Coelho ELJ, Antunes HMR, Silva TFD, Veggi NDG, Sousa VRF, Almeida ADBPFD. Prevalence and clinical findings of feline otitis externa in Midwest Brazil. Top Companion Anim Med 2024; 60:100876. [PMID: 38631427 DOI: 10.1016/j.tcam.2024.100876] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2023] [Revised: 04/13/2024] [Accepted: 04/13/2024] [Indexed: 04/19/2024]
Abstract
This study was conducted to evaluate the prevalence of otitis externa (OE) in cats using cytology, direct otoscopic examination, and parasitological examination through swabs and curettage, and to compare the accuracy between collection methods for parasitological examination. Direct otoscopic evaluation of the external auditory canal (right and left), swabs for cytological examination of the external auditory canal, and collection of cerumen for parasitological examination through swabs and curettage of 137 cats from a veterinary hospital care were conducted between March 2021 and March 2022. The influences of age, sex, habitat, street access, and the presence of fleas on OE were evaluated. Cytological evidence of OE was observed in 25.5 % of cats and was statistically associated with flea and mite parasitism. Otodectes cynotis was found in 13.9 % of the cats. Cocci and Bacilli were the secondary factors in 34.3 % and 22.9 % of cats with OE, respectively. The Malassezia genus was a secundary factor in 57.1 % of the cats with OE. The frequency of OE was high in cats receiving hospital care. O. cynotis was a frequent primary cause of OE in cats. The curette sampling method is a great option for diagnosing O. cynotis infestation due to its ease of use.

Abstract
BACKGROUND Studies indicate that 6% to 20% of feline patients have at least one dermatopathy. HYPOTHESIS/OBJECTIVE This retrospective study aimed to provide comprehensive information about the types of skin diseases, diagnosis methods, treatments and follow-up data in a hospital population of domestic cats in Iran. ANIMALS/MATERIALS AND METHODS The present survey of clinical observations was conducted on the medical records of 1825 individual cats brought to the Faculty of Veterinary Medicine, Ferdowsi University of Mashhad (Iran) over a 12-year period (2009-2020). RESULTS Feline dermatoses accounted for 154 (8.43%) of the 1,825 cats examined during the study period. The most prevalent dermatological manifestations in the studied population of 154 were erythema, macules, papules and/or pustules (36; 23.37%), alopecia (18; 11.68%) and erosive/ulcerative lesions (17; 11.03%). Specific dermatological diagnoses made were the following (in descending order, of 154): dermatophytosis (34; 22.07%), subcutaneous abscesses (16; 10.38%), atopic skin syndrome/environmental allergies (20; 10.38%), external parasites (15; 9.74%), otitis (10; 6.49%), flea infestation (6; 3.89%), food allergy (4; 2.59%) and primary pyoderma (2; 1.29%). Most lesions were observed in the head/face of cats (41 of 154; 26.62%) and their ears (39; 25.32%). Following treatment, 86 of 154 cats (69.35%) had complete remissions, 17 cats faced recurrent dermatoses and the owners of 21 cats were not satisfied. CONCLUSIONS AND CLINICAL RELEVANCE The prevalence of dermatoses among this cohort of Iranian cats is similar to that in other parts of the world. However, a noticeable difference was detected in the most prevalent dermatoses. To the best of our knowledge, this is the first study to assess the characteristics and outcomes of feline dermatological conditions in Iran.

Staphylococci isolated from cats in Italy with superficial pyoderma and allergic dermatitis: Characterisation of isolates and their resistance to antimicrobials. Vet Dermatol 2023; 34:14-21. [PMID: 36221849 DOI: 10.1111/vde.13127] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2022] [Revised: 07/15/2022] [Accepted: 08/04/2022] [Indexed: 01/07/2023]
Abstract
BACKGROUND In cats, superficial pyoderma traditionally is considered rare and few reports are available. There is a particular lack of studies concerning Staphylococcus species associated with pyoderma in subjects affected by allergic skin diseases. HYPOTHESIS/OBJECTIVES (i) To evaluate the association between Staphylococcus spp. and superficial pyoderma in allergic cats and (ii) to characterise isolated staphylococci and analyse their antimicrobial resistance patterns. ANIMALS Forty-one cats with allergic dermatitis and superficial pyoderma in Italy. MATERIALS AND METHODS Skin swabs were cultured for the isolation of Staphylococcus spp. Species identification was performed by matrix-assisted laser desorption/ionisation time of flight mass spectrometry and 16S-rRNA sequencing. Staphylococcus aureus isolates were further characterised by staphylococcal protein A gene-typing. Antimicrobial susceptibility was performed by the disk diffusion method. RESULTS Staphylococci were isolated from 36/41 cats sampled and 39 different isolates were identified. Uneven distribution of staphylococcal species was observed among different body locations. The 39 isolates were S. aureus (n = 15), S. felis (n = 10), S. pseudintermedius (n = 8) and other staphylococci (n = 6). Eight different S. aureus spa-types associated with human clonal complexes were identified. Antimicrobial resistance was observed to penicillin (56.4%), tetracycline (46.2%), enrofloxacin (33.3%), erythromycin (28.2%), amikacin (25.6%), clindamycin (23.1%), marbofloxacin (15.4%), gentamicin (12.8%), trimethoprim-sulfamethoxazole (10.3%), chloramphenicol (7.7%) and cefoxitin/oxacillin (5.1%). Fifteen isolates (38.4%) were multidrug-resistant while meticillin resistance was associated only with S. pseudintermedius. CONCLUSIONS AND CLINICAL RELEVANCE These results confirm that S. aureus, S. pseudintermedius, and S. felis are frequently associated with superficial pyoderma in allergic cats. Semi-synthetic penicillins remain a suitable first-line treatment in this study, yet the high prevalence of antimicrobial resistant isolates suggests that antimicrobial susceptibility testing should be performed routinely.

Flat-Faced or Non-Flat-Faced Cats? That Is the Question. Animals (Basel) 2023; 13:ani13020206.

Abstract
Persian and exotic shorthair cats are the most-popular brachycephalic breeds worldwide. This study aimed to explore differences in human-cat bonding, behavioural traits, perception of clinical breed-related problems, and the motivation for purchasing between brachycephalic cat owners (BCOs) and non-brachycephalic cat owners (NBCOs). Using an online questionnaire, human-cat bonding and cats' behavioural traits were explored using the CORS and Fe-BARQ scales, respectively. Breed-related problems and motivations for purchasing were explored only in BCOs. There were 278 BCOs and 250 NBCOs who completed the survey. Respiratory diseases resulted in being the main health problem of these breeds. Most BCOs were not aware of the incidence of these disorders in brachycephalic cats. Character and appearance were the main motivations for purchasing these breeds. Perceived emotional closeness (EC), cat-owner interaction (COI), and perceived cost (PC) mean scores were significantly higher in BCOs. Playfulness and affection-/attention-seeking scores were significantly higher in NBCOs. BCOs reported a significantly higher score for separation-related behaviours. The higher scores in separation-anxiety-related behaviours and in the EC and COI scales could be related mainly to the high level of care these breeds require. The motivation for acquiring brachycephalic breeds for good companionship seems in contrast with the lower scores obtained from BCOs for playfulness and affection-/attention-seeking.

Abstract
OBJECTIVES The aim of this study was to assess the efficacy of a new therapeutic regimen of oclacitinib for the control of feline atopic skin syndrome (FASS) and to correlate plasma levels of this drug with clinical effects. METHODS Twenty-eight client-owned cats with a clinical diagnosis of FASS were recruited. Oclacitinib was administered at 1 mg/kg q12h for 2 weeks and then at 1 mg/kg q24h for a further 2 weeks. At the study outset (D0), and 7 (D7) and 28 (D28) days after starting treatment, clinical lesions were assessed using a validated scoring system (SCORing Feline Allergic Dermatitis [SCORFAD]) and pruritus was graded via an adapted visual analogue scale (PVAS). At the same time points, plasma oclacitinib levels and haematological variables were measured. RESULTS Among 18 cats completing the study, PVAS and SCORFAD improved by ⩾50% in 61% and 88% of animals, respectively. Mean PVAS decreased significantly between D0 and D7 and between D0 and D28 (both P <0.001) but not between D7 and D28. Likewise, mean SCORFAD values decreased significantly between D0 and D7 and between D0 and D28 (both P <0.001) but not between D7 and D28. On D7 and D28, plasma oclacitinib concentrations varied widely from 0 to 1443.2 ng/ml and from from 0 to 1177.7 ng/ml, respectively. Oclacitinib concentrations showed no correlation with clinical effects (SCORFAD and PVAS). CONCLUSIONS AND RELEVANCE Oclacitinib emerged as being safe and effective to control clinical signs of FASS. A mean dose of 1 mg/kg, even without extending twice-daily treatment beyond the first 2 weeks, could be a suitable therapeutic regimen. Plasma drug levels did not seem useful to predict clinical response during treatment.

Abstract
The treatment regimen for feline pemphigus foliaceus (PF), an autoimmune disease caused by auto-antibodies against proteins of the desmosome junction, usually includes high doses of oral or parenteral immunosuppressive drugs, typically glucocorticoids. This case adds to a growing body of evidence that topical hydrocortisone aceponate is effective for the treatment of feline PF, and demonstrates the practical use of a non-invasive diagnostic method for histopathology when owners refuse a biopsy to support a clinical diagnosis of PF. Finally, this case highlights an international trend of owner-initiated treatment of feline infectious peritonitis (FIP) using unlicensed, unregistered drugs.

Abstract
Case summary A 7-year-old male domestic shorthair cat was presented with a non-pruritic erythematous crusted nasal hypotrichosis along with bilateral ceruminous otitis externa. The cat was diagnosed with diabetes mellitus and was positive for feline immunodeficiency virus (FIV). Deep skin scraping, trichograms from lesional skin and ear canal parasitological examination were positive for Demodex cati. A 250 mg (55.5 mg/kg) fluralaner spot-on for medium-sized cats (Bravecto; MSD) was applied to the base of the cat’s head. Re-examinations were carried out on the fourth, sixth and eighth weeks after therapy. On the fourth week, the ceruminous otitis had resolved completely and the nasal lesions were markedly improved. One dead adult D cati was found in deep skin scrapings while other tests from the skin and both ear canals were negative. On the second re-examination only a mild hypotrichosis persisted on the nasal region and all parasitological examinations were negative. Eight weeks after the initial examination, the skin lesions had almost clinically resolved. On the 12th week, fluralaner spot-on was repeated. No recurrence was noted at the 6-month follow-up. Relevance and novel information The use of isoxazolines has been reported for only a few demodectic cats but was described to be safe and effective. This is the first report to evaluate the efficacy of a single spot-on fluralaner for the treatment of localised dermatitis and otodemodicosis due to D cati, and suggests it as an effective, safe and practical treatment.

Abstract
BACKGROUND There are no liquid oral glucocorticoids labelled for management of pruritus and clinical lesions of feline hypersensitivity dermatitis (feline HD). HYPOTHESIS First, to demonstrate that dexamethasone sodium phosphate (DexSP, DexajectSP, Henry Schein; Dublin, OH, USA; 4 mg/mL), an intravenous glucocorticoid, can be absorbed by healthy cats when administered orally. Second, to demonstrate the efficacy of orally administered DexSP for reducing pruritus and clinical lesions in patients with feline HD. ANIMALS Seven healthy and 12 client-owned cats with HD. METHODS AND MATERIALS Healthy cats were administered a single dose of 0.2 mg/kg DexSP p.o. and serum concentrations were measured using enzyme-linked immunosorbent assay (ELISA). Feline HD patients were assessed with SCORing Feline Allergic Dermatitis (SCORFAD) and pruritus Visual Analog Scale (pVAS) at Visit 1 (V1) and after 20-31 days of receiving 0.2 mg/kg/day DexSP p.o. (V2). Complete blood cell counts, serum chemistry profile, and urinalysis were performed in 50% of feline HD patients at both visits. RESULTS Healthy cats had detectable serum concentrations of DexSP following oral administration; concentrations ranged from 0.7 to 92.3 ng/mL. Feline HD patients showed significant decreases in SCORFAD and pVAS scores from V1 to V2. CONCLUSIONS DexSP was absorbed when administered orally to healthy cats and 0.2 mg/kg/day DexSP is an efficacious dose to rapidly improve the pruritus and clinical lesions associated with feline HD.

Abstract
PRACTICAL RELEVANCE Chronic otitis can be one of the most frustrating diseases to manage for a small animal practitioner. While it occurs less commonly in the cat than the dog, it is no less challenging. The purpose of this review is to discuss the common and uncommon causes of chronic otitis in the cat within the clinical framework used for diagnosis and treatment. The focus is on diseases that affect the ear canal, rather than those restricted to the pinnae. CLINICAL CHALLENGES Otitis is multifactorial, which complicates management. A common clinical mistake is to focus solely on treating the infection present. Only by addressing all factors will a clinician successfully control chronic otitis. For the purposes of this review, the authors have adopted the established model of separating primary, predisposing and perpetuating causes of otitis. Primary factors are those that directly cause otitis (inflammation); predisposing factors are those that put the patient at risk for development of otitis; and perpetuating factors are those that result in ongoing clinical signs of otitis or that prevent clinical resolution. AUDIENCE This review is aimed at veterinarians who treat cats and particularly those with an interest in feline dermatology and otology. EQUIPMENT While many practitioners rely on a hand-held otoscope, a video-otoscope can be very helpful for the diagnosis and treatment of chronic otitis. EVIDENCE BASE This review presents up-to-date information regarding the diagnosis and treatment of chronic otitis in cats, with emphasis on the most recent peer-reviewed literature.

Abstract
BACKGROUND Feline atopic syndrome (FAS) is a common disease. Single intradermal injections of heat-killed actinomycetales have shown beneficial effects in canine allergies. HYPOTHESIS/OBJECTIVE To evaluate the clinical effects of heat-killed actinomycetales [Gordonia bronchialis (GB) and Rodococcus coprophilus (RC)], alone or in combination, in FAS. METHODS AND MATERIALS Privately owned cats with a diagnosis of FAS were assigned randomly in three treatment groups (GB, RC and GB/RC combination) or placebo. Five intradermal injections were performed over a one year period. At each visit [Day (D)0, D20, D40, D60, D90, D180 and D365], clinical signs, global owner assessment score, use of rescue medications, clinical adverse effects, skin hydration and cutaneous pH were assessed. RESULTS Seventeen cats were enrolled. When compared to the placebo group and improvement in treatment GB was sustained from D90. When compared with D0 significant improvement in the GB group was seen from D60. Over one year, a complete remission of the clinical signs was seen in 30-67% of cats in the treatment groups. A reduction in the pruritus score was seen for RC after 365 days of treatment (P = 0.04). Differences in the other variables were not seen. CONCLUSIONS AND CLINICAL IMPORTANCE The use of multiple intradermal injections of heat-killed GB shows promise as effective and well-tolerated treatment for FAS. Because of the low cost and the lack of adverse effects, GB could be a beneficial treatment option for FAS. A larger study is needed to confirm these data and to evaluate the immunological changes occurring in the treated cats.

Abstract
BACKGROUND Feline atopic syndrome (FAS) describes a spectrum of hypersensitivity disorders characterised by highly diverse clinical presentations including skin, gastrointestinal and respiratory systems. Among these disorders is feline atopic skin syndrome (FASS), in which hypersensitivity is typically associated with environmental allergens, although food allergy may coexist. Involvement of other organ systems (e.g. asthma) also may occur. Because of its highly heterogeneous clinical presentation, diagnosis of FASS can be challenging. OBJECTIVES A subgroup of the International Committee on Allergic Diseases of Animals was tasked to summarise the most current information on the clinical presentations of FASS and to develop diagnostic guidelines. METHODS AND MATERIALS Online citation databases and abstracts from international meetings were searched for publications related to feline allergic conditions. These were combined with expert opinion where necessary. RESULTS A total of 107 publications relevant to this review were identified. Compilation of these data enabled development of a detailed description of the clinical features of FASS and development of guidelines focusing on systematic elimination of other skin conditions with similar clinical characteristics. As allergen tests are frequently used by dermatologists to support a clinical diagnosis of FASS, a brief review of these methodologies was also performed. CONCLUSIONS AND CLINICAL IMPORTANCE In a similar way to atopic dermatitis in dogs, FASS is a clinical diagnosis based on the presence of compatible clinical signs and exclusion of other diseases with similar clinical features. Elimination or exclusion of fleas/flea allergy, other parasites, infections and food allergy is mandatory before reaching a diagnosis of FASS.

Abstract
BACKGROUND Sublingual immunotherapy (SLIT) has been deployed in humans and dogs; to the best of the authors' knowledge, there are no published studies about the use of SLIT in cats. OBJECTIVES Evaluate the clinical efficacy of SLIT in atopic cats sensitized to dust and storage mites, assessing immunological changes associated with SLIT treatment. ANIMALS Twenty-two client-owned cats with clinical signs compatible with feline atopic dermatitis (fAD) and serum allergen-specific immunoglobulin (Ig)E against house dust and storage mites. METHODS AND MATERIALS Prospective, multicentre, open-label clinical trial. Individualized mite-specific SLIT was administered orally for 12 months. All cats underwent clinical examination to record SCORing feline allergic dermatitis (SCORFAD), pruritus Visual Analog Scale (pVAS) and serum allergen-specific IgE and IgG, every three months for 12 months. RESULTS Sixteen of 22 cats (73%) completed the study and three of six cats withdrawn from the study were included in an intention-to-treat analysis. SCORFAD and pVAS values decreased significantly from baseline (T0) to the third month of treatment (P = 0.0004 and P = 0.0013, respectively), with median total values ranging from 19 (6-44) (T0) to 2.5 (0-17) (T12) (P = 0.0001), and from 8 (6-10) (T0) to 2.3 (0-8) (T12) (P = 0.0001), respectively. Allergen-specific IgE values decreased significantly from the ninth month (T9) of treatment (P = 0.0032), with median scores decreasing from 56 (12-729) (T0) to 34 (0-158) (T12) (P = 0.0208). No significant differences in allergen-specific IgG values were observed throughout the study. No adverse effects related to the use of SLIT were reported. CONCLUSIONS AND CLINICAL IMPORTANCE Sublingual immunotherapy should be considered a rapid, effective, safe and well-tolerated treatment in cats with feline atopic dermatitis fAD.

Abstract
BACKGROUND Circulating anti-keratinocyte immunoglobulin (Ig)G targeting desmosomal proteins have been identified in people and dogs with pemphigus foliaceus (PF). By contrast, detection attempts in PF-affected cats have been largely unsuccessful. HYPOTHESIS/OBJECTIVES To detect circulating anti-keratinocyte autoantibodies in PF-affected cats and determine their titres and tissue-staining patterns. ANIMALS Thirty PF-affected cats were compared to 11 specific-pathogen free, 15 healthy and 31 allergic cats. METHODS AND MATERIALS Sera were tested by indirect immunofluorescence on canine footpad and buccal mucosal substrates. RESULTS Circulating, anti-keratinocyte IgG with a suprabasilar, web-like (intercellular) pattern were detected in the majority of PF-affected cats (23 of 30, 77%), some allergic cats (six of 31, 19%) and one healthy cat (7%). Both footpad epidermis and buccal mucosa were positive in the majority of seropositive PF-affected cats (21 of 23, 91%), and in only one of six (17%) seropositive allergic cats. Staining was limited to the footpad in the remaining seropositive PF-affected and allergic cats and one seropositive healthy cat. Reciprocal IgG titres were significantly higher in PF-affected cats compared to controls (Dunn's post-test, P < 0.0001). Anti-keratinocyte IgM, IgA or IgE were not detected in any sera. CONCLUSIONS AND CLINICAL IMPORTANCE These results confirm the presence of circulating anti-keratinocyte IgG in a majority of PF-affected cats and in a small percentage of healthy and allergic cats. Although the molecular target and pathogenic nature of the antibodies remains unknown, the detection of positive immunostaining on buccal mucosal tissue, in addition to the footpad, suggests that the major target antigen of feline PF differs from that reported in dogs.

Abstract
Persian cats are a popular cat breed worldwide, and especially in the US, Europe and Asia. This study aimed to describe the demography, common disorders and mortality in Persians under general practice veterinary care in 2013 in the UK. The study population of 285,547 cats overall included 3235 (1.1%) Persians. Mean adult Persian bodyweight was 3.9 kg (SD 0.9) and median age was 7.0 years (IQR 3.3–11.6). At least one disorder was recorded in 2099 (64.9%) Persians. The most common specific disorders were haircoat disorders (411, 12.7%), periodontal disease (365, 11.3%), overgrown nails (234, 7.2%), and ocular discharge (188, 5.8%). The most common disorder groups were dermatological (578, 17.9%), ophthalmological (496, 15.3%) and dental (397, 12.3%). Median longevity was 13.5 years (IQR 9.9–16.0). The most common grouped causes of death were renal disease (102, 23.4%), neoplasia (37, 8.5%) and mass-associated disorder (35, 8.0%). This is the first study to use general practice data to examine the overall health of Persian cats. With haircoat, ocular and dental disorders being the predominant disorders identified, this study highlights the need for increased owner awareness to manage and prevent the typical health problems associated with this breed’s phenotype.

Abstract
Practical relevance: Awareness of the strong connection between observed behavior and physical and emotional health is essential for patient welfare. It is often a change in the individual's normal behavior that informs owners and veterinarians of the possibility of illness, pain and stress/distress. There is ample evidence in the feline literature that medical and behavioral health go hand in hand. In most feline cases, medical and behavioral conditions contribute concurrently to clinical signs. Clinical challenges: Our domestic cats do not express change in physiological and emotional states in a way that is easily recognized. Therefore, it can be difficult to diagnose medical and behavioral illnesses and ascertain contributions from each one to the final diagnosis. When various levels of stress are present, especially distress, this compromises behavioral and physical health, and influences treatment outcomes. AIMS This review is intended to help veterinarians recognize physical and behavioral changes associated with acute stress through to chronic distress, including stress-associated diseases. An emphasis on thorough history-taking will allow the clinician to ascertain which signs are behavioral and which are medical, with the understanding that they are not mutually exclusive. Equally important is the contribution of pain, chronic disease and poor environmental situations to behavioral changes and the expression of medical disorders. Evidence base: There is an increasing amount of evidence that stress and distress have profound effects on feline health, behavior and welfare. The authors have drawn on a substantial body of published veterinary research in producing this review.

Abstract
OBJECTIVES The aims of this descriptive study were to identify risk factors for feline Microsporum canis infection at shelter intake, to describe screening test accuracy, and to refine confirmatory testing time frames. METHODS Database records for the general feline population and intake data, medical records and fungal culture logs for cats diagnosed with M canis at a limited admissions shelter were accessed retrospectively for a period of 2 years. RESULTS The feline population at the study shelter had a prevalence of M canis of 1.8% (95% confidence interval [CI] 1.6-2.0%). Kittens were eight (95% CI 4.8-13.5) times more likely to present with dermatophytosis than adults. Although more cats presented with M canis during summer and autumn, season was not significant when the model was controlled for age. Owner-surrendered cats were half as likely (95% CI 0.41-0.77) as transported cats to be diagnosed with M canis. Wood's lamp examinations had a sensitivity of 66.8% (95% CI 60.2-73.4) and a specificity of 74.8% (95% CI 64.2-85.1) compared with dermatophyte test medium (DTM) culture. In 78.8% (95% CI 61-91) of littermate or household groups with mixed Wood's lamp results, all cats were DTM culture positive. Under consistent incubation conditions, 202/202 diagnostic DTM plates for M canis-infected cats showed recognizable colony growth before 7 days (median 4 days), and 19/19 fomite carrier cat cultures showed growth before 12 days (median 5 days). CONCLUSIONS AND RELEVANCE Applying the results of this study to shelter protocols could optimize diagnostic approaches and shorten the length of stay for shelter cats and kittens, resulting in streamlined shelter operations and improved feline welfare.

Abstract
BACKGROUND Since the first description of feline pemphigus foliaceus (PF) more than 30 years ago, numerous case reports have been published, while larger case series have remained rare. This large body of information, if extrapolated, could address clinical discrepancies and expand our knowledge about the treatment of feline PF. This manuscript reviews cases of feline PF published between 1950 and 2016 and adds additional 35 original cases to provide further insight into the clinical aspect and treatment outcome of this disease. RESULTS Feline PF, while being a primary acantholytic pustular dermatosis, presents most often with crusts and erosions that predominantly affect the face and feet. More than half of cats with active disease exhibits non-dermatological signs such as lethargy, fever and/or anorexia. The prognosis of feline PF is good as the majority of cats rapidly achieve disease control even with the most basic treatment such as glucocorticoid monotherapy. Most PF-affected cats, however, require long-term treatment and, like other autoimmune diseases, feline PF has a tendency to relapse spontaneously or with treatment changes. CONCLUSIONS Therefore, despite the overall good prognosis cats with PF can be given, owners should be informed and prepared for these circumstances, which may reduce the risk of euthanasia in the case of disease relapse, and improve treatment compliance.

Abstract
BACKGROUND Dermatophytosis is a superficial fungal skin disease of cats and dogs. The most common pathogens of small animals belong to the genera Microsporum and Trichophyton. It is an important skin disease because it is contagious, infectious and can be transmitted to people. OBJECTIVES The objective of this document is to review the existing literature and provide consensus recommendations for veterinary clinicians and lay people on the diagnosis and treatment of dermatophytosis in cats and dogs. METHODS The authors served as a Guideline Panel (GP) and reviewed the literature available prior to September 2016. The GP prepared a detailed literature review and made recommendations on selected topics. The World Association of Veterinary Dermatology (WAVD) provided guidance and oversight for this process. A draft of the document was presented at the 8th World Congress of Veterinary Dermatology (May 2016) and was then made available via the World Wide Web to the member organizations of the WAVD for a period of three months. Comments were solicited and posted to the GP electronically. Responses were incorporated by the GP into the final document. CONCLUSIONS No one diagnostic test was identified as the gold standard. Successful treatment requires concurrent use of systemic oral antifungals and topical disinfection of the hair coat. Wood's lamp and direct examinations have good positive and negative predictability, systemic antifungal drugs have a wide margin of safety and physical cleaning is most important for decontamination of the exposed environments. Finally, serious complications of animal-human transmission are exceedingly rare.

Abstract
Objectives This study was designed to confirm the efficacy and tolerability of a daily dose of 7.0 mg/kg (3.2 mg/lb) ciclosporin (CsA) in the treatment of feline hypersensitivity dermatitis (HD), as this includes some of the most frequently suspected skin diseases in cats and recent publications have reported the successful use of CsA in the treatment of feline HD. Methods In total, 217 cats with feline HD were treated daily for 42 days with a target dose of 7 mg/kg CsA (n = 144) or a placebo control (n = 73) administered either in the food or directly in the mouth following feeding. Clinical and dermatological evaluations were conducted on days 0, 21 and 42, or study exit. Safety was evaluated through physical examinations, clinical pathology and the monitoring of adverse events (AEs). Results Administration of CsA at 7.0 mg/kg produced a significant improvement in the total lesion score ( P <0.0001). The average reduction from visit 1 to visit 3 was 65.1% in the CsA group (9.2% for the placebo). In addition, owners assessed 78.3% of the cases in the CsA group as a success. Statistically significant recoveries were also seen in extent of lesions, investigator assessment of overall improvement, and mean improvement in both the investigators’ and owners’ assessment of pruritus. Mild gastrointestinal disorders were the most common AEs but did not require cessation of therapy. Conclusions and relevance Results confirm that 7.0 mg/kg CsA dosed daily in food or orally for up to 6 weeks is effective and well tolerated by cats with feline HD.

Abstract
Ciclosporin (Atopica oral solution for cats 100 mg/ml; Novartis Animal Health) was recently approved for use in cats with feline hypersensitivity dermatitis. The immunosuppressant effect of ciclosporin on the ability of cats to mount an immune response following vaccination was determined. Thirty-two healthy, immunocompetent adult cats (16 cats/group) were treated with either ciclosporin for 56 days at a dose of 24 mg/kg once daily or sham dosed. Prior to treatment, cats had an adequate antibody response to primary vaccination against feline calicivirus (FCV), feline herpesvirus-1 (FHV-1), feline panleukopenia virus (FPV), feline leukemia virus (FeLV) and rabies. Booster vaccination or novel vaccination with feline immunodeficiency virus (FIV) was administered 28 days after initiation of treatment with ciclosporin. There were no differences between the ciclosporin-treated and control cats for FCV and FPV antibody titers following booster vaccination. There were delays/reductions in antibody response to FHV-1, FeLV and rabies in treated cats; however, adequate protection was achieved in response to all booster vaccinations. Following primary vaccination with FIV, control cats showed a response, but treated cats showed no antibody production. Adverse events commonly associated with ciclosporin treatment, including diarrhea/loose stool, vomiting, salivation and regurgitation, were reported. In adult cats treated with 24 mg/kg/day of ciclosporin (more than three times the therapeutic dose), vaccine titer levels were adequate for protection following booster vaccination. In contrast, treated cats failed to mount a humoral response to a novel (FIV) vaccination, suggesting that memory B-cell immune responses remain intact during repeated high-dose ciclosporin administration in cats, but that primary immune responses are impaired.

Abstract
BACKGROUND Feline demodicosis due to Demodex cati is a rare skin disease often associated with concurrent disease and generalized immunosuppression. Local immunosuppression due to the application of topical immunomodulatory drugs, such as glucocorticoids and tacrolimus, or by tumour cells has been suggested as a potential trigger for development of localized demodicosis in humans and animals. OBJECTIVES The goal was to describe two cats with asthma that developed localized demodicosis on the muzzle as a result of chronic therapy with a glucocorticoid administered via dispensing inhaler mask. RESULTS In both cats, the muzzle area exposed to the fluticasone-dispensing chamber exhibited patchy alopecia, mild erythema, crusting and scaling. Deep skin scraping revealed D. cati. Discontinuation or reduction of fluticasone and administration of milbemycin resulted in resolution of clinical signs within 2 months in both cats. A negative skin scrape was obtained after 7 months of milbemycin in one of the cats. CONCLUSIONS AND CLINICAL IMPORTANCE Demodicosis should be considered as a possible differential diagnosis in cats with primary alopecia or other skin lesions on the face exposed to inhalant glucocorticoids. Minimization of contact between the inhalant glucocorticoid and the skin can be achieved by wiping residual powder from the face and by keeping the mask tightly pressed to the skin to avoid contact with the surrounding area.
