Abstract:Objective To investigate the effect of sequential hemodiafiltration combined with hemoperfusion on patients with diabetic nephropathy and maintenance hemodialysis.Methods Totally 98 patients with diabetic nephropathy maintenance hemodialysis who were treated from March 2018 to March 2019 were selected as the subjects of this study. According to the simple random grouping method, the study subjects were divided into observation group (49 cases) and control group (49 cases). The control group was treated with sequential hemodiafiltration, and the observation group was treated with sequential hemodiafiltration combined with hemoperfusion. The Changes in blood glucose, insulin-related indicators, adipokines, and inflammatory factors were compared between the two groups of patients before and after treatment.Results The fasting blood glucose and 2 h postprandial blood glucose of the observation group after treatment were lower than those of the control group, and the glycated hemoglobin of the observation group after 1 course of treatment was higher than that of the control group (P < 0.05). The observation group had lower insulin resistance index, fasting insulin level, and insulin dosage after one course of treatment than the control group (P < 0.05). The resistin in the observation group after one course of treatment was lower than that in the control group, and the adiponectin level in the observation group was higher than that of the control group after one course of treatment (P < 0.05). The levels of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and C-reactive protein (CRP) in the observation group were lower than those in the control group after 1 course of treatment (P < 0.05).Conclusion In the treatment of patients with diabetic nephropathy and maintenance hemodialysis, the application of sequential hemodiafiltration combined with hemoperfusion can effectively control patients' blood glucose, improve insulin resistance, and regulate the levels of adipokines and inflammatory factors in serum.
