Background and Aims: In experimental models, enhanced inflammation contributes to secondary brain injury in spontaneous intracerebral hemorrhage (ICH). Several inflammatory markers have investigated in humans with inconclusive results. Here, we report the relationship between Systemic Immune-Inflammation (SII) Index and outcome., Methods: We reviewed the medical records of 239 supratentorial spontaneous ICH patients. Patients were dichotomized based on modified Rankin Scale (mRS) at discharge in good (mRS 0-3) and poor (mRS 4-6) outcome. Demographic, clinical, laboratory and imaging data at admission were compared for both groups. SII index was calculated as [(Platelet counts x Absolute Neutrophil Counts (ANC)/Absolute Lymphocyte Counts (ALC))/1000]. Logistic regression analyses were performed to determine the association between markers of inflammation (ANC, ALC, Platelets, SII index) and outcome adjusting for baseline differences., Results: Sixty-two percent of patients had poor outcome (median [IQR] age= 60 [52-71] years). Patients with poor outcome had lower Glasgow coma scale, larger hematoma volumes, and higher incidence of diabetes and intraventricular extension (p<0.05 for each variable). In univariate analysis, ANC and SII index were independently associated with poor outcome (p<0.05). In multivariate analysis, only SII index remained significantly associated with poor outcome (OR=1.34, 95% CI=1.04-1.72, p=0.02). ROC analysis showed that adjusted SII index is a good discriminator for poor outcome (AUC=0.89, 95% CI=0.84-0.93; P <0.0001), with the best cut-off value being 0.73 (Sensitivity 95%, Specificity 71%)., Conclusions: In patients with supratentorial spontaneous ICH early SII index is an independent predictor of poor outcome at time of hospital discharge., Competing Interests: Declaration of Competing Interest None, (Copyright © 2020 Elsevier Inc.

Objective: After an intracerebral hemorrhage, there is an immunological reaction, the specific mechanism of which is not fully understood, that seems to contribute to secondary brain injury. In this study, we investigated alterations of inflammatory markers in the blood and clinical outcome after an intracerebral hemorrhage., Methods: Between July 2013 and February 2016, we performed a prospective study for which we recruited patients who had suffered an intracerebral hemorrhage. Using various scoring scales we evaluated the neurological state upon admission and discharge, and at one and three months following the ICH. During the hospital stay, various inflammatory markers were examined in blood samples., Results: Out of 132 screened patients, 27 were included (48.2% male, mean age 68 years). We found significantly elevated serum concentrations of interleukin-6 (p=0.006) at the time of admission and throughout days three and five. There were also elevated c-reactive protein and granulocyte-colony stimulating factor concentrations found. The concentrations of these immune parameters showed significant monotonic relationships. The ROC analyses showed a better discrimination for mortality with regard to the percentage of T helper cells than with regard to the ICH volume alone., Conclusion: Our results may be regarded as preliminary evidence of the occurrence of inflammation after intracerebral hemorrhage. If there is a relationship between inflammation and clinical outcome remains speculative., (Copyright © 2020 Elsevier Inc. All rights reserved.)

Objective: To study the expression of T cell immunoglobulin and mucin domain 3 (Tim-3) on peripheral blood immunocytes, and the relationship between Tim-3 and the systemic inflammatory response or brain injury in patients with intracerebral hemorrhage (ICH)., Methods: According to the volume of hematoma at 12 hours after onset of ICH, 60 newly diagnosed patients with ICH were divided into the small (volume of hematoma <30 mL, 30 cases) and large (volume of hematoma ≥30 mL, 30 cases) ICH groups. The expression of Tim-3 on peripheral blood immunocytes was analyzed by flow cytometry. Real-time reverse transcriptase polymerase chain reaction was used to detect Tim-3 mRNA on peripheral blood mononuclear cells (PBMCs). Meanwhile, tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and S-100B protein were measured by enzyme-linked immunosorbent assay. Glasgow outcome scale (GOS) score at Day 30 was used to estimate prognosis of patients., Results: The leukocyte count, neutrophil count, monocyte count, TNF-α, IL-1β, and S-100B protein increased remarkably after ICH. However, all of them in the large ICH group increased more obviously, and there were significant differences when compared with those in the small ICH group (P < .01). The expression of Tim-3 mRNA on PBMCs in the large ICH group increased remarkably, peaked at Day 3, and was positively associated with the concentrations of TNF-α, IL-1β, and S-100B protein (P < .01). Tim-3 was predominantly expressed itself on CD14 + monocytes. There was a negative correlation between GOS score and Tim-3 mRNA, TNF-α, IL-1β, or S-100B protein., Conclusions: The expression of Tim-3 on CD14 + monocytes involves in systemic inflammatory reaction after ICH and may be a novel treatment target., (Copyright © 2018 National Stroke Association.

Introduction: Inflammation may determine the prognosis of intracerebral hemorrhage (ICH), which has high mortality and morbidity rates. Recent studies have increasingly demonstrated eosinopenia as a prognostic factor, particularly in bacteremia, chronic obstructive pulmonary disease, and myocardial and cerebral infarction. Nonetheless, its significance regarding the determination of prognosis in patients with ICH has not yet been clarified., Materials and Methods: Our study included 296 patients who presented to our clinic within 24 hours of the onset of symptoms and who were diagnosed with ICH between January 2008 and June 2016, along with 180 age- and sex-matched controls. During their hospitalization, 120 of these 296 patients died. Patients and controls were compared in terms of neutrophil count/percentage and eosinophil count/percentage; these were also compared between nonsurviving and surviving patients. The significance of eosinopenia in predicting mortality was also evaluated., Results: Patients had a significantly higher neutrophil count/percentage and a significantly lower eosinophil count/percentage than controls; these results were similar between nonsurviving and surviving patients (P < .001). Consequently, the patient group was divided into 4 subgroups depending on the presence of eosinopenia and/or neutrophilia. The mortality rate was highest (62%) in the group that had both eosinopenia and neutrophilia. Univariate and multivariate logistic regression analyses indicated that neutrophilia and eosinopenia were independent predictors of mortality in ICH (P = .002; P = .004) DISCUSSION: These results indicate that eosinopenia can occur in patients with ICH and that although the mechanism is unclear, eosinopenia is closely associated with mortality in these patients, particularly when accompanied by neutrophilia., (Copyright © 2017 National Stroke Association.

Background: Acute intracerebral hemorrhage (ICH) is associated with increased susceptibility to bacterial infection. The physiopathology of this phenomenon is not very clear. We conducted a prospective observational study investigating the correlation and independent predictors of infections in patients with ICH., Patients and Methods: Patients admitted between April 1997 and June 2013 with ICH diagnosis were evaluated for inclusion and exclusion criteria., Results: Two hundred twenty-two patients were included in this study. Ninety four patients (42.6%) presented with an infection during hospitalization being more common than pneumonia (30%) and urinary tract infections (14%). Intraventricular hemorrhage (IVH) (95% confidence interval [CI], 62.7% versus 39.3%; P < .001) and higher ICH score (95% CI, 2.31% versus 1.67%; P = .0014) were more common in patients who had infections. We found the following risk factors for having an infection in patients with ICH: IVH (odds ratio [OR] 2.3; 95% IC, 1.3-4.1), each point of ICH score (OR 1.3; 95% CI, 1.1-1.6), and having a hematoma volume larger than 30 cc (OR 2.0; 95% CI, 1.1-3.5). The localization of the hematoma was not found to be relevant., Conclusions: ICH score, size of the hematoma, and presence of IVH are independent risk factors for having an infection after ICH., (Copyright © 2016 National Stroke Association.

A 52-year-old woman was admitted to the hospital with right thalamic hemorrhage. A carotid angiogram revealed occlusion of the terminal portions of the bilateral internal carotid arteries with basal moyamoya vessels, which was diagnosed as moyamoya disease (MMD). At 31 years of age, she was diagnosed with multiple sclerosis because of optic neuritis and myelitis. Paraplegia appeared 14 days after admission. T2-weighted thoracic magnetic resonance imaging revealed a high intensity lesion extending from T4 to T6. Her left upper limb was partially paralytic and her lower limbs exhibited paraplegia and dysesthesia. Anti-aquaporin 4 and anti-Sjögren's syndrome-A and -B antibodies were positive. The pathogenesis of neuromyelitis optica may be associated with such immunologic factors, but there are no reports of simultaneous presentations of neuromyelitis optica and MMD. Autoimmunity may be associated with the etiology of MMD., (Copyright © 2012 National Stroke Association. Published by Elsevier Inc. All rights reserved.)

There is now considerable evidence from both experimental and clinical studies that immune and inflammatory processes can contribute to the onset of stroke and the neurologic and psychologic outcomes. Several specific therapeutic targets have been identified that may significantly improve the devastating impact of stroke.
