J Small Anim Pract 31, Disease definition Hemolytic anemia due to red cell pyruvate kinase Re deficiency is a metabolic disorder characterized by a variable degree of chronic nonspherocytic hemolytic anemia.

Subjects with hepatitis C may be rescreened after receiving appropriate hepatitis C treatment j. No clinically practical specific treatment has yet been established for PK-deficient animals.

Consecuencias de la deficiencia PK en eritrocito by Sofía Herrera on Prezi

Vet Clin Pathol 35, In veterinary clinics, it is more important to recognize PK deficiency in order to avoid excessive diagnostic procedures for the affected dogs and unnecessary or even harmful treatments with medications such as immunosuppressive agents and iron supplementation. Feline congenital erythropoietic porphyria: The Dog and Its Genome. 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. Usually the dogs that live longer develop severe liver disease with hemosiderosis.


Orphanet: Anemia hemolítica por deficiencia de piruvato quinasa de los glóbulos rojos

Ansmia, a hemolytic anemia caused by an infection, immune-mediated process or toxicity was considered. New York Times bestselling author James Grippando delivers a powerful, nonstop thrill ride ripped from the headlines.

Since this is the first case report of PK-deficiency from Brazil, it will be important to investigate the presence of asymptomatic carriers to avoid the spreading of this disorder Giger Regenerative anemias caused by blood loss or hemolysis. 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.

Clinicians often do not consider hereditary RBC defects, as they are believed to occur rarely. Long-term survival and reversal of iron overload after marrow transplantation in dogs with congenital hemolytic anemia.

Based upon the clinical signs and anemia a transfusion was deemed necessary. Vet Clin Pathol 39, Thus, PK-deficient patients and for that matter any animals with hemolytic anemia should not be supplemented with oral or parenteral iron.


Immune-Mediated Anemias in the Dog. While dogs do not generally have any clinically relevant naturally occurring alloantibodies, they can develop antibodies against blood groups deficeincia a common red cell antigen following transfusion, as seen in this case.

cinaea Leukopenia and thrombocytopenia was also noted and could be explained by the possible myelofibrosis, common in dogs with this disorder permission for a bone marrow biopsy was not received.

The diagnosis of PK deficiency was suspected in the Cinada described here, because of the breed, young age of anemia, persistence of the highly regenerative anemia heolitica osteosclerosis and was confirmed by a simple DNA mutation test. It should be noted that the fall in PCV observed in the last month of life was associated with a diminished bone marrow response, as shown by both the lower absolute reticulocyte count and reticulocyte production index.


In this case report, we conclude that the prognosis would have been better if the etiology of severe anemia was identified soon.

While PK-deficient cats and humans may also develop bilirubin calculi and gall bladder blockade, this has not been reported in PK-deficient dogs. J Pediatr In humans, splenectomy can reduce the degree of hemolysis in some patients, but PK-deficient Basenji piruavto did not improve clinically after surgery. 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.
