ABSTRACT

【Objective】 To compare the effects of low flux and high flux hemodialysis on insulin resistance (IR), inflammatory factors and coronary artery calcification(CAC) in patients with non-diabetic end-stage renal disease (ESRD), and analyze the related factors affecting the prognosis survival of patients. 【Methods】 A total of 217 patients with non-diabetic ESRD treated in our hospital from February 2015 to April 2017 were selected and randomly divided into control group (n=108) and observation group (n=109) according to the random number table. Low flux and high flux hemodialysis were adopted respectively. Baseline data, renal function, lipid metabolism, inflammatory factors, IR, CAC, complications, outcomes and health and economic benefits of the two groups were compared. The patients were followed up for 3 years and divided into survival group (n=130) and death group (n=75). The clinical data of the two groups were compared and related factors affecting the prognosis and survival were analyzed. 【Results】 Scr, BUN, UAER, TC, TG and LDL-C in the two groups were significantly lower than those before treatment [control group Scr (μmol/L)349.62±37.16 vs 201.73±24.58, BUN (mmol/L) 28.43±5.39 vs20.81±3.47, UAER(μg /min)60.14±11.52 vs 55.73±9.86, TC (mmol/L)5.46±0.93 vs 4.75±0.69, TG (mmol/L)2.58±0.64 vs 2.13±0.57, LDL-C(mmol/L)3.69±0.73 vs 2.45±0.60; observation group Scr (μmol/L) 352.14±38.29 vs 136.85±16.47, BUN (mmol/L) 27.96±5.25 vs17.56±3.68, UAER(μg /min) 60.32±12.07 vs 49.85±7.42, TC (mmol/L)5.48±0.97 vs 4.27±0.56, TG (mmol/L) 2.55±0.62 vs 1.49±0.35, LDL-C(mmol/L) 3.72±0.74 vs1.91±0.48), and eGFR and HDL-C were significantly higher than those before treatment [control group eGFR(mL/min/1.73m)29.32±3.25 vs 72.54±7.86, HDL-C(mmol/L)1.13±0.24 vs1.28±0.31, observation group eGFR(mL/min/1.73m)30.05±3.29 vs 121.63±13.34, HDL-C(mmol/L)1.09±0.22 vs 1.57±0.46), differences between groups were statistically significant (P<0.05); FBG, FINS, HOMA-IR, IL-6, IL-8, TNF-α and hs-CRP in the two groups were significantly lower than those before treatment [control group FBG(mmol/L)4.99±0.95 vs 4.52±0.63, FINS(mU/L)12.93±2.54 vs10.15±2.21, HOMA-IR 2.87±0.54 vs 2.04±0.43, IL-6(pg/mL)120.16±13.54 vs 75.94±9.28, IL-8(mg/L)56.83±6.15 vs 41.52±5.38, TNF-α(ng/L)50.03±5.42 vs 45.62±4.81, hs-CRP(mg/L)26.75±2.79 vs 14.37±2.19; observation group FBG(mmol/L)5.01±0.97 vs 4.11±0.56, FINS(mU/L)13.07±2.62 vs 8.86±1.79, HOMA-IR 2.91±0.55 vs 1.62±0.31, IL-6(pg/mL)119.85±12.91 vs 31.07±4.46, IL-8(mg/L)57.04±6.09 vs 32.65±4.27, TNF-α(ng/L)49.78±5.36 vs 40.15±4.27, hs-CRP(mg/L)23.04±2.82 vs 7.56±1.03], and the CACS score was significantly higher than that before treatment(control group 26.75±2.79 vs 53.68±26.93, observation group 27.04±2.82 vs 75.49±7.66), differences between groups are statistically significant (all P<0.05). Compared with the control group, the total incidence of complications during dialysis was significantly lower in the observation group (P<0.05), and has more economic advantages.Venerable age(OR=1.893, P<0.05), low HDL-C level(OR=0.575, P<0.05), high CACS score(OR=2.384, P<0.05), and high hs-CRP level(OR=3.526, P<0.05) were independent risk factors affecting the survival rate of non-diabetic ESRD patients after dialysis treatment (P<0.05). 【Conclusion】 Compared with low-flux hemodialysis, high-flux hemodialysis has significant effects in improving renal function, lipid metabolism, IR, micro-inflammatory state, and reducing CAC progression and complications, with more prominent cost-effectiveness advantages. HDL-C and Hs-CRP levels and CACS scores of patients should be closely monitored during clinical application, and active preventive measures should be taken to improve the survival rate of patients.
