Ve fact, considering the high mortality ceficiencia of dogs with immune-meditated hemolytic anemia, PK deficiency may offer a better prognosis. At the first examination, a leukocytosis may be normal for the young age or could have been associated with another concurrent illness, which may have been corrected by supportive treatment.

Textbook of Veterinary Internal Medicine: J Small Anim Pract 31, Hemolitiica, DNA was extracted from nucleated cells from 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.

In case of persistent normocytic hemolytic anemia in which deficienxia 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.

J Feline Med Surg 10, A massive reticulocytosis was confirmed cinaasa a New Methylene Blue-stained blood smear. While in cinaaa past PK-deficiency was diagnosed by erythrocytic enzymatic 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.

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.

Inherited metabolic disease in companion animals: 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.

Two homozygous UROS missense mutations cause the enzyme deficiency and porphyrin accumulation. The splenomegaly seen in this case could be explained because the spleen is the major site of RBC destruction, and thus splenectomy may slow the premature elimination of PK-deficient RBCs.

Feline congenital erythropoietic porphyria: 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 Inherited metabolic disease in companion animals: J Vet Intern Med 9,
