    Patients with nursing home acquired pneumonia (NHAP) present a distinct group of lower respiratory track infections with different risk factors, clinical presentation, and mortality rates. To evaluate the diagnostic value of clinical pulmonary infection score (CPIS), C-reactive protein, and procalcitonin and to compare the accuracy of pneumonia severity scores (confusion, urea nitrogen, breathing frequency, blood pressure, ≥ 65 y of age [CURB-65]; pneumonia severity index; NHAP index; systolic blood pressure, multilobar involvement, albumin, breathing frequency, tachycardia, confusion, oxygen, arterial pH [SMART-COP]; and systolic blood pressure, oxygen, age > 65 y, breathing frequency [SOAR]) in predicting in-patient mortality from NHAP. Nursing home residents admitted to the hospital with acute respiratory illness were enrolled in the study. Subjects were classified as having NHAP (Group A) or other pulmonary disorders (Group B). Clinical, imaging, and laboratory data were assessed to compute CPIS and severity scores. C-reactive protein and procalcitonin were measured by immunonephelometry and immunoassay, respectively. Fifty-eight subjects were diagnosed with NHAP (Group A) and 29 with other pulmonary disorders (Group B). The mean C-reactive protein ± SD was 16.38 ± 8.6 mg/dL in Group A and 5.2 ± 5.6 mg/dL in Group B (P 1.1 ng/mL was an independent predictor of in-patient mortality. Of the pneumonia severity scores, CURB-65 showed greater accuracy in predicting in-patient mortality (area under the curve of 0.68, 95% CI 0.53-0.84, P = .06). CPIS, procalcitonin, and C-reactive protein are reliable for the diagnosis of NHAP. Procalcitonin and CURB-65 are accurate in predicting in-patient mortality in NHAP.

    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 Aim: This study was intended to assess the clinical usefulness of blood procalcitonin (PCT concentrations for the diagnosis and therapeutic monitoring of nosocomial neonatal sepsis.Material/Methods: The enrolment criterion was sepsis clinically manifesting after three days of life. PCT concentrations were measured in venous blood from 52 infected and 88 uninfected neonates. The results were interpreted against C-reactive protein (CRP concentrations and white blood cell counts (WBC.Results: Differences between the two groups in PCT and CRP concentrations were highly significant. No significant differences between the groups were noted for WBC. The threshold value on the receiver operator characteristic curve was 2.06 ng/mL for PCT (SE 75%; SP 80.68%; PPV 62.22%; NPV 88.75%; AUC 0.805, 5.0 mg/L for CRP (SE 67.44%; SP 73.68%; PPV 42.02%; NPV 88.89%; AUC 0.801, and 11.9 x109/L for WBC (SE 51.16%; SP 50.68%; PPV 23.16%; NPV 78.13%; AUC 0.484. Procalcitonin concentrations decreased 24 hours after initiation of antibiotic therapy and reverted to the control level after 5-7 days. C-reactive protein concentrations began to decline after two days of antibiotic therapy but were still higher than in the control group after 5-7 days of treatment. No significant changes in WBC during the treatment were observed.Conclusions: Procalcitonin concentrations in blood appear to be of use for the diagnosis and therapeutic monitoring of nosocomial infections in neonates as this parameter demonstrates greater sensitivity and specificity than C-reactive protein. White blood cell counts appear to be of little diagnostic value in the early phase of infection or for therapeutic monitoring.

    Urinary infections are a common type of pediatric disease, and their treatment and prognosis are closely correlated with infection location. Common clinical manifestations and laboratory tests are insufficient to differentiate between acute pyelonephritis and lower urinary tract infection. This study was conducted to explore a diagnostic method for upper and lower urinary tract infection differentiation. The diagnostic values of procalcitonin (PCT) and C-reactive protein (CRP) were analyzed using the receiver operating characteristic curve method for upper and lower urinary tract infection differentiation. PCT was determined using chemiluminescent immunoassay. The PCT and CRP values in children with acute pyelonephritis were significantly higher than those in children with lower urinary tract infection (3.90 ± 3.51 ng/ml and 68.17 ± 39.42 mg/l vs. 0.48 ± 0.39 ng/ml and 21.39 ± 14.92 mg/l). The PCT values were correlated with the degree of renal involvement, whereas the CRP values failed to show such a significant correlation. PCT had a sensitivity of 90.47% and a specificity of 88% in predicting nephropathia, whereas CRP had sensitivity of 85.71% and a specificity of 48%. Both PCT and CRP can be used for upper and lower urinary tract infection differentiation, but PCT has higher sensitivity and specificity in predicting pyelonephritis than CRP. PCT showed better results than CRP. PCT values were also correlated with the degree of renal involvement.

    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.

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

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

    Anastomotic leakage is the most important complication after colorectal surgery. Its prognosis depends on its early diagnosis. C-reactive protein (CRP) has already shown its usefulness for the early detection of anastomotic leaks. Procalcitonin (PCT) is widely used in intensive care units and is more expensive, but its usefulness in the postoperative period of digestive surgery is not well established. Between May 2010 and June 2011, 100 patients undergoing elective colorectal surgery were prospectively included in a database. CRP and PCT were measured before surgery and daily until postoperative day 4. All intraabdominal infections were considered as anastomotic leaks, regardless of their clinical impact and their management. The kinetics of PCT and CRP were recorded, as well as their accuracy for the detection of anastomotic fistula. The incidence of fistula was 13% and the overall mortality rate was 2%. Both CRP and PCT were significantly higher in patients with leakage. Areas under the receiver-operating characteristics (ROC) for CRP were higher than those for PCT each day. The best accuracy was obtained for CRP on postoperative day 4 (areas under the ROC curve were 0.869 for CRP and 0.750 for PCT). Procalcitonin is neither earlier nor more accurate than CRP for the detection of anastomotic leakage after elective colorectal surgery. Copyright © 2012 Elsevier Masson SAS. All rights reserved.

    The aim of this study was to evaluate procalcitonin (PCT), C-reactive protein (CRP), platelet count (PLT) and serum lactate dehydrogenase (LDH) as early markers for diagnosis of SIRS, bacterial sepsis and systemic candidiasis in intensive care unit (ICU) patients. Based on blood culture results, the patients were divided into a sepsis group (70 patients), a SIRS group (42 patients) and a systemic candidiasis group (33 patients). PCT, CRP, LDH and PLT levels were measured on day 0 and on day 2 from the sepsis symptom onset. PCT levels were higher in Gram negative sepsis than those in Gram positive sepsis, although the P value between the two subgroups is not significant (P=0.095). Bacterial sepsis group had higher PCT and CRP levels compared with the systemic candidiasis group, whereas PLT and LDH levels showed similar levels in these two subgroups. The AUC for PCT (AUC: 0.892, P candidiasis groups (P=0.093 N.S.). In conclusion, PCT can be used as a preliminary marker in the event of clinical suspicion of systemic candidiasis; however, low PCT levels (candidiasis and SIRS groups.

    The performance of most bariatric procedures within an Enhanced Recovery After Surgery (ERAS) programs has resulted in considerable advantages, including a reduction in the length of hospital stay to 2 to 3 days. However, some postoperative complications can appear after the patient has been discharged. The aim of this study was to investigate the efficacy of various acute-phase parameters determined 24 and 48 hours after laparoscopic sleeve gastrectomy (LSG) as bariatric procedure, for predicting septic complications, such a surgical site infection (SSI), in the postoperative course. A prospective study of 115 morbidly obese patients who underwent LSG within an ERAS program between 2012 and 2015 was conducted. Blood analysis was performed 24 and 48 hours after surgery. Acute-phase parameters (C-reactive protein [CRP], procalcitonin, and fibrinogen) and WBC count were investigated. Septic complications were observed in 13 patients (11.3%). Using receiver operating characteristic analysis at 24 hours postoperatively, a cutoff level of CRP at 70 mg/L achieved 85% sensitivity and 90% specificity for predicting SSI, and a cutoff level of procalcitonin at 0.2 ng/mL achieved 70% sensitivity and 90% specificity. At 48 hours postoperatively, a cutoff level of CRP at 150 mg/L and procalcitonin at 0.95 ng/mL achieved 100% sensitivity and 100% specificity for predicting SSI. The use of CRP and procalcitonin in the first day and especially in the second day postoperative can predict septic complications after LSG. This is most useful for patients within an ERAS program who will be discharged early. Copyright © 2016 American College of Surgeons. Published by Elsevier Inc. All rights reserved.

    The aim of this study was to analyze and compare the capacity of procalcitonin (PCT), C-reactive protein (CRP), lactate and leukocytes to predict the presence of bacteremia in patients with urinary tract infections (UTIs). Observational, retro-prospective analytical study of adult patients (≥15 years) diagnosed with UTI in an emergency department from August 2012 to January 2013. The study included 328 patients diagnosed with UTI, with a mean age of 52±22 years, 74% of whom were women. Of these, 43 (13.1%) had bacteremia. For predicting bacteremia, PCT achieved the largest area under the receiver operating characteristic curve (ROC-AUC) at .993 (95% CI .987-1; P<.001). A cutoff≥1.16ng/mL achieves a sensitivity of 100%, a specificity of 97%, a positive predictive value of 84% and a negative predictive value of 100%. Lactate achieved an ROC-AUC of .844, and CRP achieved only .534. The mean values when comparing PCT levels in patients with UTIs with and without bacteremia were 8.08±16.37 and .34±.37ng/mL, respectively (P<.001). For patients with UTIs in the emergency department, PCT achieves considerable diagnostic performance for suspecting bacteremia, a performance greater than that of lactate, CRP and leukocytes.

    The performance of most bariatric procedures within an Enhanced Recovery After Surgery program has resulted in significant advantages, including a reduction in the length of hospital stay to 2-3 days. However, some postoperative complications may appear after the patient has been discharged. The aim of this study was to investigate the efficacy of various acute-phase parameters determined 24 h after a laparoscopic sleeve gastrectomy for predicting staple line leak in the postoperative course. A prospective study of 208 morbidly obese patients undergoing laparoscopic sleeve gastrectomy as bariatric procedure between 2012 and 2015 was performed. Blood analysis was performed 24 h after surgery. Acute-phase parameters (C-reactive protein, procalcitonin, fibrinogen, and White Blood Cell count) were investigated. Staple line leak appeared in eight patients (3.8%). Using receiver operating characteristic analysis at 24 h postoperatively, a cutoff level of CRP at 9 mg/dL achieved 85% sensitivity and 90% specificity for predicting staple line leak, a cutoff level of procalcitonin at 0.85 ng/mL achieved 70% sensitivity and 90% specificity, and a cutoff level of fibrinogen at 600 mg/dL achieved 80% sensitivity and 87.5% specificity. An elevation of CRP > 9 mg/dL, procalcitonin > 0.85 ng/mL and fibrinogen > 600 mg/dL should alert the surgeon the possibility of occurrence of postoperative staple line leak.

    Objective(s) In the last few years, serum procalcitonin has been proposed as an early marker of infections in neonates, with varying results. In this study, we aimed to investigate the value of procalcitonin, and C- reactive protein in establishing the diagnosis of neonatal sepsis. Materials and Methods Blood samples were collected at admission from 69 neonates with suspected infection (admitted to the Neonatal Intensive Care Units at Alzahra and Dr Beheshti Hospital in and Fatema-Zahra in Najafabad from May 2005 to April 2006). Patients were categorized in different groups according to clinical symptoms of sepsis, bacteriological and laboratory results. Group I consisted of 20 newborns with positive blood cultures and other biological tests which suggested infection. Group II consisted of 49 neonates with negative blood cultures but had two or three of clinical signs of sepsis. The control group included 18 healthy neonates with physiological hyperbilirubinemia and no clinical and biological data of infection, referred to the hospital for bilirubin determination. Procalcitonin and C-reactive protein (CRP) were determined by immunoluminometric assay and nephlometry method respectively. Results Mean levels of procalcitonin and CRP in septic neonates (group I) were significantly higher than the other two groups (P< 0.005). Sensitivity, specificity, positive predictive value and negative predictive value were determined for all markers and compared with each other. Conclusion We conclude that procalcitonin is a better marker than CRP in the diagnosis of neonatal sepsis. PMID:23493845

    Full Text Available Despite vaccines and improved medical intensive care, clinicians must continue to be vigilant of possible Meningococcal Disease in children. The objective was to establish if the procalcitonin test was a cost-effective adjunct for prodromal Meningococcal Disease in children presenting at emergency department with fever without source.Data to evaluate procalcitonin, C-reactive protein and white cell count tests as indicators of Meningococcal Disease were collected from six independent studies identified through a systematic literature search, applying PRISMA guidelines. The data included 881 children with fever without source in developed countries.The optimal cut-off value for the procalcitonin, C-reactive protein and white cell count tests, each as an indicator of Meningococcal Disease, was determined. Summary Receiver Operator Curve analysis determined the overall diagnostic performance of each test with 95% confidence intervals. A decision analytic model was designed to reflect realistic clinical pathways for a child presenting with fever without source by comparing two diagnostic strategies: standard testing using combined C-reactive protein and white cell count tests compared to standard testing plus procalcitonin test. The costs of each of the four diagnosis groups (true positive, false negative, true negative and false positive were assessed from a National Health Service payer perspective. The procalcitonin test was more accurate (sensitivity=0.89, 95%CI=0.76-0.96; specificity=0.74, 95%CI=0.4-0.92 for early Meningococcal Disease compared to standard testing alone (sensitivity=0.47, 95%CI=0.32-0.62; specificity=0.8, 95% CI=0.64-0.9. Decision analytic model outcomes indicated that the incremental cost effectiveness ratio for the base case was £-8,137.25 (US $ -13,371.94 per correctly treated patient.Procalcitonin plus standard recommended tests, improved the discriminatory ability for fatal Meningococcal Disease and was more cost

    To determine whether procalcitonin is a reliable diagnostic and prognostic marker in septic shock compared with nonseptic shock. Prospective controlled trial. Intensive care unit of the Avicenne Teaching Hospital, Bobigny, France. All patients admitted to our intensive care unit over a 12-month period with clinical evidence of shock. None. Echocardiography or pulmonary artery flotation catheter measurements were used to assess hemodynamics, and multiple specimens were obtained for microbiological studies. Standard criteria were used to diagnose septic shock. Serum concentrations of procalcitonin, C-reactive protein, and lactate were determined on the day of shock onset (day 1) and on days 3, 7, and 10. Seventy-five patients were included, 62 in the septic shock group and 13 in the cardiogenic shock group. Serum procalcitonin on day 1 was significantly higher in patients with than without septic shock (median, 14 [0.3-767] ng/mL vs. 1 [0.5-36] ng/mL, p < .01). A cutoff value of 1 ng/mL had 95% sensitivity and 54% specificity for separating patients with and without sepsis. C-reactive protein failed to discriminate between these two groups. Among patients with sepsis, procalcitonin concentrations were significantly higher in those who died than in the survivors, at all four measurement time points (median, 16 [0.15-767] ng/mL vs. 6 [0.2-123] ng/mL, p = .045 on day 1; 6.5 [0.3-135] ng/mL vs. 1.05 [0.11-53] ng/mL, p = .02 on day 10). A cutoff value of 6 ng/mL on day 1 separated patients who died from those who survived with 87.5% sensitivity and 45% specificity. C-reactive protein was not helpful for predicting mortality. Serum lactate was a nonspecific prognostic marker. These data indicate that procalcitonin may be a valuable early diagnostic and prognostic marker in patients with septic shock.

    Previous studies have focused on relationship between plasma procalcitonin level and myocardial infarction risk, but this relationship in Asian elderly has not been investigated. The aim of this study was to reveal the association of peripheral procalcitonin concentration (both immediate and average levels) with myocardial infarction prognosis in Asian elderly. A total of 400 ST-elevation myocardial infarction patients, 400 unstable angina patients and 400 controls were included. Plasma levels of high-sensitivity C-reactive protein and procalcitonin were measured using commercially available kits. Each myocardial infarction patient received a standard therapy and a 12-month follow-up unless major adverse cardiac events occurred. On admission, plasma procalcitonin level was higher in myocardial infarction patients than in unstable angina patients and controls (p < .001). In the follow-up period, 142 myocardial infarction patients suffered from major adverse cardiac events, and other 258 myocardial infarction patients did not. Higher admission, peak and average plasma levels of procalcitonin in the first week after chest pain onset were associated with elevated risk of major adverse cardiac events (HR: 1.46, 95%CI: 1.18-1.99; HR: 2.57, 95%CI: 1.99-3.52; HR: 2.36, 95%CI: 1.81-3.00). Plasma procalcitonin level had a positive linear correlation with plasma level of high-sensitivity C-reactive protein on admission (r = 0.650, p < .001). In conclusion, peripheral concentration of procalcitonin (both immediate and average levels) might be an independent predictor for prognosis in myocardial infarction patients. Prognostic significance of procalcitonin might be implicated in inflammation.

    Among the most common early complications after bariatric surgery are anastomosis leak and bleeding. In order to react quickly and perform accurate treatment before the clinical signs appear, early predictors should be found. In the study C-reactive protein (CRP) and procalcitonin (PCT) levels were investigated. Characterized by a relatively short half-life, they can predict surgical complications. To develop and implement certain standards for early detection of complications. The study involved 319 adults who underwent laparoscopic sleeve gastrectomy (LSG) as a surgical intervention for morbid obesity at the Department of General Surgery of Ceynowa Hospital in Wejherowo. Every patient had CRP and PCT levels measured before the surgery and on the 1 st and 2 nd postoperative day (POD). Early postoperative complications occurred in 19 (5.96%) patients. Septic and non-septic complications occurred in 3 and 16 patients respectively. Among the patients with septic postoperative complications CRP level increased significantly on the 2 nd POD compared to the remainder (p = 0.0221). Among the patients with non-septic postoperative complications CRP level increased significantly on the 1 st and 2 nd POD compared to the remainder. Among the patients with septic and non-septic postoperative complications PCT level increased significantly on the 2 nd POD compared to the remainder. The CRP and PCT level are supposed to be relevant diagnostic markers to predict non-septic and septic complications after LSG.

    There is a lack of studies comparing the utility of C-reactive protein (CRP) with Procalcitonin (PCT) for the management of patients with acute respiratory tract infections (ARI) in primary care. Our aim was to study the correlation between these markers and to compare their predictive accuracy in regard to clinical outcome prediction. This is a secondary analysis using clinical and biomarker data of 458 primary care patients with pneumonic and non-pneumonic ARI. We used correlation statistics (spearman's rank test) and multivariable regression models to assess association of markers with adverse outcome, namely days with restricted activities and persistence of discomfort from infection at day 14. At baseline, CRP and PCT did not correlate well in the overall population (r(2) = 0.16) and particularly in the subgroup of patients with non-pneumonic ARI (r(2) = 0.08). Low correlation of biomarkers were also found when comparing cut-off ranges, day seven levels or changes from baseline to day seven. High baseline levels of CRP (>100 mg/dL, regression coefficient 1.6, 95 % CI 0.5 to 2.6, sociodemographic-adjusted model) as well as PCT (>0.5ug/L regression coefficient 2.0, 95 % CI 0.0 to 4.0, sociodemographic-adjusted model) were significantly associated with larger number of days with restricted activities. There were no associations of either biomarker with persistence of discomfort at day 14. CRP and PCT levels do not well correlate, but both have moderate prognostic accuracy in primary care patients with ARI to predict clinical outcomes. The low correlation between the two biomarkers calls for interventional research comparing these markers head to head in regard to their ability to guide antibiotic decisions.

SOFA and APACHE II scores as well as serum biomarkers were measured at days 0, 2 and 5. The influence of these variables on 28-day mortality was analyzed. Twenty healthy individuals served as controls.Baseline serum concentrations of sTREM-1, sCD163, IL-6 and PCT correlated with SOFA score. Only sTREM-1 levels correlated with APACHE II score. The 28-day mortality rate for all patients was 42%. The absence of risk factors for infection, presence of septic shock, baseline values of sCD14 and decrease of PCT and IL-6 from baseline to day 5 were variables associated to mortality in the univariate analysis. The unique independent factor associated to mortality in the multivariate analysis was a decrease of PCT higher than 50% from days 0 to 5.Serum levels of sTREM-1 are correlated with the severity of sepsis. A 50% decrease of PCT was the unique variable associated with survival in the multivariate analysis.

    Although the role of serum procalcitonin (PCT) and high-sensitivity C-reactive protein (hs-CRP) in the diagnosis of sepsis and septic shock is well studied, it has not been investigated among oldest old patients. The aim of our study is to determine the role of PCT and hs-CRP in the assessment of sepsis and septic shock in this specific group of patients in the ICU. This is a prospective observational study. Patients >85 years of age admitted to the ICU from May 1st, 2016 to February 1st, 2017 were evaluated. Patients were divided into a sepsis and septic shock group(sepsis/SS) and a non-sepsis group. Serum levels of PCT, hs-CRP and the WBC were measured within 12 h of admission. A total of 70 patients aged 85 years and older were enrolled in this study. Fifty patients were labelled as sepsis/SS and the other 20 were labelled non-sepsis. A ROC analysis showed that the area under the curves (AUC) of hs-CRP and PCT for the discrimination of sepsis/SS patients were 0.825 (95% confidence interval[CI]: 0.73-0.92; P sepsis/SS group, 27 patients had sepsis, while the other 23 patients had septic shock. The ROC analysis showed that the AUCs of hs-CRP and PCT for the discrimination of septic shock patients from sepsis patients were 0.751 (95% CI: 0.62-0.88; P = 0.002) and 0.719 (95% CI:0.57-0.86; p = 0.007), respectively. For the oldest old patients, hs-CRP is not inferior to PCT in the diagnosis of sepsis and septic shock.

    C-reactive protein (CRP) and procalcitonin (PCT) have been described as good predictors of anastomotic leak after colorectal surgery, obtaining the highest diagnostic accuracy on the 5th postoperative day. However, if an enhanced recovery after surgery (ERAS) program is performed, early predictors are needed in order to ensure a safe and early discharge. The aim of this study was to investigate the efficacy of CRP, PCT, and white blood cell (WBC) count determined on first postoperative days, in predicting septic complications, especially anastomotic leak, after laparoscopic colorectal surgery performed within an ERAS program. We conducted a prospective study including 134 patients who underwent laparoscopic colorectal surgery within an ERAS program between 2015 and 2017. The primary endpoint investigated was anastomotic leak. CRP, PCT, and WBC count were determined in the blood sample extracted on postoperative day 1 (POD 1), POD 2 and POD 3. Anastomotic leak (AL) was detected in 6 patients (4.5%). Serum levels of CRP and PCT, but not WBC, determined on POD 1, POD 2, and POD 3 were significantly higher in patients who had AL in the postoperative course. Using ROC analysis, the best AUC of the CRP and PCT levels was on POD 3 (0.837 and 0.947, respectively). A CRP cutoff level at 163 mg/l yielded 85% sensitivity, 80% specificity, and 99% negative predictive value (NPV). A PCT cutoff level at 2.5 ng/ml achieved 85% sensitivity, 95% specificity, 44% positive predictive value, and 99% NPV. CRP and PCT are relevant markers for detecting postoperative AL after laparoscopic colorectal surgery. Furthermore, they can ensure an early discharge with a low probability of AL when an ERAS program is performed.

    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)

    Diabetic foot is a common complication of diabetes due to changes in blood vessels and nerves, often leads to ulceration and subsequent limb amputation if not treated early. A new diagnostic marker of bacterial infections is procalcitonin. C-reactive protein, Interleukin1β, Interleukin-6 and tumor necrosis factor-α as proinflammatory parameters increased in Diabetic foot infection. We evaluated above parameters in patients with diabetic foot infections in different grades. A total of 130 diabetic patients were enrolled in this case control study between June 2011 and March 2012 in Rizgary, Emergency and Hawler Teaching Hospitals, 90 of them with diabetic foot lesion as a patient group. 40 without foot lesion, as a patient control and 20 individuals as healthy control. Assessment of above parameters in sera of study groups and also bacteriological tests (bacterial isolation and identification) were done. Serum procalcitonin levels significantly increased in patients with diabetic foot with higher Wagner grades (III, IV and V) (0.28 ± 0.04, 0.30 ± 0.07 and 0.60 ± 0.11) respectively (Pfoot ulcer based on Wagner classification system was also associated with circulating levels of C-reactive protein, Interleukin1β, Interleukin-6 and tumor necrosis factor-α (G III, IV and V) (5.36 ± 0.70, 6.38 ± 0.65, and 9.13 ± 0.88), (1.21 ± 0.08, 1.56 ± 0.16 and 2.02 ± 0.07), (23.02 ± 2.98, 36.32 ± 5.75 and 43.36 ± 6.16), and (215.39 ± 16.8, 259.21 ± 40.7 and 398.45 ± 33.4) respectively (Pdiabetic foot patients may be a procalcitonin especially in those with higher Wagner grades and with polymicrobial infection.

    Fiona J McCann

    Full Text Available Procalcitonin has been shown to be useful in separating infection from non-infective disorders. However, infection is often paralleled by tissue inflammation. Most studies supporting the use of procalcitonin were confounded by more significant inflammation in the infection group. Few studies have examined the usefulness of procalcitonin when adjusted for inflammation.Pleural inflammation underlies the development of most exudative effusions including pleural infection and malignancy. Pleurodesis, often used to treat effusions, involves provocation of intense aseptic pleural inflammation. We conducted a two-part proof-of-concept study to test the specificity of procalcitonin in differentiating infection using cohorts of patients with pleural effusions of infective and non-infective etiologies, as well as subjects undergoing pleurodesis.We measured the blood procalcitonin level (i in 248 patients with pleural infection or with non-infective pleural inflammation, matched for severity of systemic inflammation by C-reactive protein (CRP, age and gender; and (ii in patients before and 24-48 hours after induction of non-infective pleural inflammation (from talc pleurodesis.1 Procalcitonin was significantly higher in patients with pleural infection compared with controls with non-infective effusions (n = 32 each group that were case-matched for systemic inflammation as measured by CRP [median (25-75%IQR: 0.58 (0.35-1.50 vs 0.34 (0.31-0.42 µg/L respectively, p = 0.003]. 2 Talc pleurodesis provoked intense systemic inflammation, and raised serum CRP by 360% over baseline. However procalcitonin remained relatively unaffected (21% rise. 3 Procalcitonin and CRP levels did not correlate. In 214 patients with pleural infection, procalcitonin levels did not predict the survival or need for surgical intervention.Using a pleural model, this proof-of-principle study confirmed that procalcitonin is a biomarker specific for infection and is not affected by non

    Cryptogenic Organising Pneumonia (COP) is a relatively rare condition and can be difficult to differentiate from Community acquired pneumonia (CAP). We report two cases which demonstrate the importance of considering this differential diagnosis in patients with spontaneous pneumothorax who have raised inflammatory markers or lung infiltrates. Our report highlights the value of serum procalcitonin as a biomarker in differentiating between community acquired pneumonia and cryptogenic organising pneumonia especially in the context of a high serum C-reactive protein. Furthermore, the cases show early diagnosis and prompt treatment with corticosteroids may impact the clinical outcome.

    To investigate whether low-grade inflammation-related factors such as serum low-density (LDL-C) and high-density lipoprotein cholesterol (HDL-C) modify the association between periodontal infection and C-reactive protein. This study was based on a subpopulation of the Health 2000 Survey, which consisted of dentate, non-diabetic, non-rheumatic subjects who were 30-49 years old (n = 2710). The extent of periodontal infection was measured by means of the number of teeth with periodontal pocket ≥4 mm and teeth with periodontal pocket ≥6 mm and systemic inflammation using high sensitive C-reactive protein. The extent of periodontal infection was associated with elevated levels of C-reactive protein among those subjects whose HDL-C value was below the median value of 1.3 mmol/l or LDL-C above the median value of 3.4 mmol/l. Among those with HDL-C ≥ 1.3 mmol/l or LDL-C ≤ 3.4 mmol/l, the association between periodontal infection and serum concentrations of C-reactive protein was practically non-existent. This study suggests that the relation of periodontal infection to the systemic inflammatory condition is more complicated than previously presumed. The findings of this study suggest that the possible systemic effect of periodontal infection is dependent on serum lipid composition. © 2012 John Wiley & Sons A/S.

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

    Frédéric Sapin

    Full Text Available OBJECTIVES: The development of sepsis after abdominal surgery is associated with high morbidity and mortality. Due to inflammation, it may be difficult to diagnose infection when it occurs, but measurement of C-reactive protein could facilitate this diagnosis. In the present study, we evaluated the predictive value and time course of C-reactive protein in relation to outcome in patients admitted to the intensive care unit (ICU after abdominal surgery. METHODS: We included patients admitted to the ICU after abdominal surgery over a period of two years. The patients were divided into two groups according to their outcome: favorable (F; left the ICU alive, without modification of the antibiotic regimen and unfavorable (D; death in the ICU, surgical revision with or without modification of the antibiotic regimen or just modification of the regimen. We then compared the highest C-reactive protein level on the first day of admission between the two groups. RESULTS: A total of 308 patients were included: 86 patients had an unfavorable outcome (group D and 222 had a favorable outcome (group F. The groups were similar in terms of leukocytosis, neutrophilia, and platelet count. C-reactive protein was significantly higher at admission in group D and was the best predictor of an unfavorable outcome, with a sensitivity of 74% and a specificity of 72% for a threshold of 41 mg/L. No changes in C-reactive protein, as assessed based on the delta C-reactive protein, especially at days 4 and 5, were associated with a poor prognosis. CONCLUSIONS: A C-reactive protein cut-off of 41 mg/L during the first day of ICU admission after abdominal surgery was a predictor of an adverse outcome. However, no changes in the C-reactive protein concentration, especially by day 4 or 5, could identify patients at risk of death.

    Objective: To evaluate the efficacy of serum and CSF C-reactive protein (C-rp) in differentiating bacterial from viral meningitis. Design: An observational, respective hospital-based study. Place and duration of study: It was conducted at the Department of Medicine and Department of Pediatrics, Shaikh Zayed Postgraduate Medical Institute Lahore, Over a Period of one year between march, 1999 and March, 2000. Subject and Methods: A randomized group of thirty patients, who presented with clinical features, suggestive of meningitis, were included in the study. C-reactive protein determinations were performed by latex agglutination method on the serum and cerebrospinal fluid (CSF) of these patients. Results: In the present study, c-reactive protein was found to be a more sensitive test for differentiating bacterial from non-bacterial meningitis on initial examination than the usual conventional methods used to diagnose bacterial meningitis. CSF C-reactive protein had a greater sensitivity (92% as compared to serum C-reactive protein (71%). Conclusion: C-reactive protein determination in CSF was found to be a useful indicator of bacterial meningitis that can be used to distinguish it from viral meningitis. (author)

    high concentrations of maternal C-reactive protein have been associated with adverse pregnancy outcome, and premature uterine contraction may be predicted by elevated levels of C-reactive protein. This may ultimately be simple and cost-effective enough to introduce as a low-risk screening program. an observational case control study was performed from May 1st, 2010 to December 1st, 2010 at Maternity Teaching Hospital-Erbil/ Kurdistan Region/ Iraq. The sample size was (200) cases. Hundred of them were presented with premature uterine contractions at 24(+0)-36(+6) weeks. The other hundred were control group at same gestational ages. The level of C-reactive protein was determined in both groups and both groups were followed till delivery. (93) out of (100) women with premature uterine contractions had elevated level of C-Reactive protein and 91% delivered prematurely while in the control group only (9) out of (100) women had elevated level of C-reactive protein and only 8% of them delivered preterm. Differences were statistically highly significant. C-reactive protein can be used as a biomarker in prediction of premature delivery when it is associated with premature uterine contractions.

    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.

    To investigate the effect of C-reactive protein on the activated partial thromboplastin time (APTT) (different activators) in different detecting systems. The C-reactive protein and coagulation test of 112 patients with the infectious disease were determined by automation protein analyzer IMMAG 800 and automation coagulation analyzer STA-R Evolution, respectively. The pooled plasma APTT with different concentrations of C-reactive protein was measured by different detecting system: STA-R Evolution (activator: silica, kaolin), Sysmex CS-2000i (activator: ellagic acid), and ACL TOP 700 (activator: colloidal silica). In addition, the self-made platelet lysate (phospholipid) was added to correct the APTT prolonged by C-reactive protein (150 mg/L) on STA-R Evolution (activator: silica) system. The good correlation between C-reactive protein and APTT was found on the STA-R Evolution (activator: silica) system. The APTT on the STA-R Evolution (activator: silica) system was prolonged by 24.6 second, along with increasing C-reactive protein concentration. And the APTT of plasma containing 150 mg/L C-reactive protein was shortened by 3.4-6.9 second when the plasma was mixed with self-made platelet lysate. However, the APTT was prolonged unobviously on other detecting systems including STA-R Evolution (activator: kaolin), Sysmex CS-2000i, and ACL TOP 700. C-reactive protein interferes with the detection of APTT, especially in STA-R Evolution (activator: silica) system. The increasing in C-reactive protein results in a false prolongation of the APTT (activator: silica), and it is most likely that C-reactive protein interferes the coagulable factor binding of phospholipid. © 2018 Wiley Periodicals, Inc.

    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 appropriate management of aortic intramural hematoma is still controversial, because a variety of aortic events can arise during follow-up in some patients. However, simplified identification of these patients remains challenging. The present study aimed to determine the prognostic significance of serial C-reactive protein measurements for the prediction of adverse events in patients with acute aortic intramural hematoma. A total of 180 patients with aortic intramural hematoma were retrospectively reviewed. The C-reactive protein data were obtained at admission and 2 days, 1 week, and 2 weeks from the onset, and the maximum value was obtained during the acute phase. Adverse aorta-related events were defined by a composite of aortic rupture, aortic aneurysm, and surgical or endovascular aortic repair. The C-reactive protein value was 3.0 ± 4.6, 8.7 ± 5.9, 9.0 ± 5.5, and 5.7 ± 4.5 mg/dL on admission and 2 days, 1 week, and 2 weeks from the onset, respectively. The maximal value of C-reactive protein was 12.4 ± 6.3 mg/dL at a mean of 4 days from the onset. Patients with elevated C-reactive protein levels (≥7.2 mg/dL) at 2 weeks had significantly greater rates of aorta-related events (P analysis, an elevated C-reactive protein level at 2 weeks (hazard ratio, 3.16; P value compared with the development of an ulcer-like projection (chi-square, 16.94 for ulcer-like projection only vs 34.32 with the addition of C-reactive protein at 2 weeks, P < .001). C-reactive protein was a simple and useful marker providing incremental prognostic information compared with the development of an ulcer-like projection in patients with aortic intramural hematoma.

    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.

    Cardiovascular disease is the most common cause of morbidity and mortality globally. Epidemiological studies using high-sensitivity assays for serum C-reactive protein have shown a consistent association between cardiovascular disease risk and serum C-reactive protein concentrations. C-reactive protein is a biomarker for inflammation, and has been established in clinical practice as an independent risk factor for cardiovascular disease events. There is evidence that serum C-reactive protein is an excellent biomarker of cardiovascular disease and is also an independent and strong predictor of adverse cardiovascular events. Further characterization of the impact and influence of lifestyle exposures and genetic variation on the C-reactive protein response to cardiovascular disease events may have implications for the therapeutic approaches to reduce cardiovascular disease events. This review summarizes the studies that have examined the association between serum C-reactive protein and the risk of cardiovascular disease. We also discuss the impact of independent factors and C-reactive protein genetic polymorphisms on baseline plasma C-reactive protein levels. © 2018 Wiley Periodicals, Inc.

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

    2017-01-01

    Delayed or wrong diagnosis of acute appendicitis in patients results in complications like perforation, gangrene, etc. which carries a significant amount of morbidity and mortality to the patients. Thus, timely diagnosis of acute appendicitis is crucial to prevent these complications. Recently, it was found that serum C-reactive protein (CRP) individually can be a useful marker, thus in resource limited settings (i.e., access to ultrasonography) simple laboratory investigation can be of extreme utility for the diagnosis of acute appendicitis. Current study aimed to ascertain and determine the role of C Reactive Protein (CRP) as a complementary test to decrease the rate of negative appendectomies in tertiary care hospitals of Pakistan. Methods: Using non-probability consecutive sampling, 112 patients with the initial diagnosis of acute appendicitis on history and clinical examination were enrolled. A blood sample was taken for serum level of CRP. Results: Mean age was 20.8+-8.6 years and 51 (45.5 %) patients were males. Pathologic review revealed 100 cases (89.3%) of acute appendicitis, 4 patients (3.6%) had perforated appendix while 8 patients (7.1%) had normal appendix. Sensitivity, specificity, positive and negative predictive value and diagnostic accuracy of C reactive protein >24 mg/lit taking histology as gold standard came out 25.9%, 100%, 100%, 9.4% and 31.25% respectively. Conclusion: It was concluded that CRP >48 mg/lit is an indication of perforated appendix and when the surgeon is in fix whether to go conservatively or apply some intervention, CRP can be a good diagnostic aid.

    The objective of the present study was to investigate an association between early gestational C-reactive protein, an established inflammatory biomarker, prospectively assayed in maternal sera, and schizophrenia in a large, national birth cohort with an extensive serum biobank. A nested case-control design from the Finnish Prenatal Study of Schizophrenia cohort was utilized. A total of 777 schizophrenia cases (schizophrenia, N=630; schizoaffective disorder, N=147) with maternal sera available for C-reactive protein testing were identified and matched to 777 control subjects in the analysis. Maternal C-reactive protein levels were assessed using a latex immunoassay from archived maternal serum specimens. Increasing maternal C-reactive protein levels, classified as a continuous variable, were significantly associated with schizophrenia in offspring (adjusted odds ratio=1.31, 95% confidence interval=1.10-1.56). This finding remained significant after adjusting for potential confounders, including maternal and parental history of psychiatric disorders, twin/singleton birth, urbanicity, province of birth, and maternal socioeconomic status. This finding provides the most robust evidence to date that maternal inflammation may play a significant role in schizophrenia, with possible implications for identifying preventive strategies and pathogenic mechanisms in schizophrenia and other neurodevelopmental disorders.

    Full Text Available Background/purpose: The aim of this study was to evaluate and compare the systemic levels of C-reactive protein (CRP in peripheral blood samples of patients with aggressive periodontitis during the first twelve months of periodontal treatment, at exactly six month interval measurements, and compare them with clinical periodontal parameters. Materials and methods: All patients (N = 45 were examined prior to the initiation of periodontal treatment. Patients were divided into two groups GAgP (Generalised form of aggressive periodontitis, N = 23 and group LAgP (Localised form of aggressive periodontitis, N = 22. Control group (CON included 60 individuals with healthy periodontium. The levels of CRP were determined in both groups GAgP and LAgP three times in 6 month intervals during the periodontal treatment. Results: CRP is a plasma protein that reflects the extent of the acute phase response to inflammation and is one of the markers of choice for monitoring this response. In our study, CRP levels decreased in course of periodontal treatment in both groups (GAgP and LAgP in a similar way as bleeding on probing (BOP and probing pocket depth (PPD indices. Conclusion: Our study results showed that CRP levels, as well as bleeding on probing (BOP and probing pocket depth (PPD, indices decreased in course of periodontal treatment in patients with generalised and localised aggressive periodontitis. Therefore this marker might be exploitable as a means to evaluate periodontal health in patients with aggressive periodontitis.

Methods: The subjects were 37 febrile patients with urinary tract infection in whom we examined the serum procalcitonin concentration at the start of treatment. Results: Thirty patients had acute pyelonephritis (16 simple, 14 complex, one had emphysematous pyelonephritis, five had acute prostatitis, and one had acute epididymitis. The procalcitonin level was <0.5 ng/mL in 18 patients, ≥0.5 ng/mL in one patient, ≥2 ng/mL in seven patients, and ≥10 ng/mL in 11 patients. Five of the 11 patients with procalcitonin levels ≥ 10 ng/mL had disseminated intravascular coagulation. All patients with urinary tract obstruction and disseminated intravascular coagulation had procalcitonin levels ≥ 10 ng/mL. Conclusion: Although this retrospective study comprised a small number of patients, we found that procalcitonin was a useful marker for urinary tract infection.

    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.

    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

    Full Text Available OBJECTIVE: The objective of this trial was to determine the levels of inflammatory markers, high-sensitivity C-reactive protein and fetuin-A pre- and post-levothyroxine treatment in cases of subclinical hypothyroidism. MATERIALS AND METHODS: A total of 32 patients with a diagnosis of subclinical hypothyroidism and a control group of 30 healthy individuals were tested for high-sensitivity C-reactive protein and fetuin-A, followed by the administration of 50 µg of levothyroxine in the patient group for 3 months. During the post-treatment stage, high-sensitivity C-reactive protein and fetuin-A levels in the patient group were re-assessed and compared with pre-treatment values. RESULTS: Pre-treatment levels of both high-sensitivity C-reactive protein and fetuin-A were observed to be higher in the patient group than in the control group. The decrease in high-sensitivity C-reactive protein levels during the post-treatment stage was not statistically significant. However, the decrease observed in post-treatment fetuin-A levels was found to be statistically significant. CONCLUSION: The decrease in fetuin-A levels in subclinical hypothyroidism cases indicates that levothyroxine treatment exerts anti-inflammatory and anti-apoptotic effects. Although the decrease in high-sensitivity C-reactive protein levels was statistically non-significant, it is predicted to reach significance with sustained treatment.

    Amongst patients with incurable cancer approaching death, cachexia is common and associated with adverse outcomes. The term cachexia lacks a universally accepted definition and there is no consensus regarding which variables are to be measured. Furthermore, an elevated C-reactive protein is a common clinical challenge in this patient group. This study aims to add to the ongoing discussion regarding the definition of cancer cachexia and to study the role of C-reactive protein and s-albumin in this context. A 1-year cohort, consisting of 155 cancer patients enrolled in a specialized palliative home care team in the city of Östersund, Sweden, that were deceased during the year of 2015 was studied. Laboratory measures were studied within 0-30 and 31-60 days prior to death. C-reactive protein >10 mg/L and coinciding s-albumin death was noted. The prevalence of "laboratory cachexia" was 85% 0-30 days prior to death compared to 66% 31-60 days prior to death (pdeath, with a median of 47 days. The median values for C-reactive protein and s-albumin within 0-30 days prior to death were 84mg/L and 23g/L respectively. Could markedly deranged values of C-reactive protein and s-albumin, such as found in this study, signal a relatively short remaining survival time in patients with incurable cancer and no clinical signs of ongoing infection? The role of "laboratory cachexia" in this context as well as the cut off values for the laboratory measures included may be further discussed.

    Procalcitonin is a surrogate infection blood marker whose levels help estimate the likelihood of bacterial infections and correlate with their resolution. Recent trials have revealed the benefits of inclusion of procalcitonin in antibiotic stewardship protocols for initiation and discontinuation of antimicrobial therapy. Areas covered: Procalcitonin-guided antibiotic stewardship protocols have shown appreciable reductions in antibiotic use and duration of therapy in respiratory infections, sepsis, and other infections, with positive effects on clinical outcomes. Multiple fully automated and sensitive procalcitonin assays are routinely used in clinical practice. Utilization of these assays requires consideration of the clinical setting and knowledge of assay characteristics, particularly assay sensitivities, reproducibility, and performance across routinely used cut-off ranges. The authors provide an overview of the strengths and limitations of currently available procalcitonin assays and antibiotic therapy algorithms incorporating procalcitonin currently used in different clinical settings and in patients with different underlying infections. Expert commentary: Use of sensitive procalcitonin measurements in clinical algorithms can reduce antimicrobial overuse, decreasing the risk of side effects and controlling emerging bacterial multi-resistance. Before use in clinical practice, it is important to carefully assess the quality of novel PCT assays and rigorously evaluate them in target patient populations across clinically relevant cut-off ranges.

    Full Text Available C-reactive protein (CRP is a commonly used tool in emergency department (ED, especially in febrile and infectious patients. It was identified in 1930 and was subsequently classified into an “acute phase protein”, an early indicator of infectious or inflammatory situations in the ED, CRP must be a diagnostic reference and no single value can be indicated to rule in or rule out a specific diagnosis or disease. CRP is a comprehensively assisted tool for evaluation and diagnosis of tissue damage (rheumatologic diseases, stroke, cancer, pancreatitis, burn injury, sepsis and gout and infection (urinary tract infection, pelvic inflammatory disease, meningitis and lung infection. It can be used for treatment monitoring and severity evaluation in pneumonia, pancreatitis, pelvic inflammatory disease (PID, and urinary tract infections (UTI. Otherwise, it also plays the role of prognostic indicator of acute coronary syndrome. C-reactive protein adds little to the diagnosis of pneumonia, urinary tract infections, and pancreatitis. A single CRP value should not straightly make the decision to treat these patients. That is, CRP has no role in diagnosing these clinical entities, and a normal CRP level should never delay antibiotic coverage in ED. Faster and more interpretable tools such as image studies (X-ray, sonography and computed tomography are available to help diagnose suspected cases of aortic dissection, appendicitis, cholecystitis, pancreatitis, pneumonia and stroke in ED.

    Full Text Available Introduction. Early assessment of the severity and etiology of acute pancreatitis is very important for further treatment procedures. The aim of the study was to investigate the association between intra-abdominal pressure (IAP and procalcitonin as an indicator of severity of acute pancreatitis. Method. The IAP is measured every 12 hours through the urinary catheter placed in the bladder, in 65 patients with acute pancreatitis. Procalcitonin is measured within 24 hours of receipt of the patient, after 48 hours and after 78 hours. These values of procalcitonin and IAP were compared to each other and in relation to the Acute Physiology, Age and Chronic Health Evaluation II (APACHE II scoring system. Patients with APACHE II score > 8 are defined with moderate and severe acute pancreatitis. Results. The values of IAP (18,1 ± 4,5 mmHg vs 8,9 ± 2,67 mmHg; p = 0,01 , procalcitonin (15,43 + 2,25 ng/ml vs 3,14 + 1,12 ng/ml; p =0,031 and APACHE II scoring system (17,3 ± 6,24 vs 6,5 ± 1,0; p = 0,013 were significantly higher in patients with moderate and severe acute pancreatitis. The increase in the value of IAP was accompanied by an increase in the value of procalcitonin (r = 0,581, p = 0,01. The sensitivity in the prediction of severe acute pancreatitis after 24 hours of receiving the patient is 91,7% for the IAP, 87,8% for procalcitonin and 84,9% for APACHE II scoring system. Conclusion. The increase in the value of the IAP is accompanied by an increase in the values of procalcitonin, also patients with higher values of APACHE II scoring sys­tem have higher values of IAP and procalcitonin. The values of IAP and procalcitonin can be used as markers of acute pancreatitis severity.

    Animals treated with anticonvulsant drugs may have increased canine pancreas-specific lipase (cPLI) values. Inflammatory conditions and specifically acute pancreatitis are of major concern in these animals. Elevation in C-reactive protein is being associated with inflammatory status in dogs and it has been correlated with the clinical severity of pancreatitis. In the present study, we investigated if there is a correlation between the cPLI increase, changes in C-reactive protein and hepatic enzymes, as well as the incidence of severe acute pancreatitis (AP) in dogs with anticonvulsant treatment (phenobarbital, or potassium bromide or both). Increased values of pancreas-specific lipase were found in 6.8% of the animals in treatment with anticonvulsants, and this increase is correlated with the increase in triglycerides, alkaline phosphatase, and alanine aminotransferase but not with C-reactive protein levels, which suggests a possible induction or release phenomenon rather than a clear severe AP. C-reactive protein levels did not affect cPLI values on the population studied. Only 2 animals had clinical and analytical data suggestive of AP, indicating a low prevalence (0.6%). In conclusion, cPLI may be increased in a low percentage of animals with anticonvulsants treatment and its increase may not be associated with severe AP. It may be induced by the anticonvulsants drugs; however, further studies are advised to rule out other possible causes that increased cPLI. Copyright © 2015 Elsevier Inc. All rights reserved.

    The optimal practice management of highly febrile 1- to 3-month-old children without a focal source has been controversial. The release of a conjugate pneumococcal vaccine may reduce the rate of occult bacteremia and alter the utility of empiric testing. The objective of this study was to determine the cost-effectiveness of 3 different screening strategies of Serious Bacterial Infections (SBI) in Children Presenting with Fever without Source in Argentina. Cost-effectiveness (CE) analysis was performed to compare the strategies of procalcitonin, C reactive protein and Rochester criteria. A hypothetical cohort of 10 000 children who were 1 to 3 months of age and had a fever of >39°C and no source of infection was modeled for each strategy. Our main outcome measure was incremental CE ratios. C reactive protein result in US$ 937 per correctly diagnosed cases of SBI. The additional cost per additional correct diagnosis using procalcitonin versus C reactive protein was U$6127 while Rochester criteria resulted dominated. C reactive protein is the strategy more cost-effective to detect SBI in children with Fever without Source in Argentina. Due to low proportion of correctly diagnosed cases (< 80%) of three tests in the literature and our study, however; an individualized approach for children with fever is still necessary to optimize diagnostic investigations and treatment in the different emergency care settings. © 2013 International Society for Pharmacoeconomics and Outcomes Research (ISPOR) Published by International Society for Pharmacoeconomics and Outcomes Research (ISPOR) All rights reserved.

    In patients with acute nonvariceal upper gastrointestinal bleeding, rebleeding after an initial treatment is observed in 10-20% and is associated with mortality. To investigate whether the initial serum C-reactive protein level could predict the risk of rebleeding in patients with acute nonvariceal upper gastrointestinal bleeding. This was a retrospective study using prospectively collected data for upper gastrointestinal bleeding. Initial clinical characteristics, endoscopic features, and C-reactive protein levels were compared between those with and without 30-day rebleeding. A total of 453 patients were included (mean age, 62 years; male, 70.9%). The incidence of 30-day rebleeding was 15.9%. The mean serum C-reactive protein level was significantly higher in these patients than in those without rebleeding (Pupper gastrointestinal bleeding, indicating a possible role as a useful screening indicator for predicting the risk of rebleeding.

    Background Psoriasis has been associated with co-morbidities and elevated cardiovascular risk. Objectives To analyze the relationships among metabolic syndrome, cardiovascular risk, C-reactive protein, gender, and Psoriasis severity. Methods In this cross-sectional study, plaque Psoriasis patients (n=90), distributed equally in gender, were analyzed according to: Psoriasis Area and Severity Index, cardiovascular risk determined by the Framingham risk score and global risk assessment, C-reactive protein and metabolic syndrome criteria (NCEPT-ATP III). Results Metabolic syndrome frequency was 43.3% overall, without significance between genders (P=0.14); but women had higher risk for obesity (OR 2.56, 95%CI 1.02-6.41; P=0.04) and systemic arterial hypertension (OR 3.29, 95%CI 1.39-7.81; P=0.006). The increase in the Psoriasis Area and Severity Index also increased the risk for metabolic syndrome (OR 1.060, 95%CI 1.006-1.117; P=0.03). Absolute 10-year cardiovascular risk was higher in males (P=0.002), but after global risk assessment, 51.1% patients, 52.2% women, were re-classified as high-intermediate cardiovascular risk; without significance between genders (P=0.83). C-reactive protein level was elevated nearly six-fold overall, higher in metabolic syndrome (P=0.05), systemic arterial hypertension (P=0.004), and high-intermediate 10-year cardiovascular risk patients (Preactive protein patients (t=1.98; P=0.05). Study limitations Restricted sample, hospital-based and representative of a single center and no specification of psoriatic arthritis. Conclusions Psoriasis, metabolic syndrome, systemic arterial hypertension and age share the increase in C-reactive protein, which could implicate in additional burden for increasing the cardiovascular risk and be an alert for effective interventions.

    Full Text Available Severe acute malnutrition and acute systemic infection are often synergistic in children and lead to considerable mortality. The main aim of this research was to determine whether children with severe acute malnutrition can mount an acute phase reactant response measured by C-reactive protein. This was a descriptive, cross-sectional, hospital-based study that was carried out in the five main children hospitals in Khartoum state, from November 1st, 2012 to March 1st, 2013. 132 children with severe acute malnutrition were included in the study. Data collection included history, examination and C-reactive protein measurement. The data were analyzed using Statistical Package for Social Sciences (SPSS for descriptive and inferential statistics. The main results revealed that 93(70.5% children between 12-23 months of age and most of them had marasmus. Diarrhoea was the commonest presenting symptoms in 86.4%, followed by fever and vomiting. Most of the children (82.6% had positive C-reactive protein with variable levels. In conclusion malnourished children are able to synthesize C-reactive protein in response to an infectious process and the magnitude of this response is increased in those with severe infections.

    Full Text Available Background and Aim: Urinary tract infection (UTI in children is among the prevalent infections of childhood, which occurs due to growth of bacteria in the urinary tract. The aim of this study was to evaluate the usefulness of procalcitonin (PCT as a reliable marker for distinguishing urinary tract infection (UTI with or without renal parenchyma (cystitis. Materials and Methods: Eighty children, who were suspicious of having UTI and had been referred to Ali Ibne Abitaleb hospital (in Zahedan or pediatric clinics (June 2007- Oct 2009 were included in the study after their urine culture revealed their infection. Besides, their clinical and lab symptoms including erythrocyte sedimentation rate (ESR, C– reactive protein (CRP, serum WBC, and serum procalcitonin (PCT were recorded. The patients were divided into two groups based on their lab clinical symptoms and radio-isotope scans, namely acute pyelonephritis and acute cystitis (lower UTI. Serum procalcitonin was measured in these cases in a semi-quantitative manner. Results: Fifty children with mean age of 4.89±3.50 years were compared with 30 children with mean age of 5.20±3.07 years. ESR, WBC, and PCT were significantly higher in patients with upper UTI (P<0.001 , but CRP was not significantly different in the two groups. PCT, which was semi-quantitatively measured, when lower than 0.5 had a relationship with sensitivity, specificity, positive predictive value, and negative value of 72%, 83.3%, 87.8%, and 64.1% respectively. When PCT was more than 2, the relationship with the mentioned features was 50%, 96.6%, 96.2%, and 53.7%, respectively. The relationships in these two domains can both be assistant in differentiating pyelonephritis from cystitis. Conclusion: PCT was more sensitive and specific for the diagnosis of upper versus lower UTI compared with CRP, and it can be a better marker than CRP for early prediction of febrile pyelonephritis in children.

    This study was designed to show the effect of propylthiouracil treatment on sCD40L, high-sensitivity C-reactive protein, and fetuin-A levels on subjects with subclinical hyperthyroidism. After checking sCD40L, high-sensitivity C-reactive protein, and fetuin-A levels of 35 patients with subclinical hyperthyroidism, each was given 50 mg tablets of propylthiouracil three times daily. After 3 months, sCD40L, high-sensitivity C-reactive protein, and fetuin-A levels were then compared to the levels before treatment. Although high-sensitivity C-reactive protein and sCD40L levels were normal in the subclinical hyperthyroidism patients compared to the healthy controls, fetuin-A levels were statistically significantly higher (*p = 0.022). After treatment, fetuin-A levels of subclinical hyperthyroidism patients decreased statistically significantly compared to the levels before treatment (**p = 0.026). sCD40L and high-sensitivity C-reactive protein levels did not have a statistically significant difference compared to the control group and post-propylthiouracil treatment. In subclinical hyperthyroidism patients, high fetuin-A levels before propylthiouracil treatment and decreases in these levels after treatment in cases with subclinical hyperthyroidism indicated the possibility of preventing long-term cardiac complications with propylthiouracil treatment.

    2009-10-01

    Avian pneumovirus subgroup C (APV/C) has recently been reported to be more closely related to human metapneumovirus (hMPV) as determined by sequence analysis. To examine the antigenic relationship between APV/C and hMPV, the APV/C fusion (F) gene was cloned and expressed as an uncleaved glycoprotein in a baculovirus system. The reactivity of the APV/C F protein with antibodies against APV subgroups A, B, C, and hMPV was examined by Western blot analysis. The results showed that the expressed APV/C F protein was not only recognized by APV/C-specific antibodies but also by antibodies raised against hMPV. Previously expressed recombinant hMPV F protein also reacted with APV/C-specific antibodies, suggesting that there was significant antigenic cross-reactivity and a potential evolutionary relationship between hMPV and APV/C. Interestingly, the recombinant F proteins from APV/C and hMPV were not recognized by polyclonal antibodies specific to APV subgroups A and B.

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

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

    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. © 2016 by the American Anthropological Association.

    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.

    Crystals of native and selenomethionine-substituted C-reactive protein from zebrafish diffracted to 2.3 and 1.7 Å resolution, respectively, and belonged to space group R3 with one molecule per asymmetric unit. The Matthews coefficient was calculated to be 3.28 Å 3 Da −1 . C-reactive protein (CRP) is an acute phase protein that is found in blood, the concentration of which in plasma rises rapidly in response to inflammation. It functions as a pattern-recognition molecule, recognizing dead cells and various pathogenic agents and eliminating them by utilizing the classical complement pathway and activating macrophages. CRP is phylogenetically highly conserved in invertebrates and mammals. To date, information on the CRP gene has been reported from numerous species of animals, but little is known about the structure of CRP from species other than humans. In order to solve the structure of CRP from bony fish, the CRP gene from zebrafiah (Danio rerio) was cloned and expressed in Escherichia coli. The zebrafish CRP (Dare-CRP) was then purified and crystallized. The crystal diffracted to 2.3 Å resolution and belonged to space group R3, with unit-cell parameters a = b = 114.7, c = 61.0 Å. The Matthews coefficient and solvent content were calculated to be 3.28 Å 3 Da −1 and 62.55%, respectively. Determination of the zebrafish CRP structure should be helpful in investigating the evolution of CRPs in the innate immune system

    C-reactive protein (CRP) is an acute-phase reactant whose serum level rises rapidly in response to tissue injury. C-reactive protein binding to cells can activate the classical complement pathway, and enhance opsonophagocytosis. The polycation poly-L-arginine (PLA) can artificially fix CRP to target cells. The effects of CRP and PLA on tumor growth were evaluated, both independently and synergistically, using the V X 2 tumor line in the rabbit host. Ten normal animals and seven acute-phase animals were bilaterally inoculated with V X 2 cells (control side) and PLA-treated V X 2 cells (experimental side). Tumor growth was significantly retarded on the treatment side (P less than 0.005), in both animal groups. It is concluded that topical PLA is a potent inhibitor of V X 2 tumor growth. Comparison of normal and acute-phase animals revealed no persistent difference in tumor growth for either cell inoculum. Similarly, cell treatment with topical CRP did not inhibit tumor growth, whether PLA was present or not. Thus, circulating and topical CRP did not alter the rate of V X 2 tumor growth. PLA cytotoxicity remains to be evaluated when the agent is administered orthotopically, selectively, or systemically.

Patients were divided into three groups based on their semiquantitative procalcitonin concentrations (group A, <2 ng/mL; group B ≥ 2 ng/mL < 10 ng/mL; group C ≥ 10 ng/mL.Results: A significant difference in DIC, SOFA, and APACHE II scores was found between group A and group C and between group B and group C (P < 0.01. Patients with severe sepsis and septic shock had significantly higher procalcitonin concentrations than did patients with less severe disease. The rate of patients with septic shock with high procalcitonin concentrations showed an upward trend. There was a significant (P < 0.01 difference between the three groups with regard to numbers of patients and rates of severe sepsis, septic shock, DIC, and mortality.Conclusion: Semiquantitative procalcitonin concentration testing can be helpful for early assessment of disease severity in patients with sepsis.

    Several studies suggested an association between periodontal disease and cardiovascular disease (CVD). C- reactive protein is elevated in periodontitis patients and has been found to be a predictor of increased risk for cardiovascular disease. Since, CRP is known to play a role in pathogenesis of atherosclerosis, the present study was undertaken to evaluate the serum levels of CRP in periodontitis patients with or without atherosclerosis. A total of 45 patients, 15 chronic periodontitis patients with atherosclerosis (Group A), 15 chronic periodontitis patients with no history of any systemic disease (Group B), and 15 clinically healthy individuals with no history of periodontal or systemic disease (Group C) within age range of 30 to 55 years were selected for the study. PI, PBI, PPD, CAL and radiographic marginal alveolar bone level were assessed in all the three groups. CRP levels were assessed with 'Turbi-latex' kit using turbidimetric analysis. The mean CAL recorded was 4.9mm in group A, 4.6mm in group B and 1.9 mm in group C. The mean radiographic marginal bone level was 45 to 50% in group A, 45 to 50% in group B and 90 to 95% in group C. Mean serum C-reactive protein level was significantly higher in group A (8.9 mg/l), as compared to group B (4.9 mg/l) as well as group C (0.9 mg/l). Within the limits of this study it was concluded that periodontitis may add to the inflammatory burden of the individual and may result in increased risk of atherosclerosis based on serum C-reactive protein concentrations.

  1. Production of C-reactive protein by human lymphocytes

    Kuta, A.E.; Baum, L.L.

    1986-01-01

    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 35 S-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

    Periodontitis may affect atherosclerosis via the chronic inflammation. We investigated high-sensitivity C-reactive protein (hsCRP) in relation to early vascular atherosclerotic changes in non-symptomatic subjects with and without long-term periodontitis. Carotid ultrasonography with calculation of common carotid artery intima-media area (cIMA) was performed, and hsCRP and atherosclerosis risk factors were analysed in randomly chosen 93 patients with periodontitis and 41 controls. The relationship between hsCRP, cIMA and atherosclerosis risk factors was evaluated with multiple logistic regression analysis. Women displayed lower hsCRP (p periodontitis, cIMA values were higher than in controls. Periodontitis appeared to be a major predictor for increased cIMA (odds ratio, 3.82; 95% confidence interval, 1.19-12.26). Neither of these factors was significantly associated with hsCRP which thus appeared not sensitive enough to be a marker for periodontitis or atherosclerosis. Hence, irrespective of low hsCRP levels, periodontitis appeared to increase the risk for atherosclerosis.

    In patients radically treated for differentiated thyroid carcinoma, we assessed the response of highly-sensitive C-reactive protein, an inflammatory biomarker for cardiovascular risk, after thyroid hormone withholding ("deprivation"), as well as factors potentially influencing this response. We included 52 adults (mean age 45.6±14.0 years, 35 females) who were disease-free after total thyroidectomy, radioiodine ablation and chronic thyroid hormone therapy. They were lifelong non-smokers without apparent inflammatory comorbidity, cardiovascular history beyond pharmacotherapy-controlled hypertension, anti-dyslipidemic medication, or C-reactive protein >10 mg/L in any study measurement. The index deprivation lasted ≥2 weeks, elevating serum thyrotropin >40 mIU/L or ≥100 × the individual's suppressed level. We examined the relationship of age, number of prior deprivations, and gender with the magnitude of post-deprivation C-reactive protein concentration through multivariable statistical analyses using the F test on linear regression models. Post-deprivation, C-reactive protein reached intermediate cardiovascular risk levels (based on general population studies involving chronic elevation), 1-3 mg/L, in 44.2% of patients and high-risk levels, >3 mg/L, in another 17.3%. Mean C-reactive protein was 1.77±1.50 mg/L, differing significantly in females (2.12±1.66 mg/L) vs. males (1.05±0.69 mg/L, P <0.001). In multivariable analysis, patients ≤45 years old (odds ratio, 95% confidence interval 0.164 [0.049-0.548]) were less likely, and females, more likely (3.571 [1.062-12.009]) to have post-deprivation C-reactive protein ≥1 mg/L. Thyroid hormone withdrawal frequently elevated C-reactive protein to levels that when present chronically, were associated with increased cardiovascular risk in general population studies. © J. A.

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

    The diagnostic performance of canine serum amyloid A (SAA) was compared with that of C-reactive protein (CRP) in the detection of systemic inflammation in dogs. Sera from 500 dogs were retrospectively included in the study. C-reactive protein and SAA were measured using validated automated assays....... The overlap performance, clinical decision limits, overall diagnostic performance, correlations, and agreement in the clinical classification between these 2 diagnostic markers were compared. Significantly higher concentrations of both proteins were detected in dogs with systemic inflammation (SAA range: 48.......75 to > 2700 mg/L; CRP range: 0.4 to 907.4 mg/L) compared to dogs without systemic inflammation (SAA range: 1.06 to 56.4 mg/L; CRP range: 0.07 to 24.7 mg/L). Both proteins were shown to be sensitive and specific markers of systemic inflammation in dogs. Significant correlations and excellent diagnostic...

    Chorioamnionitis (CAM) affects many pregnancies complicated by preterm premature rupture of membranes (PPROM). Finding a serum factor that could accurately predict the presence of CAM could potentially lead to more efficient management of PPROM and improved neonatal outcomes. To determine if C-reactive protein (CRP) is an effective early marker of CAM in patients with PPROM. A retrospective evaluation of pregnant women with PPROM at Geisinger Medical Center in Danville, Pennsylvania, between January 2005 and January 2009. Nonparametric statistical tests (ie, Wilcoxon rank sum and Spearman rank correlation) were used to compare distributions that were skewed. Characteristics of the study population were compared using 2-sample t tests for continuous variables and Fisher exact tests for discrete variables. Logistic regression analysis was used to generate receiver operating characteristic curves and obtain area under the curve estimates in stepwise fashion for predicting histologic CAM. A secondary analysis compared the characteristics among patients with clinical CAM, histologic CAM, or non-CAM. The total population of 73 women was subdivided into patients with histologic CAM (n=26) and patients without histologic CAM (ie, no evidence of CAM on placental pathology; n=47). There was no difference between groups in CRP levels, days of pregnancy latency, white blood cell count, smoking status, antibiotic administration, or steroid benefit. The group with histologic CAM delivered at earlier gestational ages: mean (standard deviation) age was 29.5 (4.4) weeks vs 31.9 (3.5) weeks (P=.02). For our primary analysis, we found no difference in CRP levels (P=.32). Receiver operating characteristic curve plots of CRP levels, temperature at delivery, and white blood cell count resulted in an area under the curve estimate of 0.696, which was 70% predictive of histologic CAM. In the secondary analysis, after adjusting for gestational age, the estimated hazard ratio for CRP change

    Full Text Available Temporomandibular joint dysfunction is a functional disorder concerned with the abnormal functioning of the muscles of the stomatognathic system and temporomandibular joints involved in the dynamic movements of the jaw and surrounding structures. The aim of the study was to compare the level of C-reactive protein in patients with pain and painless forms of temporomandibular joint dysfunction. Materials and methods. The study group consisted of 72 patients who reported to the prosthetic treatment because of temporomandibular joint dysfunction. The study group included 36 patients with pain form of dysfunction, and the control group included 36 patients with painless form of disorder. Each patient underwent specialized examination of functional disorders in order to diagnose the type of dysfunction and was commissioned to carry out a study of the blood test concerned with evaluation of the C-reactive protein (CRP level in the same analytical laboratory. The results of the investigation were subjected to statistical analysis. The research obtained approval from the Ethics Committee of the Jagiellonian University (KBET/125/L/2013. Level of Evidence for primary research was established as type V. Results. The mean values of C-reactive protein levels in both groups were in the normal range and did not differ statistically significantly, which indicates the fact that the pain form of the temporomandibular joint disorders is not associated with inflammation of the soft tissues of the joint. Conclusion. Painful form of the temporomandibular joint dysfunctions is not connected with the inflammation of joints.

    2015-02-01

    There is growing evidence that bipolar disorder (BD) is associated with inflammation, including abnormal levels of acute-phase C-reactive protein (CRP). Our meta-analysis was conducted to estimate the size of the association between CRP levels and BD, accounting also for subgroup differences (mood phases and treatment). MEDLINE, EMBASE, PsycINFO, and ISI Web of Science and references of identified articles were searched up to June 2013 using the keywords (bipolar disorder) AND (C-reactive protein OR CRP). English language studies measuring blood levels of CRP in patients with BD and control subjects were selected, 136 abstracts were reviewed, 20 articles retrieved, and 11 studies included. Two independent reviewers extracted data. All studies were included in the primary analyses, and between-group differences for subanalyses were also reported. This meta-analysis was performed using random-effects models. Eleven studies comprising 1,618 subjects were eligible for inclusion. Overall, CRP levels were significantly elevated in patients with BD versus controls (standardized mean difference [SMD] = 0.39; 95% CI, 0.24 to 0.55; P < .0001). CRP levels were significantly higher in manic (SMD = 0.73; 95% CI, 0.44 to 1.02; P < .001) and euthymic (SMD = 0.26; 95% CI, 0.01 to 0.51; P = .04), but not in depressed (SMD = 0.28; 95% CI, -0.17 to 0.73; P = .22) patients with BD compared to controls. CRP levels were unrelated to use of lithium or antipsychotic medication. This meta-analysis supports an association between increased CRP levels and BD. Given that an elevated level of CRP is a marker of low-grade inflammation and a risk factor for cardiovascular and malignant diseases, measurement of CRP level might be relevant to the clinical care of bipolar patients. © Copyright 2015 Physicians Postgraduate Press, Inc.

    Using data from the Third National Health and Nutrition Examination Survey (1988-1994), the authors examined the relation between periodontal health and cardiovascular risk factors: serum total and high density lipoprotein cholesterol, C-reactive protein, and plasma fibrinogen. A total of 10,146 participants were included in the analyses of cholesterol and C-reactive protein and 4,461 in the analyses of fibrinogen. Periodontal health indicators included the gingival bleeding index, calculus index, and periodontal disease status (defined by pocket depth and attachment loss). While cholesterol and fibrinogen were analyzed as continuous variables, C-reactive protein was dichotomized into two levels. The results show a significant relation between indicators of poor periodontal status and increased C-reactive protein and fibrinogen. The association between periodontal status and total cholesterol level is much weaker. No consistent association between periodontal status and high density lipoprotein cholesterol was detectable. Similar patterns of association were observed for participants aged 17-54 years and those 55 years and older. In conclusion, this study suggests that total cholesterol, C-reactive protein, and fibrinogen are possible intermediate factors that may link periodontal disease to elevated cardiovascular risk.

    Measurement of C-reactive protein, a marker of inflammation, in dried blood spots has been increasingly incorporated in community-based social surveys internationally. Although the dried blood spot based CRP assay protocol has been validated in the United States, it remains unclear whether laboratories in other less developed countries can generate C-reactive protein results of similar quality. We therefore conducted external quality monitoring for dried blood spot based C-reactive protein measurement for the Indonesia Family Life Survey and the Longitudinal Aging Study in India. Our results show that dried blood spot based C-reactive protein results in these two countries have excellent and consistent correlations with serum-based values and dried blood spot based results from the reference laboratory in the United States. Even though the results from duplicate samples may have fluctuations in absolute values over time, the relative order of C-reactive protein levels remains similar and the estimates are reasonably precise for population-based studies that investigate the association between socioeconomic factors and health.

    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.

    Procalcitonin has been found to be a good marker for the diagnosis of sepsis. However, data on procalcitonin levels to predict the clinical outcome in patients with sepsis are limited. The aim of our study was to estimate serum procalcitonin levels in patients with sepsis and to identify its relationship with the clinical outcome. This was a prospective observational study conducted on 112 patients with sepsis admitted to the medical wards and medical intensive care unit of a tertiary care teaching hospital. Serum procalcitonin was measured at baseline before antibiotic administration and on day 5. The clinical outcome studied was death or survival on day 28. Baseline mean serum procalcitonin was highest in patients with septic shock and lowest in patients having sepsis without organ dysfunction. Mean values of procalcitonin at baseline and on day 5 were significantly higher in non-survivors when compared with survivors. There was a significant difference in the change in procalcitonin levels from baseline to day 5 between survivors and non-survivors, with survivors having declining values on day 5 while non-survivors had increasing values from baseline. The baseline APACHE II and SOFA scores also showed a significant correlation with the baseline procalcitonin level. Declining values of procalcitonin therefore indicate a favourable clinical outcome in patients with sepsis.

    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.

    Full Text Available Inflammation is widely considered to be an important contributing factor of the pathophysiology of coronary heart disease (CHD, and the inflammatory cascade is particularly important in the atherosclerotic process. In consideration of the important role that inflammatory processes play in CHD, recent work has been focused on whether biomarkers of inflammation may help to improve risk stratification and identify patient groups who might benefit from particular treatment strategies. Of these biomarkers, C-reactive protein (CRP has emerged as one of the most important novel inflammatory markers. CRP an acute phase protein is synthesized by hepatocytes in response to proinflammatory cytokines, in particular interleukin-6. Many large-scale prospective studies demonstrate that CRP strongly and independently predicts adverse cardiovascular events, including myocardial infarction, ischemic stroke, and sudden cardiac death in individuals both with and without overt CHD. CRP is believed to be both a marker and a mediator of atherosclerosis and CHD. CRP plays a pivotal role in many aspects of atherogenesis including, activation of complement pathway, lipids uptake by macrophage, release of proinflammatory cytokines, induces the expression of tissue factor in monocytes, promotes the endothelial dysfunction and inhibits nitric oxide production. The commercial availability of CRP high sensitive assays has made screening for this marker simple, reliable, and reproducible and can be used as a clinical guide to diagnosis, management, and prognosis of CHD.

    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.

    In order to establish the most reliable marker for distinguishing urinary tract infections (UTI) with and without renal parenchymal involvement (RPI), we recorded the clinical features and admission leukocyte count, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and serum procalcitonin (PCT) in 57 children (including 43 girls) aged 2-108 months admitted with a first episode of UTI. RPI was evaluated by Tc-99m dimercaptosuccinic acid (DMSA) scintigraphy within 7 days of admission. To establish cut-off points for ESR, CRP, and PCT, we used receiver operating characteristics curves and compared the area under the curve for ESR, CRP, and PCT. Twenty-seven children were diagnosed as having RPI based on positive renal scintigraphy. A body temperature of >38 degrees C, a history of diarrhea, and poor oral intake were more common in patients with RPI. ESR, CRP, and PCT, but not leukocyte count, were significantly higher in patients with RPI (P UTI than ESR and CRP. Using a cut-off value of 0.85 ng/ml, PCT had the best performance, with sensitivity, specificity, and positive and negative predictive values of 89%, 97%, 96%, and 91% respectively. Serum PCT is a better marker than ESR, CRP, and leukocyte count for the early prediction of RPI in children with a first episode of UTI.

    Two new, rapid and sensitive radioimmunoassays for human C-reactive protein (CRP) have been established using antiserum coupled to magnetizable cellulose particles, which facilitate phase separation. A single antibody method, using solid phase anti-CRP, provides a sensitivity of 50 μg/l with a 1-h incubation time and intra- and inter-assay coefficients of variation of 10%. A double antibody method, using fluid phase rabbit anti-CRP serum and solid phase sheep anti-rabbit IgG serum, provides a sensitivity of 3 μg/l with an overnight incubation and intra- and inter-assay coefficients of variation of 10%. Among 468 sera from normal adult volunteer blood donors the median CRP concentration was 800 μg/l, interquartile range 340-1700 μg/l and range 70-29,000 μg/l. Ninety percent of samples contained less than 3 mg/l and 99% less than 10 mg/l. Low levels (14-650 μg/l) of CRP were detected both in amniotic fluids and in cerebrospinal fluids. (Auth.)

    Periodontal subgingival pathogens affect local and systemic immune and inflammatory response and cause the release of cytokines; this results in periodontal destruction and initiation of an acute phase systemic inflammatory response characterized by the release of C-reactive proteins (CRP). This study set out to evaluate the serum concentration of CRP that can be used as a marker of periodontal disease as well as a risk indicator for cardiovascular disease. Based on their periodontal status, 45 patients were divided into three groups. The following clinical parameters were recorded: plaque index, gingival index, bleeding index, probing pocket depth, and clinical attachment levels. Scoring was done on six tooth surfaces for all teeth. For the CRP assessment, blood samples were collected from subjects at the time of clinical examination. The results indicated an increase in serum CRP levels in patients with generalized aggressive periodontitis and chronic periodontitis as compared to controls.

    Full Text Available Background: Preeclampsia is a multisystem disorder of unknown etiology characterized by development of hyperten­sion to the extent of 140/90 mm of Hg or more with proteinuria after the 20th gestational week in a previously normoten­sive and non protein uric women. According to the National High blood presure Working group (NHBPEP and Ameri­can college of obstetricans and Gynecologiests (ACOG hypertension in pregnancy is defined as a diastolic blood pressure of 90 mm Hg or higher after 20 weeks of gestation in a woman with previously normal blood pressure (NHBPEP, 2000; ACOG, 2002. If the disease is allowed to progress to the HELLP syndrome or eclampsia, maternal morbidity and mortality increases. The majority of perinatal losses are related to placental insufficiency, which causes intrauterine growth retardation, prematurity associated with preterm delivery, or abruptio placentae. Objectives: This study tried to explore the effect of serum C reactive protein concentration in preeclamptic women and its effect on pregnancy outcome.Methods: This case control study included 60 third trimester pregnant women (30 normotensive and 30 preeclamptic who attended Department of Obstetrics and Gynaecology, BIRDEM and DMCH, during July 2009 and June 2010. Estimation of serum C reactive protein (CRP concentrations was done by liquid phase immunoprecipitation assay and turbulometry at DMC.Results: Mean (±SD age showed no significant difference between groups; however, BMI, SBP, DBP and CRP were significantly (P<0.001 high in case group. Gravidity and ANC showed no significant variation between groups. CRP concentration was significantly high case group. Gestational age was significantly low in case group resulting in higher preterm delivery. No significant variation was observed regarding fetal outcome; however, birth weight was significantly low and neonatal complication was also significantly high in case group.Conclusion: CRP concentration was high in

    Full Text Available Background: Periodontitis is an inflammatory disease caused by periodontal pathogens and influenced by multiple risk factors such as genetics, smoking habit, age and systemic diseases. The inflammatory cascade is characterized by the release of C-reactive protein (CRP. Periodontitis has been reported to have plausible links to increased level of CRP, which in turn has been associated to elevated risk of  cardiovascular disease (CVD. Purpose: The purpose of this study was t o investigate the relationship amongst the severity of periodontitis, CRP level in blood and CRP (-717 C>T gene polymorphism in male Indonesian smokers and non-smokers. Method: The severity of periodontitis was assessed for 97 consenting male Indonesian smokers and non-smokers. The CRP level of the subjects was determined by using immuno-turbidimetric assay performed in PARAHITA Diagnostic Center Laboratory ISO 9001: 2000 Cert No. 15225/2. The rate of CRP (-717C>T gene polymorphism was determined by using PCR-RFLP in Oral Biology Laboratory, Faculty of Dentistry, Universitas Indonesia. Result: The results suggest that the CRP protein level is not significantly associated with the tested CRP gene polymorphism (p>0.05. Also, while the severity of periodontitis increased significantly with subject age, the CRP level in blood serum was not significantly related to the severity of  periodontitis. The genotypes of the tested polymorphism did not show significant association with the severity of periodontitis either in smokers or in the combined population including smokers and non-smokers. The results naturally do not exclude such associations, but suggest that to discern the differences the sample size must be considerably increased. Conclusion: The CRP (-717C>T gene polymorphism and CRP level in blood serum were not found to be associated with the severity of periodontitis in male smokers or in the combined population of smokers and non-smokers.

    The ability of C-reactive protein (CRP) to activate macrophages to tumoricidal state was examined. CRP was able to activate macrophages to kill tumor cells. The activation was shown to be due to CRP and not to low levels of other activators present in the CRP preparations, since specific removal of CRP led to abrogation of the CRP mediated activation of macrophages. The role of lipopolysaccharide (LPS) as a contaminating activator was eliminated by showing the ability of CRP preparations to activate macrophages from LPS non-responsive strains of mice, and to activate macrophages under conditions which specifically inactivated or removed the contaminating LPS. In order to exclude the possibility of indirect activation of macrophages by other cells present in the peritoneal exudate cell population, effect of CRP on pure macrophages was examined. Bone marrow derived macrophages as well as well as macrophage cell lines exhibited a significant increase in their capacity to kill tumor cells after treatment with CRP. The nature of CRP and macrophage interaction was examined using radioiodinated CRP. Labelled CRP bound specifically to macrophages and macrophage cell lines

    To assess efficacy of C-reactive protein levels as monitoring tools for patients with fascial space infections of odontogenic origin. A randomized prospective study was conducted on 20 patients suffering from fascial space infection of odontogenic origin, in the department of Oral and Maxillofacial Surgery Bharati Vidyapeeth dental college and hospital, Pune, Patients between 18 and 60 years of age of both the sexes were selected. All patients were treated and observed by the same surgeon. Patient's venous blood sample was collected pre-operatively and on 2nd and 5th post-operative days for evaluation of WBC count and C-reactive protein (CRP). All patients were encouraged for strict follow-up protocol. Where the results of WBC count and CRP when compared it was seen that the mean values of WBC were normal in 15 cases and abnormal in 5 cases on day 0, day 2 and day 5; whereas the mean values of CRP were abnormal on day 0 and day 2 and were within normal limit on day 5 in all cases. The findings of this prospective analysis indicate that White blood cells and C-reactive protein are effective markers for determining severity of infection, efficacy of treatment regime for patients with fascial space infections of odontogenic origin. Thus the markers also help in making treatment of patients with fascial space infections of odontogenic origin more cost effective and they also help protecting patients from side effects of excess drugs usage. Thus we conclude that CRP should be incorporated as monitoring tools for managing patients with fascial space infections of odontogenic origin.

    Full Text Available C-reactive protein (CRP is one of the most expressed proteins in blood during acute phase inflammation, and its minute level increase has also been recognized for the clinical diagnosis of cardio vascular diseases. Unfortunately, the available commercial immunoassays are labour intensive, require large sample volumes, and have practical limitations, such as low stability and high production costs. Hence, we have developed a simple, cost effective, and label-free electrochemical immunoassay for the measurement of CRP in a drop of serum sample using an immunosensor strip made up of a screen printed carbon electrode (SPE modified with anti-CRP functionalized gold nanoparticles (AuNPs. The measurement relies on the decrease of the oxidation current of the redox indicator Fe3+/Fe2+, resulting from the immunoreaction between CRP and anti-CRP. Under optimal conditions, the present immunoassay measures CRP in a linear range from 0.4–200 nM (0.047–23.6 µg mL−1, with a detection limit of 0.15 nM (17 ng mL−1, S/N = 3 and sensitivity of 90.7 nA nM−1, in addition to a good reproducibility and storage stability. The analytical applicability of the presented immunoassay is verified by CRP measurements in human blood serum samples. This work provides the basis for a low-priced, safe, and easy-to-use point-of-care immunosensor assay to measure CRP at clinically relevant concentrations.

    The inflammatory mediators, serum elastase and C-reactive protein (CRP), are associated with an increased risk for coronary heart disease. Thus, the aim of this study is to compare systemic inflammatory mediators in periodontally healthy controls (C), patients with untreated aggressive (AgP) and chronic (ChP) periodontitis. C [periodontal pocket probing depth (PPD)  30% of sites; age >35 years), and AgP (clinically healthy; PDD ≥ 3.6 mm at >30% of sites, bone loss ≥50% at ≥2 teeth; age ≤35 years) were examined clinically, and the body mass index was assessed. Blood was sampled for assessment of serum levels of elastase, CRP, lipopolysaccharide binding protein (LBP), interleukin (IL) 6, 8, and leukocyte counts. Thirty C, 31 ChP, and 29 AgP were analyzed. Elastase, CRP, LBP, and IL-6 levels were elevated in AgP compared to C (p C. AgP patients exhibit a stronger systemic inflammatory burden than C patients.

    2017-01-01

    Full Text Available Purpose. Liver dysfunction and failure are severe complications of sepsis and result in poor outcome and increased mortality. The underlying pathologic mechanisms of hepatocyte dysfunction and necrosis during sepsis are only incompletely understood. Here, we investigated whether procalcitonin, a biomarker of sepsis, modulates liver cell function and viability. Materials and Methods. Employing a previously characterized and patented biosensor system evaluating hepatocyte toxicity in vitro, human hepatocellular carcinoma cells (HepG2/C3A were exposed to 0.01–50 ng/mL procalcitonin for 2×72 h and evaluated for proliferation, necrosis, metabolic activity, cellular integrity, microalbumin synthesis, and detoxification capacity. Acetaminophen served as positive control. For further standardization, procalcitonin effects were confirmed in a cellular toxicology assay panel employing L929 fibroblasts. Data were analyzed using ANOVA/Tukey’s test. Results. Already at concentrations as low as 0.25 ng/mL, procalcitonin induced HepG2/C3A necrosis (P<0.05 and reduced metabolic activity, cellular integrity, synthesis, and detoxification capacity (all P<0.001. Comparable effects were obtained employing L929 fibroblasts. Conclusion. We provide evidence for procalcitonin to directly impair function and viability of human hepatocytes and exert general cytotoxicity in vitro. Therapeutical targeting of procalcitonin could thus display a novel approach to reduce incidence of liver dysfunction and failure during sepsis and lower morbidity and mortality of septic patients.

    We showed that obese insulin resistant postmenopausal women are characterized by higher lean body mass and elevated C-reactive protein. Although counterintuitive, we hypothesized that losses in muscle mass following caloric restriction and increase in muscle quality will be associated with improvements in glucose homeostasis through decreases in C-reactive protein. To determine 1) if improvements in C-reactive protein concentrations occurs through losses in lean body mass; and 2) if decreases in C-reactive protein levels contribute to improvements in insulin sensitivity. 50 postmenopausal women (body mass index>26 kg/m(²)) with impaired glucose disposal (program. Outcome measures were: Glucose disposal rate: M value (by hyperinsulinemic-euglycemic clamp), body composition (total, trunk, and appendicluar). LBM and FM by DXA), LBM index (LBM (kg)/height (m(2)), body fat distribution (VAT and SAT by CT scan) and plasma high-sensitive C-reactive protein (hsCRP) and interleukin-6 (Il-6). Significant correlations were observed between Δ hsCRP levels with Δ Il-6 (r=0.33, p≤0.05), Δ total LBM index (r=0.44, p≤0.01), Δ trunk LBM (r=0.38, p≤0.01) Δ SAT (r=0.35, p≤0.05) and ∆ glucose disposal rate (r=- 0.44, p≤0.01). After including all the correlated variables in Stepwise linear regression model, Δ LBM index was the only independent predictor of the reduction in hsCRP levels (R(2)=0.20, p≤0.01). Losses in total lean body mass are independently associated with improvements in inflammatory state (CRP levels) in obese postmenopausal women with impaired glucose disposal. © Georg Thieme Verlag KG Stuttgart · New York.

    To investigate the relationship between C-reactive protein (CRP) + 1444C/T, CRP+1059G/C polymorphisms and chronic periodontitis (CP) in a Han Chinese population. Clinical periodontal parameters [attachment loss (AL) probing depth (PD) and bleeding on probing (BOP)], and serum CRP levels were examined in CP patients (n = 126) and healthy subjects (n = 113). The mean serum CRP level [(1.74 ± 1.67) mg/L] was significantly higher in the CP group than in the control group [(0.57 ± 0.39) mg/L], P C allele was 6.7% (17/252) in the CP group and 4.9% (11/226) in the control group. The percentage of CRP + 1444 T allele was 6.3% (16/252) in the CP group and 5.3% (12/226) in the control group (P > 0.5). There was no significant difference between groups in both allele frequencies (P > 0.5). The association of CRP + 1059G/C, CRP + 1444 C/T polymorphisms with CP was not found in a regression model (P > 0.5). The presence of a CRP + 1059C-allele was associated with lower serum CRP levels and the presence of a CRP + 1444T-allele was associated with higher serum CRP levels. However, the data suggested that CRP + 1059G/C, CRP + 1444 C/T polymorphisms were not significantly associated with serum CRP levels of chronic periodontitis patients in ethnic Han Chinese.

    Among the pregnancy urinary tract infections, asymptomatic bacteriuria (ASB) is the most common one. Untreated ASB can progress to pyelonephritis in 30-50% of the patients and can also result in prematurity in 27% of the pregnancy so it needs immediate diagnosis and treatment. In this study, we wanted to evaluate procalcitonin levels, compared to other inflammatory in pregnant women with ASB. The study was designed between the period of January 2012 and February 2013 at Sakarya University School of Medicine, Department of Gynecology and Obstetrics. The study population included 30 pregnant patients with asymptomatic bacteriuria and 39 healthy pregnant controls. Mean age was 28 (SD, 5.5) of the study population; mean maternal weight was 70 (SD, 8) kilogram. There were no statically significant differences between the groups according to the routine biochemical parameters, but gestational age was significantly lower in the ASB group compared to the controls (20.4 vs 28.6, respectively; p 0.05 ng/ml and 21(70%) patients had negative procalcitonin levels (Chi-squrae, p treatment of the first ASB diagnosis. Procalcitonin levels were significantly higher in ASB group than the control group and serum procalcitonin levels were higher in pregnant women with recurrent ASB. This finding is an important result revealed that high procalcitonin level can predict the further urinary tract infection risk. Finally, serum procalcitonin levels were normal in healthy pregnant women while other inflammatory markers such as WBC, ESR and CRP levels were higher.

    Overuse of antibiotics is a major public health problem, contributing to growing antibiotic resistance. Procalcitonin has been reported to be commonly elevated in bacterial, but not viral infection. Multiple European trials found procalcitonin-guided care reduced antibiotic use in lower respiratory tract infection, with no apparent harm. However, applicability to US practice is limited due to trial design features impractical in the US, between-country differences, and residual safety concerns. The Procalcitonin Antibiotic Consensus Trial (ProACT) is a multicenter randomized trial to determine the impact of a procalcitonin antibiotic prescribing guideline, implemented with basic reproducible strategies, in US patients with lower respiratory tract infection. We describe the trial methods using the Consolidated Standards of Reporting Trials (CONSORT) framework, and the rationale for key design decisions, including choice of eligibility criteria, choice of control arm, and approach to guideline implementation.

    Full Text Available A diagnosis of bronchiolitis is made clinically and the use of supportive laboratory examinations, including the quantification of C reactive protein (CRP, is not well established.The aim of this study was to evaluate the correlation between CRP value and indirect markers of disease severity in patients with bronchiolitis.This study included the patients diagnosed with bronchiolitis admitted to the Pediatrics Department of S. João Hospital in 2006. A retrospective review was made through analysing clinical files.176 patients aged 0 to 36 months (median of 4 months were included. 63.1% were males. CRP level was measured in 94.3% of the patients, with values ranging from zero to 256 mg/L and a median of 11 mg/L.CRP value in this population had a statistically significant relation with admission to Intensive Care Unit (ICU (p=0.008, length of hospital stay (p=0.025 and need for supplementary oxygen during hospital stay (p=0.022.This work raises the hypothesis that the CRP value on admission might be a marker of disease severity and have prognostic significance in patients with bronchiolitis. Further investigation is necessary to validate these results and exclude the potential confounding effect of associated infections.

    Highlights: Black-Right-Pointing-Pointer A new RIfS-based label-free biosensing system for C-reactive protein was developed. Black-Right-Pointing-Pointer Silicon-based inexpensive chips and the simple optical setup were employed. Black-Right-Pointing-Pointer Owing to the TMS treatment and the use of protein A, the sensitivity was enhanced. Black-Right-Pointing-Pointer It can be applied to other target as a substitute of SPR-based expensive sensors. - Abstract: Reflectometric interference spectroscopy (RIfS) is a label-free, time-resolved technique, and suitable for detecting antibody-antigen interaction. This work describes a continuous flow biosensor for C-reactive protein (CRP), involving an effective immobilization method of a monoclonal antibody against CRP (anti-CRP) to achieve highly sensitive RIfS-based detection of CRP. The silicon nitride-coated silicon chip (SiN chip) for the RIfS sensing was first treated with trimethylsilylchloride (TMS), followed by UV-light irradiation to in situ generation of homogeneous silanols on the surface. Following amination by 3-aminopropyltriethoxysilane, carboxymethyldextran (CMD) was grafted, and subsequently, protein A was immobilized to create the oriented anti-CRP surface. The immobilization process of protein A and anti-CRP was monitored with the RIfS system by consecutive injections of an amine coupling reagent, protein A and anti-CRP, respectively, to confirm the progress of each step in real time. The sensitivity was enhanced when all of the processes were adopted, suggesting that the oriented immobilization of anti-CRP via protein A that was coupled with the grafted CMD on the aminated surface of TMS-treated SiN chip. The feasibility of the present sensing system was demonstrated on the detection of CRP, where the silicon-based inexpensive chips and the simple optical setup were employed. It can be applied to other target molecules in various fields of life science as a substitute of surface plasmon resonance

    The aim of this study is to investigate the serum levels of procalcitonin and its association with autoantibodies in patients with euthyroid Hashimoto's thyroiditis. A total of 80 participants were included in the study; 40 of which were newly diagnosed with Hashimoto's thyroiditis, aged over 18, and 40 of which were healthy volunteers. The serum levels of procalcitonin were measured by enzyme-linked immunosorbent assay kit. Thyroid function tests were analyzed in hormone laboratory with Electro-chemiluminescence immunoassay. Hashimoto's thyroiditis patients had higher median procalcitonin levels than those of the control group (34.3 pg/mL vs 27.8 pg/mL respectively; P=.037). Also, male patients had higher median procalcitonin levels as compared to female patients (37 pg/mL vs 27 pg/mL respectively; P=.013). In the Hashimoto's thyroiditis group, procalcitonin level was positively correlated with anti-thyroglobulin and anti-thyroid peroxidase levels (r=.559, Pthyroid peroxidase levels were identified to be an independent predictor in diagnosis of Hashimoto's thyroiditis. The fact that procalcitonin was found to be correlated with thyroid autoantibodies and found to be an independent risk factor for Hashimoto's thyroiditis in the regression analysis in the framework of this study urges us to think that procalcitonin may be associated with the autoimmunity. © 2017 Wiley Periodicals, Inc.

    The possibility of side effects associated with the electromagnetic waves emitted from mobile phones is a controversial issue. The present study aimed to evaluate the effect of mobile phone use on parotid gland salivary concentrations of protein, amylase, lipase, immunoglobulin A, lysozyme, lactoferrin, peroxidase and C-reactive protein. Stimulated salivary samples were collected simultaneously from both parotid glands of 86 healthy volunteers. Salivary flow rate and salivary concentrations of proteins, amylase, lipase, lysozyme, lactoferrin, peroxidase, C-reactive protein and immunoglobulin A, were measured. Data were analysed using t-tests and one-way analyses of variance. Salivary flow rate and parotid gland salivary concentrations of protein were significantly higher on the right side compared to the left in those that predominantly held mobile phones on the right side. In addition, there was a decrease in concentrations of amylase, lipase, lysozyme, lactoferrin and peroxidase. The side of dominant mobile phone use was associated with differences in salivary flow rate and parotid gland salivary concentrations, in right-dominant users. Although mobile phone use influenced salivary composition, the relationship was not significant.

    C-reactive protein (CRP) is a pentameric protein that is present in the bloodstream during inflammatory events, e.g., liver failure, leukemia, and/or bacterial infection. The level of CRP indicates the progress and prognosis of certain diseases; it is therefore necessary to measure CRP levels in the blood accurately. The normal concentration of CRP is reported to be 1?3?mg/L. Inflammatory events increase the level of CRP by up to 500 times; accordingly, CRP is a biomarker of acute inflammator...

    We analyzed the effects of 1 year of engagement in ≥ 300 min/week of organized sports on inflammatory levels and vascular structure in adolescents. The sample was composed of 89 adolescents (11.6 ± 0.7 years old [43 boys and 46 girls]), stratified according to engagement in ≥ 300 min/week of sport practice during at least 12 months of follow-up (n = 15, sport practice; n = 74, non-sport practice). Arterial thickness (carotid and femoral) was assessed by ultrasound scan, while high sensitive C-reactive protein levels were used to assess inflammatory status. Trunk fatness (densitometry scanner), biological maturation (age at peak height velocity), blood pressure, and skipping breakfast were treated as covariates. Independently of body fatness and biological maturation, the group engaged in sports presented a higher reduction in C-reactive protein (mean difference -1.559 mg/L [95%CI -2.539 to -0.579]) than the non-sport group (mean difference -0.414 mg/L [95%CI -0.846 to 0.017]) (p = 0.040). There was a significant relationship between changes in C-reactive protein and changes in femoral intima-media thickness in the non-sport group (r = 0.311 [95%CI 0.026 to 0.549]). Inflammation decreased in adolescents engaged in organized sports, independently of trunk fatness and biological maturation. Moreover, inflammation was related to arterial thickening only in adolescents not engaged in sports. What is Known: • Intima media thickness is a relevant marker of cardiovascular disease in pediatric groups, being affected by obesity and inflammation. • The importance of monitoring inflammatory markers from childhood is enhanced by the fact that alterations in these inflammatory markers in early life predict inflammation and alterations in carotid IMT in adulthood. What is New: • Anti-inflammatory properties related to physical exercise performed at moderate intensity, on inflammation and alterations in IMT are not clear in pediatric

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

    C-reactive protein (CRP) interacts with phosphorylcholine (PC), Fcγ receptors, complement factor C1q and cell nuclear constituents, yet its biological roles are insufficiently understood. The aim was to characterize CRP-induced complement activation by ellipsometry. PC conjugated with keyhole limpet hemocyanin (PC-KLH) was immobilized to cross-linked fibrinogen. A low-CRP serum with different amounts of added CRP was exposed to the PC-surfaces. The total serum protein deposition was quantified and deposition of IgG, C1q, C3c, C4, factor H, and CRP detected with polyclonal antibodies. The binding of serum CRP to PC-KLH dose-dependently triggered activation of the classical pathway. Unexpectedly, the activation was efficiently down-regulated at CRP levels >150 mg/L. Using radial immunodiffusion, CRP-C1q interaction was observed in serum samples with high CRP concentrations. We propose that the underlying mechanism depends on fluid-phase interaction between C1q and CRP. This might constitute another level of complement regulation, which has implications for systemic lupus erythematosus where CRP is often low despite flare-ups

    Circulating C-reactive protein (CRP) levels are a marker of systemic inflammation and are associated with periodontal disease, a chronic bacterial infection associated with elevation of proinflammatory cytokines and prostaglandins. CRP has been associated with adverse pregnancy outcomes, including preterm delivery, preeclampsia, and intrauterine growth restriction. Furthermore, periodontal disease has been associated with increased risk of preterm low birth weight, low birth weight, and preterm birth. The present study was conducted to assess plasma CRP levels in pregnant women with and without periodontal disease; to evaluate the effect of periodontal therapy on the incidence of preterm delivery; and to compare the incidence of preterm delivery in pregnant women with and without periodontal disease. A total of 90 pregnant women aged between 18-35 years with gestational age between 12-28 weeks were recruited and divided into three equal groups (control group, study group, treatment group) of 30 each. Blood samples were taken for estimation of C-reactive protein levels from all groups at 12-20 weeks of gestation, determined using ultrasensitive turbidimetric immunoassay (QUANTIA-CRP US). The treatment group comprised plaque control, scaling, and root planning and daily rinsing with 0.2% chlorhexidine mouth before 28 weeks of gestation. The mean value of C-reactive protein levels in subjects with periodontal disease was higher compared to control group i.e., 1.20 +/- 0.247 mg/dl and 1.22 +/- 0.250 mg/dl, respectively, compared to 0.713 +/- 0.139 mg/ dl (P = 0.001). The mean value of CRP levels before treatment was greater than the mean value after treatment i.e., 1.22 +/- 0.25 compared to 0.84 +/- 0.189 (P periodontal disease group (study group) compared to 8.3% in the control group (P = 0.001). The incidence of preterm delivery in the treatment group was 15.0% compared to 31.7% in the nontreatment group (study group). The findings from the study suggest that

    C-reactive protein (CRP) is a well-known acute-phase reactant produced by the liver in response to inflammation caused by various stimuli. Periodontal disease is a chronic infection of tooth-supporting structures characterized by attachment loss and alveolar bone loss. The aim of this study was to assess the relationship between serum C-reactive protein levels and periodontal diseases. The study was conducted on 166 patients referring to Tabriz Faculty of Dentistry. The age range was between 35 and 59 years. 83 subjects with periodontitis according to NHANES III index as test group and 83 healthy individuals as controls participated in this study. Body mass index (BMI), waist circumference (WC), probing depth, attachment loss and CRP levels were measured in both test and control groups. Data was analyzed with Student's t-test, odds ratio (OR), Chi-square test and Spearman's correlation coefficient, using SPSS 13.0 software. The results revealed a statistically significant difference between all of the analyzed variables in test and control groups (P periodontitis and attachment loss (r = 0.662, P = 0.00). Excluding overweight, the association between all the variables was statistically significant (P periodontal disease is correlated with CRP elevation and dis-eases associated with obesity.

    Acromegaly is characterized by excess growth hormone and insulin-like growth factor-1 concentrations. There is conflicting evidence as to whether acromegaly is associated with an increased risk of atherosclerosis. Apelin is an adipose tissue-derived peptide that may be associated with hyperinsulinemia. Fetuin-A is a hepatocyte produced plasma glycoprotein that has an important role as a calcification inhibitor. The aim of this study was to examine apelin, fetuin-A, and procalcitonin concentrations and to assess their relationship with carotid intima medial thickness (cIMT) in subjects with acromegaly. Apelin, fetuin-A, and procalcitonin serum concentrations were measured in 37 (20 inactive and 17 active) subjects with acromegaly and 30 control subjects, along with carotid intima medial thickness. The concentrations of apelin, fetuin-A, and procalcitonin were increased in subjects with acromegaly. There were significant correlations between apelin, fetuin-A, and procalcitonin in subjects with acromegaly. Carotid intima medial thickness values were similar between control subjects and subjects with acromegaly. Carotid intima medial thickness was not increased in subjects with acromegaly. It is possible that the increased apelin and fetuin-A concentrations observed play a protective role against the development of atherosclerosis in subjects with acromegaly. © The Author(s) 2015 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

Blood samples were collected on admission, and days 1, and 3 to assess white blood cells (WBC, monocytes, C-reactive protein (CRP, procalcitonin (PCT, and copeptin. To determine the magnitude of association with the development of infections, odds ratios (OR were calculated for each prognostic blood marker. The discriminatory ability of different predictors was assessed, by calculating area under the receiver operating characteristic curves (AUC. Prognostic models including the three parameters with the best performance were identified.Of 383 patients, 66 (17.2% developed an infection after onset of stroke. WBC, CRP, copeptin and PCT were all independent predictors of any infection, pneumonia and UTI developed at least 24 hours after measurements. The combination of the biomarkers WBC, CRP and copeptin (AUC: 0.92 and WBC, CRP and PCT (AUC: 0.90 showed a better predictive accuracy concerning the development of pneumonia during hospitalization compared to each marker by itself (p-Wald <0.0001.Among ischemic stroke patients, copeptin, PCT, WBC and CRP measured on admission were predictors of infection in general, and specifically for pneumonia and UTI within 5 days after stroke. The combination of these biomarkers improved the prediction of patients who developed an infection.

    Full Text Available The Glasgow Prognostic Score (GPS is useful for predicting long-term mortality in cancer patients. Our aim was to validate the GPS in ED patients with different cancer-related urgency and investigate whether biomarkers would improve its accuracy. We followed consecutive medical patients presenting with a cancer-related medical urgency to a tertiary care hospital in Switzerland. Upon admission, we measured procalcitonin (PCT, white blood cell count, urea, 25-hydroxyvitamin D, corrected calcium, C-reactive protein, and albumin and calculated the GPS. Of 341 included patients (median age 68 years, 61% males, 81 (23.8% died within 30 days after admission. The GPS showed moderate prognostic accuracy (AUC 0.67 for mortality. Among the different biomarkers, PCT provided the highest prognostic accuracy (odds ratio 1.6 (95% confidence interval 1.3 to 1.9, P<0.001, AUC 0.69 and significantly improved the GPS to a combined AUC of 0.74 (P=0.007. Considering all investigated biomarkers, the AUC increased to 0.76 (P<0.001. The GPS performance was significantly improved by the addition of PCT and other biomarkers for risk stratification in ED cancer patients. The benefit of early risk stratification by the GPS in combination with biomarkers from different pathways should be investigated in further interventional trials.

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.

    Few studies have focused on the role of nutrition in periodontal disease. The purpose of this trial was to determine the effect of a nutritional supplement on gingival inflammation, bleeding, probing depth, clinical attachment level, carotenoid antioxidant level, and C-reactive protein. The test supplement, consisting of a standard multivitamin formula, as well as several phytonutrients associated with antiinflammatory/antioxidant effects, provided modest benefits in reducing inflammation; however, further studies with larger populations and longer intervention are warranted.

    Full Text Available Background/Purpose: Infection is the most common cause of death following burn injury. The study was conducted to compare the diagnostic value of serum procalcitonin (PCT with the other current benchmarks as early predictors of septic shock and bloodstream infection in burn patients. Methods: We included 24 patients admitted to the Burn Unit of a medical center from June 2015 to December 2015 from the Formosa Fun Coast dust explosion. We categorized all patients at initial admission into either sepsis or septic shock groups. Laboratory tests including the worst PCT and C-reactive protein (CRP levels, platelet (PLT, and white blood cell (WBC count were performed at <48 h after admission. Patients were also classified in two groups with subsequent bacteremia and non-bacteremia groups during hospitalization. Results: Significantly higher PCT levels were observed among participants with septic shock compared to those with sepsis (47.19 vs. 1.18 ng/mL, respectively; p < 0.001. Patients with bacteremia had significantly elevated PCT levels compared to patients without bacteremia (29.54 versus 1.81 ng/mL, respectively, p < 0.05. No significant differences were found in CRP levels, PLT, and WBC count between the two groups. PCT levels showed reasonable discriminative power (cut-off: 5.12 ng/mL; p = 0.01 in predicting of bloodstream infection in burn patients and the area under receiver operating curves was 0.92. Conclusions: PCT levels can be helpful in determining the septic shock and bloodstream infection in burn patients but CRP levels, PLT, and WBC count were of little diagnostic value.

  5. Novel Phosphorylation and Ubiquitination Sites Regulate Reactive Oxygen Species-dependent Degradation of Anti-apoptotic c-FLIP Protein*

    The cytosolic protein c-FLIP (cellular Fas-associated death domain-like interleukin 1β-converting enzyme inhibitory protein) is an inhibitor of death receptor-mediated apoptosis that is up-regulated in a variety of cancers, contributing to apoptosis resistance. Several compounds found to restore sensitivity of cancer cells to TRAIL, a TNF family death ligand with promising therapeutic potential, act by targeting c-FLIP ubiquitination and degradation by the proteasome. The generation of reactive oxygen species (ROS) has been implicated in c-FLIP protein degradation. However, the mechanism by which ROS post-transcriptionally regulate c-FLIP protein levels is not well understood. We show here that treatment of prostate cancer PPC-1 cells with the superoxide generators menadione, paraquat, or buthionine sulfoximine down-regulates c-FLIP long (c-FLIPL) protein levels, which is prevented by the proteasome inhibitor MG132. Furthermore, pretreatment of PPC-1 cells with a ROS scavenger prevented ubiquitination and loss of c-FLIPL protein induced by menadione or paraquat. We identified lysine 167 as a novel ubiquitination site of c-FLIPL important for ROS-dependent degradation. We also identified threonine 166 as a novel phosphorylation site and demonstrate that Thr-166 phosphorylation is required for ROS-induced Lys-167 ubiquitination. The mutation of either Thr-166 or Lys-167 was sufficient to stabilize c-FLIP protein levels in PPC-1, HEK293T, and HeLa cancer cells treated with menadione or paraquat. Accordingly, expression of c-FLIP T166A or K167R mutants protected cells from ROS-mediated sensitization to TRAIL-induced cell death. Our findings reveal novel ROS-dependent post-translational modifications of the c-FLIP protein that regulate its stability, thus impacting sensitivity of cancer cells to TRAIL. PMID:23519470

    Full Text Available Background and Objectives: Circulating C-reactive protein (CRP levels are a marker of systemic inflammation and are associated with periodontal disease, a chronic bacterial infection associated with elevation of proinflammatory cytokines and prostaglandins. CRP has been associated with adverse pregnancy outcomes, including preterm delivery, preeclampsia, and intrauterine growth restriction. Furthermore, periodontal disease has been associated with increased risk of preterm low birth weight, low birth weight, and preterm birth. The present study was conducted to assess plasma CRP levels in pregnant women with and without periodontal disease; to evaluate the effect of periodontal therapy on the incidence of preterm delivery; and to compare the incidence of preterm delivery in pregnant women with and without periodontal disease. Materials and Methods: A total of 90 pregnant women aged between 18-35 years with gestational age between 12-28 weeks were recruited and divided into three equal groups (control group, study group, treatment group of 30 each. Blood samples were taken for estimation of C-reactive protein levels from all groups at 12-20 weeks of gestation, determined using ultrasensitive turbidimetric immunoassay (QUANTIA-CRP US. The treatment group comprised plaque control, scaling, and root planning and daily rinsing with 0.2% chlorhexidine mouth before 28 weeks of gestation. Results: The mean value of C-reactive protein levels in subjects with periodontal disease was higher compared to control group i.e., 1.20 ± 0.247 mg/dl and 1.22 ± 0.250 mg/dl, respectively, compared to 0.713 ± 0.139 mg/ dl ( P = 0.001. The mean value of CRP levels before treatment was greater than the mean value after treatment i.e., 1.22 ± 0.25 compared to 0.84 ± 0.189 ( P < 0.001. The incidence of preterm delivery (< 37 weeks was 31.7% in the periodontal disease group (study group compared to 8.3% in the control group ( P = 0.001. The incidence of preterm

    2013-03-01

    There is evidence that neuropathic pain component in low back pain (LBP) patients is associated with higher ratings of comorbidities such as depression and anxiety disorders. In line with current findings, the purpose of this clinical study is to examine a hypothesis regarding a relationship of neuropathic pain component, depression, and other psychopathological symptoms in a specific group of LBP patients with sciatica pain. With respect to findings that depression is related to inflammatory changes, and inflammatory mediators may play a role in neuropathic pain generation, we have assessed also serum C-reactive protein (CRP). Results of the present study show that increased neuropathic pain component in sciatica patients is associated with elevated levels of depression, anxiety, alexithymia, and serum CRP levels. In conclusion, results of this study indicate that CRP levels in sciatica patients are closely associated with neuropathic pain.

    2018-04-01

    Full Text Available IntroductionC-reactive protein circulates as a pentameric protein (pCRP. pCRP is a well-established diagnostic marker as plasma levels rise in response to tissue injury and inflammation. We recently described pro-inflammatory properties of CRP, which are mediated by conformational changes from pCRP to bioactive isoforms expressing pro-inflammatory neo-epitopes [pCRP* and monomeric C-reactive protein (mCRP]. Here, we investigate the role of CRP isoforms in renal ischemia/reperfusion injury (IRI.MethodsRat kidneys in animals with and without intraperitoneally injected pCRP were subjected to IRI by the time of pCRP exposure and were subsequently analyzed for monocyte infiltration, caspase-3 expression, and tubular damage. Blood urea nitrogen (BUN was analyzed pre-ischemia and post-reperfusion. CRP effects on leukocyte recruitment were investigated via intravital imaging of rat-striated muscle IRI. Localized conformational CRP changes were analyzed by immunohistochemistry using conformation specific antibodies. 1,6-bis(phosphocholine-hexane (1,6-bisPC, which stabilizes CRP in its native pentameric form was used to validate CRP effects. Leukocyte activation was assessed by quantification of reactive oxygen species (ROS induction by CRP isoforms ex vivo and in vitro through electron spin resonance spectroscopy. Signaling pathways were analyzed by disrupting lipid rafts with nystatin and subsequent ROS detection. In order to confirm the translational relevance of our findings, biopsies of microsurgical human free tissue transfers before and after IRI were examined by immunofluorescence for CRP deposition and co-localization of CD68+ leukocytes.ResultsThe application of pCRP aggravates tissue damage in renal IRI. 1,6-bisPC reverses these effects via inhibition of the conformational change that leads to exposure of pro-inflammatory epitopes in CRP (pCRP* and mCRP. Structurally altered CRP induces leukocyte–endothelial interaction and induces ROS

    Elevations in C-reactive protein (CRP) concentration are associated with an increased risk of future coronary events in prospective studies and it has been suggested that CRP could be used to aid risk prediction. A +1444C>T polymorphism in the CRP gene has been associated with differences in CRP concentration. We investigated the effect of this polymorphism on the CRP response to periodontal therapy, an intermediate inflammatory stimulus. Clinical parameters, CRP, and interleukin-6 (IL-6) concentrations were evaluated in 55 consecutive patients suffering from periodontitis at baseline, 1, 7 and 30 days after an intensive course of periodontal treatment. In a multivariate analysis individuals homozygous for the +1444T allele showed higher CRP concentrations (day 1, 21.10+/-4.81 mg/L and day 7, 4.89+/-0.74 mg/L) compared with C-allele carriers (day 1, 12.37+/-1.61 mg/L and day 7, 3.08+/-2.00 mg/L). This effect was independent of conventional cardiovascular risk factors and inflammatory factors known to affect CRP concentrations. CRP genotype may need to be considered when CRP values are used in coronary risk prediction.

  18. Time-Resolved Fluorescence Immunoassay for C-Reactive Protein Using Colloidal Semiconducting Nanoparticles

    2011-11-01

    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.

    Few studies have investigated whether the Glasgow Prognostic Score (GPS), an inflammation-based prognostic score measured before resection of colorectal liver metastasis (CRLM), can predict postoperative survival. Sixty-three consecutive patients who underwent curative resection for CRLM were investigated. GPS was calculated on the basis of admission data as follows: patients with both an elevated C-reactive protein (>10 mg/l) and hypoalbuminemia (l) were allocated a GPS score of 2. Patients in whom only one of these biochemical abnormalities was present were allocated a GPS score of 1, and patients with a normal C-reactive protein and albumin were allocated a score of 0. Significant factors concerning survival were the number of liver metastases (p = 0.0044), carcinoembryonic antigen level (p = 0.0191), GPS (p = 0.0029), grade of liver metastasis (p = 0.0033), and the number of lymph node metastases around the primary cancer (p = 0.0087). Multivariate analysis showed the two independent prognostic variables: liver metastases > or =3 (relative risk 2.83) and GPS1/2 (relative risk 3.07). GPS measured before operation and the number of liver metastases may be used as novel predictors of postoperative outcomes in patients who underwent curative resection for CRLM. Copyright 2010 S.

    Sprint interval cycle training is a contemporary popular mode of training but its relative efficacy, under conditions of matched energy expenditure, to reduce risk factors for cardiometabolic disease is incompletely characterised, especially in young women. The purpose of this investigation was to determine the relative efficacy of six weeks of moderate-intensity cycling (MOD-C) and vigorous sprint-interval cycling (VIG-SIC) on lipid profile, insulin (INS) and insulin resistance using the homeostatic model assessment (HOMA-IR) and C-reactive protein (CRP) in inactive, overweight/obese (OW/OB) young women. Participants (BMI ≥25 kg/m 2 , waist circumference ≥88 cm) were randomly assigned to MOD-C (20-30 min at 60-70% of heart rate reserve(HRR)) or VIG-SIC (5-7 repeated bouts 30-second maximal effort sprints, followed by four minutes of active recovery) supervised training three days/week for six weeks, with each group matched on energy expenditure. Adiposity (%Fat) was measured using dual x-ray absorptiometry. Forty-four participants (20.4 ± 1.6 years, 65.9% Caucasian, 29.8 ± 4.1 kg/m 2 ) were included in the analysis. The improvement in CRP observed in the MOD-C group was larger than the VIG-C group (p = .034). Overall, high-density lipoprotein (HDL-C) and low-density lipoprotein (LDL-C) levels improved following training (p  .05). These results indicate MOD-C training may be more effective in reducing CRP than VIG-SIC.

    The aim of this study was to evaluate oxidative stress factors and C-reactive protein in the saliva of patients with oral lichen planus (OLP) and burning mouth syndrome (BMS). This consecutive, cross-sectional study included 20 patients with OLP, 19 with burning mouth syndrome (BMS), and 31 control subjects. The oral cavity of each patient was examined and patients responded to a quality of life questionnaire (OHIP-14) and the xerostomia inventory. The following parameters were measured in whole non-stimulated saliva: trolox equivalent antioxidant capacity (TEAC); total antioxidant capacity (TAC); cupric reducing antioxidant capacity (CUPRAC); ferric reducing ability of plasma (FRAP); C-reactive protein (CRP); nitric oxide; nitrates; and nitrites. The OLP group presented statistically significant differences in reactive oxygen species (ROS) (29 600 cps) in comparison with the control group (39 679 cps) (P < 0.05). In the BMS group, ROS was 29 707 cps with significant difference in comparison with the control group (P < 0.05). Significantly higher salivary nitric oxide (145.7 μmol) and nitrite (141.0 μmol) levels were found in OLP patients in comparison with control group (P < 0.05). Increases in nitric oxide and C-reactive protein were found in the saliva of OLP patients in comparison with BMS and control patients. Further studies are required to confirm these findings. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Inflammation is a common feature of both peripheral artery disease (PAD) and periodontal disease. The aim of this study is to evaluate the relationship between PAD and periodontal disease by examining the levels of inflammatory cytokines, pentraxin-3 (PTX-3), and high-sensitive C-reactive protein from serum. A total of 50 patients were included in this cross-sectional study. Patients were divided into two groups: those with PAD (test group) and those with the non-PAD group (control group) based on ankle-brachial index values. Periodontal examinations and biochemical analysis for PTX-3 and high-sensitive C-reactive protein were performed to compare the two groups. All the obtained data were sent for statistical analyses using SPSS version 18. In the clinical parameters, there is statistically significant difference present between plaque index, clinical attachment loss, and periodontal inflammatory surface area with higher mean values in patients with PAD having periodontitis. There is statistical significant ( P C-reactive protein (hs-CRP), and PTX-3. PTX-3 and acute-phase cytokine such as hs-CRP can be regarded as one of the best indicators to show the association between the PAD and periodontitis followed by hs-CRP, TC, very LDL (VLDL), and LDL. However, high-density lipoprotein (HDL) is a poor indicator for its association with chronic periodontitis and PAD.

    Full Text Available Background: Reactive arthritis (ReA is defined as a peripheral arthritis lasting longer than 1 month, associated with urethritis, cervicitis, or diarrhea. The reported annual incidence of ReA is approximately 30-40 cases per 100,000 adults, occurring commonly in the age group of 16 and 35 years. It is known to be associated with gastrointestinal infections with Shigella, Salmonella, and Campylobacter species and other microorganisms, as well as with genitourinary infections (especially with Chlamydia trachomatis. Case Report: This article reports the case of a 53-year-old, post-right total hip replacement, Indian man, with ReA, who presented with fever, respiratory distress, and abdominal discomfort. He complained of itching, tingling sensation, pain on urination, and retention of urine. He had right hip joint pain for 3 weeks, inability to move right leg since 10 days, and melena since 1 week. Laboratory tests revealed anemia, high liver and kidney function tests, elevated erythrocyte sedimentation rate, C reactive protein, procalcitonin and occult blood in stool. He tested positive for hepatitis C virus genotype 3. Gastroduodenoscopy revealed multiple apthoid ulcers at D2 and large gastric varix. Ultrasonography of whole abdomen revealed cholelithiasis and splenomegaly. Skin lesions and arthritis led to the diagnosis of associated ReA. The patient was managed conservatively and discharged in a stable condition. Conclusions: Our case is unlike classical ReA because the patient is older, HLA B27 negative, and without florid urethritis. Admitted for fever and lower urinary tract symptoms, along with respiratory distress, the primary objective of the emergency doctors was to prevent the patient from progressing to organ failure. The diagnosis of underlying atypical/incomplete ReA could easily have been missed without adequate awareness, dermatological consultation, and a skin biopsy.

    This study aims to determine the association of commonly used biochemical markers, such as albumin and C-reactive protein (CRP), with mortality and the prognostic performance of these markers combined with the pneumonia severity index (PSI) for mortality and adverse outcomes in patients with community-acquired pneumonia (CAP). The data were gathered prospectively for patients hospitalized with CAP via the emergency department. Laboratory values, including CRP and albumin, clinical variables, and the PSI were measured. Primary outcomes were 28-day mortality and survival times. Secondary outcome was admission to the intensive care unit, vasopressor use, or the need for mechanical ventilation during the hospital stay. A total of 424 patients were included. The 28-day mortality was 13.7%. C-reactive protein and albumin were significantly different between survivors and nonsurvivors. In logistic regression analysis, CRP and albumin were independently associated with 28-day mortality (P scale. The Cox proportional hazards analysis showed that high serum albumin (≥3.3 mg/dL) had a hazard ratio of 0.5 (95% confidence interval, 0.3-0.9), and high CRP (≥14.3 mg/dL) had a hazard ratio of 2.0 (95% confidence interval, 1.1-3.4). For predicting secondary outcome, adding albumin to PSI increased areas under the curve significantly, but CRP did not. Albumin and CRP were associated with 28-day mortality in hospitalized patients with CAP, and these markers increased prognostic performance when combined with the PSI scale. Crown Copyright © 2011.

    The aim of the present study was to investigate systemic levels of inflammatory markers of cardiovascular diseases like C-reactive protein and interleukin-6 in patients with chronic periodontitis, in comparison to periodontally healthy individuals. A total of 42 individuals, both males and females above the age of 30 years, were included in the study. Healthy controls (Group I, n = 14), chronic localized periodontitis (Group II, n = 14), and chronic generalized periodontitis (Group III, n = 14), all without any medical disorder, were recruited. Peripheral blood samples were taken and C-reactive protein (CRP) levels were estimated in the serum samples by using the Particle-Enhanced Turbidimetric Immunoassay (PETIA) technique. Serum samples of Interleukin-6 (IL-6) were assayed by using the Chemiluminescent Immunoassay (IMMULITE) technique. When mean CRP levels were compared between the groups, group III showed statistical significance when compared to group I (P = 0.04). Group III had a higher median IL-6 level (6.35 pg/mL) than Group II (Periodontitis results in higher systemic levels of CRP and IL-6. These elevated inflammatory factors may increase inflammatory activity in atherosclerotic lesions and potentially increasing the risk for cardiovascular events.

    Highlights: {center_dot} C-reactive protein has been determined in the concentration range 0.01-10 mg L{sup -1} using an electrochemiluminescence microchip which employs integrated electrodes with hydrophobic sample confinement. {center_dot} 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{sup -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.

    C-reactive protein (CRP) is used as a biomarker of morbidity and mortality risk in studies of population health, and is essential to interpretation of several micronutrient biomarkers. There is thus need for a robust high sensitivity CRP (hsCRP) measurement method for large-scale, non-clinical studies. We developed an efficient, inexpensive assay suitable for quantifying CRP across the physiological range using any blood specimen type. The ELISA uses readily available monoclonal antibodies to...

    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 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.

    This study assesses hormonal, inflammatory, and periodontal changes in pregnant women and postpartum in the absence of periodontal treatment, and seeks to determine any correlations among these parameters. A longitudinal, observational study of 117 pregnant women (aged 23 to 42 years) was undertaken in a private gynecologic center between weeks 32 and 35 of pregnancy and 6 to 8 weeks after delivery. Levels of progesterone and C-reactive protein (CRP) in plasma were determined, as well as periodontal indices, including: 1) plaque index (PI); 2) bleeding on probing (BOP); 3) probing depth (PD); and 4) clinical attachment level (CAL). Postpartum progesterone and CRP declined sharply from 90.85 ± 42.51 ng/mL and 3.73 ± 4.01 mg/L to 0.77 ± 1.43 ng/mL and 1.43 ± 1.67 mg/L, respectively. There was also a significant improvement in all periodontal indices (P 6 mm decreased significantly (P periodontal treatment. Decrease in CRP was related to an improvement in periodontal bleeding.

    The aim of this study was to evaluate the modifications of high sensitivity C-reactive protein (CRP) with antihypertensive and statin treatment in a hypertensive population with a wide range of coronary risks (CR). Retrospective follow-up study in 665 hypertensive patients: 556 (52% male) without dyslipidemia and CR (Framingham at 10 years) of 8.3 (7.6) as a control group (C) and 109 (61% male) with dyslipidemia and CR of 13.1 (8.8) who were treated with statins (T). Statins treatment was established according to NCEP-ATP-III. In both groups, the antihypertensive treatment was optimized in order to achieve blood pressure (BP) control (< 140/90 mmHg). A lipid profile and high sensitivity CRP (analyzed by nephelometry) was performed at the beginning and at the end of follow up [14.3 (3.6) months]. CRP levels were reduced in the T group -0.17 (0.2) mg/L vs. 0.14 (0.09) mg/L (p = 0.003, Mann-Whitney) in C. The lessening of CRP was not related to the reduction of lipids levels: total cholesterol (r = 0.06; p = 0.49), LDL-C (r = 0.11; p = 0.24), triglycerides (r = -0.02; p = 0.81) (Spearman), or to the reduction of systolic BP (r = -0.07; p = 0.44) and diastolic BP (r = -0.121; p = 0.21). The T group was treated with more antihypertensive drugs than C (2.2 [2.3] vs. 2.5 [1.2]; p = 0.02). Patients treated with ECA inhibitors or angiotensin II antagonist showed a tendency to decreasing the CRP levels more (p = 0.08). In hypertensive populations, statins induce a reduction of CRP levels. The reduction is not related to the lowering of lipids levels or BP values. The effect of statins on the reduction of CRP in hypertensive patients is not related to the lowering of lipids or BP.

    2014-01-01

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

    To assess whether different diagnostic and prognostic cutoff values of procalcitonin should be considered in surgical and in medical patients with septic shock. Prospective observational study. Intensive care unit of the Avicenne teaching hospital, France. All patients with septic shock or noninfectious systemic inflammatory response syndrome within 48 hrs after admission. None. Patients were allocated to one of the following groups: group 1 (surgical patients with septic shock), group 2 (surgical patients with noninfectious systemic inflammatory response syndrome), group 3 (medical patients with septic shock), and group 4 (medical patients with noninfectious systemic inflammatory response syndrome). Procalcitonin at study entry was compared between group 1 and group 2 and between group 3 and group 4 to determine the diagnostic cutoff value in surgical and in medical patients, respectively. Procalcitonin was compared between survivors and nonsurvivors from group 1 and group 3 to determine its prognostic cutoff value. One hundred forty-three patients were included: 31 in group 1, 36 in group 2, 36 in group 3, and 40 in group 4. Median procalcitonin levels (ng/mL [interquartile range]) were higher in group 1 than in group 3 (34.00 [7.10-76.00] vs. 8.40 [3.63-24.70], p = .01). In surgical patients, the best diagnostic cutoff value was 9.70 ng/mL, with 91.7% sensitivity and 74.2% specificity. In medical patients, the best diagnostic cutoff value was 1.00 ng/mL, with 80% sensitivity and 94% specificity. Procalcitonin was a reliable early prognostic marker in medical but not in surgical patients with septic shock. A cutoff value of 6.00 ng/mL had 76% sensitivity and 72.7% specificity for separating survivors from nonsurvivors. The diagnostic cutoff value of procalcitonin was higher in surgical than in medical patients. Early procalcitonin was of prognostic interest in medical patients.

    Sera from patients with periodontal infections contain elevated levels of C-reactive protein (CRP) compared to periodontally healthy individuals. Most studies to date have included patients with chronic periodontitis, and few investigators have studied CRP levels in subjects with aggressive periodontitis (AgP). The purpose of this study was to determine the relative levels of serum CRP in AgP patients and periodontally healthy subjects and to examine patients' characteristics that might account for intergroup differences. Serum samples were collected from 93 patients with generalized AgP (GAgP), from 97 patients with localized AgP (LAgP), and from 91 healthy controls (non-periodontitis [NP]). Periodontal examination consisted of plaque index, gingival index, probing depth, bleeding index, and attachment loss measurements. Current smoking was assessed by determination of serum cotinine levels by enzyme-linked immunosorbent assay (ELISA), and serum CRP levels were determined using a high-sensitivity ELISA assay. The three groups were significantly different from one another (P periodontal and demographic variables and current smoking, both mean probing depth and periodontal diagnosis remained correlated with CRP levels. Patients with AgP have statistically significant elevations in serum CRP levels compared to subjects without periodontitis. Elevated CRP in these subjects might represent a contribution of periodontal infections to systemic inflammation in relatively young individuals.

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

    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 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 provide

    Full Text Available Challenges in the differentiation of the aetiology of acute exacerbations of chronic obstructive pulmonary disease (AECOPD have led to significant overuse of antibiotics. Serum procalcitonin, released in response to bacterial infections, but not viral infections, could possibly identify AECOPD requiring antibiotics. In this meta-analysis we assessed the clinical effectiveness of procalcitonin-based protocols to initiate or discontinue antibiotics in patients presenting with AECOPD. Based on a prospectively registered protocol, we reviewed the literature and selected randomised or quasi-randomised trials comparing procalcitonin-based protocols to initiate or discontinue antibiotics versus standard care in AECOPD. We followed Cochrane and GRADE (Grading of Recommendations, Assessment, Development and Evaluation guidance to assess risk of bias, quality of evidence and to perform meta-analyses. We included eight trials evaluating 1062 patients with AECOPD. Procalcitonin-based protocols decreased antibiotic prescription (relative risk (RR 0.56, 95% CI 0.43–0.73 and total antibiotic exposure (mean difference (MD −3.83, 95% CI (−4.32–−3.35, without affecting clinical outcomes such as rate of treatment failure (RR 0.81, 0.62–1.06, length of hospitalisation (MD −0.76, −1.95–0.43, exacerbation recurrence rate (RR 0.96, 0.69–1.35 or mortality (RR 0.99, 0.58–1.69. However, the quality of the available evidence is low to moderate, because of methodological limitations and small overall study population. Procalcitonin-based protocols appear to be clinically effective; however, confirmatory trials with rigorous methodology are required.

    Procalcitonin has been advocated as a specific biomarker for bacterial infection. We performed this study to determine whether accuracy of procalcitonin for diagnosis of postoperative bacterial infection is affected by renal function after aortic surgery. Single-center prospective study. University hospital. Two hundred seventy-six patients scheduled for elective major aortic surgery. Blood samples were taken before surgery and each day over the 5-day postoperative period, and measurement of serum procalcitonin was performed. Diagnosis of infection was performed by a blinded expert panel. Renal function was assessed using an estimate of creatinine clearance with the Cockcroft formulas. Renal dysfunction was defined as a creatinine clearance <50 mL x min(-1). Infection was diagnosed in 67 patients. Seventy five patients (27%) had postoperative renal dysfunction. Procalcitonin was significantly higher in infected patients, with a peak reached at the fourth postoperative day, but it was significantly higher in patients with impaired renal function in both control and infected patients. The optimal threshold of procalcitonin markedly differed in patients with renal dysfunction compared with patients without renal dysfunction (2.57 vs. 0.80 ng x mL(-1), p < .05). The diagnostic accuracy of procalcitonin significantly increased (0.74 vs. 0.70, p < .05) when the threshold of procalcitonin was adapted to the renal function. The elevation of procalcitonin occurred 2 days before the medical team was able to diagnose infection. Procalcitonin is a valuable marker of bacterial infections after major aortic surgery, but renal function is a major determinant of procalcitonin levels and thus different thresholds should be applied according to renal function impairment.

    The prevalence of obesity is increasing in dogs as well as in humans. C-reactive protein (CRP) is an important tool for the detection of inflammation and/or early tissue damage and is linked to obesity in humans. The objective of the present study was to determine if serum CRP levels are altered in obese dogs. Fifteen lean (control group) and 16 overweight (obese group) dogs were examined. Blood samples were collected under fasted conditions for serum determination of CRP, glucose, insulin, cholesterol, triglyceride, and fructosamine. Results indicated that obese dogs were insulin resistant because serum insulin and insulin/glucose ratios were higher than in lean dogs (P obese dogs than in controls (P obese group compared with the control group. Based on these results, it can be postulated that CRP production is inhibited by obesity and insulin resistance in dogs.

    Fibromyalgia, a potentially debilitating chronic pain syndrome of unknown etiology, may be characterized by inflammation. In this study, we investigated the relation of FMS to serum C-reactive protein (CRP) in a large population of adults (18+) and investigated the influence of other factors on this relationship, including BMI, comorbidities, as well as mood and sleep disturbance. Participants were 52,535 Ohio Valley residents (Fibromyalgia n = 1125). All participants completed a comprehensive health survey (2005-2006) part of the C8 Health Project; serum levels of CRP were obtained, as was history of Fibromyalgia physician diagnosis. Logistic and linear regressions were used for this cross-sectional analysis. Mean CRP was higher among participants reporting Fibromyalgia than those without (5.54 ± 9.8 vs.3.75 ± 7.2 mg/L, p BMI) and comorbidities to the model markedly weakened this relationship (AORs, respectively, for highest vs lowest CRP quartile = 1.2 (CI 1.0,1.4) and 1.1 (CI 0.9,1.3). In contrast, inclusion of mood and sleep impairment only modestly reduced the adjusted risk estimate (AORs for highest vs. lowest quartile = 1.3 (CI 1.1,1.5) for each)). Findings from this large cross-sectional study indicate a significant positive cross-sectional association of Fibromyalgia to serum C-reactive protein may be explained, in part, by BMI and comorbidity. Prospective research is needed to confirm this, and clarify the potential mediating influence of obesity and comorbid conditions on this relationship.

    Results of previous studies have shown that repeated abdominopelvic computed tomography (CT) examinations can lead to substantial cumulative diagnostic radiation exposure in patients with Crohn\\'s disease (CD). Improved selection of patients referred for CT will reduce unnecessary radiation exposure. This study examines if serum C-reactive protein (CRP) concentration predicts which symptomatic patients with CD are likely to have significant disease activity or disease complications (such as abscess) detected on abdominopelvic CT.

    C-reactive protein concentration has continuous associations with risk of coronary artery disease, ischemic stroke and death from several cancers. In addition, several studies have shown that CRP could be used to predict first ever myocardial infarction and stroke in healthy subjects, as well as outcome in acute setting. High levels of another biomarker, D-dimer, have been found to be independently associated with occurrence of coronary events. Methods: This correlational study was carried out at the Department of Cardiology, Ayub Teaching Hospital Abbottabad, in collaboration with the department of Biochemistry Postgraduate Medical Institute Lahore from 15th July 2013 to 15th May 2014. Patients aged 30 years or more of either gender having coronary artery disease was included in the study. Their serum D-dimer levels and C-reactive protein levels were measured for correlation with coronary artery disease. Results: A total of 50 patients of CAD were included in this study. Out of these 30 (60 percent) were males and 20 (40 percent) were females. Elevated CRP levels and D-dimer levels were noted in all of these patients. Pearson correlation coefficient test was performed on both CRP and D-dimer levels. Pearson correlation coefficient was calculated to be r= -0.1522 and when a p value was calculated, it was found to be 0.292 which implied that the results were not significant. Conclusion: This study showed that there is no correlation between CRP levels and D-dimer levels in patients with Coronary Artery Disease. (author)

    2011-04-01

    The results of several cross-sectional studies suggested a relationship between periodontitis and higher serum levels of C-reactive protein (CRP). Most of these studies were restricted to adult study groups with severe periodontal inflammation, and the potential effects of confounding factors were frequently overlooked. A case-referent study comprised of 87 adolescent cases who presented with clinical attachment loss ≥3 mm recorded in ≥2 of 16 teeth and 73 controls who did not fulfill these criteria was nested in a fully enumerated adolescent population. Venous blood samples were obtained, and CRP levels were quantified, using a high-sensitive bead-based flow cytometric assay. The Mann-Whitney U test was used to assess overall differences between groups. The median serum CRP values for cases and controls were 64 ng/ml (interquartile range: 27 to 234 ng/ml) and 55 ng/ml (31 to 183 ng/ml), respectively (P = 0.8). Serum levels of CRP were not significantly higher among subjects with periodontitis than among controls. However, a statistically significant positive association between percentages of sites with bleeding on probing and log-transformed CRP values was observed.

    Full Text Available Background. Early recognition of bacterial infection and antibiotic treatment are very important in critically ill patients. Procalcitonin (PCT is a marker of bacterial infections accompanied by systemic inflammatory response. Higher values were also noticed with parasitical and fungal infections, but PCT is normal in viral and systemic diseases. The aim of this study was to assess whether PCT is better marker for bacterial infections than C-reactive protein (CRP and if they have a prognostic value.Methods. 34 patients were included into our retrospective study. All of them had clinical or laboratory signs of infection at the first PCT determination. We measured PCT, CRP, erythrocyte sedimentation rate (SR and leukocyte count. On the base of microbiological results we divided patients into three groups. Group A had patients with sterile cultures, group B included the ones with negative blood cultures, but from other cultures causative agents were identified. The patients in group C had positive blood cultures. Retrospectively we studied PCT and CRP values among groups and among survivors and non survivors.Results. An average median value of PCT in group A was 8.9 ± 13.3 ng/ml, in group B 5.3 ± 9.3 ng/ml and in group C 21.0 ± 25.0 ng/ml. In group B, the average median value of PCT was significantly higher than in group C (p = 0.019, but that was not the case in group A (p = 0.23. The average median values of CRP were 129.9 ± 67.4 mg/l in group A, 104.3 ± 60.1 mg/l in group B and 117.4 ± 46.1 mg/l in group C. Between groups, differences of CRP values were not statistically significant. The average initial value of PCT in group of non survivors (8.9 ± 49 was not significantly higher then in group of survivors (3.14 ± 55.4 (p = 0.48. The average final value was significantly higher (p = 0.0013 in group of non survivors (13.1 ± 23.9 ng/l than in group of survivors (0.55 ± 7.3 ng/ml. In both groups the average initial values of CRP did not

    Abstract Migraine is a highly prevalent and frequently disabling disorder. Since the pathogenesis of this condition has a strong inflammatory component and migraine is significantly associated with cardiovascular disease, we assess whether C-reactive protein (CRP) may be epidemiologically or casually linked with migraine. An electronic search on Medline, Scopus and Web of Science produced 17 studies reporting original data about the epidemiological association between CRP and migraine (1 retrospective, 1 interventional, 14 cross-sectional and 1 both interventional and cross-sectional). When all studies reporting sufficient data about CRP values were pooled (n=12; 6980 cases and 38,975 controls), the concentration of CRP was found to be significantly higher in patients with migraine than in controls (weighted mean difference 1.12 mg/L; 95% CI 1.01-1.25 mg/L; p<0.001). In further analysis of studies containing separate data for migraine with and without aura (n=7), CRP values remained significantly higher in both migraineur patients with aura (n=1939; weighted mean difference 0.88 mg/L; 95% CI 0.63-1.14 mg/L; p<0.001) or without aura (n=2483; weighted mean difference 1.04 mg/L; 95% CI 0.78-1.30 mg/L; p<0.001) when compared with controls (n=29,354). Despite a large inter-study heterogeneity (99.3%), our analysis provides evidence of a potential epidemiological association between increased concentration of CRP and migraine, thus paving the way for further clinical investigations about therapeutic agents that may contextually decrease the risk of cardiovascular disease and reduce the burden of migraine.

    Bansal, Tushika; Pandey, Anita; D, Deepa; Asthana, Ashish K

    2014-07-01

    Periodontal disease is a chronic infection of the gums characterised by a loss of attachment between the tooth and bone, and bone loss. C-reactive protein (CRP) elevation is a part of the acute phase response to acute and chronic inflammation. Many epidemiological studies have shown that serum CRP levels were elevated in patients with chronic periodontitis. CRP levels increase to hundreds of μg/ml within hours following infection. It out-performs erythrocyte sedimentation rate (ESR) in terms of responsiveness and specificity for inflammation. While CRP elevation is suggestive of inflammation or infection in the appropriate clinical context, it can also occur with obesity and renal dysfunction. Conversely, a lack of CRP elevation in inflammation may be seen with hepatic failure, as well as during flares of conditions such as systemic lupus erythematosus.

    C-reactive protein (CRP), the classic acute-phase protein, plays an important role in the etiology of myocardial infarction (MI). Emerging evidence has shown that the common polymorphisms in the CRP gene may influence an individual's susceptibility to MI; but individually published studies showed inconclusive results. This meta-analysis aimed to derive a more precise estimation of the associations between CRP gene polymorphisms and MI risk. A literature search of PubMed, Embase, Web of Science, and China BioMedicine (CBM) databases was conducted on articles published before June 1st, 2013. Crude odds ratio (OR) with 95% confidence interval (CI) were calculated. Nine case-control studies were included with a total of 2992 MI patients and 4711 healthy controls. The meta-analysis results indicated that CRP rs3093059 (T>C) polymorphism was associated with decreased risk of MI, especially among Asian populations. However, similar associations were not observed in CRP rs1800947 (G>C) and rs2794521 (G>A) polymorphisms (all p>0.05) among both Asian and Caucasian populations. Univariate and multivariate meta-regression analyses showed that ethnicity may be a major source of heterogeneity. No publication bias was detected in this meta-analysis. In conclusion, the current meta-analysis indicates that CRP rs3093059 (T>C) polymorphism may be associated with decreased risk of MI, especially among Asian populations.

    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

The main aim of this study was to examine the association between supportive, aversive, and ambivalent family/friends with levels of C-reactive proteins. Three hundred participants from the North Texas Heart Study completed the social relationships index and a blood draw to assess high-sensitivity C-reactive proteins (hs-CRPs). After standard controls, the number of supportive family members predicted lower hs-CRP levels, whereas the number of ambivalent family members predicted higher hs-CRP levels. These links were independent of depressive symptoms and perceived stress. These data highlight the importance of considering specific types of relationships and their underlying positive and negative aspects in research on social ties and physical health.

    Background: The acute-phase protein C-reactive protein (CRP) is used as a diagnostic and prognostic marker in humans with various neoplasias, including non-Hodgkin's lymphoma. Objective: To evaluate if CRP could be used to detect different remission states in dogs with lymphoma. Animals: Twenty......-two dogs with untreated multicentric lymphoma. Methods: Prospective observational study. Blood samples were collected at the time of diagnosis, before each chemotherapy session, and at follow-up visits, resulting in 287 serum samples. Results: Before therapy, a statistically significant majority...... of the dogs (P = .0019) had CRP concentrations above the reference range (68%, 15/22). After achieving complete remission 90% (18/20) of the dogs had CRP concentrations within the reference range, and the difference in values before and after treatment was statistically significant (P

    Early and adequate treatment of ventilator-associated pneumonia (VAP) is mandatory to improve the outcome. The aim of this study was to evaluate, in medical ICU patients, the respective and combined impact of the Clinical Pulmonary Infection Score (CPIS), broncho-alveolar lavage (BAL) gram staining, endotracheal aspirate and a biomarker (procalcitonin) for the early diagnosis of VAP. Prospective, observational study A medical intensive care unit in a teaching hospital. Over an 8-month period, we prospectively included 57 patients suspected of having 86 episodes of VAP. The day of suspicion, a BAL as well as alveolar and serum procalcitonin determinations and evaluation of CPIS were performed. Of 86 BAL performed, 48 were considered positive (cutoff of 10(4) cfu ml(-1)). We found no differences in alveolar or serum procalcitonin between VAP and non-VAP patients. Including procalcitonin in the CPIS score did not increase its accuracy (55%) for the diagnosis of VAP. The best tests to predict VAP were modified CPIS (threshold at 6) combined with microbiological data. Indeed, both routinely twice weekly performed endotracheal aspiration at a threshold of 10(5) cfu ml(-1) and BAL gram staining improved pre-test diagnostic accuracy of VAP (77 and 66%, respectively). This study showed that alveolar procalcitonin performed by BAL does not help the clinician to identify VAP. It confirmed that serum procalcitonin is not an accurate marker of VAP. In contrast, microbiological resources available at the time of VAP suspicion (BAL gram staining, last available endotracheal aspirate) combined or not with CPIS are helpful in distinguishing VAP diagnosed by BAL from patients with a negative BAL.

    Measurements of protein-conjugated acrolein (PC-Acro), IL-6, and C-reactive protein (CRP) in plasma were useful for identifying silent brain infarction with high sensitivity and specificity. The aim of this study was to determine whether acrolein causes increased production of IL-6 and CRP in thrombosis model mice and cultured cells. In mice with photochemically induced thrombosis, acrolein produced at the locus of infarction increased the level of IL-6 and then CRP in plasma. This was confirmed in cell culture systems - acrolein stimulated the production of IL-6 in mouse neuroblastoma Neuro-2a cells, mouse macrophage-like J774.1 cells, and human umbilical vein endothelial cells (HUVEC), and IL-6 in turn stimulated the production of CRP in human hepatocarcinoma cells. The level of IL-6 mRNA was increased by acrolein through an increase in phosphorylation of the transcription factors, c-Jun, and NF-κB p65. Furthermore, CRP stimulated IL-6 production in mouse macrophage-like J774.1 cells and HUVEC. IL-6 functioned as a protective factor against acrolein toxicity in Neuro-2a cells and HUVEC. These results show that acrolein stimulates the synthesis of IL-6 and CRP, which function as protecting factors against acrolein toxicity, and that the combined measurement of PC-Acro, IL-6, and CRP is effective for identification of silent brain infarction. The combined measurements of protein-conjugated acrolein (PC-Acro), IL-6, and C-reactive protein (CRP) in plasma were useful for identifying silent brain infarction. The aim of this study was to determine whether acrolein causes increased production of IL-6 and CRP, and indeed acrolein increased IL-6 synthesis and IL-6 in turn increased CRP synthesis. Furthermore, IL-6 decreased acrolein toxicity in several cell lines. © 2013 International Society for Neurochemistry.

    This study evaluates potential markers in blood and stools for their ability to distinguish bacterial from viral gastroenteritis. A total of 108 patients were prospectively recruited, of which 27 showed bacterial, 30 viral, and 51 no detectable pathogen, respectively. Cytokines, C-reactive protein (CRP), and white blood cells as well as the 2 fecal markers lactoferrin and calprotectin were determined. Statistics comprised Kruskal-Wallis test and U test in addition to an assessment of receiver operating characteristic. Interferon γ (IFNγ) levels were significantly increased in the viral group compared to the bacterial and nonspecific group. For the bacterial group, both fecal markers lactoferrin and calprotectin as well as CRP were significantly higher in comparison to the other 2 groups. To differentiate between bacterial and viral gastroenteritis, CRP, serum IFNγ, and the fecal proteins lactoferrin and calprotectin may be useful. A corresponding algorithm should be evaluated prospectively. Copyright © 2013 Elsevier Inc. All rights reserved.

    2015-01-01

    Background: Despite the high levels of inflammation in hemodialysis patients and the effects of diet on systemic inflammation, such as the development of atherosclerosis and cardiovascular disease, few studies have evaluated the relationship of macronutrients and antioxidants intake with serum C-reactive protein (CRP). Therefore, this study assessed the relationship between serum high sensitivity CRP (hs-CRP) with macronutrients and antioxidants intake and serum albumin. Methods: This cross-sectional study used census sampling to select 75 hemodialysis patients (35 men and 40 women) who attended the hemodialysis department of Vaseie Hospital of Sabzevar, Iran. After obtaining the written consent, all the patients were interviewed and dietary data was collected by using a semi-quantitative food frequency questionnaire including 160 food items. Diet analysis was performed with Nutritionist IV. Before being connected to the dialysis machine, 5 cc fasting blood samples were obtained from all participants and serum hs-CRP and albumin levels were measured. All the statistical analyses were conducted with SPSS -for Windows, version 16.0. Results: The patients' mean body mass index was 20.09 ± 3.27 kg/ m2. The participants' intake of antioxidants and all macronutrients, except for carbohydrates and proteins, was less than the standard levels. Moreover, the hs-CRP had significant inverse relationships with serum albumin (P=0.0001) and vitamin E and C intakes but was not significant. Also, a significant relationship was observed between hs-CRP levels and the intake of energy (P=0.002) and protein (P=0.0001). Conclusion: Our findings indicated hs-CRP levels of hemodialysis patients to have significant inverse relationships with serum albumin and vitamin E and C intakes but was not significant. Also, a significant relationship was observed between hs-CRP levels and the intake of energy and protein.

    The semi-quantitative serum procalcitonin test (Brahms PCT-Q) is available conveniently in clinical practice. However, there are few data on the relationship between results for this semi-quantitative procalcitonin test and clinical outcomes of community-acquired pneumonia (CAP). We investigated the usefulness of this procalcitonin test for predicting the clinical outcomes of CAP in comparison with severity scoring systems and the blood urea nitrogen/serum albumin (B/A) ratio, which has been reported to be a simple but reliable prognostic indicator in our prior CAP study. This retrospective study included data from subjects who were hospitalized for CAP from August 2010 through October 2012 and who were administered the semi-quantitative serum procalcitonin test on admission. The demographic characteristics; laboratory biomarkers; microbiological test results; Pneumonia Severity Index scores; confusion, urea nitrogen, breathing frequency, blood pressure, ≥ 65 years of age (CURB-65) scale scores; and age, dehydration, respiratory failure, orientation disturbance, pressure (A-DROP) scale scores on hospital admission were retrieved from their medical charts. The outcomes were mortality within 28 days of hospital admission and the need for intensive care. Of the 213 subjects with CAP who were enrolled in the study, 20 died within 28 days of hospital admission, and 32 required intensive care. Mortality did not differ significantly among subjects with different semi-quantitative serum procalcitonin levels; however, subjects with serum procalcitonin levels ≥ 10.0 ng/mL were more likely to require intensive care than those with lower levels (P pneumonia. Using the receiver operating characteristic curves for mortality, the area under the curve was 0.86 for Pneumonia Severity Index class, 0.81 for B/A ratio, 0.81 for A-DROP, 0.80 for CURB-65, and 0.57 for semi-quantitative procalcitonin test. The semi-quantitative serum procalcitonin level on hospital admission was less

    An accurate and highly sensitive sensor platform has been demonstrated for the detection of C-reactive protein (CRP) using optical fiber Bragg gratings (FBGs). The CRP detection has been carried out by monitoring the shift in Bragg wavelength (ΔλB) of an etched FBG (eFBG) coated with an anti-CRP antibody (aCRP)-graphene oxide (GO) complex. The complex is characterized by Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy and atomic force microscopy. A limit of detection of 0.01mg/L has been achieved with a linear range of detection from 0.01mg/L to 100mg/L which includes clinical range of CRP. The eFBG sensor coated with only aCRP (without GO) show much less sensitivity than that of aCRP-GO complex coated eFBG. The eFBG sensors show high specificity to CRP even in the presence of other interfering factors such as urea, creatinine and glucose. The affinity constant of ∼1.1×10(10)M(-1) has been extracted from the data of normalized shift (ΔλB/λB) as a function of CRP concentration. Copyright © 2014 Elsevier B.V. All rights reserved.

    The goal of this study was to investigate the association of physical activity (PA) and cardiorespiratory fitness with C-reactive protein (CRP) concentration in adolescents. The sample included 386 Portuguese adolescents (n = 207, female), age 12-18 years, assessed in the year 2012. The PA was assessed with the use of accelerometers, and the cardiorespiratory fitness was assessed by the Fitnessgram Pacer test. Blood samples were collected after a 10-hour fasting, and high-sensitivity PCR concentration was further assessed. Significant associations between CRP and cardiorespiratory fitness were found for females (r = -0.313; p genders. Therefore, CRP is apparently negatively associated with cardiorespiratory fitness, with differences between males and females; for females it seems less dependent than BMI.

    Full Text Available Abstract Background A Paleolithic diet has been suggested to be more in concordance with human evolutionary legacy than a cereal based diet. This might explain the lower incidence among hunter-gatherers of diseases of affluence such as type 2 diabetes, obesity and cardiovascular disease. The aim of this study was to experimentally study the long-term effect of a Paleolithic diet on risk factors for these diseases in domestic pigs. We examined glucose tolerance, post-challenge insulin response, plasma C-reactive protein and blood pressure after 15 months on Paleolithic diet in comparison with a cereal based swine feed. Methods Upon weaning twenty-four piglets were randomly allocated either to cereal based swine feed (Cereal group or cereal free Paleolithic diet consisting of vegetables, fruit, meat and a small amount of tubers (Paleolithic group. At 17 months of age an intravenous glucose tolerance test was performed and pancreas specimens were collected for immunohistochemistry. Group comparisons of continuous variables were made by use of the t-test. P Results At the end of the study the Paleolithic group weighed 22% less and had 43% lower subcutaneous fat thickness at mid sternum. No significant difference was seen in fasting glucose between groups. Dynamic insulin sensitivity was significantly higher (p = 0.004 and the insulin response was significantly lower in the Paleolithic group (p = 0.001. The geometric mean of C-reactive protein was 82% lower (p = 0.0007 and intra-arterial diastolic blood pressure was 13% lower in the Paleolithic group (p = 0.007. In evaluations of multivariate correlations, diet emerged as the strongest explanatory variable for the variations in dynamic insulin sensitivity, insulin response, C-reactive protein and diastolic blood pressure when compared to other relevant variables such as weight and subcutaneous fat thickness at mid sternum. There was no obvious immunohistochemical difference in pancreatic islets

    Metabolism of the hepatotoxicant furan leads to protein adduct formation in the target organ. The initial bioactivation step involves cytochrome P450-catalyzed oxidation of furan, generating cis-2-butene-1,4-dial (BDA). BDA reacts with lysine to form pyrrolin-2-one adducts. Metabolic studies indicate that BDA also reacts with glutathione (GSH) to generate 2-(S-glutathionyl)butanedial (GSH-BDA), which then reacts with lysine to form GSH-BDA-lysine cross-links. To explore the relative reactivity of these two reactive intermediates, cytochrome c was reacted with BDA in the presence and absence of GSH. As judged by MALDI-TOF mass spectrometry, BDA reacts extensively with cytochrome c to form adducts that add 66 Da to the protein, consistent with the formation of pyrrolinone adducts. Addition of GSH to the reaction mixture reduced the overall extent of adduct formation. The mass of the adducted protein was shifted by 355 Da as expected for GSH-BDA-protein cross-link formation. LC-MS/MS analysis of the tryptic digests of the alkylated protein indicated that the majority of adducts occurred on lysine residues, with BDA reacting less selectively than GSH-BDA. Both types of adducts may contribute to the toxic effects of furan.

    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 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 Background. The results of the study conducted to determine whether procalcitonin (PCT and interleukin-6 (IL-6 are more sensitive and specific markers of severe infection in children with febrile neutropenia (FN than routinelly used C-reactive protein (CRP are presented in the article. 68 episodes of FN experienced by 32 patients were divided into three groups according to the site of infection. Group 1: episodes of bacteraemia and/or clinical sepsis (n = 16, group 2: episodes of focal infection (n = 16 and group 3: episodes of fever of unknown origin (FUO (n = 36. Blood samples for further PCT and IL-6 determination were collected on three consecutive days. CRP concentrations were measured daily in each patient until the resolution of fever. PCT, IL-6 and CRP concentrations were measured on one occassion in each of the 18 afebrile patients with malignant disase forming the reference group. Serum PCT and IL-6 concentrations were measured by immunochemiluminometric and immunoenzymatic assay. Receiver Operating Characteristic (ROC curves were used to determine optimum sensitivity, specificity, positive and negative predictive values and diagnostic accuracy of the studied parameters.Conclusions. PCT and IL-6 were found to be earlier and more sensitive markers of severe infection in neutropenic patients than CRP. The erliest one was IL-6, followed by PCT and CRP. Sequential determination of PCT up to 72 hours improved its diagnostic value, which was not the case for IL-6.In patients with gramnegative bacteraemias PCT concentracions were 3–5 times higher comparing to grampositive, whereas IL-6 concentrations were comparable in both groups.

    To explore the relationship between high-sensitivity C-reactive protein (hsCRP) and obesity/metabolic syndrome (MetS) related factors in children. 403 children aged 10-14 and born in Beijing were involved in this study. Height, weight, waist circumference, fat mass percentage (Fat%), blood pressure (BP), hsCRP, triglyceride (TG), total cholesterol (TC), fasting plasma glucose (FPG), high and low density lipoprotein cholesterol (HDL-C, LDL-C) were observed among these children. hsCRP was transformed with base 10 logarithm (lgCRP). MetS was defined according to the International Diabetes Federation 2007 definition. Associations between MetS related components and hsCRP were tested using partial correlation analysis, analysis of covariance and linear regression models. 1) lgCRP was positively correlated with BMI, waist circumference, Fat%,BP, FPG, LDL-C and TC while negatively correlated with HDL-C. With BMI under control, the relationships disappeared, but LDL-C (r = 0.102). 2) The distributions of lgCRP showed obvious differences in all the metabolic indices, in most groups, respectively. With BMI under control, close relationships between lgCRP and high blood pressure/high TG disappeared and the relationship with MetS weakened. 3) Through linear regression models, factors as waist circumference, BMI, Fat% were the strongest factors related to hsCRP, followed by systolic BP, HDL-C, diastolic BP, TG and LDL-C. With BMI under control, the relationships disappeared, but LDL-C(β = 0.045). hsCRP was correlated with child obesity, lipid metabolism and MetS. Waist circumference was the strongest factors related with hsCRP. Obesity was the strongest and the independent influencing factor of hsCRP.

    Insulin resistance (IR) is associated with low adiponectin and elevated high sensitivity C-reactive protein (hsCRP). Osteoprotegerin (OPG) has been shown to be elevated in type 2 diabetes, but whether it reflects underlying IR is unclear. We aimed to compare the ability of serum OPG with adiponectin and hsCRP to act as a marker for IR in individuals with normal and abnormal glucose tolerance.

    In February, 2017, the US Food and Drug Administration approved the blood infection marker procalcitonin for guiding antibiotic therapy in patients with acute respiratory infections. This meta-analysis of patient data from 26 randomised controlled trials was designed to assess safety of procalcitonin-guided treatment in patients with acute respiratory infections from different clinical settings. Based on a prespecified Cochrane protocol, we did a systematic literature search on the Cochrane Central Register of Controlled Trials, MEDLINE, and Embase, and pooled individual patient data from trials in which patients with respiratory infections were randomly assigned to receive antibiotics based on procalcitonin concentrations (procalcitonin-guided group) or control. The coprimary endpoints were 30-day mortality and setting-specific treatment failure. Secondary endpoints were antibiotic use, length of stay, and antibiotic side-effects. We identified 990 records from the literature search, of which 71 articles were assessed for eligibility after exclusion of 919 records. We collected data on 6708 patients from 26 eligible trials in 12 countries. Mortality at 30 days was significantly lower in procalcitonin-guided patients than in control patients (286 [9%] deaths in 3336 procalcitonin-guided patients vs 336 [10%] in 3372 controls; adjusted odds ratio [OR] 0·83 [95% CI 0·70 to 0·99], p=0·037). This mortality benefit was similar across subgroups by setting and type of infection (p interactions >0·05), although mortality was very low in primary care and in patients with acute bronchitis. Procalcitonin guidance was also associated with a 2·4-day reduction in antibiotic exposure (5·7 vs 8·1 days [95% CI -2·71 to -2·15], pacute respiratory infections reduces antibiotic exposure and side-effects, and improves survival. Widespread implementation of procalcitonin protocols in patients with acute respiratory infections thus has the potential to improve antibiotic

    Urinary tract infection (UTI) is a common bacterial infection in children that can result in permanent renal damage. This study prospectively assessed the diagnostic performance of procalcitonin (PCT) for predicting acute pyelonephritis (APN) among children with febrile UTI presenting to the paediatric emergency department (ED). Children aged ≤10 years with febrile UTI admitted to hospital from the paediatric ED were prospectively studied. Blood PCT, C reactive protein (CRP) and white blood cell (WBC) count were measured in the ED. Sensitivity, specificity, predictive values, multilevel likelihood ratios, receiver operating characteristic (ROC) curve analysis and multivariate logistic regression were used to assess quantitative variables for diagnosing APN. The 136 enrolled patients (56 boys and 80 girls; age range 1 month to 10 years) were divided into APN (n=87) and lower UTI (n=49) groups according to (99m)Tc-dimercaptosuccinic acid scan results. The cut-off value for maximum diagnostic performance of PCT was 1.3 ng/ml (sensitivity 86.2%, specificity 89.8%). By multivariate regression analysis, only PCT and CRP were retained as significant predictors of APN. Comparing ROC curves, PCT had a significantly greater area under the curve than CRP, WBC count and fever for differentiating between APN and lower UTI. PCT has better sensitivity and specificity than CRP and WBC count for distinguishing between APN and lower UTI. PCT is a valuable marker for predicting APN in children with febrile UTI. It may be considered in the initial investigation and therapeutic strategies for children presenting to the ED.

    Urinary tract infections (UTIs) are common childhood bacterial infections that may involve renal parenchymal infection (acute pyelonephritis [APN]) followed by late scarring. Prompt, high-quality diagnosis of APN and later identification of children with scarring are important for preventing future complications. Examination via dimercaptosuccinic acid scanning is the current clinical gold standard but is not routinely performed. A more accessible assay could therefore prove useful. Our goal was to study procalcitonin as a predictor for both APN and scarring in children with UTI. A systematic review and meta-analysis of individual patient data were performed; all data were gathered from children with UTIs who had undergone both procalcitonin measurement and dimercaptosuccinic acid scanning. A total of 1011 patients (APN in 60.6%, late scarring in 25.7%) were included from 18 studies. Procalcitonin as a continuous, class, and binary variable was associated with APN and scarring (P children who had APN during the early stages of UTI, as well as those with late scarring.

    Chronic liver disease (CLD) is associated with the destruction of liver parenchyma cell. It is the main cause of morbidity and mortality in most of the developed countries. Oxidative stress and altered levels of different trace elements in serum have been documented for different diseases including inflammation and many liver diseases. This study aims to evaluate the serum level of malondialdehyde (MDA), nitric oxide (NO), antioxidant vitamin C, C-reactive protein (CRP), and zinc (Zn) in CLD patients and to establish a correlation among the study parameters with the severity of inflammatory conditions of CLD. In this study, CLD patients and healthy volunteers were recruited. Total cholesterol and triglyceride were determined by colorimeter using enzymatic method. Serum non-enzymatic antioxidant vitamin C, reactive oxygen species nitric oxide (NO), and malondialdehyde (MDA) were determined by UV-spectrophotometric method. Trace element (Zn) levels were determined by graphite furnace atomic absorption spectroscopy. Independent sample t test and Pearson's correlation test were performed for statistical analysis using the statistical software package SPSS, Version 20. Studies showed that the MDA (p CLD patients than in control subjects. The antioxidant vitamin C (p CLD patients than in control subjects. Elemental Zn showed an inverse relationship with MDA, NO, and CRP but positively correlated with antioxidant capacity, whereas MDA showed a positive correlation with CRP level. Thus, we conclude that attenuated level of Zn and antioxidant in serum play an important role in the inflammatory status of CLD patients by elevating the concentration of MDA, NO, and CRP.

    Serum high-sensitivity C-reactive protein (hsC-rp) is a non-specific marker of inflammation. Elevated hsC-rp levels are found in subjects with cardiovascular diseases (CVDs). Periodontitis may influence hsC-rp levels. To assess periodontal status and hsC-rp serum levels in consecutive subjects hospitalized and diagnosed with acute myocardial infarction (AMI) (n=85) and in a group of carefully matched subjects (gender, age social, ethnic, and smoking habits) without clinical evidence of CVD (n=63). hsC-rp levels, other routine serum values, and clinical periodontal conditions were studied. Subjects with AMI had higher hsC-rp levels than control subjects (pperiodontitis (30% or more sites with>4.0 mm loss of alveolar bone) had serum hsC-rp>1.8 mg/l was 1.5 (95% CI: 1.1-7.3, pperiodontal parameters in an explanatory model to hsC-rp values.

    C-reactive protein (CRP) has been implicated as a possible mediator of the association between periodontitis and several systemic diseases. This study evaluated the impact of nonsurgical periodontal treatment on the serum levels of CRP in chronic kidney disease (CKD) patients on hemodialysis. A total of 77 CKD patients on hemodialysis were included in this study. At baseline, periodontal examination was assessed for all the patients, and chronic periodontitis was defined through clinical attachment level and probing pocket depth, according to the American Association of Periodontology. Nonsurgical periodontal treatment was performed and serum levels of CRP were evaluated at baseline and 8 weeks after periodontal treatment. Periodontal treatment resulted in significant reductions in CRP levels (p periodontitis. Periodontitis is an important source of systemic inflammation in CKD patients. Nonsurgical periodontal treatment can effectively reduce the serum level of CRP in these patients.

    Full Text Available Periodontitis is a local inflammatory process mediating the destruction of periodontal tissues, triggered by bacterial insult. Recent evidence suggests the presence of chronic inflammatory periodontal disease may significantly affect systemic health conditions such as coronary heart disease, stroke, or adverse pregnancy outcome. C-reactive protein (CRP is an acute phase protein which reflects a measure of the acute phase response. CRP is used as one of the markers of choice in monitoring the acute phase response because it increases to a relatively high concentration compared to basal concentration. CRP has been shown to predict cardiovascular (CV mortality in recent studies, and elevated CRP levels have been observed in middle-aged patients with periodontitis. Combination of chronic infections like periodontitis with elevated CRP is associated with higher chronic heart diseases. The recognition of the relationship between periodontal diseases and atherosclerotic events is relatively recent and mostly based on the inflammatory hypothesis of atherosclerosis. Periodontal disease is one of the risk factors for cardiovascular disease and possibly one of its causes. Hence, even associations of modest magnitude have a large impact. The cost to the society directly attributable to atherosclerotic sequelae is very large. Periodontitis is treatable; moreover, it is preventable. Experimental conformation of this shows that another widely prevalent and preventable contributor to the burden of cardiovascular disease would be added to the options available of the clinicians and public health practitioners for the control of the epidemic of cardiovascular disease.

    Candidemia is a major infectious complication in neonatal patients. The isolation of yeasts from blood is still the "gold standard" for its diagnosis, but other laboratory markers (i.e., circulating antigens) have been studied with varying specificities and sensitivities. The aim of this study was to evaluate the role of procalcitonin for the diagnosis of candidemia in neonatal patients at high risk. To verify if the use of different commercial methods can highlight dissimilar results of sensitivity and/or specificity, the determination of procalcitonin serum levels was estimated by two systems. Overall, 90 patients from a Neonatal Intensive Care Units were enrolled, of whom six developed Candida bloodstream infection. Four of six infants with candidemia had slight increase of procalcitonin values (0.5-1 ng/mL). Only one baby showed very high levels but he had fungal and bacterial sepsis at the same time, while no elevation was observed in the sixth patient. No statistically significant difference was observed between two different methods at the time of monitoring (p>0.643). Both methods showed a sensitivity of 83.3 % at diagnosis, while the specificity was 73.8 and 63.1 % by methods A and B, respectively. In the light of the low sensibility and specificity of this assay, we can assume that the determination of procalcitonin would not seem to play a significant role in the diagnosis of fungal infection in neonatal patients.

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

Conclusion: Locally delivered tetracycline as a better treatment modality compared to SRP alone.

  11. Serum C-Reactive Protein (CRP), Target for Therapy or Trouble?

    High sensitivity serum C-reactive protein (hs-CRP) has come into clinical use as a marker of risk for cardiovascular disease (CVD). In addition to a role as a marker of disease, CRP has also been implicated in the pathogenesis of CVD. Specific small-molecule inhibitors of CRP have recently been developed with the intent of mitigating cardiac damage during acute myocardial infarction. However, the use of CRP, both as a risk marker and a disease target are controversial for several reasons. Serum hs-CRP concentrations can be elevated on the basis of genetics, female gender, and non-Caucasian ethnicity. It is not clear, in these contexts, that elevations of hs-CRP have any pathological significance. As a non-specific indicator of inflammation, CRP is also not a specific indicator of a single disease state such as cardiovascular disease but elevated concentrations can be seen in association with other comorbidities including obesity and pulmonary disease. In sharp contrast to the proposed inhibition of CRP for cardiovascular disease treatment, the infusion of CRP has been shown to have profound therapeutic benefits for autoimmune disease and septic shock. The balance between the risks and benefits of these competing views of the role of CRP in disease and disease therapy is reminiscent of the ongoing controversy regarding the use of non-steroidal anti-inflammatory drugs (NSAIDs) for musculoskeletal disease and their cardiovascular side effects. Soon, NSAIDs may not be the only agents about which Rheumatologists and Cardiologists may spar.

    To explore the clinical value of determination of serum troponin I (cTnI) and hyper-sensitive C-reactive protein(hs-CRP) around extracorporeal circulation, cTnI and hs-CRP were determined in 46 patients with congenital heart disease before and after the surgery (0, 24h, 3d, 7d, 15d respectively). At the same time, electrocardiogram(ECG), hemo dynamics and other adverse events were recorded. Before the surgery results of cTnI and hs-CRP were in nor- mal range, wheraas after surgery the level of cTnI went up, reached its peak at 24h, and returned normal on d7. The level of hs-CRP begin to increase at 24h, returned normal on dT. Its level was higher in patients with postoperative infection than that in patients without infection, however, it returned normal after anti-inflammatory treatment. Therefore, cTnI and hs-CRP may be taken as diagnostic criteria of prognosis in patient after extracorporea circulation surgery. Postoperative infection around extracorporeal circulation surgery could be prevented by monitring hs-CRP concentration. (authors)

    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 (HR peak : 149±12 vs 139±10, P=0.009), peak oxygen uptake (VO 2peak : 24.2±3.2 vs 18.9±2.8, P<0.001), and anaerobic threshold (VO 2VT : 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

  19. C-reactive protein bearing cells are a subpopulation of natural killer cell precursors

    Baum, L.L.; Krueger, N.X.

    1986-01-01

    Cell surface C-reactive protein (S-CRP) is expressed on the surface membrane of a small percentage of lymphocytes. Anti-CRP inhibits natural killer (NK) function. Since NK effectors are heterogeneous, they suspected that the cells expressing S-CRP (CRP + ) might respond differently to stimulation than the NK effectors lacking S-CRP (CRP - ). Methods were developed to separate CRP + and CRP - lymphocytes and their functional responses were examined and compared. These techniques are dependent upon the binding of CRP to its ligands, C-polysaccharide (CPS) or Phosphocholine (PC). The first method involves rosette formation with CPS coupled autologous red blood cells; the second method utilizes the binding of CRP + lymphocytes to PC-sepharose. Lymphocytes separated using either of these techniques yield similar results. CRP - lymphocytes respond to 3 day incubation with PHA or Il-2 by producing effectors which kill 51 Cr labeled K562 tumor cells, CRP + precursors do not. CRP + lymphocytes respond to a 5 day incubation with inactivated K562 by producing effectors which kill K562; CRP - precursors do not. NK functional activity of both is increased by incubation with interferon. This ability to respond differently to stimulation suggests that CRP + and CRP - cells are functionally distinct

    This study utilized a novel multisystem approach to investigate the effect of observed parental behavior on the relationship between biological mechanisms associated with disease processes (i.e., autonomic physiology and immune response) among their adolescent children. Thirty-three adolescents (23 males), aged 11-13, and their parents participated in a laboratory session in which adolescents provided baseline measures of autonomic (sympathetic) activity, and adolescents and 1 parent participated in a laboratory based dyadic conflict resolution interaction task. This included 3 male parent/male adolescent dyads, 20 female parent/male adolescent dyads, 3 male parent/female adolescent dyads, and 7 female parent/female adolescent dyads. Approximately 3 years later, adolescents provided a salivary measure of C-Reactive Protein (sCRP) to index inflammation. Analyses revealed a positive association between sympathetic activity and sCRP, as well as a moderating role of positive parental behavior in this relationship, such that the association between sympathetic activity and sCRP was greater among adolescents whose parents displayed shorter duration of positive affect.

    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. 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. 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. 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.

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

    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.

Eighty-four victims with severe concomitant injury were examined. Twenty-five (29.7% patients developed sepsis, death being observed in 83.3%. CRP was daily determined in the sera of the victims, by using CRP latex test kits (HUMATEX, Germany. On days 1, 3, 7, 10, and 15 after injury, serum and lymphocytic culture IL-2, IL-4, TNF-a, IFN-y, and HLA-DR were studied on an automatic Elx 800 Universal Microplate Reader enzyme immunoassay analyzer (BIO-TEK INSTRUMENTS, Inc., USA, by applying enzyme immunoassay systems (OOO «Cytokine», Saint Petersburg, Russia.Results. No complications were observed with a CRP level of 40 mg/l on day 1 and its further reduction. The CRP level of 40 mg/l on day 1 (without use of glucocorticoids and its prolonged increase were determined in visceral inflammatory and infectious complications. The CRP level of 120 mg/l within the first 7 days was noted in subsequently developed sepsis. Glucocorticoids and specific immune drugs resulted in a reduction or complete disappearance of CRP. When the latter were discontinued, CRP appeared in the quantity reflecting the effect of treatment. In the absence of multiple organ dysfunctions, the level of CRP decreased as the infectious process diminished. The low level of CRP and the activation of an infectious process suggest the areactivity of an organism. With the CRP level of 40 mg/l, the spontaneous production and level of blood IL-4 increased less significantly, whereas those of IFN-y rose more substantially; the induced activity of TNF-a also more drastically decreased (by 10 times versus 2.2 with a CRP level of 40 mg/l. Irrespective of the level of CRP, the induced activity of IL-4 decreased by 59%, suggesting immunosuppression. There was no association of CRP with IL-2 and HLA-DR.Conclusion. Daily blood CRP analysis in injury makes it possible to predict visceral

    Chronic periodontitis in amultifactorial inflammatory disease which is caused by various microorganisms. Many studies have found close association between chronic periodontitis and C-reactive protein (CRP). CRPis an inflammatory marker which increases in all inflammatory condition. The present clinical study was designed to show the effect of periodontal treatment on the CRP levels of gingival crevicular fluid and to determine the effect of nonsurgical therapy in minimizing the CRP levels in chronic generalized periodontitis. Gingival crevicular fluid was collected using a micro capillary pipette that was hand calibrated at every 1 mm till 10 mm, from selected sites in the subjects on the 1st, 14th and 45th days. Decreased CRP levels of gingival crevicular fluid were observed at the end of the study. There was a 37% reduction in probing pocket depth and 45% gain in clinical attachment level and a reduction of about 57% after 14 days and 90% reduction of CRP levels in gingival crevicular fluid after 45 days. Thus, the results show that the presence of CRP level is more significant in gingival crevicular fluid and confirms the underlying inflammatory component of the disease activity in chronic periodontitis.

    Determination by a high sensitivity technique of serum C-reactive protein (CRP), a sensitive marker of inflammation in women with preeclampsia compared to normal pregnancy and investigation of the relationship between CRP and the severity of the preeclamptic syndrome. The study included 40 women with preeclampsia and 40 control subjects with normal pregnancies in the last trimester of pregnancy. The serum CRP concentration was determined using the universal high sensitivity immunoturbidimetric assay. The serum CRP concentration was significantly higher (p preclampsia (5.69 +/- 1.8 mg/L) compared to normal pregnancy (2.89 +/- 1.2 mg/L). In women with preeclampsia, CRP correlated positively and significantly with diastolic blood pressure, proteinuria and uric acid levels. Maternal CRP values also correlated negatively and significantly with fetal weight at birth. Our results demonstrate that serum CRP is increased in preeclampsia and represents a marker of the severity of the preeclamptic syndrome and of fetal weight at birth. Taking into consideration these observations and the fact that CRP testing is rapid and relatively inexpensive, we recommend the use of this acute phase reagent in clinical practice, in all women with preeclampsia in order to establish the prognosis of the disease.

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

    Directory of Open Access Journals (Sweden)

    Mika Kivimäki

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

    Cardiovascular disease in humans and dogs is associated with mildly increased circulating concentrations of C-reactive protein (CRP). Few studies have evaluated associations between circulating CRP and canine myxomatous mitral valve disease (MMVD) and the results reported have been divergent....... The aim of this study was to investigate whether serum concentrations of CRP, determined using a novel automated canine-specific high -sensitivity CRP assay (Gentian hsCRP), were associated with severity of MMVD and selected clinical variables in dogs. The study included 188 client-owned dogs...... with different severities of MMVD. Dogs were classified based on ACVIM consensus statement guidelines (group A, n = 58; group BI, n = 56; group B2, n = 38; group C, n = 36). Data were analysed using descriptive statistics and multiple regression analysis. Dogs with congestive heart failure (CHF; group C) had...

    The autolysis loop of activated protein C (APC) is five residues longer than the autolysis loop of other vitamin K-dependent coagulation proteases. To investigate the role of this loop in the zymogenic and anticoagulant properties of the molecule, a protein C mutant was constructed in which the autolysis loop of the protein was replaced with the corresponding loop of factor X. The protein C mutant was activated by thrombin with approximately 5-fold higher rate in the presence of Ca2+. Both kinetics and direct binding studies revealed that the Ca2+ affinity of the mutant has been impaired approximately 3-fold. The result of a factor Va degradation assay revealed that the anticoagulant function of the mutant has been improved 4-5-fold in the absence but not in the presence of protein S. The improvement was due to a better recognition of both the P1-Arg506 and P1-Arg306 cleavage sites by the mutant protease. However, the plasma half-life of the mutant was markedly shortened due to faster inactivation by plasma serpins. These results suggest that the autolysis loop of protein C is critical for the Ca(2+)-dependence of activation by thrombin. Moreover, a longer autolysis loop in APC is not optimal for interaction with factor Va in the absence of protein S, but it contributes to the lack of serpin reactivity and longer half-life of the protease in plasma.

    Shift work is a risk factor for inflammation, hypertension, and cardiovascular disease. This increased risk cannot be fully explained by classical risk factors. Shift workers' behavioral and environmental cycles are typically misaligned relative to their endogenous circadian system. However, there is little information on the impact of acute circadian misalignment on cardiovascular disease risk in shift workers, independent of differences in work stress, food quality, and other factors that are likely to differ between night and day shifts. Thus, our objectives were to determine the independent effect of circadian misalignment on 24-h high-sensitivity C-reactive protein (hs-CRP; a marker of systemic inflammation) and blood pressure levels-cardiovascular disease risk factors-in chronic shift workers. Chronic shift workers undertook two 3-day laboratory protocols that simulated night work, comprising 12-hour inverted behavioral and environmental cycles (circadian misalignment) or simulated day work (circadian alignment), using a randomized, crossover design. Circadian misalignment increased 24-h hs-CRP by 11% ( p shift workers. This may help explain the increased inflammation, hypertension, and cardiovascular disease risk in shift workers.

    Inappropriate antibiotic use for acute respiratory tract infections is common in primary health care, but distinguishing serious from self-limiting infections is difficult, particularly in low-resource settings. We assessed whether C-reactive protein point-of-care testing can safely reduce antibiotic use in patients with non-severe acute respiratory tract infections in Vietnam. We did a multicentre open-label randomised controlled trial in ten primary health-care centres in northern Vietnam. Patients aged 1-65 years with at least one focal and one systemic symptom of acute respiratory tract infection were assigned 1:1 to receive either C-reactive protein point-of-care testing or routine care, following which antibiotic prescribing decisions were made. Patients with severe acute respiratory tract infection were excluded. Enrolled patients were reassessed on day 3, 4, or 5, and on day 14 a structured telephone interview was done blind to the intervention. Randomised assignments were concealed from prescribers and patients but not masked as the test result was used to assist treatment decisions. The primary outcome was antibiotic use within 14 days of follow-up. All analyses were prespecified in the protocol and the statistical analysis plan. All analyses were done on the intention-to-treat population and the analysis of the primary endpoint was repeated in the per-protocol population. This trial is registered under number NCT01918579. Between March 17, 2014, and July 3, 2015, 2037 patients (1028 children and 1009 adults) were enrolled and randomised. One adult patient withdrew immediately after randomisation. 1017 patients were assigned to receive C-reactive protein point-of-care testing, and 1019 patients were assigned to receive routine care. 115 patients in the C-reactive protein point-of-care group and 72 patients in the routine care group were excluded in the intention-to-treat analysis due to missing primary endpoint.

    The diagnostic value of C-reactive protein (CRP) level for pneumonia in children is unknown. As a first step in the assessment of the value of CRP, a diagnostic study was performed in children at an emergency department (ED). In this cross-sectional study, data were retrospectively collected from children presenting with suspected pneumonia at the ED of Antonius Hospital Nieuwegein in The Netherlands between January 2007 and January 2012. Diagnostic outcome was pneumonia yes/no according to independent radiologist. (Un)adjusted association between CRP level and pneumonia and diagnostic value of CRP were calculated. Of 687 presenting children, 286 underwent both CRP measurement and chest radiography. 148 had pneumonia (52%). The proportion of pneumonia increased with CRP level. Negative predictive values declined, but positive predictive values increased with higher CRP thresholds. Univariable odds ratio for the association between CRP level and pneumonia was 1.2 (95% CI 1.11-1.21) per 10 mg/L increase. After adjustment for baseline characteristics CRP level remained associated with pneumonia. CRP level has independent diagnostic value for pneumonia in children presenting at the ED with suspected pneumonia, but low levels do not exclude pneumonia in this setting. These results prompt evaluation of CRP in primary care children with LRTI. Copyright © 2013 Elsevier Ltd. All rights reserved.

    The collectins, a group of humoral C-type lectins, have globular and collagen-like regions and share structural features with the complement protein C1q. The question was asked if autoantibodies to the collagen-like region of C1q (anti-C1qCLR) might cross-react with collectins, such as mannan-binding protein (MBP), lung surfactant protein A (SP-A) and bovine conglutinin (BK). Anti-C1qCLR antibodies of the systemic lupus erythematosus (SLE) type and anti-C1qCLR antibodies of the hypocomplementemic urticarial vasculitis syndrome (HUVS) type were investigated. Cross-absorption and elution experiments combined with antibody detection by enzyme-linked immunosorbent assay (ELISA) and immunoblot analysis gave no evidence of cross-reactive anti-C1qCLR antibodies. However, one serum with HUVS type anti-C1qCLR antibodies contained anti-MBP antibodies that were cross-reactive with SP-A. Judging from results of ELISA inhibition experiments and immunoblot analysis, four SLE sera contained antibodies to native BK, while two sera with HUVS type anti-C1qCLR antibodies contained antibodies to epitopes of denatured BK. This might imply that autoimmunity to collagen-like structures is not restricted to C1qCLR in HUVS and HUVS/SLE overlap syndromes.

    Full Text Available High sensitivity serum C-reactive protein (hs-CRP has come into clinical use as a marker of risk for cardiovascular disease (CVD. In addition to a role as a marker of disease, CRP has also been implicated in the pathogenesis of CVD. Specific small-molecule inhibitors of CRP have recently been developed with the intent of mitigating cardiac damage during acute myocardial infarction. However, the use of CRP, both as a risk marker and a disease target are controversial for several reasons. Serum hs-CRP concentrations can be elevated on the basis of genetics, female gender, and non-Caucasian ethnicity. It is not clear, in these contexts, that elevations of hs-CRP have any pathological significance. As a non-specific indicator of inflammation, CRP is also not a specific indicator of a single disease state such as cardiovascular disease but elevated concentrations can be seen in association with other comorbidities including obesity and pulmonary disease. In sharp contrast to the proposed inhibition of CRP for cardiovascular disease treatment, the infusion of CRP has been shown to have profound therapeutic benefits for autoimmune disease and septic shock. The balance between the risks and benefits of these competing views of the role of CRP in disease and disease therapy is reminiscent of the ongoing controversy regarding the use of non-steroidal anti-inflammatory drugs (NSAIDs for musculoskeletal disease and their cardiovascular side effects. Soon, NSAIDs may not be the only agents about which Rheumatologists and Cardiologists may spar.

    To explore the independent correlation between serum uric acid and low-grade inflammation (measured by high-sensitivity C-reactive protein, hs-CRP) in postmenopausal women. A total of 378 healthy Iranian postmenopausal women were randomly selected in a population-based study. Circulating hs-CRP levels were measured by highly specific enzyme-linked immunosorbent assay method and an enzymatic calorimetric method was used to measure serum levels of uric acid. Pearson correlation coefficient, multiple linear regression and logistic regression models were used to analyze the association between uric acid and hs-CRP levels. A statistically significant correlation was seen between serum levels of uric acid and log-transformed circulating hs-CRP (r = 0.25, p uric acid levels (β = 0.20, p uric acid levels (odds ratio =1.52, 95% confidence interval 1.18-1.96). Higher serum uric acid levels were positively and independently associated with circulating hs-CRP in healthy postmenopausal women.

    Full Text Available Background: Recently growing evidence indicates that obesity and diabetes are states of inflammation associated with elevated circulation of inflammatory mediators. Excess adiposity and oxidative stress, induced by feeding, may also lead to a state of low-grade inflammation. Objective: This study aimed at investigating energy balance and distribution in relation to low-grade inflammation among patients with type 2 diabetes. Design: A cross-sectional study included 198 male and female patients with type 2 diabetes. Patients’ weight, height, waist circumference, total body fat and truncal fat percent, energy, and macronutrient intake were measured. Venous blood specimens were collected, and levels of HbA1c and serum levels of high-sensitivity C-reactive protein (hs-CRP were determined. Results: After adjusting for covariates (body mass index, total body fat, and truncal fat, energy balance was positively correlated with hs-CRP and HbA1c. A positive energy balance was also associated with increased waist circumference and truncal fat percent (p<0.05. Total energy intake, percent energy from fat (p=0.04, and percent energy from proteins (p=0.03, but not percent energy from carbohydrates (p=0.12, were also correlated with higher hs-CRP levels among poorly glycemic-controlled patients. Conclusion: Positive energy balance is associated with elevations in hs-CRP. Increased energy intake and increased percentages of energy from fat and protein are associated with elevated hs-CRP among patients with poor glycemic control.

    The post-translational modification of proteins is a well-known endogenous mechanism for regulating protein function and activity. Cellular proteins are also susceptible to post-translational modification by xenobiotic agents that possess, or whose metabolites possess, significant electrophilic character. Such non-physiological modifications to endogenous proteins are sometimes benign, but in other cases they are strongly associated with, and are presumed to cause, lethal cytotoxic consequences via necrosis and/or apoptosis. The Reactive Metabolite Target Protein Database (TPDB) is a searchable, freely web-accessible (http://tpdb.medchem.ku.edu:8080/protein_database/) resource that attempts to provide a comprehensive, up-to-date listing of known reactive metabolite target proteins. In this report we characterize the TPDB by reviewing briefly how the information it contains came to be known. We also compare its information to that provided by other types of "-omics" studies relevant to toxicology, and we illustrate how bioinformatic analysis of target proteins may help to elucidate mechanisms of cytotoxic responses to reactive metabolites.

    Periodontitis may exert an infectious and inflammatory burden, evidenced by increased C-reactive protein (CRP). This burden may impair blood glucose control (HbA1c). The aim of our study was to analyze whether periodontitis severity as measured with the periodontal inflamed surface area (PISA) and CRP predict HbA1c levels in a group of healthy Indonesians and a group of Indonesians treated for type 2 diabetes mellitus (DM2). A full-mouth periodontal examination, including probing pocket depth, gingival recession, clinical attachment loss, plaque index and bleeding on probing, was performed in 132 healthy Indonesians and 101 Indonesians treated for DM2. Using these data, PISA was calculated. In addition, HbA1c and CRP were analyzed. A validated questionnaire was used to assess smoking, body mass index (BMI), education and medical conditions. In regression analyses, it was assessed whether periodontitis severity and CRP predict HbA1c, controlling for confounding and effect modification (i.e., age, sex, BMI, pack years, and education). In healthy Indonesians, PISA and CRP predicted HbA1c as did age, sex, and smoking. In Indonesians treated for DM2, PISA did not predict HbA1c. Periodontitis may impair blood glucose regulation in healthy Indonesians in conjunction with elevated CRP levels. The potential effect of periodontitis on glucose control in DM2 patients may be masked by DM2 treatment. periodontitis may impair blood glucose control through exerting an inflammatory and infectious burden evidenced by increased levels of CRP.

    Full Text Available Currently, differential diagnosis of systemic bacterial infection and active rheumatic process remains a challenging problem in rheumatology. In the review, current data on the role of procalcitonin biomarker in diagnosis and differential diagnosis of rheumatic diseases (RD and infectious pathology are presented. In particular, some authors recommend procalcitonin (PCT test as a marker of bacterial infection in bones and joints at levels above 0.5 ng/ml; at PCT level below 0.3 ng/ml, infection can be ruled out. In patients with microcrystalline arthritis, data on the significance of PCT for differential diagnosis are contradictory. PCT level doesn’t correlate with systemic lupus erythematosus activity and is elevated only during bacterial infection proportionally to its systematicity. In some studies, elevated PCT level was observed in ANCA-associated vasculitis with high activity without bacterial infection. It was shown that in 80 % of adults with Still’s disease, PCT level was higher than the threshold value even without infection. For patients with RD hospitalized in intensive care units, PCT clearance is a more informative predictive characteristic than its level, regardless of the cause of PCT elevation (infection, injury, severe organ damage, etc.; slowdown of its decrease is a factor of poor prognosis and is associated with higher mortality. At the same time, PCT level positively correlates with the SOFA score in presence of bacterial infection. For some rheumatic diseases, the threshold PCT value at which the test has optimal sensitivity and specificity is yet to be established. Nonetheless, PCT should be evaluated in relation to the clinical picture and data of additional examinations. The effect of various therapy methods used in rheumatology on PCT level requires further research.

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

    C-reactive protein (CRP) has evolved as an inflammatory risk marker of cardiovascular disease. Several single-nucleotide polymorphisms at the CRP locus have been found to be associated with CRP levels. The aim of the present study was to investigate CRP levels and genetic variants in etiological subtypes of ischemic stroke. The Sahlgrenska Academy Study on Ischemic Stroke (SAHLSIS) comprises 600 consecutive ischemic stroke cases (18 to 69 years) and 600 matched controls from western Sweden. Stroke subtypes were defined by the TOAST classification. Serum CRP levels were determined by a high-sensitivity immunometric assay. CRP levels were significantly higher for all ischemic stroke subtypes compared with controls, both in the acute phase and at the 3-month follow-up. After adjustment for traditional risk factors, CRP at follow-up was related to higher odds ratios (ORs) of overall ischemic stroke (OR, 1.25; 95% CI, 1.09 to 1.43) and large-vessel disease (OR, 1.48; 95% CI, 1.09 to 2.00). The CRP -286C>T>A, 1059G>C, and 1444C>T single-nucleotide polymorphisms showed significant associations with CRP levels. However, neither CRP genotypes nor haplotypes showed an association to overall ischemic stroke. This is the first large study on CRP in different TOAST subtypes in a young ischemic stroke population. CRP levels differed between etiological subtypes of ischemic stroke both in the acute phase and at the 3-month follow-up. CRP at follow-up was associated with overall ischemic stroke and the large-vessel disease subtype. Genetic variants at the CRP locus were associated with CRP levels, but no association was detected for overall ischemic stroke.

    To analyze the usefulness and ability of procalcitonin (PCT) to predict the presence of bacteremia in patients with community-acquired pneumonia (CAP) caused by Streptococcus pneumoniae (S. pneumoniae) or other bacteria. This is an observational, prospective and descriptive study involving patients who were diagnosed with CAP in our Emergency Department. Data collected included socio-demographic and comorbidity variables, Charlson index, stage in the Pneumonia Severity Index and criteria of severe NAC, microbiologic studies and biomarker determinations (PCT and C reactive protein). The follow-up was carried out during 30 days to calculate the predictive power and the diagnostic performance for bacteremia caused or not by S. pneumoniae. Four hundred and seventy-four patients were finally included in the study. Blood cultures were positive in 85 individuals (17.9%) and S. pneumoniae was identified as the responsible pathogen in 75 of them (88.4%) (in 5 cases together with another agent). The area under the Receiver Operating Characteristic curve for PCT to predict bacteremia (caused by S. pneumoniae or not) was 0.988 (95% confidence interval 0.908-0.995; P98% and>10, respectively. The most frequently isolated serotypes of S. pneumoniae were 19A, 7F, 1 and 3. The highest mean levels of PCT were found in serotypes 7F, 19A, 3 and 1, which showed statistically significant differences with regard to the others serotypes considered (P=.008). Serotypes associated with the highest percentage of severe sepsis-septic shock, 30-days mortality and multi-lobe or bilateral affection were 3, 1 and 19A; 1, 3 and 19A; and 3, 19A and 6A, respectively. PCT had a remarkable diagnostic ability to discard or suspect bacteremia and to guide the etiology of CAP caused by S. pneumoniae. Serotypes 1, 3, 19A and 7F showed greater frequency, systemic inflammatory response and clinical severity. Copyright © 2013 Elsevier España, S.L. All rights reserved.

    Inflammation plays a pivotal role in the formation and progression of ischemic stroke. Recently, more and more epidemiological studies have focused on the association between C-reactive protein (CRP) -717A > G and -286C > T > A genetic polymorphisms and ischemic stroke. However, the findings of these researches are not conclusive. We performed a meta-analysis to determine whether these two polymorphisms are associated with the risk of ischemic stroke. Eligible studies were identified from the database of PubMed, Medline, Embase, Web of Science, CNKI, Weipu, and Wanfang. We calculated odds ratios (ORs) with 95% confidence intervals (CIs) to assess the strength of the association. Four articles were included in our study, including 1926 cases and 2678 controls for -717A > G polymorphism, 652 cases and 1103 controls for -286C > T > A polymorphism. The results of meta-analysis showed that single nucleotide polymorphism (SNP) -717A > G was not significantly associated with the risk of ischemic stroke (GG vs. AA, OR = 1.12, 95% CI = 0.83-1.50, P = 0.207; GG + GA vs. AA, OR = 1.04, 95% CI = 0.93-1.17, P = 0.533; GG vs. GA + AA, OR = 1.10, 95% CI = 0.82-1.47, P = 0.220). Meta-analysis of SNP - 286C > T > A also demonstrated no statistical evidence of a significant association with the risk of ischemic stroke (AA vs. CC, OR = 0.86, 95% CI = 0.59-1.25, P = 0.348; AA vs. CC, OR = 0.92, 95% CI = 0.80-1.06, P = 0.609; AA vs. CC, OR = 0.89, 95% CI = 0.62-1.30, P = 0.374). This meta-analysis demonstrated little evidence to support a role of CRP gene -717A > G, -286C > T > A polymorphisms in ischemic stroke predisposition. However, to draw comprehensive and more reliable conclusions, further larger studies are needed to validate the association between CRP gene polymorphisms and ischemic stroke in various ethnic groups.

    Elevated inflammation is a proposed mechanism relating chronic diseases to cognitive dysfunction. The objective of this study was to test the hypothesis that greater levels of inflammation, as measured by the proinflammatory cytokine interleukin-6 (IL-6) and C-reactive protein, are associated with faster rates of cognitive decline among cognitively intact community-dwelling older women. We analyzed 336 women from the Women's Health and Aging Study II. Cognitive assessments were performed at baseline and every 18-36 months, and included the following domains: immediate and delayed memory (Hopkins Verbal Learning Test), psychomotor speed (Trail Making Test, Part A), and executive function (Trail Making Test, Part B). Aggregate measures of IL-6 and C-reactive protein, based on the average from visits one and two, were analyzed categorically. Random effects models were employed to test the relationship between tertiles of each inflammatory marker and changes in cognitive domain scores over 9 years. Moderate and high levels of IL-6 predicted early declines in psychomotor speed by 1.0 connection/min per year. There were no differences in baseline scores or rates of change across tertiles of IL-6 in memory or executive function. No differences were observed across tertiles of C-reactive protein for all cognitive domains. Higher levels of serum IL-6 were associated with greater declines in psychomotor speed over 9 years. This finding could suggest that elevated IL-6 may result in microvascular changes that may lead to damage of myelin sheaths that line neuronal axons, leading to decreased neuron propagation and impaired processing speed; however, mechanistic studies are needed to evaluate these hypotheses. © The Author 2014.

    An immunoradiometric assay (IRMA) for C-reactive protein (CRP) was developed using magnetisable cellulose particles as the solid-phase support for anti-CRP antibodies. 125 I-labelled immunopurified anti-CRP antibody was used to quantitate the amount of CRP taken up by the solid phase. Unbound label was easily and rapidly removed by decantation after sedimenting the particles on a magnet. The assay could detect 1 μg CRP/l and had a range of up to 10 mg/l with the portion of the standard curve between 10 μg/l and 2-3 mg/l being linear. Fifty samples per hour could be processed manually from serum to CRP result with an intra-assay CV of 5.2% and an inter-assay CV of 10.0%, based on 5 replicates of 5 samples with CRP levels between 2 mg/l and 180 mg/l run in 5 separate assays. Fifty clinical samples were assayed in parallel with a standard electroimmunoassay and yielded a linear correlation coefficient (r) of 0.975 and a slope of 0.98. With its single, brief incubation step including all reagents and its simple phase separation procedure the present method may be the assay of choice when precise measurement of CRP concentrations is required rapidly.

    Full Text Available OBJECTIVES AND BACKGROUND The management of sepsis requires a hasty identification of infection, through the application of different dynamic strategies in prehospital and hospital conditions, through the implementation of a number of changes and by measuring the outcome of these changes thus ensuring a decrease in the mortality rate and allowing a rapid identification of the infection MATERIALS AND METHODS Procalcitonin (PCT was used as a marker of sepsis in emergency departments. Due to its sensitivity and molecular peculiarities, procalcitonin allows a rapid diagnosis of severe bacterial infections, and is able to differentiate viral infections from bacterial ones. It is also able to differentiate an infectious process from an inflammation, thus sketching a clinically applicable protocol that can be implemented and continuously improved. RESULTS The identification of the infectious process in the emergency department within 24 hours leads to a decreased in the mortality rate. Speedy diagnostic methods of infection based on the determination of specific, rapidly measurable, markers – procalcitonin in our case - can confirm the presence of sepsis and its’ outcome. CONCLUSIONS Prehospital determination of procalcitonin (PCT is recommended in the early diagnosis of sepsis and is also an indicator of its severity, starting from a solid theoretical database that is justified by the efficiency and effectiveness of its usage.

    The toxic effects of many simple organic compounds stem from their biotransformation to chemically reactive metabolites which bind covalently to cellular proteins. To understand the mechanisms of cytotoxic responses it may be important to know which proteins become adducted and whether some may be common targets of multiple toxins. The literature of this field is widely scattered but expanding rapidly, suggesting the need for a comprehensive, searchable database of reactive metabolite target proteins. The Reactive Metabolite Target Protein Database (TPDB) is a comprehensive, curated, searchable, documented compilation of publicly available information on the protein targets of reactive metabolites of 18 well-studied chemicals and drugs of known toxicity. TPDB software enables i) string searches for author names and proteins names/synonyms, ii) more complex searches by selecting chemical compound, animal species, target tissue and protein names/synonyms from pull-down menus, and iii) commonality searches over multiple chemicals. Tabulated search results provide information, references and links to other databases. The TPDB is a unique on-line compilation of information on the covalent modification of cellular proteins by reactive metabolites of chemicals and drugs. Its comprehensiveness and searchability should facilitate the elucidation of mechanisms of reactive metabolite toxicity. The database is freely available at http://tpdb.medchem.ku.edu/tpdb.html.

    2014-01-01

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

    Periodontitis has been identified as a potential risk factor for systemic pathologies such as cardiovascular disease (CVD). The aims of this investigation were to assess the relationship between periodontitis and systemic inflammatory factor, as well as to discover whether there is a relation to the severity of periodontitis and to the periodontopathogens. Periodontal examinations and serum C-reactive protein (CRP) level measurements were performed in 50 patients with periodontitis. Periodontal health indicators included the gingival bleeding on probing index and periodontal disease status. The patients with moderate periodontitis had low attachment loss and pocket depth periodontitis had high attachment loss and pocket depth >5 mm. The control group comprised 25 volunteers with healthy gingiva, gingival sulcus periodontal parameters and CRP levels were significantly higher in the patients with periodontitis. Patients who had severe periodontitis, with high levels of mean clinical attachment loss, and subjects with moderate periodontitis had higher mean CRP levels. The percentage of subjects with elevated levels of CRP >5 mg/l was greater in the higher clinical attachment loss group compared to the group with lower attachment loss. The presence of P. gingivalis and A. actinomycetemcomitans were also associated with elevated CRP levels and poor periodontal status. Periodontitis and the presence of P. gingivalis are associated with an enhanced inflammatory response expressed by higher CRP levels. The association of periodontitis with CRP levels appears to be a contributing factor for CVD and might be a possible intermediate pathway in this association.

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

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

    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.

    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 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.

    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 Raised blood C-reactive protein (CRP level is a predictor of cardiovascular events, but whether blood CRP is causal in the disease process is unknown. The latter would best be defined by pharmacological inhibition of the protein in the context of a randomized case-control study. However, no CRP specific drug is currently available so such a prospective study cannot be performed. Blood CRP is synthesized primarily in the liver and the liver is an organ where antisense oligonucleotide (ASO drugs accumulate. Taking advantage of this we evaluated the efficacy of CRP specific ASOs in rodents with experimentally induced cardiovascular damage. Treating rats for 4 weeks with a rat CRP-specific ASO achieved >60% reduction of blood CRP. Notably, this effect was associated with improved heart function and pathology following myocardial infarction (induced by ligation of the left anterior descending artery. Likewise in human CRP transgenic mice treated for 2 weeks with a human CRP-specific ASO, blood human CRP was reduced by >70% and carotid artery patency was improved (2 weeks after surgical ligation. CRP specific ASOs might pave the way towards a placebo-controlled trial that could clarify the role of CRP in cardiovascular disease.

    China has the world's highest diabetes prevalence, which along with hypertension and inflammation continues to grow particularly among children. Little is known about the strength of the association of these cardiometabolic risk factors between parents and their children; thus, the potential of household-based strategies to reduce risk is unknown. The objective of the study is to examine the parent-child association for haemoglobin A1c (HbA1c), blood pressure (BP) and C-reactive protein (CRP) in a large, geographically diverse Chinese sample. In 940 parent-child pairs (children aged 7-17 years) who participated in the 2009 China Health and Nutrition Survey, we measured each individual's HbA1c and CRP using fasting blood and BP. We used sex-specific random-effects linear regression to examine the parent-child association for these risk factors, accounting for within-family clustering. Child's HbA1c was positively associated with parental HbA1c. Beta coefficients ranged from 0.06 (95% CI 0.03-0.12) for father-daughter to 0.43 (95% CI 0.28-0.58) for mother-son pairs. We also detected a positive mother-daughter association for BP and positive father-child associations for CRP. The statistically significant parent-child association for HbA1c, BP and CRP in Chinese families suggests that household-based interventions could be useful for confronting the high rates of diabetes, hypertension and inflammation in China. © 2016 The Authors.

    Chronic inflammation is associated with elevated risk of heart disease and may be linked to oxidative stress in obesity. Our objective was to evaluate the effect of weight loss diet composition (low carbohydrate, high fat, LC or high carbohydrate, low fat, HC) on inflammation and to determine whether this was related to oxidative stress. Twenty nine overweight women, BMI 32.1 +/- 5.4 kg/m(2), were randomly assigned to a self-selected LC or HC diet for 4 wks. Weekly group sessions and diet record collections helped enhance compliance. Body weight, markers of inflammation (serum interleukin-6, IL-6; C-reactive protein, CRP) oxidative stress (urinary 8-epi-prostaglandin F2alpha, 8-epi) and fasting blood glucose and free fatty acids were measured weekly. The diets were similar in caloric intake (1357 kcal/d LC vs. 1361 HC, p=0.94), but differed in macronutrients (58, 12, 30 and 24, 59, 18 for percent of energy as fat, carbohydrate, and protein for LC and HC, respectively). Although LC lost more weight (3.8 +/- 1.2 kg LC vs. 2.6 +/- 1.7 HC, p=0.04), CRP increased 25%; this factor was reduced 43% in HC (p=0.02). For both groups, glucose decreased with weight loss (85.4 vs. 82.1 mg/dl for baseline and wk 4, p<0.01), while IL-6 increased (1.39 to 1.62 pg/mL, p=0.04). Urinary 8-epi varied differently over time between groups (p<0.05) with no consistent pattern. Diet composition of the weight loss diet influenced a key marker of inflammation in that LC increased while HC reduced serum CRP but evidence did not support that this was related to oxidative stress.

    The aim of this study was to evaluate whether pregnant women with fetal growth restriction (FGR) have higher plasma neopterin and C-reactive protein (CRP) concentrations compared with those with uncomplicated pregnancy. A total of 34 pregnant women with FGR and 62 patients with uncomplicated pregnancy were included. Neopterin and CRP levels were measured at the time of diagnosis. The primary outcome of this study was to compare the neopterin and CRP levels in pregnant women with FGR and those with uncomplicated pregnancies. The secondary outcome of our study was to evaluate the correlation between fetal birth weight and maternal neopterin levels. The serum neopterin levels were significantly elevated in pregnant women with FGR (22.71 ± 7.70 vs 19.15 ± 8.32). However, CRP was not elevated in pregnant women with FGR (7.47 ± 7.59 vs 5.29 ± 3.58). These findings support the hypothesis that pregnancy with FGR is associated with a marked increase in macrophage activation and the natural immune system.

  10. Relationship of C-reactive protein, metabolic syndrome and diabetes mellitus: potential role of statins.

    2005-12-01

    Atherosclerosis and the metabolic derangements of insulin resistance, metabolic syndrome and diabetes mellitus are all associated with underlying inflammatory processes. C-reactive protein (CRP), a marker of inflammation, has been shown to be a strong independent predictor of vascular events. It adds to cardiovascular disease risk at all levels of low-density-lipoprotein cholesterol and Framingham risk scores, and elevated levels are also associated with increasing severity of the metabolic syndrome. The development of a simple, stable, noninvasive test to measure high-sensitivity CRP has provided a clinical tool that may have an important role in the identification and assessment of individuals likely to develop cardiovascular or metabolic disease. The role of CRP in predicting cardiovascular risk is less clear in African Americans, however, than in white populations. Statins and thiazolidinediones are being investigated for their potential role in the prevention and treatment of the inflammatory processes involved in the metabolic syndrome and cardiovascular disease. In the future, assessment of CRP levels may contribute importantly to clinical decision-making in reducing cardiovascular risk.

    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.

    There is uncertainty about the optimal teicoplanin regimens for neonates. The study aim was to determine the population pharmacokinetics (PK) of teicoplanin in neonates, evaluate currently recommended regimens and explore the exposure-effect relationships. An open-label PK study was conducted. Neonates from 26 to 44 weeks post-menstrual age were recruited (n = 18). The teicoplanin regimen was a 16 mg/kg loading dose, followed by 8 mg/kg once daily. Therapeutic drug monitoring and dose adjustment were not conducted. A standard two-compartment PK model was developed, followed by models that incorporated weight. A PK/pharmacodynamic (PD) model with C-reactive protein serial measurements as the PD input was fitted to the data. Monte Carlo simulations (n = 5000) were performed using Pmetrics. The AUCs at steady state and the proportion of patients achieving the recommended drug exposures (i.e. C min >15 mg/L) were determined. The study was registered in the European Clinical Trials Database Registry (EudraCT: 2012-005738-12). The PK allometric model best accounted for the observed data. The PK parameters medians were: clearance = 0.435 × (weight/70) 0.75 (L/h); volume = 0.765 (L); K cp  = 1.3 (h -1 ); and K pc  = 0.629 (h -1 ). The individual time-course of C-reactive protein was well described using the Bayesian posterior estimates for each patient. The simulated median AUC 96-120 was 302.3 mg·h/L and the median C min at 120 h was 12.9 mg/L; 38.8% of patients attained a C min >15 mg/L by 120 h. Teicoplanin population PK is highly variable in neonates, weight being the best descriptor of PK variability. A low percentage of neonates were able to achieve C min >15 mg/L. The routine use of therapeutic drug monitoring and improved knowledge on the PD of teicoplanin is required. © The Author 2016.

    To investigate the usefulness of procalcitonin (PCT) and other analytical parameters (white blood cell count [WBC], C-reactive protein [CRP]) as markers of acute renal damage in children after a first febrile or afebrile urinary tract infection (UTI). A retrospective study was conducted on children with a first episode of UTI admitted between January 2009 to December 2011, and in whom serum PCT, CRP and white blood cell count were measured, as well as assessing the acute renal damage with renal scintigraphy with 99m Tc-DMSA (DMSA) within the first 72h after referral. A descriptive study was performed and ROC curves were plotted, with optimal cut-off points calculated for each parameter. The 101 enrolled patients were divided into two groups according to DMSA scintigraphy results, with 64 patients being classified with acute pyelonephritis (APN), and 37 with UTI. The mean WBC, CRP and PCT values were significantly higher in patients with APN with respect to normal acute DMSA. The area under the ROC curve was 0.862 for PCR, 0.774 for WBC, and 0.731 for PCT. The optimum statistical cut-off value for PCT was 0.285ng/ml (sensitivity 71.4% and specificity 75%). Although the mean levels of fever, WBC, CRP, and PCT were significantly increased in patients with APN than in those who had UTI, the sensitivity and specificity of these analytical parameters are unable to predict the existence of acute renal damage, making the contribution by renal DMSA scintigraphy essential.

    2012-01-01

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

    Objective We sought to understand the link between low SEP and cardiovascular disease (CVD) by examining the association between SEP, health-related coping behaviors, and C-reactive protein (CRP), an inflammatory marker and independent risk factor for CVD in a US sample of adults. Design We used a multiple mediation model to evaluate how these behaviors work in concert to influence CRP levels and whether these relationships were moderated by gender and race/ethnicity. Main outcome measures CRP levels were divided into two categories: elevated CRP (3.1–10.0 mg/L) and normal CRP (≤ 3.0 mg/L). Results Both poverty and low educational attainment were associated with elevated CRP, and these associations were primarily explained through higher levels of smoking and lower levels of exercise. In the education model, poor diet also emerged as a significant mediator. These behaviors accounted for 87.9% of the total effect of education on CRP and 55.8% the total effect of poverty on CRP. We also found significant moderation of these mediated effects by gender and race/ethnicity. Conclusion These findings demonstrate the influence of socioeconomically-patterned environmental constraints on individual-level health behaviors. Specifically, reducing socioeconomic inequalities may have positive effects on CVD disparities through reducing cigarette smoking and increasing vigorous exercise. PMID:20496985

    C-reactive protein (CRP) is a sensitive marker for inflammation in people and dogs. In people, an association between CRP concentration and atherosclerosis has been reported. Atherosclerosis is rare in dogs, but the Miniature Schnauzer breed may be at increased risk for developing this vascular disease. It is not known if CRP concentrations in Miniature Schnauzer dogs differ from those in other dog breeds. Our objectives were to validate an automated human CRP assay for measuring CRP in dogs and compare CRP concentrations in healthy Miniature Schnauzer dogs with those in non-Miniature Schnauzer breeds. Sera from 37 non-Miniature Schnauzer dogs with inflammatory disease were pooled and used to validate a human CRP immunoturbidimetric assay for measuring canine CRP. Blood was collected from 20 healthy Miniature Schnauzer dogs and 41 healthy dogs of other breeds. Median serum CRP concentration of healthy Miniature Schnauzer dogs was compared with that of healthy non-Miniature Schnauzer dogs. The human CRP assay measured CRP reliably with linearity between 0 and 20 mg/L. CRP concentration for healthy Miniature Schnauzer dogs (median 4.0 mg/L, minimum-maximum 0-18.2 mg/L) was significantly higher than for the healthy non-Miniature Schnauzer dogs (median 0.1 mg/L, minimum-maximum 0-10.7 mg/L); 17 of the 20 Miniature Schnauzer dogs had values that overlapped with those of the non-Miniature Schnauzer dogs. Median CRP concentration of Miniature Schnauzer dogs was slightly higher than that of other breeds of dogs. A relationship between higher CRP concentration in Miniature Schnauzer dogs and idiopathic hyperlipidemia, pancreatitis, and possible increased risk for atherosclerosis remains to be determined. ©2011 American Society for Veterinary Clinical Pathology.

To assess relationship of high sensitivity C reactive protein (hsCRP level in pts with antiphospholipid syndrome (APS with clinico-laboratory features and cardiovascular pathology. Material and methods. 206 pts were included. 58 from them had primary APS (PAPS, 72 –systemic lupus erythematosus (SLE with APS and 76 – SLE. 29 from 76 pts of the latter group were positive on anticardiolipin antibodies (ACA – SLE with antiphospholipid antibodies (APhL and 47 – low positive or negative on ACA – SLE without APhL. 72 persons without autoimmune diseases were included into control group. CRP (with high sensitivity immuno-nephelometric assay, APhL (with solid phase immuno-enzyme assay, plasma lipids were evaluated, sonography with measurement of intima-media complex (IMC thickness of common carotid arteries, carotid artery bulbs and internal carotid arteries, electrocardiography (ECG, echocardiography (EchoCG, Holter ECG monitoring were performed. Results. HsCRP serum level in pts was significantly higher than in control: 2,55 [0,71; 7,04] mg/l (varied from 0,15 to 39,85 vs 0,68 [0,26; 1,97] mg/l (varied from 0,1 to 9,61, p<0,001. Most high hsCRP concentration was found in SLE with APS (p=0,02. HsCRP level in pts with PAPS with history of combined or isolated arterial thrombosis was significantly higher than in pts with SLE and APS having the same localization of thrombosis. HsCRP concentration less than 3 mg/l correlated with duration of postthrombotic period in pts with PAPS. HsCRP level also correlated with triglyceride concentration, body mass index, summated coronary risk and magistral arteries IMC thickness. Conclusion. HsCRP elevation in pts with APS was associated with development of combined and arterial thrombosis as well as with traditional risk factors of atherosclerosis.

    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 C-reactive Protein (CRP measurements above 10 mg/L have been conventionally treated as acute inflammation and excluded from epidemiologic studies of chronic inflammation. However, recent evidence suggest that such CRP elevations can be seen even with chronic inflammation. The authors assessed 3,300 participants in The Coronary Artery Risk Development in Young Adults study, who had two or more CRP measurements between 1992/3 and 2005/6 to a investigate characteristics associated with repeated CRP elevation above 10 mg/L; b identify subgroups at high risk of repeated elevation; and c investigate the effect of different CRP thresholds on the probability of an elevation being one-time rather than repeated. 225 participants (6.8% had one-time and 103 (3.1% had repeated CRP elevation above 10 mg/L. Repeated elevation was associated with obesity, female gender, low income, and sex hormone use. The probability of an elevation above 10 mg/L being one-time rather than repeated was lowest (51% in women with body mass index above 31 kg/m(2, compared to 82% in others. These findings suggest that CRP elevations above 10 mg/L in obese women are likely to be from chronic rather than acute inflammation, and that CRP thresholds above 10 mg/L may be warranted to distinguish acute from chronic inflammation in obese women.

    The highly conserved SGT1 (suppressor of the G2 alleles of skp1) proteins from Arabidopsis are known to contribute to plant resistance to pathogens. While SGT1 proteins respond to fungal pathogens, their antifungal activity is not reported and the mechanism for this inhibition is not well understood. Therefore, recombinant Arabidopsis SGT1 proteins were cloned, expressed, and purified to evaluate their antifungal activity, resulting in their potent inhibition of pathogen growth. Dye-labeled proteins are localized to the cytosol of Candida albicans cells without the disruption of the cell membrane. Moreover, we showed that entry of the proteins into C. albicans cells resulted in the accumulation of reactive oxygen species (ROS) and cell death via altered mitochondrial potential. Morphological changes of C. albicans cells in the presence of proteins were visualized by scanning electron microscopy. Our data suggest that AtSGT1 proteins play a critical role in plant resistance to pathogenic fungal infection and they can be classified to a new plant antifungal protein.

    Human C-reactive protein (CRP) is an acute phase reactant involved in chronic and acute inflammation. CRP is associated with metabolic syndrome, obesity, atherosclerosis, unstable angina, insulin resistance and diabetes. The present study evaluates the association of + 1059 G>C silent polymorphism in exon 2 of CRP gene in 581 cases [CAD (206), T2D (266), T2D with CAD (109)] and 235 controls in the population of Punjab (North-West India). The frequency of + 1059 G allele is highest in CAD (98.3%) followed by T2D (98.1%), T2D + CAD cases (97.7%) and controls (94.7%). G-allele is associated with increased risk of T2D [P = 0.003, OR = 2.93 (1.39-6.17)] and CAD [P = 0.004, OR = 3.25 (1.39-7.60)] in comparison to controls. Recessive model shows that GG genotype increases the risk of CAD by 4 fold (P = 0.003, OR = 4.19, 1.62-10.80), T2D by 3 fold (P = 0.008, OR = 3.23, 1.36-7.60) and T2D + CAD by 3.5 fold (P = 0.029, OR = 3.64, 1.14-11.66). Factor analyses show that BMI, WC, and WHR are core predictors for CAD and T2D, whereas CHO, TG and VLDL for T2D + CAD. The present study concludes that GG genotype of CRP + 1059 G>C polymorphism and clustering of obesity and dyslipidemia underlie the risk towards CAD, T2D and T2D + CAD in the North-West Indian population of Punjab.

    Increased levels of C-reactive protein (CRP) have been considered as a marker in assessing neurogenic inflammation of migraine patients. An inverse relationship between serum bilirubin and CRP has been observed in various diseases. Therefore, we analyzed serum bilirubin levels in migraine patients, and investigated the relationship between serum bilirubin and CRP in migraineurs. A total of 86 newly diagnosed migraine patients were consecutively recruited to this study. Significantly lower median serum total bilirubin, conjugated bilirubin (CB) and unconjugated bilirubin were found in patients with migraine than healthy controls, and the levels of CRP were significantly higher in migraine patients than healthy controls. A negative correlation between CRP and CB was observed in patients with migraine (r = -0.255, P = 0.018). In a multiple linear regression model, the concentrations of CRP remained negatively correlated with CB. Our study demonstrates that serum bilirubin concentrations are decreased in migraineurs, and CB levels were found to be positively correlated with CRP in migraine patents. However, larger cross-sectional and prospective studies are needed to establish whether serum bilirubin may be a useful biomarker for assessing neurogenic inflammation in migraine patients and eventually guiding the therapy. © 2016 Wiley Periodicals, Inc.

    Full Text Available Elevation in C-reactive protein (CRP levels have been shown in patients with aortic valve stenosis (AS. Minor allele of the CRP gene (CRP rs1205 C>T polymorphism has been associated with lower plasma CRP concentrations in cohorts of healthy and atherosclerotic patients. Considering the existing similarities between atherosclerosis and AS, we examined the effect of CRP rs1205 C>T polymorphism on the AS severity. Three hundred consecutive Caucasian patients diagnosed with AS were genotyped for the rs1205 C>T polymorphism using the TaqMan assay. Severity of the AS was assessed using transthoracic echocardiography. The degree of calcification was analyzed semi-quantitatively. Carriers of the rs1205 T allele were characterized by elevated serum CRP levels (2.53 (1.51–3.96 vs. 1.68 (0.98–2.90 mg/L, p < 0.001 and a higher proportion of the severe aortic valve calcification (70.4% vs. 55.1%, p = 0.01 compared with major homozygotes. The effect of CRP rs1205 polymorphism on CRP levels is opposite in AS-affected than in unaffected subjects, suggesting existence of a disease-specific molecular regulatory mechanism. Furthermore, rs1205 variant allele predisposes to larger aortic valve calcification, potentially being a novel genetic risk marker of disease progression.

    2012-12-01

    Full Text Available 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 Abstract Background The toxic effects of many simple organic compounds stem from their biotransformation to chemically reactive metabolites which bind covalently to cellular proteins. To understand the mechanisms of cytotoxic responses it may be important to know which proteins become adducted and whether some may be common targets of multiple toxins. The literature of this field is widely scattered but expanding rapidly, suggesting the need for a comprehensive, searchable database of reactive metabolite target proteins. Description The Reactive Metabolite Target Protein Database (TPDB is a comprehensive, curated, searchable, documented compilation of publicly available information on the protein targets of reactive metabolites of 18 well-studied chemicals and drugs of known toxicity. TPDB software enables i string searches for author names and proteins names/synonyms, ii more complex searches by selecting chemical compound, animal species, target tissue and protein names/synonyms from pull-down menus, and iii commonality searches over multiple chemicals. Tabulated search results provide information, references and links to other databases. Conclusion The TPDB is a unique on-line compilation of information on the covalent modification of cellular proteins by reactive metabolites of chemicals and drugs. Its comprehensiveness and searchability should facilitate the elucidation of mechanisms of reactive metabolite toxicity. The database is freely available at http://tpdb.medchem.ku.edu/tpdb.html

    In this paper, we propose an AlGaN/GaN high electron mobility transistor (HEMT)-based biosensor for the detection of C-reactive protein (CRP) using a null-balancing circuit. A null-balancing circuit was used to measure the output voltage of the sensor directly. The output voltage of the proposed biosensor was varied by antigen-antibody interactions on the gate surface due to CRP charges. The AlGaN/GaN HFET-based biosensor with null-balancing circuit applied shows that CRP can be detected in a wide range of concentrations, varying from 10 ng/mL to 1000 ng/mL. X-ray photoelectron spectroscopy was carried out to verify the immobilization of self-assembled monolayer with Au on the gated region.

  14. Activated protein C attenuates acute ischaemia reperfusion injury in skeletal muscle.

    Activated protein C (APC) is an endogenous anti-coagulant with anti-inflammatory properties. The purpose of the present study was to evaluate the effects of activated protein C in the setting of skeletal muscle ischaemia reperfusion injury (IRI). IRI was induced in rats by applying rubber bands above the levels of the greater trochanters bilaterally for a period of 2h followed by 12h reperfusion. Treatment groups received either equal volumes of normal saline or activated protein C prior to tourniquet release. Following 12h reperfusion, muscle function was assessed electrophysiologically by electrical field stimulation. The animals were then sacrificed and skeletal muscle harvested for evaluation. Activated protein C significantly attenuated skeletal muscle reperfusion injury as shown by reduced myeloperoxidase content, wet to dry ratio and electrical properties of skeletal muscle. Further in vitro work was carried out on neutrophils isolated from healthy volunteers to determine the direct effect of APC on neutrophil function. The effects of APC on TNF-alpha stimulated neutrophils were examined by measuring CD18 expression as well as reactive oxygen species generation. The in vitro work demonstrated a reduction in CD18 expression and reactive oxygen species generation. We conclude that activated protein C may have a protective role in the setting of skeletal muscle ischaemia reperfusion injury and that this is in part mediated by a direct inhibitory effect on neutrophil activation.

    The use of cardiopulmonary bypass (CPB) can cause changes in serum creatinine and cystatin C independent of glomerular filtration rate. We aimed to quantify the temporal changes of these biomarkers and C-reactive protein (CRP) after CPB. This was a prospective study at an academic medical centre between April and October 2013. We compared postoperative changes in serum creatinine and cystatin C in 38 patients with normal preoperative kidney function who underwent cardiac surgery using CPB and did not develop perioperative acute kidney injury (AKI). The effect of inflammation on intra-individual changes was examined in mixed effects regressions, using measurements of pre- and postoperative CRP. Both serum creatinine (79.9 ± 22.7 vs. 92.6 ± 21.4 µmol/L, P = 0.001) and cystatin C (1.16 ± 0.39 vs. 1.33 ± 0.37 mg/L, P = 0.012) decreased significantly in the first 8 h postoperatively compared to preoperatively, as a result of haemodilution. Thereafter serum creatinine returned to preoperative levels, whereas serum cystatin C continued to rise and was significantly elevated at 72 h post-CPB compared to preoperative levels (1.53 ± 0.48 vs. 1.33 ± 0.37 mg/L, P = 0.003). CRP levels increased significantly post-CPB and were significantly associated with increases in both serum creatinine and cystatin C. Serum creatinine and cystatin C appear not to be interchangeable biomarkers during and immediately after CPB. Processes unrelated to kidney function such as acute inflammation have a significant effect on post-CPB changes in these biomarkers, and may result in significant increases in serum cystatin C that could erroneously be interpreted as AKI. © 2015 Asian Pacific Society of Nephrology.

    Full Text Available C-reactive protein is a powerful independent predictor of cardiovascular events in patients with coronary artery disease. The relation between C-reactive protein (CRP concentration and in-hospital outcome, after coronary artery bypass grafting (CABG, has not yet been established. The study aims to evaluate the predictive value of pre-operative CRP for in-hospital cardiovascular events after CABG surgery. High-sensitivity CRP (hs-CRP levels were measured pre-operatively on the day of surgery in 66 patients scheduled for elective on pump CABG surgery. Post-operative cardiovascular events such as death from cardiovascular causes, ischemic stroke, myocardial damage, myocardial infarction and low output heart failure were recorded. During the first 30 days after surgery, 54 patients were free from observed events and 14 developed the following cardiovascular events: 10 (15% had myocardial damage, four (6% had low output heart failure and two (3% suffered stroke. No patients died during the follow-up period. Serum concentration of hs-CRP ≥ 3.3 mg/l (cut-off point obtained by ROC analysis was related to higher risk of post-operative cardiovascular events (36% vs 6%, P = 0.01, myocardial damage (24% vs 6%, P = 0.04 and low output heart failure (12% vs 0%, P = 0.04. Multivariate logistic regression analysis showed that hs-CRP ≥ 3.3 mg/l ( P = 0.002, O.R.: 19.3 (95% confidence interval (CI 2.9-128.0, intra-operative transfusion of red blood cells ( P = 0.04, O.R.: 9.9 (95% C.I. 1.1-85.5 and absence of diuretics in daily antihypertensive treatment ( P = 0.02, O.R.: 15.1 (95% C.I. 1.4-160.6 were independent predictors of combined cardiovascular event. Patients having hs-CRP value greater or equal to 3.3 mg/l pre-operatively have an increased risk of post-operative cardiovascular events after on pump coronary artery bypass grafting surgery.

    Recent advances in understanding complex tumor interactions have led to the discovery of an association between inflammation and cancer, in particular for colon and lung cancer, but only a very few have dealt with oral cancer. Therefore, the aim of the current study was to investigate the significance of preoperative C-reactive protein (CRP) levels as a parameter for development of lymph node metastases or recurrence. In 278 patients with oral cancer, preoperative CRP levels were compared with development of recurrence and metastasis. In 27 patients from the normal CRP group, and in 21 patients from the elevated CRP group, local recurrence was observed. Concerning lymph node metastases, 37 patients were in the normal group and 9 patients in the elevated CRP group. No significant correlation could be found between elevated CRP levels and metastasis (p = 0.468) or recurrence (p = 0.137). Our findings do not appear to support a correlation between preoperative CRP levels and development of recurrence or metastases. In further studies, CRP levels in precancerous lesions and in Human Papilloma Virus (HPV) positive patients with oral squamous cell carcinoma (SCC) should be studied.

    Full Text Available Background. Since high sensitivity C-reactive protein (hsCRP is predictive of cardiovascular events, it is important to examine the relationship between hsCRP and other inflammatory and oxidative stress markers linked to cardiovascular disease (CVD etiology. Previously, we reported that hsCRP induces the oxidative stress adduct 8-oxo-7,8-dihydro-2′deoxyguanosine (8-oxodG and that these markers are significantly associated in women. Recent data indicates that brain-derived neurotrophic factor (BDNF may have a role in CVD. Methods and Results. We examined BDNF levels in 3 groups of women that were age- and race-matched with low (3–20 mg/L, and high (>20 mg/L hsCRP (n=39 per group and found a significant association between hsCRP, BDNF, and 8-oxodG. In African American females with high hsCRP, increases in BDNF were associated with decreased serum 8-oxodG. This was not the case in white women where high hsCRP was associated with high levels of BDNF and high levels of 8-oxodG. BDNF treatment of cells reduced CRP levels and inhibited CRP-induced DNA damage. Conclusion. We discovered an important relationship between hsCRP, 8-oxodG, and BDNF in women at hsCRP levels >3 mg/L. These data suggest that BDNF may have a protective role in counteracting the inflammatory effects of hsCRP.

    To (1) measure C-reactive protein (CRP) and high mobility group box 1 (HMGB1) and (2) evaluate their prognostic value and relationship to severity of systemic inflammatory response syndrome, routine hematological and acid-base parameters in dogs with gastric dilatation volvulus (GDV). Prospective observational study from September 2010 to June 2012. Veterinary teaching hospital. Forty-one client-owned dogs with GDV. None. Blood was collected before surgery (baseline), postsurgery, 6-10 hours postsurgery, and 18-22 hours postsurgery. CRP and HMGB1 were measured in all samples, and routine hematological, biochemical, and acid-base analyses were performed. Only baseline and postsurgery samples were used from nonsurvivors (n = 10). CRP increased significantly from postsurgery sampling to 18-22 hours postsurgery, while HMGB1 did not change over time. There was a significant difference in HMGB1 between survivors and nonsurvivors over time. Both proteins correlated with systemic inflammatory response syndrome severity, total leukocyte, segmented neutrophils, and band counts. HMGB1 correlated also with acid-base parameters (pH, bicarbonate, base excess). HMGB1 and CRP behaved differently in regards to their kinetic patterns, with HMGB1 appearing to better reflect the severity of tissue injury in dogs with GDV than CRP. © Veterinary Emergency and Critical Care Society 2015.

    Full Text Available Introduction: Factors of cardiovascular risk (CVR are often grouped in cases with diabetes mellitus (DM with significant increasment of risk for CV disease . The aim of this research is to determine the frequency of CVR and and total CVR in cases with DM and to investigate connection of CRP of other factors of CVR in total cardiovascular risks. Material and methods: In 92 cases with DM weist values were taken as well as body mass index (BMI, blood pressure, sugar in blood, cholesterol, triglycerides, C reactive protein (CRP and according to SCORE system the 10 year period of CVR were determined. Results: Out of 92 tested cases with age 55,22± 8,3 years, 63,05% were males and 36,95% were women, 81,5% were with values of sugar in blood >7mmol/l, 44,6% were with values of HbA1C>7% and 63,0% >6,5%. The value of cholesterol were >4,5mmol/l in 87%, triglycerides >1,7mmol/l in 78.3% of tested cases. 81,5% of tested cases were overweight and 49% with larger weight values. Average cardiovascular factor according to SCORE system was 3, 92± 3,7% with significant difference among sexes (M-4,86; W-2,32, p3mg/l 52% of tested cases were with high cardiovascular risk. There is significant positive correlation between CRP and cholesterol level (p<0, 01, triglycerides, blood in sugar, HbA1c and upper values of blood pressure (p<0, 05. Significant correlation between CRP and total cardiovascular risk (p=0, 63 was not evident. Conclusion: Cases with diabetes mellitus have high level of non regulated cardiovascular risk factors. Even though there is significant correlation between CRP and and pressure values, sugar in blood, HbA1c, cholesterol, triglycerides, significant correlation between CRP and total cardiovascular risk in cases with diabetes mellitus is not evident.

  2. Time variability of C-reactive protein: implications for clinical risk stratification.

    Peter Bogaty

    Full Text Available C-reactive protein (CRP is proposed as a screening test for predicting risk and guiding preventive approaches in coronary artery disease (CAD. However, the stability of repeated CRP measurements over time in subjects with and without CAD is not well defined. We sought to determine the stability of serial CRP measurements in stable subjects with distinct CAD manifestations and a group without CAD while carefully controlling for known confounders.We prospectively studied 4 groups of 25 stable subjects each 1 a history of recurrent acute coronary events; 2 a single myocardial infarction ≥7 years ago; 3 longstanding CAD (≥7 years that had never been unstable; 4 no CAD. Fifteen measurements of CRP were obtained to cover 21 time-points: 3 times during one day; 5 consecutive days; 4 consecutive weeks; 4 consecutive months; and every 3 months over the year. CRP risk threshold was set at 2.0 mg/L. We estimated variance across time-points using standard descriptive statistics and Bayesian hierarchical models.Median CRP values of the 4 groups and their pattern of variability did not differ substantially so all subjects were analyzed together. The median individual standard deviation (SD CRP values within-day, within-week, between-weeks and between-months were 0.07, 0.19, 0.36 and 0.63 mg/L, respectively. Forty-six percent of subjects changed CRP risk category at least once and 21% had ≥4 weekly and monthly CRP values in both low and high-risk categories.Considering its large intra-individual variability, it may be problematic to rely on CRP values for CAD risk prediction and therapeutic decision-making in individual subjects.

    BACKGROUND: Low-grade chronic inflammation is a characteristic feature of obesity, the most important lifestyle risk factor for hypertension. Elevated plasma concentrations of the inflammatory biomarker C-reactive protein (CRP) are associated with an increased risk of hypertension, but elevated...... plasma CRP concentrations are also closely associated with obesity. It is uncertain whether CRP is directly involved in the pathogenesis of hypertension or is only a marker of other pathogenic processes closely related to obesity. METHODS: We studied 103 obese men (body mass index (BMI) ≥ 30.0 kg/m(2......)); 63 of these men had 24-hour ambulatory blood pressure (ABP) ≥ 130/80 mm Hg and comprised the obese hypertensive (OHT) group. The 40 remaining obese men had 24-hour ABP obese normotensive (ONT) group. Our control group comprised 27 lean normotensive (LNT) men. All...

    Obesity has been linked with elevated levels of C-reactive protein (CRP), and both have been associated with increased risk of mortality and cardiovascular disease (CVD). Previous studies have used a single 'baseline' measurement and such analyses cannot account for possible changes in these which...... may lead to a biased estimation of risk. Using four cohorts from CHANCES which had repeated measures in participants 50 years and older, multivariate time-dependent Cox proportional hazards was used to estimate hazard ratios (HR) and 95 % confidence intervals (CI) to examine the relationship between......, they may participate in distinct/independent pathways. Accounting for independent changes in risk factors over time may be crucial for unveiling their effects on mortality and disease morbidity....

    C-reactive protein (CRP) is a major acute-phase protein in dogs. Serum concentrations are low in healthy animals, but increase rapidly after inflammatory stimuli. The aim of the study was to investigate CRP concentrations in various respiratory diseases of dogs and to determine if CRP can be used as a biomarker in the diagnosis of bacterial respiratory diseases. A total of 106 privately owned dogs with respiratory diseases (17 with bacterial tracheobronchitis [BTB], 20 with chronic bronchitis [CB], 20 with eosinophilic bronchopneumopathy [EBP], 12 with canine idiopathic pulmonary fibrosis [CIPF], 15 with cardiogenic pulmonary edema [CPE], and 22 with bacterial pneumonia [BP]) and 72 healthy controls. The study was conducted as a prospective cross-sectional observational study. CRP was measured in serum samples. Diagnosis was confirmed by clinical and laboratory findings, diagnostic imaging, and selected diagnostic methods such as cytological and microbiological analysis of respiratory samples, echocardiography, and histopathology. Dogs with BP had significantly higher CRP concentrations (median, 121 mg/L; interquartile range, 68-178 mg/L) than dogs with BTB (23, 15-38, P = .0003), CB (13, 8-14, P < .0001), EBP (5, 5-15, P < .0001), CIPF (17, 10-20, P < .0001), or CPE (19, 13-32, P < .0001) and healthy controls (14, 8-20, P < .0001). Dogs with BTB had significantly higher CRP concentrations than dogs with CB (P = .001) or EBP (P < .0001) and healthy controls (P = .029). These results indicate that CRP has potential for use as an additional biomarker, especially in the diagnostics of BP. Copyright © 2013 by the American College of Veterinary Internal Medicine.

    To evaluate the effects of perioperative oral administration of carprofen and meloxicam on concentrations of 3 acute-phase proteins in dogs undergoing elective ovariohysterectomy (OVH). 18 healthy adult anestrous female dogs undergoing elective OVH. Dogs were allocated to 3 groups (6 dogs/group). A placebo treatment, carprofen (2.0 mg/kg), or meloxicam (0.2 mg/kg) was orally administered to the dogs of the respective groups. The initial doses were administered 30 minutes before premedication prior to OVH; additional doses were administered once daily for 4 days after surgery. Blood samples were collected 45 minutes before premedication and 4, 8, 12, 24, 36, 48, 72, 96, and 120 hours after the end of OVH; samples were used for measurement of total WBC and neutrophil counts and concentrations of C-reactive protein (CRP), ceruloplasmin, and fibrinogen. Values did not differ significantly among groups for WBC and neutrophil counts, serum concentrations of CRP and ceruloplasmin, and plasma concentrations of fibrinogen. Concentrations of all inflammatory markers, except serum ceruloplasmin, increased significantly following OVH, but in a similar manner for each group. No significant changes were detected in serum ceruloplasmin concentrations over time. Perioperative administration of both carprofen and meloxicam did not significantly affect the concentrations of CRP, ceruloplasmin, and fibrinogen in dogs undergoing OVH. Thus, use of carprofen or meloxicam should not affect clinical interpretation of results for these 3 acute-phase proteins.

    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.

    INTRODUCTION: The diagnosis of bacterial infections in patients with solid tumours can be difficult as both the tumour and its treatment can cause symptoms and signs similar to those of infections. Many patients with solid tumours therefore receive antibiotic treatment without having a bacterial......, but with no signs of infection. RESULTS: Of the 41 admitted patients, 25 were classified as having an infection (either microbiologically or radioo-gically verified). Among the 25 cases with infection, PCT was within the normal range in 11 cases and only elevated in 14. As nearly half of the patients with infection...... had PCT within the normal range, PCT is not suited to exclude an infection. CRP was elevated in 20 patients out of the 25. CONCLUSION: PCT within the normal range cannot exclude an infection and does not appear to be superior to CRP to exclude an infection in patients with solid tumours. FUNDING...

    Full Text Available BACKGROUND Sepsis refers to the systemic response to serious infection. It can be response to the infection caused by any class of microorganism. The presence of bacteraemia is an indicator of disseminated infection and generally indicates a poorer prognosis when associated with localised disease. This study was undertaken to study the diagnostic and prognostic value of Procalcitonin (PCT in patients with sepsis. AIM To study the diagnostic and prognostic value of Procalcitonin (PCT in patients with sepsis. MATERIALS AND METHODS Fifty patients of age more than 18 years with sepsis admitted in KMC Hospitals, Mangalore, from August 2008 to June 2010 were subjects in the study after due permission from institution and informed consent from the patients. Diagnosis of sepsis was made according to criteria by ACCP/SCCM definition for sepsis. Definitive aetiological diagnosis requires isolation of microorganism from the blood and local site of infection, Gram stain and culture of the material from the primary site of infection for the microbial aetiology was taken. Other appropriate laboratory investigations depending upon requirement were done as mentioned in the investigations. RESULTS Out of total 50 patients, 23 patients were in group of sepsis, 14 were in group of severe sepsis while 13 had septic shock. Maximum number of the study patients were in the age group of 51-60 years. 52% of the study patients were male and 48% were female. Most common symptom in patients with sepsis was fever. Most common sign in the patient with sepsis is tachycardia followed by high temperature and then tachypnoea. Most common source of sepsis was respiratory infection followed by UTI. CONCLUSION Our data suggest the possibility that the addition of Procalcitonin into the standard workup of critically ill patients with suspected sepsis could increase diagnostic certainty and improve patient management.

    Full Text Available Background: Inflammation plays a pivotal role in the formation and progression of ischemic stroke. Recently, more and more epidemiological studies have focused on the association between C-reactive protein (CRP −717A > G and −286C > T > A genetic polymorphisms and ischemic stroke. However, the findings of these researches are not conclusive. Methods: We performed a meta-analysis to determine whether these two polymorphisms are associated with the risk of ischemic stroke. Eligible studies were identified from the database of PubMed, Medline, Embase, Web of Science, CNKI, Weipu, and Wanfang. We calculated odds ratios (ORs with 95% confidence intervals (CIs to assess the strength of the association. Results: Four articles were included in our study, including 1926 cases and 2678 controls for −717A > G polymorphism, 652 cases and 1103 controls for −286C > T > A polymorphism. The results of meta-analysis showed that single nucleotide polymorphism (SNP −717A > G was not significantly associated with the risk of ischemic stroke (GG vs. AA, OR = 1.12, 95% CI = 0.83-1.50, P = 0.207; GG + GA vs. AA, OR = 1.04, 95% CI = 0.93-1.17, P = 0.533; GG vs. GA + AA, OR = 1.10, 95% CI = 0.82-1.47, P = 0.220. Meta-analysis of SNP − 286C > T > A also demonstrated no statistical evidence of a significant association with the risk of ischemic stroke (AA vs. CC, OR = 0.86, 95% CI = 0.59-1.25, P = 0.348; AA vs. CC, OR = 0.92, 95% CI = 0.80-1.06, P = 0.609; AA vs. CC, OR = 0.89, 95% CI = 0.62-1.30, P = 0.374. Conclusions: This meta-analysis demonstrated little evidence to support a role of CRP gene −717A > G, −286C > T > A polymorphisms in ischemic stroke predisposition. However, to draw comprehensive and more reliable conclusions, further larger studies are needed to validate the association between CRP gene polymorphisms and ischemic stroke in various ethnic groups.

    Full Text Available In this paper, we propose an AlGaN/GaN high electron mobility transistor (HEMT-based biosensor for the detection of C-reactive protein (CRP using a null-balancing circuit. A null-balancing circuit was used to measure the output voltage of the sensor directly. The output voltage of the proposed biosensor was varied by antigen-antibody interactions on the gate surface due to CRP charges. The AlGaN/GaN HFET-based biosensor with null-balancing circuit applied shows that CRP can be detected in a wide range of concentrations, varying from 10 ng/mL to 1000 ng/mL. X-ray photoelectron spectroscopy was carried out to verify the immobilization of self-assembled monolayer with Au on the gated region.

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

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

    Full Text Available Whey protein, a by-product from cheese-making, is often used in a variety of food formulations due to its unsurpassednutritional quality and inherent functional properties. However, the possibilities for the improvement and upgrading of wheyprotein utilization still need to be explored. Reactive supercritical fluid extrusion (SCFX is a novel technique that has beenrecently reported to successfully functionalize commercially available whey proteins into a product with enhanced functionalproperties. The specific goal of this review is to provide fundamental understanding of the reinforcement mechanism andprocessing of protein functionalization by reactive SCFX process. The superimposed extrusion variables and their interactionmechanism affect the physico-chemical properties of whey proteins. By understanding the structure, functional properties andprocessing relationships of such materials, the rational design criteria for novel functionalized proteins could be developedand effectively utilized in food systems.

    Inflammation is suggested to be a central feature of atherosclerosis, particularly among smokers. We studied whether inflammatory biomarkers GlycA and high-sensitivity C-reactive protein are associated with cigarette smoking. A total of 11 509 participants, 6774 from the MESA (Multi-Ethnic Study of Atherosclerosis) and 4735 from ELSA-Brasil (The Brazilian Longitudinal Study of Adult Health) were included. We evaluated the cross-sectional association between multiple measures of smoking behavior and the inflammatory biomarkers, GlycA and high-sensitivity C-reactive protein, using regression models adjusted for demographic, anthropometric, and clinical characteristics. Participants were 57.7±11.1 years old and 46.4% were men. Never, former, and current smokers comprised 51.7%, 34.0%, and 14.3% of the population, respectively. Multivariable-adjusted mean absolute difference in GlycA levels (μmol/L) with 95% confidence interval (CI) were higher for former (4.1, 95% CI, 1.7-6.6 μmol/L) and current smokers (19.9, 95% CI, 16.6-23.2 μmol/L), compared with never smokers. Each 5-unit increase in pack-years of smoking was associated with higher GlycA levels among former (0.7, 95% CI, 0.3-1.1 μmol/L) and current smokers (1.6, 95% CI, 0.8-2.4 μmol/L). Among former smokers, each 5-year increase in time since quitting smoking was associated with lower GlycA levels (-1.6, 95% CI, -2.4 to -0.8 μmol/L) and each 10-unit increase in number of cigarettes/day was associated with higher GlycA among current smokers (2.8, 95% CI, 0.5-5.2 μmol/L). There were similar significant associations between all measures of smoking behavior, and both log-transformed GlycA and high-sensitivity C-reactive protein. Acute and chronic exposure to tobacco smoking is associated with inflammation, as quantified by both GlycA and high-sensitivity C-reactive protein. These biomarkers may have utility for the study and regulation of novel and traditional tobacco products. © 2017 The Authors

    Serum C-reactive protein (CRP) increases and albumin decreases in patients with inflammation and infection. However, their role in patients with acute pancreatitis is not clear. The present study was to investigate the predictive significance of the CRP/albumin ratio for the prognosis and mortality in acute pancreatitis patients. This study was performed retrospectively with 192 acute pancreatitis patients between January 2002 and June 2015. Ranson scores, Atlanta classification and CRP/albumin ratios of the patients were calculated. The CRP/albumin ratio was higher in deceased patients compared to survivors. The CRP/albumin ratio was positively correlated with Ranson score and Atlanta classification in particular and with important prognostic markers such as hospitalization time, CRP and erythrocyte sedimentation rate. In addition to the CRP/albumin ratio, necrotizing pancreatitis type, moderately severe and severe Atlanta classification, and total Ranson score were independent risk factors of mortality. It was found that an increase of 1 unit in the CRP/albumin ratio resulted in an increase of 1.52 times in mortality risk. A prediction value about CRP/albumin ratio >16.28 was found to be a significant marker in predicting mortality with 92.1% sensitivity and 58.0% specificity. It was seen that Ranson and Atlanta classification were higher in patients with CRP/albumin ratio >16.28 compared with those with CRP/albumin ratio ≤16.28. Patients with CRP/albumin ratio >16.28 had a 19.3 times higher chance of death. The CRP/albumin ratio is a novel but promising, easy-to-measure, repeatable, non-invasive inflammation-based prognostic score in acute pancreatitis.

    To standardize C-reactive protein (CRP) assays, the National Metrology Institute of Japan (NMIJ) has developed a C-reactive protein solution certified reference material, CRM 6201-b, which is intended for use as a primary reference material to enable the SI-traceable measurement of CRP. This study describes the development process of CRM 6201-b. As a candidate material of the CRM, recombinant human CRP solution was selected because of its higher purity and homogeneity than the purified material from human serum. Gel filtration chromatography was used to examine the homogeneity and stability of the present CRM. The total protein concentration of CRP in the present CRM was determined by amino acid analysis coupled to isotope-dilution mass spectrometry (IDMS-AAA). To improve the accuracy of IDMS-AAA, we optimized the hydrolysis process by examining the effect of parameters such as the volume of protein samples taken for hydrolysis, the procedure of sample preparation prior to the hydrolysis, hydrolysis temperature, and hydrolysis time. Under optimized conditions, we conducted two independent approaches in which the following independent hydrolysis and liquid chromatography-isotope dilution mass spectrometry (LC-IDMS) were combined: one was vapor-phase acid hydrolysis (130 °C, 24 h) and hydrophilic interaction liquid chromatography-mass spectrometry (HILIC-MS) method, and the other was microwave-assisted liquid-phase acid hydrolysis (150 °C, 3 h) and pre-column derivatization liquid chromatography-tandem mass spectrometry (LC-MS/MS) method. The quantitative values of the two different amino acid analyses were in agreement within their uncertainties. The certified value was the weighted mean of the results of the two methods. Uncertainties from the value-assignment method, between-method variance, homogeneity, long-term stability, and short-term stability were taken into account in evaluating the uncertainty for a certified value. The certified value and the

    Serum C-reactive protein (CRP), an acute inflammatory response biomarker, has been recognized as an indicator of malignant disease progression. However, the prognostic significance of CRP levels collected before tumor removal in intrahepatic cholangiocarcinoma requires further investigation. We sampled the CRP levels in 140 patients with intrahepatic cholangiocarcinoma who underwent hepatectomies with regional lymphadenectomies between 2006 and 2013. A retrospective analysis of the clinicopathological data was performed. We focused on the impact of serum CRP on the patients’ cancer-specific survival and recurrence-free survival rates. High levels of preoperative serum CRP were significantly associated with well-established clinicopathologic features, including gender, advanced tumor stage, and elevated carcinoembryonic antigen and carbohydrate antigen 19-9 levels (P < 0.05). Univariate analysis demonstrated a significant association between high levels of serum CRP and adverse cancer-specific survival (P = 0.001) and recurrence-free survival (P < 0.001). In patients with stage I/II intrahepatic cholangiocarcinoma, the serum CRP level was a prognostic indicator for cancer-specific survival. In patients with stage I/II or stage III/IV, the serum CRP level was a prognostic indicator for recurrence-free survival (P < 0.05). Additionally, multivariate analysis identified serum CRP level in intrahepatic cholangiocarcinoma as an independent prognostic factor (P < 0.05). We confirmed a significant association of elevated pre-operative CRP levels with poor clinical outcomes for the tested patients with intrahepatic cholangiocarcinoma. Our results indicate that the serum CRP level may represent a useful factor for patient stratification in intrahepatic cholangiocarcinoma management

    We aimed to investigate the effects of febuxostat on IR and the expression of high-sensitivity C-reactive protein (hs-CRP) in patients with primary gout. Forty-two cases of primary gout patients without uric acid-lowering therapy were included in this study. After a physical examination, 20 age- and sex-matched patients were included as normal controls. The levels of fasting insulin (INS), fasting blood glucose (FBG), and hs-CRP were determined. IR was assessed using the Homeostasis Model Assessment of Insulin Resistance (HOMA-IR). Gout patients had higher levels of UA, INS, HOMA-IR, and hs-CRP than normal controls (P gout patients and implicate that febuxostat can effectively control the level of serum UA and increase insulin sensitivity in primary gout patients.

    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.

    Whey supplementation is beneficial for human health, possibly by reducing the circulating C-reactive protein (CRP) level, a sensitive marker of inflammation. Thus, a meta-analysis of randomized controlled trials was conducted to evaluate their relationship. A systematic literature search was conducted in July, 2014, to identify eligible studies. Either a fixed-effects model or a random-effects model was used to calculate pooled effects. The meta-analysis results of nine trials showed a slight, but no significant, reduction of 0.42 mg/L (95% CI −0.96, 0.13) in CRP level with the supplementation of whey protein and its derivates. Relatively high heterogeneity across studies was observed. Subgroup analyses showed that whey significantly lowered CRP by 0.72 mg/L (95% CI −0.97, −0.47) among trials with a daily whey dose ≥20 g/day and by 0.67 mg/L (95% CI −1.21, −0.14) among trials with baseline CRP ≥3 mg/L. Meta-regression analysis revealed that the baseline CRP level was a potential effect modifier of whey supplementation in reducing CRP. In conclusion, our meta-analysis did not find sufficient evidence that whey and its derivates elicited a beneficial effect in reducing circulating CRP. However, they may significantly reduce CRP among participants with highly supplemental doses or increased baseline CRP levels. PMID:25671415

    Elevated plasma C-reactive protein (CRP) is regarded as a risk predictor for cardiovascular diseases. This systematic review explored the robustness of observations that CRP is elevated in periodontitis. Similarly, the effect of periodontal therapy on CRP levels was investigated. Selection of publications was based on: (1) cross-sectional (case-control) studies; (2) longitudinal (treatment) studies; (3) high-sensitivity CRP measurement; (4) median and/or mean (+/-SD) values presented; and (5) subjects with no systemic disorders. Screening of the initially 448 identified studies and reference checking resulted in 18 suitable papers. The majority of the studies showed that CRP levels are higher in patients than in controls. Often, studies showed that patients had CRP levels >2.1 mg/l. A meta-analysis of 10 cross-sectional studies showed that the weighted mean difference (WMD) of CRP between patients and controls was 1.56 mg/l (pperiodontal therapy. Eligible treatment studies in a meta-analysis demonstrated a WMD of reductions of CRP after therapy of 0.50 mg/L (95% CI 0.08-0.93) (p=0.02). There is strong evidence from cross-sectional studies that plasma CRP in periodontitis is elevated compared with controls. There is modest evidence on the effect of periodontal therapy in lowering the levels of CRP.

    Full Text Available The prognostic role of baseline C-reactive protein (CRP in chronic obstructive pulmonary disease (COPD is controversial. In order to clarify this issue, we performed a systematic review and meta-analysis to assess the predictive effect of baseline CRP level in COPD patients. 15 eligible articles focusing on late mortality in COPD were included in our study. We performed a random-effects meta-analysis, and assessed heterogeneity and publication bias. We pooled hazard ratio (HR estimates and their 95% confidence intervals on mortality for the comparison between the study-specific highest category of CRP level versus the lowest category. In overall analysis, elevated baseline CRP levels were significantly associated with higher mortality (HR 1.53, 95% CI 1.32–1.77, I2=68.7%, p<0.001. Similar results were observed across subgroups. However, higher mortality risk was reported in studies using a cut-off value of 3 mg·L−1 (HR 1.61, 95% CI 1.12–2.30 and in those enrolling an Asiatic population (HR 3.51, 95% CI 1.69–7.31. Our analysis indicates that baseline high CRP level is significantly associated with higher late mortality in patients with COPD. Further prospective controlled studies are needed to confirm these data.

    C-reactive protein (CRP) is the prototype component of acute-phase proteins induced ultimately by interleukin (IL)-6 in the liver, but it is unknown whether periradicular tissues locally express CRP. The present study aimed to identify whether CRP messenger RNA synthesis occurs in situ within apical lesions of endodontic origin (ALEOs) and healthy periodontal ligament and its association with IL-6 and to determine their protein levels and tissue localization. Patients with asymptomatic apical periodontitis and healthy volunteers presenting at the School of Dentistry, University of Chile, Santiago, Chile, were enrolled. ALEOs and healthy teeth were obtained and processed for either immunohistochemistry and double immunofluorescence to assess IL-6 and CRP tissue localization, whereas healthy periodontal ligaments were processed as controls for real-time reverse-transcription polymerase chain reaction for their RNA expression levels and multiplex assay to determine their protein levels. Statistic analysis was performed using the unpaired t test or Mann-Whitney test according to data distribution and Pearson correlation. IL-6 and CRP were synthesized in ALEOs, whereas their RNA expression and protein levels were significantly higher when compared with healthy periodontal ligament. IL-6 and CRP immunolocalized to the inflammatory cells, vascular endothelial cells, and mesenchymal cells. Both, IL-6 and CRP colocalized in ALEOs, and a positive correlation was found between their expression levels (P periodontal ligament and up-regulated in ALEOs along with higher protein levels. Given their pleiotropic effects, IL-6 and CRP protein levels in apical tissues might partially explain the development and progression of ALEOs as well as potentially asymptomatic apical periodontitis-associated systemic low-grade inflammation.

    Infection is the most common cause of death following burn injury. The study was conducted to compare the diagnostic value of serum procalcitonin (PCT) with the other current benchmarks as early predictors of septic shock and bloodstream infection in burn patients. We included 24 patients admitted to the Burn Unit of a medical center from June 2015 to December 2015 from the Formosa Fun Coast dust explosion. We categorized all patients at initial admission into either sepsis or septic shock groups. Laboratory tests including the worst PCT and C-reactive protein (CRP) levels, platelet (PLT), and white blood cell (WBC) count were performed at <48 h after admission. Patients were also classified in two groups with subsequent bacteremia and non-bacteremia groups during hospitalization. Significantly higher PCT levels were observed among participants with septic shock compared to those with sepsis (47.19 vs. 1.18 ng/mL, respectively; p < 0.001). Patients with bacteremia had significantly elevated PCT levels compared to patients without bacteremia (29.54 versus 1.81 ng/mL, respectively, p < 0.05). No significant differences were found in CRP levels, PLT, and WBC count between the two groups. PCT levels showed reasonable discriminative power (cut-off: 5.12 ng/mL; p = 0.01) in predicting of bloodstream infection in burn patients and the area under receiver operating curves was 0.92. PCT levels can be helpful in determining the septic shock and bloodstream infection in burn patients but CRP levels, PLT, and WBC count were of little diagnostic value. Copyright © 2017.

    A 69-year-old man started taking the dipeptidyl peptidase-4 inhibitor, vildagliptin. One week later, C-reactive protein and plasma immunoglobulin E levels were markedly elevated, and the vildagliptin was stopped. After the patient's laboratory findings were normalized, we decided to restart vildagliptin with the patient's agreement. The next day, he had a high fever, and C-reactive protein and procalcitonin levels were elevated. Although we failed to find a focus of infection, we started antibiotics therapy. Two days later, the high fever had improved, and the C-reactive protein level had decreased. A drug lymphocyte stimulation test showed a positive result for vildagliptin. We examined various kinds of cytokine and infection markers just before and after the treatment with vildagliptin. Finally, we diagnosed the patient with vildagliptin-induced drug fever, probably based on the increase of various inflammatory cytokine levels and the response to this. Taken together, we should be aware of the possibility of vildagliptin inducing drug fever and/or acute inflammation. © 2018 The Authors.

    High levels of C-reactive protein (CRP) are associated with an increased risk of further ischemic events in patients with symptomatic intracranial atherosclerotic disease (ICAD). It remains unknown to which extent this increased risk might be genetically predetermined. We aimed to investigate the relationship between a common genetic polymorphism of the CRP gene and the risk of recurrent ischemic events in symptomatic ICAD patients. We studied 75 consecutive patients with a first-ever cerebral ischemic event attributable to symptomatic ICAD. Blood samples were drawn 3 months after the qualifying event. Genomic DNA was isolated and the C1444T single nucleotide polymorphism (SNP) of the CRP gene was determined. The blood concentration of CRP was also measured. Patients underwent long-term clinical follow-up to detect the occurrence of further major ischemic events. During a median follow-up time of 23 months, 18 patients (24%) suffered a major ischemic event (10 ischemic strokes, 3 transient ischemic attacks and 5 myocardial infarctions). Raised CRP levels at baseline (p = 0.02) and the presence of the T allele within the CRP C1444T SNP were associated with a higher risk of recurrent ischemic events (p = 0.02). Kaplan-Meier and multivariable Cox regression analyses adjusted for age, sex, vascular risk factors and CRP level identified that the presence of the T allele in the studied polymorphism predicted the occurrence of further ischemic events (hazard ratio 3.6, 95% confidence interval 1.2-11.1; p = 0.025). The presence of the T allele within the CRP gene C1444T polymorphism may be associated with a higher risk of further ischemic events in symptomatic ICAD patients. (c) 2009 S. Karger AG, Basel.

    Full Text Available Abstract Background Protein covalent binding by reactive metabolites of drugs, chemicals and natural products can lead to acute cytotoxicity. Recent rapid progress in reactive metabolite target protein identification has shown that adduction is surprisingly selective and inspired the hope that analysis of target proteins might reveal protein factors that differentiate target- vs. non-target proteins and illuminate mechanisms connecting covalent binding to cytotoxicity. Results Sorting 171 known reactive metabolite target proteins revealed a number of GO categories and KEGG pathways to be significantly enriched in targets, but in most cases the classes were too large, and the "percent coverage" too small, to allow meaningful conclusions about mechanisms of toxicity. However, a similar analysis of the directlyinteracting partners of 28 common targets of multiple reactive metabolites revealed highly significant enrichments in terms likely to be highly relevant to cytotoxicity (e.g., MAP kinase pathways, apoptosis, response to unfolded protein. Machine learning was used to rank the contribution of 211 computed protein features to determining protein susceptibility to adduction. Protein lysine (but not cysteine content and protein instability index (i.e., rate of turnover in vivo were among the features most important to determining susceptibility. Conclusion As yet there is no good explanation for why some low-abundance proteins become heavily adducted while some abundant proteins become only lightly adducted in vivo. Analyzing the directly interacting partners of target proteins appears to yield greater insight into mechanisms of toxicity than analyzing target proteins per se. The insights provided can readily be formulated as hypotheses to test in future experimental studies.

    Background: coronary heart disease is multifactorial inflammatory process which involves the accumulation of lipid macrophages and intimal plaques in smooth muscle cell in large and medium sized arteries. C reactive protein (CRP) which is an inflammatory marker is considered as global risk assessment for coronary heart disease. The objective of study is to determine the CRP level as risk marker in coronary heart disease in middle aged individuals. Methods: This cross sectional study was conducted in Hayatabad medical complex Peshawar and Rehman Medical Institute Peshawar. On the basis of predesigned questionnaire, 100 middle aged individuals of age 40-60 years and 50 normal subjects of same age were questioned by taking consent. Data was collected and analysed by SPSS-15. Results: It was founded that 74 percentage of patients have higher values of CRP and 4 percentage have high values of CRP in controls. The t-test applied at 95 percentage confidence interval with mean difference of 22.096+2.36 of CHD individuals and 1.288±1.70 of control group. P-value was 0.001 which is found to be significant. Conclusion: It was observed that CRP has higher association with CHD. (author)

    Inflammation has been implicated in the pathophysiology of a series of cardiovascular diseases. C-reactive protein (CRP) is a marker of inflammation easily obtained in the emergency room. To study the prognostic value of CRP in patients admitted for acute decompensated heart failure (ADHF). A prospective cohort of 119 patients with ADHF treated in the emergency room. Mean age was 74+/-11 years and 76 (64%) of patients were male. All were New York Heart Association Functional Class III or IV. CRP was measured by nephelometry at admission. Patients were followed after hospital discharge for an average of 12+/-9.7 months and cardiovascular mortality was the outcome analyzed. There were 44 (36.9%) deaths, all from cardiovascular causes. Individuals with CRP > 3 mg/dl had higher mortality than those below this level (p=0.018). In the multivariate analysis using Cox proportional model, CRP proved to be the most important independent prognostic factor (odds ratio 0.0916 [95% CI = 0.0341 - 0.1490] for each one-unit increment in CRP). CRP is an independent cardiovascular mortality predictor in patients with ADHF, indicating that inflammation represents an important component in the pathophysiology of the disease.

    Native C-reactive protein (nCRP) is a pentameric oligo-protein and an acute phase reactant whose serum expression is increased in patients with inflammatory disease. We have identified by immunohistochemistry, significant expression of a tissue-binding insoluble modified version or monomeric form of CRP (mCRP) associated with angiogenic microvessels in peri-infarcted regions of patients studied with acute ischaemic stroke. mCRP, but not nCRP was expressed in the cytoplasm and nucleus of damaged neurons. mCRP co-localized with CD105, a marker of angiogenesis in regions of revascularisation. In vitro investigations demonstrated that mCRP was preferentially expressed in human brain microvessel endothelial cells following oxygen-glucose deprivation and mCRP (but not column purified nCRP) associated with the endothelial cell surface, and was angiogenic to vascular endothelial cells, stimulating migration and tube formation in matrigel more strongly than fibroblast growth factor-2. The mechanism of signal transduction was not through the CD16 receptor. Western blotting showed that mCRP stimulated phosphorylation of the key down-stream mitogenic signalling protein ERK1/2. Pharmacological inhibition of ERK1/2 phosphorylation blocked the angiogenic effects of mCRP. We propose that mCRP may contribute to the neovascularization process and because of its abundant presence, be important in modulating angiogenesis in both acute stroke and later during neuro-recovery.

    For label-free and direct detection of C-reactive protein (CRP), an impedimetric sensor based on an indium tin oxide (ITO) electrode array functionalized with reduced graphene oxide-nanoparticle (rGO-NP) hybrid was fabricated and evaluated. Analytical measurements were performed to examine the properties of rGO-NP-modified ITO microelectrodes and to determine the influence upon sensory performance of using nanostructures modified for antibody immobilization and for recognition of CRP binding events. Impedimetric measurements in the presence of the redox couple [Fe(CN)6](3-/4-) showed significant changes in charge transfer resistance upon binding of CRP. The impedance measurements were highly target specific, linear with logarithmic CRP concentrations in PBS and human serum across a 1 ng mL(-1) and 1000 ng mL(-1) range and associated with a detection limits of 0.06 and 0.08 ng mL(-1) respectively.

    Workers of X-rays departments are occupationally exposed to long-term low levels of ionizing radiation. The aim of the study was to investigate the influence of occupational exposure of low-level X-ray radiation on immunoglobulin and C-reactive protein (CRP) concentrations in radiology workers. In the study group of 41 X-ray department workers and the control group composed of 32 persons, immunoglobulins (IgM, IgG,IgA) and CPR concentrations were analyzed. The study group was subdivided by gender and smoking habit. A significant decrease in IgG level was found in the workers and the female subgroup. The same observation was made when smokers and nonsmokers of both groups were compared. Smoking workers showed lower concentrations of IgA than non-smokers. Occupational exposure to low levels of ionizing radiation is associated with suppressive influence on the immunoglobulin production, especially IgG. In addition, smoking decreases the production of IgA in radiology workers. (author)

    C-reactive protein (CRP) has been shown to be associated with several tumors. However, its association with nasopharyngeal carcinoma (NPC) is not well characterized. We performed a literature review and meta-analysis to assess the prognostic relevance of elevated CRP levels in patients with NPC. A literature search for relevant studies was performed on PubMed (Medline), the Cochrane Library, and Web of Science databases. Hazard ratios (95% confidence intervals) were calculated to assess the association between elevated CRP levels and survival outcomes. Five studies with a combined study population of 5215 patients with NPC were included. Pooled hazard ratios for overall survival and distant metastasis-free survival were 1.84 (95% CI = 1.57-2.17) and 1.81 (95% CI = 1.53-2.14), respectively. Subgroup analyses showed that types of indicators and treatment before inclusion had no significant impact on the observed association. Elevated serum CRP levels in patients with NPC were associated with worse prognosis.

    Full Text Available C-reactive protein (CRP is the prototypical acute phase reactant, increasing in blood concentration rapidly and several-fold in response to inflammation. Recent evidence indicates that CRP has an important physiological role even at low, baseline levels, or in the absence of overt inflammation. For example, we have shown that human CRP inhibits the progression of experimental autoimmune encephalomyelitis (EAE in CRP transgenic mice by shifting CD4+ T cells away from the TH1 and toward the TH2 subset. Notably, this action required the inhibitory Fcγ receptor IIB (FcγRIIB, but did not require high levels of human CRP. Herein, we sought to determine if CRP’s influence in EAE might be explained by CRP acting on dendritic cells (DC; antigen presenting cells known to express FcγRIIB. We found that CRP (50 µg/ml reduced the yield of CD11c+ bone marrow-derived DCs (BMDCs and CRP (≥5 μg/ml prevented their full expression of major histocompatibility complex class II and the co-stimulatory molecules CD86 and CD40. CRP also decreased the ability of BMDCs to stimulate antigen-driven proliferation of T cells in vitro. Importantly, if the BMDCs were genetically deficient in mouse FcγRIIB then (i the ability of CRP to alter BMDC surface phenotype and impair T cell proliferation was ablated and (ii CD11c-driven expression of a human FCGR2B transgene rescued the CRP effect. Lastly, the protective influence of CRP in EAE was fully restored in mice with CD11c-driven human FcγRIIB expression. These findings add to the growing evidence that CRP has important biological effects even in the absence of an acute phase response, i.e., CRP acts as a tonic suppressor of the adaptive immune system. The ability of CRP to suppress development, maturation, and function of DCs implicates CRP in the maintenance of peripheral T cell tolerance.

    Recent studies have shown that C-reactive protein (CRP) is a useful predictive factor in several cancers; however, its role in esophageal cancer (EC) is controversial. A systematic literature search was performed using Medline, PubMed, and Web of Science to analyze the prognostic value of serum CRP in patients with EC. A meta-analysis was performed to assess the association between serum CRP and overall survival (OS) in patients with EC. A total of eight studies involving 1,471 patients were included in our study. Our pooled results demonstrated that a high level of serum CRP was associated with poor OS (hazard ratio [HR]: 1.40, 95% confidence interval [CI]: 1.25-1.57, I (2)=81.3%, P<0.0001). Subgroup analyses were performed in further investigations. When the patients were segregated according to treatment, pathological type, and cut-off level, high levels of serum CRP were found to be significantly correlated with OS. Our meta-analysis revealed that high levels of serum CRP were significantly associated with poor OS in patients with EC.

  10. Investigation of two novel biochemical markers of inflammation, matrix metalloproteinase and cathepsin generated fragments of C-reactive protein, in patients with ankylosing spondylitis

    Ankylosing spondylitis (AS) is a chronic inflammation of the spine and the sacroiliac joints. Current markers of inflammation, such as C-reactive protein (CRP), are reflecting the production of an acute phase reactant rather than tissue specific inflammation, but the use of CRP as a diagnostic...... and prognostic marker for AS has not provided the sought accuracy and specificity. We hypothesized that local enzymatic activity in the disease-affected tissue, which is associated with extensive tissue turnover may, by cleavage, modify the CRP produced in the liver. These cleavage products may provide...

    We examined the association between socioeconomic status (SES) discrimination and C-reactive protein (CRP) in a biracial cohort of middle-aged adults using an intersectionality framework. Participants were 401 African-American and White adults from a population-based cohort in the Southeastern United States. SES discrimination was self-reported with a modified Experiences of Discrimination Scale, and CRP levels were assayed from blood samples. Linear regression analyses were used to examine the associations among SES discrimination, race, education, and CRP after controlling for age, gender, racial and gender discrimination, financial and general stress, body mass index, smoking, sleep quality, and depressive symptoms. Intersectional effects were tested using race×SES discrimination, education×SES discrimination and race×education×SES discrimination interactions. Adjusting for sociodemographics, racial discrimination, gender discrimination, and all relevant two-way interaction terms, we observed a significant race×education×SES discrimination interaction (p=0.019). In adjusted models stratified by race and education, SES discrimination was associated with elevated CRP among higher educated African-Americans (β=0.29, p=0.018), but not lower educated African-Americans (β=-0.13, p=0.32); or lower educated (β=-0.02, p=0.92) or higher educated (β=-0.01, p=0.90) Whites. Findings support the relevance of SES discrimination as an important discriminatory stressor for CRP specifically among higher educated African-Americans. Copyright © 2017 Elsevier Ltd.

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

    Human C-reactive protein (CRP) has been used in the risk assessment of coronary events. Human saliva mirrors the body's health and well-being and is noninvasive, easy to collect, and ideal for third-world countries as well as for large patient screening. This study aimed to screen the saliva CRP qualitatively in patients with diabetes (Type 1 and 2) taking in considerations, the diagnostic criteria of metabolic syndrome. Center for diabetes mellitus, prospective study. A total number of 50 Type 2 diabetes (T2D) patients, 25 Type 1 diabetes (T1D) patients, and 25 healthy subjects were recruited from the center for diabetes mellitus. Each patient was assessed clinically, and the anthropometric measures, glycemic status, and lipid profiles were determined. Stimulated salivary flow rate and saliva CRP were determined. All calculations analysis was made using Excel 2003 program for Windows. The results showed that the salivary flow rate in T1D was less than healthy subjects and T2D and CRP was found positive (6 mg/L) in 36% and 56% of patients with T1D and T2D, respectively. Saliva CRP was found to be related to the anthropometric measurement, blood pressure, and glycemic control. We conclude that saliva CRP may be used as a biomarker for metabolic syndrome and its value is obvious in T2D rather than in T1D.

    Differentiate bacterial infections from flare in SLE patients is difficult to do because clinical symptoms of infection is similar to flare. SLE patients with infection require antibiotic therapy with decreased doses of immunosuppressant while in flare diseases require increased immunosuppressant. Procalcitonin (PCT), a biological marker, increased in serum patients with bacterial infections and expected to be a solution of problem. The aim of this study was to examine the function of PCT serum as marker to differentiate bacterial infection and flare in SLE patients. This cross-sectional study was conducted in Adam Malik Hospital from January-July 2017. We examined 80 patients SLE flare (MEX-SLEDAI>5), screen PCT and culture according to focal infection. Data were statistically analyzed. 80 SLE patients divided into 2 groups: bacterial infection group (31 patients) and non-infection/flare group (49 patients). Median PCT levels of bacterial infection group was 1.66 (0.04-8.45)ng/ml while flare group was 0.12 (0.02-0.81)ng/ml. There was significant difference of serum Procalcitonin level between bacterial infection and flare group in SLE patients (p=0.001). Procalcitonin serum levels can be used as a biomarker to differentiate bacterial infections and flare in SLE patients.

    This study assesses the prevalence of recently identified coronary heart disease (CHD) risk factors in young people of differing socioeconomic status (SES). From November 2001 through March 2002, 100 boys and 108 girls, of age 12.9 +/- 0.3 years, selected from differing SES were assessed for CHD risk factors. Measurements included fibrinogen (Fg), homocyst(e)ine (Hcy), and C-reactive protein (CRP). Fibrinogen was significantly greater among boys from a higher SES compared with those from a low SES (P < or = 0.05). Differences according to sex (P < or = 0.05) were identified for Fg and CRP. The data indicate the prevalence of recently identified CHD risk factors in this cohort of British schoolchildren. For the purpose of this article, the phrase "young people" embraces both children and adolescents. Copyright 2005 Wiley-Liss, Inc

    It is not clear whether habitual dietary intake influences the antioxidant or inflammatory status. The aim of the present study was to assess the impact of antioxidative vitamins C, E, and β-carotene obtained from daily food rations on plasma and salivary Total Antioxidant Capacity (TAC), uric acid and salivary C-reactive protein (CRP). The study involved 80 older subjects (66.9 ± 4.3 years), divided into two groups: group 1 ( n = 43) with lower and group 2 ( n = 37) with higher combined vitamins C, E and β-carotene intake. A 24-h dietary recall was obtained from each individual. TAC was assessed simultaneously with two methods in plasma (Ferric Reducing Ability of Plasma-FRAP, 2.2-diphenyl-1-picryl-hydrazyl-DPPH) and in saliva (FRAS and DPPHS test). Lower vitamin C intake corresponded to higher FRAS. There were no other correlations between vitamins C, E or β-carotene intake and antioxidant indices. Salivary CRP was not related to any antioxidant indices. FRAS was decreased in group 2 ( p < 0.01) but no other group differences for salivary or for plasma antioxidant parameters and salivary CRP were found. Habitual, not extra supplemented dietary intake does not significantly affect plasma or salivary TAC and salivary CRP.

    2010-12-21

    Borylnitrenes (catBN 3a and pinBN 3b; cat = catecholato, pin = pinacolato) are reactive intermediates that show high tendency towards insertion into the C-H bonds of unactivated hydrocarbons. The present article summarizes the matrix isolation investigations that were aimed at identifying, characterizing and investigating the chemical behaviour of 3a by spectroscopic means, and of the experiments in solution and in the gas phase that were performed with 3b. Comparison with the reactivity reported for difluorovinylidene 1a in solid argon indicates that 3a shows by and large similar reactivity, but only after photochemical excitation. The derivative 3b inserts into the C-H bonds of hydrocarbon solvents in high yields and thus allows the formation of primary amines, secondary amines, or amides from "unreactive" hydrocarbons. It can also be used for generation of methylamine or methylamide from methane in the gas phase at room temperature. Remaining challenges in the chemistry of borylnitrenes are briefly summarized.

    Preterm premature rupture of membranes (PPROM) is associated with significant maternal and perinatal morbidity. This study examined maternal oxidative stress in PPROM. This was a prospective cross-sectional study conducted in a university hospital. A total of 72 pregnant women were recruited into two groups, those with PPROM (38 cases) and those without PPROM (34 controls) matched for gestational age. Plasma interleukin-6, C-reactive protein, vitamins C, E and A, 8-isoprostane, total oxidant status (TOS) and antioxidant status (TAS) were determined for all study participants and the data were compared between the PPROM and control groups. Both case and control groups were comparably matched in age, parity, gestational age and smoking status. There was a significant association between low 8-isoprostane, low vitamin C and high total oxidant status and the occurrence of PPROM (p vitamin C and 8-isoprostane levels were lower and TOS higher in women with PPROM. Further research is needed to identify robust biological markers for the prevention and also prognosis of PPROM.

    Full Text Available OBJECTIVES: To determine the effect of Helicobacter pylori (H. pylori eradication on blood levels of high-sensitivity C-reactive protein (hs-CRP, macrophage migration inhibitory factor and fetuin-A in patients with dyspepsia who are concurrently infected with H. pylori. METHODS: H.pylori infection was diagnosed based on the 14C urea breath test (UBT and histology. Lansoprazole 30 mg twice daily, amoxicillin 1 g twice daily, and clarithromycin 500 mg twice daily were given to all infected patients for 14 days; 14C UBT was then re-measured. In 30 subjects, migration inhibitory factor, fetuin-A and hs-CRP levels were examined before and after the eradication of H. pylori infection and compared to levels in 30 healthy subjects who tested negative for H. pylori infection. RESULTS: Age and sex distribution were comparable between patients and controls. Migration inhibitory factor and hs-CRP levels were higher, and fetuin-A levels were lower, in H. pylori-infected patients (p0.05. CONCLUSION: These findings suggest that H. pylori eradication reduces the levels of pro-inflammatory cytokines such as migration inhibitory factor and hs-CRP and also results in a significant increase in anti-inflammatory markers such as fetuin-A.

    We sought to determine whether exclusion of infection and antibiotic stewardship with the infection biomarker procalcitonin improves outcomes in congestive heart failure (CHF) patients presenting to emergency departments with respiratory symptoms and suspicion of respiratory infection. We performed a secondary analysis of patients with a past medical history of CHF formerly included in a Swiss multicenter randomized-controlled trial. The trial compared antibiotic stewardship according to a procalcitonin algorithm or state-of-the-art guidelines (controls). The primary endpoint was a 30-day adverse outcome (death, intensive care unit admission); the secondary endpoints included a 30-day antibiotic exposure. In the 110/233 analyzed patients (47.2%) with low initial procalcitonin (<0.25 μg/L), suggesting the absence of systemic bacterial infection, those randomized to procalcitonin guidance (n=50) had a significantly lower adverse outcome rate compared to controls (n=60): 4% vs. 20% (absolute difference -16.0%, 95% confidence interval (CI) -28.4% to -3.6%, P=0.01), and significantly reduced antibiotic exposure [days] (mean 3.7 ± 4.0 vs. 6.5 ± 4.4, difference -2.8 [95% CI, -4.4 to -1.2], P<0.01). When initial procalcitonin was ≥0.25 μg/L, procalcitonin-guided patients had significantly reduced antibiotic exposure due to early stop of therapy without any difference in adverse outcomes (25.8% vs. 24.6%, difference [95% CI] 1.2% [-14.5% to 16.9%, P=0.88]). CHF patients presenting to the emergency department with respiratory symptoms and suspicion for respiratory infection had decreased antibiotic exposure and improved outcomes when procalcitonin measurement was used to exclude bacterial infection and guide antibiotic treatment. These data provide further evidence for the potential harmful effects of antibiotic / fluid treatment when used instead of diuretics and heart failure medication in clinically symptomatic CHF patients without underlying infection.

    Nova Scotia Duck Tolling Retrievers (NSDTRs) are a dog breed often affected by immune-mediated rheumatic disease (IMRD), a disorder characterised by chronic stiffness and joint pain. Most, but not all, dogs with IMRD, have antinuclear antibodies (ANA), which are also commonly present in the autoimmune disease systemic lupus erythematosus (SLE). The clinical and diagnostic findings of IMRD indicate that it is an SLE-related disorder. C-reactive protein (CRP), an acute phase protein, is a quantitative marker of inflammation for many diseases and is used for diagnosing and monitoring systemic inflammation in both humans and dogs. However, in human SLE, CRP concentrations are often elevated but correlate poorly with disease activity; they can be low in individual patients with active disease. The aim of the study was to investigate CRP in a group of NSDTRs with the SLE-related disorder IMRD. The hypothesis was that CRP concentrations would be increased in dogs with IMRD compared to healthy dogs, but that the increase would be mild. Serum CRP concentrations were measured in 18 IMRD-affected NSDTRs and 19 healthy control NSDTRs using two different canine-specific CRP assays. Dogs with IMRD and ANA had higher CRP concentrations than the control dogs, but the concentrations were below the clinical decision limit for systemic inflammation for most of the IMRD dogs. These results indicate that CRP concentrations were increased in dogs with IMRD and ANA, but the increase was mild, similar to what has been observed in human SLE.

Pre-treatment CRP levels were analyzed to determine potential associations with clinicopathological parameters and to assess prognostic value in 46 patients with sole adenocarcinoma of the uterine cervix. The mean (±SD) pre-treatment serum CRP level was 5.82 (7.21) mg/l. Serum CRP concentration significantly correlated positively with age at diagnosis (p=0.001), lymphovascular space invasion (p=0.0026), recurrent disease (p=0.0001) and International Federation of Gynecology and Obstetrics (FIGO) stage (p=0.0002). In multivariate Cox regression models with age, FIGO stage, histological grade and lymph node status, elevated CRP and cancer antigen 125 levels were associated with shortened survival (pcervix.

    The aim of this study was to explore the association between some SNPs of the TNF, LTA, IL1B and IL10 genes with cytokine concentrations and clinical course in Colombian septic patients. We conducted a cross-sectional study to genotype 415 septic patients and 205 patients without sepsis for the SNPs -308(G/A) rs1800629 of TNF; +252 (G/A) rs909253 of LTA; -511(A/G) rs16944 and +3953(C/T) rs1143634 of IL1B; and -1082(A/G) rs1800896, -819(C/T) rs1800871 and -592(C/A) rs1800872 of IL10. The association of theses SNPs with the following parameters was evaluated: (1) the presence of sepsis; (2) severity and clinical outcomes; (3) APACHE II and SOFA scores; and (4) procalcitonin, C-reactive protein, tumor necrosis factor, lymphotoxin alpha, interleukin 1 beta and interleukin 10 plasma concentrations. We found an association between the SNP LTA +252 with the development of sepsis [OR 1.29 (1.00-1.68)]; the SNP IL10 -1082 with sepsis severity [OR 0.53 (0.29-0.97)]; the TNF -308 with mortality [OR 0.33 (0.12-0.95)]; and the IL10 -592 and IL10 -1082 with admission to the intensive care unit (ICU) [OR 3.36 (1.57-7.18)] and [OR 0.18 (0.04-0.86)], respectively. None of the SNPs were associated with cytokine levels, procalcitonin and C-reactive protein serum concentrations, nor with APACHE II and SOFA scores. Our results suggest that these genetic variants play an important role in the development of sepsis and its clinical course.

The role of inflammation in cardiovascular disease has been well documented in the last decade, and inflammation has been demonstrated in all stages of atherosclerosis, from its beginning and growth to the plaque rupture. CRP is an acute phase protein, highly sensitive as a marker of general inflammation. The presence of CRP has been determined in experimental studies in arteries with atherosclerotic lesions. It has been demonstrated as well that CRP induces directly the production of other inflammatory cells and decreases the expression of nitric oxide synthase. This means that from the biological standpoint CRP takes part in the atherogenic process. In adults, CRP detected through high sensitive CRP

    Our objective was to evaluate the effects of small-volume, home-based exercise combined with slight caloric restriction on the inflammatory markers C-reactive protein and adiponectin. In total, 54 women were randomly assigned to one of two groups for exercise intervention: the control or home-based exercise groups. Weight, waist and hip circumferences, and inflammatory markers were measured at baseline and after 6 and 12 months. Women allocated to the home-based exercise group received a booklet explaining the physical exercises to be practiced at home at least 3 times per week, 40 minutes per session, at low-to-moderate intensity. All participants received dietary counseling aimed at reducing caloric intake by 100-300 calories per day, with a normal distribution of macro-nutrients (26-28% of energy as fat). Clinicaltrials.gov: NCT01206413 RESULTS: The home-based exercise group showed a significantly greater reduction in weight and body mass index at six months, but no difference between groups was observed thereafter. With regard to the inflammatory markers, a greater but non-statistically significant reduction was found for C-reactive protein in the home-based exercise group at six months; however, this difference disappeared after adjusting for weight change. No differences in adiponectin were found at the 6- or 12-month follow-up. Small-volume, home-based exercise did not promote changes in inflammatory markers independent of weight change.

    A common single nucleotide polymorphism (SNP) in the gene of brain-derived neurotrophic factor (BDNF) results from a substitution at position 66 from valine (Val) to methionine (Met) and may predispose to human neuropsychiatric disorders. We proposed to determine whether these BDNF gene SNPs were associated with fibromyalgia syndrome (FMS) and/or any of its typical phenotypes. Patients with FMS (N = 95) and healthy normal controls (HNC, N = 58) were studied. Serum high-sensitivity C-reactive protein (hsCRP) levels were measured using an enzyme-linked immunosorbent assay (ELISA). The BDNF SNPs were determined using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP).The BDNF SNP distribution was 65 (68%) Val/Val, 28 (30%) Val/Met, and 2 (2%) Met/Met for FMS and 40 (69%), 17(29%), and 1 (2%) for HNC, respectively. The serum high-sensitivity C-reactive protein (hsCRP)and body mass index (BMI) in FMS were higher than in HNC. The FMS with BDNF Val66Val had significantly higher mean BMI (P = 0.0001) and hsCRP (P = 0.02) than did FMS carrying the Val66Met genotype. This pattern was not found in HNC. Phenotypic measures of subjective pain, pain threshold, depression, or insomnia did not relate to either of the BDNF SNPs in FMS. The relative distribution BDNF SNPs did not differ between FMS and HNC. The BDNF Val66Met polymorphism is not selective for FMS. The BDNF Val66Val SNP identifies a subgroup of FMS with elevated hsCRP and higher BMI. This is the first study to associate a BDNF polymorphism with a FMS subgroup phenotype.

    Weis, Nina; Almdal, Thomas

    2006-01-01

    BACKGROUND: Far from all patients with exacerbation of chronic obstructive pulmonary disease (COPD) benefit from antibiotic treatment. However, as these patients are often colonized with bacteria, even in a stable phase, there is no reliable method for establishing whether the patients have...... a significant bacterial infection and would benefit from antibiotic treatment. C-reactive protein (CRP) has proven to be useful as a marker of bacterial infection. The aim of this study was to assess to what degree CRP is elevated in patients with exacerbation of COPD. METHODS: A total of 166 consecutive...... infection. Thus, it may be used when deciding whether or not to start antibiotic treatment. This should be tested in a controlled trial....

    Aim: The aim of this study is to assess the sensitivity and specificity of procalcitonin to determine bacterial etiology of diarrhea. The examinees and methods: For this purpose we conducted the study comprising 115 children aged 1 to 60 months admitted at the Department of Pediatric Gastroenterology, Pediatric Clinic, divided in three groups based on etiology of the diarrhea that has been confirmed with respective tests during the hospitalization. Each group has equal number of patients – 35. The first group was confirmed to have bacterial diarrhea, the second viral diarrhea and the third extra intestinal diarrhea. The determination of procalcitonin has been established with the ELFA methods of producer B.R.A.H.M.S Diagnostica GmbH, Berlin, (Germany). Results: From the total number of 1130 patient with acute diarrhea procalcitonin was assessed in 105. 67 (63.8%) of these patient were male. More than one third (38.14%) of the children in our study were younger then 12 months. Approximately the same was the number of children 13-24 months (33 patients or 31.43%) and 25-60 months (32 patients or 30.43%). The mean value of PRC in children with viral diarrhea was 0.13±0.5 ng/mL in children with bacterial diarrhea was 5.3±4.9 ng/m Land in children with extra intestinal diarrhea was 1.7±2.8 ng/mL. When measured using ANOVA and Turkey HSD tests, results have shown the statistical significance when comparing viral with bacterial and extra intestinal diarrhea but were statistically insignificant when comparing bacterial and extra intestinal diarrhea. Conclusion: Procalcitonin is an important but not conclusive marker of bacterial etiology of acute diarrhea in children younger than 5 years. PMID:24944526

    Background: The diagnosis of bacterial infection in cirrhotic patients may be difficult, because of the absence of classical signs such as fever and raised white blood cell count. The role of C-reactive protein (CRP) in this context has not been clearly defined. Methods: Clinical and laboratory characteristics of 210 consecutive cirrhotic patients with (n=100) or without (n=110) bacterial infection were compared with a control group of non-cirrhotic patients with infection (n=106). Results: Significantly fewer patients with cirrhosis had a body temperature ≥37°C when presenting with bacterial infection (56% cirrhotic vs. 85.5% non-cirrhotic patients, P=0.01). Mean leukocyte count was 6.92 × 103/mm3 in patients with cirrhosis and infection, 5.75 × 103/mm3 (P=0.02) in cirrhotic patients without infection, and 11.28 × 103/mm3 in non-cirrhotic patients with infection (P10 mg/L indicated the presence of infection with a sensitivity of 68%, a specificity of 84.5% and an area under the receiver operating characteristic curve of 0.8197. CRP cutoff level differed according to the severity of the liver disease: Child-Pugh score (CPS) A: 21.3 mg/L, B: 17 mg/L, and C: 5.78 mg/L. Conclusions: CRP at admission could help diagnose infection in cirrhotic patients. Since the severity of liver disease seems to affect the CRP values, lower CRP levels might indicate infection. Clinical suspicion is necessary to avoid delay in diagnosis and initiate antibiotic treatment. PMID:29333070

  14. C-reactive protein in the hemolymph of Achatina fulica: interrelationship with sex steroids and metallothionein.

    Bose, R; Bhattacharya, S

    2000-04-01

    C-reactive protein in Achatina fulica (ACRP) is a normal component of the hemolymph. Its concentration varied from 1mg/ml in the newly hatched male, 3-5 mg/ml in the most active hermaphrodite and 1.5-2.8 mg/ml in the sedentary female showing a direct relationship of the protein with the active phase of the animal. ACRP has a molecular mass of 400 kDa and showed high absorbance in the region of 200-230 nm. It has four subunits with relative molecular masses of 110, 90, 62 and 60 kDa, respectively. Interestingly, rat platelet aggregation in vitro was significantly enhanced by ACRP in presence of 10 microM ADP and 2 mM Ca(2+) suggesting a probable role of ACRP in the aggregation of amoebocytes during the formation of plug in injured tissue. Like other vertebrate CRPs, ACRP also acts as a scavenger of chromatin fragments as evidenced by its binding to poly-L-arginine. Among the sex steroids, 4-androstenedione induces ACRP synthesis in the newly hatched male reaching the level found in the most active hermaphrodite phase (4 mg/ml). A very high molar ratio (5) of mercury binding to ACRP confirmed its sequestration property of heavy metals as observed in vertebrates. The level of metallothionein (MT) in the hemolymph gradually increased from the male to the hermaphrodite to the female, a pattern distinctly different from that of the ACRP titer. Since both MT and ACRP can sequester inorganic mercury, the high level of MT compensates functionally for the low titer of ACRP in the sedentary female.

    To investigate the early upper gastrointestinal endoscopy (endoscopy) significantly reduces mortality resulting from upper gastrointestinal (GI) bleeding. Upper GI bleeding was defined as 1a, 1b, 2a, and 2b according to the Forrest classification. The hemoglobin (Hb), and C-reactive protein (CRP) were examined at around the day of endoscopy and 3 mo prior to endoscopy. The rate of change was calculated as follows: (the result of blood examination on the day of endoscopy - the results of blood examination 3 mo prior to endoscopy)/(results of blood examination 3 mo prior to endoscopy). Receiver operating characteristic curves were created to determine threshold values. Seventy-nine men and 77 women were enrolled. There were 17 patients with upper GI bleeding: 12 with a gastric ulcer, 3 with a duodenal ulcer, 1 with an acute gastric mucosal lesion, and 1 with gastric cancer. The area under the curve (AUC), threshold, sensitivity, and specificity of Hb around the day of endoscopy were 0.902, 11.7 g/dL, 94.1%, and 77.1%, respectively, while those of CRP were 0.722, 0.5 mg/dL, 70.5%, and 73%, respectively. The AUC, threshold, sensitivity, and specificity of the rate of change of Hb were 0.851, -21.3%, 76.4%, and 82.6%, respectively, while those of CRP were 0.901, 100%, 100%, and 82.5%, respectively. Predictors for upper GI bleeding were Hb 21.3% and an increase in the CRP > 100%, 3 mo before endoscopy.

    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. 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. 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. 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. © 2013 S.

    This study aimed to compare the effect of single-visit full-mouth mechanical debridement (FMD) and quadrant-wise mechanical debridement (QMD) on the levels of serum interleukin (IL)-6, C-reactive protein (CRP) and soluble thrombomodulin. Thirty-six subjects with chronic periodontitis were randomly allocated to three groups: undergoing QMD, single-visit FMD with povidone iodine or with water. Serum IL-6 and soluble thrombomodulin were measured by enzyme-linked immunosorbent assay, and serum CRP was measured by the latex-enhanced nephelometric method. Serum IL-6 level increased significantly immediately after debridement in all the three groups, with this increase being greatest in the full-mouth groups. However, the increase in the full-mouth groups was not significantly higher than that of quadrant-wise group. In the quadrant-wise group, serum IL-6 level decreased significantly 1 month after debridement compared with baseline. Serum-soluble thrombomodulin decreased significantly in the full-mouth groups but not in the quadrant-wise group. Changes in CRP level were not significant at baseline or after debridement in all the three groups. FMD increased serum IL-6 and reduced serum-soluble thrombomodulin to a greater extent than QMD, suggesting that the former technique has stronger transient effects on systemic vascular endothelial functions than the latter.

    Metabolic syndrome (MetS) has been found to be associated with inflammatory molecules. This study was conducted among 125 MetS patients at B P Koirala Institute of Health Sciences, Dharan, Nepal to find an association of high-sensitivity C-reactive protein (hs-CRP) and serum uric acid with MetS components. Anthropometric measurements, blood pressure, medical history and blood samples were taken. Estimation of hs-CRP, serum uric acid, blood glucose, triglyceride and high density lipoprotein (HDL) cholesterol was done. hs-CRP had positive correlation with blood glucose (r = 0.2, p = 0.026) and negative with HDL cholesterol (r = -0.361, p high uric acid were individually associated with higher odds for low HDL cholesterol (7.992; 1.785-35.774, p = 0.002) and hyperglycemia (2.471; 1.111-5.495, p = 0.029) respectively. Combined rise of hs-CRP and uric acid was associated with severity of MetS (p rise of hs-CRP or uric acid. The present study demonstrates that hs-CRP and serum uric acid are associated with MetS components, and the combined rise of hs-CRP and uric acid is associated with the increase in severity of MetS.

    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.

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

    Increased levels of inflammatory markers, namely, high-sensitive C-reactive protein (hs-CRP), have been associated with several chronic diseases including atherosclerosis, type 2 diabetes and hypertension. Forty-five women and men aged >64 years participated in the study and were randomly assigned to two exercise intervention groups and a non-exercising control group. The participants assigned to the exercising groups followed a 16-week exercise protocol based either on aerobic training (AT) or strength training (ST) followed by a further 16 weeks off-training period. The control group (C) remained sedentary throughout the study. Evaluation of body mass, BMI, waist circumference, aerobic endurance, lower-body strength, upper-body strength, triglycerides, total cholesterol, LDL-cholesterol, HDL-cholesterol and hs-CRP were performed at baseline, after 16 weeks (post-training for the exercise groups) and at 32 weeks (follow-up). Both, AT and ST groups significantly increased functional fitness at the end of the exercise programs when compared to baseline values. hs-CRP concentrations were maintained throughout the study for the C group, while decreasing 10% at 16 weeks and 51% at 32 weeks for the AT group. In the ST group the hs-CRP concentrations decreased by 11 and 39% at 16 and 32 weeks, respectively. Decreases in hs-CRP concentrations were statistically significant for the AT and ST groups at the 32-week evaluation when compared to baseline. Reduction in hs-CRP concentrations seemed to be associated with strength gains and adiposity loss.

    We report a case of marked elevation of the procalcitonin level in umbilical blood and neonatal blood at birth. The mother did not perceive fetal motion. Antepartum fetal heart rate monitoring showed a loss of variability and absence of acceleration. No fetal breathing movement, fetal movement, or fetal tone were observed by ultrasonography. The female neonate was delivered by cesarean section at 25 weeks of gestation, with birthweight 774 g. The umbilical arterial pH value at birth was 7.29. Mild elevation in interleukin-6 and tumor necrosis factor-α in umbilical blood were observed. Cytochrome c showed a high level in umbilical and neonatal blood at birth. Placental histopathology revealed multiple fetal vessel thrombosis in the large stem villi and chorionic vessels. The neonate showed no infectious signs throughout the neonatal period. Computed tomography at 3 months of age revealed atrophy in the cerebrum and cerebellum. At 1 year after birth, the infant showed spastic quadriplegia. In this case, antepartum asphyxia due to fetal vessel thrombosis may have influenced the elevation of procalcitonin level in umbilical blood and neonatal blood at birth. © 2015 Japan Society of Obstetrics and Gynecology.

    Objective: To investigate the changes of serum high sensitive C-reactive protein (hs-CRP) in different stages of diabetic nephropathy and their clinical significance. Methods: Serum hs-CRP was measured by enzyme-linked immunosorbent assay (ELISA), U-Alb was measured by radioimmunoassay(RIA). According to their urinary albumin excretion rate(UAER), 102 patients with type 2 diabetes mellitus were divided into three groups: 40 patients with normal UAER, 32 patients with microalbuminuria and 30 patients with clinical proteinuria, and 32 healthy subjects were taken as the controls control. Results: hs-CRP concentrations were significantly higher in patients with type 2 diabetes mellitus than those in healthy controls and increased with increment of UAER and serum creatinine. Conclusions: The level of hs-CRP is correlated with the extend of diabetic nephropathy in patients with type 2 diabetic patients.The concentration of hs-CRP can in some degree serve as a predictor for diabetic rephropathy and its progression.

    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.

    Full Text Available Ras proteins are crucial players in differentiation and oncogenesis and constitute important drug targets. The localization and activity of Ras proteins are highly dependent on posttranslational modifications at their C-termini. In addition to an isoprenylated cysteine, H-Ras, but not other Ras proteins, possesses two cysteine residues (C181 and C184 in the C-terminal hypervariable domain that act as palmitoylation sites in cells. Cyclopentenone prostaglandins (cyPG are reactive lipidic mediators that covalently bind to H-Ras and activate H-Ras dependent pathways. Dienone cyPG, such as 15-deoxy-Δ(12,14-PGJ(2 (15d-PGJ(2 and Δ(12-PGJ(2 selectively bind to the H-Ras hypervariable domain. Here we show that these cyPG bind simultaneously C181 and C184 of H-Ras, thus potentially altering the conformational tendencies of the hypervariable domain. Based on these results, we have explored the capacity of several bifunctional cysteine reactive small molecules to bind to the hypervariable domain of H-Ras proteins. Interestingly, phenylarsine oxide (PAO, a widely used tyrosine phosphatase inhibitor, and dibromobimane, a cross-linking agent used for cysteine mapping, effectively bind H-Ras hypervariable domain. The interaction of PAO with H-Ras takes place in vitro and in cells and blocks modification of H-Ras by 15d-PGJ(2. Moreover, PAO treatment selectively alters H-Ras membrane partition and the pattern of H-Ras activation in cells, from the plasma membrane to endomembranes. These results identify H-Ras as a novel target for PAO. More importantly, these observations reveal that small molecules or reactive intermediates interacting with spatially vicinal cysteines induce intramolecular cross-linking of H-Ras C-terminus potentially contributing to the modulation of Ras-dependent pathways.

    The clinical significance of the systemic inflammatory response (SIR) in patients with rectal cancer undergoing neoadjuvant chemoradiotherapy (CRT), to the best of our knowledge, has not been thus far investigated. The neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR) and C-Reactive protein (CRP) levels for 84 patients with rectal cancer undergoing CRT were available as indicators of SIR status. The impact of SIR status on the prognosis of these patients was assessed. Elevated NLR, CRP, carcinoembryonic antigen (CEA) and pathological TNM stage III [ypN(+)] were identified as significant prognostic factors for poor overall survival (OS), with CRP and ypN(+) being validated as independent predictors of OS. Elevated CRP and CEA levels were significant predictive factors for poor disease-free survival (DFS), and an elevated CRP level was identified as the only independent predictive factor for DFS. In addition, an elevated CRP level predicted for poorer OS and DFS in patients with pathological TNM stage I-II [ypN(-)]. CRP is a promising predictor of recurrence and prognosis in patients with rectal cancer treated by CRT.

    The developmental origins of adult disease hypothesis suggests that the intrauterine environment may program postnatal health outcomes through mechanisms such as chronic inflammation. The purpose of this article was to review the literature on the association between infant birth weight and C-reactive protein (CRP), markers of the fetal environment and inflammation, respectively. We used PubMed, Google Scholar, Web of Science, ScienceDirect, the citation lists of the reviewed literature, and recommendations from experts in the field to identify potential articles. Inclusion criteria for the studies, regardless of study design, included human subjects, documented or self-reported infant birth weight, and a minimum of one measurement of CRP (during childhood, adolescence, or adulthood). Several studies demonstrated a statistically significant inverse association between birth weight and CRP in adulthood, although in many cases only after controlling for markers of current adiposity. No studies significantly linked birth weight to CRP in childhood or adolescence. Longitudinal studies, including multigenerational studies, are needed to further understand whether adult CRP has origins in the fetal environment. Copyright © 2015 Elsevier Inc.

    It has previously been reported that increased level of serum heat shock proteins (Hsps) antibody in patients with metabolic syndrome. It is possible that the expression of Hsp and inflammatory markers can be affected by cupping and traditional Chinese medicine. There is a little data investigating the effects of cupping on markers of inflammation and Hsp proteins, hence, the objective of this study was evaluation of the effects of wet cupping on serum high-sensitivity C-reactive protein (hs-CRP) and Hsp27 antibody titers in patients with metabolic syndrome. Serum Hs-CRP and Hsp27 antibody titers were assessed in samples from 126 patients with metabolic syndrome (18-65 years of age) at baseline, and after 6 and 12 weeks after treatment. One hundred and twenty-six patients were randomly divided into the experimental group treated with wet cupping combined with dietary advice, and the control group treated with dietary advice alone using a random number table. Eight patients in case group and five subjects in control groups were excluded from the study. Data were analyzed using SPSS 15.0 software and a repeated measure ANCOVA. Serum hs-CRP titers did not change significantly between groups (p>0.05) and times (p=0.27). The same result was found for Hsp27 titers (p>0.05). Wet-cupping on the interscapular region has no effect on serum hs-CRP and Hsp27 patients with metabolic syndrome. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Full Text Available Objective: The primary outcome was to determine whether serum procalcitonin-guided antibiotic therapy can reduce antibiotic exposure in patients with an acute exacerbation of asthma presenting to the primary care facility or emergency department, or during hospital admission. The secondary outcome was the need for mechanical ventilation. Methods: An extensive literature search was performed to identify randomized controlled clinical trials (published in English that compared serum procalcitonin-guided antibiotic therapy versus antibiotic use according to physician’s discretion for adult participants with mild, moderate, or severe acute asthma exacerbations. Results: Four randomized controlled trials evaluating 457 patients were included in this meta-analysis, with significant homogeneity observed among these studies. Procalcitonin-based protocols decreased antibiotic prescriptions (relative risk 0.58, 95% confidence interval 0.50–0.67. The conclusion regarding the difference between the two groups in the need for mechanical ventilation (relative risk 1.10, 95% confidence interval 0.62–1.94 was guarded due to inadequate power and the potential for type II error. The overall quality of evidence was also limited by the lack of double-blinding. Conclusions: These data suggest a potential benefit for the use of serum procalcitonin in guiding antibiotic therapy in patients with an acute asthma exacerbation and advocates the need for more randomized controlled trials.

    Full Text Available Many hypothyroid and autoimmune thyroid patients experience reactions with specific foods. Additionally, food interactions may play a role in a subset of individuals who have difficulty finding a suitable thyroid hormone dosage. Our study was designed to investigate the potential role of dietary protein immune reactivity with thyroid hormones and thyroid axis target sites. We identified immune reactivity between dietary proteins and target sites on the thyroid axis that includes thyroid hormones, thyroid receptors, enzymes, and transport proteins. We also measured immune reactivity of either target specific monoclonal or polyclonal antibodies for thyroid-stimulating hormone (TSH receptor, 5′deiodinase, thyroid peroxidase, thyroglobulin, thyroxine-binding globulin, thyroxine, and triiodothyronine against 204 purified dietary proteins commonly consumed in cooked and raw forms. Dietary protein determinants included unmodified (raw and modified (cooked and roasted foods, herbs, spices, food gums, brewed beverages, and additives. There were no dietary protein immune reactions with TSH receptor, thyroid peroxidase, and thyroxine-binding globulin. However, specific antigen-antibody immune reactivity was identified with several purified food proteins with triiodothyronine, thyroxine, thyroglobulin, and 5′deiodinase. Laboratory analysis of immunological cross-reactivity between thyroid target sites and dietary proteins is the initial step necessary in determining whether dietary proteins may play a potential immunoreactive role in autoimmune thyroid disease.

    Full Text Available BACKGROUND: C-reactive protein (CRP and erythrocyte sedimentation rate (ESR have been shown to be useful for diagnosis of prosthetic hip and knee infection. Little information is available on CRP and ESR in patients undergoing revision or resection of shoulder arthroplasties or spine implants. METHODS/RESULTS: We analyzed preoperative CRP and ESR in 636 subjects who underwent knee (n=297, hip (n=221 or shoulder (n=64 arthroplasty, or spine implant (n=54 removal. A standardized definition of orthopedic implant-associated infection was applied. Receiver operating curve analysis was used to determine ideal cutoff values for differentiating infected from non-infected cases. ESR was significantly different in subjects with aseptic failure infection of knee (median 11 and 53.5 mm/h, respectively, p=<0.0001 and hip (median 11 and 30 mm/h, respectively, p=<0.0001 arthroplasties and spine implants (median 10 and 48.5 mm/h, respectively, p=0.0033, but not shoulder arthroplasties (median 10 and 9 mm/h, respectively, p=0.9883. Optimized ESR cutoffs for knee, hip and shoulder arthroplasties and spine implants were 19, 13, 26, and 45 mm/h, respectively. Using these cutoffs, sensitivity and specificity to detect infection were 89 and 74% for knee, 82 and 60% for hip, and 32 and 93% for shoulder arthroplasties, and 57 and 90% for spine implants. CRP was significantly different in subjects with aseptic failure and infection of knee (median 4 and 51 mg/l, respectively, p<0.0001, hip (median 3 and 18 mg/l, respectively, p<0.0001, and shoulder (median 3 and 10 mg/l, respectively, p=0.01 arthroplasties, and spine implants (median 3 and 20 mg/l, respectively, p=0.0011. Optimized CRP cutoffs for knee, hip, and shoulder arthroplasties, and spine implants were 14.5, 10.3, 7, and 4.6 mg/l, respectively. Using these cutoffs, sensitivity and specificity to detect infection were 79 and 88% for knee, 74 and 79% for hip, and 63 and 73% for shoulder arthroplasties, and 79 and

    We investigated the relationship between C-reactive protein (CRP) and homocysteine on follow-up and subsequent mortality in young ischemic stroke patients in a population-based study. Young ischemic stroke patients were followed-up on average 6 years after the index stroke. CRP and homocysteine levels were measured and risk factors were recorded, including myocardial infarction, diabetes mellitus, hypertension, smoking, alcoholism, and cancer. Stroke outcome was measured using the modified Rankin Scale score. Subsequent survival was obtained by examining the official population registry. Cox regression analyses were performed. In total, 198 patients were included in this study (82 [41%] women and 116 [59%] men). The mean age on follow-up was 47.8 years. In total, 36 (18.2%) patients died during the subsequent mean follow-up of 12.4 years. Cox regression analysis revealed that mortality was associated with CRP (hazard ratio [HR] 1.05; P=.001) and homocysteine levels (HR 1.04; P=.02) in patients without dissection. Kaplan-Meier curves grouped by dichotomized CRP (CRP≤1 v >1 mg/L) showed increasing separation between the survival curves, and likewise for dichotomized homocysteine (≤9 v >9 μg/L). There is an independent association between CRP and homocysteine levels obtained several years after ischemic stroke in young adults and subsequent mortality, even when adjusting for traditional risk factors. This association seems to continue for at least 12 years after the measurements. Copyright © 2013 National Stroke Association. Published by Elsevier Inc. All rights reserved.

    Background: circulating measures of inflammatory markers, such as C-reactive protein (CRP) have been associated with an increased risk of future cognitive decline. However, the nature of the relationship among the very old (>75 years) is unclear. Cross-sectional evidence suggests that elevated CRP may even be protective in this age group. This study examines these associations longitudinally. Methods: logistic regression was used to investigate the association between CRP and drop in cognitive performance (≥3 point change on the Mini-Mental State Examination) over a 4-year period in a population of 266 people, mean age 77 years. Results: increased levels of CRP were associated with a decreased risk of a drop in cognitive performance; however, this association was only seen in those without an APOE e4 allele [odds ratio of decline per unit increase in ln(CRP) 0.57, P = 0.04]. The magnitude of the finding remained consistent after adjustment for cardiovascular confounders (smoking, drinking, MI, stroke, diabetes, education, medication and blood pressure). For those with an e4 allele, the relationship with longitudinal cognitive decline was neither statistically significant nor in a consistent direction after controlling for acute inflammation. Conclusions: this study strengthens previous cross-sectional findings and shows elevated levels of CRP to be linked to a decreased risk of longitudinal cognitive decline in the very old. However, as with prior analyses, this was only observed in those not carrying an APOE e4 allele. Future work on larger APOE e4 allele carrying samples is required to determine the nature of the association in this population. PMID:24305621

    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.
