Effect of Oral Magnesium on Vascular Calcification in Chronic Kidney Disease


Brief description of study

Randomized placebo-controlled double-blinded interventional trial to investigate the effect of oral magnesium supplementation on vascular calcification in subjects with chronic kidney disease. We hypothesize that oral magnesium supplementation will reduce vascular calcification in subjects with chronic kidney disease while not decreasing bone mineral density.

Detailed Study Description

Chronic kidney disease (CKD) is associated with increase cardiovascular morbidity and mortality independent of traditional cardiovascular risk factors due to increased vascular calcification. Epidemiological and experimental data suggest that hypermagnesemia and magnesium supplementation reduce vascular calcification in CKD by increasing calcium/phosphate solubility in serum, by inhibiting calcium influx into vascular smooth muscle cells (VSMC), by inhibiting intracellular pro-calcification enzymes in VSMC and by increasing activity of intracellular anti-calcification enzymes in VSMC. However, there have been concerns that any anti-calcification effect of magnesium might also reduce bone mineral density, in which case there might be an increased risk of bone fractures associated with magnesium supplementation in CKD. We wish to conduct a randomized placebo-controlled double-blinded interventional trial to examine whether oral magnesium supplementation will reduce vascular calcification in subjects with CKD while not decreasing bone mineral density.
