Brief Summary:
This is an open-label, randomized, crossover study to evaluate the efficacy of extending the duration of hemoadsorption (HA) combined with hemodialysis (HD) from 2 hours to 4 hours for clearing protein-bound uremic toxins, such as Indoxyl Sulfate (IS), in stable maintenance hemodialysis patients. Patients will be randomized to receive either 2-hour HA or 4-hour HA once a week for 8 weeks, then cross over to the other treatment for another 8 weeks after a 2-week washout period. The primary endpoint is the reduction rate of IS.
Detailed Description:
Patients with end-stage renal disease (ESRD) on maintenance hemodialysis (MHD) have a high burden of uremic toxins, particularly protein-bound uremic toxins (PBUTs), which are poorly cleared by conventional dialysis and are associated with high cardiovascular mortality. hemoadsorption (HA) is an adjunctive blood purification technique effective at removing PBUTs. The standard duration for HA sessions is typically 2-2.5 hours. However, emerging evidence suggests that extending the treatment duration may enhance toxin removal. This study aims to rigorously compare the efficacy and safety of a 4-hour HA session combined with hemodialysis against a standard 2-hour session in clearing key PBUTs like Indoxyl Sulfate (IS) and p-Cresyl Sulfate (PCS). The findings will provide crucial evidence for optimizing HA treatment protocols to improve toxin clearance and potentially patient outcomes in the ESRD population.
