Efficacy of hydrolyzed soy dog food and homemade food with original protein in the control of food-induced atopic dermatitis in dogs

ABSTRACT: Trophoallergens are specific components of food or its ingredients, able to precipitate the atopic eczema at 19.6% to 30% of the dogs with atopic dermatitis (AD). This study evaluated the efficacy of hydrolyzed soy dog food and homemade food with unusual protein in the control of chronic pruritus in dogs with AD. For this, twenty-eight dogs with AD were selected. AD diagnosis was based on Favrot’s criteria. The animals were separated in two groups; one group consumed hydrolyzed soy dog food while the other group consumed homemade food with protein sources and original carbohydrates. They were evaluated every two weeks by the Rybnicek and CADLI scale over 60 days. Animals in the group that consumed hydrolyzed soy dog food presented a reduced score of pruritus (Rybnicek scale) on days +15, +30, +45 and +60 (P0.05) in 60 days of treatment. When evaluated by the Canine Atopic Dermatitis Lesion Index (CADLI), dogs treated with soy hydrolyzed dog food had a partial improvement on days +45 (P0.05) in 60 days of treatment. In conclusion, soy hydrolyzed dog food has proved effective to partially control clinical signs of food-induced atopic dermatitis; however, it is not effective for the complete control of the disease

Evaluation of the concentration of allergens from mites in fur and households dust of dogs with atopic dermatitis

ABSTRACT: This study evaluated the concentration of Der p 1, Der f 1 and Blo t 5 in the fur and households of 20 dogs with atopic dermatitis (AD) and 20 healthy dogs. The diagnosis of AD was clinical based on Favrot’s criteria. Dust samples were collected with a domestic vacuum cleaner. For each site, 1m2 was vacuumed for 2 min. The samples were collected in separate filters, transferred into plastic containers, sealed and kept frozen until ELISA analysis. In the fur of atopic dogs the average concentration of Der p 1 was 0.25μg/g compared to 0.03μg/g in healthy dogs. In households with atopic dogs the highest concentrations of Der p 1 were found in carpets (2.18μg/g), followed by couches (1.53μg/g), beds (1.14μg/g), dogs’ bed linen (0.64μg/g) and floors (0.14μg/g). The concentrations of Der p 1 on carpets, couches and beds were significantly higher than in atopic dogs’ fur (p0.05). The concentrations of Der p 1, Der f 1 and Blo t 5 were equivalent in atopic and non-atopic dog’s households. Among the allergens studied, Der p 1 was the most commonly found, predominantly in carpets and couches

Eficácia da ciclosporina no controle da dermatite atópica em cães

RESUMO: A dermatite atópica é uma dermatopatia inflamatória, pruriginosa, crônica, de origem genética, resultante da perda da função de barreira física da pele e da hiperreatividade à alérgenos ambientais, trofoalérgenos, alérgenos microbianos e a irritantes primários. Este estudo avaliou a eficácia da ciclosporina no controle do prurido e das lesões associadas à dermatite atópica em cães. Selecionaram-se 24 cães com diagnóstico de dermatite atópica baseados nos critérios de Favrot et al. (2010), os quais foram divididos em dois grupos de 12 cães, onde o Grupo 1, recebeu ciclosporina (5mg/kg/vo/24h), e o Grupo 2, foi tratado com prednisona (0,5mg/kg/vo/24h) em doses decrescentes, ambos por 60 dias. Os animais foram continuamente avaliados, e seus escores sintomato-lesionais, baseados na escala de CADESI-03, estabelecidos nos dias 0, 30 e 60. Em adição, os escores de prurido de cada animal, baseado nos critérios de Rybnicek, foram semanalmente avaliados, do dia 0 ao 63. Todos os dados coletados foram analisados pelo teste não paramétrico de Kruskal-Wallis, seguido do teste de Dunn´s e para as análises entre os grupos foi utilizado o teste t, considerado o nível de significância mínimo de 5%. A ciclosporina teve uma eficácia similar, no controle lesional, ao grupo que recebeu prednisona no dia (+30) (p0,05). Apesar da ciclosporina ter sido menos eficaz no controle do prurido, este se manteve em níveis aceitáveis, e seu uso contínuo não foi associado a efeitos colaterais relevantes

Síndrome do gucagonoma em cão Glucagonoma syndrome in a dog

O eritema necrolítico migratório é rara dermatose caracterizada por lesões erodo-ulcerativas e crostosas em áreas intertriginosas, junções mucocutâneas, superfícies articulares e de apoio crônico, que tem sido descrita em seres humanos, cães, gatos e rinocerontes. Sua etiologia tem sido relacionada a neoplasias pancreáticas, mormente das células alfa produtoras de glucagon, e a graves doenças do parênquima hepático ou gastroentérico. Relata-se o caso de um cão com necrose epidérmica metabólica secundária a glucagonoma, que apresenta fortes similaridades com a síndrome do glucagonoma em humanos.<br>Nail fold Necrolytic migratory erythema is a rare skin dermatosis characterized by erosive and crusted lesions in intertriginous areas, mucocutaneous junctions, articular areas and pressure points. It has been described in humans, dogs, cats and rhinoceros. The cause of this condition is related to glucagon-secreting alpha cell tumor of the pancreas, severe hepatopathy or gastrointestinal disease. Here, we report the case of a dog with necrolytic migratory erythema due to glucagonoma, closely resembling the glucagonoma syndrome observed in humans
