Abstract:

Background

Early neurological deterioration (END) in acute ischemic stroke is associated with permanent neurological deficits and dysfunction, and considered to be an unstable condition requiring comprehensive medical treatment. Moreover, the relationship between END and glycemic variability (GV) remains unclear.

Objective

To explore the relationship of GV, time in range (TIR) with END in patients with acute ischemic stroke and diabetes, and based on this, to develop a predictive model.

Methods

One hundred and twenty patients with acute ischemic stroke and diabetes (34 with END and 86 without) were selected from the Second Affiliated Hospital of Zhengzhou University from July 2019 to May 2021. Clinical data, GV indices 〔coefficient of variation (CV) , standard deviation (SD) , mean amplitude of glycemic excursion (MAGE) , mean of daily differences (MODD) 〕 and TIR measured by the 72-hour ambulatory continuous glucose monitoring were collected. Factors associated with END were explored by multivariate Logistic regression, and used to develop a nomogram for the prediction of END. ROC analysis was conducted to assess the predictive value of nomogram for END.

Results

Patients with END had higher mean glycosylated hemoglobin (HbA1c) , admission NIH Stroke Scale score, CV, SD, MAGE, and MODD, and lower mean TIR than did those without (P<0.05) . Multivariate Logistic regression analysis indicated that increased CVOR=1.194, 95%CI (1.027, 1.388) , P=0.021〕, SDOR=11.040, 95%CI (1.189, 102.473) , P=0.035〕, MAGE〔OR=3.063, 95%CI (1.062, 8.837) , P=0.038〕, and MODD〔OR=20.990, 95%CI (1.420, 201.206) , P=0.027〕 were associated with elevated risk of END, and prolonged TIR〔OR=0.877, 95%CI (0.789, 0.974) , P=0.014〕 was associated with decreased risk of END. Internal validation of the predictive value of nomogram incorporating CV, SD, MAGE, MODD and TIR for END using bootstrapping showed that its predicted value was basically consistent with the actual value, demonstrating good predictive ability. For estimating END in acute ischemic stroke combined with diabetes, the AUC of CV, SD, MAGE, MODD and TIR was 0.847〔95%CI (0.765, 0.929) , P<0.01〕, 0.812〔95%CI (0.723, 0.901) , P<0.01〕, 0.850〔95%CI (0.772, 0.928) , P<0.01〕, 0.803〔95%CI (0.710, 0.896) , P<0.01〕, and 0.825〔95%CI (0.747, 0.903) , P<0.01〕, respectively.

Conclusion

CV, SD, MAGE, MODD and TIR may be influential factors for END in acute ischemic stroke with diabetes, which could partially predict END. It is of clinical significance to take measures to reduce GV and prolong TIR to prevent END.

摘要:

背景

急性缺血性脑卒中早期神经功能恶化(END)与永久性神经缺陷、功能障碍有关,并且被认为是一种不稳定的情况,需要进行全面的内科治疗。而END与血糖波动之间的关系尚不十分清楚。

目的

探索血糖变异性(GV)、葡萄糖目标范围内时间(TIR)与急性缺血性脑卒中合并糖尿病患者发生END的关系并建立预测模型。

方法

选取2019年7月至2021年5月郑州大学第二附属医院收治的急性缺血性脑卒中合并糖尿病患者120例为研究对象,根据是否发生END分为END组(34例)和非END组(86例)。收集患者临床资料并进行72 h动态血糖监测,记录其GV相关指标〔血糖变异系数(CV)、血糖标准差(SD)、24 h平均血糖波动幅度(MAGE)、日间血糖平均绝对差(MODD)〕及葡萄糖TIR。采用多因素Logistic回归分析探究急性缺血性脑卒中合并糖尿病患者发生END的影响因素,并建立列线图预测模型,采用受试者工作特征(ROC)曲线评估预测价值。

结果

END组糖化血红蛋白(HbA1c)、入院美国国立卫生研究院卒中量表(NIHSS)评分、CVSD、MAGE、MODD均高于非END组,葡萄糖TIR低于非END组(P<0.05)。多因素Logistic回归分析结果显示,CVOR=1.194,95%CI(1.027,1.388),P=0.021〕、SDOR=11.040,95%CI(1.189,102.473),P=0.035〕、MAGE〔OR=3.063,95%CI(1.062,8.837),P=0.038〕、MODD〔OR=20.990,95%CI(1.420,201.206),P=0.027〕升高是急性缺血性脑卒中合并糖尿病患者发生END的危险因素,葡萄糖TIR〔OR=0.877,95%CI(0.789,0.974),P=0.014〕升高是急性缺血性脑卒中合并糖尿病患者发生END的保护因素。基于CVSD、MAGE、MODD及葡萄糖TIR建立急性缺血性脑卒中合并糖尿病患者发生END的列线图预测模型。对该模型采用Bootstrap法进行内部验证,预测值与实际值基本一致,说明该模型具有较好的预测能力。绘制CVSD、MAGE、MODD及葡萄糖TIR预测急性缺血性脑卒中合并糖尿病患者发生END的ROC曲线,结果显示,CVSD、MAGE、MODD、葡萄糖TIR预测急性缺血性脑卒中合并糖尿病患者发生END的ROC曲线下面积(AUC)分别为0.847〔95%CI(0.765,0.929),P<0.01〕、0.812〔95%CI(0.723,0.901),P<0.01〕、0.850〔95%CI(0.772,0.928),P<0.01〕、0.803〔95%CI(0.710,0.896),P<0.01〕、0.825〔95%CI(0.747,0.903),P<0.01〕。

结论

CVSD、MAGE、MODD及葡萄糖TIR可能是急性缺血性脑卒中合并糖尿病患者发生END的影响因素,并对END的发生有一定的预测作用,通过降低GV并增加葡萄糖TIR对预防END发生有一定的临床价值。
