Treatment of ethylene glycol toxicosis in cats.

Ethylene glycol (EG) was orally administered to 27 cats at dose levels of 4, 6, or 8 ml/kg of body weight. Treatment was initiated 4 or 8 hours later and consisted of giving (intraperitoneal injection, IP) 5 ml of 20% ethanol in isotonic saline solution and 6 ml of 5% sodium bicarbonate in isotonic saline solution per kilogram of body weight. Treatment was repeated every 6 or 8 hours for approximately 56 hours after initial treatment was given. The 6 control cats (i.e., untreated) and all cats treated 8 hours after EG was given in doses of 6 ml/kg (4 cats) or 8 ml/kg (4 cats) died. Only 1 of 4 cats (25%) recovered in the group given EG at the dose level of 4 ml/kg of body weight and initial treatment started 8 hours later. Two of 3 cats (67%) recovered in each of the groups given EG at the dose levels of 4 ml/kg and 6 ml/kg and initially treated 4 hours after dosing, but only 1 of 3 cats (33%) recovered in the group given 8 ml of eg/kg and first treated 4 hours later. Limitations of successful treatment are high doses of EG and delays in initiating the treatment.

[Progressive retinal atrophy in Abyssinian and Somali cats in the Netherlands (1981-2001)].

From 1981 to 2001, 248 Abyssinian and 127 Somali cats in the Netherlands were examined for hereditary eye disease. Distinct ophthalmoscopic signs consistent with hereditary progressive retinal atrophy (PRA) were observed in 11 Abyssinian cats, and subtle signs in 3 Abyssinian cats. A familial relationship was detected in 13 out of 14 of these cats, which supports a hereditary basis to the condition. Distinct funduscopic signs of retinal degeneration were observed at a median age of 4 years. One cat with advanced retinal degeneration was only 7 months old, whereas the remaining 10 cats were between 2 and 12 years old at the time of diagnosis. These differences in the age of onset are suggestive of at least two types of PRA occurring in Abyssinian cats in the Netherlands: a dysplastic, early-onset and a late-onset retinal degeneration. A large-scale and systematic examination programme for hereditary eye disease will be necessary to assess the incidence of PRA in the Dutch population of Abyssinian and Somali cats as a whole, and to provide a basis for a preventive breeding programme.

Association between feline immunodeficiency virus antibodies and host characteristics in Finnish cats.

Toward the end of 1989 the largest private veterinary laboratory in Finland (Vet/lab) began using a commercial combined ELISA test for Feline Immunodeficiency Virus (FIV) antibodies and Feline Leukemia Virus (FeLV) antigens (Cite Combo). The overall proportion of FIV seropositive feline samples was 5% during the 22 month study period. The number of tests performed increased slowly while the positive test results decreased with time (7% in 1990 and 4% in 1991). The decrease in prevalence was assumed to reflect a change in the sample population rather than an actual change in the general cat population. There were more symptomatic and domestic cats tested in 1990 than 1991. The lower-risk groups in the second year of the study may simply be an indication that the cat owners became more aware of FIV and the motivation to send samples switched from the veterinarian's interest to diagnose the disease in a symptomatic cat to the owner's interest to survey their cats for possible FIV infection. In a multivariable analysis, breed, symptoms, age and sex were associated with the risk of FIV seropositivity. The risk increased faster with age in males than in females (i.e., the age effect was not constant between sexes). The cats with symptoms had a higher risk than those without symptoms and non-purebred cats were at a higher risk than purebred cats. FeLV infection was not associated with FIV.

[The health impact of stray and wild cats in the human environment].

The population of stray cats in towns expands due to irresponsible behaviour of humans who allow them to enter cellars, hot water canals, store rooms etc. As a result of frequent feeding some specimens become tame, lose their shyness and on contact with humans and domestic animals they can become the source of some infectious agents. The most important of thus transmitted diseases is rabies. Cats become infected from foxes on rubbish heaps on the periphery of communities. More than 60% of cases of rabies of domestic animals are found in cats. Toxoplasmosis--cats excrete the infectious stage of the causal agent in their excreta. In the same manner also the agent causing intestinal salmonelloses is excreted. More than 5% cats are infected. Via excreta also the causal agents of toxocariasis are spread--the larvae of cat thread worms settle in the internal organs of humans (larva migrans). The assumed incidence in cats is as high as 50%, as suggested also by the high positivity of specimens from children playgrounds. Stray cats may be the source of agents causing various dermatomycoses and of ectoparasites.

Effects of a dietary chitosan and calcium supplement on Ca and P metabolism in cats.

The aim of the present study in cats was to investigate the potential effects of a calcium carbonate and chitosan supplement on blood parameters in aged cats with moderate chronic renal failure and on the mineral balance in adult healthy cats. For the trials, 10 neutered cats 2-4 years of age were fed for 21 days and six neutered cats (2 male and 4 female), 14 years of age, with elevated urea and phosphorus level in the plasma were fed for 35 days with a supplement. The apparent digestibility of phosphorus was (p < 0.05) reduced in the treatment period. Plasma urea inorganic phosphate decreased significantly (p < 0.05) in the old cats after 35 days of treatment. The treatment had a significant effect on the phosphorus, gross energy, dry matter, crude ash, crude fiber and crude protein digestibility in adult healthy cats. The practical implication could be an alternative treatment option for cats refusing to ingest veterinary renal diets.

Serum hyperviscosity syndrome associated with multiple myeloma in two cats.

Serum hyperviscosity syndrome was diagnosed in 2 cats with multiple myeloma. Clinical signs included pale mucous membranes, dehydration, retinal hemorrhages, dilated and tortuous retinal vessels, seizures, head-tilt, nystagmus, systolic murmur, and gallop rhythm. Laboratory abnormalities included hyperglobulinemia, azotemia, hyperphosphatemia, nonregenerative anemia, and thrombocytopenia. Both cats had IgG monoclonal gammopathy, Bence Jones proteinuria, increased numbers of bone marrow plasma cells, and high values for relative serum viscosity. Renal disease was suspected in both cats. Cardiac hypertrophy was documented in 1 cat and was suspected in the other cat. Chemotherapy, using melphalan, prednisone, and vincristine, caused short-term remission in both cats, and plasmapheresis was used to lower serum protein concentration in 1 cat. Serum hyperviscosity syndrome rarely develops in cats, but should be suspected when monoclonal gammopathy exists with signs of neurologic, cardiac, or retinal disease.

Perineal hernia in 3 cats.

Cases of perineal hernias in three cats are described. All the cats were male (2 castrated, 1 intact). The hernias were situated between the external anal sphincter and the levator ani muscle. The hernial sac contained a dilated rectum filled with fecal content (2 cats) as well as a small amount of retroperitoneal fatty tissue (2 cats) and urinary bladder (1 cat). A standard perineal herniorrhaphy in two cats, and herniorrhaphy via elevation of the internal obturator muscle in one cat were performed. No recurrence of the problem was observed in two cats during 9 months following the surgery. In one case, mild stretching of the pelvic diaphragm was noted with sporadic mild defecation problems observed after a 12-month period.

[Serum creatine kinase activity in dogs and cats with metabolic diseases].

Elevated Creatine kinase-activitiy (CK) indicates disturbances of the muscle cell integrity. In addition to primary muscle disease, like trauma, inflammation or dystrophy, diseases of other organs can lead to secondary muscle involvement, which will be indicated by increased serum activities of the CK. The mechanisms of muscle cell disturbance are still unknown. An elevated protein catabolism in the muscle cell is suspected. In the present study we investigated, if dogs and cats with metabolic diseases have increased CK-activity in the serum. From 34 dogs and cats in a group with different metabolic diseases without metabolic acidosis 19% of the dogs and 50% of the cats had increased CK-activity in the serum. From 33 dogs and cats with different metabolic diseases connected with metabolic acidosis 86% of the dogs and 95% of the cats had simultaneously increased CK-activity in the serum. In comparison to healthy dogs and cats animals with metabolic diseases have significant and in cases of metabolic di-seases with metabolic acidosis cats have high significant elevation (dogs significant) of CK-activity in the serum. There was no significant correlation between the groups of patients. In conclusion we think that our results show that metabolic diseases often induce secondary myopathy, measured by CK-activity in the serum, but metabolic acidosis has no direct influence on elevated CK activity in dogs and cats.

Evaluation of praziquantel for treatment of experimentally induced paragonimiasis in dogs and cats.

Praziquantel was used successfully for treatment of a small number of dogs and 1 cat infected with Paragonimus kellicotti. To further evaluate the usefulness of this drug in treating such infections, 7 cats and 7 dogs were inoculated orally with metacercariae (12 and 20 to 22, respectively) obtained from crayfish, then were treated after the infections became patent; 2 cats and 2 dogs served as noninfected controls. Beginning 1 week before infection, and continuing weekly thereafter, physical, hematologic, and fecal examinations were performed on each animal; thoracic radiography was performed every other week. By postinoculation week 6, all dogs given metacercariae had patent infection diagnosed on the basis of positive results of fecal examination. By postinoculation week 7, 5 cats had confirmed patent infection, but 2 cats given metacercariae never had patent infection or had signs of infection. Clinical signs of infection were minor and included increased respiratory tract noise, slight inducible cough, or mild dyspnea. Transient eosinophilia was detected in dogs around postinoculation week 3. Pretreatment radiography revealed cavitated lesions in cats only; pleural lines and patchy infiltrates in cats and dogs; or pneumothorax in dogs only. The treatment regimen consisted of 23 mg of praziquantel/kg of body weight given every 8 hours for 3 days; 1 infected cat and dog were not treated. By 11 days after treatment, eggs had disappeared from the feces of infected animals, and marked resolution of lung lesions was evident radiographically.(ABSTRACT TRUNCATED AT 250 WORDS)

Transfusion of type-A and type-B blood to cats.

Although nearly all domestic shorthair and longhair cats have type-A blood (greater than 99%), the frequency of blood type B in various feline breeds ranges from 0 to 59%. All blood-type-B cats have strong natural alloantibodies, predominantly of the IgM class, whereas blood-type-A cats have low alloantibody titers of the IgG and IgM classes. We therefore studied the efficacy and safety of transfusing 20 ml of matched and mismatched 14C-potassium cyanate-labeled blood to cats. In autologous and allogeneic matched transfusions of blood-type-A and type-B cats, the half-life of labeled erythrocytes proved to be similar (29 to 39 days). In contrast, type-B erythrocytes transfused into 5 blood-type-A cats had a mean (+/- SD) half-life of only 2.1 +/- 0.2 days and induced minor transfusion reactions. Half of the type-A blood given to 4 blood-type-B cats was destroyed within minutes to 6 hours (mean +/- SD = 1.3 +/- 2.3 hours), depending on the alloantibody titer. After 1 day, none of the labeled erythrocytes were detected. Mismatched transfusions in blood-type-B cats caused marked transient reactions including systemic anaphylactic signs (hypotension, bradycardia, apnea, urination, defecation, vomiting, and severe neurologic depression) and hemolytic signs (hemoglobinemia and pigmenturia) associated with severe reduction in plasma alloantibody titer and complement activity.(ABSTRACT TRUNCATED AT 250 WORDS)

Risk factors for Haemobartonella felis infection in cats.

A seroepidemiologic survey for Haemobartonella felis infection in cats of Wake County, NC was undertaken. To help assess risk factors, cat owners completed a 10-item questionnaire. Additionally, blood samples were obtained for determination of H felis presence, FeLV infection, and anemia. Prevalence rates for H felis presence were as follows: all cats, 4.9% (6/123); healthy cats, 3.6% (3/83); and ill cats, 7.5% (3/40). The estimated relative risk for haemobartonellosis was also increased in cats with any of the following: anemia, FeLV-positive status, lack of vaccinations, history of catbite abscesses and/or anemia, age less than or equal to 3 years, or outdoor-roaming status. The sex, breed, number of cats in the household, or presence of fleas were not significant factors, although ill male cats had a greater estimated relative risk for haemobartonellosis.

Clinical, radiographic, and bronchial cytologic features of cats with bronchial disease: 65 cases (1980-1986).

Medical records, radiographs, and bronchial cytologic abnormalities of 65 cats with bronchial disease were reviewed. Bronchial disease was defined as abnormality of the lower airways to the exclusion of disease originating or mainly involving the alveoli, interstitium, vasculature, or pleura. Cats with bronchial disease were more likely to be female and older. Siamese cats were overrepresented and had more chronic disease. In order of frequency, the following clinical signs were reported: coughing, dyspnea, occasional sneezing, wheezing, and vomiting. Radiography revealed prominent bronchial markings, with some cats having collapse of the middle lobe of the right lung (n = 7), overinflation of the lungs (n = 9), or aerophagia (n = 13). Of 65 bronchial washes, 58 were considered exudative, with the predominant cell type being eosinophil in 24%, neutrophil in 33%, macrophage in 22%, and mixed population of cells in 21%. Cultures for bacteria were considered positive in 24% of the cats. Circulating eosinophilia was not helpful in predicting the predominant cell type in bronchial cytologic exudates. Hyperproteinemia without dehydration was present in a third of the cats, indicating an immunologic response. Half the cats had resolution of clinical signs, whereas half the cats required continuing medication with bronchodilators, antimicrobial agents, or corticosteroids.

Evaluation of antithrombin-III activity as a coindicator of disseminated intravascular coagulation in cats with induced feline infectious peritonitis virus infection.

Six adult specific-pathogen-free cats were inoculated intraperitoneally with a cell culture-adapted strain of feline infectious peritonitis virus. Plasma samples were evaluated for antithrombin-III (AT-III) activities at post-inoculation days (PID) 0, 4, and 11 and at termination on PID 16 (1 cat) or 21 (5 cats). Other hemostatic values evaluated were activated partial thromboplastin times, prothrombin times, thrombin times, fibrinogen, platelet counts, and fibrin/fibrinogen degradation products. Antithrombin-III activity remained within normal or above normal range (89 to 246%) in all cats, with the exception of one cat on PID 4 (AT-III, 70%). Mean baseline AT-III activity for 6 cats at PID 0 was 123%. Mean AT-III activity on PID 4, 11, and 16 or 21 was 98, 162, and 130%, respectively. On PID 4 and 16 or 21, results of coagulation screening tests indicated that all cats had disseminated intravascular coagulation. Histologically, cats also had severe fibrinonecrotizing thrombovasculitis.

Collection of bronchoalveolar lavage fluid in cats, using an endotracheal tube.

Bronchoalveolar lavage fluid was collected from 12 anesthetized cats by use of an endotracheal tube and syringe adapter. The safety of the technique was evaluated by monitoring mucous membrane color, capillary refill time, pulse rate, respiratory rate, ECG, and arterial blood gas tensions and by necropsy findings. Group A consisted of 3 cats that were administered (by lavage) 4 aliquots of 20 ml of saline solution during anesthesia for placement of femoral artery catheters. Group B consisted of 4 cats that were administered a smaller total volume of saline solution (3 aliquots of 5 ml/kg of body weight) during a separate anesthetic period, other than the one for placement of catheters. Group C consisted of 5 cats administered 3 aliquots (5 ml/kg) of saline solution during a separate anesthetic period and administered supplemental oxygen for 5 to 10 minutes before and for 20 minutes after the lavage procedure. Group-A cats had a prolonged recovery period that was attributed to the lengthy anesthetic period required for placement of femoral catheters. The effect was eliminated in the cats of the other groups in which the lavage procedure itself accounted for only 5 to 10 minutes of anesthetic time. Evaluation of mucous membrane color, capillary refill time, ECG, pulse, and respiratory rate revealed no persistent abnormalities. Transient increase in pulse and respiratory rate was seen in some cats. Blood gas analysis revealed noticeable decrease in arterial oxygen pressures (Pao2) after the lavage procedure. In group-C cats, oxygen supplementation allowed the maintenance of normal or above normal Pao2.(ABSTRACT TRUNCATED AT 250 WORDS)

Horner's syndrome in dogs and cats: 100 cases (1975-1985).

The medical records of 74 dogs and 26 cats with Horner's syndrome (HS) that were admitted to the New York State College of Veterinary Medicine between January 1975 and October 1985 were reviewed. In dogs, but not cats, HS was associated significantly (P less than 0.01) with increasing age. Dogs with hypothyroidism (defined liberally but not rigorously), intracranial neoplasia, or thoracic neoplasia, cats with otitis media/interna (defined liberally), and dogs and cats with brachial plexus root avulsion were at greater risk for developing HS than were animals that were hit by a car. Dogs and cats with otitis externa were at less risk of developing HS than were animals that were hit by a car. The cause of HS could not be determined in 50% of dogs and 42.3% of cats. The results of topical adrenergic drug testing in dogs were inconclusive in localizing lesion site. In dogs and cats, HS appeared to be unassociated with gender, breed, or right vs left side. The important causes of HS in dogs and cats were trauma (hit by car), brachial plexus root avulsion, intracranial and thoracic neoplasia, and otitis media/interna.

Non-lymphoid hematopoietic neoplasia in cats: a retrospective study of 60 cases.

Sixty cats with hematologic abnormalities indicative of non-lymphoid hematopoietic neoplasia were classified into two groups, myelodysplastic syndromes (MDS) and acute myelogenous leukemias (AML), using criteria developed for human patients with similar diseases. Cats with myeloblast counts in bone marrow of less than 30% were classed as MDS and cats with myeloblast counts of 30% or greater were classed as AML. The clinical, laboratory, and postmortem findings in each group were described and compared. Clinical signs of disease were similar in both groups, the most common being inappetance, lethargy, and weakness. Non-regenerative anemia, macrocytosis, neutropenia, and thrombocytopenia were frequent hemogram abnormalities in both groups. Diagnostically useful differences in physical and peripheral blood findings were a higher prevalence of splenomegaly and/or hepatomegaly, thrombocytopenia, and severe anemia in the AML group. Circulating myeloblasts were found only in cats in the AML group. Outcome of disease was similar in both groups; 85% of the cats in each group died or were euthanatized within one week of diagnosis. In cats that were necropsied, extramedullary leukemic infiltrates were found in all cats in the AML group and in none of the cats in the MDS group.

Attempted immunisation of cats against feline infectious peritonitis using canine coronavirus.

Specific pathogen free kittens were vaccinated with an unattenuated field isolate of canine coronavirus (CCV) either by aerosol or subcutaneously, and received boosting vaccinations four weeks later. Aerosolisation elicited a homologous virus-neutralising (VN) antibody response that increased steadily over a four-week period and levelled off one to two weeks after revaccination. The initial aerosolised dose produced an asymptomatic infection with excretion of CCV from the oropharynx up to eight days after vaccination; virus shedding was not detected, however, after the second inoculation. Cats vaccinated subcutaneously developed low VN antibody titres after the first CCV dose and experienced a strong anamnestic response after the second dose. Neutralising antibody titres then levelled off one to two weeks after revaccination at mean values somewhat lower than in cats vaccinated by aerosol. CCV was not isolated from the oropharynx after either subcutaneous dose. Four weeks after CCV boosting inoculations, vaccinated cats and sham-vaccinated control cats were divided into three subgroups and challenged by aerosol with the virulent UCD1 strain of feline infectious peritonitis virus (FIPV UCD1) at three different dosage levels. Five of six cats (including sham-vaccinated controls) given the lowest challenge dose showed no signs of disease, while all other cats developed lesions typical of feline infectious peritonitis (FIP). The five surviving cats developed FIP after subsequent challenge with a fivefold higher dose of FIPV. Thus heterotypic vaccination of cats with CCV did not provide effective protection against FIPV challenge.

Treatment and prognostic factors in lymphoma in cats: 103 cases (1977-1981).

The records of 103 cats with lymphoma that underwent chemotherapy were reviewed. Diagnosis was confirmed by cytologic or histopathologic examination of appropriate tissue specimens. Sixty-four cats (62%) had a complete response to chemotherapy (median survival time, 7 months); 21 cats (20%) had a partial response (median survival time, 2.5 months); and 18 cats had a minimal response (median survival time, 1.5 months). Seventy-seven cats (75%) died of recurrent or progressive lymphoma, 9 cats died of feline leukemia-related anemia, 13 cats died of unrelated causes, and 4 cats were alive. Stage of disease was significantly (P = 0.009) related to response to treatment, and stage of disease and FeLV status were both significantly (P = 0.002 and P less than 0.001, respectively) related to survival.
