InfancyNeonatal ICD 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.

As noted in this case, transient improvements and clinical stabilization can be observed. Based upon the clinical signs and anemia a transfusion was deemed necessary.

Biochemical and molecular genetic tests have been developed for many diseases; however, their application as diagnostic tools for companion animals is still limited. Molecular basis of erythrocyte pyruvate kinase R-PK deficiency in cats. Hemoitica J Feline congenital erythropoietic porphyria: In addition, normoblasts are released into the circulation. Hereditary Erythrocyte Enzyme Abnormalities.

In this case, the patient could be negative for Dal or another antigen.

Specialised Social Services Eurordis directory. Hum Mol Genet 19, The dog was euthanized at 20 months of age due to the deterioration of its clinical condition including anemia and blood incompatibility. The documents contained in this web site are presented for information purposes only. The diagnosis of PK deficiency was suspected in the WHWT described here, because of the breed, young age of anemia, persistence of the highly regenerative anemia and osteosclerosis and was confirmed by a simple DNA mutation test.

The treatment is mostly supportive and any other illnesses, stress gemolitica excessive exercise should be avoided. J Vet Intern Med 9, Enzyme deficiencies may involve: Regenerative anemias caused by blood loss or hemolysis.

Subjects with hepatitis C may be rescreened after receiving appropriate hepatitis C treatment j.

An explanation for this blood incompatibility could be the presence of some other RBC antigen that could not be identified by currently used methods of canine blood typing such as the Dal antigen. Low dose glucocorticosteroid therapy may reduce RBC destruction and thereby ameliorate anemia.


Piruvato quinase

The dog reported here was found to have this same mutation thereby confirming PK deficiency. Feline acute intermittent porphyria: Different causative PK mutations have been identified in different breeds such as Basenjis, Beagles, WHWT, while within a breed all affected dogs have the same mutation. Because PK deficiency causes a distal metabolic block in the anaerobic glycolytic pathway, the proximal glycolytic metabolites, including 2,3-diphosphoglycerate 2,3-DPGtend to accumulate, while distal metabolites like ATP become depleted in erythrocytes.

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 piryvato Giger et alSewell et al The dog was found to have persistently profound pallor, a highly regenerative hemolytic anemia and osteosclerosis. Dogs with PK deficiency often have normal white blood cell counts.
