Abstract
To investigate the possible relationship between procalcitonin (PCT) and stroke-associated pneumonia (SAP) as well as clinical outcomes after recombinant tissue plasminogen activator (rt-PA) treatment of AIS. From June 2015 to December 2019, 173 consecutive patients with AIS after IV rt-PA treatment were prospectively enrolled. Serum PCT concentrations were measured after admission. Multivariate logistic regression analysis was used to examine the potential risk factors of SAP, poor outcome and mortality. Of the 173 patients, 49 (28.3%) participants were identified with SAP, 87 (50.3%) with poor outcome, and 28 (16.2%) with mortality. Multivariate logistic regression analysis demonstrated that patients with PCT in the second [odds ratio (OR) 4.413; 95% confidence interval (CI) 1.331–14.634; P = 0.015] and third tertile (OR 10.958; 95% CI 3.524–34.071; P < 0.001) were more likely to have SAP compared with the first tertile. Besides, PCT was an independent predictor of 3-month poor outcome (OR 3.219, 95% CI 1.291–8.028, P = 0.007) and mortality (OR 7.538, 95% CI 2.061–27.564, P = 0.002). In receiver operating characteristic (ROC) curve analysis, the diagnostic and prognostic accuracy of PCT was higher than hs-CRP. This study demonstrated that PCT was a reliable diagnostic and prognostic biomarker of SAP and poor clinical outcomes in Chinese AIS patients after IV rt-PA treatment.Keywords
