Biochemical status of blood of dogs with atopic dermatitis in the conditions of private veterinary clinic “Alfa vet” m. Konotop

Metabolic changes in the body of dogs with atopic dermatitis and the causes of its occurrence still remain poorly understood. This study confirms the need for biochemical blood tests for the differential diagnosis of skin diseases in animals. The aim of the research. To identify metabolic changes in dogs with atopic dermatitis. Methods. Serum samples from five ill animals and five intact animals were tested. The diagnosis of the nosological form of skin lesions was established based on the results of anamnesis and clinical manifestations of the disease. Additionally, biochemical studies of the serum of sick animals were performed. Blood of dogs (n=5) was taken from the anterior subcutaneous vein of the forearm or the lateral subcutaneous vein of the tibia into blood tubes. Results. In the study of mineral metabolism, it was found that the concentration of inorganic phosphorus in the serum of sick animals is reduced by only 0.01 mmol/l, but the concentration of total calcium by 10.0 %. The concentration of cholesterol increases 1.3 times and exceeds the reference values by 0.16 mmol/l. In the blood of sick animals, the activity of alanine aminotransferase is significantly reduced by 21.0 % and aspartate aminotransferase – by 20.0 % compared to intact animals. The enzyme gamma-glutamyltransferase probably increases by 1.51 times (P<0.05) in sick dogs, but does not exceed the reference values. Conclusions. It was found that in atopic dermatitis in the serum of dogs decreases the activity of alanine aminotransferase by 21.0 % and aspartate aminotransferase – by 20.0 %, while the activity of gamma-glutamyltransferase increases 1.51 times. The results show the toxic effect of an allergic agent on animals, especially on the liver, which confirms the previous diagnosis – atopic dermatitis.
