Specificity Of Neutrophil To Lymphocyte Ratio Research Articles

A meta-analysis of predictive value of blood biomarkers in gestational trophoblastic neoplasia.

Background: Neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) have been reported to play a diagnostic and predictive role in gestational trophoblastic disease. However, the conclusions are still ambiguous. This meta-analysis aimed to evaluate the combined predictive value of NLR and PLR in the malignant progression of gestational trophoblastic disease. Method: Electronic databases including PubMed, Embase, the Cochrane Library, Web of Science, Chinese National Knowledge Infrastructure, Wanfang and China Biomedical Literature Database were searched for the relevant literature published up to 1October 2022. Study selection and data extraction were performed independently by two reviewers. All analyses wereperformed using Revman, MetaDisc and STATA software. Results: A total of 858 patients from five studies were included in this meta-analysis. The pooled sensitivity and specificity of NLR were 0.8 (95% CI: 0.71-0.88) and 0.73 (95% CI: 0.69-0.76), respectively, and the area under curve of the summary receiver operating curvewas 0.81. The pooled sensitivity and specificity of PLR were 0.87 (95% CI: 0.75-0.95) and 0.49 (95% CI: 0.44-0.54), respectively, and the area under curve of thesummary receiver operating curvewas 0.88. I2 statistic and Deek's funnel plot showed no heterogeneity and publication bias. Conclusion: NLR can accurately predict the progression from hydatidiform mole to gestational trophoblastic neoplasia and is a promising biomarker in further follow-up.

Navigating the Haematological Maze: Unraveling the Role of NLR and PLR as Predictors of Dengue Severity- A Cross-sectional Study from Southern India

Introduction: Dengue Fever (DF) poses a critical public health threat in tropical regions, displaying a spectrum of manifestations without distinct diagnostic hallmarks. Neutrophil to Lymphocyte Ratio (NLR) and Platelet to Lymphocyte Ratio (PLR) are useful biomarkers of inflammation and prognostic markers in various diseases. The inflammation that occurs in dengue is due to the exaggerated response of the immune system. Aim: To assess the utility value of NLR and PLR as prognostic markers for dengue severity. Materials and Methods: A cross-sectional study was conducted on 99 admitted Dengue patients. Patients were grouped into three categories: DF, Dengue Haemorrhagic Fever (DHF), and Dengue Shock Syndrome (DSS). Various parameters of Complete Blood Count (CBC), NLR, and PLR were compared among the groups using Analysis of Variance (ANOVA) test (p-value <0.05 considered significant). Sensitivity, specificity, and accuracy were calculated using Receiver Operating Characteristic (ROC) curve. Results: Among the 99 patients, 63.6% exhibited thrombocytopenia (platelet count <1.5 lac/dL), and 7% of patients had a platelet count <20,000/dL. All DHF and DSS patients had thrombocytopenia. Leucopenia was evident in 45.45% of patients, with 6% having a Total Leukocyte Count (TLC) <2000/dL. TLC remained stable across these stages. The mean NLR in DF was 2.47 (range 0.1-15.4), in DHF it was 1.013 (range 0.2-3.2), and in DSS it was 0.41 (range 0.08- 0.65.17) with a p-value of 0.02. The PLR displayed substantial differences, with mean values of 134.4 (range 10.1-273.8) for DF, 50.57 (range 7.1-96.1) for DHF, and 10.39 (range 3.1-38.8) for DSS with a p-value of 0.003. NLR had 63% accuracy, 77.8% sensitivity, and 94.4% specificity. PLR had 81.5% accuracy, 93.3% sensitivity and 33.3% specificity. Conclusion: The specificity of NLR was higher, while PLR exhibited superior accuracy and sensitivity in detecting severe cases.

Role of Neutrophil to Lymphocyte Ratio (NLR) and C-Reactive Protein to Albumin Ratio (CAR) as Early Predictors of Severity in Acute Pancreatitis

Background: Acute pancreatitis (AP) is a life-threatening disease caused by a variety of factors, and once it progresses to severe acute pancreatitis, the prognosis is poor. Different modalities are available for predicting severity in acute pancreatitis. A single, cheap, widely available marker with high sensitivity and specificity is yet to be identified. Aims and objectives: The present study was aimed to determine the relation of the neutrophil-lymphocyte ratio (NLR) and CRP-Albumin ratio (CAR) in early prediction of severity in acute pancreatitis. Materials and methods: This cross-sectional study was conducted at the Department of Gastrointestinal, Hepatobiliary and Pancreatic Disorders (GHPD), BIRDEM General Hospital, Shahbagh, Dhaka, Bangladesh, from April, 2020 to March, 2022. Diagnosis of acute pancreatitis was made by clinical findings, serum amylase and lipase levels (>3 times the upper limit of normal values), evidences of acute pancreatitis by ultrasonography and computed tomography (CT). Severity of acute pancreatitis was classified according to the revised version of Atlanta classification. Data collection was done through a structured questionnaire. Data were analyzed by SPSS 23. Receiver operating characteristic (ROC) curve was constructed to estimate the sensitivity and specificity of NLR and CAR. Results: A total of 120 patients with acute pancreatitis were enrolled in this study. Age of the patients was 45.20±13.93 (mean ±SD) years, male predominance was observed (54.2%). Majority of the cases were mild 52.5% (n=63) compared to moderate 28.3% (n=34) and severe 19.2% (n=23). The NLR was 6.63±3.344 (Mean ± SD) with a range of 1.32 to 18.75. The CAR was 3.20±2.23 (Mean ±SD) with range of 0.14-7.20. The area under the curve (AUC) of NLR and CAR were 0.865 and 0.949 for severity of AP respectively. Sensitivity, specificity, PPV, NPV and accuracy of NLR at cut-off ≥5.72 were 80.7%, 76.2%, 75.4%, 81.4% & 78.3% and that of CAR at cut-off ≥2.07 were 96.5%, 76.2%, 78.6%, 96.0% & 85.8%. Conclusion: This study revealed that NLR and CAR are good predictors in the assessment of severity of AP. These easily accessible and low-cost inflammatory markers can be used for the management of acute pancreatitis. Bangladesh Crit Care J September 2023; 11 (2): 83-89

Neutrophil-to-lymphocyte ratio is associated with stroke progression and functional outcome in patients with ischemic stroke.

The objective of the present research was to examine the correlation between the neutrophil-to-lymphocyte ratio (NLR) and stroke progression (SP) as well as the functional outcome following an ischemic stroke (IS). The current study was conducted as prospective observational research. A cohort of 341 participants diagnosed with IS was included in the study from March 2019 to August 2021. This study's primary measure of interest was the occurrence of SP within the initial week following hospital admission. The secondary outcome was functional status 3 months after IS as measured by a modified Rankin scale score. The association between NLR with SP, and poor functional outcomes was examined using multivariate logistic regression. The predictive value of NLR for SP and poor functional outcomes was evaluated using the receiver operating characteristic (ROC) curve. Among the 341 enrolled patients, 56 (16.4%) had SP, and 285 (83.6%) had no SP. The results of the multivariate logistic regression analysis demonstrated that the existence of diabetes mellitus and the NLR were independently associated with SP and poor functional outcomes. The area under the ROC curve of NLR in predicting poor functional outcome was 0.6117 (95% confidence interval, .5341-.6893, p=.0032), and the optimal cut-off point was 4.2139. The sensitivity and specificity of NLR in predicting poor functional outcomes were 52.7% and 72.0%, respectively. Patients with acute IS exhibited a very high incidence of SP. NLR may be a valuable prognostic indicator in clinical practice because it was independently associated with SP and a poor functional outcome.

Increased neutrophil-to-lymphocyte ratio is associated with unfavorable functional outcomes in acute pontine infarction

BackgroundThe neutrophil-to-lymphocyte ratio (NLR) is positively associated with unfavorable outcomes in patients with cerebral infarction. This study aimed to investigate the relationship between the NLR and the short-term clinical outcome of acute pontine infarction.MethodsPatients with acute pontine infarction were consecutively included. Clinical and laboratory data were collected. All patients were followed up at 3 months using modified Rankin Scale (mRS) scores. An unfavorable outcome was defined as an mRS score ≥ 3. Receiver operating characteristic (ROC) curve analysis was used to calculate the optimal cutoff values for patients with acute pontine infarction. risk factors can be predictive factors for an unfavorable outcome after acute pontine infarction.ResultsTwo hundred fifty-six patients with acute pontine infarction were included in this study. The NLR was significantly higher in the unfavorable outcome group than in the favorable outcome group (P < 0.05). Additionally, the infarct size was significantly higher in the high NLR tertile group than in the low NLR tertile group (P < 0.05). Multivariate logistic regression analysis revealed that the baseline National Institutes of Health Stroke Scale (NIHSS) score, NLR, platelet count, and fasting blood glucose (FBG) level were significantly associated with unfavorable outcomes 3 months after acute pontine infarction. The optimal cutoff value of the NLR for predicting the 3-month outcome of acute pontine infarction was 3.055. The negative and positive predictive values of NLR were 85.7% and 61.3%, respectively, and the sensitivity and specificity of NLR were 69.2% and 80.9%.ConclusionsWe found that the NLR may be an independent predictive factor for the outcome of acute pontine infarction.

Prognostic Role of Neutrophil to Lymphocyte Ratio in Nonalcoholic Fatty Liver Disease: A Systematic Review and Meta-Analysis.

Nonalcoholic steatohepatitis (NASH) and liver fibrosis are the most common complications of nonalcoholic fatty liver disease (NAFLD). In this systematic review and meta-analysis, we aim to analyze the current literature to evaluate the association of neutrophil to lymphocyte ratio (NLR) with NASH and fibrosis in patients with NAFLD. PubMed, Web of Science, and Scopus were used to conduct a systematic search for relevant publications published before May 24, 2022. The Newcastle-Ottawa scale was used for quality assessment. Thirteen studies were included in our study. The pooled results showed that NAFLD patients with significant NASH had elevated levels of NLR compared to those with nonsignificant or without NASH (SMD = 0.97, 95% CI = 0.59-1.39, p < 0.001). The pooled sensitivity and specificity of NLR were 78.16% (95% CI = 73.70%-82.04%), and 76.93% (95% CI = 70.22%-82.50%), respectively. In addition, NAFLD patients with significant liver fibrosis had elevated levels of NLR compared to those with nonsignificant or without fibrosis (SMD = 1.59, 95% CI = 0.76-2.43, p < 0.001). The pooled sensitivity and specificity of NLR were 82.62% (95% CI = 70.235%-90.55%) and 81.22% (95% CI = 75.62%-85.78%), respectively. Our findings support NLR to be a promising biomarker that can be readily integrated into clinical settings to aid in the prediction and prevention of NASH and fibrosis among patients with NAFLD.

Peripheral Blood Neutrophil-to-lymphocyte Ratio as a Predictor of Functional Outcomes in Patients with Hemorrhagic Stroke.

BackgroundPeripheral blood neutrophil-to-lymphocyte ratio (NLR) has recently emerged as a prognostic biomarker in many disease states. The aim of this study was to evaluate the diagnostic utility of NLR to predict poor functional outcomes in patients with hemorrhagic stroke and to compare it with the intracranial hemorrhage (ICH) score.Materials and methodsPatients who presented to the emergency department with clinical features suggestive of stroke were evaluated with computed tomography (CT) brain to identify ICH. The ICH scores and NLR were estimated at the time of admission. Modified Rankin Scale (mRS) score equal to or greater than 3 at 90 days was used to define poor functional outcomes (major disability or death). Receiver operating characteristic (ROC) curve was plotted with NLR and the ICH score to analyze and compare their discriminative ability to predict poor functional outcomes.ResultsA total of 158 patients were recruited for the study. One hundred and seven patients were found to have poor functional outcomes as per their mRS score at 90 days. The mean NLR and the ICH scores at presentation were significantly higher for the poor outcome group (6.57 and 2.83) compared to the good outcome group (2.75 and 1.49). The ROC analysis revealed that both NLR and the ICH scores were good predictors of functional outcomes at 90 days with area under the curve (AUC) of 0.814 and 0.819, respectively. The sensitivity and specificity of NLR were 84 and 66.3% and those of the ICH score were 66.7 and 78.3% to predict poor functional outcomes.ConclusionIn patients with hemorrhagic stroke, NLR at admission is a good predictor of functional outcomes at 90 days. When compared to the ICH score, NLR is more sensitive but less specific in predicting poor functional outcomes.How to cite this articleBabu S, Pulicken M, Thazhathuveedu AK.

Predictive Value of Systemic Immune-Inflammation index and Neutrophil-to-Lymphocyte Ratio in Patients with Severe COVID-19.

Objective: It was initially reported that a novel coronavirus (COVID-19) had been identified in Wuhan, China, in December 2019.To date, COVID-19 is still threatening all humanity and has affected the public healthcare system and the world economic situation. Neutrophil-to-lymphocyte ratio (NLR) has also been demonstrated that associated with severity of COVID-19, but little is known about systemic immune-inflammation index (SII) relation with COVID-19. Methods: One hundred and twenty-five patients with diagnosed COVID-19 including non-severe cases (n = 77) and severe cases (n = 48) were enrolled in this study. Each patient of clinical characteristic information, blood routine parameters, and the haemogram-derived ratios were collected, calculated, and retrospectively analyzed. Receiver operating characteristics (ROC) was performed to investigate whether these parameters could be used to the predictive value of patients with severe COVID-19. Results: White blood cell count (WBC), neutrophil count (NEU), red cell volume distribution width (RDW), NLR, Platelet to lymphocyte ratio (PLR), neutrophil-to-platelet ratio (NPR), and SII were significantly higher in the severe groups than in the non-severe group (p < 0.01).Conversely, the severe group had a markedly decreased lymphocyte count, basophil (Baso#) count, red blood cell count (RBC), Hemoglobin (HGB), hematocrit (HCT), and lymphocyte-to-monocyte ratio (LMR) (P < 0.01).ROC curve analysis showed the AUC, optimal cut-off value, sensitivity, specificity of NLR and SII to early predict severe-patients with COVID-19 were 0.867, 7.25, 70.83%, 92.21% and 0.860, 887.20, 81.25%, 81.82%, respectively. Conclusion The results suggest that the SII and NLR is a potential new diagnosed biomarker in severe-patients with COVID-19.

The neutrophil-to-lymphocyte ratio in complete blood cell count may be an available marker for active adult-onset Still's disease

In clinical practice, acute-phase protein measurements during inflammation are usually used to monitor the activity and severity of adult-onset Still's disease (AOSD).Objective: to study the possibility of using the neutrophil-to-lymphocyte ratio (NLR) in complete blood cell count as a marker for the activity and severity of AOSD in clinical practice.Patients and methods. The investigation enrolled 48 patients (29 females and 19 males; mean age, 32.8±12.5 years) with active AOSD, who met the criteria devised by M. Yamaguchi et al. Along with standard clinical and laboratory parameters and systemic scores, NLR was calculated in complete blood cell count.Results and discussion. There was a statistically significant correlation of NLR with the level of CRP (r=0.532), ferritin (r=0.43), ESR (r=0.40), and the systemic score reflecting the severity of the disease (r=0.449), which allows NLR to be regarded as a tool that is convenient to assess the activity and severity of AOSD in clinical practice.Conclusion. The findings have shown the good sensitivity and specificity of NLR, which indicates the possibility of using the latter as an available marker for assessing the activity and severity of AOSD in clinical practice.

Early predictors of small-for-gestational-age neonates using non-invasive, low-cost, and readily available hematological markers.

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. 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. 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). 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.

Exploring the prognostic value of the neutrophil-to-lymphocyte ratio in cancer

In cancer patients, a high pre-treatment neutrophil-to-lymphocyte ratio (NLR) is associated with poorer survival outcomes. Significant variation in the magnitude of this association has been observed between studies, but sources of this variation are poorly understood. Here, we explore differences in the prognostic potential of NLR between patient subgroups stratified by demographic and clinical characteristics using a retrospective cohort of 5,363 patients treated at Moffitt Cancer Center (Tampa, FL). We identify patients for whom NLR has maximum prognostic potential via adjusted hazard ratios (HRs) calculated using multivariable Cox proportional hazards models and area under the curve analysis. NLR demonstrates stronger associations (HRs > 2) with survival among African-American patients, patients receiving radiation therapy, stage IV patients, and melanoma patients when compared with the overall study population (HR = 1.58). Sensitivity and specificity of NLR as a prognostic marker are also higher in these patient subgroups, and increase further with combinations of multiple “high-risk” demographic or clinical characteristics. In summary, NLR may have greater prognostic value in patients with certain demographic and clinical features. Future prospective studies could validate this hypothesis, after further characterization of populations in which NLR has maximum prognostic potential and the identification of meaningful thresholds for risk stratification.

NEUTROPHIL-TO-LYMPHOCYTE AND PLATELET-TO-LYMPHOCYTE RATIOS PREDICT ALL-CAUSE MORTALITY IN ACUTE PULMONARY EMBOLISM

SESSION TITLE: Monday Abstract Posters SESSION TYPE: Original Investigation Posters PRESENTED ON: 10/21/2019 02:30 PM - 03:15 PM PURPOSE: Acute pulmonary embolism (PE) is a leading cause of cardiovascular mortality. PE is risk stratified utilizing the pulmonary embolism severity index, vital signs, and markers of right ventricular dysfunction. We sought to investigate the utility of the neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) to predict all-cause mortality in PE patients. METHODS: Three hundred acute PE patients between March 2016 and December 2018 were retrospectively analyzed. Demographic information, vitals, co-morbidities, echocardiographic findings, and complete blood count with differential at the time of diagnosis were documented. Patients with sepsis, infection, chronic inflammatory conditions, and active cancer were excluded from further analysis. Furthermore, patients who did not have a complete blood count with differential at the time of PE diagnosis were also excluded. NLR and PLR were calculated by dividing absolute granulocyte count and platelet count by absolute lymphocyte count, respectively. Correlation analysis was performed by calculating the Spearman rank-order correlation coefficient. Receiver operating characteristic curve was constructed to illustrate the sensitivity and specificity of NLR and PLR to predict all-cause mortality. RESULTS: We identified 192 patients who met the study selection criteria. Twenty-eight patients died during follow-up. No significant difference in NLR and PLR was observed between patients with low risk, submassive, and massive PE (p = 0.895 | p = 0.345). Elevated NLR and PLR was associated with all-cause mortality (p = 0.017 | p = 0.021). NLR strongly correlated with PLR (p < 0.001; R = 0.736). PLR correlated with right/left ventricular ratio (p = 0.002, R = -0.232). Both NLR and PLR correlated with PESI score (p < 0.001; R = 0.269 | p = 0.019; R = 0.169). Neither NLR nor PLR correlated with BNP, lactate, or troponin (p = 0.832; p = 0.881; p = 0.799 | p = 0.745; p = 0.577; p = 0.079). NLR of 5.46 was associated with all-cause mortality with sensitivity of 75.0% and specificity of 67.1% (AUC: 0.692; p = 0.001). PLR of 256.6 was associated with all-cause mortality with sensitivity of 53.6% and specificity of 82.3% (AUC: 0.692; p = 0.001). CONCLUSIONS: Elevated NLR and PLR were associated with all-cause mortality in acute PE. The elevation of NLR and PLR may reflect the presence of systemic inflammation. Further studies are needed to ascertain the pathophysiologic process that underlies the associations with all-cause mortality. CLINICAL IMPLICATIONS: NLR and PLR are simple biomarkers that are readily available from routine laboratory values and may be useful components of risk prediction models.

Neutrophil-to-Lymphocyte Ratio in Adult Community-Acquired Pneumonia Patients Correlates with Unfavorable Clinical Outcomes

Despite the extensive improvement in antibiotic treatment and medical care, severe adult community-acquired pneumonia (CAP) remains as the significant cause of death worldwide. Earlier prognosis assessment and timely treatment in adult CAP patients are useful for prognosis. The neutrophil-to-lymphocyte ratio (NLR) in blood routine has a broad application possibility in assessing inflammatory reaction and prognosis. The aim of this study was to examine the relationship between NLR and inflammatory reaction and to unravel the usefulness of NLR in the assessment of clinical outcomes in adult CAP patients. This retrospective study was conducted based on adult patients with a primary diagnosis of CAP. All patients included received a routine blood test and calculated NLR. All of the measurement data were analyzed with paired t-test and the enumeration data were analyzed with χ2 test. Multivariate analysis was performed to investigate the association between predictors (age, male, CURB-65 scores, comorbidity, NLR, and other inflammatory cells in blood routine) and unfavorable outcomes of CAP (ICU admission and 30-day mortality). Receiver operating characteristic curves (ROC) were used to evaluate the sensitivity and specificity of NLR in predicting unfavorable outcomes of CAP. One hundred fifty patients were included. Compared with favorable outcomes group, age, CURB-65 scores, WBC, neutrophil and lymphocyte counts, and NLR were elevated in unfavorable outcomes group (p < 0.05), gender and coexisting illness did not differ obviously. Multivariate logistic regression model analysis showed CURB-65 scores and NLR were independent predictors correlated with unfavorable outcomes (p < 0.05). The area under the ROC curve (AUC) of NLR was 0.81 (95% CI 0.73 to 0.89), the sensitivity was 81.00% and specificity was 72.8%. NLR is superior to CURB-65 in predicting unfavorable outcomes. NLR combined CURB-65 has better sensitivity and specificity (89.40% versus 91.30%). NLR is a simple, cheap, and rapidly available measurement in blood routine and is associated with unfavorable clinical outcomes in adult CAP patients.

Neutrophil-to-Lymphocyte Ratio Improves the Accuracy and Sensitivity of Pneumonia Severity Index in Predicting 30-Day Mortality of CAP Patients.

The pneumonia severity index (PSI) scoring system is one of the tools used to evaluate and predict the prognosis of patients with community-acquired pneumonia (CAP). Although PSI has been widely used in clinical studies of pneumonia, it is still rare to combine it with blood indexes to predict the prognosis of pneumonia. Neutrophil-to-lymphocyte ratio (NLR) is a promising candidate predictor of mortality in CAP patients. The aim of this study was to investigate the efficacy of pneumonia severity index combined with NLR in predicting 30-day mortality in CAP patients. We conducted a retrospective study. We analyzed data on 400 non-immune individuals over the age of 18 in this study. All patients received blood routine measurement and PSI score calculation after admission. The primary outcome measures were mortality and survival in CAP patients. The sensitivity and specificity of PSI score, NLR, and the combination of PSI score and NLR in predicting 30-day mortality were assessed using the subject operating characteristic curve (ROC). Data from 400 patients were analyzed, in which the 30-day mortality was 10.5% (42/400). The AUC of NLR and PSI in predicting 30-day mortality of CAP patients were 0.81 (95% CI 0.73 - 0.89) and 0.94 (95% CI 0.90 - 0.98), respectively, with statistically significant differences (p = 0.00). The sensitivity and specificity of NLR were 0.80 and 0.7, respectively. The sensitivity and specificity of PSI were 0.78 and 0.94, respectively. The combined AUC of the two indicators for predicting death in CAP patients was 0.95 (95% CI 0.92 - 0.99), and the sensitivity and specificity were 0.85 and 0.94, respectively. Neutrophil-to-lymphocyte ratio improves the accuracy and sensitivity of the pneumonia severity index in predicting 30-day mortality of CAP patients.

Predictive value of hematological parameters in testicular torsion: retrospective investigation of data from a high-volume tertiary care center.

ObjectiveTo investigate the use of hematological parameters in the differential diagnosis of testis torsion and epididymo-orchitis, and to determine the predictive value of these parameters in the diagnosis of testis torsion.MethodsThis study retrospectively reviewed the medical data of patients who presented to our institute with the complaint of acute scrotal pain. Eighty-five patients who had undergone orchiectomy or surgical detorsion due to testis torsion and 72 patients with epididymo-orchitis were included in the study. The control group comprised 78 healthy males. The groups were compared with respect to age, hematological parameters, neutrophil to lymphocyte ratio (NLR), monocyte to eosinophil ratio (MER), and platelet to lymphocyte ratio (PLR).ResultsThe monocyte count significantly differed between testis torsion and epididymo-orchitis, and was useful in the differential diagnosis. The mean neutrophil, platelet, and white blood cell counts, and the NLR, MER, and PLR values in the control group were significantly lower than those in the torsion and epididymo-orchitis groups.ConclusionThe sensitivity and specificity of NLR in predicting testis torsion were as high as the sensitivity and specificity of doppler ultrasonography, suggesting the possible use of this parameter in the diagnosis of testis torsion.

Neutrophil-to-lymphocyte ratio and mural nodule height as predictive factors for malignant intraductal papillary mucinous neoplasms

Background: Accurate preoperative prediction for malignant IPMN is still challenging. The aim of this study was to investigate the validity of neutrophil-to-lymphocyte ratio (NLR) and mural nodule height (MNH) for predicting malignant intraductal papillary mucinous neoplasm (IPMN).Methods: The medical records of 60 patients who underwent pancreatectomy for IPMN were retrospectively reviewed.Results: NLR tended to be higher in malignant IPMN (median: 2.23) than in benign IPMN (median: 2.04; p = .14). MNH was significantly greater in malignant IPMN (median: 16 mm) than in benign IPMN (median: 8 mm; p < .01). The optimal cutoff values for the NLR and MNH were 3.60 and 11 mm, respectively. The sensitivity and specificity of NLR ≥3.60 for predicting malignant IPMN were 40% and 93%, and those of MNH ≥11 mm were 73% and 77%, respectively. Univariate analysis revealed that NLR ≥3.60 (p < .01) and MNH ≥11 mm (p < .01) were significant predictive factors. On multivariate analysis, enhanced solid component was identified as an independent factor, but NLR ≥3.60 and MNH ≥11 mm were not.Conclusions: NLR and MNH are suboptimal tests in predicting malignant IPMN; however, they can be useful to assist in clinical decision-making.

Use of the neutrophil to lymphocyte ratio compare crp for the early prediction of acute pancreatitis severity?

Aim: To determine the usefulness of the neutrophil to lymphocyte ratio (NLR) as a diagnostic tool for the early detection and prediction of acute pancreatitis (AP) severity compared with that of C-reactive protein (CRP). Material and Methods: The medical records of 464 patients hospitalized with AP between 2006 and 2014 were reviewed. The patients were classified into two groups: severe AP (SAP) and mild/moderate AP groups. Lymphocyte and neutrophil counts and CRP levels at the time of admission were noted. Results: Out of the total number of patients (n = 464), 67 had severe AP. The median NLR was significantly higher in the SAP group (median of 11.1) than in the mild/moderate AP group (median of 6.9) (p < 0.0001). The sensitivity and specificity of NLR were 83.6% and 49.4%, respectively, with a cut-off value of 6.8 and an AUC of 0.68. CRP levels were also significantly higher in the SAP group (median of 189 mg/L) than in the mild/moderate AP group (median of 53.5 mg/L) (p < 0.0001). The sensitivity and specificity of the CRP values were 83.6 % and 74.9 %, respectively, with a cut-off value of 113 mg/L and an AUC of 0.83. Conclusion: The NLR was significantly higher in patients with severe AP. However, CRP measurement was superior to NLR as an early predictor of severe disease.

Neutrophil to lymphocyte ratio and platelet to lymphocyte ratio are predictive of chemotherapeutic response and prognosis in epithelial ovarian cancer patients treated with platinum-based chemotherapy

The aim of present study was to investigate the role of preoperative neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) used as prognostic markers for predicting chemotherapeutic response and survival outcomes in patients with epithelial ovarian cancer (EOC) who are receiving platinum-based chemotherapy. A total of 344 patients diagnosed with EOC who are receiving platinum-based chemotherapy from 2005 to 2010 in the hospital were enrolled. NLR and PLR were calculated from complete blood cell count taken before operation. The patients were divided into platinum-resistant (P-R) group and platinum-sensitive (P-S) group according to chemotherapeutic response. Clinicopathologic variables and outcomes were retrospectively collected and compared among groups. We used receiver operating characteristic (ROC) curves to calculate optimal cut-off values for NLR and PLR to predict chemotherapeutic response and prognosis. The AUC, sensitivity, specificity of NLR > 3.02 to predict platinum resistance were 0.819, 75.0% and 81.45%, respectively. The corresponding values of PLR > 207 were 0.727, 60.42% and 85.48%, respectively. Patients with lower value of NLR (NLR < 3.02) or PLR (PLR < 207) had a longer progression-free survival (PFS) and overall survival (OS). In multivariate analysis, NLR and PLR showed a significant association with PFS (hazard ratio [HR], 1.733; 95%CI, 1.225-2.453, P = 0.002 and HR, 1.952; 95%CI, 1.430-2.662, P < 0.001) and OS (HR, 1.616; 95%CI, 1.138-2.297, P = 0.007, and HR, 2.167; 95%CI, 1.565-3.000, P < 0.001). These results suggest that the assessment of NLR and PLR could assist the identification of patients with poor prognosis and had potential clinical value in predicting platinum resistance in patients with EOC.

Diagnostic value of the neutrophil-to-lymphocyte ratio and the combination of serum CA-125 for stages III and IV endometriosis

Background Currently, all the diagnostic indicators for endometriosis lack perfect sensitivity and specificity. According to the characteristic of endometriosis, we analyzed the new biomarker neutrophil-to-lymphocyte ratio (NLR) and the combination of NLR and serum CA-125 to investigate their diagnostic value for identifying stages III and IV endometriosis. Methods The values of serum CA-125 and routine blood tests were collected from 197 patients with endometriosis, 102 with benign tumors and 112 healthy individuals. We investigated the sensitivity and specificity of NLR and its combination with serum-CA-125 for diagnosing stages III and IV endometriosis by using receiver operating characteristic (ROC). Results The mean values of NLR, the combination of serum CA-125 and NLR (combination) of the groups with stages III and IV endometriosis were significantly higher than the other two groups. Serum CA-125, NLR, and the combined biomarkers could significantly discriminate the stages III and IV endometriosis group from the other two groups (P&lt;0.05). NLR shows a lower sensitivity of 57.9% and specificity of 65.2% with a cutoff value at 1.82. And the combination of biomarkers has the highest AUC of 0.949 with a sensitivity of 86.8% and specificity of 92.0% at the cutoff value of 44.40. In addition, for patients with negative CA-125, 55.36% and 53.57% of the patients were able to be diagnosed with endometriosis by using NLR alone and the combination of biomarkers. Conclusion For diagnosing stages III and IV endometriosis, the neutrophil-to-lymphocyte ratio is a better adjuvant to serum CA-125, and the neutrophil-to-lymphocyte ratio is valuable in diagnosing stages III and IV endometriosis for patients with negative serum CA-125.

Pre-treatment neutrophil to lymphocyte ratio is elevated in epithelial ovarian cancer and predicts survival after treatment.

Inflammatory cells can both suppress and stimulate tumor growth, and the influence of inflammatory cells on clinical outcome has been the focus of many studies. The purpose of this study was to evaluate the effectiveness of the neutrophil to lymphocyte ratio (NLR), a measure of the systemic inflammatory response, as an additional discriminative biomarker in epithelial ovarian cancer and to determine whether it predicts survival and recurrence. We studied 192 patients with epithelial ovarian cancer, 173 with benign ovarian tumors, 229 with benign gynecologic disease, and 405 healthy controls. Serum CA125 levels and leukocyte counts according to subtypes were recorded prior to treatment in all study subjects. In epithelial ovarian cancer, the diagnostic usefulness of NLR, in combination with CA125, was evaluated. The correlation between NLR and overall and disease-free survival was analyzed using both univariate and multivariate analyses adjusting for the known prognostic factors (age, stage, cell type, and grade). Preoperative NLR in ovarian cancer subjects (mean 6.02) was significantly higher than that in benign ovarian tumor subjects (mean 2.57), benign gynecologic disease subjects (mean 2.55), and healthy controls (mean 1.98) (P < 0.001). The sensitivity and specificity of NLR in detecting ovarian cancer was 66.1% (95% CI, 59.52-72.68%) and 82.7% (95% CI, 79.02-86.38%), respectively (cutoff value: 2.60). In early stage ovarian cancer, CA125 was not elevated in 19 out of 49 patients. Seven (36.8%) of these 19 patients were NLR positive. On Cox multivariate analysis, NLR positive, stage III/IV, and older age were independent poor prognostic factors, and being NLR positive was the most powerful predictive variable (Hazard Ratio = 8.42 [95% CI: 1.09-64.84], P = 0.041). Our findings provide evidence for the association between NLR and epithelial ovarian cancer. Preoperative NLR, in combination with CA125, may represent a simple and cost-effective method of identifying ovarian cancers, and an elevated NLR may predict an adverse outcome in ovarian cancer.
