NCT ID: NCT05657678 Recruiting - Clinical trials for Vitamin D3 Deficiency

Vitamin D3 Supplementation in Critically Ill Patients Undergoing CRRT

NephroD
Start date: December 20, 2022
Phase: Phase 4
Study type: Interventional

Patients hospitalized in intensive care units (ICU) are particularly susceptible to vitamin D3 deficiencies. This can be due to the severity of their underlying disease, the type of treatment they are on, malnutrition before and inadequate nutrition during the hospitalisation preceding ICU admission, as well as advanced age. It has also been established that plasma levels of 25(OH)D3 tend to systematically decrease during ICU treatment. Therapeutic interventions administered in ICU settings such as fluid resuscitation or extracorporeal therapies can cause additional vitamin D3 deficiencies. The incidence of deficiency in critically ill patients can reach up to 90%, and even 30% of ICU patients can have undetectable plasma levels. It is impossible to replenish vitamin D3 levels in critically ill patients with traditional enteral and parenteral nutrition treatment regimens, because nutritional products contain too little of the vitamin. Vitamin D3 deficiency in critically ill patients has been associated with acute kidney injury, acute respiratory failure, sepsis, septic shock and increased all-cause ICU mortality. Despite that, assessment of plasma 25(OH)D3 levels is not a routine practice in ICUs. In view of the prevalence of vitamin D3 deficiencies in ICU patients, rapid replenishment of this deficiency with an increased supplementation dose should be considered as a potential means to improve prognosis in this patient population. The current standard therapy is the administration of 500,000 IU of vitamin D3 via the enteral route in ICU patients with severe deficiency (recommended by ESPEN). The NephroD study is meant to help answer the question whether increasing the standard ICU supplementation dose of vitamin D3 by 50% will ensure a more effective replenishment of this vitamin in critically ill patients undergoing CRRT.

NCT ID: NCT05340985 Not yet recruiting - Clinical trials for Multiple Sclerosis, Relapsing-Remitting

Investigating the Effects of Hydroxyvitamin D3 on Multiple Sclerosis

Start date: July 2022
Phase: Phase 4
Study type: Interventional

Investigating the effects of hydroxyvitamin D3 on clinical, radiologic and immunomodulatory markers in MS patients: A randomized, clinical trial- a pilot study

NCT ID: NCT05329428 Active, not recruiting - Clinical trials for Vitamin D Deficiency

PREDIN: Pregnancy and Vitamin D Intervention Study

PREDIN
Start date: April 14, 2022
Phase: N/A
Study type: Interventional

Vitamin D deficiency is common among certain risk groups in Sweden, and occurs approximately in every tenth pregnant woman.The aim of the randomized double-blind controlled trial Pregnancy vitamin D intervention (PREDIN) is to investigate the dose of vitamin D supplementation required in achieving vitamin D sufficiency (25OHD ≥50 nmol/l) in pregnant women at risk of vitamin D deficiency. In addition, the investigators aim to examine if the overall vitamin D status and vitamin D intake have increased since the expanded vitamin D fortification program was initiated in year 2020.

NCT ID: NCT04841213 Completed - Tooth Loss Clinical Trials

Dental Implants Rehabilitation in Patients With Vitamin D3 Imbalance

Start date: April 10, 2021
Phase: N/A
Study type: Interventional

Interventional retrospective prospective randomized clinical trial (RCT) in parallel groups. The sample size is 384 patients with loss of teeth and vitamin D imbalance. All patients will undergo or underwent dental implantation after additional investigations which reveal vitamin D imbalance (<30 ng/ml or <75 nmol/l). The 1 group will include 192 patients who will be or were operated on with dental implants after stabilization of vitamin D level with a help of an endocrinologist. The 2 group will include 192 patients who will be or were operated on during the treatment of vitamin D imbalance prescribed by the endocrinologist. The possible difference between groups can be considered the change of dental implants survival time and bone resorption level depending on the level of vitamin D and treatment time by the endocrinologist.

NCT ID: NCT04404842 Recruiting - Clinical trials for Vitamin D Deficiency

Development of a Screening Tool for the Risk of Vitamin D Deficiency

EvidenceQ
Start date: January 14, 2020
Phase:
Study type: Observational

Since vitamin D deficiency is a condition that affects a high percentage of individuals of all ages and given the attention on the possible role of the deficiency of this vitamin in the development of various chronic diseases, including cardiovascular and metabolic disease (obesity, insulin resistance, hypertension, diabetes) and the correlation with mortality from major cardiovascular events (heart failure, myocardial infarction, sudden cardiac death, stroke, atrial fibrillation and peripheral vascular disease), it is clear that in clinical practice it is necessary to provide screening tools characterized by a simple use, high efficacy and a low economic impact, useful to detect a possible deficiency state that has a significant impact on general health and therefore provide targeted interventions for diagnosis and supplementation when and if necessary. Therefore, the objective of this study project is part of the broader context of supporting, with reproducible and shared scientific data, operational protocols useful for the clinician to identify subjects potentially at risk of vitamin D deficiency as well as directing to the diagnostic and more effective therapeutic. Surveillance of vitamin D status should be a high priority in which easy-to-use and interpreted tools, such as the questionnaire developed for this study, could respond to the needs of early identification of subjects potentially at risk of hypovitaminosis D, thus supporting the work of the clinician.

NCT ID: NCT04342078 Active, not recruiting - Lung Diseases Clinical Trials

Vitamin D and Health Outcomes in Preterm Born Population

ViDePrePop
Start date: September 1, 2018
Phase:
Study type: Observational

Improved survival of very preterm newborn population during the last decades has challenged us neonatologists to study and improve nutritional practices including vitamin D (VitD) supplementation. However, long term outcome in this aspect has not been researched in well documented preterm populations. As VitD has receptors in almost all human cells it modulates growth of many organs. Therefore I start to assess VitD supplementation practices and later health outcome (bones, teeth, muscles, heart, lungs) in two preterm population cohorts cared in Oulu University Hospital at the age of 5 years and 24 years (born 2014-2017 and 1994-1997).

NCT ID: NCT04225819 Suspended - Ulcerative Colitis Clinical Trials

Adjunctive Treatment With Vitamin D3 in Patients With Active IBD

ACTIVATED
Start date: October 1, 2020
Phase: N/A
Study type: Interventional

Inflammatory bowel disease ((IBD), which includes Crohn's disease (CD) and ulcerative colitis (UC)), is a chronic, immune-mediated disease characterized by recurrent episodes of relapse. The incidence of IBD is increasing worldwide and poses as a burden that reduces quality of life and has a significant impact on health care resources. The advent of monoclonal antibodies to tumor necrosis factor-α (anti-TNF) has revolutionized treatment of IBD, improving rates of remission and reducing hospitalizations and surgeries. Nevertheless, many patients do not adequately respond to these therapies or lose response over time. Thus, there is an important need for novel immunomodulating agents to improve our ability to achieve remission. Besides its traditional role in bone homeostasis, several studies have recognized the important role Vitamin D plays in modulating the immune response, cancer, and cardiovascular disease. Specifically, Vitamin D may mediate immunity by modulating autophagy in leukocytes and regulating the gut microbiome. Thus, Vitamin D may play an important role in IBD. Furthermore, evidence suggests that the effect of vitamin D may be mediated through the TNF-α pathway, suggesting a synergy with anti-TNF therapy. This is a randomized, double blind, placebo-controlled trial to study the effect of Vitamin D3 as an adjunct therapy for patients with active CD, UC, or IBD unspecified who are undergoing anti-TNF induction therapy.
