Study questions how allergy tests should be used in canine EBP

Dogs with eosinophilic bronchopneumopathy, or EBP, were more likely than healthy controls to have positive intradermal allergy test reactions in a new prospective case-control study published in Frontiers in Veterinary Science, but serum allergen-specific IgE results did not differ between groups. The study included 21 dogs with EBP and 22 healthy dogs, used 41 allergens for intradermal testing and 23 allergens for serum IgE testing, and found only minimal agreement between the two methods. The authors concluded that both tests should be interpreted cautiously and only in the context of the full clinical picture. (frontiersin.org)

Why it matters: For veterinary professionals, the findings add nuance to a long-running question about whether allergic sensitization testing can help explain or manage canine EBP. The signal in intradermal testing supports the idea that hypersensitivity may play a role in at least some dogs, but the similar serum IgE results in healthy controls and the poor concordance between tests argue against overinterpreting a positive result. That fits with broader clinical guidance that the benefit of allergy testing in canine eosinophilic bronchopneumopathy hasn’t been clearly documented, even though hypersensitivity remains a suspected contributor.

What to watch: Watch for follow-up studies linking test results to treatment response, especially whether intradermal findings can meaningfully guide immunotherapy or long-term management in dogs with EBP. (frontiersin.org)
