Cystic fibrosis (CF) is the most common genetic respiratory disease in the west, which is due to a malfunction in protein of cystic fibrosis transmembrane regulator (CFTR). Since some studies showed the effect of vitamin D supplementation and increment in 25OHD serum level in these patients, this study aimed to conduct a review in this scope. For reaching the available studies, a search was con...
Introduction and purpose: Vitamin D supplementation is associated with inducing physiological skeletal muscle responses and improving performance. The aim of this study was to determine the effect of 8 weeks of vitamin D supplementation on biomotor components and liver inflammatory factors in female futsal player's deaf national team. Materials and Methods: For this purpose,16 female futsal pla...
Background The discovery of vitamin D is one of medicine's great achievements. Despite all the positive evidence emerging about the beneficial effect of vitamin D, we still find many are vitamin D deficient. The purposes of this study were to examine the association between serum 25-hydroxyvitamin D (25(OH)D) and glycosylated hemoglobin (HbA1c) levels, to test the hypothesis that lower 25(OH)D ...
Obesity is often associated with vitamin D deficiency and secondary hyperparathyroidism. Vitamin D supplementation typically leads to the reductions in serum parathyroid hormone (PTH) levels, as shown in normal weight individuals. Meanwhile, the dose of vitamin D supplementation for the suppression of PTH may differ in overweight and obese adults. We conducted a systematic review and meta-analy...
Multiple sclerosis (MS) patients were randomized, in a double blind design, and placed into either a vitamin D supplemented group or a placebo control group. As expected, serum 25-hydroxyvitamin D levels increased significantly following 6 month vitamin D supplementation (17+/-6 ng/ml at baseline to 28+/-8 ng/ml at 6 months). Vitamin D supplementation also significantly increased serum transfor...
Background & Aims: Vitamin D plays several important roles in human body. Studies showed that low serum 25(OH) D results in hyperglycemia, hypertension and cardiovascular disease. The objective of current study was to examine the effect of 3-month supplementation with 1000IU vitamin D on blood pressure in prediabetic adults. Materials & Methods: In a 3 month randomized clinical tria...
Background Vitamin D deficiency is a prevalent and important global health problem. Because of its role in growth and development, vitamin D status is likely to be particularly important in adolescent girls. Here, we explored the effects of high-dose vitamin D supplementation on cardio-metabolic risk factors. Methods We have examined the effects of vitamin D supplementation on cardio-metabolic ...
Background Vitamin D deficiency is common in women with PCOS. Vitamin D is thought to influence the development of PCOS through gene transcription, and hormonal modulation influences insulin metabolism and fertility regulation. Therefore, the aim of this review article is to study the effects of vitamin D supplementation in reproductive function of PCOS women. MaterialsAndMethods This review ar...
Vitamin D is a fat-soluble steroid hormone that activates vitamin D receptor to regulate multiple downstream signaling pathways and transcription of various target genes. There is an association between vitamin D deficiency and increased risk for cardiovascular disease. However, most of the studies are observational and associative in nature with limited data on clinical application. Thus, ther...
Background: This study was designed to assess the effects of calcium and vitamin D supplementation on the metabolic status of pregnant women with gestational diabetes mellitus (GDM). Methods: This randomized placebo-controlled trial was performed at maternity clinics affiliated to Kashan University of Medical Sciences, Kashan, Iran. Participants were 56 women with GDM at 24–28 weeks ge...
