View clinical trials related to Vitamin D Deficiency.
Filter by:This study is a randomised control trial (RCT) pilot study to determine the appropriate vitamin D dose for the main study. The pilot study includes three matched groups, which will form two vitamin D supplementation groups (at 25,000 IU and 50,000 IU every two months), and a third placebo supplementation group. The aim was to develop an appropriate supplementation regimen that was compatible with recruit training and maintained serum vitamin D (25OHD) status above 50 nmol/l during recruit training.
Determinate the level of vitamin D in blood, and evaluate the prevalence of deficit and insufficiency among patients with diagnosis of uterine fibroids
This study is determining the therapeutic effect of Vitamin D supplements to Pcos clomiphene resistant polycystic ovarian syndrome Women. Half of patients will receive Vitamin D with metformin while other half metformin only. Then both groups start clomiphene for 3 month
Assessing the combined effect of omega-3 fatty acid and vitamin D 3 on plasma osteocalcin levels
The combined effect of omega-3 fatty acid and vitamin D3 on lipid profile levels and oxidized low density lipoprotein: a randomized controlled trial in males and females with vitamin D deficiency
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).
Vitamin D supplementation in patients with uterine fibroids who present hypovitaminosis D to re-establish their normal serum values could stabilize the size of the uterine fibroids and thus prevent their growth or reduce their size thanks to the anti-proliferative action of Vitamin D on the myoma cells.
Primary Objectives: To evaluate the efficacy of metformin and Vitamin D supplementation on serum insulin and serum androgen levels (Total testosterone, Steroid Hormone Binding Globulin, Free Androgen Index) levels compared metformin alone in infertile Poly cystic ovarian females of reproductive age group. Secondary Objectives: To measure change in endometrial thickness/number of follicles and follicular size by day 12 trans-vaginal ultrasound in the intervention group i.e. combination of metformin and vitamin D supplementation
The aim of the study is to evaluate the relationship between the vitamin D replacement and pathological response in patients undergoing neoadjuvant therapy according to different molecular sub types. Because of no study evaluating pathological response to neoadjuvant therapy with vitamin D replacement in patients with breast cancer.
Asthma-COPD overlap (ACO) is a new entity in the world of respiratory ailments. The respiratory tract of these patients are continuously exposed to oxidants (due to cigarette smoking) causing oxidative stress. Antioxidant enzymes such as, superoxide dismutase (SOD) and catalase (CAT) neutralize these oxidants or free radicals and transform them into safer. Vitamin D is a natural antioxidant which has few evidence of increasing antioxidant enzyme level in COPD and asthma, but not in ACO patients. To evaluate the effects of vitamin D3 supplementation on antioxidant enzymes level in vitamin D3 deficient patients with stable ACO. The randomized controlled trial was conducted in Department of Physiology Bangabandhu Sheikh Mujib Medical University (BSMMU), Shahbag, Dhaka from March 2018 to February 2019. For this study, a total number of 40 vitamin D3 deficient (serum 25 hydroxycholecalceferol <30 ng/ml) male, stable (diagnosed patient, who was not experienced any acute exacerbation, hospitalization, urgent care visits or changes in routine medication within 4 weeks prior to study) patients with ACO of age ≥40 years was selected from the Out Patient Department (OPD) of the National Institute of Diseases of Chest and Hospital (NIDCH) and randomly grouped as A (control) and B (study). Then serum Superoxide dismutase and Catalase level of all the patients was assessed. Along with the standard pharmacological treatment of ACO (according to GOLD criteria), oral vitamin D3 (80,000 IU per week) will be supplied to the patients of the 'Study group' and placebo for 'Control group' for consecutive 26 weeks. At 26th week of follow up, all the study variables were examined. With this, all patients of both the groups were advised to continue ad lib (according to their own choice) diet. The results was expressed as mean±SD and the data was statistically analyzed by SPSS Version 16, using Independent sample 't' test (between two groups) and paired student's 't' test (between paired groups before and after intervention). In the interpretation of results, <0.05 level of probability (p) was accepted as significant.
