C-reactive protein to albumin ratio predict responses to programmed cell death-1 inhibitors in hepatocellular carcinoma patients

BACKGROUND Over the years,programmed cell death-1(PD-1)inhibitors have been routinely used for hepatocellular carcinoma(HCC)treatment and yielded improved survival outcomes.Nonetheless,significant heterogeneity surrounds the outcomes of most studies.Therefore,it is critical to search for biomarkers that predict the efficacy of PD-1 inhibitors in patients with HCC.AIM To investigate the role of the C-reactive protein to albumin ratio(CAR)in evaluating the efficacy of PD-1 inhibitors for HCC.METHODS The clinical data of 160 patients with HCC treated with PD-1 inhibitors from January 2018 to November 2022 at the First Affiliated Hospital of Guangxi Medical University were retrospectively analyzed.RESULTS The optimal cut-off value for CAR based on progression-free survival(PFS)was determined to be 1.20 using x-tile software.Cox proportional risk model was used to determine the factors affecting prognosis.Eastern Cooperative Oncology Group performance status[hazard ratio(HR)=1.754,95%confidence interval(95%CI)=1.045-2.944,P=0.033],CAR(HR=2.118,95%CI=1.057-4.243,P=0.034)and tumor number(HR=2.932,95%CI=1.246-6.897,P=0.014)were independent prognostic factors for overall survival.CAR(HR=2.730,95%CI=1.502-4.961,P=0.001),tumor number(HR=1.584,95%CI=1.003-2.500,P=0.048)and neutrophil to lymphocyte ratio(HR=1.120,95%CI=1.022-1.228,P=0.015)were independent prognostic factors for PFS.Two nomograms were constructed based on independent prognostic factors.The C-index index and calibration plots confirmed that the nomogram is a reliable risk prediction tool.The ROC curve and decision curve analysis confirmed that the nomogram has a good predictive effect as well as a net clinical benefit.CONCLUSION Overall,we reveal that the CAR is a potential predictor of short-and long-term prognosis in patients with HCC treated with PD-1 inhibitors.If further verified,CAR-based nomogram may increase the number of markers that predict individualized prognosis.

C-reactive Protein/Albumin Ratio as a Prognostic Indicator in Posttraumatic Shock and Outcome of Multiple Trauma Patients

Objective C-reactive protein(CRP)/albumin ratio(CAR)is a new inflammation-based index for predicting the prognosis of various diseases.The CAR determined on admission may help to predict the prognostic value of multiple trauma patients.Methods A total of 264 adult patients with severe multiple trauma were included for the present retrospective study,together with the collection of relevant clinical and laboratory data.CAR,CRP,albumin,shock index and ISS were incorporated into the prognostic model,and the receiver operating characteristic(ROC)curve was drawn.Then,the shock index for patients with different levels of CAR was analyzed.Finally,univariate and multivariate logistic regression analyses were performed to identify the independent risk factors for the 28-day mortality of multiple trauma patients.Results A total of 36 patients had poor survival outcomes,and the mortality rate reached 13.6%.Furthermore,after analyzing the shock index for patients with different levels of CAR,it was revealed that the shock index was significantly higher when CAR was≥4,when compared to CAR<2 and 2≤CAR<4,in multiple trauma patients.The multivariate logistic analysis helped to identify the independent association between the variables CAR(P=0.029)and shock index(P=0.019),and the 28-day mortality of multiple trauma patients.Conclusion CAR is higher in patients with severe multiple trauma.Furthermore,CAR serves as a risk factor for independently predicting the 28-day mortality of multiple trauma patients.The shock index was significantly higher when CAR was≥4 in multiple trauma patients.

The prognostic potential of pretreatment C-reactive protein to albumin ratio in stage IE/IIE extranodal natural killer/T-cell lymphoma

Objective The aim of this study was to determine the prognostic significance of the C-reactive protein-toalbumin ratio (CRP/Alb) for stage IE/IIE upper aerodigestive tract extranodal NK/T cell lymphoma patients. Methods One hundred and fourteen patients diagnosed with extranodal NK/T cell lymphoma at Sichuan Cancer Hospital from September 2011 to November 2016 were retrospectively reviewed. An optimal cutoff value of CRP/Alb for overall survival rate as an endpoint was obtained using the receiver operating curve (ROC). Results The optimal cutoff value of CRP/Alb was 0.15. For the low CRP/Alb group, the 3-year progression-free survival (PFS) was 78.6% and the 3-year overall survival (OS) was 80.7%. The 3-year PFS and OS values for the high CRP/Alb group were 41.6% and 45.2%, respectively. Differences for PFS (P < 0.001) and OS (P < 0.001) between the two groups were statistically significant. Univariate analysis showed that ECOG, IPI, CRP, GPS, and CRP/Alb were significantly associated with PFS. Similarly, all five were also significantly associated with OS. Multivariate analysis further confirmed that ECOG and CRP/ Alb were independent prognostic factors for both PFS and OS. Moreover, the cutoff value of CRP/Alb showed superior prognostic ability in discriminating between patients with different outcomes in low-risk group based on GPS, IPI, and KPI scores. Conclusion CRP/Alb is a promising prognostic marker for early-stage extranodal NK/T cell lymphoma.

C-reactive Protein Level,Apolipoprotein B-to-apolipoprotein A-1 Ratio,and Risks of Ischemic Stroke and Coronary Heart Disease among Inner Mongolians in China

Objective We aimed to investigate the cumulative effect of high CRP level and apolipoprotein B-to-apolipoprotein A-1（ApoB/ApoA-1） ratio on the incidence of ischemic stroke（IS） or coronary heart disease（CHD） in a Mongolian population in China.Methods From June 2003 to July 2012,2589 Mongolian participants were followed up for IS and CHD events based on baseline investigation.All the participants were divided into four subgroups according to C-reactive protein（CRP） level and ApoB/ApoA-1 ratio.Cox proportional hazard models were used to estimate the hazard ratios（HRs） and 95% confidence intervals（CIs） for the IS and CHD events in all the subgroups.Results The HRs（95% CI） for IS and CHD were 1.33（0.84-2.12）,1.14（0.69-1.88）,and 1.91（1.17-3.11） in the ‘low CRP level with high ApoB/ApoA-1＇,‘high CRP level with low ApoB/ApoA-1＇,and ‘high CRP level with high ApoB/ApoA-1＇ subgroups,respectively,in comparison with the ‘low CRP level with low ApoB/ApoA-1＇ subgroup.The risks of IS and CHD events was highest in the ‘high CRP level with high ApoB/ApoA-1＇ subgroup,with statistical significance.Conclusion High CRP level with high ApoB/ApoA-1 ratio was associated with the highest risks of IS and CHD in the Mongolian population.This study suggests that the combination of high CRP and ApoB/ApoA-1 ratio may improve the assessment of future risk of developing IS and CHD in the general population.

Preoperative lymphocyte to C-reactive protein ratio as a new prognostic indicator in patients with resectable gallbladder cancer

Background:Inflammation is often related to cancer,and several inflammatory scores have been established to predict the prognosis of various types of cancer.Our study aimed to determine the prognostic value of the preoperative lymphocyte to C-reactive protein ratio(LCR)for predicting postoperative outcomes in patients with resectable gallbladder cancer(GBC).Methods:A retrospective analysis of 104 GBC patients who received curative surgery at Xinhua Hospital,Affiliated to Shanghai Jiao Tong University School of Medicine from January 2000 to December 2016 was performed.A time-dependent receiver operating characteristic curve was constructed to evaluate the accuracy of different markers.Univariate and multivariate Cox proportional hazard models were used to define factors associated with overall survival.Results:Among the assessed variables,the preoperative LCR showed the highest accuracy in predicting the overall survival of GBC patients(AUC:0.736).Decreased preoperative LCR was significantly associated with advanced tumor stage,including tumor invasion(P=0.018),lymph node metastasis(P=0.011)and TNM stage(P=0.022).A low preoperative LCR(cutoff threshold=145.5)was an independent risk factor for overall survival in patients with resectable GBC(P<0.001).Conclusions:The preoperative LCR is a novel and valuable prognostic indicator of postoperative survival in patients with resectable GBC.

Diagnostic and prognostic significance of the lymphocyte/C-reactive protein ratio,neutrophil/lymphocyte ratio,and D-dimer values in patients with COVID-19

In this study,our aim was to examine the diagnostic and prognostic significance of lymphocyte/C-reactiveprotein ratio(LCR),neutrophil/lymphocyte ratio(NLR)and D-dimer parameters in COVID-19 infection.The LCR,NLR,neutrophil count,mean platelet volume(MPV),C-reactive protein(CRP),and D-dimer parameters wereevaluated retrospectively.This was a retrospective cohort study with 1000 COVID-19 positive and 1000 healthycontrol groups,all over the age of 18 years.Odds ratio(OR)and 95%confidence interval(CI)values were calculatedfor each parameter found to be statistically significant in the univariate and multivariate logistic regression models.Herein,127(12.7%)of the COVID-19^(+)patients,whose data was included in this study,died.The neutrophil,MPV,CRP,D-dimer,and NLR values were higher in the COVID-19^(+)/deceased group than in the COVID-19^(+)/alive andcontrol groups(p<0.001,p<0.001,p<0.001,p<0.001,p<0.001).The lymphocyte and LCR values were lower inthe COVID-19^(+)/deceased group than in the COVID-19^(+)/alive and control groups(p<0.001,p<0.001).Variableswith statistically significance in predicting COVID-19 infection were lymphocyte,LCR,D-dimer,NLR,CRP,MPV,PLT,and neutrophil values.Statistically significant variables in predicting mortality due to COVID-19 were LCR,CRP,NLR,lymphocyte,D-dimer,neutrophil,and MPV values.A low LCR and high NLR are associated with thepresence,prognosis,and mortality due to COVID-19.LCR and NLR parameters can thus be used in clinicalmonitoring to reduce morbidity and mortality rates.

C-reactive protein/albumin ratio as a predictor for severe coronary artery disease in patients with stable angina pectoris

Background Syntax score(SS),an angiographic tool to grade the complexity of coronary artery disease,has prognostic importance for this disease. C-reactive protein(CRP)and albumin are indicators of inflammation.And both of them are associated with high SS. Hence,we aimed to investigate whether baseline CRP to albumin ratio(CAR)is associated with SS. Method A total of 312 consecutive patients with stable angina pectoris,who underwent coronary angiography for suspected coronary artery disease(CAD)from January 2018 to May 2019,were classified into two groups,low score group(syntax score≤22)and high score group(syntax group>22).The Multivariate logistic analysis and ROC curve were performed to detect the predictive effect of CAR for higher SS. Results There are 163 cases in the low score group while 149 cases in the high score group. CAR in the high score group was significantly higher than the other group(5.6[2.8-9.6]vs. 2.5[1.7-5.2],P<0.01). In multivariate logistic regression analysis,CAR was proved to be an independent predictor for high syntax score. ROC curve analyses reveal the good predictive values of CAR(AUC 0.731,95% CI:0.608-0.814,P<0.01)for high syntax score and statistical significant better than CRP or albumin alone. Conclusions CAR is independently associated with the complexity and severity of CAD,which has better predictive value than CRP or albumin alone.

NLR与CAR及联合指标对脓毒症患者28天死亡率的预测价值

目的探讨中性粒细胞与淋巴细胞比值(NLR)、C反应蛋白与白蛋白比值(CAR)对脓毒症患者28 d死亡率的预测价值。方法采用回顾性分析方法,将2021年1月-2022年12月期间入住本院ICU的224例脓毒症患者作为研究对象。收集患者入院24 h内的一般资料、临床检查指标,根据患者28 d生存情况,将患者分为生存组和死亡组,对比两组间各指标的差异,并评价各指标对患者预后的判断价值。结果存活组153例,死亡组71例。两组患者中性粒细胞计数、白蛋白、乳酸、APACHE-Ⅱ评分、CRP、NLR、CAR的差异均有统计学意义(P<0.05或P<0.001)。NLR、CAR、APACHE-Ⅱ评分是导致脓毒症患28 d病死率增加的独立危险因素。NLR联合CAR用于评估脓毒症患者预后的AUC大于NLR、CAR单独应用,与APACHE-Ⅱ评分相当,而NLR、CAR与APACHE-Ⅱ评分三者联合的AUC大于两者联合。结论NLR、CAR均对脓毒症患者的预后评估有一定的预测作用,而NLR联合CAR可以提高其预测价值。
