C-Reactive Protein-Albumin Ratio (CAR): A More Promising Inflammation-Based Prognostic Marker for Patients Undergoing Curative Hepatectomy for Hepatocellular Carcinoma.

Systemic inflammatory response is a hallmark of cancer and plays a significant role in the development and progression of various malignant tumors. This research aimed to estimate the prognostic function of the C-reactive protein-albumin ratio (CAR) in patients undergoing hepatectomy for hepatocellular carcinoma (HCC) and compare it with other inflammation-based prognostic scores, including the neutrophil-lymphocyte ratio, platelet-lymphocyte ratio, monocyte-lymphocyte ratio, systemic immune inflammation index, prognostic index, Glasgow prognostic score, and modified Glasgow prognostic score. Retrospective analysis was conducted on data from 1039 HCC cases who underwent curative liver resection. The prognostic performance of CAR was compared with other scores using the area under the time-dependent receiver operating characteristic (t-ROC) curve. Multivariable Cox regression analyses were performed to confirm independent predictors for disease-free survival (DFS) and overall survival (OS). The area under the t-ROC curve for CAR in the evaluation of DFS and OS was significantly greater than that of other scores and alpha-fetoprotein (AFP). Patients were stratified based on the optimal cut-off value of CAR, and the data revealed that both DFS and OS were remarkably worse in the high-CAR set compared to the low-CAR set. Multivariable Cox analysis demonstrated that CAR was an independent prognostic parameters for assessing DFS and OS. Regardless of AFP levels, all patients were subsequently divided into significantly different subgroups of DFS and OS based on CAR risk stratification. Similar results were observed when applying CAR risk stratification to other scoring systems. CAR also showed good clinical applicability in patients with different clinical features. CAR is a more effective inflammation-based prognostic marker than other scores and AFP in predicting DFS as well as OS among patients with HCC after curative hepatectomy.

Value of C-reactive protein/albumin ratio in predicting the development of preoperative oxygenation impairment in patients with Stanford type-B acute aortic dissection

ObjectivesWe aimed to assess the predicting value of C-reactive protein (CRP)/albumin ratio (CAR) in the development of Oxygenation impairment (OI) in the patients with Stanford type-B acute aortic dissection (AAD). MethodsThis study included 133 patients (age = 58.8 ± 12.0 years, median age = 61 years, Male/Female = 117/16) diagnosed as Stanford type-B AAD accompanied by hypertension from July 2012 to May 2020.Clinical data were retrospectively extracted from the database. The patients in this study were divided into OI group (oxygenation index ≤ 200) and non-OI group (oxygenation index > 200). Clinical characteristics in both groups were compared, and predicting value of CAR in the development of OI was assessed. ResultsPatients in OI group had higher peak body temperature (37.94 ± 0.62 vs. 37.67 ± 0.51 ℃, P =.010), higher levels of serum CRP (41.74 ± 27.71 vs 15.21 ± 19.66 mg/L, P =.000) and plasma B-type natriuretic peptide (292.14 ± 251.11 vs 179.80 ± 241.27 ng/L, P =.016), lower levels of albumin (34.00 ± 5.14 vs 37.72 ± 5.24 g/L, P =.000), and higher CAR (1.27 ± 0.89 vs 0.41 ± 0.53, P =.000). In multivariate regression analysis, CAR (odds ratio: 5.215, 95 % CI: 2.682; 10.137, P =.000) and the peak body temperature (odds ratio: 2.905, 95 % CI: 1.255; 6.724, P =.013) could significantly predict the OI development. The AUC for CAR was 0.831 (95 % CI: 0.756–0.907). An optimal cutoff value for CAR for predicting OI was ≥ 0.70, with a sensitivity of 67.5 % and a specificity of 88.2 %. ConclusionsCompared with CRP or albumin alone, the CAR might be a more accurate marker in predicting OI development in Stanford type-B AAD.

The C-reactive protein Albumin ratio was not consistently associated with cardiovascular and all-cause mortality in two community-based cohorts of 70-year-olds

C-reactive protein (CRP)/Albumin ratio (CAR) seems to mirror disease severity and prognosis in several acute disorders particularly in elderly patients, which we aimed to study. As method we use a prospective study design; the Prospective Investigation of the Vasculature in Uppsala Seniors (PIVUS; n = 912, women 50%; mean age 70 years, baseline 2001 and 2004, median follow-up 15.0 years, end of follow-up 2019) and the Uppsala Longitudinal Study of Adult Men (ULSAM, n = 924 mean age 71 years, baseline 1991–1995, median follow-up 15.6 years, end of follow-up 2016). Serum samples were used for analyses of CRP and Albumin. Cox regression analyses were performed for cardiovascular and all-cause mortality in models adjusting for several factors (age; physical activity; Interleukin-6; cardiovascular (CVD) risk factors: smoking, BMI level, systolic blood pressure, LDL-cholesterol, and diabetes), with 95% confidence interval (CI). When adjusting for age and CVD risk factors, CAR was significantly associated with cardiovascular mortality for meta-analyzed results from PIVUS and ULSAM, HR 1.09 (95% 1.01–1.18), but neither in PIVUS (HR 1.14, 95% CI 0.99–1.31) nor in ULSAM (1.07, 95% CI 0.98–1.17). Additionally, CAR was significantly associated with all-cause mortality in ULSAM 1.31 (95% CI 1.12–1.54) but not in PIVUS HRs 1.01 (95% 0.089-1.15). The predictive value of CAR was similar to CRP alone in PIVUS and ULSAM and slightly better than albumin for the prediction of CVD-mortality in ULSAM. In conclusion, CAR was not consistently associated with cardiovascular and all-cause mortality in the two cohorts. The prognostic value of CAR for long-term CVD-mortality was similar to CRP.

CRP/albumin ratio in predicting 1-year mortality in elderly patients undergoing hip fracture surgery.

In the literature, rates of up to 37.1% have been reported for 1-year mortality after hip fractures. In this study, we aimed to determine whether the C-reactive protein/albumin ratio (CAR) is an independent risk factor for 1-year mortality after hip fracture and whether CAR, neutrophil/lymphocyte ratio (NLR), CRP, albumin level, and other parameters have an effect on mortality and morbidity. Over a 3-year period, 480 patients aged 65 years and older who underwent hemiarthroplasty for hip fracture were analyzed. A univariate logistic regression analysis was performed to identify prognostic factors for 1-year mortality. Significant variables were re-evaluated using binary logistic regression analysis. The number of patients who died within 1 year postoperatively was 95 (27.7%), and the median age was 85 years. In the receiver operating characteristic analysis (ROC) for 1-year mortality after hip fracture, the optimal cut-off value of CAR was found to be 1.03. The area under the curve (AUC) for mortality was 0.843, the sensitivity was 65.3%, and the specificity was 92.7% [95% confidence interval (CI), 0.791-0.895; p < 0.001]. The optimal cut-off value for CRP was 2.85, the AUC was 0.838, the sensitivity was 70%, and the specificity was 89% (95% CI, 0.785-0.890; p < 0.001). The optimal cut-off value of NLR for postoperative intensive care unit (ICU) admission was determined to be 6.64. CAR was a predictive factor for 1-year postoperative mortality and postoperative ICU admission, whereas NLR was a predictive factor for postoperative ICU admission.

An Exciting Performance of Established and Novel Biomarkers in Diagnosing Periprosthetic Joint Infections: A Single-center Retrospective Cohort Study.

Significant progress has been made in recent years in the diagnosis of periprosthetic joint infections (PJI). However, the lack of a gold standard test for the diagnosis of PJI remains a challenge.The aim of this study was to evaluate the diagnostic values of the albumin/fibrinogen ratio (AFR), the C-reactive protein/albumin ratio (CAR), and the levels of fibrinogen (FIB) and albumin (ALB) in the diagnosis of PJI. The medical records of 158 patients who had undergone hip or knee revisions from January 2018 to May 2022 were retrospectively analyzed. Of these patients, 79 were diagnosed with PJI, while 79 were diagnosed with aseptic loosening (AL). PJI was defined using the Musculoskeletal Infection Society criteria. The plasma levels of C-reactive protein (CRP), ALB, and FIB; the erythrocyte sedimentation rate (ESR); and the AFR and CAR in the two groups were recorded and analyzed. The receiver operating characteristic curve was used to calculate the sensitivity and specificity of each indicator; the diagnostic value for each indicator was calculated as the area under the curve (AUC). The ESR, CRP, FIB, and CAR values in the PJI group were significantly higher than those in the AL group, and the ALB and AFR values were significantly lower than those in the AL group (p < 0.001). The AUC values of AFR and fibrinogen were 0.851 and 0.848, respectively, which were slightly higher than those of CRP (0.826) and ESR (0.846). The AUC of CAR was 0.831 which was slightly lower than that of CRP (0.846). ALB had an AUC of 0.727. The optimal threshold, sensitivity, and specificity, respectively, were 10.05, 84.81%, and 82.28% for AFR; 4.03 μg/mL, 77.22%, and 86.08% for FIB; 0.23, 72.15%, and 82.28% for CAR; and 37.30 g/L, 65.82%, and 73.42% for ALB. AFR, CAR, and FIB are good new auxiliary diagnostic indicators of PJI, while ALB is of fair value for the diagnosis of PJI.

The relationship between albumin and its proportion to other markers in predicting mortality in severe COVID-19 patients.

The aim of the present study was to investigate the relationship between albumin, blood urea nitrogen (BUN)/albumin ratio (BAR), D-dimer/albumin ratio (DAR), C-reactive protein (CRP)/albumin ratio (CAR), and neutrophil/albumin ratio (NAR) levels and prognosis in severe COVID-19 cases. A total of 619 patients diagnosed with severe COVID-19 in the emergency department were retrospectively analyzed. BAR, DAR, CAR, and NAR values were obtained by dividing BUN, neutrophil, CRP, and D-dimer by albumin. All patients were divided into groups [survived and deceased patients, and those who received and did not receive mechanical ventilation (MV) assistance]. These groups were statistically compared with regard to albumin, BAR, DAR, CAR, and NAR. While 350 out of 619 patients survived, 269 patients died. A statistically significant difference was determined between survived and deceased patient groups with regard to BUN, neutrophil, lymphocyte, CRP, D-dimer, albumin, BAR, NAR, DAR, and CAR levels (p<0.001 for all). Also, BAR, NAR, DAR, and CAR were significantly higher in those who received MV support, while albumin was found to be low (p<0.001). According to receiver operating characteristic (ROC) analysis, NAR, BAR, CAR, albumin, and DAR had the highest area under the curve (AUC) values compared to the other parameters (0.825, 0.815, 0.806, 0.772, and 0.770, respectively) (p<0.001 for all). According to logistic regression analysis, BAR, NAR, DAR, and CAR levels were determined as important risk factors for mortality. Low serum albumin levels can be used for severity as an additional tool in severe COVID-19 patients. Moreover, the NAR, BAR, and CAR levels were found to be more valuable than albumin levels in predicting prognosis in these patients.

Could the C-reactive protein/albumin Ratio Predict Mortality in Patients with Common Variable İmmunodeficiency?

Common variable immunodeficiency (CVID) is the most common symptomatic immunodeficiency in adults. This study assessed the utility of using the C-reactive protein (CRP)/albumin ratio (CAR) at diagnosis to predict mortality in CVID patients. Between 2010 and 2022, hospital records and follow-up cards of patients with CVID were reviewed retrospectively. Seventy-five patients were included in the study. CRP 0–5 mg/L and albumin 3.5–5.5 g/dL were taken as references. The CAR was obtained by dividing the CRP value by the albumin value. Of the included patients, 41 (55%) were male and 34 (35%) were female. The median age was 38 (21–77) years. The mortality rate of the patients during the follow-up time was 20%. Of the patients, 41% had splenomegaly, 10.6% had malignancy, and 39% had bronchiectasis. The cut-off value of CAR to predict mortality was &amp;gt;2.18 (sensitivity: 88.4%, specificity: 90.1%). When the patients were classified according to the CAR, the mortality rate in the patient group with a CAR &amp;gt; 2.18 was statistically significantly higher than the patient group with a CAR ≤ 2.18. The CAR is a cheap, simple, and easily calculated parameter that can predict mortality in CVID patients.

Relationship Between High Sensitivity C-reactive Protein to Albumin Ratio With Infarct-related Artery Patency in Patients With Non-ST-segment Elevation Myocardial Infarction.

The C-reactive protein/albumin ratio (CAR) has recently emerged as a marker for poor prognosis or mortality in various patient groups. This study aimed to examine the relationship between serum CAR and infarct-related artery (IRA) patency in 700 consecutive non-ST-segment elevation myocardial infarction (NSTEMI) patients prior to percutaneous coronary intervention. The study population was separated into 2 different groups according to preprocedural IRA patency as assessed by the degree of Thrombolysis in Myocardial Infarction (TIMI) flow. As a result, occluded IRA was defined as TIMI grade 0-1, while patent IRA was defined as TIMI grade 2-3. High CAR (Odds Ratio: 3.153 (1.249-8.022); P < .001) was found to be an independent predictor of occluded IRA. Additionally, CAR was positively correlated with the SYNTAX score, neutrophil/lymphocyte ratio, and platelet/lymphocyte ratio; CAR was negatively correlated with left ventricular ejection fraction. The highest cut-off value of CAR predicting occluded IRA was found to be .18 with 68.3% sensitivity and 67.9% specificity. The area under the curve for CAR was .744 (95% CI: .706-.781) after the receiver-operating characteristic curve assessment.

P177 C-reactive protein/albumin ratio: a novel biomarker for monitoring of the disease activity in Ulcerative Colitis patients

Abstract Background Fecal calprotectin (FC) is a reliable laboratory test for non-invasive assessment of disease activity in ulcerative colitis (UC) patients; it's high cost, absence of widespread availability and low patient adherence limits it's use as a potential surrogate for endoscopy. The association of higher C-reactive protein (CRP) and low albumin levels, both obtained from patient's sera, with disease acitivity in UC, is well established. C-reactive protein/albumin ratio (CAR) is suggested as a biomarker for evaluating disease activity in various inflammatory conditions. We aimed to evaluate association between CAR, FC, CRP and serum albumin values with disease activity in UC patients. Methods A single center, noninterventional retrospective chart review of adult UC patients treated with biologics at a tertiary center was performed. Routine clinical (stool frequency score – SFS, and rectal bleeding score – RBS), biochemical (CRP, serum albumin, FC), and endoscopic (Mayo Endoscopic Subscore – MES) findings were assessed prior to initiating biologics. Active UC was defined as SFS 2/3 + RBS 2/3 + MES 2/3. Differences between continuous variables were calculated using independent sample t-tests and Mann–Whitney U test. Sperman’s correlation and ROC curve analysis were carried out. The Z statistic was used to compare correlation coefficients and AUC. Results Total of 82 patients (52.2% females, mean age 40.3 ± 15.3 years, smokers 16.9%) with dominantly extensive UC (57.3%) were analysed. The CAR (0.175 vs 0.025; p=0.02) and FC (1363.5 vs 65.5; p=0.01) levels were significantly higher in active vs inactive UC patients. Positive correlation was observed between CAR (rs = 0.354, p = 0.01), FC (rs = 0.448, p = 0.001) and CRP (rs = 0.316, p = 0.005) with active UC. Although serum albumin (r's = - 0.093, p = 0.532) negatively correlated with disease activity it didn't reach statistical significance. There was no statistically significant difference between CAR and FC correlation coefficients. The area under the curve (AUC) for the diagnosis of active UC was 0.896 (SE: 0.058; 95% CI 0.73 - 0,983, p=0.015) and 0.994 (SE: 0.009; 95% CI 0.98 - 1, p=0.001) for CAR and FC, respectively. Although AUC for FC was higher compared to CAR it didn’t reach statistical significance (p = 0.1). The cut-off value associated with the active UC for CAR was 0.06 (sensitivity 77,2%, specificity 100%), and 120 mcg/g for FC (sensitivity 97.6%, specificity 100%). Conclusion There is good correlation between CAR and clinical as well as endoscopic disease activity in patients with UC, comparable to FC. CAR could be offered as a cheap and practical biomarker for detection of active UC disease.

Investigation of inflammation marker ratios that can be used as predictors of in-hospital mortality in traumatic acute subdural hematoma

Purpose: The aim of the present study is to determine inflammatory mediators that may be used in predicting in-hospital mortality in a traumatic acute subdural hematoma (TASDH) patients and to evaluate their significance as prognostic markers. Methods: The medical records of adult patients with traumatic acute subdural hematoma admitted to the emergency department were reviewed retrospectively. The primary clinical outcome was in-hospital mortality. Univariate and multivariate Cox regression analyses were performed for the identification of independent predictors of in-hospital mortality. Besides, receiver operating characteristic (ROC) analysis was applied to determine the power of inflammatory mediators in predicting mortality. Results: According to the Cox hazard models, the mean platelet volume (MPV) /platelet count (PLT) ratio (MPR) (Hazard Ratio (HR) = 1.129; 95% CI = 1.059 – 1.204; p &lt; 0.001), C-reactive protein (CRP)/lymphocyte ratio (CLR) (HR = 1.011; 95% CI = 1.002 – 1.020; p = 0.022) and C-reactive protein(CRP)/albumin ratio (CAR) (HR =1.004; 95% CI = 1.001 – 1.007; p = 0.004 were risk factors for in-hospital mortality. The results of ROC analysis indicated that the MPR of 0.06 or above predicted in-hospital mortality with 67% sensitivity and 88% specificity (p = 0.001). In addition, the CLR of 39.12 and above predicted in-hospital mortality with 63% sensitivity and 93% specificity and the CAR of 8.79 (p = 0.001) and above predicted it with 66% sensitivity and 87% specificity (p = 0.002) Conclusion: Increased MPR, CLR and CAR values are strong predictors of in-hospital mortality in TASDH patients.

A Practical and Applicable New Index as an Indicator of Inflammation in the Diagnosis of Erectile Dysfunction: C-reactive Protein-to-Albumin Ratio

Current evidence suggests that the significant underlying pathophysiological mechanism in erectile dysfunction (ED) is endothelial dysfunction. It is clinically essential to monitor ED because inflammatory processes lead to dysfunctional endothelium and the progression of atherosclerosis. The current retrospective analysis assessed the registers of 90 patients with ED complaints (ED group) and 78 healthy people without ED complaints (control group) who were being managed at the urology units of the surgical outpatient clinic. The international index of erectile function-5 (IIEF-5) evaluated the ED. C-reactive protein (CRP)/albumin ratio (CAR) value was determined by manually dividing serum CRP value by the albumin value in patients whose CRP value was between 0 and 5 mg/l. The average CAR was 0.45 ± 0.37 (ED group) versus 0.22 ± 0.1 in the control group (p=0.0001). IIEF-5 results were negatively correlated with CAR values (r=−0.299; p=0.0001). The strongest cut-off of CAR for predicting ED was 0.025, with 81.8% sensitivity and 75% specificity (p=0.0001). The ED group showed higher levels of CAR and CRP than the control group. CAR can be used as a practical, easy-to-calculate, and cost-effective index in diagnosing ED patients.

The Predictive Value of C-Reactive ProteinAlbumin Ratio in Long-Term Mortality Among Patients Undergoing Carotid Artery Stenting

Introduction: Several inflammatory biomarkers reported in previous research have been associated with the severity of carotid artery stenosis, symptomatic carotid lesions, and carotid stent restenosis. The C-reactive protein (CRP)-to-serum albumin ratio (CAR) has been shown to predict peripheral artery disease severity in patients with carotid artery disease (CAD). However, the relationship between CAR and long-term mortality in CAD patients following carotid artery stenting (CAS) remains uncertain. The goal of this study was to investigate the ability of CAR to predict long-term mortality in patients with CAS. Patients and Methods: A total of 998 CAD patients who had percutaneous carotid artery intervention were reviewed retrospectively, and 482 of them without follow-up data were excluded from this study. The study included patients who had percutaneous carotid artery intervention between 2012 and 2018. Before the procedure, serum CRP, complete blood counts, and albumin levels were measured. The relationships between patients’ characteristics, procedural details, and CAR with all-cause mortality were evaluated in the long-term follow-up after CAS. Results: Older age (HR= 1.044; 95% CI= 1.001-1.089; p= 0.046), smoking (HR= 2.636; 95% CI= 1.213- 5.728; p= 0.014), blood urea (HR= 1.017; 95% CI= 1.002-1.033; p= 0.025), albumin (HR= 0.252; 95% CI= 0.132-0.480; p&lt; 0.001), CRP levels (HR= 1.336; 95% CI= 1.055-1.691; p= 0.016) and CAR (HR= 1.012; 95% CI= 1.003-1.022; p= 0.008) were statistically associated with all-cause mortality at 55.2 ± 12.4 months follow-up after CAS in multivariate COX regression analysis. Conclusion: In patients undergoing CAS, CAR was independently related to long-term mortality. CAR could be used in this population for risk stratification to achieve closer follow-up and optimize treatment.

C-Reactive Protein to Albumin Ratio as a Predictor of Contrast-Induced Nephropathy After Carotid Angiography.

This study evaluated the role of the C-reactive protein (CRP)/albumin ratio (CAR) in estimating the probability of occurring contrast-induced nephropathy (CIN) after carotid artery angiography (CAAG). Patients (n = 410) who had CAAG for carotid artery stenosis (CAS) were included in this study. A spike in serum creatinine was used to define CIN within 72h of the procedure (>.5mg/dL or >25% above baseline). CAR was calculated by dividing the CRP by the albumin level. Patients with CIN had higher numbers of white blood cells (P = .002), numbers of neutrophils (P = .007), neutrophil-lymphocyte ratios (P = .026), high-sensitivity CRP levels (P < .001), and CAR levels (P < .001) than those without CIN. They were also older (P < .001) and more likely to have diabetes mellitus (P = .006) and hypertension (P = .016). According to receiver operator characteristic curve (ROC) analysis, the CAR value has a 75% sensitivity and a 68% specificity for identifying CIN at a cutoff of 1.8. Also, NLR and CRP predicted CIN with 71% sensitivity and 67% specificity, 71% sensitivity and 66% specificity at the best cutoff values of 1.96 and 7.91, respectively. According the present study, in patients with CAS, the development of CIN after CAAG is independently correlated with CAR at admission.

C-reactive protein to albumin ratio in Behçet’s disease

Objectives: This study aims to evaluate the relationship between C-reactive protein (CRP)/albumin ratio (CAR) and other hematological parameters in Behçet's disease (BD). Methods: A total of 200 participants (100 BD patients and 100 healthy control) were recruited from the rheumatology outpatient clinic in this cross-sectional study. Laboratory tests were conducted to measure complete blood count, erythrocyte sedimentation rate (ESR), CRP, albumin, CAR, neutrophil to lymphocyte ratio (NLR), and platelet to lymphocyte ratio (PLR). Laboratory findings of BD patients and healthy controls were compared and evaluated. BD Activity scores (Behçet's Disease Current Activity Form [BDCAF]) were calculated. Results: In the BD group, there were 42 male and 58 female participants with a mean age of 42.49 ± 13.15 years and in the healthy control group, 44 male and 56 female participants with a mean age of 44.90 ± 10.98 years. NLR, CRP, ESR and CAR values were significantly higher in patient group than in the healthy controls (p &amp;lt; 0.05). BDCAF score varied between 0 and 4 with a mean of 1.55 ± 0.64. A statistically significant correlation was observed between BDCAF and CRP, ESR and CAR (p &amp;lt; 0.0001). Conclusions: In this study, a significant correlation was found between CAR and BDCAF, NLR, CRP, albumin and ESR. CAR can be useful in the diagnosis and following of BD patients.

Is CRP/Albumin Ratio (CAR) a New Parameter to be Added to Risk Stratification Systems in Metastatic Renal Cell Carcinoma Patients?

To evaluate the effect of pretreatment C-reactive protein (CRP)/Albumin ratio (CAR) on prognosis and its association with IMDC (International metastatic renal cell carcinoma database consortium) risk score and overall survival (OS) in metastatic renal cell carcinoma (mRCC) patients. Descriptive study. Department of Medical Oncology, Dokuz Eylul University, Izmir, Turkey, between 2007 and 2020. Clinico-pathological and treatment-related data of mRCC patients were retrospectively evaluated and included in the study. CAR was used as a prognostic inflammatory score. CAR threshold value for OS has been obtained by ROC analysis. The prognostic value of CAR was tested using Kaplan-Meier and Cox-regression models. IMDC-CAR model was created by adding CAR to IMDC risk stratification. OS was 91 months in patients with CAR below the threshold value of 0.072 (<0.072), while OS was 51 months in patients with CAR of 0.072 and above (p=0.005). According to IMDC risk stratification, intermediate and poor risk groups showed similar survival times (p>0.05). However, when CAR was added to the IMDC risk score in the intermediate group, it was divided into 3 subgroups with different prognoses (p=0.02). CAR is an independent predictor of OS in mRCC patients. In this study, it has been demonstrated that more accurate prognosis prediction could be made by adding CAR to IMDC indicators in the intermediate risk group, which constitutes a highly heterogeneous group according to IMDC risk stratification.

Inflammation-based prognostic scores in geriatric patients with rectal cancer.

Morbidity/mortality and oncologic outcomes can be worsened in geriatric rectal cancer patients due to comorbidities and frailty. The aim of this study was to compare surgical and oncological results of geriatric rectal cancer patients using inflammation-based prognostic scores. The prospectively maintained database of 991 rectal cancer patients treated at our center between 2007 and 2020 were analyzed. All conventional clinicopathologic features, and oncologic outcomes are compared between patients ≥ 65years old (geriatric patients: Group I) and < 65years old (non-geriatric patients: Group II). The modified Glasgow Prognostic Score (mGPS) and the C-reactive protein-albumin ratio (CAR), were determined. The prognostic value of mGPS and CAR as well as the well-known clinico-pathologic factors to predict surgical morbidity, mortality, local and/or distant recurrence, and overall survival was assessed. There were 567 (57.2%) patients who were ≥ 65years old (Group I; 349 males, median age 74 [range 65-9]) years) and 424 (42.8%) who were < 65years old (Group II; 252 males, median age 58 [range 20-64] years). The high-grade [Clavien-Dindo III-IV] complications rates of Group I and Group II patients sere 20% (n = 113), and 9% (n = 37), respectively. High-grade complications were related to mGPS (p < 0.001) and CAR (p < 0.001) values. The high-grade complication rate was found to be higher in Group I than in Group II, and this was statistically significant (p < 0.001). High preoperative mGPS and CAR values were significantly associated with postoperative mortality (p < 0.001). In Cox multivariate analysis, mGPS (p = 0.003) and CAR (p = 0.001) were significantly in correlation with lowered overall survival. The mGPS and CAR were found to be independent prognostic factors for overall survival. The mGPS and CAR can predict severe postoperative complications and early mortality. mGPS, and CAR have a powerful prognostic value and the potential clinical usefulness to predict decreased overall survival in both geriatric and non-geriatric rectal cancer patients.

C-reactive protein-albumin ratio and procalcitonin in predicting intensive care unit mortality in traumatic brain injury.

BackgroundPrediction of intensive care unit (ICU) mortality in traumatic brain injury (TBI), which is a common cause of death in children and young adults, is important for injury management. Neuroinflammation is responsible for both primary and secondary brain injury, and C-reactive protein-albumin ratio (CAR) has allowed use of biomarkers such as procalcitonin (PCT) in predicting mortality. Here, we compared the performance of CAR and PCT in predicting ICU mortality in TBI.MethodsAdults with TBI were enrolled in our study. The medical records of 82 isolated TBI patients were reviewed retrospectively.ResultsThe mean patient age was 49.0 ± 22.69 years; 59 of all patients (72%) were discharged, and 23 (28%) died. There was a statistically significant difference between PCT and CAR values according to mortality (P<0.05). The area under the curve (AUC) was 0.646 with 0.071 standard error for PCT and 0.642 with 0.066 standard error for CAR. The PCT showed a similar AUC of the receiver operating characteristic to CAR. ConclusionsThis study shows that CAR and PCT are usable biomarkers to predict ICU mortality in TBI. When the determined cut-off values are used to predict the course of the disease, the CAR and PCT biomarkers will provide more effective information for treatment planning and for preparation of the family for the treatment process and to manage their outcome expectations.

C-reactive protein/albumin ratio and Glasgow prognostic score are associated with prognosis and infiltration of Foxp3+ or CD3+ lymphocytes in colorectal liver metastasis

BackgroundInflammatory indices and tumor-infiltrating lymphocytes (TILs) have prognostic value in many cancer types. This study aimed to assess the prognostic value of inflammatory indices and evaluate their correlation with survival and presence of TILs in patients with colorectal liver metastasis (CRLM).MethodsMedical records of 117 patients who underwent hepatectomy for CRLM were retrospectively reviewed. We calculated inflammatory indices comprising the neutrophil/lymphocyte ratio, platelet/lymphocyte ratio, C-reactive protein/albumin ratio (CAR), and Glasgow prognostic score (GPS). Furthermore, we evaluated the relationship between these ratios and the GPS and survival rates and immunohistochemical results of tumor-infiltrating CD3+, CD8+, and Foxp3+ lymphocytes.ResultsThe patients with low CAR values and low GPS had significantly better overall survival as per the log-rank test (p = 0.025 and p = 0.012, respectively). According to the multivariate analysis using the Cox proportional hazard model, the CAR (hazard ratio [HR], 0.57; 95% confidence interval [CI], 0.33–0.99; p = 0.048) and GPS (HR, 0.40; 95% CI, 0.19–0.83; p = 0.013) were independent prognostic factors. Additionally, Foxp3+ lymphocytes were more common in samples from the patients with a low CAR (p = 0.041). Moreover, the number of CD3+ TILs was significantly higher in the patients with a low GPS (p = 0.015).ConclusionsThe CAR and GPS are simple, inexpensive, and objective markers associated with predicting survival in patients with CRLM. Moreover, they can predict the presence of Foxp3+ and CD3+ lymphocytes in the invasive margin of a tumor.Trial registrationRetrospectively registered. https://www.kurume-u.ac.jp/uploaded/attachment/14282.pdf.

Is the С-reactive protein/albumin ratio a prognostic factor in children with peripheral facial paralysis?

BACKGROUND: Bells Palsy (BP), accepted as an idiopathic condition and for which inflammation is believed to have a role in the pathogenesis, is a disease characterized by acute unilateral weakness in facial muscles innervated by the facial nerve.&#x0D; AIM: This study aimed to examine the relationship between the C-reactive protein/albumin ratio (CAR) and hematological parameters including the neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), mean platelet volume (MPV), and red cell distribution width (RDW) in children with BP.&#x0D; MATERIALS AND METHODS: The study included 65 children diagnosed with idiopathic peripheral facial paralysis and a control group of 49 healthy children. The patients were classified into two groups according to the House-Brackmann (HB) grade at the time of diagnosis, as mild (HB grade 23) and severe (HB grade 45). Patients evaluated as HB grade 1 with normal, healthy, and symmetrical muscle function were not included in the study. The children in the patient group were classified into three groups at the end of a six-month follow-up period as full recovery, partial recovery, and no recovery. The patient and control groups were compared according to the CAR, NLR, PLR, MPV, and RDW values. After treatment, the full recovery and no recovery groups were compared based on the CAR, NLR, PLR, MPV, and RDW values.&#x0D; RESULTS: The NLR was found to be significantly higher in the BP patient group than in the control group (p 0.001). There was also a significant difference in the NLR value between the full recovery and no recovery groups. No statistically significant difference was found between the patient and control groups or between the full recovery and no recovery groups in terms of the CAR, PLR, MPV and RDW values.&#x0D; CONCLUSIONS: NLR, an easily accessed hematological parameter, may be used as a marker of poor prognosis in pediatric patients with BP. CAR was of no prognostic value in pediatric BP patients.

The Value of the C-Reactive Protein/Albumin and Fibrinogen/Albumin Ratios in Predicting Disease Severity and Mortality in Elderly COVID-19 Patients

Objective: Due to the high mortality levels associated with the novel coronavirus, reliable predictors for determining disease mortality and severity are needed to permit the careful allocation of health services and for earlier clinical intervention and follow-up. The purpose of this study was to determine the predictive value of the C-reactive protein (CRP)/albumin ratio (CAR) and the fibrinogen/albumin ratio (FAR) in determining mortality and evaluate correlations between these values and thoracic computed tomography (CT) findings. Material and Methods: COVID-19 patients aged over 65 presenting to the emergency department of a tertiary training and research hospital between Oct 15, 2021, and Jan 15, 2022, were examined in this single-center, retrospective study. The study population was established based on inclusion and exclusion criteria. The patients’ mortality status and pulmonary involvement percentages were compared with their laboratory parameters. Results: The relationships between patients’ CAR and FAR values and mortality and disease severity were investigated. Cut-off points of 3.0 for CAR (AUC 0.767, sensitivity 76.5% and specificity 70.1%) and 14.4 for FAR (AUC 0.731, sensitivity 75.0% and specificity 69.0%) were determined for the prediction of mortality. In terms of prediction of disease severity, cut-off points were 4.2 for CAR (AUC 0.786, sensitivity 73.7%, and specificity 75.2%) and 15.2 for FAR (AUC 0.789, sensitivity 84.2%, and specificity 69.6%). Conclusion: Based on our study findings, CAR and FAR values may be useful in the early differentiation of mortality and pulmonary parenchymal involvement in elderly COVID-19 patients.
