Zieve et al., in 1977, found in severe magnesium (Mg) deficiency protein synthesis in many tissues reduced, and DNA synthesis increased, The increase in splenic DNA synthesis in the presence of depressed protein synthesis may be an early stage in a lymphoproliferative process leading ultimately to neoplasia. The interaction of Mg and Vitamin D is well known; Mg is a cofactor for binding, transport, and conversion process of Vitamin D in the liver and renal organ. Studies show high Mg intake was associated with reduced risk of Vitamin D deficit or insufficiency. Plasma Mg levels of 0.79–0.76 mmol/L (1.9–1.8 mg/dL) have been classified as inadequate and levels <0.76 mmol/L as deficient.
The aim of this study is to determine the serum Mg level in three categories of Vitamin D deficiency (<20ng/mL), insufficiency (20-30 ng/mL), and sufficiency (>30ng/mL) groups [Table 1]. Mg less than 1.9 mg/dL considered as hypomagnesemia, and this study shows the prevalence of hypomagnesemia in Vitamin D deficiency, insufficiency, and sufficiency was 35%, 20%, and 3%. Comparison of the laboratory test was done by t-independent test in patients with Mg levels higher and lower/equal than 1.9 mg/dL, and the results show higher fasting blood sugar and lower phosphor, Vitamin D, blood urea nitrogen and albumin in cases with hypomagnesemia (=1.9 mg/dL) [Table 2].
Hypomagnesemia is relatively common in the general population ranging from 2.5% to 15% because of inadequate Mg intake, increased gastrointestinal or renal loss, or redistribution from extracellular to intracellular space. Mg can improve Vitamin D metabolism, PTH response and reverse the resistance to Vitamin D treatment. Improvement in Mg status leads to an increase in Vitamin D binding protein synthesis and, in turn, an elevated transport of Vitamin D3 to the liver and 25 (OH)-D to the kidney. Vitamin D can help Mg balance by enhancing absorption and increasing the urinary Mg excretion.
This study shows serum albumin and serum vitamine D can be effected by serum Mg level while more deeply drop of serum Mg level leads to decrease serum phosphor and serum level and increase blood sugar. Part of these may be related to the primary role of Mg in Vitamin D regulation and metabolism and its important role for protein synthesis in many tissues.
| Conclusion|| |
This study shows Mg level lower than 1.9 mg/dL is associated with diverse metabolic derangement in hemodialysis patients, hypovitaminosis D occur in 70% (deficient: 54% and insufficient 16%) and Hypomagnesemia (<1.9 meq/dL) was seen in 16%. Hypomagnesemia may be a primary event that accelerates hypovitaminosis D, hypoalbuminemia, that ultimately lead to hypophosphatemia and higher fasting blood sugar in profound deficiency. In all dialysis paying attention to Mg level as a cardiovascular, metabolism, and cognition regulator is necessary, especially in low Vitamin D level situations.
I dedicate this study to the soul of Dr. Mohammad Mosadegh, God bless his soul.
