High Neutrophil-to-lymphocyte Ratio Group Research Articles

Correlations of baseline neutrophil-lymphocyte ratio with prognosis of patients with lupus nephritis: A single-center experience.

We aimed to evaluate the correlations among the neutrophil-to-lymphocyte ratio (NLR), lupus nephritis (LN) clinical characteristics, and renal prognosis of patients with LN. We enrolled 122 patients who were diagnosed with LN at the Rheumatology Department of the People's Hospital, Xinjiang Uygur Autonomous Region from January 2013 to April 2022. We determined the occurrence of renal adverse events in patients with LN by reviewing medical records and follow-up data. Correlations were analyzed using the Spearman test, and the quartile method was applied to classify all of the 122 patients who had completed follow-up into low, medium, and high NLR groups. The Kaplan-Meier survival curve was used to conduct survival analysis, and Cox regression analyses were used to explore possible potential risk factors. The baseline NLR of patients with LN was positively correlated with C-reactive protein (CRP), serum creatinine, blood urea nitrogen, and systemic lupus erythematosus disease activity index scores (P < 0.05) and negatively correlated with estimated glomerular filtration rate (eGFR) and serum albumin (P < 0.05). Patients who completed follow-up were divided into three NLR groups based on their NLR values: 30 in the low (NLR ≤ 2.21), 62 in the medium (NLR > 2.21 and NLR ≤ 6.17), and 30 in the high NLR group (NLR > 6.17). The patient survival time before developing poor renal prognosis was significantly different among the three groups (P < 0.05). High NLR (hazard ratio [HR] = 3.453, 95% confidence interval [CI]: 1.260-9.464), CRP (HR = 1.009, 95% CI: 1.002-1.017), eGFR (HR = 0.979, 95% CI: 0.963-0.995), and 24-h proteinuria values (HR = 1.237, 95% CI: 1.025-1.491) as well as anti-double stranded DNA antibody positivity (HR = 3.056, 95% CI:1.069-8.736) were independent risk factors associated with a poor renal prognosis for patients with LN. The baseline NLR in peripheral blood can be used as a reference index for evaluating renal function and disease activity in patients with LN, and a high NLR has predictive value for the prognosis of patients with LN.

Correlation between preoperative peripheral blood NLR, PLR, LMR and prognosis of patients with head and neck squamous cell carcinoma

BackgroundMarkers that can be used to evaluate the prognosis of patients with head and neck squamous cell carcinoma (HNSCC) remain undefined.ObjectiveThis study aimed to investigate the prognostic impact of preoperative neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and lymphocyte-to-monocyte ratio (LMR) in patients with HNSCC who underwent surgery-based treatment for the first time.MethodsThis retrospective study included patients HNSCC who underwent surgery-based treatment at our institution between January 2018 and December 2020. Specificity and sensitivity were analyzed using receiver operating characteristic (ROC) curves and the critical value was determined. Patients were divided into low and high groups according to NLR, PLR, and LMR the critical value. Log-rank and Cox proportional hazards models were used to evaluate the associations between preoperative NLR, PLR, LMR, and overall survival (OS).ResultsA total of 304 patients with HNSCC were included, of whom 190 (62.5%) and 114 (37.5%), 203 (66.8%) and 101 (33.2%), 98 (32.2%), and 206 (67.8%) cases were classified as low NLR and high NLR groups, low PLR and high PLR groups, and low LMR and high LMR groups, respectively. Univariate analysis showed that white blood cell count (WBC), neutrophil count (NEU), platelet count (PLT), NLR, pathologic N stage (pN stage), TNM stage and postoperative complications were significantly associated with OS (p < 0.05). Multivariate analysis showed that NEU, NLR, TNM stage and postoperative complications were independent negative prognostic factors for HNSCC (p < 0.05).ConclusionPreoperative NLR is an independent negative prognostic factor for HNSCC. Patients with an increased NLR may have a poor OS.

Significance of Neutrophil-to-Lymphocyte Ratio, Platelet-to-Lymphocyte Ratio and Monocyte-to-Lymphocyte Ratio in the Prognosis of Newly Diagnosed Multiple Myeloma Patients

Background Multiple myeloma is a cancer of the plasma cells, characterized by abnormal proliferation in the bone marrow. In 2023 about 12,590 deaths are expected to occur secondary to the disease. It is important to identify the predictors of disease progression for prognostication.Tumor microenvironment influences the growth of malignant plasma cells. Neutrophilia can enhance tumor growth, angiogenesis and provide a favorable matrix for metastasis. Lymphopenia is also suggestive of disease progression. Hence, an increased neutrophil-to-lymphocyte ratio (NLR) has been linked with a poor prognosis in many cancers. Monocytes are thought to be recruited by tumor cells for suppressing the immune cells and aiding in prolonged survival. In patients with multiple myeloma, a low platelet count is linked to a worse prognosis since a greater marrow myeloma burden leads to inhibition of thrombopoiesis.Hence, a low platelet-to-lymphocyte ratio (PLR) and high monocyte-to-lymphocyte ratio (MLR) are linked with worse prognosis.The aim of our study was to investigate the role of NLR, PLR and MLR in the prognosis of our patients. Methods This is a retrospective study that analyzed patients diagnosed with Multiple Myeloma from 2012 to 2022 at Saint Vincent Cancer Center, Worcester, Massachusetts. We performed a chart review and collected demographics including age at the time of diagnosis, gender, BMI, race. Additionally, we also collected data such as multiple myeloma type, R-ISS staging, complete blood count (cbc), chemotherapy used, auto stem cell transplant, 5-year survival. NLR, PLR and MLR were calculated based on pre-treatment cbc. Based on literature review, cutoffs for High NLR (≥2), Low NLR (&amp;lt;2), High PLR (≥120.00), low PLR (&amp;lt;120.00) and high MLR (≥0.27), and low MLR (&amp;lt;0.27) were made. SPSS was used for analysis of the data. A logistic regression was used to calculate the Odd's ratio (OR). A p value less than equal to 0.05 was considered significant. Results The total number of patients analyzed were 97. 47.4% (n=46) were females and 52.6% (n=51) were males. Mean age at diagnosis was 69.3 years. Mean BMI was 30.16 kg/m 2. 35.1% (n=34) of the patients had IgG subtype. 36.1% (n=35) of our study population belonged to R-ISS stage 2. 38.1% (n=37) of the patients were treated with lenalidomide, bortezomib, dexamethasone combination. Mean NLR was 3.4, mean PLR was 166.949 and mean MLR was 0.46. 66% (n=64) of the patients belonged to the high NLR group, 61.9% (n=60) to the high PLR group and 64.9% (n=63) to the high MLR group. Out of 97 patients, 56.7% (n=55) were alive at 5 years. High NLR (≥2) was associated with lower odds of 5-year survival with a p value of 0.037 and a 95% confidence interval (0.095-0.931). High MLR (≥0.27) was associated with lower odds of 5-year survival with a p value of 0.042 and a 95% confidence interval (0.124-0.962). PLR did not correlate with 5-year survival and was not statistically significant (p value of 0.157). Conclusions Based on our study, a high NLR (≥2) and high MLR (≥0.27) were associated with lower odds of 5-year survival. Hence NLR and MLR are independent prognostic factors in newly diagnosed multiple myeloma patients which can be economical and effective methods for early evaluation of patient prognosis.

Association between the neutrophil-to-lymphocyte ratio and risk of in-hospital heart failure and arrhythmia in patients with acute myocardial infarction.

This study was to probe into the relationship between the neutrophil-to-lymphocyte ratio (NLR) and both in-hospital and long-term heart failure risk in patients with acute myocardial infarction (AMI). 990 patients with AMI, including 386 with non-ST-segment elevation myocardial infarction (NSTEMI) and 604 with segment elevation myocardial infarction (STEMI) were recruited between January 2019 and March 2022. The in-hospital acute heart failure (AHF) and arrhythmia events were recorded. The NLR was significantly greater in the AHF group in STEMI and NSTEMI patients, with a higher frequency of arrhythmia in comparison to the non-AHF group. A high NLR was related to a high level of myocardial injury markers, accompanied with more AHF and arrhythmia events. Multivariate logistic regression analyses revealed that high NLR is independently linked with increased in-hospital AHF and arrhythmia risk. Receiver operating characteristic curve analyses revealed that the prognostic value of NLR for in-hospital AHF was 0.704 in STEMI patients and 0.766 in NSTEMI patients. However, during a median follow-up of 28 months with 32 heart failure patients, there was no significant difference between the low NLR group (n = 18) and the high NLR group (n = 14). Further analysis showed that the two groups did not significantly differ in the occurrence of heart failure within 12 months of discharge. Our results indicate that NLR is an independent risk factor of in-hospital AHF in AMI patients. However, NLR has no value in predicting long-term heart failure.

Prognostic value of systemic inflammation response index in hepatoblastoma patients receiving preoperative neoadjuvant chemotherapy.

Inflammation is closely associated with tumor development and patient prognosis. The objective of this study is to assess the prognostic value of the preoperative inflammatory indexes in pediatric hepatoblastoma patients who receive neoadjuvant chemotherapy. A retrospective analysis was performed on clinical and pathological data of 199 hepatoblastoma patients who underwent hepatectomy with preoperative neoadjuvant chemotherapy from January 2015 to June 2020. The receiver operating characteristic curve was used to evaluate the prognostic value of neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), systemic immune-inflammation index (SII), and systemic inflammation response index (SIRI) in predicting OS and EFS. Patients were grouped based on optimal cutoff values of preoperative inflammatory indexes. Survival rates were calculated using the Kaplan-Meier method, and survival outcomes were compared between groups using the log-rank test. Univariate and multivariate Cox proportional hazards regression models were used to identify independent prognostic factors, and a nomogram was constructed using R software to predict the probability of OS. The receiver operating characteristic curve showed prognostic value for OS, not EFS, in preoperative inflammatory indexes. Patients were categorized into low/high groups: SII ≤ 266.70/higher, NLR ≤ 1.24/higher, PLR ≤ 85.25/higher, and SIRI ≤ 0.72/higher. High NLR, PLR, SII, and SIRI groups had significantly lower 5-year OS than their low counterparts (all p-value < 0.05). The Cox analysis identified four independent prognostic factors: SIRI (HR=2.997, 95% CI: 1.119-8.031), microvascular invasion (HR=2.556, 95% CI: 1.14-5.73), the post-treatment extent of disease (POSTTEXT) staging (IV vs. I: HR=244.204, 95% CI:11.306-5274.556), and alpha-fetoprotein (>100 ng/ml: HR=0.11, 95% CI: 0.032-0.381) for hepatoblastoma patients with neoadjuvant chemotherapy. High SIRI group had more patients with adverse NLR, SII, and POSTTEXT III (all p-value < 0.05). Independent prognostic factors led to an OS nomogram with a concordance index of 0.85 (95% CI: 0.78-0.91, p-value = 1.43e-27) and the calibration curve showed a good fit between the prediction curve and the true curve. SIRI is an independent prognostic factor of hepatoblastoma patients receiving neoadjuvant chemotherapy. The OS nomogram based on SIRI, POSTTEXT staging, MiVI, and AFP can be used to assess the prognosis of those patients.

A high platelet-to-lymphocyte ratio predicts all-cause mortality and cardiovascular mortality in maintenance hemodialysis patients

Purpose The aim of this study was to further assess whether the platelet-to-lymphocyte ratio (PLR) is independently associated with all-cause mortality and cardiovascular mortality in maintenance hemodialysis (MHD) patients. Methods From January 1, 2014, to December 31, 2014, patients undergoing regular hemodialysis in the Blood Purification Center of the General Hospital of Northern Theatre Command were retrospectively selected. A total of 303 MHD patients were enrolled in accordance with the inclusion and exclusion criteria. For each patient, the endpoint of follow-up was either death or December 31, 2021. The primary endpoints were all-cause and cardiovascular death. A receiver operating characteristic (ROC) curve was drawn to detect the predictive ability of PLR, and the optimal critical value of PLR was determined to be 107.57. Kaplan–Meier curves and Cox proportional analysis were used to assess the prognostic value of PLR. We used the same method to evaluate the correlation between the neutrophil-to-lymphocyte ratio (NLR) and the prognosis of MHD patients. Results At the end of follow-up, 128 MHD patients had progressed to all-cause death, and 73 MHD patients had progressed to cardiovascular death. In multivariate Cox regression, both the high PLR group and the high NLR group were independently associated with all-cause mortality (HR 2.608, 95% CI 1.579–4.306, p < .001 vs. HR 1.634, 95% CI 1.023–2.610, p = .04). Only high PLR expression was associated with cardiovascular mortality (HR 3.379, 95% CI 1.646–6.936, p = .001). Conclusions High PLR levels can independently predict all-cause and cardiovascular mortality in MHD patients.

227. RELATIONSHIP BETWEEN 90-DAY PROGNOSIS NUTRITIONAL INDEX AND INFLAMMATORY RESPONSE MARKERS AND LONG-TERM SURVIVAL IN ESOPHAGEAL CANCER

Abstract Background The incidence rate of esophageal cancer in Asia is mainly squamous cell carcinoma, which is characterized by high mortality and poor prognosis. The prognosis of tumors is not only related to the biological characteristics of tumor cells, but also closely related to the nutritional status and inflammatory response of patients. The aim of this study is to investigate the relationship between nutritional index (PNI) and inflammatory response markers (NLR, LMR) at 90 days after surgery and long-term survival in patients with esophageal squamous cell carcinoma. To provide reference for accurately assessing the condition, identifying survival risks, and improving long-term prognosis. Methods The data of ESCC patients who underwent radical resection for esophageal cancer from April 2018 to November 2018 were extracted (n = 66). Calculate the prognostic nutritional index (PNI), neutrophil-to-lymphocyte ratio (NLR), lymphocyte-to-monocyte ratio (LMR) and other indicators of patients at 90 days after operation. ROC was used to calculate the cut-off values of PNI, NLR, and LMR. KaplanMeier survival curve was used to analyze the relationship between different PNI, NLR, LMR levels and long-term survival of patients. All patients were followed up regularly after surgery, and the last follow-up time was April 2023. Results The best cut-off values of PNI, NLR, and LMR were 42.8, 3.27, and 4.76, respectively. Kaplan Meier survival analysis showed a correlation between postoperative PNI, NLR, LMR at 90 days and overall survival and disease-free survival. At 90 days after surgery, the OS (P = 0.007) and DFS (P = 0.038) of patients in the high PNI group (PNI ≥ 42.8) were better than those in the low PNI group; The OS (P = 0.002) and DFS (P = 0.048) of patients in the low NLR group (NLR &amp;lt; 3.27) were better than those in the high NLR group; The OS (P = 0.001) and DFS (P = 0.039) of patients in the high LMR group (LMR ≥ 4.76) were better than those in the low LMR group. Conclusions PNI, NLR, and LMR are important predictors of OS and DFS in patients with esophageal squamous cell carcinoma after radical resection of esophagus. Patients with PNI ≥ 42.8, NLR&amp;lt;3.27, and LMR ≥ 4.76 at 90 days after surgery have better OS and DFS.

The predictive role of hematologic markers in resectable NSCLC patients treated with neoadjuvant chemoimmunotherapy: a retrospective cohort study.

Neoadjuvant chemoimmunotherapy is an important therapeutic modality for resectable nonsmall cell lung cancer (NSCLC). The roles of the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio, and lymphocyte-to-monocyte ratio in predicting the efficacy and prognosis of patients with resectable NSCLC receiving neoadjuvant chemoimmunotherapy remain uncertain. This study aimed to explore the association of baseline and preoperative NLR, platelet-to-lymphocyte ratio, and lymphocyte-to-monocyte ratio with the treatment response and survival of patients with resectable NSCLC treated with neoadjuvant chemoimmunotherapy. Data of patients with resectable NSCLC treated with neoadjuvant chemoimmunotherapy between May 2019 and July 2022 at our institute, were retrospectively analyzed. Peripheral blood cell counts were obtained at baseline and before surgery. Data that may affect treatment efficacy were also collected and analyzed, including age, sex, BMI, cumulative smoking exposure, pathological type, clinical stage, PD-L1 tumor proportion score, immune checkpoint inhibitors, dosage of neoadjuvant therapy, duration from final therapy to surgery, and baseline and preoperative oncological markers. The present work has been reported in compliance with REporting recommendations for tumor MARKer prognostic studies (REMARK) criteria and guidelines (Supplemental Digital Content 1, http://links.lww.com/JS9/A860 ). A total of 116 patients were included in the study. Univariate logistic regression analysis showed that a higher baseline NLR ( P =0.001) and preoperative NLR ( P =0.001) were associated with a lower incidence of pathological complete response (pCR) following neoadjuvant therapy. Multivariate analysis indicated that a lower incidence of pCR was achieved in the high baseline NLR group ( P =0.014). Higher baseline NLR ( P =0.021), preoperative NLR ( P =0.004) and higher preoperative CEA levels ( P =0.059) were associated with shorter disease-free survival (DFS). Multivariate Cox proportional hazard regression analyses showed that shorter DFS was achieved in the high preoperative NLR group ( P =0.033). In patients with resectable NSCLC treated with neoadjuvant chemoimmunotherapy, a higher baseline NLR was associated with a lower incidence of pCR, and a higher preoperative NLR was associated with a shorter DFS. However, a future prospective study with a large sample size and long-term follow-up is needed to verify the predictive value of NLR in these patients.

Influence of Pre-treatment Lymphocyte/Monocyte Ratio and Neutrophil/Lymphocyte Ratio on the Prognosis of Patients with Extranodal NK/T-Cell Lymphoma

To explore the influence of lymphocyte-to-monocyte ratio (LMR) and neutrophil-to-lymphocyte ratio (NLR) on the prognosis of patients with extranodal NK/T cell lymphoma (ENKTL). The clinical data of 203 patients with ENKTL admitted to the First Affiliated Hospital of Zhengzhou University from January 2011 to January 2020 were retrospectively analyzed. The ROC curve determined the limit values of LMR and NLR; Categorical variables were compared using a chi-square test, expressed as frequency and percentage (n,%). Continuous variables were expressed as medians and extremes and compared with the Mann-Whitney U test; Progression-free survival (PFS) and overall survival (OS) of different grouped LMR and NLR patients were analyzed using Kaplan-Meier curves and compared with log-rank tests. The COX proportional risk regression model was used to perform one-factor and multi-factor analysis of PFS and OS. The optimal critical values of LMR and NLR were determined by the ROC curve, which were 2.60 and 3.40, respectively. LMR≤2.60 was more likely to occur in patients with bone marrow invasion (P=0.029) and higher LDH (P=0.036), while NLR≥3.40 was more likely to occur in patients with higher ECOG scores (P=0.002), higher LDH (P=0.008), higher blood glucose (P=0.024), and lower PLT (P=0.010). Kaplan-Meier survival analysis showed that PFS and OS of patients in the high LMR group were significantly better than the low LMR group, while PFS and OS in the low NLR group were significantly better than the high NLR group. The results of multivariate COX analysis showed that EBV-DNA positive (P=0.047), LMR≤2.60 (P=0.014), NLR≥3.40 (P=0.023) were independent risk factors affecting PFS in patients with ENKTL. LMR≤2.60 (P<0.001), NLR≥3.40 (P=0.048), and high β2-MG (P=0.013) were independent risk factors affecting OS in patients with ENKTL. Low LMR and high NLR before treatment are associated with poor prognosis in patients with ENKTL, which also can be used as an easily testable, inexpensive, and practical prognostic indicator in the clinic.

Neutrophil-to-lymphocyte ratio as a predictor of immune checkpoint inhibitor therapy response in advanced bladder cancer.

e16586 Background: Immune checkpoint inhibitor (ICI) therapy is a novel and promising agent for treating muscle invasive bladder cancer (MIBC). However, there is a need for further understanding of which patient factors or biological markers can be used to help identify patients who will have a successful response to ICI therapy. We hypothesized that Neutrophil-to-Lymphocyte Ratio (NLR) could be predictive of response to ICI therapy as this ratio has previously been reported to correlate with a higher number of myeloid derived suppressor cells. Methods: A retrospective cohort analysis was performed on patients with advanced or metastatic bladder cancer who were treated with ICI therapy at a single institution between 2015-2020. Information on survival, disease recurrence, and patient characteristics was gathered. Neutrophil and lymphocyte numbers were recorded at time of ICI administration and a ratio of neutrophils to lymphocytes was calculated. The median of these values was calculated and used to divide the cohort into low NLR and high NLR. Tissue samples from a subset of these patients were collected and sent for multiplex immunohistochemistry with a myeloid and T cell staining panel. Results: In a cohort of 115 patients with advanced bladder cancer treated with ICI, the mean time to last follow up or event (death or disease progression) was 375.78 days (SD 41). 35 patients (30%) had either a complete or partial response to ICI therapy. A Kaplan Meier survival analysis shows a significant difference in survival between the low and high NLR group, with lower NLR having a longer event free survival (Wilcoxon rank p = 0.0156). Multiplex IHC showed variable tumor and adjacent microenvironmental distributions of myeloid and lymphoid marker positive populations in ICI responders and non-responders. Conclusions: In an effort to better predict which patients may benefit from ICI therapy, we have studied NLR at the time of ICI administration and its association with event free survival. Our results suggest that a lower NLR could be associated with a longer event free survival. Further research is being conducted to study the immune microenvironment as it relates to bladder cancer response to ICI therapy.

THE ROLE OF NEUTROPHIL TO LYMPHOCYTE RATIO IN TOXICITY AND RESPONSE OF HEAD AND NECK CANCER PATIENTS TREATED WITH CONCURRENT CHEMORADIATION

Background- Neutrophil to Lymphocyte Ratio (NLR) is a haematogical marker which signies inammatory burden and treatment outcome of a malignancy. We investigated prognostic value of NLR in Head and Neck Squamous Cell Carcinoma (HNSCC) patients treated with concurrent chemoradiotherapy. To compare acute toxicity, locoregional control, disease burden w Aims &amp; Objective- ith patients with high (&gt;4) and low (≤4) NLR groups. Head and neck squamous cell carcinoma patients treated with concurre Materials And Methods- nt chemoradiotherapy were retrospectively selected from the records of Department of Radiation Oncology, Medical College Kolkata between 2018-2021. Baseline Neutrophil to Lymphocyte Ratio (NLR) was calculated using Differential Leucocyte Count (DLC) of Complete Blood Count (CBC) measured 10 days before the treatment initiation. An NLR value of greater than 4 has been considered as high. Data regarding stage at presentation, acute oral mucositis, acute dysphagia, anaemia, clinicoradiological response to treatment at 6 weeks after completion of chemoradiation were taken. ResultsWe analysed 150 patients between 2018-2021. Primary sites were oral cavity (37.3%), oropharynx (24%), hypopharynx (10.7%), larynx (28%). Our data suggests high baseline NLR correlates with poor prognosis because of more disease burden and poor treatment response. More numbers of locally advanced disease (T3 &amp; T4) belong to high NLR group (P value= &lt;0.0001). Grade II or more acute toxicities i.e oral mucositis, dysphagia was observed in high NLR group (P value &lt;0.0001), which were statistically signicant. Complete radiological response is lower in high NLR group, which was statistically signicant (P Value = &lt;0.0001). Mean Local Recurrence Free Survival (In Months) was less in high NLR group, this was also statistically signicant. This study suggests that in head and neck squamous c Conclusion- ell carcinoma, high NLR is correlated with higher stage of presentation, more acute locoregional toxicity during chemoradiotherapy, poor response to therapy and low local recurrence free survival (In Months)

Relationship between Neutrophil to Lymphocyte Ratio (NLR) and Gensini Score in Patients with Coronary Artery Disease (CAD) at Mataram City General Hospital: A Cross Sectional Study

Highlights: It discusses the relationship between NLR and the severity of coronary atherosclerosis. There is significant difference from the previous NLR research Abstract: Background. Neutrophil to Lymphocyte Ratio (NLR) is a marker of systemic inflammation correlated with the incidence of Coronary Artery Disease (CAD). Neutrophils infiltrate the coronary artery plaque causing acceleration of atherosclerosis. T lymphocyte recruitment is required at the early stages of plaque formation. Previous studies have shown that heightened NLR was correlated with the percentage of stenosis at the site of the multivessel lesion. Aims. This study aimed to determine the relationship between NLR with Gensini score of coronary arteries in CAD patients at Mataram City General Hospital. Material and method. This was a cross sectional study conducted in Mataram City General Hospital. Fifty-nine patients diagnosed with CAD participated in the study. Blood collection and coronary angiography were performed to assess NLR and Gensini Score. The main variables were NLR and Gensini Score. Gensini score of 1-29 was considered as mild atherosclerosis and Gensini score of 30 or more was considered as severe atherosclerosis. NLR was considered high if the value of NLR were &gt; 2.385 based on previous studies. Spearman test was performed to assess correlation between variables. Results. Approximately 53% subjects were categorized as severe atherosclerosis and 48% as mild atherosclerosis. The median values of Gensini score in the low NLR group were 25.0 and in the high NLR group were 40.0 (p=0,19). The median values of NLR in the mild group of atherosclerosis were 1.78 and in the severe atherosclerotic group were 2.15 (p=0,59). There was no significant difference in NLR between severe atherosclerosis and mild atherosclerosis groups. NLR was not associated with Gensini score (p=0,32). Conclusions. There was no significant relationship between Neutrophil to Lymphocyte Ratio with Gensini score of coronary arteries in CAD patients at Mataram City General Hospital.

The association between neutrophil to lymphocyte ratio (NLR) with mortality in patients with perforated peptic ulcer at Dr. Soetomo Hospital in Surabaya, Indonesia

Background: Perforated peptic ulcer is the most dangerous complication of peptic ulcer. Neutrophils and lymphocytes are crucial in the inflammatory process. A simple and effective biomarker to assess systemic inflammation is the neutrophil-lymphocyte ratio (NLR). This study aims to ascertain the connection between NLR and mortality in peptic ulcer patients. Methods: This study was a cross-sectional observational analytic study. Data were obtained from medical records in Dr. Soetomo General Hospital from January 2018 to December 2022. The dependent variable was patient mortality, while NLR value served as the independent variable. NLR cutoff value calculated using the Receiver Operating Characteristic (ROC) curve. The collected data was tested using the Chi-square test and the Spearman rank correlation test integrated in the SPSS software. Results: There were 109 patients, consisting of 74 male and 35 female patients. There were 29 patients with the Boey Score category 1, 54 patients with the Boey score category 2, and 25 patients with the Boey score 3. Using a cutoff of 15.60, the NLR values were separated into low and high NLR groups. There were 56 patients with high scores and 53 patients with low scores. A significant relationship was found between NLR values and mortality (p &lt;0.0001). The results of Spearman's analysis revealed a strong correlation between the incidence of mortality and an increase in the NLR value (p&lt;0.0001; r = 0.500). Conclusion: There is a significant relationship between NLR and mortality in patients with perforated peptic ulcers.

Inflammatory biomarkers predict outcomes of patients with radioactive iodine refractory thyroid cancer treated with sorafenib.

The objective of this multicenter, retrospective cohort study was to evaluate the ability of inflammatory biomarkers representing the host immune system to predict outcomes in 70 patients with progressive radioactive iodine (RAI)-refractory thyroid cancer who were treated with sorafenib. Patients were divided into low and high inflammatory biomarker groups based on median values. Progression-free survival (PFS) and overall survival (OS) were assessed based on the lymphocyte-to-monocyte ratio (LMR), neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR). The median LMR, NLR, and PLR values were 3.4, 2.2, and 140.1, respectively. No significant differences were observed in baseline characteristics of high and low LMR, NLR and PLR groups. Median PFS values were 6.6 and 19.5 months in the low and high LMR groups, respectively (P < 0.001). Compared with the high NLR and PLR groups, PFS was significantly prolonged in the low NLR and PLR groups (P = 0.003 and P = 0.041 respectively). In the multivariate analysis, low LMR and high NLR were associated with poor PFS after adjusting for multiple confounding factors including age, sex, pathology, disease-related symptoms, serum thyroglobulin level, lung-only metastasis, cumulative RAI dose, time from diagnosis, and longer diameter of the target lesion (hazard ratio, HR = 2.42; 95% confidence interval, CI 1.25-4.71; P = 0.009, and HR = 2.09; CI, 1.06-4.14; P = 0.033, respectively). High LMR, low NLR, and low PLR were significantly associated with prolonged OS (P = 0.011, P = 0.023, and P = 0.007, respectively). Patients with at least one risk factors for inflammatory biomarkers presented a significantly lower PFS (HR 2.29; CI, 1.36-3.84; P = 0.003) and OS (HR 2.95; CI, 1.49-5.81; P = 0.006) than patients without any risk factor. Baseline inflammatory biomarkers successfully predicted PFS and OS in patients with progressive RAI-refractory thyroid cancer treated with sorafenib. These prognostic biomarkers might help arrive at appropriate clinical decisions regarding the use of sorafenib.

Predictive Value of Neutrophil-to-Lymphocyte Ratio at Admission for Chest X-Ray Progression in Hospitalized COVID-19 Patients

Objective: Previous studies focused on using the neutrophil-to-lymphocyte ratio (NLR) to monitor COVID-19 patients as an early warning signal of severe COVID-19 infection. Results showed that NLR could also be used as a prognostic factor. In the present study, the role of NLR in predicting chest X-ray (CXR) progression in hospitalized COVID-19 patients was investigated. Materials and Methods: The present study was an ambispective observational cohort study that included COVID-19 patients admitted to the isolation ward and COVID-19 intensive care unit between July and September 2021 in Buddhasothorn Hospital, Chachoengsao, Thailand. NLR and demographic findings were analyzed. Results: Medical details of 564 patients were retrospectively analyzed using 3.24 as the cut-off value of the maximum Youden index to classify a high NLR group and a low NLR group. The estimated cumulative hazard function for CXR progression in the high NLR group was statistically significant, (HR 1.31, 95% CI 1.02 to 1.68, p=0.031). Univariate analysis suggested that high NLR value and three or more clinical risk factors (age 60 years or older, diabetes mellitus, chronic obstructive pulmonary disease, chronic kidney disease, cirrhosis, stroke, obesity, and immunocompromised) were associated with CXR progression, while multivariate analysis determined high NLR as an independent predictive marker for COVID-19 CXR progression (aOR 1.54, 95% CI 1.06 to 2.23, p=0.022). Using NLR along with pre-existing comorbidity risk factors significantly increased the predictive value for COVID-19 CXR progression (area under the ROC curve 0.565, p=0.017). Conclusion: High NLR at the time of hospitalization was identified as a simple predictor for COVID-19 CXR progression requiring close monitoring.

The Prognostic Value of Neutrophil-to-Lymphocyte Ratio in Patients with Metastatic Renal Cell Carcinoma.

Metastatic renal cell carcinoma (mRCC) is an aggressive cancer characterised by an increased recurrence rate and an inadequate response to treatment. This study aimed to investigate the importance of the neutrophil-to-lymphocyte ratio (NLR) as a prognostic marker for long-term survival in patients with mRCC. We retrospectively analysed data from 74 patients with mRCC treated at our medical centre with tyrosine kinase inhibitors (TKIs) and immune checkpoint inhibitors (ICIs). We evaluated the predictive value of NLR for overall survival (OS) in these patients. The median OS was 5.1 months in the higher NLR group (≥3) and 13.3 months in the lower NLR group (<3) (p < 0.0001). There was no significant difference in the OS between the TKI and ICI therapies in the low NLR group (12.9 vs. 13.6 months, p = 0.411) or in the high NLR group (4.7 vs. 5.5 months, p = 0.32). Both univariate and multivariate analyses revealed that a higher NLR was an independent prognostic factor of long-term survival in patients with mRCC treated with first-line therapy. This retrospective study showed that adding NLR to other Memorial Sloan Kettering Cancer Center (MSKCC) and International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) variables might improve the prognostic and predictive power of these models.

The Neutrophil-to-Lymphocyte Ratio as a Predictor of Postoperative Outcomes in Patients Undergoing Coronary Artery Bypass Grafting.

The neutrophil-to-lymphocyte ratio (NLR) has been suggested as a novel predictive marker of cardiovascular disease. However, its prognostic role in patients undergoing coronary artery bypass grafting (CABG) is unclear. This study aimed to determine the association between the preoperative NLR and early mortality in patients undergoing CABG. Cardiac surgery was performed in 2,504 patients at Seoul St. Mary's Hospital from January 2010 to December 2021. This study retrospectively reviewed 920 patients who underwent isolated CABG, excluding those for whom the preoperative NLR was unavailable. The primary endpoints were the 30- and 90-day mortality after isolated CABG. Risk factor analysis was performed using logistic regression analysis. Based on the optimal cut-off value of preoperative NLR on the receiver operating characteristic curve, high and low NLR groups were compared. The 30- and 90-day mortality rates were 3.8% (n=35) and 7.0% (n=64), respectively. In the multivariable analysis, preoperative NLR was significantly associated with 30-day mortality (odds ratio [OR], 1.28; 95% confidence interval [CI], 1.17-1.39; p<0.001) and 90-day mortality (OR, 1.17; 95% CI, 1.07-1.28; p<0.001). The optimal cut-off value of the preoperative NLR was 3.4. Compared to the low NLR group (<3.4), the high NLR group (≥3.4) showed higher 30- and 90-day mortality rates (1.4% vs. 12.1%, p<0.001; 2.8% vs. 21.3%, p<0.001, respectively). Preoperative NLR was strongly associated with early mortality after isolated CABG, especially in patients with a high preoperative NLR (≥3.4). Further studies with larger cohorts are necessary to validate these results.

STUDY OF NEUTROPHIL TO LYMPHOCYTE RATIO AS A PROGNOSTIC MARKER IN ACUTE ST ELEVATED MYOCARDIAL INFARCTION

Objectives: Previous studies have demonstrated the role of inflammation in acute STEMI. We examined cellular inflammatory response to STEMI in the blood and its association with in-hospital mortality and/or adverse clinical events. The neutrophil-to-lymphocyte ratio (NLR) was found to be a useful inflammatory marker for predicting adverse outcomes. We hypothesized that an elevated neutrophil-to-lymphocyte ratio would be associated with increased adverse outcomes in patients with acute STEMI. Material and Methods: The study consisted of 100 patients with acute STEMI who were admitted in various wards of M.B.S. Hospital, Kota in year 2018-20, after obtaining informed consent. The complete blood cell count (CBC) was obtained from all patients within 12-24 hours of the onset of symptoms. Total leukocytes were counted and differential count was obtained for neutrophils, lymphocytes and neutrophil/lymphocyte ratio (NLR) were evaluated. The patients were divided into two groups [High NLR and Low NLR] according to their admission NLR results. Association of cellular response (NLR) with the incidence of post-MI mortality/complications was assessed by using chi-square test with yates correction. Results showed that patients with increase Results: d NLR at admission were having increased in hospital complication and mortality at 5 days. In-hospital mortality and post-STEMI complication rate were 9% and 42%, respectively. Patients in high NLR group had higher rate of complications (69.4% vs. 26.5%, p &lt;0.001) and death (19.4% vs. 3.12%, p=0.018) in hospital than those in low NLR group. Cardiogenic shock (36.11% vs.3.12%, p &lt;0.001), pulmonary edema (44.44% vs. 9.37%, p&lt;0.001), heart failure (55.55% vs. 23.43%, p=0.003), arrhythmias (33.33% vs. 9.37%, p =0.006) occurred more in high NLR group. Risk factors were not found to have a major impact on NLR. Differences of the risk factor data in the both groups were not statistically significant (P &gt; 0.05) in our study. It can be concluded that in patients with acute STEMI, NLR can be tak Conclusion: en as simple, inexpensive, reproducible and universally available inflammatory biomarkers for determining in-hospital mortality and complications.

Neutrophil-to-Lymphocyte ratio as a prognostic marker of mortality and disease severity in septic Acute kidney injury Patients: A retrospective study

BackgroundAcute kidney injury (AKI) is a frequent complication of sepsis associated with increased mortality and morbidity. The neutrophil-to-lymphocyte ratio (NLR) has been shown as a risk factor for septic AKI. In this study, we aimed to further evaluate NLR’s prediction value on the prognosis of septic AKI patients. MethodsSeptic AKI patients at a tertiary university-affiliated medical center were retrospectively enrolled from August 2015 to August 2021. The primary outcomes were 30-day and 90-day mortality, and secondary outcomes were disease severity, length of stay, and rehospitalization in survivors. Kaplan–Meier curves, Cox proportional hazards, cubic spline and logistics regression analyses were performed for adverse outcomes basing on NLR. The predictive value of NLR on morality was also estimated by the area under the receiver operating characteristic curve (AUROC). ResultsA total of 309 septic AKI patients were included with a mean age of 57.8 ± 18.1 years and 92 (29.8 %) being female. The 30-day mortality was 43.4 % and 90-day morality was 61.8 %. When divided by the median of NLR at hospital admission, patients in the high NLR group were associated with an increased 30-day/90-day mortality. After adjusting for multiple covariates, the predictive value of NLR remained significant for 30-day mortality (HR: 2.96, 95 % CI: 1.48–5.92, p = 0.002) and 90-day mortality (HR: 1.88, 95 % CI: 1.11–3.16, p = 0.018).NLR at admission had the highest AUROC (0.618) for 30-day mortality compared with other parameters such as white blood cell (0.573), neutrophil (0.579), lymphocyte (0.567), platelet (0.546), BUN (0.580), albumin (0.545), C-reactive protein (0.571) and procalcitonin (0.534). A similar predictive value on mortality was also observed for NLR measured at septic AKI diagnosis. For secondary outcomes, high NLR was associated with increased risk of transfer to ICU, mechanical ventilation, stage-3 AKI and renal replacement therapy, but not with length of hospital/ICU stay or long-term rehospitalization. ConclusionHigh NLR is independently associated with 30-day/90-day mortality and disease severity in septic AKI patients. NLR may serve as an economic and widely available biomarker of septic AKI prognosis.

Neutrophil-to-lymphocyte ratio may predict clinical relapse in ulcerative colitis patients with mucosal healing.

Endoscopic mucosal healing (MH) is an important treatment goal for patients with ulcerative colitis (UC). The neutrophil-to-lymphocyte ratio (NLR) reflects systemic inflammation and has been reported to be a useful predictive marker for UC. This study aimed to evaluate the clinical utility of the NLR for predicting clinical relapse in UC patients with MH. We retrospectively enrolled patients with UC who underwent colonoscopy at the Osaka City University Hospital between January 2010 and December 2010, whose Mayo Endoscopic Subscore was 0 or 1. The correlation between the incidence of relapse and demographic factors, including the NLR, was analyzed. We included 129 patients in the present study. The median NLR at the time of endoscopy was 1.98, and differences in the high NLR group and the low NLR group were compared. During a median follow-up period of 46.4 months, 58 patients (45.0%) experienced relapse. The cumulative relapse-free rate was significantly higher in the low NLR group than in the high NLR group (P = 0.03, log-rank test). Multivariate analysis identified high NLR as an independent prognostic factor for clinical relapse (hazard ratio, 1.74; 95% confidence interval, 1.02-2.98; P = 0.04). NLR is a novel and useful predictor of clinical relapse in UC patients with MH, and it can potentially be a strong indicator to determine the appropriate treatment strategy and decision-making in clinical practice.
