To evaluate the decreasing rate of blood IL-6, β2-MG and PTH in maintenance hemodialysis patients in the 52nd week compared with routine hemodialysis.

394 patients with maintenance hemodialysis were included in the study, and the blood purification time was ≥8 hours per week (including routine hemodialysis, high-throughput hemodialysis, hemodialysis filtration, hemoperfusion, etc.). Randomly assign the control group (197 cases) to receive hemodialysis or hemodialysis filtration treatment, and the frequency of treatment is ≥2 times/week; The experimental group (197 cases) were randomly assigned to receive Jianfan KHA80 hemoperfusion treatment on the basis of hemodialysis or hemodiafiltration treatment, and the frequency of hemoperfusion treatment was ≥2 times/month. The follow-up data of 0, 4, 12, 24, 36 and 52 weeks of treatment in the two groups were collected, and the information of combined medication and adverse events was also collected.
