The present study aims at the identification of undesirable effects of ribavirin, predinisone and DMSO in dogs naturally infected by canine distemper virus. The research analyzed 60 dogs with clinical neurological signs and 10 days of evolution. The animals were hospitalized for the appropriate support treatment; were daily observed, and complete blood cells count, biochemical analysis, and urine exam type I were conducted. Groups 1 and 2 were treated with ribavirin and its combination with DMSO; Groups 3 and 4 treated with prednisone and DMSO, Group 5 treated with ribavirin and prednisone, while Group 6 with ribavirin, prednisone and DMSO. Before the treatment, animals were anesthetized for the cerebrospinal fluid, bone marrow and blood samples collection for the diagnosis based on RT-PCR. The negative samples were analyzed using the hn-PCR technique. All the animals presented positive results in at least one of the 2 tests. The adverse result of ribavirin and its association with prednisone was characterized by haemolytic anemia, confirmed by the evaluation of bilirrubin occurrence only in the urine of dogs treated with ribavirin. |
