ABSTRACT: Excessive infection and inflammation are the most common complications associated with castration. The objective of this study was to compare the efficacy of flunixin meglumine (FM), meloxicam (MX), or firocoxib (FX) for inflammation control after castration in horses using acute-phase proteins (APP) as markers of inflammation. Thirty healthy, unbroken, mixed-breed horses (body weight 358.62±45.57kg and age 4.99±2.63 years) were randomly (n=10 animals/group) allocated to receive one of three different post-castration anti-inflammatory medicines: Group 1 (FM 1.1mg/kg bwt, IV, s.i.d for 5 days); Group 2 (MX 0.6mg/kg bwt, IV, s.i.d for 5 days); and Group 3 (FX 0.1mg/kg bwt, IV, s.i.d for 5 days). All horses were castrated in standing position, using the open technique. Serum and peritoneal APP concentrations were measured by sodium dodecyl sulfate (SDS) polyacrylamide gel electrophoresis (PAGE) and determined before castration (0), and 3, 5, 24, 48, 72, 120 and 168 hours after castration. The results were submitted to analysis of variance using the SAS statistical program, and means were compared by the Student-Newman-Keuls test (p<0.05). Three animals from the MX group developed hyperthermia (with rectal temperatures of 39.8, 39.3 and 38.9°C on day 4, 5 and 6, respectively) and showed local clinical signs of inflammation (inguinal and excessive scrotal edema) and reluctance to walk, as well as a rigid gait of the hind limbs. The same complications were observed in one FX horse. No complications were observed among the FM animals. The castration resulted in significant changes in serum and peritoneal values of total proteins, ceruloplasmin (Cp), transferrin (Tf), albumin (Alb), haptoglobin (Hp) and α1-acid glycoprotein (Gp) in animals of all experimental groups. However, the animals of the MX and FX groups presented more intense acute phase response compared to the animals of the FM group. Changes in the APP were associated with the surgical trauma of castration, but the differences between groups were associated with the ability of the nonsteroidal anti-inflammatory drug to control the inflammation. In conclusion, and based on the findings of acute phase proteins, flunixin is more efficient to control the magnitude of inflammation following castration as compared to meloxicam and firocoxib.

One hundred 6- to 12-month-old Nelore calves were allotted into control group (G1; 50 healthy calves) and photosensitization group (G2; n= 50). Blood samples were collected 12 to 24 hours after the onset of dermatitis (M1), and 15 to 30 days after that (M2), at time of resolution of clinical signs. Serum protein electrophoresis was performed by means of sodium dodecyl sulphate-polyacrylamide gel electrophoresis. Eighteen serum proteins with molecular weights ranging from 16,000 to 189,000 daltons (Da) were identified in all calves. In M1 and M2 serum concentrations of proteins with molecular weights of 115,000Da (ceruloplasmin), 61,000Da (a1-antitrypsin), 45,000Da (haptoglobin), and 40,000Da (acid glycoprotein) were significantly increased in calves. In conclusion, measurement of serum acute phase protein concentrations may be useful in monitoring the progression of bovine hepatogenous photosensitization, including guide probable alteration on therapeutic procedures.

The aim of this study was to correlate the serum levels of acute phase proteins (APPs) and cytokines in response to treatment by various antimicrobial agents in feedlots calves (FL) naturally infected with Mannheimia haemolytica (M. haemolytica) and Histophilus somni (H. somni). 840 feedlot calves in one farm in Al-Kharg region, Saudi Arabia were clinically examined for the presence of respiratory disease manifestations. The infection was confirmed using nasopharyngeal swabs. Blood samples from diseased animals were collected before and after (7 days) treatment for biochemical analysis of serum amyloid A (SAA), haptoglobin (HP) and cytokines tumor necrosis factor alpha (TNF-α), interferon gamma (IFN-γ), interleukin-1 β (IL1β), and interleukin-8 (IL-8). FL that were positive for M. haemolytica and/or H. somni (n=69) received treatment with one antibiotic, including tulathromycin (Tula; n=26 cases), florfenicol (FFC; n=19), tilmicosin (Tm; n=13), or ceftiofur (CEF; n=11) and one non-steroidal anti-inflammatory drug (Flunixin meglumine (FM; n=43) or phenylbutazone (PBZ; n= 26). We demonstrated the selective potent inhibitory effect of the administrated anti-inflammatory agents either FM or PBZ on the production of APPs and pro-inflammatory cytokines in FL infected with bovine respiratory disease (BRD). Our findings showed the antibacterial efficacy of FFC and Tm for the treatment of infected FL when administrated with either FM or PBZ. However, Tula was preferable to administrate in combination with FM for the treatment of FL with respiratory manifestations. Importantly, monitoring the sera level of Hp, IL-1β, and interleukin-8 (IL-8) in feedlots treated with either FM combined with Tula, FFC, or Tm or PBZ combined with FFC, and Tm has been effective in predicting the disease prognosis

ABSTRACT: Use of acute-phase proteins (APPs) for assessment of health and disease in animals has increased greatly within the last decade. The objective was to determine the normal concentration of APPs in the serum and cerebrospinal fluid (CSF) of healthy cattle by polyacrylamide gel electrophoresis. Fifty crossbred animals (350±70kg of BW and 18±1.2 months of age), 25 heifers and 25 steers were used. CSF samples were collected from atlanto-occipital (AO) site and blood samples were obtained from the jugular vein. CSF and serum protein electrophoresis were performed by means of sodium dodecyl sulphate-polyacrylamide gel electrophoresis. Thirty-seven proteins with molecular weights ranging from 7 and 37kDa were identified in CSF of all animals. These eight were nominally identified with immunoglobulin A and G, celuloplasmin, transferrin, albumin, α1-antitripsin, acidic glycoprotein, and haptoglobin. All protein fractions in CSF did not differ between heifers and steers. In sera, 34 proteins with molecular weights between 7 and 244kDa were identified in heifers and steers. Similar proteins were nominally identified in the sera, but only the CSF presented α1-antitripsin. The serum values of acidic glycoprotein and immunoglobulin G were significantly higher in steers compared with heifers. In conclusion, measurement of CSF acute phase protein concentrations can be useful in diagnosing and monitoring the progression of bovine neurological diseases, perhaps even to guide therapeutic procedures. The CSF electrophoretic profile of healthy cattle does not change depending on gender.

Oxidant Status

Dysfunctional inflammation contributes significantly to the pathogenesis of coliform mastitis and the classical pro-inflammatory enzyme cyclooxygenase-2 (COX-2) is the target of medical intervention using the non-steroidal anti-inflammatory drug (NSAID) flunixin meglumine (FM). Inhibition of COX-2 by FM can decrease concentrations of pro-inflammatory fatty acid-based mediators called eicosanoids, providing antipyretic and analgesic effects in dairy cows suffering from coliform mastitis. However, approximately 50% of naturally occurring coliform mastitis with systemic involvement results in death of the animal, even with NSAID treatment. Inadequate antioxidant potential (AOP) to neutralize reactive oxygen species (ROS) produced during excessive inflammation allows for oxidative stress (OS), contributing to tissue damage during coliform mastitis. Biomarkers of lipid peroxidation by ROS, called isoprostanes (IsoP), were used in humans and cattle to quantify the extent of OS. Blood IsoP were shown to be elevated and correlate with oxidant status during acute coliform mastitis. However, the effect of FM treatment on oxidant status and markers of OS has not been established. Blood IsoP concentrations were used to quantify systemic OS, whereas milk was used to assess local OS in the mammary gland. Results indicate that FM treatment had no effect on blood markers of inflammation but reduced the oxidant status index (OSi) by increasing blood AOP from pre- to post-FM treatment. Milk AOP significantly increased from pre- to post-FM treatment, whereas ROS decreased, resulting in a decreased OSi from pre- to post-FM treatment. The only blood IsoP concentration that was significantly different was 5-iso-iPF2α-VI, with a decreased concentration from pre- to post-FM treatment. Conversely, milk 5-iso-iPF2α-VI, 8,12-iso-iPF2α-VI, and total IsoP concentrations were decreased following FM treatment. These results indicated that administration of FM did improve systemic and local oxidant status and reduced local markers of OS. However, differential effects were observed between those animals that survived the infection and those that died, indicating that pre-existing inflammation and oxidant status greatly affect efficacy of FM and may be the key to reducing severity and mortality associated with acute coliform infections. Supplementation to improve AOP and anti-inflammatory mediator production may significantly improve efficacy of FM treatment.

Rotavirus Diarrhea

ABSTRACT The aim of the present study was to characterize changes in acute phase protein levels according to the occurrence of rotavirus diarrhea in calves in the first month of life. Blood and fecal samples were taken before colostrum intake and at 1, 2, 7, 15, 21 and 30 days of age from 24 Holstein calves allotted in three experimental groups: calves that did not present diarrhea (group A), calves that presented diarrhea, but tested negative for rotavirus in feces (group B), and calves that presented diarrhea and tested positive for rotavirus in feces (group C) (experiment 1). When the animals presented episodes of diarrhea, blood and fecal samples were taken at 24-hour intervals until the end of clinical signs (experiment 2). Serum proteins were separated by SDS-PAGE technique and rotavirus in feces was detected by PAGE. Data of experiment 1 were analyzed by ANOVA and Tukey's test, considered significant at P<0.05. Data of experiment 2 were subjected to the HSD test. Total protein, globulins, and IgG concentrations were lower in group C than in groups A and B. Ceruloplasmin and transferrin levels were higher in group C than in groups A and B. Serum concentrations of haptoglobin and α1-acid glycoprotein did not differ significantly between groups throughout the experimental period. Calves presented diarrhea between 10.4 and 14.6 days of age in group B, and between 10.3 and 14.6 days of age in group C. In the moments of diarrhea manifestation, least square means of IgA, haptoglobin and α1-acid glycoprotein concentrations did not differ significantly between groups B and C, but ceruloplasmin and transferrin concentrations were higher in group C than in group B, as opposed to what occurred with IgG levels. These findings show that optimizing passive immunity transfer of immunoglobulins decrease the likelihood of calves developing diarrhea caused by rotavirus. In addition, ceruloplasmin presents characteristics of a biomarker of rotavirus infection in calves.

Abstract Calf bronchopneumonia is complex multifactorial disease and for its accurate diagnosis and therapy, besides clinical examination, microbiologic, hematologic and biochemical analyses could be necessary. In general, additional analyses are not implemented, mainly because the disease biomarkers are not defined. To establish which analysis might be useful for determining the severity of the disease, we analyzed 23 three-month old calves with mild clinical signs of bronchopneumonia and 15 age-matched healthy calves. Pasteurella multocida was isolated from deep nasal swabs of diseased calves. Peripheral blood erythrocyte and leukocyte count of bronchopneumonic and healthy calves showed no difference. Serum proteins, lipoproteins and lipids were analyzed with spectrophotometry, agarose gel electrophoresis, non-reducing SDS-PAGE, gel zymography, and thin-layer chromatography. The bronchopneumonic calves had an increased level of circulating immune complexes and α globulins, which contain some of the positive acute phase proteins. In diseased calves the increased concentration of total γ globulins (IgG), due to an increased concentration of anionic γ globulins (predominately IgG1), was detected. The increased concentration of anionic γ globulins followed by increased concentration of transferrin (negative acute phase protein) and HDL cholesterol, decreased concentration of LDL-cholesterol, unchanged activity of matrix metalloproteases and leukocyte counts might reflect the obvious absence of generalized inflammation. A positive correlation was found between the acquired results and the appearance of mild clinical signs. Therefore, we believe that the parameters analyzed in the peripheral blood could be applied as reliable disease markers to distinguish between severe (inflammatory) and mild forms of calf bronchopneumonia and to predict a better outcome for these calves.

The present study aimed to assess potential changes in acute phase proteins in sheep experimentally infected with Trypanosoma vivax. There were studied eight male sheep, four used as controls and four infected with 10(5) T. vivax trypomastigotes. Blood samples were collected at two points times before infection and then at 5,7, 9, 11, 13, 15, 20, 30, 45, 60, 75, 90, 105 and 120 days post-infection (dpi). Blood samples were centrifuged and allotted, and acute phase proteins were then separated by electrophoresis on acrylamide gel containing sodium dodecyl sulfate. Protein concentrations were determined by computer-assisted densitometry. Total protein was determined by colorimetric biuret method. Trypanosomes were counted daily using a 5 mL aliquot of blood smear on a glass slide under a 22 × 22 mm coverslip. Parasites were counted in 100 microscopic fields (40× magnification), and then multiplied by a correction factor. The results were expressed as parasites per mL of blood. For statistical analyses, we used the Wilcoxon test at 5% significance level. There was found a reduction in several acute phase proteins and increase in antitrypsin and transferrin. This finding can be used for the diagnosis of T. vivax infection, especially in chronic infection.

The metabolic response to surgical trauma is mainly characterised by an increase in BMR, a negative N balance, increased gluconeogenesis and increased synthesis of acute-phase proteins. These reactions aim at ensuring the availability of endogenous substrates for healing wounds while the synthesis of acute-phase proteins enhances the scavenging process and helps repair. However, if this process is excessive or continues for too long, it leads to a progressive depletion of body compartment with a consequent adverse outcome. Obviously, the severity of such depletion is magnified if the patient is starving or is already malnourished and the consumption of lean body mass is not compensated by an exogenous supply of nutrients. The nutritional control of this metabolic reaction represents the traditional rationale for nutritional support of surgical patients. Subsequent data have shown that the negative effects of starvation are not simply due to the starvation per se but due to the starving gut, and peri-operative enteral nutrition has proven successful in blunting the metabolic response after injury and improving protein kinetics, net balance and amino acid flux across peripheral tissue and consequently in decreasing the complications. Finally, further clinical research has shown that many post-operative infections may result from immune suppression and that such state might be reversed to some degree by modulation of the immune response through specialised nutritional support in surgical patients, regardless of their nutritional status. This paper will focus on the updated evidence-based research on peri-operative nutrition (parenteral, enteral and immune-enhancing) in patients undergoing major surgery.

Objectives The aim of this study was to characterise the response of acute phase proteins (APPs) in cats seropositive for Dirofilaria immitis and to its endosymbiont bacterium Wolbachia. Methods The APPs serum amyloid A (SAA), haptoglobin (Hp) and ceruloplasmin (Cp) were measured in 25 seropositive cats and in 16 healthy seronegative cats. Results SAA and Cp concentrations were significantly higher in animals with D immitis seropositivity that exhibited clinical signs related to the disease, and Hp was elevated in all D immitis-seropositive animals. There was no significant correlation between APPs and D immitis or Wolbachia species antibody titres. Conclusions and relevance An association between feline seropositivity to D immitis and APP response was demonstrated. Increases in serum SAA and Cp concentrations were related to D immitis-associated clinical signs, whereas Hp increased in all seropositive animals.
