Ciclosporin is an immunosuppressive drug that has been used to treat allergies and other immune-mediated diseases in cats, dogs and humans. Information about the adverse effects of ciclosporin in cats has been limited to smaller studies and case reports. Adverse effects in dogs are mainly gastrointestinal in nature, but humans can also experience hypertension and altered renal function. The aim of this retrospective case series study was to document the occurrence and clinical appearance of adverse events in cats receiving ciclosporin to treat allergic skin disease. The medical records of 50 cats with allergic dermatitis treated with oral ciclosporin (1.9-7.3 mg/kg/day) were reviewed. Adverse events occurred in 66% (33 cats). Adverse events likely to be associated with ciclosporin included the following: vomiting or diarrhoea within 1-8 weeks of receiving ciclosporin (24%), weight loss (16%), anorexia and subsequent hepatic lipidosis (2%) and gingival hyperplasia (2%). Other adverse events less likely to be associated with ciclosporin therapy included the following: weight gain (14%), dental tartar and gingivitis (10%), otitis (4%), chronic diarrhoea (4%), inflammatory bowel disease with indolent gastrointestinal lymphoma (2%), urinary tract infection (2%), cataract (2%), elevated liver enzymes (2%), hyperthyroidism and renal failure (2%) and transient inappropriate urination (2%). Some cats experienced multiple adverse events. Case-control studies are needed to prove cause and effect of ciclosporin with regard to these adverse events.  相似文献

The efficacy and field safety of marbofloxacin (Zeniquin) for the treatment of superficial and deep bacterial pyoderma were evaluated. Seventy‐two dogs were treated with 2.75 mg kg?1 of marbofloxacin orally once daily for 21 or 28 days. Sixty‐two dogs (86%) had superficial pyoderma and 10 (14%) had deep pyoderma. A history of prior pyoderma was reported in 39/72 dogs. Pretreatment aerobic bacteriologic cultures of skin lesions were performed in 47 cases and the predominant pathogen isolated was Staphylococcus intermedius. Treatment was successful in 62/72 (86.1%) dogs, improvement was noted in 6/72 (8.3%) dogs and treatment failed in 4/72 (5.6%) dogs. Adverse effects associated with treatment included listlessness, anorexia, vomiting, soft stool, flatulence and polydipsia; these adverse effects were seen in only 6/81 dogs. Marbofloxacin was safe and effective for the treatment of superficial and deep pyoderma in dogs at the dosage used in this study.  相似文献

This double-blind randomized placebo-controlled trial indicates that Phytopica™ can be an effective glucocorticoid sparing agent in canine atopic dermatitis (AD). Twenty-two dogs with perennial AD [Canine Atopic Dermatitis with Severity Index (CADESI-03) ≥ 60] were given 200 mg/kg Phytopica™ or an identical placebo in food once daily for 56 days. All dogs were initially given 0.4 mg/kg methyl-prednisolone once daily, which was then adjusted according to the daily pruritus score (0–100 mm visual analogue scale). The cumulative dose and pruritus score were lower in the Phytopica™ than the placebo group. There were statistically significant time and treatment effects for the methyl-prednisolone dose and pruritus score, but there were no significant differences between the Phytopica™ and placebo groups in the proportion of dogs that achieved a > 50% reduction in dose or pruritus scores at day 56; the mean CADESI-03 scores at days 0, 28 and 56; the numbers achieving >50% reduction in CADESI-03 at days 28 and 56; or in the owners' global efficacy score at days 28 and 56. Adverse events included diarrhoea (three Phytopica™ and one placebo treated dog), polyuria/polydipsia (three dogs in each group), and polyphagia, intermittent anorexia and panting (one dog each in the placebo group). None of these by themselves required withdrawal of treatment.  相似文献

The aim of this systematic review was to identify, assess, and critically evaluate the quality of evidence of nonsteroidal anti‐inflammatory drug (NSAID)‐induced adverse effects in dogs. Original prospective studies published in peer‐reviewed journals in English (1990–2012) that reported data on the safety of NSAIDs administration in dogs were searched. For each study, design type (I, II, III, or IV) and assessment of quality (+, Ø, ?) were rated. For each drug, quantity and consistency rating (***, **, *) and strength of evidence (high, moderate, low, or extremely low) were identified and evaluated. The strength of evidence was defined in terms of how applicable and relevant the conclusions were to the target population. Sixty‐four studies met the inclusion criteria. Thirty‐five (55%) research studies and 29 (45%) clinical trials were identified. A high strength of evidence existed for carprofen, firocoxib, and meloxicam; moderate for deracoxib, ketoprofen, and robenacoxib; and low for etodolac. Quality and consistency rating were as follows: carprofen (***/***), deracoxib (**/***), etodolac (*/unable to rate), firocoxib (***/**), ketoprofen (**/***), meloxicam (***/***), and robenacoxib (**/**), respectively. Adverse effects were detected in 35 studies (55%) and commonly included vomiting, diarrhea, and anorexia. Three studies (5%) reported a power analysis related to adverse effects of ≥80%. In randomized, placebo‐controlled, blinded studies (n = 25, 39%), the incidence of adverse effects was not statistically different between treated and control dogs. Finally, most studies were not appropriately designed to determine the safety of NSAIDs, and involved a healthy nongeriatric population of research dogs.  相似文献

This study evaluated a 0.0584% hydrocortisone aceponate (HCA) spray (Cortavance®; Virbac SA, Carros, France) in canine atopic dermatitis (AD). Initially, dogs with a canine AD extent and severity index (CADESI-03) ≥ 50 were randomly allocated to receive HCA ( n  = 15) or placebo ( n  = 13) (two sprays from 10 cm away to treat an area of 100 cm2) once daily for 28 days. Twenty-one of the dogs then received HCA spray once daily, reducing to every other day or twice weekly over 42 days if improvement was maintained. CADESI, pruritus (14 cm visual-analogue-scale) and owner satisfaction (5-point scale) were recorded every 14 days. Haematology, biochemistry and adrenocorticotrophic hormone stimulation were performed at baseline, d28 and d70 (HCA n  = 9; placebo n  = 7). Intention-to-treat data were analysed. HCA spray significantly decreased CADESI (–61.4% versus –13.4%, P  = 0.0069) and pruritus (–38.8% versus +57.6%, P  = 0.0015) at d28 compared to placebo. Scores were significantly decreased at d14 (CADESI –50.5%, P  < 0.0021) and d28 (CADESI P  < 0.0001; pruritus P  = 0.018) compared to baseline following HCA but not placebo. At d28 11 of 15 and 7 of 15 HCA dogs had ≥ 50% reductions in CADESI and pruritus compared to 3 of 13 ( P  = 0.02) and 1 of 13 ( P  = 0.04) placebo dogs. Owner satisfaction scores were significantly higher in the HCA group (d28 P  = 0.0001). Daily 3 of the 21 dogs required daily maintenance therapy, 7 every other day, 6 twice weekly and 5 dogs required additional therapy. Coat length did not influence the results. No adverse effects or changes to blood parameters were noted. HCA spray proved safe and effective up to 70 days. It is not, however, licensed for long-term treatment.  相似文献

The aim of this study was to evaluate the efficacy and safety of aminoglutethimide in the treatment of dogs with pituitary-dependent hyperadrenocorticism (PDH). Ten dogs were diagnosed with PDH based on clinical and laboratory data, adrenal function tests (adrenocorticotropic hormone [ACTH] stimulation test and urinary cortisol/creatinine ratio [UCCR] combined with a high dose oral dexamethasone suppression test) and ultrasonographic evaluation of the adrenal glands. Aminoglutethimide was administered daily at a dose of 15 mg/kg bodyweight for one month. Median basal cortisol concentration and post-ACTH cortisol concentration one month after treatment were significantly lower than pretreatment values. Complete response was achieved in one dog, and partial response was obtained in three dogs. Severe side effects of anorexia, vomiting and weakness occurred in one dog and medication was withdrawn. Two further dogs developed decompensations of concurrent diseases and medication was stopped in these animals as well. Mild toxicity occurred in four dogs. Moderate to severe elevations in liver enzymes occurred in all dogs. The efficacy of this drug is lower than that observed using mitotane and ketoconazole, and adverse effects limit its use. Aminoglutethimide, using the protocol described, cannot be recommended for long-term management of PDH in the dog.  相似文献

OBJECTIVE: To assess the use of concurrent ketoconazole and low dose cyclosporin administration in a group of dogs with clinical evidence of perianal fistulas, and to determine if this combination could be used to manage perianal fistulas effectively. DESIGN: Prospective clinical trial PROCEDURE: Sixteen dogs with clinical evidence of perianal fistulas were given ketoconazole (10 mg/kg once daily) and cyclosporin (1 mg/kg twice daily initially) for 16 weeks. Blood cyclosporin assays were performed regularly and cyclosporin doses were altered to achieve a stable blood level above 200 ng/mL. Regular examinations assessed the dogs' general health, changes in clinical behaviour, fistula size and number. A complete blood count and serum biochemical analysis was performed in all dogs before and after the treatment period, and after 8 weeks of treatment in 12 dogs. Dogs were assessed for recurrence of lesions at 1, 3 and 12 months after the trial. RESULTS: All dogs showed marked improvement in lesions and behaviour within 14 days of the medication. Fourteen dogs completed the trial. Two dogs were excluded due to concurrent disease. Thirteen dogs (93%) showed complete resolution of fistulas during the treatment period. Seven dogs (50%) had no recurrence after 12 months. Recurrence was seen in three dogs (21%) at 8, 10 and 12 months after treatment, and in three dogs (21%) within 1 month of treatment. The medication was well tolerated. Side effects included transient anorexia, vomiting and lethargy in some dogs, increased shedding of hair and gingival hyperplasia. Ketoconazole administration allowed a dramatic reduction in cyclosporin dose (over 90% in 12 dogs and 80% in the other two) compared to previously reported cases treated with cyclosporin alone. CONCLUSION: The use of combined ketoconazole and cyclosporin provided an effective treatment for perianal fistulas. Outcomes were similar to those seen with cyclosporin alone, but allowed a significant reduction in cyclosporin dose and, therefore, cost. The use of immunosuppressive therapy in the treatment of perianal fistulas was effective and avoided many of the problems associated with surgical treament.  相似文献

Inflammatory colorectal polyp (ICRP), common in miniature dachshunds, presents with hematochezia, tenesmus and mucoid feces. Although an 80% response rate has been reported when treated with prednisolone and cyclosporine, effective treatment is needed for the remaining 20% of ICRP dogs. Leflunomide is an immunosuppressive drug reported as effective in several immune-mediated diseases. In the present study, we retrospectively evaluated the efficacy and adverse effects of leflunomide in 15 ICRP dogs that were refractory to treatment with prednisolone and cyclosporine. Treatment efficacy was assessed by endoscopy, clinical symptoms and rectal palpation. Adverse effects were determined by clinical symptoms and blood testing during follow-up. The leflunomide treatment response rate was 93.3%. The median dosage of leflunomide and the median response time were 3 mg/kg (range: 1.7–4.0 mg/kg) and 35 days (range: 20–119 days), respectively. Adverse effects observed included lethargy (3 dogs), anorexia (1 dog), respiratory symptoms (1 dog), leukocytopenia (2 dogs), thrombocytopenia (1 dog), anemia (1 dog) and liver enzyme elevation (8 dogs). Most of the adverse effects improved with symptomatic treatment and leflunomide discontinuation or dosage reduction. In conclusion, leflunomide treatment is effective in ICRP dogs refractory to treatment with prednisolone and cyclosporine. Because several adverse effects were observed, close monitoring is needed during leflunomide treatment follow-up.  相似文献

Sensitization to the dust mites was demonstrated by an intradermal (ID) skin test in 33 of 55 cats with Otodectes cynotis infestation. Positive ID test reactions to Dermatophagoides farinae were noticed in 32 (58.2%), to Dermatophagoides pteronyssinus in 29 (52.7%) and to Acarus siro in seven (12.7%) cats. The presence ( P  = 0.03) and duration ( P  = 0.04) of pruritus were positively associated with the ID test results. All the cats had a complete response to systemic ivermectin therapy, although three of them became reinfested as soon as they were in contact with other cats. The ID test was negative in 25 cats that had reacted positive previously, when the test was repeated 3–6 months after the acaricidal treatment. During that time there was no evidence of concurrent ectoparasitic infestation. The remaining eight cats were re-infested by O. cynotis or lost to follow-up.  相似文献

Twelve cats with generalized dermatophytosis were treated with ketoconazole (10 mg/kg of body weight, PO, with food, q 24 h). This treatment was successful in 8 cats, with resolution of lesions and negative findings on mycologic evaluation after 2 to 10 weeks (median duration, 6 weeks). One additional cat failed to improve initially, but complete resolution was achieved after the dosage of ketoconazole was doubled. Adverse effects in 3 cats included anorexia, weight loss, vomiting, and diarrhea.  相似文献

Thirty dogs with atopic dermatitis were given tepoxalin (Zubrin®, Intervet/Schering-Plough Animal Health, Boxmeer, the Netherlands) or placebo once daily for 4 weeks, followed by a wash-out period of 1 week before reversing the treatments. Pruritus was scored by the owners using the Edinburgh Pruritus Scale and one investigator employed a modification of the Canine Atopic Dermatitis Extent and Severity Index-01 (mCADESI-01) to score the physical lesions. After administration of tepoxalin there was a ≥ 50% reduction in pruritus and mCADESI-01 scores in 36% and 25% of the dogs, respectively, whereas following administration of the placebo there was a ≥ 50% reduction in pruritus and mCADESI-01 scores in only 25% and 16% of the dogs, respectively. Analysis of pooled data indicated that tepoxalin resulted in a significant reduction in pruritus ( P  = 0.012) and mCADESI-01 ( P  = 0.002) scores but there was no significant change after placebo. The median pruritus scores before and after tepoxalin were 2 (range 1–5) and 1 (range 0–5), respectively, and before and after placebo were 2 (range 0–4) and 2 (range 0–4), respectively. The median mCADESI scores before and after tepoxalin were 23 (range 0–68) and 16 (range 0–72), respectively, and before and after placebo were 18 (range 3–79) and 24 (range 0–65), respectively. At the dose used in this study (10.0–19.1 mg kg−1), tepoxalin was well-tolerated and no adverse effects were noted.  相似文献

Abstract The efficacy of twice daily topical application of capsaicin (0.025%) for the management of pruritus in dogs with atopic dermatitis (AD) was evaluated in double-blinded, placebo-controlled study. Twelve dogs with AD were randomly assigned to either 0.025% capsaicin or vehicle lotion applied twice daily for 6 weeks. After a 4-week wash-out period, treatments were switched. Significant improvement was reported by owners ( P  = 0.0006), but not by investigators. Owners noted temporary worsening of pruritus after the first week of capsaicin therapy. Overall capsaicin was well tolerated. Substance P (SP) concentrations in the skin did not correlate with the severity of the pruritus and did not change significantly over time and between treatments. Lesional skin had less SP than nonlesional skin ( P  = 0.03). These observations suggest that topical capsaicin should be further evaluated as an adjunctive antipruritic agent in dogs with AD.  相似文献

Cyclosporine A and ketoconazole were used as a combined therapy to treat 19 dogs with anal furunculosis. Complete resolution of all lesions was achieved in three to 10 weeks, but recurrences occurred in seven of the 19 dogs (36.8 per cent), with remission periods extending from one to six months for these dogs. Adverse effects of treatment included excessive hair loss, intermittent lethargy, vomiting and decreased appetite in some dogs, but none of the signs were considered serious. The results of treatment are comparable with, if not better than, the surgical alternatives. There is an approximate 70 per cent cost saving over the use of cyclosporine alone.  相似文献

Twenty-four Collies sensitive to the toxic effects of ivermectin, when administered at high dosages, were studied to evaluate the effects of repeated monthly treatment with an ivermectin beef-based formulation at amounts up to 10 times the dosage recommended for heartworm prevention in dogs. Collies were treated 3 times at 30-day intervals at rates of 12, 36, or 60 micrograms of ivermectin/kg of body weight, or with vehicle. Complete physical and neurologic examinations were performed on all dogs prior to the first treatment and after the final treatment. Clinical observations and ivermectin reaction scores were recorded daily for each dog throughout the study. Clinical or neurologic signs characteristic of ivermectin toxicosis were not observed for any dog during the study. Single episodes of vomiting were recorded for 2 vehicle-treated dogs and 2 dogs treated with ivermectin at 12 micrograms/kg from 6 to 21 days after treatment. At the end of the study, all dogs were challenge-exposed with ivermectin at 120 micrograms/kg to reconfirm their sensitivity to this class of compounds. All dogs developed signs typical of ivermectin toxicosis during the subsequent 48- to 72-hour period. Results of this study demonstrated that ivermectin can be administered repeatedly without adverse effects at rates up to 60 micrograms/kg (10 times the recommended use level) to Collies known to be sensitive to this drug.  相似文献

This double-blinded noninferiority clinical trial evaluated the use of oral fluconazole for the treatment of Malassezia dermatitis in dogs by comparing it with use of an accepted therapeutic agent, ketoconazole. Dogs presenting with Malassezia dermatitis were treated with either fluconazole or ketoconazole in addition to cephalexin for concurrent bacterial dermatitis. Statistically significant improvements in cytologic yeast count, clinical signs associated with Malassezia dermatitis, and pruritus were seen with both antifungal treatments. There was no statistical difference between the treatments with regard to the magnitude of reduction in these parameters. These results suggest that fluconazole is at least as effective as ketoconazole for the treatment of dogs with Malassezia dermatitis.  相似文献

The purpose of this study was to evaluate a combination of immunostimulatory bacterial DNA sequences and allergen-specific immunotherapy for the treatment of canine atopic dermatitis. Seven dogs with nonseasonal atopic dermatitis diagnosed by history, clinical signs and exclusion of differential diagnoses were included. All dogs had been on allergen-specific immunotherapy for at least 12 months with incomplete responses, were on additional antipruritic therapy and showed residual pruritus. Pruritus was marked by the owner on a visual analogue scale, lesions were determined by a clinician using the Canine Atopic Dermatitis Extent and Severity Index (CADESI), and concurrent medications were recorded before entering the study and after 14 weeks of treatment. Peripheral blood mononuclear cells were isolated and cultured; canine cytokine message for IFNγ, IL-4, TNF and IL-10 was quantitated using RT-PCR. A mixture of allergen extract and liposome-DNA complexes was injected intradermally at the beginning of the study and after 2, 4, 6, 10 and 14 weeks. CADESI, pruritus and medication scores, and cytokine messages at the beginning and end of the study were compared with a paired t -test. There were significant improvements in pruritus scores ( P  = 0.0277). Reductions in medication scores and CADESI were not statistically significant. IL-4 production decreased significantly ( P  = 0.0428); decreases in other cytokines were not significant. Although the number of dogs in this pilot study was small, the results warrant further investigation of a combination of immunostimulatory bacterial DNA sequences and allergen-specific immunotherapy for the treatment of canine atopic dermatitis.

Forty per cent of the members of the Norwegian Small Animal Veterinary Association (NSAVA) returned a questionnaire regarding the treatment and diagnosis of canine nasal mite infection in their practices in 1996. A total of 2392 dogs were treated for this infection by 156 NSAVA members in clinical practice in that year, averaging 15.3 treated dogs per veterinarian. An estimated minimum of 6000 Norwegian dogs were treated for nasal mite infection in 1996, at an estimated cost of treatment exceeding 3.3 million NOK. Fifty-nine per cent of the practitioners included at least a case history and clinical examination as diagnostic criteria prior to initiating treatment for nasal mite infection. Fewer than 10% routinely performed more thorough diagnostic procedures, and only 1.8% of the diagnoses were verified prior to treatment. A total of 27 different treatment regimens, involving either subcutaneously injected ivermectin or orally administered milbemycin oxime, were routinely used by NSAVA veterinarians to treat these dogs. Seventy-two (53%) of the veterinarians used ivermectin exclusively, 14 (10%) used milbemycin oxime exclusively, while 50 (37%) used both ivermectin and milbemycin oxime. No other drugs were used. Evaluation of treatment was made by assessing resolution of the clinical signs following treatment, and 97% of the veterinarians were satisfied with the effect of the treatment regimen they used. Adverse side-effects following treatment for nasal mite infection in 1996 were seen on 9 occasions; 4 following ivermectin administration and 2 following milbemycin oxime treatment, while in 3 cases no information on the drug used was provided. The risk of adverse reactions to treatment of nasal mite infection in dogs was 0.4%.  相似文献

Background

Effective treatments for dogs with advanced stage mast cell tumors (MCT) remain a pressing need. A micellar formulation of paclitaxel (paclitaxel [micellar]) has shown promise in early‐phase studies.

Hypothesis/Objectives

The objective was to demonstrate greater activity for paclitaxel (micellar) compared with lomustine. The null hypothesis was μp = μL (ie, proportion of responders for the paclitaxel [micellar] and lomustine groups, respectively).

Animals

Two hundred and fifty‐two dogs with advanced stage nonresectable grade 2 or 3 MCT.

Methods

Prospective multicenter randomized double‐blind positive‐controlled clinical trial. The primary endpoint was confirmed overall response rate (CORR) at 14 weeks. A secondary endpoint, biologic observed response rate (BORR), also was calculated. Safety was assessed by the characterization and grading of adverse events (AE).

Results

Overall CORR (7% versus 1%; P = .048) and BORR (23% versus 10%; P = .012) were greater for paclitaxel (micellar) compared with lomustine. Paclitaxel (micellar)‐treated dogs were 6.5 times more likely to have a confirmed response and 3.1 times more likely to experience a biologic observed response. The majority of AE with paclitaxel (micellar) were transient and clinically manageable. Twenty‐seven dogs (33%) receiving lomustine were discontinued because of hepatopathy compared with 3 dogs (2%) receiving paclitaxel (micellar) (P < .0001; odds ratio 26.7).

Conclusions and Clinical Importance

Paclitaxel (micellar)'s activity and safety profile are superior to lomustine. The addition of an active and novel taxane to the veterinary armamentarium could fill a substantial need and, as its mechanism of action and AE profile do not overlap with currently available TKI, its availability could lead to effective combination protocols.  相似文献

Canine atopic dermatitis (AD) is common and new therapies are beneficial. This multicentric, randomized, double-blind, placebo-controlled study tested the efficacy of Actinidia arguta (hardy kiwi) (EFF1001) in dogs with mild/moderate AD. The study was divided into two stages. Stage 1 lasted 6 weeks. In the first 2 weeks prednisolone [days 1–3: 0.2 mg/kg twice daily (BID), days 4–14: 0.2 mg/kg every other day (EOD)] was administered. Responsive dogs were placed on prednisolone 0.2 mg/kg EOD + assigned test article [either placebo or EFF1001 (30 mg/kg)] once daily for 4 weeks. Stage 1 responders were advanced to stage 2, which involved 4 weeks of just EFF1001. Clinicians scored lesions using Canine Atopic Dermatitis Extent and Severity Index (CADESI) and owners scored pruritus using a Pruritus Visual Analogue Scale. Seventy-seven dogs were enrolled, 76 were randomized on day 14, and 57 (57/76 = 75%) completed stage 1 (27 in EFF1001 and 30 in placebo). At the end of stage 1, 35 of 57 dogs (35/57 = 61%) responded (18 in EFF1001 and 17 in placebo) and advanced to stage 2. At completion of stage 1, CADESI scores did not significantly differ between groups while pruritus decreased in EFF1001 group and approached significance. At completion of stage 2, 19 dogs (19/35 = 54%) responded (15/19 = 79% had received EFF1001 and 4/19 = 21% placebo in stage 1). After completing stage 2, dogs placed on EFF1001 throughout the study were 3.5 times more likely to either maintain or improve scores than those that started it in stage 2. It is concluded that EFF1001 is beneficial adjunctive therapy after prolonged use.  相似文献
