Kraftig anemi hos tax

Sammanfattning: The Clinical Pathology Laboratory at SLU in Uppsala has analysed several blood samples from Dachshunds with severe anemia. As there are no previous studies on this topic, a study was performed to evaluate if Dachshunds are more prone to severe anemia compared with other breeds. In addition, a retrospective case study on Dachshunds with severe anemia was done to search for common risk factors or diseases. Hemoglobin values in samples from 1272 Dachshunds and 2269 German Shepherds analyzed from September 1994 to October 2007 were used to compare the frequency of severe anemia in Dachshund and German shepherd. The samples were identified by laboratory information system. It was more common with severe anemia in Dachshunds compared with German Shepard dogs (G-test, p< 0,0001). In the retrospective case study fifteen Dachshunds with severe anemia (Hb < 63,5g/L or EVF < 19 %) were included. The records were studied with concern to gender, age, anamnestic data, symptoms, laboratory results, treatment and diagnosis. The average age of the Dachshunds was 7,5 years. Nine of the dogs were female and six were male. Eight of the Dachshunds had regenerative anemia and seven had non-regenerative anemia. The span of diseases or conditions causing severe anemia in the individual cases was very wide. The diseases found in the fifteen Dachshunds was immunomediated hemolytic anemia (3 cases), hemolysis caused by snake bites, hemorrhage caused by whelping, chronic renal failure, neoplastic conditions causing bone marrow suppression (4 cases) and side effects from cytotoxic drugs. Five of the dogs in the study survived, one died and nine were euthanized. In conclusion, an increased frequency of Dachshunds with severe anemia in comparison to German shepherds was observed. No specific risk factors or diseases could be identified in this study.
