BACKGROUND & AIMS: Vitamin D (Vit D) deficiency in cystic fibrosis (CF) is partially secondary to exocrine pancreatic insufficiency. Our aim was to establish a Vit D3 supplementation protocol that will increase 25(OH)D to the recommended level (30 ng/mL). METHODS: Retrospective study of 200 patients (≥18 years) conducted from February 2007 to June 2014 at the CF clinic of the Centre Hospitalier de l'Université de Montréal. Vit D3 supplementation protocol was 1600 IU/day or 10,000 IU/week during the summer (May 1st to October 31st) and 3200 IU/day or 20,000 IU/week during the winter (November 1st to April 30th), in addition to the 1200 IU/day included in multivitamins...

INTRODUCTION: Americans are increasingly receiving vitamin D supplementation, often based on low-measured 25-hydroxy-vitamin D (25-OH-vit D). In sarcoidosis, there is often increased metabolism of 25-OH-vit D to 1,25-dihydroxy-vitamin D (1,25-OH-vit D), so 25-OH-vit D may remain low, despite high levels of 1,25-OH-vit D. In such cases, vitamin D supplementation may lead to hypercalcemia. METHODS: We randomly selected 196 patients with sarcoidosis who received at least 1 prescription of vitamin D between 2005 and 2011 and 196 control patients...

BACKGROUND: Vitamin D (Vit D) deficiency plays a central role in the pathogenesis of chronic kidney disease (CKD) complications, both skeletal and nonskeletal. The purpose of this study was to examine whether 25(OH)D levels and supplementation with oral cholecalciferol (Vitamin D3 (Vit D3)) are associated with morbidity and mortality among patients with significant CKD. METHODS: CKD patients attending the nephrology clinic at Shaare Zedek Medical Center between July 1, 2008 and January 31, 2012, tested at least twice for 25(OH)D levels, were enrolled...

25-hydroxy vitamin D [25(OH) vit D] deficiency is a serious public health problem, particularly in the Indian sub-continent. The objective of the present study was to study the prevalence of 25(OH) vit D in different age groups. The data of 25(OH) vit D assay of 26,346 ostensibly healthy individuals, enrolled under executive health checkup at Medanta The Medicity, Gurgaon, over a period of 3 years, were extracted from the hospital information system and reviewed extensively. 25(OH) vit D deficiency (VDD) was defined as 25(OH) vit D < 20 ng/ml, insufficiency (VDI) as 25(OH) vit D between 20 and 40 ng/ml and 25(OH) vit D sufficiency (VDS) as 25(OH) D > 40 ng/mL...

BACKGROUND: Hashimoto's thyroiditis (HT) is a common autoimmune disease. Vitamin D is an important regulator of immune system. It has been shown in several studies that vitamin D prevents the development of lots of autoimmune diseases. There are some studies that prove vitamin D receptor (VDR) gene polymorphism increases the risk of Hashimoto's thyroiditis. In this study, we aimed to investigate the association between HT and level of 25(OH)D3, IL-2, IL-4, IL-5, TNF-α and IFN-γ and VDR FokI and TaqI gene polymorphism...

UNLABELLED: Vitamin D deficiency and insufficiency are highly prevalent among adolescents in Hong Kong, which is a sub-tropical city with ample sunshine. Vitamin D level is significantly correlated with key bone density and bone quality parameters. Further interventional studies are warranted to define the role of vitamin D supplementation for improvement of bone health among adolescents. INTRODUCTION: The relationship between bone quality parameters and vitamin D (Vit-D) status remains undefined among adolescents...

The link between vitamin D and type 2 diabetes mellitus (T2DM) is intensively studied. This study aims to define the serum concentration of 25-hydroxyvitamin D (25-OH D) and to investigate the relationship between 25-OH D status, glycated hemoglobin (HbA1c) and body composition in postmenopausal women with T2DM and in non-diabetic controls. In this cross-sectional study, 75 women with T2DM and 32 control subjects were selected. Serum 25-OH D, intact parathyroid hormone (PTH), calcium, fasting glucose and HbA1c, were measured...

AIMS: To assess whether a single parental dose of 25-hydroxy vitamin D [25(OH)Vit D] could improve glucose control and inflammation in type 2 diabetic patients (T2D) with ischemic heart disease (IHD). METHODS: A randomized, placebo-controlled, double-blind trial was performed on 95 patients (47-placebo and 48-vitamin D groups). Participants were randomized using a randomization table to a single dose of either vitamin D (300,000 IU, IM) or a matching placebo. Fasting blood sugar (FBS), glycosylated hemoglobin (HbA1c), 25(OH)Vit D and high-sensitivity C-reactive protein (hs-CRP) were measured at baseline and at 8 weeks...

OBJECTIVE: Takayasu's arteritis (TAK) is a chronic, large-vessel vasculitis. Vitamin D, as a steroidal hormone, has recently been shown to have immunoregulatory and immunosuppressive effects. Low vitamin D levels are demonstrated in various autoimmune disorders. The aim of this study is to investigate vitamin D levels in patients with TAK. A comprehensive review of vitamin D levels in systemic vasculitides (SVs) is also performed. METHODS: The study included 36 patients with TAK, 28 patients with Behçet's disease (BD) as disease control and 30 sex-matched healthy controls...

Vitamin D [vit D; 1,25-(OH)2D] treatment improves survival and lung alveolar and vascular growth in an experimental model of bronchopulmonary dysplasia (BPD) after antenatal exposure to endotoxin (ETX). However, little is known about lung-specific 1,25-(OH)2D3 regulation during development, especially regarding maturational changes in lung-specific expression of the vitamin D receptor (VDR), 1α-hydroxylase (1α-OHase), and CYP24A1 during late gestation and the effects of antenatal ETX exposure on 1,25-(OH)2D3 metabolism in the lung...

BACKGROUND: Several studies suggest that Vitamin D (Vit-D3) supplementation reduces Chronic Urticaria (CU) symptoms. OBJECTIVES: Evaluation of serum 25-hydroxyvitamin-D (25 (OH)2D) level and assessment of therapeutic effect of VitD3in CU patients. METHODS: 192 subjects were stratified according to the baseline 25(OH)2D levels and subsequently randomized into three subgroups to receive Vit-D3 alone (VD) or antihistamine and systemic corticosteroid (H+S) or VitD3 with antihistamine and systemic corticosteroid (VD+H+S) for 6 weeks between July 2012 to Oct 2014...

UNLABELLED: Vitamin D and calcium are involved in a wide range of proliferation, apoptosis and cell signaling activities in the body. Suboptimal concentrations may lead to cancer development. The role of phosphate in cancer metabolism is particularly relevant in breast cancer while, magnesium deficiency favors DNA mutations leading to carcinogenesis. OBJECTIVES: To determine serum levels of vitamin D, calcium, phosphorus, magnesium, and parathormone in female breast cancer patients and to assess their association with some prognostic factors in breast cancer...

Suboptimal vitamin D (vit D) status (<32 ng/mL) is ubiquitous among African American children with type SS sickle cell disease (SCD-SS). The vit D supplemental dose to normalize vit D status is unknown. Five to 20-year-old African American children with (n=21) and without (n=23) SCD-SS were randomized to vit D3 supplementation (4000 or 7000 IU/d) and evaluated at 6 and 12 weeks for changes in vit D and SCD status. A dose was considered unsafe if serum calcium was elevated associated with elevated serum 25 hydroxyvitamin D (25(OH)D)...

BACKGROUND: As prevention of osteoporosis becomes more imperative with the global ageing of the population, establishing different measures to fight vitamin D deficiency will also become increasingly important. The aim of this study is to help assess the efficacy of vitamin D-fortified milk on circulating concentrations of 25(OH)D (as the primary outcome), a widely accepted indicator of vitamin D status, in Tehran students. Another objective of the protocol is to help assess the compliance with fortified dairy in students of different socioeconomic classes...
