摘要:

目的 探讨糖尿病肾病(diabetic kidney disease,DKD)患者认知功能障碍与人β淀粉样蛋白1-42(human β Amyloid 1-42,Aβ1-42)的关系。方法 选取2020年5月至2021年5月在徐州医科大学附属医院内分泌科治疗的2型糖尿病(type 2 diabetes mellitus,T2DM)患者161例,根据尿白蛋白/肌酐比值(urine albumin creatine ratio,UACR)水平分为正常白蛋白尿(DM)组(n=60)、微量白蛋白尿(DKD1)组(n=58)和大量白蛋白尿(DKD2)组(n=43)。采用蒙特利尔认知评估(Montreal Cognitive Assessment,MoCA)量表评估患者认知功能。检测患者Aβ1-42、UACR、胱抑素C(Cystatin C,CysC)、估算肾小球滤过率(estimated glomerular filtration rate,eGFR),并分析上述指标与MoCA评分的关系。结果 与DM组比较,DKD1和DKD2组CysC、Aβ1-42均升高(P<0.05),eGFR降低(P<0.05)。与DKD1组比较,DKD2组CysC升高(P<0.05),eGFR降低(P<0.05)。与DM组相比,DKD1组、DKD2组MoCA评分均降低(P<0.05)。与DKD1组比较,DKD2组MoCA评分降低(P<0.05)。3组MoCA评分与Aβ1-42、UACR、CysC呈负相关(均P<0.01),与eGFR呈正相关(P<0.01)。3组Aβ1-42与UACR、CysC呈正相关(均P<0.01),与eGFR呈负相关(P<0.01)。多因素线性回归分析结果显示,Aβ1-42、UACR是影响DKD患者MoCA评分的影响因素,Aβ1-42、UACR水平越高,MoCA评分越低,患者认知功能越差。结论 DKD患者存在认知功能障碍,与Aβ1-42水平及肾损害严重程度密切相关。

Abstract:

Objective To investigate the relationship between cognitive dysfunction and human β Amyloid 1-42 (Aβ1-42) in patients with diabetic kidney disease (DKD). Methods In this study, patients(n=161) with type 2 diabetes mellitus (T2DM) who were treated in the Department of Endocrinology, Affiliated Hospital of Xuzhou Medical University from May 2020 to May 2021 were as subjects. These patients were enrolled into normoalbuminuria (DM) group (n=60), microalbuminuria (DKD1) group (n=58) and macroalbuminuria (DKD2) group (n=43) according to urine albumin creatine ratio(UACR)levels. The patients' cognitive function was assessed by the Montreal Cognitive Assessment (MoCA) scale. Aβ1-42, UACR, Cystatin C (CysC), estimated glomerular filtration rate (eGFR) were detected, and the relationship between the above indicators and MoCA score was analyzed.Results Compared with DM group, CysC and Aβ1-42 in DKD1 and DKD2 groups increased (P<0.05), and eGFR decreased (P<0.05). Compared with DKD1 group, CysC increased and eGFR drcreased in DKD2 group(P<0.05). The MoCA scores in the DKD groups were superior to those in DM group (P<0.05), which in the DKD2 group were prevalent (P<0.05). MoCA scores in the three groups were negatively correlated with Aβ1-42, UACR, and CysC (all P<0.01), and positively correlated with eGFR (P<0.01). Aβ1-42 in the three groups was positively correlated with UACR and CysC (all P<0.01), and negatively correlated with eGFR (P<0.01). The results of multivariate linear regression analysis showed that Aβ1-42 and UACR were the influencing factors for MoCA score in DKD patients. Conclusion Cognitive dysfunction exists in DKD patients, which is closely related to the level of Aβ1-42 and the severity of renal damage.
