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.展开更多

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.展开更多

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.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

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.展开更多

From a pathological viewpoint, all stages, ie, initiation, growth, and complication of the atherosclerotic plaque, might be considered to be an inflammatory response to injury. Several prospective studies recently showed that plasma high sensitivity C-reactive protein （hsCRP） levels, which are one of the markers of systemic inflammation, are a powerful predictor of future myocardial infarction and cardiac death among apparently healthy individuals. However, the association between the plasma hsCRP levels and the extent of coronary stenosis in subjects remains controversial. Some studies previously demonstrated such associations, whereas other could not found. Gensini＇s score assigns a severity score for a stenosed vessel depending on the degree of luminal narrowing and the importance of its location.展开更多

文摘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.
文摘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.

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.
文摘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.

文摘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.
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.
文摘Background The association of emerging biomarkers such as high-sensitivity C-reactive protein （hs-CRP）,homocysteine and fibrinogen with the risk of coronary artery disease （CAD） is still uncertain in Asian population including Koreans and little is known about the combined effect of biomarkers on the risk of CAD.Methods A total of 10 650 subjects （6538 men and 4112 women） were enrolled in this study.A 10-year CAD risk was calculated using Framingham risk score modified by the National Cholesterol Education Program （NCEP） Adult Treatment Panel Ⅲ （ATP Ⅲ ） and levels of circulating hs-CRP,homocysteine and fibrinogen were measured using validated assays.Results The 10-year CAD risk gradually augmented with increase in the circulating levels of hs-CRP,homocysteine and fibrinogen.For the highest quartile of hs-CRP,odds ratio （OR） of high-risk for CAD （10-year risk ≥20%） compared with the lowest quartile was 3.97 （95% C/：2.51-6.29）.For homocysteine and fibrinogen,ORs in the highest quartile compared to the lowest quartile were 5.10 （95% Cl：3.05-8.53,P 〈0.001） and 1.46 （95% Cl：0.69-3.11,P=0.325）,respectively.OR of high-risk for CAD in both the highest quartile of hs-CRP and homocysteine was 9.05 （95% CI：5.30-15.45） compared with the below median of hs-CRP and homocysteine.Conclusions The present study demonstrated that hs-CRP and homocysteine are well associated with the 10-year CAD risk estimated using NCEP ATP Ⅲ in Koreans and combination of hs-CRP and homocysteine can have strong synergyin predicting the development of CAD.

文摘A role for inflammation has become well established over the past decade or more in theories describing the atherosclerotic disease process. From a pathological viewpoint, all stages, ie, initiation, growth, and complication of the atherosclerotic plaque, might be considered to be an inflammatory response to injury. Several prospective studies recently showed that plasma high sensitivity C-reactive protein （hsCRP） levels, which are one of the markers of systemic inflammation, are a powerful predictor of future myocardial infarction and cardiac death among apparently healthy individuals. However, the association between the plasma hsCRP levels and the extent of coronary stenosis in subjects remains controversial. Some studies previously demonstrated such associations, whereas other could not found. Gensini＇s score assigns a severity score for a stenosed vessel depending on the degree of luminal narrowing and the importance of its location.
文摘Background：Despite its severity,coronary artery ectasia （CAE） is still poorly understood.High-sensitivity C-reactive protein （hs-CRP） has been recognized as a prognostic factor in some cardiovascular diseases but not assessed in CAE.The aim of this observational study was to investigate the prognostic value of hs-CRP in CAE.Methods：Our analysis evaluated the effect of the baseline hs-CRP on cardiovascular events （CVs） （cardiac death and nonfetal myocardial infarction） in consecutively enrolled stable CAE patients.We used the Cox proportional hazards regression models to examine the association between baseline hs-CRP level and follow-up CVs in CAE.The net reclassification improvement and integrated discrimination improvement （IDI） of hs-CRP were also assessed.Results：We obtained the follow-up results of 540 patients over a median follow-up period of 36 （37.41 ± 15.88） months.The multivariable Cox analysis showed that the hs-CRP was a significant predictor of adverse outcomes in CAE （hazard ratio [HR]：2.99,95% confidence interval [CI]：1.31-6.81,P =0.0091）.In Kaplan-Meier analysis,the group with hs-CRP 〉3 mg/L had a lower cumulative 66-month event-free survival rate （log-rank test for trend,P =0.0235） and a higher risk ofCVs （HR =2.66,95% CI：1.22-5.77,P =0.0140） than the group with hs-CRP ≤3 mg/L.Hs-CRP added predictive information beyond that given by the baseline model comprising the classical risk factors （P value for IDI =0.0330）.Conclusions：A higher level of hs-CRP was independently associated with cardiac death and nonfatal myocardial infarction in CAE patients.The hs-CRP level may therefore provide prognostic information for the risk stratification of CAE patients.
文摘BACKGROUND Gastric cancer is the most common malignancy of the digestive system and surgical resection is the primary treatment.Advances in surgical technology have reduced the risk of complications after radical gastrectomy;however,post-surgical pancreatic fistula remain a serious issue.These fistulas can lead to abdominal infections,anastomotic leakage,increased costs,and pain;thus,early diagnosis and prevention are crucial for a better prognosis.Currently,C-reactive protein(CRP),procalcitonin(PCT),and total bilirubin(TBil)levels are used to predict post-operative infections and anastomotic leakage.However,their predictive value for pancreatic fistula after radical gastrectomy for gastric cancer remains unclear.The present study was conducted to determine their predictive value.AIM To determine the predictive value of CRP,PCT,and TBil levels for pancreatic fistula after gastric cancer surgery.METHODS In total,158 patients who underwent radical gastrectomy for gastric cancer at our hospital between January 2019 and January 2023 were included.The patients were assigned to a pancreatic fistula group or a non-pancreatic fistula group.Multivariate logistic analysis was conducted to assess the factors influencing development of a fistula.Receiver operating characteristic(ROC)curves were used to determine the predictive value of serum CRP,PCT,and TBil levels on day 1 postsurgery.RESULTS On day 1 post-surgery,the CRP,PCT,and TBil levels were significantly higher in the pancreatic fistula group than in the non-pancreatic fistula group(P<0.05).A higher fistula grade was associated with higher levels of the indices.Univariate analysis revealed significant differences in the presence of diabetes,hyperlipidemia,pancreatic injury,splenectomy,and the biomarker levels(P<0.05).Logistic multivariate analysis identified diabetes,hyperlipidemia,pancreatic injury,CRP level,and PCT level as independent risk factors.ROC curves yielded predictive values for CRP,PCT,and TBil levels,with the PCT level having the highest area under the curve(AUC)of 0.80[95%confidence interval(CI):0.72-0.90].Combined indicators improved the predictive value,with an AUC of 0.86(95%CI:0.78-0.93).CONCLUSION Elevated CRP,PCT,and TBil levels predict risk of pancreatic fistula post-gastrectomy for gastric cancer.
文摘Chronic low-grade inflammation is a major contributor to both the onset and advancement of type 2 diabetes mellitus(T2DM),and its associated microvascular complications,including diabetic nephropathy,retinopathy,and peripheral neuropathy.This review aims to overview the roles of high sensitivity C-reactive protein(hs-CRP),C-reactive protein(CRP),CRP-to-lymphocyte count ratio(CLR),and the CRP-to-albumin ratio(CAR)as biomarkers for assessing systemic inflammation and predicting the development and severity of diabetic chronic microvascular complications.Elevated levels of CRP and hs-CRP have been consistently associated with increased risk of these complications,reflecting ongoing inflammatory processes that contribute to endothelial dysfunction and tissue damage.Furthermore,CAR and CLR,which combine CRP with albumin and lymphocyte counts respectively,offer a more nuanced understanding of the inflammatory and immune response in T2DM patients.While individual studies have demonstrated the clinical relevance of these biomarkers in predicting disease onset and progression,further investigation is needed to establish their utility in clinical practice.This review highlights the potential of these biomarkers for enhancing early detection,risk stratification,and personalized management of diabetic patients,ultimately aiming to improve outcomes and reduce the burden of diabetic chronic microvascular complications.

文摘Background:Bacterial pneumonia continues to be a significant global health concern,particularly among high-risk groups,necessitating the development of precise and early diagnostic biomarkers.While the efficacy of procalcitonin(PCT)and C-reactive protein(CRP)as inflammatory markers is widely recognized,their relative diagnostic performance across different age groups remains debate.This meta-analysis was designed to assess the diagnostic accuracy of PCT and CRP in bacterial pneumonia.Methods:In this meta-analysis adhering to PRISMA guidelines,we searched PubMed,Web of Science,and the Cochrane Library for relevant diagnostic accuracy studies.From 19 included studies(n=2,603),data were extracted to construct tables.Study quality was assessed with the QUADAS-2 tool.The bivariate random-effects model was employed to derive pooled sensitivity,specificity,positive and negative likelihood ratios,and summary AUCs.To explore the substantial heterogeneity(I^(2)>80%),we performed pre-specified subgroup analyses based on age demographics.Results:Our findings indicate superior diagnostic performance for PCT,evidenced by a pooled sensitivity of 0.8841 and specificity of 0.8499,relative to CRP’s sensitivity of 0.8371 and specificity of 0.7185.The area under the ROC curve(AUC)for PCT was 0.992,a value significantly higher than that of CRP(0.987).Intriguingly,subgroup analyses revealed age-dependent variations:CRP demonstrated enhanced diagnostic utility in minors,while PCT proved substantially more effective in non-elderly adults.Conclusion:These results reinforce the clinical relevance of PCT as a more dependable biomarker for bacterial pneumonia,particularly in informing antibiotic treatment and mitigating misuse.This study uniquely includes age-stratified analyses based on predefined groups(minors and non-elderly adults),providing refined insights for individualized diagnostic approaches.We propose further multicenter research endeavors to confirm threshold optimization and explore combined biomarker strategies.
