Magnesium Intake by Enteral Formulation Affects Serum Magnesium Concentration in Patients Undergoing Hemodialysis.

Introduction Decreased serum magnesium levels are associated with mortality and fractures in patients with chronic kidney disease; however, there is no recommendation for Mg intake in these populations. Methods This study used cross-sectional analysis to examine the association between Mg intake and serum Mg levels in patients undergoing hemodialysis. Sixty-one patients were included. Results The daily Mg intake was 185 mg (IQR: 151-203 mg), and serum Mg level was 2.4 mg/dL (IQR: 2.2-2.7 mg/dL). Multiple regression analysis showed that intake of enteral formulation by tube feeding was an independent factor associated with serum Mg level (B = 0.90 [95% confidence interval: 0.61-1.20], p Conclusion These findings may aid in serum Mg level management through diet and enteral formulation in patients undergoing hemodialysis.
