Magnesium status, serum HDL cholesterol, and apolipoprotein A-1 levels

Area of Science:

• Biochemistry
• Clinical Nutrition
• Nephrology

Background:

• Magnesium is crucial for numerous enzymatic reactions and cellular processes.
• Dyslipidemia, characterized by abnormal lipid levels, is a significant risk factor for cardiovascular disease.
• The relationship between magnesium status and lipid profiles requires further elucidation.

Purpose of the Study:

• To investigate the association between magnesium status and serum lipid profiles in patients with microscopic hematuria.
• To compare lipid and apolipoprotein levels between patients with low magnesium status and those with normal magnesium status.

Main Methods:

• A cohort of 27 patients with microscopic hematuria and normal renal function was studied.
• Patients were categorized into two groups based on magnesium retention determined by a magnesium-loading test: low magnesium status (n=7) and normal magnesium status (n=20).
• Serum lipid profiles (cholesterol, HDL cholesterol) and apolipoproteins (A-1, B) were measured and compared between the groups.

Main Results:

• Patients with low magnesium status exhibited significantly lower serum concentrations of total cholesterol, HDL cholesterol, and apolipoprotein A-1 compared to those with normal magnesium status.
• No significant differences were observed in serum magnesium levels or apolipoprotein B concentrations between the two groups.
• These findings indicate a specific association between magnesium deficiency and reduced HDL cholesterol and apolipoprotein A-1.

Conclusions:

• Magnesium deficiency is associated with unfavorable lipid profiles, specifically lower levels of HDL cholesterol and apolipoprotein A-1.
• These results highlight the potential role of magnesium in lipid metabolism and cardiovascular health.
• Further research is warranted to explore the therapeutic implications of correcting magnesium status in dyslipidemic individuals.
