摘要:
回顾性分析2014年1月至2016年12月山西医科大学第一医院肾内科治疗的24例原发性甲状腺功能减退症(甲减)肌病致急性肾损伤(AKI)患者的临床资料,其中男性8例,女性16例,年龄24~ 68岁,按照改善全球肾脏病预后组织标准分为AKI Ⅰ期组(9例)及AKIⅡ期组(15例),以同期21例无合并AKI甲减肌病患者为对照组.结果:(1)对照、AKI Ⅰ和Ⅱ期组血肌酐[(63.1±12.7)、(133.6±13.7)和(240.0±74.3) μmol/L]、尿素氮[(5.5±1.1)、(8.0±2.7)和(13.0±8.0) mmol/L]、白蛋白[(42.3±4.8)、(37.7±4.3)和(38.0±3.7)g/L]、CK[(711±403)、(1 056±609)和(1 619±986)U/L]、CK同工酶(CK-MB)[(55.2±17.1)、(55.6±32.5)和(106.6±82.1)U/L]、LDH[(443±177)、(472±185)和(552±186)U/L]、AST[(23.4±6.0)、(71.6±8.2)和(226.8±86.3)U/L]及ALT[(21.7±8.7)、(81.2±18.7)和(101.2.9±39.2)U/L]水平比较,差异均有统计学意义(均P<0.05);(2)人工神经网络分析显示,肌红蛋白标准化的重要性为100%,与血肌酐变化密切相关;(3)多元线性回归分析显示,CK-MB(B=2.10,SE=0.38,β=0.96,t=5.52)、LDH(B=0.18,SE=0.06,β=0.34,t=3.00)及AST(B=0.16,SE=0.09,β=0.32,t=2.62)是血肌酐水平变化的相关因素(均P<0.05).提示甲减肌病是AKI发生的主要危险因素,AKI的严重程度可能与甲减肌病程度相关.%Clinical data of 24 patients with acute kidney injury (AKI) induced by hypothyroidism myopathy admitted in our hospital from January 2014 to December 2016 were analyzed retrospectively.There were 9 patients classified as AKI stage Ⅰ and 15 patients as AKI stage Ⅱ according to the Kidney Disease Improving Global Outcomes (KDIGO),21 hypothyroidism myopathy patients without AKI were selected as control group.ANOVA and chi-square test were used to compare the general data and laboratory results among three groups;artificial neural network analysis and multi-factor stepwise regression method were used to analyze the factors related to AKI.There were significant differences in serum creatinine (Scr) (F=34.3,P<0.01),BUN(F=29.1,P<0.01),ALB(F=5.27,P=0.01),CK(F=8.61,P=0.01),creatin kinase isoenzyme(CK-MB)(F=33.1,P<0.01),LDH(F=7.78,P=0.01),ALT(F=34.3,P<0.01) and AST (F=28.1,P<0.01) among three groups.Artificial neural network analysis showed that myoglobin was closely related to serum creatinine,suggesting its importance for AKI in patients with primary hypothyroidism myopathy.Multivariate regression analysis showed that serum creatinine was correlated with CK-MB(B=2.10,SE=0.38,β=0.96,t=5.52),LDH(B=0.18,SE=0.06,β=0.34,t=3.00)and AST(B=0.16,SE=0.09,β=0.32,t=2.62).This study indicates that hypothyroidism myopathy may be one of the causes of AKI,and the severity of AKI might be closely related to the severity of hypothyroidism myopathy.
