Fasting Normoglycemia after Intravenous Thrombolysis Predicts Favorable Long-Term Outcome in Non-Diabetic Patients with Acute Ischemic Stroke.

ABSTRACT: Only a few studies evaluated the role of fasting glucose levels after intravenous thrombolysis (IVT) in patients with acute ischemic stroke (AIS). Importantly, formal analysis concerning the prognostic role of fasting glucose levels in these patients with and without diabetes mellitus (DM) was not performed. Therefore, we assessed whether fasting normoglycemia (FNG) next morning after AIS treated with IVT was associated with 90-day functional outcome in diabetic and non-diabetic patients. We retrospectively analyzed 362 AIS patients treated with IVT at The University Hospital in Krakow. FNG was defined as glucose below 5.5 mmol/L. A favorable outcome was defined as modified Rankin score (mRS) of 0-2 at day 90 after AIS onset. At 3-month follow-up, FNG was associated with favorable outcome (87.5% vs. 60.8%, p < 0.001) and decreased risk of death (3.1% vs. 18.1%, p = 0.002). Independent predictors of a favorable outcome for the whole group were: younger age (HR 0.92, 95%CI 0.89-0.95), lower NIHSS score after IVT (HR 0.70, 95%CI 0.65-0.76), lower maximal systolic blood pressure within 24 h after IVT (HR 0.92, 95%CI 0.89-0.95) and FNG (HR 4.12, 95%CI 1.38-12.35). Association between FNG and mortality was found in univariable (HR 1.47, 95%CI 0.04-0.62) but not in multivariable analysis (HR 0.23, 95%CI 0.03-1.81). In subgroup analyses, FNG was an independent predictor of favorable outcome (HR 5.96, 95%CI 1.42-25.1) only in patients without DM. FNG next morning after IVT is an independent protective factor for a favorable long-term outcome in non-diabetic AIS patients.

Project description:Although stress hyperglycemia represents a main risk factor for poor outcome among patients with acute ischemic stroke (AIS) undergoing recanalization therapy, we have limited information regarding a possible influence of the premorbid diabetic status on this association. We recruited consecutive patients admitted to the Udine University Hospital with AIS who were treated with intravenous thrombolysis (IVT) from January 2015 to September 2020. On the basis of the premorbid diabetic status, our sample was composed of 130 patients with and 371 patients without diabetes. The glucose-to-glycated hemoglobin ratio (GAR) was used to measure stress hyperglycemia. Patients were stratified into 3 groups by tertiles of GAR (Q1-Q3). The higher GAR index was, the more severe stress hyperglycemia was considered. Among diabetic patients we did not observe any significant association between severe stress hyperglycemia and outcome measures (three-month poor outcome: Q1, 53.7%; Q2, 53.5%; Q3, 58.7%; p = 0.854; three-month mortality: Q1, 14.6%; Q2, 9.3%; Q3, 23.9%; p = 0.165; symptomatic intracranial hemorrhage: Q1, 7.3%; Q2, 14%; Q3, 19.6%; p = 0.256). Differently, non-diabetic subjects with more severe stress hyperglycemia showed a higher prevalence of three-month poor outcome (Q1, 32.2%; Q2, 27.7%; Q3, 60.3%; p = 0.001), three-month mortality (Q1, 9.1%; Q2, 8.4%; Q3, 18.3%; p = 0.026), and symptomatic intracranial hemorrhage (Q1, 0.8%; Q2, 0.8%; Q3, 9.9; p = 0.001). After controlling for several confounders, severe stress hyperglycemia remained a significant predictor of three-month poor outcome (OR 2.1, 95% CI 1.03-4.28, p = 0.041), three-month mortality (OR 2.39, 95% CI 1.09-5.26, p = 0.029) and symptomatic intracranial hemorrhage (OR 12.62, 95% CI 1.5-106, p = 0.02) among non-diabetics. In conclusion, premorbid diabetic status seems to influence outcome in AIS patients receiving IVT. Indeed, odds of functional dependency, mortality and hemorrhagic complications were significantly increased in patients with more severe stress hyperglycemia only when they were not affected by diabetes.

Project description:Background and purposeWe aim to investigate whether the higher admission fibrin degradation products (FDPs) levels are associated with parenchymal hematomas (PHs) and unfavorable outcome after intravenous thrombolysis (IVT).MethodsConsecutive patients with acute ischemic stroke treated with IVT were studied. The FDP level was obtained on admission. PH was evaluated 24 h after treatment. The unfavorable outcome was defined as a 90-day modified Rankin Scale >2. The multivariable linear stepwise regression was used to assess independent factors associated with the log-transformed FDP (lgFDP). The receiver operating characteristics (ROCs) curve analysis was used to determine the predictive value of the FDP level for PH and unfavorable outcome. The logistic regression was used to identify independent predictors for PH and unfavorable outcome. The mediation analyses were performed to investigate associations among the FDP level, PH, and outcome.ResultsA total of 181 patients were included in the final analyses [median age, 73 (63-79) years; 102 (56.4%) males; and the median baseline National Institutes of Health Stroke Scale (NIHSS) score, 8 (5-15)]. The lgFDP was independently associated with age (B = 0.011, 95% CI 0.006-0.015, p < 0.001) and the baseline NIHSS score (B = 0.016, 95% CI 0.008-0.025, p < 0.001). The FDP was positively associated with PH [odds ratio (OR) 1.034, 95% CI 1.000-1.069; p = 0.047]. According to the ROC analysis, the best discriminating factor for unfavorable outcome was the FDP ≥3.085 μg/ml. The FDP ≥3.085 μg/ml was an independent predictor of unfavorable outcome (OR 7.086, 95% CI 2.818-17.822; p < 0.001). Mediation analysis revealed that the association of the FDP ≥3.085 μg/ml with unfavorable outcome was not mediated by PH (p = 0.161).ConclusionThe admission FDP levels can predict PH and unfavorable outcome in patients with acute ischemic stroke after IVT. PH does not mediate the effect of the FDP level on the outcome.
