Prednisolone and danazol for treatment of immune-mediated anemia, thrombocytopenia, and ineffective erythroid regeneration in a dog

Abstract

Immune-mediated anemia and thrombocytopenia were diagnosed in an 8-year-old spayed Miniature Schnauzer. The initial CBC indicated poor erythroid regeneration and concurrent leukopenia. The results of a Coombs test and ANA titer were strongly positive. Examination of a bone marrow specimen revealed erythrophagocytosis and a maturation arrest in the RBC series. Treatment with transfusion plus prednisolone and an attenuated androgen (danazol) resulted in stabilization of the PCV and the development of reticulocytosis.
