Critically appraised topic on adverse food reactions of companion animals (1): duration of elimination diets

Thierry Olivry et al. BMC Vet Res. .

Abstract

Background: Restrictive (i.e. elimination)-provocation dietary trials remain the standard of care to diagnose cutaneous adverse food reactions (CAFRs) in dogs and cats. There is currently no consensus on the duration of elimination diet trials that would permit the highest sensitivity of diagnosis of CAFR in companion animals.

Results: The search for, and review and analysis of the best evidence available as of December 14, 2014 suggests that, by 5 weeks in dogs and 6 weeks in cats after starting an elimination diet, more than 80 % of patients had achieved a remission of clinical signs of CAFR. Increasing the diet trial duration to 8 weeks leads to a complete remission in more than 90 % of dogs and cats with CAFR.

Conclusions: For diagnosing CAFRs in more than 90 % of dogs and cats, elimination diet trials should last at least 8 weeks.
