Objective: Our study investigated the association between level of HbA1c (glycated hemoglobin) at admission and the prognosis of aneurysmal subarachnoid hemorrhage (SAH). Methods: A total of 510 patients treated with neuro-intervention for aneurysmal SAH and with data for admission HbA1c (glycated hemoglobin) were included. Favorable clinical outcome was defined as Modified Rankin Scale (mRS) score of 0–2 at 3 months. Receiver operating characteristic (ROC) curve analysis was used to identify the optimal cutoff value of HbA1C for unfavorable clinical outcomes. Logistic regression was used to evaluate the association between HbA1C level and outcomes. Results: The optimal cutoff value of HbA1C was identified as 6.0% (P < 0.001), and patients with a high HbA1C (≥ 6.0%) had a lower prevalence of favorable clinical outcomes than patients with low HbA1C (< 6.0%) (P < 0.001). High HbA1C (≥ 6.0%) was independently associated with unfavorable clinical outcome (OR 2.84; 95% CI: 1.52-5.44; P = 0.004). The risk of unfavorable clinical outcome was significantly increased in patients with HbA1C (≥ 7.0%, < 8%) and HbA1C (≥ 8.0%) compared with lower baseline HbA1C (≥ 6.0%, < 7%) values (OR 2.17; 95% CI: 1.87-5.13; P = 0.011 and OR 4.25; 95% CI: 3.17-8.41; P = 0.005). Conclusions: Our study showed that HbA1C could be an independent predictor of worse outcome following neuro-intervention for aneurysmal SAH. High HbA1C (≥ 6.0%) was associated with unfavorable clinical outcome, and gradual elevation of HbA1C contributed to an increase in the risk of worse clinical outcome after SAH.

Object. In this study the authors evaluated the relative role of cerebral hemodynamic impairment (HDI) in the pathogenesis of delayed cerebral ischemia and poor clinical outcome after aneurysmal subarachnoid hemorrhage (SAH). Methods. Cerebral hemodynamics were assessed daily with transcranial Doppler (TCD) ultrasonography in 55 consecutive patients with verified SAH. Hemodynamic impairment was defined as blood flow velocity (BFV) values consistent with vasospasm in conjunction with impaired autoregulatory vasodilation as evaluated using the transient hyperemic response tests in the middle cerebral arteries. A total of 1344 TCD examinations were performed, in which the evaluation of HDI was feasible during 80.9% and HDI was registered during 12% of the examinations. It was found that HDI occurred in 60% of patients and was frequently recorded in conjunction with severe vasospasm (p < 0.05) and a rapid increase of BFV values (p < 0.05). Detection of HDI was closely associated with the development of delayed ischemic brain damage after SAH (p < 0.05). Furthermore, because delayed ischemia was never observed in cases in which vasospasm had not led to the development of HDI, its occurrence increased significantly the likelihood of subsequent cerebral ischemia among the patients with vasospasm (p < 0.05). Detection of HDI was independently related to unfavorable clinical outcome according to Glasgow Outcome Scale at 6 months after SAH (p < 0.05). Conclusions. The results showed that HDI is common after SAH and can be evaluated with TCD ultrasonography in routine clinical practice. Detection of HDI could be useful for identifying patients at high or low risk for delayed ischemic complications and unfavorable clinical outcome after SAH.

Objective: Systemic inflammation after subarachnoid hemorrhage (SAH) is implicated in delayed cerebral ischemia (DCI) and adverse clinical outcomes. We hypothesize that early changes in peripheral leukocytes will be associated with outcomes after SAH.Methods: SAH patients admitted between January 2009 and December 2016 were enrolled into a prospective observational study and were assessed for Hunt Hess Scale (HHS) at admission, DCI, and modified Ranked Scale (mRS) at discharge. Total white blood cell (WBC) counts and each component of the differential cell count were determined on the day of admission (day 0) to 8 days after bleed (day 8). Global cerebral edema (GCE) was assessed on admission CT, and presence of any infection was determined. Statistical tests included student's t-test, Chi-square test, and multivariate logistic regression (MLR) models.Results: A total of 451 subjects were analyzed. Total WBCs and neutrophils decreased initially reaching a minimum at day 4–5 after SAH. Monocyte count increased gradually after SAH and peaked between day 6–8, while basophils and lymphocytes decreased initially from day 0 to 1 and steadily increased thereafter. Neutrophil to lymphocyte ratio (NLR) reached a peak on day 1 and decreased thereafter. WBCs, neutrophils, monocytes, and NLR were higher in patients with DCI and poor functional outcomes. WBCs, neutrophils, and NLR were higher in subjects who developed infections. In MLR models, neutrophils and monocytes were associated with DCI and worse functional outcomes, while NLR was only associated with worse functional outcomes. Occurrence of infection was associated with poor outcome. Neutrophils and NLR were associated with infection, while monocytes were not. Monocytes were higher in males, and ROC curve analysis revealed improved ability of monocytes to predict DCI and poor functional outcomes in male subjects.Conclusions: Monocytosis was associated with DCI and poor functional outcomes after SAH. The association between neutrophils and NLR and infection may impact outcomes. Early elevation in monocytes had an improved ability to predict DCI and poor functional outcomes in males, which was independent of the occurrence of infection.

Objective: With the aging of the world population, the number of elderly patients suffering from aneurysmal subarachnoid hemorrhage (aSAH) is gradually growing. We aim to investigate the potential association between plasma ALT level and clinical complications of elderly aSAH patients, and explore its predictive value for clinical outcomes of elderly aSAH patients. Methods: Between January 2013 and March 2018, 152 elderly aSAH patients were analyzed in this study. Clinical information, imaging findings and laboratory data were reviewed. According to the Glasgow Outcome Scale (GOS), clinical outcomes at 3 months were classified into favorable outcomes (GOS 4-5) and poor outcomes (GOS 1-3). Logistic regression analysis was used to assess the indicators associated with poor outcomes, and receiver curves (ROC) and corresponding area under the curve (AUC) were used to detect the accuracy of the indicator. Results: A total of 48 (31.6 %) elderly patients with aSAH had poor outcome at 3 months. In addition to ICH, IVH, Hunt-Hess 4 or 5 Grade and Modified Fisher 3 or 4 Grade, plasma ALT level was also strongly associated with poor outcome of elderly aSAH patients. After adjusting for other covariates, plasma ALT level remained independently associated with pulmonary infection (OR 1.05; 95% CI 1.00–1.09; P = 0.018), cardiac complications (OR 1.05; 95% CI 1.01–1.08; P = 0.014) and urinary infection (OR 1.04; 95% CI 1.00–1.08; P = 0.032). Besides, plasma ALT level had a predictive ability in the occurrence of systemic complications (AUC 0.676; 95% CI: 0.586– 0.766; P<0.001) and poor outcome (AUC 0.689; 95% CI: 0.605–0.773; P<0.001) in elderly aSAH patients. Conclusion: Plasma ALT level of elderly patients with aSAH was significantly associated with systemic complications, and had additional clinical value in predicting outcomes. Given that plasma ALT levels on admission could help to identify high-risk elderly patients with aSAH, these findings are of clinical relevance.

Introduction: To report clinical outcome of aneurysmal subarachnoid hemorrhage (aSAH) patients exposed to cerebral vasospasm (CVS) targeted treatments in a systematic review and meta-analysis and compare the efficacy of endovascular and non-endovascular treatments in severe / refractory vasospasm patients. Methods: The literature was searched using PubMed, EMBASE, and The Cochrane Library database. Eligibility criteria were (1) Rated clinical outcome; (2) at least 10 patients; (3) aSAH; (4) study published in English or French (January 2006 - October 2014); and (5) methodological quality score > 10, according to STROBE criteria. Endpoint included unfavorable outcome rate, defined as mRS 3-6, GOS 1-3 or GOSE 1-4 at latest follow-up. Analyses included stratification per route of administration (oral, i.v., intra-arterial or cisternoventricular) and per study inclusion criteria (severe, CVS, refractory CVS or high risk for CVS). Univariate and multivariate subgroup analyses were performed to identify interventions associated with a better outcome. Results: Sixty-two studies, including 26 randomized controlled trials, were included (8976 patients). Overall 2490 patients had unfavorable outcome including death (random-effect weighted average: 33.7%, 99%CI, 28.1-39.7%; Q-value: 806.0, I 2 =92.7%). Clinical outcome was significantly better in severe or refractory patients for whom, on top of best medical treatment, endovascular intervention was performed (RR=0.76, IC95% [0.66-0.89], p <0.00001) whereas other route of administration didn’t show significant differences. RR of unfavorable outcome was significantly lower, vs control groups, in patients treated with Cilostazol (RR=0.46 (IC99% [0.25-0.85], P = 0.001, Q value 1.5, I 2 = 0). Conclusion: In case of CVS following aSAH, endovascular treatment in severe / refractory vasospasm patients. including intra-arterial injection of pharmacological agents or balloon angioplasty, improves outcome as compared to other route of administration.
