The Effect of Increasing Dialysate Magnesium on Calcification Propensity in Subjects on Haemodialysis

2016-12-01 16:08:22 | BioPortfolio


The purpose of this trial is to examine the effect of increasing dialyse magnesium on serum calcification propensity in subjects with end-stage renal disease treated with haemodialysis.


Patients with end-stage renal disease (ESRD) have a 20-fold increased risk of cardiovascular mortality compared to the general population. Arterial stiffness, likely due to vascular calcification (VC), has been shown to predict cardiovascular mortality in ESRD. Serum calcification propensity (T50) is a novel biomarker, which is believed to reflect the propensity toward ectopic calcification (e.g. VC). Increasing serum magnesium (sMg) should increase T50, which might in turn reduce the formation of VC in patients with ESRD. A cheap and easy way of achieving this would be to increase the concentration of Mg in the dialysate (dMg) of patients with ESRD treated with haemodialysis (HD).

The investigators wish to conduct a randomised controlled double-blind clinical trial to examine whether increasing dMg will improve T50 in subjects with ESRD treated with HD.

Medical and Biotech [MESH] Definitions

Magnesium chloride. An inorganic compound consisting of one magnesium and two chloride ions. The compound is used in medicine as a source of magnesium ions, which are essential for many cellular activities. It has also been used as a cathartic and in alloys.

Magnesium oxide (MgO). An inorganic compound that occurs in nature as the mineral periclase. In aqueous media combines quickly with water to form magnesium hydroxide. It is used as an antacid and mild laxative and has many nonmedicinal uses.

A nutritional condition produced by a deficiency of magnesium in the diet, characterized by anorexia, nausea, vomiting, lethargy, and weakness. Symptoms are paresthesias, muscle cramps, irritability, decreased attention span, and mental confusion, possibly requiring months to appear. Deficiency of body magnesium can exist even when serum values are normal. In addition, magnesium deficiency may be organ-selective, since certain tissues become deficient before others. (Harrison's Principles of Internal Medicine, 12th ed, p1936)

Inorganic compounds that contain magnesium as an integral part of the molecule.

A generic term for a variety of compounds that contain silicon, oxygen, and magnesium, and may contain hydrogen. Examples include TALC and some kinds of ASBESTOS.
