Study on diagnostic value of procalcitonin and T cell subsets in infection after acute cerebral infarction / 重庆医学

ABSTRACT

Objective To study the diagnostic value of procalcitonin and T cell subsets in infection after acute cerebral infarction(ACI).Methods One hundred and twenty-two patients with ACI in our hospital from February 2015 to January 2016 were selected and divided into the infection group(60 cases) and non-infection group(62 cases) according to whether infection occurring.The systolic blood pressure,diastolic blood pressure,body temperature,NI H SS score,cerebral infarction location,procalcitonin,CD4 level,CD8 level were compared between the two groups.The Logistic regression analysis was performed.Results The NIHSS score in the infection group was (14.9 ± 5.7) points,which was significantly higher than (10.6-4-3.8) points in the non-infection group,the differences were statistically significant (P＜0.05).The number of pons infarction in the infection group accounted for 35.48 ％ (22/60),which was significantly higher than 17.74 ％ (11/62) in the non-infection group,the differences were statistically significant(P＜0.05).The procalcitoninl level in the infection group was significantly higher than that in the non-infection group,while the levels of CD4 and CD8 were significantly lower than those in the non-infection group,the differences were statistically significant (P＜0.05).The multivariate Logistic regression analysis showed that the risk factors affecting infection after cerebral infarction included pons infarction,NIHSS score,procalcitonin,CD4 and CD8 levels.Conclusion Detecting procalcitonin and T cell subsets in the patients with ACI in clinical work is conducive to predict the infection occurrence.
