Abstract: The objective of this completed, randomized, open-label trial across 11 hemodialysis centers in Shanghai, China, was to evaluate whether hemoadsorption combined with hemodialysis (HAHD) reduces mortality compared to hemodialysis (HD) alone in end-stage kidney disease patients (maintenance HD ≥ 3 months, Kt/V ≥ 1.2). We randomized 1362 patients 1:1 to receive HAHD (n = 683) or HD alone (n = 679; mainly low-flux HD plus intermittent HDF). All 1362 randomized patients were analyzed. The primary outcome was all-cause mortality, while secondary outcomes included cardiovascular mortality and major cardiovascular events. Over a median follow-up of 39.5 months, all-cause mortality occurred in 117 (17.1%) of HAHD patients compared to 144 (21.2%) of HD patients (hazard ratio [HR]: 0.778, 95% confidence interval [CI]: 0.609–0.994; P = 0.045). HAHD also significantly reduced cardiovascular mortality (HR: 0.659, 95% CI: 0.481–0.901; P = 0.009) and major cardiovascular events (HR: 0.772, 95% CI: 0.621–0.959; P = 0.019). Important adverse events, primarily infections and abnormal blood pressure, were comparable between the two groups. Adding hemoadsorption significantly reduced all-cause mortality, cardiovascular mortality, and major cardiovascular events compared to HD alone (mainly low-flux HD plus intermittent HDF). Trial Registration: ClinicalTrials.gov NCT03227770. This randomized open-label trial shows that hemoadsorption combined with hemodialysis reduces all-cause and cardiovascular mortality, and cardiovascular events in patients with end-stage kidney disease compared to hemodialysis (mainly low-flux hemodialysis plus intermittent hemodiafiltration) alone.
