[摘要] 目的 探讨高通量血液透析对非糖尿病维持性血液透析(MHD)患者血清颗粒蛋白前体(PGRN)及胰岛素抵抗的影响。 方法 入选非糖尿病MHD患者60例,随机分为高通量透析组(n=30)和普通透析组(n=30),同时选择年龄、性别相匹配的20例健康体检者作为对照组。两透析组随访6个月,使用稳态模型胰岛素抵抗指数(HOMA-IR)评估胰岛素抵抗,采用ELISA法测定治疗前后血PGRN、白细胞介素-6(IL-6)水平,并记录超敏C反应蛋白(hs-CRP)、血总钙、血磷、甲状旁腺素(PTH)、血脂、单室模型尿素清除指数(spKt/V)等指标的变化。 结果 与对照组相比,高通量透析组和普通透析组患者HOMA-IR均明显升高(P<0.05)。治疗后高通量透析组的HOMA-IR、PGRN、IL-6、hs-CRP、血磷、甘油三酯、总胆固醇较治疗前显著下降(P<0.05),亦明显低于普通透析组(P<0.05)。而普通透析组的HOMA-IR、PGRN、IL-6、hs-CRP、血磷、甘油三酯、总胆固醇等指标治疗前后差异无统计学意义(P>0.05)。 结论 高通量透析能降低非糖尿病MHD患者血清PGRN水平,改善机体炎症状态及胰岛素抵抗。

[Abstract] Objecfive To investigate the effect of high-flux hemodialysis on serum progranulin and insulin resistance in non-diabetic patients with maintenance hemodialysis(MHD). Methods A total of 60 non-diabetic patients with maintenance hemodialysis were randomly divided into high-flux hemodialysis group(n=30) and common dialysis group(n=30). Another 20 healthy subjects matched for age and sex served as control group. Insulin resistance were assessed by homeostasis model assessment of insulin resistance index(HOMA-IR). Serum progranulin and interleukin-6(IL-6) before and after treatment of 6 months were determined by ELISA. High sensibility C-reactive protein(hs-CRP), total serum calcium, serum phosphate(P), parathroid hormone(PTH), Serum triglyceride(TG), total cholesterol,high density lipoprotein cholesterol, low density lipoprotein cholesterol,and single pool KT/V(spKt/V) were also recorded. Result Compaired with the control group, HOMA-IR in high-flux hemodialysis group and common dialysis group was significantly higher at baseline. After treatment of six months, HOMA-IR,serum progranulin, IL-6, hs-CRP, P, TG, TC were significantly reduced in high-flux hemodialysis group(P<0.05), and lower than those in the common dialysis group(P<0.05). whereas the differences were no statistically significant changes of HOMA-IR, PGRN, IL-6, hs-CRP, P, TG, TC in common dialysis group(P>0.05). Conclusions High-flux dialysis could reduce serum level of progranulin, proinlammatory state and insulin resistance in non-diabetic patients with maintenance hemodialysis.

颗粒蛋白前体(PGRN)是新近发现的一种重要促炎症脂肪因子,文献报道在肥胖、2型糖尿病、多囊卵巢综合症等疾病中,高水平的PGRN与机体胰岛素抵抗呈显著正相关[1,2]。而CKD患者随着肾功能减退,血清PGRN水平逐渐升高,高水平的PRGN参与机体普遍存在的微炎症状态及胰岛素抵抗成为近年研究的热点[3,4]。高通量血液透析具有更大的超滤系数和吸附功能,能更好地清除尿毒症毒素及多种炎症介质,使用高通量血液透析对血清PGRN水平的影响目前报道很少。本研究通过与普通血液透析比较,初步阐述高通量血液透析对非糖尿病MHD患者血清PGRN水平及胰島素抵抗的影响。……
