Serum miR-195 and miR-599 predict the outcome of patients with acute ischemic stroke / 国际脑血管病杂志

ABSTRACT

Objective:To investigate the predicting value of serum miR-195 and miR-599 for the outcome of patients with acute ischemic stroke (AIS).Methods:Patients with AIS admitted to Danzhou People's Hospital from January 2018 to July 2020 were enrolled prospectively. The modified Rankin Scale was used to evaluate the outcome of patients at 14 d after onset or when they were discharged from the hospital. A score of 0-2 was defined as a good outcome and a score of >2 were defined as a poor outcome. Multivariate logistic regression analysis was used to determine the independent risk factors for poor outcome of patients with AIS. Receiver operating characteristic (ROC) curve analysis was used to determine the predictive value of serum miR-195 and miR-599 for the poor outcome of patients with AIS. Results:A total of 158 patients with AIS were enrolled. Their age was (65.80±12.36) years old, 105 were males (66.46); 95 patients (60.1%) had a good outcome, and 63 patients (39.9%) had a poor outcome. The age, total cholesterol, triglycerides, low-density lipoprotein cholesterol, baseline National Institutes of Health Stroke Scale (NIHSS) score, serum miR-195 and miR-599 levels in the poor outcome group were significantly higher than those of the good outcome group ( P<0.05). Multivariate logistic regression analysis showed that age (odds ratio [ OR] 1.984, 95% confidence interval [ CI] 1.315-3.617; P=0.036), low-density lipoprotein cholesterol ( OR 2.108, 95% CI 1.406-4.103; P=0.013), baseline NIHSS score ( OR 2.584, 95% CI 1.675-4.505; P=0.005), serum miR-195 ( OR 3.927, 95% CI 2.615-8.227; P<0.001) and miR-599 ( OR 2.952, 95% CI 1.973-6.114; P<0.001) were the independent risk factors for the poor outcome of patients with AIS. ROC curve analysis showed that the area under the curve (0.938, 95% CI 0.882-0.997) of serum miR-195 combined with miR-599 for predicting poor outcome was significantly higher than that predicted alone, and its predictive sensitivity and specificity were 97.0% and 87.4% respectively. Conclusions:The higher levels of serum miR-195 and miR-599 are associated with the poor outcome of patients with AIS. The combination of the both had good predictive value for the poor outcome of patients with AIS.
