The Relationship

In this article, we studied complete blood count, serum C-reactive protein (CRP) and interleukin (IL-6) levels in 30 newborn infants with sepsis at admission, in the 24th hour of admission and at the end of the treatment. Our purpose was to determine the relationship among these parameters in the early diagnosis of neonatal sepsis. In our study, there was not a significant difference in white blood cell (WBC) and thrombocyte count among the values of the first, 24th hour and end of therapy in the study group (P>0.05). However, there was not a significant difference in B/N ratio among the values at admission, 24th hour and end of therapy in the study group (P>0.05). Both serum CRP and IL-6 levels were found to be significantly higher than those of control subjects at the beginning (P<0.05). Similarly, the values obtained on the 24th hour were also elevated. However, at the end of therapy both decreased to normal level (P<0.05). Based on these data, we think that serum CRP levels only which is a simple method may be used in the diagnosis of neonatal sepsis. However, WBC and serum IL-6 levels may be useful to establish mortality, because there was a statistically significant difference for these parameters between the survivors and deaths (P<0.05).

Abstract Introduction C-reactive protein (CRP) and procalcitonin (PCT) are widely used as markers of inflammation and infection in general population and in chronic hemodialysis (HD) as well. However, in dialysis (D) patients, serum CRP and PCT levels may be elevated even in the absence of inflammatory or infectious disease and diagnostic process is a challenge in such cases. We studied HD patients' laboratory profile concerning CRP and PCT. Subjects and Methods We studied 25 stable HD patients, M/F=22/3, aged 68(44-89) years, dialyzed thrice weekly for 55(6-274) months with a dialysate flow rate of 700 ml/min, with a residual daily diuresis less than 200 ml, Kt/V values of 1,44±0,3 and no signs of infection. Patients were classified in two groups. Group A included 10 patients on pre-dilution online hemodiafiltration (HDF). Group B consisted of 15 patients on conventional HD with low-flux polysulfone membrane. Twenty healthy subjects formed a control group C. Serum CRP and PCT levels were measured in duplicate in A and B groups before and at the end of mid-week dialysis sessions and also in C group. Results Pre-D serum CRP values in the total of patients were higher than those in healthy controls (10,89±19,29 vs 2,54±1,28 mg/L-p=0,004). Compared with group C, pre-D CRP values were higher only in B group (15,98±24,54 mg/L-p=0,001) but not in A group (4,09±3,33 mg/L-p=NS). There was a significant difference in pre-D serum CRP values between A and B groups (p=0,028). At the end of D session serum CRP values showed a tendency to increase in both groups A (5,16±4,81 mg/L) and B (17,00±27,00 mg/L) but differences were not significant. Pre-D serum PCT values in the total of patients were higher than those in healthy controls (0,82±0,9 vs 0,29±0,55 ng/ml-p&lt;0,001). Compared with group C, pre-D PCT values were higher in both A group (0,52±0,15 ng/ml-p&lt;0,001) and B group (1,01±1,13 ng/ml-p=0,006). There was no significant difference in pre-D serum PCT values between A and B groups (p=0,261). At the end of D session serum PCT values decreased in A group (0,32±0,11 ng/ml-p&lt;0,001) and increased in B group (1,12±1,21 ng/ml-p=0,014). Conclusions In patients on both conventional low-flux HD and online HDF pre-D serum CRP and PCT levels were higher than those in healthy subjects. Dialysis modality and membrane flux did not affect post-D serum CRP values, but post-PCT values decreased in online HDF. PCT usefulness might be limited in dialysis with high-flux membranes. Cut-off values have to be established for both markers to eliminate confusion in diagnosis of inflammatory and infectious diseases in hemodialyzed patients.

ObjectiveTo study the relationship between serum C reactive protein (CRP) levels, genetic variation in the CRP gene and the prevalence, incidence and progression of radiographic osteoarthritis (ROA) in the Rotterdam Study-I (RS-I). A systematic review of studies assessing the relationship between osteoarthritis (OA) and CRP levels was also performed.MethodsThe association between CRP levels and genetic variation in the CRP gene and ROA was examined in 861 patients with hand OA, 718 with knee OA, 349 with hip OA and 2806 controls in the RS-I using one-way analysis of covariance and logistic regression, respectively. PubMed was searched for articles published between January 1992 and August 2009 assessing the relationship between CRP levels and OA.ResultsIn RS-I the prevalence of knee OA, but not hip OA or hand OA, was associated with 14% higher serum CRP levels compared with controls (p=0.001). This association disappeared after adjustment for age and especially body mass index (BMI) (p=0.33). Genetic variation of the CRP gene was not consistently associated with the prevalence, incidence or progression of OA within RS-I. The systematic review included 18 studies (including RS-I) on serum CRP levels and the prevalence, incidence or progression of OA. Consistently higher crude CRP levels were found in cases of prevalent knee OA compared with controls. No association was observed between serum CRP levels and the prevalence of knee OA following adjustment for BMI (n=3 studies, meta-analysis p value=0.61).ConclusionThere is no evidence of association between serum CRP levels or genetic variation in the CRP gene with the prevalence, incidence or progression of OA independent of BMI.

Abstract Context.—Early diagnosis of neonatal sepsis is mandatory. Various markers are used to diagnose the condition. Objective.—To evaluate the diagnostic value of various clinical data and hematologic parameters, such as total leukocyte count, absolute neutrophil count, immature to total neutrophil ratio, and soluble E-selectin (sE-selectin) in identification and outcome of neonatal sepsis. Design.—Newborn infants with a clinical diagnosis of sepsis in the neonatal intensive care unit at Mansoura University Children's Hospital during the period between July 2007 and December 2007 were eligible for study. In addition, 30 healthy neonates were included in the study. Complete hematologic and microbiologic laboratory investigations were performed, and serum E-selectin was measured. Results.—Plasma sE-selectin levels were significantly higher (P &lt; .001) in infected infants (mean [SD], 156.9 [77.0] ng/mL) than in noninfected (mean [SD], 88.8 [47.1] ng/mL) and healthy infants (mean [SD], 8.67 [3.74] ng/ mL). Infants with gram-negative sepsis had higher sE-selectin levels than did those with gram-positive sepsis (P = .04). C-reactive protein was the best laboratory test for diagnosis of neonatal sepsis, with an overall sensitivity and specificity of 86% and 97%, respectively. Performing sE-selectin with C-reactive protein or immature to total ratio tests increased the specificity, but reduced the sensitivity, of the tests for the determination of neonatal sepsis. Plasma sE-selectin levels were higher in nonsurvivors than in survivors (P = .01) and were higher in those with hemodynamic dysfunction than in those without hemodynamic dysfunction (P &lt; .001). Conclusions.—We conclude that plasma sE-selectin levels are elevated in neonatal sepsis. Significant elevation was associated with gram-negative sepsis. Plasma sE-selectin had low diagnostic value when used alone or in combination with other tests; however, it can be used as a prognostic indicator for the outcome of neonatal sepsis.

The Impact

Abstract Objectives This study aimed to examine the impact of hyperbaric oxygen therapy (HBOT) on serum C-reactive protein (CRP) levels, osteoclast numbers, and osteoprotegerin (OPG) expression in periodontitis-induced diabetic rats Materials and Methods This study constituted an in vivo laboratory-based experiment incorporating a posttest only control group design. Thirty male Wistar rats were divided into three groups of research subjects: a healthy group (K0), periodontitis-induced diabetic group (K1), and periodontitis-induced diabetic group treated with HBOT for 7 days (K2). After treatment, the subjects were sacrificed to determine the level of serum CRP by the ELISA method. Immunohistochemical analysis was conducted to check the level of OPG expression, while a histological analysis was undertaken to quantify the number of osteoclasts. Statistical Analysis The data was analyzed using a one-way ANOVA and Least Significant Difference (LSD) test on which a result of p < 0.05 was considered statistically significant. Results HBOT appreciably decreased serum CRP levels, significantly enhancing OPG expression in periodontitis-induced diabetic (p < 0.05) and decreasing the number of osteoclasts in -periodontitis-induced diabetic (p > 0.05). Conclusion HBOT reduced the serum CRP level, increased OPG expression, and decreased osteoclast numbers in periodontitis-induced diabetic rats.

e14110 Background: Serum CRP was previously reported in myeloma to activate membrane bound Fcγ receptors which in turn activated Akt, and MAP kinase and inhibited caspase cascade activation resulting in increased tumour cell proliferation and inhibition of apoptosis. This study investigated the hypothesis that serum C-reactive protein (CRP) may activate signalling pathways in colorectal tumour cells. Methods: A cohort of 147 colorectal tumours was established and immunohistochemistry performed to assess protein expression of CRP, MAP kinase and Akt phosphorylated at serine 473 (pAkt). In addition, reverse transcriptase PCR for CRP mRNA expression was performed on 31 malignant colorectal specimens, 20 non-malignant colorectal specimens and 30 liver specimens. Results: No association between patient survival and tumour expression of CRP, pAkt and MAPK was observed, but serum CRP was independently associated with cancer-specific survival (p<0.001). When analysed according to tumour site, cytoplasmic CRP expression was associated with cancer specific survival in left sided tumours (p=0.022) and cytoplasmic pAkt was associated with cancer specific survival (p=0.029) in rectal tumours. No correlations were observed between serum CRP and tumour expression of CRP, pAkt and MAPK in the cohort as a whole or when subdivided by site. Conclusions: No link was established between serum CRP and signalling within the tumour. However, our results do support the concept of colorectal tumour heterogeneity, as different proteins were associated with patient survival depending on site. Further work is therefore required to elucidate the mechanisms underlying colorectal development and progression in tumour subtypes.

Abstract Objective Noninvasive markers have been increasingly used as a diagnostic marker for sepsis detection and monitoring of the disease. The aim of this observational, prospective pilot study was to investigate the diagnostic performance of urinary soluble triggering receptor expressed on myeloid cells (sTREM-1) and urine C-reactive protein (CRP) levels in the late onset neonatal sepsis and to compare them with serum CRP levels. Materials and Methods Sixty-six infants with clinical sepsis were included. Urine sTREM-1 and urine CRP were collected at the diagnosis of late-onset sepsis. All laboratory investigations were also noted from the infants. Results There were no significant differences between characteristics of the infants. Culture-positive neonates had significantly higher urine sTREM-1 than culture-negative neonates (p < 0.001). Using a cut-off point for urine sTREM-1 of 129 pg/mL, the sensitivity was 0.63, the specificity was 0.84, positive predictive value was 0.80, negative predictive value was 0.70. Urine sTREM-1 and urine CRP were recollected on the seventh day of sepsis treatment and it was found that the levels of sTREM-1 and CRP decreased. Conclusion This is the first study in the literature which evaluates the place of urine sTREM-1 and urine CRP in the diagnosis of neonatal sepsis. Urine sTREM-1 and urine CRP may be useful in the diagnosis of sepsis and in evaluating the effect of antibiotic treatment.

Abstract Background: Platelet indices are used to evaluate platelet activation and function which change in inflammatory diseases. We hypothesise that platelet indices such as plateletcrit, mean platelet volume, and platelet distribution width may be more useful as prognostic indicators for myopericarditis in children. Methods: A total of 60 children were included in this study. Group 1 consists of children with myopericarditis, Group 2 is those with respiratory infections, and Group 3 consists of control group children of similar age and gender with the patient groups. Complete blood count parameters, C-reactive protein, and troponin values of the whole study group were recorded. Myopericarditis was diagnosed based on acute chest pain, dyspnea, palpitations, heart failure signs, arrhythmia symptoms and ST/T wave change, low voltage, supraventricular tachycardia/ventricular tachycardia on ECG, or elevated troponin T/troponin I levels or functional abnormalities on echocardiography. A comparison of the platelet indices made during diagnosis and 2 weeks after treatment was done for the myopericarditis patients. Results: There was no statistically significant difference in platelet indicies values. However, the increase in platelets and plateletcrit values after the treatment of myopericarditis was statistically significant. This study pointed out that there was a negative correlation between platelet–plateletcrit values and the troponin I–C-reactive protein. Conclusion: We found that platelet count and plateletcrit values increased after treatment. This is important as it is the first study in children to investigate the possible role of platelet indications for myopericarditis in children.

Objective: To investigate the relationship between serum C-reactive protein (CRP) levels and the calculated 10-year Framingham risk score (FRS) in patients newly diagnosed with intermittent claudication. Methods: Serum CRP levels were measured in 90 patients newly diagnosed with intermittent claudication over a 12-month period. In all, 76 patients (53 males [70%], mean age 63.3 ± 9.3) were included in the analysis. Results: Log-transformed CRP levels significantly correlated with total FRS ( r = .34, P = .002). Participants were divided into 4 groups according to log-CRP levels. Analysis of variance showed a statistically significant difference between the 4 groups in terms of mean FRS, P = .003. Post hoc comparisons indicated that group 1 was significantly different from group 4, P = .002. Analysis of covariance showed a significant difference between the 4 groups of log-CRP levels in terms of mean FRS, P = .008. Conclusion: There is an increased 10-year risk of coronary heart disease associated with increased plasma concentration of CRP in patients newly diagnosed with intermittent claudication.

SEPSIS IS ONE OF THE MOST COMMON diagnostic challenges in the NICU. Currently a definitive diagnosis can be made only with the gold-standard blood culture, which is generally not available for 48 hours.1,2 Difficulty obtaining a large enough sample to detect a positive blood culture, as well as increased use of antenatal antibiotics, has complicated the ability to make a definitive diagnosis of sepsis.3 If left untreated, sepsis can increase morbidity and mortality. Therefore, many infants are treated empirically with broad-spectrum antibiotics.4,5 Two kinds of tests would be most helpful in the diagnosis of neonatal sepsis: one that quickly confirms the diagnosis and one that conclusively rules it out. In fact, a diagnostic sepsis marker with a high negative predictive value (the value representing patients without sepsis who are correctly diagnosed) might reduce the short- and long-term adverse effects of antibiotics, health care costs, and length of hospital stay.6 Despite extensive investigation no single test meets the criteria that would make it an ideal marker for the early diagnosis of sepsis in the newborn.5,7,8 Generally, screening includes a complete blood count with differential and may be accompanied by other adjunctive tests such as a C-reactive protein (CRP).9–11 This column examines CRP, an acute phase reactant (APR), as a diagnostic marker for neonatal sepsis.
