Hemolytic anemia due to red cell pyruvate kinase (PK) deficiency is a metabolic disorder characterized by a variable degree of chronic nonspherocytic hemolytic . La deficiencia de piruvato cinasa es una causa rara de anemia hemolítica. Durante el embarazo, se ha tratado casos graves de esta deficiencia con.

Hemolitics 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 In fact, considering the high mortality rate of dogs with immune-meditated hemolytic anemia, PK deficiency may offer a better prognosis.
In order to assure a safe transfusion, compatibility testing was performed.
Low dose glucocorticosteroid therapy may reduce RBC destruction and thereby ameliorate anemia. J Vet Intern Med 9, Due to the postnatal development of the RBC metabolism, the clinical signs of PK deficiency in dogs are not detected until approximately 4 months of age, as seen in this puppy.
There was no evidence of blood loss anemia, and fecal examinations for intestinal parasites were negative. Diseases of Dog and Cat. It is important that hereditary RBC defects, such as PK deficiency, are being considered in cases of hemolytic anemias.

Hum Mol Genet 19, Moreover, in certain breeds, PK deficiency, just like other hereditary disorders and genetic predispositions to disease, may occur commonly due to the breeding of carrier animals HarveySewell et alGiger Biochemical and molecular genetic tests have been developed for many diseases; however, their application as diagnostic tools for companion animals is still limited.
The patient of this report was too debilitated and could not be effectively transfused because of a broad blood incompatibility to prepare the dog safely for this the surgical intervention. Prognosis Prognosis is variable depending on the severity of the anemia, but as in other chronic xinasa disorders, gallstones and iron overload may develop, requiring appropriate treatment.
Have a diagnosis of any other congenital or acquired blood disorder or any other hemolytic process, except mild allo-immunization, as a consequence of transfusion therapy i. Feline acute intermittent porphyria: J Vet Intern Med 21, ipruvato Dogs with PK deficiency often have normal white blood cell counts.
In humans, splenectomy can reduce anemiaa degree of hemolysis in some patients, but PK-deficient Basenji dogs did not improve clinically after surgery. J Pediatr In veterinary clinics, it is more important to recognize PK deficiency in order to avoid excessive diagnostic procedures anrmia the affected dogs and unnecessary or even harmful treatments with medications such as immunosuppressive agents and iron supplementation.
Thus, PK-deficient patients and for that matter any animals with hemolytic anemia should not be supplemented with oral or parenteral iron.

Treatment andlong-term follow-up of extrahepaticbiliary obstruction snemia bilirubin cholelithiasis in a Somali cat with pyruvate kinase deficiency: Transfusions may be necessary, but testing for blood compatibility is important to ensure pituvato safety and efficacy of transfusions.
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 The approach should be fast so that we can offer a better survival for these patients. 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.
Subjects with symptomatic cholelithiasis or cholecystitis may be rescreened once the disorder has been treated and clinical symptoms have resolved. Inherited erythrocyte pyruvate kinase deficiency in the West Highland White terrier.
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. The dog was found to have persistently profound pallor, a highly regenerative hemolytic anemia and osteosclerosis.
Anemia hemolítica por deficit de piruvato cinasa by Doris Cruz on Prezi
Determination of erythrocyte pyruvate kinase deficiency in Basenjis with chronic abemia anemia. As noted in this case, transient improvements and clinical stabilization can be observed. In dogs, PK deficiency causes a severe chronic and highly regenerative hemolytic anemia with progressive osteosclerosis, while in cats it is characterized by an intermittent ds anemia without osteosclerosis. Hereditary PK deficiency was suspected based upon the breed, early onset, chronic severely regenerative anemia and osteosclerosis.
The Dog and Its Genome. While in the past PK-deficiency was diagnosed by erythrocytic dw activity test, assessment of oxygenhemoglobin dissociation curve, and level of intermediates of the glycolytic pathway, such as 2,3-DPG, a definitive diagnosis in this case was established simply with the PCR mutation-specific test.
In case of persistent normocytic hemolytic anemia in which hemoglobin abnormalities and antiglobulin reactions have been excluded, spherocytes are absent, and osmotic fragility is normal, the diagnosis of hereditary nonspherocytic hemolytic anemia should be considered. However, the anemia did not improve, and the animal’s overall condition deteriorated to cinawa point where the owners elected euthanasia.
The latter should be based deficiencai the patient’s ability to tolerate the anemia. Inherited metabolic disease in companion animals: Hereditary Erythrocyte Enzyme Abnormalities.
