Background: Sun exposure may be limited in Arctic populations and Greenland Inuit have adapted to the Arctic environment. The influence of chronic low vitamin D level on PTH to uphold a normal serum calcium remains to be elucidated.Objective: To describe the association between PTH and factors known to influence PTH-, including vitamin D (25OHD) and calcium, in Arctic populations.Methods: Inuit and non-Inuit in the capital city Nuu...

Introduction: The effect of vitamin D± calcium supplementation in children has traditionally been assessed using growth parameters, biochemical markers and radiographs.Objectives: To evaluate the utility of Bone Health Index (BHI), obtained using automated hand radiogrammetry, in assessing treatment effect in children participating in a vitamin D supplementation trial.Methods: In this double-blind placebo-controlled trial, Afg...

Recent studies suggest the link between low vitamin D levels and the prevalence of cardiovascular disease, diabetes, hypertension and a number of different types of cancer. Nowadays, vitamin D deficiency is recognized as a pandemic health problem and pediatric cancer patients may be even at higher risk than the healthy children. Children suffered from malignancy are especially exposed to its deficiency, because of the potential impact of the disease and its treatment. However,...

Introduction: Serum 25(OH)D concentrations for optimal bone metabolism in children is unknown. Only few data exist describing the effects of increasing serum 25(OH)D on bone metabolism markers.Aim: The aim of the study was to explore the association between serum 25(OH)D and bone metabolism markers in children.Patients and methods: Serum levels of bone formation (OC, P1NP) and bone resorption (CTx) markers (Cobas e411, Roche Diagno...

Objective: The objective of this observational cross-sectional study is to identify the prevalence of vitamin D deficiency in healthy women in Greece, as reflected by the levels of 25-hydroxyvitamin D (25(OH)D), since recent data indicate that vitamin D deficiency can be common in countries previously considered as low risk (e.g. Mediterranean countries).Materials and methods: A population of 840 community dwelling women was recruited at the health promo...

Introduction: Vitamin D deficiency is common in patients with rheumatoid arthritis and may be related to disease activity.The aim of the study was to evaluate the association between 25(OH)D level and disease activity in patients with rheumatoid arthritis.Materials and methods: The study included 61 patients with rheumatoid arthritis, 73.8% were women, 70.4 patients were younger 60 years old. Subjects suffering from liver and kidne...

Background and objectives: Vitamin D deficiency causes calcium-depleted bone, which further weakens the bones and increases the risk of fractures. Also, It is known as related to obstetrics problem like gestational diabetes, infections, preeclampsia and incidence of caesarean section as well as glucose metabolism, immune system, cardiovascular diseases and cancer.Recently, the relationship between preterm birth and vitamin D deficiency becomes the main i...

A osteoporotic fracture has become a global health issue that causes tremendous impact on mortality as well as heavy socioeconomic burden. Previous studies suggested that vitamin D may prevent fractures by improving muscle mass as well as via increasing bone density directly. The purpose of the study is to determine that the influence of vitamin D on bone mineral density depends on its effects on muscle mass.We analyzed the data from Korean National Heal...

Objectives: The correlation between vitamin D and GH–IGF1 axis is documented. Growing children, need extra Vit-D because it is required for growth. Severe deficiency in Vit-D generates poor growth. Height is usually more affected. Growth hormone (GH) deficiency in children causes severe growth retardation, Vit-D deficiency, and osteopenia. The aim of this presentation was: 1. To evaluate the Vit-D blood level to children in substitution treatment with rhGH. 2. To see if t...

Aim: Determining level of vitamin D and other conditions in children with osteoporosis.Methodology: Bibliography review in a worldwide basis about the issue and what we have observed.Outcome: We studied the level of 25OHD3 in all patients with osteoporosis and osteopenia. 25OHD3 95% deficit was found in these patients when reduced bone mass occurs. There are several disorders for hypocalcemia. Intestinal malabsorption syndromes, re...
