Comp Haem Intern 1, Diagnosis may be considered on the basis of the clinical features and laboratory findings: Here you find more than 10 standard spring articles.

The natural occurrence of hereditary blood disorders in animals provides a unique opportunity to study the biochemical and molecular pathogenesis of these diseases and to investigate possible therapeutic options Giger et alSewell et al Breed-specific hereditary diseases and genetic screening.

PK is a key regulatory enzyme of glycolysis and two major metabolic abnormalities result from PK deficiency: This was unfortunately done in this case, which emphasizes the importance of classifying the regenerative anemia into hemolytic versus blood loss anemia and reaching a definitive diagnosis.

Mol Med 16, This case report describes the clinical course, laboratory alterations, molecular diagnosis, and management of the first PK-deficient Brazilian WHWT dog, suggesting the potential worldwide distribution of this disorder and that it possibly goes by under-diagnosed.

Briefly, DNA was extracted from nucleated cells deficienca a small aliquot of the EDTA blood and specific primers were used to amplify the region surrounding the known mutation in WHWT with a polymerase chain reaction.

While dogs do not generally have any clinically relevant naturally occurring alloantibodies, they can develop ve against blood groups and a common red cell antigen following transfusion, as seen in this case. Subjects with symptomatic cholelithiasis or cholecystitis may be rescreened once the disorder has been treated and clinical symptoms have resolved.

The dog reported here was found to have this same mutation thereby confirming PK deficiency. In this report, the dog did not show any hepatosplenomegaly, hepatic disease or iron accumulation, but a hepatic biopsy and iron assessment were not carried out.
