Active clinical trials for "Vitamin D Deficiency"

In Egypt, according to UNICEF 2018, Acute Respiratory Tract Infection (ARTIs)was estimated to account for 11% and 19% of the under-five and post-neonatal mortalities respectively. Despite the well-recognized role of vitamin D in metabolism and homeostasis in the general population, there is now growing interest in its probable association with pneumonia. Globally, about 30% to 90% of Under-5 children experience vitamin D deficiency. This could vary among children, according to the socioeconomic, environmental and behavioral circumstances. Studies evaluating the association of 1,25 (OH)2D deficiency and the severity of respiratory tract infection, are rare and showed controversial findings. However, an Indian systematic review polled the results of 12 studies, with 2279 participants, highlighted the significant correlation between vitamin D deficiency and incidence and severity of ALRIs. A prospective cohort study conducted in Yemen examined the ability of deficient levels of vit.D to predict the outcomes of severe pneumonia. The study documented the significant association between vitamin D deficiency with neutropenia and hypoxia in patients with severe pneumonia, thus predicting the poor prognosis. In Egypt 2010, a case-control study conducted on children aged 2 to 5 years to examine the impact of vitamin D deficiency on the susceptibility of pneumonia. The study illustrated that Vitamin D deficiency is associated with a higher incidence and more severe pneumonia. Recent studies advocated providing children(particularly suffering from pneumonia) with adequate amounts of vitamin D supplements. Nevertheless, few studies have been conducted to evaluate the impact of vitamin D supplementation on the outcome of pneumonic infants. Thus, we urge to conduct a randomized controlled trial (RCT) in Abou ElReesh tertiary Pediatric hospital, to evaluate the effects of vitamin D3 supplementation to children with pneumonia. We postulated that supplementation of 100 000 IU of vitamin D3 (Cholecalciferol) will reduce the duration of illness in those children and improve their outcome.

Aims:Prospectively observe the effects of Caltrate supplementation on the chronic course of Crohn's disease patients, analyze whether the effect of Caltrate on CD patients is affected by factors such as disease site, disease activity, treatment, etc.Provide a certain theoretical basis for "precision treatment" for CD patients in the future. Design：It is a prospective cohort study. Investigators include a total of 60 participants with CD according to the inclusion and exclusion criteria, and divide them into two groups to assess their initial disease activity and detect related indicators. At the same time，Investigators detect the Vitamin D Gene gene polymorphisms in all participants.One group is given Caltrate 0.6g per day orally, and the control group do not intervene. After 12 months, re-evaluate the disease activity and retest the relevant indicators, and use statistical methods to analyze whether Caltrate supplementation treatment can increase the serum 25 (OH) D level of CD participants, improve the condition of CD participants,relationship with Vitamin D Gene Polymorphism，and analyze the effect of Caltrate on participants with CD is affected by factors such as disease site, disease activity, and treatment.

This study will be an assessor-blind, randomized controlled trial in patients with CSU. The investigators will compared Vit D level in patients with Chronic spontaneous urticaria (CSU) and controls. Enrolled CSU patients with Vit D level <30ng/ml will be then randomized into three intervention arms in the ratio of 1:1:1. Patients belonging to intervention group A will be treated with low dose Vit D (2000 IU/day) for 12 weeks according to the Indian council of medical research (ICMR) guidelines. Intervention group B patients will be treated with high dose Vit D (60,000 IU/week) for 12 weeks and group C will not be given any Vit D supplements. All patients will be evaluated after 12 weeks. The urticaria activity score over 4 days (UAS4) will be used to assess the disease severity using the number of wheals and pruritus intensity based on the EAACI/GA2LEN/EDF guidelines. The patient's disease severity levels will be graded as mild (0-8), moderate (9-16), and severe (17-24).

This is a pilot randomized controlled trial of lower vs. higher dose vitamin D supplementation in D-deficient asthmatic children, to determine necessary sample sizes for outcome measures in a larger multisite study, and to examine possible relationships and effect sizes between various biological markers that may be important to the pathophysiology of childhood asthma. Aims of the study are to: Evaluate effect sizes for relationships between serum 25OH-vitD and omega-fatty acid (FA) biomarkers, before and after supplementation with lower or higher dose vitamin D, on immune function, and asthma severity. Characterize changes in innate and adaptive immune function and inflammatory responses in asthmatic D-deficient youth at baseline and after vitD supplements, by dietary O6:O3FA status and vitD dose.

Abstract: The main objective of the proposed study is to examine the Safety and Efficacy Evaluation of the Dose Regimen of Vitamin D 50,000 IU (Biodal) tablet supplementation in the treatment of population with vitamin D deficiency. A randomized, double-blind placebo, Parallel design comparing vitamin D with Placebo will be conducted on 60 Healthy males and females with vitamin D deficiency, age from 18 to 49 years who attend the rehabilitation clinics at Jordan University Hospital .Participants who met the inclusion criteria will be asked to sign an informed witnessed consent form. Results obtained are expected to assess the safety and efficacy of the dose regimen used in this study as per Biodal SmPC. This study will also contribute to the global body of knowledge in this field. The major findings generated from this study could open certain avenues for further research through the association of the status of vitamin D in serum .

The purpose of this study is to determine the effect of normalization of vitamin D levels on bone density, immune and adipocyte function in HIV1-seropositive patients.

The purpose of this study is to determine whether a daily supplement of vitamin D, taking before and during pregnancy, effects child birth weight, pre- and postpartum complication and bone mineral density during lactation.

The purpose of this study is to determine the effects of vitamin D supplementation in patients with heart failure and vitamin D deficiency on ventricular function, inflammatory cytokines, brain natriuretic peptide, lipid profile, glucose, serum insulin, serum parathyroid hormone and calcium.

Vitamins A, D, and E play important roles in humans, such as vision function, immune function, bone metabolism, cell growth and differentiation and oxidation resistance. Deficiencies in these vitamins will result in a high prevalence of cardiovascular disease, infection, bone diseases, etc. Preterm infants, especially very low birth weight infants, are at risk of vitamin deficiency. Intravenous perfusion is the most common and widely used method to supply vitamins for the specific population in early life. However, the current dose of vitamin supplied by intravenous perfusion whether can meet the need of growth and development is not sure and the appropriate dose for preterm infants is still uncertain. The purpose of this study is to investigate whether current dose of fat-soluble vitamin supplementation is enough for very low birth weight infants, the safety of high dose of fat-soluble vitamin supplementation, and compare the differences of prevalence of common complications, such as bronchopulmonary dysplasia, patent ductus arteriosus, sepsis, anemia, and neural development between these two groups.
