Correlation between eosinophil count and stroke associated-pneumonia in patients with acute ischemic stroke / 国际脑血管病杂志

ABSTRACT

Objective:To Investigate the correlation of eosinophil count and stroke-associated pneumonia (SAP) in patients with acute ischemic stroke.Methods:Patients with acute ischemic stroke within 24 h after onset admitted to the Department of Encephalopathy, Suzhou Integrated Traditional Chinese and Western Medicine Hospital from August 2016 to September 2018 were enrolled prospectively. Their general clinical data and eosinophil counts were collected. National Institutes of Health Stroke Scale (NIHSS) was used to assess the severity of stroke. Multivariate logistic regression analysis was used to determine the independent risk factors for SAP. Results:A total of 521 patients were enrolled, including 106 (20.35%) SAP. Univariate logistic analysis showed that SAP was associated with the classification of eosinophil count (odds ratio [ OR] 0.37, 95% confidence interval [ CI] 0.20-0.68; P=0.001), and tended to be associated with eosinophil count ( OR 0.08, 95% CI 0.01-1.01; P=0.051). Multivariate logistic regression analysis showed that both eosinophil count and eosinophil count classification were not the independent risk factors for SAP, and advanced age ( OR 1.077, 95% CI 1.045-1.109; P< 0.001), chronic obstructive pulmonary disease ( OR 6.931, 95% CI 1.295-37.106; P=0.024) and high baseline NIHSS score ( OR 1.148, 95% CI 1.003-1.314; P=0.045) were significantly independently associated with SAP. Conclusions:Eosinophil count was not an independent predictor of SAP in patients with acute ischemic stroke.
