“…Six more relevant citations were identified in the bibliography of articles found with the electronic search [ 18 – 22 ], and three sources were abstracts of recent conference proceedings [ 23 – 25 ]. Offending allergens were reported in case reports [ 12 , 14 , 18 , 22 , 26 ] or case series of dogs and cats with clinical evidence of adverse food reaction [ 1 – 5 , 7 , 10 , 13 , 16 , 19 , 25 , 27 ], in studies evaluating diagnostic techniques for adverse food reactions [ 5 , 8 , 9 , 11 , 17 , 23 , 24 ] or (rarely) in studies evaluating reaction patterns such as vasculitis or symmetrical lupoid onychitis with multiple causes [ 20 , 21 ]. A positive rechallenge was considered the only solid evidence for identifying an offending allergen.…”

Background: To diagnose cutaneous adverse food reactions (CAFRs) in dogs and cats, dietary restriction-provocation trials are performed. Knowing the most common offending food allergens for these species would help determining the order of food challenges to optimize the time to diagnosis. Results: The search for, and review and analysis of the best evidence available as of January 16, 2015 suggests that the most likely food allergens contributing to canine CAFRs are beef, dairy products, chicken, and wheat. The most common food allergens in cats are beef, fish and chicken. Conclusions: In dogs and cats, after a period of dietary restriction leading to the complete remission of clinical signs, food challenges to diagnose CAFR should begin with beef and dairy products, the most commonly recognized food allergens in these two species.

“…A hipersensibilidade alimentar foi observada em menor percentual por Souza et al (2009) e Cardoso et al 2011que encontrou 11,11%. Já Salzo & Larsson (2009) observaram a prevalência mais próxima do encontrado nesse estudo com 17,1%. O sinal clínico mais evidente nos seis casos foi o prurido associado a outros sinais clínicos.…”

“…O sinal clínico mais evidente nos seis casos foi o prurido associado a outros sinais clínicos. As lesões macroscópicas e a distribuição anatômica foram semelhantes às descritas por Medleau & Hnilica (2009), Salzo & Larsson (2009) e Rondelli et al (2015).…”

“…No presente estudo a associação da corticoterapia e a dieta de substituição demonstram ser uma ferramenta tanto de diagnóstico quanto terapêutica, corroborando com os estudos de Salzo & Larsson (2009) e Rondelli et al (2015). Houve maior ocorrência de HA em cães sem raça definida, diferente do observado por Salzo & Larsson (2009), que verificou maior frequência em cães da raça Poodle. Neste estudo as fêmeas foram mais acometidas, diferente do observado que obteve maior frequência em cães machos (Salzo & Larsson 2009.…”

“…Neste estudo as fêmeas foram mais acometidas, diferente do observado que obteve maior frequência em cães machos (Salzo & Larsson 2009. Os animais acometidos tinham idade superior a dois anos, o que também foi descrito na literatura (Salzo & Larsson 2009), porém de acordo com White (2003), a hipersensibilidade alimentar deve sempre constar do diagnóstico diferencial de prurido em cães jovens com menos de um ano.…”

RESUMO: Descrevem-se as características clínicas e histopatológicas da dermatite alérgica diagnosticada em cães da região metropolitana de João Pessoa, Paraíba. Durante o período de setembro de 2014 a setembro de 2015, um total de 90 cães com lesões cutâneas. Desses 24 apresentaram alterações compatíveis com dermatite alérgica, sendo 12 machos e 12 fêmeas. A dermatite atópica (DA) foi a mais frequente, afetando 58,33% (14/24) dos cães, seguido por dermatite por hipersensibilidade alimentar (HA) 25% (6/24), dermatite de contato alérgica (DAC) com 8,33% (2/24) dos casos, dermatite alérgica por picada de pulgas (DAPP) com um caso e a hipersensibilidade a medicamento (farmacodermia) também um caso, que representou 4,17% respectivamente. As lesões macroscópicas incluíram hipotricose, hiperpigmentação, comedões, eritema, alopecia, xerose, erosões, úlceras e exsudato, anatomicamente distribuídas na face, cabeça, pescoço, toracolombar, lombossacra, flanco, membros e abdome. As lesões microscópicas mais frequentes foram hiperceratose, acantose, espongiose e exocitose de linfócitos na epiderme. Na derme superficial foi observada perivasculite, perianexite e em alguns casos de incontinência pigmentar, edema, dilatação de vasos sanguíneos, linfáticos e glândulas sudoríparas. O exame histopatológico associado com a história clínica, exame clínico e pele são ferramentas importantes para o diagnóstico de dermatite alérgica em cães, bem como medidas terapêuticas associadas.

BackgroundThe prevalence of cutaneous adverse food reactions (CAFRs) in dogs and cats is not precisely known. This imprecision is likely due to the various populations that had been studied. Our objectives were to systematically review the literature to determine the prevalence of CAFRs among dogs and cats with pruritus and skin diseases.ResultsWe searched two databases for pertinent references on August 18, 2016. Among 490 and 220 articles respectively found in the Web of Science (Science Citation Index Expanded) and CAB Abstract databases, we selected 22 and nine articles that reported data usable for CAFR prevalence determination in dogs and cats, respectively. The prevalence of CAFR in dogs and cats was found to vary depending upon the type of diagnoses made. Among dogs presented to their veterinarian for any diagnosis, the prevalence was 1 to 2% and among those with skin diseases, it ranged between 0 and 24%. The range of CAFR prevalence was similar in dogs with pruritus (9 to 40%), those with any type of allergic skin disease (8 to 62%) and in dogs diagnosed with atopic dermatitis (9 to 50%). In cats presented to a university hospital, the prevalence of CAFR was less than 1% (0.2%), while it was fairly homogeneous in cats with skin diseases (range: 3 to 6%), but higher in cats with pruritus (12 to 21%) than in cats with allergic skin disease (5 to 13%).ConclusionsAmong dogs and cats with pruritus and those suspected of allergic skin disease, the prevalence of CAFR is high enough to justify this syndrome to be ruled-out with a restriction (elimination)-provocation dietary trial. This must especially be considered in companion animals with nonseasonal pruritus or signs of allergic dermatitis.Electronic supplementary materialThe online version of this article (doi:10.1186/s12917-017-0973-z) contains supplementary material, which is available to authorized users.
