ABSTRACT
BACKGROUND:
The higher level of neutrophil on admission has been reported to predict worse 3-month outcomes in ischemic stroke patients. Our study was to explore the dynamic changes of neutrophil and lymphocyte after r-tPA thrombolysis of ischemic stroke and the relationship with parenchymal hemorrhage (PH) and 3-month function outcome.METHODS:
A total of 208 acute ischemic stroke (AIS) patients with intravenous thrombolysis were included and then received 3-month follow-up in the present study. Blood samples for neutrophil and lymphocyte counts were obtained on admission, at 24 h and at 7 days after r-tPA infusion. The associations of increase in neutrophil, lymphocyte, and neutrophil to lymphocyte ratio (NLR) with PH or 3-month poor outcome were examined by logistic regression.RESULTS:
Increasing trends in the neutrophil and NLR were observed in AIS patients after r-tPA treatment. Increased level of neutrophil at 24 h after r-tPA infusion but not that on admission was associated with PH (OR = 2.86, P = 0.029) and 3-month poorer functional outcomes (OR = 2.67, P = 0.009). Moreover, patients were divided into four groups according to the percent change in neutrophil within 24 h following r-tPA treatment, and we found that there was a trend of incremental OR when compared higher increase group with lower ones.CONCLUSIONS:
Dynamic increase in neutrophil and NLR after stroke may predict PH and 3-month poor outcome in AIS patients receiving r-tPA treatment. Therefore, neutrophil and NLR may serve as activity markers for PH and 3-month poor prognosis in AIS patients with intravenous thrombolysis.Palavras-chave
