (Vitamin D), a sterol hormone that is activated by exposure to sunlight, plays a fundamental role in maintaining calcium and phosphorus homeostasis. Recent evidence suggests that the nuclear vi...

Al Dubayee Mohammed , Albuhairan Fadia , Alalwan Ibrahim , Al Shahri Suleiman , Tamim Hani , Magzoub Mohieldin , Al Tamim Walid , Ahmed Nasreldin

Background: Vitamin D has a key physiological role in many metabolic process and neuromuscular activities. The peak bone mass accrual occurred during adolescence, where about 51% of bone mass is gained during puberty and about 37% of the bone mineral density (BMD) of adults is reached. Vitamin D deficiency has long-term negative implications including increased risk of osteomalacia and osteoporosis. Severe hypovitaminosis D appears to be most common in the Mid...

Stagi Stefano , Lapi Elisabetta , Scalini Perla , Greco Paolo Del , Ricci Franco , Marino Achille , de Martino Maurizio , Seminara Salvatore

Background: Down syndrome (DS) is the most common genetic (chromosomal) mental retardation syndrome. In these patients, several environmental and hormonal factors contribute to low bone mineral density (BMD), among these factors, vitamin D may play a significant role in the health of patients with DS. However, poor studies have evaluated 25-hydroxy cholecalciferol (25(OH)D) levels in DS.Objective and hypotheses: The purpose of this study was to assess se...

Thyroid Autoimmunity and Vitamin D Status in Euthyroid Girls with Hashimoto’s Thyroiditis

Isguven Sukriye Pinar , Aydin Dilek Bingol , Kilic Mukaddes

Background: Hashimoto thyroiditis (HT) is the most common autoimmune disorder. There are few studies that analysed the relationship between HT and serum vitamin D.Objective and hypotheses: It has been suggested that vitamin D acts as an immunomodulator in autoimmune diseases such as HT Therefore we planned to investigate vitamin D status in euthyroid girls with HT.Method: The study group consisted of 66 euthyroid pubertal girls rec...

The Relationships between Serum Vitamin D Level and Precocious Puberty in Korean Girls

Kim Se Young , Woo Yeoloon

Background: The recent articles showed a kind of associations of the serum vitamin D levels and chronic diseases, for example, autoimmune diseases, vascular disorders, as well as malignancies. Also vitamin D deficiency impacts normal growth and maximal bone mineral accretion in puberty. Of pediatric population in Korea, the prevalence of cases of vitamin D deficiency and precocious puberty were continuously increasing nowadays.Objective and hypotheses: W...

Infancy onset hypocalcemia due to maternal vitamin D deficiency

Pascu Bogdan , Ciobanu Carla

Hypocalcemia is a common metabolic problem and a recognized cause of seizures in neonates and infancy. Breastfed infants born to mothers who are vitamin D and or calcium deficient are at risk of developing vitamin D deficiency and hypocalcemia.Case report: We present two infants (two weeks old boy and a 9-month-old girl) with hypocalcemia caused by vitamin D deficiency admitted to our pediatric emergency department for seizures and tetan...
