NCT ID: NCT05957692 Completed - Hypovitaminosis D Clinical Trials

Vitamin D and Adipose Tissue: a Complex Relationship

ADIPOVITAD
Start date: January 1, 2020
Phase:
Study type: Observational

The goal of this observational study is to verify the role of adipose tissue in determining the vitamin D serum level after monthly oral administration in subjects with vitamin D deficiency. The main questions it aims to answer are: - Adipose tissue represents a storage environment for vitamin D or it's an environment where vitamin D is sequestered and no longer released - On the other hands, it's possible to verify whether the adipose tissue carries out a bi-modal activity towards vitamin D - If adipose tissue exerts a bi-modal effect, it is possible to identify a specific threshold between the two effects Participants will undergo anthropometric measurements (height, weight, waist/hip ratio waist circumference) at baseline and after 6 months of intake of cholecalciferol 50,000 IU/month

NCT ID: NCT05922696 Completed - Anemia Clinical Trials

Start date: May 15, 2022
Phase: Phase 2/Phase 3
Study type: Interventional

This is prospective single-blind randomized study, in Ain Shams University hospital) in Egypt, to assess the impact of Cholecalciferol on Anemia status in regular hemodialysis outpatients

NCT ID: NCT05916053 Completed - Clinical trials for Vitamin D Deficiency

Supplementation and Depressive Symptomatology Incidence Among Saudi Arabian Adults

Start date: September 1, 2021
Phase: N/A
Study type: Interventional

The goal of this randomized controlled trial is to explore the relationship between Vitamin D supplementation and depressive symptomatology in Saudi Arabian Population. The main questions it aims to answer are: - Is Vitamin D deficiency associated with an increased prevalence of depressive symptomatology among Saudi Arabian Population? - Is Vitamin D Supplementation for a period of 3-month at 50,000 International Units might be associated with an improved depressive status? All the participants were clients who attended the clinic to help with weight management - who were doing regular medical check-ups - at Al Themal Medical Center which is located in Abha, Saudi Arabia. Participants were requested to do a general blood test to check for any vitamins and minerals deficiencies as part of the routine clinical procedure. This procedure did not incur any additional costs on the behalf of the participants. The participants who were identified to have any deficiencies were recommended to take supplements, also as part of the routine clinical procedure. Therefore, participants identified to be deficient or insufficient Vitamin D levels were screened and recruited to participate in the current study. Participants were randomly assigned to either an interventional (vitamin D) or placebo group (control). The interventional group received vitamin D supplementation of 50.000International Units/week for 3 months and the placebo group received dietary advice and education on food sources of vitamin D for the same period. Both Groups received a weight gain or a weight loss diet as per their case. At the three-months follow-up, the participants were readministered the face-to-face questionnaire and their blood levels for vitamin D were also checked. Thus, this study would add value to the actions taken to treat vitamin D deficiency in Saudi Arabian adults. This might also assist in approaching new recommendations related to preventing or treating depression via vitamin D supplementation.

NCT ID: NCT05848349 Completed - Clinical trials for Vitamin D Deficiency

Vitamin D Status Among Infertile Women in Sweden

Start date: September 1, 2020
Phase:
Study type: Observational

The goal of this prospective cohort study is to learn about the overall and seasonal prevalence of vitamin D insufficiency and its determinants in a population of women with infertility who will go through in vitro fertilization in Sweden. The main questions it aims to answer are: - What is the prevalence of vitamin D insufficiency? - What are the determinants of this insufficiency? Participants will be asked to complete a questionnaire validated for dietary assessment of vitamin D intake and sun exposure habits and they will leave a blood sample for measurement of 25(OH)D concentration. Researchers will compare the in vitro fertilization outcomes between women with vitamin D insufficiency and sufficiency to see if there is any difference.

NCT ID: NCT05806723 Completed - Clinical trials for Diabetes Mellitus, Type 2

Effects of High Intensity Statin Therapy on Steroid Hormones and Vitamin D in Type 2 Diabetic Men

Start date: March 1, 2021
Phase: Phase 4
Study type: Interventional

The aim of the study was to assess the effect of high intensity statin therapy on testicular and adrenal steroids and vitamin D levels in type 2 diabetes males.It is a prospective study, conducted between march 2021 and July 2022, including 60 men with type 2 diabetes, aged 40 - 65 years, statin-free, and in whom a treatment with high intensity statin was indicated. The patients had two visits, before and six months after a daily intake of 40 mg of atorvastatin. During each visit, they underwent a clinical examination including the Androgen Deficiency in the Aging Male (ADAM) questionnaire and a fasting blood sample was collected for biological and hormonal measurements.

NCT ID: NCT05706259 Completed - Clinical trials for Vitamin D Deficiency

Start date: January 11, 2023
Phase: N/A
Study type: Interventional

This is an open-labelled, randomized controlled clinical trial aimed to compare the pharmacokinetics of an orodispersible vs a soft gelatin vitamin supplementation in vitamin D deficient healthy adults.

NCT ID: NCT05661006 Completed - Clinical trials for Vitamin d Deficiency

ETOL-Elderly Study of the Efficiency of the Innovative Food Supplement in Elderly Adults

ETOL-Elderly
Start date: February 20, 2020
Phase: N/A
Study type: Interventional

The aim of this pilot study is to conduct a study on geriatric population in Slovenia (non-users of dietary supplements/medicines with vitamine D, vitamin B12 and protein) and assess deficiency of selected nutrients, and to investigate the efficiency of the innovative food supplement prototype in improving nutritional status of elderly adults.

NCT ID: NCT05649462 Completed - Ulcerative Colitis Clinical Trials

Effect of Vitamin D Supplementation on Vedolizumab Response in Patients With Ulcerative Colitis

Start date: January 1, 2020
Phase:
Study type: Observational

It is uncertain whether vitD3 supplementation is beneficial for the remission of ulcerative colitis (UC). The effects of vitD3 supplements on the efficacy of vidrecizumab in Chinese UC patients were retrospectively analyzed. Methods: Patients with moderate to severe UC were recorded. These patients were initially treated with VDZ. VitD3 supplementation was defined as 400IU/d vitD3 supplementation during the first infusion of VDZ and continued throughout the follow-up period. Disease activity was assessed using the modified Mayo score.

NCT ID: NCT05630339 Completed - Clinical trials for Vitamin D Deficiency

Magnesium and Vitamin D Combination for Post-COVID Syndrome

Start date: January 30, 2022
Phase: N/A
Study type: Interventional

The goal of this double-blind randomized controlled clinical trial is to determine the efficacy of the administration of magnesium chloride + vitamin D as an adjuvant in the treatment of post-Coronavirus Disease (COVID) syndrome. The participants will be integrated: a) Intervention group that will receive 1 g of magnesium chloride (equivalent to 300 mg of elemental magnesium) + 4000 IU of vitamin D once a day, for four months. b) Control group that will receive inert placebo for four months. The outcome variable will be the improvement of the post-COVID syndrome. At the beginning and end of the study, blood samples will be taken to determine serum levels of vitamin D, total magnesium, ionic magnesium, calcium, fasting glucose and lipid profile. The evaluation of the efficacy and safety of the proposed intervention will be carried out by establishing the differences between the intervention and control groups.
