Background: One strategy for improving population vitamin D status is consumption of fortified foods. However, the effects of dairy products fortified with different vitamin D isoforms on postprandial vitamin D status and metabolic outcomes have not been addressed.Objective: We investigated whether consumption of dairy drinks fortified with either 25-hydroxycholecalciferol [25(OH)D3] or cholecalciferol (vitamin D3) had differential effects on 24-h circulating plasma 25(OH)D3 concentration (a marker of vitamin D status) and cardiometabolic risk markers...

BACKGROUND: Vitamin D deficiency may increase esophageal cancer risk. Vitamin D affects genes regulating proliferation, apoptosis, and differentiation and induces the tumor suppressor 15-hydroxyprostaglandin dehydrogenase (PGDH) in other cancers. This nonrandomized interventional study assessed effects of vitamin D supplementation in Barrett's esophagus (BE). We hypothesized that vitamin D supplementation may have beneficial effects on gene expression including 15-PGDH in BE. METHODS: BE subjects with low grade or no dysplasia received vitamin D3 (cholecalciferol) 50,000 international units weekly plus a proton pump inhibitor for 12 weeks...

BACKGROUND: According to a small pilot study on palliative cancer patients at our ward, vitamin D supplementation had beneficial effects on pain (measured as opioid consumption), infections and quality of life (QoL) without having any significant side effects. OBJECTIVE: The primary objective of the 'Palliative-D' study is to test the hypothesis that vitamin D supplementation for 12 weeks reduces opioid consumption. The secondary objectives are to study if reduction of antibiotic consumption and fatigue as well as improvement in QoL assessments can be observed...

Vitamin D deficiency is prevalent in individuals with non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis. However, there is limited and inconsistent data on the effect of vitamin D supplementation on liver function. Hepatic enzymes have been used as surrogate markers for NAFLD and have been associated with metabolic syndrome. We examined the relationships between 25-hydroxyvitamin D (25(OH)D) and γ-glutamyl transferase (GGT), alanine aminotransferase (ALT), alkaline phosphatase (ALP) in 120 drug-naïve individuals with no history of liver disease...

Accumulating evidence indicates that the active form of vitamin D, 1,25(OH)2D3, can be considered as a neurosteroid. However, the cerebral expression of vitamin D-associated enzymes and receptors remains controversial. With the idea of carrying out a comparative study in mind, we compared the transcript expression of Cyp27a1, Cyp27b1, Cyp24a1, Vdr and Pdia3 in purified cultures of astrocytes, endothelial cells, microglia, neurons and oligodendrocytes. We observed that endothelial cells and neurons can possibly transform the inactive cholecalciferol into 25(OH)D3...

BACKGROUND AND AIMS: The relationship between vitamin D deficiency and type I DM is an ongoing area of interest. The study aims to identify the prevalence of vitamin D deficiency in children and adolescents with T1DM and to assess the impact of treatment of vitamin D deficiency on their glycaemic control. METHODS: Retrospective data was collected from 271 children and adolescents with T1DM. The vitamin D deficient (25(OH)D <30 nmol/L) and insufficient (25(OH)D 30-50 nmol/L) patients were treated with 6000 units of cholecalciferol and 400 units of cholecalciferol, once daily for 3 months respectively...

Background: To prevent preeclampsia, the WHO recommends antenatal calcium supplementation in populations with inadequate habitual intake. The WHO recommends 1500-2000 mg Ca/d with iron-folic acid (IFA) taken separately, a complex pill-taking regimen. Objective: The objective of this study was to test the hypothesis that simpler regimens with lower daily dosages would lead to higher adherence and similar supplement intake.Methods: In the Micronutrient Initiative Calcium Supplementation study, we compared the mean daily supplement intake associated with 2 dosing regimens with the use of a parallel, cluster-randomized noninferiority trial implemented in 16 primary health care facilities in rural Kenya...

Vitamin D deficiency is widely prevalent and often severe in children and adults with chronic kidney disease (CKD). Although native vitamin D {25-hydroxyvitamin D [25(OH)D]} is thought to have pleiotropic effects on many organ systems, its skeletal effects have been most widely studied. The 25(OH)D deficiency is causally linked with rickets and fractures in healthy children and those with CKD, contributing to the CKD-mineral and bone disorder (MBD) complex. There are few studies to provide evidence for vitamin D therapy or guidelines for its use in CKD...

BACKGROUND: Vitamin D has significant immunomodulatory effects on both adaptive and innate immune responses. Observational studies indicate that adults infected with HIV with low vitamin D status may be at increased risk of mortality, pulmonary tuberculosis, and HIV disease progression. Growing observational evidence also suggests that low vitamin D status in pregnancy may increase the risk of adverse birth and infant health outcomes. As a result, antiretroviral therapy (ART) adjunct vitamin D3 supplementation may improve the health of HIV-infected pregnant women and their children...

BACKGROUND: Some studies suggest an association between diabetic kidney disease (DKD) and vitamin D (VD), but there is no data about the effect of high dose of VD on DKD in type 1 diabetes mellitus (T1DM). Our pilot study aims to evaluate albuminuria reduction in patients with T1DM supplemented with high dose of VD. METHODS: 22 patients received doses of 4,000 and 10,000 IU/day of cholecalciferol for 12 weeks according to patient's previous VD levels. They were submitted to continuous glucose monitoring system, 24 hours ambulatory blood pressure monitoring and urine albumin-to-creatinine ratio before and after VD supplementation...

Deranged vitamin D metabolism represents an active trigger of secondary hyperparathyroidism (SHPT) in CKD. Correction of 25(OH)D deficiency by nutritional Vitamin D administration is suggested by KDIGO guidelines, to prevent and treat SHPT in CKD stage G3-G5 and G1T-G5T patients, although with a still inconsistent background. Nutritional vitamin D is available as cholecalciferol, ergocalciferol, or calcifediol. Superiority of calcifediol in increasing 25(OH)D levels has been suggested due to its better bioavailability...

BACKGROUND AND PURPOSE: Adults with compromised liver function are inherently deficient and especially vulnerable to the consequences of vitamin D deficiency. Consequences of vitamin D deficiency include liver disease progression, infection, and graft failure. A vitamin D supplementation protocol is proposed to systematically optimize serum vitamin D levels according to guidelines in both pre- and post-liver transplanted patients. METHODS: This quasiexperimental study included a sample of N = 45 post-liver transplanted patients taking daily cholecalciferol (vitamin D3) 2500 units for 12 weeks, with a pre- and post-lab measure of serum 25-hydroxyvitamin D levels at a large academic facility...

Recent evidence suggests that vitamin D deficiency may contribute to increased risk of depression. However, previous studies are limited by variability in participant characteristics including vitamin D deficiency status and presence of existing diseases, use of low doses of vitamin D supplementation for short durations, and use of co-interventions or psychotropic drugs. We examined whether 25-hydroxyvitamin D (25(OH)D) concentrations were associated with symptoms of depression, as well as whether vitamin D supplementation reduced symptoms of depression in overweight or obese and vitamin D-deficient, but otherwise healthy adults...

The term "vitamin D" refers to two chemical compounds - ergosterol, or vitamin D2, and cholecalciferol, or vitamin D3. Active vitamin D3 is correctly regarded as a neurohormone due to its pleiotropic biological activities. Although the relation between vitamin D and calcium-phosphorus metabolism has never been discussed, the knowledge on many other roles vitamin D plays is growing fast. Briefly, vitamin D immunomodulation includes attenuation and stimulation of Th1 and Th2 cell proliferation, respectively. Similarly, vitamin D can induce or inhibit the synthesis, secretion, and release of anti- inflammatory (IL-4 and IL-10) and pro-inflammatory (IL-1, TNF-α, IFN-γ) cytokines, respectively...
