Abstract
BACKGROUND Neutrophil to lymphocyte ratio (NLR) has been considered a prognostic biomarker of mortality and other major cardiac events. This study investigates NLR's efficacy in predicting in-hospital and long-term outcomes in patients with ST-segment elevated myocardial infarction (STEMI) undergoing percutaneous coronary intervention (PCI). METHODS Electronic databases (PUBMED, Cochrane CENTRAL, ERIC, Embase, Ovid, and Google Scholar) were searched till June 2022 to identify studies having STEMI patients who underwent PCI. Risk ratios and mean differences (MDs), along with their corresponding 95% confidence intervals (Cis) and standard deviations (SDs), were pooled using a random-effect model. This meta-analysis has been registered on Prospero (ID: CRD42022344072). RESULTS A total of 35 studies with 28,756 patients were included. Pooled estimates revealed an increased incidence of primary outcomes; in-hospital all-cause mortality (RR = 3.52; 95% CI = 2.93-4.24), long-term all-cause mortality (HR = 1.07; 95% CI = 1.00-1.14), (RR = 3.32; 95% CI = 2.57-4.30); in-hospital cardiovascular mortality (RR = 2.66; 95% CI = 2.04-3.48), long-term cardiovascular mortality (RR = 6.67; 95% CI = 4.06-10.95); in-hospital major adverse cardiovascular events (MACE) (RR = 1.31; 95% CI = 1.17-1.46), long-term MACE (RR = 2.92; 95% CI = 2.16-3.94); length of hospital stay (WMD = 0.60 days; 95% CI = 0.40-0.79) in patients with high NLR compared to those with a low NLR. CONCLUSION NLR might be a valuable tool for prognostication (in-hospital) and stratification of patients with STEMI who underwent PCI.

Abstract
Myocardial infarction (MI), a leading cause of morbidity and mortality globally, is characterized by an underlying inflammatory process driven by atherosclerosis. The neutrophil-to-lymphocyte ratio (NLR), a readily available and cost-effective marker of systemic inflammation, has emerged as a potential predictor of adverse outcomes in patients with MI. This meta-analysis aimed to evaluate the association between elevated NLR and the risk of major adverse cardiovascular events (MACE) and all-cause mortality in patients with MI. A comprehensive literature search was conducted across multiple databases, including Embase, Web of Science, PubMed, and OVID Medicine, to identify relevant studies published from January 1, 2011, onward. Studies reporting the effect of NLR values on MACE and mortality in adult patients with MI, including both ST-elevation (STEMI) and non-ST-elevation (NSTEMI) subtypes, were included. Data extraction and quality assessment were performed independently by multiple authors. The meta-analysis included 37 studies, comprising a total of 18 studies evaluating the risk of MACE and 30 studies assessing all-cause mortality. The pooled analysis revealed a significantly increased risk of MACE (odds ratio [OR] 1.86, 95% confidence interval [CI] 1.53-2.28, P < 0.01) and all-cause mortality (OR 2.29, 95% CI 1.94-2.70, P < 0.01) in patients with elevated NLR compared to those without elevated NLR. Subgroup analyses stratified by follow-up duration and study design further supported the consistent association between elevated NLR and adverse outcomes. In conclusion, this meta-analysis demonstrates a significant association between elevated NLR and an increased risk of MACE and all-cause mortality in patients with MI. These findings highlight the potential clinical utility of NLR as a prognostic marker and underscore the importance of further research to validate its predictive value and establish optimal cutoff values for risk stratification in this patient population.

Abstract
BACKGROUND The neutrophil-to-lymphocyte ratio (NLR) is the ratio between neutrophil and lymphocyte counts measured in peripheral blood. NLR is easily calculable based on a routine blood test available worldwide and may reflect systemic inflammation. However, the relationship between NLR and clinical outcomes in atrial fibrillation (AF) patients is not well-described. METHODS We calculated NLR at baseline in ENGAGE AF-TIMI 48, a randomized trial comparing edoxaban versus warfarin in patients with AF followed for 2.8 years (median). The association of baseline NLR with major bleeding events, major adverse cardiac events (MACE), cardiovascular death, stroke/systemic embolism, and all-cause mortality were calculated. RESULTS The median baseline NLR in 19,697 patients was 2.53 (interquartile range 1.89-3.41). NLR was associated with major bleeding events (HR 1.60; 95% CI 1.41-1.80), stroke/systemic embolism (HR 1.25; 95% CI, 1.09-1.44), MI (HR 1.73; 95% CI 1.41-2.12), MACE (HR 1.70; 95% CI 1.56-1.84), CV (HR 1.93; 95% CI 1.74-2.13) and all-cause mortality (HR 2.00; 95% CI 1.83-2.18). The relationships between NLR and outcomes remained significant after adjustment for risk factors. Edoxaban consistently reduced major bleeding. MACE, and CV death across NLR groups vs. warfarin. CONCLUSIONS NLR represents a widely available, simple, arithmetic calculation that could be immediately and automatically reported during a white blood cell differential measurement to identify patients with AF at increased risk of bleeding, CV events, and mortality.

Abstract
BACKGROUND Kawasaki disease is a vasculitis that can lead to cardiac complications, including coronary artery disease and cardiogenic shock. Various scoring systems have been developed to determine those that will be refractory to routine intravenous immunoglobulin therapy or develop coronary artery disease. The objective of this study was to determine if the neutrophil-lymphocyte ratio could predict refractory disease and coronary artery lesions in patients with Kawasaki disease. METHODS A systematic review of the literature was performed to identify manuscripts describing comparisons of neutrophil-lymphocyte ratio between those who had refractory disease and those who did not, and between those who developed coronary artery lesions and those who did not. Mean difference was compared between groups. Areas under the curve were utilised to determine the pooled area under the curve. RESULTS 12 studies with 5593 patients were included in the final analyses of neutrophil-lymphocyte ratio for the prediction of refractory disease. Neutrophil-lymphocyte ratio before therapy was higher in refractory disease with a mean difference of 2.55 (p < 0.01) and pooled area under the curve of 0.724. Neutrophil-lymphocyte ratio after therapy was higher in refractory disease with a mean difference of 1.42 (p < 0.01) and pooled area under the curve for of 0.803. Five studies with 1690 patients were included in the final analyses of neutrophil-lymphocyte ratio for the prediction of coronary artery lesions. Neutrophil-lymphocyte ratio before therapy was higher in coronary artery lesions with a mean difference of 0.65 (p < 0.01). CONCLUSION The use of neutrophil-lymphocyte ratio may help physicians in the identification of patients at risk of refractory disease and coronary artery lesions in patients with Kawasaki disease.

Relationships between Easily Available Biomarkers and Non-Dipper Blood Pressure Pattern in Patients with Stable Coronary Artery Disease. Life (Basel) 2023; 13:life13030640. [PMID: 36983796 PMCID: PMC10057299 DOI: 10.3390/life13030640] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2022] [Revised: 02/09/2023] [Accepted: 02/23/2023] [Indexed: 03/03/2023] Open
Abstract
Introduction. Chronic inflammation plays an essential role in the pathophysiology of both arterial hypertension (HTN) and coronary artery disease (CAD), and is more pronounced in individuals with a non-dipper circadian blood pressure (BP) pattern. A non-dipping BP pattern is in turn is associated with increased cardiovascular morbi-mortality, and a higher risk of atherosclerotic events. Neutrophil to lymphocyte ratio (NLR), monocyte to lymphocyte ratio (MLR) and platelet to lymphocyte ratio (PLR) are readily available predictors of systemic inflammation and cardiovascular risk. The purpose of our study is to evaluate whether NLR, MLR and PLR can be used as cost-effective predictors of a non-dipping blood pressure pattern in hypertensive patients with stable CAD. Materials and Methods: We performed a cross-sectional retrospective analysis that included 80 patients with hypertension and stable CAD (mean age 55.51 ± 11.83 years, 71.3% male) referred to a cardiovascular rehabilitation center. All patients underwent clinical examination, 24 h ambulatory blood pressure monitoring (ABPM) and standard blood analysis. Results: Baseline demographic characteristics were similar in both groups. Patients with non-dipper pattern had significantly higher NLR (median = 2, IR (2–3), p < 0.001), MLR (median = 0.31, IR (0.23–0.39), p < 0.001) and PLR (median = 175, IR (144–215), p < 0.001) compared to dippers. Conclusion: Our results suggest that MLR and PLR are inexpensive and easily accessible biomarkers that predict a non-dipping pattern in hypertensive patients with stable CAD.

Abstract
Background Thrombosis and inflammation are crucial elements in the pathogenesis of cardiovascular disease. Hematological parameters elucidate information involving the inflammatory and blood coagulation processes. Objectives The current study explored the association of hematological parameters with EOCAD to identify specific risk factors. Design A single-center retrospective case-control study was conducted with 1693 coronary artery disease patients and 1693 controls. Methods Hematological parameters were examined through an automated analyzer. Results The basophil percentage was significantly reduced in EOCAD (0.43 ± 0.26, p < 0.001) and MI (0.33 ± 0.24, p < 0.001) groups compared with controls (0.54 ± 0.28). The eosinophil percentage was also significantly lower in EOCAD (2.21 ± 1.71, p < 0.001) and MI (1.71 ± 2.44, p < 0.001) groups compared with controls (2.41 ± 1.75). The lymphocyte percentage in patients of EOCAD and MI and controls was 31.65 ± 7.93, 25.48 ± 9.43, and 34.82 ± 7.28, respectively. A significant difference was observed among the groups (p < 0.001). Except for the mean corpuscular hemoglobin (MCH), other red blood cell (RBC) parameters significantly differed between EOCAD patients and controls. The red blood cell distribution width (RDW), hematocrit (HCT), RBC count, mean corpuscular hemoglobin concentration (MCHC), mean corpuscular volume (MCV), and hemoglobin level were associated with EOCAD prevalence after adjusting for baseline differences. Platelet volume distribution width (PDW) also correlated with EOCAD prevalence (ORadjust = 1.087, 95% CI: 1.044-1.131). Conclusions Hematological parameters are closely associated with EOCAD. Moreover, leukocyte parameters correlated with the presence and severity of the disease. In addition, erythrocyte parameters were associated with the disease presence but not with the disease severity. Among the platelet parameters, only PDW was related to the disease presence.

Abstract
Purpose The prognostic value of neutrophil-to-lymphocyte ratio (NLR) has been studied for colorectal cancer. Elderly patients in general tend to have comorbidities and decreased organ function that potentially influence the NLR score. The aim of this study was to investigate the relationship between NLR and cancer-specific survival in elderly patients with colon cancer, using a propensity score-matched analysis. Patients and Methods A total of 203 patients aged over 75 years who underwent curative resection for colon cancer and were diagnosed pathologically with stage II/III disease were eligible for entry to the study. Patients were divided into two groups according to NLR score: NLR-High (NLR≥4.5) group (NLR-H, n=60) and NLR-Low (NLR<4.5) group (NLR-L, n=143). After propensity score matching, 57 patients in each group were matched. Results Before matching, Charlson comorbidity index was significantly higher in the NLR-H group (4 vs 2, p<0.001). After matching, all factors were similar between the groups. The median follow-up period was 43 months (range, 1-160 months). Five-year relapse-free-survival (69.8% vs 87.3%, p=0.030) and cancer-specific survival (83.0% vs 96.0%, p=0.042) were significantly lower in the NLR-H group. Conclusion NLR appears to be a cancer-specific prognostic marker in elderly patients with colon cancer.

Abstract
Abstract
Background: Low-grade chronic inflammation is an important feature of chronic kidney disease (CKD).
Aim: To determine the values of C-reactive protein (CRP), neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) in patients with different stages of CKD and to examine how they change depending on the progression of renal damage.
Materials and methods: A cross-sectional descriptive comparative study included 157 subjects at different stages of CKD which was assessed based on glomerular filtration rate (GFR) calculated according to the MDRD equation. CRP was analyzed by an immunoturbidimetric method. NLR and PLR were calculated by a mathematical calculation after a blood count was performed.
Results: The present study showed an increase in serum creatinine, CRP, and NLR values with progression of renal failure. There was a statistically significant difference in the creatinine and CRP concentrations between groups with different stages of CKD (p <0.001 for all comparisons). A significant positive correlation was found between NLR and CRP, while negative, significant correlations were observed between NLR and eGFR as well as between PLR and eGFR. There was a slight increase in PLR value with the progression of renal impairment, but the correlation between PLR and CRP was not significant.
Conclusion: These results suggest that NLR, together with CRP, may serve as an indicator of systemic low-grade inflammation progression in patients with CKD. Larger prospective studies are required to observe the possibility of using NLR as a surrogate marker for CRP in patients with CKD.

Abstract
Objectives Inflammation is a hallmark of the initial development and progression of aortic dissection. This study aimed to investigate the value of preoperative inflammatory biomarkers in predicting aorta-related adverse events (AAEs) after thoracic endovascular aortic repair (TEVAR) for type B aortic dissection. Methods We included all patients who underwent TEVAR for type B aortic dissection between November 2016 and November 2020 in this single-center, retrospective cohort study. Patients were divided into two groups: the AAEs group (n = 75) and the non-AAEs group (n = 126). Preoperative inflammatory biomarkers were recorded, including neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), platelet-to-lymphocyte ratio (PLR), systemic immune inflammation index (SII), and systemic inflammatory response index (SIRI). Patients were followed-up for the development of AAEs. Prediction accuracy of inflammatory biomarkers for AAEs were evaluated using the area under the receiver operating characteristic curves. Results This study included 201 patients, of whom 80.0% were men, with a mean age of 59.1 ± 12.5 years. A total of 75 patients developed AAEs after TEVAR. The AUCs of NLR, MLR, PLR, SII, and SIRI for AAEs were.746,.782,.534,.625 and.807, respectively. Age and SIRI were independent risk factors for the AAEs after TEVAR (HR 3.264, p <.001; HR 4.281, p <.001, respectively). Survival analysis revealed significantly lower AAE-free status in patients with preoperative SIRI > = 4 (p <.001). Conclusion Increased preoperative SIRI and age are independent risk factors for AAEs after TEVAR in type B aortic dissection.

Abstract
Background NLR is a systemic inflammatory marker that have been associated with overall survival in patients with some rapidly progressive disease. There are few data about the diagnostic and predictive value of NLR in autoimmune diseases, and it has not been described in anti-MDA5 positive DM. We try to correlate neutrophil-to-lymphocyte ratio (NLR) with fatality from dermatomyositis in anti-MDA5 positive patients. Method A retrospective study in which 195 patients were enrolled was conducted. Clinical and laboratory information was collated and ratios of neutrophil to lymphocyte counts (NLR) calculated. The primary end point was all-cause death. Result Of the 195 patients studied, all had interstitial lung disease, including 140 survivors and 55 non-survivors. An optimal NLR cut-off value of 4.86 for mortality prediction was identified. The NLR of non-survivors was significantly higher than that of survivors (p < 0.001). Plasma levels of lactate dehydrogenase (LDH) and C-reactive protein were significantly increased when NLR was greater than 4.86. Results of multivariate analysis established that NLR > 4.86 was an independent predictor of mortality (HR: 2.52; 95%CI: 1.33–4.78; p = 0.005). Abstinence from smoking (HR: 2.66; 95%CI: 1.33–4.78; p = 0.003), emergence of rapidly progressive interstitial lung disease (RPILD; HR: 4.38; 95%CI: 2.37–8.08; p < 0.001), low plasma LDH (HR: 3.82; 95%CI: 2.06–7.11; p < 0.001) and presentation with dyspnea (HR: 2.17; 95%CI: 1.22–3.86; p = 0.009) were all protective factors predictive of survival. Conclusion NLR is a cost-effective and widely accessible biomarker with utility for risk stratification in patients with anti-MDA5 + dermatomyositis.

Value of the Neutrophil to Lymphocyte Ratio and Platelet to Lymphocyte Ratio in Predicting CPET Performance in Patients with Stable CAD and Recent Elective PCI. MEDICINA (KAUNAS, LITHUANIA) 2022; 58:medicina58060814. [PMID: 35744077 PMCID: PMC9229341 DOI: 10.3390/medicina58060814] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/23/2022] [Revised: 06/05/2022] [Accepted: 06/14/2022] [Indexed: 02/07/2023]
Abstract
Background and Objectives: Functional capacity (FC) assessed via cardiopulmonary exercise testing (CPET) is a novel, independent prognostic marker for patients with coronary artery disease (CAD). Neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) are two readily available predictors of systemic inflammation and cardiovascular event risk, which could be used as cost-effective predictors of poor FC. The purpose of this study was to evaluate the utility of NLR and PLR in predicting poor FC in patients with CAD and recent elective percutaneous coronary intervention (PCI). Materials and Methods: Our cross-sectional retrospective analysis included 80 patients with stable CAD and recent elective PCI (mean age 55.51 ± 11.83 years, 71.3% male) who were referred to a cardiovascular rehabilitation center from January 2020 to June 2021. All patients underwent clinical examination, cardiopulmonary exercise testing on a cycle ergometer, transthoracic echocardiography and standard blood analysis. Results: Patients were classified according to percent predicted oxygen uptake (% VO2 max) in two groups—poor FC (≤70%, n = 35) and preserved FC (>70%, n = 45). There was no significant difference between groups regarding age, gender ratio, presence of associated comorbidities, left ventricular ejection fraction and NLR. PLR was higher in patients with poor FC (169.8 ± 59.3 vs. 137.4 ± 35.9, p = 0.003). A PLR cut-off point of 139 had 74% sensitivity and 60% specificity in predicting poor FC. After multivariate analysis, PLR remained a significant predictor of poor functional status. Conclusions: Although CPET is the gold standard test for assessing FC prior to cardiovascular rehabilitation, its availability remains limited. PLR, a cheap and simple test, could predict poor FC in patients with stable CAD and recent elective PCI and help prioritize referral for cardiovascular rehabilitation in high-risk patients.

Abstract
Electrical storm (ES) is a life-threatening condition that may lead to recurrent arrhythmias, need for ventricular mechanical support, and death. The study aimed to assess the burden of arrhythmia recurrence and in-hospital outcomes of patients admitted for ES in a large urban hospital. We performed a retrospective analysis of patients admitted with ventricular arrhythmias from January 2018 to June 2021 and identified 61 patients with ES, defined as 3 or more episodes of ventricular tachycardia (VT) or ventricular fibrillation (VF) within 24 hours. We reviewed the in-hospital outcomes and compared outcomes between patients who had no recurrence of VT/VF after the first 24 hours (34 [56%]), those with recurrence of 1 or 2 episodes of VT/VF within a 24-hour period (15 [24%]), and patients with 3 or more recurrent VT/VF events consistent with recurrent ES after the first 24 hours (12 [20%]). Patients with recurrent ES had significantly higher in-hospital mortality as compared with those with recurrent VT/VF not meeting criteria for ES or no recurrences of VT/VF (3 [25%] vs 0 [0%] vs 0 [0%]; p = 0.002). Moreover, patients with recurrent ES also had higher rates of the combined end points of ventricular mechanical support and death (7 [58%] vs 1 [6%] vs 1 [3%], p <0.001), invasive mechanical ventilation and death (10 [83%] vs 2 [13%] vs 2 [6%], p <0.001), catheter ablation or death (12 [100%] vs 7 [47%] vs 12 [35%], p <0.001) and heart transplantation and death (3 [25%] vs 2 [13%] vs 0 [0%], p = 0.018). In conclusion, patients admitted with ES have a high risk of in-hospital recurrence, associated with extremely poor outcomes.

Abstract
This study investigated whether the systemic immune-inflammation index (SII) is an independent predictor of contrast-induced nephropathy (CIN) in patients undergoing transcatheter aortic valve replacement (TAVR) for severe aortic stenosis. TAVR patients (n = 130) were included in the study. The patients were divided into 2 groups: those who developed CIN [CIN (+)] and those who did not [CIN (−)]. The SII was calculated as the ratio of the product of the total neutrophil count and the total platelet count to the lymphocyte count. CIN developed in 20 (15.3%) patients after TAVR. White blood cell count (7.66 ± 1.75 vs 6.78 ± 1.71 103/mm3 P = .038), neutrophil count (5.1 (3.9–6.7) vs 4.2 (3.5-5.1) 103/mm3 P = .024), neutrophillymphocyte ratio (4.20 (2.39–7.00) vs 2.75 (2.06-3.88), P = .010) and SII index (1069 (616–1514) vs 598 (426-955), P = .003) were at higher levels in patients with CIN. In addition, the SII index was an independent predictor for the development of CIN. The SII index, which can be easily calculated from a complete blood count, is an independent predictor of CIN in patients undergoing TAVR for severe aortic stenosis.

Abstract
Degree of expression of programmed death-ligand 1 (PD-L1) is related with Immune check point inhibitors (ICIs) response but it needs sufficient tumor tissue. There is unmet need for easily accessible and prognostic peripheral blood (PB) biomarkers. We investigated the application of serum peripheral lymphocyte count (PLC) as a predictive PB biomarker for ICI response in patients with NSCLC. We conducted a retrospective study and reviewed the patients with NSCLC who were treated with ICIs from April 1, 2016, to March 31, 2019. The PLC before and after 1 month of immunotherapy was collected. We evaluated the association between PLC and progression-free survival (PFS), overall survival (OS) and adverse events. A total of 231 patients were treated with ICIs for NSCLC. The median follow-up period was 4.7 months and the disease progressed in 138 patients (59.7%). Compared with the lowest quartile (Q1: the lowest 25%), the highest quartile (Q4: the highest 25%) of post-treatment PLC showed a significantly higher PFS (HR 0.28, 95% CI 0.16-0.52) and OS (HR 0.35, 95% CI 0.19-0.65) in the adjusted model. An association between adverse events and PLC was not observed. We revealed that an increased pre- and post-treatment PLC was associated with favorable PFS and OS with NSCLC patients treated with ICIs. PLC could be a helpful for ICI responses in NSCLC.

Abstract
BACKGROUND Previous studies have assessed the diagnostic accuracy of blood inflammatory markers like neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and C-reactive protein (CRP), and CRP to albumin ratio (CAR) to predict the resistant Kawasaki disease (KD). The aim of the current meta-analysis and systematic review is to compare the prognostic ability of these inflammatory markers to predict the resistance to IVIG in patients with Kawasaki disease. METHODS A systematic search of online academic databases and search engines such as EMBASE, PubMed Central, MEDLINE, Cochrane library, Google Scholar, and ScienceDirect was conducted for papers that report the diagnostic accuracy of inflammatory markers for resistant KD. Meta-analysis was performed using STATA software. RESULTS Twenty-two studies met the inclusion criteria. Pooled sensitivity and specificity of NLR as a predictor of resistant Kawasaki disease was 72% (95% CI: 62%, 80%) and 71% (95% CI: 63%, 78%), with AUC of 0.77 for PLR was 60% (95% CI: 50%, 69%) and 68% (95% CI: 61%, 75%), with area under the curve (AUC) of 0.69. Pooled sensitivity and specificity of CRP was 75% (95% CI: 68%, 81%) and 66% (95% CI: 55%, 76%), respectively, with an AUC value of 0.78. Pooled sensitivity and specificity of combined NLR and PLR was 58% (95% CI: 46%, 69%) and 73% (95% CI: 65%, 79%), respectively, with an AUC value of 0.72. CONCLUSION Our study found that NLR, CRP, PLR, and combined NLR/PLR have a good prognostic value in patients with resistant Kawasaki disease, with moderate to high sensitivity and specificity. More research on the accuracy of these indexes in multiple combinations is needed. SYSTEMATIC REVIEW REGISTRATION [https://www.crd.york.ac.uk/prospero/], identifier [CRD42022322165].

Abstract
Inflammation and lipid signaling are involved in the pathogenesis and progression of coronary artery disease (CAD). We proposed that high-sensitivity C-reactive proteins, as a marker of the pro-inflammatory state, and high-density lipoprotein cholesterol (HDL-C), as an anti-atherosclerosis component, should be integrated into a single novel biomarker. Our work was conducted to discuss and compare the predictive ability of the high-sensitivity C-reactive protein to high-density lipoprotein cholesterol ratio (CHR) with other existing indices, for example, neutrophil high-density lipoprotein ratio (NHR) and neutrophil lymphocyte ratio (NLR), in the severity of CAD patients.Based on the results of coronary angiography, patients were divided into the CAD+ group, CAD- group, and control group. The relationship between various serum markers and the severity of coronary artery disease was examined via Spearman's correlation analysis. Logistic regression analysis was conducted to identify the influencing factors of the coronary artery disease severity.This study included 420 patients. The Gensini score was positively correlated with CHR. Multiple regression analysis revealed that the CHR was significantly associated with CAD. CHR is an independent predictor of CAD. The receiver operating characteristic (ROC) analysis provided a cut-off value of 1.17 for CHR to predict CAD, with a specificity of 86.7%, Yoden index of 0.264, and area under the ROC curve of 0.662 (95% confidence intervals 0.606-0.719, P < 0.001). At the same time, the area under the ROC curve of the NHR was 0.652, and that of the NLR was 0.579. The results of the DeLong test indicated that the area under the ROC curve of the CHR was larger than that of the NLR (P = 0.0306). This suggests that the CHR as a predictor of CAD has better diagnostic performance than the NLR.CHR was not only closely related to the presence and severity of CAD but also an independent predictor of severe CAD.

Abstract
BACKGROUNDS Cardiogenic shock (CS) is the most severe complication after acute myocardial infarction (AMI) with mortality above 50%. Inflammatory response is involved in the pathology of CS and AMI. In this study, we aimed to evaluate the prognostic value of admission neutrophil-lymphocyte ratio (NLR) in patients with CS complicating AMI. METHODS Two hundred and seventeen consecutive patients with CS after AMI were divided into two groups according to the admission NLR cut-off value ≤7.3 and >7.3. The primary outcome was 30-day all-cause mortality and the secondary end-point was the composite events of major adverse cardiovascular events (MACE), including all-cause mortality, ventricular tachycardia/ventricular fibrillation, atrioventricular block, gastrointestinal haemorrhage and non-fatal stroke. Cox proportional hazard models were performed to analyse the association of NLR with the outcome. NLR cut-off value was determined by Youden index. RESULTS Patients with NLR > 7.3 were older and presented with lower lymphocyte count, higher admission heart rate, B-type natriuretic peptide, leucocyte, neutrophil and creatinine (all P < .05). During a period of 30-day follow-up after admission, mortality in patients with NLR > 7.3 was significantly higher than in patients with NLR ≤ 7.3 (73.7% vs. 26.3%, P < .001). The incidence of MACE was also remarkably higher in patients with NLR > 7.3 (87.9% vs. 53.4%, P < .001). After multivariable adjustment, NLR > 7.3 remained an independent predictor for higher risk of 30-day mortality (HR 2.806; 95%CI 1.784, 4.415, P < .001) and MACE (HR 2.545; 95%CI 1.791, 3.617, P < .001). CONCLUSIONS Admission NLR could be used as an important tool for short-term prognostic evaluation in patients with CS complicating AMI and higher NLR is an independent predictor for increased 30-day all-cause mortality and MACE.

Abstract
BACKGROUND The slow-flow/no-reflow phenomenon and impaired ST segment resolution (STR) following primary percutaneous coronary intervention (PCI) in ST-elevation myocardial infarction (STEMI) predict unfavorable prognosis and are characterized by obstruction of the coronary microvascular. Several predictors of slow-flow/no-reflow have been revealed, but few studies have investigated predictors of slow-flow/no-reflow and STR exclusively in acute myocardial infarction patients with initial Thrombolysis in Myocardial Infarction (TIMI) Grade 0.Methods and Results:In all, 279 STEMI patients with initial TIMI Grade 0 were enrolled in the study. Slow-flow/no-reflow was defined as TIMI Grade <3 by angiography after PCI, and impaired STR was defined as STR <50% on an electrocardiogram after PCI. Slow-flow/no-reflow was observed in 31 patients. In multivariate analysis, estimated glomerular filtration rate (eGFR; odds ratio [OR] 0.97; P=0.007), a history of cerebrovascular disease (OR 4.65, P=0.007), time to recanalization ≥4 h (OR 2.76, P=0.023), and systolic blood pressure ≤90 mmHg (OR 3.45, P=0.046) were independent predictors of slow-flow/no-reflow. Impaired STR was observed in 102 of 248 patients with TIMI Grade 3. In multivariate analysis, eGFR (OR 0.94, P<0.001) and occlusion of the left anterior descending artery (OR 4.48, P<0.001) were independent predictors of impaired STR; eGFR was the only independent predictor of both slow-flow/no-reflow and impaired STR. CONCLUSIONS Renal dysfunction may be related to coronary microvascular dysfunction and obstruction.

Abstract
Background Glutathione is a water‐soluble tripeptide with a potent oxidant scavenging activity. We hypothesized that glutathione administration immediately before and after primary angioplasty (primary percutaneous coronary intervention) could be effective in modulating immune cell activation, thereby preventing infarct expansion. Methods and Results One hundred consecutive patients with ST‐segment–elevation myocardial infarction, scheduled to undergo primary percutaneous coronary intervention were randomly assigned before the intervention to receive an infusion of glutathione (2500 mg/25 mL over 10 minutes), followed by drug administration at the same doses at 24, 48, and 72 hours elapsing time or placebo. Total leukocytes, NOX2 (nicotinamide adenine dinucleotide phosphate oxidase 2) activation, NO bioavailability, cTpT (serum cardiac troponin T), hsCRP (high‐sensitivity C‐reactive protein), and TNF‐α (tumor necrosis factor α) levels were measured. Left ventricular size and function were assessed within 120 minutes, 5 days, and 6 months from percutaneous coronary intervention. Following reperfusion, a significant reduction of neutrophil to lymphocyte ratio (P<0.0001), hsCRP generation (P<0.0001), NOX2 activation (P<0.0001), TNF‐α levels (P<0.001), and cTpT release (P<0.0001) were found in the glutathione group compared with placebo. In treated patients, blunted inflammatory response was linked to better left ventricular size and function at follow‐up (r=0.78, P<0.005). Conclusions Early and prolonged glutathione infusion seems able to protect vital myocardial components and endothelial cell function against harmful pro‐oxidant and inflammatory environments, thus preventing maladaptive cardiac repair and left ventricular adverse remodeling.

Abstract
OBJECTIVE Inflammation plays a critical role in atherosclerosis. This study examines the effects of ticagrelor and clopidogrel on inflammatory parameters, obtained from complete blood count (CBC) and biochemical measurements, in patients with acute coronary syndrome. METHODS AND RESULTS One hundred acute coronary syndrome (ACS) patients were included in the study and grouped according to clopidogrel (n = 50) or ticagrelor (n = 50) usage as an anti-aggregant (with acetylsalicylic acid). All patients underwent percutaneous coronary intervention. On admission, at third- and sixth-month after ACS, white blood cell (WBC) count, neutrophil-to-lymphocyte ratio (NLR), monocyte-to-high-density lipoprotein ratio (MHR), platelet-to-lymphocyte ratio (PLR), and systemic immune-inflammation index (SII) were calculated from the CBC and biochemical measurements. NLR, PLR, and SII were significantly lower in the ticagrelor group (p < 0.001, at 3rd and 6th month). Also, MHR was lower in the ticagrelor group (p < 0.05). Conversely, WBC count was higher in the ticagrelor group (p < 0.001). CONCLUSIONS NLR, MHR, PLR, and SII levels were lower in ACS patients treating with ticagrelor. Ticagrelor may improve these inflammatory parameters in percutaneous coronary intervention (PCI)-treated ACS patients compared to clopidogrel.

Abstract
BACKGROUND The neutrophil-to-lymphocyte ratio (NLR) has been proven to be a reliable inflammatory marker. A recent study reported that elevated NLR is associated with adverse cardiovascular events in patients with ST-segment elevation myocardial infarction (STEMI). We investigated whether NLR at emergency room (ER) is associated with mechanical complications of STEMI undergoing primary percutaneous coronary intervention (PCI). METHODS A total of 744 patients with STEMI who underwent successful primary PCI from 2009 to 2018 were enrolled in this study. Total and differential leukocyte counts were measured at ER. The NLR was calculated as the ratio of neutrophil count to lymphocyte count. Patients were divided into tertiles according to NLR. Mechanical complications of STEMI were defined by STEMI combined with sudden cardiac arrest, stent thrombosis, pericardial effusion, post myocardial infarction (MI) pericarditis, and post MI ventricular septal rupture, free-wall rupture, left ventricular thrombus, and acute mitral regurgitation during hospitalization. RESULTS Patients in the high NLR group (> 4.90) had higher risk of mechanical complications of STEMI (P = 0.001) compared with those in the low and intermediate groups (13% vs. 13% vs. 23%). On multivariable analysis, NLR remained an independent predictor for mechanical complications of STEMI (RR = 1.947, 95% CI = 1.136-3.339, P = 0.015) along with symptom-to balloon time (P = 0.002) and left ventricular dysfunction (P < 0.001). CONCLUSION NLR at ER is an independent predictor of mechanical complications of STEMI undergoing primary PCI. STEMI patients with high NLR are at increased risk for complications during hospitalization, therefore, needs more intensive treatment after PCI.

Abstract
Objective This study aimed to investigate the predictive value of inflammatory cells in peripheral blood on the prognosis of patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI). Methods Patients (n=1558) were consecutively enrolled and the median follow-up was 1142 days. Patients were divided into the major adverse cardiac events (MACE) 1 group (n=63) (all-cause mortality [n=58] and rehospitalization for severe heart failure [n=5], no MACE1 group (n=1495), MACE2 group (n=38) (cardiac mortality [n=33] and rehospitalization for severe heart failure [n=5]), and no MACE2 group (n=1520). The neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), and platelet-to-lymphocyte ratio (PLR) were analyzed. Results The NLR, MLR, and PLR were higher in the MACE groups than in the no MACE groups. Different subsets of inflammatory cells had similar diagnostic values for MACE. Kaplan–Meier curves showed that the survival time gradually decreased with an increase in the degree of risk as determined by the NLR, MLR, and PLR. The risk of MACE was highest in the extremely high-risk group. Conclusion Peripheral blood inflammatory cell subsets can predict MACE in patients with ACS undergoing PCI. These cell subsets could be important laboratory markers for the prognosis and clinical treatment of these patients.

Abstract
BACKGROUND Thoracic aortic endovascular repair (TEVAR) of uncomplicated type B aortic dissection (uTBAD) has favorable long-term outcomes but higher early adverse events compared with the optimal medical treatment. Recently, clinical evidence concerning vascular surgery indicates that elevated preoperative systemic inflammatory response predicts adverse clinical events. The aim of our study was to evaluate the relationship between preoperative neutrophil-to-lymphocyte ratio (NLR) and early outcomes of uTBAD patients undergoing TEVAR. RESULTS 216 patients diagnosed with uTBAD were included in this retrospective study between January 2015 and December 2018. The median (IQR) follow-up period was 21 (15-33) months. An early adverse event was defined as occurring within 2 years after the procedure. Median patient age was 60 (IQR, 48-68) years and 78.7 % were male. Early adverse events occurred in 24 patients (11.1 %). In the multivariable analysis, preoperative NLR (HR per SD, 1.98; 95 % CI, 1.14-3.44; P = 0.015) was associated with 2-year adverse events. CONCLUSIONS NLR is an independent predictive factor of early adverse events in uTBAD patients undergoing TEVAR.

Abstract
BACKGROUND AND AIMS Despite elevated serum uric acid (eSUA) has been identified as independent risk factor for cardiovascular diseases, its prognostic value in the setting of ST-segment elevation myocardial infarction (STEMI) is still controversial. Although the mechanisms of this possible relationship are unsettled it has been suggested that eSUA could trigger the inflammatory response. This study sought to investigate the association between eSUA with short- and long-term mortality and with inflammatory response in patients with STEMI treated with primary percutaneous coronary intervention (pPCI). METHODS AND RESULTS Blood samples were collected on admission and at 24 and 48 h after pPCI: the inflammatory biomarkers C-reactive protein (CRP), neutrophil count and neutrophil to lymphocytes ratio (NLR) were considered. Baseline eSUA was defined as ≥6.8 mg/dl. Cumulative 30-days and 1-year mortalities were estimated using the Kaplan-Meyer analysis. Multivariable analyses were performed by Cox proportional hazard models. In the 2369 patients with STEMI considered, 30-day mortality was 5.8% among patients with eSUA and 2% among patient with normal SUA level (p < 0.001); 1-year mortality was 8.5% vs 4%, respectively (p < 0.001). At multivariable analyses eSUA was an independent predictor of 30-day mortality (HR 1.196, 95%CI 1.006-1.321, p = 0.042) and 1-year mortality (HR 1.178, 95%CI 1.052-1.320, p = 0.005). eSUA patients presented higher values in on admission CRP (p < 0.001) and in neutrophil count and NLR at 24 h (respectively, p = 0.020 and p < 0.001) and at 48 h (p = 0.018 and p < 0.001) compared to patients with normal SUA levels. CONCLUSIONS Elevated serum uric acid is associated with higher short- and long-term mortality and with a greater inflammatory response after reperfusion in patients with STEMI treated with primary PCI.

Prognostic role of neutrophil-to-lymphocyte ratio in patients with ST-elevation myocardial infarction undergoing to pharmaco-invasive strategy. CARDIOVASCULAR REVASCULARIZATION MEDICINE 2021; 34:99-103. [PMID: 33736961 DOI: 10.1016/j.carrev.2021.01.027] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2020] [Revised: 01/23/2021] [Accepted: 01/26/2021] [Indexed: 12/22/2022]
Abstract
OBJECTIVES We sought to determine the relationship between in-hospital mortality and the neutrophil-to-lymphocyte ratio (NLR) in patients with ST-elevation myocardial infarction (STEMI) undergoing with pharmaco-invasive strategy (PIS). BACKGROUND Increased levels of white blood cells have been associated with adverse clinical outcomes in patients with (STEMI). NLR has recently emerged as a potent and more specific prognostic marker in predicting short- and long-term mortalityin patients undergoing primary percutaneous coronary intervention. This association has never been reported in patients managed with PIS. METHODS Between March 2010 and October 2016, 1860 STEMI patients managed with PIS were consecutively included in a dedicated database. The study population was divided into tertiles based on the admission NLR values (lower: <4.0, intermediate: 4.0 to <7.3, and upper: ≥7.3). Co-primary endpoints were in-hospital mortality and MACE (death, non-fatal reinfarction or stent thrombosis). RESULTS Patients in the upper NLR tertile had significantly higher in-hospital mortality (9.0% vs. 4.8% versus. 1.8%, p < 0.001) and MACE (11.6% vs. 8.0% versus 2.9%, p < 0.001) than patients with intermediate or low NLR. By multivariable logistic regression analysis, the upper NLR tertile was an independent predictor of MACE (odds radio [OR] 4.19, 95% confidence interval [95% CI] 2.23-7.88, p < 0.001) and in-hospital mortality [OR 3.32, 95% CI 1.19-9.28, p = 0.02]. CONCLUSION High NLR values were independently associated with in-hospital MACE and death in STEMI patients submitted to a PIS. NLR might be a simple and useful risk stratification tool in this high-risk population.

Abstract
INTRODUCTION Myocardial hemorrhage (IMH) and persistent microvascular obstruction (MVO) are associated with impaired myocardial recovery and adverse clinical outcomes in STEMI patients. However, their relationship with circulating inflammatory biomarkers is unclear in human patients. METHODS AND RESULTS Twenty consecutive patients referred for primary percutaneous coronary intervention of first STEMI were included in a prospective study. Blood sampling was performed at admission, 4, 12, 24, 48 hours, 7 and 30 days after reperfusion for inflammatory biomarker (C reactive protein, fibrinogen, interleukin-6 (IL-6) and neutrophils count) assessment. At seven days, cardiovascular magnetic resonance (CMR) was performed for infarct size, MVO and IMH assessment. Median infarct size was 24.6% Interquartile range (IQR) [12.0-43.5] of LV mass and edema was 13.2% IQR [7.7-36.1] of LV mass. IL-6 reached a peak at H24 (5.6 pg/mL interquartile range (IQR) [2.5-17.5]), CRP at H48 (11.7 mg/L IQR [7.1-69.2]), fibrinogen one week after admission (4.4 g/L IQR [3.8-6.7]) and neutrophils at H12 (9.0 G/L IQR [6.5-12.7]). MVO was present in 11 patients (55% of the study population) and hemorrhage in 7 patients (35%). Patients with IMH had significantly higher IL-6, CRP, fibrinogen, and neutrophils levels compared to patients without IMH. Patients with persistent MVO had significantly higher CRP, fibrinogen and neutrophils level compared to patients without MVO, but identical IL-6 kinetics. CONCLUSION In human patients with acute myocardial infarction, intramyocardial hemorrhage appears to have a stronger relationship with inflammatory biomarker release compared to persistent MVO. Attenuating myocardial hemorrhage may be a novel target in future adjunctive STEMI treatments.

Abstract
OBJECTIVES This study aimed to prospectively observe the changes in the neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) before and after percutaneous coronary intervention (PCI) and their impact on the prognosis of patients with acute coronary syndrome (ACS). METHODS Blood samples from 205 patients with ACS were collected at admission and at 24h and 30 days post-PCI to observe changes in the complete blood count. The Cox multivariate regression model was used to analyze the factors influencing major adverse cardiac events (MACE) after PCI in patients with ACS. A receiver operating characteristic (ROC) curve was used to evaluate the predictive value of inflammation indicators for MACE after PCI. RESULTS Following PCI, NLR and PLR first increased postoperatively and then decreased within 30 days after PCI. Cox multivariate regression analysis showed that NLR and PLR at 24h post-PCI and acute ST-segment elevation myocardial infarction were independent influencing factors for the incidence of MACE after PCI. The ROC curve analysis showed that the NLR at 24h post-PCI was a better predictor of the incidence of MACE. The NLR at 24h post-PCI was significantly correlated with the number and length of implanted stents and operation duration. CONCLUSIONS After PCI, patients with ACS had an increased neutrophil proportion and NLR. The NLR at 24h post-PCI was a better predictor of the incidence of postoperative MACE.

Abstract
OBJECTIVE Asthma is a heterogeneous disease characterized by chronic progressive airway inflammation. Although the disease has numerous phenotypes, there are no practical biomarkers for distinguishing the phenotypes from one another. To address this challenge, we aimed to reveal whether the systemic immune-inflammation index (SII), an important indicator of systemic inflammation and prognosis in various malignancies and vasculitis, can be used for distinguishing between asthma and NSAID-exacerbated respiratory disease (NERD). METHODS The study enrolled 105 patients (asthma: n = 69; NERD: n = 36). SII was calculated using the formula of neutrophil X platelet/lymphocyte number. Major risk factors, namely ACT score, eosinophil level, total IgE level, N-L ratio (NLR), P-L ratio (PLR), and SII, were evaluated by logistic regression analysis. RESULTS No significant differences were found between the clinical features of the two study groups. Patients with an SII value ≥895.6 had a probability of having NERD with a sensitivity of 30.56%, whereas those with a lower SII had a probability of having asthma with a sensitivity of 92.65%. In the logistic regression analysis, no risk factor was determined for identifying asthma or NERD. The N-L ratio was found to be the risk factor affecting categorized SII (OR = 264.2, 95% CI 9.9-7046.5, P = 0.001). CONCLUSION This is the first study to evaluate SII as a tool for differentiating asthma phenotypes. The presence of SII below the cutoff value can help exclude the diagnosis of NERD. There is a need for large-scale prospective studies to compare different phenotypes and determine the optimal cutoff value.

Abstract
Introduction Contrast-induced acute nephropathy (CIN) in patients undergoing percutaneous coronary intervention (PCI) in the setting of acute coronary syndromes (ACS) is associated with adverse outcomes, including longer hospitalization and short and long-term mortality. Neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) are inflammatory markers that have been validated separately in prior studies as a predictor of CIN in patients with ACS who undergo a left heart catheterization. Our study aims to further investigate the role of NLR and PLR together as markers for predicting CIN in patients with ACS. Methods A retrospective chart review was performed on a total of 1,577 patients aged 18 - 90 who presented with ACS and underwent PCI between January 2011 to December 2015 at the Florida Hospital Orlando. Cut-off values used for a high PLR and NLR were PLR > 128 and NLR > 2.6. CIN was defined as an increased serum creatinine level by ≥ 0.5 mg/dL, or ≥ 25%, over the baseline value within 72 hours after contrast agent administration. Patients with end-stage renal disease (ESRD) were excluded. Results Of the 1,577 patients included in the study, 213 (13.51%) patients had CIN. On multivariate logistic regression analysis, high NLR showed an independent association with an elevated risk of CIN (OR 2.03, 95% CI: 1.403 - 3.176, P < 0.001). High PLR did not correlate with CIN (OR 0.831, 95% CI: 0.569 - 1.214, P = 0.339). Conclusion Elevated NLR is an independent predictor of CIN in patients with acute myocardial infarction (AMI) and may be used to improve on current risk prediction models.

Abstract
BACKGROUND Neutrophil-to-lymphocyte ratio (NLR) and the platelet-to-lymphocyte ratio (PLR) have been studied so far as prognostic factors of cardiovascular diseases. Their role interplayed with endothelial inflammation has emerged as optimal predictors for major cardiovascular disease events and prognostic factors for post-procedural outcomes. METHODS A review of the current literature was undertaken to investigate the relationship between NLR and PLR with percutaneous, cardiac surgery, and vascular surgery procedures. RESULTS Our findings show that perioperative NLR and PLR levels are significantly correlated with patient morbidity and mortality rates. CONCLUSION These biomarkers have several attractive characteristics, as they are inexpensive and quickly available, and they can contribute to the early identification of patients at high risk for periprocedural adverse events.

Abstract
Objectives Several studies demonstrate the relationship between coronary artery disease and inflammatory parameters. Nevertheless, there is paucity of data regarding the role of high sensitivity (hs)-C-reactive protein (CRP) to albumin ratio (CAR) in patients with ischemia on gated single photon emission tomography (SPECT) myocardial perfusion imaging (MPI). This study was aimed at demonstrating the relationship between CAR and the occurrence of ischemia on gated SPECT MPI. Methods We retrospectively evaluated 2.048 referred patients for gated SPECT MPI from a cardiology outpatient clinic between October 2017 and June 2019. After applying exclusion criteria and measuring serum CRP and albumin levels, we included 126 patients in the study. We then classified subjects into different groups according to the absence or presence of ischemia on gated SPECT MPI. Results According to laboratory findings, hs-CRP and CAR were significantly higher in the ischemia group, while the serum albumin was significantly lower in ischemia group (p<0.05 for each). The independent predictors of presence of ischemia in multivariate analysis were hypertension and CAR (CAR; odds ratio: 5.720, 95% confidence interval: 2.697-12.133, p<0.001). The optimal value of CAR for presence of ischemia was 0.96 with 76% sensitivity and 71% specificity. Conclusion We found CAR values as a predictor for ischemia before MPI.

Abstract
Abstract
Background
Acute pancreatitis is a relatively common acute medical presentation that may progress beyond the pancreas to cause multi-organ failure or death. It is associated with high morbidity and mortality with mortality rates changing little in the past few decades despite advances in intensive care and surgical management. Early evaluation of acute pancreatitis severity is essential to allow the clinician to predict the patient’s clinical course, estimate the prognosis, determine the need for intensive care unit admission, and prevent complications. So, the purpose of our study is to evaluate the prognostic value of the neutrophil to lymphocyte ratio, lactate dehydrogenase enzyme, and proteinuria in patients with acute pancreatitis and its correlation with Ranson’s criteria scoring system as new, rapid, and easy parameters to predict severity of acute pancreatitis.
Results
The mean age of patients in years was 47.97, and the median was 52 with a range of ages between 18 and 87; 38% of the patients included were males, and 61% were females. The mean Ranson’s score was 2.77 ± 1.4, and the median was 3 with a range of 0–6; 44.5% of patients included have low severity, 42.4% have mild severity, and 13.1% of patients have high severity. Neutrophil to lymphocyte ratio both at the time of admission and after 48 h of admission was significantly increasing with an increase in disease severity with a P value of < 0.001 that was statistically significant. Lactate dehydrogenase enzyme at the time of admission was also significantly increasing with diseased severity with a P value of 0.001 that was statistically significant and the same for lactate dehydrogenase enzyme level after 48 h of admission with a P value of 0.002 that was also statistically significant. Proteinuria is positive only in 15.2% of patients and with the same result after 48 h of admission.
Conclusion
The neutrophil to lymphocyte ratio gives a rapid impression of the extent of the inflammatory process, and it can effectively predict severity at the time of admission and even after 48 h of admission and can also differentiate between patients with mild and severe acute pancreatitis in both calcular and non-calcular cause-dependent acute pancreatitis patients. Lactate dehydrogenase can be used to predict severity in calcular cause-dependent acute pancreatitis patients only at the time of admission and after 48 h of admission. Proteinuria in urine analysis on admission and after 48 h does not seem to be a reliable predictor for disease severity in acute pancreatitis.

Abstract
BACKGROUND ST-segment elevation myocardial infarction (STEMI) is the most life-threatening condition of acute coronary syndrome that carries a poor prognosis of in-hospital mortality. Multiple scoring systems have been developed to predict in-hospital mortality and other cardiovascular events. Neutrophil-to-lymphocyte ratio (NLR) is hardly used as a predictor of in-hospital mortality. This study was aimed to determine the predictive value of NLR concerning in-hospital mortality in STEMI patients.
METHODS Literature search and pooled analysis related to studies on MEDLINE/PubMed, EBSCO, Science Direct, Cochrane, and ProQuest were retrieved. Inclusion criteria were met if they were cohort studies, the subjects were STEMI patient, contained pretreatment NLR cut-off, and considered in-hospital mortality, which is defined as cardiac or all-cause mortality. Quality assessment was conducted using Newcastle-Ottawa scale. Review Manager version 5.3 (The Nordic Cochrane Centre, Copenhagen) was used for meta-analysis.
RESULTS We found 12 studies with a total of 7,251 STEMI subjects with median NLR cut-off value of 5.6. Elevated NLR on admission carries a high risk of in-hospital mortality (odds ratio [OR] = 3.00, 95% confidence interval [CI] = 2.46–3.67). A slightly higher risk of all-cause mortality (OR = 2.74, 95% CI = 1.99–3.77) was observed compared with cardiac-related mortality (OR = 3.20, 95% CI = 2.47–4.14). No significant heterogeneity was observed between these studies (p = 0.46, I2 = 0%).
CONCLUSIONS Elevated NLR predicts a higher in-hospital mortality rate of STEMI patients.

Int J Gynaecol Obstet 2020; 150:340-345. [PMID: 32433793 DOI: 10.1002/ijgo.13230] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2019] [Revised: 04/04/2020] [Accepted: 05/15/2020] [Indexed: 12/20/2022]
Abstract
OBJECTIVE To evaluate whether neutrophil-to-lymphocyte ratio (NLR), a well-established inflammatory marker, can be used as an early predictor for small-for-gestational-age (SGA) neonates and other adverse pregnancy outcomes. METHODS A case-control study compared first-trimester hematological biomarkers in pregnancies of patients with and without SGA (n=149, n=151, respectively). Demographic, clinical, and obstetrical characteristics and first-trimester complete blood count were retrieved. Woman with singleton pregnancies who delivered at Soroka University Medical Center between January 2015 and December 2016 were included. Patients with known maternal infections, relevant medications, hematological conditions, and chronic diseases that may alter the blood count, those with multiple pregnancies, and those with congenital or chromosomal abnormalities were excluded. After univariate analysis, a linear regression model was constructed to assess the association between hematological indices and SGA. Receiver operating curves were constructed to evaluate the sensitivity and specificity of NLR. RESULTS First-trimester NLR values of the SGA group were significantly higher compared to controls (3.03 ± 1.68 vs 2.63 ± 1.2, P=0.016). Significantly higher levels of NLR were noted among the severely (<3%) SGA neonates (3.12 ± 1.62 vs 2.62 ± 1.2; P=0.034). CONCLUSION NLR may be an early, clinically useful marker in the prediction of SGA. As blood samples are routinely collected, correct implication of this result may serve as a valuable non-invasive, low-cost, readily available predicting tool.

Abstract
We aimed to investigate the pre-operative predictive role of haematological parameters in patients with testicular torsion. The medical records of patients operated between January 2016 and November 2018 were retrospectively analysed. The demographic characteristics and complete blood count of the patients were recorded. We divided the patients who operated with testicular torsion into two groups: detorsion (Group 1) and orchiectomy (Group 2). A control group (Group 3) was created from healthy volunteers. All haematological parameters and other demographic data were compared between three groups. A total of 144 participants were included; Group 1, Group 2 and Group 3; 61, 27 and 56 respectively. The duration of symptoms and monocyte counts were found statistically significantly higher in patients undergoing orchiectomy than detorsion (p < .01). We found a significant difference in terms of neutrophil, lymphocyte, monocyte counts and neutrophil-lymphocyte ratio between patients with testicular torsion and controls. We also found that the monocytes count and symptom duration differed significantly between the detorsion group and the orchiectomy group. It is obvious that there is contradictory information according to the studies in the literature. We can say that the duration of symptoms and the number of monocytes are predictors of testicular viability.

Abstract
Objective To investigate the predictive value of preoperative neutrophil-lymphocyte ratio (NLR) for long-term major adverse cardiac and cerebrovascular events (MACCE), which have not yet been well described, in patients undergoing coronary artery bypass grafting (CABG). Methods The records of 751 consecutive patients who underwent elective CABG between January 2008 and January 2010 were retrospectively enrolled and stratified according to quartiles of preoperative NLR. At 7.8-year follow-up, MACCE was considered as an endpoint. Results Overall MACCE was 11.6% of all cases. Long-term myocardial infarction, percutaneous coronary intervention, stroke and cardiovascular mortality were found associated with the upper NLR quartile (P<0.001, P<0.001, P=0.005, P<0.001, respectively). In multivariate analysis, NLR on admission remained an independent predictor of long-term MACCE (OR 1.087, 95% CI 1.026-1.151; P=0.004), in all EuroSCORE risk groups (P<0.001; P<0.001; P=0.029). The receiver operating characteristic (ROC) curve analyses revealed an NLR cut-off value of 4.32 predicting MACCE. Conclusion NLR is a useful and readily available predictive marker of long-term MACCE following CABG, independent of the EuroSCORE.

Abstract
Background Neutrophil-to-lymphocyte count ratio (NLCR) has been shown as a feasible parameter associated with outcomes of tumor patients and an accessible predictor of bacteremia. However, only a handful of research shed the light on the association between NLCR and outcomes of septic patients. This study is aimed to evaluate the association between NLCR and all-cause mortality in a population of adult septic patients. Methods We extracted clinical data from Medical Information Mart for Intensive Care (MIMIC)-III V1.4, a free, large-scale, single-center database. NLCR was computed individually. Patients were categorized by quartiles of NLCR. The associations between NLCR quartiles and 28-day all-cause mortality in septic patients were assessed using Cox proportional hazards models and subgroup analyzes. To evaluate the accuracy of NLCR in predicting 28-day mortality of sepsis, receiver operator characteristic curves (ROC), areas under the curve (AUC), and the Youden's J Index were calculated. Other outcomes included 7-day all-cause mortality, mortality in the intensive care units (ICU), in-hospital mortality and length of ICU stay. Results A total of 3,043 eligible patients were included in the study, of which, 760, 759, 766 and 758 patients were fallen in the first quartile (≤5.89), the second quartile (>5.89, ≤10.69), the third quartile (>10.69, ≤20.25) and the fourth quartile (>20.25) of NLCR, respectively. The 7-day mortality (13.4%, 9.9%, 13.6% and 14.2%; P=0.064) showed no difference in the four quartiles. In multivariate analysis, after adjusting for confounding factors, the highest NLCR quartile (>20.25) was associated with increased 28-day all-cause mortality [hazard ratio (HR) 1.22, 95% Cl: 1.01-1.49; P=0.046]. The areas under the receiver operating characteristic curves (AUROCs) for NLCR was 0.553 (95% CI: 0.529-0.576) for 28-day mortality. Conclusions High NLCR (>20.25) is independently related to increased 28-day all-cause mortality in adult septic patients of a limited sensibility and specificity. Further large multi-center prospective studies are needed to confirm such relationship and to validate whose clinical significance.

Relationship of Platelet Counts and Inflammatory Markers to 30-Day Mortality Risk in Patients with Acute Type A Aortic Dissection. BIOMED RESEARCH INTERNATIONAL 2020; 2020:1057496.

Abstract
Markers of prothrombotic state and inflammation are associated with the prognosis of patients with acute type A aortic dissection (AAAD). However, it is unclear that the relationship between these biomarkers and their combined impact on risk stratification. The present study evaluated the prognostic value of platelet counts, lymphocyte to neutrophil ratio (LNR), and lymphocyte to monocyte ratio (LMR), alone and in combination. A retrospective analysis of clinical data of 744 AAAD patients was conducted to identify whether these biomarkers were related to the 30-day mortality risk. A Kaplan-Meier analysis and log-rank test were used to compare survival between groups. A Cox hazard regression multivariable analysis was performed for 30-day mortality. Individual biomarker (platelet count, LNR, or LMR) was unable to predict 30-day mortality. However, combinations of all three biomarkers provided additive predictive value over either marker alone, the receiver operating characteristic (ROC) model had a prediction probability of 0.739 when platelet counts, LNR, and LMR were included. Cox hazard regression multivariable analysis showed that combinations of all three biomarkers were the strongest predictor of 30-day mortality (p < 0.021). Combined with these three easily measurable biomarkers at admission, they could help identify AAAD patients with a high risk of 30-day mortality.

Abstract
BACKGROUND AND AIMS Risk stratification in acute myocardial infarction (AMI) is important for guiding clinical management. Current risk scores are mostly derived from clinical trials with stringent patient selection. We aimed to establish and evaluate a composite scoring system to improve short-term mortality classification after index episodes of AMI, independent of electrocardiography (ECG) pattern, in a large real-world cohort. METHODS Using electronic health records, patients admitted to our regional teaching hospital (derivation cohort, n = 1747) and an independent tertiary care center (validation cohort, n = 1276), with index acute myocardial infarction between January 2013 and December 2017, as confirmed by principal diagnosis and laboratory findings, were identified retrospectively. RESULTS Univariate logistic regression was used as the primary model to identify potential contributors to mortality. Stepwise forward likelihood ratio logistic regression revealed that neutrophil-to-lymphocyte ratio, peripheral vascular disease, age, and serum creatinine (NPAC) were significant for 90-day mortality (Hosmer- Lemeshow test, p = 0.21). Each component of the NPAC score was weighted by beta-coefficients in multivariate analysis. The C-statistic of the NPAC score was 0.75, which was higher than the conventional Charlson's score (C-statistic = 0.63). Judicious application of a deep learning model to our dataset improved the accuracy of classification with a C-statistic of 0.81. CONCLUSIONS The NPAC score comprises four items from routine laboratory parameters to basic clinical information and can facilitate early identification of cases at risk of short-term mortality following index myocardial infarction. Deep learning model can serve as a gatekeeper to facilitate clinical decision-making.

Abstract
The application of a simple blood test to predict prognosis in acute heart failure (AHF) patients is not well established. Neutrophil-lymphocyte ratio (NLR) is inexpensive and easy to obtain in hospitalized patients using a routine blood test. We evaluate the prognostic implications of NLR as an independent predictor of in-hospital and long-term mortality in AHF patients. Among 5625 patients enrolled in the Korean Acute Heart Failure registry, 5580 patients were classified into quartiles by their NLR level, and analyzed for in-hospital and post-discharge three-year mortality. Patients in the highest NLR quartile had the highest in-hospital and post-discharge three-year mortality. The same results were seen by dividing the aggravating factor into the infection or ischemia group and the non-infection or non-ischemia group. For patients aggravated from infection or ischemia, a cut-off NLR value was 7.0 that increase the risk of in-hospital and post-discharge three-year mortality. In subgroups of patients not aggravated from infection or ischemia, a cut-off NLR value was 5.0 that increase the risk of in-hospital and post discharge three-year mortality. Elevated NLR in AHF patients at the index hospitalization is an independent predictor for in-hospital and post-discharge three-year mortality. Taken together, NLR is a marker for risk assessment of AHF patients.

Abstract
BACKGROUND In recent years, many studies focused on the association between the neutrophil-to-lymphocyte ratio (NLR) and the risk of intravenous immunoglobulin (IVIG)-resistant Kawasaki disease (rKD), with inconsistent results. Therefore, we aimed to investigate the role of NLR as a biomarker in detecting rKD. METHODS We searched PubMed, EMBASE, the Cochrane Central Register of Controlled Trials, and China National Knowledge Infrastructure through May 18th, 2019. Meta-disc 1.4 and STATA 15.1 were used to perform this metaanalysis in a fixed/random-effect model. RESULTS A total of 7 relevant studies were eligible to analyze pooled accuracy. The overall performance of NLR detection was: pooled sensitivity, 0.66 (95% confidence interval [CI], 0.63 - 0.70); pooled specificity, 0.71 (95%CI, 0.69 - 0.73); and area under the summary receiver operating characteristic curves value (SROC), 0.7956. The meta-regression analysis showed that the type of samples was the sources of heterogeneity. The subgroup analysis suggested that NLR detection after the initial treatment of IVIG had the largest area under curve of SROC in all the subgroups: pooled sensitivity, 0.58 (95%CI, 0.53 - 0.63); pooled specificity, 0.77 (95%CI, 0.75 - 0.79); and SROC, 0.8440. CONCLUSIONS This is the first meta-analysis demonstrated that NLR might be a biomarker for detecting rKD, especially NLR value after the initial treatment of IVIG. More well-designed researches need to be done to launch the application of NLR for predicting rKD in the clinic.

Abstract
Background To evaluate the prognostic value of pretreatment lymphocyte counts with respect to clinical outcomes in patients with solid tumors. Methods Systematic literature search of electronic databases (Pubmed, Embase and Web of Science) up to May 1, 2018 was carried out by two independent reviewers. We included Eligible studies assessed the prognostic impact of pretreatment lymphocytes and had reported hazard ratios (HR) with 95% confidence intervals (CIs) for endpoints including overall survival (OS) and progression-free survival (PFS). Only English publications were included. Results A total of 42 studies comprising 13,272 patients were included in this systematic review and meta-analysis. Low pretreatment lymphocyte count was associated with poor OS (HR = 1.27, 95% CI 1.16–1.39, P < 0.001, I2 = 58.5%) and PFS (HR = 1.27, 95% CI 1.15–1.40, P < 0.001, I2 = 25.7%). Subgroup analysis disaggregated by cancer type indicated that low pretreatment lymphocytes were most closely associated with poor OS in colorectal cancer followed by breast cancer and renal cancer. Conclusions Low pretreatment lymphocyte count may represent an unfavorable prognostic factor for clinical outcomes in patients with solid tumors.

Eur J Obstet Gynecol Reprod Biol 2019; 245:84-88. [PMID: 31884150 DOI: 10.1016/j.ejogrb.2019.12.009] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2019] [Revised: 11/24/2019] [Accepted: 12/22/2019] [Indexed: 11/16/2022]
Abstract
OBJECTIVE We aimed to investigate whether the neutrophil to lymphocyte ratio (NLR) may assist in the prediction of post CS infections. STUDY DESIGN This was a case control study performed at the Soroka University Medical Center, a large tertiary teaching medical center, between the years 2012-2016. Cases (post CS infection) were matched to controls (without post CS infection) in a proportion of 2:1. Matching was done according to surgery setting (elective vs. urgent) and date of surgery. Various demographic, clinical and obstetrical characteristics were collected. Laboratory tests that were taken 6-24 h postoperatively were compared between the study groups. Univariate analysis was followed by a multivariate one. Area under the curve was calculated for selected indices. RESULTS During the study period 113 patients who developed postoperative infection were compared with 224 healthy controls. Among patients in the study group, 71.7 % were diagnosed with surgical site infection, 7.1 % with endometritis and 21.2 % with other infections. Total neutrophil and lymphocyte counts were significantly higher among patient in the study group. NLR as well as platelet to lymphocyte (PLR) ratio were significantly higher among patients during the first 24 postoperative hours. NLR and PLR were found to be independently associated with post CS infection controlling for surgery length, use of hemostatic agents/adhesion barrier and skin closure technique (aOR 1.11 95 % CI 1.06-1.17, aOR 1.004 95 % CI 1.001-1.006, respectively). A performance analysis for NLR showed an area-under-the receiver operating curve (AUC) of 67 % (P = 0.006). CONCLUSION NLR is an easy readily available tool that may have a predictive value in early detection of post CS infection. Further studies are needed in order to support our findings before clinical implications of these findings can be recommended.

Elevated neutrophil-to-lymphocyte ratio can predict procedural adverse events in patients with ST-elevation myocardial infarction undergoing primary percutaneous coronary intervention. Coron Artery Dis 2019; 30:20-25. [PMID: 30334819 DOI: 10.1097/mca.0000000000000671] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 01/27/2023]
Abstract
BACKGROUND Elevated neutrophil-to-lymphocyte ratio (NLR) is an indirect marker of inflammation, and is associated with adverse clinical outcomes in patients with ST-segment elevation myocardial infarction (STEMI). The aim of this study was to investigate the usefulness of NLR to predict procedural adverse events is patients who underwent primary percutaneous coronary intervention (PCI). PATIENTS AND METHODS Consecutive patients with STEMI who underwent primary PCI were divided into low and high NLR, whereas high was defined as an NLR value above 75° percentile (≥9.45). The occurrence of procedural complications, in-hospital, and 30-day major adverse cardiovascular events and 1-year all-cause mortality were evaluated. RESULTS We included 664 patients with a mean age of 60.5 (±12.1) years and 66.3% were male. In multivariate analysis, NLR remained an independent predictor of in-hospital death [relative risk (RR)=1.03; 95% confidence interval (CI)=1.00-1.08; P=0.04], contrast-induced nephropathy (RR=2.35; 95% CI=1.11-4.71; P=0.02), distal embolization (RR=2.72; 95% CI=1.55-4.75; P<0.001), and no-reflow (RR=2.31; 95% CI=2.31-4.68; P=0.01). The area under the curve for distal embolization was 0.67, 0.64 for no-reflow and 0.62 for procedural complications. A low value of NLR had an excellent negative predictive value of 97.8, 96.9, and 92.1 for distal embolization, no-reflow, and procedural complications, respectively. CONCLUSION High NLR is an independent predictor of distal embolization, no-reflow, and procedural complications in patients with STEMI who underwent primary PCI. A low NLR value has an excellent negative predictive value for these procedural outcomes. NLR may be a useful and inexpensive tool that may be used at bedside.
