Systemic immune-inflammation index,neutrophilto-lymphocyte ratio,and platelet-to-lymphocyte ratio in patients with type 2 diabetes at different stages of diabetic retinopathy

AIM:To investigate systemic immune-inflammation index(SII),neutrophil-to-lymphocyte ratio(NLR),and plateletto-lymphocyte ratio(PLR)levels in patients with type 2 diabetes at different stages of diabetic retinopathy(DR).METHODS:This retrospective study included 141 patients with type 2 diabetes mellitus(DM):45 without diabetic retinopathy(NDR),47 with non-proliferative diabetic retinopathy(NPDR),and 49 with proliferative diabetic retinopathy(PDR).Complete blood counts were obtained,and NLR,PLR,and SII were calculated.The study analysed the ability of inflammatory markers to predict DR using receiver operating characteristic(ROC)curves.The relationships between DR stages and SII,PLR,and NLP were assessed using multivariate logistic regression.RESULTS:The average NLR,PLR,and SII were higher in the PDR group than in the NPDR group(P=0.011,0.043,0.009,respectively);higher in the NPDR group than in the NDR group(P<0.001 for all);and higher in the PDR group than in the NDR group(P<0.001 for all).In the ROC curve analysis,the NLR,PLR,and SII were significant predictors of DR(P<0.001 for all).The highest area under the curve(AUC)was for the PLR(0.929 for PLR,0.925 for SII,and 0.821 for NLR).Multivariate regression analysis indicated that NLR,PLR,and SII were statistically significantly positive and independent predictors for the DR stages in patients with DM[odds ratio(OR)=1.122,95%confidence interval(CI):0.200–2.043,P<0.05;OR=0.038,95%CI:0.018–0.058,P<0.05;OR=0.007,95%CI:0.001–0.01,P<0.05,respectively).CONCLUSION:The NLR,PLR,and SII may be used as predictors of DR.

Systemic immune-inflammation index combined with pediatric appendicitis score in assessing the severity and prognosis for paediatric appendicitis

BACKGROUND Pediatric appendicitis is a common cause of abdominal pain in children and is recognized as a significant surgical emergency.A prompt and accurate diagnosis is essential to prevent complications such as perforation and peritonitis.AIM To investigate the predictive value of the systemic immune-inflammation index(SII)combined with the pediatric appendicitis score(PAS)for the assessment of disease severity and surgical outcomes in children aged 5 years and older with appendicitis.METHODS Clinical data of 104 children diagnosed with acute appendicitis were analyzed.The participants were categorized into the acute appendicitis group and chronic appendicitis group based on disease presentation and further stratified into the good prognosis group and poor prognosis group based on prognosis.The SII and PAS were measured,and a joint model using the combined SII and PAS was constructed to predict disease severity and surgical outcomes.RESULTS Significant differences were observed in the SII and PAS parameters between the acute appendicitis group and chronic appendicitis group.Correlation analysis showed associations among the SII,PAS,and disease severity,with the combined SII and PAS model demonstrating significant predictive value for assessing disease severity[aera under the curve(AUC)=0.914]and predicting surgical outcomes(AUC=0.857)in children aged 5 years and older with appendicitis.CONCLUSION The study findings support the potential of integrating the SII with the PAS for assessing disease severity and predicting surgical outcomes in pediatric appendicitis,indicating the clinical utility of the combined SII and PAS model in guiding clinical decision-making and optimizing surgical management strategies for pediatric patients with appendicitis.

Systemic immune-inflammation index for predicting prognosis of colorectal cancer

AIM To investigate the clinical significance of preoperative systemic immune-inflammation index(SII) in patients with colorectal cancer(CRC). METHODS A retrospective analysis of 1383 cases with CRC was performed following radical surgery. SII was calculated with the formula SII =(P × N)/L, where P, N, and L refer to peripheral platelet, neutrophil, and lymphocyte counts, respectively. The clinicopathological features and follow-up data were evaluated to compare SII with other systemic inflammation-based prognostic indices such as the neutrophil-lymphocyte ratio(NLR) and platelet-lymphocyte ratio(PLR) in patients with CRC.RESULTS The optimal cut-off point for SII was defined as 340. The overall survival(OS) and disease-free survival(DFS) were better in patients with low NLR, PLR, and SII(P < 0.05). The SII was an independent predictor of OS and DFS in multivariate analysis. The area under the receiver-operating characteristics(ROC) curve for SII(0.707) was larger than those for NLR(0.602) and PLR(0.566). In contrast to NLR and PLR, SII could effectively discriminate between the TNM subgroups. CONCLUSION SII is a more powerful tool for predicting survival outcome in patients with CRC. It might assist the identification of high-risk patients among patients with the same TNM stage.

Prognostic significance of systemic immune-inflammation index in patients with intrahepatic cholangiocarcinoma undergoing hepatic resection

BACKGROUND The prognosis of intrahepatic cholangiocarcinoma(ICC)patients following surgical resection remains poor.It is necessary to investigate effective biomarkers or prognostic models for ICC patients.AIM To investigate the prognostic effect of systemic immune-inflammation index(SII)to predict long-term outcomes in ICC patients with undergoing hepatic resection.METHODS Consecutive ICC patients who underwent initial hepatectomy with curative intent from January 2009 to September 2017 were retrospectively reviewed.Receiver-operating characteristic(ROC)curves were used to determine the optimal cut-off values of SII.Kaplan-Meier curves and Cox proportional hazards regression were performed to evaluate the discriminative ability of preoperative SII in predicting overall survival(OS)and recurrence-free survival(RFS).RESULTS A total of 530 patients were included and randomly divided into derivation(n=265)and validation cohort(n=265).The optimal cut-off value for SII was 450.Ata median follow-up of 18 mo(range,1-115.4 mo),317(59.8%)patients died and381(71.9%)patients experienced tumor relapse.Low SII level was associated with better OS and RFS(both P<0.05).Multivariate analyses identified multiple tumors,node invasion and high SII level as independent risk factors for OS,while multiple tumors,node invasion and high SII level were identified as independent risk factors for RFS.Validation cohort confirmed the findings of derivation cohort.CONCLUSION The present study demonstrated the feasibility of preoperative SII as a prognostic indicator for ICC.Patients with increased SII level were associated with worse OS and earlier tumor recurrence.Elevated SII level was an independent risk factor for OS and RFS in patients with ICC after hepatectomy.In the future,the SII could help stratifying patients with ICC,thus guiding therapeutic choices,especially in immunotherapy.

Pretreatment systemic immune-inflammation index predicts survival for non-metastatic nasopharyngeal carcinoma:two independent institutional studies

Objective:This study aimed to evaluate the prognostic value of the pretreatment systemic immune-inflammation index(SII)in non-metastatic nasopharyngeal carcinoma(NPC).Methods:We retrospectively analyzed the data of 839 patients with non-metastatic NPC recruited from two independent institutions.The training-set cohort and the external validation-set cohort was comprised of 459 and 380 patients from each institution,respectively.The optimal cut-offvalue of SII was determined,and a prognostic risk stratification model was developed based on the training cohort and further assessed in the validation cohort.The propensity score matching(PSM)method was applied to minimize the confounding effects of unbalanced covariables.Results:The optimal cut-offvalue of the SII in the training cohort was 686,which was confirmed using the vali-dation cohort.Multivariate analysis showed that both before and after PSM,SII values>686 were independently associated with worse progression-free survival(PFS)ratio in both cohorts(before PSM,P=0.008 and P=0.008;after PSM,P=0.008 and P=0.007,respectively).Based on the analysis of independent prognostic factors of SII and N stage,we developed a categorical risk stratification model,which achieved significant discrimination among risk indexes associated with PFS and distant metastasis-free survival(DMFS)in the training cohort.There was no significant difference in PFS between RT alone and combined therapies within the low-and intermediate-risk groups(5-year PFS,77.5%vs.75.3%,P=0.275).Patients in the high-risk group who received concurrent chemoradiotherapy experienced superior PFS compared with those who received other therapies(5-year PFS,64.9%vs.40.3%,P=0.003).Conclusion:Pretreatment SII predicts PFS of patients with non-metastatic NPC.Prognostic risk stratification incorporating SII is instructive for selecting individualized treatment.

Actuality and underlying mechanisms of systemic immuneinflammation index and geriatric nutritional risk index prognostic value in hepatocellular carcinoma

This editorial contains comments on the article“Correlation between preoperative systemic immune inflammation index,nutritional risk index,and prognosis of radical resection of liver cancer”in a recent issue of the World Journal of Gastrointestinal Surgery.It pointed out the actuality and importance of the article and focused primarily on the underlying mechanisms making the systemic immuneinflammation index(SII)and geriatric nutritional risk index(GNRI)prediction features valuable.There are few publications on both SII and GNRI together in hepatocellular carcinoma(HCC)and patient prognosis after radical surgery.Neutrophils release cytokines,chemokines,and enzymes,degrade extracellular matrix,reduce cell adhesion,and create conditions for tumor cell invasion.Neutrophils promote the adhesion of tumor cells to endothelial cells,through physical anchoring.That results in the migration of tumor cells.Pro-angiogenic factors from platelets enhance tumor angiogenesis to meet tumor cell supply needs.Platelets can form a protective film on the surface of tumor cells.This allows avoiding blood flow damage as well as immune system attack.It also induces the epithelial-mesenchymal transformation of tumor cells that is critical for invasiveness.High SII is also associated with macro-and microvascular invasion and increased numbers of circulating tumor cells.A high GNRI was associated with significantly better progression-free and overall survival.HCC patients are a very special population that requires increased attention.SII and GNRI have significant survival prediction value in both palliative treatment and radical surgery settings.The underlying mechanisms of their possible predictive properties lie in the field of essential cancer features.Those features provide tumor nutrition,growth,and distribution throughout the body,such as vascular invasion.On the other hand,they are tied to the possibility of patients to resist tumor progression and development of complications in both postoperative and cancer-related settings.The article is of considerable interest.It would be helpful to continue the study follow-up to 2 years and longer.External validation of the data is needed.

Prognostic value of systemic immune.inflammation index in patients with gastric cancer

Background:Inflammation-based indexes have been used to predict survival and recurrence in cancer patients.Systemic immune-inflammation index(Sll) was reported to be associated with prognosis in some malignant tumors.In the present study,we aimed to explore the association between Sll and the prognosis of patients with gastric cancer.Methods:We retrospectively analyzed data from 444 gastric cancer patients who underwent gastrectomy at the First Affiliated Hospital of Sun Yat-sen University between January 1994 and December 2005.Preoperative Sll was calculated.The Chi square test or Fisher's exact test was used to determine the relationship between preoperative Sll and clinicopathologic characteristics.Overall survival(OS) rates were estimated using the Kaplan-Meier method,and the effect of Sll on OS was analyzed using the Cox proportional hazards model.Receiver operating characteristic(ROC)curves were used to compare the predictive ability of Sll,NLR,and PLR.Results:Sll equal to or higher than 660 was significantly associated with old age,large tumor size,unfavorable Borrmann classification,advanced tumor invasion,lymph node metastasis,distant metastasis,advanced TNM stage,and high carcino-embryonic antigen level,high neutrophil-lymphocyte ratio,and high platelet-lymphocyte ratio(all P<0.05).High Sll was significantly associated with unfavorable prognosis(P<0.001) and Sll was an independent predictor for OS(P=0.015).Subgroups analysis further showed significant associations between high Sll and short OS in stage Ⅰ,Ⅱ,Ⅲ subgroups(all P<0.05).Sll was superior to NLR and PLR for predicting OS in patients with gastric cancer.Conclusion:Preoperative Sll level is an independent prognostic factor for OS in patients with gastric cancer.

Effective immune-inflammation index for ulcerative colitis and activity assessments

BACKGROUND The inverse association between systemic immune-inammation index(SII)and overall survival in tumors has been studied.AIM To evaluate the hematological indexes for assessing the activity of ulcerative colitis(UC).METHODS In this case-control study,172 UC patients and healthy participants were included.Comparisons were made among groups of white blood cells,hemoglobin,platelets,neutrophils,lymphocytes,monocytes,SII,neutrophil-tolymphocyte ratio(NLR),and platelet-to-lymphocyte ratio(PLR).The relationship with hematological inflammation was verified by Spearman correlation analyses.The efficiency of SII,NLR,and PLR for distinguishing between UC and severe disease status was assessed by the receiver operator curve and logistic regression analyses.RESULTS The values of SII,NLR,and PLR were higher in UC patients than in controls(P<0.001)and were positively correlated with the Mayo endoscopic score,extent,Degree of Ulcerative Colitis Burden of Luminal Inflammation(DUBLIN)score,and Ulcerative Colitis Endoscopic Index of Severity(UCEIS).The cut-off NLR value of 562.22 predicted UC with a sensitivity of 79.65%and a specificity of 76.16%.Logistic regression analysis revealed that patients with SII and NLR levels above the median had a significantly higher risk of UC(P<0.05).Risk factors independently associated with DUBLIN≥3 included SII≥1776.80[odds ratio(OR)=11.53,P=0.027]and NLR value of 2.67-4.23(OR=2.96,P=0.047)on multivariate analysis.Compared with the first quartile,SII≥1776.80 was an independent predictor of UCEIS≥5(OR=18.46,P=0.012).CONCLUSION SII has a certain value in confirming UC and identifying its activity.

The Systemic Immune Inflammatory Index Predicts No-Reflow Phenomenon after Primary Percutaneous Coronary Intervention in Older Patients with STEMI

Purpose:Coronary no-reflow phenomenon(NRP),a common adverse complication in patients with ST-segment eleva-tion myocardial infarction(STEMI)treated by percutaneous coronary intervention(PCI),is associated with poor patient prognosis.In this study,the correlation between the systemic immune-inflammation index(SII)and NRP in older patients with STEMI was studied,to provide a basis for early identification of high-risk patients and improve their prognosis.Materials and methods:Between January 2017 and June 2020,578 older patients with acute STEMI admitted to the Department of Cardiology of Hebei General Hospital for direct PCI treatment were selected for this retrospective study.Patients were divided into an NRP group and normal-flow group according to whether NRP occurred during the operation.Clinical data and the examination indexes of the two groups were collected.Logistic regression was used to analyze the independent predictors of NRP,and the receiver operating characteristic curve was used to further analyze the ability of SII to predict NRP in older patients with STEMI.Results:Multivariate logistic analysis indicated that hypertension(OR=2.048,95%CI:1.252–3.352,P=0.004),lymphocyte count(OR=0.571,95%CI:0.368–0.885,P=0.012),platelet count(OR=1.009,95%CI:1.005–1.013,P<0.001),hemoglobin(OR=1.015,95%CI:1.003–1.028,P=0.018),multivessel disease(OR=2.237,95%CI:1.407–3.558,P=0.001),and SII≥1814(OR=3.799,95%CI:2.190–6.593,P<0.001)were independent predictors of NRP after primary PCI in older patients with STEMI.Receiver operating characteristic curve analysis demonstrated that SII had a high predictive value for NRP(AUC=0.738;95%CI:0.686–0.790),with the best cut-off value of 1814,a sensitivity of 52.85%and a specificity of 85.71%.Conclusion:For older patients with STEMI undergoing primary PCI,SII is a valid predictor of NRP.

Systemic immune-inflammation index:A predictor of major adverse cardiovascular events for patients with acute coronary syndrome

Background Systemic immune-inflammation index(SII)has emerged as a potential marker for assessing inflammation and predicting outcomes in patients with acute coronary syndrome(ACS).However,its role in forecasting clinical prognosis in ACS patients undergoing primary coronary angiography remains unclear.Methods This retrospective study included 657 ACS patients who underwent primary coronary angiography between January 2016 and January 2023.Patients were divided into low and high SII groups based on the Youden index cut-off value.The primary endpoint was the occurrence of major adverse cardiovascular events(MACEs),including nonfatal myocardial infarction(MI),nonfatal stroke,heart failure,target lesion revascularization(TLR),and cardiovascular death.Kaplan-Meier survival analysis and Cox regression were performed to assess the association between SII and outcomes.Results Patients with high SII had significantly higher rates of MACEs(25.7%vs.10.3%,P<0.001),including nonfatal MI,heart failure,and TLR.After adjusting for conventional risk factors,SII remained an independent predictor of MACEs(HR:2.102,95%CI:1.616-3.011,P=0.002).Kaplan-Meier analysis confirmed poorer event-free survival in the high SII group(P=0.00093).Conclusions Elevated SII was associated with a higher risk of adverse outcomes in ACS patients,suggesting its potential utility as a comprehensive tool for risk stratification and prognosis in ACS patients.[S Chin J Cardiol 2024;25(3):142-148]

目的·探讨全身免疫炎症指数(systemic immune inflammation index,SII)及躯体化症状评分(somatic symptom scale-China,SSS-CN)对首发急性心肌梗死(acute myocardial infarction,AMI)患者接受经皮冠状动脉介入治疗术(percutaneous coronary intervention,PCI)后发生院内主要不良心血管事件(major adverse cardiovascular event,MACE)的预测价值。方法·连续纳入2021年9月至2023年9月就诊于安徽省第二人民医院心内科并接受PCI治疗的首发AMI患者305例。根据患者住院期间是否发生MACE相关事件分为MACEs组(n=203)与非MACEs组(n=102)。对2组患者的性别、年龄、实验室检查结果等资料进行描述性统计分析,并根据分析结果对有统计学意义的项目进行二元Logistic回归检验;进一步绘制受试者操作特征(receiver operating characteristic,ROC)曲线,评估SII及SSS-CN预测院内MACE发生的价值。在此基础上联合冠状动脉syntax评分(syntax score,SS),评价三者联合的预测效能,根据最大约登指数确定诊断的最佳cut-off值。结果·共有203例患者发生MACE事件,其中179例(88.1%)患者发生心力衰竭,16例(7.9%)患者发生严重心律失常,4例(2.0%)患者发生休克,2例(1.0%)患者发生再发心肌梗死,2例(1.0%)患者死亡。与非MACE组相比,MACEs组SII及SSS-CN评分显著升高(1925.86 vs 934.23,38.57 vs 23.30;均P<0.05);二元Logistic回归分析结果提示两者均为MACE发生的独立危险因素。ROC曲线显示:当SII≥952时预测效能最佳,敏感度达64.0%,特异度达62.7%(AUC 0.675,95%CI 0.612~0.737);SSS-CN≥28.5分时预测效能最佳,敏感度达80.7%,特异度达77.5%(AUC 0.840,95%CI 0.794~0.886);联合SS后,三者对MACE的预测效能进一步提高(AUC 0.898,95%CI 0.862~0.933)。结论·首发AMI患者的入院SII及SSS-CN分值为此类患者行PCI术后住院期间发生MACE的独立危险因素,早期监测首发AMI患者PCI术后SII变化,或对有明显躯体化症状的患者及时进行SSS-CN评分能帮助识别院内MACE发生的高危患者。

Evaluation of preoperative blood markers for predicting intraabdominal infection during colorectal cancer resection:A commentary on recent findings

This commentary evaluates the study by Liu et al.This study investigates the predictive utility of the neutrophil-lymphocyte ratio,platelet-lymphocyte ratio,systemic immune-inflammation index,and carcinoembryonic antigen levels for post-operative intra-abdominal infection following colorectal cancer(CRC)surge-ry.The study highlights the critical need for analyzing diverse patient demogra-phics and delves into the potential impact of various confounding factors on the predictive accuracy of these markers.Additionally,the commentary advocates for the initiation of prospective studies aimed at validating and enhancing the clinical utility of these biomarkers in the context of CRC treatment.The commentary aims to underscore the importance of broadening the research framework to include a wider patient demographic and more comprehensive factor analyses,thereby enriching the predictive model's applicability and relevance in clinical settings.
