Relationships of High-sensitive C-reactive Protein ant P-wave Dispersion in Lone Atrial Fibrillation

Background： Current evidence links atrial fibrillation （AF） to the inflammation. Inflammatory indexes such as high-sensitive C-reactive protein （hs-CRP） have been related to the development and persistence of AF. However, the role of inflammation in the atrial electrophysiological remodeling indexed by P-wave dispersion （Pa） remains unclear. Methods： The study consisted of 71 patients with lone paroxysmal AF （AF group） and 71 age- and gender-matched controls of paroxysmal supraventricular tachycardia without history of AF （control group）. Electrocardiography, P hs-CRP, and other clinical characteristics were compared between the two groups. Results： There was no significant difference between the two groups regarding age, gender, hyperlipidemia, etc. Compared to controls, left atrial diameter （44 ± 7 vs 39 ± 7 mm）, Pd （49 ± 13 vs 26 ± 8 ms）, and hs-CRP （2.17 [1.46-2.89] vs 1.12 [0.74-1.41] rag/L） were increased （P 〈 0.05）, respectively. Linear regression identified hs-CRP as an independent correlation ofPd level both in the total population and the AF group （r = 0.464 and 0.313; P 〈 0.001, respectively）. Multiple logistic regression revealed hs-C RP as an independent determinant of AF （odds ratio [OR] =l 5.430, 95% confidence interval： 6.031-39.476： P 〈0.001）. Further adjusted tbr Pd, both Pd and hs-CRP were independent predictors for AF, but the OR for hs-CRP in predicting AF has been attenuated from 15.430 to 6.246. Conclusions： In lone AF, P and plasma hs-CRP concentration are inter-associated and related to AF. The interaction between hs-CRP and AF may be mediated by Pe, suggesting an important role of inflammation in the atrial electrophysiological remodeling predisposing to AF.

Negative Association of Circulating MicroRNA-126 with High-sensitive C-reactive Protein and Vascular Cell Adhesion Molecule-1 in Patients with Coronary Artery Disease Following Percutaneous Coronary Intervention

Background： Percutaneous coronary intervention （PCI） causes endothelial damage, resulting in an inflammatory response with elevation of markers such as high-sensitive C-reactive protein （hs-CRP） and vascular cell adhesion molecule-1（VCAM-1）, which are associated with restenosis after PCI. Evidence suggests that microRNA-126 （miR-126） plays an important role in vascular inflammation, but its correlation with PCl-mediated inflammation has not been investigated. In this study, we investigated the effect of PCI on circulating miR-126 and inflammation markers such as hs-CRP and VCAM-1. Methods： We enrolled 130 patients with coronary artery disease （CAD） in the Second Hospital of Jilin University from October 2015 to December 2015. Among them, 82 patients with CAD, defined as at least one major epicardial vessel with 〉70% stenosis who planned to undergo PCI, were divided into acute coronary syndrome （ACS） group （46 patients） and stable angina （SA） group （36 patients）. Forty-eight patients confirmed by coronary angiography without PCI were used as controls. The plasmas of all patients were collected prior to PCI and at 30 min, 24 h, and 72 h after PCI. The plasma VCAM-1 and hs-CRP were detected by enzyme-linked immunosorbent assay, and the miR-126 was evaluated by quantitative reverse transcription-polymerase chain reaction. Results： Plasma concentrations of hs-CRP and VCAM-I in patients with either ACS （n = 46） or SA （n = 36） were significantly higher than in controls （n = 48） （P 〈 0.01） prior to PCI, and increased further at 24 h and 72 h after PCI, compared with prior PCI. Moreover, VCAM-1 was positively correlated with balloon time and pressure. In contrast, the plasma concentration of miR-126 was significantly lower in patients with CAD than in controls, and further decreased with time post-PCl. A negative correlation was observed between miR-126 and hs-CRP and VCAM-1 at 72 h after PCI. Conclusion： There was a negative correlation of miR-126 with the PCI-induced markers of inflammation such as hs-CRP and VCAM-1.

Better understanding of c-reactive protein and leukocytes in psychiatric inpatients with affective disorders:A biopsychosocial approach

BACKGROUND Affective disorders(AD)have been linked to inflammatory processes,although the underlying mechanisms of this relationship are still not fully elucidated.It is hypothesized that demographic,somatic,lifestyle,and personality variables predict inflammatory parameters in AD.AIM To identify biopsychosocial factors contributing to inflammation in AD measured with two parameters,C-reactive protein(CRP)and leukocytes.METHODS This observational study investigated 186 hospital inpatients diagnosed with AD using demographic parameters,serum inflammatory markers,somatic variables,psychological questionnaires,and lifestyle parameters.Hierarchical regression analyses were used to predict inflammatory markers from demographic,somatic,lifestyle,and personality variables.RESULTS Analyses showed that 33.8%of the variance of CRP was explained by body mass index and other somatic medication(e.g.anti-diabetics),age and education,and age of affective disorder diagnosis.For leukocytes,20.1%of the variance was explained by smoking,diet,metabolic syndrome(MetS),and anti-inflammatory medication(e.g.non-steroidal anti-inflammatory drugs).Other psychiatric or behavioural variables did not reach significance.CONCLUSION Metabolic components seem important,with mounting evidence for a metabolic affective disorder subtype.Lifestyle modifications and psychoeducation should be employed to prevent or treat MetS in AD.

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

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

Salivary C-reactive protein and mean platelet volume as possible diagnostic markers for late-onset neonatal pneumonia

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.

Distribution of High-sensitivity C-reactive Protein Status in an Urban Population in China

Objectives To evaluate the distribution by age and sex of serum high-sensitivity C-reactive protein(hsCRP)in an urban Chinese population and to provide a profile prediction for the risk of bacterial infection,inflammatory diseases,or tissue damages in the body.Methods Serum hsCRP was determined using the Roche Tina-quant immuno-turbidimetric assay on a Hitachi 7600–010 automatic biochemical analyzer(Roche Diagnostics)in 1,572 males and 1,800 females,including 78 pregnant women,who were derived from the National Health and Nutrition Survey in2010–2012.Results The average hsCRP concentration in urban China was 0.68 mg/L for males and 0.65 mg/L for females.Significant differences in hsCRP were found among different age groups(P<0.05).Monitoring results showed no significant differences among the 6–11,45–59,and≥60-year-old groups in the comparison of hsCRP between males and females in large cities.However,hsCRP concentration was significantly higher in men aged 12–17 and 18–44 years than in women.Conclusion The distribution of the hsCRP status of residents in large cities in China was influenced by age and gender,and the hsCRP levels of both sexes increased gradually with age.In addition,hsCRP concentration was higher in healthy pregnant women than in non-pregnant women.Basing on our results,we recommend that this parameter be included in future national and international screening for early detection of various illnesses.

The Role of High-sensitivity C-reactive Protein, Interleukin-6 and Cystatin C in Ischemic Stroke Complicating Atrial Fibrillation

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.

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.

N-terminal pro-brain natriuretic peptide but not high-sensitivity C-reactive protein is related to severity of coronary artery stenosis in patients with acute coronary syndrome

Objective Biochemical indicators such as N-terminal pro-brain type natriuretic peptide（NT pro-BNP）and high-sensitivity Creactive protein（hsCRP）predict mortality in acute coronary syndrome（ACS）.However,little is known about the relationship of these factors with severity of coronary artery stenosis in patients with.Methods Three hundred and thirty-one subjects including 246 unstable angina pectoris patients and 85 myocardial infarction patients were recruited and classified into two groups：single-vessel disease group（1-vessel disease,n=93）and multiple-vessel disease group（≥2-vessels disease,n=238）according to selective coronary angiography.Plasma levels of NT pro-BNP and hsCRP were measured and severity of coronary stenosis was determined by Gensini score.Results NT pro-BNP but not hsCRP level was higher in patients with myocardial infarction than in patients with unstable angina pectoris.The patients with multiple-vessel disease had significantly higher NT pro-BNP level but not hsCRP compared with those with single-vessel disease.NT pro-BNP levels increased significantly as left ventricle（LV）function decreased,and only NT proBNP but not hsCRP level was related to Gensini score of severity of coronary stenosis in ACS.Conclusion NT proBNP but not hsCRP level is related to severity of coronary artery stenosis in patients in ACS.

The prognostic role of high-sensitivity C-reactive protein in patients with acute myocardial infarction

1 Introduction Inflammation is one of the main mechanisms in the pathogenesis of atherosclerosis,and the interest to the evaluation of inflammatory biomarkers in coronary artery disease(CAD)has been increasing over the last decade.[1,2]Destabilization of chronic artery plaques,which leads to acute coronary syndromes,has been associated with inflammatory status.[1,3]。

High-sensitivity C-reactive protein in paediatric inflammatory bowel disease

AIM:To study whether high-sensitivity C-reactive protein(hs-CRP) measurement can aid the assessment of disease activity and glucocorticoid treatment in paediatric inflammatory bowel disease(IBD).METHODS:CRP levels were measured in 39 children with IBD undergoing colonoscopy [median age 12.8 years,Crohn's disease(CD) n=20],in 22 other children with IBD followed for acute response to glucocorticoids,and in 33 paediatric non-IBD patients.When standard CRP level was below detection limit(<5mg/L),hs-CRP was analyzed.RESULTS:Sixty-four percent(25/39) of the children with IBD undergoing colonoscopy displayed undetectable(<5mg/L) standard CRP levels.Of these,the hs-CRP measurement could not differentiate between active(median,0.2 mg/L,range,0.007-1.37,n=17) or quiescent(0.1 mg/L,0.01-1.89,n=8,P=NS) disease.Patients with ileocolonic CD had higher CRP levels(14mg/L,0.06-45,n=13) than patients with no ileal involvement(0.18 mg/L,0.01-9,n=7,P<0.01) or ulcerative colitis(UC)(0.13 mg/L,0.007-23,P<0.05).In children with active IBD treated with systemic glucocorticoids,the standard CRP was undetectable in 59% of the patients.The hs-CRP levels did not differ between patients that responded to steroid therapy and in non-responders.CONCLUSION:The measurement of hs-CRP did not prove useful in the assessment of disease activity or glucocorticoid treatment in paediatric IBD patients that had undetectable standard CRP.

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.

Correlation between carotid atherosclerosis and serum high-sensitivity C-reactive protein in patients with cerebral infarction

BACKGROUND： Some researches demonstrate that high-sensitivity C-reactive protein may be a risk factor to cause carotid atherosclerosis in patients with cerebral infarction. Inflammatory reaction may participate in formation of carotid atherosclerosis in patients with acute cerebral infarction. OBJECTIVE： To investigate the correlation between levels of serum high-sensitivity C-reactive protein and carotid atherosclerosis in patients with acute cerebral infarction accompanied with carotid atherosclerosis. DESIGN： Contrast observation between two groups. SETTING： Department of Neurology, Zhenzhou Hospital, Shenyang Medical College. PARTICIPANTS： A total of 102 patients with acute cerebral infarction regarded as cerebral infarction group were selected from Department of Neurology, Shenzhou Hospital Affiliated to Shenyang Medical College from February 2005 to September 2006. There were 55 males and 47 females and their ages ranged from 55 to 86 years. All patients met the variously diagnostic points of cerebral infarction established by the Fourth National Cerebrovascular Disease Academic Meeting and were finally diagnosed with CT or MRI examination. Illness course was in an acute phase. A total of 96 healthy subjects were regarded as control group, including 51 males and 45 females aged from 48 to 78 years. All accepted subjects provided the confirmed consent. METHODS： ① Patients in the cerebral infarction group received carotid ultrasound Doppler examination and serum high-sensitivity C-reactive protein detection within 72 hours after onset. IMMAGE immune biochemical system and latex reinforcement particle-enhanced nephelometric ilnmunoassay （PENIA） were used for quantitative detection of serum high-sensitivity C-reactive protein. ② Healthy subjects in the control group received the same detection. SEQUOIA512 color Doppler ultrasound （Siemens Company, USA） was used to detect carotid artery of all subjects so as to observe intima media thickness of artery and formation of artery atherosclerostic plaques. If artery atherosclerostic plaques were formed, their properties and amounts were determined based on the characteristics of light-echo signals. Evaluating criteria： Intima media thickness of artery was the vertical dimension from crossed face between lumen and tunica intima to crossed face between tunica media and tunica adventitia. Intima media thickness ≤ 0.9 into was regarded as normal; 0.9 inm 〈 intima media thickness ≤ 1.2 inm was regarded as thickening; when local eminence thickening was processed towards to lumen, the intima media thickness was more than 1.2 into and plaque of tunica intima was formed at the same time. Properties of plaque were classified into 4 types： steady low-echo lipid malacoplakia, equal-echo fiber plaque, strong-echo or sound-imaging calcification hard plaque and unsteady-echo ulcer mixed plaque. Fiber plaque and calcification hard plaque were steady but malacoplakia and mixed plaque were unsteady. MAIN OUTCOME MEASURES： Thickness of tunica media, characteristics of plaque and level of serum high-sensitivity C-reactive protein in carotid artery in two groups. RESULTS： All 102 patients with cerebral infarction and 96 healthy subjects were involved in the final analysis. ①Comparisons of level of high-sensitivity C-reactive protein： Level of high-sensitivity C-reactive protein in normal tunica media was higher in the cerebral infarction group [（4.66±1.55） mg/L] than the control group [（3.49±1.24） mg/L, t =2.541, P 〈 0.05]. In addition, level of high-sensitivity C-reactive protein in patients with thickening tunica media and plaque was not significantly different between the cerebral infarction group and the control group （P 〉 0.05）. ② Correlation between various degrees of vascular lesion and level of high-sensitivity C-reactive protein in the cerebral infarction group： Level of high-sensitivity C-reactive protein was statistically significantly higher in patients with thickening tunica media [（8.16±2.42） mg/L] than patients with normal tunica media [（4.66±1.55） mg/L, t =4.132, P 〈 0.01]. In addition, level of high-sensitivity C-reactive protein was statistically significantly higher in patients with carotid plaque [（12.08±3.85） mg/L] than patients with normal tunica media （t =5.994, P 〈 0.01） and thickening tunica media （t =4.197, P 〈 0.01）. ③ Levels of high-sensitivity C-reactive protein in patients with various kinds of carotid plaque： Level of high-sensitivity C-reactive protein was statistically significantly higher in patients with unsteady carotid plaque [（13.54±2.62） mg/L] than patients with steady carotid plaque [（8.61±3.71） mg/L, t =2.002, P 〈 0.05]. That was to say level of serum high-sensitivity C-reactive protein in patients who suffered acute cerebral infarction combined with carotid atherosclerosis especially carotid plaque was higher than that in those patients who did not have carotid lesions. This suggested that serum high-sensitivity C-reactive protein had a certain correlation with onset of carotid atherosclerosis in patients with acute cerebral infarction. CONCLUSION： Serum high-sensitivity C-reactive protein certainly correlates with onset of carotid atherosclerosis in patients with acute cerebral infarction, while inflammatory reaction may participate in formation of carotid atherosclerosis in patients with acute cerebral infarction.

Value of N-Terminal Pro B-Type Natriuretic Peptide,High-Sensitivity C-Reactive Protein,and Homocysteine Levels in Predicting Cardiovascular Events in Chronic Heart Failure Patients After Discharge

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.

Association between Metabolic Syndrome Components and Serum High-Sensitivity C-Reactive Protein or Interleukin-6 Levels among Congolese Adults

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.

Correlation between C-reactive Protein and Morphology of Aortic Intramural Hematoma on CT Angiography

Objectives To investigate the morphologic characteristics of intramural hematoma(IMH)on CT angiography(CTA),and evaluate the possible correlation of serum C-reactive protein(CRP)with morphologic characteristics of IMH.Material and Methods Forty-two patients who were initially diagnosed as IMH by aortic CTA and also had serum CRP examination on the same day of CTA were enrolled in this retrospective study,including 30 males and 12 females,with the mean age of 61±14 years old.The volumetric CT data were retrospectively processed and analyzed on post-processing workstation.Based on the thickness of IMH and the length-area curve,the crosssectional area of true lumen and total vessel were measured,the hematoma-vessel ratio(HVR)was calculated.Imaging characteristics were compared between patients who had pathological elevated CRP(>0.8 mg/dl)and those did not.Spearman correlation analyses of CRP level and morphological characteristics of IMH were performed,and the receiver operating characteristic(ROC)curve was used to evaluate the diagnostic validity of CRP.Results Of all 42 IMH patients,the mean serum CRP was 3.94±4.71 mg/dl,and the mean HVR was 46.7%±14.2%.HVR in patients with elevated CRP was significantly higher than those with normal CRP(49.7%±15.0%vs.40.7%±10.5%,P=0.030).HVR was mildly correlated with CRP in all patients(r=0.48,P<0.001).CRP levels differed neither between patients with Stanford type A and B(P=0.207),nor between patients with and without intimal disruption(P=0.230).To discriminate HVR>47%(the mean value),the area under curve(AUC)were 0.700(95%CI:0.535-0.865)for CRP at a cutoff point of 3.55 mg/dl,with a sensitivity of 54.5%and a specificity of 90.0%.Conclusion CRP was mildly correlated with the severity of cross-sectional hematoma area of IMH,but not with Stanford types and the presence of intimal disruption.

Prognostic value of C-reactive protein levels within 6 hours after the onset of acute anterior myocardial infarction with primary PCI

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.

Predictive value of C-reactive protein/albumin ratio in acute pancreatitis

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.

Elevated Homocysteine and C-reactive Protein Levels Independently Predict Worsening Prognosis after Stroke in Chinese Patients

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.
