Clinical Efficacy and Long-term Prognosis of High Flux Hemodialysis Combined with Different Frequency Hemodiafiltration in the Treatment of Middle-Aged and Elderly Patients with Uremia

Abstract

Introduction. To analyze the clinical efficacy and long-term prognosis of high flux hemodialysis (HFHD) combined with different frequency hemodiafiltration (HDF) in uremic patients. Methods. 86 middle-aged and elderly patients with uremia were divided into the HF group (HFHD combined with high-frequency HDF) and the LF group (HFHD combined with low-frequency HDF). The changes between the two groups in various indicators after 12 months of dialysis and the survival rate at 5 years of follow-up were compared. We used SPSS 25.0 software for data analysis. Results. The differences of the levels of serum albumin, hemoglobin and transferrin in HF Group was significantly higher than LF Group before and after treatment (P < .05). The differences of the levels and clearance rate of calcium, phosphorus, parathyroid hormone, β2-microglobulin and cysteine protease inhibitor C in the patients’ blood after dialysis were significantly higher in HF Group than in LF Group (P < .05). The all-cause mortality rate, new cardiovascular event rate, new cerebrovascular event rate, and new infection event rate of HF Group were significantly lower than those of LFHD group, respectively (P < .05). The LF Group had a significantly higher risk of all-cause mortality events, new cardiovascular cerebrovascular and infectious events than the HF Group (P < .05). Conclusion. 1 week/time HDF combined with HFHD can more effectively eliminate the vascular related toxins in middle-aged and elderly patients with uremia, improve their nutritional status, treatment effect, and long-term prognosis.
