After baseline measurements were taken, the dialysate sodium concentration was reduced from 140 to 137 mEq/L. Oxidative stress parameters and flow-mediated dilatation (FMD %) were measured before and after 6 months of HD with low sodium dialysate. Interdialytic weight gain (IDWG) and pre- and post-dialysis BP were monitored during the study. A total of 52 patients were enrolled and 41 patients completed the study. There was a significant reduction in systolic blood pressure at the end of the study [130.00 (90.00-190.00) vs. 120.00 (90.00-150.00), p < 0.001]. Similarly, there were significant improvements in IDWG [2670.00 (1670.00-4300.00) vs. 1986.00 (1099.00-3998.00), p < 0.001] and FMD % [7.26 (4.55-8.56) vs. 9.56 (6.55-12.05), p < 0.001]. Serum MDA levels (p < 0.001) were significantly decreased; serum SOD (p < 0.001) and GPx (p < 0.001) activities were significantly increased after low sodium HD compared to standard sodium HD. Our data seem to suggest a potential role of 137 mEq/L sodium dialysate for improving hemodynamic status, endothelial function and reducing oxidative stress than 140 mEq/L sodium dialysate in maintenance HD patients.eninfo:eu-repo/semantics/closedAccessDialysate SodiumEndothelial DysfunctionHemodialysisOxidative StressArticle4810Q3Q21699170427473155WOS:000384563100021
