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.展开更多

The aim of ...Metabolic syndrome (MetS) and its components have been linked to elevated serum levels of inflammatory biomarkers such as C-reactive protein, interleukin-6, interleukin-1β and tumor necrosis factor alpha. The aim of our study was to address the association between MetS components with serum hs-CRP and IL-6 levels among Congolese adults. A total of 357 participants (aged 30 - 87 years) were included in this cross-sectional study. Anthropometrics were collected and fasting blood sampled for assessment of fasting blood glycaemia (FBG), lipids and inflammatory parameters using commercially available assays. NCEP-ATPIII criteria were used to define MetS. The Median (IQR) hs-CRP and IL-6 levels were higher in participants with MetS than in those without ([7 (4, 14) versus 6 (4, 8)] mg/L;p = 0.092 and [23.8 (20.9, 27.6) versus 22.3 (19.5, 25.0)] pg/mL;p = 0.002). hs-CRP and IL-6 levels were significantly higher in females with MetS than in those without, but not in males. Among participants, only TG was correlated with hs-CRP (r = 0.149, p = 0.007), and a significant correlation was observed between TG (r = 0.116, p = 0.037), FBG (r = 0.208, p = 0.000), HDL-C (r = −0.119, p = 0.034) and SBP (r = 0.143, p = 0.010) and IL-6. In males, hs-CRP levels were positively correlated with TG (0.316;p = 0.000), negatively with HDL-C (r = −0.290, p = 0.0022), without such correlations in females. In Ames, IL-6 levels were positively correlated with FBG (r = 0.202;p = 0.035), and negatively with HDL-C (r = −0.249, p = 0.009). Significant correlations between IL-6 levels and FBG (r = 0.214;p = 0.000) or SBP (r = 0.227, p = 0.000) were observed in females. Logistic regression analysis was carried out to identify the relationship between MetS components and hs-CRP or IL-6. Values of area under receiver-operating characteristic (ROC) curves suggest potential use of serum hs-CRP (AUC = 0.675) and IL-6 (AUC = 0.656) as diagnostic biomarkers of MetS. Combination of hs-CRP and IL-6 improved diagnosis accuracy, yielding a 0.698 ROC curve area. MetS components are associated with hs-CRP and IL-6 levels among adults Congolese. Combining the two biomarkers hs-CRP and IL-6 improves Mets diagnostic accuracy compared to hs-CRP or IL-6 alone.展开更多

The vulnerability of coronary lesions in acute myocardial infarction(AMI) at the time of onset may be related to serum levels of C reactive protein(CRP) on admission, before CRP levels are affected by myocardial damage.Objective This study assessed the predictive value of CRP levels within six hours after the onset of acute anterior myocardial infarction with primary percutaneous coronary intervention(PCI).Methods The plasma CRP of 76 patients with first acute anterior myocardial infarction was measured within 6 hours after onset. They were divided into 2 groups: group 1( n =20) with elevated CRP( ≥0.3mg/dl ) on admission within 6 hours after onset and group 2( n =56) with normal CRP( <0.3mg/dl ) within 6 hours after onset. All patients were treated by primary PCI. The primary combined end points, including death due to cardiac causes, re MI related to the infarction artery(RIA) and repeat intervention of the RIA, and the restenosis rate were assessed in relation to CRP levels within 6 hours after onset. Left ventricular end diastolic volume index(EDVI),end systolic volume index(ESVI),and ejection fraction(EF) on admission and 6 month after the onset were assessed by left ventriculography. Changes in EDVI(ΔEDVI),ESVI(ΔESVI), and EF(ΔEF) were obtained by subtracting respective on admission values from corresponding 6 month follow up values. Results There were no significant differences in baseline characteristics between the two groups. The primary combined end points were significantly more frequent in group 1(20%) than those in group 2( 1.79% , P <0.01 ).In addition, restenosis rates were significantly higher in group 1 than in group 2(41.18% vs 16.07%, P<0.05). Group 1 showed greater increases in left ventricular volume and less improvement in EF compared with group 2(ΔEDVI 6.31 ±2.17 vs 3.29 ±9.46ml/m 2 , ΔESVI 5.92 ±2.31 vs 3.86 ±1.08ml/m 2 , ΔEF 1.92 ±0.47 vs 4.79 ±1.73% , P <0.05 , respectively).Conclusions CRP levels within 6 hours after the onset of AMI might predict adverse outcome after primary PCI and progressive ventricular remodeling within 6 month of AMI.展开更多

METHODS: The endpoints of antibiotic treatment in 46 patients with pyogenic liver abscess after complete percutaneous drainage were assessed by performing a retrospective study. After complete percutaneous drainage, normal CRP values were considered as the endpoint in 18 patients (experimental group), and normal body temperature for at least 2 wk were considered as the endpoints in the other 28 patients (control group). RESULTS:The duration of antibiotic treatment after complete percutaneous drainage was 15.83 ± 6.45 d and 24.25 ± 8.18 d for the experimental and the control groups, respectively (P=0.001), being significantly shorter in the experimental group than in the control group. The recurrence rate was 0% for both groups.However, we could not obtain the follow-up data about 3 patients in the control group. CONCLUSION: CRP values can be considered as an independent factor to determine the duration of the antibiotic treatment for pyogenic liver abscess after complete percutaneous drainage.展开更多

Methods A prospective cohort study was conducted among 2,589 participants from June 2002 to July 2012 in Inner Mongolia, China. The participants were categorized into 4 groups according to their level of ABSI and CRP. Cox proportional hazards models were used to assess the hazard ratios(HRs) and 95% confidence intervals(CIs) for ischemic stroke among all groups. Results The multivariate adjusted HRs(95% CI) of ischemic stroke for high ABSI and high CRP level were 1.46(0.89-2.39) and 1.63(0.95-2.79), respectively. Compared with the low ABSI/low CRP level group, the multivariate adjusted HRs(95% CI) of ischemic stroke in the low ABSI/high CRP, high ABSI/low CRP, and high ABSI/high CRP groups were 1.04(0.46-2.35), 1.06(0.58-1.95) and 2.52(1.27-5.00), respectively. The HR of ischemic stroke for the high ABSI/high CRP level group was the highest and most statistically significant. Conclusion We found that participants with simultaneously high ABSI and high CRP levels had the highest risk of ischemic stroke in the Mongolian population. Our findings suggest that the combination of high ABSI and high CRP levels may increase the risk of ischemic stroke.展开更多

Methods A total of 1450 NSTEMI patients were included in this study. Hs-CRP blood levels were measured via a turbidimetric immunoassay after confirming the diagnosis of NSTEMI with GRACE scores < 140. Results Consistent with prior studies, the MVA occurrence rate in our cohort was 6.7%, and patients with MVA exhibited a reduced left ventricular ejection fraction (46.1%± 6.9% vs. 61.5%± 8.7%, P = 0.032), a higher incidence of Killip classification > 1 (34.1% vs. 24.2%, P < 0.001), an increased surgical revascularization rate (34.1% vs. 9.7%, P < 0.001), and increased mortality (16.5% vs. 5.8%, P < 0.001). Serum hs-CRP levels were higher (P = 0.003) in NSTEMI patients with MVA, and this increase appeared unrelated to other clinical parameters. The C-statistic to discriminate MVA was 0.82 (95% CI: 0.74–0.89). Using receiver operating characteristics analysis, we optimized a cutoff point of 16 mL/L, and the sensitivity and specificity were 95% and 61%, respectively;the positive predictive value was 20% and the negative predictive value was 99%. Conclusions An hs-CRP assay is a potential MVA biomarker in low-risk NSTEMI patients with GRACE scores < 140. If validated in prospective studies, hs-CRP may offer a low-cost supplementary strategy for risk stratification for NSTEMI patients.展开更多

The underlying pathophysiologic mechanisms of this association have not been completely understood and may be multifactorial in origin. A number of studies suggest that inflammatory processes have emerged critical in the pathogenesis of CVD in OSAS. A range of circulating inflammatory molecules has been identified and measured, with a view to assess inflammation and predict vascular damage risk, such as plasma cytokines, adhesion molecules, and C-reactive protein(CRP). CRP is a relevant marker worthy of further study, because not only is elevated in patients with OSAS, but also is rapidly becoming a risk factor for cardiac disease. Furthermore, in selected OSAS patients, aggressive treatment of the disorder may lead to retarding or even improvement of CVD progression. However, still there is a debate on the true correlation between CRP and OSAS, as well as the clinical effect of any reduction after OSAS treatment. Further research is required to define those OSAS patients who will have a considerable reduction with treatment, as well as to understand the significance of the interaction between cardiovascular risk factor and CRP reduction in patients with OSAS.展开更多

文摘BACKGROUND Prompt and effective cardiopulmonary resuscitation(CPR)can promote the recovery of spontaneous circulation to some extent and can save patients’lives.The minimum target of cardiac resuscitation is the restoration of spontaneous circulation(ROSC).However,owing to prolonged sudden cardiac arrest,there is relatively high mortality within 24 h after cardiac resuscitation.Moreover,severe cerebral anoxia can deteriorate the prognosis of patients.Therefore,it is important to adopt an effective clinical evaluation of acute myocardial infarct(AMI)patients’prognosis after cardiac resuscitation for the purpose of prevention and management.AIM To investigate early CPR effects on human myeloperoxidase(MPO),soluble ST2(sST2),and hypersensitive C-reactive protein(hs-CRP)levels in AMI patients.METHODS In total,54 patients with cardiac arrest caused by AMI in our hospital were selected as the observation group,and 50 other patients with AMI were selected as the control group.The differences in serum levels of MPO,sST2,and hs-CRP between the observation group and the control group were tested,and the differences in the serum levels of MPO,sST2,and hs-CRP in ROSC and non-ROSC patients,and in patients who died and in those who survived,were analyzed.RESULTS Serum levels of MPO,sST2,hs-CRP,lactic acid,creatine kinase isoenzyme(CKMB),and cardiac troponin I(cTnI)were significantly higher in the observation group than in the control group(P<0.05).Serum levels of MPO,sST2,hs-CRP,lactic acid,CK-MB,and cTnI in the observation group were lower after CPR than before CPR(P<0.05).In the observation group,MPO,sST2,hs-CRP,lactic acid,CK-MB,and cTnI serum levels were lower in ROSC patients than in non-ROSC patients(P<0.05).MPO,sST2,hs-CRP,and lactic acid serum levels of patients who died in the observation group were higher than those of patients who survived(P<0.05).The areas under receiver operating characteristic curve predicted by MPO,sST2,hs-CRP,lactic acid,CK-MB,and cTnI were 0.616,0.681,0.705,0.704,0.702,and 0.656,respectively(P<0.05).The areas under receiver operating characteristic curve for MPO,SST2,hs-CRP,and lactic acid to predict death were 0.724,0.800,0.689,and 0.691,respectively(P<0.05).Logistic regression analysis showed that MPO,sST2,and hs-CRP were the influencing factors of ROSC[odds ratios=1.667,1.589,and 1.409,P<0.05],while MPO,sST2,hs-CRP,and lactic acid were the influencing factors of death(odds ratios=1.624,1.525,1.451,and 1.365,P<0.05).CONCLUSION Serum levels of MPO,sST2,hs-CRP,and lactic acid have a certain value in predicting recovery and prognosis of patients with ROSC.

文摘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.
文摘BACKGROUND Neonatal sepsis,a formidable threat to newborns,is a leading cause of neonatal mortality,with late-onset sepsis manifesting after 72 hours post-birth being particularly concerning.Pneumonia,a prevalent sepsis presentation,poses a significant risk,especially during the neonatal phase when lung defenses are compromised.Accurate diagnosis of pneumonia is imperative for timely and effective interventions.Saliva,a minimally invasive diagnostic medium,holds great promise for evaluating infections,especially in infants.AIM To investigate the potential of serum C-reactive protein(CRP),salivary CRP(sCRP),and mean platelet volume(MPV)as diagnostic markers for late-onset neonatal pneumonia(LONP).METHODS Eighty full-term neonates were systematically examined,considering anthropometric measurements,clinical manifestations,radiology findings,and essential biomarkers,including serum CRP,sCRP,and MPV.RESULTS The study reveals noteworthy distinctions in serum CRP levels,MPV,and the serum CRP/MPV ratio between neonates with LONP and healthy controls.MPV exhibited a robust discriminatory ability[area under the curve(AUC)=0.87]with high sensitivity and specificity at a cutoff value of>8.8.Correlations between serum CRP,sCRP,and MPV were also identified.Notably,sCRP demonstrated excellent predictive value for serum CRP levels(AUC=0.89),underscoring its potential as a diagnostic tool.CONCLUSION This study underscores the diagnostic promise of salivary and serum biomarkers,specifically MPV and CRP,in identifying and predicting LONP among neonates.These findings advocate for further research to validate their clinical utility in larger neonatal cohorts.

文摘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.
文摘BACKGROUND Complement overactivation is a major driver of lupus nephritis(LN).Impaired interactions of C-reactive protein(CRP)with complement factor H(CFH)have been shown as a pathogenic mechanism that contributes to the overactivation of complement in LN.However,genetic variations of neither CRP nor CFH show consistent influences on the risk of LN.AIM To examine whether genetic variations of CRP and CFH in combination can improve the risk stratification in Chinese population.METHODS We genotyped six CRP single nucleotide polymorphisms(SNPs)(rs1205,rs3093062,rs2794521,rs1800947,rs3093077,and rs1130864)and three CFH SNPs(rs482934,rs1061170,and rs1061147)in 270 LN patients and 303 healthy subjects.RESULTS No linkage was found among CRP and CFH SNPs,indicating lack of genetic interactions between the two genes.Moreover,CRP and CFH SNPs,neither individually nor in combination,are associated with the risk or clinical manifestations of LN.Given the unambiguous pathogenic roles of the two genes.CONCLUSION These findings suggest that the biological effects of most genetic variations of CRP and CFH on their expressions or activities are not sufficient to influence the disease course of LN.
文摘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.
文摘Metabolic syndrome (MetS) and its components have been linked to elevated serum levels of inflammatory biomarkers such as C-reactive protein, interleukin-6, interleukin-1β and tumor necrosis factor alpha. The aim of our study was to address the association between MetS components with serum hs-CRP and IL-6 levels among Congolese adults. A total of 357 participants (aged 30 - 87 years) were included in this cross-sectional study. Anthropometrics were collected and fasting blood sampled for assessment of fasting blood glycaemia (FBG), lipids and inflammatory parameters using commercially available assays. NCEP-ATPIII criteria were used to define MetS. The Median (IQR) hs-CRP and IL-6 levels were higher in participants with MetS than in those without ([7 (4, 14) versus 6 (4, 8)] mg/L;p = 0.092 and [23.8 (20.9, 27.6) versus 22.3 (19.5, 25.0)] pg/mL;p = 0.002). hs-CRP and IL-6 levels were significantly higher in females with MetS than in those without, but not in males. Among participants, only TG was correlated with hs-CRP (r = 0.149, p = 0.007), and a significant correlation was observed between TG (r = 0.116, p = 0.037), FBG (r = 0.208, p = 0.000), HDL-C (r = −0.119, p = 0.034) and SBP (r = 0.143, p = 0.010) and IL-6. In males, hs-CRP levels were positively correlated with TG (0.316;p = 0.000), negatively with HDL-C (r = −0.290, p = 0.0022), without such correlations in females. In Ames, IL-6 levels were positively correlated with FBG (r = 0.202;p = 0.035), and negatively with HDL-C (r = −0.249, p = 0.009). Significant correlations between IL-6 levels and FBG (r = 0.214;p = 0.000) or SBP (r = 0.227, p = 0.000) were observed in females. Logistic regression analysis was carried out to identify the relationship between MetS components and hs-CRP or IL-6. Values of area under receiver-operating characteristic (ROC) curves suggest potential use of serum hs-CRP (AUC = 0.675) and IL-6 (AUC = 0.656) as diagnostic biomarkers of MetS. Combination of hs-CRP and IL-6 improved diagnosis accuracy, yielding a 0.698 ROC curve area. MetS components are associated with hs-CRP and IL-6 levels among adults Congolese. Combining the two biomarkers hs-CRP and IL-6 improves Mets diagnostic accuracy compared to hs-CRP or IL-6 alone.

文摘Objective:To investigate the value of N-terminal pro B-type natriuretic peptide(NT-proBNP),high-sensitivity C-reactive protein(hs-CRP),and homocysteine(Hcy)levels in predicting cardiovascular events(CV)in patients with chronic heart failure(CHF).Methods:A total of 63 patients with CHF admitted to our hospital between June 2019 and July 2021 were selected.Their NT-proBNP,hs-CRP,and Hcy levels were detected at discharge,and a 12-month follow-up was done after their discharge to collect clinical data.The collected data were inclusive of data from 21 CHF patients with cardiovascular disease and 42 CHF patients without cardiovascular disease.The effect of NT-proBNP,hs-CRP,and Hcy levels on the occurrence of CV was analyzed.Results:The levels of NT-proBNP,hs-CRP,and Hcy in the group with cardiovascular disease were significantly higher than those in the group without cardiovascular disease(P<0.05);the levels of serum NT-proBNP,hs-CRP,and Hcy at discharge had certain value in predicting short-term CV in CHF patients(P<0.05).Conclusion:NT-proBNP,hs-CRP,and Hcy levels can be used to predict CV in CHF patients,thus having clinical application value.
文摘Background Increased levels of inflammatory markers have been documented in various settings of coronary artery disease. The vulnerability of coronary lesions in acute myocardial infarction(AMI) at the time of onset may be related to serum levels of C reactive protein(CRP) on admission, before CRP levels are affected by myocardial damage.Objective This study assessed the predictive value of CRP levels within six hours after the onset of acute anterior myocardial infarction with primary percutaneous coronary intervention(PCI).Methods The plasma CRP of 76 patients with first acute anterior myocardial infarction was measured within 6 hours after onset. They were divided into 2 groups: group 1( n =20) with elevated CRP( ≥0.3mg/dl ) on admission within 6 hours after onset and group 2( n =56) with normal CRP( <0.3mg/dl ) within 6 hours after onset. All patients were treated by primary PCI. The primary combined end points, including death due to cardiac causes, re MI related to the infarction artery(RIA) and repeat intervention of the RIA, and the restenosis rate were assessed in relation to CRP levels within 6 hours after onset. Left ventricular end diastolic volume index(EDVI),end systolic volume index(ESVI),and ejection fraction(EF) on admission and 6 month after the onset were assessed by left ventriculography. Changes in EDVI(ΔEDVI),ESVI(ΔESVI), and EF(ΔEF) were obtained by subtracting respective on admission values from corresponding 6 month follow up values. Results There were no significant differences in baseline characteristics between the two groups. The primary combined end points were significantly more frequent in group 1(20%) than those in group 2( 1.79% , P <0.01 ).In addition, restenosis rates were significantly higher in group 1 than in group 2(41.18% vs 16.07%, P<0.05). Group 1 showed greater increases in left ventricular volume and less improvement in EF compared with group 2(ΔEDVI 6.31 ±2.17 vs 3.29 ±9.46ml/m 2 , ΔESVI 5.92 ±2.31 vs 3.86 ±1.08ml/m 2 , ΔEF 1.92 ±0.47 vs 4.79 ±1.73% , P <0.05 , respectively).Conclusions CRP levels within 6 hours after the onset of AMI might predict adverse outcome after primary PCI and progressive ventricular remodeling within 6 month of AMI.
文摘BACKGROUND:Serum C-reactive protein(CRP) increases and albumin decreases in patients with inflammation and infection.However,their role in patients with acute pancreatitis is not clear.The present study was to investigate the predictive significance of the CRP/albumin ratio for the prognosis and mortality in acute pancreatitis patients.METHODS:This study was performed retrospectively with 192 acute pancreatitis patients between January 2002 and June 2015.Ranson scores,Atlanta classification and CRP/albumin ratios of the patients were calculated.RESULTS:The CRP/albumin ratio was higher in deceased patients compared to survivors.The CRP/albumin ratio was positively correlated with Ranson score and Atlanta classification in particular and with important prognostic markers such as hospitalization time,CRP and erythrocyte sedimentation rate.In addition to the CRP/albumin ratio,necrotizing pancreatitis type,moderately severe and severe Atlanta classification,and total Ranson score were independent risk factors of mortality.It was found that an increase of 1 unit in the CRP/albumin ratio resulted in an increase of 1.52 times in mortality risk.A prediction value about CRP/albumin ratio >16.28 was found to be a significant marker in predicting mortality with 92.1% sensitivity and 58.0% specificity.It was seen that Ranson and Atlanta classification were higher in patients with CRP/albumin ratio >16.28 compared with those with CRP/albumin ratio ≤16.28.Patients with CRP/albumin ratio >16.28 had a 19.3 times higher chance of death.CONCLUSION:The CRP/albumin ratio is a novel but promising,easy-to-measure,repeatable,non-invasive inflammationbased prognostic score in acute pancreatitis.

文摘Increased plasma total homocysteine (tHcy) and high sensitivity C-reactive protein (hsCRP) levels are independent risk factors for cardiovascular disease.However, the predictive value of tHcy in combination with hsCRP in patients with stroke is not known.To determine the relationship between tHcy and hsCRP, we enrolled 291 patients with first-onset stroke (196 ischemic and 95 hemorrhagic).Plasma tHcy and hsCRP levels were measured and subsequent vascular events and deaths were determined over a 5-year period.Using the arbitrary cutoff for tHcy (<18 μmol/L and ≥18 μmol/L) and hsCRP (<1 mg/L, 1-3 mg/L and >3 mg/L), the patients were divided into 6 groups.Survival analysis showed that the probability of death or new vascular events during a 5-year follow-up increased according to tHcy and hsCRP levels (P<0.01).The relative risk (RR) of death or new vascular events was 4.67 (95% CI, 1.96 to 11.14, P=0.001) in patients with high tHcy (≥18 μmol/L) and hsCRP (>3 mg/L) compared with those with low tHcy (<18 μmol/L) and hsCRP (<1 mg/L).The increased tHcy level (≥18 μmol/L) combined with increased hsCRP level (>3 mg/L) was still significantly associated with the risk of death or new vascular events (RR, 4.10, 95% CI, 1.61 to 10.45, P=0.003) even when adjusted for other risk factors at inclusion.The combination of increased tHcy and hsCRP levels had a stronger predictive value than increased hsCRP alone or increased tHcy level alone.Further studies are required to evaluate the potential decrease in risks associated with lowering both Hcy and hsCRP levels in patients that present with both increased tHcy and hsCRP.
文摘AIM:To investigate the clinical signifi cance of C-reactive protein (CRP) values in determining the endpoint of antibiotic treatment for liver abscess after drainage. METHODS: The endpoints of antibiotic treatment in 46 patients with pyogenic liver abscess after complete percutaneous drainage were assessed by performing a retrospective study. After complete percutaneous drainage, normal CRP values were considered as the endpoint in 18 patients (experimental group), and normal body temperature for at least 2 wk were considered as the endpoints in the other 28 patients (control group). RESULTS:The duration of antibiotic treatment after complete percutaneous drainage was 15.83 ± 6.45 d and 24.25 ± 8.18 d for the experimental and the control groups, respectively (P=0.001), being significantly shorter in the experimental group than in the control group. The recurrence rate was 0% for both groups.However, we could not obtain the follow-up data about 3 patients in the control group. CONCLUSION: CRP values can be considered as an independent factor to determine the duration of the antibiotic treatment for pyogenic liver abscess after complete percutaneous drainage.

文摘This study examined the role of high-sensitivity C-reactive protein (hsCRP), interleukin-6 (IL-6) and cystatin C in ischemic stroke complicating atrial fibrillation (AF) and the relationship of systemic inflammation with this disease in order to identify AF patients who are at high risk of stroke and need optimal anticoagulant therapy.A total of 103 AF patients, simple (n=75) or complicated by ischemic stroke (n=28), and 112 control subjects were recruited.IL-6 level was detected by using enzyme linked immunosorbent assay.Cystatin C and hsCRP levels were measured by means of a particle-enhanced immunonephelometric assay.The results showed that the AF patients had higher levels of hsCRP (P=0.004), IL-6 (P=0.000), and cystatin C (P=0.000) than control subjects.Plasma hsCRP level was increased in the AF patients with ischemic stroke as compared to the patients with simple AF (P=0.036).The AF patients who had the level of hsCRP exceeding 3.83 mg/L were at a higher risk than those with hsCRP level lower than 3.83 mg/L (P=0.030).After adjusting for other factors, cystatin C remained positively associated with IL-6 (r=0.613) and hsCRP (r=0.488).It was concluded that hsCRP is positively correlated with ischemic stroke complicating AF and may be a risk factor independent of other risk factors for AF.Elevated cystatin C level is also indicative of the increased risk of AF.

文摘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.

文摘Objective We aimed to evaluate the combined effects of a high body shape index(ABSI) and a high serum C-reactive protein(CRP) level on the incidence of ischemic stroke in a Mongolian population in China. Methods A prospective cohort study was conducted among 2,589 participants from June 2002 to July 2012 in Inner Mongolia, China. The participants were categorized into 4 groups according to their level of ABSI and CRP. Cox proportional hazards models were used to assess the hazard ratios(HRs) and 95% confidence intervals(CIs) for ischemic stroke among all groups. Results The multivariate adjusted HRs(95% CI) of ischemic stroke for high ABSI and high CRP level were 1.46(0.89-2.39) and 1.63(0.95-2.79), respectively. Compared with the low ABSI/low CRP level group, the multivariate adjusted HRs(95% CI) of ischemic stroke in the low ABSI/high CRP, high ABSI/low CRP, and high ABSI/high CRP groups were 1.04(0.46-2.35), 1.06(0.58-1.95) and 2.52(1.27-5.00), respectively. The HR of ischemic stroke for the high ABSI/high CRP level group was the highest and most statistically significant. Conclusion We found that participants with simultaneously high ABSI and high CRP levels had the highest risk of ischemic stroke in the Mongolian population. Our findings suggest that the combination of high ABSI and high CRP levels may increase the risk of ischemic stroke.

文摘C-reactive protein(CRP) is a biomarker of inflammation.Increased plasma levels of CRP are associated with an increased risk of myocardial infarction.However,the correlation between plasma CRP concentration and atherosclerotic plaque burden is poor.Based on these observations,it has been hypothesized that CRP increases the risk of myocardial infarction by promoting thrombosis.This article reviews available data that link enhanced CRP expression to increased risk of thrombosis,with a focus on the effects of CRP on hemostasis,platelet function,and fibrinolysis.Overall,the available data support the hypothesis that CRP is an important mechanistic link between inflammation and throm bosis.

文摘Objective To investigate whether C-reactive protein (CRP) is a biomarker of malignant ventricular arrhythmias (MVA) occurring in non-ST elevation myocardial infarction (NSTEMI) patients with Global Registry of Acute Coronary events (GRACE) scores < 140. Methods A total of 1450 NSTEMI patients were included in this study. Hs-CRP blood levels were measured via a turbidimetric immunoassay after confirming the diagnosis of NSTEMI with GRACE scores < 140. Results Consistent with prior studies, the MVA occurrence rate in our cohort was 6.7%, and patients with MVA exhibited a reduced left ventricular ejection fraction (46.1%± 6.9% vs. 61.5%± 8.7%, P = 0.032), a higher incidence of Killip classification > 1 (34.1% vs. 24.2%, P < 0.001), an increased surgical revascularization rate (34.1% vs. 9.7%, P < 0.001), and increased mortality (16.5% vs. 5.8%, P < 0.001). Serum hs-CRP levels were higher (P = 0.003) in NSTEMI patients with MVA, and this increase appeared unrelated to other clinical parameters. The C-statistic to discriminate MVA was 0.82 (95% CI: 0.74–0.89). Using receiver operating characteristics analysis, we optimized a cutoff point of 16 mL/L, and the sensitivity and specificity were 95% and 61%, respectively;the positive predictive value was 20% and the negative predictive value was 99%. Conclusions An hs-CRP assay is a potential MVA biomarker in low-risk NSTEMI patients with GRACE scores < 140. If validated in prospective studies, hs-CRP may offer a low-cost supplementary strategy for risk stratification for NSTEMI patients.
文摘Obstructive sleep apnea syndrome(OSAS) is a common medical condition, associated with atherosclerosis and cardiovascular disease(CVD). The underlying pathophysiologic mechanisms of this association have not been completely understood and may be multifactorial in origin. A number of studies suggest that inflammatory processes have emerged critical in the pathogenesis of CVD in OSAS. A range of circulating inflammatory molecules has been identified and measured, with a view to assess inflammation and predict vascular damage risk, such as plasma cytokines, adhesion molecules, and C-reactive protein(CRP). CRP is a relevant marker worthy of further study, because not only is elevated in patients with OSAS, but also is rapidly becoming a risk factor for cardiac disease. Furthermore, in selected OSAS patients, aggressive treatment of the disorder may lead to retarding or even improvement of CVD progression. However, still there is a debate on the true correlation between CRP and OSAS, as well as the clinical effect of any reduction after OSAS treatment. Further research is required to define those OSAS patients who will have a considerable reduction with treatment, as well as to understand the significance of the interaction between cardiovascular risk factor and CRP reduction in patients with OSAS.
