Resumo
Background: The IMHA is a common cause of anemia in dogs and characterized by direct destruction or phagocytosis of erythrocytes opsonized by IgG, IgM and/or complement. The diagnosis is based on the identification of erythrocytes destruction in the presence of anti-erythrocyte antibodies, producing spherocytes, auto-agglutination, Coombs test or flow cytometry test positive, in addition to anemia and clinical signs of hemolysis. The renal biochemical profile and urinalysis may reveal important changes due to the severity of the kidney demage. The aim of this study were to evaluate the incidence of hematological and renal abnormalities, and the prevalence of immunoglobulins classes involved in IMHA.Materials, Methods & Results: In a total of 87 anemic dogs were selected and tested by Coombs test, flow cytometry (FC), and auto-agglutination, along with CBC, reticulocyte count, renal profile (ureia and creatinine), hemoparasite search in peripheral blood smears, and Ehrlichia sp. and leptospirosis tests. The results were analyzed by t test or Mann-Whitney with 5% of significance. Therefore, 61 dogs (70.11%) were positive for IMHA by FC, 31 (35.63%) by Coombs test, and 24 (27.58%) by auto-agglutination. There was not a predominance of IgG or IgM involvement. The hematological and clinical changes in dogs with IMHA included macrocytic, hypochromic regenerative anemia, and r
