In this HD/HP vs HD trial, the investigators plan to enroll 410 maintenance hemodialysis patients. Twelve medical centers in the Shanghai metropolitan area have expressed interest in participating. Participants will be randomized into 2 groups after a 1-month washout period. The control group (205 patients) will be treated with hemodialysis or hemofiltration with a frequency of 3 times/week; the experimental group (205 patients) will be treated with Jafron KHA80 hemoperfusion apparatus in addition to hemodialysis or hemofiltration with a frequency of 1 time/week. Follow-up data before the last dialysis at 4, 12, 24, 36 and 52 weeks of treatment were collected from both groups, including the following: routine physical examination, laboratory tests (blood routine, blood biochemistry, β2-MG, PTH, CRP, liver/kidney function, coagulation system tests, etc.), chest X-ray, electrocardiogram and cardiac ultrasound. Dialysis adequacy as defined by standard Kt/V will be calculated. Comorbidities, combined medications and adverse events will also be captured. The primary outcomes will include change in blood β2-MG, PTH and CRP values. Secondary outcomes will include change values for serum protein-bound toxins (e.g., p-Cresol sulfate, indophenol sulphate), improvement in patient quality of life (Kidney Disease Quality of Life Short Form), sleep disturbance (Pittsburgh Sleep Quality Index) and pruritus (Duo's pruritus score).
This multi-center, open-label, randomized, parallel controlled trial aims to investigate the efficacy of hemoperfusion (HP) in combination with hemodialysis (HD) by assessing blood β2-microglobulin (β2-MG), parathyroid hormone (PTH) and C reactive protein (CRP) clearance in maintenance hemodialysis patients.
