OBJECTIVE: To develop and validate a time-resolved immunofluorometric assay (TR-IFMA) for measurement of C-reactive protein (CRP) in canine whole blood. ANIMALS: 12 healthy dogs and 35 dogs with inflammatory processes. PROCEDURE: CRP was isolated from acute-phase serum by affinity chromatography and used as a standard for calibration. Analytic and functional limit of detection and intra-assay and interassay precision were calculated. Accuracy was evaluated by recovery assays and by comparison with results of a commercial ELISA. Correlation between CRP concentrations in whole blood and corresponding plasma fractions was tested by use of TR-IFMA. Stability of blood samples at 4 degrees C was assessed during a 1-month period, and effects of anticoagulants were evaluated. Measurements of CRP in blood samples from 12 healthy dogs were compared with those of 35 dogs with inflammatory diseases. RESULTS: Analytic and functional limits of detection were 0.53 and 3.26 microg/mL, respectively. Intra-assay and interassay coefficients of variation varied between 2.1% to 8.9% and 8.0% to 12.3%, respectively. Mean recoveries of added CRP were 104% and 114%. Measurements of CRP by use of TR-IFMA and ELISA were highly correlated (R2 = 0.97). Measurements of CRP in whole blood and in corresponding plasma fractions by use of TR-IFMA were also highly correlated (R2 = 0.97). Neither storage nor use of anticoagulants disturbed measurement of CRP concentrations in whole blood. Concentrations of CRP in whole blood of dogs with inflammation were significantly higher than in healthy dogs. CONCLUSIONS AND CLINICAL RELEVANCE: Determination of CRP concentrations in whole blood may provide a diagnostic test for inflammation in dogs.  相似文献

A time-resolved immunofluorometric assay (TR-IFMA) was developed for the determination of C-reactive protein (CRP) in canine serum. CRP was isolated from canine acute-phase serum by affinity chromatography on agarose coupled with phosphorylethanolamine. This isolated dog CRP was used as standard to calibrate the assay. Intra-assay and inter-assay coefficients of variation were in the ranges 5.3–7.1% and 4.8–13.3%, respectively. Accuracy, evaluated by adding 2 and 10 μg/ml of CRP to serum samples, provided recoveries of 99.9% and 106.8%. High correlation was found between CRP measurements by TR-IFMA and a by commercial enzyme-linked immunosorbent assay (R2 = 0.98). The limit of detection for the TR-IFMA method was 0.000067 μg/ml and the measurement of CRP in serial dilutions of acute-phase dog sera generated curves with the same slope as the one constructed with purified CRP. The TR-IFMA provides a precise, accurate and highly sensitive assay for CRP determination in dog samples. CRP levels in dogs with different diseases ranged between 10.2 and 210.7 μg/ml and were significantly higher than those observed in healthy dogs (< 7.1 μmg/ml).  相似文献

OBJECTIVE: To determine the characteristics of an automated canine C-reactive protein (CRP) assay and evaluate 2 human CRP assays for use in dogs. Animals-56 client-owned dogs with pyometra and 11 healthy control dogs. PROCEDURES: Samples from 11 dogs with high (> 100 mg/L) or low (< 10 mg/L) CRP concentrations (determined by use of a canine ELISA) were evaluated by use of the automated canine CRP assay. Intra- and interassay imprecision was determined (by use of those 2 plasma pools), and assay inaccuracy was assessed by use of logistic regression analysis of results obtained via ELISA and the automated canine CRP assay. Two automated human CRP assays were used to measure plasma CRP concentration in 10 dogs. RESULTS: By use of the ELISA, mean +/- SD plasma CRP concentration was 96.1 +/- 38.5 mg/L and 10.1 +/- 23.2 mg/L in dogs with pyometra and control dogs, respectively. The automated canine assay had intra-assay coefficients of variation (CVs) of 7.8% and 7.9%, respectively, and interassay CVs of 11.1% and 13.1%, respectively. Results from the automated assay were highly correlated with results obtained via ELISA. The human assay results did not exceed 0.4 mg/L in any dog. CONCLUSIONS AND CLINICAL RELEVANCE: The automated canine CRP assay had less interassay imprecision, compared with the ELISA. The 2 human CRP assays were not suitable for analysis of canine plasma samples. The automated canine CRP assay was more precise than the ELISA for serial evaluations of plasma CRP concentration in dogs.  相似文献

Background: Serum C-reactive protein (CRP) is an acute phase marker in dogs that is useful for the diagnosis and monitoring of inflammatory disease. Rapid, reliable, and automated assays are preferable for routine evaluation of canine serum CRP concentration.
Objective: The aim of this study was to evaluate whether canine serum CRP concentration could be measured reliably using an automated turbidometric immunoassay (TIA) designed for use with human serum.
Methods: A commercially available TIA for human serum CRP (Bayer, Newbury, UK) was used to measure canine serum CRP concentration. Cross-reactivity of antigen was evaluated by the Ouchterlony procedure. Intra-and interassay imprecision was investigated by multiple measurements on canine serum samples and serum pools, respectively. Assay inaccuracy was investigated by linearity under dilution and comparison of methodologies (canine CRP ELISA, Tridelta Development Ltd, Kildare, UK). Then the assay was applied to serum samples from 14 clinically healthy dogs, 11 dogs with neoplasia, 13 with infections, 8 with endocrine or metabolic diseases, and 10 with miscellaneous diseases.
Results: Cross-reactivity between canine serum CRP and the anti-human CRP antibody was found. Intra-and interassay imprecision ranged from 5.2% to 10.8% and 3.0% to 10.2%, respectively. Serum CRP concentration was measured in a linear and proportional manner. There was no significant disagreement and there was linear correlation of the results in the comparison of methodologies, except for a slight proportional discrepancy at low CRP concentrations (<10 μg/mL). Dogs with infections had a significantly higher concentration of serum CRP than did all other dogs, and dogs with neoplasia had a significantly higher concentration of serum CRP than did clinically healthy dogs.
Conclusions: Canine serum CRP concentration can be measured reliably using the commercially available TIA designed for human CRP.  相似文献

A time-resolved immunofluorometric assay (TR-IFMA) was developed for the determination of haptoglobin (Hp) in canine serum. Haptoglobin was purified from canine acute phase serum by ammonium sulphate precipitation followed by gel filtration. This isolated dog Hp was used as the standard to calibrate the assay. Intra- and inter-assay coefficients of variation of the assay were, respectively, 5.7% and 16.6% at 0.51 mg/mL, 2.4% and 10.6% at 2.1 mg/mL and 10.5% and 11.9% at 32.5 mg/mL. The dilution of serum samples with high Hp concentrations resulted in linear regression equations with R2 of 0.99 and 0.97. A high correlation was found in serum Hp measurements by TR-IFMA and a commercial assay based on peroxidase activity of haemoglobin bound to haptoglobin (R2 = 0.96). The limit of detection for the TR-IFMA method was 0.002 microg/mL. The addition of fresh haemolysate to serum samples did not affect the haptoglobin concentration (P = 0.694). Statistical differences (P < 0.003) were found between healthy dogs and dogs with different pathological processes. In whole blood, Hp concentrations were much lower than in serum but closely related (R2 = 0.84) whereas saliva Hp concentrations were poorly related with serum concentrations (R2 = 0.53). However, the concentration of Hp in saliva was significantly (P < 0.039) higher in dogs with pathological processes compared to healthy dogs. The assay sensitivity was adequate to also be applied to whole blood and saliva specimens.  相似文献

The objective was to evaluate independently the reliability of a commercially available canine serum interleukin-10 (IL-10) enzyme-linked immunoassay (ELISA) and to investigate canine serum IL-10 concentrations in healthy dogs, in dogs with a naturally-occurring acute phase reaction and in dogs following surgical stimulus by assessing intra- and interassay imprecision, inaccuracy and detection limits. Median (and range) serum IL-10 concentrations (ng/L) in the various groups were as follows: healthy dogs (n=15), 18.9 (11.2-71.5); dogs with pyometra (n=9), 37.9 (12.4-201.8); dogs with angiostrongylosis (n=8), 20.29 (14.3-108.7) and values in dogs following surgical stimulus (n=15), 14.8 (10.7-65.8). The assay measured canine serum IL-10 reliably (intra- and interassay imprecision 4.9-8.3% and 9.9-10.9%, respectively; detection limit 10.7 ng/L with no significant inaccuracy). No significant increases in IL-10 were observed following surgical stimulus and no difference in IL-10 was observed between the diagnostic groups. IL-10 values showed a higher degree of variation in dogs with an inflammatory response, i.e. those with elevated serum C-reactive protein (CRP) concentrations, compared to healthy dogs. As anticipated, healthy dogs had low levels of both analytes, whereas dogs with an acute phase response had IL-10 levels with no clear relationship to CRP concentrations, with observed low IL-10 values even when there was a marked inflammatory response.  相似文献

The purpose of this study was to evaluate a commercially available enzyme-linked immunosorbent assay for determination of canine serum C-reactive protein (CRP). The concentration of CRP could be determined accurately and the intra- and inter-assay coefficients of variation were in the range of 6.9-10.1 and 7.5-29.0%, respectively. This level of imprecision between runs is usually considered unacceptable for diagnostic purposes, but the overall results indicated that the assay was useful in differentiating dogs suffering from infections, from dogs suffering from various other diseases (neoplastic diseases, endocrine/metabolic disorders), and healthy dogs. The assay was also able to detect dynamic changes of CRP during development and after cessation of spontaneous occurring inflammatory stimuli in two clinical cases.  相似文献

The concentration of C-reactive protein (CRP) was measured in effusions from 50 dogs to assess the potential for measuring this protein to differentiate body cavity fluids. The effusions were classified as either transudates, modified transudates or exudates according to their total protein concentration, total nucleated cell count, cytological findings and aetiology, and the concentration of CRP was determined by a time-resolved immunofluorometric assay. There were significant differences between the concentrations of CRP in the three types of effusion; the highest concentrations were observed in the exudates (4.47 to 54.59 microg/ml), the lowest were in the transudates (0.0094 to 7.87 microg/ml), and the modified transudates contained intermediate concentrations of CRP (0.045 to 10.78 microg/ml). A cut-off value of 4 microg/ml had a sensitivity of 100 per cent and a specificity of 94.4 per cent for differentiating transudates from exudates, and a cut-off value of 11 microg/ml had a sensitivity of 88.2 per cent and a specificity of 100 per cent for distinguishing modified transudates from exudates. However, a cut-off value of 1 microg/ml had a lower sensitivity (80 per cent) and an unacceptably low specificity (66.7 per cent) for differentiating transudates from modified transudates.  相似文献

A time-resolved immunofluorometric assay was evaluated for measurement of C-reactive protein in meat juice from diaphragmatic muscle collected from slaughtered pigs. Analytical and clinical validation of the method was performed by using meat juice samples, obtained by freezing and thawing muscle pieces. The intra- and inter-assay coefficients of variation ranged from 2.2-5.8% to 7.9-14.3%, respectively. The limit of detection was 0.00038 microg/ml. The method measured the CRP concentrations in a linear manner with a good accuracy (r=0.99). CRP concentrations in serum were highly correlated with those in diaphragmatic meat juice (r=0.90; p<0.001). CRP concentrations were significantly higher in clinically affected pigs compared to non-diseased pigs. The assay described here provides a sensitive method for measuring CRP concentrations in meat juice, which can represent a suitable alternative to serum or blood samples and simplifies the process of sampling collection at slaughter.  相似文献

High-mobility group box 1 (HMGB1), a nonhistone chromosomal protein, has recently been suggested as a late mediator of the inflammatory cascade. Blood HMGB1 levels are increased in a number of human diseases, and HMGB1 has been suggested to be a useful marker for disease severity and prognosis. The objective of this study was to assess the clinical usefulness of HMGB1 in dogs. Plasma HMGB1 levels, as well as C-reactive protein (CRP), a typical canine inflammatory marker, were measured in dogs with various diseases, especially systemic inflammatory response syndrome (SIRS), and dogs that had undergone surgery. HMGB1 gradually increased and attained a maximum level 72 hr after surgery, whereas CRP increased rapidly, peaking at 24 hr. Although both HMGB1 and CRP levels were significantly increased in dogs with various diseases compared with the control dogs, no correlation was found between the HMGB1 and CRP values. HMGB1 levels in the SIRS group were significantly elevated compared with those in the non-SIRS group. However, the increase in HMGB1 levels above the reference range was not indicative of SIRS. Instead, the presence of increased HMGB1 and CRP levels above the reference ranges significantly affects the poor outcome of SIRS. The present study indicates that HMGB1 is a novel canine inflammatory marker and is distinct from CRP. However, the additional clinical value of HMGB1 measurement remains unclear, and further studies are warranted.  相似文献

The concentrations of C-reactive protein (CRP), serum amyloid A, haptoglobin (Hp) and α(1)-acid glycoprotein were measured in dogs with clinical signs of nasal disease and compared with those of healthy dogs in order to determine the expression of these proteins in cases of canine nasal disease. A significant difference (P<0.001) between the symptomatic group and the control group was found for both CRP and Hp. Among the animals with nasal disease, a significant intergroup difference (P<0.05) was found in the expression of Hp between dogs with aspergillosis and those with chronic rhinitis.  相似文献

The purpose of the study reported here was to determine whether dogs with chronic valvular disease have increased plasma C-reactive protein concentration, compared with that in clinically normal dogs. Blood was collected from 47 dogs with physical and echocardiographic evidence of chronic valvular disease and from 20 healthy controls. C-reactive protein concentration was determined with a commercial canine C-reactive protein enzyme immunoassay. Compared with controls, dogs with chronic valvular disease had higher plasma concentration of C-reactive protein (median 2.17 microg/mL [range, 0.86-33.8 microg/mL]) versus 1.43 microg/mL [range, 0.84-4.99 microg/mL]; P < .001). C-reactive protein concentration was not related to the presence of congestive heart failure or murmur grade. The results of this study suggest that increased concentration of C-reactive protein is found in dogs with chronic valvular disease.  相似文献

Background: 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. Objectives: 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. Methods: 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. Results: 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. Conclusions: 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.  相似文献

OBJECTIVES: To evaluate the clinical utility of serum tumour necrosis factor-alpha, C-reactive protein and microalbuminuria as disease activity markers in canine idiopathic inflammatory bowel disease. METHODS: Dogs with chronic gastrointestinal disease for which no underlying cause could be identified were considered to have idiopathic inflammatory bowel disease and were included in the study. Serum tumour necrosis factor-alpha was assessed using a canine-specific ELISA, C-reactive protein by immunoturbidometric assay and quantitative microalbuminuria was analysed using a monoclonal antibody directed against canine albumin. The canine inflammatory bowel disease activity index and histopathologic grade were used to assess disease severity; biologic markers were then compared with the canine inflammatory bowel disease activity index and histopathologic grade. RESULTS: Sixteen dogs were included in the study. C-reactive protein level was mildly elevated in 15 dogs. Microalbuminuria was elevated in two of 15 dogs, and tumour necrosis factor-alpha was not detected in any dog tested. No correlation was found between the canine inflammatory bowel disease activity index and C-reactive protein or microalbuminuria or between histopathologic grade and C-reactive protein or microalbuminuria. There was no correlation between histopathologic grade and the canine inflammatory bowel disease activity index. CLINICAL SIGNIFICANCE: Although only a small number of dogs were evaluated, this study does not support the use of serum tumour necrosis factor-alpha measured by canine-specific ELISA or microalbuminuria in the evaluation of disease activity in dogs with idiopathic inflammatory bowel disease. Although mildly elevated in most dogs, C-reactive protein did not reflect disease severity as assessed by the canine inflammatory bowel disease activity index or histopathologic grade.  相似文献

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 < or = 0.05). Serum CRP concentrations were lower in obese dogs than in controls (P < or = 0.001). C-reactive protein was negatively correlated with insulin/glucose ratio (R = -0.42) and cholesterol (R = -0.39; P < or = 0.05). Furthermore, levels of cholesterol, triglycerides, and fructosamine were increased in the 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.  相似文献

An immunoturbidimetric assay for canine C-reactive protein   总被引：2，自引：0，他引：2  
Antiserum was raised in sheep against canine C-reactive protein (CRP) and antibody, which was not specific for CRP, was removed by absorption with normal canine serum protein linked to agarose beads. The antiserum was used to develop an immunoturbidimetric assay for canine CRP on a MIRA (Roche Diagnostics) automated clinical biochemical analyser and assessed for routine analysis of CRP in canine serum samples. The assay gave standard curves with each standard having a coefficient of variance (CV) between 4.8 and 11%, interassay CVs below 11% and intra-assay CVs of less than 5%. Parallel dilution curves were obtained with purified CRP diluted in buffer and with endogenous CRP in serum diluted with buffer or with a serum with a negligible CRP content. The immunoturbidimetric assay results correlated with the results obtained using an ELISA method, r=0.88. The immunoturbidimetric assay of canine CRP proved to be suitable for the routine analysis of canine CRP.  相似文献

OBJECTIVE: To determine sensitivity and specificity of assays of D-dimer concentrations in dogs with disseminated intravascular coagulation (DIC) and healthy dogs and to compare these results with those of serum and plasma fibrin-fibrinogen degradation product (FDP) assays. ANIMALS: 20 dogs with DIC and 30 healthy dogs. PROCEDURE: Semi-quantitative and quantitative D-dimer concentrations were determined by use of latex-agglutination and immunoturbidometry, respectively. Fibrin-fibrinogen degradation products were measured by use of latex-agglutination. A reference range for the immunoturbidometric D-dimer concentration assay was established; sensitivity and specificity of the assay were determined at 2 cutoff concentrations (0.30 microg/ml and 0.39 microg/ml). RESULTS: Reference range for the immunoturbidometric D-dimer concentration assay was 0.08 to 0.39 microg/ml; median concentrations were significantly higher in dogs with DIC than in healthy dogs. Latex-agglutination D-dimer and serum and plasma FDP assays had similar sensitivity (85 to 100%) and specificity (90 to 100%); the immunoturbidometric assay had lower specificity (77%) at the 0.30 microg/ml cutoff and lower sensitivity (65%) at the 0.39 microg/ml cutoff. Sensitivity or specificity of the latex-agglutination D-dimer assay was not significantly improved when interpreted in series or parallel with FDP assays. CONCLUSIONS AND CLINICAL RELEVANCE: Measurement of D-dimer concentrations by latex-agglutination appears to be a sensitive and specific ancillary test for DIC in dogs. Specificity of D-dimer concentrations in dogs with systemic disease other than DIC has not been determined, therefore FDP and D-dimer assays should be performed concurrently as supportive tests for the diagnosis of DIC in dogs.  相似文献

C-reactive protein (CRP) is an acute phase protein, which is used to evaluate and monitor the response of the innate immune system to a variety of inflammatory processes in the dog. The purpose of this study was to analytically validate a point-of-care assay (IDEXX Catalyst CRP Test) and an immunoturbidimetric assay (Gentian Canine CRP Immunoassay) for the measurement of serum CRP concentrations in dogs. These 2 assays (Catalyst, Gentian) were compared to a previously validated enzyme-linked immunosorbent assay (Tridelta Development EIA Canine CRP Assay). Linearity, precision, reproducibility, and accuracy were assessed using leftover serum samples. Agreement between assays was assessed using leftover serum samples and serum from clinically healthy dogs. Observed to expected ratios (O/E) for dilutional parallelism were 83.9 to 163.1% and 108.3 to 160.6% for the Catalyst and the Gentian assays, respectively. Coefficients of variation for intra-assay variability ranged from 6.4 to 9.5% for the Catalyst assay and 1.5 to 2.6% for the Gentian assay. Coefficients of variation for inter-assay variability ranged from 3.8 to 18.2% for the Catalyst assay and 4.5 to 5.8% for the Gentian assay. The mean O/E for recovery were 97.9% and 98.5% for the Catalyst and Gentian assays, respectively. Correlations between assays were as follows: Catalyst and Tridelta (R2 = 0.76), Gentian and Tridelta (R2 = 0.79), and Catalyst and Gentian (R2 = 0.98). The Catalyst and Gentian assays are both acceptable for measuring CRP in dog serum, but their results are not directly comparable with the Tridelta assay.  相似文献

Background: In veterinary medicine, there is increasing interest in measuring C‐reactive protein (CRP) as a tool for diagnosis and monitoring of inflammatory diseases. Reported CRP concentrations for healthy dogs have ranged from 0 to 8.9 mg/L. Objectives: The aims of this study were to evaluate a canine‐specific point‐of‐care (POC) lateral flow immunoassay for qualitative CRP measurement in healthy and diseased dogs and to compare results with those obtained by a quantitative ELISA. Methods: Blood samples from 73 client‐owned dogs were available for testing: 16 healthy dogs and 57 dogs with a variety of infectious, inflammatory, or neoplastic diseases. CRP was measured in heparinized whole blood samples and serum with the TECOmedical Dog CRP‐visual POC test. A red line develops in the POC device if CRP is ≥5 mg/L, and results are scored as negative or positive. An ELISA validated previously for canine serum was used as the reference method. Results: For all dogs, serum CRP concentrations measured by the ELISA ranged from 0.1 to ≥350 mg/L (median=38 mg/L). Percentages of the CRP POC test results that agreed with the ELISA results were 98.6% for whole blood and 97.3% for serum samples. For serum samples, sensitivity of the POC test was 96.4% and specificity was 81.3%. For whole blood, sensitivity was 94.7% and specificity was 93.8%. Conclusions: The POC test had very good agreement with the ELISA test and had high sensitivity and specificity; therefore, it can be used as a qualitative test to screen for increases in CRP concentrations.  相似文献

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 agreement were observed between the 2 markers. However, SAA showed a wider range of concentrations and a significantly superior overall diagnostic performance compared with CRP.  相似文献
