Correlation of Enhancement Degree on Contrast-enhanced Ultrasound with Histopathology of Carotid Plaques and Serum High Sensitive C-Reactive Protein Levels in Patients Undergoing Carotid Endarterectomy

This study was undertaken to investigate the correlation of the enhancement degree on contrast-enhanced ultrasound(CEUS) with the histopathology of carotid plaques and the serum high sensitive C-reactive protein(hs-CRP) levels in patients undergoing carotid endarterectomy(CEA). Carotid CEUS was performed preoperatively in 115 patients who would undergo CEA, and the enhancement degree of the carotid plaques was evaluated by both the visual semiquantitative analysis and the quantitative time-intensity curve analysis. Serum hs-CRP levels were detected using the particle-enhanced immunoturbidimetric assay also before the operation. Additionally, the carotid plaque samples were subjected to histopathological examination postoperatively. The density of neovessels and the number of macrophages in the plaques were assessed by immunohistochemistry. The results showed that among the 115 patients, grade 0 plaque contrast enhancement was noted in 35 patients, grade 1 in 48 patients and grade 2 in 32 patients. The degree of plaque enhancement, the density of neovessels, the number of macrophages, and the hs-CRP levels were highest in the grade 2 patients. Correlation analysis showed that the enhancement degree of the carotid plaques was closely related to the immunohistochemical parameters of the plaques and the serum hs-CRP levels. It was suggested that the carotid plaque enhancement on CEUS can be used to evaluate the vulnerability of carotid plaques.

Responses of serum inflammatory factor high-sensitivity C-reactive protein, interleukin-6, and tumor necrosis factor-alpha in elderly males with cerebral infarction Non-randomized concurrent control

BACKGROUND： Cerebral infarction is poorly treated due to neuronal necrosis and secondary pathophysiological changes; for example, free radical production and inflammatory reactions. OBJECTIVE： To detect the levels of high-sensitivity C-reactive protein （hs-CRP）, interleukin-6 （IL-6）, and tumor necrosis factor- a （TNF- α ） in elderly males with cerebral infarction. DESIGN： Non-randomized current control study. SETTING： Cadre Medical Department, Guizhou Provincial People＇s Hospital. PARTICIPANTS： Forty elderly males （65-89 years old） with cerebral infarction were selected from Cadre Medical Department, Guizhou Provincial People＇s Hospital from February 2004 to December 2006. All patients met the diagnostic criteria of cerebral infarction modified at the 4th National Cerebrovascular Disease Academic Meeting, and were diagnosed on the basis of CT or MRI tests. Furthermore, 35 elderly male inpatients （65-87 years old） without cerebral infarction were selected as the control group. Included subjects provided confirmed consent and did not have heart disease, diabetes mellitus, lipid disorder, acute trauma, infection, rheumatism, or other inflammatory diseases. The study was approved by the local ethics committee. There were no significant differences in age, blood pressure, and lipid levels between the cerebral infarction group and the control group （P 〉 0.05）, and this suggested that the baseline data of both groups were comparable. METHODS： Fasting venous blood was drawn from cerebral infarction patients 24 hours after cerebral infarction attack and from control subjects 24 hours after hospitalization. A latex-enhanced immunoturbidimetric assay and an enzyme-linked immunosorbent assay were used to detect the levels of hs-CRP, IL-6, and TNF- α in the serum. MAIN OUTCOME MEASURES： The levels of hs-CRP, 1L-6, and TNF- α in the serum in both groups. RESULTS： Forty cerebral infarction patients and thirty-five control subjects were included in the final analysis without any loss. Levels of hs-CRP, IL-6, and TNF-α in the cerebral infarction group were significantly higher than those in the control group （P 〈 0.01 ）. CONCLUSION： Levels of serum inflammatory reactive factors are increased in elderly males with cerebral infarction.

Relationship of High Sensitivity C-Reactive Protein with Cardiovascular, Diabetic, and Hepatic Biomarkers

Biomarkers are early predictors of various disorders, circulating level of C-reactive protein is a sensitive biomarker of systemic inflammation and may also be associated with the development of diabetic, hepatic, and cardiovascular diseases. In the present study, we aimed to investigate the association between circulating levels of high sensitive C-reactive protein (hs-CRP) and various biomarkers for hepatic, diabetic, and cardiovascular health. The retrospective analysis included 438 individuals who were tested for these panels simultaneously at Vibrant America Clinical Laboratory. The study population included free-living individuals without any preexisting clinical conditions. Among the cardiovascular markers, a positive correlation and significant association was found between high levels of hs-CRP and serum levels of triglycerides (r = 0.0964, p −0.1423, p −0.1216, p < 0.0105) with circulating levels of hs-CRP. Among all the diabetic markers, glucose (r = 0.1547, p < 0.0011) and glycated serum protein (r = 0.1725, p < 0.0003) were positively correlated with circulating hs-CRP. In the hepatic panel, AST, a transaminase that plays a vital role in amino acid metabolism, was found to have a strong positive correlation with hs-CRP (r = 0.2139, p < 0.0001). In conclusion, the results clearly show the association of hs-CRP with diabetic, hepatic, and cardiovascular risk factors indicating its central value as a key marker for several lifestyle-associated disorders.

Myeloperoxidase and High-Sensitivity C-Reactive Protein for Predicting Major Adverse Cardiovascular Events in Patients with Coronary Heart Disease

Background: Research has shown that high-sensitivity C-reactive protein (hs-CRP) is a major inflammatory marker for prediction of acute coronary syndrome (ACS). Myeloperoxidase (MPO) also plays an important role in atherosclerosis initiation and development. In present study, the major adverse cardiovascular events (MACEs) of patients with coronary heart disease (CHD) were investigated. Methods: MPO, hs-CRP and ACS-related risk factors from 201 ACS (78 AMI and 123 UAP) and 210 non-ACS (84 SAP and 126 non-CHD) patients confirmed by coronary angiography were detected, and the data were analyzed with receiver operating characteristic (ROC) curve and Spearman’s correlation coefficients. MACEs of 285 CHD patients were investigated during the 4-year period follow-up from March 2010 to May 2014. Results: The areas under ROC curve for diagnosing ACS were 0.888 (95% CI 0.843 - 0.933) for MPO, and 0.862 (95% CI 0.815-0.910) for hs-CRP, respectively. There were significantly correlations between MPO and hs-CRP in both ACS and non-ACS groups. Regarding to ACS patients, both MPO and hs-CRP were positively correlated with BMI, TC, TG, LDL-C and Hcy. Prospective study demonstrated that the incidences of MACEs associated significantly with elevated MPO baseline level (yes vs no, OR 7.383, 95% CI 4.095 - 13.309) and high hs-CRP baseline level (yes vs no, OR 4.186, 95% CI 2.469 - 7.097) in CHD patients. Conclusions: The present study provides the epidemiological evidence that elevated baseline MPO and hs-CRP levels are both valuable predictors of MACEs in CHD patients. MPO and hs-CRP would prompt the progression of atherosclerosis and development from SAP to ACS.

High Sensitivity C-Reactive Protein Associated with Different Health Predictors in Middle-Aged and oldest old Chinese

Objective To describe the distribution of plasma high sensitivity C-reactive protein （hsCRP） and explore the relationship between hsCRP and metabolic risk factors among residents living in longevity areas of China. Methods 268 individuals aged between 40 and 59 years and 506 individuals aged over 90 years were selected from 5 longevity areas of China to participate in a cross section longitudinal cohort study. The participants were interviewed with general health related questionnaire to collect their demographic, behavioral and lifestyle data, as well as their chronic conditions, and meanwhile their physical and biomedical parameters including waist circumference （WC）, blood pressure （BP）, hsCRP, plasma lipids, and fasting blood glucose （FBG） were measured. Results The median of hsCRP was 0.99 mg/L in the middle-aged group and 2.76 mg/L in the oldest old group. No significant gender difference was observed between the above two groups. Among the oldest old individuals, 36.56% had an hsCRP level 〉3.0 mg/L. The prevalence of high hsCRP was 26.79% in the middle-aged group. The results of stepwise multiple linear regression analyses showed that HDL-C was independently associated with In （hsCRP） concentration in the middle-aged group, whereas In （TG）, HDL-C and FBG were correlated after adjustment for gender, study site, smoking, drinking, education and BMI in the oldest old group. Conclusion HDL-C is a stronger predictor of elevated hsCRP than other metabolic factors in the middle-aged population. For the oldest old persons, high TG, low HDL-C, and FBG predict elevated plasma hsCRP.

Clinical application of neutrophil/lymphocyte ratio combined with high sensitive C reactive protein in evaluation of community acquired pneumonia

Objective:To explore the application value of neutrophil/lymphocyte ratio (NLR) combined with high sensitive C reactive protein (hs-CRP) in the evaluation of community acquired pneumonia (CAP). Methods:From November 2015 to October 2016, 58 cases of CAP patients admitted in our department were selected as research objects and were divided into low risk group and high risk group according to the PSI score and CURB-65 standard for evaluation. They were divided into improved group (48 cases) and death group (10 cases) according to prognosis. Hs-CRP was determined by immunoturbidimetric assay, procalcitonin (PCT) by immunofluorescence, NLR by count method of laser scattering, and white blood (WBC) was counted. The differences in WBC, PCT, NLR and hs-CRP between different risk groups were compared, and the correlation was evaluated using Spearman's rank correlation analysis method. The changes in indexes were observed in the improved and death cases. Results:The high risk group had higher NLR, PCT and hs-CRP than low risk group (P<0.05), while no significant difference was found in WBC (P>0.05). No correlation was found between NLR and WBC, while a strong correlation was found between hs-CRP and PCT. The WBC, PCT, NLR and hs-CRP levels were significantly lower in the improved group than the death group (P<0.05). Conclusions:NLR combined with hs-CRP, WBC, and PCT has a good assessment of the severity of CAR, and high levels of NLR, hs-CRP, WBC, and PCT predict the severity of the disease and poor prognosis.

Elevated IL-37 levels in the plasma of patients with severe coronary arterycalcification

Background Coronary artery calcification （CAC） is a predictor of cardiovascular events and plaque burden and is closely associatedwith chronic inflammation. Intedeukin （IL）-37 is a newly discovered member of the IL-1 family and is considered an anti-inflammatorycytokine. Our recent study on mice indicated that IL-37 could attenuate atherosclerosis and vascular calcification, which suggests that IL-37could be associated with the development of atherosclerosis and related diseases. The aim of this study was to investigate if IL-37 plays arole in the progression of CAC in patients. Methods Two hundred participants with suspected cardiovascular disease were recruited. Thelevels of plasma IL-37, osteoprotegerin （OPG）, hypersensitive C-reactive protein （hsCRP） together with other biochemical parameters weremeasured, and a coronary calcium assessment was carried out by multi-detector row CT. A score of 〈 10 AU （Agatston units） denotes anabsence of CAC, a score of 11-100 AU denotes mild CAC, 101-400 denotes moderate CAC, and 〉 400 AU denotes severe CAC. ResultsOur initial data showed that there were no apparent differences in plasma IL-37 levels among patients with or without mild or moderate CAC.However, IL-37 levels were significantly increased in patients with severe CAC （P 〈 0.001）. Similar results were observed for plasma OPGand hsCRP levels. When IL-37 levels in patients with severe calcification were compared with that in all of the other non-severe CAC groups,it became apparent that there was a significant positive correlation between IL-37 level and severe CAC （r = 0.360, P 〈 0.001; OR = 1.033）using Spearrnan＇s correlation and binary logistic regression analysis. Conclusions This study demonstrates that the anti-inflammatory cy-tokine IL-37 is associated with high coronary calcium levels, suggesting that IL-37 expression may be caused by the activation ofinf/amma-tion and that IL-37 might become a predictor of severe CAC in the future, which requires further investigation.

Associations of plasma homocysteine and high-sensitivity C-reactive protein levels with arterial stiffness in Chinese population： a community-based study

Background Arterial stiffness increases with age and is also associated with traditional cardiovascular risk factors. Little is known about the relations of homocysteine and high-sensitivity C-reactive protein （hs-CRP） to arterial stiffness in the Chinese community. The aim of the present study was to investigate the association of plasma homocysteine and hs-CRP levels with arterial stiffness in a community-based cohort. Methods We related levels of homocysteine and hs-CRP to four measures of arterial stiffness （carotid-femoral pulse wave velocity （PWV）, carotid-radial PWV, carotid-ankle PWV and heart rate corrected augmentation index） in 1680 participants from two communities of Beijing, China. Arterial stiffness was measured within two days of the time of biomarker measurement. Results In univariate analysis, homocysteine was positively associated with the carotid-femoral PWV （r=0.211, P 〈0.0001）, carotid-radial PWV （r=0.120, P 〈0.0001） and carotid-ankle PWV （r=0.148, P 〈0.0001）, whereas it was inversely related to the augmentation index （r= -0.052, P=0.016）. Hs-CRP was positively associated with the carotid-femoral PWV （r=0.074, P=0.001） and carotid-ankle PWV （r=0.050, P=0.02）. In multiple-adjusted models （R2=0.57）, homocysteine levels remained a significant determinant of the carotid-femoral PWV （standardized 13=0.065, P=0.007）, whereas the association of hs-CRP with measurements of arterial stiffness was not present. Conclusions In the Chinese population, plasma homocysteine levels are associated with alterations of aortic stiffness, whereas plasma levels of hs-CRP are not independently related to artery stiffening.

目的探讨不同程度儿童1型糖尿病酮症酸中毒血清高敏-C反应蛋白(high-sensitivity C-reactive pro-tein,hs-CRP)、白细胞介素-10(interleukin-10,IL-10)、免疫球蛋白E(serum immunoglobulin E,IgE)、中性粒细胞与淋巴细胞比值(neutrophil to lymphocyte ratio,NLR)水平的相关性。方法回顾性选取2022年1月—2023年5月淄博市妇幼保健院收治的52例儿童1型糖尿病酮症酸中毒患儿的临床资料,进行血清hs-CRP、IL-10、IgE、NLR检测,对检测结果进行相关性分析。结果重度酮症酸中毒患儿血清hs-CRP、IL-10高于轻度、中度患儿,IgE水平低于轻度、中度患儿,差异有统计学意义(P均<0.05)。儿童1型糖尿病酮症酸中毒的严重程度与血清hs-CRP、IL-10呈正相关,与IgE呈负相关(P均<0.05);与NLR无相关性(P>0.05)。结论对于儿童1型糖尿病酮症酸中毒的诊断中,血清hs-CRP、IL-10、IgE均发挥重要作用,NLR对于细菌感染的判断具有积极作用,可更好的对疾病进行诊断,同时监控疾病进展,是诊断和评估病情变化的重要指标。

急性脑梗死患者外周血hs-CRP、WBC、NEU、HCY表达及其临床意义

目的 探究急性脑梗死(ACI)患者外周血超敏C反应蛋白(hs-CRP)、白细胞计数(WBC)、中性粒细胞(NEU)、同型半胱氨酸(HCY)表达及其临床意义。方法 选取2021年8月—2023年1月本院收治的120例ACI患者作为研究对象(ACI组),根据美国国立卫生研究院卒中量表(NIHSS)将ACI患者分为轻度组48例、中度组45例、重度组27例,根据患者6个月预后情况,分为预后良好组71例与预后不良组49例。同时选取同时期来我院体检的健康人员116例作为对照组,分别检测外周血hs-CRP、WBC、NEU、HCY水平,采用Spearman法分析ACI患者外周血hs-CRP、WBC、NEU、HCY水平与NIHSS评分的相关性;采用受试者工作特征(ROC)曲线分析外周血hs-CRP、WBC、NEU、HCY水平对ACI患者预后不良的预测价值。结果 与对照组比较,ACI组外周血hs-CRP、WBC、NEU、HCY水平显著升高(P<0.05)。轻度组、中度组、重度组外周血hs-CRP、WBC、NEU、HCY水平比较差异有统计学意义(P<0.05);且两两比较,差异均有统计学意义(P<0.05)ACI患者外周血hs-CRP、WBC、NEU、HCY水平与NIHSS评分呈正相关(r=0.583、0.600、0.457、0.585,P<0.05)。ACI预后不良组患者外周血hs-CRP、WBC、NEU、HCY水平显著高于预后良好组(P<0.05)。hs-CRP、WBC、NEU、HCY水平单独与联合预测ACI患者预后不良的曲线下面积(AUC)分别为0.770、0.811、0.851、0.633、0.934,联合预测价值高于单独预测(P<0.05)。结论 hs-CRP、WBC、NEU、HCY在ACI患者外周血水平升高,与患者病情发生发展、预后评估有关,可以作为ACI病情诊断、治疗及预后评估的标志物。

hs-CRP、Fg、ALP、WBC水平对骨伤术后感染的诊断分析

目的:分析超敏C反应蛋白(hypersensitive C-reactive protein,hs-CRP)、纤维蛋白原(Fibrinogen,Fg)、碱性磷酸酶(Alkaline phosphatase,ALP)、白细胞计数(White blood cell count,WBC)水平对骨伤术后感染的诊断价值。方法:选择我院在2021年7月-2022年7月期间收治的骨伤术后发生感染的患者48例为观察组,另选择同时期进行骨伤手术但未发生感染的患者49例为对照组,对比2组患者血清hs-CRP、Fg、ALP、WBC水平,对比感染前后观察组hs-CRP、Fg、ALP、WBC水平,并计算血清因子的诊断价值。结果:感染与时间对hs-CRP、Fg、ALP及WBC水平具有交互作用,差异有统计学意义(P<0.05)。治疗完成首次复查时,观察组血清hs-CRP、Fg、ALP、WBC水平较治疗前相比有所下降,差异有统计学意义(P<0.05)。ROC曲线分析结果显示,hs-CRP、Fg、ALP以及WBC诊断骨伤术后患者感染的曲线下面积(Area under curve,AUC)分别为0.964、0.929、0.913、0.798。其中,hs-CRP的AUC最大,为0.964,最佳临界值为3.81,灵敏度为87.50%、特异度为93.70%,但ROC结果显示,WBC及Fg的特异度更高,均为97.90%,因此研究认为结合hs-CRP、Fg、ALP及WBC四项指标进行联合检测的效果更佳。结论:针对骨伤手术术后感染患者实施联合hs-CRP、Fg、ALP、WBC指标检测的诊断价值更高,且对患者后续的疗效观察具有较好的临床应用价值,值得推广。
