Zh Nevrol Psikhiatr Im S S Korsakova 2022 ;122(5):118-122

Peoples' Friendship University, Moscow, Russia.

Supplementation of various substances (metabolites, microelements, vitamins) is sometimes recommended without sufficient indications. To decide whether a supplementation is needed, the question should be answered whether there is a deficiency, and if there is, if it can be compensated by diet. Magnesium (Mg) deficiency has been associated with cardiovascular diseases, certain metabolic and neuropsychiatric disorders. Read More

Measuring magnesium - Physiological, clinical and analytical perspectives.

Clin Biochem 2022 Jul-Aug;105-106:1-15. Epub 2022 Apr 2.

Department of Laboratory Medicine and Pathobiology, University of Toronto, Toronto, ON, Canada; Labortory Medicine Program, Department of Clinical Biochemistry, University Health Network, Toronto, ON, Canada. Electronic address:

Magnesium is the fourth most abundant cation in the human body, essential for physiological processes and is the electrolyte with levels commonly deranged in critically ill patients. These derangements of magnesium imbalance can go unnoticed and result in poor clinical outcomes, requiring both worthy attention to abnormal values and accurate tools and methods to measure magnesium reliably. At present, clinical laboratories employ various methodologies for measuring magnesium in blood and urine. Read More

The emerging role of magnesium in CKD.

Yusuke Sakaguchi

Clin Exp Nephrol 2022 May 25;26(5):379-384. Epub 2022 Jan 25.

Department of Inter-Organ Communication Research in Kidney Diseases, Osaka University Graduate School of Medicine, 2-2 Yamada-oka, Suita, 565-0871, Japan.

Increasing evidence has suggested a clinical relevance of magnesium in the context of vascular calcification and mortality among patients with CKD. Hypomagnesemia is not rare among non-dialysis CKD patients despite their decreased glomerular filtration rates; the prevalence rate was about 15% even in CKD stages G4 and G5. Among several potential causes of hypomagnesemia, tubular dysfunction/interstitial fibrosis may play a pivotal role in the development of hypomagnesemia in CKD, which impairs tubular magnesium reabsorption.
