    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.

    Hereditary angioedema (HAE) patients experience recurrent episodes of angioedema attacks that can be painful, disfiguring and even life-threatening. The disorder results from a mutation in the gene that controls the synthesis of C1-inhibitor (C1INH). C1INH is a major regulator of activation of the contact system. It is often assumed that attacks results from uncontrolled local activation of the contact system with subsequent formation of bradykinin. To evaluate the involvement of inflammatory reactions in HAE, we analysed C-reactive protein (CRP) levels. HAE patients included in a clinical database of recombinant human C1-inhibitor (rhC1INH) studies were evaluated. For the current study we analysed CRP levels when patients were asymptomatic, during a clinical attack and in a follow-up period, and correlated these with the clinical manifestations of the attack. Data from 68 HAE patients were analysed and included CRP levels on 273 occasions. While asymptomatic, 20% of the patients analysed had increased CRP. At the onset of the attack (P = 0·049) and during the next 24 h CRP rose significantly (P = 0·002) in patients with an abdominal location, and post-attack levels were significantly higher in these patients than in patients with attacks at other locations (P = 0·034). In conclusion, CRP levels are elevated in a substantial proportion of asymptomatic HAE patients. Levels of CRP increase significantly during an abdominal attack. These data suggest low-grade systemic inflammatory reactions in HAE patients as well as a triggering event for attacks that starts prior to symptom onset.

    Full Text Available 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 (≥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.

    M R Namazi

    2015-01-01

    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.

    @@ Arole for inflammation has become well established over the past decade or more in theories describing the atherosclerotic disease process.1,2 From a pathological viewpoint, all stages, ie, initiation, growth, and complication of the atherosclerotic plaque,3,4 might be considered to be an inflammatory response to injury. 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

Methods:This prospective case control study was conducted in the gynecology clinic of the current hospital. A total of 64 women (33 with a history of recurrent and/or treatment resistant vaginitis as study group and 31 healthy women as control group were enrolled in the study. The recorded parameters were; age, presenting symptom, educational level, socioeconomic status, fre quency of vaginal douching (VD, peripheral blood leukocyte count, CRP levels in VWF, vaginal culture, fresh vaginal smear and urinalysis. Results: The study group had statistically significantly lower educational level and socioeconomic status than the control group (p<0.05. The mean levels of peripheral blood leukocyte count and leukocyte count on the fresh vaginal smear, leukocyturia and VWF CRP levels were statistically significantly higher in the study group (p<0.05. In patients who had ≥ 3 times a week VD had also statistically significantly higher VWF CRP levels (p=0.012. Conclusion:According to this study, recurrent and/or treatment resistant vaginitis is more common in women who have lower socioeconomic status/educational level and who perform more frequently VD, and VWF CRP levels may be a good marker for the diagnosis of disease.

    Elevated markers of systemic inflammation are associated with the development of acute coronary syndromes, but there is no current explanation for increased inflammation in overtly healthy individuals. The influence of genetic control of the inflammatory response on the observed variability is unknown. We studied the frequency of four polymorphisms in interleukin (IL) 1 genes, known to modulate inflammation, in 454 individuals undergoing coronary angiography and analysed their influence on plasma C-reactive protein (CRP) and fibrinogen levels. Females and smokers had higher levels of CRP than males (Pi = 0.001) and non-smokers (Pi = 0.001). Patients with genotype 2.2 for the IL-1B(+3954) polymorphism had twice the median CRP levels of patients who were genotype 1.1 (4.33 vs 2.01 mg/l; P = 0.001). Patients with genotype 1.2 or 2.2 at the IL-1A(+4845) polymorphism also had higher median CRP (2.92 vs 2.05 mg/l, Pi = 0.023). In multivariate analyses, CRP levels remained significantly associated with IL-1 polymorphisms after adjustment for smoking, gender and age. Fibrinogen levels had similar associations with the IL-1 genotypes. These data indicate that IL-1 gene polymorphisms known to affect the inflammatory response are highly related to plasma levels of CRP and fibrinogen in patients referred for coronary angiography.

    Full Text Available Dengue has broad clinical presentation with unpredictable clinical evolution and outcome. We aimed to evaluate the utility of C-reactive protein (CRP levels for distinguishing between mild and severe cases in the early phase of the dengue illness. We retrospectively evaluated adults with dengue from 2006 to 2014, according to 1997 and 2009 World Health Organization (WHO criteria for severity. Of 191 included patients, 32.9% had nonshock dengue hemorrhagic fever (DHF, 3.1% dengue shock syndrome (DSS, and 7.9% severe dengue. The risk of DHF/DSS and severe dengue is significantly related to the increasing levels of CRP. Of 191 patients, 97 had CRP levels measured during the febrile (days 1–3; 85 during the critical (days 4–6; and 9 during the convalescent (days 7–10 illness phases. During the febrile phase, there was significant higher CRP level for DSS versus DF/nonshock DHF and severe dengue versus nonsevere dengue, with CRP cutoff level 30.1 mg/L (area under the receiver operating characteristic curve (AUC, 0.938; 100% sensitivity, 76.3% specificity and 24.2 mg/L (AUC, 0.717; 70% sensitivity, 71.3% specificity, respectively. Our study highlights the utility of the CRP levels in early prediction of DSS and severe dengue in adult patients.

    Full Text Available Background: Smoking plays a key role in increasing the inflammatory marker C-reactive protein (CRP. Aims: To examine inverse correlation between CRP and magnesium levels in smokers and nonsmokers. Materials and Methods: A total of 192 healthy adult male subjects were included in the present study, out of which 96 were smokers and the remaining 96 were nonsmokers having age range from 20 to 40 years, and all the subjects belonged to District Matyari of Hyderabad. Serum CRP was measured by NycoCard standard kit method and magnesium levels by DiaSys standard kit method in smokers and nonsmokers. Results: The levels of serum CRP in smokers (14.62 ± 0.16 mg/L is high as compared to nonsmokers (4.81 ± 0.38 mg/L, which is highly significant (P < 0.001. However, inverse results were seen for serum magnesium levels which were significantly higher (P < 0.001 in nonsmokers (2.52 ± 0.18 mg/L as compared to the smokers (1.09 ± 0.38 mg/dL. A significant (P < 0.001 inverse relationship between serum CRP and magnesium concentrations were seen in smokers. Conclusion: This result shows that smoking increases serum CRP, an inflammatory marker parallel to decrease in serum magnesium levels in smokers having 20-40 years of age.

    2012-02-01

    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.

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.

    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.

  10. 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.

    Full Text Available Individuals from low socioeconomic backgrounds are disproportionately affected by the burden of cardiovascular disease (CVD, yet data regarding risk factors in this population are lacking, particularly regarding emerging biomarkers of CVD such as C-reactive protein (CRP. We measured high-sensitivity CRP and examined its association with demographic and lifestyle factors in a sample of 792 participants aged 40–79 years from the Southern Community Cohort Study, which has an over-representation of socioeconomically disadvantaged individuals (over 60% with a total annual household income 3 mg/L varied significantly by sex, race, smoking status, and body mass index (BMI. The multivariable-adjusted prevalence odds ratios (ORs (95% CIs for having elevated CRP were 1.6 (1.1–2.3 for women vs. men, 1.4 (0.9–2.0 for African Americans vs. whites, 2.3 (1.4–3.8 for African American women vs. white men, 1.8 (1.2–2.7 for current smokers vs. non-smokers, and 4.2 (2.7–6.6 for obese (BMI 30.0–44.9 kg/m2 vs. healthy-weight (BMI 18.3–24.9 kg/m2 participants. Further stratified analyses revealed that the association between BMI and elevated CRP was stronger among African Americans than whites and women than men, with prevalence ORs (95% CI comparing obese vs. healthy-weight categories reaching 22.8 (7.1–73.8 for African American women. In conclusion, in this socioeconomically disadvantaged population, sex, race, smoking, and BMI were associated with elevated CRP. Moreover, inflammatory response to obesity differed by race and sex, which may contribute to CVD disparities.

    Anitha, G.; Nagaraj, M.; Jayashree, A.

    2013-01-01

    Background: Numerous cross-sectional studies have suggested that chronic periodontitis is a risk factor for cardiovascular diseases. There is evidence that periodontitis and cardiovascular diseases are linked by inflammatory factors including C-reactive protein. The purpose of the study was to investigate the levels of CRP and PNM cells as a marker of inflammatory host response in the serum of chronic periodontitis patients and in patients with CVD. Materials and Methods: Study population included 75 patients; both male and female above 35 years were included for the study. The patients were divided into three groups of 25 each – Group I: Chronic periodontitis patients with CVD, Group II: Chronic periodontitis patients without CVD and Group III: Control subjects (without chronic periodontitis and CVD). Patients with chronic periodontitis had ≥8 teeth involved with probing depth (PD) ≥5 mm involved. The control group had PD ≤ 3 mm and no CVD. Venous blood was collected from the patients and C-reactive protein levels were analyzed by immunoturbidimetry. PMN was recorded by differential count method. Results: On comparison, OHI-S Index, GI, mean PD, CRP and PMN values showed significant difference from Group I to III. CRP level was highly significant in Group I when compared with Group II and Group III. PMN level was highly significant in Group I when compared with Group III PMN level which was not significant. Conclusion: This study indicated that periodontitis may add the inflammation burden of the individual and may result in increased levels of CVD based on serum CRP levels. Thus, controlled prospective trials with large sample size should be carried out to know the true nature of the relationship if indeed one exists. PMID:24049333

    BACKGROUND AND PURPOSE: The C-C chemokine receptor 5-Δ32 deletion (CCR5-Δ32) has been associated with lower levels of C-reactive protein (CRP), but the effect on cardiovascular diseases is uncertain. This study addresses the impact of CCR5-Δ32 on the risk of low-grade inflammation...... and hospitalization with cardiovascular diseases in a large cohort of blood donors. METHODS: Genotyping of 15,206 healthy participants from The Danish Blood Donor Study for CCR5-Δ32 was performed and combined with CRP measurements and questionnaire data. Cardiovascular disease diagnoses were identified by ICD-10...... codes in the Danish National Patient Registry. RESULTS: CCR5-Δ32-carriers had a higher risk of hospitalization for cardiovascular diseases when compared with wild-type homozygotes (hazard ratio = 1.35, 95%-confidence interval: 1.00-1.87). CRP levels were unaffected by the CCR5-Δ32 deletion. CONCLUSION...

    Full Text Available The socio-demographic, behavioral and anthropometric correlates of C-reactive protein levels were examined in a representative young adult Brazilian population. The 1982 Pelotas Birth Cohort Study (Brazil recruited over 99% of births in the city of Pelotas that year (N = 5914. Individuals belonging to the cohort have been prospectively followed up. In 2004-2005, 77.4% of the cohort was traced, members were interviewed and 3827 individuals donated blood. Analyses of the outcome were based on a conceptual model that differentiated confounders from potential mediators. The following independent variables were studied in relation to levels of C-reactive protein in sex-stratified analyses: skin color, age, family income, education, parity, body mass index, waist circumference, smoking, fat/fiber/alcohol intake, physical activity, and minor psychiatric disorder. Geometric mean (95% confidence interval C-reactive protein levels for the 1919 males and 1908 females were 0.89 (0.84-0.94 and 1.96 mg/L (1.85-2.09, respectively. Pregnant women and those using oral contraceptive therapies presented the highest C-reactive protein levels and all sub-groups of women had higher levels than men (P < 0.001. Significant associations between C-reactive protein levels were observed with age, socioeconomic indicators, obesity status, smoking, fat and alcohol intake, and minor psychiatric disorder. Associations were stronger at higher levels of C-reactive protein and some associations were sex-specific. We conclude that both distal (socio-demographic and proximal (anthropometric and behavioral factors exert strong effects on C-reactive protein levels and that the former are mediated to some degree by the latter.

    Full Text Available Background Clinical studies have shown that precipitation of urate crystals in joints of hyperuricemic patients could lead to systemic inflammation; however, this subject has been little explored in patients undergoing hemodialysis. Objectives We carried out this study in order to evaluate the association of serum uric acid (SUA levels with plasma concentrations of CRP, an inflammatory marker, and ferritin in hemodialysis patients. Materials and Methods This cross-sectional study was conducted on 182 hemodialysis patients in two hemodialysis wards in Iran. Required laboratory parameters, including serum levels of uric acid, C-reactive protein, lipid profiles (cholesterol, triglyceride, HDL, LDL, and ferritin were measured. Demographic data were also collected with the self-report survey. P Value less than 0.05 is considered significant. Results Higher serum levels of uric acid and CRP were seen in 44% and 47% of the patients, respectively. Hyperferritinemia was observed in 80% of participants. Although there was a significant relationship between SUA level and plasma triglyceride (P = 0.007, a linear correlation indicated that SUA level had no significant association with CRP and ferritin. Conclusions Our results indicated that there is no statistical relationship between SUA level and CRP and serum ferritin. Detailed investigations with larger sample size are recommended.

    Conclusions: Treatment with 3 months metformin monotherapy for newly diagnosed Type-2 DM has shown a significant decrease in high-sensitivity-CRP level in Type 2 diabetes. This positive effect may be because of the decreased in the expression of proinflammatory cytokines and other mediators, including adhesion molecules, suggests that these processes may contribute to atherogenesis because atherosclerosis is also an inflammatory condition. However, this effect is probably dependent on improving glycemic control. [Int J Basic Clin Pharmacol 2015; 4(1.000: 46-50

    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

    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. PMID:22152006

  10. 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)

    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.

    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

    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

    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.

    The role of high sensitivity C-reactive protein (hsCRP) in predicting prognosis after stroke in the Asian population has not been investigated. We hypothesized that elevated levels of hsCRP were associated with worsening prognosis after stroke in Chinese patients. Two hundred and ninety consecutive patients with first-onset stroke and 290 age- and gender-matched control subjects without any cerebrovascular disease were enrolled for study. Plasma hsCRP level was detected and subsequent vascular events and death were recorded in both groups over a 5-year period. Compared to control group, patients presenting with stroke had higher plasma hsCRP level (3.3±3.8 vs 1.3±2.2 mg/L, P < 0.01). Furthermore, in the group of patients with stroke, the mean plasma hsCRP level was higher in patients who developed subsequent vascular diseases or died as compared with the patients without further complications (4.4±4.3 vs 2.7±3.3 mg/L, P< 0.01). Compared to the lowest tertile of hsCRP level, the relative risk for vascular events or death in stroke patients was 2.91 in the highest tertile ofhsCRP (95% CI, 1.54-5.50, P = 0.001). This increase in relative risk for vascular events or death in stroke patients continued after adjustment for age, sex and other cardiovascular risk factors such as hypertension and diabetes (OR: 2.771, 95% CI: 1.367-5.617, P = 0.005). These findings indicate that increased hsCRP level is associated with worsening prognosis after stroke in Chinese patients and suggests that inflammation is correlated with stroke outcome.

    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.

    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.

  19. 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)

    Full Text Available Abstract Background Brachycephalic dogs have unique upper respiratory anatomy with abnormal breathing patterns similar to those in humans with obstructive sleep apnea syndrome (OSAS. The objective of this study was to evaluate the correlation between anatomical components, clinical signs and several biomarkers, used to determine systemic inflammation and myocardial damage (C-reactive protein, CRP; Haptoglobin, Hp; cardiac troponin I, cTnI, in dogs with brachycephalic upper airway obstructive syndrome (BAOS. 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 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 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 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.

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

    Full Text Available Petr Schalek, Zuzana Hornáčková, Aleš Hahn Ear, Nose and Throat department, 3rd Medical Faculty of Charles University, Prague, Czech Republic Background: Acute rhinosinusitis (ARS has been shown to significantly reduce patient quality of life (QoL. While the QoL in patients with chronic rhinosinusitis has been the subject of intensive research over the last decade, studies measuring the impact of ARS on patient QoL have remained relatively scarce. The aim of this study was to determine the relationship between the QoL and parameters suggestive of acute bacterial rhinosinusitis (C-reactive protein [CRP] levels and positive culture and to see if measurement of the QoL could be used as an indicator for antibiotic treatment in ARS.Methods: Eighty patients with ARS were enrolled in the study. A novel QoL instrument for patients with ARS, called Measurement of Acute Rhinosinusitis (MARS questionnaire, was given to patients at the time of diagnosis. We assessed patient QoL, obtained endoscopically guided cultures from the middle meatus, and measured levels of CRP. The relationship between QoL MARS scores (QoL-Mscores and CRP was determined using a correlation coefficient. To compare QoL-Mscores, relative to culture-positive and culture-negative patients, the Student’s t-test was used.Results: No correlation between the QoL, assessed using the MARS questionnaire, and positive middle meatus culture was demonstrated (P=0.332. A weak correlation was found between QoL-Mscores and CRP values, with a correlation coefficient of 0.221 and P=0.0498.Conclusion: No correlation between the QoL in ARS patients and positive culture was found in this study. The clinical significance of the correlation between QoL-Mscores and CRP values in the antibiotic decision making process needs further research.

    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

    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.

    Elevated C-reactive protein (CRP) levels have been found in patients with several malignancies. The aim of the present study was to analyze the diagnostic and prognostic values of CRP levels measurement in esophageal cancer (EC) patients in relation to its different histological subtypes (squamous cell carcinoma-ESCC and adenocarcinoma-AC of esophagus) and compared them with classic tumor markers-carcinoembryonic antigen (CEA) and squamous cell cancer antigen (SCC-Ag). The diagnostic sensitivity, specificity, and the areas under receiver operating characteristic curves (AUC) for all the proteins tested were defined. Serum CRP levels were statistically higher in EC, ESCC, and AC patients compared to healthy subjects and significantly increased in EC and ESCC patients with the presence of lymph node and distant metastases. The percentage of elevated CRP results in all the analyzed subgroups (EC, ESCC, and AC) was higher than CEA and SCC-Ag, similarly as AUC for CRP in comparison to SCC-Ag. Serum CRP level was a significant predictor of EC and ESCC patients' survival in univariate analysis. In conclusion, these results indicate that CRP can be used as an adjunct in evaluating the tumor markers-CEA and SCC-Ag and may improve the clinical diagnosis and follow-up of EC patients, especially for ESCC subgroup.

    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.

    Full Text Available Although the alterations of lipid profile in lung cancer have been documented, the prognostic value of serum HDL-C level and its correlation with inflammation in NSCLC remain unknown.Levels of preoperative serum lipid concentrations (including HDL-C, LDL-C, TC, and TG and the inflammatory biomarker C-reactive protein level (CRP were retrospectively analyzed in 228 patients with NSCLC and in 300 healthy controls. The serum lipid levels in these two populations were compared. Univariate and multivariate cox hazards analyses were performed to investigate the prognostic value of serum lipid levels in NSCLC. The correlation between CRP and lipid profile were also analyzed.Compared with those in normal controls, the serum HDL-C, LDL-C, and TC levels were statistically decreased and the TG levels were significantly increased in 228 NSCLC patients. The patients with decreased levels of HDL-C had significantly lower 5-year survival rates than those with normal HDL-C, not only in the whole NSCLC cohort but also in the subgroups stratified according to the disease T, N classifications, and metastasis, whereas the other lipid components were not independent prognostic factors for NSCLC. Of the lipid components, a lower HDL-C level was observed more often in patients with a high CRP level than in those with a normal CRP level. Spearman's rank correlation analysis revealed that the HDL-C level presented a negative correlation with the CRP level (r = -0.360, p<0.001.A decreased level of preoperative HDL-C was found to be associated with poor survival in patients with NSCLC. Serum HDL-C level may be a clinical prognosis factor for NSCLC patients. In addition, a negative correlation was present between the levels of HDL-C and CRP, the well-known inflammation biomarker.

Exposure to John Cunningham virus (JCV is a prerequisite for PML (progressive multifocal leukoencephalopathy. To assess JCV exposure in multiple sclerosis patients, we performed a serological examination, obtained the antibody index, performed real-time polymerase chain reaction (PCR to detect JCV DNA in plasma and urine, and investigated the role of ultrasensitive C-reactive protein (usCRP as a possible biological marker of JCV reactivation. 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. Normalized optical density values were higher in urinary JCV DNA-positive patients (P<0.0001. Interestingly, the level of usCRP was higher in urinary JCV DNA-positive patients and correlated to the number of DNA copies in urine (P=0.028. As expected, patients' age correlated with JCV seropositivity and with JC viruria (P=0.02 and P=0.001, respectively. JC viruria was significantly correlated with a high JCV antibody index and high serum usCRP levels. We suggest that PCR and

    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.

    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

    Periodontal treatment may improve the metabolic control of dyslipidemia. The aim of this study was to evaluate the lipid profile and high-sensitivity C-reactive protein (hs-CRP) levels in obese and non-obese patients undergoing periodontal therapy. Patients with generalized chronic periodontitis were divided into obese (n = 28) and non-obese groups (n = 26). The periodontal parameters (visible plaque index, gingival bleeding index, probing depth, clinical attachment level, and bleeding on probing), anthropometric measurements (body mass index, waist circumference, and body fat), and serum analyses (triglycerides, total cholesterol, high-density lipoprotein, low-density lipoprotein, fasting glucose, glycated hemoglobin, and hs-CRP) were measured at baseline and 90 days after periodontal treatment. The results showed that the obese subjects presented alterations in triglycerides, total cholesterol, low-density lipoprotein, and hs-CRP at baseline when compared with non-obese patients (P 0.05). Obese subjects showed a significant decrease in the levels of triglycerides, total cholesterol, low-density lipoprotein, and hs-CRP post-therapy (P Lipid profile was modified only in obese patients post-therapy.

    Full Text Available C-reactive protein, a conserved acute-phase protein synthesized in the liver and involved in inflammation, infection, and tissue damage, is an informative biomarker for human cardiovascular disease. Out of 258 captive adult common chimpanzees (Pan troglodytes assayed for CRP, 27.9% of the data were below the quantitation limit. Data were analyzed by the Kaplan-Meier method and results compared to other methods for handling censored data (including deletion, replacement, and imputation. Kaplan-Meier results demonstrated a modest age effect and a strong effect of HCV infection in reducing CRP but did not allow inference of reference intervals. Results of other methods varied considerably. Substitution schemes differed widely in statistical significance, with estimated group means biased by the size of the substitution constant, while inference of unbiased reference intervals was impossible. Single imputation gave reasonable statistical inferences but unreliable reference intervals. Multiple imputation gave reliable results, for both statistical inference and reference intervals, and was comparable to the Kaplan-Meier standard. Other methods should be avoided. CRP did not predict cardiovascular disease, but CRP levels were reduced by 50% in animals with hepatitis C infection and showed inverse relationships with 2 liver function enzymes. Results suggested that hsCRP can be an informative biomarker of chronic hepatic dysfunction.

    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)

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.

    [Purpose] We investigated the effect of low-intensity pulsed ultrasound and cryotherapy on joint function recovery and C-reactive protein (CRP) levels of patients with total knee replacement. [Subjects] Forty-six patients with total knee replacement were recruited and allocated to either low-intensity pulsed ultrasound therapy (n=15), cryotherapy (n=15), or a combination of both (n=16). Therapy was administered once a day, 5 times a week for 3 weeks. To determine functional joint recovery and reduction of inflammation, changes in the Korean Western Ontario and McMaster Universities Arthritis Index (K-WOMAC), range of motion (ROM), and CRP were assessed postsurgically and four times over a 3-week period. Using one-way analysis of variance (ANOVA), homogeneity tests were performed based on participants' general characteristics. To recognize changes in time-variant K-WOMAC, ROM, and CRP values between groups, repeated measures ANOVA was performed, and Tukey's test was used for post-test analysis. Values at α=0.05 were considered significant. [Results] We found a difference between groups and times, and the group that received the combined therapies showed greater changes in outcomes than the group that received low-intensity pulsed ultrasound therapy alone. [Conclusion] Applying both low-intensity pulsed ultrasound and cryotherapy can relieve inflammation and enhance joint function in patients who undergo total knee replacement.

    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 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

    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.

    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.

    Full Text Available OBJECTIVE: Chronic inflammation is considered as one of the contributing mechanisms of lower urinary tract symptoms (LUTS. Serum C-reactive protein (CRP level is the widely used biomarker of inflammatory status. This study investigated the association between serum CRP level in men with benign prostatic hyperplasia (BPH and lower urinary tract symptoms (LUTS before and after medical treatment. METHODS: A total of 853 men with BPH and LUTS were enrolled. All patients completed the International Prostate Symptoms Score (IPSS questionnaire and urological examinations. The parameters of uroflowmetry (maximum flow rate, Qmax; voided volume, VV, post-void residual (PVR, total prostate volume (TPV and transition zone index (TZI, serum prostate specific antigen (PSA, and serum CRP levels were obtained. All patients were treated with alpha-blocker or antimuscarinic agent based on the IPSS voiding to storage subscore ratio (IPSS-V/S. Correlation analyses were performed between serum CRP levels with age, IPSS, TPV, TZI, Qmax, PVR, VV, PSA and between baseline and post treatment. RESULTS: The mean age was 66.9 ± 11.6 years old and the mean serum CRP levels were 0.31 ± 0.43 mg/dL. Univariate analyses revealed serum CRP levels were significantly associated with age (p<0.001, PSA levels (p = 0.005 and VV (p = 0.017, but not significantly associated with TPV (p = 0.854 or PVR (p = 0.068. CRP levels were positively associated with urgency (p<0.001 and nocturia (p<0.001 subscore of IPSS, total IPSS (p = 0.008 and storage IPSS (p<0.001 and negatively associated with IPSS- V/S ratio (p = 0.014. Multivariate analyses revealed that serum CRP levels were significantly associated with age (p = 0.004 and storage IPSS subscore p<0.001. Patients with IPSS-V/S<1 and treated with tolterodine for 3 months had significant decrease of CRP levels after treatment. CONCLUSION: Serum CRP levels are associated with storage LUTS and sensory bladder disorders, suggesting chronic

    2014-01-01

    Full Text Available Background: Periodontal tissues mount an immune inflammatory response to bacteria and their products. Certain inflammatory cytokines produced during periodontal inflammation increase the production of acute phase proteins like high-sensitivity C-reactive protein (hs-CRP and can depress erythropoietin production leading to the development of anemia. Aim: The aim of this study is to investigate the efficacy of nonsurgical periodontal therapy on red blood cell (RBC parameters and hs-CRP in chronic periodontitis patients with anemia. Materials and Methods: This is a longitudinal, interventional study with 6-month follow-up. A total of 30 subjects with anemia and chronic periodontitis with age group of 33-55 years were selected by screening hemoglobin (Hb levels and examining periodontal findings. The clinical parameters plaque index (PI, gingival index (GI, probing pocket depth (PPD and clinical attachment level (CAL were recorded at baseline. Laboratory blood investigations were performed to evaluate RBC count, Hb, packed cell volume (PCV, erythrocyte sedimentation rate (ESR and red cell indices, hs-CRP at baseline. Nonsurgical periodontal therapy was performed for all patients. Patients were recalled after 6 months. The clinical and hematological parameters were re-evaluated to analyze the changes after nonsurgical periodontal therapy. Results: The results showed that there was a significant increase in Hb levels, RBC count and PCV from baseline to 6 months after nonsurgical periodontal therapy. There is significant decrease in levels of ESR and hs-CRP levels after nonsurgical periodontal therapy indicating resolution of periodontal inflammation. There is a significant decrease in PPD, scores of PI and GI and significant increase in CAL gain. Minimal changes in mean corpuscular volume, mean corpuscular hemoglobin (MCH and MCH concentration indicated that the lower values of red cell parameters are not due to any vitamin and mineral deficiencies

    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 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

    Background Many clinical studies suggest the inverse relationship between testosterone levels and insulin sensitivity in men, however the causative relationship of these two events is still not determined. The purpose of this study was to investigate the effects of testosterone replacement therapy (TRT) on insulin sensitivity, body composition, serum lipid profiles and high sensitivity C-reactive protein (hsCRP) in hypogonadotropic hypogonadal (HH) puberty undeveloped male patients.Methods In this prospectively designed study, we compared homeostasis model assessment of insulin resistance (HOMA-IR), insulin areas under the curves (AUC) of 3-hour oral glucose tolerance test (OGTT) and other metabolic parameters between 26 HH patients and 26 healthy men. The patients' HOMA-IR, insulin AUC, body composition, lipid profiles, hsCRP and other parameters were compared before and after nine-month TRT.Results The average levels of total testosterone (TT) in HH and healthy group were (0.9±0.6) nmol/L and (18.8±3.4) nmol/L, respectively. HOMA-IR in HH group was significantly higher than the healthy group (5.14±5.16 vs 2.00±1.38, P<0.005). Insulin AUC in 3-hour OGTT in HH group was significantly higher than the healthy group (698.6±414.7 vs 414.2±267.5, P<0.01). Fasting glucose level in HH group was significantly higher than control group ((5.1±0.6) mmol/L vs (4.7±0.3) mmol/l, P<0.005). Height, weight and grasp strength of the patients were significantly increased after 9-month TRT.

    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.

  1. 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.

    This study assessed the relationship between magnesium status and C-reactive protein concentration in obese and nonobese women. This cross-sectional study included 131 women, aged between 20 and 50 years, who were divided into two groups: obese (n=65) and control (n=66) groups. Magnesium intake was monitored using 3-day food records and NutWin software version 1.5. The plasma, erythrocyte, and urinary magnesium concentrations were determined by flame atomic absorption spectrophotometry. C-reactive protein concentration in serum was measured by immunoturbidimetric assay. The mean values of the magnesium content in the diet were lower than those recommended, though there was no significant difference between groups (p>0.05). The mean concentrations of plasma and erythrocyte magnesium were within the normal range, with no significant difference between groups (p>0.05). Urinary excretion of this mineral was less than the reference values in both groups, with no significant difference (p>0.05). The mean concentration of serum C-reactive protein was within the normal range in both groups, with no significant difference (p>0.05). There was a positive correlation between urinary magnesium and serum C-reactive protein (p=0.015). Obese patients ingest low dietary magnesium content, which seems to induce hypomagnesuria as a compensatory mechanism to keep plasma concentrations of the mineral at adequate levels. The study shows a positive correlation between urinary magnesium concentrations and serum C-reactive protein, suggesting the influence of hypomagnesuria on this inflammatory protein in obese women.

    Bacterial infection causes Sepsis which is one of the leading cause of mortality in hospitals. This infection can be quantified from blood plasma using C - reactive protein (CRP). A quick diagnosis at the patient's location through Point-of- Care (POC) testing could give doctors the confidence to prescribe antibiotics. In this paper, the development and testing of a bead-based procedure for CRP quantification is described. The size of the beads enable them to be trapped in wells without the need for magnetic methods of immobilization. Large (1.5 mm diameter) Polyamide nylon beads were used as the substrate for capturing CRP from pure analyte samples. The beads captured CRP either directly through adsorption or indirectly by having specific capture antibodies on their surface. Both methods used fluorescent imaging techniques to quantify the protein. The amount of CRP needed to give a sufficient fluorescent signal through direct capture method was found suitable for identifying bacterial causes of infection. Similarly, viral infections could be quantified by the more sensitive indirect capture method. This bead-based assay can be potentially integrated as a disposable cartridge in a POC device due to its passive nature and the small quantities needed.

    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).

    C-reactive proteins (CRP) constitute a ubiquitous and highly conserved family of calcium binding, pentameric plasma proteins. Although the precise biological function of CRP is uncertain, known properties suggest a role in host defence. The structure determination aims to elucidate key structural aspects of the interaction of CRP with specific biological ligands, leading towards the ultimate determination of the biological function. The initial and often rate limiting step in biological crystallography is the reproducible growth of well ordered crystals. Human CRP has been crystallised in two tetragonal forms (P4[sub 1]22 (form I) and P4[sub 2]22 (form II)) with closely similar unit cells, often twinned together. Heterogeneity due to dissociation of the oligomer is identified as a major factor limiting reproducible crystal growth. Other problems, of the large unit cell (>300[angstrom]), weak diffraction and extreme sensitivity to X-rays, have been overcome using the intense Synchrotron Radiation Source (SRS) at the S.E.R.C. Daresbury Laboratory. X-ray data sets to 3.1[angstrom] and 3.75[angstrom] resolution have been collected from the form I and form II crystals, respectively. Rotation function studies identify a pentamer in almost identical orientations in both crystal forms, and an artefactual 52 molecular pseudo-symmetry at low resolution. Despite extensive screening, structure determination has been delayed by the lack of suitable heavy atom derivatives. The analogous CRP from the invertebrate Limulus polyphemus has been crystallised in six polymorphic forms, two of which are suitable for structure analysis. Synchrotron X-ray data extending to 3.1[angstrom] have been collected from small crystals ([approximately]0.1mm) of one form. Rotation function analyses corroborate the 222 molecular point group symmetry prescribe by the crystal packing.

    C-reactive protein (CRP) is a risk marker for type 2 diabetes mellitus and cardiovascular diseases. In polycystic ovary syndrome (PCOS), limited data are available on high-sensitivity C-reactive protein (hs-CRP) levels and its relationship with components of PCOS especially in Indian women. The objective was to determine serum hs-CRP concentration in adolescent women with and without PCOS and to assess possible correlations of serum hs-CRP levels with components of PCOS in Indian women. One hundred and sixty women with PCOS and sixty non-PCOS women having normal menstrual cycles were included. Clinical assessment included anthropometry, Ferriman-Gallwey (FG) score and blood pressure (BP) measurement. Laboratory evaluation included estimation of T4, TSH, LH, FSH, total testosterone, prolactin, cortisol, 17OHP, hs-CRP, lipid profile, and insulin, and glucose after 2-h oral glucose tolerance test. Homeostasis Model Assessment Insulin resistance index (HOMA-IR) and Quantitative Insulin Sensitivity Check Index (QUICKI) and glucose intolerance was calculated. FG score, LH, FSH, total Testosterone, HOMA-IR and QUICKI were significantly different among women with or without PCOS (p PCOS, there was no significant difference between the groups (p > 0.05). A significant and positive correlation was found between hs-CRP and body mass index (BMI) (r = 0.308, p PCOS group. The results in Indian adolescent women suggest that hs-CRP levels may not per se be associated with PCOS, rather can be related to fat mass in this subset of subjects.

    Marte C Liefaard

    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.

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 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 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 There is substantial evidence that chronic renal and cardiovascular diseases are associated with coagulation disorders, endothelial dysfunction, inflammation and fibrosis. Angiotensin-Converting Enzyme Insertion/Deletion polymorphism (ACE I/D polymorphism has also be linked to cardiovascular diseases. Therefore, this study aimed to compare plasma levels of ultrassensible C-reactive protein (usCRP, PAI-1, D-dimer and TGF-β1 in patients undergoing HD with different ACE I/D polymorphisms.The study was performed in 138 patients at ESRD under hemodialysis therapy for more than six months. The patients were divided into three groups according to the genotype. Genomic DNA was extracted from blood cells (leukocytes. ACE I/D polymorphism was investigated by single polymerase chain reaction (PCR. Plasma levels of D-dimer, PAI-1 and TGF-β1 were measured by enzyme-linked immunosorbent assay (ELISA, and the determination of plasma levels of usCRP was performed by immunonephelometry. Data were analyzed by the software SigmaStat 2.03.Clinical characteristics were similar in patients with these three ACE I/D polymorphisms, except for interdialytic weight gain. I allele could be associated with higher interdialytic weight gain (P = 0.017. Patients genotyped as DD and as ID had significantly higher levels of PAI-1 than those with II genotype. Other laboratory parameters did not significantly differ among the three subgroups (P = 0.033. Despite not reaching statistical significance, plasma levels of usCRP were higher in patients carrying the D allele.ACE I/D polymorphisms could be associated with changes in the regulation of sodium, fibrinolytic system, and possibly, inflammation. Our data showed that high levels of PAI-1 are detected when D allele is present, whereas greater interdialytic gain is associated with the presence of I allele. However, further studies with different experimental designs are necessary to elucidate the mechanisms involved in these

    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.

Indeed, the level of systemic inflammation as measured by circulating levels of C-reactive protein (CRP has been linked to prognosis in patients with atherosclerotic disease, congestive heart failure, atrial fibrillation, myocarditis, aortic valve disease and heart transplantation. In addition, a number of basic science reports suggest an active role for CRP in the athophysiology of cardiovascular diseases. This article explores the potential role of CRP in disease initiation, progression, and clinical manifestations and reviews its role in the prediction of future events in clinical practice. Therapeutic interventions to decrease circulating levels of CRP are also reviewed.

    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 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. PMID:26177029

    2004-01-01

    Inflammation is an important component of active atherosclerotic disease. C-reactive protein (CRP)is a non-specific inflammatory marker that is increased in inflammatory conditions. Newer more sensitive assays (high sensitivity CRP) can detect the low levels of inflammation associated with vascular disease. CRP levels can give further risk assessment to individuals beyond predictions from traditional risk factors. This measurement is most useful in helping to discriminate risk in intermediate risk patients such as metabolic syndrome patients. Exercise and weight loss have been shown to significantly lower CRP levels. Lipid lowering therapies, especially with the statin class of medications, also lower CRP levels. A reduction in inflammation may be an important component of plaque stabilization and contribute to cardiovascular risk reduction.

    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.

    BACKROUND: Some researches demonstrate that high-sensitivity C-reactive protein may be a risk factor to cause carotid atherosclerosis in patients with cerebral infarction. Inflammatory reaction may participate in formation of carotid atherosclerosis in patients with acute cerebral infarction.OBJECTIVE: To investigate the correlation between levels of serum high-sensitivity C-reactive protein and carotid atherosclerosis in patients with acute cerebral infarction accompanied with carotid atherosclerosis.DESIGN: Contrast observation between two groups.SETTING: Department of Neurology, Zhenzhou Hospital, Shenyang Medical College.PARTICIPANTS: A total of 102 patients with acute cerebral infarction regarded as cerebral infarction group were selected from Department of Neurology, Shenzhou Hospital Affiliated to Shenyang Medical College from February 2005 to September 2006. There were 55 males and 47 females and their ages ranged from 55 to 86 years. All patients met the variously diagnostic points of cerebral infarction established by the Fourth National Cerebrovascular Disease Academic Meeting and were finally diagnosed with CT or MRI examination. Illness course was in an acute phase. A total of 96 healthy subjects were regarded as control group, including 51 males and 45 females aged from 48 to 78 years. All accepted subjects provided the confirmed consent.METHODS: ① Patients in the cerebral infarction group received carotid ultrasound Doppler examination and serum high-sensitivity C-reactive protein detection within 72 hours after onset. IMMAGE immune biochemical system and latex reinforcement particle-enhanced nephelometric immunoassay (PENIA) were used for quantitative detection of serum high-sensitivity C-reactive protein. ② Healthy subjects in the control group received the same detection. SEQUOIA512 color Doppler ultrasound (Siemens Company,USA) was used to detect carotid artery of all subjects so as to observe intima media thickness of artery and formation of

    Cardiovascular risk persists despite intensive low-density lipoprotein cholesterol (LDL-C) reduction using statins. High-density lipoprotein (HDL-C) is inversely associated with coronary artery disease (CAD) that is independent of LDL-C levels. C-reactive protein (CRP) is an established marker of inflammation that can impair the protective function of HDL-C: however, the impact of inflammation on the association between HDL-C and long-term outcomes in patients with CAD under statin therapy remains uncertain. We prospectively enrolled 3,507 consecutive patients with CAD who underwent a first percutaneous coronary intervention (PCI) from 1997 to 2011 at our institution. We stratified 1,682 patients (48%) who had been treated with statin at the time of PCI into 4 groups according to HDL-C levels (cutoffs of 40 and 50 mg/dl for men and women, respectively) and a CRP cutoff of 2 mg/dl: (1) high HDL-C/low CRP, (2) high HDL-C/high CRP, (3) low HDL-C/low CRP, and (4) low HDL-C/high CRP comparing the rates of all-cause death among them. The median follow-up period was 1,985 days (interquartile range 916 to 3,183 days). During this period, 197 patients (11.7%) died because of cardiac death (n = 58), carcinoma (n = 61), stroke (n = 10), and other causes (n = 69). The rates of all-cause death significantly differed among the groups (log-rank test, p <0.0001). In multivariate Cox hazard regression analyses, low HDL-C with high CRP levels remained significantly associated with a higher rate of all-cause death even after adjustment for other co-variates (hazard ratio 2.38, 1.59 to 3.61, p <0.0001). Low HDL-C together with elevated CRP levels is significantly associated with long-term outcomes in patients who received statin therapy after PCI.

    CONTEXT: Obesity is associated with short telomere length. The cause of this association is unknown. OBJECTIVE: We hypothesized that genetically increased body mass index (BMI) is associated with telomere length shortening and that low-grade inflammation might contribute through elevated C......-reactive protein. SETTING AND DESIGN: We studied 45,069 individuals from the Copenhagen General Population Study with measurements of leukocyte telomere length, BMI, and C-reactive protein in a Mendelian randomization study. Using the three obesity-associated polymorphisms FTO rs9939609, MC4R rs17782313, and TMEM......18 rs6548238, and the CRP promoter polymorphism rs3091244 in instrumental variable analyses, we estimated the associations between genetically increased BMI and telomere length and between genetically increased C-reactive protein and telomere length.

    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

    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.

    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 mm{sup 2}, 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. In this prospective study with patients with ACS, the predominant components of the culprit plaque were fibrotic and necrotic core. Serum hs C-reactive protein levels did not correlate with plaque composition.

    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. Higher mean hs-CRP values were associated with poor outcome after acute ischemic stroke. P<0.001.

    Background It is unclear whether elevated plasma C reactive protein (CRP) is causally related to chronic obstructive pulmonary disease (COPD). The authors tested the hypothesis that genetically elevated plasma CRP causes COPD using a Mendelian randomisation design. Methods The authors measured high...... versus a doubling of genetically elevated CRP resulted in ORs for COPD of 1.27 (95% CI 1.25 to 1.30) versus 1.01 (0.81 to 1.26) and for COPD hospitalisation of 1.47 (1.43 to 1.51) versus 0.82(0.59 to 1.13). Conclusion Although elevated CRP is related to both a diagnosis of COPD and subsequent hospital...... admission, genetically elevated plasma CRP is not associated with an increased risk of clinical COPD. This suggests that the association between CRP levels and COPD is not causal....

    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.

    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.

    Objectives: The purpose of this study was to analyze how anti-infectious periodontal treatment affects C reactive protein (CRP) values in patients with type 1 diabetes, and correlate baseline CRP levels with periodontal disease severity. Study Design: A cohort of fifty three subjects with type 1 diabetes and moderate to severe periodontitis were recruited. Periodontal parameters were measured, and blood samples were obtained to evaluate high-sensitivity C-reactive protein (hs-CRP). Group 1 was treated with scaling, root planning, and systemic administration of doxycycline. Group 2 received only scaling and root planning. Results: Hs-CRP was reduced after periodontal treatment in group 1 (-0.22 mg/l) and 2 (-0.21 mg/l ) but this reduction was not statistically significant, even in the patients with the best response to periodontal treatment. However, significant correlation appeared between hs-CRP and mean probing pocket depth (PPD) (p=0, 01) and mean clinical attachment level (CAL) (p=0,03). Conclusions: Non-surgical periodontal treatment couldn’t reduce hs-CRP values, however, it was found an association between advanced periodontitis and elevated blood hs-CRP levels in patients with type 1 diabetes. It can be speculated that periodontal disease increases production of pro-inflammatory mediators in patients with type 1 diabetes, but other producing sources of these pro-inflammatory substances may exist. Key words:Periodontal disease, periodontitis, diabetes mellitus type 1, periodontal therapy, C reactive protein. PMID:22322513

    Elevated plasma concentration of C-reactive protein has emerged as an important predictor of future cardiovascular diseases and metabolic abnormalities in apparently healthy individuals. Obese individuals tend to have elevated C-reactive protein concentrations. Weight loss induces a change in this protein, and single nucleotide polymorphisms in regulating genes might affect this change, since C-reactive protein concentration is known to be approximately 40-50% heritable. Our aim was to study the association between the IL6 -174(G/C), IL1B +3,954(C/T) and CRP +1,059(G/C) single nucleotide polymorphisms, and CRP concentrations in obese men during a weight reduction program. We genotyped 72 obese men who had participated in a weight reduction program. Their C-reactive protein concentrations, interleukin-6 levels and fat mass were determined at two time points: at baseline and after weight reduction (after 2 months). After weight reduction, the mean weight loss was 14.3 kg. Median C-reactive protein concentrations decreased, after weight reduction, from 1.72 to 1.22 mg/l (p polymorphisms studied were not associated with CRP concentrations. Our results show that, at baseline, there is no difference in C-reactive protein concentrations among the different IL6-174(G/C) genotypes, but after weight loss the CC genotype is associated with highest C-reactive protein concentrations, resulting from the fact that C-reactive protein seems not to decrease with weight loss in this genotype.

  18. 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.

    Full Text Available Introduction: Low sensitivity and specificity in traditional laboratory tests became insufficient for accurate diagnostics and initiation of proper treatment of patients infected with bacterial meningitis. High sensitivity C reactive protein (hsCRP may be an appropriate supplement for rapid diagnosis of bacterial meningitis. The subject of our investigation was the determination of C- reactive protein in cerebrospinal fluid (CSF duringacute bacterial meningitis.Methods: HsCRP was analysed by a sensitive immunoturbidimetric assay using the Dimension RxL analyser (Siemens. Cerebrospinal fluid concentrations of C-reactive protein have been measured in 20 patients(age range,1 to 50 years presenting with acute bacterial meningitis and also in a non-infected, non-inflamed control group (n=25.Results: The accuracy and precision of the method proved to be satisfactory. Repeatability of serial sampling for hsCRP described by coefficient of variation were CV=2.1-4.5%. This assay hsCRP in cerebrospinal fluid demonstrates adequate performance characteristics for routine clinical use. Elevated levels of CRP were found in 95% patients with bacterial meningitis. The mean CRP value in 25 uninfected control group was 0.25 mg/L (range 0.10-0.55. The mean CRP for patients with bacterial meningitis was 21.4 mg/L (range 0.40-100.Conclusions: A sensitive assay for CRP in CSF would be an useful adjunct to conventional investigation of acute infective meningitis.

    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

    Objective We assessed thelevels of C-reactive protein ( CRP ) in patients with acute coronary syndrome (ACS) [including unstable angina pectoris (UAP), acute myocardial infarction (AMI) and sudden cardiac death (SCD) ] compared with non-ACS [including stable angina pectoris (SAP), old myocardial infarction (OMI) and healthy volunteers] and sought to test whether CRP are associated with clinical acute coronary syndrome. Methods Ultrasensitive immunoassay (rate nephelometry with the Beckman Array multitest immunoassay system) wasused to measure CRP levels in 91 patients with ACS(20 UAP, 71 AMI including 2 SCD) and non-ACS (34SAP, 25 patients with healing phase of AMI, 41 OMI and 94 control healthy subjects) Results CRP levels were higher in ACS group (18.50 + 23.98 mg/L [ SE 2.51, n = 91 ] ) compared with non - ACS group (3.89+7.14mg/L[SE0.51, n=194]) (P <0.01).Using Logistic Regression, CRP was a potent determinant of ACS ( OR = 1.65) Conclusion These results suggest that CRP has a strong association with ACS, and CRP is a risk factor of ACS.

    INTRODUCTION    Increased C-reactive protein (CRP) concentrations during pregnancy are associated with several perinatal complications. OBJECTIVES    The aim of the study was to assess serum CRP concentrations and identify its determinants in pregnant women with type 1 diabetes. PATIENTS AND METHODS    CRP concentrations were determined using a high-sensitivity assay (hs-CRP) in the first trimester (I, week change between mid-pregnancy and the late third trimester (5.7 mg/l [2.5-9.6 mg/l]). CRP concentrations in all 3 trimesters were positively correlated with the waist‑to-hip ratio (I, P resistance, namely, the estimated glucose disposal rate, assessed in the first trimester (I, P = 0.01; II, P = 0.0165; III, P = 0.0062). There was a positive correlation between the levels of hs-CRP and total cholesterol (P = 0.001), low-density lipoprotein cholesterol (P = 0.013), and triglycerides (P = 0.0014) in the first trimester. There was no significant correlation between CRP and hemoglobin A1c, daily insulin requirement/kg, high-density lipoprotein cholesterol levels, maternal age, and diabetes duration. CONCLUSIONS    Adiposity, abnormal body fat distribution, and insulin resistance are the major determinants of CRP concentrations in pregnant women with type 1 diabetes. Our results confirm the importance of weight control before pregnancy in women with type 1 diabetes. PMID:27073847

    Full Text Available The distinction between exudates and transudates is very important in the patient management. Here we evaluate whether the acute-phase protein serum amyloid A (SAA, in comparison with C reactive protein (CRP and total protein (TP, can be useful in this discrimination. CRP, SAA, and TP were determined in 36 exudate samples (27 pleural and 9 ascitic and in 12 transudates (9 pleural and 3 ascitic. CRP, SAA, and TP were measured. SAA present in the exudate corresponded to 10 % of the amount found in serum, that is, the exudate/serum ratio (E/S was 0.10 ± 0.13 . For comparison, the exudate/serum ratio for CRP and TP was 0.39 ± 0.37 and 0.68 ± 0.15 , respectively. There was a strong positive correlation between serum and exudate SAA concentration ( r = 0.764 ; p < 0.0001 . The concentration of SAA in transudates was low and did not overlap with that found in exudates (0.02-0.21 versus 0.8–360.5un g/mL. SAA in pleural and ascitic exudates results mainly from leakage of the serum protein via the inflamed membrane. A comparison of the E/S ratio of SAA and CRP points SAA as a very good marker in discriminating between exudates and transudates

    The metabolic syndrome (MS) is defined by the clustering of a number of cardiovascular risk factors. The aims of the present study were to estimate the prevalence of MS in Madrid (Spain) by 2 definitions and to investigate its relationship with several sociodemographic factors and C-reactive protein (CRP) levels. This was a cross-sectional population study, and participants were 1344 subjects aged 31 to 70 years. Clinical evaluation included data on sociodemographic and cardiovascular background, physical examination, fasting glucose, triglycerides, and high-density lipoprotein cholesterol. The CRP levels were determined in a subgroup of 843 subjects. The diagnosis of MS was made according to the 2005 Adult Treatment Panel III (ATP III) and International Diabetes Federation (IDF) definitions. The age- and sex-adjusted prevalence of MS was 24.6% (95% confidence interval [CI], 22.3%-26.9%) using the ATP III definition and 30.9% (95% CI, 28.4%-33.3%) using the International Diabetes Federation definition. The overall agreement rate was 91.5% (kappa = 0.80; 95% CI, 0.76-0.83). Prevalence figures by both definitions were higher in men than in women and increased with age. Male sex, older age, low educational level, and physical inactivity were all determinants of ATP III-defined MS. The presence of MS or any of its components was associated with high CRP levels. In a logistic regression analysis, low educational level and waist circumference were the best predictors for high CRP level. The prevalence of MS in the Madrid region is one of the highest in Europe and confirms the strong Spanish regional variability in this syndrome frequency. Some sociodemographic and lifestyle factors, particularly educational level, are predictors for MS and high CRP levels.

    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.

    Myocardial infarction is a relevant cardiovascular event worldwide for morbidity and mortality. It has been theorized that acute myocardial infarctions (AMIs) and other acute coronary events that are precipitated by atherosclerosis are due to arterial blockage from fat deposits. It is now known, however, that atherosclerosis involves more than just lipids. Inflammation has also been studied extensively to play a substantial role in myocardial infarction. There have been debates and conflicting reports over the past few years about the value of assessing levels of C-reactive protein and other biomarkers of inflammation for the prediction of cardiovascular events. Several studies have shown that CRP is not only an inflammatory marker, but also involved in the pathogenesis of myocardial infarction. Studies have linked atherogenesis and rupture of atherosclerotic lesion to endothelial dysfunction. CRP directly inhibits endothelial cell nitric oxide (NO) production via destabilizing endothelial NO synthase (eNOS). Decreased NO release causes CRP mediated inhibition of angiogenesis, stimulating endothelial cell apoptosis. CRP can also activate the complement system through the classical pathway. Complement activation plays an important role in mediating monocyte and neutrophil recruitment in an injured myocardium and may therefore lead to increase in infarct size. This article discusses the possible roles of CRP in complement activation, endothelial dysfunction and its impact on the development of myocardial infarction. We also reviewed the possible therapeutic approaches to myocardial infarction.

    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.

    Full Text Available Post-stroke fatigue is a common and distressing problem but little is known about its biological mechanisms. This cohort study was to investigate associations between C-reactive protein (CRP and fatigue after stroke.Patients were assessed at one, six and 12 months after their stroke onset, with the Fatigue Assessment Scale, a case definition of post-stroke fatigue, Hospital Anxiety and Depression Scale, and daily step counts. Blood samples were collected at each assessment and the CRP level was determined by a standard CRP immunoassay. Cross-sectional associations between CRP and fatigue at each time point were determined by Pearson correlation coefficient and independent-samples t-test. Whether CRP levels at one month predict fatigue scores at six and 12 months was explored by multiple linear regression, with anxiety, depression, and daily step counts as covariates.Sixty-five patients (mean age 67 years, 65% men were included: 61 at one month, 49 at six months, and 41 at 12 months. CRP levels and fatigue scores were not associated at one month (p = 0.88 or 12 months (p = 0.56, but weakly associated at six months (r = 0.27, p = 0.04; however, this association was no longer significant (p = 0.14 after controlling for the effects of covariates. The CRP level was not associated with the fulfilment of case definition of post-stroke fatigue at any time points (all p > 0.05. The CRP level at one month was not a significant predictor for fatigue levels at either six months (p = 0.93 or 12 months (p = 0.78.There is insufficient evidence for the association between CRP and PSF in stroke patients. Future studies with larger sample sizes and controlling for potential confounders are needed to investigate whether this association exists.

  4. 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)

    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

    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...

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.

    Acute kidney injury (AKI) is exacerbated in C-reactive protein transgenic mice but alleviated in Smad3 knockout mice. Here we used C-reactive protein transgenic/Smad3 wild-type and C-reactive protein transgenic/Smad3 knockout mice to investigate the signaling mechanisms by which C-reactive protein promotes AKI. Serum creatinine was elevated, and the extent of tubular epithelial cell necrosis following ischemia/reperfusion-induced AKI was greater in C-reactive protein transgenics but was blunted when Smad3 was deleted. Exacerbation of AKI in C-reactive protein transgenics was associated with increased TGF-β/Smad3 signaling and expression of the cyclin kinase inhibitor p27, but decreased phosphorylated CDK2 and expression of cyclin E. Concomitantly, tubular epithelial cell proliferation was arrested at the G1 phase in C-reactive protein transgenics with fewer cells entering the S-phase cell cycle as evidenced by fewer bromodeoxyuridine-positive cells. In contrast, the protection from AKI in C-reactive protein transgenic/Smad3 knockout mice was associated with decreased expression of p27 and promotion of CDK2/cyclin E-dependent G1/S transition of tubular epithelial cells. In vitro studies using tubular epithelial cells showed that C-reactive protein activates Smad3 via both TGF-β-dependent and ERK/MAPK cross talk mechanisms, Smad3 bound directly to p27, and blockade of Smad3 or the Fc receptor CD32 prevented C-reactive protein-induced p27-dependent G1 cell cycle arrest. In vivo, treatment of C-reactive protein transgenics with a Smad3 inhibitor largely improved AKI outcomes. Thus, C-reactive protein may promote AKI by impairing tubular epithelial cell regeneration via the CD32-Smad3-p27-driven inhibition of the CDK2/cyclin E complex. Targeting Smad3 may offer a new treatment approach for AKI. PMID:27470679

    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

    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

    A radiometric ligand binding assay for human C-reactive protein (CRP) was established using pneumococcal C polysaccharide (CPS) coupled to magnetizable cellulose particles as the solid phase ligand. Competition for binding to the solid phase between 125I-CRP and unlabelled CRP permitted detection of 30 micrograms/l of CRP and the precise assay of concentrations up to 3000 micrograms/l. Identical results were obtained when the assay was used to quantitate isolated pure CRP and pure CRP added to normal human serum. However in vitro addition of known ligands for CRP to acute phase serum resulted in lowering of the apparent CRP concentration in this assay and addition of as little as 1 microgram/l of free CPS or 1 mg/l of lecithin was demonstrable in this way. A combination of the ligand binding assay and the standard electroimmunoassay for CRP was therefore used to test acute phase sera for the presence of CRP complexed in vitro. No evidence of complexed CRP was detected among sera containing between 1-319 mg/l of CRP from patients with Hodgkin's disease (10), rheumatoid arthritis (10), Crohn's disease (19) and various microbial infections (11), including six with subacute bacterial endocarditis. Since it is likely that CRP does form complexes with its ligands in the plasma these results suggest that complexed CRP is rapidly cleared from the circulation.

    Background The data on the prognostic values of high sensitivity C-reactive protein (hsCRP) levels in patients with advanced symp-tomatic heart failure (HF) receiving cardiac resynchronization therapy (CRT) are scarce. The aim of present study was to investigate the association of serum hsCRP levels with left ventricle reverse remodeling after six months of CRT as well as long-term outcome. Methods A total of 232 CRT patients were included. The assessment of hsCRP values, clinical status and echocardiographic data were performed at baseline and after six months of CRT. Long-term follow-up included all-cause mortality and hospitalizations for HF. Results During the mean follow-up periods of 31.3 ± 31.5 months, elevated hsCRP (>3 mg/L) prior to CRT was associated with a significant 2.39-fold increase (P=0.006) in the risk of death or HF hospitalizations. At 6-month follow-up, patients who responded to CRT showed significant reductions or maintained low in hsCRP levels (–0.5 ± 4.1 mg/L reduction) compared with non-responders (1.7 ± 6.1 mg/L increase, P=0.018). Com-pared with patients in whom 6-month hsCRP levels were reduced or remained low, patients in whom 6-month hsCRP levels were increased or maintained high experienced a significantly higher risk of subsequent death or HF hospitalizations (Log-rank P<0.001). The echocardio-graphic improvement was also better among patients in whom 6-month hsCRP levels were reduced or remained low compared to those in whom 6-month hsCRP levels were raised or maintained high. Conclusions Our findings demonstrated that measurement of baseline and follow-up hsCRP levels may be useful as prognostic markers for timely potential risk stratification and subsequent appropriate treatment strategies in patients with advanced HF undergoing CRT.

    C-reactive protein (CRP) is an inflammatory biomarker of inflammation and may reflect progression of vascular disease. Conflicting evidence suggests CRP may be a prognostic biomarker of ischemic stroke outcome. Most studies that have examined the relationship between CRP and ischemic stroke outcome have used mortality or subsequent vascular event as the primary outcome measure. Given that nearly half of stroke patients experience moderate to severe functional impairments, using a biomarker like CRP to predict functional recovery rather than mortality may have clinical utility for guiding acute stroke treatments. The primary aim of this study was to systematically and critically review the relationship between CRP and long-term functional outcome in ischemic stroke patients to evaluate the current state of the literature. PubMed and MEDLINE databases were searched for original studies which assessed the relationship between acute CRP levels measured within 24 hours of symptom onset and long-term functional outcome. The search yielded articles published between 1989 and 2012. Included studies used neuroimaging to confirm ischemic stroke diagnosis, high-sensitivity CRP assay, and a functional outcome scale to assess prognosis beyond 30 days after stroke. Study quality was assessed using the REMARK recommendations. Five studies met all inclusion criteria. Results indicate a significant association between elevated baseline high sensitivity CRP and unfavorable long-term functional outcome. Our results emphasize the need for additional research to characterize the relationship between acute inflammatory markers and long-term functional outcome using well-defined diagnostic criteria. Additional studies are warranted to prospectively examine the relationship between high sensitivity CRP measures and long-term outcome.

    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.

    Septic arthritis has to be suspected in children with joint effusion and fever so as to perform joint aspiration, which will confirm the diagnosis by bacteriological methods, and to perform surgical treatment by joint lavage. Since development of current molecular methods, such as real-time PCR, Kingella kingae has become the first microbial agent of osteoarticular infections in young children, whereas Staphylococcus aureus is second. C-reactive protein (CRP) is an aid used to diagnose septic arthritis, but its elevation could be moderate. In a previous study, conducted at our hospital, 10% of children hospitalized for S. aureus or K. kingae septic arthritis had a CRP levelseptic arthritis could be made by other parameters, we analyzed the clinical and biologic features of these patients and compared them to those of children hospitalized for septic arthritis with initial CRP ≥10 mg/L. Among the 89 children with septic arthritis, 10% (n=9) had initial CRPseptic arthritis had no fever, CRP elevation, or fibrinogen elevation. In the CRP-negative group, three of four children with S. aureus arthritis and one of five with K. kingae arthritis had a high CRP level (34, 40, 61, and 13 mg/L, respectively) 3 days after surgery and antibiotic treatment. One child with K. kingae septic arthritis and initial CRParthritis. In the S. aureus arthritis group, none of the children with initial CRP10 mg/L during septic arthritis in children, it could be negative in up to 20% of patients in different studies. However, a mild inflammatory syndrome or even a CRPseptic arthritis. Therefore, a first episode of monoarthritis in children has to be considered as septic arthritis and treatment should not be delayed.

    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.

    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.

    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 NaAsO{sub 2} 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

    AIM: To determine the effect of procedural and clinical factors upon C reactive protein (CRP) dynamics following transcatheter aortic valve implantation (TAVI). METHODS: Two hundred and eight consecutive patients that underwent transfemoral TAVI at two hospitals (Imperial, College Healthcare NHS Trust, Hammersmith Hospital, London, United Kingdom and San Raffaele Scientific Institute, Milan, Italy) were included. Daily venous plasma CRP levels were measured for up to 7 d following the procedure (or up to discharge). Procedural factors and 30-d safety outcomes according to the Valve Academic Research Consortium 2 definition were collected. RESULTS: Following TAVI, CRP significantly increased reaching a peak on day 3 of 87.6 ± 5.5 mg/dL, P < 0.001. Patients who developed clinical signs and symptoms of sepsis had significantly increased levels of CRP (P < 0.001). The presence of diabetes mellitus was associated with a significantly higher peak CRP level at day 3 (78.4 ± 3.2 vs 92.2 ± 4.4, P < 0.001). There was no difference in peak CRP release following balloon-expandable or self-expandable TAVI implantation (94.8 ± 9.1 vs 81.9 ± 6.9, P = 0.34) or if post-dilatation was required (86.9 ± 6.3 vs 96.6 ± 5.3, P = 0.42), however, when pre-TAVI balloon aortic valvuloplasty was performed this resulted in a significant increase in the peak CRP (110.1 ± 8.9 vs 51.6 ± 3.7, P < 0.001). The development of a major vascular complication did result in a significantly increased maximal CRP release (153.7 ± 11.9 vs 83.3 ± 7.4, P = 0.02) and there was a trend toward a higher peak CRP following major/life-threatening bleeding (113.2 ± 9.3 vs 82.7 ± 7.5, P = 0.12) although this did not reach statistical significance. CRP was not found to be a predictor of 30-d mortality on univariate analysis. CONCLUSION: Careful attention should be paid to baseline clinical characteristics and procedural factors when interpreting CRP following TAVI to determine their future management. PMID

    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.

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

    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.

    We demonstrate the application of a multilaminar flow platform, in which functionalized magnetic particles are deflected through alternating laminar flow streams of reagents and washing solutions via an external magnet, for the rapid detection of the inflammatory biomarker, C-reactive protein (CRP). The two-step sandwich immunoassay was accomplished in less than 60 s, a vast improvement on the 80-300 min time frame required for enzyme-linked immunosorbent assays (ELISA) and the 50 min necessary for off-chip magnetic particle-based assays. The combination of continuous flow and a stationary magnet enables a degree of autonomy in the system, while a detection limit of 0.87 μg mL(-1) makes it suitable for the determination of CRP concentrations in clinical diagnostics. Its applicability was further proven by assaying real human serum samples and comparing those results to values obtained using standard ELISA tests.

    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.

    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

    Objectives Pregnancy and lactation involve adaptations in immune regulation, but little is known about cross-cultural variation in inflammatory changes during pregnancy or lactation. Here we report concentrations of C-reactive protein (CRP) in a large cross-sectional sample of healthy Filipino women who vary in parity, gestational and lactational status, and who come from a population previously described as having low CRP. Methods Fasting plasma CRP was measured among female participants (ages 20.8-22.4 years) in the Cebu Longitudinal Health and Nutrition Survey (n=822). Results Median CRP was 0.2 mg/L in nulliparous women and peaked at 2.0 mg/L in women in their 3rd trimester of pregnancy. Parous but post-partum women had higher CRP compared to nulliparous women, which was largely explained by body composition differences as reflected in waist circumference and skinfold measures. Among post-partum women with infants, CRP was similar in women who were currently breastfeeding compared to those who were not. Conclusions At Cebu, women late in gestation have 10-fold higher C-reactive protein compared to nulliparous women, with no evidence that lactation is inflammatory. These population-based findings are similar with findings from prior clinic-based studies and are consistent with the maternal immunological adaptations initiated during pregnancy. The tendency of human females to spend more time than females of other great apes in gestation rather than lactation suggests that the human life history strategy involved increased time spent by reproductively aged females in a pro-inflammatory state.

    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

    Full Text Available BACKGROUND: The metabolic syndrome (MetS is a cluster of cardiovascular risk factors, which includes abdominal obesity, hypertension, hyperglycemia, dyslipidemia, and insulin resistance. Recent evidence implicates inflammation in the development of insulin resistance and MetS. Evidence has emerged demonstrating that high concentrations of h igh - sensitive C - reactive protein (hsCRP are associated with MetS and may predict diabetes and cardiovascular events, independent of traditional risk factors. It has also been suggested that hsCRP may be included in the criteria for MetS. OBJECTIVES OF THE STUDY: To study the significance of high sensitivity C - reactive protein as a biochemical marker in metabolic syndrome. To correlate high sensitivity C - reactive protein titres with fasting plasma glucose, body mass index, blood pressure, waist circumferen ce, triglyceride and high density cholesterol levels. MATERIALS AND METHODS: 50 cases and 50 controls were taken into the study. Cases were selected according to new IDF criteria. RESULTS: In the present study, there were 23 males & 27 females in each study group with mean Age distribution of 48.32±14.2 among cases and 48.12±14.1 among controls. Mean BMI in our study was 30.48±1.76 among cases and 23.42±1.52 among controls, with all cases meeting criteria for metabolic syndrome according to new IDF criteria. In our study 84% of cases were hypertensives, 10% of controls had systolic Blood . Pressure >130mmHg. 82% of cases were known diabetics on treatment. 82.6% of cases (M ales had HDL 3, 88% of controls had hsCRP <3. Age, waist, circumference, BMI, SBP, DBP, FBS, TG levels correlated positively whereas HDL levels correlated negatively with hsCRP levels. CONCLUSIONS: There is a positive association between increasing age and the increase in pre valence of metabolic syndrome . Waist circumference and BMI correlated positively with hsCRP values, implying that obesity plays an important role in

    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.

    In this article, we examine the distribution of a marker of immune system stimulation-C-reactive protein-in urban Brazil. Social relationships are associated with immunostimulation, and we argue that cultural dimensions of social support, assessed by cultural consonance, are important in this process. Cultural consonance is the degree to which individuals, in their own beliefs and behaviors, approximate shared cultural models. A measure of cultural consonance in social support, based on a cultural consensus analysis regarding sources and patterns of social support in Brazil, was developed. In a survey of 258 persons, the association of cultural consonance in social support and C-reactive protein was examined, controlling for age, sex, body mass index, low-density lipoprotein cholesterol, depressive symptoms, and a social network index. Lower cultural consonance in social support was associated with higher C-reactive protein. Implications of these results for future research are discussed.

    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....

    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

    Study Objectives: Increasing evidence suggests that alterations in sleep duration are associated with cardiovascular disease (CVD) and mortality. Additionally, sleep disordered breathing (SDB), which is associated with disturbed nighttime sleep and hypoxemia, may be an independent risk factor for CVD. The inflammatory marker, C-reactive protein (CRP), is an important predictor of CVD. We investigated potential associations between circulating CRP, sleep duration, and SDB. Design: Cross-sectional Study. Population: Participants were 907 adults from the Wisconsin Sleep Cohort Study (WSCS). Measurements and Results: CRP was measured after overnight polysomnography. The relationships between CRP and sleep parameters were evaluated using multiple linear regression with and without controlling for age, sex, and body mass index (BMI) and other potential confounders. CRP was found to be higher for women and had a strong positive correlation with age and BMI. CRP showed a significant positive association with current smoking, waist-hip ratio (WHR), LDL-cholesterol, triglycerides, leptin, and insulin, independent of age, sex, and BMI. Significant independent negative associations for CRP were observed with HDL-cholesterol (HDL), insulin sensitivity (quantitative insulin sensitivity check index [QUICKI]), and hours of exercise. There was a significant positive association between CRP levels and the apnea-hypopnea index (AHI, the measure of SDB), but these relationships were not significant after adjustment for age, sex, and BMI. No significant association between CRP levels and measures of sleep duration (polysomnographic and self-reported) were found. Conclusion: There was no significant association between CRP levels and sleep duration. The lack of an independent association between CRP levels and SDB suggests that the reported relationship between these 2 variables may be primarily driven by their association with obesity.

    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.

    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

    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.

    Linkage analysis has identified a susceptibility locus for type 2 diabetes mellitus (T2DM) on chromosome 1q21-q23 in several populations. Results from recent prospective studies indicate that increased levels of C-reactive protein (CRP), a marker of immune system activation, are predictive...... of diabetes, independent of adiposity. Because CRP is located on 1q21, we considered it a potential positional candidate gene for T2DM. We therefore evaluated CRP and the nearby serum amyloid P-component, APCS, which is structurally similar to CRP, as candidate diabetes susceptibility genes. Approximately 10......, a surrogate measure of insulin secretion in non-diabetic subjects (P=0.050). Linkage analyses that adjusted for the effect of these polymorphisms indicated that they do not in themselves account for the observed linkage with T2DM on chromosome 1q.

    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.

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

    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.

    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.

    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

    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.

    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.

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

    We assessed the technical performance and robustness of the point-of-care test for C-reactive protein (CRP) NycoCard CRP for use in forensic autopsy cases. The results of 17 of 39 cadaver blood samples that had CRP in the range effectively measured by the NycoCard (5-120mg/l) correlated well (r=0.99) with those of quantitative latex agglutination immunoassay (turbidimetry), and the out-of-range NycoCard results were fully consistent with those obtained by turbidimetry. For the ten sera whose CRP >120mg/l according to NycoCard, a significant correlation (r=0.98) was observed between values multiplied by the dilution ratio and those of turbidimetry. No significant differences were observed after a freeze-thaw procedure. In addition, CRP results using recombinant human CRP spiked with hemoglobin up to 80g/l were not significantly different from the unspiked results in PBS. The test allows reliable and cost-effective on-site measurement of CRP from a small volume of serum (5μl) with simple equipment. This semi-quantification method of CRP should be useful for diagnosis during autopsy.

    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.

    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.

    Severe peritonitis causing death is one of the most devastating complications of peritoneal dialysis (PD). Since the predictive value of C-reactive protein (CRP) in PD fluid has not been assessed, the objective of the present study is to evaluate its predictive value and clinical correlation in patients on PD with peritonitis. One hundred and twenty patients on continuous ambulatory PD (CAPD) were enrolled and their serum and fluid CRP (Fl. CRP) were evaluated at the start of CAPD. All patients who developed peritonitis were further evaluated for serum and fluid CRP. The patients were categorized into four groups, namely: normal patients (control group), patients with peritonitis, patients with peritonitis leading to catheter removal, and death due to peritonitis. Sixty-five patients developed peritonitis of whom, catheter removal was performed in eight patients. Five patients died due to peritonitis-related complications. Fl. CRP showed a significant difference among the three groups, unlike S. CRP. Estimation of CRP in the peritoneal fluid may be a useful marker to monitor the onset of peritonitis.

    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.

    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.

    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.

    Most proinflammatory actions of C-reactive protein (CRP) are only expressed following dissociation of its native pentameric assembly into monomeric form (mCRP). However, little is known about what underlies the greatly enhanced activities of mCRP. Here we show that a single sequence motif, i.e. cholesterol binding sequence (CBS; a.a. 35-47), is responsible for mediating the interactions of mCRP with diverse ligands. The binding of mCRP to lipoprotein component ApoB, to complement component C1q, to extracellular matrix components fibronectin and collagen, to blood coagulation component fibrinogen, and to membrane lipid component cholesterol, are all found to be markedly inhibited by the synthetic CBS peptide but not by other CRP sequences tested. Likewise, mutating CBS in mCRP also greatly impairs these interactions. Functional experiments further reveal that CBS peptide significantly reduces the effects of mCRP on activation of endothelial cells in vitro and on acute induction of IL-6 in mice. The potency and specificity of CBS are critically determined by the N-terminal residues Cys-36, Leu-37, and His-38; while the versatility of CBS appears to originate from its intrinsically disordered conformation polymorphism. Together, these data unexpectedly identify CBS as the major recognition site of mCRP and suggest that this motif may be exploited to tune the proinflammatory actions of mCRP.

    Ten men with classic rheumatoid arthritis were studied for 23 days in Badgastein, Austria, in August, 1980. One man (patient 07) showed a marked increase of disease activity after a few days. C-reactive protein (CRP) concentrations increased from 8.7 mg/dl on day 2 to 13.0 mg/dl on day 16. CRP values expressed as percent mean of a day showed a significant circadian rhythm with the acrophase at -30 degrees. For the same patient we also found significant circadian rhythms in grip strength and pearl stringing with acrophases in the evening and a circadian rhythm in walking time with the acrophase in the early morning. Seven of the ten men in the study had elevated CRP concentrations during the 3 weeks of observation. Population-mean cosinor results of CRP, grip strength, pearl stringing, and walking time revealed acrophases similar to the single cosinor results of patient 07. Our results suggest that inflammation in rheumatoid arthritis is a circadian rhythmic process with lowest disease activity in the evening.

    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.

    Complement-mediated inflammation exacerbates the tissue injury of ischaemic necrosis in heart attacks and strokes, the most common causes of death in developed countries. Large infarct size increases immediate morbidity and mortality and, in survivors of the acute event, larger non-functional scars adversely affect long-term prognosis. There is thus an important unmet medical need for new cardioprotective and neuroprotective treatments. We have previously shown that human C-reactive protein (CRP), the classical acute-phase protein that binds to ligands exposed in damaged tissue and then activates complement, increases myocardial and cerebral infarct size in rats subjected to coronary or cerebral artery ligation, respectively. Rat CRP does not activate rat complement, whereas human CRP activates both rat and human complement. Administration of human CRP to rats is thus an excellent model for the actions of endogenous human CRP. Here we report the design, synthesis and efficacy of 1,6-bis(phosphocholine)-hexane as a specific small-molecule inhibitor of CRP. Five molecules of this palindromic compound are bound by two pentameric CRP molecules, crosslinking and occluding the ligand-binding B-face of CRP and blocking its functions. Administration of 1,6-bis(phosphocholine)-hexane to rats undergoing acute myocardial infarction abrogated the increase in infarct size and cardiac dysfunction produced by injection of human CRP. Therapeutic inhibition of CRP is thus a promising new approach to cardioprotection in acute myocardial infarction, and may also provide neuroprotection in stroke. Potential wider applications include other inflammatory, infective and tissue-damaging conditions characterized by increased CRP production, in which binding of CRP to exposed ligands in damaged cells may lead to complement-mediated exacerbation of tissue injury.

    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

    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

  15. 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.

    C-Reactive protein (CRP) plays an important role in the acute phase response. Transcripts encoding two new CRP-like molecules (ccCRP1 and ccCRP2) from European common carp have been characterized which has enabled seven CRP-like genes to be identified in zebrafish. 79.3% (ccCRP1) and 74.5% (ccCRP2) identity to CRP from East-Asian common carp occurs and fish CRP genes form a distinct clade. ccCRP2 gene organization comprises four exons and three introns, in contrast to the two exons/one intron organization of mammalian CRP genes. Gene expression assays showed both ccCRP-like molecules are constitutively expressed in liver, skin, gill, gut, muscle, kidney, spleen and blood. Protein levels of ccCRP in serum and spleen were significantly different from other organs analyzed, and levels were greatest in the liver. It is proposed that the two carp CRP genes defined differ in their expression profiles which may suggest differences in their biological activities.

    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.

    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

    Social experiences can affect the relationship between depression and physical health. The current study examined how social support from parents and friends may moderate the association of depressive symptoms with hypothalamic-pituitary-adrenal (HPA) axis activity and C-reactive protein among adolescents (N=316, Mage=16.40, SD=.74; 57% female) from diverse ethnic backgrounds (23.1% Asian, 29.1% European, 41.8% Latino, and 6.0% other backgrounds). Results indicated that parent support, but not friend support, moderated the link between depressive symptoms and both total daily cortisol output (a measure HPA activity) and C-reactive protein (a marker of inflammation). These patterns did not differ by ethnicity. Overall, the study highlights the continued, and perhaps accumulated, importance of parents during adolescence despite increasing needs for autonomy from and exploration outside of the family unit.

    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

    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.

    The main cause of death in rheumatoid arthritis (RA) is cardiovascular events. We evaluated the relationship of anticyclic citrullinated peptide (anti-CCP) antibody levels with increased carotid intima-media thickness (cIMT) in RA patients. Methods. Forty-five anti-CCP positive and 37 anti-CCP negative RA patients, and 62 healthy controls (HC) were studied. All groups were assessed for atherogenic index of plasma (AIP) and cIMT. Anti-CCP, C-reactive protein (CRP), and levels of tumor necrosis factor alpha (TNFα) and interleukin-6 (IL-6) were measured by enzyme-linked immunosorbent assay (ELISA). Results. The anti-CCP positive RA patients showed increased cIMT compared to HC and anti-CCP negative (P < 0.001). Anti-CCP positive versus anti-CCP negative RA patients, had increased AIP, TNFα and IL-6 (P < 0.01), and lower levels of high density lipoprotein cholesterol (HDL-c) (P = 0.02). The cIMT correlated with levels of anti-CCP (r = 0.513, P = 0.001), CRP (r = 0.799, P < 0.001), TNFα (r = 0.642, P = 0.001), and IL-6 (r = 0.751, P < 0.001). In multiple regression analysis, cIMT was associated with CRP (P < 0.001) and anti-CCP levels (P = 0.03). Conclusions. Levels of anti-CCP and CRP are associated with increased cIMT and cardiovascular risk supporting a clinical role of the measurement of cIMT in RA in predicting and preventing cardiovascular events.

We evaluated the relationship of anticyclic citrullinated peptide (anti-CCP antibody levels with increased carotid intima-media thickness (cIMT in RA patients. Methods. Forty-five anti-CCP positive and 37 anti-CCP negative RA patients, and 62 healthy controls (HC were studied. All groups were assessed for atherogenic index of plasma (AIP and cIMT. Anti-CCP, C-reactive protein (CRP, and levels of tumor necrosis factor alpha (TNFα and interleukin-6 (IL-6 were measured by enzyme-linked immunosorbent assay (ELISA. Results. The anti-CCP positive RA patients showed increased cIMT compared to HC and anti-CCP negative (P<0.001. Anti-CCP positive versus anti-CCP negative RA patients, had increased AIP, TNFα and IL-6 (P<0.01, and lower levels of high density lipoprotein cholesterol (HDL-c (P=0.02. The cIMT correlated with levels of anti-CCP (r=0.513, P=0.001, CRP (r=0.799, P<0.001, TNFα (r=0.642, P=0.001, and IL-6 (r=0.751, P<0.001. In multiple regression analysis, cIMT was associated with CRP (P<0.001 and anti-CCP levels (P=0.03. Conclusions. Levels of anti-CCP and CRP are associated with increased cIMT and cardiovascular risk supporting a clinical role of the measurement of cIMT in RA in predicting and preventing cardiovascular events.

    The complement inhibitor factor H (fH) interacts via its seventh short consensus repeat (SCR) domain with multiple ligands including heparin, streptococcal M protein and C-reactive protein (CRP). The aim of this study was to localize the residues in SCR 7 required for these interactions. We initially built a homology model of fH SCR 6-7 using the averaged NMR structures of fH SCR 15-16 and vaccinia control protein SCR 3-4 as templates. Electrostatic potentials of the model's surface demonstrated a co-localization of three clusters of positively charged residues on SCR 7, labeled site A (R369 and K370), site B (R386 and K387) and site C (K392). These residues, localized to the linker region preceding SCR 7 and to the end of a "hypervariable loop" in SCR 7, were systematically replaced with uncharged alanine residues in an fH construct containing SCR 1-7. The resulting proteins were expressed in the methylotrophic yeast, Pichia pastoris. By ELISA analysis we demonstrated: first, that substituting site A inhibited heparin and CRP binding; secondly, that substituting site B inhibited binding to heparin, CRP and M protein; and thirdly, that substituting site C clearly inhibited only heparin binding.

    We evaluated whether sepsis severity and C-reactive protein (CRP) level on admission prognostically corroborated or annulled each other in adult patients with incident community-acquired bacteremia (Funen, Denmark, 2000-2008). We used logistic regression and area under the receiver operating...... characteristic curve (AUC) to evaluate 30-day mortality in four models: (i) age, gender, comorbidity, bacteria, and ward. (ii) Model 1 and sepsis severity. (iii) Model 1 and CRP. (iv) Model 1, sepsis severity, and CRP. Altogether, 416 of 1999 patients died within 30 days. CRP independently predicted 30-day...... mortality [Model 4, odds ratio (95% CIs) for 100 mg/L: 1.16 (1.06-1.27)], but it did not contribute to the AUC (Model 2 vs Model 4: p = 0.31). In the 963 non-severe sepsis patients, CRP independently predicted 30-day mortality [Model 4: 1.42 (1.20-1.69)] and it increased the AUC (Model 2 vs Model 4: p = 0...

    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.

    Johnson, A Myron; Ledue, Thomas B; Collins, Marilyn F

    2003-02-01

    Certified Reference Material 470 (CRM 470) demonstrates commutability with both the manufacturer's calibrator and with dilutions of serum pools in the Dade Behring N High Sensitivity assay for C-reactive protein (CRP). Both regression and back calibration show similar nonlinearity for all materials, largely due to the method of calibration curve fitting used in this assay. Significant differences in values among the currently available commercial assays can be largely overcome by using appropriate calibration curve fitting and the recommended value transfer protocol, which includes a minimum of two assay runs on each of at least 3 separate days, with weight correction of all reconstitutions and dilutions. An initial weight-corrected dilution should be made each day because of the relatively high level of CRP in CRM 470. In our opinion, the degree of nonlinearity, imprecision, and differences in values in currently available assays renders the use of fixed clinical decision cut-points questionable for high-sensitivity CRP. An alternative approach is suggested.

    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.

    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.

    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

    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.

    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 Objective: C-reactive protein (CRP is considered to be a cardiovascular risk marker and changes in its level have been attributed to genetic factors. The aim of the study was to determine CRP 1059G/C gene polymorphism frequency and its relationship with CRP levels and carotid artery intima-media thickness (CIMT in type 2 diabetic patients (DM. Materials and Methods: One hundred and sixty-four type 2 diabetic patients (mean age: 57±7 years; F/M: 80/84 and 151 controls (mean age: 53±7 years; F/M: 81/70 were recruited. CIMT was assessed by carotid ultrasonography. CRP 1059G/C polymorphism was determined by polymerase chain reaction and restriction fragment length polymorphism analyses. Results: The CRP 1059G/C polymorphism distribution in diabetic group and controls were similar (1059GG in 92% vs. 88%, 1059GC in 2% vs. 5%; 1059CC in 6% vs. 7%. CRP levels (4.3±6.6 mg/L vs. 2.5±2.3 mg/L; p=0.02 and CIMT (0.67±0.18mm vs. 0.56±0.19mm; p<0.0001 were increased in diabetics compared to controls. No association of CRP and CIMT with CRP 1059G/C polymorphism was found. Conclusions: Increased CRP levels and CIMT seem to be independent of CRP 1059G/C gene polymorphism in our group of type 2 diabetic patients. Turk Jem 2010; 14: 85-8

    Prior research has found inconsistent evidence regarding the association among childhood adversity, inflammation, and internalizing symptoms, perhaps because previous studies have yet to adequately integrate important factors such as the timing of the adversity, genetic variation, and other relevant processes such as neuroendocrine regulation. The aims of the present study were threefold: (a) to determine whether the effect of the timing of child maltreatment on C-reactive protein (CRP), an inflammatory marker, varies by CRP gene variation; (b) to explore whether links between salivary CRP and childhood internalizing symptoms depend on the presence and timing of maltreatment experiences; and (c) to investigate the role of CRP in the relations between child neuroendocrine regulation and internalizing symptoms and examine whether these associations are moderated by the presence and timing of child maltreatment. Participants included a sample of 267 maltreated and 222 nonmaltreated children (M age = 9.72, SD = 0.99; 52.4% male; 66% African American) who attended a summer day camp research program designed for school-aged low-income children. Department of Human Services records were examined to determine the onset and recency of maltreatment for children in the maltreated group. The results indicated that among children with recent onset maltreatment, those with at least one A allele from CRP single nucleotide polymorphism rs1417938 evidenced significantly higher CRP levels compared to recently maltreated children carrying the TT genotype. Moreover, higher levels of CRP were associated with higher levels of internalizing symptoms only for recently maltreated children. Finally, we did not find support for salivary CRP as a mechanism in the relation between neuroendocrine regulation and childhood internalizing symptoms. Our findings highlight the importance of the timing of child maltreatment and have important implications for characterizing variability in inflammation

    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.

    Inflammation may initiate and promote breast cancer development, and be associated with elevated circulating levels of inflammation markers. A total of eight 130 initially healthy women, participated in the population-based Tromsø study (1994-2008). Pre-diagnostic high-sensitivity C-reactive protein (hs-CRP) was assessed. During 14.6 years of follow-up, a total of 192 women developed invasive breast cancer. These cases were followed for additional 7.2 years. Detailed medical records were obtained. We observed an overall positive dose-response relationship between pre-diagnostic hs-CRP and breast cancer risk (hazard ratio (HR) = 1.06, 95 % CI 1.01-1.11). Postmenopausal women with above median levels of hs-CRP (>1.2 mg/l) had a 1.42 (95 % CI 1.01-2.00) higher breast cancer risk compared to postmenopausal women with hs-CRP below median. Postmenopausal women, who were hormone replacement therapy non-users, and were in the middle tertile (0.8-1.9 mg/l), or highest tertile of hs-CRP (>1.9 mg/l), had a 2.31 (95 % CI 1.31-4.03) and 2.08 (95 % CI 1.16-3.76) higher breast cancer risk, respectively, compared with women in the lowest tertile. For each unit increase in pre-diagnostic hs-CRP levels (mg/l), we observed an 18 % increase in disease-free interval (95 % CI 0.70-0.97), and a 22 % reduction in overall mortality (95 % CI 0.62-0.98). Our study supports a positive association between pre-diagnostic hs-CRP and breast cancer risk. In contrast, increased pre-diagnostic hs-CRP was associated with improved overall mortality, but our findings are based on a small sample size, and should be interpreted with caution.

Because of thevarious limitations of conventionally used laboratory techniques, we evaluatedand compared the diagnostic utility of C-reactive protein(CRP and lactatedehydrogenase (LDHin serum and cerebrospinal fluid (CSFin the diagnosisof bacterial meningitis and its effectivity in distinguishing it from asepticmeningitis (AP.Material and MethodsA total of 125 pediatric cases, aged between 1 month and 12 years, includingpatients with bacterial meningitis (n=45, aseptic meningitis (n=42 and acontrol group (n=38, were retrospectively analyzed on the basis of datafrom the initial clinical examinations. Cultures, smears and other commonserum and CSF indices were compared with serum and CSF CRP levels andLDH activity.ResultsCompared with each of the other variables, there were significant differencesin the mean values of serum-CRP, CSF-glucose, CSF-LDH and CSF/serumLDH ratio between the bacterial and aseptic meningitis groups (p<0.001.Of all the tests applied, the highest sensitivity (95% and negative predictivevalue (95% belonged to CSF-LDH activity and the most specific (100% testwith the highest positive predictive value (100% was CSF-CRP titration aswell as smear and culture. Combination of CSF-CRP serum-CRP, and CSFLDHyielded the highest sensitivity (100% and negative predictive value butthe combined application of CSF-LDH and CSF-CRP proved to be the mostspecific and efficient.ConclusionIn the presence of a normal CRP titration and low glucose level in CSF,bacterial meningitis is excluded, whereas elevated level of CSF-LDH activityis a valid confirmatory predictor of BM. In addition, combination of thesethree tests with serum CRP is far more effective than the separate determinationof any of these parameters.

Likewise, its potential value as a marker of severity, which is well established in patients with pneumonia, remains unproven in chronic obstructive pulmonary disease (COPD exacerbations. Methods: A cohort study of 118 patients with severe COPD and acute infectious exacerbations were included and followed up over 1 year. Episodes of exacerbations meeting Anthonisen’s criteria type I–II were evaluated, analyzing the etiology and inflammatory response as measured by CRP in blood. Results: A total of 380 episodes were recorded. Full microbiological analysis was available in 265 samples. Haemophilus influenzae was the most commonly isolated bacteria and rhinovirus the most common virus. Median CRP levels from the 265 episodes were higher in the cases with positive cultures for bacteria (58.30 mg/L, interquartile range [IQR] 21.0–28.2 than in episodes only positive for viruses (37.3 mg/L, IQR 18.6–79.1 and cases negative for any

    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.

    Background Pre-clinical studies link cannabinoid-1 receptor activation to inflammation and atherosclerotic effects; anti-inflammation and immunosuppression seem to be mediated by cannabinoid-2 receptor activation. In this epidemiological study, we aim to present estimates on suspected cannabis-attributable immunomodulation as manifest in serum C-reactive protein (CRP) levels as non-specific inflammatory markers with interpretable clinical values. With strength of data from recent large nationally representative community sample surveys, the research approach illustrates value of a quantile regressions approach in lieu of the commonly used but relatively arbitrary cutpoints for CRP values. Methods The study population encompasses 20–59 year old participants from the National Health and Nutrition Examination Surveys, 2005–2010 (n = 1115 recently active cannabis smokers and 8041 non-smokers, identified via confidential Audio Computer Assisted Self-Interviews). Age, sex, race, education, income-poverty ratio, alcohol consumption, and tobacco smoking also were measured, together with body mass index (BMI), which actually might be on a mediational path. Quantile regressions, with bootstrapping for variance estimation, made it possible to hold these covariates constant while estimating cannabis-CRP associations. Results Evidence suggesting possible cannabis-attributable immunomodulation emerges at CRP levels below the median (p<0.05). Whereas BMI might help explain a cannabis link with serum CRP, but BMI-stratified analyses disclosed no appreciable variation of the cannabis-CRP relationship across BMI subgroups. Conclusions Extending pre-clinical research on cannabis-attributable immunomodulation, this study’s CRP evidence points toward possible anti-inflammatory effects of cannabis smoking. More definitive evidence can be derived by combining pre-clinical research, studies of patients, and epidemiological research approaches. PMID:25529540

    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. Possible molecular mechanisms of metformin action–studied by gene expression profiling in the liver–revealed deregulated genes from inflammatory and insulin signaling, AMP

    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.

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

  18. 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 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.

  20. 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.

    Pyometra is a life-threatening reproductive disorder that affects the uterus of female dogs. This study was designed to identify the possible indicators of uterine inflammation by comparing C-reactive protein (CRP), serum amyloid A (SAA), and haptoglobin (Hp) concentrations in uterine arterial and peripheral venous blood in bitches with open- and closed-cervix pyometra. CRP, SAA, and Hp concentrations were higher in bitches with closed-cervix pyometra irrespective of the site of blood collection. Higher acute-phase protein concentrations were observed in peripheral compared with uterine arterial blood in bitches with closed-cervix pyometra, whereas the levels were comparable in dogs with open-cervix pyometra. Our results indicate that mean acute-phase protein concentrations differ according to pyometra type/severity and blood source and suggest the possible use of peripheral blood levels of CRP, SAA, and Hp to monitor inflammation during the course of pyometra.

    Full Text Available 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.

    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.

    Full Text Available Background and Objective: Magnetic nanobeads have a large surface- area-to-volume ratio, which is used for immobilized antibody. Using nanoparticles could increase the amount of antibodies in surface in comparison to ELISA. We investigated the ability of magnetic nanobeads to evaluate CRP by colorimetric method and compared the results with ELISA. Material and Methods: This study is an applicable research conducted in Tehran University of Medical Sciences, 2012. The Magnetic nanobeads conjugated by CRP antibodies were used to measure the protein in the concentration of 1-10 ng/ml (ELISA kit levels and 0.1 – 0.01 ng/ml. After antigen measurement, the results were compared with Mann Whitney test. Results: The results in concentration of 1-10 ng/ml are not significantly different (p = 0.78. But in concentrations of 0.1-0.01 ng/ml, the difference is significant (p= 0.02. Conclusion: The ability of Magnetic nanobeads in measurement of low concentration of antigen is 100 times better than ELISA. Thus Magnetic nanobead method is useful for early measurement and can easily be used in clinical laboratory. Keywords: CRP; Magnetic Nanobead; ELISA

    Full Text Available The local immunoreactivity of C-reactive protein (CRP was studied in a heterotopic porcine model of posttranplant obliterative bronchiolitis (OB. Bronchial allografts and control autografts were examined serially 2–28 days after subcutaneous transplantation. The autografts stayed patent. In the allografts, proliferation of inflammatory cells (P<.0001 and fibroblasts (P=.02 resulted in occlusion of the bronchial lumens (P<.01. Influx of CD4+ (P<.001 and CD8+ (P<.0001 cells demonstrated allograft immune response. CRP positivity simultaneously increased in the bronchial walls (P<.01, in macrophages, myofibroblasts, and endothelial cells. Local CRP was predictive of features characteristic of OB (R=0.456–0.879, P< .05−P<.0001. Early obliterative lesions also showed CRP positivity, but not mature, collagen-rich obliterative plugs (P<.05. During OB development, CRP is localized in inflammatory cells, myofibroblasts and endothelial cells probably as a part of the local inflammatory response.

  4. Magnetic permeability based diagnostic test for the determination of the canine C-reactive protein concentration in undiluted whole blood

    International Nuclear Information System (INIS)

    We describe an one-step 11-min magnetic permeability based two-site immunoassay for C-reactive protein (CRP) utilizing polyclonal anti-canine CRP antibody conjugated dextran iron oxide nanoparticles (79 nm) as superparamagnetic labels and polyclonal anti-canine CRP conjugated silica microparticles (15 to 40 μm) as carriers. An inductance based magnetic permeability reader was used to detect the target analyte, CRP, in 10 μL whole blood samples, by measuring the magnetic permeability increase of the silica microparticle sediment due to immuno complex superparamagnetic nanoparticles. Measurements on standards showed a linear response between 0 and 17.5 mg/L CRP. Measurements performed on 16 whole blood samples from mixed breeds showed good correlation with a commercially available ELISA assay.

    2015-01-01

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

    Full Text Available BACKGROUND: Acute myocardial infarction (AMI is one of cardiovascular diseases with high morbidity and mortality rates. Novel biomarkers that can detect accurately acute coronary syndrome (ACS at early stage, are necessary to improve current strategies and/or to identify subjects who are at risk. Fibrinogen and high-sensitivity C-reactive protein (hs-CRP roles in inflammation process could be potential for ACS early detection. This study was conducted to evaluate measurements of fibrinogen and hs-CRP on ACS. METHODS: An analytic observational study with cross sectional approach was conducted on patients with Troponin I positive. After signing informed consent, anamnesis and complete blood count were conducted. Besides that, liver function, renal function, and blood glucose tests were conducted as well. Samples of selected subjects were quantified with enzyme-linked immunosorbent assay (ELISA for Troponin I, fibrinogen and hs-CRP. Then statistical analyses were performed. RESULTS: There were 76 subjects in each ACS and non-ACS groups. ACS group showed significant higher levels of both fibrinogen and hs-CRP compared to Non-ACS group (p=0.000. Among evaluated risk factors, diabetes mellitus (DM (p=0.003 and hypertension (p=0.000 were significantly higher in ACS group than in non-ACS group. Among evaluated clinical factors, blood glucose (p=0.001 and age (p=0.000 were significantly higher in ACS group than in non-ACS group. Combination of fibrinogen and hs-CRP measurements showed the highest sensitivity (75.00%, specificity (80.26%, accuracy (77.63%, positive predictive value (79.19% and negative predictive value (76.25%. CONCLUSIONS: Since fibrinogen and hs-CRP were increased in ACS group and combination of fibrinogen and hs-CRP measurements showed the highest sensitivity, specificity, accuracy, positive predictive value and negative predictive value, we suggest that combination of fibrinogen and hs-CRP measurements could give added value to

    The aim of the study was to investigate the correlation between the levels of C-reactive protein (CRP) and chitinase 3-like protein 1 (YKL-40) in blood samples with morpohometric parameters of retinal blood vessels in patients with diabetic retinopathy. Blood laboratory examination of 90 patients included the measurement of glycemia, HbA1C, total cholesterol, LDL-C, HDL-C, triglycerides and CRP. Levels of YKL-40 were detected and measured in serum by ELISA (Micro VueYKL-40 EIA Kit, Quidel Corporation, San Diego, USA). YKL-40 correlated positively with diameter and negatively with number of retinal blood vessels. The average number of the blood vessels per retinal zone was significantly higher in the group of patients with mild non-proliferative diabetic retinopathy than in the group with severe form in the optic disc and all five retinal zones. The average outer diameter of the evaluated retinal zones and optic disc vessels was significantly higher in the group with severe compared to the group with mild diabetic retinopathy. Morphological analysis of the retinal vessels on digital fundus photography and correlation with YKL-40 may be valuable for the follow-up of diabetic retinopathy.

    Full Text Available Introduction: Periodontal disease (PD is a chronic inflammatory process that occurs in response to infection from bacteria in dental plaque. PD affects and destroys the periodontal tissues causing teeth loss. It is also associated to systemic diseases. C-reactive protein (CRP is a protein produced by the liver and released into the blood during the acute phase of inflammation. Therefore, CRP is very used as a marker for inflammation process. Studies on the presence of CRP in the saliva of the subjects with PD do not exist. Objective: The aim of this study was to test a biochemical kit for CRP detection in blood plasma to monitor CRP in saliva of PD subjects. Material and methods: Saliva was collected from 40 individuals, both sexes, from 20-45 years-old, divided into two groups: Test Group – PD subjects (TG; n = 20 and Control Group (CG n = 20, without PD. The following salivary parameters were analysed: buffer capacity (BC, salivary flow (SF, pH, urea, total proteins, and CRP. Results: pH, SF and BC values were considered normal in both groups. The urea concentration was higher in TG (27.4 mg/dl ± 10.03 than CG (22.9 mg/dl ± 8.3. However, the concentration of total proteins was higher in CG (201.2 ± 100 mg/dl than TG (155.0 ± 95 mg/dl. CRP was detected in 11 PD subjects and in eight subjects without PD. Conclusion: There were no significant differences between the two groups in relation to SF, pH and BC. However, in PD subjects’ saliva, urea values increased and total proteins decreased. The biochemical kit detected CRP in subjects’ saliva of both groups.

Materials and methods This investigation was a prospective double blinded clinical study. The study was done on 173 patients surgically treated for acute appendicitis. The WBC, NP, and measurement of CRP were randomly collected pre-operatively from all involved patients. Macroscopic assessment was made from the operation. Appendectomy and a histopathology examination were performed on all patients. Gross description was compared with histopathology results and then correlated with CRP, WBC, and NP. Results The observational accuracy was 87,3%, as compared to histopathological accuracy which was 85.5% with a total of 173 patients that were operated on. The histopathology showed 25 (14.5% patients had normal appendices, and 148 (85.5% patients had acutely inflamed, gangrenous, or perforated appendicitis. 52% were male and 48% were female, with the age ranging from 5 to 59 with a median of 19.7. The gangrenous type was the most frequent (52.6%. The WBC was altered in 77.5% of the cases, NP in 72.3%, and C-reactive protein in 76.9% cases. In those with positive appendicitis, the CRP and WBC values were elevated in 126 patients (72.8%, whereas NP was higher than 75% in 117 patients (67.6%. Out of 106 patients with triple positive tests, 101 (95.2% had appendicitis. The sensitivity, specificity, and positive predictive values of the 3 tests in combination were 95.3%, 72.2%, and 95.3%, respectively. Conclusion The raised value of the CRP was directly related to the severity of

However, detecting early heart failure in these patients is especially difficult because few objective measures have been validated in this cohort. The aim of this study is to determine the usefulness of high sensitivity C-reactive protein (hsCRP as a biomarker for detecting heart failure in univentricular heart disease patients, and to define the impact of univentricular morphology and stage of palliation on its utility. A cross-sectional observational study of children with univentricular congenital heart disease aged 1 month to 7 years was conducted. The presence of heart failure was defined as a Ross score > 2. The association of hsCRP with heart failure was assessed using logistic regression and receiver operating characteristic curves. Of the 50 included children, 16 (32% had clinical heart failure. A doubling of hsCRP resulted in a 0.31 unit increase in Ross score (95% confidence interval: –0.07, 0.56; P = 0.01 with a c-statistic of 68%. When stratified by ventricular morphology, the left univentricular morphology group exceeded the threshold of ≥75% (c-statistic = 81% as did those at stage II of palliation (c-statistic = 85%. A cut point of ≥0.8 mg/mL correctly classified 75% of patients with left univentricular morphology, and 73% of patients regardless of morphology at stage II of palliation. From these results, we conclude that hsCRP is a useful biomarker of clinical heart failure in univentricular patients with left ventricular morphology at all stages of surgical

    In an experimental infection model mimicking acute Actinobacillus pleuropneumoniae (Ap) infection in swine (Sus scrofa) by aerosol inoculation, the development of a number of typical clinical signs was accompanied by a prototypic acute phase reaction encompassing fever and an acute phase protein...... response peaking at around 2 days after infection. Haptoglobin, C-reactive protein (CRP), and major acute phase protein (MAP) responded with large increases in serum levels, preceding the development of specific antibodies by 4-5 days. Serum amyloid A protein (SAA) was also strongly induced. The increase......, kinetics of induction and normalization were different between these proteins. It is concluded that experimental Ap-infection by the aerosol route induces a typical acute phase reaction in the pig, and that pig Hp, CRP, MAP, and SAA are major acute phase reactants. These findings indicate the possibility...

    Background Procalcitonin (PCT) is an inflammatory marker that has been used as indicator of severe bacterial infection. We evaluated the concentrations of PCT as a marker for systemic infection compared to C-reactive protein (CRP) in patients neutropenic febrile. Methods 52 adult patients were enrolled in the study. Blood sample was collected in order to determine the serum concentrations of PCT, CRP and other hematological parameters at the onset of fever. The patients were divided into 2 groups, one with severe infection (n = 26) and the other in which the patients did not present such an infection (n = 26). Then PCT and CRP concentrations at the fever onset were compared between groups using non parametric statistical tests, ROC curve, sensitivity, specificity, likelihood ratio, and Spearman's correlation coefficient. Results The mean of PCT was significantly higher in the group with severe infection (6.7 ng/mL versus 0.6 ng/mL – p = 0.0075) comparing with CRP. Serum concentrations of 0.245 ng/mL of PCT displayed 100% de sensitivity and 69.2% specificity. PCT concentrations of 2,145 ng/mL presented a likelihood ratio of 13, which was not observed for any concentration of CRP. Conclusion PCT seems to be an useful marker for the diagnosis of systemic infection in febrile neutropenic patients, probably better than CRP. PMID:18034890

    Full Text Available The erythrocyte sedimentation rate (ESR and C-reactive protein (CRP are employed in the evaluation of patients with suspected septic arthritis, osteomyelitis, and acute rheumatic fever. The purpose of this study is to determine if one test has greater sensitivity (rises earlier than the other. Laboratory data were retrieved for pediatric patients hospitalized with one of the above three conditions, who had both ESR and CRP tests done on or shortly prior to admission. Sensitivity calculations were performed for mild, moderate, and severe degrees of ESR and CRP elevation. Microcytic erythrocytes, as defined by mean corpuscular volume (MCV less than 80 μL, were identified to see if this affects the ESR. ESR or CRP sensitivities depend on the cutoff value (threshold chosen as a positive test. The sensitivities were similar for similar degrees of elevation. ESR and CRP discordance was not significantly related to MCV. We concluded that the CRP does not rise earlier than the ESR (their sensitivities are similar. Previously published conclusions are dependent on arbitrary thresholds. We could not find any evidence that MCV affects the ESR.

    The inflammatory process plays an important role in the pathogenesis of many chronic diseases, such as cardiovascular diseases, diabetes mellitus type 2, and metabolic syndrome. Serum C-reactive protein (CRP) and interleukin-6 (IL-6) are widely tested inflammatory markers involved in the development of these diseases. Several studies indicate a relation between nutritional status and the concentrations of human high-sensitivity CRP and IL-6. Similarly, the role of diet in reducing inflammation and thereby modulating the risk of non-communicable diseases is supported by numerous studies. This review focuses on the effects of the selected nutrition models in humans on the concentrations of CRP and IL-6. It seems that the Mediterranean diet model is most effective in inhibiting inflammation. The Dietary Approaches to Stop Hypertension model and the plant nutrition model also have proven to be beneficial. The data on low-fat and low-carbohydrate diets are inconclusive. Comprehensive studies are necessary, taking into account the cumulative effect of dietary and other factors on the inflammatory process.

    Chronic obstructive pulmonary disease (COPD) is associated to cardiovascular morbidity and mortality, and abnormalities of the autonomic nervous system have been described in subjects with severe disease. We studied heart rate variability (HRV) in COPD patients at rest and during the 6-minute Walk Test (6mWT) and the association with lung function impairment taking into account systemic inflammation. Thirty outpatients with stable COPD underwent lung function measurements, blood gas analysis, ECG Holter and transcutaneous pulse oximetry during 6mWT and then they were classified by BODE index. Also C-reactive protein (CRP) was measured. At rest, we observed a significant reduction of HRV for increasing BODE index. During the 6mWT, HRV tended to decrease in BODE 1 subjects whereas an increase was observed in BODE 2 and BODE 3-4 subjects. Subjects with elevated CRP values had a significant reduction in Standard Deviation of all normal RR intervals at rest (SDNN: p = 0.013), Total Power (TFA: p = 0.04) and Very Low Frequency band (VLF: p = 0.041). At rest, subjects with Inspiratory Capacity-to-Total Lung Capacity ratio (IC/TLC) hyperinflation indices. At rest and during submaximal exercise, COPD patients with moderate and severe disease had an abnormal cardiac autonomic modulation which was related to both systemic inflammation and lung function impairment.

  2. High sensitivity C-reactive protein distribution in the elderly: the Bambuí Cohort Study, Brazil

    International Nuclear Information System (INIS)

    The measurement of the serum concentration of the acute-phase reactant C-reactive protein (CRP) provides a useful marker in clinical practice. However, the distribution of CRP is not available for all age and population groups. This study assessed the distribution of high sensitivity CRP (hs-CRP) by gender and age in 1470 elderly individuals from a Brazilian community that participates in the Bambuí Cohort Study. Blood samples were collected after 12 h of fasting and serum samples were stored at -70°C. Measurements were made with a commercial hs-CRP immunonephelometric instrument. More than 50% of the results were above 3.0 mg/L for both genders. Mean hs-CRP was higher in women (3.62 ± 2.58 mg/L) than in men (3.03 ± 2.50 mg/L). This difference was observed for all ages, except for the over-80 age group. This is the first population-based study to describe hs-CRP values in Latin American elderly subjects. Our results indicate that significant gender differences exist in the distribution of hs-CRP, and suggest that gender-specific cut-off points for hs-CRP would be necessary for the prediction of cardiovascular risks

    Full Text Available In addition to numerous immune factors, C-reactive protein (CRP and nitric oxide (NO are believed to be molecules of malaria immunopathology. The objective of this study was to detect CRP and NO inductions by agglutination latex test and Griess microassay respectively in both control and malaria groups from endemic areas of Iran, including Southeastern (SE (Sistan & Balouchestan, Hormozgan, Kerman and Northwestern (NW provinces (Ardabil. The results indicated that CRP and NO are produced in all malaria endemic areas of Iran. In addition, more CRP and NO positive cases were observed amongst malaria patients in comparison with those in control group. A variable co-association of CRP/NO production were detected between control and malaria groups, which depended upon the malaria endemic areas and the type of plasmodia infection. The percentage of CRP/NO positive cases was observed to be lower in NW compare to SE region, which may be due to the different type of plasmodium in the NW (Plasmodium vivax with SE area (P. vivax, Plasmodium falciparum, mixed infection. The fluctuations in CRP/NO induction may be consistent with genetic background of patients. Although, CRP/NO may play important role in malaria, their actual function and interaction in clinical forms of disease remains unclear.

    Wenbin Lu

    Full Text Available A novel photonic suspension array has been developed for multiplex immunoassay. The carriers of this array were silica colloidal crystal beads (SCCBs. The codes of these carriers have characteristic reflection peaks originating from their structural periodicity; therefore they do not suffer from fading, bleaching, quenching or chemical instability. In addition, the fluorescence background of SCCBs is negligible because no fluorescence materials or dyes are involved. With a sandwich method, the proposed suspension array was used for simultaneous multiplex detection of heart failure (HF and coronary heart disease (CAD biomarkers in one test tube. The results showed that the three biomarkers: cardiac troponin I (cTnI, C-reactive protein (CRP and B-type natriuretic peptide (BNP could be assayed in the ranges of 0.1-500 ng/ml, 1-500 mg/L and 0.02-50 ng/ml with detection limits of 0.01 ng/ml, 0.36 mg/L and 0.004 ng/ml at 3σ, respectively. There were no significant differences between the photonic suspension array and traditional parallel single-analyte test. This novel method demonstrated acceptable accuracy, high detection sensitivity and reproducibility and excellent storage stability. This technique provides a new strategy for low cost, automated, and simultaneous multiplex immunoassays of bio-markers.

    Wellington M. Fakanya

    2014-10-01

    Full Text Available The development of an electrochemical immunosensor for the biomarker, C-reactive protein (CRP, is reported in this work. CRP has been used to assess inflammation and is also used in a multi-biomarker system as a predictive biomarker for cardiovascular disease risk. A gold-based working electrode sensor was developed, and the types of electrode printing inks and ink curing techniques were then optimized. The electrodes with the best performance parameters were then employed for the construction of an immunosensor for CRP by immobilizing anti-human CRP antibody on the working electrode surface. A sandwich enzyme-linked immunosorbent assay (ELISA was then constructed after sample addition by using anti-human CRP antibody labelled with horseradish peroxidase (HRP. The signal was generated by the addition of a mediator/substrate system comprised of 3,3,5',5'-Tetramethylbenzidine dihydrochloride (TMB and hydrogen peroxide (H2O2. Measurements were conducted using chronoamperometry at −200 mV against an integrated Ag/AgCl reference electrode. A CRP limit of detection (LOD of 2.2 ng·mL−1 was achieved in spiked serum samples, and performance agreement was obtained with reference to a commercial ELISA kit. The developed CRP immunosensor was able to detect a diagnostically relevant range of the biomarker in serum without the need for signal amplification using nanoparticles, paving the way for future development on a cardiac panel electrochemical point-of-care diagnostic device.

    In this study, we propose a novel biosensor based on a gated lateral bipolar junction transistor (BJT) for biomaterial detection. The gated lateral BJT can function as both a BJT and a metal-oxide-semiconductor field-effect transistor (MOSFET) with both the emitter and source, and the collector and drain, coupled. C-reactive protein (CRP), which is an important disease marker in clinical examinations, can be detected using the proposed device. In the MOSFET-BJT hybrid mode, the sensitivity, selectivity, and reproducibility of the gated lateral BJT for biosensors were evaluated in this study. According to the results, in the MOSFET-BJT hybrid mode, the gated lateral BJT shows good selectivity and reproducibility. Changes in the emitter (source) current of the device for CRP antigen detection were approximately 0.65, 0.72, and 0.80 μA/decade at base currents of -50, -30, and -10 μA, respectively. The proposed device has significant application in the detection of certain biomaterials that require a dilution process using a common biosensor, such as a MOSFET-based biosensor. PMID:21835604

    C-reactive protein (CRP) is the most acute-phase reactant serum protein of inflammation and a strong predictor of cardiovascular disease. Its expression is associated with atherosclerotic plaque instability and the formation of immature micro-vessels. We have previously shown that CRP upregulates endothelial-derived Notch-3, a key receptor involved in vascular development, remodelling and maturation. In this study, we investigated the links between the bioactive monomeric CRP (mCRP) and Notch-3 signalling in angiogenesis. We used in vitro (cell counting, wound-healing and tubulogenesis assays) and in vivo (chorioallantoic membrane) angiogenic assays and Western blotting to study the angiogenic signalling pathways induced by mCRP and Notch-3 activator chimera protein (Notch-3/Fc). Our results showed an additive effect on angiogenesis of mCRP stimulatory effect combined with Notch-3/Fc promoting bovine aortic endothelial cell (BAEC) proliferation, migration, tube formation in Matrigel(TM) with up-regulation of phospho-Akt expression. The pharmacological blockade of PI3K/Akt survival pathway by LY294002 fully inhibited in vitro and in vivo angiogenesis induced by mCRP/Notch-3/Fc combination while blocking Notch signalling by gamma-secretase inhibitor (DAPT) partially inhibited mCRP/Notch-3/Fc-induced angiogenesis. Using a BAEC vascular smooth muscle cell co-culture sprouting angiogenesis assay and transmission electron microscopy, we showed that activation of both mCRP and Notch-3 signalling induced the formation of thicker sprouts which were shown later by Western blotting to be associated with an up-regulation of N-cadherin expression and a down-regulation of VE-cadherin expression. Thus, mCRP combined with Notch-3 activator promote angiogenesis through the PI3K/Akt pathway and their therapeutic combination has potential to promote and stabilize vessel formation whilst reducing the risk of haemorrhage from unstable plaques.

    Background C-reactive protein (CRP) has been reported to damage the vascular wall by inducing endothelial dysfunction and inflammation,and it is also speculated to have a role in attenuating angiogenic functions of human endothelial progenitor cells (EPCs).Interleukin-8 (IL-8) is an important mediator of the paracrine mitogenic effect of EPCs,which has direct angiogenic effects on mature endothelial cells.We,herein,investigated the direct effect of CRP on IL-8 production and gene expression in cultured human EPCs.Methods EPCs were isolated from the peripheral venous blood of healthy male volunteers.Cells were cultured in EndoCultTM liquid medium in the absence and presence of CRP at clinically relevant concentrations (5 to 25 μg/ml) for different durations (3 to 48 hours).IL-8 protein and mRNA of cultured EPCs were evaluated using ELISA and real-time PCR.Results The results showed that CRP at a concentration of 10 pg/ml significantly reduced IL-8 secretion of cultured EPCs with a peak at 25 μg/ml,and also decreased mRNA expression in EPCs with a peak at 12 hours.In addition,preincubation of EPCs with SB203580,an inhibitor of p38 mitogen-activated protein kinase (MAPK) decreased CRP inhibition of IL-8 mRNA expression at 12 hours in EPCs.Conclusions Our study,for the first time,demonstrates that CRP directly inhibits EPCs IL-8 secretion,a key cytokine player of angiogenesis induced by EPCs.Inhibition occurred in part via an effect of CRP to active the p38 MAPK signal transduction pathway in EPC.The ability of CRP to inhibit EPCs IL-8 secretion may represent an important mechanism that further links inflammation to cardiovascular disease.

    In this study, we report a novel aptamer-based capacitive label-free biosensor for monitoring transducing aptamer-protein recognition events, based on charge distribution under the applied frequency by non-Faradaic impedance spectroscopy (NFIS). This approach to capacitive biosensors is reported for the first time in this study, is reagent-less in processing and is developed using gold interdigitated (GID) capacitor arrays functionalized with synthetic RNA aptamers. The RNA atpamers served as biorecognition elements for C-reactive protein (CRP), a biomarker for cardiovascular disease risk (CVR). The signal is generated as a result of the change in relative capacitance occurring as a result of the formation of an RNA-CRP complex on GID capacitors with the applied AC electrical frequency (50-350 MHz). The dispersion peak of the capacitance curve was dependent on the CRP concentration and tends to shift toward lower frequencies, accompanied by the increase in relaxation time due to the increased size of the aptamer-CRP complex. The dissociation constant (K(d)) calculated from the non-linear regression analysis of the relative capacitance change with the applied frequency showed that strong binding of CRP occurred at 208 MHz (K(d) = 1.6 microM) followed by 150 MHz (K(d) = 4.2 microM) and 306 MHz (K(d) = 3.4 microM) frequencies. The dynamic detection range for CRP is determined to be within 100-500 pg ml(-1). Our results demonstrates the behavior of an RNA-protein complex on GID capacitors under an applied electric field, which can be extended to other pairs of affinity biomolecules as well as for the development of electrical biosensor systems for different applications, including the early diagnosis of diseases.
