Moreover, in certain breeds, PK deficiency, just cinass other hereditary disorders and genetic predispositions to disease, deficienci occur commonly due to the breeding of carrier animals HarveySewell et alGiger 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.

Inherited erythrocyte pyruvate kinase deficiency in a Beagle. In previous clinical visits babesiosis was suspect due to severe anemia and also giardiasis because the puppy had some episodes of loose and greennish faeces.

PK deficiency is a hereditary disorder which has been studied by hematologists and geneticists for decades, in df attempt to better understand its disease process and prevalence, and in order to reach more reliable diagnosis and develop better therapeutics for affected patients.

Clinicians often do not consider hereditary RBC defects, as they are believed to occur rarely.

Mutation-specific genetic tests permit the identification of homozygous and carrier dogs. Have a prior bone marrow or stem cell transplant 8.

Its plasma was incompatible against 10 donors in the major crossmatch autocontrols were negativesincluding a “universal donor” only DEA 4 positive and two relatives of the patient figure 2. Radiographs from this WHWT terrier described here revealed only a mildly decreased bone radiopacity of the pelvic bones, probably due to the young age of the animal Chapman and GigerHarvey et alVan Geffen et al The treatment is mostly supportive and any other illnesses, stress or excessive exercise should be avoided.


However, the presentation of chronic, severe, highly regenerative, and Coomb’s negative hemolytic anemia in a young dog which is unresponsive to treatment should raise suspicion. Indeed, dogs can become deficiejcia to other RBC antigens than one can test for and thus be incompatible to even the “universal donor” Callan et alBlais et alKessler et al Cats exhibit intermittent lethargy, pale mucous membranes and have intermittently mild to moderately severe anemia which may be complicated by bilirubin bile calculi GigerHarvey et alKohn and FumiVan Geffen anemiz alGiger Based upon the clinical signs and anemia a transfusion was deemed necessary.

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


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. Indeed, this likely explains why most PK-deficient dogs can cope so well, despite a persistently severe anemia Chapman and GigerGiger and NobleGiger Thus, deficiencja against DEA 1.

Molecular basis of erythrocyte pyruvate kinase R-PK deficiency in cats. In this case, PK deficiency was suspected because of persistent exercise intolerance, episodes of syncope, and persistent anemia even after blood transfusions.

These studies have and will bring benefits for humans and for animals. Usually piruvatl dogs that live longer develop severe liver disease with hemosiderosis. Breed-specific hereditary diseases and genetic screening. On blood smear evaluation anisocytosis, marked polychromasia, and normoblastosis were present. Subjects with hepatitis C may be rescreened after receiving appropriate hepatitis C treatment j. A massive reticulocytosis was confirmed on a New Methylene Blue-stained blood smear.

Molecular basis of erythrocyte pyruvate kinase R-PK deficiency in cats. Prior cholecystectomy is not exclusionary.


Thus, a hemolytic anemia caused by an infection, immune-mediated process or toxicity was considered. PDFCreator, free and safe download. Vet Clin Pathol 20, On blood smear evaluation hemolirica, marked polychromasia, and normoblastosis were present.

Piruvato quinase

Summary and related texts. Usually the dogs that live longer develop severe liver disease with hemosiderosis. In fact, considering the high mortality rate of dogs with immune-meditated hemolytic anemia, PK deficiency may offer a better prognosis. In the case described here, the dog was severally anemic and symptomatic, and thus had been repeatedly transfused. Blood compatibility testing between recipient and a DEA 4 positive donor.

Hemolitiac J Dog erythrocyte antigens 1. Unfortunately, no information of the breeder or related dogs was available to further trace this dog’s ancestors and to identify related potential carrier or affected dogs.

Inherited erythrocyte pyruvate kinase deficiency in the West Highland White terrier. New York Times bestselling author James Grippando delivers a powerful, nonstop thrill ride ripped from the headlines. Transfusions may be necessary, but testing for blood compatibility is important to ensure the safety and efficacy of transfusions. In order to prevent the further spread of this and other hereditary diseases, it is essential to recognize not only the affected animals, he,olitica also the carriers that can transmit the mutant allele to their offspring.

Anemia hemolítica por deficit de piruvato cinasa by Doris Cruz on Prezi

In contrast to PK-deficient dogs in which the anemia is typically first recognized in young animals, PK deficient cats have intermittent anemia and are often not diagnosed until they are of advanced age. J Small Anim Pract 49, xe As noted in this case, transient improvements and clinical stabilization can be observed. Low dose glucocorticosteroid therapy may reduce RBC destruction and thereby ameliorate anemia. Vet Clin Pathol 35,
