BackgroundCanine leishmaniosis (CanL) caused by Leishmania infantum is a widespread endemic disease in SW Europe. This study was designed to determine how veterinarians clinically manage CanL in this region by analysing information collected in a questionnaire completed by local veterinarians working in clinics in France, Portugal, Greece, Spain, Italy and Slovenia.MethodsOver the period 2004–2011, a questionnaire on CanL was sent to 12,546 small animal clinics located in the six countries surveyed. The questionnaire with 10 items comprising open and closed questions sought to obtain comparable data regarding the main clinical manifestations of CanL, the diagnostic methods used, the treatment regimens selected, recommended preventive measures and awareness of the important public health implications of CanL.ResultsThe data collected reflect similarities in the clinical manifestations reported although there was some variation in the concurrent diseases described, and wide variation in the clinical management of CanL among the countries examined in terms of dosing regimens, therapeutic agents and the criteria used to diagnose CanL. Most veterinarians properly informed dog owners about the preventive measures available and about the zoonotic implications of CanL.ConclusionsThis survey describes the current situation in SW endemic countries in Europe regarding the clinical management of CanL. The data collected reveal a need to unify criteria from evidence-based medicine to determine and similarly apply the best diagnostic and treatment methods available for this disease in the different countries.

Low levels of plasma vitamin E concentrations were found in canine atopic dermatitis (CAD). The present study was aimed at determining the effect of an eight-week vitamin E supplementation on clinical response (Canine Atopic Dermatitis Extent and Severity Index (CADESI-03) scores and pruritus intensity) in dogs with atopic dermatitis. Levels of oxidative stress markers (plasma malondialdehyde and total antioxidant capacity (TAC), blood glutathione peroxidase and erythrocyte superoxide dismutase, plasma and skin vitamin E concentrations) were also determined. Twenty-nine dogs with CAD were included in the study. Fourteen received vitamin E (8.1 IU/kg once daily, orally) and 15 received mineral oil as placebo (orally). All dogs were treated with antihistamine fexofenadine. Levels of oxidative stress markers (with the exception of skin vitamin E), CADESI-03 and pruritus intensity were determined at the beginning, then every two weeks. Skin vitamin E was determined at the beginning and at the end of the treatment. Significantly higher plasma levels of vitamin E and TAC were observed in the vitamin E group than in the placebo group. CADESI-03 scores determined throughout the treatment in the vitamin E group were significantly lower than in the placebo group. The findings of this study support the supplementation of vitamin E in dogs with atopic dermatitis.

Cats represent a primary source of Microsporum canis infections in humans. Terbinafine hydrochloride (Lamisil) is commonly used in the treatment of microsporosis in humans as its fungicidal action permits short periods of treatment. The aim of the present study was to estimate the efficacy of the drug in cats. Nine cats were experimentally infected with M. canis and treated with terbinafine hydrochloride at a dose of 10-20 mg/kg (once daily, SID; low-dose group, LDG). Another nine cats were similarly infected and treated with 30-40 mg/kg SID (high-dose group, HDG) and a further nine cats were also infected and left untreated (control group, CG). The general condition of the cats was observed daily and their clinical symptoms evaluated weekly. The cats recovery was monitored using the Wood's lamp illumination test and microscopic and fungal culture examinations. The general condition of the cats during the study was good. The cure rates of the LDG were not significantly different from the CG at any period during the treatment. However, the HDG cure rates differed significantly from the other two groups. After 109 days of treatment, when all nine cats of the HDG were healed, seven cats of the LDG and all the cats in the CG were still M. canis-positive. This study shows that dosages of 10-20 mg/kg SID of terbinafine hydrochloride are not sufficient to terminate an experimental M. canis infection in cats within an acceptable period of time. Terbinafine hydrochloride can be used to treat dermatophytosis in cats, but a higher dosage, 30-40 mg/kg SID, should be used to achieve a cure.
