Objective: To determine the frequency of the systemic inflammatory response syndrome (SIRS) in canine pyometra and to evaluate the relationship between C‐reactive protein (CRP), tumor necrosis factor α (TNFα), interleukin‐6 (IL‐6), and SIRS. Design: Prospective clinical study. Setting: Veterinary teaching hospital. Animals: Fifty‐three clinical cases of canine pyometra and 19 healthy control bitches. Interventions: Upon admission to the veterinary hospital, history and physical examination findings, including previously defined clinical SIRS parameters, were documented. Blood samples were obtained for hematology and biochemical tests and for CRP, TNFα, and IL‐6 analysis. The diagnosis of pyometra was confirmed by histopathology of the uterus after ovariohysterectomy. After surgery, clinical SIRS parameters, length of hospitalization, and mortality were recorded. Measurements and main results: Pyometra dogs were grouped as SIRS positive (30/53; 57%) or SIRS negative (23/53; 43%). Logistic regression showed that CRP was the only parameter that significantly related to SIRS apart from the clinical criteria that define this syndrome. The mortality rate was low (2/53; 3.8%), and conclusions regarding association with SIRS could not be drawn. A positive SIRS status, high plasma CRP concentration, and high body temperature were variables that related to increased morbidity reflected by the length of hospitalization. Conclusions: SIRS was seen in 57% of canine pyometra cases and a positive SIRS status showed a positive association with prolonged hospitalization. The mortality rate was low (3.3%) among SIRS positive dogs, indicating that progression to multiple organ dysfunction syndrome (MODS) rarely occurs in surgically treated cases of pyometra. CRP was associated with SIRS and with prolonged hospitalization. Further studies of plasma CRP may be warranted in canine intensive care cases susceptible to development of SIRS and MODS.  相似文献

Objective: The objective of this article is to review the human and veterinary literature and provide evidence for the potential beneficial effects of intravenous (IV) lidocaine hydrochloride in preventing post‐ischemic–reperfusion injury, the systemic inflammatory response syndrome (SIRS), and subsequent multiple organ dysfunction syndrome (MODS). Human data synthesis: Lidocaine is a local anesthetic and antiarrhythmic agent that has been used for years in human and veterinary medicine for the treatment of ventricular dysrhythmias associated with blunt cardiac trauma, myocardial ischemia, and cardiac surgery. More recently, the drug has been touted as a scavenger of reactive oxygen species (ROS), and has been used to prevent reperfusion dysrhythmias after treatment of myocardial infarction, cross‐clamping of the aorta, and in trauma medicine. Veterinary data synthesis: Although no clinical experiments with prophylactic intravenous lidocaine exist in veterinary medicine, there is a large body of evidence from experimental animals that support the use of lidocaine as a Na+/Ca2+ channel blocker, superoxide and hydroxyl radical scavenger, inflammatory modulator, and potent inhibitor of granulocyte functions. Lidocaine is being used in some clinical situations in an attempt to prevent the SIRS in veterinary trauma patients. a,b, a,b Conclusions: A large body of experimental evidence exists supporting the use of lidocaine as an anti‐oxidant and inflammatory modulator useful in preventing reperfusion injury. With the lack of cost‐effective and safe treatments for reperfusion injury in veterinary and human trauma medicine, the use of IV lidocaine to prevent the ensuing inflammatory response and MODS makes it an attractive addition to existing treatments. Therefore, it is essential that prospective clinical trials involving lidocaine as a treatment for prevention of reperfusion injury be performed in companion animals to demonstrate its safety and efficacy.  相似文献

Objective: To review the clinical and pathophysiologic aspects of acute respiratory distress syndrome (ARDS) in dogs and cats. Data sources: Data from human and veterinary literature were reviewed through Medline and CAB as well as manual search of references listed in articles pertaining to acute lung injury (ALI)/ARDS. Human data synthesis: Since the term ARDS was first coined in 1967, there has been a abundance of literature pertaining to this devastating syndrome in human medicine. More complete understanding of the complex interactions between inflammatory cells, soluble mediators (e.g., tumor necrosis factor, interleukin (IL)‐6, IL‐8, platelet activating factor) and the clinical patient has provided for timely recognition and mechanistically based protective strategies decreasing morbidity and mortality in human patients with ARDS. Veterinary data synthesis: Although little is known, ARDS is becoming a more commonly recognized sequela in small animals. Initial case reports and retrospective studies have provided basic clinical characterization of ARDS in dogs and cats. Additionally, information from experimental models has expanded our understanding of the inflammatory mechanisms involved. It appears that the inflammatory processes and pathologic changes associated with ARDS are similar in dogs, cats, and humans. Conclusions: Unfortunately, current mortality rates for ARDS in small animals are close to 100%. As our capability to treat patients with advanced life‐threatening disease increases, it is vital that we develop a familiarity with the pathogenesis of ARDS. Understanding the complex inflammatory interactions is essential for determining effective preventative and management strategies as well as designing novel therapies for veterinary patients.  相似文献

Objective: To review the human and veterinary literature on the physiological role and effects of therapeutic albumin supplementation. Data sources: Data from human and veterinary literature was reviewed. Human data synthesis: Hypoalbuminemia often occurs in a variety of critical illnesses, and contributes to the development of life‐threatening complications, including pulmonary edema, delayed wound healing, feeding intolerance, hypercoaguability, and multiple organ dysfunction. Serum albumin concentration has been used as a prognostic indicator in cases of chronic hypoalbuminemia. The use of albumin replacement therapy in humans is sometimes controversial, but may be associated with improved morbidity and decreased mortality. Veterinary data synthesis: Unlike human literature, there is a paucity of controlled clinical studies in the literature regarding albumin supplementation in veterinary patients. Rather, the majority of published studies were performed in experimental animals or via retrospective analyses. One recent study evaluated the use of plasma to improve albumin concentration in dogs with hypoalbuminemia. Other older studies investigated wound healing in dogs with experimentally induced hypoalbuminemia. As in human medicine, serum albumin concentration may be helpful as a prognostic indicator in critically ill dogs. Conclusion: Albumin is one of the most important proteins in the body because of its role in maintenance of colloid oncotic pressure, substrate transport, buffering capacity, as a mediator of coagulation and wound healing, and free‐radical scavenging. Albumin replacement in veterinary medicine is difficult, but until prospective clinical trials determine the efficacy of albumin replacement are conducted, a suggested clinical guideline would be to maintain albumin concentration at or above 2.0 g/dl utilizing fresh frozen plasma.  相似文献

Clinical observations of Babesia canis infection in 63 dogs during a 1-year period are summarised, demonstrating the pathogenicity of the Babesia strain endemic in Hungary. Most patients had babesiosis in the spring and autumn, correlating with the seasonal activity of ticks. Male animals appeared in higher numbers, probably due to an overrepresentation of outdoor dogs. Uncomplicated babesiosis was diagnosed in 32 cases. The disease affected dogs of any age in this study. Symptoms were similar to those published from other parts of the world: lethargy, fever, splenomegaly, pallor, icterus, haemoglobinuria and presence of ticks were the most common observations. Thrombocytopenia, lymphopenia and neutropenia were frequent haemogram changes. Imidocarb appeared to be highly effective in eliminating the Babesia infection. Thirty-one animals demonstrated babesiosis with complications. Most Rottweilers (7/9) developed complicated disease. Old age was a risk factor for multiple complications. Multiple organ manifestations had poor prognosis. Hepatopathy (44%), pancreatitis (33%), acute renal failure (ARF; 31%) and disseminated intravascular coagulation (DIC; 24%) were frequent complications, while immune-mediated haemolytic anaemia (IMHA; 10%), acute respiratory distress syndrome (ARDS; 6%) and cerebral babesiosis (3%) were rarely observed. There was a significant difference between the mean age of dogs having uncomplicated disease, babesiosis with a single complication and babesiosis with multiple complications (3.4, 4.8 and 8.6 years, respectively, p < 0.001). The recovery rate (78, 68 and 25%, respectively, p = 0.005) and mortality rate (3, 21 and 67%, respectively, p < 0.001) also tended to differ significantly in these groups. Systemic inflammatory response syndrome (SIRS) and DIC are two possible pathways leading to multiple organ dysfunction syndrome (MODS) in babesiosis. DIC was found to predict MODS more sensitively in this study than SIRS: there were 6 animals developing MODS out of 11 identified with DIC, while only 5 dogs developed MODS out of 22 having SIRS.  相似文献

Hemolytic Uremic Syndrome in Dogs   总被引：1，自引：1，他引：0  
A disease syndrome similar to the hemolytic uremic syndrome of people is described in three dogs with acute renal failure. In each dog, hemorrhagic gastroenteritis preceded the onset of anuric acute renal failure. Evidence of microangiopathic hemolytic anemia (schizocytes, thrombocytopenia, and increased concentrations of fibrin split products) was present in the three dogs. Serum chemistry results showed increased concentrations of blood urea nitrogen, creatinine, and phosphorus. Ultrasound examination performed in one dog revealed increased echogenicity of the renal cortices. Treatment for anuric acute renal failure using a continuous dopamine and furosemide infusion established urine production in one of three dogs. Microscopic examination of tissue from the two dogs that underwent necropsy showed occlusion of the renal vasculature by fibrin thrombi consistent with microangiopathic arteriolar thrombosis. The pathophysiology and current knowledge of human hemolytic uremic syndrome is compared with hemolytic uremic syndrome in these dogs. (Journal of Veterinary Internal Medicine 1993; 7:220–227.

Reasons for performing study: The post operative response of the large colon wall after a surgically corrected large colon volvulus (LCV) has not been investigated. Objectives: To use transabdominal ultrasound to monitor the post operative change in large colon wall thickness following surgical correction of LCV. Hypothesis: A prolonged period to colon wall involution is correlated with an increased rate of post operative morbidity and mortality. Methods: A prospective clinical study including horses that presented to the North Carolina State University Veterinary Teaching Hospital for colic between September 2006 and March, 2008, had surgically diagnosed and corrected LCV (at least 360°) without resection and recovered from anaesthesia. Ultrasound of the ventral large colon was performed at the time of anaesthetic recovery and every 6–8 h until the colon wall returned to normal thickness (≤5 mm). Outcome was evaluated using a one‐way ANOVA to compare average time to colon wall involution between: 1) survivors and nonsurvivors; and 2) horses that developed multiple organ dysfunction syndrome (MODS) during the post operative period and those that recovered without evidence of MODS. Results: Sixteen horses that recovered without evidence of MODS had a significantly shorter period to colon wall involution (≤5 mm) compared to those diagnosed with MODS (mean ± s.e. 19.6 h ± 2.5 and 39.7 h ± 6.7 respectively, P = 0.006). There was no significant difference in mean period to colon wall involution between survivors and nonsurvivors (26.2 ± 4.9 and 33.2 ± 7.8 h, respectively). Conclusions: A shorter time to colon wall involution was associated with decreased post operative morbidity in horses presented for surgical correction of large colon volvulus without resection. Potential relevance: Ultrasonographic monitoring of colon wall involution after surgical correction of LCV may aid in identifying those cases at risk of MODS. Further investigation of colon wall involution time using a larger number of horses is warranted.  相似文献

Standardized assessment of response to therapy for lymphoma in dogs is lacking, making critical comparisons of treatment protocols difficult. This Veterinary Cooperative Oncology Group (VCOG) consensus document, based on the recommendations of a subcommittee of ACVIM board-certified veterinary oncologists, was unanimously adopted at the 29th Annual Conference of the Veterinary Cancer Society (VCS) by the VCOG membership. It has integrated guidance from the response assessment criteria established for lymphoma in human patients using standards available in routine veterinary oncology practices that are simple, repeatable and consistently applicable. These guidelines are intended only for use in dogs, where peripheral lymphadenopathy represents the principal component of their disease and as such do not critically assess extranodal disease (e.g., primary cutaneous, central nervous system, gastrointestinal). It is hoped these guidelines will be widely adopted and serve to facilitate the comparison of current and future treatment protocols used in the therapy of dogs.  相似文献

Objective: To review the available endpoints of shock resuscitation, including traditional perfusion parameters, oxygen‐transport variables, lactate, base deficit (BD), venous oxygen saturation, and gastric mucosal pH, and to discuss the currently accepted methods of assessing successful reversal of oxygen (O2) debt in shock patients. Human‐based studies: Early goal‐directed therapy has unequivocally been shown to positively affect outcome in human patients experiencing cardiovascular shock. However, specific endpoints of resuscitation to target in critically ill patients remain controversial. Reliance on traditional endpoints of resuscitation (heart rate [HR], blood pressure [BP]) appears insufficient in detection of ongoing tissue hypoxia in shock states. A multitude of publications exist suggesting that indirect indices of global (lactate, base deficit, mixed/central venous oxygen saturation), regional (gastric intramucosal pH [pHi]) and cellular (transcutaneous oxygen) oxygenation are more successful in outcome prediction and in assessing adequacy of resuscitative efforts in this patient population. Veterinary‐based studies: While there are several large studies evaluating endpoints of resuscitation in experimental canine shock models, this author was unable to find similar research pertaining to small animal veterinary patients. The few articles in which blood lactate is evaluated for prognostic purposes in canine patients are included in this review. Data sources: Veterinary and human literature review. Conclusions: Optimization of early resuscitative efforts has proven to have a survival benefit in human shock patients, and major strides have been made in determining which endpoints of resuscitation to target in this patient population. Similar clinical trials designed to evaluate indices of ongoing global and regional tissue hypoxia in small animal veterinary shock patients are warranted.  相似文献

Objective: To review the human and veterinary literature on the current development and use of hemoglobin‐based oxygen‐carrying solutions. Human data synthesis: Hemoglobin‐based oxygen‐carrying (HBOC) solutions have been developed extensively over the last 3 decades. Early problems associated with pure hemoglobin and cytoskeleton residues have been resolved with chemical modification of the hemoglobin tetramer resulting in effective oxygen‐carrying molecules of either human or bovine origin. The limited availability of human red blood cells and concerns of disease transmission, the difficulty in mass production of genetically produced hemoglobin solutions (recombinant hemoglobin), and the wide availability of bovine blood have resulted in the development of bovine‐derived HBOC solutions. Research efforts have been directed toward determining the effects of HBOC solutions on tissue perfusion as the target uses of HBOC solutions in human medicine are the perioperative period, shock, and trauma fluid resuscitation. The most controversial issues regarding the cardiovascular effects of HBOC solutions surround increased vasoactivity. Some HBOC formulations have been removed from advanced clinical trials due to intense vasoactivity resulting in increased morbidity. There are currently 3 HBOC solutions in the latter stages of phase III clinical trials: Hemolink®, a Hemopure®, b and PolyHeme®. c The hemoglobin source of Hemopure® is bovine, and the hemoglobin source for Hemolink® and Polyheme® is human. Veterinary data synthesis: The only HBOC solution that has gained approval from the FDA is the veterinary product Oxyglobin®. d Oxyglobin® is 13 g/dL of ultrapurified, polymerized hemoglobin solution of bovine origin in a modified lactated Ringer's solution. There is a significant colloid effect and it also provides a plasma source of oxygen‐carrying capacity. The solution is stable at room temperature for 3 years; there is no special preparation required prior to use and no cross‐match is required prior to administration (contains no cell membranes). Veterinary publications on the use of Oxyglobin® include laboratory investigations in dogs, cats, and horses for use as a resuscitation fluid and for the treatment of anemia. Clinical use of Oxyglobin® in dogs, cats, birds, horses, and other mammalian species has been reported in several publications. Conclusion: The search for a safe, effective HBOC solution for use in human medicine is ongoing. Soon, there will be one or several products approved for use in the perioperative period and/or for the treatment of shock and trauma. The practice of veterinary emergency and critical care has been provided a unique opportunity to apply the use of an HBOC solution (Oxyglobin®) to various aspects of perfusion and oxygen‐carrying needs. Continued clinical experience and research is essential in understanding the use of HBOC solutions in veterinary medicine.  相似文献

Two young Akitas were examined because of manifestation of a juvenile-onset form of polyarthritis. A search of medical records at the New York State College of Veterinary Medicine found 6 more similarly affected Akitas. The clinical manifestations were marked by cyclic febrile illness and signs of profound joint-related pain. Two dogs had concurrent aseptic meningitis. The syndrome resembles juvenile rheumatoid arthritis in human beings, although it shares features with systemic lupus erythematosus. Pedigree analysis of affected Akitas supported a heritable component to the syndrome. Treatment with immunosuppressive drugs was effective in 2 dogs that achieved complete remission, and in 2 dogs that achieved only partial remission. Classification of this syndrome is difficult and may represent an "overlap" syndrome commonly described in human beings.  相似文献

Control of bovine viral diarrhea virus (BVDV) in cattle populations across most of the world has remained elusive in spite of advances in knowledge about this viral pathogen. A central feature of virus perseverance in cattle herds is the unique mechanism of persistent infection. Managing BVDV infection in herds involves controlling persistently infected carrier animals using a multidimensional approach of vaccination, biosecurity, and identification of BVDV reservoirs. A decade has passed since the original American College of Veterinary Internal Medicine consensus statement on BVDV. While much has remained the same with respect to clinical signs of disease, pathogenesis of infection including persistent infection, and diagnosis, scientific articles published since 2010 have led to a greater understanding of difficulties associated with control of BVDV. This consensus statement update on BVDV presents greater focus on topics currently relevant to the biology and control of this viral pathogen of cattle, including changes in virus subpopulations, infection in heterologous hosts, immunosuppression, and vaccination.  相似文献

Two non-invasive blood pressure (NIBP) devices (oscillometry and Doppler) were compared to invasive blood pressure using a Bland–Altman analysis, in anesthetized and conscious dogs. When considering the systolic arterial pressure only during general anesthesia, both NIBP devices slightly underestimated the systolic arterial blood pressure however the precision and the limits of agreement for the Doppler were of a greater magnitude. This indicates a worse clinical performance by the Doppler. The performance of both NIBP devices deteriorated as measured in conscious animals. In general, for the oscillometric device, determination of invasive diastolic and mean arterial pressures was better than the invasive systolic arterial pressure. Overall, the oscillometric device satisfied more of the criteria set by the American College of Veterinary Internal Medicine consensus statement. Based upon these results, the oscillometric device is more reliable than the Doppler in the determination of blood pressure in healthy medium to large breed dogs.  相似文献

Objective: To describe the technique of thromboelastography (TEG) and review the applications of this coagulation test in humans and small animals. Data sources: Data sources included scientific reviews and original research publications. Human data synthesis: TEG in humans has been used for documentation of hypercoagulable and hypocoagulable states and has been shown to be beneficial in patient management. Veterinary data synthesis: Clinical evaluation of TEG in veterinary medicine is limited; however, recent reports have documented evidence of hypercoagulability in dogs with parvovirus and protein‐losing nephropathy. Additionally, many of the research models may be relevant to veterinary patients. Conclusions: TEG provides information about coagulation that is not available through routine coagulation tests. The application of TEG monitoring to veterinary patients shows promise; however, prospective clinical studies are needed.  相似文献

One of the primary objectives of the Oncology‐Pathology Working Group (OPWG), a joint initiative of the Veterinary Cancer Society and the American College of Veterinary Pathologists, is for oncologists and pathologists to collaboratively generate consensus documents to standardize aspects of and provide guidelines for oncologic pathology. Consensus is established through critical review of peer‐reviewed literature relevant to a subgroup's particular focus. Subsequent acceptance and approval of the document by the OPWG membership at large establishes consensus. The intent of this publication is to help educate practitioners and pathologists on the value of diagnostics related to the KIT receptor tyrosine kinase for canine cutaneous mast cell tumours and to provide a guide for the use of these tests in veterinary medicine. This document represents the opinions of the OPWG and the authors and does not constitute a formal endorsement by the American College of Veterinary Pathologists or the Veterinary Cancer Society.  相似文献

Concerns about the completeness and accuracy of reporting of randomized clinical trials (RCTs) and the impact of poor reporting on decision making have been documented in the medical field over the past several decades. Experience from RCTs in human medicine would suggest that failure to report critical trial features can be associated with biased estimated effect measures, and there is evidence to suggest that similar biases occur in RCTs conducted in livestock populations. In response to these concerns, standardized guidelines for reporting RCTs were developed and implemented in human medicine. The Consolidated Standards of Reporting Trials (CONSORT) statement was first published in 1996, with a revised edition published in 2001. The CONSORT statement consists of a 22‐item checklist for reporting a RCT and a flow diagram to follow the number of participants at each stage of a trial. An explanation and elaboration document not only defines and discusses the importance of each of the items, but also provides examples of how this information could be supplied in a publication. Differences between human and livestock populations necessitate modifications to the CONSORT statement to maximize its usefulness for RCTs involving livestock. These have been addressed in an extension of the CONSORT statement titled the REFLECT statement: Methods and processes of creating reporting guidelines for randomized control trials for livestock and food safety. The modifications made for livestock trials specifically addressed the common use of group housing and group allocation to intervention in livestock studies; the use of deliberate challenge models in some trials and the common use of non‐clinical outcomes, such as contamination with a foodborne pathogen. In addition, the REFLECT statement for RCTs in livestock populations proposed specific terms or further clarified terms as they pertained to livestock studies.  相似文献
