摘要:
目的 针对老年糖尿病肾病(DN)维持性血液透析(MHD)患者进行高通量透析(HFHD)治疗,评估治疗对患者心功能超声指标、血清心肌损伤及炎症生化指标的远期改善作用。 方法 选择2022年3月—2023年3月于温州市中西医结合医院接受MHD治疗的93例老年DN患者,根据患者需要和透析目的将其分为HFHD组42例和低通量透析(LFHD)组51例,并分别进行高通量透析和低通量透析。追踪治疗效果1年,并于追踪期结束比较患者组内、组间心功能超声指标、血清心肌损伤、炎症生化指标以及不良反应发生率差异。 结果 组内比较结果显示:治疗后,HFHD组患者左室舒张末期内径(LVDD)降低,左室射血分数(LVEF%)与舒张早期E峰值与舒张晚期A峰值的比值(E/A)上升,血清超敏肌钙蛋白Ⅰ(hs-TNⅠ)水平也呈现上升趋势(P<0.05);LFHD组hs-TNⅠ、Hcy、超敏C反应蛋白(hs-CRP)水平显著上升(P<0.05)。组间比较结果显示:治疗后,HFHD组LVDD、室间隔舒张期厚度(IVSDT)较LFHD组显著下降,LVEF%和E/A较LFHD组显著上升;HFHD组血清肌酸激酶同工酶质量(CK-MBmass)、hs-TNⅠ、同型半胱氨酸(Hcy)以及hs-CRP水平均显著低于LFHD组。HFHD组透析不良反应总发生率为11.90%(5/42),显著低于LFHD组[47.06%(24/51),P<0.001]。 结论 老年糖尿病肾病维持性血液透析患者行高通量透析治疗,可有效改善心功能,延缓心肌损伤水平,且安全性较高。 Abstract:Objective High-flux hemodialysis (HFHD) was performed in elderly patients with diabetic nephropathy (DN) maintenance hemodialysis (MHD) to evaluate the long-term improvement of cardiac function ultrasound index, serum myocardial injury, and inflammatory biochemical index. Methods A total of 93 elderly patients with DN who received MHD treatment in Wenzhou Chinese and Western Medicine Hospital from March 2022 to March 2023 were selected and divided into a HFHD group (n=42) and a low-flux dialysis (LFHD) group (n=51) according to patients' needs and dialysis purposes. High-flux dialysis and low-flux dialysis were performed respectively, and the treatment effect was followed up for 1 year. At the end of the follow-up period, the differences in cardiac function ultrasound indexes, serum myocardial injury, inflammatory biochemical indexes, and incidence of adverse reactions were compared between the two groups. Results The results of intra-group comparison showed that; after treatment, the left ventricular end-diastolic diameter (LVDD) in the HFHD group decreased, the left ventricular ejection fraction (LVEF%) and the ratio of early diastolic E peak to late diastolic A peak (E/A) increased, and the serum high-sensitivity troponin Ⅰ (hs-TNⅠ) level also showed an upward trend (P < 0.05). The levels of hs-TNⅠ, Hcy, and hs-CRP in the LFHD group were significantly increased (P < 0.05). The results of inter-group comparison showed that after the treatment, LVDD and interventricular septum diastolic thickness (IVSDT) in the HFHD group were significantly lower than those in the LFHD group, while LVEF% and E/A were significantly higher than those in the LFHD group. The levels of serum creatine kinase isoenzyme mass (CK-MBmass), hs-TNⅠ, homocysteine (Hcy), and hypersensitive C-reactive protein (hs-CRP) in the HFHD group were significantly lower than those in the LFHD group. The total incidence of dialysis adverse reactions in the HFHD group was 11.90% (5/42), which was significantly lower than that in the LFHD group (47.06%, 24/51, P < 0.001). Conclusion HFHD treatment in elderly DN MHD patients can effectively improve cardiac function and delay myocardial injury with high safety. -
