"Residual Kidney Function and Oxidative Stress in Incremental vs Standard Peritoneal Dialysis (2 Mexican Centers)"

Brief summary (registry, in English)

Title: Comparison of Oxidative Stress and Preservation of Residual Kidney Function Between Incremental and Standard Peritoneal Dialysis in Incident Patients at the Regional General Hospital No. 58 and HGZ/UMF 21 of the Mexican Institute of Social Security (IMSS) in León, Guanajuato BACKGROUND: Peritoneal dialysis (PD) employs hypertonic dextrose-based solutions to remove toxins and excess fluids. This exposure promotes mitochondrial overproduction of reactive oxygen species (ROS), triggers inflammation, and may accelerate the decline of residual kidney function (RKF), leading to complications such as peritonitis, peritoneal fibrosis, and technique failure. Although more biocompatible solutions are available, their high cost and limited accessibility restrict their use in our setting. Incremental peritoneal dialysis (IPD), in contrast to standard peritoneal dialysis (SPD)-which typically involves four daily exchanges with full-dose dialysis-uses reduced dialysis doses tailored to RKF, thereby decreasing glucose exposure. The primary aim of this study was to compare the effects of IPD versus SPD on oxidative stress, inflammation, and the preservation of residual kidney function in incident peritoneal dialysis patients at the Regional General Hospital No. 58 in León, Guanajuato. MATERIALS AND METHODS: A prospective, longitudinal, single-center, open-label, randomized clinical trial will be conducted. Incident peritoneal dialysis patients at the Regional General Hospital No. 58 and Gneral Hospital of Zone Numbre 21 of the Mexican Institute of Social Security (IMSS) who meet the inclusion criteria and provide informed consent will be randomly assigned to either the standard or incremental peritoneal dialysis group. Acute-phase reactants will be measured at baseline and at 3, 6, 9, and 12 months. Oxidative stress will be assessed via baseline and end-of-study malondialdehyde levels. Dialysis and urine Kt/V will be evaluated betwen 6 weeks and 3 moths and 6, 9, and 12 months. Appropriate statistical analyses will be performed thereafter.
