Background: Although prednisone and metronidazole are commonly used to treat canine inflammatory bowel disease (IBD), no randomized‐controlled trials have been performed. Hypothesis: Combination drug therapy with prednisone and metronidazole will be more effective than prednisone alone for treatment of canine IBD. Reduction in disease severity will be accompanied by decreased canine IBD activity index (CIBDAI) scores and serum C‐reactive protein (CRP) concentrations. Animals: Fifty‐four pet dogs diagnosed with IBD of varying severity. Methods: Dogs were randomized to receive oral prednisone (1 mg/kg; n = 25) or prednisone and metronidazole (10 mg/kg; n = 29) twice daily for 21 days. Clinical (CIBDAI) scores and serum CRP were determined at diagnosis and after 21 days of drug therapy. The primary efficacy measure was remission at 21 days, defined as a 75% or greater reduction in baseline CIBDAI score. Results: Differences between treatments in the rate of remission (both exceeding 80%) or the magnitude of its change over time were not observed. CRP concentrations in prednisone‐treated dogs were increased because of many dogs having active disease. Both treatments reduced CRP in comparison with pretreatment concentrations. An interaction between CIBDAI and CRP was identified in 42 of 54 dogs (78%), whereas 8 of 54 dogs (15%) showed disagreement between these indices. Conclusions and Clinical Importance: Prednisone is as effective as combined treatment with prednisone and metronidazole for induction therapy of canine IBD. CRP may be normal or increased in dogs with IBD and may be useful in assessing the response of individual dogs to treatment along with changes in the CIBDAI. 相似文献

Cryptococcus neoformans meningoencephalitis was diagnosed as the cause of stupor and generalized seizures in a 2-year-old Cocker Spaniel. Unilateral granulomatous chorioretinitis was observed ophthalmoscopically, and isolation of C neoformans from CSF confirmed the antemortem diagnosis. The dog was euthanatized and necropsied. Multifocal lesions were seen throughout the lungs, nasal turbinates, cerebral cortex, and the optic nerve of each eye. Microscopically, the multifocal lesions were granulomas consisting of lymphocytes, macrophages, plasma cells, and cryptococcal organisms. Infection may have originated in the nasal passages and extended directly through the ethmoid plate into the meninges of the CNS and optic nerves. Although the prognosis is poor in dogs with CNS involvement, various chemotherapeutic agents are available for use by clinicians. 相似文献

Paraesophageal hiatal hernia and pyloric obstruction in a dog 总被引:1,自引:0,他引:1

Paraesophageal hiatal herniation and pyloric obstruction were diagnosed in a pup with a history of vomiting. Findings of contrast radiography included esophageal reflux, delayed gastric emptying time, and paraesophageal herniation. Exploratory celiotomy revealed increased firmness of the pylorus and a primary defect in the esophageal hiatus, which allowed gastric herniation. Nissen fundoplication was performed following reconstruction of the esophageal hiatus, and pyloroplasty was performed to relieve the gastric outlet obstruction. Pyloric biopsy findings were consistent with a diagnosis of chronic gastritis. Recovery from surgery was initially unremarkable; however, the dog died suddenly 3 weeks after surgery. Necropsy revealed a large diaphragmatic hernia adjacent to the esophageal hiatus; the hernia had resulted in incarceration of the abdominal organs. The hiatal hernia reconstruction remained intact and was not the cause of the diaphragmatic disruption. 相似文献

Unilateral perinephric pseudocyst of undetermined origin was diagnosed in a 131/2 year old dog with a history of recurrent urinary tract infections. A presumptive diagnosis of pseudocyst was based on radiographic and sonographic findings. In survey radiographs, asymmetrical unilateral renomegaly was seen. The mass was anechoic. There was absence of opacification of the mass during excretory urography. A celiotomy was performed for removal of the perinephric mass, and histologic review of this structure confirmed it to be a pseudocyst. Perinephric accumulation of fluid is a rare condition in domestic animals. Seven examples of perinephric pseudocysts have been previously reported in the cat. Predominant clinical findings include progressive abdominal distension and nonspecific signs of renal disease. The presence of unilateral or bilateral renomegaly is a characteristic radiographic feature. This clinical report describes the first case of perinephric pseudocyst diagnosed in the dog. 相似文献

A 10-year-old female Labrador Retriever with intermittent lameness, lethargy, pancytopenia, hyper-calcemia, and severe hyperproteinemia was diagnosed as having plasma cell myeloma. Diagnosis was confirmed by finding a monoclonal gammopathy, extensive plasmacytic bone marrow infiltration, and radiographic evidence of skeletal disease. Survey radiography revealed atypical lytic proliferative osseous lesions involving the spinous process of the third thoracic vertebrae, left third rib, and both left and right fifth ribs. Nutritional support and specific chemotherapy with Melphalan have resulted in long-term clinical remission. This report describes the radiographic and clinicopathologic features of plasma cell myeloma in the dog. A discussion of the previously reported radiographic features of this neoplasm is also included. 相似文献

Clinical indices, consisting of gastrointestinal signs and laboratory parameters, are widely used for assessing disease activity in human inflammatory bowel disease (IBD). The development of a standardized scoring index for use in dogs with IBD would be useful in the management of clinical cases, both at diagnosis and in response to medical therapy. This review provides a synopsis of current strategies used to assess IBD activity in humans and companion animals. The clinical application of a simple scoring index (e.g., canine IBD activity index [CIBDAI]) for measurement of canine IBD activity is also reviewed. 相似文献

Flow cytometric analysis of the lymphocyte population of the gut could provide useful information on the immune cells present in the gut that would not be easily obtained in tissue sections. However, little is known of the normal lymphocyte population in the canine gut as determined by flow cytometry, which allows for simultaneous staining of multiple cell surface antigens and identification of specific lymphocytic subsets. Therefore, intraepithelial lymphocytes were obtained from biopsies of the healthy canine proximal small intestine and colon taken with an endoscope, and flow cytometric analysis was used to characterize the lymphocyte subsets present. Endoscopic biopsy of the intestine is a minimally invasive technique commonly used for diagnostic purposes. Although CD3+ lymphocytes were the most abundant subset in both colon and small intestine, CD3+/CD8- lymphocytes predominated in the proximal small intestine, whereas CD3+/CD8+ lymphocytes did in the colon. Canine CD8+ intraepithelial lymphocytes were predominantly CD8alphabeta+ in both small intestine and colon. CD4+ intraepithelial lymphocytes were always much less numerous than CD8+ intraepithelial lymphocytes. As in man, a majority of intraepithelial lymphocytes expressed the T-cell receptor, TCRalphabeta, but TCRgammadelta was expressed by a third of intraepithelial T-cells in the proximal small intestine, and approximately 15% of those in the colon. Very few CD21+ lymphocytes were detected in samples of healthy canine colon and small intestinal intraepithelial cells. We have showed that canine intraepithelial lymphocytes are regionally specialized, and that those from the small intestine are unique in comparison to those of other species such as man and rodents due to the large numbers of CD3+/CD8- intraepithelial lymphocytes. This study provides a baseline for comparison with intraepithelial lymphocytes obtained from canine patients with intestinal disease. 相似文献
