Background Both C-reactive protein (CRP) level and neutrophil-to-lymphocyte ratio (NLR) are commonly elevated in patients with asthma. It is necessary to develop a novel marker, the combined score of CRP level and NLR (C-NLR score) based on cutoff points of CRP and NLR, and apply it in asthma diagnosis. The aim of this study was to explore whether C-NLR could distinguish children with exacerbated asthma. Methods Children suffering from exacerbated asthma were regarded as the asthmatic group ( n = 86), which was divided into three groups: mild ( n = 54), moderate ( n = 17), and severe ( n = 15). The control group consisted of children without any allergic disease and infection ( n = 38). To compare CRP level and NLR between the asthmatic group and control group, a receiver-operating characteristic curve was constructed to determine area under the curve (AUC) and optimal cutoff point. Thereafter, the C-NLR score was classified as follows: C-NLR score of 2 with an elevated CRP level and high NLR, a C-NLR score of 1 with one of these abnormalities, and a C-NLR score of 0 with a normal CRP level and low NLR. The C-NLR score was then compared among different asthma groups. Results In the control group, the CRP level and NLR were 1.9 (0.5–2.6) mg/L and 1.01 (0.69–1.31), respectively. In the asthmatic group, the CRP level and NLR were 7.3 (3.2–14.2) mg/L and 3.08 (1.73–5.34), respectively, which were higher than those in the control group ( p < 0.001 for CRP and p < 0.001 for NLR). The AUC of CRP was 0.86, and the optimal cutoff point was 3.6 mg/L. The AUC of NLR was 0.86, and the optimal cutoff point was 1.72. The AUC of the C-NLR score was 0.94, and the optimal cutoff point was 1. Conclusions C-NLR, a novel inflammatory marker, was applied here for the exacerbated asthma for the first time. Our study has shown C-NLR is a promising marker to distinguish children with exacerbated asthma from healthy children.

Background:C-reactive protein to albumin ratio (CAR) has emerged as a significant biomarker to evaluate and predict systemic inflammation[1]. However, the role of CAR in patients with axial spondyloarthritis (axSpA) remains unknown.Objectives:The aim of this study was to investigate the relationship between CAR and disease activity of axSpA.Methods:A total of 241 patients and 61 healthy controls from Guangdong Second Provincial General Hospital from December 2015 to August 2019 were retrospectively recruited in this study. Patients were divided into two groups, with 176 patients in remission group (BASDAI<4) and 65 patients in active group (BASDAI≥4). Erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), albumin (ALB), CAR, neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR) and monocyte-lymphocyte ratio (MLR) were detected. The correlations between CAR, NLR, PLR, MLR and disease activity were analyzed by the Spearman’s correlations analysis. Receiver operation characteristic (ROC) curves were performed to evaluate the discriminative utility of these parameters for disease activity of axSpA. Furthermore, the evaluation of the risk factors of axSpA was conducted using binary logistic regression analysis.Results:CAR, ESR, CRP, NLR, PLR and MLR in axSpA patients were significantly higher than those in the control group (p<0.05 for each), while ALB was significantly lower (p<0.001). Similarly, CAR in remission group was higher than that in control group (p<0.001) and was lower than that in active group (p<0.001). Besides, there were significantly positive correlations between CAR and ESR (r=0.702, P<0.001), CRP (r=0.996, P<0.001), BASDAI (r=0.329, p<0.001) and BASFI (r=0.328, P<0.001). Furthermore, ROC suggested that the area under the curve (AUC) of CAR was 0.701, which was the highest. The optimal cutoff point of CAR was 0.3644, with sensitivity and specificity of 58.5% and 79.0%. Logistic analysis results revealed that elevated CAR and MLR were independent risk factors for axSpA (EXP (B) =15.546, 95%CI: 5.898-40.979, P<0.001; EXP (B) =2.206, 95%CI: 1.077-4.519, P=0.031, respectively).Conclusion:CAR was increased in axSpA patients especially in active group, and significantly correlated with disease activity. CAR may serve as a novel inflammatory marker of monitoring disease activity in patients with axSpA.References:[1]He, Y., et al., Correlation between albumin to fibrinogen ratio, C-reactive protein to albumin ratio and Th17 cells in patients with rheumatoid arthritis.

Abstract Objectives A tension headache is the most common type of headache, and its causes are multifactorial. A relationship has been shown between migraine headaches and neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and C-reactive protein (CRP). In this study, we investigated the NLR, PLR, and serum CRP levels in frequent episodic tension-type headache (FETTH) and chronic tension-type headache (CTTH) patients. Materials and Methods This retrospective study included 64 patients with FETTH, 80 patients with CTTH, and 60 healthy controls who were followed up in the neurology clinic. Hematological parameters were compared between the patient and control groups. Results In CTTH patients, platelets, NLR, PLR, and CRP values were statistically higher than in FETTH patients and patients in the control group. In FETTH patients, the PLR value was higher than in patients in the control group, but there was no statistically significant difference in NLR and CRP values between FETTH patients and patients in the control group. Also, there was no correlation between these values and age and gender. Conclusion Increase platelet count might have an effect on tension-type headache pathophysiology. Systemic inflammation parameters were shown to be significantly higher in CTTH patients. More comprehensive studies are needed to evaluate the effect of systemic inflammation on the chronicity of tension headaches.

BackgroundInflammation is widely considered an important hallmark of cancer and associated with poor postoperative survival. The objective of this study is to assess the significance of preoperative C-NLR, a new inflammation-based index that includes preoperative C-reactive protein (CRP) and neutrophil-to-lymphocyte ratio (NLR), on therapeutic outcomes for bladder cancer (BC) patients after radical cystectomy (RC).Materials and MethodsBC patients who underwent RC between 2010 and 2019 were retrospectively analyzed from our medical center. The predictive effect of CRP, NLR, and C-NLR on the survival of BC patients were analyzed by the receiver operating characteristic (ROC) curves. The relationship between C-NLR and postoperative survival was investigated by Cox regression. The corresponding nomograms were built based on the Cox regression results of overall survival (OS) and disease-free survival (DFS), which were further validated by ROC curves, decision curve analysis (DCA) curves, and calibration curves.ResultsOf the 199 eligible patients, 83 (41.70%) were classified as high C-NLR group and the remaining 116 (58.30%) were classified as low C-NLR group. ROC analysis showed that C-NLR had the largest area under curve (AUC) compared to CRP and NLR. Multivariate analysis revealed that T-stage and C-NLR [high C-NLR vs. low C-NLR, hazard ratio (HR) = 2.478, 95% confidence interval (CI), 1.538–3.993, p &lt; 0.001] were independent predictors of OS, whereas T-stage, M-stage, and C-NLR (high C-NLR vs. low C-NLR, HR = 2.817, 95% CI, 1.667–4.762, p &lt; 0.001) were independent predictors of DFS. ROC and DCA analysis demonstrated better accuracy and discrimination of 3- and 5-year OS and DFS with C-NLR-based nomogram compared to TNM stage. The calibration curve reconfirmed the accurate predicting performance of nomograms.ConclusionC-NLR is a reliable predictor of long-term prognosis of BC patients after RC and will contribute to the optimization of individual therapy for BC patients.

e15505 Background: Inflammation seems to be significant factor in carcinogenesis and tumor progression of numerous cancers. Blood calculated neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), C-reactive protein (CRP), lactate dehydrogenase (LDH), international normalized ratio (INR) can be evaluated as systemic inflammation markers and prognostic biomarker for many aims: survival outcomes, lymph node metastasis and recurrence, treatment responses in a variety of cancers. The purpose of this study was to investigate baseline associations between blood test parameters (NLR, PLR, LDH, CRP, INR) and their prognostic biomarker role for patient with metastatic gastric cancer, undergoing first-line chemotherapy Methods: Potential baseline inflammatory markers (platelets, neutrophils, lymphocytes, the platelet-lymphocyte ratio, the neutrophil-lymphocyte ratio, the serum C-reactive protein [CRP], the serum LDH, INR) were retrospectively analyzed in 32 patients with metastatic gastric cancer, IV stage (median of age – 60,50). Multivariate analyses were used to identify prognostic factors for overall survival (OS). Baseline values were compared with tumor characteristic and median survival times (MSTs). Results: Multivariate analysis identified due to Cox proportional-hazards regression showed significant longest OS in patients with: localization of primary tumor in antral part of gastric (HR 0,45, 95% CI 0,25-0,80, p = 0,0065); low baseline’s level of WBC (HR 1,17, 95% CI 1.02 - 1,35, p = 0,0219); low baseline’s level of neutrophil (HR 1,18, 95% CI 1.02 - 1,34, p = 0,0251). Level of LDH, CRP, INR didn’t show significant ratio for this cohort of patient. Peritoneum metastatic also didn’t significant affect on OS in patient with metastatic gastric cancer. Patients with low baseline’s platelet to lymphocyte ratio (HR 1,004, 95% CI 1,0009-1,0072, p = 0,0125) and low (from 0 to 3,0) neutrophil to lymphocyte ratio (HR 1,81, 95% CI 1,09-2,99, p = 0,0212) had a significantly longest OS time. Conclusions: Inflammatory markers can predict overall survival in stage IV gastric cancer. Simple and useful.
