ABSTRACT

Objective:To investigate the predictive value of YKL-40 at admission on stroke-associated pneumonia (SAP) and poor outcome in patients with acute ischemic stroke (AIS).Methods:Patients with AIS admitted to Taixing People’s Hospital from February 2020 to March 2021 were enrolled prospectively. The poor outcome was defined as 3-6 points on the modified Rankin Scale at 90 d after onset. Multivariate logistic regression analysis was used to determine the independent predictors of SAP and poor outcome, and the predictive value of serum YKL-40 on SAP and poor outcome was evaluated by receiver operating characteristic (ROC) curve. Results:A total of 377 patients with AIS were enrolled. The median serum YKL-40 was 127.16 μg/L. One hundred and four patients (27.6%) had SAP, and 126 (33.4%) had poor outcomes at 90 d after onset. Multivariate logistic regression analysis showed that after adjusting for confounding factors, YKL-40 was the independent predictors of SAP (odds ratio [ OR] 1.005, 95% confidence interval [ CI] 1.003-1.008; P=0.001) and poor outcome at 90 d ( OR 1.009, 95% CI 1.006-1.011; P=0.001). The ROC curve analysis showed that the area under the curve of YKL-40 for predicting SAP was 0.769 (95% CI 0.713-0.824; P<0.001), the best cutoff value was 168.70 μg/L, and the sensitivity and specificity were 71.2% and 75.1% respectively; the area under the curve of YKL-40 for predicting poor outcome at 90 d was 0.787 (95% CI 0.735-0.840; P<0.001), the best cutoff value was 195.56 μg/L, and the sensitivity and specificity were 68.3% and 84.1% respectively. Conclusion:Higher serum YKL-40 at admission has a good predictive value for SAP and poor outcome at 90 d in patients with AIS.

ABSTRACT

Objective:To investigate the predictive value of serum hypersensitive C-reactive protein (hs-CRP) for stroke-associated pneumonia (SAP) in patients with acute ischemic stroke (AIS) who received intravenous thrombolysis.Methods:From May 2015 to April 2017, the clinical data of the patients with AIS treated with intravenous thrombolysis in Nanjing First Hospital were collected retrospectively. Multivariate logistic regression analysis was used to determine the independent risk factors for SAP in patients with AIS after intravenous thrombolysis. Receiver operating characteristic (ROC) curve and nomogram-based methods were used to analyze the predictive value of hs-CRP for SAP. Results:A total of 243 patients with AIS who received intravenous thrombolysis were included, and 63 (34.6%) of them had SAP. There were significant differences in age ( P=0.006), leukocyte count ( P=0.044), fasting blood glucose level ( P=0.003), serum hs-CRP level ( P=0.001), hs-CRP classification ( P=0.001) and dysphagia rate ( P=0.035) between the SAP group and non-SAP group. Multivariate logistic regression analysis showed that after adjusting for the confounding factors, taking the first quartile of serum hs-CRP level as a reference, the third quantile (odds ratio [ OR] 18.790, 95% confidence interval [ CI] 4.771-74.007; P=0.001) and the fourth quantile ( OR 54.054, 95% CI 12.248-324.088; P=0.001) of hs-CRP were the independent predictors of SAP. The area under the ROC curve of the baseline serum hs-CRP level for predicting SAP was 0.805 (95% CI 0.742-0.868; P<0.001). When the optimal cut-off value of hs-CRP was 5.54 mg/L, the sensitivity and specificity of predicting SAP were 76.11% and 76.19%, respectively. The analysis of nomogram also showed that hs-CRP was an independent predictor of SAP (consistency index 0.862, 95% CI 0.738-0.986; P<0.001). Conclusions:The increased serum hs-CRP was an independent predictor of SAP in patients with AIS receiving intravenous thrombolysis, and had a higher predictive value.
