    Chronic inflammation is highly prevalent in patients on hemodialysis (HD), as evidenced by increased levels of C-reactive protein (CRP). We compared CRP to high-sensitivity C-reactive protein (hs-CRP) to determine whether it has any clinical implications and prognostic significance in terms of mortality. CRP was measured using a standard immunoturbidometric assay on the COBAS; INTEGRA system and hs-CRP was measured using the Dade Behring on the Konelab Nephelometer in 50 patients on HD. CRP (...

    Full Text Available Background. Inflammation in the Brugada syndrome (BrS and its clinical implication have been little studied. Aims. To assess the level of inflammation in BrS patients. Methods. All studied BrS patients underwent blood samples drawn for C-reactive protein (CRP levels at admission, prior to any invasive intervention. Patients with a previous ICD placement were controlled to exclude those with a recent (<14 days shock. We divided subjects into symptomatic (syncope or aborted sudden death and asymptomatic groups. In a multivariable analysis, we adjusted for significant variables (age, CRP ≥ 2 mg/L. Results. Fifty-four subjects were studied (mean age 45 ± 13 years, 49 (91% male. Twenty (37% were symptomatic. Baseline characteristics were similar in both groups. Mean CRP level was 1,4 ± 0,9 mg/L in asymptomatic and 2,4 ± 1,4 mg/L in symptomatic groups (P = .003. In the multivariate model, CRP concentrations ≥ 2 mg/L remained an independent marker for being symptomatic (P = .018; 95% CI: 1.3 to 19.3. Conclusion. Inflammation seems to be more active in symptomatic BrS. C-reactive protein concentrations ≥ 2 mg/L might be associated with the previous symptoms in BrS. The value of inflammation as a risk factor of arrhythmic events in BrS needs to be studied.

We compared CRP to high-sensitivity C-reactive protein (hs-CRP to determine whether it has any clinical implications and prognostic significance in terms of mortality. CRP was measured using a standard immunoturbidometric assay on the COBAS; INTEGRA system and hs-CRP was measured using the Dade Behring on the Konelab Nephelometer in 50 patients on HD. CRP (≥6 mg/L and hs-CRP (≥3 mg/L levels were elevated in 30% and 54% of the patients, respectively. A significant correlation was noted between hs-CRP and CRP levels (r = 0.98, P <0.001. Deming regression analysis showed that the slope was near one (r = 0.90; 0.83-0.94 and that the intercept was small. Multivariate regression confirmed that age above 40 years (RR = 3.69, P = 0.027 and duration on HD greater than five years (RR = 3.71, P = 0.028 remained significant independent predictors of serum hs-CRP. Thirteen patients died during follow-up (26%. Multivariate Cox regression demonstrated that hs-CRP (RR = 1.062, P = 0.03 and CRP levels (RR = 1.057, P = 0.009 and age (RR = 1.078, P = 0.001 were the most powerful predictors of mortality. The CRP standard assay presents a reasonable alternative to the hs-CRP assay in patients on HD. The advantages of the CRP standard assay are its online and real-time availability as well as lower costs, particularly in developing countries.

    Full Text Available In unstable angina (USA patients, immunological responses contributing to inflammation play a vital role in plaque rupture and thrombosis causing stroke. In the present study an attempt is made to estimate the levels of adenosine deaminase activity, an immunoenzyme marker and C-reactive protein, a marker of inflammation in USA patients. 45 patients presenting USA and 50 age and sex matched healthy controls were included in the study. Serum ADA activity was measured spectrophotometrically at 630nm and serum C-reactive protein was detected using Avitex CRP kit, which is a rapid latex agglutination test. The Mean ADA levels were 41.15 ± 11.04 in patients and 20.71±5.63 in controls and 66.6% of patients and none of the controls were positive to CRP. The present study observed the importance of ADA as a serum marker in addition to CRP for assessing the immune response in USA patients.

    Full Text Available Background: Elevation of C-reactive protein (CRP has been reported to occur in psoriasis, urticaria, acne, rosacea and many other dermatological and nondermatological conditions. Chronic systemic inflammation has been implicated in the development of neuropsychiatric/degenerative disorders, atherosclerosis, coronary artery disease, diabetes mellitus and even carcinogenesis. The present study is designed to determine whether the level of inflammation created by acne vulgaris could be high enough to raise the serum levels of high-sensitive CRP. Materials and Methods: Forty-two patients with moderate and severe acne vulgaris were enrolled, along with 44 age and sex matched healthy blood donors as controls. Hypersensitive-CRP (Hs-CRP was measured in both groups. Results: Hypersensitive-C-reactive protein levels in the case group varied between 0 and 28.1 μg/ml with an average of 2.24 ± 4.87 μg/ml (mean ± standard deviation and a median of 0.6 μg/ml (interquartile range [IQR] =0.3, 1.4 μg/ml. Hs-CRP levels of the control group varied between 0 and 14 μg/ml with an average of 3.12 ± 3.67 μg/ml and a median of 1.5 μg/ml (IQR = 0.55, 5.0 μg/ml. No significant difference of Hs-CRP level between the two groups was seen (t = -0.961, 95% confidence interval: Lower = -2.6942, upper = 0.9377; P = 0.339. Additionally, no significant difference in the level of Hs-CRP was noted between the moderate and severe acne groups (95% confidence interval: Lower = -5.2495, upper = 1.6711; P = 0.165. Conclusion: Acne vulgaris, even in its severe grades (excluding acne fulminans and acne conglobata, does not induce significant inflammation at the systemic level.

Several prospective studies 5-7 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 demon- strated such associations,8,9 whereas other could not found.10,11 Gensini's score assigns a severity score for a stenosed vessel depending on the degree of luminal narrowing and the importance of its location.12

    Full Text Available Introduction:There is a growing body of data concerning significant interactions between markers of inflammation and cardiovascular diseases such as hypertension accompanied by elevated levels of plasma C-reactive protein (CRP. Therefore CRP is thought to be an independent risk factor of cardiovascular diseases.Material/Methods:The aim of this study was to evaluate the effects of antihypertensive therapy (perindopril, bisoprolol and combined therapy on plasma CRP concentration in 67 subjects with mild or moderate hypertension who have been treatment-naive and otherwise healthy.Results:The results show a correlation between CRP level and blood pressure values. BP reduction was associated with a decrease in CRP concentration. The CRP-lowering effect of perindopril and bisoprolol was comparable and the degree of reduction might reflect their similar influence on blood pressure. Combined treatment influenced the CRP level to a greater extent than both monotherapies.Conclusions:Plasma CRP level was lowered by antihypertensive therapy independently of the drug applied. The CRP level did not normalize completely in moderate hypertensive patients.

    International Nuclear Information System (INIS)

    The objective of this study was to evaluate cardiorespiratory fitness and pulmonary function and the relationship with metabolic variables and C-reactive protein (CRP) plasma levels in individuals with diabetes mellitus (DM). Nineteen men with diabetes and 19 age- and gender-matched control subjects were studied. All individuals were given incremental cardiopulmonary exercise and pulmonary function tests. In the exercise test, maximal workload (158.3±22.3 vs 135.1±25.2, P=0.005), peak heart rate (HRpeak: 149±12 vs 139±10, P=0.009), peak oxygen uptake (VO2peak: 24.2±3.2 vs 18.9±2.8, P<0.001), and anaerobic threshold (VO2VT: 14.1±3.4 vs 12.2±2.2, P=0.04) were significantly lower in individuals with diabetes than in control subjects. Pulmonary function test parameters, blood pressure, lipid profile (triglycerides, HDL, LDL, and total cholesterol), and CRP plasma levels were not different in control subjects and individuals with DM. No correlations were observed between hemoglobin A1C (HbA1c), CRP and pulmonary function test and cardiopulmonary exercise test performance. In conclusion, the results demonstrate that nonsmoking individuals with DM have decreased cardiorespiratory fitness that is not correlated with resting pulmonary function parameters, HbA1c, and CRP plasma levels

    Richard Schwameis

    Full Text Available C-reactive protein (CRP has previously been shown to serve as a prognostic parameter in women with gynecologic malignancies. Due to the lack of valid prognostic markers for uterine leiomyosarcoma (ULMS this study set out to investigate the value of pre-treatment CRP serum levels as prognostic parameter.Data of women with ULMS were extracted from databases of three Austrian centres for gynaecologic oncology. Pre-treatment CRP serum levels were measured and correlated with clinico-pathological parameters. Univariate and multivariable survival analyses were performed.In total, 53 patients with ULMS were included into the analysis. Mean (SD CRP serum level was 3.46 mg/dL (3.96. Solely, an association between pre-treatment CRP serum levels and tumor size (p = 0.04 but no other clinic-pathologic parameter such as tumor stage (p = 0.16, or histological grade (p = 0.07, was observed. Univariate and multivariable survival analyses revealed that CRP serum levels (HR 2.7 [1.1-7.2], p = 0.037 and tumor stage (HR 6.1 [1.9-19.5], p = 0.002 were the only independent prognostic factors for overall survival (OS in patients with ULMS. Patients with high pre-treatment CRP serum levels showed impaired OS compared to women with low levels (5-year-OS rates: 22.6% and 52.3%, p = 0.007.High pre-treatment CRP serum levels were independently associated with impaired prognosis in women with ULMS and might serve as a prognostic parameter in these patients.

    Full Text Available Objectives. To compare the value of procalcitonin, C-reactive protein (CRP and neopterin as indicators of immune deficiency, co-infection, efficacy of treatment, and disease progression, in patients with advanced HIV-1 infection. Design. Cross-sectional, investigating baseline blood measurements and clinical observations in 82 HIV-positive patients divided into an antiretroviral treatment (ART group and an ART-naïve group. Setting. Secondary general hospital in Pretoria. Results. Procalcitonin and CRP levels showed no significant differences between the ART and ART-naïve groups, and no correlations with CD4 counts or viral loads. CRP levels were significantly higher with TB co-infection (p<0.05. Neopterin levels were raised above normal in 92% of the ART-naïve group and in 75% of the ART group. The levels were significantly higher (p<0.05 in the ART- naïve group. Negative correlations were found between neopterin and CD4 counts for the total patient group (r=-0.482; p<0.001. Neopterin was significantly (p<0.05 higher in the HIV/TB co-infection group than in those without TB. Higher neopterin levels at baseline were associated with a decline in CD4 counts over the ensuing 6-month period, and patients with higher baseline neopterin levels developed more complications over the 6-month period. Conclusions. Compared with procalcitonin and CRP, neopterin appears to be associated with the degree of immunodeficiency and of co-infection with TB. Neopterin levels may be investigated further as a measure of disease progression or treatment response. S Afr J HIV Med 2012;13(2:78-82.

  14. PLASMA C-REACTIVE PROTEIN LEVELS AS A PROGNOSTIC MARKER IN FIRST EVER ACUTE ISCHEMIC STROKE

    2014-12-01

    Full Text Available BACKGROUND AND PURPOSE: Acute ischemic stroke may trigger an inflammatory response that leads to increased levels of C-reactive protein (CRP. High levels of CRP may be associated with poor outcome because they reflect either an inflammatory reaction or tissue damage. We related plasma CRP levels to first ever ischemic stroke and its role as a diagnostic aid. METHODS: Sixty patients fulfilling inclusion and exclusion criteria with first ever acute ischemic stroke were included in study. CT scan of brain was done after 24 hours of onset of symptoms to confirm the diagnosis. Plasma CRP level was determined after 12 hours and before 72 hours of onset of symptoms in all CT confirmed ischemic stroke patients. This clinical study was done from January 2008 to June 2009. CRP was randomly measured in 60 age and sex matched individuals admitted in other wards of the hospital matched in all possible criteria expect the disease under study as a control group. RESULTS: The CRP concentration in ischemic strokes was independent of infarction site, the value was more between 51-70 years of age group and almost equal in both genders. 54 of the 60 ischemic strokes studied had CRP value >6 mg/l and only 6 patients had 6 mg/l, which is insignificant. CONCLUSION: The CRP level is significantly higher in ischemic strokes and by its elevation between 12-72 hours of symptom onset is a bad prognostic indicator. The risk of poor outcome or death at 3 months increased with higher levels of CRP. Elevated CRP values is a risk factor in association with other risk factors like diabetes/hypertension

    Full Text Available Abstract Background While low-grade inflammation has consistently been observed in subjects with depression, studies on the possible relationship between inflammation and other aspects of brain function are as yet sparse. In this study, we aimed to investigate the possible association between serum levels of the inflammation marker C-reactive protein (CRP and personality traits. Methods In this study, serum levels of high-sensitivity CRP were determined by ELISA in a population of 270 42-year-old women recruited from the population registry who had been assessed using the Temperament and Character Inventory. Self-reported previous or ongoing depression was also recorded. Unpaired two-tailed t-tests were used for comparison between two groups and correlations were evaluated by the calculation of Pearson's r-coefficient. Results The temperament trait harm avoidance was positively (r = 0.227, p r = -0.261, p p-values corrected for multiple comparisons. The correlations between the personality traits and CRP were observed also after exclusion of subjects reporting ongoing depression (n = 26. Whereas women reporting ongoing depression showed significantly increased levels of CRP as compared to non-depressed women (n = 155, women reporting a history of depression displayed no significant difference in CRP levels as compared to women that reported that they had never been depressed. Conclusion Serum levels of CRP in women was found to be associated with the personality traits harm avoidance and self-directedness. In addition, moderately elevated levels may be a state dependent marker of depression.

    Full Text Available Abstract Background Chronic kidney disease (CKD is a newly recognized high-risk condition for cardiovascular disease (CVD, and previous studies reported the changes in inflammation and oxidative stress in advanced stages of CKD. We compared the levels of serum biomarkers for inflammation and oxidative stress between subjects with normal and mildly reduced glomerular filtration rate (GFR. Methods The subjects were 182 participants of a health check-up program including those with normal (≥ 90 mL/min/1.73 m2, N = 79 and mildly reduced eGFR (60-89 mL/min/1.73 m2, N = 103 which was calculated based on serum creatinine, age and sex. We excluded those with reduced eGFR 2. No one had proteinuria. We measured serum levels of C-reactive protein (CRP and thioredoxin (TRX as the markers of inflammation and oxidative stress, respectively. Results As compared with subjects with normal eGFR, those with mildly reduced eGFR had increased levels of both CRP and TRX. Also, eGFR was inversely correlated with these biomarkers. The associations of eGFR with these biomarkers remained significant after adjustment for age and sex. When adjustment was done for eight possible confounders, CRP showed significant association with systolic blood pressure, high density lipoprotein cholesterol (HDL-C and non-HDL-C, whereas TRX was associated with sex significantly, and with eGFR and systolic blood pressure at borderline significance. Conclusions We showed the increased levels of CRP and TRX in subjects with mildly reduced eGFR. The eGFR-CRP link and the eGFR-TRX link appeared to be mediated, at least partly, by the alterations in blood pressure and plasma lipids in these subjects.

    Based on the existing evidence supporting a state of chronic inflammation in chronic kidney disease (CKD), we hypothesized that periodontal infection may affect the systemic inflammatory status of a nationally representative CKD population as measured by serum C-reactive protein (CRP). We examined this hypothesis using the National Health and Nutrition Examination Survey 1988-1994 (NHANES III) dataset including 2303 individuals. We followed the American Academy of Periodontology (AAP)/Centers for Disease Control and Prevention (CDC) case definition for periodontitis. We used a cutoff point of 30% sites with (PD) ≥ 5 mm and (CAL) ≥ 4 mm to define generalized periodontitis cases. We estimated glomerular filtration rate based on cystatin C levels using the relevant equation. Urinary albumin-to-creatinine ratio was calculated in milligrams per gram with a cutoff point of 30 mg/g. CKD was defined based on eGFR < 60 mL/min/1.73 m(2) and albuminuria ≥ 30 mg/g. Periodontitis was found in 427 (12.3%) individuals. Of individuals with periodontitis, 41.8% had serum CRP higher than 0.3 mg/dL compared with 27.1% of non-periodontitis and 53.1% of edentulous individuals (p = 0.001 for all comparisons). When the extent of periodontitis was used as one of the independent variables, the parsimonious model showed a strong independent association between extent of periodontitis and serum CRP levels (OR = 2.0, CI95% = 1.2-3.6).

    Although many studies have found psychological depression associated with higher circulating levels of C-reactive protein (CRP), not all findings are consistent. Since DNA sequence variation in the CRP gene has also been shown to predict plasma CRP levels, we hypothesized that plasma CRP may covary with depressive symptomatology as a function of allelic variation in the CRP gene. We tested this hypothesis in 868 healthy community volunteers of European ancestry. Depressive symptomatology was ...

  3. An Evaluation of Serum Procalcitonin and C-Reactive Protein Levels as Diagnostic and Prognostic Biomarkers of Severe Sepsis

    Directory of Open Access Journals (Sweden)

    Szederjesi Janos

    2015-10-01

    Full Text Available Background: Recommendations have been made, following the multicenter Surviving Sepsis Campaign study, to standardize the definition of severe sepsis with reference to several parameters such as haemodynamic stability, acid-base balance, bilirubin, creatinine, International Normalized Ratio (INR, urine output and pulmonary functional value of the ratio between arterial oxigen partial pressure and inspiratory oxigen concentration. Procalcitonin (PCT is considered to be a gold standard biomarker for the inflammatory response, and recent studies have shown that it may help to discover whether a seriously ill person is developing sepsis. C-reactive protein (CRP is also used as a marker of inflammation in the body, as its blood levels increase if there is any inflammation in the body. The aim of this study was to evaluate serum procalcitonin and C-reactive protein levels as diagnostic and prognostic biomarkers of severe sepsis.

    Full Text Available Objective. Despite considerable study, the relevance of leptin and adiponectin for atherosclerosis development is still unsettled. We investigated relations of serum leptin and adiponectin to serum C-reactive protein (CRP, using the INTERLIPID dataset on Japanese emigrants living in Hawaii and Japanese in Japan. Design and Methods. Serum leptin, adiponectin, and CRP were measured by standardized methods in men and women of ages 40 to 59 years from two population samples, one Japanese-American in Hawaii (83 men, 89 women and the other Japanese in central Japan (111 men, 104 women. Participants with CRP >10 mg/L were excluded. Results. Sex-specific multiple linear regression analyses, with log-transformed leptin and adiponectin (log-leptin, log-adipo, site (Hawaii = 1, Japan = 0, SBP, HbA1c, smoking (cigarettes/day, and physical activity index score of the Framingham Offspring Study as covariates, showed that log-leptin directly related and log-adipo inversely related to log-CRP for both sexes (Ps < 0.05 to <0.01. Addition to the model of BMI and interaction terms (BMI × log-leptin, BMI × log-adipo, SITE × log-leptin, SITE × log-adipo resulted in disappearance of statistical significance except for direct relation of log-leptin to log-CRP in men (P=0.006. Conclusions. Leptin directly related to CRP independent of BMI and other confounding factors in men but not in women.

    Background Gastritis is an important premalignant lesion and recent studies suggested a production of inflammatory cytokine-like C-reactive protein during gastritis. This study aimed to determine any relationship between high sensitive C-reactive protein (hs-CRP) and inflammation activity among patients with gastritis. Methods Demographic and clinical variables of participants were collected by a validated questionnaire. Using histology of the gastric mucosa, Helicobacter pylori status was investigated and serum concentrations of hs-CRP were measured among dyspeptic patients. Correlation between hs-CRP serum levels and inflammation activities was evaluated by logistic regression analysis. The relation between active inflammation and other variables was evaluated by logic link function model. Results Totally 239 patients (56.6% female) were analysed. The prevalence of mild, moderate and severe inflammation activities was 66.5%, 23.8% and 9.6% respectively. Mean ± SD of hs-CRP among men and women were 2.85 ± 2.84 mg/dl and 2.80 ± 4.80 mg/dl (p = 0.047) respectively. Mean ± SD of hs-CRP among patients with H. pylori infection, gland atrophy, metaplasia and dysplasia were 2.83 ± 3.80 mg/dl, 3.52 ± 5.1 mg/dl, 2.22 ± 2.3 mg/dl and 5.3 ± 5.04 mg/dl respectively. Relationship between hs-CRP and inflammation activities (p gastritis, elevated hs-CRP levels may be considered as a predictive marker of changes in gastric mucosa and a promising therapeutic target for patients with gastritis.

  13. Level of high-sensitivity C-reactive protein in saudi patients with chronic stable coronary artery disease

    International Nuclear Information System (INIS)

    Inflammatory biomarker high-sensitivity C-reactive protein (hsCRP) is an independent predictor of future cardiovascular events and it predicts risk of incident hypertension and diabetes. The aim of this study was to determine the serum levels of the circulating acute-phase reactant high-sensitivity C-reactive protein (hsCRP) in Saudi patients with chronic stable Coronary Artery Disease (CAD). This cross sectional study was conducted in the Department of Physiology and Department of Cardiology, College of Medicine and King Khalid University Hospital, King Saud University, Riyadh between August 2006 and December 2007. One hundred and seven individuals with chronic stable CAD and 33 healthy, age and BMI-matched individuals were studied. Overnight fasting blood samples were collected, and analyzed for total cholesterol (TC), Triglycerides (TG), Low Density Lipoprotein (LDL) and High Density Lipoprotein (HDL) and hsCRP in patients with chronic stable CAD. TC (Control 4.41+-0.57 vs CAD 4.28+-1.40, p=0.8394) and LDL levels (Control 2.70+-0.52 vs CAD 2.71+-1.20, p=0.7963) did not differ significantly between the two groups. While there were significant differences in TG (Control 1.13+-0.47 vs CAD 1.84+-1.10, p=0.0135) and HDL levels (Control 1.06+-0.30 vs CAD 0.71+-0.25, p=0.0000). hsCRP levels were significantly higher in patients with CAD (5.0+-4.4) compared to healthy individuals (2.7+-2.7, p=0.0166). Frequency of low risk levels was significantly higher in Controls than CAD patients (24.2% vs 8.4%, p=0.0332) and vice versa for high risk levels (24.2% vs 51.4%, p=0.0110). At average risk levels frequency did not differ significantly (51.5% vs 40.1%, p=0.3429) between control and CAD groups. Saudi patients with stable chronic CAD have higher hsCRP levels compared to healthy individuals. Moreover the prevalence of undesirable risk levels of hsCRP is also higher in CAD patients. (author)

    Many observational studies have shown elevated blood CRP levels in schizophrenia compared with controls, and one population-based prospective study has reported that elevated plasma CRP levels were associated with late- and very-late-onset schizophrenia. Furthermore, several clinical studies have reported the efficacy of anti-inflammatory drugs on the symptoms in patients with schizophrenia. However, whether elevated CRP levels are causally related to schizophrenia is not still established because of confounding factors and reverse causality. In the present study, we demonstrated that serum CRP levels were significantly higher in patients with schizophrenia than in the controls by conducting a case-control study and a meta-analysis of case-control studies between schizophrenia and serum CRP levels. Furthermore, we provided evidence for a causal association between elevated CRP levels and increased schizophrenia risk by conducting a Mendelian randomization analysis. Our findings suggest that elevated CRP itself may be a causal risk factor for schizophrenia. PMID:27193331

  15. Study on plasma C-reactive protein and IL-6 levels in patients with acute coronary syndrome

    International Nuclear Information System (INIS)

    Objective: To explore the difference between the plasma C-reactive protein (CRP) and serum interleukin 6(IL-6) levels of patients with acute coronary syndrome (ACS) and patients with stable angina pectoris (SAP). Methods: Plasma CRP (with immunoturbidometry) and serum IL-6 (with RIA) levels were determined in the following subjects: 1) 57 patients with ACS including 21 with acute myocardial infarction (AMI) and 36 with unstable angina pectoris (UAP; Braunwald grade I 11, grade II 10, grade III 15), 2) 48 patients with stable angina pectoris (SAP) as controls. Results: Plasma levels of CRP and serum level IL-6 in patients with AMI and patients with UAP were significantly higher than those in the controls (P0.05). Plasma CRP levels were correlated positively to IL-6 in all these three groups (rAMI=0.569, rUAP=0.413, rSAP=0.475, P<0.01, P<0.05). Conclusion: Plasma levels of CRP and IL-6 were higher in patients with ACS, indicating the important role played by inflammation in the pathogenesis. (authors)

    Full Text Available Background: Cardiovascular disease is the most common cause of death in the world. The aim of this study was to determine the effect of aerobic exercise on serum inflammatory markers in untrained middle-aged women. Methods: Nineteen healthy female middle-aged were selected by convenience sampling method and were randomly divided into two experimental (n=11 and control (n=8 groups. The exercise protocol included aerobic exercise training lasted for 6 months and 3 sessions per week and every session lasted for 60 minutes and with intensity of 55-65 percent of maximum heart rate reserve (MHR. Blood samples were taken to measure serum leptin and C-Reactive Protein (CRP before and after aerobic training period. General linear- Repeated measures (GL-RM was used to comparing of within, Interactive and between means groups. The level of significance was set at P< 0.05. Results: The level of serum leptin in middle-aged women did not change significant. However, the levels of CRP during this period did not change significantly. Conclusion: Six months of aerobic exercise does not induce significant change in serum levels of CRP, while leptin levels reduced in middle-aged women. Regular physical activity probably causes decrease in serum leptin level if body mass index and body fat mass reduce simultaneously.

  17. Correlation of insulin resistance with serum C-reactive protein, adiponectin and leptin levels in patients with type 2 diabetes

    International Nuclear Information System (INIS)

    Objective: To explore the relationship between serum C-reactive protein (CRP), adiponectin (APN), leptin (Leptin) levels, insulin resistance index (HOMA-IR) and type 2 diabetes mellitus (T2DM) disease susceptibility. Methods: The plasma leptin and insulin (FINS) levels in the DM patients were determined by RIA, and the serum ANP levels were determined by ELSIA. The CRP, conventional serum fasting plasma glucose (FPG) levels were determine by automatic biochemistry analyzer. The insulin resistance index (HOMA-IR, FPG x FINS/22.5) was calculated. The result was analyzed with normal healthy control group. Results: The serum CRP and leptin, HOMA-IR levels in T2DM group were significantly higher than that of in control group (P< 0.01), and the serum ANP was significantly lower than in control group (P<0.01). The HOMA-IR in T2DM was positively correlated with serum CRP (r= 0.36, P<0.05) and leptin(r= 0.39, P<0.05), and was negatively correlated with serum APN (r=0.32, P<0.05). Conclusion: The high serum CRP and leptin and low APN levels hyperlipidaemia might be factors for diabetes, and their metabolic disorders may be closely related with insulin resistance in patients with type 2 diabetes.

Patients were divided into three risk groups according to hs-CRP levels (3mg/L- as high risk). Mean Angiographic Gensini scores were compared among the risk groups. Correlation between serum hs-CRP levels and angiographic Gensini scores was also assessed. Results: The 26 (32.5%) patients belonging to hs-CRP low-risk group had a mean angiographic Gensini score of 11.8 +- 5.8, 18 (22.5%) belonging to moderate-risk group had a mean score of 28.9 +- 7.9 and 36 (45%) belonging to high- risk group had a mean score of 78.7 +- 41.0. By applying ANOVA the mean angiographic Gensini scores showed increasing trend from lower to higher hs-CRP risk groups (p < 0.001). Serum hs-CRP levels showed significant correlation with respective angiographic Gensini scores by Pearson's correlation (p < 0.001). Conclusion: Serum hs-CRP levels show significant correlation with the severity of Coronary Artery Disease as assessed by angiographic Gensini score. (author)

    Full Text Available Inflammation and cardiovascular disease are associated with elevated serum levels of C-Reactive Protein (CRP and homocysteine. The presence of both molecules in saliva provides an opportunity for development of non-invasive assessments of disease risk. However, salivary CRP and homocysteine reference ranges and their correlation with serum levels are unknown. This study investigated if CRP and homocysteine could be routinely detected in the saliva of healthy adults and the relationship between salivary and blood levels. CRP and homocysteine concentrations were determined using ELISA and enzymatic assays respectively. Homocysteine was detected in only two saliva samples (n = 55. CRP was measurable in all saliva samples (range: 0.05 to 64.3 µg/L; median = 1.2 µg/L and plasma samples (range: 0.14 to 31.1 mg/L; median = 2.0 mg/L. Regression analysis demonstrated no relation- ship between CRP concentration in saliva and plasma (R2 = 0.001. Generalized linear models including variables such as saliva flow rate and time since eating or drinking also did not pass lack of fit testing. Therefore, a relationship between CRP concentration in saliva and blood could not be established in this group of subjects. More sensitive detection methods are needed to determine if a correlation between salivary and serum homocysteine levels exists.

  20. Clinical significances of preoperative serum interleukin-6 and C-reactive protein level in operable gastric cancer

    International Nuclear Information System (INIS)

    The interleukin-6 (IL-6) pathway is one of the mechanisms that link inflammation and angiogenesis to malignancy. Because the C-reactive protein (CRP) is a representative marker for inflammation, CRP has recently been associated with the progression of disease in many cancer types. The principal objective of this study was to determine the preoperative serum levels of IL-6 and CRP in gastric carcinoma, and to correlate them with disease status and prognosis. A total of 115 patients who underwent gastrectomy were enrolled in this study. Serum levels of IL-6 were assessed via Enzyme-Linked Immuno-Sorbent Assay (ELISA), and CRP was measured via immunoturbidimetry. Histological findings included tumor size, depth of tumor invasion, lymph node (LN) metastasis, and TNM stage (6th AJCC Stage Groupings: The staging systems; Primary tumor, regional LN, metastasis). Increases in cancer invasion and staging are generally associated with increases in preoperative serum IL-6 levels. IL-6 and CRP levels were correlated with invasion depth (P < 0.001, P = 0.001), LN metastasis (P < 0.001, P = 0.024) and TNM stage (P < 0.001, P < 0.001). The presence of peritoneal seeding metastasis is associated with IL-6 levels (P = 0.012). When we established the cutoff value for IL-6 level (6.77 pg/dL) by ROC curve, we noted significant differences in time to progression (TTP; P < 0.001) and overall survival (OS; P = 0.010). However, CRP evidenced no significance with regard to patients' TTP and OS levels. Serum IL-6 levels were correlated positively with CRP levels (r2 = 0.049, P = 0.018). Preoperative serum IL-6 and CRP levels might be markers of tumor invasion, LN metastasis, and TNM stage. Preoperative high IL-6 levels were proposed as a poor prognostic factor for disease recurrence and overall survival in patients with gastric cancers

    This is a large cohort analysis in severely burned pediatric children to determine whether C-reactive protein (CRP) can be used as a predictor for severe infection or sepsis. Nine-hundred eighteen pediatric burn patients were enrolled in this study. CRP values were measured throughout acute hospitalization and for up to 6 months postburn. Demographic data, incidence of infection, surgical interventions and other relevant clinical information was compiled from medical records. We performed an extensive literature search to identify models that other groups have developed to determine the effects of CRP levels postburn to assess the value of these parameters as predictors of sepsis or severe infection. Statistical analysis was performed using ANOVA and regression analysis where appropriate. Three-hundred fifteen female and 603 male pediatric patients were enrolled in this study. Average total body surface area (TBSA) burn was 45±23%, with full thickness burn over 32±27% TBSA, and patients were 7±6 years old. CRP values significantly correlated with burn size, survival and gender. Significantly higher levels of CRP were found in large burns, in non-survivors, and in females, p<0.05. Using various described models to determine whether CRP levels change before and after an event can predict sepsis or severe infection, we found that CRP cannot predict severe infection or sepsis. Although CRP is a marker of the inflammatory response postburn, CRP fails to predict infection or sepsis in severely burn patients. PMID:23875119

    Full Text Available Abstract Background We examined salivary C-reactive protein (CRP levels in the context of tobacco smoke exposure (TSE in healthy youth. We hypothesized that there would be a dose-response relationship between TSE status and salivary CRP levels. Methods This work is a pilot study (N = 45 for a larger investigation in which we aim to validate salivary CRP against serum CRP, the gold standard measurement of low-grade inflammation. Participants were healthy youth with no self-reported periodontal disease, no objectively measured obesity/adiposity, and no clinical depression, based on the Beck Depression Inventory (BDI-II. We assessed tobacco smoking and confirmed smoking status (non-smoking, passive smoking, and active smoking with salivary cotinine measurement. We measured salivary CRP by the ELISA method. We controlled for several potential confounders. Results We found evidence for the existence of a dose-response relationship between the TSE status and salivary CRP levels. Conclusions Our preliminary findings indicate that salivary CRP seems to have a similar relation to TSE as its widely used serum (systemic inflammatory biomarker counterpart.

    Background Obstructive sleep apnea syndrome (OSAS), characterized by intermittent hypoxia/reoxygenation (IHR),has been identified as an independent risk factor for cardiovascular diseases (CVD). The CVD biomarkers associated with OSAS have not been thoroughly investigated.Methods Fifty-one men with OSAS recently diagnosed by polysomnography were classified into two groups according to the severity of apnea: moderate to severe OSAS group (n= 28) and mild OSAS group (n= 23). Twenty-five obese men,of comparable age and body mass index (BMI), without OSAS were chosen as control subjects. Serum metabolic variables, C-reactive protein (CRP) and matrix metalloproteinase-9 (MMP-9) were measured. Spearman correlation and regression analysis were performed.Results Serum concentrations of CRP and MMP-9 were significantly higher in 51 OSAS patients than in 25 control subjects. Levels of CRP and MMP-9 were significantly higher in patients with moderate to severe OSAS than in patients with mild OSAS or in obese control subjects. A positive correlation was found between levels of CRP and MMP-9 in OSAS patients. Regression analysis showed that after adjusting for age and BMI, apnea/hypopnea index (AHI) significantly correlated with serum concentrations of CRP and MMP-9 in patients with OSAS.Conclusions AHI, mirroring the frequency of IHR, was a predictor of enhanced circulating CVD biomarkers MMP-9 and CRP. Our data support the theory that IHR contributes to the upregulation of the inflammatory factors in OSAS patients.

  8. Can perioperative C-reactive protein and interleukin-6 levels predict atrial fibrillation after coronary artery bypass surgery?

    International Nuclear Information System (INIS)

    Objective was to examine the relationship between proinflammatory cytokines such as interleukin-6 (IL-6) and C-reactive protein (CRP) and atrial fibrillation and after on-pump coronary artery bypass grafting (CABG). Fifty-four patients with coronary artery disease undergoing elective CABG at the Mazandaran Medical University, Mazandaran, Iran were enrolled in our prospective study in the year 2007. Postoperatively, heart rate and rhythm were continuously monitored for 5 days. Fasting blood samples were taken from all patients to examine quantities of CRP and IL-6 the day before surgery and on the second postoperative day in the intensive care unit. From 54 patients, 11 patients (20.4%) developed atrial fibrillation (AF) after CABG. The median age of patients with AF was 51.45+/-10.74 compared with 57.28+/-9.04 for patients with sinus rhythm (p=0.072). Cardioplegic time, cross clamp time and pump time were higher in the AF group but there was no significant difference between the 2 groups. Preoperative CRP and IL-6 levels were higher in patients with AF. The CRP and IL-6 increased after CABG in all patients but it increased more in the AF group. There was a significant relationship between preoperative IL-6 and AF in patients who underwent on-pump CABG, but there was no relationship between CRP and AF. Therefore, administration of glucocordicoids which significantly reduce plasma levels of IL-6 can reduce the incidence of AF after on-pump CABG. (author)

    2010-01-01

    Full Text Available Background: C-reactive protein [CRP] levels increase to hundreds of mg/mL within hours following infection. Studies have shown that serum CRP levels were elevated in periodontal disease. However, in all the previous studies, CRP levels were measured by using high-sensitivity CRP assay kits with minimal detection limits of 0.1 to 3 mg/L, which was much below the normal value of 10 mg/L. These high-sensitivity CRP assays need a proper laboratory setup, and these methods cannot be used as a routine chair-side test in the dental office. Aim: The purpose of this study was to investigate the serum CRP levels in subjects with periodontal disease by using a rapid chair-side diagnostic test kit with a lower detection limit of 6 mg/L and to compare the CRP levels before and after periodontal therapy. Materials and Methods: A total of 45 systemically healthy subjects were selected for the study. Subjects were divided into three groups: group A: healthy controls, group B: gingivitis, group C: periodontitis. Serum levels of CRP were determined by using a latex slide agglutination method with commercially available kit with lower detection limit of 6 mg/L. Results: CRP was negative in all the 15 subjects in groups A and B at baseline, 7th and 30th day. CRP was positive only in 2 subjects in Group C at baseline and 7th day. Conclusion: Estimation of serum CRP by using a rapid chair-side diagnostic test kit is not of any significance in subjects with periodontitis.

    Objective The occurrence of acute cerebral infection following deep brain stimulation (DBS) is currently being reported with elevation of C-reactive protein (CRP) level. The aim of the present study was to establish normal range of the magnitude and time-course of CRP increases following routine DBS procedures in the absence of clinical and laboratory signs of infection. Methods A retrospective evaluation of serial changes of plasma CRP levels in 46 patients undergoing bilateral, two-staged DBS was performed. Because DBS was performed as a two-staged procedure involving; implantation of lead and internal pulse generator (IPG), CRP was measured preoperatively and postoperatively every 2 days until normalization of CRP (post-lead implantation day 2 and 4, post-IPG implantation day 2, 4, and 6). Results Compared with preoperative CRP levels (0.12±0.17 mg/dL, n=46), mean CRP levels were significantly elevated after lead insertion day 2 and 4 (1.68±1.83 mg/dL, n=46 and 0.76±0.38 mg/dL, n=16, respectively, p0.05). Mean CRP levels after IPG implantation were significantly higher in patients whose IPGs were implanted at post-lead day 3 than those at post-lead day 5-6 (3.99±2.80 mg/dL, n=30, and 2.31±1.56 mg/dL, n=16, respectively, p0.05). Conclusion The mean postoperative CRP levels were highest on post-IPG insertion day 2 and decreased rapidly, returning to the normal range on post-IPG implantation day 6. The duration of post-lead implantation period influenced the magnitude of CRP elevation at post-IPG insertion day 2. Information about the normal response of CRP following DBS could help to avoid unnecessary diagnostic and therapeutic efforts. PMID:26587192

    AIM:To explore if C-reactive protein (CRP) levels might serve as a prognostic factor with respect to the clinical course of Crohn's disease and might be useful for classification. METHODS: In this retrospective cohort study we enrolled 94 patients from the inflammatory bowel disease (IBD) database of the University Medical Centre Utrecht. CRP levels during relapse were correlated with the number of relapses per year. Severity of relapses was based on endoscopic reports and prednisone use. Furthermore, patients were categorized in a low or high CRP group based on their CRP response during relapse and demographic and clinical features were compared. RESULTS: Overall, a positive correlation between CRP levels, number of relapses, and severity of relapse was found (respectively rs= 0.31, P < 0.01 and rs= 0.50, P < 0.001). Employing a cut-off level of 15 mg/L, the index CRP level was found to discriminate patients with respect to the number of relapses per year, as well as for severity of relapses (respectively 0.25.16 vs 0.36.24, P < 0.05 and 4.4.2 vs 3.2.1 on a 10-point visual analogue scale, P < 0.001 for the high CRP and low CRP groups respectively). In addition, the high CRP group showed more cumulative days of prednisone use per year (107.05), as well as a better response to infliximab (93 % vs 33 %, P = 0.06).CONCLUSION: A higher CRP level during relapse seems to be associated with a more severe clinical course of disease.

    Unlike bacterial infections, the value of procalcitonin (PCT) in detecting fungal infections in leukaemia patients is not clear. To determine whether the monitoring of PCT coupled with C-reactive protein (CRP) and fibrinogen (Fib) could be helpful in the management of pulmonary aspergillosis (IPA) or mucormycosis (PM), we retrospectively analysed the evolution of PCT, CRP and Fib levels in 94 leukaemia patients with proven/probable IPA (n = 77) or PM (n = 17) from D-12 to D12 relative to IFI onset defined as D0. Overall, 2140 assays were performed. From D-12 to D0, 12%, 5% and 1.4% of patients had PCT >0.5, 1 and 1.5 μg l(-1) , respectively, while CRP was >50, 75 and 100 mg l(-1) in 84%, 70% and 57% and Fib was >4, 5 and 6 g l(-1) in 96%, 80% and 61% of cases respectively (P 1.5 μg l(-1) , while CRP >100 mg l(-1) and Fib >6 g l(-1) were observed in 80% and 75% of cases respectively (P < 10(-7) ). In leukaemia patients, IPA or PM was accompanied by a significant increase in CRP and Fib while PCT remained low. PMID:26931315

    In order to study the relationship between serum C-reactive protein (CRP) levels, leuko-cyte count and carotid plaque in patients with ischemic stroke, carotid duplex examination was per-formed by high-definition imaging (HDI) 5000 triplex system. Serum CRP was measured by nephe-lometry within 72 h after index ischemic stroke. A lesion was considered a plaque in the presence ofa maximum intimal-medial wall thickness (IMT) 1.2 mm. Results of carotid ultrasonography weredivided into two groups: M1, normal (IMT <l. 2 mm) and M2, abnormal (IMT ≥1.2 mm). Theresults showed that the mean age of M2 was significantly older than that of M1 (69.7± 10.4 versus62.5±9.6, P=0. 001). The patients with hypertension and diabetes mellitus (78 %, 35 % re-spectively)in M2 were significantly more than those (52 %, 18 % respectively) in M1 (P<0.0l,P<0.05). There were 32 (65 % ) patients with elevated CRP levels in M2, but 33 (46 %) pa-tients with elevated CRP levels in M1, with the difference being significant between the two groups(P<0.05). The levels of serum glucose and leukocyte count (8. 1±5.5, 10.3±4.0, respectively)in abnormal CRP group were significantly higher than that of normal CRP group (6.4 ± 2.8, 8.7 ±3.4) (P<0.05, P<0.05); elevated CRP levels was found in 42 (62 %) patients with territory in-farction and 23 (43 %) patients with lacunar infarction respectively, with the difference being sig-nificant between these two groups (P<0.05). It was concluded that the elevation of CRP levelswas an significant clinical index for carotid plaque in patients with acute cerebral infarction.

  16. C-reactive (CRP) protein in transfusion dependent thalassaemic patients

    International Nuclear Information System (INIS)

    In thalassaemic patients iron overload, secondary to blood transfusion, results toxic effects by producing reactive radicals. Iron overload can be studied using serum ferritin level which has a direct correlation with the body's iron status. While oxidative damage can be studied using biomarker of inflammation like hsC-reactive proteins. Blood samples of 55 thalassaemic patients (39 males, 16 females) were collected from Fatmid Foundation (Hyderabad). The samples were analyzed for CBC, serum ferritin level and hsC-reactive proteins. High mean serum ferritin levels was found in all the patients regardless of the frequency of blood transfusion (4774.2135+-3143.3040 mu g/L), indicating the iron overload. High mean hsC-reactive protein was found (2.5151+-1.3712) with a positive correlation with ferritin (r= 0.8371198, p= 0.0000) and platelets (r= 0.43293443, p=0.000962175). C-reactive proteins serve as biomarker of various inflammatory conditions, progression of cardiovascular diseases and as indicator of morbidity and mortality. High C-reactive proteins in these patients indicate ongoing iron overload toxicity related damage in these patients. The estimation of hsC-reactive proteins and other biomarkers of inflammation and oxidation may help in better management of these patients. (author)

Results Fifty brachycephalic dogs were included in the study and the following information was studied: signalment, clinical signs, thoracic radiographs, blood work, ECG, components of BAOS, and CRP, Hp and cTnI levels. A high proportion of dogs with BAOS (88% had gastrointestinal signs. The prevalence of anatomic components of BAOS was: elongated soft palate (100%, stenotic nares (96%, everted laryngeal saccules (32% and tracheal hypoplasia (29.1%. Increased serum levels of biomarkers were found in a variable proportion of dogs: 14% (7/50 had values of CRP > 20 mg/L, 22.9% (11/48 had values of Hp > 3 g/L and 47.8% (22/46 had levels of cTnI > 0.05 ng/dl. Dogs with everted laryngeal saccules had more severe respiratory signs (p Conclusions According to the low percentage of patients with elevated levels of CRP and Hp, BAOS does not seem to cause an evident systemic inflammatory status. Some degree of myocardial damage may occur in dogs with BAOS that can be detected by cTnI concentration.

    Guidelines now recommend high-intensity statin therapy in all patients with proven atherosclerotic disease. Yet the impact of baseline lipoprotein and C-reactive protein (CRP) levels on measures of disease regression to this therapy are unknown. The aim of this study was to test the hypothesis that high-intensity statin therapy causes equivalent degrees of coronary atheroma regression irrespective of baseline lipoprotein and CRP levels. In 8 prospective randomized trials using serial coronary intravascular ultrasound, 1,881 patients who maintained or switched to 18- to 24 months of high-intensity statin therapy (rosuvastatin 40 mg or atorvastatin 80 mg) were stratified according to baseline lipoprotein and CRP levels. Changes in coronary percentage atheroma volume (PAV) and total atheroma volume (TAV) were evaluated. High-intensity statin therapy produced significant reductions from baseline in low-density lipoprotein cholesterol by 38.4%, non-high-density lipoprotein (HDL) cholesterol by 33.6%, triglycerides by 13.1%, and CRP by 33.3%, while increasing HDL cholesterol by 11.7% (p <0.001 for all). This was associated with regression of PAV by 0.7% and of TAV by 8.2 mm(3) (p <0.001 for both). No significant differences of changes in PAV and TAV were observed across baseline quintiles of low-density lipoprotein cholesterol, HDL cholesterol, non-HDL cholesterol, triglycerides, or CRP. Moreover, across all measured lipoproteins and CRP, most patients demonstrated plaque regression (defined as any change from baseline in PAV or TAV <0). In conclusion, high-intensity statin therapy attenuated the natural progression of coronary atherosclerosis in all strata of patients with coronary artery disease irrespective of baseline lipoprotein or CRP levels. These findings provide support for the latest United States guideline recommendations for the broad use of high-intensity statin therapy in all patients with atherosclerosis, regardless of baseline lipid status.

    Full Text Available Background: C-reactive protein (CRP is an acute phase reactant that is produced in response to diverse inflammatory stimuli, and is known predictor of cardiovascular disease risk. Aggressive and chronic periodontitis are two main forms of periodontal disease, which differ mainly in the method of disease progression. This study aims at determining and comparing the relative levels of serum CRP and alveolar bone loss in aggressive and chronic periodontitis patients. Materials and Methods: A total of 45 subjects, which were divided into 3 groups diagnosed as having generalized aggressive periodontitis (GAP, chronic generalized periodontitis (CGP and non-periodontitis controls (NP, were selected for the study. Venous blood samples were collected for quantitative CRP analysis using Turbidimetric immunoassay. Alveolar bone loss (ABL was measured at proximal sites of posterior teeth on a panoramic radiograph. The relationship between the mean ratio of ABL to root length and serum CRP levels was statistically analyzed using Student unpaired t-test, analysis of variance (ANOVA and Pearson′s correlation coefficient. Results: Mean CRP levels were significantly greater in both GAP (7.49±2.31 mg/l and CGP (4.88±1.80 mg/l groups as compared to NP (0.68±0.23 mg/l with P value <0.0001. The mean value of ABL (% was 31.58 in CGP group and 36.77 in the GAP group, the difference being statistically significant (P=0.0079. Correlation coefficient between CRP and ABL is 0.9310 in CGP, and 0.9252 in GAP, which indicates a positive correlation between both variables. Conclusion: Both forms of periodontitis are associated with increased systemic inflammatory response with aggressiveness of disease progression determining the degree of response.

    Full Text Available Atherosclerosis is a major complication of chronic renal failure. Microinflammation is involved in atherogenesis and is associated with uremia and dialysis. The role of dialysate water contamination in inducing inflammation has been debated. Our aim was to study inflammatory markers in patients on chronic dialysis, before and 3 to 6 months after switching the water purification system from deionization to reverse osmosis. Patients had demographic, clinical and nutritional information collected and blood drawn for determination of albumin, ferritin, C-reactive protein (CRP, interleukin-6, and tumor necrosis factor-alpha in both situations. Acceptable levels of water purity were less than 200 colony-forming units of bacteria and less than 1 ng/ml of endotoxin. Sixteen patients died. They had higher median CRP (26.6 vs 11.2 mg/dl, P = 0.007 and lower median albumin levels (3.1 vs 3.9 g/l, P < 0.05 compared to the 31 survivors. Eight patients were excluded because of obvious inflammatory conditions. From the 23 remaining patients (mean age ± SD: 51.3 ± 13.9 years, 18 had a decrease in CRP after the water treatment system was changed. Overall, median CRP was lower with reverse osmosis than with deionization (13.2 vs 4.5 mg/l, P = 0.022, N = 23. There was no difference in albumin, cytokines, subjective global evaluation, or clinical and biochemical parameters. In conclusion, uremic patients presented a clinically significant reduction in CRP levels when dialysate water purification system switched from deionization to reverse osmosis. It is possible that better water treatments induce less inflammation and eventually less atherosclerosis in hemodialysis patients.

    Full Text Available Context: Coronary atherosclerosis still presents one of the main causes of death. Efficacious prevention should focus on the early control of cardiovascular risk factors, including lipid profiles, which are unable early detect in subclinical cases. High-sensitive C-reactive protein (hs-CRP can prove to be an early cardiac risk predictor. Aims: 1 To compare hs-CRP levels between healthy volunteer with normal blood pressure and those with prehypertension, and 2 to use hs-CRP levels along with other risks to be a cardiac risk predictor. Setting and Design: This was a cross-sectional study for 6 months′ duration from January to June 2013 at Kudjab Hospital located in Udon Thani province, Thailand. Materials and Methods: Forty (40 healthy volunteers with prehypertension and 40 volunteers with normal blood pressure were included in the study. Both groups were similar in age range and sex. Twelve-hour (12-h fasting blood samples were collected from all the participants. Serum was assayed for hs-CRP and lipid profile. Results: All of parameters were statistically significant difference (P < 000.1. The hs-CRP level (6.27 ± 7.8 mg/L was elevated in the prehypertension group. The relative risk of hs-CRP for prehypertension was 6.3 with the odds ratio of 15.48, whereas the relative risk of lipid profiles for prehypertension prediction was only 1.28, with the odds ratio of 1.67. Statistical Analysis: SPSS version 11.0 using the unpaired t-test for comparing demographic data and blood parameters and risk prediction of hs-CRP and lipid profiles were calculated by relative risk with odds ratio [95% confidence interval (CI]. Conclusions: Hs-CRP is an early cardiac risk predictor even with normal lipid profile, and can help measure additional risk especially subclinical people such as prehypertension.

    Full Text Available Abstract Background Subclinical inflammation is a common phenomenon in patients on either continuous ambulatory peritoneal dialysis (CAPD or maintenance hemodialysis (MHD. We hypothesized that vitamin C had anti-inflammation effect because of its electron offering ability. The current study was designed to test the relationship of plasma vitamin C level and some inflammatory markers. Methods In this cross-sectional study, 284 dialysis patients were recruited, including 117 MHD and 167 CAPD patients. The demographics were recorded. Plasma vitamin C was measured by high-performance liquid chromatography. And we also measured body mass index (BMI, calculated as weight/height2, Kt/V, serum albumin, serum prealbumin, high-sensitivity C-reactive protein (hsCRP, ferritin, hemoglobin. The relationships between vitamin C and albumin, pre-albumin and hsCRP levels were tested by Spearman correlation analysis and multiple regression analysis. Patients were classified into three subgroups by vitamin C level according to previous recommendation 12 in MHD and CAPD patients respectively: group A: 4 ug/ml (> 22.8 umol/l, normal and above. Results Patients showed a widely distribution of plasma vitamin C levels in the total 284 dialysis patients. Vitamin C deficiency ( 14 ug/ml. The similar proportion of different vitamin C levels was found in both MHD and CAPD groups. Plasma vitamin C level was inversely associated with hsCRP concentration (Spearman r = -0.201, P = 0.001 and positively associated with prealbumin (Spearman r = 0.268, P 10hsCRP (P = 0.048 and positively with prealbumin levels (P = 0.002 adjusted for gender, age, diabetes, modality of dialysis and some other confounding effects. Conclusions The investigation indicates that vitamin C deficiency is common in both MHD patients and CAPD patients. Plasma vitamin C level is positively associated with serum prealbumin level and negatively associated with hsCRP level in both groups. Vitamin C deficiency

    Full Text Available Objectives: The present study was carried out to determine whether thyroid hormones affect lipid profile and levels of erithrocyte sedimentation rate (ESR, serum total homocysteine (t-hcy, leptin, fibrinogen, C-reactive protein (CRP in patients with hyperthyroidism.Materials and methods: This study was carried out on 23 hyperthroid subjects (3 men / 20 women, mean age 41.8 ± 2.4 years. Serum levels of homocysteine, leptin, fibrinogen, CRP, total cholesterol (TC, high-density lipoprotein cholesterol (HDL-C, low-density lipoprotein cholesterol (LDL-C and ESR were measured and body mass index (BMI were calculated before and after treatment of hyperthyroidism.Results: Pretreatment t-hcy, TC, LDL-C, HDL-C levels and BMI of patients were significantly lower than those of the post-treatment (p<0.001, for each variable. However, fibrinogen and ESR decreased after the treatment (p<0.001 and p<0.05, respectively. There were no differences in leptin and CRP levels between pre- and post-treatment periods. Pre and post treatment TC and LDL-C levels were negatively correlated with free triiodothyronine (fT3 levels (r=-0.588, p<0.01; r=-0.534, p<0.01; r=-0.543, p<0.01 and r =-0.653, p<0.01, respectively. Pre-treatment HDL-C was inversely correlated with TSH (r=-0.423, p<0.05. Pre-post- treatment LDL-C was negatively correlated with free thyroxine (fT4 levels (r=-0.536, p<0.001 and r=- 0.422, p<0.05 respectively. Pre-treatment TC was inversely correlated with fT4 (r=-0.590, p<0.01.Conclusion: Hyperthyroidism is associated with high plasma fibrinogen and ESR levels. Elevated plasma fibrinogen and ESR levels may be a possible explanation for the high cardiovascular morbidity among hyperthyroidic subjects. These changes may reflect low-grade inflammation or disturbances in coagulation in hyperthyroidism.

    Full Text Available Background: Stroke is a heterogeneous disease with several risk factors. High sensitivity C-reactive protein (hsCRP is a marker for cardiovascular and cerebrovascular diseases. Recent studies have shown that high hsCRP level is a risk factor for ischemic stroke. The objective of our study was to investigate the association of high hsCRP(> 3 mg/L levels with ischemic stroke and its subtypes in Indian patients.Methods: We recruited 210 consecutive acute stroke patients and 150 age and sex matched controls. Stroke patients were admitted within 72 hours of onset, at Yashoda Hospital, Hyderabad, India. The study period was from January 2011 to December 2012. All patients underwent tests as per standard protocol for stroke workup. Serum hsCRP level was assessed in all stroke patients and controls on the day of admission.Results: The mean hsCRP was significantly higher in stroke patients (3.8 ± 2.5 than controls (1.8 ± 1.5 (P < 0.001. High hsCRP had higher frequency in stroke patients 130 (61.9% compared to controls 10 (6.6%, P < 0.001. High hsCRP level was more prevalent in the stroke subtypes of cardioembolic stroke (83.3% and large artery atherosclerosis (72%. High hsCRP level was significantly associated with hypercholesterolemia (P = 0.001, age(P = 0.01, and mortality (0.04. After adjustment of regression analysis it was observed that high level hsCRP is independently associated with acute ischemic stroke (Odds 4.5; 95% CI: 2.5-12.2; especially the stroke subtypes of cardioembolic stroke, (odds ratio 3.4, 95% CI: 1.9-10.5 and large artery atherosclerosis (odds ratio 2.1, 95% CI: 1.5-3.8.Conclusion: High hsCRP level is strongly associated with and an independent predictor of acute ischemic stroke. The association was found in all ischemic stroke subtypes.

    Previous studies showed that C-reactive protein (CRP), an inflammatory marker, was associated with stroke severity and long-term outcome. However, the relationship between the acute-phase CRP level and discharge outcome has received little attention. We prospectively studied 301 patients with acute ischemic stroke (over a period of two weeks) from two hospital stroke wards and one rehabilitation department in Henan, China. Patients’ demographic and clinical data were collected and evaluated at admission. Poor discharge outcome was assessed in patients at discharge using the Modified Rankin Scale (MRS > 2). Multivariate logistic regression analysis was performed to determine the risk factors of poor discharge outcome after adjusting for potential confounders. Poor discharge outcome was observed in 78 patients (25.9%). Univariate analyses showed that factors significantly influencing poor discharge outcome were age, residence, recurrent acute ischemic stroke, coronary heart disease, the National Institutes of Health Stroke Scale (NIHSS) score at admission, non-lacunar stroke, time from onset of stroke to admission, CRP, TBIL (total bilirubin), direct bilirubin (DBIL), ALB (albumin), FIB (fibrinogen) and D-dimer (p < 0.05). After adjusting for age, residence, recurrent ischemic stroke, coronary heart disease, NIHSS score at admission, lacunar stroke, time from onset of stroke to admission, CRP, TBIL, DBIL, ALB, FIB and D-dimer, multivariate logistic regression analyses revealed that poor outcome at discharge was associated with recurrent acute ischemic stroke (OR, 2.115; 95% CI, 1.094–4.087), non-lacunar stroke (OR, 2.943; 95% CI, 1.436–6.032), DBIL (OR, 1.795; 95% CI, 1.311–2.458), and CRP (OR, 4.890; 95% CI, 3.063–7.808). In conclusion, the CRP level measured at admission was found to be an independent predictor of poor outcome at discharge. Recurrent acute ischemic stroke, non-lacunar stroke and DBIL were also significantly associated with discharge

  12. Clinical significance of preoperative serum vascular endothelial growth factor, interleukin-6, and C-reactive protein level in colorectal cancer

    International Nuclear Information System (INIS)

    Angiogenesis is a multistep process in which many growth factors and cytokines have an essential role. Vascular endothelial growth factor (VEGF) is a potent angiogenic agent that acts as a specific mitogen for vascular endothelial cells through specific cell surface receptors. The interleukin-6 (IL-6) pathway is another mechanism linking angiogenesis to malignancy. C-reactive protein (CRP), a representative marker for inflammation, is known for its association with disease progression in many cancer types. The aim of this study was to determine preoperative serum levels of VEGF, IL-6, and CRP in colorectal carcinoma, and to correlate them with disease status and prognosis. A 132 of 143 patients who underwent curative resection for colorectal cancer were enrolled in this study. 11 patients with resection margin positive were excluded. Factors considered in analysis of the relationship between VEGF, IL-6, and CRP and histological findings. Patient prognosis was investigated. Serum levels of VEGF and IL-6 were assessed using Enzyme-Linked Immuno-Sorbent Assay (ELISA), and CRP was measured using immunoturbidimetry. Median follow-up duration was 18.53 months (range 0.73-43.17 months) and median age of the patients was 62 years (range, 26-83 years). Mean and median levels of VEGF and CRP in colorectal cancer were significantly higher than in the normal control group; 608 vs. 334 pg/mL and 528 (range 122-3242) vs. 312 (range 16-1121) (p < 0.001); 1.05 mg/dL vs. 0.43 mg/dL and 0.22 (range 0.00-18.40) vs. 0.07 (range 0.02-6.94) (p = 0.002), respectively. However mean and median level of IL-6 in patients were not significantly higher than in control; 14.33 pg/mL vs. 5.65 pg/mL and 6.00 (range 1.02-139.17) vs. 5.30 (4.50-13.78) (p = 0.327). Although IL-6 and CRP levels were not correlated with other pathological findings, VEGF level was significantly correlated with tumor size (p = 0.012) and CEA (p = 0.038). When we established the cutoff value for VEGF (825 pg/mL), IL-6 (8

  13. Evaluation of Serum Levels of Pregnancy Associated Plasma Protein-A, Tumor Necrosis Factor-alpha and Highly Sensitive C-Reactive Protein in Diabetic Children

    International Nuclear Information System (INIS)

    Recent evidence favours the primary role of cellular auto immunity and its humoral mediators in the pathogenesis and follow up of children with type 1 diabetes mellitus (type 1 DM). The present study is carried out to investigate serum levels of pregnancy associated plasma protein-A (PAPP-A), tumor necrosis factor-alpha (TNF-alpha ) and highly sensitive C-reactive protein (hs-CRP) in children with type 1 DM. Potential role of body mass index (BMI) was evaluated. Circulating levels of TNF-alpha, PAPP-A and hs-CRP are significantly increased in children with type 1 DM as compared with healthy subjects suggesting activation of inflammatory immune response system. A significant negative correlation was obtained between TNF-alpha and BMI in diabetic patients. This is highly suggestive of the availability of these non invasive indices to help further examining type 1 DM pathophysiology and monitoring pharmacological interventions to interfere with disease development and progression.

    2002-05-01

    Full Text Available Abstract Background Serum C-reactive protein (CRP has been identified in prospective epidemiological research as an independent risk marker for cardiovascular disease. In this paper, short-term biological variation of CRP is documented and a strategy to test the reliability of a single CRP sample is proposed. Methods Data were obtained from three groups of healthy volunteers: men, no oral contraceptives (OC-using women and OC-using women. Blood samples were obtained 3 times in men and twice in women during a workweek. Results and discussion CRP values were highest in the OC-using women, followed by the men, and lowest in the no OC-using women. Averaged over the three groups the within-subject coefficients of variation (CVi was 49.24% for CRP, and 29.90% for lnCRP. Using the repeated measures, individual samples were identified that reflected a 'suspicious' unreliable high value, i.e. a value that was more than 2 standard deviations higher than the lowest value obtained from the same subject. In an a posteriori analysis, three strategies to identify these suspicious high CRP values were then tested. In terms of maximizing detection of suspicious values and minimizing unnecessary resampling, best results were obtained for the most pragmatic criterion of using an absolute level, stratified for gender, and OC-use, to decide whether a second sample should be obtained. Conclusion A single high CRP value must be followed by re-sampling when it is above 1.75 mg/l for men, above 1.00 mg/l for no OC-using women, and above 2.00 mg/l for OC-using women.

    Objective To identify potential relationships between plasma 25OHD, C-reactive protein (CRP), coronary artery atherosclerosis (CAA), and coronary artery remodeling in monkeys consuming atherogenic diets. Methods Female cynomolgus monkeys (n=74) were fed a casein-lactalbumin (C/L) based, moderately atherogenic diet for 12 months. They then consumed either a soy (n=35) or C/L (n=39) based diet for 32 months. CRP concentrations were then determined and monkeys underwent surgical menopause. Each diet group was then re-randomized to receive soy (n=36) or C/L (n=38). After 32 post-menopausal months, 25OHD, CRP, CAA, and coronary artery remodeling were determined. All monkeys received a women’s equivalent of 1,000 IU/day of 25OHD3 and 1,200 mg/day of calcium, throughout the study. Results The pre and post-menopausal dietary protein sources had no effect on post-menopausal 25OHD3 concentrations (p=0.6). Across treatment groups, there was a statistically significant inverse relationship between 25OHD3 concentrations and CRP at necropsy (r=-0.35, p=0.003). A significant inverse correlation between 25OHD3 concentration and the change in CRP, from pre-menopause to post-menopause, was observed (r=-0.32, p=0.007). The significant associations identified between plasma 25OHD3 and CRP remained after controlling for postmenopausal diet. Those monkeys with a greater increase in CRP also had significantly more CAA and less ability to maintain normal lumens by remodeling. Conclusions Higher plasma concentrations of 25OHD3 were associated with lower CRP. Lower CRP was associated with less coronary atherosclerosis and improved coronary artery remodeling. These findings suggest that 25OHD3 concentrations are associated with an anti-inflammatory state and may support an association between oral 25OHD3 and cardioprotection. PMID:22713861

    Objective:To explore the correlation between serum levels of C - reactive protein( CRP )/high - sensitivity C - reactive protein( hs - CRP ) and radiation dermatitis. Methods: One hundred and three patients with carcinoma were included. Stereotactic radiotherapy ( SRT ) was applied for 22 patients and radiation therapy ( RT ) for 81 patients. Weekly, radiation dermatitis was assessed according to EORTC( European Organization for Research and Treatment of Cancer )criteria and serum CRP/hs - CRP were tested. Results: The mean serum levels of CRP ( 54. 6 ±10.9 vs 17.3 ±2.5, P=0.004)/hs-CRP( 10. 4 ± 1. 9 vs 5. 6 ±0. 6, P =0.017) for SRT - treating patients were significantly higher than those treated with RT. In terms of radiation dermatitis, none was seen for SRT - trea - ting patients. For RT - treating patients, grade 0 dermatitis was seen in 2 patients, grade I in 25, grade II in 29, grade Ⅲ in 19 and grade Ⅳ in 6. The mean serum levels of CRP/hs - CRP were escalated with the severity of radiation dermatitis ( CRP: correlation coefficient 0.48, P <0. 001; hs - CRP: correlation coefficient 0. 25, P = 0. 05 ). And patients with grade 3/4 dermatitis had significantly higher mean serum level of CRP than those with grade 2 or lower dermatitis ( 33. 5 ±5. 9 vs 10. 1 ±1.8, P =0. 001 ). However, for hs - CRP, the difference was not significant ( 7. 5 ± 1. 2 vs 4. 9 ± 0. 7 , P = 0. 06 ). Conclusion: Serum level of CRP/hs - CRP increased after radiation. They had positive correlation with the severity of radiation dermatitis in RT - treating patients. Serum level of CRP was significantly higher in patients with grade 3/4 dermatitis than those with grade 2 or lower dermatitis. However, no such correlation was found in SRT - treating patients.%目的:探讨C反应蛋白(CRP)和超敏C反应蛋白(hs-CRP)与放疗皮肤反应之间的相关性.方法:观察103例接受放疗的恶性肿瘤患者的皮肤反应,同时每周检测患者血清中CRP和hs-CRP

    2016-01-01

    Full Text Available To test the statistical association of the CRP and SAA1 locus variants with their corresponding circulating levels and metabolic and inflammatory biomarker levels by using mediation analysis, a sample population of 599 Taiwanese subjects was enrolled and five CRP and four SAA1 variants were genotyped. Correlation analysis revealed that C-reactive protein (CRP and serum amyloid A (SAA levels were significantly associated with multiple metabolic phenotypes and inflammatory marker levels. Our data further revealed a significant association of CRP and SAA1 variants with both CRP and SAA levels. Mediation analysis revealed that SAA levels suppressed the association between SAA1 genotypes/haplotypes and CRP levels and that CRP levels suppressed the association between CRP haplotypes and SAA levels. In conclusion, genetic variants at the CRP and SAA1 loci independently affect both CRP and SAA levels, and their respective circulating levels act as suppressors. These results provided further evidence of the role of the suppression effect in biological science and may partially explain the missing heritability in genetic association studies.

    Our meta-analysis was designed to obtain the correlation between thrombomodulin (TM) and high-sensitive C-reactive protein (hs-CRP) levels and the development of cerebral infarction (CI). Case-control studies relevant to the role plasma TM levels and serum hs-CRP levels in the development of CI were retrieved both electronically and manually and further screened according to a predetermined inclusion and exclusion criteria. All enrolled studies were analyzed for meta-regression analyses, sensitivity analyses, and assessments of publication bias. Comprehensive Meta-analysis 2.0 software (CMA 2.0) was used for statistical analysis. A total of 359 studies were initially retrieved, and 13 studies were eventually recruited into our meta-analysis with a total of 881 CI patients (plasma TM levels: n = 513; serum hs-CRP levels: n = 368) and 1067 healthy controls. The results of our meta-analysis suggested that plasma TM levels and serum hs-CRP levels in CI patients were significantly higher than those in healthy controls. In conclusion, increased plasma TM levels and serum hs-CRP levels in CI patients were associated with the development of CI in Asians. PMID:26133301

  17. Analysis of the variation levels of APN, insulin, sensitive C-reactive protein and leptin in the serum of patients with type 2 diabetes mellitus

    International Nuclear Information System (INIS)

    To study the mechanism of pancreatic 13 cell dysfunction and tissue resistance to insulin, and to provide basis for early diagnosis and therapy of the disease, the levels of APN, insulin, sensitive C-reactive protein and leptin in the serum of patients with type 2 diabetes mellitus were determined. Altogether 184 untreatea type 2 diabetes mellitus patients, 30 normal people as the control group, and another 75 type 2 diabetes mellitus patients who have been treated for a year were enrolled in this study. The serum levels of the above indexes were determined by chemiluminescence immunoassay, enzyme immunoassay and radioimmunoassay. The results showed that there were obvious differences in the levels of insulin, leptin, C-reacting protein and insulin antibody between the normal control group and the group of the untreated type 2 diabetes mellitus patients (P<0.01), especially there was significant difference in the level of APN(P<0. 001). Among the 75 type 2 diabetes meltitus patients who have received a year's treatment, all the indexes except for APN and insulin antibody were decreased statistically, while the APN level was increased significantly (P<0.01) than that before the treatment. The determination of markers of type 2 diabetes mellitus is of great significance for its early diagnosis, therapy, prognosis and mechanism research. (authors)

    Full Text Available Ischemic stroke is one of the most common causes of death worldwide and is most often caused by thrombotic processes. We investigated the changes in hsCRP and homocysteine levels, two of these risk factors, during the acute period of ischemic stroke and evaluated the relationship between these levels and the short-term prognosis. HsCRP and homocysteine levels were measured at the 2nd, 5th, and 10th days in forty patients admitted within second of an ischemic stroke. The clinical status of the patients was simultaneously evaluated with the Scandinavian stroke scale. The results were compared with 40 healthy control subjects whose age and sex were matched with the patients. The mean hsCRP levels of the patients were 9.4±7.0 mg/L on the 2nd day, 11.0±7.4 mg/L on the 5th day, and 9.2±7.0 mg/L on the 10th day. The mean hsCRP level of the control subjects was 1.7±2.9 mg/L. The mean hsCRP levels of the patients on the 2nd, 5th, and 10th days were significantly higher than the control subjects (P<.001. The patients' mean homocysteine levels were 40.6±9.6μmol/L on the 2nd day, 21.7±11.1μmol/L on the 5th day, and 20.7±9.2μmol/L on the 10th day. The mean homocysteine level of the control subjects was 11.2±1.1μmol/L. The homocysteine levels of the patients were higher than the control subjects at all times (P<.01. In conclusion, patients with stroke have a higher circulating serum hsCRP and homocysteine levels. Short-term unfavorable prognosis seems to be associated with elevated serum hsCRP levels in patients with stroke. Although serum homocysteine was found to be higher, homocysteine seems not related to prog nosis.

We retrospectively analyzed consecutive natalizumab-treated multiple sclerosis patients who underwent a JCV antibody test through a two-step enzyme-linked immunosorbent assay (STRATIFY test to the measure of serum usCRP levels, and to perform blood and urine JCV PCR. The studied cohort included 97 relapsing–remitting patients (60 women. Fifty-two patients (53.6% tested positive for anti-JCV antibodies. PCR showed JCV DNA in the urine of 30 out of 83 (36.1% patients and 28 out of 44 seropositive patients (63.6%, with a 6.7% false-negative rate for the STRATIFY test.

    C-reactive protein(CRP) is a commonly used tool in emergency department(ED), especially in febrile and infectious patients.It was identified in1930 and was subsequently classified into an "acute phase protein", an early indicator of infectious or inflammatory situations in theED, CRP must be a diagnostic reference and no single value can be indicated to rule in or rule out a specific diagnosis or disease.CRP is a comprehensively assisted tool for evaluation and diagnosis of tissue damage(rheumatologic diseases, stroke, cancer, pancreatitis, burn injury, sepsis and gout) and infection(urinary tract infection, pelvic inflammatory disease, meningitis and lung infection).It can be used for treatment monitoring and severity evaluation in pneumonia, pancreatitis, pelvic inflammatory disease(PID), and urinary tract infections(UTI).Otherwise, it also plays the role of prognostic indicator of acute coronary syndrome.C-reactive protein adds little to the diagnosis of pneumonia, urinary tract infections, and pancreatitis.A single CRP value should not straightly make the decision to treat these patients.That is,CRP has no role in diagnosing these clinical entities, and a normalCRP level should never delay antibiotic coverage inED.Faster and more interpretable tools such as image studies(X-ray, sonography and computed tomography) are available to help diagnose suspected cases of aortic dissection, appendicitis, cholecystitis, pancreatitis, pneumonia and stroke inED.

    C-reactive protein (CRP) is an acute-phase reactant that increases in the circulation in response to a variety of inflammatory stimuli. Elevated levels in serum during several infectious diseases have been reported. In this study, a highly sensitive CRP enzyme immunoassay was used to evaluate serum CRP values in patients with viral and atypical bacterial infections. Patients (n = 139) with different viral or atypical bacterial infections (systemic or respiratory) and healthy controls (n = 40) were tested for circulating CRP values. High levels of IgM antibodies against several viruses: Dengue virus (n = 36), Cytomegalovirus (n = 9), Epstein Barr virus (n = 17), Parvovirus B19 (n = 26), Herpes simplex 1 and 2 virus (n = 3) and Influenza A and B (n = 8) and against atypical bacteria: Legionella pneumophila (n = 15), Mycoplasma pneumoniae (n = 21) and Coxiella burnetii (n = 4) were found. High values of CRP in infected patients compared with controls (P < 0.001) were found; however, no significant differences between viral and atypical bacterial infections were found. Low levels of CRP in respiratory and Coxiella burnetii infections compared with exanthematic viral and other atypical bacterial infections were found. This study suggests that CRP values are useful to define viral and atypical bacterial infections compared with normal values, but, it is not useful to define type of infection. PMID:26241406

    Full Text Available Objective. Depression has been associated with increased cardiovascular disease risk, and a depression-related elevation of high sensitivity C-reactive protein (hs-CRP has been proposed as a possible mechanism. The objective of this paper is to examine association between depression and high sensitivity C-reactive protein (hs-CRP. Methods. Subjects consisted of 508 healthy adults (mean age 48.5 years; 49% women, 88% white residing in central Massachusetts. Data were collected at baseline and at quarterly intervals over a one-year period per individual. Multivariable linear mixed models were used to assess the association for the entire sample and by gender. Results. The mean Beck Depression Inventory score was 5.8 (standard deviation (SD 5.4; median 4.3, and average serum hs-CRP was 1.8 mg/L (SD 1.7; median 1.2. Results from the multivariable linear mixed models show that individuals with higher depression scores have higher levels of hs-CRP. Analyses by gender show persistence of an independent association among women, but not among men. Body mass index (BMI = weight(kg/height(m2 appears to be a partial mediator of this relationship. Conclusion. Depression score was correlated to hs-CRP levels in women. Further studies are required to elucidate the biological mechanisms underlying these associations and their implications.

    Objective: To study the clinical diagnostic value of determination of serum ischemia modified albumin (IMA), homocysteine (Hcy) and high-sensitivity C-reactive protein (hs-CRP) levels in patients with acute coronary syndrome (ACS). Methods: Serum IMA (with albumin-cobalt binding assay), Hcy (with ELISA) and hs-CRP (with RIA) levels were determined in 73 patients with ACS within 3 hours after onset of chest pain and 40 controls. Results: The sensitivity of IMA was 87.67%, the specificity was 100%. The area under curve of ROC was 0.985 (95% confidence interval 0.969 ∼ 1.001). All the figures were higher than those of Hcy and hs-CRP. Combined determination of IMA, Hcy and hs-CRP, would increass the sensitivity to 97.26%. Conclusion: IMA is one of the earliest sensitive indicators for clinical diagnosis of early myocardial ischemia in patients with ACS. Combined determination of IMA, Hcy and hs-CRP would be even more sensitive. (authors)

    Full Text Available Abstract Background and Aim Currently, no data on the optimal time point after acute ischemic stroke (IS at which high-sensitivity C-reactive protein (hs-CRP level is most predictive of unfavorable outcome. We tested the hypothesis that hs-CRP levels during both acute (48 h after IS and convalescent (21 days after IS phases are equally important in predicting 90-day clinical outcome after acute IS. We further evaluated the impact of erythropoietin (EPO, an anti-inflammatory agent, on level of hs-CRP after acute IS. Methods Totally 160 patients were prospectively randomized to receive either EPO therapy (group 1, n = 80 (5,000 IU each time, subcutaneously at 48 h and 72 h after acute IS, or placebo (group 2, n = 80. Serum level of hs-CRP was determined using ELISA at 48 h and on day 21 after IS and once in 60 healthy volunteers. Results Serum level of hs-CRP was substantially higher in all patients with IS than in healthy controls at 48 h and day 21 after IS (all p 0.5. Multivariate analysis showed that hs-CRP levels (at 48 h and day 21 were independently predictive of 90-day major adverse neurological event (MANE (defined as recurrent stroke, NIHSS≥8, or death (all p Conclusion EPO therapy which was independently predictive of freedom from 90-day MANE did not alter the crucial role of hs-CRP levels measured at 48 h and 21-day in predicting unfavorable clinical outcome after IS.

  14. E valuation and clinical significance of serum C-reactive protein and homocysteine level in obstructive sleep apnea/hypopnea syndrome complicated with coronary heart disease patients

    International Nuclear Information System (INIS)

    Objective: To explore the relationship between homocysteine (HCY) and C-reactive protein (CRP) in obstructive sleep apnea/hypopnea syndrome (OSAHS) patients and OSAHS patients complicated with coronary heart disease by detecting the scrum level of HCY and CRP on the mechanism of OSAHS complicated with coronary heart disease. Methods: Ninety-one patients were divided into three groups, 30 patients as control group, 36 patients as OSAHS group, and 25 patients as OSAHS complicated with CHD group. Serum HCY level was detected through chemiluminescence. Serum CRP level was detected through radioimmunity. The serum level of HCY and CRP was compared among these groups. OSAHS patients were divided into mild OSAHS subgroup, moderate OSAHS subgroup and severe OSAHS subgroup. The morbidity rate of CHD and the serum level of HCY and CRP were compared among these subgroups. Meanwhile the parameters of polysomnogram such as activity apnea-hypopnea index (AHI) and blood oxygen saturation (SaO2) were compared between OSAHS group and OSAHS complicated with coronary heart disease group. Results: (1) There was significant difference among the serum level of HCY and CRP of control group, OSAHS group and OSAHS complicated with CHD group (FHCY=15.80, FCRP=19.21, P allHCY=4.74, tCRP=5.14, P all HCY=7.31, tCRP=8.17, P all 2=6.96, χ2=4.18, PHCY=16.38, FCRP=12.97, P all2 of OSAHS group and OSAHS complicated with CHD group (tAHI=5.46, percentage of SaO2 2: t=4.68, average lowest SaO2: t=3.65, longest duration of disordered breathing events: t=4.73, P all<0.01 ). Conclusion: The serum level of HCY and CRP rose because of hypoxia in OSAHS patients,and might play an important role in the mechanism of OSAHS complicated with CHD. (authors)

    High-dose vancomycin treatment increases the likelihood of vancomycin-related nephrotoxicity. C-reactive protein (CRP) is a sensitive marker of systemic inflammation. In this study, we evaluated the pre-treatment serum CRP level as a risk factor of the development of nephrotoxicity in patients receiving high total daily doses (>2.5 g) of vancomycin. Data extracted from medical records for 174 patients who received total daily doses of >2.5 g of intravenous vancomycin for a minimum of 48 h and had their serum CRP level and erythrocyte sedimentation rate tested within 24 h before vancomycin treatment were subject to final analyses. Univariate analyses showed that patients who developed nephrotoxicity during vancomycin treatment had significantly higher median vancomycin serum concentration, duration of vancomycin treatment, and the serum CRP level within 24 h before vancomycin treatment than the non-nephrotoxicity group. Multivariate logistic regression analysis showed that after adjustment for potential confounders, median vancomycin serum concentration, duration of treatment, serum CRP level within 24 h before vancomycin treatment, and nephrotoxic medication were found significantly associated with the development of nephrotoxicity. This was confirmed by multivariate hazard ratio analysis after adjustment for potential confounders. In conclusion, this study provides the first evidence supporting the fact that the serum CRP level within 24 h before vancomycin treatment is an independent risk factor for the development of nephrotoxicity in patients receiving total daily doses of >2.5 g of vancomycin. Therefore, the serum CRP level within 24 h before vancomycin treatment could be a potential biomarker or prognostic factor for the development of vancomycin nephrotoxicity. PMID:26919511

    Full Text Available Background: Recent epidemiological studies have shown that periodontal infection is a risk factor for a number of systemic diseases and conditions. In addition to the conventional risk factors, chronic infection and the subsequent generation of a systemic inflammatory response may be associated with this increased risk. Aims: This study was conducted to determine whether the presence of chronic periodontitis and subsequent non-surgical periodontal therapy could influence the serum levels of interleukin-6 and C-reactive protein (CRP in patients with severe chronic generalized periodontitis. Settings and Design: Participants were selected from subjects who attended the Department of Periodontics and Oral Implantololgy, Government Dental College, Thiruvananthapuram. Materials and Methods: Sera were obtained from 25 patients with periodontitis for baseline examination and reassessment after completion of treatment. As a control, sera were also obtained from 20 subjects without periodontitis. Interleukin-6 was determined by sensitive enzyme-linked immunosorbent assay, and high-sensitivity CRP (hsCRP was measured using latex turbidometric immunoassay. Statistical Analysis: Data were analyzed using computer software, Statistical Package for Social Sciences (SPSS version 10. Results: The level of interleukin-6 and hsCRP in the sera of periodontitis patients was seen to be higher than those of healthy controls. Interleukin-6 level tended to decrease with improvement of the periodontal condition following treatment and approached that of control subjects, and this decline was statistically significant. The hsCRP levels also showed a decreasing trend following periodontal treatment. Conclusions: In this study, we were able to show that periodontal disease significantly affects the serum levels of systemic inflammatory markers and that non-surgical periodontal therapy could bring about a decrease in the levels of these inflammatory markers.

    Full Text Available Purpose : The objective of this study is to determine the change of C-reactive protein (CRP levels in the peripheral blood of preterm infants at birth according to the stage of intrauterine inflammation. Methods : A total of 187 infants (&lt;32 weeks of gestation were divided into a “no histologic chorioamnionitis” [HCAM (-, n=85] group and a “histologic chorioamnionitis” [HCAM (+, n=102] group according to placental pathologic findings. Furthermore, the HCAM (+ group was subdivided into a “funisitis” [F (+, n=49] group and a “no funisitis” [F (-, n=53] group and also into a “funisitis/amnionitis” [FA (+, n=58] group and an “isolated chorio-deciduitis” [FA (-, n=44] group. High-sensitivity CRP levels in the peripheral blood at birth were measured. Results : Peripheral blood CRP levels were significantly higher in the HCAM (+, F (+, F (-, and FA (+ groups than in the HCAM (- group, but were not significantly different between the FA (- and HCAM (- groups. In addition, peripheral blood CRP levels were significantly higher in the F (+ and FA (+ groups than in the F (- and FA (- groups, respectively. For identification of amnionitis or funisitis, a cut-off value of 0.02 mg/dL was chosen. Clinical chorioamnionitis, proven early onset sepsis, histologic chorioamnionitis, and funisitis had higher incidences in infants with peripheral blood CRP levels higher than 0.02 mg/dL. Conclusion : The present study shows that peripheral blood CRP levels at birth in preterm infants born before 32 weeks’ gestation is significantly increased in amnionitis or funisitis and might reflect the progress of histologic chorioamnionitis.

    Introduction Studies on Mean Platelet Volume (MPV) in children with Sleep Disordered Breathing (SDB) report conflicting results and the hypothesis of an intermittent hypoxemia leading to a systemic inflammation is reaching consensus. Vitamin D exerts anti-inflammatory properties and its deficiency has been supposed to play a role in sleep disorders. Emerging interest is rising about Primary Snoring (PS) since it is reasonable that also undetectable alteration of hypoxia might predispose to an increased production of inflammatory mediators. In this perspective, in a group of children affected by SDB, our aim was to investigate MPV, vitamin D and C Reactive Protein (CRP) levels, which had been previously evaluated separately in different studies focused only on Obstructive Sleep Apnea Syndrome (OSAS). Materials and Methods We enrolled 137 children: 70 healthy controls (HC), 67 affected by SDB undergoing a polysomnographic evaluation, 22 with a diagnosis of PS and 45 with a diagnosis of OSAS. All patients underwent routine biochemical evaluations including blood cell counts, CRP and vitamin D. Results Children affected by SDB had a mean age of 8.49±2.19 and were prevalently males (23 females, 34%; 44 males, 66%). MPV levels were higher in OSAS and PS when compared to HC; platelet count (PLT) and CRP levels were higher while Vitamin D levels were lower in children with SDB when compared to HC. MPV levels were correlated with PLT (r = -0.54; pvitamin D (r = -0.39; pvitamin D, CRP and PLT and these variables significantly predicted MPV (F = 17.42, pvitamin D added statistically significantly to the prediction (pvitamin D levels in children with PS as well as in children with OSAS, and supports the underlying inflammation, hence, highlighting the importance of an early diagnosis of this previously considered benign form of SDB.

    Results: The mean value of serum C-RP in cases was 3.26+/-2.0 (mg/dl and in controls 0.57+/-0.34 (mg/dl with p<0.001. TSA in cases was 3.53+/-1.41 (mmol/L compared to controls 1.81+/-0.53 (mmol/L, p<0.001. There was a statistically significant positive correlation between C-RP and TSA (r=0.755, p<0.001. The mean value of Albumin in cases decreased (2.54+/-0.87 as compared to control (4.07+/-0.66 (p<0.001 showed negative correlation with C-RP (r= -0.418, p<0.01 and TSA (r= -0.728, p<0.001. There was a significant decrease in BMI among cases 19.95+/-3.17 compared to control 21.17+/-1.78 p<0.001. Conclusions: C- reactive protein in association with TSA has increased in COPD as a marker of systemic inflammation. Albumin and BMI decreased as a result of nutritional depletion. Patients with low BMI and low serum albumin level have greater risk of having exacerbation, acute respiratory failure than patients with normal BMI. [Int J Res Med Sci 2016; 4(4.000: 1209-1215

    Full Text Available INTRODUCTION: Ventilator-associated pneumonia (VAP is an important cause of mortality and morbidity in critically ill patients. We sought to determine the prognostic value of procalcitonin (PCT and C-reactive protein (CRP kinetics in critically ill patients who developed VAP. METHODS: Patients who were admitted to the intensive care unit (ICU and developed VAP were eligible. Patients were followed for 28 days after the pneumonia diagnosis and blood samples for PCT and CRP were collected on the day of the pneumonia diagnosis (D0, and days 3 (D3 and 7 (D7 after the diagnosis. Patients were grouped as survivors and non-survivors, and the mean PCT and CRP values and their kinetics were assessed. RESULTS: In total, 45 patients were enrolled. Of them, 22 (48.8% died before day 28 after the pneumonia diagnosis. There was no significant difference between the survivor and non-survivor groups in terms of PCT on the day of pneumonia diagnosis or CRP levels at any point. However, the PCT levels days 3 and 7 were significantly higher in the non-survivor group than the survivor group. Whereas PCT levels decreased significantly from D0 to D7 in the survivor group, CRP did not. A PCT level above 1 ng/mL on day 3 was the strongest predictor of mortality, with an odds ratio of 22.6. CONCLUSION: Serum PCT was found to be a superior prognostic marker compared to CRP in terms of predicting mortality in critically ill patients who developed VAP. The PCT level on D3 was the strongest predictor of mortality in VAP.

    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 β=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.

    The aim of this study was to determine the perioperative behavior of C-reactive protein (CRP) in Crohn's disease (CD) patients undergoing elective ileo-cecal (IC) resection and to identify association between perioperative CRP levels and endoscopic recurrence at 1 year. Study hypothesis was that perioperative CRP changes are disease specific and could detect subset of patients with more aggressive pathopysiology. Seventy-five patients undergoing IC resection for CD were prospectively enrolled. Serial CRP levels were assessed: preoperative, postoperative day 1 (POD1) and day 5 (POD5). CD patients' values were compared against same interval assessments of control groups undergoing right colectomy and appendicectomy. At POD1, the serum concentration increase was significantly higher in CD patients than in controls. Comparing with control groups, CRP levels remained remarkably high and showed a lower reduction in CD at POD5. Difference between groups was statistically significant. Optimal cutoff levels have been identified: serum CRP concentrations of >39.8 mg/l at POD1 and of >23.2 mg/l at POD5 have shown a significant association to endoscopic recurrence when using bivariate correlation. In this preliminary series, binary logistic regression could not demonstrate statistical relationship between endoscopic recurrence and any of the variables evaluated as prognostic factor. This is the only study so far that investigates and confirms a disease-specific upregulation of CRP response in the perioperative period for CD patients undergoing surgery. The postoperative CRP levels and kinetics seem to be related to the grade of mucosal inflammation and recurrence rate according to our 12 months endoscopic evaluation. PMID:27551522

  3. Diagnostic value of serum procalcitonin levels in children with meningitis: a comparison with blood leukocyte count and C-reactive protein

    Objectives: To determine the level of serum procalcitonin, blood leukocyte count (TLC) and C-reactive protein (CRP) in children with bacterial and non bacterial meningitis and document their efficacy in differential diagnosis. Also described are procalcitonin levels variation during treatment. Methods: From March 2005 to February 2008, we evaluated 38 clinically suspected meningitis patients in the paediatric departments, Al-Jedaany Hospital, Jeddah, KSA, for Serum procalcitonin, CRP, TLC and Lumbar punctures and CSF analysis. Patients were classified into bacterial meningitis group I (18) and non bacterial meningitis group II (20). Results: Serum PCT levels were significantly higher in bacterial meningitis (BM) 9 mean 4.8 +- 3.85 ng/ml (2.9-11.6)) compared with non bacterial meningitis (NBM) (mean 0.38 +- 0.25 ng/ml(0.31-0.61)) P< 0.001). Mean of all CSF parameters, TLC (15,000 +- 2,900 cell/ml(BM) and 9,500 +-1,105 cell/ml(NBM))and CRP (20 +- 6.8 mg/l (BM) and 12.5 +-12.0 mg/l(NBM))showed a zone of overlapping between the two groups. There is a positive correlation between serum PCT, TLC and CRP in bacterial and non bacterial meningitis cases but this relation becomes highly significant with bacterial meningitis positive group. Day 3 and day 6 treatment serum PCT was less than on admission levels (P<0.001). Conclusion: PCT can be used in the early diagnosis of bacterial meningitis and may be a useful adjunct in differentiating bacterial and non bacterial meningitis than CRP or TLC and diminishing the value of lumbar puncture performed 48-72 hours after admission to assess treatment efficacy.

    Full Text Available The objective of our study is to compare the C-reactive protein (CRP levels with the delivered dose of dialysis in terms of Kt/V in patients undergoing maintenance hemodialysis (HD. This is a comparative, cross-sectional survey. The study was conducted at the HD unit of the Shaikh Zayed Hospital, Lahore, Pakistan. Patients who fulfilled the inclusion and exclusion criteria were enrolled in this study. The delivered dose of HD (Kt/V was assessed by an online clearance module (OCM in Fresenius machines at the end of every dialysis session and the weekly Kt/V was determined by adding all three Kt/V values. The serum CRP sample was taken after each session of HD and the mean CRP was calculated and considered elevated if it was >6 mg/dL. Both weekly Kt/V and CRP values were entered in a pre-designed proforma. Data were analyzed by using statistical software SPSS and P-value £0.05 was considered significant. Of 100 patients on maintenance HD, high serum CRP level (>6 mg/dL was found in 38 patients. When the Kt/V was compared with the CRP level, there was a negative correlation between the two parameters (r = 0.212, P = 0.032. Low Kt/V means dialysis inadequacy, which is associated with chronic inflammatory state, resulting in high CRP levels. We suggest that the quality of life of dialysis patients can be improved by offering an adequate dose of HD reflected by Kt/V ≥3.6/week.

    International Nuclear Information System (INIS)

    Objective: To explore the dynamic of high-sensitivity C-reactive protein (hs-CRP) and its correlation with insulin resistance (IR) during different stages of gestational diabetes mellitus (GDM). Methods: Thirty-two subjects with GDM and thirty-one cases of normal glucose tolerance (NGT) pregnant women were enrolled in the study, fasting insulin (FINS) were determined by radioimmunoassay, the fasting blood glucose (FBG) was measured by using glucose oxidase, immunoturbidimetry performed to evaluate serum hs-CRP levels. Tests repeated for each group according different stages of prenatal 25-28 weeks, 29- 32 weeks, 37-38 weeks and postpartum 6-8 weeks. IR was assessed by the homeostasis model assessment insulin resistance index (HOMA-IR). Results: (1)Serum hs-CRP levels in NGT and GDM had few change with gestational age, but both significantly decreased at postpartum. (2)Serum hs-CRP levels in GDM significantly increased than NGT in the same stage (t was 7.31, 7.78, 6.33, respectively, P<0.01 ). (3) HOMA-IR in GDM significantly increased than NGT in the same gestational stage (t was 31.18, 31.10, 28.39, respectively, P<0.01). (4)Pearson correlation analysis showed that FBG, FINS and hs-CRP had significant association with HOMA-IR (regression coefficient of 0.478, 0.902, 0.293, respectively, P<0.01). Multiple regression analysis identified FINS, FBG and hs-CRP as the factors significantly affecting HOMA-IR (regression coefficient of 0.441, 0.876, 0.261, respectively, P<0.01). Conclusion: Serum hs-CRP levels in GDM had few change with gestational age, but all significantly increased than NGT in the same stage, and which were the most significant factors affecting HOMA-IR.

    Full Text Available BACKGROUND: In a previous report by our group, high levels of apolipoprotein E (apoE were demonstrated to be associated with risk of incident cardiovascular disease in women with high levels of C-reactive protein (CRP in the setting of both low (designated as HR1 subjects and high (designated as HR2 subjects levels of high-density lipoprotein cholesterol (HDL-C. To assess whether apolipoprotein A-II (apoA-II plays a role in apoE-associated risk in the two female groups. METHODOLOGY/PRINCIPAL: Outcome event mapping, a graphical data exploratory tool; Cox proportional hazards multivariable regression; and curve-fitting modeling were used to examine apoA-II influence on apoE-associated risk focusing on HDL particles with apolipoprotein A-I (apoA-I without apoA-II (LpA-I and HDL particles with both apoA-I and apoA-II (LpA-I:A-II. Results of outcome mappings as a function of apoE levels and the ratio of apoA-II to apoA-I revealed within each of the two populations, a high-risk subgroup characterized in each situation by high levels of apoE and additionally: in HR1, by a low value of the apoA-II/apoA-I ratio; and in HR2, by a moderate value of the apoA-II/apoA-I ratio. Furthermore, derived estimates of LpA-I and LpA-I:A-II levels revealed for high-risk versus remaining subjects: in HR1, higher levels of LpA-I and lower levels of LpA-I:A-II; and in HR2 the reverse, lower levels of LpA-I and higher levels of LpA-I:A-II. Results of multivariable risk modeling as a function of LpA-I and LpA-I:A-II (dichotomized as highest quartile versus combined three lower quartiles revealed association of risk only for high levels of LpA-I:A-II in the HR2 subgroup (hazard ratio 5.31, 95% CI 1.12-25.17, p = 0.036. Furthermore, high LpA-I:A-II levels interacted with high apoE levels in establishing subgroup risk. CONCLUSIONS/SIGNIFICANCE: We conclude that apoA-II plays a significant role in apoE-associated risk of incident CVD in women with high levels of HDL-C and CRP.

    Chronic inflammation may play a role in ovarian carcinogenesis. We examined associations between 3 plasma biomarkers of inflammation-C-reactive protein (CRP), interleukin 6, and tumor necrosis factor α receptor 2-and risk of invasive epithelial ovarian cancer in prospectively collected samples from the Nurses' Health Study (NHS; 1989-2010), Nurses' Health Study II (NHS II; 1996-2009), and the Women's Health Study (WHS; 1992-2011) and performed a meta-analysis including data from previous publications. Associations with ovarian cancer risk were calculated using logistic regression (NHS/NHS II; n = 217 cases) or Cox proportional hazards regression (WHS; n = 159 cases). Study-specific results were combined using random-effects meta-analysis. In the NHS/NHS II and WHS, we observed a 53% increased risk of invasive ovarian cancer when comparing women in the fourth quartile of CRP with women in the first quartile (95% confidence interval (CI): 1.05, 2.23). A CRP level of >10 mg/L versus a level of ≤1 mg/L was associated with a 2.16-fold increased risk (95% CI: 1.23, 3.78). In a meta-analysis of published studies, women in the third tertile of CRP had a 35% increased risk (95% CI: 1.10, 1.67) compared with women in the first tertile. There were no significant associations between interleukin 6 or tumor necrosis factor α receptor 2 and risk in the NHS/NHS II. Our results support the hypothesis that higher levels of circulating CRP are associated with increased risk of ovarian cancer, indicating that the role of inflammation in ovarian cancer requires further elucidation.

    Psoriasis has been shown to accompany systemic inflammation. We aimed to examine serum C-reactive protein (CRP) levels in Japanese psoriatic patients, and to elucidate their long-term as well as short-term changes by treatment with different biologics. A retrospective study was conducted in those who initiated and successfully continued the treatment for up to 24 months with either infliximab, adalimumab or ustekinumab, at the psoriasis special clinic of Jikei University School of Medicine. A total of 212 patients were included, 171 with plaque-type psoriasis (PsV) and 41 with psoriatic arthritis (PsA). A statistically significant elevation of CRP values was found in the group with a Psoriasis Area and Severity Index (PASI) of 12 or more compared with the PASI of less than 12 for both PsV and PsA. The CRP-positive patients had a higher proportion of PsA compared with the CRP-negative patients, and they had significantly higher PASI scores. Serum CRP values declined as early as at 3 months after systemic treatment with biologics. Tumor necrosis factor (TNF)-α antagonists did lead to a notable and sustained CRP decline up to 24 months. Infliximab showed rapid decline, while CRP decline by adalimumab treatment was time-dependent. The interleukin-12/23 p40 antagonist, ustekinumab, appeared to be less potent than TNF-α antagonists in stabilizing CRP values at low levels despite good control of cutaneous lesions. In conclusion, serum CRP levels can be used to assess disease severity in Japanese psoriatic patients as a marker of systemic inflammation. TNF-α antagonists may be more beneficial than ustekinumab in this regard. PMID:26704718

    Growing evidence shows interrelations of psychological factors, neurological and immunological processes. Therefore, constructs like a balance of activities, the so called "occupational balance", could also have biological correlates. The aim of this study was to investigate potential associations between occupational balance, functioning, cytokines and C-reactive protein (CRP) in patients suffering from a chronic inflammatory disease like rheumatoid arthritis (RA) and healthy people. Moreover, we wanted to explore potential differences in gender and employment status. A descriptive study in patients with RA and healthy people was conducted using the Occupational Balance-Questionnaire (OB-Quest) and the Short-Form 36 Health Survey (SF-36). Serum levels of cytokines, such as interleukin 6 (IL-6) and 8 (IL-8), interferon alpha (INFα), tumour necrosis factor alpha (TNFα), rheumatoid factor (RF) and of CRP were measured. Descriptive statistics, as well as Mann-Whitney U tests and Spearmen's rank correlation coefficients (rs) were calculated. One-hundred-thirty-two patients with RA and 76 healthy people participated. Occupational balance was associated with functioning, cytokines and CRP. The strongest associations were identified in the unemployed healthy-people sample with cytokines and CRP being within the normal range. For example, the OB-Quest item challenging activities was associated with IL-8 (rs=-0.63, p=0.04) and the SF-36 sub-scale bodily pain was associated with IFNα (rs=-0.69, p=0.02). The items rest and sleep (rs=-0.71, p=0.01) and variety of different activities (rs=-0.74, pconcepts encompassed in the construct of occupational balance were associated with functioning, cytokines and CRP.

    Full Text Available Abstract Background Metabolic syndrome (MetS is associated with an increased risk of major cardiovascular events. Increased high-sensitivity C-reactive protein (hsCRP levels are associated with MetS and its components. Changes in gamma-glutamyl transferase (GGT levels in response to oxidative stress are also associated with MetS, and the levels could be modulated by hsCRP. Methods From a single community, we recruited 822 men (mean age, 61 ± 14 years and 1,097 women (63 ± 12 years during their annual health examination. We investigated whether increased hsCRP and GGT levels are synergistically associated with MetS and insulin resistance evaluated by Homeostasis of model assessment of insulin resistance (HOMA-IR. Results Of these subjects, 141 men (17.2% and 170 women (15.5% had MetS. Participants with MetS had a higher hsCRP and GGT level than those without MetS in both genders, and the HOMA-IR increased significantly in correlation with an increase in hsCRP and GGT. In men, the adjusted odds ratios (95% confidence interval for MetS across tertiles of hsCRP and GGT were 1.00, 1.69 (1.01-2.80, and 2.13 (1.29-3.52, and 1.00, 3.26 (1.84-5.78 and 6.11 (3.30-11.3, respectively. In women, the respective corresponding values were 1.00, 1.54 (0.92-2.60, and 3.08 (1.88-5.06, and 1.00, 1.70 (1.04-2.79 and 2.67 (1.66-4.30. The interaction between increased hsCRP and GGT was a significant and independent determinant for MetS and insulin resistance in both genders. Conclusions These results suggested that higher CRP and GGT levels were synergistically associated with MetS and insulin resistance, independently of other confounding factor in the general population.

    Full Text Available Introduction. Elevated levels of oxidized LDL cholesterol (OxLDL are considered to be a key factor of initiating and accelerating atherosclerosis. It promotes atherosclerosis through inflammatory and immunologic mechanisms that lead to the formation of macrophage foam cells. Objective. To determine the relationship among OxLDL, C-reactive protein (CRP level and carotid intima-media thickness (IMT in population with risk factors for atherosclerosis. Methods. The study group consisted of 125 clinically healthy, hypercholesterolaemic subjects (49.3±5.7 years; 75 females and 50 males compared with 100 age-matched population-based control subjects. The study group was divided into two subgroups: subgroup A (the levels of LDL cholesterol > 5 mmol/L and subgroup B (the levels of LDL cholesterol <5 mmol/L. None of the subjects had history of cerebrovascular, ischaemic heart disease, hypertension or diabetes mellitus. Lipid profiles were measured by enzymatic methods. OxLDL was measured by using a specific monoclonal antibody, mAb4E6. CRP was measured using hemiluminescent methods (Immulite - DPC. The common carotid IMT was measured by the B-mode ultrasound. Results Compared to controls, the study group had higher levels of OxLDL (119.97±43.15 vs. 82.03±25.99 IU/L; p<0.01 and CRP (6.20±3.55 vs. 2.68±3.04 mg/ml; p<0.05. IMT was significantly higher in study subjects (1.14±0.38 vs. 0.72±0.24 mm; p<0.05. We also found that, in the whole study group, IMT significantly positively correlated with OxLDL (r=0.442; p<0.05. We found that in the study subgroup A, IMT positively correlated with CRP (r=0.792; p<0.01. In controls, we found a significantly positive association between IMT and OxLDL (r=0.781; p<0.01 and CRP (r=0.748; p<0.01. Conclusion. The elevated levels of OxLDL and CRP are associated with higher common carotid intima-media thickness in population with risk factors for atherosclerosis.

    Full Text Available Background Nowadays, clinical practice shows that the number of patients with cerebral infarction increases year by year in young and middle-aged adults with unclear causes. This paper aims to investigate the correlation between the level of serum uric acid (UA, high-sensitivity C-reactive protein (hsCRP and the degree of carotid atherosclerosis by detecting the level of UA, hsCRP and carotid intima-media thickness (IMT in young and middle-aged patients with lacunar infarct. Methods By using Holland Philips HT-11 color Doppler ultrasonic diagnostic apparatus with linear type probe and 7.50MHz frequency, IMT of end-diastolic distal and bifurcation of arteria carotis communis and proximal internal carotid artery were measured respectively on 186 patients with definitely diagnosed lacunar infarct. As a result, average values were taken as the IMT values. IMT < 1.00 mm was regarded as negative result and 1.00 mm ≤IMT < 1.20 mm was thickening of carotid artery intima. Carotid artery plaque formation was regarded with echo structure existing in the lumen or abnormal blood flow deficits into the lumen, or local IMT ≥1.20 mm at vertical and horizontal scan. At the same time, the levels of UA and hsCRP were detected, and correlation analysis was made between them and IMT. Results The values of UA, hsCRP and IMT in the case group were higher than that in the control group (P = 0.000. The differences among the case subgroups including IMT thickening group, plaque formation group and IMT normal group were statistically significant (P < 0.01, for all. There was linear correlation between the levels of UA, hsCRP and IMT ( r = 0.923, P = 0.000; r = 0.955, P = 0.008. Conclusion UA and hsCRP involve in the formation of atherosclerosis plaque and play an important role in the first-onset lacunar infarct patients without hypertension and other risk factors.

    Full Text Available INTRODUCTION: C-reactive protein (CRP levels are associated with cardiovascular disease and systemic inflammation. We assessed whether CRP-associated loci were associated with serum CRP and retinal markers of microvascular disease, in Asian populations. METHODS: Genome-wide association analysis (GWAS for serum CRP was performed in East-Asian Chinese (N = 2,434 and Malays (N = 2,542 and South-Asian Indians (N = 2,538 from Singapore. Leveraging on GWAS data, we assessed, in silico, association levels among the Singaporean datasets for 22 recently identified CRP-associated loci. At loci where directional inconsistencies were observed, quantification of inter-ethnic linkage disequilibrium (LD difference was determined. Next, we assessed association for a variant at CRP and retinal vessel traits [central retinal artery equivalent (CRAE and central retinal vein equivalent (CRVE] in a total of 24,132 subjects of East-Asian, South-Asian and European ancestry. RESULTS: Serum CRP was associated with SNPs in/near APOE, CRP, HNF1A and LEPR (p-values ≤4.7×10(-8 after meta-analysis of Singaporean populations. Using a candidate-SNP approach, we further replicated SNPs at 4 additional loci that had been recently identified to be associated with serum CRP (IL6R, GCKR, IL6 and IL1F10 (p-values ≤0.009, in the Singaporean datasets. SNPs from these 8 loci explained 4.05% of variance in serum CRP. Two SNPs (rs2847281 and rs6901250 were detected to be significant (p-value ≤0.036 but with opposite effect directions in the Singaporean populations as compared to original European studies. At these loci we did not detect significant inter-population LD differences. We further did not observe a significant association between CRP variant and CRVE or CRAE levels after meta-analysis of all Singaporean and European datasets (p-value >0.058. CONCLUSIONS: Common variants associated with serum CRP, first detected in primarily European studies, are also

    Cardiovascular disease (CVD) remains one of the leading causes of death and disability in developed countries around the world despite the documented success of lifestyle and pharmacological interventions. This illustrates the multifactorial nature of atherosclerosis and the use of novel inflammatory markers as an adjunct to risk factor reduction strategies. As evidence continues to accumulate that inflammation is involved in all stages of the development and progression of atherosclerosis, markers of inflammation such as high-sensitivity C-reactive protein (CRP) may provide additional information regarding the biological status of the atherosclerotic lesion. Recent investigations suggest that physical activity reduces CRP levels. Higher levels of physical activity and cardiorespiratory fitness are consistently associated with 6-35% lower CRP levels. Longitudinal training studies that have demonstrated reductions in CRP concentrations range from 16% to 41%, an effect that may be independent of baseline levels of CRP, body composition or weight loss. The average change in CRP associated with physical activity appears to be at least as good, if not better, than currently prescribed pharmacological interventions in similar populations. The primary purpose of this review will be to present evidence from both cross-sectional and longitudinal investigations that physical activity lowers CRP levels in a dose-response manner. Finally, this review will examine factors such as body composition, sex, blood sample timing, diet and smoking, which may influence the CRP response to physical activity. PMID:16646631

    C-reactive protein (CRP) is secreted by hepatocytes as a pentameric molecule made up of identical monomers, circulates in the plasma as pentamers, and localizes in atherosclerotic lesions. In some cases, localized CRP was detected by using monoclonal antibodies that did not react with native pentameric CRP but were specific for isolated monomeric CRP. It has been reported that, once CRP is bound to certain ligands, the pentameric structure of CRP is altered so that it can dissociate into mono...

  5. Impact of C-reactive protein (CRP) on surfactant function

    International Nuclear Information System (INIS)

    Plasma levels of the acute-phase reactant, C-reactive protein (CRP), increase up to one thousand-fold as a result of trauma or inflammation. CRP binds to phosphorylcholine (PC) in a calcium-ion dependent manner. The structural homology between PC and the major phospholipid component of surfactant, dipalmitoyl phosphatidylcholine (DPPC), led to the present study in which we examined if CRP levels might be increased in patients with adult respiratory distress syndrome (ARDS), and subsequently interfere with surfactant function. Our results showed that CRP levels in the bronchoalveolar fluid (BALF) was increased in patients with ARDS (97.8 +/- 84.2 micrograms/mg total protein vs. 4.04 +/- 2.2 micrograms/mg total protein in normals). Our results show that CRP binds to liposomes containing DPPC and phosphatidylglycerol (PG). As a result of this interaction, CRP inhibits the surface activity of a PG-DPPC mixture when tested with a Wilhelmy surfactometer or with the Enhorning pulsating bubble apparatus. Furthermore, the surface activity of a clinically used surfactant replacement, Surfactant TA (2 mg/ml), was also severely impaired by CRP in a dose-dependent manner (doses used ranging from 24.5 to 1,175 micrograms/ml). In contrast, human serum albumin (HSA) at 500 and 900 micrograms/ml had no inhibitory effect on Surfactant TA surface activity. These results suggest that CRP, although not an initiating insult in ARDS, may contribute to the subsequent abnormalities of surfactant function and thus the pathogenesis of the pulmonary dysfunction seen in ARDS

    Being the most common cause of death from poisoning worldwide, cardiovascular manifestations of acute carbon monoxide (CO) poisoning have been subject of various studies but current evidence about effects of chronic CO exposure on atherosclerosis is limited which is very common. We aimed to investigate association of chronic CO exposure with atherosclerosis by measuring carotid intima-media thickness (CIMT) and high-sensitivity C-reactive protein (hs-CRP). Forty healthy male non-smoker indoor barbecue workers (mean age; 33.0 +/- 9.0 years) working in different restaurants for at least three years and 48 age-matched healthy men (mean age; 34.3 +/- 6.6 years) enrolled in the study. Clinical characteristics of indoor barbecue workers and control group were comparable in terms of body mass index, blood pressure, and lipid profile. However, carboxyhemoglobin (COHb) (6.4 +/- 1.5% vs. 2.0 +/- 1.1%), hs-CRP (2.7 +/- 2.0 mg/L vs. 1.1 +/- 0.8 mg/L) and CIMT (1.1 +/- 0.3 mm vs. 0.9 +/- 0.1 mm) were higher in indoor barbecue workers (p independent predictor of CIMT (beta = 0.571, p < 0.001). The increased CIMT and hs-CRP in indoor barbecue workers suggest that chronic CO exposure may increase the risk of atherosclerotic cardiovascular events. PMID:19851048

    Full Text Available BACKGROUND: High-sensitivity C-reactive protein predicts cardiovascular events in a wide range of clinical contexts. However, the role of high-sensitivity C-reactive protein as a predictive marker for perioperative acute myocardial infarction during noncardiac surgery is not yet clear. The present study investigated high-sensitivity C-reactive protein levels as predictors of acute myocardial infarction risk in patients undergoing high-risk noncardiac surgery. METHODS: This concurrent cohort study included patients aged >50 years referred for high-risk noncardiac surgery according to American Heart Association/ACC 2002 criteria. Patients with infections were excluded. Electrocardiograms were performed, and biomarkers (Troponin I or T and/or total creatine phosphokinase and the MB fraction (CPK-T/MB were evaluated on the first and fourth days after surgery. Patients were followed until discharge. Baseline high-sensitivity C-reactive protein levels were compared between patients with and without acute myocardial infarction. RESULTS: A total of 101 patients undergoing noncardiac surgery, including 33 vascular procedures (17 aortic and 16 peripheral artery revascularizations, were studied. Sixty of the patients were men, and their mean age was 66 years. Baseline levels of high-sensitivity C-reactive protein were higher in the group with perioperative acute myocardial infarction than in the group with non-acute myocardial infarction patients (mean 48.02 vs. 4.50, p = 0.005. All five acute myocardial infarction cases occurred in vascular surgery patients with high CRP levels. CONCLUSIONS: Patients undergoing high-risk noncardiac surgery, especially vascular surgery, and presenting elevated baseline high-sensitivity C-reactive protein levels are at increased risk for perioperative acute myocardial infarction.

    Full Text Available Psychological depression is an independent risk factor for coronary artery disease. C-reactive protein has been implicated as a mediator of the effect of psychological depression. Several studies have found that individuals, especially men, who report higher levels of psychological depression also have higher levels of C-reactive protein. The current study was undertaken to replicate these results in a Brazilian population, in which there is a much wider range of variation in both background characteristics (such as socioeconomic status and coronary artery disease risk factors. A sample of 271 individuals was interviewed using the Center for Epidemiological Studies Depression Scale. Fasting blood samples were obtained and evaluated for C-reactive protein (assessed by a turbidimetric immunoassay using a Dade Behring kit analysis in a subsample (N = 258 of individuals. The mean ± SD C-reactive protein for the entire sample was 0.43 ± 0.44, with 0.42 ± 0.48 for men and 0.43 ± 0.42 mg/L for women. Data were analyzed using multiple regression analysis, controlling for age, sex, body mass index, socioeconomic status, tobacco use, and both total cholesterol and low-density lipoprotein cholesterol. Higher reported depressive symptoms were correlated with higher C-reactive protein for men (partial r = 0.298, P = 0.004 and with lower C-reactive protein for women (partial r = -0.154, P = 0.059. The differences in the associations for men and women could be a result of differential effects of sex hormones on stress reactivity and immune response. On the other hand, this difference in the associations may be related to gender differences in the disclosure of emotion and the effect that self-disclosure has on physical health and immune response.

    Atrial fibrillation is associated with substantial morbidity and mortality rates. The incompletely understood pathogenesis of this cardiac dysrhythmia makes it difficult to improve approaches to primary and secondary prevention. Evidence has accumulated in regard to a relationship between inflammation and atrial fibrillation. Investigators have correlated the dysrhythmia with myocarditis, pericardiotomy, and C-reactive protein levels, suggesting that inflammation causes atrial fibrillation or...

    Full Text Available : Ischemic stroke is the 3rd leading cause of death after AMI and cancer. Stroke is also the leading cause of hospital admission causing disability. The study was based on 100 patients with ischemic stroke admitted to the JJM Medical College, Davangere. This study was done to estimate the role of C-reactive protein as a marker of acute inflammation following ischemic stroke and also to determine, its prognostic role, by assessing the functional outcome of patient using modified Barthel index scoring (ADL. Patients with CRP 6 mg/dl suffered severe disease with poor functional outcome. P value <0.05, significant, suggests CRP is a good tool for prognostic indicator

  3. Capacitive immunosensor for C-reactive protein quantification

    KAUST Repository

    Sapsanis, Christos

    2015-08-02

    We report an agglutination-based immunosensor for the quantification of C-reactive protein (CRP). The developed immunoassay sensor requires approximately 15 minutes of assay time per sample and provides a sensitivity of 0.5 mg/L. We have measured the capacitance of interdigitated electrodes (IDEs) and quantified the concentration of added analyte. The proposed method is a label free detection method and hence provides rapid measurement preferable in diagnostics. We have so far been able to quantify the concentration to as low as 0.5 mg/L and as high as 10 mg/L. By quantifying CRP in serum, we can assess whether patients are prone to cardiac diseases and monitor the risk associated with such diseases. The sensor is a simple low cost structure and it can be a promising device for rapid and sensitive detection of disease markers at the point-of-care stage.

  4. Production of C-reactive protein by human lymphocytes

    International Nuclear Information System (INIS)

    C-reactive protein (CRP) is a major acute phase serum protein in humans; it is detectable at very high concentrations during infection and tissue trauma. This protein is a pentame composed of five identical, 21,500 MW subunits. CRP is detectable on the surface of approximately 4% of normal peripheral blood lymphocytes (PBL). CRP binds its physiological ligands in a Ca++ dependent manner; removal of Ca++ does not alter the expression of CRP on the lymphocyte surface. Recently, investigators in this laboratory reported substantial inhibition of natural killer cell (NK) activity with anti-CRP antibodies. The following studies were undertaken to determine the origin of surface-CRP (S-CRP) found on normal PBL. Cells were incubated in methionine-free DMEM supplemented with 35S-methionine. Cells were lysed and subjected to immunoprecipitation with anti-CRP and Staphylococcus aureus; immunoprecipitates were analyzed by SDS-PAGE and autoradiography. Data presented here suggested that lymphocytes, in particular, LGL produce small amounts of CRP and express it on their surface. Lymphocytes do not appear to secrete CRP since no CRP could be detected in culture supernatants. In addition, preliminary evidence indicates that peripheral blood monocytes produce no detectable CRP. Present studies utilizing Northern blot analysis are underway in order to detect CRP-mRNA

Acute-phase proteins and cytokines were measured by ELISA in 24 healthy pregnant women undergoing vaginal delivery or Cesarean section. Cord blood samples in addition to maternal blood were collected. SAA and CRP reached the maximum maternal serum levels 24 hours after delivery, while cytokines remained constant over time. SAA and CRP were significantly higher in maternal serum than in newborn's (P<.001 at the moment of delivery. SAA and CRP, regardless of the type of delivery, reproduce the common pattern observed in most inflammatory conditions. Proinflammatory cytokine serum levels do not mirror the increase in SAA and CRP levels.

    Inflammation of vascular cell wall is the key problem and proinflammatory cytokines and chemokines play a great role in it. These molecules, togheter with C-reactive protein (CRP) can predict risk of coronary events. It is questionable to what extend are CRP and pro-inflammatory cytokines purely acute phase markers and to what extend are they active inflammatory participants. Besides inflammation, other prominent mechanism in the pathogenesis of atherosclerosis and atherothrombosis--underlying causes of coronary events, is genetics. Gene polymorphisms including polymorphisms of inflammatory markers are studied and one of them, polymorphism of monocyte chemoattractant protein (MCP-1/CCL2) and its receptor CCR2 (key components of atherosclerosis) belong to most studied one. MCP-1/CCL2 and CCR2 polymorphisms have been implicated as susceptibility factors for chronic stable angina pectoris and myocardial infarction by several independent investigators. It seems that CCL2/CCR2 axis plays an important role both in post-ischemic and post-reperfusion inflammation and could become a new therapeutic goal in selected cardiovascular diseases as well as in stroke in future. Inhibition of this axis disrupts ischemic-reperfusion injury by decreasing edema, leucocyte infiltration and expression of inflammatory mediators. One can suppose that identifying genes influencing inflammatory biomarkers might improve understanding of genetic determinants of cardiovascular disease our management and prevention (Tab. 2, Fig. 1, Ref. 105).

    Background The present clinical trial study was designed to assess the effect of topical application of melatonin on serum levels of tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6) and C-reactive protein (CRP) in patients with diabetes and periodontal disease in comparison with healthy controls. Material and Methods Serum levels of TNF-α and IL-6 were measured by enzyme-linked immunosorbent assay and CRP by nephelometry by using the proper commercial kits in 30 patients with diabetes and periodontal disease, and also in a control group of 30 healthy subjects. Periodontograms were performed using the Florida Probe®. Patients with diabetes were treated with a topical application of melatonin (1% orabase cream formula) once daily for 20 days. Healthy subjects were treated with a placebo orabase cream. Results Patients with diabetes and periodontal disease had significantly higher mean levels of serum TNF-α, IL-6 and CRP than healthy subjects (P < 0.001). Following topical melatonin application, there was a statistically significant decrease in the gingival index and pocket depth (P < 0.001) as well as a significant decrease in IL-6 and CRP serum levels (P < 0.001). Local melatonin application in patients with diabetes and periodontal disease resulted in a significant decrease in CRP and IL-6 serum levels as well as an improvement in the gingival index and pocket depth. Patients with periodontal disease had significantly higher serum CRP, IL-6 and TNF-α values by comparison with healthy subjects. Conclusions We conclude that melatonin can modulate the inflammatory action of these molecules in periodontal patients.

    The serum levels of C-reactive protein on admission may predict the efficacy of reperfusion in patients with acute myocardial infarction. Objectives: This study was conducted to know the predictive value of CRP for success of thrombolysis and to know the prognostic value of C-reactive protein in patients having acute myocardial infarction. Study Design: It was single center, open labeled cross sectional study. Materials and Methods: Sixty patients of acute myocardial infarction diagnosed on clinical and ECG criteria, who received thrombolytic therapy with strepto- kinase, were included in the study. The diagnosis of acute rnyocardial infarction was made on clinical para meters and ECG criteria. The ECG changes were noted before starting thrombolysis. The baseline sample for C-reactive protein (CRP,) was taken before starting thrombolysis. The time duration between onset of symptoms and start of thrombolysis was also noted. The thrombolysis was done with streptokinase infusion, 1.5 million units diluted in 100ml normal saline, intravenously over one hour. The ECG was repeated after six hours of completion of thrombolysis and, changes were noted and compared with ECG changes before thrombolysis. Now second sample for C-reactive protein (CRP2) was taken after six hours of completion of thrombolysis. CRP was measured by a high sensitivity assay which can accurately measure basal levels of CRP throughout the currently accepted cardiovascular risk assessment range (0.20 - 10.0 mg/L). According to ECG findings after thrombolysis, all patients were divided into two groups. Group A was considered as successful group to thrombolysis, in whom ECG changes were settled. Group B was considered as unsuccessful group to thrombolysis, in whom ECG changes remained same as before thrombolysis. Both values of C-reactive protein, CRP, and CRP2 were compared in both groups group A and group B. Results: Plasma CRP values before and after thrombolysis had strong predictive value for

    Full Text Available Vitamin D deficiency is widely prevalent and has been associated with many diseases. It has been suggested that vitamin D has effects on the immune system and inhibits inflammation. The aim of our study was to investigate whether vitamin D has an inhibitory effect on systemic inflammation by assessing the association between serum levels of vitamin D and C-reactive protein. We studied the association between serum 25-hydroxyvitamin D and C-reactive protein through linear regression in 9,649 participants of the Rotterdam Study, an observational, prospective population-based cohort study. We used genetic variants related to vitamin D and CRP to compute a genetic risk score and perform bi-directional Mendelian randomization analysis. In linear regression adjusted for age, sex, cohort and other confounders, natural log-transformed CRP decreased with 0.06 (95% CI: -0.08, -0.03 unit per standard deviation increase in 25-hydroxyvitamin D. Bi-directional Mendelian randomization analyses showed no association between the vitamin D genetic risk score and lnCRP (Beta per SD = -0.018; p = 0.082 or the CRP genetic risk score and 25-hydroxyvitamin D (Beta per SD = 0.001; p = 0.998. In conclusion, higher levels of Vitamin D are associated with lower levels of C-reactive protein. In this study we did not find evidence for this to be the result of a causal relationship.

Methods: Serum levels of the above four parameters and the positive rate of the two antibodies were measured (with CLIA, ELISA and RIA as appropriately) in 184 patients with type 2 diabetes and 30 controls as well as in 75 patients after one year of treatment. Results: The serum contents of insulin, leptin, CRP, insulin antibody in patients with type 2 diabetes were significantly higher (P<0.01) and APN levels significantly lower (P<0.001) than those in controls. Levels of APN were negatively correlated with those of the other parameters. In the 75 treated patients, levels of those parameters (with the exception of APN and insulin-antibody) decreased significantly. However, the APN levels were significantly increased (vs before treatment, P<0.001). Conclusion: Further study on the dynamic changes of these parameters in the diabetic patients might elucidate certain key-points in the pathogenesis of the disease. (authors)

    Full Text Available While the risk of TB is elevated in HIV-positive subjects with low CD4 cell counts, TB may in itself be associated with CD4 lymphocytopenia. We investigated markers of immune activation (neopterin and inflammation (CRP in TB patients with and without HIV coinfection and their association with CD4 cell levels, and determined their predictive capacity as alternative markers of advanced immunosuppression.Participants selected from a cohort of adults with TB at Ethiopian health centers (195 HIV+/TB+, 170 HIV-/TB+ and 31 controls were tested for plasma levels of neopterin and CRP. Baseline levels of neopterin and CRP were correlated to CD4 cell count before and after anti-TB treatment (ATT. The performance to predict CD4 cell strata for both markers were investigated using receiver operating curves.Levels of both biomarkers were elevated in TB patients (neopterin: HIV+/TB+ 54 nmol/l, HIV-/TB+ 23 nmol/l, controls 3.8 nmol/l; CRP: HIV+/TB+ 36 μg/ml, HIV-/TB+ 33 μg/ml, controls 0.5 μg/ml. Neopterin levels were inversely correlated (-0.53, p<0.001 to CD4 cell count, whereas this correlation was weaker for CRP (-0.25, p<0.001. Neither of the markers had adequate predictive value for identification of subjects with CD4 cell count <100 cells/mm3 (area under the curve [AUC] 0.64 for neopterin, AUC 0.59 for CRP.Neopterin levels were high in adults with TB, both with and without HIV coinfection, with inverse correlation to CD4 cell count. This suggests that immune activation may be involved in TB-related CD4 lymphocytopenia. However, neither neopterin nor CRP showed promise as alternative tests for immunosuppression in patients coinfected with HIV and TB.

    Full Text Available Context There is paucity of data on the prognostic value of pre-operative inflammatory res ponse and post-operative lymph node ratio on patient survival after pancreatic-head resection for pancreatic ductal adenocarcinoma. Objectives To evaluate the role of the preoperative inflammatory response and postope rative pathology criteria to identify pr edictive and/or prognostic variables for pancreatic ductal adenocarcinoma. Design All patients who underwent pancreatic oduodenectomy for pancreatic ductal adenocarcinoma between 2002 and 2008 we re reviewed retrospec tively. The following impacts on pa tient survival were assessed: i preoperative serum CRP levels, white ce ll count, neutrophil count, neutrophil/ly mphocyte ratio, lymphocyte count, platelet/lymphocyte ratio; and ii post-operative pathology criteria incl uding lymph node status and lymph node ratio. Results Fifty- one patients underwent potentially curative resection for pancreatic ductal adenocar cinoma during the study period. An elevated preoperative CRP level (greater than 3 mg/L was found to be a significant adverse prognostic factor (P=0.015 predicting a poo r survival, whereas white cell count (P=0.278, neutroph il count (P=0.850, neutrophil/lymphocyte ratio (P=0.272, platelet/lymphocyte ratio (P=0.532 and lym phocyte count (P=0.721 were not significant prognosticat ors at univariate analysis. Presence of metastatic lymph nodes did not adversely affect survival (P =0.050, however a raised lymph node ratio predicted poo r survival at univariate analysis (P<0.001. The preoperative se rum CRP level retained significance at multivariate analysis (P=0 .011, together with lymph node ratio (P<0.001 an d tumour size (greater than 2 cm; P=0.008. Conclusion A pre-operative elevated serum CRP level and raised post-operative lymph node ratio represen t significant independent prognostic factors that predict poor prognosis in patients undergoing curative rese ction for pancreatic ductal

    Full Text Available The increased incidence of coronary artery disease (CAD in Type 2 Diabetes mellitus is not fully explained by the conventional risk factors. Our aim was to determine the association of biomarkers, high sensitive CRP and anticardiolipin antibody (acL with severity of coronary artery disease in patients with and without type 2 DM. In our study, hsCRP level was significantly high in CAD with DM and found to be positively correlated with severity (p<0.01 while anticardiolipin antibody does not show any significant change among the two groups. Our study concluded that increased risk of CAD in type 2 DM patients is not only because of dyslipidemia but inflammatory events also play a major role. hsCRP was found to be a valuable predictor for CAD in type 2 DM.

    Full Text Available The pathogenesis of autism, a neurological disorder severely affecting young children, may involve inflammation and autoimmunity. In this report, the distribution of acute-phase C-reactive protein (CRP and S100 proteins was examined in normal and autistic children. Their serum levels were measured by enzyme-linked immunosorbent assay (ELISA. Autistic children were found to have significantly higher than normal levels of CRP (p=0.005 and S100 proteins (p=0.03. The existence of elevated levels of CRP and S100 proteins in autistic children is an excellent sign of systemic inflammation that may contribute to the neuropathology of this brain disorder.

    C-reactive protein (CRP) has been linked to the pathogenesis of atherosclerosis. The dissociation of native, pentameric (p)CRP to monomeric (m)CRP on the cell membrane of activated platelets has recently been demonstrated. The dissociation of pCRP to mCRP may explain local pro-inflammatory reactions at the site of developing atherosclerotic plaques. As a biomarker, pCRP predicts cardiovascular adverse events and so do reduced levels and function of circulating endothelial progenitor cells (EP...

    Full Text Available Abstract Background The purpose of this study was to explore the diagnostic value of soluble triggering receptor expressed on myeloid cells 1 (sTREM-1, procalcitonin (PCT, and C-reactive protein (CRP serum levels for differentiating sepsis from SIRS, identifying new fever caused by bacteremia, and assessing prognosis when new fever occurred. Methods We enrolled 144 intensive care unit (ICU patients: 60 with systemic inflammatory response syndrome (SIRS and 84 with sepsis complicated by new fever at more than 48 h after ICU admission. Serum sTREM-1, PCT, and CRP levels were measured on the day of admission and at the occurrence of new fever (>38.3°C during hospitalization. Based on the blood culture results, the patients were divided into a blood culture-positive bacteremia group (33 patients and blood culture-negative group (51 patients. Based on 28-day survival, all patients, both blood culture-positive and -negative, were further divided into survivor and nonsurvivor groups. Results On ICU day 1, the sepsis group had higher serum sTREM-1, PCT, and CRP levels compared with the SIRS group (P P Conclusions Serum sTREM-1, PCT, and CRP levels each have a role in the early diagnosis of sepsis. Serum sTREM-1, with the highest sensitivity and specificity of all indicators studied, is especially notable. sTREM-1, PCT, and CRP levels are of no use in determining new fever caused by bacteremia in ICU patients, but sTREM-1 levels reflect the prognosis of bacteremia.

    Full Text Available Abstract Background Coronary artery disease (CAD is a major vascular complication of diabetes mellitus and reveals high mortality. Up to 30% of diabetic patients with myocardial ischemia remain asymptomatic and are associated with worse prognosis compared to non-diabetic counterpart, which warrants routine screening for CAD in diabetic population. The purpose of this study was to evaluate the clinical value of serum glycated albumin and high-sensitivity C-reactive protein (hs-CRP levels in predicting the presence of CAD in patients with type 2 diabetes. Methods Three hundred and twenty-four patients with type 2 diabetes were divided into two groups based on presence (CAD group, n = 241 or absence (control group, n = 83 of angiographically-documented CAD (lumen diameter narrowing ≥70%. Serum levels of glycated albumin and hs-CRP as well as serum concentrations of glucose, lipids, creatinine, blood urea nitrogen and uric acid were measured in both groups. Predictors of CAD were determined using multivariate logistic regression model and receiver-operating characteristic (ROC curves. Results Serum glycated albumin and hs-CRP levels were significantly increased in diabetic patients with CAD. Multivariate regression analysis revealed that male gender, age, serum levels of glycated albumin, hs-CRP, creatinine and lipoprotein (a were independent predictors for CAD. Areas under the curve of glycated albumin and hs-CRP and for regression model were 0.654 (95%CI 0.579–0.730, P Conclusion Serum glycated albumin and hs-CRP levels were significantly elevated in patients with type 2 diabetes and CAD. The logistic regression model incorporating with glycated albumin, hs-CRP and other major risk factors of atherosclerosis may be useful for screening CAD in patients with type 2 diabetes.

    Full Text Available The prevalence of obesity and sarcopenia is high among the elderly. The simultaneous occurrence of these two disorders results in sarcopenic obesity. Research suggests that inflammation has an important role in the pathogenesis of obesity and sarcopenia. This study explores the impact of sarcopenic obesity on inflammatory markers, including interleukin-6 (IL-6, high-sensitivity C-reactive protein (hs-CRP, and tumor necrosis factor-alpha (TNF-α. This study is a community-based cross-sectional study. The study sample consisted of 844 community-dwelling people aged 65 years and older (448 men and 396 women. Sarcopenia was characterized by low muscle mass (skeletal muscle index < 6.87 and 5.46 kg/m2 for men and women, respectively, and obesity was characterized by excess body fat (body fat percentage greater than the 60th percentile of the study sample by sex [27.82% in men and 37.61% in women]. Older individuals identified with sarcopenic obesity were those who had both sarcopenia and obesity. Inflammatory markers such as IL-6, hs-CRP, and TNF-α were measured. The prevalence rates of obesity only, sarcopenia only, and sarcopenic obesity were 32.94%, 11.85%, and 7.23%, respectively. No difference was observed in the serum levels of IL-6 and TNF-α among the four groups of combined sarcopenia and obesity status. After multivariate adjustment, the serum hs-CRP levels in the obesity only and in the sarcopenic obesity groups were 0.14 and 0.16 mg/dL among males, respectively, which were significantly higher than that in the normal group (P=0.012 and 0.036. Our results provide evidence that obesity and sarcopenic obesity are associated with increased levels of serum hs-CRP among males.

    International Nuclear Information System (INIS)

    C-reactive protein (CRP) is an acute phase protein. It predicts future risk of cardiovascular diseases. Different medicinal plants and their active ingredients possess the ability to reduce serum CRP levels and hence inflammatory disorders and cardiovascular diseases. In our study, ethanolic extract of Nigella sativa seeds was evaluated in albino rats for its possible effect on serum CRP levels. Objective: The objective of this study was to determine the effect of ethanolic extract of Nigella sativa seeds on an acute inflammatory biomarker/mediator, C-reactive protein (CRP) in albino rats. Study Design: Randomized controlled trial (RCT). Place and Duration of Study: Physiology Department, Services Institute of Medical Sciences (SIMS), Lahore; from September to November, 2009. Subjects and Methods: The study was carried out on 90 male albino rats. Five percent (5%) formalin in a dose of 50 meu1 was injected into sub-plantar surface of right hind paw of each rat to produce inflammation. The rats were randomly divided into three groups of thirty each. Group A was given normal saline (control); group B was given Nigella sativa seed extract; and group C received diclofenac sodium, as a reference drug. CRP levels in each group were measured from blood samples taken 25 hours after giving formalin. Results: The ethanolic extract of Nigella sativa seeds, given intraperitoneally, caused highly significant (p<0.001) reduction in serum CRP levels as compared to control group. The reduction in CRP levels by ethanolic extract of Nigella sativa was also significantly (p<0.05) more than that produced by diclofenac sodium. Conclusion: Our results suggest that Nigella sativa possesses ability to reduce serum CRP levels significantly, after production of artificial inflammation, in albino rats. (author)

    Full Text Available C-reactive protein (CRP and coronary heart disease (CHD have been the subject of intensive investigations over the last decades. Epidemiological studies have shown an association between moderately elevated CRP levels and incident CHD whereas genetic studies have shown that polymorphisms associated with elevated CRP levels do not increase the risk of ischemic vascular disease, suggesting that CRP might be a bystander rather than a causal factor in the progress of atherosclerosis. Beside all those epidemiological and genetic studies, the experimental investigations also try to reveal the role of CRP in the progress of atherosclerosis. This review will highlight the complex results of genomic, epidemiological, and experimental studies on CRP and will show why further studies investigating the relationship between CRP and atherosclerosis might be needed.

    If surgical closure of chronic wounds is an option, choosing an appropriate time to definitely close these wounds remains a challenge. Although the underlying mechanisms of nonhealing are not completely understood, serum C-reactive protein (CRP) and interleukin-6 (IL-6) in wound fluid have been found to be markers of the systemic and local inflammation state of chronic wounds. The purpose of this prospective, descriptive pilot study was to evaluate the effect of debridement, systemic antibiotics, and negative pressure wound therapy (NPWT) on the outcomes of trauma-related chronic wounds and changes in local inflammation responses, measured using CRP and IL-6 levels as indicators of cytokine regulation. Between June 2012 and May 2013, 20 consecutive patients (14 men, six women, mean age 40 [range 17-56] years) with various trauma-related, nonhealing chronic wounds were enrolled in the study after failing to heal for an average of 8.5 (range 6-16) weeks using a protocol of regular debridement and gauze dressings. Before the start of the study, wounds were cultured, and laboratory values for white blood cell count (WBC), neutrophils, and levels of serum CRP and IL-6 in the wound fluid obtained. Wounds were surgically debrided and NPWT (continuous at 125 mm Hg) applied. All patients were prescribed systemic antibiotics, and mean time interval between NPWT dressing changes was 5 (range 3-7) days. During an average mean NPWT treatment time of 13 (range 5-20) days, CRP and IL-6 concentrations decreased from 66.4 mg/L to 10.4 mg/L and 44.1 pg/mL to 8.6 pg/mL, respectively (P <0.001). The presence/absence of bacteria, WBC, and neutrophil counts did not change. No complications were noted, and all wounds were successfully closed using various surgical procedures. In this study, clinical wound improvement and a significant decrease in wound fluid CRP and IL-6 levels were observed. Studies with a larger sample size and a more robust study design may help elucidate the

    Previous studies have shown that coronary plaque composition plays a pivotal role in plaque instability, and imaging modalities and serum biomarkers have been investigated to identify vulnerable plaque. Virtual histology IVUS (VH-IVUS) characterizes plaque components as calcified, fibrotic, fibrofatty, or necrotic core. C-reactive protein (hsCRP) is an independent risk factor and a powerful predictor of future coronary events. However, a relationship between inflammatory response indicated by CRP and plaque characteristics in ACS patients remains not well established. To determine, by using VH-IVUS, the relation between coronary plaque components and plasma high-sensitivity CRP levels in patients with acute coronary syndromes (ACS). 52 patients with ACS were enrolled in this prospective study. Electrocardiographically-gated VH-IVUS were performed in the culprit lesion before PCI. Blood sample was drawn from all patients before the procedure and after 24 hours, and hs-CRP levels were determined. Mean age was 55.3±4.9 years, 76.9% were men and 30.9% had diabetes. Mean MLA was 3.9±1.3 mm2, and plaque burden was 69±11.3%, as assessed by IVUS. VH-IVUS analysis at the minimum luminal site identified plaque components: fibrotic (59.6±15.8%), fibrofatty (7.6±8.2%), dense calcium (12.1±9.2%) and necrotic core (20.7±12.7%). Plasma hs-CRP (mean 16.02±18.07 mg/L) did not correlate with necrotic core (r=-0.089, p = 0.53) and other plaque components.

    This brief lifestyle intervention, including a vegan diet rich in fresh fruits and vegetables, whole grains and various legumes, nuts and seeds, significantly improved health risk factors and reduced systemic inflammation as measured by circulating CRP. The degree of improvement was associated with baseline CRP such that higher levels predicted greater decreases. The interaction between gender and baseline CRP was significant and showed that males with higher baseline CRP levels appeared to have a more robust decrease in CRP due to the intervention than did their female counterparts. It is likely that the vegetable and high fiber content of a vegan diet reduces CRP in the presences of obesity. Neither the quantity of exercise nor the length of stay was significant predictors of CRP reduction. Additionally, those participants who had a vegan diet prior to the intervention had the lowest CRP risk coming into the program. Direct measure of body fat composition, estrogen and other inflammatory mediators such as IL-6 and TNF-alpha would enhance current understanding of the specific mechanisms of CRP reduction related to lifestyle interventions.

    Full Text Available BACKGROUND Cerebrovascular ischemia is recognized as a major health problem, which causes significant morbidity and mortality. The main pathophysiology of ischemic stroke is atherosclerosis of cerebral vessels. Hs-CRP is a sensitive marker of inflammation tissue injury in the arterial wall, which contributes to atherosclerosis. In this study, we aim to investigate the association of hs-CRP in patients with ischemic stroke and to correlate hs-CRP levels with possible risk factors of ischemic stroke and to assess the prognostic value of hs-CRP in ischemic stroke. METHODS In the present case control study after meeting inclusion and exclusion criteria, 50 patients with acute ischemic stroke admitted in the medical ward, King George Hospital, during the period between April 2014 and October 2014 and 40 asymptomatic age and sex matched control subjects were included. RESULTS The mean hs-CRP value in cases is 3.78+5.28mg/dl and in controls is 0.425+0.305mg/dl. Mean hs-CRP value is higher (3.78mg/dl in cases when compared to controls (0.425mg/dl, which is statistically significant. P admitted with severe degree of weakness (0-1/5 power with mean hs-CRP value of 4.28+4.07 without significant improvement in the power at the time of discharge; 8(16%> with mean hs-CRP value of 10.43+7.74 were expired. CONCLUSION Acute ischemic patients had higher mean hs-CRP values when compared to healthy asymptomatic control subjects P0.05.

    Full Text Available Abstract Background C-reactive protein (CRP, a marker of sub-clinical inflammation, is a predictor of future cardiovascular diseases. Dietary habits affect serum CRP level however the relationship between consumption of individual food groups and CRP levels has not been established. Methods This study was designed to explore the relation between food intake and CRP levels in children using data from the cross-sectional 1999-2002 National Health and Nutrition Examination Surveys. CRP level was classified as low, average or high (3.0 mg/L, respectively. Adjusted mean daily intakes of dairy, grains, fruit, vegetables, and meat/other proteins in each CRP category were estimated using multivariate analysis of covariance modeling. The effect modification by age (5-11 years vs. 12-16 years, gender and race/ethnicity was explored. We examined whether total or central body fat (using BMI Z-scores and waist circumference explained any of the observed associations. Results A total of 4,010 children and adolescents had complete information on diet, CRP and all covariates of interest and were included in the analyses. Individuals with high CRP levels had significantly lower intake of grains (p Conclusion Children and adolescents with higher CRP levels had significantly lower intakes of grains and vegetables. The associations between selected childhood dietary patterns and CRP levels seem largely mediated through effects on body composition.

    Full Text Available Abstract C-Reactive Protein (CRP is an acute phase reactant routinely used as a biomarker to assess either infection or inflammatory processes such as autoimmune diseases. CRP also has demonstrated utility as a predictive marker of future risk of cardiovascular disease. A new method of immunoassay for the detection of C-Reactive Protein has been developed using Resonant Acoustic Profiling™ (RAP™ with comparable sensitivity to a high sensitivity CRP ELISA (hsCRP but with considerable time efficiency (12 minutes turnaround time to result. In one method, standard solutions of CRP (0 to 231 ng/mL or diluted spiked horse serum sample are injected through two sensor channels of a RAP™ biosensor. One contains a surface with sheep antibody to CRP, the other a control surface containing purified Sheep IgG. At the end of a 5-minute injection the initial rate of change in resonant frequency was proportional to CRP concentration. The initial rates of a second sandwich step of anti-CRP binding were also proportional to the sample CRP concentration and provided a more sensitive method for quantification of CRP. The lower limit of detection for the direct assay and the homogenous sandwich assay were both 20 ng/mL whereas for the direct sandwich assay the lower limit was 3 ng/mL. In a step towards a rapid clinical assay, diluted horse blood spiked with human CRP was passed over one sensor channel whilst a reference standard solution at the borderline cardiovascular risk level was passed over the other. A semi-quantities ratio was thus obtained indicative of sample CRP status. Overall, the present study revealed that CRP concentrations in serum that might be expected in both normal and pathological conditions can be detected in a time-efficient, label-free immunoassay with RAP™ detection technology with determined CRP concentrations in close agreement with those determined using a commercially available high sensitivity ELISA.

    Objective: To investigate the prognostic value of plasma C-reactive protein(CRP) level in patients with paraquat poisoning.Methods: This study included 162 patients with paraquat poisoning. The data of plasma paraquat, CRP level and arterial blood gas were analyzed. Cox regression analysis was applied to evaluate the risk factors of prognosis. Receiver operating characteristics curve analysis and area under curve were used to calculate the predictive power of significant variable. Differences in patient survival were determined using the Kaplan–Meier method and a log-rank test.Results: Plasma CRP level was significantly increased in non-survival patients compared with survival patients(P < 0.05), and positively correlated with plasma paraquat level(P < 0.05). Cox regression analysis revealed that plasma CRP level was an independent prognostic marker of mortality within 30 days. The receiver operating characteristics curve analysis indicated that area under curve of plasma CRP level was0.867(95% CI: 0.81–0.93), and the cut-off value was 18 mg/L, and patients with CRP level over this value had a poor survival time compared with those with less than this value.Conclusions: These results suggest that plasma CRP level is distinct increased in patients with paraquat poisoning, and the plasma CRP level may be useful for the prediction of prognosis in paraquat poisoning.

    Full Text Available OBJECTIVE: This study assessed the diagnostic performance and prognostic properties of C-reactive protein (CRP, copeptin and cortisol in individuals with sickle cell anaemia (SCA. DESIGN: Prospective case-control study. METHODS: Sixty consecutive SCA subjects (18-40 years comprising 30 subjects in the steady state and 30 subjects in vaso-occlusive crisis (VOC were recruited into this study. Thirty (30 apparently healthy individuals with HbAA genotype served as controls. ELISA was used for the determination of serum levels of copeptin, CRP and cortisol. Data obtained were statistically analyzed using the Student's t-test and Mann Whitney U as appropriate and P<0.05 was considered significant. RESULTS: SCA subjects in VOC had significantly lower copeptin level and significantly higher CRP level compared with controls. However, serum levels of copeptin, cortisol and CRP were significantly higher in SCA subjects in VOC compared with SCA subjects in steady state. Furthermore, CRP had the widest Area under the ROC curve (AUROC than copeptin and cortisol. No significant difference was observed in the levels of copeptin, CRP and cortisol when SCA subjects in VOC who were hospitalized for less ≤ 5 days were compared with subjects who had longer stays. CONCLUSION: It could be concluded that C-reactive protein has a superior diagnostic performance for vaso-occlusive crisis in individuals with sickle cell anaemia and that C-reactive protein, cortisol and copeptin are not good prognostic markers in SCA subjects in vaso-occlusive crisis.

    The C-reactive protein is a generally recognized marker of inflammation and bacterial infection. However, issue of diagnostic effectiveness of this indicator is still open-ended in case of patients with oncologic hematological diseases. The level of C-reactive protein can increase under neoplastic processes. On the contrary, the inhibition of immune response observed under cytoplastic therapy can decrease synthesis of this protein. The study was organized to establish levels of C-reactive protein as markers of infection in adult patients with acute lymphoblastic leucosis under application of chemotherapy and to evaluate their diagnostic effectiveness. The sampling included 34 patients with acute lymphoblastic leucosis all patients had infectious complications at various stages of treatment. The levels of C-reactive protein in groups of patients with localized infections (mucositis, abscess, pneumonia, etc.) or fever of unknown genesis had no statistical differences but were reliably higher in patients without infectious complications. The concentrations of C-reactive protein in patients with syndrome of systemic inflammatory response and sepsis had no differences. At the same time, level of C-reactive protein under systemic infection (syndrome of systemic inflammatory response, sepsis) was reliably higher than in case of localized infection. The diagnostically reliable levels of C-reactive protein were established as follows: lower than 11 mg/l--infectious complications are lacking; higher than 11 mg/l--availability of infectious process; higher than 82 mg/l--generalization of infection. The given levels are characterized by high diagnostic sensitivity (92% and 97% correspondingly) and specificity (97% and 97%) when patients receive therapy without application of L-asparaginase. At the stages of introduction of this preparation effecting protein synthesizing function of liver sensitivity of proposed criteria are decreased (69% and 55% correspondingly). However; due

    Full Text Available Background Childhood obesity is a major health concern. Oobesity is due to an expansion of adipose tissue mass. This tissue produces pro-inflammatory cytokines, such as interleukin-6 (IL-6. IL-6 is considered to be the chief stimulator of the production of highly sensitive C-reactive protein (hsCRP in the liver. Both molecules are responsible for the chronic low-grade inflammatory state in obese individuals. Objective To assess a correlation between IL-6 and hsCRP in obese adolescents. Methods This cross-sectional study was conducted from March to June 2011 in Manado. Subjects were obese and normal body mass index (BMI teens aged 13-18 years. Serum glutamic oxaloacetic transaminase (SGOT and serum glutamic pyruvic transaminase (SGPT levels were measured to rule out liver impairment. IL-6 and hsCRP levels were also measured. Data was analyzed by Pearson’s correlation and linear regression to test for correlation between IL-6 and hsCRP levels. Results There was a strongly positive correlation between IL-6 and hsCRP levels in obese adolescents (r=0.79 with P<0.001. IL-6 and hsCRP levels were not significantly associated in subjects with normal BMI. Conclusions There was a strongly positive correlation between IL-6 and hsCRP levels in obese adolescents, suggestive of an ongoing, chronic, low-grade inflammatory state.

    The relation between serum and synovial fluid (SF) C reactive protein (CRP) concentrations was investigated in a variety of arthritides, including rheumatoid arthritis (RA), psoriatic arthritis, reactive arthritis, and osteoarthritis. SF CRP levels were significantly reduced compared with serum levels in the inflammatory arthritides, but there was good correlation between serum and SF values. SF CRP values were all at the lower limit of the detectable range in osteoarthritis. In patients with RA or psoriatic arthritis followed up serially through an exacerbation of arthritis, changes in SF CRP reflected closely changes in serum CRP. In patients with RA SF/serum ratios of proteins of different molecular weight were used to derive a regression equation between SF/serum ratio and molecular mass. SF/serum values for CRP were significantly less than predicted from its molecular weight, suggesting that CRP is either being selectively bound in synovium or specifically consumed in SF and may be playing an important part in the inflammatory process in RA.

  17. Suppression of interleukin-6-induced C-reactive protein expression by FXR agonists

    International Nuclear Information System (INIS)

    C-reactive protein (CRP), a human acute-phase protein, is a risk factor for future cardiovascular events and exerts direct pro-inflammatory and pro-atherogenic properties. The farnesoid X receptor (FXR), a member of the nuclear hormone receptor superfamily, plays an essential role in the regulation of enterohepatic circulation and lipid homeostasis. In this study, we report that two synthetic FXR agonists, WAY-362450 and GW4064, suppressed interleukin-6-induced CRP expression in human Hep3B hepatoma cells. Knockdown of FXR by short interfering RNA attenuated the inhibitory effect of the FXR agonists and also increased the ability of interleukin-6 to induce CRP production. Furthermore, treatment of wild type C57BL/6 mice with the FXR agonist, WAY-362450, attenuated lipopolysaccharide-induced serum amyloid P component and serum amyloid A3 mRNA levels in the liver, whereas no effect was observed in FXR knockout mice. These data provide new evidence for direct anti-inflammatory properties of FXR.

    Full Text Available BACKGROUND: Pneumonia remains the leading cause of death in young children. The poor specificity of chest radiographs (CXRs to diagnose pneumococcal pneumonia may underestimate the efficacy of pneumococcal conjugate vaccine in preventing pneumococcal pneumonia. METHODS AND FINDINGS: The efficacy of nine-valent pneumococcal conjugate vaccine among children not infected with HIV (21%; 95% confidence interval, 1%-37% increased when CXR-confirmed pneumonia was associated with serum C-reactive protein of 120 mg/l (12 mg/dl or more and procalcitonin of 5.0 ng/ml or more (64%; 95% confidence interval, 23%-83%. Similar results were observed in children infected with HIV. CONCLUSION: C-reactive protein and procalcitonin improve the specificity of CXR to diagnose pneumococcal pneumonia and may be useful for the future evaluation of the effectiveness of pneumococcal conjugate vaccine in preventing pneumococcal pneumonia.

However, most immunochromatographic tests employ gold nanoparticles as reporters, and these have only moderate sensitivity and act as qualitative methods for analyzing high biomarker concentrations. Methods: In this study, we introduce quantum dots (QDs as fluorescent probes and immunochromatographic strips to develop quantitative fluorescence point-of-care tests (QF-POCT to analyze C-reactive protein (CRP levels. Goat anti-rabbit IgG and rabbit IgG were used as control antibodies, and mouse monoclonal CRP antibody pairs were used for disease marker detection. One monoclonal CRP antibody was conjugated with QDs and served as a signal antibody, and the other monoclonal CRP antibody was dispensed onto the nitrocellulose membrane and served as a capturing antibody. In the presence of CRP, the fluorescence intensity of the monoclonal antibody-CRP-monoclonal antibody sandwich complex captured on the nitrocellulose membrane was determined using the fluorescence strip reader. Results: QF-POCT assays could quantitatively analyze the concentration of CRP in 15 minutes had a detection limit of 0.25 mg/L, and had a wide detection linearity range (0.5–300 mg/L.

    In the article, a dual-quantum-dots-labeled (dual-QDs-labeled) lateral flow strip (LFS) method was developed for the simultaneous and rapid quantitative detection of procalcitonin (PCT) and C-reactive protein (CRP) in the blood. Two QD-antibody conjugates with different fluorescence emission spectra were produced and sprayed on the LFS to capture PCT and CRP in the blood. Furthermore, a double antibody sandwich method for PCT and, meanwhile, a competitive inhibition method for CRP were employ...

    C-reactive protein (CRP), a biomarker of inflammation, has been associated with increased disease activity in rheumatoid arthritis. However, the association in systemic lupus erythematosus (SLE) remains unclear. We examined the association of CRP with self-reported disease activity in the Carolina Lupus Study and described differences by sociodemographic characteristics. The study included baseline and three-year follow-up data on 107 African-American and 69 Caucasian SLE patients enrolled at...

    Full Text Available INTRODUCTION: An elevated level of serum C-reactive protein (CRP is widely considered an indicator of an underlying inflammatory disease and a long-term prognostic predictor for dialysis patients. This cross-sectional cohort study was designed to assess the correlation between the level of high-sensitivity CRP (HS-CRP and the outcome of peritoneal dialysis (PD patients. METHODS: A total of 402 patients were stratified into 3 tertiles (lower, middle, upper according to serum HS-CRP level and and followed up from October 2009 to September 2011. During follow-up, cardiovascular events, infection episodes, technique failure, and mortality rate were recorded. RESULTS: During the 24-month follow-up, 119 of 402 patients (29.6% dropped out from PD, including 28 patients (7.0% who died, 81 patients (20.1% who switched to hemodialysis, and 10 patients (2.5% who underwent kidney transplantation. The results of Kaplan-Meier analysis and log-rank test demonstrated a significant difference in the cumulative patient survival rate across the 3 tertiles (the lowest rate in upper tertile. On multivariate Cox regression analysis, only higher HS-CRP level, older age, the presence of diabetes mellitus (DM, lower serum albumin level, and the occurrence of cardiovascular events during follow-up were identified as independent predictors of mortality. Every 1 mg/L increase in HS-CRP level was independently predictive of a 1.4% increase in mortality. Multivariate Cox regression analysis also showed that higher HS-CRP level, the presence of DM, lower hemoglobin level, lower serum albumin level, higher dialysate/plasma creatinine ratio, and the occurrence of infective episodes and cardiovascular events during follow-up were independent predictors of technique failure. CONCLUSIONS: The present study shows the importance of HS-CRP in the prediction of 2-year mortality and technique survival in PD patients independent of age, diabetes, hypoalbuminemia, and the occurrence of

    C-reactive protein (CRP) is the first acute phase protein that has been described in the literature. It is phylogenetically ancient and - with serum amyloid P - belongs to proteins named as "pentraxin". After being considered a marker of acute inflammation for several decades and fruitfully used in clinical practice, CRP has been recently considered as a potential contributor to inflammatory diseases including atherosclerosis as well as a marker of cardiovascular risk. With regard to the first topic, inflammation is now believed to represent the underlying mechanism leading to the formation of human atheroma and favouring both the destabilization of vulnerable plaques and the formation of occlusive thrombi. In this regard, numerous studies indicated that modest changes in circulating CRP levels, as detected by highly sensitive methods, can be extremely useful in predicting cardiovascular and perhaps cerebrovascular diseases in apparently healthy individuals as well as in patients affected by atherosclerosis. Subjects manifesting with identical low density cholesterol and/or blood pressure levels have different rates of cardiovascular accidents on the basis of different circulating CRP concentrations. In addition, women with identical cardiovascular risk profiles developed more type 2 diabetes in the presence of higher circulating CRP levels and thereby are expected to display divergent cardiovascular prognosis. Therefore, even slight changes in circulating CRP concentrations - assuming that blood is collected appropriately and CRP is measured with correct methods - could help clinicians in defining individual cardiovascular risk. In this review, we have firstly described the current understanding of the structure of CRP, its function, and interaction with the vascular endothelial cell. Then, we have discussed how to measure circulating CRP and the more recent findings on the suggested role of circulating CRP as a novel cardiovascular risk factor. PMID:17584094

    Transfusion-related acute lung injury (TRALI) is a syndrome of respiratory distress triggered by blood transfusions and is the leading cause of transfusion-related mortality. TRALI has primarily been attributed to passive infusion of HLA and/or human neutrophil antigen antibodies present in transfused blood products, and predisposing factors such as inflammation are known to be important for TRALI initiation. Because the acute-phase protein C-reactive protein (CRP) is highly upregulated during infections and inflammation and can also enhance antibody-mediated responses such as in vitro phagocytosis, respiratory burst, and in vivo thrombocytopenia, we investigated whether CRP affects murine antibody-mediated TRALI induced by the anti-major histocompatibility complex antibody 34-1-2s. We found that BALB/c mice injected with 34-1-2s or CRP alone were resistant to TRALI, however mice injected with 34-1-2s together with CRP had significantly enhanced lung damage and pulmonary edema. Mechanistically, 34-1-2s injection with CRP resulted in a significant synergistic increase in plasma levels of the neutrophil chemoattractant macrophage inflammatory protein-2 (MIP-2) and pulmonary neutrophil accumulation. Importantly, murine MIP-2 is the functional homolog of human interleukin-8, a known risk factor for human TRALI. These results suggest that elevated in vivo CRP levels, like those observed during infections, may significantly predispose recipients to antibody-mediated TRALI reactions and support the notion that modulating CRP levels is an effective therapeutic strategy to reduce TRALI severity.

    Full Text Available The aim of this study was to compare the plasma concentration of high sensitive C-reactive protein (hs-CRP, white blood cells (WBC, uric acid, and total cholesterol (TC between soccer players and non-athletes. We also intended to evaluate the relations of blood markers with ·VO2max and body composition variables. This cross-sectional study involved professional soccer players (n=40 and sedentary young men (n=60, aged 18-22 years. Blood markers such as CRP, WBC, uric acid, and TC were determined by laboratory tests. Cardiorespiratory fitness (VO2max, body mass index (BMI and fat tissue (FM were determined by the standard test protocols. There were no significant differences between CRP levels of soccer players and non-athletes (0.32±0.13 vs. 0.34±0.19 mg/dl. CRP correlated significantly with FM among soccer players (r=0.482, p≤0.002. Our results also showed a significant correlation between TC and VO2max in soccer players (r=0.469, p≤0.002. Our results showed that long-term soccer training may have no significant effect on the CRP level

    Full Text Available Background. The sensitivity and the specificity of different methods to detect periprosthetic infection have been questioned. The current study aimed to investigate the kinetics of C-reactive protein (CRP and procalcitonin (PCT in patients undergoing uncomplicated elective total hip arthroplasty (THA, to provide a better interpretation of their levels in noninfectious inflammatory reaction. Methods. A total of 51 patients were included. Serum CRP and PCT concentrations were obtained before surgery, on the 1st, 3rd, and 7th postoperative days and after discharge on the 14th and 30th days and at 2 years. Results. Both markers were confirmed to increase after surgery. The serum CRP showed a marked increase on the 3rd postoperative day while the peak of serum PCT was earlier, even if much lower, on the first day. Then, they declined slowly approaching the baseline values by the second postoperative week. PCT mean values never exceed concentrations typically related to bacterial infections. Conclusions. CRP is very sensitive to inflammation. It could be the routine screening test in the follow-up of THA orthopaedic patients, but it should be complemented by PCT when there is the clinical suspicion of periprosthetic infection.

  6. Interactions between C-Reactive Protein Genotypes with Markers of Nutritional Status in Relation to Inflammation

    Full Text Available Inflammation, as indicated by C-reactive protein concentrations (CRP, is a risk factor for chronic diseases. Both genetic and environmental factors affect susceptibility to inflammation. As dietary interventions can influence inflammatory status, we hypothesized that dietary effects could be influenced by interactions with single nucleotide polymorphisms (SNPs in the CRP gene. We determined 12 CRP SNPs, as well as various nutrition status markers in 2010 black South Africans and analyzed their effect on CRP. Interactions were observed for several genotypes with obesity in determining CRP. Lipid intake modulated the pro-inflammatory effects of some SNPs, i.e., an increase in both saturated fatty acid and monounsaturated fatty acid intake in those homozygous for the polymorphic allele at rs2808630 was associated with a larger increase in CRP. Those harboring the minor alleles at rs3093058 and rs3093062 presented with significantly higher CRP in the presence of increased triglyceride or cholesterol intake. When harboring the minor allele of these SNPs, a high omega-6 to -3 ratio was, however, found to be anti-inflammatory. Carbohydrate intake also modulated CRP SNPs, as HbA1C and fasting glucose levels interacted with some SNPs to influence the CRP. This investigation highlights the impact that nutritional status can have on reducing the inherent genetic susceptibility to a heightened systemic inflammatory state.

    Full Text Available SUMMARY Chagas disease is a public health problem worldwide. The availability of diagnostic tools to predict the development of chronic Chagas cardiomyopathy is crucial to reduce morbidity and mortality. Here we analyze the prognostic value of adenosine deaminase serum activity (ADA and C-reactive protein serum levels (CRP in chagasic individuals. One hundred and ten individuals, 28 healthy and 82 chagasic patients were divided according to disease severity in phase I (n = 35, II (n = 29, and III (n = 18. A complete medical history, 12-lead electrocardiogram, chest X-ray, and M-mode echocardiogram were performed on each individual. Diagnosis of Chagas disease was confirmed by ELISA and MABA using recombinant antigens; ADA was determined spectrophotometrically and CRP by ELISA. The results have shown that CRP and ADA increased linearly in relation to disease phase, CRP being significantly higher in phase III and ADA at all phases. Also, CRP and ADA were positively correlated with echocardiographic parameters of cardiac remodeling and with electrocardiographic abnormalities, and negatively with ejection fraction. CRP and ADA were higher in patients with cardiothoracic index ≥ 50%, while ADA was higher in patients with ventricular repolarization disturbances. Finally, CRP was positively correlated with ADA. In conclusion, ADA and CRP are prognostic markers of cardiac dysfunction and remodeling in Chagas disease.

    Inducible serum proteins whose concentrations oscillate between nontolerogenic and tolerogenic levels pose a particular challenge to the maintenance of self-tolerance. Temporal restrictions of intrathymic antigen supply should prevent continuous central tolerization of T cells, in analogy to the spatial limitation imposed by tissue-restricted antigen expression. Major acute-phase proteins such as human C-reactive protein (hCRP) are typical examples for such inducible self-antigens. The circul...

    Hypertension with high homocysteine (HHcy) (H-type hypertension) and C reactive protein (CRP) can increase the incidence of ischemic stroke. However, it is not clear whether recurrent ischemic stroke (RIS) is related to H-type hypertension and CRP. The present study investigated the correlation of H-type hypertension and CRP level with RIS. Totally, 987 consecutive patients with acute ischemic stroke were recruited in a teaching hospital in Henan province, China during March 2014 to March 2015. The demographic and clinical characteristics and blood biochemical parameters of patients were analyzed. Elevated levels of CRP and homocysteine (Hcy) were defined as >8.2 mg/L and 10 μmol/L, respectively. Among the 987 patients, 234 were RIS. Thirty-eight percent of RIS patients had elevated CRP level and 91.5% of RIS patients had HHcy. In multivariate analysis, adjusted odds ratio (OR) of RIS in patients aged ≥60 years was 1.576 (95% CI: 1.125-2.207), in male patients 1.935 (95% CI: 1.385-2.704), in patients with diabetes 1.463 (95% CI: 1.037-2.064), CRP levels 1.013 (95% CI: 1.006-1.019), simple hypertension 3.370 (95% CI: 1.15-10.183), and H-type hypertension 2.990 (95% CI: 1.176-7.600). RIS was associated with older age, male, diabetes, H-type hypertension and CRP. Controlling H-type hypertension and CRP level may reduce the risk of RIS. PMID:27164124

  10. Adiponectin and C - reactive protein Relationship in the Polycystic Ovary Syndrome: Relation to Cardiovascular Disease

    International Nuclear Information System (INIS)

    The polycystic ovary syndrome (PCOS), one of the most common reproductive abnormalities, shares some components of the metabolic cardiovascular syndrome. Therefore, PCOS patients may represent the largest group of women at high risk for the development of early-onset cardiovascular disease (CVD) and/or diabetes. The adipokine, adiponectin inhibits vascular inflammation and acts as an endogenous modulator of obesity - linked diseases. High - sensitive C-reactive protein (hs-CRP) is recently debated as a risk factor and mediator for atherosclerosis. The objective of this study was to investigate the relation between adiponectin and hs- CRP in The Polycystic Ovary Syndrome and to identify their relation to Cardiovascular Disease. Adiponectin and hs- CRP measurements were undertaken in 90 PCOS patients and 70 body mass index-matched controls with regular menstrual cycles. Whereas 36.8% of the PCOS patients had CRP levels above 5 mg/liter, only 9.6% of the controls exhibited high CRP levels (P < 0.001). The mean ± SD was 5.46 ± 7.0 in the PCOS group vs. 2.04 ± 1.9 mg/liter in the control (P < 0.001). The body mass index, white blood cell count, TSH, glucose, cholesterol, and homocysteine levels were not significantly different between the two groups. CRP levels are elevated in patients with PCOS and may be a marker of early cardiovascular risk in these patients. The plasma adiponectin levels being significantly lower in these patients. These results suggest that elevation of CRP and reduction of adiponectin could emerge as mediators of atherogenesis and insulin resistance. (author)

The objective of this study was to investigate whether levels of procalcitonin (PCT, C-reactive protein (CRP, and neopterin in COPD patients could be useful in identifying the etiological origin of the exacerbation and assessing its prognosis.Methods: We included 318 consecutive COPD patients: 46 in a stable phase, 217 undergoing an exacerbation, and 55 with pneumonia. A serum sample was collected from each patient at the time of being included in the study. A second sample was also collected 1 month later from 23 patients in the exacerbation group. We compared the characteristics, biomarker levels, microbiological findings, and prognosis in each patient group. PCT and CRP were measured using an immunofluorescence assay. Neopterin levels were measured using a competitive immunoassay.Results: PCT and CRP showed significant differences among the three patient groups, being higher in patients with pneumonia, followed by patients with exacerbation (P < 0.0001. For the 23 patients with paired samples, PCT and CRP levels decreased 1 month after the exacerbation episode, while neopterin increased. Neopterin showed significantly lower levels in exacerbations with isolation of pathogenic bacteria, but no differences were found for PCT and CRP. No significant differences were found when comparing biomarker levels

    Full Text Available Context: C-reactive protein (CRP is an acute phase reactant, widely used as a biomarker for various infectious and inflammatory conditions. Guillain-Barrι syndrome (GBS is an acute, autoimmune, polyradiculoneuropathy, triggered by infectious agents such as Campylobacter jejuni. GBS is generally precipitated 1-3 weeks following C. jejuni infection which suggests a humoral immunopathogenic mechanism. Aims: Basal CRP levels were estimated in sera of patients with GBS and compared with adequate controls. Settings & Design: The study population was divided into 4 groups: (i GBS group included 45 newly diagnosed GBS patients; (ii Neurological control (NC group comprised of 59 patients with non-paralytic neurological symptoms/disorders; (iii Non-neurological controls (NNC comprised of 43 patients having no neurological symptoms and (iv Healthy controls (HC comprised of 101 healthy subjects. Materials and Methods: CRP was evaluated using slide latex agglutination test (LAT and enzyme linked immunosorbent assay (ELISA. Statistical Analysis: Statistical analysis was done by the Chi-square test. Results: CRP by LAT was positive in 24.4% GBS group, 34% NC group and 44% NNC group. The range of titer in CRP positive samples in the three patient groups (GBS, NC, NNC was at concentration of 0.6 mg/dl to 19.2 mg/dl. Similar results were also obtained by ELISA in the patient groups. None of the HC subjects was positive for detectable levels of CRP. High basal level of CRP was detected in patients with GBS. Conclusion: Autoimmune conditions like GBS can stimulate the production of a high level of inflammation resulting in an increase in the CRP production.

    Full Text Available Sepsis appears to be due to an uncontrolled pro and anti-inflammatory response leading to organ dysfunction until shock and death.Accuracy of diagnosis and appropriate treatment affect the outcome. Aim of the study was to investigate if the levels of Osteopontin (OPN and Soluble Urokinase-type Plasminoge Activator Receptor (suPAR might be early markers of sepsis and if these markers play a role in predicting the progression to septic shock. Methods:The levels of OPN, suPAR, C-reactive protein (CRP and procalcitonin (PCT were measured in patients at higher risk of infection. The samples were collected from the day of admission for the following fifteenth day. During recovery Sistemic Inflammatory Response Syndrome (SIRS criteria, blood chemistry data, blood gas- analysis, lactate and diuresis were collected. Microbiological culture were performed according to the clinical condition. Results: 29 patients were enrolled in the study, including 14 subjects with positive blood cultures.The values of OPN, PCT, suPAR and CRP were significantly increased in patients with positive blood cultures than those with negative blood cultures.Analysing changes of the levels of OPN, suPAR, PCT and CRP in patients with septic shock, the values of OPN increased in advance to the clinical diagnosis of septic shock, while the values of suPAR and PCT slight delay compared to those OPN.The levels of CRP were independent from the onset of septic shock state. Conclusions: These preliminary data suggest that Osteopontin and suPAR can be used as early markers of sepsis and might be useful in monitoring of septic outcome to predict a possible evolution to septic shock.

  15. Preoperative serum C- reactive protein: a prognostic marker in patients with upper urinary tract urothelial carcinoma

    International Nuclear Information System (INIS)

    To analyse the prognostic significance of preoperative C-reactive protein (CRP) serum level in patients with upper urinary tract urothelial carcinoma (UUT-UC). We evaluated 158 UUT-UC patients who had undergone surgery in the University Hospital of Hannover (MHH). 143 (89.4%) suffered from cancer in the renal pelvis, 13 (8.1%) patients presented with tumour located in the ureter. A preoperative CRP value was available for 115 patients. The mean (median) follow-up for these patients was 28.3 (15.1) months. The median (mean) CRP value of all evaluable patients was 10.0 (40.7) mg/l. The CRP-level, stratified into two subgroups (CRP ≤5 vs. >5 mg/l), correlated significantly with muscle invasive tumour stage (36.4 vs. 78.9%; p<0.001), the risk of presenting nodal disease (4.5 vs. 26.8%; p=0.002) and distant metastasis (2.3 vs. 16.9%; p<0.016). The Kaplan-Meier 5-year cancer specific survival (CSS) rates were 54.2 and 26.4% for patients with preoperative CRP levels ≤ and >5 mg/l, respectively (p<0.006). Next to age and the presence of metastasis, multivariate analysis also identified CRP as a continuous variable as an independent prognosticator for CSS. A high preoperative serum CRP level is associated with locally advanced and metastatic disease in patients with UUT-UC. Its routine use could allow better risk stratification and risk-adjusted follow-up of UUT-UC patients

    Several prospective studies suggest that C-reactive protein (CRP), a nonspecific serologic marker of inflammation, might be linked to risk of colorectal cancer (CRC), whereas others have reported null or protective effects. We analyzed data from 7,072 participants (50-85 years) in the U.S. National Health and Nutrition Examination Survey III (1988-1994), a nationally representative cohort (n = 33,994; 2 months-85 years) with vital status follow-up to 2000. Hazard ratios (HRs) for mortality associated with baseline clinically raised (≥1.00 mg/dL) and intermediate (≥0.22-0.99 mg/dL) CRP levels were estimated using Cox proportional hazards regression controlling for CRC risk factors. There were 59 deaths from CRC, 106 from other obesity-related cancers (other-ORCs) and 1,130 from cardiovascular disease (CVD). Participants with clinically raised CRP at baseline were found to have a statistically significant greater risk of CRC death (HRs = 2.36-2.47) in comparison to persons with undetected levels. HRs were lower for death from other-ORC and CVD (1.82, 95% CI 1.05-3.15; 1.53, 95% CI 1.29-1.81, respectively). Intermediate CRP level was associated with a nonsignificant 10-21% increased risk for CRC death. HR for CRC death was higher among persons with a normal BMI (2.16, 95% 0.96-4.87, p = 0.06) compared to those who were overweight (1.22, 95% CI 0.53-2.78) or obese (1.23, 95% CI, 0.37-4.08). A similar pattern was observed for waist circumference. This effect modification suggests that the impact of chronic inflammation may be independent of excess body fat. Future research is recommended to confirm emerging data that elevated serologic CRP might reflect underlying colonic inflammation. PMID:24122448

    It is hypothesized that chronic systemic inflammation contributes to the age-related decline in cardiovascular function. The aim of the present study was to combine an assessment of the relationship between the serum level of C-reactive protein (CRP) and systolic and diastolic blood pressure in 108 elderly women (65 and 70 years) with an in-vitro exploration of the effects of CRP on the proliferative and angiogenic potential of endothelial cells exposed to serum in elderly women. Based on the median CRP level in our population, LowCRP (CRP1.3mg/L) groups were identified. Body mass index, waist circumference, systolic blood pressure (SBP) and diastolic blood pressure (DBP) were significantly higher in the HighCRP group than in the LowCRP group (pCRP on SBP and DBP remained significant after adjustments for BMI and use of antihypertensive medication (pCRP on SPB was attenuated (p=0.062). We next evaluated the ability to form capillary tubes (angiogenesis assay) and the proliferation rate of endothelial cells exposed to the sera of elderly women. Increased serum CRP levels were associated with an increased doubling time of endothelial cells (R(2)=0.39; p<0.05) and decreased capillary tube length (R(2)=0.30; p<0.05), indicating a reduction in the proliferation rate of endothelial cells and angiogenic potential. In conclusion, chronic inflammation influences blood pressure in elderly women and compromises endothelial cell function, thus contributing to the age-related decline in vascular health.

    Full Text Available Context: Although there are several studies reported in the western literature regarding the association of C reactive protein (CRP level with components of metabolic syndrome, data in the Indian population were lacking. As there will be a considerable difference in the profile of risk factors for cardiovascular diseases (CVDs, studies regarding the correlation of CRP level with cardiovascular risk factors and metabolic syndrome in the Indian population are required. Objective: To correlate the highly sensitive CRP (hsCRP level to individual components of metabolic syndrome and coronary vascular disease. Materials and Methods : Forty patients who were diagnosed clinically with metabolic syndrome were included in the study. Detailed history with regard to diabetes mellitus, hypertension and other CVD was collected from each patient. All the patients underwent complete physical examination, including ECG. Height, weight, fasting blood glucose and lipid levels were measured in all the patients. CVD was assessed with the following: new-onset angina, fatal and non-fatal myocardial infarction or stroke, transient ischemic attack, heart failure or intermittent claudication. Results: The mean hsCRP level was higher in patients with CVD compared with those without CVD. The CRP level correlation with CVD showed a statistically significant correlation. hsCRP level was very high in eight hypertensive patients, whereas it was very high in five normotensives. But, statistical analysis has not shown any significant correlation between hypertension and hsCRP level. Similarly, although a higher hsCRP level was seen in diabeteics, statistical analysis failed to show a significant correlation between diabetes and the hsCRP level. Analyses of hsCRP correlation with body mass index, fasting glucose, cholesterol, triglycerides, high-density lipoprotein and low-density lipoprotein did not show a significant correlation with the hsCRP level. Conclusions: Increased hs

    Full Text Available Background and Objective: C - reactive protein (CRP is an acute phase protein produced in liver. It is less than 5 mg per deciliter in the serum and body fluids of normal individuals, but it is increased suddenly within a few hours following inflammatory reaction. In bacterial and viral infections, active rheumatic fever, acute myocardial infarction and rheumatoid arthritis are also increased. The aim of this study was to investigate CRP level by Qualitative and Quantitative methods. Material and Methods: The CRP of 200 patients was investigated by quantitative and qualitative methods. Qualitative CRP testing was conducted three times by different people, using two kit of bionic and Omega, and then the mean of the results was reported. For quantitative CRP testing, Immunoturbidimetry was used. Results: In qualitative CRP test by Bionic kit: 180 (90% were negative, 6 (3% weakly positive, 9 (4.5% +1 and 5 (2.5 % were + 2. In qualitative CRP test by Omega Kit: 148 (74% were negative, 32 (16% weakly positive, 13 (6.5% +1, 4 (2% +2 and 3 (1.5% were +3. A high percentage of Qualitative results, which were weakly positive, became negative by Quantitative methods. The Qualitative results of +1 and the next became positive by Quantitative methods. Conclusion: It seems that in the early stages of inflammatory disease, quantitative methods are preferred to qualitative methods. Also, in cases that the CRP test results are weakly positive by qualitative methods, they should be controlled by quantitative methods too. Keywords: CRP; CRP Test Quantitative; Qualitative CRP Test

    To establish whether C-reactive protein (CRP) is an independent predictor of all-cause mortality and hospitalization in chronic obstructive pulmonary disease (COPD), we followed 200 patients with COPD and 201 age- and gender -matched controls for a median time of 4.2 years (range, 0.2-5.1 years). Airflow obstruction was rated moderate if forced expiratory volume in one second (FEV(1)) was 50-69% of the predicted value, or severe if FEV(1) was 3 mg/L). The hazard of death was estimated by a proportional hazard regression model, using controls with low CRP as the reference category. Fifty subjects died: 41 (21%) among the COPD and 9 (4%) among the controls (p < 0.0001). The hazard of death in moderate COPD was not significantly higher than in the reference category, independently of the CRP level. In severe COPD with a low CRP, the hazard of death is 3.4 times higher than in the reference category (p = 0.008); in severe COPD and a high CRP it is 9.6 times higher (p < 0.0001). The rate of hospitalization in COPD patients with a high CRP is 1.9 times higher than in those with a low CRP [95% confidence interval (CI), 1.2-3.2]. In severe COPD, it is 6.9 times higher than in moderate COPD (95% CI, 3.8-12.7). A high CRP level is a significant amplifier of the risk of death only in severe COPD. The degree of airflow obstruction is a strong independent predictor of COPD-related outcomes. PMID:21249472

    Background Epidemiological findings suggest a relationship between Alzheimer's disease (AD), inflammation and dyslipidemia, although the nature of this relationship is not well understood. We investigated whether this phenotypic association arises from a shared genetic basis. Methods and Results Using summary statistics (p-values and odds ratios) from genome-wide association studies of over 200,000 individuals, we investigated overlap in single nucleotide polymorphisms (SNPs) associated with clinically diagnosed AD and C-reactive protein (CRP), triglycerides (TG), high- (HDL) and low-density lipoprotein (LDL) levels. We found up to 50-fold enrichment of AD SNPs for different levels of association with CRP, LDL, HDL and TG SNPs using an FDR threshold < 0.05. By conditioning on polymorphisms associated with the four phenotypes, we identified 55 loci associated with increased AD risk. We then conducted a meta-analysis of these 55 variants across four independent AD cohorts (total n = 29,054 AD cases and 114,824 healthy controls) and discovered two genome-wide significant variants on chromosome 4 (rs13113697, closest gene HS3ST1, odds ratio (OR) = 1.07, 95% confidence interval (CI) = 1.05-1.11, p = 2.86 × 10−8) and chromosome 10 (rs7920721, closest gene ECHDC3, OR = 1.07, 95% CI = 1.04-1.11, p = 3.38 × 10−8). We also found that gene expression of HS3ST1 and ECHDC3 was altered in AD brains compared with control brains. Conclusions We demonstrate genetic overlap between AD, CRP, and plasma lipids. By conditioning on the genetic association with the cardiovascular phenotypes, we identify novel AD susceptibility loci including two genome-wide significant variants conferring increased risk for Alzheimer's disease.

    Full Text Available Aims and Objectives: The aim of the present study was to investigate systemic levels of inflammatory markers of cardiovascular diseases like C-reactive protein and interleukin-6 in patients with chronic periodontitis, in comparison to periodontally healthy individuals. Materials and Methods: A total of 42 individuals, both males and females above the age of 30 years, were included in the study. Healthy controls (Group I, n = 14, chronic localized periodontitis (Group II, n = 14, and chronic generalized periodontitis (Group III, n = 14, all without any medical disorder, were recruited. Peripheral blood samples were taken and C-reactive protein (CRP levels were estimated in the serum samples by using the Particle-Enhanced Turbidimetric Immunoassay (PETIA technique. Serum samples of Interleukin-6 (IL-6 were assayed by using the Chemiluminescent Immunoassay (IMMULITE technique. Results: When mean CRP levels were compared between the groups, group III showed statistical significance when compared to group I (P = 0.04. Group III had a higher median IL-6 level (6.35 pg/mL than Group II (< 5.0 pg/ mL and group I (< 5.0 pg/mL. Differences in median values of IL-6 were not statistically significant in any group (P = 0.29. Conclusion: Periodontitis results in higher systemic levels of CRP and IL-6. These elevated inflammatory factors may increase inflammatory activity in atherosclerotic lesions and potentially increasing the risk for cardiovascular events.

  14. Expression, crystallization and preliminary crystallographic analysis of C-reactive protein from zebrafish

    International Nuclear Information System (INIS)

    Crystals of native and selenomethionine-substituted C-reactive protein from zebrafish diffracted to 2.3 and 1.7 Å resolution, respectively, and belonged to space group R3 with one molecule per asymmetric unit. The Matthews coefficient was calculated to be 3.28 Å3 Da−1. C-reactive protein (CRP) is an acute phase protein that is found in blood, the concentration of which in plasma rises rapidly in response to inflammation. It functions as a pattern-recognition molecule, recognizing dead cells and various pathogenic agents and eliminating them by utilizing the classical complement pathway and activating macrophages. CRP is phylogenetically highly conserved in invertebrates and mammals. To date, information on the CRP gene has been reported from numerous species of animals, but little is known about the structure of CRP from species other than humans. In order to solve the structure of CRP from bony fish, the CRP gene from zebrafiah (Danio rerio) was cloned and expressed in Escherichia coli. The zebrafish CRP (Dare-CRP) was then purified and crystallized. The crystal diffracted to 2.3 Å resolution and belonged to space group R3, with unit-cell parameters a = b = 114.7, c = 61.0 Å. The Matthews coefficient and solvent content were calculated to be 3.28 Å3 Da−1 and 62.55%, respectively. Determination of the zebrafish CRP structure should be helpful in investigating the evolution of CRPs in the innate immune system

    Background: Migarine is the most common headache around the world including Iran. In recent years, Vitamin D deficiency has been shown to a global health problem. A few studies have been determined inverse association between serum levels of Vitamin D with a headache. So, in this study, we investigated the effect of Vitamin D supplementation on symptoms and C-reactive protein (CRP) among patients with migraine. Materials and Methods: This study was randomized, double-blind, and controlled-placebo clinical trial. Sixty-five migraine patients aged 10-61 years were included for analysis. Vitamin D was administrated for 10 weeks with 50,000 IU dosage of Vitamin D per week. Multivariate analysis of covariate and univariate analysis of covariate were done to determine the effects of Vitamin D supplementation on symptoms, including severity, duration, frequency of headache, and the headache diary result (HDR). Results: Mean headache frequency and HDR had significant difference among two groups (5.9 ± 7.0 vs. 7.0 ± 6.0, P = 0.06 and 85.0 ± 134.2 vs. 132.1 ± 147.1, P = 0.04). But, a mean difference of headache frequency was marginally significant (P = 0.06). These values were lower among the intervention group compared to placebo group. The association was not observed between CRP with migraine disease. Conclusion: In this study, we shown Vitamin D supplementation may be useful in decreasing frequency of headache attacks and HDR among patients with migraine. PMID:26487877

    Full Text Available Aim: Febrile neutropenia is the major cause of mortality and morbidity in cancer patients. For this reason, early diagnosis of severe infections and appropriate antimicrobial therapy are very important. The aim of this study was to investigate the difference between C-reactive protein (CRP and procalcitonin in determining the sepsis and its severity. Materials and Method: A total of 30 children (35 episodes with febrile neutropenia who were hospitalized in the Uludag University, Pediatric Hematology and Oncology Unit were included in this prospective study. The blood samples for CRP and procalcitonin were collected daily between 0 to 5th days. Serum CRP and procalcitonin levels were compared with culture positivity, prolonged fever, mucositis and absolute granulosit count (AGC. Results: A total of 16 patients (56% diagnosed with acute leukemia and, 14 patients (46% having solid tumours were evaluated. In sequential analysis of febrile episodes, both the median of procalcitonin and the CRP concentrations showed the same tendency and there was no significant correlation between them (r=0.2, p>0.05. There was no significant association between CRP and procalcitonin among those having positive culture and mucositis. However, CRP values at the 3rd, 4th and 5th days were significantly higher in the patients with AGC100/mm3. Similarly, CRP values were significantly higher at the 1st, 2nd, 3rd and 4th days among the patients having prolonged fever. Conclusion: Our study suggests that there is no difference between CRP and procalcitonin in determining sepsis and its severity. Although procalcitonin is a valuable acute phase reactant in non-neutropenic patients, larger prospective investigations are needed to show the prognostic value of procalcitonin in neutropenic patients.

    The incremental prognostic value of plasma levels of C-reactive protein (CRP) in relation to GRACE score has not been established in patients with acute coronary syndrome (ACS) with non-ST segment elevation. To test the hypothesis that CRP measurements at admission increases the prognostic value of GRACE score in patients with ACS. A total of 290 subjects, consecutively admitted for ACS, with plasma material obtained upon admission CRP measurement using a high-sensitivity method (nephelometry) were studied. Cardiovascular outcomes during hospitalization were defined by the combination of death, nonfatal myocardial infarction or nonfatal refractory angina. The incidence of cardiovascular events during hospitalization was 15% (18 deaths, 11 myocardial infarctions, 13 angina episodes) with CRP showing C-statistics of 0.60 (95% CI = 0.51-0.70, p = 0.034) in predicting these outcomes. After adjustment for the GRACE score, elevated CRP (defined as the best cutoff point) tended to be associated with hospital events (OR = 1.89, 95% CI = 0.92 to 3.88, p = 0.08). However, the addition of the variable elevated CRP in the GRACE model did not result in significant increase in C-statistics, which ranged from 0.705 to 0.718 (p = 0.46). Similarly, there was no significant reclassification of risk with the addition of CRP in the predictor model (net reclassification = 5.7 %, p = 0.15). Although CRP is associated with hospital outcomes, this inflammatory marker does not increase the prognostic value of the GRACE score.

    Full Text Available Background/Aim: Acute appendicitis is one of the most common acute intraabdominal affections seen in surgical departments, which can be treated easily if an accurate diagnosis is made in time. Otherwise, delay in diagnosis and treatment can lead to diffuse peritonitis. Materials and Methods: A study was conducted on 110 patients who were operated for acute appendicitis to determine the role and predictive value of the total leucocyte count (TLC, C-reactive protein (CRP and percentage of neutrophil count in the diagnosis of acute appendicitis. Preoperative TLC, CRP and percentage of neutrophil count were determined and were compared with the results of the histopathology of the removed appendix. Results: Of all the patients studied, 92 had histopathologically positive appendicitis. The TLC was found to be significantly high in 90 patients who proved to have acute appendicitis, whereas CRP was high in only 88 patients and neutrophil percentage was raised in 91; four had a normal CRP level. Thus, TLC had a sensitivity, specificity and positive predictive value of 97.82%, 55.55% and 91.8%, respectively. CRP had a sensitivity, specificity and positive predictive value of 95.6%, 77.77% and 95.6% respectively. Percentage of neutrophil count had a sensitivity, specificity and positive predictive value of 98.9%, 38.88% and 89.21%, respectively. When used in combination, there was a marked improvement in the specificity and the positive predictive value to 88.04% and 98.7%, respectively. Conclusion: The inflammatory markers, i.e., TLC, CRP and neutrophil count can be helpful in the diagnosis when measured together as this increases their specificity and positive predictive value.

  1. Does high C-reactive protein concentration increase atherosclerosis? The Whitehall II Study.

    Directory of Open Access Journals (Sweden)

    Mika Kivimäki

    Full Text Available BACKGROUND: C-reactive protein (CRP, a marker of systemic inflammation, is associated with risk of coronary events and sub-clinical measures of atherosclerosis. Evidence in support of this link being causal would include an association robust to adjustments for confounders (multivariable standard regression analysis and the association of CRP gene polymorphisms with atherosclerosis (Mendelian randomization analysis. METHODOLOGY/PRINCIPAL FINDINGS: We genotyped 3 tag single nucleotide polymorphisms (SNPs [+1444T>C (rs1130864; +2303G>A (rs1205 and +4899T>G (rs 3093077] in the CRP gene and assessed CRP and carotid intima-media thickness (CIMT, a structural marker of atherosclerosis, in 4941 men and women aged 50-74 (mean 61 years (the Whitehall II Study. The 4 major haplotypes from the SNPs were consistently associated with CRP level, but not with other risk factors that might confound the association between CRP and CIMT. CRP, assessed both at mean age 49 and at mean age 61, was associated both with CIMT in age and sex adjusted standard regression analyses and with potential confounding factors. However, the association of CRP with CIMT attenuated to the null with adjustment for confounding factors in both prospective and cross-sectional analyses. When examined using genetic variants as the instrument for serum CRP, there was no inferred association between CRP and CIMT. CONCLUSIONS/SIGNIFICANCE: Both multivariable standard regression analysis and Mendelian randomization analysis suggest that the association of CRP with carotid atheroma indexed by CIMT may not be causal.

    Full Text Available C-reactive protein (CRP, a blood inflammatory biomarker, is associated with the development of Alzheimer disease. In animal models of Parkinson disease (PD, systemic inflammatory stimuli can promote neuroinflammation and accelerate dopaminergic neurodegeneration. However, the association between long-term systemic inflammations and neurodegeneration has not been assessed in PD patients.To investigate the longitudinal effects of baseline CRP concentrations on motor prognosis in PD.Retrospective analysis of 375 patients (mean age, 69.3 years; mean PD duration, 6.6 years. Plasma concentrations of high-sensitivity CRP were measured in the absence of infections, and the Unified Parkinson's Disease Rating Scale Part III (UPDRS-III scores were measured at five follow-up intervals (Days 1-90, 91-270, 271-450, 451-630, and 631-900.Change of UPDRS-III scores from baseline to each of the five follow-up periods.Change in UPDRS-III scores was significantly greater in PD patients with CRP concentrations ≥0.7 mg/L than in those with CRP concentrations <0.7 mg/L, as determined by a generalized estimation equation model (P = 0.021 for the entire follow-up period and by a generalized regression model (P = 0.030 for the last follow-up interval (Days 631-900. The regression coefficients of baseline CRP for the two periods were 1.41 (95% confidence interval [CI] 0.21-2.61 and 2.62 (95% CI 0.25-4.98, respectively, after adjusting for sex, age, baseline UPDRS-III score, dementia, and incremental L-dopa equivalent dose.Baseline plasma CRP levels were associated with motor deterioration and predicted motor prognosis in patients with PD. These associations were independent of sex, age, PD severity, dementia, and anti-Parkinsonian agents, suggesting that subclinical systemic inflammations could accelerate neurodegeneration in PD.

  3. Arsenite activates NFκB through induction of C-reactive protein

    International Nuclear Information System (INIS)

    C-reactive protein (CRP) is an acute phase protein in humans. Elevated levels of CRP are produced in response to inflammatory cytokines and are associated with atherosclerosis, hypertension, cardiovascular disease and insulin resistance. Exposure to inorganic arsenic, a common environmental toxicant, also produces cardiovascular disorders, namely atherosclerosis and is associated with insulin-resistance. Inorganic arsenic has been shown to contribute to cardiac toxicities through production of reactive oxygen species (ROS) that result in the activation of NFκB. In this study we show that exposure of the hepatic cell line, HepG2, to environmentally relevant levels of arsenite (0.13 to 2 μM) results in elevated CRP expression and secretion. ROS analysis of the samples showed that a minimal amount of ROS are produced by HepG2 cells in response to these concentrations of arsenic. In addition, treatment of FvB mice with 100 ppb sodium arsenite in the drinking water for 6 months starting at weaning age resulted in dramatically higher levels of CRP in both the liver and inner medullary region of the kidney. Further, mouse Inner Medullary Collecting Duct cells (mIMCD-4), a mouse kidney cell line, were stimulated with 10 ng/ml CRP which resulted in activation of NFκB. Pretreatment with 10 nM Y27632, a known Rho-kinase inhibitor, prior to CRP exposure attenuated NFκB activation. These data suggest that arsenic causes the expression and secretion of CRP and that CRP activates NFκB through activation of the Rho-kinase pathway, thereby providing a novel pathway by which arsenic can contribute to metabolic syndrome and cardiovascular disease. -- Highlights: ► Exposure to arsenic can induce the expression and secretion of CRP. ► Mice treated with NaAsO2 showed higher levels of CRP in both the liver and kidney. ► mIMCD-3 were stimulated with CRP which resulted in activation of NFκB. ► CRP activates NFκB through activation of the Rho-kinase pathway. ► Data provide

    Although human C-reactive protein (CRP) becomes upregulated during septicemia, its role remains unclear, since purified CRP showed no binding to many common pathogens. Contrary to previous findings, we show that purified human CRP (hCRP) binds to Salmonella enterica, and that binding is enhanced in...... the presence of plasma factors. In the horseshoe crab, Carcinoscorpius rotundicauda, CRP is a major hemolymph protein. Incubation of hemolymph with a range of bacteria resulted in CRP binding to all the bacteria tested. Lipopolysaccharide-affinity chromatography of the hemolymph co-purified CRP......, galactose-binding protein (GBP) and carcinolectin-5 (CL5). Yeast two-hybrid and pull-down assays suggested that these pattern recognition receptors (PRRs) form pathogen recognition complexes. We show the conservation of PRR crosstalk in humans, whereby hCRP interacts with ficolin (CL5 homologue). This...

CRP (with high sensitivity immuno-nephelometric assay, APhL (with solid phase immuno-enzyme assay, plasma lipids were evaluated, sonography with measurement of intima-media complex (IMC thickness of common carotid arteries, carotid artery bulbs and internal carotid arteries, electrocardiography (ECG, echocardiography (EchoCG, Holter ECG monitoring were performed. Results. HsCRP serum level in pts was significantly higher than in control: 2,55 [0,71; 7,04] mg/l (varied from 0,15 to 39,85 vs 0,68 [0,26; 1,97] mg/l (varied from 0,1 to 9,61, p<0,001. Most high hsCRP concentration was found in SLE with APS (p=0,02. HsCRP level in pts with PAPS with history of combined or isolated arterial thrombosis was significantly higher than in pts with SLE and APS having the same localization of thrombosis. HsCRP concentration less than 3 mg/l correlated with duration of postthrombotic period in pts with PAPS. HsCRP level also correlated with triglyceride concentration, body mass index, summated coronary risk and magistral arteries IMC thickness. Conclusion. HsCRP elevation in pts with APS was associated with development of combined and arterial thrombosis as well as with traditional risk factors of atherosclerosis.

    Previous studies have suggested that low-grade systemic inflammation is involved in the pathogenesis of type 2 diabetes mellitus. However, limited information is available about the relationship of diabetes mellitus and inflammation in Asia. We examined the association between high-sensitivity C-reactive protein (CRP) levels and diabetes in a general Iranian population. In an ancillary study to the Persian Gulf Healthy Heart Study, a cohort study of men and women aged > or = 25 years, a random sample of 1754 (49.2 percent males, 50.8 percent females) subjects were evaluated. High sensitivity C-reactive protein was measured by enzyme-linked immunosorbent assay. Elevated serum CRP was defined as more than 3.0 mg/l. The diabetes classification was based on the criteria of the American Diabetes Association. A total of 8.6 percent of the subjects (8.0 percent of males & 9.1 percent of females; p>0.05) had type 2 diabetes mellitus. Geometric mean of CRP was 1.94 mg/l (3.80 SD) in the studied population. The subjects with diabetes had a higher geometric mean of CRP levels than the subjects with no diabetes [3.67 (SD 3.71) versus 1.85 (3.83) respectively; pstrategies for diabetes mellitus.

    Full Text Available Min-Ho Lee, Kuk-Nyung Lee, Suk-Won Jung, Won-Hyo Kim, Kyu-Sik Shin, Woo-Kyeong SeongKorea Electronics Technology Institute, Gyeonggi, KoreaAbstract: A silicon nanowire-based sensor for biological application showed highly desirable electrical responses to either pH changes or receptor-ligand interactions such as protein disease markers, viruses, and DNA hybridization. Furthermore, because the silicon nanowire can display results in real-time, it may possess superior characteristics for biosensing than those demonstrated in previously studied methods. However, despite its promising potential and advantages, certain process-related limitations of the device, due to its size and material characteristics, need to be addressed. In this article, we suggest possible solutions. We fabricated silicon nanowire using a top-down and low cost micromachining method, and evaluate the sensing of molecules after transfer and surface modifications. Our newly designed method can be used to attach highly ordered nanowires to various substrates, to form a nanowire array device, which needs to follow a series of repetitive steps in conventional fabrication technology based on a vapor-liquid-solid (VLS method. For evaluation, we demonstrated that our newly fabricated silicon nanowire arrays could detect pH changes as well as streptavidin-biotin binding events. As well as the initial proof-of-principle studies, C-reactive protein binding was measured: electrical signals were changed in a linear fashion with the concentration (1 fM to 1 nM in PBS containing 1.37 mM of salts. Finally, to address the effects of Debye length, silicon nanowires coupled with antigen proteins underwent electrical signal changes as the salt concentration changed.Keywords: silicon nanowire array, C-reactive protein, vapor-liquid-solid method

    Full Text Available Objective: To study the anti-inflammatory activity of fluoxetine and escitalopram in newly diagnosed patients of depression and also to evaluate the association between depression and inflammation. Materials and Methods: Ninety-eight newly diagnosed patients of depression were recruited as cases. From these, 48 had started treatment with fluoxetine (20 mg/day and 50 had started treatment with escitalopram (20 mg/day. After 2 months of treatment of these patients, Hamilton rating scale for depression (HRSD scale, C-reactive protein (CRP, erythrocyte sedimentation rate (ESR and white blood cell (WBC count were measured and compared to their respective baseline values before starting treatment. One hundred healthy volunteers were recruited as controls and their baseline of CRP, ESR and WBC count were measured and compared with their respective baseline values of cases. Severity of depression was measured by HRSD scale and anti-inflammatory activity was measured by reduction CRP, ESR and WBC count. Results: On baseline comparison between cases and controls, there were significant increases in the levels of CRP (P = 0.014, ESR (P = 0.023 and WBC count (P = 0.020 in cases. In fluoxetine (20 mg/day treatment group, there was a significant reduction in the levels of CRP (P = 0.046, ESR (P = 0.043 and WBC count (P = 0.021 after 2 months of treatment but no significant reduction in HRSD scale (P = 0.190. Similarly, in escitalopram treatment group, there was a significant reduction in CRP (P = 0.041, ESR (P = 0.030 and WBC count (P = 0.017 after 2 months of treatment but no significant reduction in HRSD scale (P = 0.169. Conclusion: In newly diagnosed patients of depression, inflammatory markers such as CRP, ESR and WBC count were significantly raised and Selective serotonin reuptake inhibitors SSRIs such as fluoxetine and escitalopram reduced them independent of their antidepressant effect. So, SSRIs have some anti-inflammatory activity independent of

However, traditional IFAs are commonly qualitative or semi-quantitative and are very limited for the efficient testing of samples in field diagnostics. Here, we overcome these limitations by developing a quantum dots (QDs-based fluorescent IFA for the quantitative detection of C-reactive proteins (CRP. CRP, the well-known diagnostic marker for acute viral and bacterial infections, was used as a model analyte to demonstrate performance and sensitivity of our developed QDs-based IFA. QDs capped with both polyethylene glycol (PEG and glutathione were used as fluorescent labels for our IFAs. The presence of the surface PEG layer, which reduced the non-specific protein interactions, in conjunction with the inherent optical properties of QDs, resulted in lower background signal, increased sensitivity, and ability to detect CRP down to 0.79 mg/L with only 5 µL serum sample. In addition, the developed assay is simple, fast and can quantitatively detect CRP with a detection limit up to 200 mg/L. Clinical test results of our QD-based IFA are well correlated with the traditional latex enhance immune-agglutination aggregation. The proposed QD-based fluorescent IFA is very promising, and potentially will be adopted for multiplexed immunoassay and in field point-of-care test.Keywords: C-reactive proteins, point-of-care test, Glutathione capped QDs, PEGylation

  13. C-reactive protein reacts with the U1 small nuclear ribonucleoprotein

    International Nuclear Information System (INIS)

    C-reactive protein (CRP) was found to produce a small, discrete, speckled fluorescence pattern in the nucleus of HEp-2 cells. Double staining with anti-RNP serum and CRP produced very similar staining patterns. By counterimmunoelectrophoresis CRP was bound to extractable nuclear antigens found in rabbit thymus extract. The reactive components of the extract were only partially sensitive to treatment with RNase. CRP immunoprecipitated the U1 RNA species from [32P]labeled HeLa cells and the protein bands of the Sm/RNP complex from [35S]-methionine-labeled HeLa cells. By blotting, CRP bound to several discrete bands in a calcium-dependent, PC-inhibitable manner. Two of the bands comigrated with the 70K protein band associated with the U1 snRNP, and its major breakdown product. Binding to these bands was inhibited by both EDTA and PC indicating that CRP binds these proteins through the PC-binding site. Binding to the 70K protein of the U1 snRNP was confirmed by reactivity with the recombinant 70K protein in a dot blot. These findings indicate the CRP binds to the U1-RNP snRNP particle. Considering the ability of CRP to inhibit antibody responses to its ligands and its ability to activate C and promote phagocytosis it is suggested that CRP may play a role in the regulation of autoantibody responses to nuclear Ag

    A quick wireless label-free detection of disease-related C-reactive proteins (CRPs) using a 200-microm-long microelectromechanical systems (MEMS) microcantilever housed in a 7 x 7 mm(2) reaction chamber with a safe reusable feature is reported. The assay time ranges from about 30 min to 3 h, depending on accuracy. The deflection of the microcantilever due to specific CRP-antiCRP binding is detected using a position-sensitive detector. The converted bio-signal is transmitted by a custom designed wireless amplitude-shift-keying (ASK) transceiver IC fabricated in a 0.18 microm CMOS process. CRP concentrations from 1 microg/mL to 500 microg/mL can be detected. A 0.2-Hz 1-V ac signal instead of traditional bases/acids is applied to the bio-MEMS sensor to unbind the CRP from the microcantilever for reusability. PMID:19342331

    Fluorescence has been extensively employed in the area of diagnostic immunoassays. A significant enhancement of fluorescence can be achieved when noble metal nanoparticles are placed in close proximity to fluorophores. This effect, referred to as metal-enhanced fluorescence (MEF), has the potential to produce immunoassays with a high sensitivity and a low limit of detection (LOD). In this study, we investigate the fluorescence enhancement effect of two different nanoparticle systems, large spherical silver nanoparticles (AgNPs) and gold edge-coated triangular silver nanoplates, and both systems were evaluated for MEF. The extinction properties and electric field enhancement of both systems were modeled, and the optimum system, spherical AgNPs, was used in a sandwich immunoassay for human C-reactive protein with a red fluorescent dye label. A significant enhancement in the fluorescence was observed, which corresponded to an LOD improvement of ∼19-fold compared to a control assay without AgNPs.

    Full Text Available Besides the typical short-lived fluorescence with decay times in the nanosecond range, colloidal II/VI semiconductor nanoparticles dispersed in buffer also possess a long-lived fluorescence component with decay times in the microsecond range. Here, the signal intensity of the long-lived luminescence at microsecond range is shown to increase 1,000-fold for CdTe nanoparticles in PBS buffer. This long-lived fluorescence can be conveniently employed for time-gated fluorescence detection, which allows for improved signal-to-noise ratio and thus the use of low concentrations of nanoparticles. The detection principle is demonstrated with a time-resolved fluorescence immunoassay for the detection of C-reactive protein (CRP using CdSe-ZnS nanoparticles and green light excitation.

    Full Text Available Background/Aim. Injury-induced anergy is one of the key factors contributing to trauma victims' high susceptibility to sepsis. This group of patients is mostly of young age and it is therefore essential to be able to predict as accurately as possible the development of septic complications, so appropriate treatment could be provided. The aim of this study was to assess kinetics of interleukin (IL -6 and -10, phospholipase A2- II and C-reactive protein (CRP in severely traumatized patients and explore the possibilities for early detection of potentially septic patients. Methods. This prospective study included 65 traumatized patients with injury severity score (ISS > 18, requiring treatment at surgical intensive care units, divided into two groups: 24 patients without sepsis and 41 patients with sepsis. C-reactive protein, IL-6 and -10 and phospholipase A2 group II, were determined within the first 24 hours, and on the second, third and seventh day of hospitalization. Results. Mean values of IL-6 and phospholipase A2-II in the patients with and without sepsis did not show a statistically significant difference on any assessed time points. In the septic patients with ISS 29-35 and > 35 on the days two and seven a statistically significantly lower level of IL-10 was found, compared with those without sepsis and with the same ISS. C-reactive protein levels were significantly higher in septic patients with ISS 18-28 on the first day. On the second, third and seventh day CRP levels were significantly lower in the groups of septic patients with ISS 29-35 and > 35, than in those with the same ISS but without sepsis. Conclusion. Mean levels of CRP on the first day after the injury may be useful predictor of sepsis development in traumatized patients with ISS score 18-28. Mean levels of CRP on the days two, three and seven after the injury may be a useful predictor of sepsis development in traumatized patients with ISS score more than 28. Mean levels of

    In the last decade, saliva has been advocated as a non-invasive alternative to blood as a diagnostic fluid. However, use of saliva has been hindered by the inadequate sensitivity of current methods to detect the lower salivary concentrations of many constituents compared to serum. Furthermore, developments in the areas related to lab-on-a-chip systems for saliva-based point of care diagnostics are complicated by the high viscosity and heterogeneous properties associated with this diagnostic fluid. The biomarker C-reactive protein (CRP) is an acute phase reactant and a well-accepted indicator of inflammation. Numerous clinical studies have established elevated serum CRP as a strong, independent risk factor for the development of cardiovascular disease (CVD). CVD has also been associated with oral infections (i.e. periodontal diseases) and there is evidence that systemic CRP may be a link between the two. Clinical measurements of CRP in serum are currently performed with "high sensitivity" CRP (hsCRP) enzyme-linked immunosorbent assay (ELISA) tests that lack the sensitivity for the detection of this important biomarker in saliva. Because measurement of salivary CRP may represent a novel approach for diagnosing and monitoring chronic inflammatory disease, including CVD and periodontal diseases, the objective of this study was to apply an ultra-sensitive microchip assay system for the measurement of CRP in human saliva. Here, we describe this novel lab-on-a-chip system in its first application for the measurement of CRP in saliva and demonstrate its advantages over the traditional ELISA method. The increased sensitivity of the microchip system (10 pg ml(-1) of CRP with 1000-fold dilution of saliva sample) is attributed to its inherent increased signal to noise ratio, resulting from the higher bead surface area available for antigen/antibody interactions and the high stringency washes associated with this approach. Finally, the microchip assay system was utilized in

    Full Text Available BACKGROUND: Conventional C-reactive protein assays have been used to detect or guide the treatment of acute sepsis. The objective of this study was to determine the association between elevated baseline high-sensitivity C-reactive protein (hsCRP and the risk of future sepsis events. METHODS: We studied data from 30,239 community dwelling, black and white individuals, age ≥45 years old enrolled in the REasons for Geographic and Racial Differences in Stroke (REGARDS cohort. Baseline hsCRP and participant characteristics were determined at the start of the study. We identified sepsis events through review of hospital records. Elevated hsCRP was defined as values >3.0 mg/L. Using Cox regression, we determined the association between elevated hsCRP and first sepsis event, adjusting for sociodemographic factors (age, sex, race, region, education, income, health behaviors (tobacco and alcohol use, chronic medical conditions (coronary artery disease, diabetes, dyslipidemia, hypertension, chronic kidney disease, chronic lung disease and statin use. RESULTS: Over the mean observation time of 5.7 years (IQR 4.5-7.1, 974 individuals experienced a sepsis event, and 11,447 (37.9% had elevated baseline hsCRP (>3.0 mg/L. Elevated baseline hsCRP was independently associated with subsequent sepsis (adjusted HR 1.56; 95% CI 1.36-1.79, adjusted for sociodemographics, health behaviors, chronic medical conditions and statin use. CONCLUSION: Elevated baseline hsCRP was associated with increased risk of future sepsis events. hsCRP may help to identify individuals at increased risk for sepsis.

    Full Text Available Background: Bronchiolitis is a potentially life-threatening respiratory illness commonly affecting children who are less than two years of age. Patients with viral lower respiratory tract infection are at risk for co-bacterial infection. Aim: The aim of our study was to evaluate the use of C-reactive protein (CRP in predicting bacterial co-infection in patients hospitalized for bronchiolitis and to correlate the results with the use of antibiotics. Patients and Methods: This is a prospective study that included patients diagnosed with bronchiolitis admitted to Makassed General Hospital in Beirut from October 2008 to April 2009. A tracheal aspirate culture was taken from all patients with bronchiolitis on admission to the hospital. Blood was drawn to test C-reactive protein level, white cell count, transaminases level, and blood sugar level. Results: Forty-nine patients were enrolled in the study and were divided into two groups. Group 1 included patients with positive tracheal aspirate culture and Group 2 included those with negative culture. All patients with a CRP level ≥2 mg/dL have had bacterial co-infection. White cell count, transaminases and blood sugar levels were not predictive for bacterial co-infection. The presence of bacterial co-infection increased the length of hospital stay in the first group by 2 days compared to those in the second group. Conclusion: Bacterial co-infection is frequent in infants with moderate to severe bronchiolitis and requires admission. Our data showed that a CRP level greater than 1.1 mg/dL raised suspicion for bacterial co-infection. Thus, a tracheal aspirate should be investigated microbiologically in all hospitalized patients in order to avoid unnecessary antimicrobial therapy and to shorten the duration of the hospital stay.

    BACKGROUND: No prospective studies have examined the role of C-reactive protein (CRP) in late-onset bipolar disorder. AIMS: We tested the hypothesis that elevated levels of CRP are associated cross-sectionally and prospectively with late-onset bipolar disorder, and that such an association possibly...... levels of CRP were associated both cross-sectionally and prospectively with late-onset bipolar disorder. When CRP was on a continuous scale, a doubling in CRP yielded an observational odds ratio for late-onset bipolar disorder of 1.28 (1.08-1.52) with a corresponding causal odds ratio of 4.66 (0.......89-24.3). CONCLUSION: Elevated CRP is associated with increased risk of late-onset bipolar disorder in the general population which was supported by the genetic analysis....

  5. Effects of Antisense Oligonucleotides against C-Reactive Protein on the Development of Atherosclerosis in WHHL Rabbits

    Full Text Available Increased plasma levels of C-reactive protein (CRP are closely associated with cardiovascular diseases, but whether CRP is directly involved in the pathogenesis of atherosclerosis is still under debate. Many controversial and contradictory results using transgenic mice and rabbits have been published but it is also unclear whether CRP lowering can be used for the treatment of atherosclerosis. In the current study, we examined the effects of the rabbit CRP antisense oligonucleotides (ASO on the development of atherosclerosis in WHHL rabbits. CRP ASO treatment led to a significant reduction of plasma CRP levels; however, both aortic and coronary atherosclerotic lesions were not significantly changed compared to those of control WHHL rabbits. These results suggest that inhibition of plasma CRP does not affect the development of atherosclerosis in WHHL rabbits.

    The association between high-sensitivity C-reactive protein and recurrent major adverse cardiovascular events (MACE) in patients with ST-elevation myocardial infarction who undergo primary percutaneous coronary intervention remains controversial. To investigate the potential association between high-sensitivity C-reactive protein and an increased risk of MACE such as death, heart failure, reinfarction, and new revascularization in patients with ST-elevation myocardial infarction treated with primary percutaneous coronary intervention. This prospective cohort study included 300 individuals aged >18 years who were diagnosed with ST-elevation myocardial infarction and underwent primary percutaneous coronary intervention at a tertiary health center. An instrument evaluating clinical variables and the Thrombolysis in Myocardial Infarction (TIMI) and Global Registry of Acute Coronary Events (GRACE) risk scores was used. High-sensitivity C-reactive protein was determined by nephelometry. The patients were followed-up during hospitalization and up to 30 days after infarction for the occurrence of MACE. Student's t, Mann-Whitney, chi-square, and logistic regression tests were used for statistical analyses. P values of ≤0.05 were considered statistically significant. The mean age was 59.76 years, and 69.3% of patients were male. No statistically significant association was observed between high-sensitivity C-reactive protein and recurrent MACE (p = 0.11). However, high-sensitivity C-reactive protein was independently associated with 30-day mortality when adjusted for TIMI [odds ratio (OR), 1.27; 95% confidence interval (CI), 1.07-1.51; p = 0.005] and GRACE (OR, 1.26; 95% CI, 1.06-1.49; p = 0.007) risk scores. Although high-sensitivity C-reactive protein was not predictive of combined major cardiovascular events within 30 days after ST-elevation myocardial infarction in patients who underwent primary angioplasty and stent implantation, it was an independent predictor

    Klaus Tschaikowsky

    Full Text Available INTRODUCTION: To prospectively evaluate the performance of Lipopolysaccharide-Binding Protein (LBP in prediction of hospital mortality and its correlation to C-reactive Protein (CRP, we studied sixty consecutive, postoperative patients with sepsis admitted to the university hospital intensive care unit. MEASUREMENTS AND METHODS: Plasma LBP and CRP were serially measured from day(d1 (onset of sepsis to d14 in parallel with clinical data until d28. Predictive value and correlation of LBP and CRP were analyzed by Receiver Operating Characteristic (ROC curve analysis and Pearson's test, respectively. MAIN RESULTS: LBP and CRP showed the highest levels on d2 or d3 after the onset of sepsis with no significant difference between survivors and nonsurvivors. Only at d7, nonsurvivors had significantly (p = .03 higher levels of CRP than survivors. Accordingly, in ROC analysis, concentration of CRP and LBP on d7 poorly discriminated survivors from nonsurvivors (area under curve = .62 and .55, respectively without significant difference between LBP- and CRP-ROC curves for paired comparison. LBP and CRP plasma levels allocated to quartiles correlated well with each other (r(2 = .95; p = .02. Likewise, changes in plasma concentrations of LBP and CRP from one observation to the next showed a marked concordance as both parameters concomitantly increased or decreased in 76% of all cases. CONCLUSIONS: During the first 14 days of postoperative sepsis, LBP plasma concentrations showed a time course that was very similar to CRP with a high concordance in the pattern of day-to-day changes. Furthermore, like CRP, LBP does not provide a reliable clue for outcome in this setting.

    Objective: To investigate the expression of OX40 ligand(OX40L) on C-reactive protein(CRP)-triggered mouse aorta endothelial cells (MAECs) in vitro. Methods: MAECs from aorta were isolated by digestion with collagenase type Ⅱ. The cell growth was confirmed by morphological characteristics and the immunological marker, factor Ⅷ(or Willebrand factor, vWF). The expression of OX40L by MAECs was detected by RT-PCR and western blot after incubating with 100 μg/ml CRP for 48 hours. Results: Twenty-day cultures of MAECs formed confluent monolayer of a cobblestone pattern. RT-PCR and western blot assay showed that the level of OX40L expression in MAECs receiving CRP treatment was higher than control. Conclusion: A reliable method is described to isolate and propagate MAECs. CRP upregulates OX40L expression in MAECs.

    The C-reactive protein (CRP), first described as a serum component capable of precipitating the C-polysaccharide of pneumococci, is one of the most important proteins because the serum concentration rises in the acute phase reaction. The acute phase reaction is the nonspecific reaction of the body to noxious stimuli of the most varied kinds, such as infections, burns, neoplasms and tissue trauma. The CRP is synthesized in liver parenchymal cells by cytokines which are derived from stimulated leucocytes and released into the circulation. Because of its molecular structure and in synergy with the complement system, it is able to precipitate and/or lyse microorganisms, thereby rendering them harmless. Measurement of the serum CRP concentration can provide important information with respect to the diagnosis and monitoring of treatment. Due to immunosenescence in geriatric patients the synthesis of CRP appears to be limited to inflammatory stimuli; however, this phenomenon does not appear to be of major clinical relevance. Despite the introduction of new parameters of the acute phase reaction, sometimes with better performance, such as interleukin-6, procalcitonin and the soluble endotoxin receptor sCD14, measurement of CRP for diagnosis and treatment monitoring is still justified even in geriatric patients as testing is rapid, economic and nearly ubiquitously available round the clock. Biochemical markers of the acute phase reaction should always be interpreted together with the clinical picture and their specific limitations. PMID:26334841

    Full Text Available Abstract Background This study evaluated the relationship between the G(-866A polymorphism of the uncoupling protein 2 (UCP2 gene and high-sensitivity C reactive protein (hs-CRP plasma levels in diabetic patients. Methods We studied 383 unrelated people with type 2 diabetes aged 40-70 years. Anthropometry, fasting lipids, glucose, HbA1c, and hs-CRP were measured. Participants were genotyped for the G (-866A polymorphism of the uncoupling protein 2 gene. Results Hs-CRP (mg/L increased progressively across the three genotype groups AA, AG, or GG, being respectively 3.0 ± 3.2, 3.6 ± 5.0, and 4.8 ± 5.3 (p for trend = 0.03. Since hs-CRP values were not significantly different between AA and AG genotype, these two groups were pooled for further analyses. Compared to participants with the AA/AG genotypes, homozygotes for the G allele (GG genotype had significantly higher hs-CRP levels (4.8 ± 5.3 vs 3.5 ± 4.7 mg/L, p = 0.01 and a larger proportion (53.9% vs 46.1%, p = 0.013 of elevated hs-CRP (> 2 mg/L. This was not explained by major confounders such as age, gender, BMI, waist circumference, HbA1c, smoking, or medications use which were comparable in the two genotype groups. Conclusions The study shows for the first time, in type 2 diabetic patients, a significant association of hs-CRP levels with the G(-866A polymorphism of UCP2 beyond the effect of major confounders.

  14. C-reactive protein inhibits survivin expression via Akt/mTOR pathway downregulation by PTEN expression in cardiac myocytes.

    Directory of Open Access Journals (Sweden)

    Beom Seob Lee

    Full Text Available C-reactive protein (CRP is one of the most important biomarkers for arteriosclerosis and cardiovascular disease. Recent studies have shown that CRP affects cell cycle and inflammatory process in cardiac myocytes. Survivin is also involved in cardiac myocytes replication and apoptosis. Reduction of survivin expression is associated with less favorable cardiac remodeling in animal models. However, the effect of CRP on survivin expression and its cellular mechanism has not yet been studied. We demonstrated that treatment of CRP resulted in a significant decrease of survivin protein expression in a concentration-dependent manner in cardiac myocytes. The upstream signaling proteins of survivin, such as Akt, mTOR and p70S6K, were also downregulated by CRP treatment. In addition, CRP increased the protein and mRNA levels of PTEN. The siRNA transfection or specific inhibitor treatment for PTEN restored the CRP-induced downregulation of Akt/mTOR/p70S6K pathway and survivin protein expression. Moreover, pretreatment with a specific p53 inhibitor decreased the CRP-induced PTEN expression. ERK-specific inhibitor also blocked the p53 phosphorylation and PTEN expression induced by CRP. Our study provides a novel insight into CRP-induced downregulation of survivin protein expression in cardiac myocytes through mechanisms that involved in downregulation of Akt/mTOR/p70S6K pathway by expression of PTEN.

    2016-03-01

    In the article, a dual-quantum-dots-labeled (dual-QDs-labeled) lateral flow strip (LFS) method was developed for the simultaneous and rapid quantitative detection of procalcitonin (PCT) and C-reactive protein (CRP) in the blood. Two QD-antibody conjugates with different fluorescence emission spectra were produced and sprayed on the LFS to capture PCT and CRP in the blood. Furthermore, a double antibody sandwich method for PCT and, meanwhile, a competitive inhibition method for CRP were employed in the LFS. For PCT and CRP in serum assayed by the dual-QDs-labeled LFS, their detection sensitivities reached 0.1 and 1 ng/mL, respectively, and their linear quantitative detection ranges were from 0.3 to 200 ng/mL and from 50 to 250 μg/mL, respectively. There was little evidence that the PCT and CRP assays would be interfered with each other. The correlations for testing CRP and PCT in clinical samples were 99.75 and 97.02 %, respectively, between the dual-QDs-labeled LFS we developed and commercial methods. The rapid quantification of PCT and CRP on dual-QDs-labeled LFS is of great clinical value to distinguish inflammation, bacterial infection, or viral infection and to provide guidance for the use of antibiotics or other medicines.

    Complement (C) activation is believed to play an adverse role in several chronic degenerative disease processes, including atherosclerosis, myocardial infarction and Alzheimer's disease. We developed several in vitro quantitative assays to evaluate processes which activate C in human serum, and to assess candidates which might block that activation. Binding of C-reactive protein (CRP) to immobilized cell surfaces was used as a tissue-based method of activation, while immunoglobulin G in solution was used as a surrogate antibody method. Activation was assessed by deposition of C fragments on fixed cell surfaces, or by capture of C5b-9 from solution. We observed that several cell lines, including SH-SY5Y, U-937, THP-1 and ECV304, bound CRP and activated C following attachment of cells to a plastic surface by means of air drying. Treatment of human neuroblastoma SH-SY5Y cells with the reactive oxygen intermediates generated by xanthine (Xa) - xanthine oxidase (XaOx) prior to air drying or by hydrogen peroxide solutions after air drying, enhanced C activation, possibly through oxidation of the cell lipid membrane. Several C inhibitors were tested for their effectiveness in blocking these systems. Pentosan polysulphate (PPS), an orally active agent, blocked C activation in the same concentration range of 1-1000 microg/ml as heparin, dextran sulphate, compstatin and fucoidan. PPS may have practical application as a C inhibitor. PMID:12100726

    Full Text Available Background/Aims: This study aimed to evaluate the effectiveness of homocysteine and C-reactive protein (CRP as potential markers for chronic kidney disease (CKD in adults in Taiwan, and to identify associations between these factors and CKD, stratifying by gender. Methods: This cross-sectional study analyzed multi-center data retrospectively. Data were collected from 22,043 adult Taiwanese at Chang-Gung Memorial Hospital from 2005 to 2011. Smoking/drinking history, personal medical/medication history, pregnancy, fasting times as well as laboratory parameters, including homocysteine and CRP were measured and analyzed. Results: Significant differences were observed between four homocysteine and CRP quartiles in eGFR and CKD. For males, only one model showed significant associations between plasma homocysteine and CKD, while in females, all three models showed significant associations with CKD. On the contrary, the gender difference in the case of CRP was opposite. Combined homocysteine and CRP were associated with CKD in males but not in females. Conclusion: Among Taiwanese adults, plasma homocysteine is associated with CKD in females and plasma hsCRP is associated with CKD in males. High hsCRP/high homocysteine is associated with elevated CKD risk in male. Our results suggest that homocysteine and hsCRP may be useful surrogate markers for evaluating CKD risk in adults.

    Current diagnostic immunotechnologies are universally based on the measurement of the bound label-antibody fraction in direct binding or sandwich-assay type approaches with various detection techniques (e.g. enzyme-linked immunosorbent assay or ELISA) on solid stationary phase surface. Here an alternative reciprocal approach is presented based on the detection of the non-bound fraction of nanoparticle-labelled antibodies using microparticles as solid support. The advantage of detecting the non-bound fraction of the labelled antibody instead of the bound fraction is the high dynamics and the suggested increased flexibility in the selection of the detection mode. No actual washing steps are required as the bound and non-bound fractions of the detection nanoparticle label are separated using physical separation rather than consecutive washing repeats. The quantitative proof-of-concept set-up was demonstrated through blood-based detection of C-reactive protein (CRP). A blood sample containing CRP was diluted 1/50 and measured in 15-min resulting in a linear response at a range from 1 to 30μg/ml. The lowest limit of detection was below 0.03μg/ml and the assay coefficient of variation ranged from 0.3 to 9%. The nanoparticle-based residual label detection outperformed the corresponding molecular label method providing wider applicability with nearly an order of magnitude higher signal-to-background ratio for novel assay configurations in clinical diagnostics practices.

    Laboratory evidence suggests that certain specialty dietary supplements have antiinflammatory properties, though evidence in humans remains limited. Data on a nationally representative sample of 9,947 adults from the 1999-2004 cycles of the National Health and Nutrition Examination Survey were used to assess the associations between specialty supplement use and inflammation, as measured by serum high-sensitivity C-reactive protein (hs-CRP) concentration. Using survey-weighted multivariate linear regression, significant reductions in hs-CRP concentrations were associated with regular use of glucosamine (17%, 95% confidence interval (CI): 7, 26), chondroitin (22%, 95% CI: 8, 33), and fish oil (16%, 95% CI: 0.3, 29). No associations were observed between hs-CRP concentration and regular use of supplements containing methylsulfonylmethane, garlic, ginkgo biloba, saw palmetto, or pycnogenol. These results suggest that glucosamine and chondroitin supplements are associated with reduced inflammation in humans and provide further evidence to support an inverse association between use of fish oil supplements and inflammation. It is important to further investigate the potential antiinflammatory role of these supplements, as there is a need to identify safe and effective ways to reduce inflammation and the burden of inflammation-related diseases such as cancer and cardiovascular disease.

  3. Two-layer reflectometric interference spectroscopy-based immunosensing for C-reactive protein

    International Nuclear Information System (INIS)

    We report on dual interference layers for use in reflectometric interference spectroscopy (RIfS)-based immunosensing. The layers consist of (a) an antibody-embedded organic/inorganic hybrid titanium dioxide (TiO2) layer (∼60 nm thick) as a sensitive layer, and (b) a TiO2 layer (∼110 nm thick) as an interference base layer placed on a silicone substrate by liquid phase deposition. A monoclonal antibody against C-reactive protein (anti-CRP) was co-embedded with poly(L-lysine) as an organic binder during deposition of the TiO2 layer. The optical properties of layer with the antibody were optimized to achieve high sensitivity. Atomic force microscopy images of the sensor surface showed it to consist of a mesoporous structure with nano-scale unevenness. The binding of CRP to the sensor chips was monitored by RIfS, and CRP was repeatedly detected by this biosensor with a detection limit of ∼60 ng mL−1. We presume that this two-layer method has a wide scope in that various kinds of biochips can be constructed for use in label-free optical biosensing. (author)

    2013-02-01

    Full Text Available Background:Raised concentrations of C-reactive protein (CRP have been reported to be strongly related to an adverse long term prognosis in patients with acute myocardial infarction (AMI. However, adjustments for clinical variables as well as interaction between variables have been incomplete. The aims of this study were to examine the predictive value of baseline concentrations of CRP for mortality after adjustment for important clinical variables and to compare the clinical usefulness of CRP with easily available clinical variables in the prediction of long term survival.Methods:Five hundred and thirty-one patients with AMI were included. A blood sample for CRP was obtained on admission. All patients were followed for a minimum of two years and death of any cause was recorded as the study end point.Results:In logistic regression analysis, the interaction term Age by Killip class > 1, the variable glomerular filtration rate as well as the interaction term Age by Atrial fibrillation were retained. The resulting model correctly predicted death or not in 81% of the patients. CRP did not contribute to the final model.Conclusions:CRP does not independently predict long-term mortality after an AMI after adjustments for clinical variables and interaction. CRP has no value beyond clinical variables in predicting death after AMI.

    In the article, a dual-quantum-dots-labeled (dual-QDs-labeled) lateral flow strip (LFS) method was developed for the simultaneous and rapid quantitative detection of procalcitonin (PCT) and C-reactive protein (CRP) in the blood. Two QD-antibody conjugates with different fluorescence emission spectra were produced and sprayed on the LFS to capture PCT and CRP in the blood. Furthermore, a double antibody sandwich method for PCT and, meanwhile, a competitive inhibition method for CRP were employed in the LFS. For PCT and CRP in serum assayed by the dual-QDs-labeled LFS, their detection sensitivities reached 0.1 and 1 ng/mL, respectively, and their linear quantitative detection ranges were from 0.3 to 200 ng/mL and from 50 to 250 μg/mL, respectively. There was little evidence that the PCT and CRP assays would be interfered with each other. The correlations for testing CRP and PCT in clinical samples were 99.75 and 97.02 %, respectively, between the dual-QDs-labeled LFS we developed and commercial methods. The rapid quantification of PCT and CRP on dual-QDs-labeled LFS is of great clinical value to distinguish inflammation, bacterial infection, or viral infection and to provide guidance for the use of antibiotics or other medicines.

    Full Text Available Introduction: The present study was conducted to assess the effect of BCAA supplementation on serum C - reactive protein, after acute resistance exercise in soccer players.Methods: 20 soccer players in a randomized one-blind design completed in random 3 sets of 8-10 repetitions of 7 exercises. Subjects were randomized to two ten-member groups and consumed 200 mg. kg-1 BW of either BCAA or dextrin (placebo 30 minutes prior to exercise. To identify HS-CRP, venous blood samples were obtained 30 min prior to and immediately following exercise and at 1 hr, 2 hrs, 24hrs post exercise. Data were analyzed using 2-way repeated measure ANOVA and Bonferroni post hoc test. Results: Baseline serum values for Hs-CRP were not statistically different between groups in the 30 minutes before the exercise test (P>0.05. However there were significant increases (P<0.05 between the pre exercise and post exercise values for Hs-CRP from 24 hrs posttest, (P<0.05(. Importantly, the BCAA supplementation significantly reduced this Hs-CRP 24hrs post-test (P<0.05(.Conclusion: These results indicate that supplementary BCAA decreased serum concentrations of the inflammation biomarker Hs-CRP following resistance exercise. This observation suggests that BCAA supplementation may reduce the inflammation biomarker associated with resistance exercise.

    BACKGROUND: The concentration of C-reactive protein (CRP) in otherwise healthy subjects has been shown to predict future risk of myocardial infarction and stroke. CRP is synthesized by the liver in response to interleukin-6, the serum concentration of which is subject to diurnal variation. METHODS: To examine the existence of a time-of-day effect for baseline CRP values, we determined CRP concentrations in hourly blood samples drawn from healthy subjects (10 males, 3 females; age range, 21-35 years) during a baseline day in a controlled environment (8 h of nighttime sleep). RESULTS: Overall CRP concentrations were low, with only three subjects having CRP concentrations >2 mg/L. Comparison of raw data showed stability of CRP concentrations throughout the 24 h studied. When compared with cutoff values of CRP quintile derived from population-based studies, misclassification of greater than one quintile did not occur as a result of diurnal variation in any of the subjects studied. Nonparametric ANOVA comparing different time points showed no significant differences for both raw and z-transformed data. Analysis for rhythmic diurnal variation using a method fitting a cosine curve to the group data was negative. CONCLUSIONS: Our data show that baseline CRP concentrations are not subject to time-of-day variation and thus help to explain why CRP concentrations are a better predictor of vascular risk than interleukin-6. Determination of CRP for cardiovascular risk prediction may be performed without concern for diurnal variation.

    Full Text Available Overall and cardiovascular mortality are significantly higher in hemodialysis patients with elevated C-reactive protein (CRP. The aim of study was to determine whether CRP, low albumin and troponin are markers of overall and cardiovascular mortality in hemodialysis patients. 138 stable hemodialysis patients were divided into 2 groups n= 66 patients with coronary disease equivalent (known coronary or peripheral vascular disease or diabetes mellitus and n= 72 patients without it. The two groups were then stratified by biomarkers [cardiac troponin T and Albumin and highly sensitive CRP (hs-CRP] and followed for 30 months. The primary outcome was all causes mortality. Patients with coronary disease equivalents had 3.5 fold greater annual mortality compared to controls (24%% vs 6.9%, P value = 0.005. Elevated troponin T had a further increase in the risk for death while hs-CRP and low albumin were not associated with risk of death In conclusion, circu-lating cardiac troponin-T was associated with poor prognosis especially in hemodialysis patients with coronary risk factors.

    Despite substantial differences in ethnicities, habits, cultures, the prevalence of traditional cardiovascular risk factors and affordable therapies, atherosclerosis remains the major cause of death in developing and developed countries. However, irrespective of these differences, inflammation is currently recognized as the common pathway for the major complications of atherosclerosis, stroke, and ischemic heart disease. A PubMed search was conducted for "high-sensitivity C-reactive protein" (hs-CRP) in combination with the terms race, ethnicity, gender, prevalence, geographic, epidemiology, cardiovascular, obesity, diabetes, hypertension, cholesterol, smoking, ischemic heart disease, stroke, and mortality. This review includes the articles that pertained to the topic and additional articles identified from the reference lists of relevant publications. This review describes the marked differences in cardiovascular mortality across countries and ethnicities, which may be attributed to inequalities in the prevalence of the classic risk factors and the stage of cardiovascular epidemiological transition. However, hs-CRP appears to contribute to the prognostic information regarding cardiovascular risk and mortality even after multiple adjustments. Considering the perception of cardiovascular disease as an inflammatory disease, the more widespread use of hs-CRP appears to represent a valid tool to identify people at risk, independent of their ancestry or geographic region. In conclusion, this review reports that the complications associated with vulnerable atherosclerotic plaques are triggered by the major mechanisms of dyslipidemia and inflammation; whereas both mechanisms are influenced by classic risk factors, hs-CRP contributes additional information regarding cardiovascular events and mortality.

    Full Text Available Abstract Objective Insulin resistance (IR, a reduced physiological response of peripheral tissues to the action of insulin, is one of the major causes of type 2 diabetes. We sought to evaluate the relationship between serum C-reactive protein (CRP, a marker of systemic inflammation, and prevalence of IR among Peruvian adults. Methods This population based study of 1,525 individuals (569 men and 956 women; mean age 39 years old was conducted among residents in Lima and Callao, Peru. Fasting plasma glucose, insulin, and CRP concentrations were measured using standard approaches. Insulin resistance was assessed using the homeostasis model (HOMA-IR. Categories of CRP were defined by the following tertiles: 2.53 mg/l. Logistic regression procedures were employed to estimate odds ratios (OR and 95% confidence intervals (CI. Results Elevated CRP were significantly associated with increased mean fasting insulin and mean HOMA-IR concentrations (p 2.53 mg/l (upper tertile had a 2.18-fold increased risk of IR (OR = 2.18 95% CI 1.51-3.16 as compared with those in the lowest tertile ( Conclusion Our observations among Peruvians suggest that chronic systemic inflammation, as evidenced by elevated CRP, may be of etiologic importance in insulin resistance and diabetes.

    Full Text Available Aim: Early diagnosis of sepsis in the neonate is often difficult because symptoms and signs are usually non-specific. A study was conducted to evaluate C-reactive protein (CRP as a screening tool for neonatal sepsis. Method: The prospective observational study was conducted at NICU, V. S. Hospital, Ahmedabad from January 2008 to June 2009. 75 neonates were included with the age group of first 28days (4week of life (infant age in study, all of which were suspected to have sepsis in clinical settings. All peripheral smear of neonate stained with Giemsa stain were reviewed .CRP performed by semi quantitative latex agglutination method. Positive cultures were the “gold standard” against which the performance of CRP , abnormal white blood cell counts (WBC & absolute neutrophil counts (ANC were compared. Results: Among 75 septic screens, 39 (52% patients had positive cultures. The sensitivity and specificity of CRP 0.6 mg/dL was 92.30% and 85.71% respectively. Abnormal platelet count had the lowest specificity(45% and sensitivity(23.07% among them. Conclusion: CRP assay using semi quantitative latex agglutination method is a valuable adjunct in screening for neonatal sepsis, complementing clinical decision-making.

    C-reactive protein (CRP) produced by the liver is one of the most characteristic acute-phase proteins. It has been suggested that the level of CRP in human serum may be a significant tool of detecting risks of developing cardiovascular disease and atherosclerosis. Here we propose an advanced plasmonic surface plasmon resonance (SPR) bioassay with Au nanoparticles embedded in the dielectric film that demonstrates a 10X improvement in resolution compared to the conventional SPR biosensor. The co-sputtered film was modified with (3-Aminopropyl)triethoxysilane to sequentially immobilize protein G, monoclonal anti-CRP antibody (C8), and human serum albumins (HSA). After blocked by ethanolamine, the sensor was used to detect CRP. Using this extremely sensitive biochip, the lowest reliable concentration of CRP without any exterior labeling is simplified to human physiological level. The novel assay has the latent capability of not only eliminating the disturbances coming from serum proteins resulting in false signals, but is also able to be applied in rapid and label-free clinical detections of CRP with large improved sensitivity.

  3. Univariate and multivariate analysis of risk factors for severe clostridium difficile-associated diarrhoea Importance of co-morbidity and serum C-reactive protein

    Institute of Scientific and Technical Information of China (English)

    2008-01-01

    AIM: To investigate risk factors for severe clostridium difficile associated diarrhoea (CDAD) in hospitalised patients. METHODS: We analysed risk factors for severe CDAD (associated with systemic signs of hypovolemia) in 124 hospitalised patients by retrospective chart review. RESULTS: Severe CDAD was present in 27 patients (22%). Statistical analysis showed a significant association with a higher 30-d mortality (33% vs 4%, P < 0.001) and a higher proportion of longer hospital stay exceeding 14 d (74% vs 52%, P = 0.048). Charlson co-morbidity score (OR 1.29 for 1 point increment, P < 0.05) and serum C-reactive protein at diagnosis (OR 1.15 for 10 mg/L increment, P <0.001) were independent predictors of severe CDAD. CONCLUSION: Patients with a severe level of co- morbidity and high serum C-reactive protein levels at the time of diagnosis should receive particular attention.

    2009-01-01

    OBJECTIVE: To test whether depressive symptoms are related to subsequent C-reactive protein (CRP) levels and/or whether CRP levels are related to subsequent depressive symptoms in mid-life women. METHODS: Women enrolled in the Study of Women's Health Across the Nation (SWAN) were followed for seven years and had measures of CES-Depression scores and CRP seven times during the follow-up period. Women were pre- or early peri-menopausal at study entry and were of Caucasian, African American, Hispanic, Japanese, or Chinese race/ethnicity. Analyses were restricted to initially healthy women. RESULTS: Longitudinal mixed linear regression models adjusting for age, race, site, time between exams, and outcome variable at year X showed that higher CES-D scores predicted higher subsequent CRP levels and vice versa over a 7-year period. Full multivariate models adjusting for body mass index, physical activity, medications, health conditions, and other covariates showed that higher CRP levels at year X predicted higher CES-D scores at year X+1, p = 0.03. Higher depressive symptoms predicted higher subsequent CRP levels at marginally significant levels, p=0.10. CONCLUSIONS: Higher CRP levels led to higher subsequent depressive symptoms, albeit the effect was small. The study demonstrates the importance of considering bi-directional relationships for depression and other psychosocial factors and risk for heart disease. PMID:19683568

  5. C-reactive protein in patients with acute coronary syndrome: association with coronary markers, lipid profile and markers of coagulation

    International Nuclear Information System (INIS)

    To determine levels of C-reactive protein (CRP) and its association with coronary markers, lipid profile and markers of coagulation in patients of acute coronary syndrome (ACS). The study was conducted at Shifa college of Medicine and Shifa international hospital for a period of one year (November 2005-December 2006). Patients and Methods: Sixty nine age matched controls and 133 consecutive patients of ACS were included in the study. CRP were measured by immunoturbidometric method, MB fraction of creatine kinase (CK-MB) and Troponin-1 by micro-particle enzyme immunoassay, lipid levels by Colorimetric Enzymatic methods, platelets by celldyn and coagulation markers were measured by CA-50 Sysmax. At admission mean CRP levels, cardiac biomarkers, lipid profile and coagulation markers were significantly increased in patients of ACS versus controls. Within the patients of ACS the mean levels of CRP, CK-MB, Trop I, prothrombin time (PT) and activated partial thromboplastin time (Am) were significantly raised in patients with ST - elevation myocardial infarction (STEMI) and non STEMI (NSTEMI) versus patients of unstable angina (VA). Association between CRP levels and coronary markers, coagulation markers and lipid profile was found to be non significant. The CRP levels were increased in patients with ACS as compared to controls. The CRP levels were insignificantly correlated with coronary markers (CK-MB, Trop I), coagulation markers (platelet count, PT, Am), and lipid profile (cholesterol, triglyceride, HDL and LDL cholesterol) in patients with ACS.

    Maternal pregnancy levels of the inflammatory marker C-reactive protein (CRP) has been previously associated with autism spectrum disorder (ASD) in the offspring. We conducted a population-based nested case-control study with 500 children with ASD, 235 with developmental delay (DD) and 580 general population (GP) controls to further investigate whether elevated CRP during pregnancy increases the risk of ASD. Maternal CRP concentration was measured in archived serum collected during 15-19 weeks of pregnancy and genome-wide single-nucleotide polymorphism (SNP) data were generated. The levels of CRP were compared between ASD vs GP and DD vs GP. The genetic associations with CRP were assessed via linear regression. Maternal CRP levels in mid-pregnancy were lower in mothers of ASD compared with controls. The maternal CRP levels in the upper third and fourth quartiles were associated with a 45 and 44% decreased risk of ASD, respectively. Two SNPs at the CRP locus showed strong association with CRP levels but they were not associated with ASD. No difference was found between maternal CRP levels of DD and controls. The reasons for the lower levels of CRP in mothers of ASD are not known with certainty but may be related to alterations in the immune response to infectious agents. The biological mechanisms underlying this association remain to be clarified. PMID:27093065

    Full Text Available Abstract Background Atherosclerosis underlies the major pathophysiological mechanisms of coronary heart disease (CHD, and inflammation contributes to all phases of atherosclerosis. C-reactive protein (CRP, a sensitive, but nonspecific marker of inflammation has been shown to play proatherogenic roles in the process of atherosclerosis. Our previous report showed that rs2794521 (-717A>G, located in the promoter of the CRP gene, was independently associated with CHD in Chinese subjects. In the present study, we tried to investigate the biological significance of this genetic variation in vitro. Methods The influence of G to A substitution at the site of rs2794521 on the transcriptional activity of the promoter of the CRP gene was assessed by luciferase reporter assay, and protein binding to the site of rs2794521 was detected by EMSA assay. Results The G to A exchange at the site of rs2794521 resulted in an increased transcriptional activity of the promoter of CRP gene, and glucocorticoid receptor (GR protein factor bound drastically differently to the A and G alleles at the site of rs2794521. Conclusion These results provided functional evidence supporting the association of the SNP rs2794521 of the CRP gene with CHD probably through regulating the expression level of CRP by different variations of rs2794521.

  11. High-affinity RNA aptamers to C-reactive protein (CRP): newly developed pre-elution methods for aptamer selection

    International Nuclear Information System (INIS)

    We have developed a modified SELEX (systematic evolution of ligands by exponential enrichment) method to obtain RNA aptamers with high affinity to C-reactive protein (CRP). CRP is a clinical biomarker present in plasma, the level of which increases in response to infections and noninfectious inflammation. The CRP level is also an important prognostic indicator in patients with several syndromes. At present, CRP content in blood is measured immunochemically using antibodies. To develop a more sensitive method using RNA aptamers, we have attempted to obtain high-affinity RNA aptamers to CRP. We succeeded in obtaining an RNA aptamer with high affinity to CRP using a CRP-immobilized Sepharose column and pre-elution procedure. Pre-elution is a method that removes the weak binding portion from a selected RNA population by washing for a short time with buffer containing CRP. By surface plasmon-resonance (SPR) analysis, the affinity constant of this aptamer for CRP was calculated to be KD = 2.25x10-9 (M). The secondary structure, contact sites with CRP protein, and application of this aptamer will be described.

    High sensitivity C-reactive protein (hs-CRP) is commonly used in clinical practice to assess cardiovascular risk. However, a correlation has not yet been established between the absolute levels of peripheral and central hs-CRP. To assess the correlation between serum hs-CRP levels (mg/L) in a peripheral vein in the left forearm (LFPV) with those in the coronary sinus (CS) of patients with coronary artery disease (CAD) and a diagnosis of stable angina (SA) or unstable angina (UA). This observational, descriptive, and cross-sectional study was conducted at the Instituto do Coração, Hospital das Clinicas, Faculdade de Medicina, Universidade de São Paulo, and at the Hospital Beneficência Portuguesa de Sao Paulo, where CAD patients referred to the hospital for coronary angiography were evaluated. Forty patients with CAD (20 with SA and 20 with UA) were included in the study. Blood samples from LFPV and CS were collected before coronary angiography. Furthermore, analysis of the correlation between serum levels of hs-CRP in LFPV versus CS showed a strong linear correlation for both SA (r = 0.993, p < 0.001) and UA (r = 0.976, p < 0.001) and for the entire sample (r = 0.985, p < 0.001). Our data suggest a strong linear correlation between hs-CRP levels in LFPV versus CS in patients with SA and UA.

    Aim To investigate the association between serum C-reactive protein (CRP) levels and coronary collateral circulation (CCC) in Chinese patients with angiography-proven ≥95% coronary stenosis. Methods In this study, 1158 patients with angiography-proven ≥95% occlusion in ≥1 major epicardial coronary artery were enrolled, and then classified into two groups: poor CCC (Rentrop grades 0-1) and good CCC (Rentrop grades 2-3). CRP levels were grouped using the following two models: Model 1 discretized CRP group with 33.33% and 66.66% as the critical values and Model 2 with 1.0 and 3.0 mg/L as the cut off values. Results There were significant differences in serum CRP levels between the two groups (5.76 ± 3.45 vs. 3.49 ± 2.44 mg/L, respectively; p grade 1 anterograde-flow, the relationship between CRP concentrations and angiographically visible coronary collateral (CC) was assessed. Our data indicated that elevated CRP associated with a significant impairment in CC development, and might supply a useful biomarker in clinical applications. PMID:26790524

    Obese subjects have higher circulating levels of C-reactive protein (CRP) than normal subjects, and it has been shown that CRP per se may contribute to atherogenesis. The mechanism linking increased fat mass with high CRP levels has not been exhaustively explained. It has been suggested that adipose tissue-produced cytokines, including interleukin-6, tumor necrosis factor-alpha, and interleukin-1beta, represent the causal link between increased body fat and high CRP levels. It has been hypothesized that the hormone leptin, released by fat cells, may stimulate CRP production independent of cytokines. This study measured circulating leptin, CRP, interleukin-6, tumor necrosis factor-alpha, interleukin-1beta, and interleukin-8 in 946 community-dwelling older subjects (398 men, 548 women; age range 65 to 102 years) enrolled in a large population-based study. Confounders included demographics, functional, cognitive and affective status, diet and lifestyle, body composition, drugs, and chronic diseases. A direct association was found between leptin and CRP (p = 0.004), independent of cytokines and other possible confounders. The association was stronger in younger than in older subjects but was not influenced by gender or body mass index. In conclusion, these findings suggest that leptin may directly stimulate the production of CRP independent of fat-cell produced cytokines in older adults. PMID:16188530

    Metabolic syndrome (MS) is a core set of disorders, including abdominal obesity, dyslipidemia, hypertension and hypertriglyceridemia that together predict the development of diabetes type 2 and cardiovascular disease. This study investigated the relationship between liver enzyme levels and high-sensitivity C-reactive protein (hs-CRP) in subjects with and without MS. Alanine-aminotransferase (ALAT), aspartate-aminotransferase (ASAT), γ-glutamyl transferase (GGT) and hs-CRP were measured in 510 subjects, aged 40 to 65 years old. Patients were selected from 1007 subjects from the Research Program for Cardiovascular Disease Risk Factors in Talca, Chile. Results showed that women with MS presented higher liver enzyme levels than those who did not have MS. This was not observed in male patients for the enzymes ALAT and ASAT. However, GGT and hs-PCR levels were higher in male and female patients with MS than in those without MS. In conclusion, it is important to search for the presence of MS when diagnosing fatty liver. Moreover, the presence of liver disease in patients with MS should be further investigated. PMID:23136611

    Full Text Available Previous studies have suggested that C-reactive protein (CRP was associated with risk of stroke. There were few studies in Asian population, or on stroke subtypes other than ischemic stroke. We thus investigated the relationship between CRP and the risks of all stroke and its subtypes in a Chinese adult population.In the current study, we included 90,517 Chinese adults free of stroke and myocardial infarction at baseline (June 2006 to October 2007 in analyses. Strokes were classified as ischemic stroke (IS, intracranial heamorrhage (ICH and subarachnoid heamorrhage (SAH. High-sensitivity CRP (hs-CRP were categorized into three groups: 3 mg/L. Cox proportional hazards regression was used to calculate the association between hs-CRP concentrations and all stroke, as well as its subtypes.During a median follow-up time of 49 months, we documented 1,472 incident stroke cases. Of which 1,049 (71.3% were IS, 383 (26.0% were ICH, and 40 (2.7% were SAH. After multivariate adjustment, hs-CRP concentrations ≥1 mg/L were associated with increased risks of all stroke (hs-CRP 1-3 mg/L: hazard ratio (HR 1.17, 95% confidential interval (CI 1.03-1.33; hs-CRP>3 mg/L: HR 1.25, 95% CI 1.07-1.46 and IS (hs-CRP 1-3 mg/L: HR 1.17, 95% CI 1.01-1.36; hs-CRP>3 mg/L: HR 1.33, 95% CI 1.11-1.60, but not with ICH and SAH. Subgroup analyses showed that higher hs-CRP concentration was more prone to be a risk factor for all stroke and IS in non-fatal stroke, male and hypertensive participants.We found that higher hs-CRP concentrations were associated with a higher risk of IS, particularly for non-fatal stroke, male and hypertensive subjects. In contrast, we did not observe significant associations between hs-CRP and ICH/SAH.

    Full Text Available Background/Aim. Inflammation plays a key role in the physiopathology of arteriosclerosis. C-reactive protein (CRP and common carotid artery intima-media thickness are independent predictors of cardiovascular events and diabetes mellitus in apparently healthy men, but relationship between them is not fully elucidated. The aim of the study was to assess the cross-sectional relationship between CRP and cardiovascular risk factors with common carotid artery intima-media thickness in military pilots as representatives of healthy men. Methods. We studied 161 military pilots (age 38 ± 6 years free of cardiovascular disease and diabetes mellitus. Traditional and metabolic risk factors were determined. Plasma CRP was measured by immunonephelometry. The common carotid artery intima-media thickness was measured by ultrasonography in the posterior wall of both common carotid arteries. Results. A total of 66.5% subjects had common carotid artery intima-media thickness > 0.9 mm (p < 0.01. The mean CRP plasma concentration was significantly higher in the subjects with common carotid artery intima- media thickness > 0.9 mm than in those with common carotid artery intima-media thickness ≤ 0.9 mm. In a simple regression analysis age adjusted CRP was associated with common carotid artery intima-media thickness (β = 0.285, p < 0.01, and only high density lipoprotein cholesterol was not associated with common carotid artery intima-media thickness. The association between CRP and common carotid artery intima-media thickness remained highly significant after controlling for body mass index, blood pressure, total cholesterol, low density lipoprotein cholesterol, triglycerides, glycosylated hemoglobin and smoking (p < 0.01. Controlling for glucose, triglycerides to high density lipoprotein cholesterol ratio, and total cholesterol to high density lipoprotein cholesterol ratio resulted in some reduction in the strength of the association, but including waist

  6. ADIPONECTIN AND C-REACTIVE PROTEIN RELATIONSHIP IN PLASMA AND ADIPOSE TISSUE (STUDY AMONG HEALTHY OBESE EGYPTIAN FEMALES)

    International Nuclear Information System (INIS)

    The adipokine, adiponectin inhibits vascular inflammation and acts as an endogenous modulator of obesity - linked diseases. High - sensitive C-reactive protein (hs-CRP) is recently debated as a risk factor and mediator for atherosclerosis. The present study investigated the association between adiponectin and hs-CRP in plasma and adipose tissue, and their relation to body composition and insulin sensitivity in a cohort of normal (30 subjects), obese (30 subjects) and morbidly - obese females (10 subjects). Messenger RNA (mRNA) expression of CRP and adiponectin in human adipose tissue were measured using real-time polymerase chain reaction. Plasma adiponectin and insulin were measured using radioimmunoassay methods, while, plasma hs-CRP was measured using ultrasensitive latex method.Results showed that adiponectin was negatively correlated with weight, BMI and insulin sensitivity index, and positively correlated with HDLc. The plasma hs-CRP levels were negatively correlated with plasma adiponectin. The plasma adiponectin levels being significantly lower and plasma hs-CRP being significantly higher in obese than normal females. Real- Time PCR analysis revealed the expression of CRP m-RNA in human adipose tissue and this was inversely correlated to adiponectin m RNA. These results suggest that elevation of CRP and reduction of adiponectin could emerge as mediators of atherogenesis and insulin resistance

    Background. The clinical diagnosis of pneumonia is sometimes difficult since chest radiographs are often indeterminate. In this study, we aimed to assess whether serum C-reactive protein (CRP) could assist in identifying patients with pneumonia. Methods. For one winter, all consecutive patients with acute respiratory symptoms admitted to the emergency ward of a single center were prospectively enrolled. In addition to chest radiographs, basic laboratory tests, and microbiology, serum levels of CRP were measured at entry. Results. A total of 923 (62.3%) of 1473 patients hospitalized for acute respiratory symptoms were included. Subjects with a final diagnosis of pneumonia had higher serum CRP levels (median 187 mg/L) than those with exacerbations of chronic obstructive pulmonary disease (63 mg/L) or acute bronchitis (54 mg/L, p CRP was accurate in identifying pneumonia (area under the curve 0.84, 95% CI 0.82–0.87). The multilevel likelihood ratio (LR) for intervals of CRP provided useful information on the posttest probability of having pneumonia. CRP intervals above 200 mg/L were associated with LR+ > 5, for which pneumonia is likely, whereas CRP intervals below 75 mg/L were associated with LR CRP may be a useful addition for diagnosing pneumonia in hospitalized patients with acute respiratory symptoms.

  9. C-reactive protein, Rheumatoid factor and circulatory immune complex as markers for monitoring treatment of infective endocarditis

    International Nuclear Information System (INIS)

    Objectives: To evaluate the diagnostic usefulness of serum C-reactive protein (CRP), rheumatoid factor (RF) and circulatory immune complex (CIC) determinations in monitoring the outcome of infective endocarditis (IE). Methodology: In this prospective analytic descriptive study CRP, RF and CIC were measured on admission and 4 weeks after initiation of standard antibiotic regimen in 30 hospitalized patients with IE in an educational hospital between 2006 and 2007 in Ahvaz a city south west Iran . Duke criteria were used for diagnosis of IE. CRP and RF were examined using quantitative neflometry (Binding site kit, UK) and CIC was detected by semi quantitative immune diffusion (Baharafshan SIRD kit, Iran). Data were evaluated using statistical analyses in SPSS (version 12, USA) software for windows. Results: The fall in serum C-reactive protein or RF was significant (P=0.05). Only two of the 30 patients, who had elevated CRP, RF and CIC week four failed to response and one needed cardiac surgery. Conclusions: The C-reactive protein proved to be a good tool for monitoring the treatment of IE. Also RF proved useful in the assessment of patients with IE, but the value of CIC was negligible.

    Full Text Available Background: HsCRP (Highly sensitive C reactive protein is a global indicator for future vascular events in adults detected in blood stream 48 hours before the cardiovascular event. Periodontal disease may increase blood levels of inflammatory markers like IL-6, CRP and HsCRP. Hence the aim of the present study is to evaluate the presence of elevated HsCRP levels in chronic periodontitis patients. Material and Methods: 100 patients who reported for cardiac master health check up were enrolled in the study. The periodontal status was assessed using periodontal probing pocket depth and clinical attachment level. The decayed, missing and filled tooth was recorded using DMFT index. The venous samples of these patients were obtained for recording HsCRP levels. Results: Pearson correlation was used to analyze the relationship between HsCRP level and probing pocket depth, clinical attachment loss and DMFT. The correlation value was 0.051, 0.025 and 0.101 respectively, the correlation is statistically significant for probing pocket depth and clinical attachment level (P>0.05. Chi- square test was performed to study the association between gender and HsCRP, Diabetes Mellitus and HsCRP and Hypertension and HsCRP; the results showed that there is no significant association between any of the above mentioned factors and HsCRP level in blood. Conclusions: We found an increased level of HsCRP in patients with chronic periodontitis which revealed the susceptibility of these patients to cardiac diseases like myocardial infarction and stroke. Hence present day focus in the line of management of cardiac patient has changed from the periodontal perspective.

    Full Text Available Background: Cardiovascular disease is the leading cause of mortality. The previous findings which suggest the reduction in C-reactive protein (CRP levels by statin encouraged us to conduct the present study in which we tested the effects of atorvastatin, on levels of hs-CRP in a prospective randomised clinical trial study on patients with acute coronary syndrome. Materials and Methods: Present prospective randomised clinical trial study conducted on 180 patients who had developed coronary artery disease and presented in emergency departments of Educational-Medical centers of Tabriz University of Medical Sciences. The patients were divided randomly into two groups and then two therapeutic protocols were given to them. One group medicated by high-dose atorvastatin (40 mg and the other group received low-dose atorvastatin (20 mg. All variables were collected by questionnaires and were analyzed. Results: There were 180 patients consisted of 34 females and 56 males in low-dose atorvastatin group (L-DA group, and 30 females and 60 males in high-dose atorvastatin group (H-DA group (P = 0.533. In this study atorvastatin in high doses decreased hs-CRP levels about 40% and in low doses it only caused decrease of 13.3%, and significant correlation was observed between two groups (Paired Sample T-test (P = 0.001. Also atorvastatin in high doses decreased LDL levels about 23% and in low doses it only decreased 10%, and significant correlation was observed between two groups (Paired Sample T-test( (P = 0.001. Atorvastatin in high doses decreased HDL levels about 9% and in low doses it only decreased 6%, and again significant correlation was observed between two groups (P = 0.009. Conclusion: The present study confirms the novel observation that atorvastatin therapy results in a significant reduction in hs-CRP levels.

    As no specific laboratory test has been identified, PFAPA (periodic fever, aphthous stomatitis, pharyngitis and cervical adenitis) remains a diagnosis of exclusion. We searched for a practical use of procalcitonin (PCT) and C-reactive protein (CRP) in distinguishing PFAPA attacks from acute bacterial and viral infections. Levels of PCT and CRP were measured in 38 patients with PFAPA and 81 children diagnosed with an acute bacterial (n=42) or viral (n=39) infection. Statistical analysis with the use of the C4.5 algorithm resulted in the following decision tree: viral infection if CRP≤19.1 mg/L; otherwise for cases with CRP>19.1 mg/L: bacterial infection if PCT>0.65ng/mL, PFAPA if PCT≤0.65 ng/mL. The model was tested using a 10-fold cross validation and in an independent test cohort (n=30), the rule’s overall accuracy was 76.4% and 90% respectively. Although limited by a small sample size, the obtained decision tree might present a potential diagnostic tool for distinguishing PFAPA flares from acute infections when interpreted cautiously and with reference to the clinical context.

    Full Text Available Abstract Background Both low birth weight, an indicator of intrauterine growth restriction, and low grade systemic inflammation depicted by high sensitivity C-reactive protein (hs-CRP have emerged as independent predictors of cardiovascular (CV disease and type 2 diabetes. However, information linking low birth weight and hs-CRP in a biracial (black/white population is scant. We assessed a cohort of 776 black and white subjects (28% black, 43% male aged 24-43 years (mean 36.1 years enrolled in the Bogalusa Heart Study with regard to birth weight and gestational age data were retrieved from Louisiana State Public Health Office. Findings Black subjects had significantly lower birth weight than white subjects (3.145 kg vs 3.441 kg, p Conclusions The deleterious effect of low birth weight on systemic inflammation depicted by the hs-CRP levels in asymptomatic younger adults may potentially link fetal growth retardation, CV disease and diabetes, with important health implications.

  19. Traffic exposure in a population with high prevalence type 2 diabetes - Do medications influence concentrations of C-reactive protein?

    International Nuclear Information System (INIS)

    Type 2 Diabetes (T2D) and particulate air pollution are associated with inflammatory dysregulation. We assessed the modifying effects of diabetes medications on the association of C-reactive protein (CRP), a marker of inflammation, and traffic exposure in adults with T2D (n = 379). CRP concentrations were significantly positively associated with residence ≤100 m of a roadway, >100 m and ≤200 m of a roadway and increased traffic density for individuals using insulin. For individuals using oral hypoglycemic medications (OHAs), CRP was significantly negatively associated with residence >100 m - ≤200 m of a roadway and multiple roadway exposure in an interaction model. Among people with diabetes, individuals on insulin appear to be most vulnerable to the effects of traffic exposure. Disease severity among insulin users may promote the pro-inflammatory response to traffic exposure, though diabetes medications may also modify the response. Possible anti-inflammatory effects of OHAs with traffic exposure merit further evaluation. - Highlights: →We examine traffic exposure in a population with high rates of Type 2 Diabetes. →Differences in CRP were evaluated by traffic levels, medication use and type. →Those on insulin had significantly higher CRP with traffic exposure. →Interaction models demonstrated lower CRP with traffic exposure and OHA use. →Diabetes medications may modify the response to traffic exposure. - Among people with diabetes, individuals on insulin appear to be most vulnerable to the effects of traffic exposure. Diabetes medications may modify the response to traffic.

    2014-06-01

    Full Text Available Background: Frailty may now be regarded as a geriatric syndrome of decreased reserve and resistance to stressors, resulting from cumulative declines across multiple physiologic systems, causing vulnerability to adverse health outcomes including falls, hospitalisation, institutionalisation and mortality. The inflammatory mediators as C-reactive protein have been associated with the development of the geriatric frailty. Several studies have pointed out increased level of homocystiene in frail elderly Increasing frailty was associated with lower bone mineral density, as both bone mass and muscle strength decrease during ageing and this has also been associated with higher risk of osteoporotic fractures in frail elderly. Objective: To compare frail and non-frail elderly regarding Bone mineral density, carotid circulation and serum levels of Homocysteine, coronary risk factors and CRP. Methods: 104 elderly patients, who were assigned to 2 groups. Group A (52 frail participants: diagnosed by Fried’s criteria as applied by Avila-Funes et al., 2008. Group B (52 non-frail participants.All participants were subjected to the following: through history, physical examination, ADL, IADL assessment, MMSE ,GDS, laboratory investigations including; CRP, homocystiene and total lipid profile, measurement of bone mineral density by DEXA and carotid intima-media thickness by carotid duplex. Results: There was no statistically significant difference in age, sex, among both groups.Frail participants had higher ADL and IADL dependence, higher incidence of depression, cognitive impairment and osteoprosis.They also had higher levels of homocystiene , CRP , CIMT and lower levels of HDL cholesterol. Conclusion: Osteoporosis is more prevalent among frail elderly also frailty is associated with more ADL & IADL dependence, higher GDS scores & lower MMSE score in addition to higher mean level of homocystiene, CRP & triglycerides in addition to low serum HDL & higher CIMT

    Background and objective To assess the predictive value of C-reactive protein(CRP) for major adverse cardiac events and the association between CRP level and the coronary lesion morphology and extent in patients with coronary heart disease (CHD).Methods CRP was measured on admission in 177 consecutive elderly (age≥60 years) patients with CHD who underwent coronary angiography. Patients were divided into high CRP group (CRP≥3mg/L) and normal CRP group (CRP <3mg/L). The association between CRP levels and the coronary lesion features, including severity of stenosis (mild, moderate, severe), extent of lesion (diffused or nondiffused), eccentricity of the plaque (eccentric or non-eccentric) were analyzed. Patients were followed up for a mean of 8 months for the occurrences of major adverse cardiac events (MACE). Results Compared with patients in normal CRP group, patients in high CRP group were more frequently to have unstable angina, multi-vessel, diffuse, eccentric lesions, positive remodeling, and non-smooth plaques (P<0.01). Kaplan-Meier analysis showed patients in high CRP group had a significantly lower MACE-free survival rate than patients in normal CRP group (Log-rank = 12.0, P<0.01); Cox regression analysis indicated CRP level as an independent predictor for the occurrence of MACE (OR=3.16, P<0.05) Conclusions High CRP level is associated with more extend, severe and eccentric coronary lesions and is an independent predictor for MACE in elderly patients with CHD.

    Full Text Available Background: It is common in medical practice to see patients having persistent pain and radiculopathy even after undergoing discectomy surgery. Inflammatory cytokines, such as interleukins are produced at the site of disc herniation and are now considered responsible for the pain perceived by the patient. This study has used high sensitive C-reactive protein (HSCRP assay for predicting inflammation around the nerve roots on very same principle, which has used HSCRP for predicting coronary artery diseases in current clinical practice. Thus, purpose of this study is to test whether HSCRP can stand as an objective tool to predict postoperative recovery in patients undergoing lumbar discectomy. That is, to study association between preoperative HSCRP blood level and postoperative recovery with the help of modified Oswestry Back Disability Score. Materials and Methods: A study group consisting of 50 cases of established lumbar disc disease and control group of 50 normal subjects, matched with the study group. Both the study and control groups were subjected to detailed evaluation with the help of modified Oswestry Low Back Pain Scale both pre and postoperatively at 3 months, 6 months and 1-year. The preoperative blood samples were analyzed to assess the HSCRP concentration. All the cases underwent surgery over a period of 1-year by the same surgeon. Results: The level of HSCRP in the study group was between 0.050- and 0.710 mg/dL and in the control group, 0.005-0.020 mg/dL. There was highly significant positive correlation between preoperative HSCRP level and postoperative score at P 10 points, while those with HSCRP level in the range of 0.470 ± 0.163 mg/dL, showed poor recovery (score improved < 10 points. Conclusion: HSCRP will serve as a good supplementary prognostic marker for operative decision making in borderline and troublesome cases of lumbar disc disease.

    Objective: To determine high sensitivity C-reactive protein (hsCRP) levels in patients with acute myocardial infarction (AMI) and its correlation with classical enzyme markers of myocardial damage. Study Design: Observational study. Place and Duration of Study: Department of Emergency Medicine at King Khalid University Hospital, King Saud University, Riyadh and Department of Physiology, from August 2010 to December 2011. Methodology: Consecutive eligible patients with either ST elevation myocardial infarction (STEMI) or non-ST elevation myocardial infarction (NSTEMI) who were admitted to the Emergency Department of King Khalid University Hospital were recruited. A total of 71 subjects were finally selected for the study. The hsCRP, Troponin I (Trop I), creatine kinase myocardial bound (CK-MB), aspartate aminotransferase (AST) and lactate dehydrogenase (LDH) concentrations of all patients with an acute myocardial infarction (AMI) were measured. Results: Among all patients 34 (47.9%) patients had diabetes mellitus, 21 (29.6%) were hypertensive, and 16 (22.5%) had no associated illness. Patients with STEMI had significantly higher levels of CKMB (p=0.0348), LDH (p=0.0471) and hsCRP (p=0.0231) compared to NSTEMI patients. While the differences were non-significant for Trop I (p=0.7022), AST (p=0.9729) and Lp(a) (p=0.5985). Spearman's correlations revealed that CRP correlated significantly with Trop I, CK-MB and LDH. There was a significant predictive relationship of hsCRP with Trop I, LDH and CK-MB while with AST it was nonsignificant. Conclusion: High sensitivity CRP levels is a significant predictor of standard markers for myocardial damage and it may be a useful prognostic marker in acute coronary syndromes. (author)

    Highlights: Black-Right-Pointing-Pointer CRP increases TNF-{alpha} and IL-6 genes expression in matured 3T3-L1 adipocytes. Black-Right-Pointing-Pointer CRP suppresses adiponectin, leptin and PPAR-{gamma} mRNA levels in matured 3T3-L1 cells. Black-Right-Pointing-Pointer Wortmannin reverses effects of CRP on adiponectin, TNF-{alpha} and leptin mRNA levels. Black-Right-Pointing-Pointer CRP may regulate IR, obesity and metabolic syndrome by this mechanism. -- Abstract: Adipose tissue is now recognized to be an important endocrine organ, secreting a variety of adipokines that are involved in the regulation of energy metabolism, insulin resistance and metabolic syndrome. C-reactive protein (CRP) is considered as one of the most sensitive markers of inflammation. A number of studies have shown that elevation of CRP concentrations is an independent predictive parameter of type 2 diabetes mellitus, which is also strongly associated with various components of the metabolic syndrome. The aim of the present study is to investigate the effects of CRP on adipokines genes expression in 3T3-L1 adipocytes. Quantitative real-time PCR analysis revealed that CRP inhibited adiponectin, leptin and peroxisome proliferator-activated receptor-gamma (PPAR-{gamma}) genes expression and raised tumor necrosis factor-{alpha} (TNF-{alpha}) and interleukin-6 (IL-6) mRNA levels in matured 3T3-L1 adipocytes in a dose and time-dependent manner. Pharmacological inhibition of phosphatidylinositol (PI)-3 kinase by wortmannin partially reversed the effects of CRP on adiponectin, TNF-{alpha} and leptin genes expression. These results collectively suggest that CRP regulates adiponectin, TNF-{alpha}, leptin, IL-6 and PPAR-{gamma} genes expression, and that might represent a mechanism by which CRP regulates insulin resistance, obesity and metabolic syndrome.

    Full Text Available Abstract Background Formation of haemorrhagic neovessels in the intima of developing atherosclerotic plaques is thought to significantly contribute to plaque instability resulting in thrombosis. C-reactive protein (CRP is an acute phase reactant whose expression in the vascular wall, in particular, in reactive plaque regions, and circulating levels increase in patients at high risk of cardiovascular events. Although CRP is known to induce a pro-inflammatory phenotype in endothelial cells (EC a direct role on modulation of angiogenesis has not been established. Results Here, we show that CRP is a powerful inducer of angiogenesis in bovine aortic EC (BAEC and human coronary artery EC (HCAEC. CRP, at concentrations corresponding to moderate/high risk (1–5 μg/ml, induced a significant increase in proliferation, migration and tube-like structure formation in vitro and stimulated blood vessel formation in the chick chorioallantoic membrane assay (CAM. CRP treated with detoxi-gel columns retained such effects. Western blotting showed that CRP increased activation of early response kinase-1/2 (ERK1/2, a key protein involved in EC mitogenesis. Furthermore, using TaqMan Low-density Arrays we identified key pro-angiogenic genes induced by CRP among them were vascular endothelial cell growth factor receptor-2 (VEGFR2/KDR, platelet-derived growth factor (PDGF-BB, notch family transcription factors (Notch1 and Notch3, cysteine-rich angiogenic inducer 61 (CYR61/CCN1 and inhibitor of DNA binding/differentiation-1 (ID1. Conclusion This data suggests a role for CRP in direct stimulation of angiogenesis and therefore may be a mediator of neovessel formation in the intima of vulnerable plaques.

    Inflammation and oxidative and dicarbonyl stress play important roles in the pathogenesis of type 2 diabetes. Metformin is the first-line drug of choice for the treatment of type 2 diabetes because it effectively suppresses gluconeogenesis in the liver. However, its "pleiotropic" effects remain controversial. In the current study, we tested the effects of metformin on inflammation, oxidative and dicarbonyl stress in an animal model of inflammation and metabolic syndrome, using spontaneously hypertensive rats that transgenically express human C-reactive protein (SHR-CRP). We treated 8-month-old male transgenic SHR-CRP rats with metformin (5 mg/kg/day) mixed as part of a standard diet for 4 weeks. A corresponding untreated control group of male transgenic SHR-CRP rats were fed a standard diet without metformin. In a similar fashion, we studied a group of nontransgenic SHR treated with metformin and an untreated group of nontransgenic SHR controls. In each group, we studied 6 animals. Parameters of glucose and lipid metabolism and oxidative and dicarbonyl stress were measured using standard methods. Gene expression profiles were determined using Affymetrix GeneChip Arrays. Statistical significance was evaluated by two-way ANOVA. In the SHR-CRP transgenic strain, we found that metformin treatment decreased circulating levels of inflammatory response marker IL-6, TNFα and MCP-1 while levels of human CRP remained unchanged. Metformin significantly reduced oxidative stress (levels of conjugated dienes and TBARS) and dicarbonyl stress (levels of methylglyoxal) in left ventricles, but not in kidneys. No significant effects of metformin on oxidative and dicarbonyl stress were observed in SHR controls. In addition, metformin treatment reduced adipose tissue lipolysis associated with human CRP.

    C-reactive protein (CRP) binds with high affinity to fibronectin (Fn), a major component of the extracellular matrix (ECM), but at physiological pH the binding is inhibited by calcium ions (Ca2+). Because CRP circulates in the blood in Ca2+-bound form, the occurrence of CRP-Fn interactions in vivo has been doubtful. To define the basis of inhibition of CRP-Fn interaction by Ca2+ at pH 7.0, we hypothesized that Fn-binding site on CRP consisted of amino acids co-ordinating Ca2+. Site-directed m...

    The inflammatory hypothesis of schizophrenia (SZ) posits that inflammatory processes and neural-immune interactions are involved in its pathogenesis, and may underpin some of its neurobiological correlates. SZ is the psychiatric disorder causing the most severe burden of illness, not just owing to its psychiatric impairment, but also owing to its significant medical comorbidity. C-reactive protein (CRP) is a commonly used biomarker of systemic inflammation worldwide. There are some conflicting results regarding the behaviour of CRP in SZ. The aims of this study were to verify whether peripheral CRP levels are indeed increased in SZ, whether different classes of antipsychotics divergently modulate CRP levels and whether its levels are correlated with positive and negative symptomatology. With that in mind, we performed a meta-analysis of all cross-sectional studies of serum and plasma CRP levels in SZ compared to healthy subjects. In addition, we evaluated longitudinal studies on CRP levels before and after antipsychotic use. Our meta-analyses of CRP in SZ included a total of 26 cross-sectional or longitudinal studies comprising 85 000 participants. CRP levels were moderately increased in persons with SZ regardless of the use of antipsychotics and did not change between the first episode of psychosis and with progression of SZ (g=0.66, 95% confidence interval (95% CI) 0.43 to 0.88, Pbody mass index. Conversely, higher age correlated with a smaller difference in CRP levels between persons with SZ and controls. Furthermore, CRP levels did not increase after initiation of antipsychotic medication notwithstanding whether these were typical or atypical antipsychotics (g=0.01, 95% CI -0.20 to 0.22, P=0.803, 8 within-group comparisons, n=713). In summary, our study provides further evidence of the inflammatory hypothesis of SZ. Whether there is a causal relationship between higher CRP levels and the development of SZ and aggravation of psychotic symptoms, or whether they

    Alzheimer’s disease (AD) increases dramatically in patients with ischaemic stroke. Monomeric C-reactive protein (mCRP) appears in the ECM of ischaemic tissue after stroke, associating with microvasculature, neurons and AD-plaques, Aβ, also, being able to dissociate native-CRP into inflammatory, mCRP in vivo. Here, mCRP injected into the hippocampal region of mice was retained within the retrosplenial tract of the dorsal 3rd ventrical and surrounding major vessels. Mice developed behavioural/cognitive deficits within 1 month, concomitant with mCRP staining within abnormal looking neurons expressing p-tau and in beta-amyloid 1-42-plaque positive regions. mCRP co-localised with CD105 in microvessels suggesting angiogenesis. Phospho-arrays/Western blotting identified signalling activation in endothelial cells and neurons through p-IRS-1, p-Tau and p-ERK1/2-which was blocked following pre-incubation with mCRP-antibody. mCRP increased vascular monolayer permeability and gap junctions, increased NCAM expression and produced haemorrhagic angiogenesis in mouse matrigel implants. mCRP induced tau244–372 aggregation and assembly in vitro. IHC study of human AD/stroke patients revealed co-localization of mCRP with Aβ plaques, tau-like fibrils and IRS-1/P-Tau positive neurons and high mCRP-levels spreading from infarcted core regions matched reduced expression of Aβ/Tau. mCRP may be responsible for promoting dementia after ischaemia and mCRP clearance could inform therapeutic avenues to reduce the risk of future dementia.

  6. Prognostic value of C-reactive protein and neutrophil-to-lymphocyte ratio in patients with hepatocellular carcinoma

    International Nuclear Information System (INIS)

    Accumulating evidence indicates that components of the systemic inflammatory response, such as C-reactive protein (CRP) and neutrophil-to-lymphocyte ratio (NLR), have been associated with prognosis of various cancers. We aimed to elucidate whether CRP and NLR could serve as potential surrogate markers for response and survival in patients with hepatocellular carcinoma (HCC). The study population consisted of 318 consecutive patients with HCC. CRP and NLR were measured at baseline with follow-up measurements. With the mean follow-up of 13.9 months, the median survival time was 13.8 months. Child-Pugh class, tumor size > 5 cm, tumor multiplicity, presence of portal vein thrombosis, α-fetoprotein > 200 ng/mL, CRP > 6.3 mg/L and NLR > 2.3 were identified as independent factors for worse survival of HCC (all p < 0.05). Patients with elevated CRP (> 6.3 mg/L) and elevated NLR (> 2.3) had a significantly shorter overall survival than those with low CRP and low NLR (all p < 0.001). The combined use of CRP and NLR provided incremental prognostic information. With significant inter-correlations, levels of CRP and NLR escalated with aggravating Child-Pugh class from A to C or progressing tumor stage from I to IV. CRP and NLR on baseline and serial measurements were well predictive of treatment response (p < 0.001). CRP and NLR are independent indicators for survival in HCC patients, reflecting tumor burden and hepatic reserve. Their role in predicting tumor response and survival is more enhanced when used in combination. This study suggests that CRP and NLR are important prognostic biomarkers for HCC

    Full Text Available Background/Aim. C-reactive protein (CRP is considered to be an indicator of postoperative complications in abdominal surgery. The aim of this study was to determine the significance of serial measurement of CRP in drainage fluid in the detection of anastomotic leakage (AL in patients with colorectal resection. Methods. CRP values in serum and drainage fluid, respectively, were measured on the first, third, fifth, and seventh postoperative day (POD in 150 patients with colorectal resection and primary anastomosis. The values obtained were compared between the group of patient without complications of surgical treatment and those with AL. Results. Clinically evident AL was observed in 15 patients - in two (4.2% patients with left colonic surgery, and 13 (12.6% patients with colorectal anastomosis. Mean values of CRP were higher in the patients with AL than in the patients without complications, both in serum and drainage fluid, with the most significant differences recorded on the PODs 5 and 7 (p < 0.001. Correlation analysis showed a positive correlation between serum and drainage fluid CRP levels in both groups of patients. Serum and drainage fluid CRP values on the PODs 5 and 7 are most important in the detection of AL. In 80% of patients with CRP values in the drainage fluid of 53 mg/L for the POD 5 and 42 mg/L for the POD 7 AL was observed. The method specificity was 77% for the POD 5, and 83% for the POD 7. All the patients with CRP values in drainage fluid above 108 mg/L on the POD 5 and 93 mg/L on the POD 7 had AL. Conclusion. Serial measurement of CRP in drainage fluid can reliably be used in the detection of AL in patients with colorectal resection. The most significant values obtained on the PODs 5 and 7 were positively correlated with the values registered in serum.

    We conducted a meta-analysis of 13 randomized trials comparing the efficacy of rosuvastatin versus atorvastatin in reducing concentrations of C-reactive protein (CRP). We searched PubMed, Ovid, and Elsevier databases until June 2014. Search terms included C-reactive protein or CRP, rosuvastatin, atorvastatin, randomized, randomly, and randomization; 13 trials (3798 patients) were included. Funnel plots for CRP were inspected to assess publication bias. The pooled analysis demonstrated the benefit of rosuvastatin over atorvastatin therapy for all 13 trials (mean difference [MD] = -0.11, which is standardized mean with no unit although the raw data before pooling is mg/L, 95% confidence interval -0.15 to -0.07, P < .0001) with no evidence of significant publication bias (I(2) = 6.9%, P = .377). Subgroup analysis indicated a significant benefit of rosuvastatin over atorvastatin regarding the 1/1 dose ratio (MD = -0.14, 95% CI -0.21 to -0.06) and 1/2 dose ratio (MD= -0.11, 95% CI -0.16 to -0.05). Cumulative and influence analyses showed accuracy and stability for the estimation mentioned earlier. Our meta-analysis shows that rosuvastatin produces better reduction in CRP concentrations than atorvastatin at a dose ratio of 1/1 and 1/2 (rosuvastatin/atorvastatin), respectively. PMID:26271127

  10. Immunoassay of C-reactive protein by hot electron induced electrochemiluminescence using integrated electrodes with hydrophobic sample confinement

    International Nuclear Information System (INIS)

    Highlights: · C-reactive protein has been determined in the concentration range 0.01-10 mg L-1 using an electrochemiluminescence microchip which employs integrated electrodes with hydrophobic sample confinement. · This arrangement enables very simple and fast CRP analysis amenable to point-of-care applications. - Abstract: C-reactive protein (CRP) was determined in the concentration range 0.01-10 mg L-1 using hot electron induced electrochemiluminescence (HECL) with devices combining both working and counter electrodes and sample confinement on a single chip. The sample area on the electrodes was defined by a hydrophobic ring, which enabled dispensing the reagents and the analyte directly on the electrode. Immunoassay of CRP by HECL using integrated electrodes is a good candidate for a high-sensitivity point-of-care CRP-test, because the concentration range is suitable, miniaturisation of the measurement system has been demonstrated and the assay method with integrated electrodes is easy to use. High-sensitivity CRP tests can be used to monitor the current state of cardiovascular disease and also to predict future cardiovascular problems in apparently healthy people.

    Full Text Available Despite substantial differences in ethnicities, habits, cultures, the prevalence of traditional cardiovascular risk factors and affordable therapies, atherosclerosis remains the major cause of death in developing and developed countries. However, irrespective of these differences, inflammation is currently recognized as the common pathway for the major complications of atherosclerosis, stroke, and ischemic heart disease. A PubMed search was conducted for “high-sensitivity C-reactive protein” (hs-CRP in combination with the terms race, ethnicity, gender, prevalence, geographic, epidemiology, cardiovascular, obesity, diabetes, hypertension, cholesterol, smoking, ischemic heart disease, stroke, and mortality. This review includes the articles that pertained to the topic and additional articles identified from the reference lists of relevant publications. This review describes the marked differences in cardiovascular mortality across countries and ethnicities, which may be attributed to inequalities in the prevalence of the classic risk factors and the stage of cardiovascular epidemiological transition. However, hs-CRP appears to contribute to the prognostic information regarding cardiovascular risk and mortality even after multiple adjustments. Considering the perception of cardiovascular disease as an inflammatory disease, the more widespread use of hs-CRP appears to represent a valid tool to identify people at risk, independent of their ancestry or geographic region. In conclusion, this review reports that the complications associated with vulnerable atherosclerotic plaques are triggered by the major mechanisms of dyslipidemia and inflammation; whereas both mechanisms are influenced by classic risk factors, hs-CRP contributes additional information regarding cardiovascular events and mortality.

    Full Text Available Meningitis is one of the commonest and most feared neurological diseases in children and adults with high morbidity and mortality. Analysis of cerebrospinal fluid (CSF in meningitis by routine tests does not always provide rapid definite information as far as causative agent is concerned and there is need for additional tests on CSF. Estimation of CSF C-reactive protein (CRP and comparing it with the levels of serum CRP levels can overcome this difficulty. In view of this background, the present study was undertaken to evaluate the sensitivity of CRP in CSF and its relation to the serum values. 32 cases of pyogenic meningitis between 18 to 65 years and 28 individuals undergoing lumbar puncture for various surgical procedures were taken as controls from Neurology department of Government General Hospital, Vijayawada. Lumbar puncture was done in all cases and CSF was collected in sterile bottles and blood was drawn within 1 hour of lumbar puncture. Analysis of the samples was done in the Departments of Biochemistry, Microbiology and Pathology of Siddharta Medical College, Vijayawada. CRP was estimated using Latex Slide Agglutination semi quantitative method (Accurex. ANOVA, Chi-Square test and Z test were used for statistical analysis. The sensitivity, specificity, positive predictive value (PPV and negative predictive value (NPV was defined for each test. Receiver operating characteristic (ROC curves were plotted. CSF protein was significantly high and CSF/serum ratio was altered. In majority of cases CSF sugar was less than 2/3 of blood sugar and absent in many of them. CRP was positive in almost all cases and was in the range of 0.6 to 9.6 mg/dl and values were corresponding in the serum. CSF CRP is a novel marker with high sensitivity and specificity. CRP can be used as a supportive evidence of meningitis, as these tests are cost-effective and it can be used on regular basis along with other routine tests to diagnose pyogenic meningitis in

We evaluated serum high-sensitivity C-reactive protein (hs-CRP and lipoprotein-related phospholipase A2 (Lp-PLA2 in patients who had acute ischemic stroke.Methods: In 200 patients who presented to an emergency service (acute ischemic stroke, 102 patients; control with no stroke, 98 patients, stroke patients were evaluated with the Canadian neurological scale and diffusion-weighted magnetic resonance imaging, and all patients were evaluated with the Glasgow coma scale and their serum hs-CRP level and Lp-PLA2 activity were assessed. The volume of stroke lesions was calculated from magnetic resonance images.Results: Patients who had stroke had higher mean serum hs-CRP level (stroke, 7±6 mg/dL; ­control, mean ± standard deviation 1±1 mg/dL; P≤0.001 and Lp-PLA2 activity (stroke, mean ± standard deviation 113±86 nmol/min/mL; control, mean ± standard deviation 103±50 nmol/min/mL; P≤0.001 than control patients who did not have stroke. The mean hs-CRP level and Lp-PLA2 activity were higher in patients who had greater stroke severity (lower Canadian neurological scale score and were higher in patients who had larger volume strokes. Conclusion: Higher hs-CRP level and Lp-PLA2 activity are significantly associated with more severe neurologic impairment and larger infarct size in patients who have acute ischemic stroke. These biomarkers may be useful for rapid diagnosis and prediction of ischemic tissue volume in the early stage of ischemic stroke. These findings may be important for health

    Full Text Available Objectives: Despite the fact that many studies have shown that the role of high sensitivity C-reactive protein (Hs-CRP in inflammation diseases, the role of this molecule in severe head injury (SHI has not been understood clearly. Severe head injury was defined as a trauma to the head frequently found in Emergency Units where some cases result in mortality. Severe head injury was defined as GlasgowComa Scale (GCS score between 3 and 8. Based on this data, we felt that it was important to determine the role of Hs-CRP as a predictor of SIRS in SHI patients.Method: This was a Cohort prospective study about the role of serum Hs-CRP as a predictor for Systemic inflammatory response syndrome (SIRS in SHI patients at Sanglah General Hospital, Bali-Indonesia from August 2012 to February 2013. A number of 60 patients fulfilled the inclusive criteria. The data were analyzed descriptively to show the characteristics of the samples and was analyzed using univariate andmultivariate analysis to determine the predictor factors for SIRS in SHI patients. A confidence interval of 95% (p < 0.05 was applied.Results: From 60 samples collected, there were 43 males (71.7% and 17 females (28.3%, the majority age of the samples were 20-40 years old (21 samples, 35%. On the first day 49 samples (81.6% had elevated serum Hs-CRP levels. Fifty seven samples (95% had SIRS, and only 3 samples (5% did not have SIRS. Bivariate analysis between Hs-CRP level and SIRS was significant (p = 0.001. Multivariate analysis showed that pneumonia and highHs-CRP serum levels were significant predictor factors for SIRS in SHI patients.Conclusion: High serum Hs-CRP levels could be used as a reliable predictor factor for SIRS in SHI patients.

    Hypersensitive C-reaction protein (hsCRP) may be a risk factor for cognitive impairment resulting from Alzheimer's disease (AD), stroke, and vascular dementia. This study explored the correlation of peripheral blood hsCRP level with cognitive decline due to high altitude exposure. The study was conducted on 100 male military participants who had never been to high altitude. Cerebral oxygen saturation monitoring, event related potentials (P300, N200) detection, and neurocognitive assessment was performed and total hsCRP, interleukin-6 (IL-6), and homocysteine was estimated at 500 m altitude, 3650 m altitude, 3 day, 1, and 3 month post arriving at the base camp (4400 m), and 1 month after coming back to the 500 m altitude. High altitude increased brain oxygen saturation, prolonged P300 and N200 latencies, injured cognitive functions, and raised plasma hsCRP levels. But they all recovered in varying degrees at 1 and 3 month post arriving at the base camp (4400 m). P300 latencies and hsCRP levels were strongly correlated to cognitive performances. These results suggested that cognitive deterioration occurred during the acute period of exposure to high altitude and may recover probably owning to acclimatization after extended stay at high altitude. Plasma hsCRP is inversely correlated to neurological cognition and it may be a potential biomarker for the prediction of high altitude induced cognitive dysfunction. PMID:26731740

    目的:探讨儿童热性惊厥患儿 C-反应蛋白(CRP)与外周血白细胞计数(WBC)水平的变化。方法选择热性惊厥与同期住院期间发热无惊厥的患儿,检测其 WBC 与 C-反应蛋白水平并进行统计学分析。结果惊厥组中30例 CRP 水平升高,WBC 值为(13.6±4.5)×109/ L;78例 CRP 值正常,WBC 值为(12.2±4.6)×109/ L。非惊厥组中52例 CRP 值增高,WBC 值为(9.8±4.3)×109/ L;46例 CRP 值正常,WBC 值为(7.6±3.2)×109/ L。无论 CRP 是否增高,惊厥组的 WBC 值明显高于非惊厥组,差异有统计学意义(P <0.05)。惊厥组78例 CRP 水平正常者中 WBC 值增高52例,占66.7%;而非惊厥组46例 CRP 水平正常者中 WBC 值增高10例,仅占21.7%,差异有统计学意义(P <0.05)。结论在同样因素影响下,热性惊厥患儿外周血 WBC 值与 CRP 水平或许不平行,且 WBC值常高于非惊厥患儿。%Objective To study the changes of C-reactive protein(CRP)and peripheral white blood cell(WBC)levels in children with febrile convulsions. Methods Children with fever were divid-ed into two groups(108 children with febrile convulsions and 98 children without febrile convulsions). The levels of CRP and WBC were detected and statistically analyzed. Results The CRP levels were ele-vated in 30 children with febrile convulsions,whose WBC counts were(13. 6 ± 4. 5)× 109 / L;The CRP levels were normal in 78 children with febrile convulsions,whose WBC counts were(12. 2 ± 4. 6)× 109 / L. The CRP levels were elevated in 52 children without febrile convulsions,whose WBC counts were (9. 8 ± 4. 3)× 109 / L;The CRP levels were normal in 46 children without febrile convulsions,whose WBC counts were(7. 6 ± 3. 2)× 109 / L. Whether the levels of CRP increased or not,the WBC counts in children with febrile convulsions were obviously higher than those in children without febrile convulsions, there were significant differences(P < 0. 05
