NCT ID: NCT04323852 Completed - Inflammation Clinical Trials

Can Vitamin D Reduce Heart Muscle Damage After Bypass Surgery?

Start date: September 1, 2017
Phase: Phase 4
Study type: Interventional

Background and study aim: Heart diseases are among the most common causes of death worldwide. A large proportion of deaths are caused by heart attacks (myocardial infarction), where blood flow to the heart is reduced resulting in damage to the heart muscle. If the arteries supplying blood to the heart start to become blocked, Coronary Artery Bypass Grafting (CABG) surgery is a treatment to replace the blocked sections of artery can reduce angina (chest pain). However, CABG surgery has complications, including an increased risk of heart attack. Vitamin D deficiency is thought to be linked to poorer recovery from heart attack and CABG surgery. This study aims to investigate if vitamin D supplementation can reduce injury to the heart following CABG surgery. Who can participate? Adults with vitamin D deficiency undergoing CABG What does the study involve? Participants are randomly allocated to one of two groups. Those in the first group receive vitamin D at 3 doses per day for 3 days before surgery. The second group will receive a dummy pill (placebo). Both groups will have standard CABG surgery. What are the possible benefits and risks of participating? Those in the vitamin D group might benefit from its effects. Vitamin D has few side effects, especially when taken for only a few days. Where is the study run from? Shahid Modarres Hospital (Iran) When is the study starting and how long is it expected to run for? September 2017 to January 2019 Who is funding the study? Deputy of Research of Shahid Beheshti School of Medicine Who is the main contact? Dr Erfan Tasdighi erfan.tasdighi@gmail.com

NCT ID: NCT04307784 Completed - Clinical trials for Vitamin D Deficiency

The Effects of Vitamin D3 Alone and in a Combination With Omega-3 on the Association of C-peptide With Glycemic Control

Start date: March 10, 2020
Phase: N/A
Study type: Interventional

The Effects of Vitamin D3 alone and in a combination with omega-3 on the association of C-peptide with glycemic control

NCT ID: NCT04292873 Completed - Critical Illness Clinical Trials

Effects of Enteral Supplement Vitamin D Incritically Ill Patients

Start date: March 16, 2020
Phase: N/A
Study type: Interventional

At present, there is no clinical reference data on how much the concentration of calcifediol in the blood increases after supplementing with vitamin D for Taiwanese ICU patients. This study aims to investigate the effects of enteral supplementation of vitamin D in critically ill patients with vitamin D deficiency. The results of the study are expected to provide clinical reference data to intensivists to select adequate dosage of vitamin D supplementation for their patients with vitamin D deficiency. This is a multi-center, randomized clinical trial. ICU patients will receive vitamin D level examination. If the subject's blood calcifediol concentration is less than 20 ng / mL, the subject will be included in this clinical trial. Patients who are suitable to enteral supplement of vitamin D will be randomly divided to group Control (no vitamin D supplement) and group Vitamin D (enteral supplement of 569,600 IU vitamin D). The vitamin D level will be measures at specific time points.

NCT ID: NCT04291833 Completed - Knee Osteoarthritis Clinical Trials

Prospective, Assessment of Vitamin D and Calcium Supplementation, Improvement of Nutritional Status and Preoperative Rehabilitation in Patients Before Knee Arthroplasty.

Start date: January 1, 2015
Phase: N/A
Study type: Interventional

Prospective randomized study of 150 patients qualified for knee arthroplasty between 2015 and 2017. Patients were randomized into 3 groups receiving vitamin D and calcium supplementation, increased protein supply and preoperative rehabilitation, respectively. Following factors were analyzed: changes in vitamin D3, calcium, total protein, albumin and CRP levels during preparation for surgery, nutritional status on the Subjective Global Assessment (SGA) scale, osteoporosis risk assessment according to the Osteoporosis Risk SCORE, level of pain felt on the scale VAS and the number of analgesics used, the result of the Duke Activity Status Index, the result of the following scales: Cardiac Risk Index for Orthopedic Surgery (Lee), Knee injury and Osteoarthritis Outcome Score (KOOS), Fear Avoidance Beliefs Questionnaire (FABQ) about Physical Activity, The Quality of Life Scale (QOLS). Additionally, the occurrence of perioperative complications was analyzed (e.g. venous thrombosis and pulmonary embolism, wound or joint infection, excessive bleeding, loosening of the implant, bone fracture or fracture, pain).

NCT ID: NCT04276649 Completed - Ulcerative Colitis Clinical Trials

A Retrospective Analysis: the Influence of Caltrate Supplement on the Effect of Mesalazine in Ulcerative Colitis

Start date: January 1, 2015
Phase:
Study type: Observational

Aims:Retrospectively observe the effects of Caltrate supplementation on the clinical effect of mesalazine in patients with ulcerative colitis. Design: From January 2015 to December 2020, through retrieving the clinical database of the Second Affiliated Hospital of Wenzhou Medical University, patients with active UC who accepted mesalazine treatment were enrolled. According to whether Caltrate was supplemented at the same time, the patients were divided into supplementary group and non-supplementary group. The modified Mayo score and several laboratory indicators were compared between the two groups.

NCT ID: NCT04209231 Completed - Clinical trials for Vitamin D Deficiency

Effect of Vitamin D on Periodontal Disease

Start date: November 2015
Phase:
Study type: Observational

Background. Vitamin D has both direct effects on bone metabolism and an antimicrobial effect on periodontopathogens. It also inhibits inflammatory mediators that contribute to periodontal destruction. The purpose of this study was to evaluate the association between serum 1.25-hydroxyvitamin D (1.25(OH)2D3) and 25(OH)D levels and periodontal inflammation. Methods. This study included 28 subjects with chronic gingivitis, 29 subjects with chronic periodontitis and 25 periodontally healthy subjects. Blood samples were collected from the participants to determine serum levels of 25(OH)D, 1.25(OH)2D3, tumour necrosis factor α (TNF-α), C-reactive protein (CRP) and interleukin 6 (IL-6). Clinical parameters were recorded. Results were statistically analysed with a Shapiro-Wilk's test, Mann-Whitney U test, Kruskal-Wallis H test, Wilcoxon test and post-hoc multiple comparison test.

NCT ID: NCT04207294 Completed - Clinical trials for Vitamin D Deficiency

Vitamin D Enriched Meat Project (Acute Study)

Start date: January 16, 2020
Phase: N/A
Study type: Interventional

The importance of achieving an adequate vitamin D status is widely recognised, with public health and research communities heightening their interest over recent years. Whilst vitamin D can be synthesised following skin exposure to UV light, due to public health concerns regarding sun safety, and modern indoor lifestyles, it has become evident that endogenous synthesis may not be an effective means of maintaining an adequate vitamin D status across the year. Given the marked variation in seasonally-induced cutaneous synthesis, habitually low dietary vitamin D intakes of 2-4µg/day typically reported within nationally represented population surveys, and the generally low uptake of supplementation at the population level, it is warranted to identify alternative food-based strategies to yield greater adherence to the 10µg DRV, particularly during winter months where sunlight exposure is negligible. Commodity-based biofortification may provide an innovative and viable additional food-based approach to suboptimal vitamin D status, in combination with safe sun exposure, inclusion of natural and fortified dietary sources and/or supplementation. Meat naturally contains vitamin D3 and 25(OH)D3, yet by manipulating feeding regimes and/ or housing environments, it is possible to improve the concentration of both metabolites in animal products. Eggs, beef and pork provide viable opportunities for the enhancement of vitamin D3 and 25(OH)D3 which contribute to an increase in total vitamin D activity (vitamin D3 + [25(OH)D3 x 5]), and therefore would be expected to positively impact vitamin D status. Albeit whilst much biofortification research has been established, less is known regarding its effectiveness at raising circulating serum 25(OH)D concentrations amongst apparently healthy adults, with the exception of some plant-based foods. Therefore, an opportunity exists to understand the bioavailability of vitamin D-enriched pork and vitamin D-enriched chicken to increase 25(OH)D concentration.
