Background: We sought to investigate whether admission hyperglycaemia is associated with complications in patients who had an acute ischaemic stroke (AIS) treated with intravenous recombinant tissue plasminogen activator and, if so, whether complications during hospitalisation modify the effect of hyperglycaemia on 3-month poor outcome after thrombolysis., Methods: Patients who were diagnosed with AIS after thrombolysis between July 2016 and January 2019 were enrolled in this study. Five prespecified complications, including infections, brain oedema, deep vein thrombosis (DVT), haemorrhagic transformation (HT) and gastrointestinal bleeding, were recorded during hospitalisation., Results: Of 388 patients, 143 (36.86%) presented with hyperglycaemia. Patients with hyperglycaemia were more likely to experience one or more complications than patients without hyperglycaemia. After adjustment for potential confounders, hyperglycaemia was associated with brain oedema (OR 2.39; 95% CI 1.08 to 5.30), HT (OR 2.16, 95% CI 1.06 to 4.41), symptomatic intracerebral haemorrhage (sICH) (OR 7.32, 95% CI 2.35 to 22.80) and gastrointestinal bleeding (OR 3.62; 95% CI 1.93 to 6.80), but was not linked to infections (OR 1.48, 95% CI 0.76 to 2.9) and DVT (OR 0.60, 95% CI 0.23 to 1.5). Additional adjustment for the complications in the clinical outcome analysis, done to assess these complications as an intermediate in the pathway from admission hyperglycaemia to clinical outcome, did not substantially change the model (all p for interaction >0.05)., Conclusion: Hyperglycaemia is an independent predictor of complications following stroke after thrombolysis, especially for brain oedema, gastrointestinal bleeding, HT and sICH.

Introduction: Increased neutrophil-to-lymphocyte ratio (NLR) and hyperglycemia on admission are associated with poor outcomes in acute ischemic stroke (AIS) patients. We sought to evaluate the combined effect of increased NLR and hyperglycemia on the prognosis of ischemia stroke treated with intravenous thrombolysis (IVT)., Methods: Patients with acute ischemic stroke receiving IVT treatment were prospectively enrolled. All participants were followed for 3 months. According to the levels of NLR and blood glucose, patients were categorized into four groups: high NLR or nonhigh NLR with or without hyperglycemia. The associations between NLR values with or without hyperglycemia and outcomes of stroke after thrombolysis were assessed by multivariable logistic regression analysis., Results: Among the 381 stroke patients (median age 68 years, 61.68% man) included, 155 (40.68%) had a poor outcome (modified Rankin Scale score 3-6) during 3 months. After multivariate adjustment, high NLR with hyperglycemia increased the risk of 3-month poor outcome (OR = 4.42; 95% CI, 2.13-9.16), early neurological deterioration (END) (OR = 4.81; 95% CI, 2.08-11.12), and 3-month mortality (OR = 6.56; 95% CI, 1.92-22.40). A significant multiplicative interaction of NLR and blood glucose on 3-month poor outcome in ischemic stroke patients after thrombolysis was observed., Conclusions: Ischemic stroke patients with concurrent high NLR and hyperglycemia increased risks of END, 3-month poor outcome, and mortality after thrombolysis., (© 2020 The Authors.

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.
