Predictive effect of hypersensitive C-reactive protein and neutrophil and lymphocyte ratio on the prognosis of young patients with ischemic stroke
摘要
Abstract
Objective To investigate the predictive effect of hypersensitive C-reactive protein(Hs-CRP)and neutrophil and lymphocyte ratio(NLR)on the prognosis in young patients with ischemic stroke. Methods From October 2016 to October 2017,110 consecutive young patients(18-45 years old)with ischemic stroke admitted to the Department of Neurology,Xuanwu Hospital,Capital Medical University were enrolled retrospectively. According to the modified Rankin scale(mRS)scores,they were divided into either a good prognosis group(mRS≤2;n=90)or a poor prognosis group(mRS>2;n=20).The patients completed the related examinations within 24 h after admission,including blood routine and Hs-CRP.The NLR value was calculated according to the count of neutrophils and lymphocyte in blood routine.The age,gender,underlying diseases(hypertension,diabetes,hyperlipidemia,hyperhomocysteinemia),histories of smoking and drinking,National Institutes of Health stroke scale(NIHSS)scores of both groups of patients were documented.The poor prognosis after discharge at 90 d was used as the dependent variable,the independent variables of P<0.05 in univariate analysis were further performed with multivariate logistic regression analysis.The receiver operating characteristic(ROC)curve was used to evaluate the sensitivity and specificity of the independent risk factors. The Youden index was calculated and the optimal cut-off value was determined. Results (1)Compared with the good prognosis group,the poor prognosis group had higher NIHSS score,NLR and Hs-CRP at admission.The differences between the 2 groups were statistically significant(9.0[4.5,13.0]vs.2.5[2.0,4.0],2.97[2.31,4.20]vs.2.13[1.76,2.70],4.65 [2.70,9.52]mg/L vs.2.06[0.87,4.54]mg/L;all P<0.05).There were no significant differences in other baseline data and clinical characteristics between the two groups(all P>0.05).(2)The results of the multivariate logistic regression analysis indicated that the high level of Hs-CRP(OR,1.086,95%CI 1.009-1.169)and higher NIHSS score(OR,1.487,95%CI 1.229-1.797)at admission were the independent risk factors for poor prognosis(all P < 0. 05),and there was no significant relation between NLR and prognosis(P>0.05).(3)The area under the ROC curve of the Hs-CRP levels at admission was 0.722(95%CI 0.591-0.853,P=0.002).When the predictive value of Hs-CRP level at admission was 3.365 mg/L,the maximum Youden index was 0.367,its corresponding sensitivity was 70.0%and specificity was 66.7%. Conclusions The higher Hs-CRP level and NIHSS score at admission may independently predict the poor prognosis of young patients with ischemic stroke at 90 d after discharge to a certain extent.It is not appropriate to use Hs-CRP≥3.365 mg/L alone for poor prognosis screening,but NLR may not be associated with the prognosis at admission.关键词
