title: Persistent thrombocytopenia in a case of equine infectious anemia.
abstract: Persistent thrombocytopenia was detected in a horse with equine infectious anemia (EIA). The thrombocytopenia was considered to be immune-mediated, developing secondary to infection with EIA virus. Epistaxis, petechial hemorrhages, subcutaneous hematomas, and edema resolved after treatment with corticosteroids; however, the owners requested that the mare by euthanatized because of infection with EIA virus. Although clinical signs attributable to immune-mediated thrombocytopenia may resolve with appropriate treatment, horses with immune-mediated thrombocytopenia secondary to EIA have a guarded to grave prognosis, because of the risk of recurrence and transmission of the EIA virus.
