Hypomagnesemia is reported in patients who use proton pump inhibitors (PPIs). We investigated the effect of PPIs use on serum magnesium levels in hemodialysis patients. Our study was conducted in a hemodialysis center including 75 end stage renal disease patients. PPI use and duration were investigated. All patients were dialyzed using a dialysate magnesium level of 0.5-0.75 mmol/L. After at least one month of hemodialysis with the mentioned dialysate, laboratory tests were performed.

There was no significant difference between serum magnesium levels of patients who used and did not use PPIs (2.73 ± 0.3 vs. 2.88 ± 0.3 mg/dL, P = ns). There were 15 patients (20%) with a dialysate magnesium level of 0.5 mmol/l and 60 patients (80%) with a dialysate magnesium level of 0.75 mmol/L. The mean serum magnesium levels of patients with a dialysate magnesium level of 0.5 mmol/L was 2.45 ± 0.3 mg/dL while that of patients with a dialysate magnesium level of 0.75 mmol/L was 2.85 ± 0.3 mg/dL (P<0.0001). In hemodialysis patients, PPI use did not affect serum magnesium levels. The most important factor affecting the serum magnesium levels in hemodialysis patients is the dialysate magnesium concentration.
