Feline aortic thromboemboli and the potential utility of thrombolytic therapy with tissue plasminogen activator 总被引：2，自引：0，他引：2
P D Pion 《Veterinary Clinics of North America: Small Animal Practice》1988,18(1):79-86
Feline aortic thromboembolism is a common and devastating clinical condition for which there is presently no effective therapy. Thrombolytic therapy with tissue plasminogen activator represents a promising, relatively noninvasive method for resolution of the clinical syndrome. In clinical trials in man, tissue plasminogen activator is proving to have advantages over previously available thrombolytic agents. Previously available thrombolytic agents require intensive monitoring and commonly cause complications that entail large monetary and manpower costs to monitor and control. Being specific for thrombus-associated plasminogen, t-PA enables more safe and effective thrombolysis without the hazards previously associated with thrombolytic therapy. In cats with aortic thromboemboli, early clinical trials are promising with regard to acute thrombolytic efficacy but raise questions concerning the risks and benefits of therapy and will require more controlled studies. It is estimated that t-PA therapy for a cat with aortic thromboemboli will cost approximately +500 to +1500, including hospitalization and drugs. This compares favorably with what most veterinary clients are willing to spend for quality veterinary care. However, before we can look upon t-PA therapy as a useful therapeutic advance, we must consider the etiopathogenesis and probability of rethrombosis. The results of controlled studies have not been published, but it is generally considered that there is a high probability of recurrence in cats. Fifty per cent of cats treated with t-PA have rethrombosed despite aspirin therapy at the recommended dose of 25 mg per kg every third day. Finding a cure for feline myocardial diseases (cardiomyopathies) and/or an effective method for safely anticoagulating cats at risk would help justify the monetary and manpower costs associated with thrombolytic therapy.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

OBJECTIVE: To determine if clopidogrel enhanced the thrombolytic rate of tissue-plasminogen activator (t-PA) on an in vitro feline whole blood thrombosis model. ANIMALS: 9 purpose-bred cats. PROCEDURE: Blood obtained from cats before (baseline) and after treatment with clopidogrel (75 mg, p.o., q 24 h for 3 days) was anticoagulated with sodium citrate (9:1 volume-to-volume ratio) to which 1 microCi of I125-fibrinogen was added. Thrombi were formed by the addition of calcium chloride and bovine thrombin. Thrombi were placed into autologous plasma to which 0.1 mg of t-PA was added. Plasma samples were collected at different time points to determine the amount of released I125-fibrin split products. Thrombolytic rates were calculated by determining the time to 25%, 50%, and 75% thrombolysis (t25, t50, and t75, respectively). Confidence intervals for t25, t50, and t75 at baseline were compared with those after treatment. RESULTS: There were no significant differences in thrombolytic rates between values obtained at baseline and after clopidogrel treatment (t25, 18.0 vs 18.5 minutes; t50, 63.3 vs 65.6 minutes; and t75, 163.0 vs 170.1 minutes, respectively). CONCLUSIONS AND CLINICAL RELEVANCE: Clopidogrel did not have an effect on the rate of thrombolysis of feline whole blood thrombi induced by t-PA in this in vitro model. 相似文献

Introduction: Greater than 50% of dogs with thyroid tumors present with surgically unresectable disease for which external beam radiotherapy has been reported to prolong survival. The success of 131 I for control of thyroid tumors in cats and in humans suggests such therapy may also play a role in the management of canine thyroid cancer.
Methods: Thirty‐nine dogs with WHO stage II/III (invasive or ectopic; n = 32) or IV (metastatic; n = 7) thyroid tumors were treated with131 I alone. Changes in thyroid function, 99M Tc‐pertechnetate (99M Tc) scintigraphic changes, and tumor response were recorded. Dogs with ventral cervical tumors were evaluated for feasibility of surgical resection following 131 I.
Results: Median overall survival was 839 days and 366 days for dogs with stage II/III and stage IV tumors, respectively. Thyroid hormone status, site and surgical resection were not associated with outcome in dogs with stage II/III tumors. Three dogs developed severe bone marrow suppression.
Conclusions: These findings suggest131 I should be investigated more thoroughly in dogs with thyroid tumors not considered surgical candidates to more clearly characterize the indications for therapy and followup recommendations. 131 I dosimetry in dogs with thyroid tumors remains problematic. Administration of 131 I is currently based on empiric recommendations and, in general, the treatment is well tolerated although additional studies are indicated to optimize response and minimize toxicity. 相似文献

A 4-year-old, castrated male Maltese developed cranial vena caval thrombosis and chylothorax following central venous catheterization for treatment of postoperative sepsis. Vena caval thrombolysis was attempted using recombinant human tissue-plasminogen activator (t-PA). Thrombolytic therapy led to an acute reduction in the size of the caval thrombus and was followed by prompt resolution of the chylothorax. Hemorrhage at the entry sites of a jugular catheter and esophagostomy tube placed at the time of treatment was a dose-limiting complication of t-PA therapy in this dog. 相似文献

Background: Chronic kidney failure is frequently seen in middle-aged and elderly cats. 51 Chromium-ethylene diaminic tetraacetic acid (51 Cr-EDTA) clearance and single blood sample (SBS) method are used in several species to estimate the glomerular filtration rate (GFR).
Hypothesis: The hypothesis of this study was that51 Cr-EDTA clearance could be determined using an SBS method in normal and hyperthyroid cats.
Animals: Forty-six cats were included in this study, with an average age of 9.5 years. Of these cats, 27 had hyperthyroidism; 19 were healthy.
Methods: After IV injection of51 Cr-EDTA (average dose: 4.25 MBq), 7 blood samples were obtained between 5 and 240 minutes. Reference clearance was calculated in mL/min and mL/min/kg body weight, using a 2-compartment model. Optimal time for clearance measurement with SBS was then determined by systematically comparing each individual plasma concentration to the reference multisample clearance.
Results: The average reference plasma clearance of51 Cr-EDTA for all cats was 14.9 mL/min (3.7 mL/min/kg). The clearance in hyperthyroid cats averaged 16.4 mL/min (4.3 mL/min/kg) and in normal cats averaged 10.3 mL/min (2.4 mL/min/kg).
The optimal time for the SBS was 48 minutes after injection of tracer51 Cr-EDTA ( R 2 = 0.9414), giving the following converting equation: clearance = (0.0066 × DV48 minutes ) – 0.9277 (in mL/min).
Conclusions and Clinical Importance: In this study, the single sample51 Cr-EDTA clearance method was used to estimate the global GFR in cats. The method identified differences in clearance between normal and hyperthyroid cats. The optimal time for an SBS was 48 minutes. 相似文献

Objective To evaluate and to validate the accuracy of the Perkins® handheld applanation tonometer in the measurement of IOP in dogs and cats.
Animals Twenty eyes from 10 dogs and 10 cats immediately after sacrifice were used for the postmortem study and 20 eyes from 10 clinically normal and anesthetized dogs and cats were used for the in vivo study. Both eyes of 20 conscious dogs and cats were also evaluated.
Procedure Readings of IOP postmortem and in vivo were taken using manometry (measured with a mercury column manometer) and tonometry (measured with a Perkins® handheld applanation tonometer). The IOP measurement with Perkins® tonometer in anesthetized and conscious dogs and cats was accomplished by instillation of proxymetacaine 0.5% and of 1% fluorescein eye drops.
Results The correlation coefficient ( r2 ) between the manometry and the Perkins® tonometer were 0.982 (dogs) and 0.988 (cats), and the corresponding linear regression equation were y = 0.0893 x + 0.1105 (dogs) and y = 0.0899 x + 0.1145 (cats) in the postmortem study. The mean IOP readings with the Perkins® tonometer after calibration curve correction were 14.9 ± 1.6 mmHg (range 12.2–17.2 mmHg) in conscious dogs, and were 15.1 ± 1.7 mmHg (range 12.1–18.7 mmHg) in conscious cats.
Conclusion There was an excellent correlation between the IOP values obtained from direct ocular manometry and the Perkins® tonometer in dogs and cats. The Perkins® handheld tonometer could be in the future a new alternative for the diagnosis of glaucoma in veterinary ophthalmology. 相似文献

Background: Retinol-binding protein (RBP) is suggested as a clinically useful marker of renal function in cats.
Hypothesis: Serum and urinary RBP concentrations in hyperthyroid (HT) cats differ from those in healthy (H) cats; radioiodine (131 I) treatment influences serum and urinary RBP concentrations in HT cats.
Animals: Ten HT and 8 H cats.
Methods: RBP concentration was evaluated in feline serum and urine samples from a prospective study.
Results: There was a significant ( P = .003) difference in the urinary RBP/creatinine (uRBP/c) ratios of H (−) and untreated HT (1.4 ± 1.5 × 10−2 μg/mg) cats. Serum total thyroxine concentration (1.8 ± 1.9 μg/dL, 24 weeks) and uRBP/c (0.6 ± 1.0 × 10−2 μg/mg, 24 weeks) decreased significantly ( P < .001) in HT cats at all time points after treatment with 131 I, and these variables were significantly correlated with one another ( r = 0.42, P = .007). Serum RBP concentrations from HT cats (199 ± 86 μg/L) did not differ significantly ( P = .98) from those of H cats (174 ± 60) and did not change after treatment with 131 I (182 ± 124 μg/L, P = .80).
Conclusion and Clinical Importance: The presence of urinary RBP in HT cats is a potential marker of tubular dysfunction that is correlated to thyroid status, although it is independent of circulating RBP concentrations. The decreased uRBP/c combined with the absence of changes in serum RBP after treatment suggests that the suspected tubular dysfunction was partly reversible with treatment of131 I. 相似文献

Although pain management is an emerging and popular topic in veterinary medicine, use of analgesics in cats has received little attention relative to their canine counterparts. Some of the difficulty lies in assessment of whether or not a cat is in pain. Simple observation of a cat in a cage relies upon overt expression of pain, and is often inaccurate. Pain scales have been developed that allow a semiquantitative evaluation of the degree of pain an animal may be experiencing. However, treating pain based upon observation of the painful state is less effective than anticipating and preemptively treating pain. This article reviews specific methods for preemptively treating and alleviating pain in the cat. The traditional approach to pain management involves drug administration. Specific categories of agents used in cats include opioids, nonsteroidal anti-inflammatories, or alpha-2 agonists. Other modalities of pain management, which are also reviewed, include use of local anesthetic drugs for local and regional analgesia, as well as acupuncture. 相似文献

Objective: To compare the effect of a balanced isotonic crystalloid solution with that of 0.9% sodium chloride on the acid–base and electrolyte status of cats with urethral obstruction.
Design: Randomized prospective clinical trial.
Setting: Academic veterinary emergency room.
Animals: Sixty-eight cats with naturally occurring urethral obstruction.
Interventions: Cats were randomized to receive either a balanced isotonic crystalloid solution (Normosol-R, n =39) or 0.9% sodium chloride ( n =29) for fluid therapy. Baseline venous blood gas and blood electrolyte values were obtained at the time of admission and at intervals during the course of therapy.
Measurements and main results: Baseline values were similar between groups. Cats receiving Normosol-R had a significantly higher blood pH at 12 hours, a significantly greater increase in blood pH from baseline at 6 and 12 hours, as well as a significantly higher blood bicarbonate concentration at 12 hours and a significantly greater increase in blood bicarbonate from baseline at 6 and 12 hours. Conversely, the increase in blood chloride from baseline was significantly higher at 2, 6, and 12 hours in cats receiving 0.9% sodium chloride. There were no significant differences in the rate of decline of blood potassium from baseline between groups. Subgroup analysis of hyperkalemic cats (K+ >6.0 mmol/L) and acidemic cats (pH<7.3) yielded similar findings.
Conclusions: While both crystalloid solutions appear safe and effective for fluid therapy in cats with urethral obstruction, the use of a balanced electrolyte solution may allow more rapid correction of blood acid–base status within the first 12 hours of fluid therapy. The use of a potassium-containing balanced electrolyte solution does not appear to affect the rate of normalization of blood potassium in treated cats with urethral obstruction. 相似文献

Objectives – To review the principles and available technology for pretransfusion testing in veterinary medicine and discuss the indications and importance of test performance before RBC transfusion.
Data Sources – Current human and veterinary medical literature: original research articles and scientific reviews.
Summary – Indications for RBC transfusion in veterinary medicine include severe anemia or tissue hypoxia resulting from blood loss, decreased erythrocyte production, and hemolyzing conditions such as immune-mediated anemia and neonatal isoerythrolysis. Proper blood sample collection, handling, and identification are imperative for high-quality pretransfusion testing. Point-of-care blood typing methods including both typing cards and rapid gel agglutination are readily available for some species. Following blood typing, crossmatching is performed on one or more donor units of appropriate blood type. As an alternative to technically demanding tube crossmatching methods, a point-of-care gel agglutination method has recently become available for use in dogs and cats. Crossmatching reduces the risk of hemolytic transfusion reactions but does not completely eliminate the risk of other types of transfusion reactions in veterinary patients, and for this reason, all transfusion reactions should be appropriately documented and investigated.
Conclusion – The administration of blood products is a resource-intensive function of veterinary medicine and optimizing patient safety in transfusion medicine is multifaceted. Adverse reactions can be life threatening. Appropriate donor screening and collection combined with pretransfusion testing decreases the occurrence of incompatible transfusion reactions. 相似文献

Replicating oncolytic viruses (OVs) are appealing, new, FDA‐approved, therapeutic options for humans with head and neck cancers and melanomas. These treatments are not yet available for veterinary patients, but recent clinical trials have shown several OVs to be safe in dogs and cats. Specific viruses being used to treat sarcomas in dogs include modified canine adenovirus 2, myxoma virus, vesicular stomatitis virus and reovirus. In cats with vaccine‐associated sarcomas, poxviruses have been injected postoperatively and a reduced rate of tumour recurrence was documented. To date, the response rates of canine and feline patients to OV therapy have been variable (as they are in people). Optimal methods of OV administration and dosing schedules continue to be evaluated. One way to improve outcomes of OV therapy in veterinary patients may be to use OVs in combination with other immunomodulatory therapies. This review discusses the potential utility of concurrent therapy with an OV and an inhibitor of the type I interferon pathway. 相似文献

Positron emission tomography (PET) has found widespread application for staging and monitoring neoplastic diseases in humans. PET is becoming more available in veterinary medicine, therefore biodistribution of 2-deoxy-2-[18 F]fluoro- d -glucose (18 FDG) in normal dogs is needed for lesion interpretation in disease states. A large field-of-view (FOV) PET scanner with a 70 cm bore diameter and a 53-cm FOV was used in this study to acquire dynamic 18 FDG uptake data from parenchymal organs in seven normal dogs. A 2-h, dynamic list-mode acquisition was initiated simultaneously with intravenous 18 FDG injection. Regions of interest (ROIs) were manually drawn over liver, spleen, left and right renal cortices, left ventricular free wall, and thymus. Standardized uptake values (SUVs) of these organs were calculated for 24 5-min frames over the 2-h acquisition. This SUV data from parenchymal organs of normal dogs compares favorably with those of normal humans and will be used in ongoing canine studies using PET to evaluate various diseases. 相似文献

Veterinary behavioral medicine remains an under-supported, under-appreciated, and under-taught specialty within veterinary medicine. Neuropsychopharmacology is the aspect that has provided the field with the most scientific legitimacy, but is also one of the most hotly debated. Paradigms for use of pharmacologic intervention include firstly ruling out any underlying medical cause. If a behavioral diagnosis can be made, treatment with psychotropic medication may be considered, although their use is most effective as part of an integrated treatment program that includes behavior modification. Used without an understanding of the mechanism of action, pharmacologic intervention may only blunt or mask behavior without altering processes or environments that produced the behavior. This paper reviews specific drugs, mechanism of action of those drugs, and relevant uses are reviewed for cats. Future advances in treatment in veterinary behavioral medicine will be pharmacological and neurophysiological. As the field of veterinary behavioral medicine expands, its paradigm will enlarge to include routine combination therapy and the implementation of neuropharmacological intervention as a diagnostic tool. 相似文献

Over representation of Burmese cats with diabetes mellitus 总被引：2，自引：0，他引：2
Objective To determine if Burmese cats in Queensland have an increased risk of diabetes mellitus.
Design A retrospective study of diabetic and nondiabetic cats that had blood submitted to a veterinary clinical laboratory over a 22 month study period.
Sample population 4402 cats
Procedure Cats were considered diabetic if blood glucose concentration was > 11 mmol/L and fructosamine was > 406 μmol/L or hydroxybutyrate was >1 mmol/L. Cats were grouped into Burmese and non-Burmese. Adjusted odds ratios of diabetes were calculated for breed, gender and age group amongst cats with blood glucose > 11 mmol/L.
Results Burmese cats comprised 20% of 45 diabetic cats of known breed, which was higher (P < 0.001) than among the normoglycemic reference population of 2203 cats (7% Burmese). There were more females among the diabetic Burmese (62%), but this did not differ (P > 0.05) from the Burmese reference population (45% females). In contrast, males seemed to predominate among diabetic non-Burmese (63%), although this also did not differ (P > 0.05) from the reference population (55%) or from diabetic Burmese (38% males). The majority (90%) of diabetic cats were older than 6 years, irrespective of breed (median age 12 years, interquartile range 10 to 13 years). This was higher (χ2 = 8.13, P < 0.005) than among the normoglycaemic reference population, where 69% were older than 6 years.
Conclusions Burmese cats were significantly over represented among cats with diabetes mellitus. Irrespective of breed, the risk of diabetes in the study population increased with age. 相似文献

Recombinant human thyrotropin (rhTSH) was developed after bovine thyrotropin (bTSH) was no longer commercially available. It was approved by the Food and Drug Administration (FDA) and the European Medicines Agency (EMEA) as an aid to diagnostic follow-up of differentiated thyroid carcinoma in humans and for thyroid remnant ablation with radioiodine. In addition, rhTSH is used in human medicine to evaluate thyroid reserve capacity and to enhance radioiodine uptake in patients with metastatic thyroid cancer and multinodular goiter. Likewise, rhTSH has been used in veterinary medicine over the last decade. The most important veterinary use of rhTSH is thyroidal functional reserve testing for the diagnosis of canine hypothyroidism. Recent pilot studies performed at Ghent University in Belgium have investigated the use of rhTSH to optimize radioiodine treatment of canine thyroid carcinoma and feline hyperthyroidism. Radioiodine treatment optimization may allow a decreased therapeutic dosage of radioiodine and thus may improve radioprotection. This review outlines the current uses of rhTSH in human and veterinary medicine, emphasizing research performed in dogs and cats, as well as potential future applications. 相似文献

Over the past several decades, recognition of acute respiratory failure as the cause of death in patients suffering from various clinical conditions has prompted aggressiv investigation into the area of respiratory physiology and supportive respiratory care. With the evolution of emergency medicine and critical care services in both human and veterinary medicine, many patients previously considered unsalvageable due to the severity of their underlying disease are now being resuscitated and successfully supported, creating a new population of critically ill patients. Where only a decade ago these patients would have succumbed to their underlying disease, they now survive long enough to manifest the complications of shock and tissue injury in the form of acute respiratory failure. Investigation into the pathophysiology and treatment of this acute respiratory distress syndrom (ARDS) has facilitated increased clinical application of respiratory theerapy and machanical ventilation.1 The purpose of this paper is to provide a basic review of respiratory mechanics and the pathophysiology of hypoxemia as they relate to airway pressure therapy in veterinary patients and to review the use of airway pressure therapy in veterinary patients This paper is divided into two parts; part I reviews respiratory mechanics and hypoxemia as they apply to respiratory therapy, while part II deals specifically with airway pressure therapy andits use in clinical cases. 相似文献

Continuous low-dose-rate irradiation of animal tumors has become feasible through the implantation of iridium-192 by an afterloading technique. 192 Ir is an ideal radioisotope for interstitial brachytherapy in veterinary medicine because of its 74.2-day half-life, medium-energy gamma radiation (0.35 MeV), moderate shielding requirements, low cost, and adaptability to most tumor configurations. The afterloading technique can easily be applied to veterinary patients. The effectiveness of interstitial brachytherapy may be enhanced by combination with surgery and/or hyperthermia. Computer-assisted dose calculations make afterloaded 192 Ir implantation an accurate, precise method of interstitial brachytherapy. 相似文献
