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, ß2-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.  DOI 10.52547/ijkd.7864.
