Itch is defined as an uncomfortable sensation on the skin that causes the desire to scratch. The desire to scratch however, may be induced from a plethora of causes, from some seemingly innocuous environmental triggers, to even include infectious ones. Thus, a pragmatic and systematic approach to a pruritic canine patient with a final end result/diagnosis of canine
atopic dermatitis (CAD) is very important in order that
a correct diagnosis may be made consistently and the quality of life quickly restored to the patient. CAD is defined as a genetically predisposed, inflammatory and pruritic, allergic skin disease with characteristic clinical features, most commonly associated with IgE antibodies to environmental allergens.1 Since the first diagnostic criteria for CAD was published in 1986 by Dr. Willemse, who directly transposed from the human criteria as set forth by Hanifin and Rajka, it set in motion a collective effort by veterinary dermatologist, immunologist
and researchers to further define the disease, refine
its diagnosis and treatment whilst broadening our understanding of this complex, multifactorial disease.2, 3 Approximately 10 years later, Dr. Prélaud and colleagues proposed a new set of five criterias, where fulfilment
of three criterias yielded a sensitivity of 79% and a specificity of 81% for the diagnosis of CAD.4 Most
recently in 2010, Favrot and colleagues proposed a new criteria where a fulfilment of five criteria from the first
set had a sensitivity of 85% and a specificity of 79%.5
An improvement from the previous. This increase in sensitivity could be explained by the added exclusion criteria of an affected ear margins (suspicious of sarcoptic mange) and also an affected dorso-lumbar area (suspicious of flea allergic dermatitis). Thus setting the tone for our approach in a pruritic canine patient where the diagnostic end point is the diagnosis of CAD, which is a clinical diagnosis based on the exclusion of other pruritic disease.
