Stress hyperglycemia affecting clinical outcome in ischemic stroke patients

Abstract Background Hyperglycemia is a risk factor for infarct expansion and poor outcome for both diabetic and non-diabetic patients. We aimed to study the prognostic value of stress hyperglycemia on the outcome of acute ischemic stroke patients as regards National Institutes of Health Stroke Scale (NIHSS) as a primary outcome. Results Patients with high random blood sugar (RBS) on admission showed significantly higher values of both median NIHSS score and median duration of hospital stay. There were significant associations between stress hyperglycemia and the risk of 30-day mortality (p < 0.001), the need for mechanical ventilation (p < 0.001) and vasopressors (p < 0.001), and the occurrence of hemorrhagic transformation (p = 0.001). The 24-h RBS levels at a cut off > 145 mg/dl showed a significantly good discrimination power for 30-day mortality (area under the curve = 0.809). Conclusions Stress hyperglycemia had a prognostic value and was associated with less-favorable outcomes of acute stroke patients. Therefore, early glycemic control is recommended for those patients.

Arterial Recanalization

Background: Data on arterial recanalization after IV t-PA treatment are rare. IMS-3 allows the study of variables affecting arterial recanalization after IV t-PA in acute ischemic stroke patients with CTA-proved major artery occlusions. Methods: Of 656 acute ischemic stroke patients in IMS-3, 306 were examined with baseline CTA and randomized either to IV t-PA (N=95) or to IV t-PA followed by digital subtraction angiography (DSA) and endovascular therapy (EVT) (N=211). Comparison of baseline CTA to DSA within 5 hours of stroke onset assessed early arterial recanalization after IV t-PA. A central core lab categorized DSA vessel occlusion as “no, partial, or complete”. We studied the association between arterial occlusion sites on baseline CTA with early recanalization for the endovascular group and analyzed its impact on clinical outcome at 90 days. Results: In the EVT group, 22 patients (10.4%) had no CTA intracranial occlusions, but 1 extracranial occlusion; 42 patients (19.9%) had occlusions of intracranial internal carotid artery (ic-ICA); 10 patients (4.7%) had tandem occlusions of the cervical ICA and middle cerebral artery (MCA); 95 patients (45.0%) had MCA-trunk (M1) occlusions, 33 patients (15.6%) had M2 occlusions, 3 patients (1.4%) had M3/4 occlusions, and 6 patients (2.8%) occlusions within posterior circulation. Partial or complete recanalization occurred in 28.6% of patients before DSA and was marginally associated with occlusion site (p=0.0525) (8 patients (19.0%) with ic-ICA occlusion, 0 patients with tandem ICA/MCA occlusions, 34 patients (35.8%) with M1 occlusions, 11 patients (33.3%) with M2 occlusions, 0 patients with M3/4 occlusions, and 1 patient (16.7%) with occlusion within posterior circulation). Three CTA negative patients had intracranial occlusions on DSA. Thirty-two patients (59.3%) with early recanalization achieved mRS of 0-2 at 90 days compared to 51 patients (38.4%) without early recanalization (p=0.0099). There was no relationship between early recanalization and time to IV t-PA or mean t-PA dose. Conclusion: Before EVT, IV rt-PA may facilitate arterial recanalization and better clinical outcome in about one third of patients.

The Mean

The coronavirus disease 2019 (COVID-19) pandemic has caused millions of deaths worldwide. Acute ischemic stroke is a life-threatening risk factor for COVID-19 infection. Neutrophil-to-lymphocyte ratio (NLR) is one of the predictors of poor prognosis in acute ischemic stroke. The aim of this study was to assess the correlation between NLR values and the clinical outcome of acute thrombotic stroke patients with COVID-19 that was measured using the National Institutes of Health Stroke Scale (NIHSS). A cross-sectional hospital-based study was conducted in Dr. Soetomo General Hospital Surabaya, Indonesia. Patients with acute thrombotic stroke and COVID-19 admitted between 1 March 2020 and 31 May 2021 were recruited. The NLR values and the NIHSS scores were assessed during the admission and the correlation between NLR and NIHSS scores was calculated. This study included 21 patients with acute thrombotic stroke and COVID-19, consisting of 12 males and 9 females. The mean age was 57.6 years old. The mean NLR values was 8.33±6.7 and the NIHSS scores ranging from 1 to 33. Our data suggested a positive correlation between NLR values and NIHSS scores, r=0.45 with p=0.041. In conclusion, the NLR value is potentially to be used as a predictor of the clinical outcome in acute thrombotic stroke patients with COVID-19. However, further study is warranted to validate this finding.

Effect Of Age

BackgroundPatient age and baseline Alberta Stroke Program Early CT score (ASPECTS) are both independent predictors of outcome in acute ischemic stroke patients treated with endovascular therapy (EVT). We assessed the combined effect of age and ASEPCTS on clinical outcome in acute ischemic stroke patients with LVO with and without EVT, and EVT treatment effect in different age/ASPECTS subgroups.MethodsThe HERMES collaboration pooled data of seven randomized controlled trials that tested the efficacy of EVT. Adjusted logistic regression was performed to test for multiplicative interaction of age and ASPECTS with the primary outcome (ordinal mRS) and secondary outcomes (mRS 0–2/0–1/0–3) in the EVT and control arms. Patients were then stratified by age (<75 vs ≥75 years) and ASPECTS (0–5/6–7/8–10), and adjusted effect-size estimates for the association of EVT were derived for the six age/ASPECTS subgroups.Results1735 patients were included in the analysis. There was no multiplicative interaction between age and ASPECTS on clinical outcomes. In the exploratory subgroup analysis, we found a nominally negative point estimate for the association of EVT with clinical outcome in the ASPECTS 0–5/age ≥75, subgroup (acOR 0.36, 95% CI 0.07 to 1.89). The point estimate for moderate outcome (mRS0-3) nominally favored EVT (aOR 1.24, 95% CI 0.16 to 9.84). In all other subgroups, effect size-estimates consistently favored EVT.ConclusionThere was no multiplicative interaction of age and ASPECTS on clinical outcomes in EVT or control arm patients. Outcomes in patients ≥75 years with ASPECTS 0–5 were poor, irrespective of treatment. Further investigation to define the role of EVT and range of acceptable outcomes in this subgroup is warranted.

The Impact

Background: We studied the impact of collateral circulation on CT perfusion (CTP) parametric maps and the amount of salvaged brain tissue, the imaging and clinical outcome at 24 h and at 3 months in a retrospective acute (<3 h) stroke cohort (105 patients) with anterior circulation thrombus treated with intravenous thrombolysis. Methods: Baseline clinical and imaging information were collected and groups with different collateral scores (CS) were compared. Binary logistic regression analyses using good CS (CS ≥2) as the dependent variable were calculated. Results: CTP Alberta Stroke Program Early CT Score (ASPECTS) was successfully assessed in 58 cases. Thirty patients displayed good CS. Poor CS were associated with more severe strokes according to National Institutes of Health Stroke Scale (NIHSS) at arrival (15 vs. 7, p = 0.005) and at 24 h (10 vs. 3, p = 0.003) after intravenous thrombolysis. Good CS were associated with a longer mean onset-to-treatment time (141 vs. 121 min, p = 0.009) and time to CTP (102 vs. 87 min, p = 0.047), better cerebral blood volume (CBV) ASPECTS (9 vs. 6, p < 0.001), better mean transit time (MTT) ASPECTS (6 vs. 3, p < 0.001), better noncontrast CT (NCCT) ASPECTS (10 vs. 8, p < 0.001) at arrival and with favorable clinical outcome at 3 months (modified Rankin Scale ≤2, p = 0.002). The fraction of penumbra that was salvageable at arrival and salvaged at 24 h was higher with better CS (p < 0.001 and p = 0.035, respectively). In multivariate analysis, time from the onset of symptoms to imaging (p = 0.037, OR 1.04 per minute, 95% CI 1.00-1.08) and CBV ASPECTS (p = 0.001, OR 2.11 per ASPECTS point, 95% CI 1.33-3.34) predicted good CS. In similar multivariable models, MTT ASPECTS (p = 0.04, OR 1.46 per ASPECTS point, 95% CI 1.02-2.10) and NCCT ASPECTS predicted good CS (p = 0.003, OR 4.38 per CT ASPECTS point, 95% CI 1.66-11.55) along with longer time from the onset of symptoms to imaging (p = 0.045, OR 1.03 per minute, 95% CI 1.00-1.06 and p = 0.02, OR 1.05 per minute, 95% CI 1.00-1.09, respectively). CBV ASPECTS had a larger area under the receiver operating characteristic curve for good CS (0.837) than NCCT ASPECTS (0.802) or MTT ASPECTS (0.752) at arrival. Conclusions: Favorable CBV ASPECTS, NCCT ASPECTS and MTT ASPECTS are associated with good CS along with more salvageable tissue and longer time from the onset of symptoms to imaging in ischemic stroke patients treated with intravenous thrombolysis.

Stroke Patients

Background: The integrity of collateral circulation is a major prognostic factor in ischemic stroke. Patients with good collateral status have larger penumbra and respond better to intravenous thrombolytic therapy. High systolic blood pressure is linked with worse clinical outcome in patients with acute ischemic stroke treated with intravenous thrombolytic therapy. We studied the effect of different blood pressure parameters on leptomeningeal collateral circulation in patients treated with intravenous thrombolytic therapy (<3 h) in a retrospective cohort. Methods: Anterior circulation thrombus was detected with computed tomography angiography and blood pressure was measured prior to intravenous thrombolytic therapy in 104 patients. Baseline clinical and imaging information were collected. Group comparisons were performed; Collateral Score (CS) was assessed and entered into logistic regression analysis. Results: Fifty-eight patients out of 104 displayed good collateral filling (CS ≥2). Poor CS was associated with more severe strokes according to National Institutes of Health Stroke Scale (NIHSS) at arrival (16 vs. 11, p = 0.005) and at 24 h (15 vs. 3, p < 0.001) after the treatment. Good CS was associated with higher systolic blood pressure (p = 0.03), but not with diastolic blood pressure (p = 0.26), pulse pressure (p = 0.20) or mean arterial pressure (p = 0.07). Good CS was associated with better Alberta Stroke Program Early CT Score (ASPECTS) in 24 h follow-up imaging (p < 0.001) and favorable clinical outcome at three months (mRS ≤2, p < 0.001). Median CS was the highest (CS = 3) when systolic blood pressure was between 170 and 190 mm Hg (p = 0.03). There was no significant difference in the number of patients with good (n = 11) and poor (n = 12) CS who received intravenous antihypertensive medication (p = 0.39) before or during the thrombolytic therapy. In multivariate analysis age (p = 0.02, OR 0.957 per year, 95% CI 0.92-0.99), time from the onset of symptoms to treatment (p = 0.005, OR 1.03 per minute, 95% CI 1.01-1.05), distal clot location (p = 0.02, OR 3.52, 95% CI 1.19-10.35) and systolic blood pressure (p = 0.04, OR 1.03 per unit mm Hg, 95% CI 1.00-1.05) predicted good CS. Higher systolic blood pressure (p = 0.049, OR 0.96 per unit mm Hg, 95% CI 0.93-1.00) and pulse pressure (p = 0.005, OR 0.94 per unit mm Hg, 95% CI 0.90-0.98) predicted unfavorable clinical outcome at three months in multivariate analysis. Conclusion: Moderately elevated systolic blood pressure is associated with good collateral circulation in patients treated with intravenous thrombolytic therapy. However, there is an inverse association of systolic blood pressure with the three-month clinical outcome. Diastolic blood pressure, mean arterial pressure and pulse pressure are not statistically and significantly associated with collateral status.
