Effect of vitamin D treatment on magnesium levels in chronic hemodialysis patient; a double blind controlled clinical trial
Abstract
Introduction: The homeostasis of magnesium (Mg) is impaired in chronic kidney disease (CKD) and it has been suggested that intestinal absorption of Mg may be affected by vitamin D status. 25-Hydroxy vitamin D or 25(OH)D deficiency is common in patients undergoing chronic hemodialysis; however the efficacy of nutritional vitamin D supplementation on Mg level in this population remains uncertain. Objectives: The aim of this study was to evaluate the effect of vitamin D treatment on Mg levels in chronic hemodialysis patients. Patients and Methods: This randomized clinical trial study was conducted on 69 chronic hemodialysis patients (mean age of 56.93 ±12.26 years) with serum 25-hydroxy vitamin D levels 0.05). Conclusion: Our study shows that oral vitamin D therapy can increase 25(OH)D levels in maintenance hemodialysis patients without significant alterations in serum calcium, phosphate, magnesium and parathyroid hormone during a 12-week period. Trial Registration: Registration of trial protocol has been approved by the Iranian registry of clinical trial (#IRCT20210314050698N1; https://en.irct.ir/trial/55159, local ethical code# IR.SKUMS.REC.1397.181).
How strong is the evidence?
