[Specific immunotherapy of canine atopy. A prospective clinical study using tyrosine adsorbents].

It is reported about a non-randomized prospective study of the treatment of 17 atopic dogs over a nine-months-period using tyrosine-precipitated vaccines. All dogs were presented because of perennial atopic skin diseases at a practice for internal medicine between 1992 and 1995. The clinical degree of pruritus and dermatitis was controlled before, after three, six, and nine months of immunotherapy individually. After nine months of immunotherapy five dogs showed a reduction of the symptoms for more than 75%, six dogs for more than 50%, six dogs for less than 50%. Eleven (65%) dogs were classified as having been successfully treated, six (35%) showed poor clinical response. Tyrosine-precipitated vaccines were found to be helpful in the treatment of atopic skin diseases of the dog.
