Twenty-two dogs and cats with symptomatic renal or hepatic cysts that had undergone ultrasound-assisted drainage and alcoholization were retrospectively evaluated. Common presenting complaints were anorexia, reluctance to move, and vomiting. Abdominal pain was observed in all cases. Systemic hypertension was identified in four dogs and four cats with renal cysts. Cyst drainage and alcoholization were achieved without complications in 19 animals, and all clinical signs resolved after the procedure. In three cases, transient bleeding was observed during alcoholization, and the procedure was interrupted. Blood pressure normalized in the four dogs with renal cysts, but it remained elevated in the four cats. 相似文献

Thirty dogs naturally infected with Leishmania infantum were studied in order to determine the effects of treatment on haemostatic function. The animals were divided randomly into two treatment groups: Group 1 received meglumine antimoniate and allopurinol; Group 2 dogs were given the same treatment plus prednisone. Ten healthy animals were used as untreated controls. Clinical examination and determination of platelet aggregation, coagulation factors and biochemical parameters were undertaken before treatment and after 15, 30 and 60 days. A significant improvement in platelet aggregation was detected after 60 days in Group 1, but only after 15 days in Group 2. In both treated groups, platelet aggregation was lower than in the control group at the end of the study. The results suggest that prednisone may be a useful tool in the treatment of haemostatic disorders during canine leishmaniosis. The potential benefits and risks due to the use of corticosteroids in the treatment of leishmaniosis are discussed. 相似文献

Aiming to evaluate the efficacy of the treatment of canine visceral leishmaniasis, to verify the occurrence of a possible disease relapse, and to search for the presence of the parasites after the end of the treatment, seven dogs naturally infected by Leishmania (Leishmania) chagasi were used. The dogs were subjected to a treatment with 75 mg/kg meglumine antimoniate subcutaneously every 12 h for 21 days, and followed-up for a period of 6 months. During the whole experimental period the animals wore deltamethrin collars and were kept in a screened kennel to avoid reinfection. Lymph node and bone marrow aspiration biopsy was carried out to search for the parasite at seven moments: before the treatment, 30, 60, 90, 120, 150 and 180 days after the start of the treatment. After the end of the experiment all dogs were humanely euthanized. Then, spleen and liver "imprints" and in vitro cultures were carried out to search for amastigote forms of the parasite. During the treatment all animals presented remission of symptoms. However, two dogs were observed to present new symptoms in the course of the experiment. At the end of the experiment, the presence of amastigote forms of the parasite was evidenced in five of the seven dogs. This enabled us to conclude that the treatment promoted clinical cure but did not eliminate the parasites completely. 相似文献

Canine parvoviral enteritis continues to cause significant morbidity and mortality in dogs worldwide, and efficacious antiviral therapies are lacking. The present trial was aimed at evaluating the therapeutic efficacy of a recombinant feline interferon (type omega) preparation in the treatment of parvoviral enteritis in dogs. A double-blind, placebo-controlled challenge trial was performed in beagle pups (8-9 weeks); clinical signs, body weight, hematologic parameters, and mortality were monitored for a period of 14 days after challenge. Fourteen animals were inoculated with virulent canine parvovirus; 10 animals that developed clinical signs thereby meeting the inclusion criteria were admitted to the treatment phase in two randomly selected groups (placebo and IFN) of equal size. The IFN group received daily intravenous injections of rFeIFN-omega (2.5 MU/kg) for three consecutive days. The placebo group received daily injections of saline without IFN. Both groups of animals received individual supportive treatment consisting of adjusted diet and electrolyte solution.All five dogs in the placebo group developed fulminating enteritis with typical clinical signs and died within 10 days post-inoculation (or 6 days post-treatment). In the IFN-treated group, one animal died on day 2 after the treatment was started, whereas the other four dogs survived the challenge and gradually recovered. Our data confirm that the rFeIFN-omega can exert a significant therapeutic effect on dogs with parvoviral enteritis by improving clinical signs and reducing mortality. 相似文献

A retrospective study was undertaken on 56 dogs treated for nasal tumours by megavoltage radiotherapy with a hypofractionated schedule consisting of four doses of 9 Gy given at intervals of seven days. The dogs were followed until they died or were euthanased. The clinical signs had improved in 53 of the 56 dogs by the end of the treatment schedule. Mild acute radiation side effects were observed in the majority of the dogs but late radiation side effects were rare. Kaplan-Meier survival analysis revealed a median survival time after the final dose of radiation of 212 days. The one- and two-year survival rates were 45 per cent and 15 per cent. Fifty of the dogs were euthanased because the initial clinical signs recurred. 相似文献

Objective To determine whether induction of pancreatic necrosis and islet proliferation by d,l‐ethionine has potential for treating dogs with b ‐cell insufficiency. Design Eighteen mixed breed dogs of both sexes were given d,l‐ethionine at 100 mg/kg three times weekly for 2 weeks; 6 dogs were euthanased at 2, 14 and 28 d after the last dose. Methods Clinical signs during administration and recovery were assessed. Routine biochemical analyses were performed before each ethionine dose and then once weekly. Faecal samples were examined weekly for malassimilated nutrients and blood. Blood coagulation screening tests (OSPT and APTT) were determined on four dogs after ethionine administration. Intravenous glucose tolerance tests were conducted before the first and after the last ethionine dose and then fortnightly. All dogs were necropsied and pancreas, liver, kidney and jejunum were examined microscopically. Results During ethionine administration all animals displayed vomiting, inappetence, diarrhoea (often with blood), weight loss and depression. Three dogs were euthanased prematurely due to severe illness, but those allowed to recover were eating and brighter 7 d after cessation of ethio‐nine administration. Serum concentrations of TLI, amylase and lipase increased initially, then decreased, during administration but returned to normal during recovery. Concentrations of ALT, ALP, unconjugated and conjugated bilirubin increased during administration then decreased slowly. Histological examination revealed hepatic lipidosis and necrosis, but no renal or jejunal lesions. In most dogs, faecal examination demonstrated increased undigested starch and muscle, as well as increased digested and undigested fat, during ethio‐nine administration or early during the recovery period, suggesting transient malassimilation. APTT was unchanged but OSPT was prolonged in all dogs. There was no impairment of insulin secretion or glucose intolerance and C‐peptide concentrations were unaffected. Immediately after ethionine administration there was delayed insulin degradation and by day 43 there was evidence of increased insulin sensitivity. Conclusion d,l‐ethionine administration in dogs appeared not to interfere with insulin secretion, but caused clinical signs and laboratory changes indicative of pancreatic exocrine necrosis, severe hepatobiliary disease and transient malas‐similation. Pancreatic and hepatic dysfunction was severe but clinical recovery occurred after ethionine administration ceased. The severe side‐effects observed with d,l‐ethionine should preclude its potential use for treating diabetes mellitus in dogs. 相似文献

Twenty-seven dogs infected naturally with Leishmania infantum were used in a randomised controlled trial to compare the clinical and parasitological efficacy of an oral treatment with a combination of metronidazole and spiramycin (13 dogs) with the efficacy of conventional treatment with meglumine antimonate and allopurinol (14 dogs) as controls. In the test group one dog had to be withdrawn from the treatment because it developed pemphigus foliaceus; 10 of the dogs were clinically responsive but none was cured parasitologically. In the control group four dogs were withdrawn from the treatment because of side effects; eight of the dogs were clinically responsive but none was cured parasitologically. The control group showed signs of improvement after an average of 30 days, whereas the test group did not show signs of improvement until after an average of 45 days. 相似文献

The aim of this study was to investigate whether treatment against canine leishmaniasis reduced the presence of Leishmania in the healthy skin of dogs, affecting the capacity of parasite transmission. A total of 37 dogs from an endemic region of leishmaniasis were studied. Thirteen symptomatic animals revealed parasites in the bone marrow and eight had also in the skin. Five of the 22 dogs that had been treated with meglumine antimoniate alone, meglumine antimoniate or trifluralin followed by allopurinol or just with allopurinol had the parasite in bone marrow but none showed Leishmania in the skin. One dog that was treated only with aminosidine was polisymptomatic and had parasites in bone marrow and skin. The different treatments used in this study did not completely eliminate the parasite allowing relapses to occur when the treatment is discontinued, but the use of meglumine antimoniate or allopurinol, alone or combined may improve dogs clinical condition and reduce or eliminate the parasite from the skin decreasing the probability of Leishmania transmission. 相似文献

Congenital portosystemic shunts are a common cause of hepatic encephalopathy and are typically first identified when dogs are <2 years of age. This case series describes five dogs with congenital portosystemic shunts; the dogs were presented for severe encephalopathic signs during middle or old age. Three dogs had portoazygos shunts, and four dogs had multifocal and lateralizing neurological abnormalities, including severe gait abnormalities and vestibular signs. All five dogs responded to medical or surgical treatment, demonstrating that older animals can respond to treatment even after exhibiting severe neurological signs. 相似文献

This study included a total of 14 dogs with spontaneous esophageal spirocercosis. Historical and clinical evidence of esophageal dysphagia, detection of parasitic ova in fecal samples and endoscopic documentation of esophageal nodules were the inclusion criteria. The animals were randomly assigned into two groups: group A (n = 6 ) dogs received two intranodular injections of absolute ethanol (96%) via a through-the-endoscope injector, at weekly intervals; group B (n = 8) dogs were put on ivermectin (600 microg/kg BW, subcutaneously, twice, 14 days apart) and oral prednisolone (0.5mg/kg BW, every 12h, for a total of 3 weeks, tapering the dose accordingly). Clinical and fecal examination as well as endoscopy, were performed on admission and at 20, 60 and 180 days from the beginning of the treatment. One group A dog responded poorly and died of pyothorax during the trial and another developed esophagitis due to accidental intraluminal ethanol infusion, only to experience an uneventful recovery. At different times during the 6-month follow-up period, there was a complete disappearance of the clinical signs in 4/6 group A dogs. However, full nodular regression was achieved only in one dog, and parasitic ova were still found in the feces of 4/6 dogs. At the same period of time in five group B dogs still available for evaluation, resolution of the clinical signs and complete nodular regression were seen in four and five animals, respectively, while negative fecal results were obtained in all dogs (8/8) of the same group 2 months from the beginning of the treatment. No significant difference was found between the groups, regarding the resolution of clinical signs, though group B dogs demonstrated a significantly higher rate of regression of esophageal nodules as well as negative fecal results, compared to group A dogs. The combination of ivermectin and prednizolone may be considered an effective treatment in the symptomatic and evidently asymptomatic esophageal spirocercosis of the dog. 相似文献

This phase II, randomized, open-label field trial was designed to evaluate and compare the safety and efficacy of four treatment durations (10, 20, 28 or 40 days) with marbofloxacin administered orally at the dosage of 2mg/kg once a day for canine visceral leishmaniosis. Twenty-four dogs naturally infected with visceral leishmaniosis and without biochemical disorder evidences of renal insufficiency, were recruited by two Greek veterinarian clinics. They were also randomly assigned to one of the four treatment duration groups, and have been clinically, haematologically, biochemically and parasitologically followed-up regularly for 9 months. Efficacy was achieved for 5/6 dogs treated for 28 days, 4/6 dogs treated for 10 or 20 days and for 3/6 dogs treated for 40 days. Moreover, efficacy was reached more quickly (58.4 days) in dogs treated for 28 days. Improvement of clinical signs tended to be better and faster in the 28 days treatment group too. After 9 months of follow-up, a total of three cases could be considered as relapsing (two dogs treated for 40 days and one dog treated for 28 days). There was a significant reduction in amastigotes density in macrophages after 3 months in the four groups when compared with the parasite density at inclusion. No adverse effects were noticed during this 9 months study. Results obtained with marbofloxacin at the dosage of 2mg/kg once a day for 28 days seem encouraging and may offer a safe alternative for treating canine visceral leishmaniosis. 相似文献

OBJECTIVE: To determine the efficacy and toxicity of chemotherapy in the treatment of canine nasal tumours. DESIGN: Retrospective clinical study PROCEDURE: Eight dogs with histologically confirmed nasal tumours were staged by means of complete blood count, serum biochemical analysis, cytological analysis of fine needle aspirate of the regional lymph nodes, thoracic radiographs and computed tomography scan of the nasal cavity. All dogs were treated with alternating doses of doxorubicin, carboplatin and oral piroxicam. All dogs were monitored for side effects of chemotherapy and evaluated for response to treatment by computed tomography scan of the nasal cavity after the first four treatments. RESULTS: Complete remission was achieved in four dogs, partial remission occurred in two dogs and two had stable disease on the basis of computed tomography evaluation. There was resolution of clinical signs after one to two doses of chemotherapy in all dogs. CONCLUSIONS: This chemotherapy protocol was efficacious and well tolerated in this series of eight cases of canine nasal tumours. 相似文献

Over a period of 10 days, 17 dogs became weak and developed neurological deficits of different degrees of severity. About 12 hours before these clinical signs appeared they had all eaten a particular brand of commercial dog food from a recently opened bag. They were all quadriparetic and hyporeflexic, and some of them also showed additional systemic or neurological signs, including dyspnoea, a high body temperature, tongue laxity, hyperaesthesia and anisochoria. Serum biochemical abnormalities included high activities of creatine kinase, lactate dehydrogenase and aspartate aminotransferase. Analysis of the suspect food revealed high concentrations of the ionophore lasalocid. Fifteen of the dogs were given supportive treatment at home and two were hospitalised. Five of the dogs died, but the others improved gradually and had fully recovered by one to four days after the appearance of the clinical signs. 相似文献

The susceptibility of dogs to experimental inoculation with trophozoites and cysts of human isolates of Giardia duodenalis and the clinical and laboratory profiles of infection of these animals were studied. Two groups (A and B), each comprising three dogs, were inoculated with G. duodenalis trophozoites and cysts, respectively. A third group of two dogs was not inoculated and remained as control. After inoculation feces were collected daily to determine the pre-patent period, by flotation in 33% zinc sulfate solution. Blood samples (5mL) were collected from animals at 15-day intervals during the 165 days of the experimental period and were used to carry out the hemogram and biochemical evaluation of the levels of total protein, albumin, alanine aminotransferase, gamma glutamyltransferase, urea and creatinine. A prepatent period was observed at 5-6 days post-inoculation (p.i.) in the inoculated dogs, with cysts eliminated for approximately 3 months. No alterations were seen in the clinical parameters evaluated. Anemia was observed at 15 p.i. in the inoculated dogs. The mean eosinophil count of inoculated groups was higher than that of the control (p< or =0.05) but none of the biochemical parameters analyzed presented significant differences. The results of this study show that G. duodenalis from human isolates is able to infect dogs with minimal systemic manifestations without producing clinical signs of giardiasis. 相似文献

Real-time PCR assay in Leishmania-infected dogs treated with meglumine antimoniate and allopurinol 总被引:1,自引:0,他引:1

A real-time PCR assay was exploited for monitoring the Leishmania DNA load in different tissues from 18 naturally-infected dogs before and after treatment with a combination of meglumine antimoniate (100mg/kg/day, subcutaneously) and allopurinol (10mg/kg/day, orally) for 30 days. After the combined therapy, allopurinol was continued at the same dose until the end of the observation period. Whole blood samples, lymph node aspirates, and skin biopsies were collected at the time of diagnosis, 1 month after starting therapy, and every 3 months for 2 years. In six dogs parasite load assessments continued every 6 months for a further 3 years. At each assessment, the dogs were examined for signs of disease and a clinical score was recorded. At diagnosis, the highest Leishmania DNA load was detected in lymph node aspirates. From 1-6 months post-therapy a general improvement in clinical conditions was recorded in all dogs, which correlated with a decrease in the parasite DNA load in all tested tissues, even though it was less pronounced in lymph node aspirates. In the period from 9-24 months post-therapy, a re-increase in parasite load was observed in the tissues of some dogs, concomitant with a disease relapse. The results show that the combined therapy with meglumine antimoniate and allopurinol promoted a clinical improvement which was accompanied by a reduction in the parasitic load in the blood, skin and lymph nodes but, even after long period of allopurinol administration alone, Leishmania may persist in dog tissues. 相似文献

Background
Every year many dogs in Sweden are bitten by Vipera berus, the only venomous viper in Sweden. This prospective study investigated clinical signs, some biochemical parameters, treatment, and progress of disease after snakebite in 53 dogs. Effects of treatment with and without glucocorticoids were evaluated.Methods
All fifty-three dogs bitten by Vipera berus were examined the same day the dog was bitten and the next day. Two more examinations during 23 days post snake bite were included. Creatinine, creatine kinase (CK), alanine aminotransferase (ALT), glutamate dehydrogenase (GLDH), alkaline phosphatase (ALP) and bile acid results were followed through 3 to 4 samplings from 34 of the dogs.Results
All dogs had variable severity of local swelling in the bite area and 73 per cent had affected mental status. Initial cardiac auscultation examination was normal in all dogs, but six dogs had cardiac abnormalities at their second examination, including cardiac arrhythmias and cardiac murmurs. All dogs received fluid therapy, 36 dogs were given analgesics, 22 dogs were treated with glucocorticoids, and ten dogs were treated with antibiotics. Evidence of transient muscle damage (increased CK) was seen one day after the snake bite in 15 (54%) of 28 sampled dogs. Moderate changes in hepatic test results occurred in 1 dog and several dogs (22 of 34) had transient, minor increases in one or more hepatic test result. No dog died during the observation period as a consequence of the snake bite.Conclusions
Snake bite caused local swelling in all dogs and mental depression of short duration in most dogs. Some dogs had transient clinical signs that could be indicative of cardiac injury and some other had transient biochemical signs of liver injury. Treatment with glucocorticoids did not have any clear positive or negative effect on clinical signs and mortality. 相似文献18.

A retrospective analysis was conducted of all feline necropsies performed during a nine year period to identify cases of sever, acute, centrilobular (periacinar), hepatic necrosis (ACHN). After exclusion of cats with anemia, a series of seven cases of ACHN was identified. In addition, two similar cases were identified from tissue submitted for histopathology following, and eight had bile duct hyperplasia. Seven of the nine cats received diazepam prior to dath, and one received zolazepam. Of the seven cats that received diazepam, five were healthy prior to treatment and received oral diazepam for the treatment of inappropriate urination, intercat aggression, or skin disease. Two cats which received diazepam exhibited other clinical signs: one had chronic vomiting, and the other received diazepam after biochemical evidence of hepatocellular necrosis was present. Onset of clinical sings in cats receiving oral diazepam occurred 7–13 days following the initiation of treatment. Clinical signs and clinical biochemical analysis were compatible with severe hepatocellular necrosis and acute liver failure. All cats had lesions in other organs: five had pancreatic disease, five had cardiac disease, and five had renal disease. All cats died, or were euthanized, within 4 dyas of the onset of clinical signs and 2 days after presentation to a veterinarian. Fatal, acute, centrilobular hepatic necrosis appears to be a serious adverse reaction to diazepam therapy in certain cats. 相似文献

BACKGROUND: Hemangiosarcoma (HSA) is a common solid tumor of the spleen, heart, and skin of dogs. Renal HSA represents an uncommon anatomic variant, with little reported about its biologic behavior and clinical outcome. HYPOTHESIS: That renal HSA is associated with longer survival than other visceral forms of HSA. ANIMALS: 14 dogs with renal HSA. METHODS: Medical records from 1999 to 2004 were searched for dogs with histopathologically confirmed renal HSA, and data relevant to clinical signs, treatments, and outcomes were abstracted. RESULTS: Clinical signs were nonspecific, and the median duration of clinical signs before diagnosis was 60 days. Two dogs presented in cardiovascular collapse secondary to hemoperitoneum. Common hematologic and biochemical abnormalities were anemia (9/14), hematuria (7/14), and proteinuria (7/14). One dog had pulmonary metastasis at diagnosis. All dogs had evidence of a renal mass visualized by abdominal radiography (14/14), ultrasound (9/14), or both. All dogs underwent nephrectomy, and 4/14 dogs also received adjunctive chemotherapy. Median survival time of all dogs was 278 days (range 0-1,005 days), and dogs with hemoperitoneum had significantly shorter survival times than dogs without hemoperitoneum (62 days versus 286 days, P < .001). CONCLUSIONS AND CLINICAL IMPORTANCE: These results indicate that hemoperitoneum and distant metastasis at diagnosis appear to occur less frequently in dogs with renal HSA compared with other visceral forms of HSA. Furthermore, dogs with renal HSA have protracted disease progression, with improved 1-year survival rates and longer median survival time compared to dogs with splenic, cardiac, and retroperitoneal HSA. 相似文献
