Systemic Inflammation Response Index and weight loss as prognostic factors in metastatic pancreatic cancer: A concept study from the PANTHEIA-SEOM trial

BACKGROUND The prognostic value of the Systemic Inflammation Response Index(SIRI)in advanced pancreatic cancer is recognized,but its correlation with patients´nutritional status and outcomes remains unexplored.AIM To study the prognostic significance of SIRI and weight loss in metastatic pancreatic cancer.METHODS The PANTHEIA-Spanish Society of Medical Oncology(SEOM)study is a multicentric(16 Spanish hospitals),observational,longitudinal,non-interventional initiative,promoted by the SEOM Real World-Evidence work group.This pilot study sought to analyze the association between weight loss and inflammatory status as defined by SIRI.The cohort stems from a proof-of-concept pilot study conducted at one of the coordinating centers.Patients with pathologically confirmed metastatic pancreatic adenocarcinoma,treated from January 2020 to January 2023,were included.The index was calculated using the product of neutrophil and monocyte counts,divided by lymphocyte counts,obtained within 15 days before initiation chemotherapy.This study evaluated associations between overall survival(OS),SIRI and weight loss.RESULTS A total of 50 patients were included.66%of these patients were male and the median age was 66 years.Metastasis sites:36%liver,12%peritoneal carcinomatosis,10%lung,and 42%multiple locations.Regarding the first line palliative chemotherapy treatments:50%received gemcitabine plus nab-paclitaxel;28%,modified fluorouracil,leucovorin,irinotecan and oxaliplatin,and 16%were administered gemcitabine.42%had a weight loss>5%in the three months(mo)preceding diagnosis.21 patients with a SIRI≥2.3×10^(3)/L exhibited a trend towards a lower median OS compared to those with a SIRI<2.3×10^(3)/L(4 vs 18 mo;P<0.000).Among 21 patients with>5%weight loss before diagnosis,the median OS was 6 mo,in contrast to 19 mo for those who did not experience such weight loss(P=0.003).Patients with a weight loss>5%showed higher SIRI levels.This difference was statistically significant(P<0.000).For patients with a SIRI<2.3×10^(3)/L,those who did not lose>5%of their weight had an OS of 20 mo,compared to 11 mo for those who did(P<0.001).No association was found between carbohydrate antigen 19-9 levels≥1000 U/mL and weight loss.CONCLUSION A higher SIRI was correlated with decreased survival rates in patients with metastatic pancreatic cancer and associated with weight loss.An elevated SIRI is suggested as a predictor of survival,emphasizing the need for prospective validation in the upcoming PANTHEIA-SEOM study.

Correlation between preoperative systemic immune inflammation index, nutritional risk index, and prognosis of radical resection of liver cancer

BACKGROUND Radical surgery is the most commonly used treatment for hepatocellular carcinoma(HCC).However,the surgical effect remains not ideal,and prognostic evaluation is insufficient.Furthermore,clinical intervention is rife with uncertainty and not conducive to prolonging patient survival.AIM To explore correlations between the systemic immune inflammatory index(SII)and geriatric nutritional risk index(GNRI)and HCC operation prognosis.METHODS This retrospective study included and collected follow up data from 100 HCC.Kaplan–Meier survival curves were used to analyze the correlation between SII and GNRI scores and survival.SII and GNRI were calculated as follows:SII=neutrophil count×platelet count/lymphocyte count;GNRI=[1.489×albumin(g/L)+41.7×actual weight/ideal weight].We analyzed the predictive efficacy of the SII and GNRI in HCC patients using receiver operating characteristic(ROC)curves,and the relationships between the SII,GNRI,and survival rate using Kaplan–Meier survival curves.Cox regression analysis was utilized to analyze independent risk factors influencing prognosis.RESULTS After 1 year of follow-up,24 patients died and 76 survived.The area under the curve(AUC),sensitivity,specificity,and the optimal cutoff value of SII were 0.728(95%confidence interval:0.600-0.856),79.2%,63.2%,and 309.14,respectively.According to ROC curve analysis results for predicting postoperative death in HCC patients,the AUC of SII and GNRI combination was higher than that of SII or GNRI alone,and SII was higher than that of GNRI(P<0.05).The proportion of advanced differentiated tumors,tumor maximum diameter(5–10 cm,>10 cm),lymph node metastasis,and TNM stage III-IV in patients with SII>309.14 was higher than that in patients with SII≤309.14(P<0.05).The proportion of patients aged>70 years was higher in patients with GNRI≤98 than that in patients with GNRI>98(P<0.05).The 1-year survival rate of the SII>309.14 group(compared with the SII≤309.14 group)and GNRI≤98 group(compared with the GNRI>98 group)was lower(P<0.05).CONCLUSION The prognosis after radical resection of HCC is related to the SII and GNRI and poor in high SII or low GNRI patients.

Influence of reduced-port laparoscopic surgery on perioperative indicators, postoperative recovery, and serum inflammation in patients with colorectal carcinoma

BACKGROUND Conventional five-port laparoscopic surgery,the current standard treatment for colorectal carcinoma(CRC),has many disadvantages.AIM To assess the influence of reduced-port laparoscopic surgery(RPLS)on perioperative indicators,postoperative recovery,and serum inflammation indexes in patients with CRC.METHODS The study included 115 patients with CRC admitted between December 2019 and May 2023,52 of whom underwent conventional five-port laparoscopic surgery(control group)and 63 of whom underwent RPLS(research group).Comparative analyses were performed on the following dimensions:Perioperative indicators[operation time(OT),incision length,intraoperative blood loss(IBL),and rate of conversion to laparotomy],postoperative recovery(first postoperative exhaust,bowel movement and oral food intake,and bowel sound recovery time),serum inflammation indexes[high-sensitivity C-reactive protein(hs-CRP),tumor necrosis factor-α(TNF-α),and interleukin-6(IL-6)],postoperative complications(anastomotic leakage,incisional infection,bleeding,ileus),and therapeutic efficacy.RESULTS The two groups had comparable OTs and IBL volumes.However,the research group had a smaller incision length;lower rates of conversion to laparotomy and postoperative total complication;and shorter time of first postoperative exhaust,bowel movement,oral food intake,and bowel sound recovery;all of which were significant.Furthermore,hs-CRP,IL-6,and TNF-αlevels in the research group were significantly lower than the baseline and those of the control group,and the total effective rate was higher.CONCLUSION RPLS exhibited significant therapeutic efficacy in CRC,resulting in a shorter incision length and a lower conversion rate to laparotomy,while also promoting postoperative recovery,effectively inhibiting the inflammatory response,and reducing the risk of postoperative complications.

Predictive Values of Postoperative and Dynamic Changes of Inflammation Indexes in Survival of Patients with Resected Colorectal Cancer

The aim of the present study was to evaluate the prognostic potential of postoperative scores of inflammation indexes and the dynamic changes of scores before and after tumor resection in colorectal cancer patients.The study included 516 colorectal cancer patients with primary colorectal tumor resection.Cox regression was applied to estimate the associations of postoperative and dynamic changes of inflammation indexes with progression-free survival and overall survival.As results,we found that higher postoperative neutrophil to lymphocyte ratio (NLR),neutrophil and monocyte to lymphocyte ratio (NMLR),platelet to lymphocyte ratio (PLR) and systemic immune inflammation index (SII)were associated with shorter progression-free survival.The increased NLR,NMLR,PLR,SII and C-reaction protein (CRP)to albumin (ALB) ratio (CAR)were associated with poor progression-free survival,with HRs (95% CIs)of 1.92 (1.27-2.90),1.46(1.11-2.09),2.10(1.34-3.30),1.81(1.22-2.70)and 1.65(1.03-2.67), respectively.Postoperative NMLR,SII,CAR,and their dynamic changes were also significantly correlated with overall survival,with the HRs (95% CIs)of 2.63(1.30-3.97), 2.44(1.43-4.17),2.74(1.31-5.74),2.08(1.21-3.60),1.97(1.12-3.45)and 2.55(1.21-5.38)respectively.In conclusion,postoperative inflammation indexes and their dynamic changes,particularly for NMLR,SII and CAR are promising prognostic predictors of CRC patients.

Association of systemic inflammation and body mass index with survival in patients with resectable gastric or gastroesophageal junction adenocarcinomas

Objective:The systemic inflammation index and body mass index(BMI)are easily accessible markers that can predict mortality.However,the prognostic value of the combined use of these two markers remains unclear.The goal of this study was therefore to evaluate the association of these markers with outcomes based on a large cohort of patients with gastric cancer.Methods:A total of 2,542 consecutive patients undergoing radical surgery for gastric or gastroesophageal junction adenocarcinoma between 2009 and 2014 were included.Systemic inflammation was quantified by the preoperative neutrophil-to-lymphocyte ratio(NLR).High systemic inflammation was defined as NLR≥3,and underweight was defined as BMI<18.5 kg/m2.Results:Among 2,542 patients,NLR≥3 and underweight were common[627(25%)and 349(14%),respectively].In the entire cohort,NLR≥3 or underweight independently predicted overall survival(OS)[hazard ratio(HR):1.236,95%confidence interval(95%CI):1.069–1.430;and HR:1.600,95%CI:1.350–1.897,respectively]and recurrence-free survival(RFS)(HR:1.230,95%CI:1.054–1.434;and HR:1.658,95%CI:1.389–1.979,respectively).Patients with both NLR≥3 and underweight(vs.neither)had much worse OS(HR:2.445,95%CI:1.853–3.225)and RFS(HR:2.405,95%CI:1.802–3.209).Furthermore,we observed similar results in subgroup analyses according to pathological stage,age,and postoperative chemotherapy.Conclusions:Our results showed that preoperative elevated NLR and decreased BMI had a significant negative effect on survival.Underweight combined with severe inflammation could enhance prognostication.Taking active therapeutic measures to reduce inflammation and increase nutrition may help improve outcomes.

Systemic immune inflammation index, ratio of lymphocytes to monocytes, lactate dehydrogenase and prognosis of diffuse large Bcell lymphoma patients

BACKGROUND In malignant tumors,inflammation plays a vital role in the development,invasion,and metastasis of cancer cells.Diffuse large B-cell lymphoma(DLBCL),the most common malignant proliferative disease of the lymphatic system,is commonly associated with inflammation.The international prognostic index(IPI),which includes age,lactate dehydrogenase(LDH),number of extranodal lesions,Ann Arbor score,and Eastern Cooperative Oncology Group(ECOG)score,can evaluate the prognosis of DLBCL.However,its use in accurately identifying highrisk patients and guiding treatment is poor.Therefore,it is important to find novel immune markers in predicting the prognosis of DLBCL patients.AIM To determine the association between the systemic immune inflammation index(SII),ratio of lymphocytes to monocytes(LMR),ratio of LMR to LDH(LMR/LDH),and prognosis of patients with DLBCL.METHODS A total of 68 patients diagnosed with DLBCL,treated in our hospital between January 2016 and January 2020,were included.χ2 test,Pearson’s R correlation,Kaplan Meier curves,and Cox proportional risk regression analysis were used.The differences in the SII,LMR,and LMR/LDH among patients with different clinicopathological features were analyzed.The differences in progression-free survival time among patients with different SII,LMR,and LMR/LDH expressions and influencing factors affecting the prognosis of DLBCL patients,were also analyzed.RESULTS The LMR and LMR/LDH in patients with Ann Arbor stage III–IV,ECOG score≥2,and SII,IPI score 2–5 were significantly higher than those of patients with Ann Arbor stage I-II and ECOG score<2(P<0.05).Patients with high SII,LMR,and LMR/LDH had progression-free survival times of 34 mo(95%CI:32.52–38.50),35 mo(95%CI:33.42–36.58)and 35 mo(95%CI:33.49–36.51),respectively,which were significantly lower than those with low SII,LMR,and LMR/LDH(P<0.05);the SII,LMR,and LMR/LDH were positively correlated(P<0.05).Cox proportional risk regression analysis showed that the SII,LMR,and LMR/LDH were influencing factors for the prognosis of DLBCL patients(hazard ratio=1.143,1.665,and 1.704,respectively;P<0.05).CONCLUSION The SII,LMR,and LMR/LDH are related to the clinicopathological features of DLCBL,and they also influence the prognosis of patients with the disease.

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.

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 impact of preoperative nutritional and immune inflammatory parameters on liver cancer

The immune response to tissue damage or infection involves inflammation,a multifaceted biological process distinguished by immune cell activation,mediator secretion,and immune cell recruitment to the site of injury.Several blood-based immune-inflammatory biomarkers with prognostic significance in malignancies have been identified.In this issue of the World Journal of Gastrointestinal Surgery,they examined the prognosis of liver cancer radical resection in relation to pre-operative systemic immune-inflammation and nutritional risk indices.Comparing older and younger individuals often reveals compromised nutritional and immu-nological statuses in the former.Therefore,performing preoperative evaluations of the nutritional status and immunity in geriatric patients is critical.In addition to being a primary treatment modality,radical resection is associated with a sig-nificant mortality rate following surgery.Insufficient dietary consump-tion and an elevated metabolic rate within tumor cells contribute to the increased proba-bility of malnutrition associated with the ailment,consequently leading to a sub-stantial deterioration in prognosis.Recent studies,reinforce the importance of nu-tritional and immune-inflammatory biomarkers.Prior to surgical intervention,geriatric nutritional risk and systemic immune-inflammatory indices should be prioritized,particularly in older patients with malignant diseases.

Correlation between shock index and inflammation, oxidative stress as well as target organ damage in patients with sepsis

Objective:To study the correlation between shock index and inflammation, oxidative stress as well as target organ damage in patients with sepsis.Methods: A total of 70 patients with sepsis treated in our hospital between March 2013 and May 2016 were collected and divided into no shock group (SI<0.5) (n=11), general shock group (0.5 SI 2) (n=42) and severe shock group (SI>2.0) (n=17) according to the shock index (SI). Immediately after admission, serum levels of inflammatory factors, oxidative stress indexes and liver function indexes were detected.Results:Serum interleukin-1β (IL-1β), interleukin-8 (IL-8), tumor necrosis factor (TNF-α), advanced oxidation protein products (AOPPs), total bilirubin (TB),γ-glutamyl transpeptidase (GGT) and alanine aminotransferase (ALT) levels of severe shock group and general shock group were higher than those of no shock group while anti-inflammatory factors interleukin-10 (IL-10), interleukin-13 (IL-13), soluble tumor necrosis factor receptorⅠ(sTNF-RI), glutathione peroxidase (GSH-Px) and superoxide dismutase (SOD) and catalase (CAT) levels were lower than those of no shock group;serum IL-1β, IL-8, TNF-α, AOPPs, TB, GGT and ALT levels of severe shock group were higher than those of general shock group while IL-10, IL-13, sTNF-RI, CAT, GSH-Px and SOD levels were lower than those of general shock group.Conclusion:The higher the shock index in patients with sepsis, the more severe the inflammation, oxidative stress and target organ damage, and the two are positively correlated.

Inflammation scores predict survival for hepatitis B virus-related hepatocellular carcinoma patients after transarterial chemoembolization

AIM:To compare the prognostic ability of inflammation scores for patients with hepatitis B virus(HBV)-related hepatocellular carcinoma(HCC)undergoing transarterial chemoembolization(TACE).METHODS:Data of 224 consecutive patients who underwent TACE for unresectable HBV-related HCC from September 2009 to November 2011 were retrieved from a prospective database.The association of inflammation scores with clinicopathologic variables and overall survival(OS)were analyzed,and receiver operating characteristic curves were generated,and the area under the curve(AUC)was calculated to evaluate the discriminatory ability of each inflammation score and staging system,including tumor-node-metastasis,Barcelona Clinic Liver Cancer,and Cancer of the Liver Italian Program(CLIP)scores.RESULTS:The median follow-up period was 390 d,the one-,two-,and three-year OS were 38.4%,18.3%,and 11.1%,respectively,and the median OS was 390d.The Glasgow Prognostic Score(GPS),modifed GPS,neutrophil-lymphocyte ratio,and Prognostic Index were associated with OS.The GPS consistently had a higher AUC value at 6 mo(0.702),12 mo(0.676),and24 mo(0.687)in comparison with other inflammation scores.CLIP consistently had a higher AUC value at6 mo(0.656),12 mo(0.711),and 24 mo(0.721)in comparison with tumor-node-metastasis and Barcelona Clinic Liver Cancer staging systems.Multivariate analysis revealed that alanine aminotransferase,GPS,and CLIP were independent prognostic factors for OS.The combination of GPS and CLIP(AUC=0.777)was superior to CLIP or GPS alone in prognostic ability for OS.CONCLUSION:The prognostic ability of GPS is superior to other inflammation scores for HCC patients undergoing TACE.Combining GPS and CLIP improved the prognostic power for OS.

Inflammation-based factors and prognosis in patients with colorectal cancer

Several parameters for predicting survival in patients with colorectal cancer have been identified, including the performance status, age, gender and tumor-nodemetastasis(TNM) stage. Although the TNM stage is important and useful for predicting the prognosis and determining the appropriate treatment, it is well known that the survival time varies widely, even in patients with the same stage of disease. Therefore, the identification of new parameters capable of more precisely predicting patient survival is needed to help select the optimal treatment, especially in patients in the advanced stage of disease. Although the TNM stage reflects the tumor characteristics, cancer progression and survival are not determined solely based on the local characteristics of the tumor, but also the host systemic immune/inflammatory response. Therefore, using a combination of parameters that reflect both tumor characteristics and the host systemic inflammatory status is thought to be important for accurately predicting patient survival.

目的研究术前血小板分布宽度(Platelet volume distribution width,PDW)联合系统性炎症指数(Systemic inflammation response index,SIRI)对结肠癌术后复发转移的预测价值。方法以2020年1月-2021年6月江苏大学附属医院胃肠外科就诊并接受根治性切除手术治疗的194例结肠癌患者为结肠癌组,选择同期在本院体检中心招募的100例健康体检者为对照组。术前检测并记录PDW和SIRI,收集患者的一般资料包括:性别、年龄、身高、体重、家族肿瘤史、是否吸烟、酗酒、体质指数(Body mass index,BMI)、肿瘤最大径、TNM分期(Tumor node metastasis,TNM)和分化程度。对患者随访2年,记录结肠癌复发转移情况。采用ROC曲线确定相关变量的临界最佳值,通过AUC(ROC曲线下面积)评价其预后的准确性。结果与对照组比较,结肠癌组PDW和SIRI均显著增高,差异有统计学意义(P<0.05)。术后发生复发转移患者术前PDW与SIRI高于术后未发生复发转移的患者,差异有统计学意义(P<0.05)。TNM分期Ⅲ~Ⅳ期和中低分化程度术后复发转移患者的PDW高于Ⅰ~Ⅱ期患者和高分化程度患者,差异有统计学意义(P<0.05)。肿瘤最大径≥5 cm、TNM分期Ⅲ~Ⅳ期和中低分化程度术后复发转移患者的PDW高于肿瘤最大径<5 cm、TNM分期Ⅰ~Ⅱ期和高分化程度的患者,差异有统计学意义(P<0.05)。PDW、SIRI及两者联合预测结肠癌术后复发转移的曲线下面积(Area under curve,AUC)分别为0.761(95%CI:0.691~0.831),0.836(95%CI:0.775~0.897)和0.918(95%CI:0.876~0.960)。术后复发转移患者的PDW与SIRI呈显著正相关关系(r=0.574,P=0.003)。结论PDW、SIRI与结肠癌患者临床病理特征和术后复发转移有关,两者联合预测术后复发转移的效能较好,可为临床应用提供一定参考价值。

C反应蛋白联合全身免疫炎症指数对非老年动脉瘤性蛛网膜下腔出血的预后价值

目的探讨C反应蛋白(CRP)、全身免疫炎症指数(SⅡ)对非老年动脉瘤性蛛网膜下腔出血(aSAH)患者的预后价值。方法收集2021年7月至2023年4月郑州大学第五附属医院住院的108例aSAH患者的临床资料,根据出院3个月的改良Rankin量表(mRS)评分标准将患者分为预后良好组(mRS 0~2分)和预后不良组(mRS 3~6分),比较两组患者的临床资料,分析预后不良的独立影响因素,并绘制受试者工作特征(ROC)曲线评估不同独立影响因素对患者预后不良的预测价值。结果108例非老年aSAH患者中预后不良组48例,预后良好组60例。单因素分析结果显示,两组患者在Fisher分级、Hunt-Hess分级、CRP、白细胞计数、淋巴细胞计数、中性粒细胞计数、SⅡ方面差异均有统计学意义(P<0.05)。多因素logistic回归分析结果显示,Fisher分级、CRP、SⅡ是非老年aSAH患者预后不良的独立影响因素。ROC曲线分析结果显示CRP与SⅡ预测非老年aSAH患者预后不良的敏感度、特异度、曲线下面积(AUC)分别为99.9%、60.0%、0.874和95.8%、63.3%、0.881,二者联合预测非老年aSAH患者预后不良的敏感度、特异度、AUC分别为72.9%、95.0%、0.911。结论升高的CRP与SⅡ是非老年aSAH患者预后不良的重要指标,二者联合的预测价值最高。

经验性膳食炎症指数与老年冠心病患者病情及炎症状态的关系

目的:探讨经验性膳食炎症指数(eDⅡ)与老年冠心病患者病情及炎症状态的关系。方法:选取2021年1月—2023年1月在本院收治的老年冠心病患者45例作为病例组,选取同期30名健康体检者作为对照组。进一步依据Gensini评分评估患者病情,分为轻度组、中度组、重度组。采用酶联免疫吸附法检测IL-6、IL-10、CTP、CatK、MMP-2、MMP-9,采用双抗体夹心酶联免疫吸附试验检测TNF-α,采用免疫散射比浊法检测hs-CRP。比较不同组eDⅡ评分、炎症因子、Gensini评分,相关性分析eDⅡ与病情及炎症状态的关系。结果:病例组eDⅡ、炎症因子均高于对照组(P<0.05);3组eDⅡ、炎症因子、Gensini评分比较差异有统计学意义(P<0.05),重度组最高,中度组次之,轻度组最低;3组斑块稳定性相关指标(CTP、CatK、MMP-2、MMP-9)比较差异有统计学意义(P<0.05),重度组最高,中度组次之,轻度组最低;相关性分析显示,老年冠心病患者eDⅡ与斑块稳定性相关指标、炎症因子均呈正相关(P<0.05)。结论:高eDⅡ值与较高的炎症因子水平和Gensini评分相关,提示了膳食炎症对冠心病的发展和炎症状态的影响,通过调整饮食以降低膳食炎症指数,可能有助于改善老年冠心病患者的病情和炎症状态。
