Abstract
OBJECTIVE Spontaneous intracerebral hemorrhage (ICH) poses a public health issue due to its elevated mortality rates. The International Normalized Ratio-platelet index (INR-Plt index) has recently been recognized as a predictive factor for liver disease progression. The potential of applying the INR-Plt index in forecasting ICH prognosis presents an intriguing subject. This study endeavors to examine the correlation between the INR-Plt index and hospital outcomes in patients with spontaneous supratentorial ICH. METHODS A retrospective examination of 283 adult ICH patients was undertaken. The INR-Plt index was computed using the formula: [INR/platelet counts (1000/μL)] × 100. The clinical outcomes evaluated consisted of mortality rates and the Modified Rankin Scale (mRS) at discharge. An unfavorable outcome was defined as an mRS score from 4 to 6. RESULTS The study found a significant correlation between the INR-Plt index and hospital mortality (odds ratio: 4.31, 95% CI: 1.07-17.31, P = 0.04). There was a 43% rise in mortality risk for every 0.1 unit increase in the INR-Plt index. Kaplan-Meier survival curves illustrated a considerably lower survival rate at discharge for patients with an INR-Plt index >0.8 (log-rank test: P = 0.047). Regarding unfavorable outcomes, the INR-Plt index was not a significant factor according to logistic regression analyses. CONCLUSIONS The INR-Plt index is a predictor of hospital mortality in patients with spontaneous supratentorial ICH. A higher INR-Plt index value is associated with an increased risk of mortality, underlining the potential usefulness of this composite index in guiding clinical decision-making and enabling risk stratification.

Abstract
Objective Inflammation participates in the pathology and progression of secondary brain injury after intracerebral hemorrhage (ICH). This meta-analysis intended to explore the prognostic role of inflammatory indexes, including neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), white blood cell (WBC), and C-reactive protein (CRP) in ICH patients. Methods Embase, PubMed, Web of Science, and Cochrane Library were searched until June 2023. Two outcomes, including poor outcome and mortality were extracted and measured. Odds ratio (OR) and 95% confidence interval (CI) were presented for outcome assessment. Results Forty-six studies with 25,928 patients were included in this meta-analysis. The high level of NLR [OR (95% CI): 1.20 (1.13-1.27), p < 0.001], WBC [OR (95% CI): 1.11 (1.02-1.21), p = 0.013], and CRP [OR (95% CI): 1.29 (1.08-1.54), p = 0.005] were related to poor outcome in ICH patients. Additionally, the high level of NLR [OR (95% CI): 1.06 (1.02-1.10), p = 0.001], WBC [OR (95% CI): 1.39 (1.16-1.66), p < 0.001], and CRP [OR (95% CI): 1.02 (1.01-1.04), p = 0.009] were correlated with increased mortality in ICH patients. Nevertheless, PLR was not associated with poor outcome [OR (95% CI): 1.00 (0.99-1.01), p = 0.749] or mortality [OR (95% CI): 1.00 (0.99-1.01), p = 0.750] in ICH patients. The total score of risk of bias assessed by Newcastle-Ottawa Scale criteria ranged from 7-9, which indicated the low risk of bias in the included studies. Publication bias was low, and stability assessed by sensitivity analysis was good. Conclusion This meta-analysis summarizes that the high level of NLR, WBC, and CRP estimates poor outcome and higher mortality in ICH patients.

Abstract
OBJECTIVE To investigate the prognostic value of inflammatory markers, including neutrophil/lymphocyte ratio (NLR), derived neutrophil/lymphocyte ratio (dNLR), platelet/lymphocyte ratio (PLR), monocyte/lymphocyte ratio (MLR), prognostic nutritional index (PNI), and systemic inflammation response index (SIRI) in patients with aneurismal subarachnoid hemorrhage (aSAH), and then develop a Nomogram prognostic model. METHODS We analysed 178 aSAH patients who underwent surgery at Subei People's Hospital of Jiangsu province from January 2015 to December 2017. Patients were divided into two groups according to Glasgow outcome scale (GOS) score at 3 months. Univariate and multivariate analysis were used to identify the association between inflammatory markers and prognosis. Subsequently, we identified the best cutoff of SIRI for unfavorable outcome using receiver operating characteristic (ROC) curve analysis and compared the clinical data between high and low SIRI levels. We further evaluated the additive value of SIRI by comparing prognostic nomogram models with and without it. RESULTS A total of 47 (26.4%) patients had a poor outcome. Multivariate logistic regression analysis showed that SIRI was an independent risk factor of poor outcome. The SIRI of 4.105 × 109/L was identified as the optimal cutoff value, patients with high SIRI levels had worse clinical status and higher rates of unfavorable outcome. ROC analysis showed that a nomogram model combining the SIRI and other conventional factors showed more favorable predictive ability than the model without the SIRI. CONCLUSIONS SIRI was independently correlated with unfavorable outcome in SAH patients, and the nomogram model combining the SIRI had more favorable discrimination ability.

Abstract
Background Neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) play an important role in the inflammatory response in various diseases, but the role in the course of spontaneous intracerebral hemorrhage (ICH) is unclear. Methods This study retrospectively collected baseline characteristics and laboratory findings, including NLR and PLR at different time points, from spontaneous ICH patients undergoing surgery between January 2016 and June 2021. Patients were scored using the modified Rankin Scale (mRS) to evaluate their functional status at 30 days post-operation. Patients with mRS score ≥3 were defined as poor functional status, and mRS score <3 was defined as good functional status. The NLR and PLR were calculated at admission, 48 h after surgery and 3-7 days after surgery, respectively, and their trends were observed by connecting the NLR and PLR at different time points. Multivariate logistic regression analysis was used to identify independent risk factors affecting the prognosis of ICH patients at 30 days after surgery. Results A total of 101 patients were included in this study, and 59 patients had a poor outcome at 30 days after surgery. NLR and PLR gradually increased and then decreased, peaking at 48 h after surgery. Univariate analysis demonstrated that admission Glasgow Coma Scale (GCS) score, interval from onset to admission, hematoma location, NLR within 48 h after surgery and PLR within 48 h after surgery were associated with poor 30-day prognosis. In multivariate logistic regression analysis, NLR within 48 h after surgery (OR, 1.147; 95% CI, 1.005, 1.308; P, 0.042) was an independent risk factor for 30-day after surgery prognosis in spontaneous ICH patients. Conclusion In the course of spontaneous intracerebral hemorrhage, NLR and PLR initially increased and subsequently decreased, reaching their peak values at 48 h after surgery. High NLR within 48 h after surgery was an independent risk factor for poor prognosis 30 days after surgery in spontaneous ICH patients.

Abstract
Objective The purpose of this study was to explore the predictive value of the neutrophil-to-lymphocyte ratio (NLR) on 30-day outcomes in patients with spontaneous intracerebral hemorrhage (ICH) after surgical treatment. Methods This retrospective study utilized data from patients with ICH who underwent craniotomy or minimally invasive puncture and drainage (MIPD) between January 2015 and June 2021. The patients meeting the inclusion criteria were divided into two groups according to 30-day outcomes, namely, the favorable outcome group and the poor outcome group. Sex, age, time from onset to admission, vital signs at admission, admission Glasgow Coma Scale (GCS) score, diabetes mellitus, hypertension, hematoma volume, hematoma location, surgical approach, and NLR at different time points were all recorded and analyzed. Results A total of 128 patients were finally enrolled in this study, including 32 and 96 patients in the favorable outcome group and the poor outcome group, respectively. During the course of ICH, the changing trend of NLR was to increase first and then decrease and peaked within 48 h after surgery. In the univariate analysis, systolic blood pressure, admission GCS score, hematoma volume, surgical approach, and NLR within 48 h after surgery were statistically significant. In the multivariable analysis, NLR within 48 h after surgery (odds ratio [OR] = 1.342, p < 0.001) was an independent risk factor of the 30-day outcomes in patients with ICH after surgical treatment. The receiver operating characteristic (ROC) analysis showed that the best predictive cut-off value for NLR within 48 h after surgery was 12.35 [sensitivity 82.9%, specificity 81.8%, and area under the curve (AUC) 0.877] and 14.46 (sensitivity 55.1%, specificity 87.5%, and area under the curve 0.731) for the MIPD group and the craniotomy group, respectively. Conclusions In the process of ICH, the value of NLR was increased first and then decreased and peaked within 48 h after surgery. NLR within 48 h after surgery was an independent risk factor of the 30-day outcomes in patients with ICH. The peak NLR >12.35 or 14.46 in patients receiving MIPD or craniotomy reflected a poor prognosis, respectively.

Abstract
The neutrophil-to-lymphocyte ratio (NLR) plays an important role in the progression of intracerebral hemorrhage (ICH). An increasing number of studies have reported that a high NLR is correlated with poor clinical outcomes among patients with ICH. Here, we conducted a systematic review and meta-analysis to evaluate the prognostic value of NLR in the setting of ICH. We performed a comprehensive search of electronic literature databases to identify all relevant studies evaluating the prognostic role of NLR in patients with ICH. Two researchers independently screened the studies and extracted relevant data. We extracted, pooled, and weighted odds ratio (OR) and 95% confidence interval (CI) values using a generic inverse-variance method, and then evaluated the heterogeneity among studies using Q test and I2 statistic. Finally, we selected a total of 26 studies including 7,317 patients for the current study. Overall, our results indicated that a high NLR was significantly associated with a poor outcome (OR, 1.32; 95% CI, 1.19–1.46; P < 0.00001), mortality (OR, 1.05; 95% CI, 1.01–1.09; P = 0.02), and neurological deterioration (OR, 1.65; 95% CI, 1.08–2.52; P = 0.02). We did not observe a significant association between NLR and hematoma expansion (OR, 1.04; 95% CI, 0.99–1.08; P = 0.09). Our study indicated that a high NLR is significantly associated with poor clinical outcomes in patients with ICH. As NLR is a simple and easily available biomarker, future studies should focus on exploring its application in the prognostic evaluation of patients with ICH.

Abstract
Background. Intracerebral hemorrhage (ICH) accounts for 10-20% of all strokes and is associated with high morbidity and mortality. Recent studies have identified serum biomarkers as a means to improve outcome prognostication in poor grade ICH patients. Poor prognosis of ICH patients and complex pathophysiology of the disease necessitate prognostic serum biomarkers to help guide treatment recommendations. Objective. The objective is to systematically review all biomarkers used to predict long-term functional outcome in patients with spontaneous intracerebral hemorrhage. Results. We identified 36 studies investigating the predictive utility of 50 discrete biomarkers. Data from 4865 ICH patients were reviewed. Inflammatory biomarkers (11/50) were most often studied, followed by oxidative (8/50), then neuron and astrocyte-specific (7/50). S100 calcium binding protein B, white blood cell count, and copeptin were the most often studied individual biomarkers. The prognostic utility of 23 biomarkers was analyzed using receiver operating characteristic curves. Area under the curve (AUC) values for all available biomarkers except neutrophil/lymphocyte ratio were acceptable. Twenty of the 23 biomarkers were characterized by at least one excellent AUC value. Vascular endothelial growth factor, glial fibrillary astrocyte protein, and S100 calcium binding protein B were characterized by outstanding AUC. Conclusions. We identified the inflammatory and neuron and astrocyte-specific biomarker categories as having the greatest number of significant individual biomarker predictors of long-term outcome. Further investigation utilizing cross-validation of prediction models in a second independent group and blinded assessment of outcomes for the predictive utility of biomarkers in patients with ICH is warranted.

Abstract
OBJECTIVE Growing evidence suggests that lymphocytopenia on admission (LOA) is associated with infectious complications and poor outcomes in intracerebral hemorrhage (ICH). Whether LOA preferentially increases the risk for community acquired infections or nosocomial infections is unknown. This study investigates the relationship between LOA and nosocomial infections in a cohort of patients with ICH in a safety-net hospital. MATERIAL AND METHODS This is a single center, observational, retrospective study of 213 patients with non-traumatic ICH admitted to the neurocritical care unit between 2008 and 2014. Patients' clinical, demographic, lab and radiologic data were retrieved from institutional electronic medical records. Nosocomial infection was defined as clinical onset 48 h after admission. RESULTS Prevalence of LOA was 24.8%. Patients with LOA showed significant associations with mechanical ventilation (67.9% versus 49.4%; p= 0.019), higher median ICH score (2 versus 1; p=0.006), nosocomial infection (43.4% versus 28.0%; p=0.038), nosocomial UTI (24.5% versus 8.9%; p=0.003). Adjusting for baseline covariates in a multivariate logistic regression, we observed an association of LOA with nosocomial UTI (OR, 3.66 [95% CI, 1.36-9.88], p=0.010). From the Cox proportional model, patients with LOA had 1.76 times the hazard of developing of nosocomial infection, compared to those without LOA ([95% CI: 1.01, 3.07], p=0.046) and had 3.27 times the hazard of developing nosocomial UTI, compared to those without LOA ([95% CI: 1.39, 7.67], p=0.007). CONCLUSIONS This study is the first to show that LOA is associated with nosocomial urinary tract infections and significantly shorter times to develop nosocomial infections.

Abstract
Hematological abnormalities at admission are common after traumatic brain injuries and are associated with poor outcomes. The objective of this study was to identify the predictive factors of mortality among patients who underwent emergency surgery for the evacuation of epidural hematoma (EDH) or subdural hematoma (SDH).This was a single-center retrospective cohort study of 200 patients who underwent emergency surgical evacuation of EDH or SDH between September 2010 and December 2018. Data on hematological parameters and clinical and intraoperative features were collected. The primary end-point was 1-year mortality after surgery. Univariate and multivariate analysis were performed, and the receiver operating characteristic (ROC) curves were assessed.Of the 200 patients included in this study, 102 (51%) patients died within 1 year of emergency surgery. Lymphocyte count at admission, creatinine levels, activated partial thromboplastin time (aPTT), age, intraoperative epinephrine use, and Glasgow Coma Scale (GCS) score were significantly associated with mortality in the multivariate analysis. The areas under the ROC curve for the GCS score, aPTT, and lymphocyte counts were 0.677 (95% confidence interval [CI] 0.602-0.753), 0.644 (95% CI 0.567-0.721), and 0.576 (95% CI 0.496-0.656), respectively.Patients with elevated lymphocyte counts on admission showed a higher rate of 1-year mortality following emergency craniectomy for EDH or SDH. In addition, prolonged aPTT and a lower GCS score were also related to poor survival.

[PMID: 32922951 PMCID: PMC7398197 DOI: 10.1186/s41016-020-00201-5] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2019] [Accepted: 05/10/2020] [Indexed: 12/18/2022] Open
Abstract
Our study aimed to determine the effect of the neutrophil–lymphocyte ratio on the prognosis of adult patients with acute stroke. We searched the Web of Science, PubMed, Embase, Cochrane Library, and China National Knowledge Infrastructure databases and selected all of the potentially eligible studies. From the included studies, we extracted characteristics such as the stroke type and acquisition time until routine blood collection and the odds ratios across studies. The 95% confidence intervals and odds ratios were pooled to calculate the effect size for the neutrophil–lymphocyte ratio in acute stroke patients. We defined poor function outcomes according to the modified Rankin Scale ≥ 3 or Glasgow Outcome Scale< 3.Thirteen studies with 4443 patients were included in our analysis, including 7 ischemic and 6 hemorrhagic stroke studies. The pooled odds ratios for poor functional outcome at 3 months with a higher neutrophil–lymphocyte ratio in acute ischemic and hemorrhagic patients were 1.689 (95% CI = 1.184–2.409, p < 0.001) and 1.125 (95% CI = 1.022–1.239, p < 0.001), respectively, and the overall pooled odds ratio for poor functional outcome following stroke was 1.257 (95% CI = 1.146–1.379, p < 0.001). At the same time, the overall combined odds ratio for death at 3 months was 1.632 (95% CI = 1.155–2.306, p < 0.001).The neutrophil–lymphocyte ratio, an easily calculated marker, plays a predictive role in the short-term outcomes of adult patients (mean age ≥ 50 years) following acute ischemic and hemorrhagic stroke.

Abstract
OBJECTIVE The neutrophil-to-lymphocyte ratio (NLR) has been investigated as an independent predictive marker for clinical outcomes in vascular diseases. This study aimed to investigate the peri-interventional behavior of the NLR in patients with ruptured and unruptured intracranial aneurysms (IAs). METHODS A total of 117 patients with IAs, who were treated at our department and had available complete data, were retrospectively identified during a 10-year period. Routine laboratory parameters, including the neutrophil and lymphocytes counts, were evaluated before and after treatment. RESULTS The baseline NLR showed significant differences between patients with ruptured and unruptured IAs (6.3 vs. 1.8; P < 0.001). In patients with ruptured IAs, the baseline NLR decreased significantly during the follow-up visits, whereas in unruptured IAs, the NLR remained low. Furthermore, higher baseline NLR values could also be observed in patients with ruptured IAs and fatal outcome than in surviving patients (8.0 vs. 5.4; P = 0.220). In patients with poor functional outcome, defined as modified Rankin score ≥3, the NLR was significantly higher before treatment (P = 0.047), at day 10 (P = 0.025), and 1 month after treatment (P = 0.001). CONCLUSIONS The peri-interventional NLR was significantly different between patients with ruptured and unruptured IAs. In patients with ruptured IAs, elevated baseline NLR levels were associated with poor postoperative functional outcomes and decreased postoperatively, implying the potential prognostic value of NLR in patients with IAs.

World Neurosurg 2019; 134:e631-e635. [PMID: 31682990 DOI: 10.1016/j.wneu.2019.10.154] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2019] [Revised: 10/23/2019] [Accepted: 10/24/2019] [Indexed: 02/05/2023]
Abstract
OBJECTIVE To evaluate whether the postoperative neutrophil-to-lymphocyte ratio (NLR) is a prognostic marker for patients with intracerebral hemorrhage (ICH) undergoing surgical hematoma evacuation. METHODS This retrospective cohort study was conducted to identify patients with ICH who underwent hematoma evacuation between January 2013 and December 2018. Data on demographics, clinical features, laboratory tests (admission and postoperative), and imaging information were collected. The associations between variables and 30-day mortality were assessed by multivariable logistic regression analysis. The predictive power of independent predictors was evaluated by receiver operating characteristic (ROC) curve analysis. RESULTS A total of 380 patients were included. Multivariable analysis identified admission Glasgow Coma Scale score (odds ratio [OR], 0.61; 95% confidence interval [CI], 0.53-0.70; P < 0.001) and initial hematoma volume (OR, 1.01; 95% CI, 1.01-1.02; P = 0.022) were independently associated with 30-day mortality. With regard to laboratory biomarkers, postoperative NLR (OR, 1.04; 95% CI, 1.01-1.08; P = 0.014) was independently correlated with 30-day death, but admission NLR (OR, 1.00; 95% CI, 0.97-1.03; P = 0.944) was not. The best predictive cutoff point of 12.97 for postoperative NLR (area under the ROC curve, 0.606; P = 0.006) for predicting 30-day mortality was determined by ROC analysis. CONCLUSIONS In patients with ICH undergoing hematoma evacuation, admission Glasgow Coma Scale score, initial hematoma volume, and postoperative NLR were independently associated with 30-day mortality. Postoperative NLR may be a prognostic marker in surgical ICH patients, and future studies are needed to confirm this finding.

Clinical Value of Neutrophil-to-Lymphocyte Ratio in Primary Intraventricular Hemorrhage. World Neurosurg 2019; 127:e1051-e1056. [PMID: 30980971 DOI: 10.1016/j.wneu.2019.04.040] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2018] [Revised: 04/03/2019] [Accepted: 04/04/2019] [Indexed: 02/05/2023]
Abstract
OBJECTIVES The neutrophil-to-lymphocyte ratio (NLR) reflects the balance between innate and adaptive inflammatory responses. This study intended to evaluate parameters associated with admission high NLR and its impact on clinical outcome in patients with primary intraventricular hemorrhage (PIVH). METHODS This study retrospectively analyzed consecutive patients with PIVH without a history of head trauma or parenchymal/subarachnoid hemorrhage on computed tomography scan between 2010 and 2016 in a single center. Clinical outcomes at discharge and 90 days were assessed with the modified Rankin Score (mRS) and dichotomized as good (mRS 0-2) and poor (mRS 3-6) outcomes. Associations were estimated using multivariable logistic regression. RESULTS We had 171 patients with PIVH included in the present study. There were 94 male (55.0%) and 77 female (45.0%) patients, with an average age of 46.1 ± 17.2 years. Multivariable logistic analyses revealed independent associations of high NLR (≥8.25) with higher Graeb score, Moyamoya disease, higher admission blood glucose level, and lower platelet count. The patients with high NLR had poorer outcome at discharge and 90 days. After adjustment, the patients with high NLR tended to be associated with poor outcome both at discharge and 90 days. In addition, NLR exhibited a superior predictive power of pneumonia in PIVH than absolute neutrophil count and white blood cell count. CONCLUSIONS NLR tended to be associated with 90-day clinical outcomes of patients with PIVH and exhibited independent predictive power for pneumonia in PIVH.

J Neurol Sci 2018; 396:133-139. [PMID: 30471632 DOI: 10.1016/j.jns.2018.11.022] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2018] [Revised: 10/13/2018] [Accepted: 11/16/2018] [Indexed: 02/05/2023]
Abstract
OBJECTIVES It is well known that early hematoma expansion is associated with short-term prognosis of patients with intracranial hemorrhage (ICH). And spot sign is recognized as a reliable computed tomography angiography (CTA) predictor for early hematoma expansion. Recently, island sign is also reported as a novel computed tomography (CT) predictor for early hematoma growth. Here, we compared the predictive abilities of these two signs for short-term outcomes of ICH patients. PATIENTS AND METHODS All the ICH patients were retrospectively identified. Clinical characteristics and radiological parameters were obtained from electronic medical records. Hematoma expansion, spot sign and island sign were assessed by two senior neurologists according to the initial and follow-up CT scans. 3-months prognoses were estimated according to Glasgow outcome scale (GOS). Multivariate logistic regression analyses were employed to explore the associations of short-term prognosis on island sign, spot sign and other clinical variables. RESULTS There were 283 ICH patients included. 113 of them presented with early hematoma expansions. 66 of them exhibited island sign, while spot sign occurred in 85 patients. Univariate analyses demonstrated that GCS score at admission (OR: 0.464, 95%CI: 0.395-0.547), hematoma volume (OR:1.062, 95%CI: 1.041-1.083), interventricular extension(OR:9.528, 95%CI: 3.915-23.187), island sign (OR: 4.595, 95%CI: 2.404-8.784) and spot sign (OR: 4.052, 95%CI: 2.297-7.147) were correlated with 3-months morbidity. Moreover, multivariate logistic regression analyses further revealed that both spot sign (OR: 3.413, 95%CI: 1.570-7.422) and island sign (OR: 7.564, 95%CI: 2.969-19.273) were strongly associated with 3-months poor outcome and have comparable predictive values (AUC: 0.636 vs. 0.622, P = .58). However, spot sign exhibited a superior predictive ability for 3-months mortality compared to island sign (OR: 2.713, 95%CI: 1.570-4.217 vs. OR: 2.362, 95%CI: 1.238-3.899, AUC: 0.700 vs. 0.603, P < .01). CONCLUSIONS Island sign is not just a convenient and reliable predictor for short-term prognosis of ICH patients, but also could be used as an indicator for accurate diagnosis and aggressive treatment.
