In our meta-analysis, the pooled event rate estimated and the pooled hazard ratio were calculated using a random effect model.Results: Forty-two articles were selected for our analysis. The pooled risk difference for non-organ confined PCa between high and low NLR cases was 0.06 (95% confidence interval [CI]: −0.03-0.15) and between high and low PLR cases increased to 0.30 (95% CI: 0.16-0.43). In non-metastatic PCa cases, the pooled hazard ratio for overall mortality between high and low NLR was 1.33 (95% CI: 0.78-1.88) and between high and low PLR was 1.47 (95% CI: 0.91-2.03), whereas in metastatic PCa cases, between high and low NLR was 1.79 (95% CI: 1.44-2.13) and between high and low PLR was 1.05 (95% CI: 0.87-1.24).Conclusion: The prognostic values of NLR and PLR in terms of PCa characteristics and responses after treatment show a high level of heterogeneity of results among studies. These two ratios can represent the inflammatory and immunity status of the patient related to several conditions. A higher predictive value is related to a high NLR in terms of risk for overall mortality in metastatic PCa cases under systemic treatments.展开更多

We sought to make this comparison. Methods A total of 1355 elderly patients with CHF were analyzed. A multivariate logistic regression model was used to analyze the variables associated with atrial fibrillation （AF）. Cox regression analysis was used to assess the multivariable rela- tionship between the N/L ratio, NT-proBNP level, and subsequent major cardiovascular events （MCE）. Results In the multiple logistic regression analysis, the N/L ratio was demonstrated as a risk factor for AF in elderly patients with CHF [odds ratio （OR）： 1.079, 95% confi- dence interval （CI）： 1.027-1.134, P = 0.003]. The median follow-up period was 18 months. In a multivariable model using tertiles of both variables, the highest tertile of the N/L ratio was significantly associated with MCE [hazard ratio （HR）： 1.407, 95% CI： 1.098-1.802, P = 0.007] compared with the lowest tertile. Similarly, the highest NT-proBNP tertile was also significantly associated with MCE （HR： 1.461, 95% CI： 1.104-1.934, P- 0.008）. Conclusions In elderly patients with CHF, the N/L ratio is one of the important risk factors for AF and it is an inexpensive and readily available marker with similar independent prognostic power to NT-proBNP. The risk of MCE increases 1.407-fold when the N/L ratio is elevated to the highest tertile.展开更多

METHODS: With the aim of identifying the studies related to NLR, a search was conducted on http://www.ncbi.nlm.nih.gov/pubmed by utilizing the key words "neutrophil lymphocyte ratio, ocular diseases, and eye diseases" up to February 2018. All of the original articles were assessed according to date of publications, countries, clinics and topics. Studies about ocular inflammatory diseases were evaluated according to their qualifications, review methods and results. RESULTS: A total of 4473 publications, including original research articles and reviews were screened. The number of publications was shown a regular logarithmic increase over the years. The majority of studies were performed by clinics in Turkey and many of these publications were performed by oncology and cardiology clinics. A total of 75 publications were identified to be about ocular diseases. CONCLUSION: Elevated NLR as a cheap, reproducible, and readily available marker could be used as a diagnostic and/or prognostic marker in ocular diseases.展开更多

The demographics, laboratory analyses, and histopathology data were analyzed.RESULTS Overall survival(OS) and disease-free survival(DFS) were determined in the patients with a high(> 2.9) and low(≤ 2.9) NLR. The median OS and DFS duration in the high NLR group were significantly shorter than those in the low NLR group(OS: 6.2 mo vs 15.7 mo, respectively, P = 0.007; DFS: 2.2 mo vs 3.7 mo, respectively, P = 0.039). An NLR > 2.9 was identified as an independent predictor of a poor prognosis of OS(P = 0.034, HR = 1.866; 95%CI: 1.048-3.322) in uni-and multivariate analyses. Moreover, there was a significantly positive correlation between the NLR and the Child-Pugh score(r = 0.276, P = 0.015) and the maximum diameter of the tumor(r = 0.435, P < 0.001). Additionally, the NLR could enhance the prognostic predictive power of the CLIP score for DFS in these patients. CONCLUSION The preoperative NLR is a prognostic predictor after hepatectomy for HCC patients with PVTT/HVTT. NLR > 2.9 indicates poorer OS and DFS.展开更多

Fresh blood samples were collected before and after treatment, and flow cytometry was performed to assess the proportions of monocytic(m MDSCs) and granulocytic MDSCs(g MDSCs).Results: Median age was 58 years and 71(61.2%) patients were male. A baseline NLR≥2.94 was associated with significantly poorer progression-free survival(PFS) and overall survival(OS) vs. an NLR<2.94(P=0.011 and P=0.002, respectively). In multivariate analysis, an NLR≥2.94 was independently associated with poorer PFS[hazard ratio(HR)=1.58;95% confidence interval(95% CI): 1.01-2.49, P=0.046] and OS(HR=1.77;95% CI:1.04-3.04, P=0.036). While m MDSC counts did not significantly change following two cycles of therapy(P=0.530),g MDSC counts decreased significantly after two treatment cycles(P=0.025) but tended to increase in patients with progressive disease after two treatment cycles(P=0.098). A progressive increase in g MDSC counts(≥44%) was associated with a significantly shorter PFS and OS vs. a g MDSC count increase <44%(P=0.001 and P=0.003,respectively).Conclusions: The baseline NLR may help guide clinical decisions during ramucirumab plus paclitaxel therapy for gastric cancer. Our g MDSC kinetics data warrant further clinical validation and mechanistic investigation.展开更多

Neutrophil-to-lymphocyte ratio(NLR) is a marker of inflammation reflecting the progress of many diseases. However, whether NLR at admission can predict the occurrence of AKI after surgery in the intensive care unit(ICU) remains unknown.AIM To clarify the relationship between NLR and the occurrence of AKI in patients with gastrointestinal and hepatobiliary surgery in the ICU.METHODS A retrospective analysis of 282 patients receiving surgical ICU care after gastrointestinal and hepatobiliary surgery in our hospital from December 2014 to December 2018 was performed.RESULTS Postoperative AKI occurred in 84 patients(29.79%) in this cohort. NLR by the multivariate analysis was an independent risk factor for occurrence of postoperative AKI in patients with gastrointestinal and hepatobiliary surgery in the ICU. In this cohort, receiver operating characteristic curves of AKI occurrence showed that the optimal cut-off value of NLR was 8.380. NLR was found to be significantly correlated with the white blood cell count, neutrophil count, lymphocyte count, arterial lactate and dialysis(P < 0.05). Additionally, NLR value at admission was higher in AKI patients compared with the non-AKI patients and increased with the severity of AKI. Patients with NLR ≥ 8.380 exhibited significantly higher incidences of postoperative AKI and severe AKI than patients with NLR < 8.380(AKI: 38.12% vs 14.85%, P < 0.001;severe AKI: 14.36% vs 1.98%, P = 0.001).CONCLUSION NLR at admission is a predictor of AKI occurrence in patients with gastrointestinal and hepatobiliary surgery in ICU. NLR should be included in the routine assessment of AKI occurrence.展开更多

All of the original articles were evaluated according to date of publications, countries, clinics and topics. Studies about occlusive vascular diseases were evaluated according to their qualifications, review methods and results. SPSS for Windows 16.0 was used in data analysis and data were expressed as mean, standard deviation and percentage.RESULTS: A total of 735 original research articles were investigated. The number of publications have shown a regular logarithmic increase over the years. Thirty-two percent of all publications were performed by clinics in Turkey and 56.4% were performed by general-oncological surgery and cardiology clinics. A total of 107 publications were identified to be about occlusive vascular diseases, 80.3% of these publications were found to be prognostic and 19.6% to be diagnostic, 82.2% of them were found to be planned as retrospective and 17.7% as prospective. In 95.3% of prognostic publications, there was a positive correlation between high NLR values at admission and poor prognosis. In 95.3% of diagnostic publications high NLR values at admission were identifi ed to be signifi cant diagnostically.CONCLUSION: Elevated neutrophil-to-lymphocyte ratio at admission, could be used as a diagnostic and/or prognostic parameter in occlusive vascular diseases.展开更多

Methods This retrospective study included 321 patients with HCC who underwent resection. The NLR was calculated using the neutrophil and lymphocyte counts in routine preoperative blood tests. Receiver operating characteristic curve analysis was performed to select the most appropriate NLR cutoff value. The preoperative NLR, patient demographics, and clinical and pathological data, including disease-free survival （DFS） and overall survival （OS）, were analyzed. Results The NLR was correlated with alpha-fetoprotein levels （X2 = 5.876, P = 0.015）, tumor size （X2 = 32.046, P 〈 0.001）, portal vein tumor thrombus （PVTT; x2 = 4.930, P = 0.026）, tumor encapsulation （x2 = 7.243, P = 0.007）, and recurrence （x2 = 7.717, P = 0.005）. Multivariate analyses illustrated that the number of tumors, PVTT, tumor size, and the NLR were independent factors for predicting DFS and OS. in patients with HCC and cirrhosis, but not among those without cirrhosis, a larger NLR predicted poorer postoperative DFS and OS （both P 〈 0.001）. Conclusion As a simple, effective independent predictor for patients with HCC, the preoperative NLR plays an important role in accurately predicting the postoperative outcomes of patients with HCC and cir- rhosis, but not those of patients without cirrhosis.展开更多

文摘Objective: To analyze data available in the literature regarding a possible prognostic value of the platelet-to-lymphocyte ratio (PLR) and neutrophil-to-lymphocyte ratio (NLR) in prostate cancer (PCa) patients stratified in non-metastatic and metastatic diseases.Methods: A literature search process was performed following the Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines. In our meta-analysis, the pooled event rate estimated and the pooled hazard ratio were calculated using a random effect model.Results: Forty-two articles were selected for our analysis. The pooled risk difference for non-organ confined PCa between high and low NLR cases was 0.06 (95% confidence interval [CI]: −0.03-0.15) and between high and low PLR cases increased to 0.30 (95% CI: 0.16-0.43). In non-metastatic PCa cases, the pooled hazard ratio for overall mortality between high and low NLR was 1.33 (95% CI: 0.78-1.88) and between high and low PLR was 1.47 (95% CI: 0.91-2.03), whereas in metastatic PCa cases, between high and low NLR was 1.79 (95% CI: 1.44-2.13) and between high and low PLR was 1.05 (95% CI: 0.87-1.24).Conclusion: The prognostic values of NLR and PLR in terms of PCa characteristics and responses after treatment show a high level of heterogeneity of results among studies. These two ratios can represent the inflammatory and immunity status of the patient related to several conditions. A higher predictive value is related to a high NLR in terms of risk for overall mortality in metastatic PCa cases under systemic treatments.

文摘BACKGROUND In recent studies,accumulating evidence has revealed a strong association between the inflammatory response and the prognosis of many tumors.There is a certain correlation of neutrophil-to-lymphocyte ratio(NLR)with the prognosis in gastric cancer(GC)patients undergoing neoadjuvant chemotherapy(NAC).However,the existing research results have remained controversial.AIM To explore the relationship between NLR ratio and prognosis of GC patients receiving NAC.METHODS A thorough systematic search was performed in databases such as PubMed,Embase,Web of Science,and Cochrane Library,the search is available until February 29,2024,and studies exploring the interaction of NLR with clinical outcomes were collected.Relevant studies meeting pre-defined inclusion and exclusion criteria were carefully chosen.The outcomes included progression-free survival(PFS),relapse-free survival,disease-free survival(DFS),and overall survival(OS).The hazard ratio(HR)and its corresponding 95%confidence interval(CI)were utilized for estimation.RESULTS Our analysis encompassed 852 patients and incorporated data from 12 cohort studies.The comprehensive analysis revealed a significant association of high NLR with reduced OS(HR=1.76;95%CI:1.22-2.54,P=0.003),relapsefree survival(HR=3.73;95%CI:1.74-7.96,P=0.0007),and PFS(HR=2.32;95%CI:1.42-3.81,P=0.0008)in patients.However,this correlation in disease-free survival was not significant.NLR demonstrated its crucial role in effectively predicting the OS of GC patients undergoing NAC at different detection times,ages,regions,and NLR thresholds.CONCLUSION In GC patients receiving NAC,an elevated NLR is strongly associated with reduced OS and PFS.NLR has become an effective biomarker for patient prognosis evaluation,providing valuable insights for the treatment strategies of NAC in GC patients.
文摘We conducted a comprehensive review of existing prediction models pertaining to the efficacy of immune-checkpoint inhibitor(ICI)and the occurrence of immune-related adverse events(irAEs).The predictive potential of neutrophil-to-lymphocyte ratio(NLR)and platelet-to-lymphocyte ratio(PLR)in determining ICI effectiveness has been extensively investigated,while limited research has been conducted on predicting irAEs.Furthermore,the combined model incor-porating NLR and PLR,either with each other or in conjunction with additional markers such as carcinoembryonic antigen,exhibits superior predictive capabilities compared to individual markers alone.NLR and PLR are promising markers for clinical applications.Forthcoming models ought to incorporate established efficacious models and newly identified ones,thereby constituting a multifactor composite model.Furthermore,efforts should be made to explore effective clinical application approaches that enhance the predictive accuracy and efficiency.

文摘BACKGROUND Type 2 diabetes mellitus(T2DM)is a leading risk factor for the development and progression of chronic kidney disease(CKD).However,an accurate and con-venient marker for early detection and appropriate management of CKD in in-dividuals with T2DM is limited.Recent studies have demonstrated a strong correlation between the neutrophil-to-lymphocyte ratio(NLR)and CKD.None-theless,the predictive value of NLR for renal damage in type 2 diabetic patients remains understudied.This study included 1040 adults aged 65 or older with T2DM from Shanghai's Community Health Service Center.The total number of neutrophils and lym-phocytes was detected,and NLR levels were calculated.CKD was defined as an estimated glomerular filtration rate≤60 mL/min/1.73 m².Participants were di-vided into four groups based on NLR levels.The clinical data and biochemical characteristics were compared among groups.A multivariate logistic regression model was used to analyze the association between NLR levels and CKD.RESULTS Significant differences were found in terms of sex,serum creatinine,blood urea nitrogen,total cholesterol,and low-density lipoprotein cholesterol among patients with T2DM in different NLR groups(P<0.0007).T2DM patients in the highest NLR quartile had a higher prevalence of CKD(P for trend=0.0011).Multivariate logistic regression analysis indicated that a high NLR was an independent risk factor for CKD in T2DM patients even after adjustment for important clinical and pathological parameters(P=0.0001,odds ratio=1.41,95%confidence intervals:1.18-1.68).CONCLUSION An elevated NLR in patients with T2DM is associated with higher prevalence of CKD,suggesting that it could be a marker for the detection and evaluation of diabetic kidney disease.

文摘BACKGROUND Acute liver failure(ALF)is a common cause of postoperative death in patients with hepatocellular carcinoma(HCC)and is a serious threat to patient safety.The neutrophil-to-lymphocyte ratio(NLR)is a common inflammatory indicator that is associated with the prognosis of various diseases,and the albumin-bilirubin score(ALBI)is used to evaluate liver function in liver cancer patients.Therefore,this study aimed to construct a predictive model for postoperative ALF in HCC tumor integrity resection(R0)based on the NLR and ALBI,providing a basis for clinicians to choose appropriate treatment plans.AIM To construct an ALF prediction model after R0 surgery for HCC based on NLR and ALBI.METHODS In total,194 patients with HCC who visited The First People’s Hospital of Lianyungang to receive R0 between May 2018 and May 2023 were enrolled and divided into the ALF and non-ALF groups.We compared differences in the NLR and ALBI between the two groups.The risk factors of ALF after R0 surgery for HCC were screened in the univariate analysis.Independent risk factors were analyzed by multifactorial logistic regression.We then constructed a prediction model of ALF after R0 surgery for HCC.A receiver operating characteristic curve,calibration curve,and decision curve analysis(DCA)were used to evaluate the value of the prediction model.RESULTS Among 194 patients with HCC who met the standard inclusion criteria,46 cases of ALF occurred after R0(23.71%).There were significant differences in the NLR and ALBI between the two groups(P<0.05).The univariate analysis showed that alpha-fetoprotein(AFP)and blood loss volume(BLV)were significantly higher in the ALF group compared with the non-ALF group(P<0.05).The multifactorial analysis showed that NLR,ALBI,AFP,and BLV were independent risk factors for ALF after R0 surgery in HCC.The predictive efficacy of NLR,ALBI,AFP,and BLV in predicting the occurrence of ALT after R0 surgery for HCC was average[area under the curve(AUC)NLR=0.767,AUCALBI=0.755,AUCAFP=0.599,AUCBLV=0.718].The prediction model for ALF after R0 surgery for HCC based on NLR and ALBI had a better predictive efficacy(AUC=0.916).The calibration curve and actual curve were in good agreement.DCA showed a high net gain and that the model was safer compared to the curve in the extreme case over a wide range of thresholds.CONCLUSION The prediction model based on NLR and ALBI can effectively predict the risk of developing ALF after HCC R0 surgery,providing a basis for clinical prevention of developing ALF after HCC R0 surgery.

文摘BACKGROUND The neutrophil-to-lymphocyte ratio(NLR),a composite inflammatory biomarker,is associated with the prognosis in patients with colorectal tumors.However,whether the NLR can be used as a predictor of symptomatic postoperative ana-stomotic leakage(AL)in elderly patients with colon cancer is unclear.AIM To assess the role of the NLR in predicting the occurrence of symptomatic AL after surgery in elderly patients with colon cancer.METHODS Data from elderly colon cancer patients who underwent elective radical colectomy with anastomosis at three centers between 2018 and 2022 were retrospectively analyzed.Receiver operating characteristic curve analysis was performed to determine the best predictive cutoff value for the NLR.Twenty-two covariates were matched using a 1:1 propensity score matching method,and univariate and multivariate logistic regression analyses were used to determine risk factors for the development of postoperative AL.RESULTS Of the 577 patients included,36(6.2%)had symptomatic AL.The optimal cutoff value of the NLR for predicting AL was 2.66.After propensity score matching,the incidence of AL was significantly greater in the≥2.66 NLR subgroup than in the<2.66 NLR subgroup(11.5%vs 2.5%;P=0.012).Univariate logistic regression analysis revealed statistically significant correlations between blood transfusion intraoperatively and within 2 d postoper-atively,preoperative albumin concentration,preoperative prognostic nutritional index,and preoperative NLR and AL occurrence(P<0.05);multivariate logistic regression analysis revealed that an NLR≥2.66[odds ratio(OR)=5.51;95%confidence interval(CI):1.50-20.26;P=0.010]and blood transfusion intraoperatively and within 2 d postoperatively(OR=2.52;95%CI:0.88-7.25;P=0.049)were risk factors for the occurrence of symptomatic AL.CONCLUSION A preoperative NLR≥2.66 and blood transfusion intraoperatively and within 2 d postoperatively are associated with a higher incidence of postoperative symptomatic AL in elderly patients with colon cancer.The preoperative NLR has predictive value for postoperative symptomatic AL after elective surgery in elderly patients with colon cancer.
文摘Background The neutrophil-to-lymphocyte （N/L） ratio has been associated with poor prognosis in patients with heart failure, but it has not been compared with N-terminal pro-brain natriuretic peptide （NT-proBNP） in elderly patients with chronic heart failure （CHF）. We sought to make this comparison. Methods A total of 1355 elderly patients with CHF were analyzed. A multivariate logistic regression model was used to analyze the variables associated with atrial fibrillation （AF）. Cox regression analysis was used to assess the multivariable rela- tionship between the N/L ratio, NT-proBNP level, and subsequent major cardiovascular events （MCE）. Results In the multiple logistic regression analysis, the N/L ratio was demonstrated as a risk factor for AF in elderly patients with CHF [odds ratio （OR）： 1.079, 95% confi- dence interval （CI）： 1.027-1.134, P = 0.003]. The median follow-up period was 18 months. In a multivariable model using tertiles of both variables, the highest tertile of the N/L ratio was significantly associated with MCE [hazard ratio （HR）： 1.407, 95% CI： 1.098-1.802, P = 0.007] compared with the lowest tertile. Similarly, the highest NT-proBNP tertile was also significantly associated with MCE （HR： 1.461, 95% CI： 1.104-1.934, P- 0.008）. Conclusions In elderly patients with CHF, the N/L ratio is one of the important risk factors for AF and it is an inexpensive and readily available marker with similar independent prognostic power to NT-proBNP. The risk of MCE increases 1.407-fold when the N/L ratio is elevated to the highest tertile.
文摘AIM: To summarize the results of studies investigating neutrophil-to-lymphocyte ratio(NLR) and to identify the role of NLR in ocular diseases. METHODS: With the aim of identifying the studies related to NLR, a search was conducted on http://www.ncbi.nlm.nih.gov/pubmed by utilizing the key words "neutrophil lymphocyte ratio, ocular diseases, and eye diseases" up to February 2018. All of the original articles were assessed according to date of publications, countries, clinics and topics. Studies about ocular inflammatory diseases were evaluated according to their qualifications, review methods and results. RESULTS: A total of 4473 publications, including original research articles and reviews were screened. The number of publications was shown a regular logarithmic increase over the years. The majority of studies were performed by clinics in Turkey and many of these publications were performed by oncology and cardiology clinics. A total of 75 publications were identified to be about ocular diseases. CONCLUSION: Elevated NLR as a cheap, reproducible, and readily available marker could be used as a diagnostic and/or prognostic marker in ocular diseases.
文摘AIM To investigate whether the preoperative neutrophil-tolymphocyte ratio(NLR) could predict the prognosis of hepatocellular carcinoma(HCC) patients with portal/hepatic vein tumor thrombosis(PVTT/HVTT) after hepatectomy.METHODS The study population included 81 HCC patients who underwent hepatectomy and were diagnosed with PVTT/HVTT based on pathological examination. The demographics, laboratory analyses, and histopathology data were analyzed.RESULTS Overall survival(OS) and disease-free survival(DFS) were determined in the patients with a high(> 2.9) and low(≤ 2.9) NLR. The median OS and DFS duration in the high NLR group were significantly shorter than those in the low NLR group(OS: 6.2 mo vs 15.7 mo, respectively, P = 0.007; DFS: 2.2 mo vs 3.7 mo, respectively, P = 0.039). An NLR > 2.9 was identified as an independent predictor of a poor prognosis of OS(P = 0.034, HR = 1.866; 95%CI: 1.048-3.322) in uni-and multivariate analyses. Moreover, there was a significantly positive correlation between the NLR and the Child-Pugh score(r = 0.276, P = 0.015) and the maximum diameter of the tumor(r = 0.435, P < 0.001). Additionally, the NLR could enhance the prognostic predictive power of the CLIP score for DFS in these patients. CONCLUSION The preoperative NLR is a prognostic predictor after hepatectomy for HCC patients with PVTT/HVTT. NLR > 2.9 indicates poorer OS and DFS.
文摘Objective: We aimed to investigate the prognostic value of neutrophil-to-lymphocyte ratio(NLR) and myeloidderived suppressor cells(MDSCs) in gastric cancer patients treated with second-line ramucirumab plus paclitaxel.Methods: A total of 116 patients with advanced or metastatic gastric cancer who receive ramucirumab plus paclitaxel were prospectively enrolled. Fresh blood samples were collected before and after treatment, and flow cytometry was performed to assess the proportions of monocytic(m MDSCs) and granulocytic MDSCs(g MDSCs).Results: Median age was 58 years and 71(61.2%) patients were male. A baseline NLR≥2.94 was associated with significantly poorer progression-free survival(PFS) and overall survival(OS) vs. an NLR<2.94(P=0.011 and P=0.002, respectively). In multivariate analysis, an NLR≥2.94 was independently associated with poorer PFS[hazard ratio(HR)=1.58;95% confidence interval(95% CI): 1.01-2.49, P=0.046] and OS(HR=1.77;95% CI:1.04-3.04, P=0.036). While m MDSC counts did not significantly change following two cycles of therapy(P=0.530),g MDSC counts decreased significantly after two treatment cycles(P=0.025) but tended to increase in patients with progressive disease after two treatment cycles(P=0.098). A progressive increase in g MDSC counts(≥44%) was associated with a significantly shorter PFS and OS vs. a g MDSC count increase <44%(P=0.001 and P=0.003,respectively).Conclusions: The baseline NLR may help guide clinical decisions during ramucirumab plus paclitaxel therapy for gastric cancer. Our g MDSC kinetics data warrant further clinical validation and mechanistic investigation.

文摘BACKGROUND Postoperative acute kidney injury(AKI) is a complex pathological process involved intrarenal and systemic inflammation caused by renal hypoperfusion, nephrotoxic drugs and urinary obstruction. Neutrophil-to-lymphocyte ratio(NLR) is a marker of inflammation reflecting the progress of many diseases. However, whether NLR at admission can predict the occurrence of AKI after surgery in the intensive care unit(ICU) remains unknown.AIM To clarify the relationship between NLR and the occurrence of AKI in patients with gastrointestinal and hepatobiliary surgery in the ICU.METHODS A retrospective analysis of 282 patients receiving surgical ICU care after gastrointestinal and hepatobiliary surgery in our hospital from December 2014 to December 2018 was performed.RESULTS Postoperative AKI occurred in 84 patients(29.79%) in this cohort. NLR by the multivariate analysis was an independent risk factor for occurrence of postoperative AKI in patients with gastrointestinal and hepatobiliary surgery in the ICU. In this cohort, receiver operating characteristic curves of AKI occurrence showed that the optimal cut-off value of NLR was 8.380. NLR was found to be significantly correlated with the white blood cell count, neutrophil count, lymphocyte count, arterial lactate and dialysis(P < 0.05). Additionally, NLR value at admission was higher in AKI patients compared with the non-AKI patients and increased with the severity of AKI. Patients with NLR ≥ 8.380 exhibited significantly higher incidences of postoperative AKI and severe AKI than patients with NLR < 8.380(AKI: 38.12% vs 14.85%, P < 0.001;severe AKI: 14.36% vs 1.98%, P = 0.001).CONCLUSION NLR at admission is a predictor of AKI occurrence in patients with gastrointestinal and hepatobiliary surgery in ICU. NLR should be included in the routine assessment of AKI occurrence.

In 95.3% of prognostic publications, there was a positive correlation between high NLR values at admission and poor prognosis. In 95.3% of diagnostic publications high NLR values at admission were identifi ed to be signifi cant diagnostically.CONCLUSION: Elevated neutrophil-to-lymphocyte ratio at admission, could be used as a diagnostic and/or prognostic parameter in occlusive vascular diseases.
文摘BACKGROUND Low neutrophil-to-lymphocyte ratio(NLR)has been shown to be associated with a favorable therapeutic response to nivolumab.The activation of immunocompetent cells such as lymphocytes exhibits an antitumor effect;however,the development of excessive immune responses in autologous organs along with the breakdown of self-tolerance causes immune-related adverse events,including hypothyroidism.Therefore,the possibility that NLR is associated with immune response shows that NLR can be not only a predictive factor for good response to nivolumab but also a predictive factor for the development of hypothyroidism.AIM To evaluate whether continuous NLR monitoring during nivolumab treatment is useful for predicting the incidence and onset period of hypothyroidism.METHODS This retrospective study comprised patients who received nivolumab for treating all types of cancer at our hospital between January 2015 and December 2019.The NLRs of patients were measured before each administration,and the patients were followed up till the administration of 12 doses.NLR at treatment initiation was compared between patients with and without hypothyroidism.Patients who developed hypothyroidism were categorized into three groups:those with NLR<3.5,3.5 to<5,and≥5 according to their maximum NLR from treatment initiation to hypothyroidism development.Further,the onset periods of hypothyroidism were compared between the groups.RESULTS Overall,104 patients were included in the analysis.Twenty-one patients developed hypothyroidism throughout the observation period.NLR at treatment initiation was significantly lower(2.54±1.21 vs 4.58±4.03;P=0.017)in patients with hypothyroidism than in those without hypothyroidism,and patients with NLR<5 had a significantly higher incidence of hypothyroidism than those with NLR≥5(26%:20 of 78 patients vs 4%:1 of 26 patients;P=0.022).Additionally,treatment continuity in patients with hypothyroidism was significantly longer than in those without hypothyroidism(median not reached vs 7 times administration,P=0.010).Patients with maximum NLR<3.5 until the development of hypothyroidism had a significantly earlier onset of hypothyroidism than those with maximum NLR≥5(hazard ratio for low tertile[NLR<3.5]vs high tertile[NLR≥5]:5.33,P=0.011).CONCLUSION Low NLR at treatment initiation increases the incidence of treatment-induced hypothyroidism.Furthermore,its persistence may be a risk factor for the early onset of hypothyroidism.

文摘Objective The aim of the study was to investigate the prognostic value of the preoperative peripheral neutrophil-to-lymphocyte ratio （NLR） in patients with hepatocellular cancer （HCC） and cirrhosis after hepa- tectomy. Methods This retrospective study included 321 patients with HCC who underwent resection. The NLR was calculated using the neutrophil and lymphocyte counts in routine preoperative blood tests. Receiver operating characteristic curve analysis was performed to select the most appropriate NLR cutoff value. The preoperative NLR, patient demographics, and clinical and pathological data, including disease-free survival （DFS） and overall survival （OS）, were analyzed. Results The NLR was correlated with alpha-fetoprotein levels （X2 = 5.876, P = 0.015）, tumor size （X2 = 32.046, P 〈 0.001）, portal vein tumor thrombus （PVTT; x2 = 4.930, P = 0.026）, tumor encapsulation （x2 = 7.243, P = 0.007）, and recurrence （x2 = 7.717, P = 0.005）. Multivariate analyses illustrated that the number of tumors, PVTT, tumor size, and the NLR were independent factors for predicting DFS and OS. in patients with HCC and cirrhosis, but not among those without cirrhosis, a larger NLR predicted poorer postoperative DFS and OS （both P 〈 0.001）. Conclusion As a simple, effective independent predictor for patients with HCC, the preoperative NLR plays an important role in accurately predicting the postoperative outcomes of patients with HCC and cir- rhosis, but not those of patients without cirrhosis.

文摘Objective The association between neutrophil-to-lymphocyte ratio(NLR)with subclinical macrovascular and microvascular diseases has been less investigated.We sought to examine the association between NLR and new-onset subclinical macrovascular and microvascular abnormalities in the Chinese population.Methods From a community cohort,we included 6,430 adults aged≥40 years without subclinical macrovascular and microvascular diseases at baseline.We measured subclinical macrovascular and microvascular abnormalities separately using the ankle-brachial index(ABI),brachial-ankle pulse wave velocity(baPWV),and albuminuria.Results During a mean follow-up of 4.3 years,110 participants developed incident abnormal ABI,746 participants developed incident elevated baPWV,and 503 participants developed incident albuminuria.Poisson regression analysis indicated that NLR was significantly associated with an increased risk of newonset abnormal ABI,elevated baPWV,and albuminuria.Compared to overweight/obese participants,we found a much stronger association between NLR and subclinical vascular abnormalities in participants with normal weight.Furthermore,we found an interaction between the NLR and body mass index(BMI)on the risk of new-onset abnormal ABI(P for interaction:0.01).Conclusion NLR was associated with subclinical macrovascular and microvascular diseases in the Chinese population.Furthermore,in participants with normal weight,the association between NLR and subclinical vascular abnormalities was much stronger.
