Amemias to the severity of clinical signs and anemia, the dog was still transfused with fresh whole blood from the “universal donor” DEA 4 positive only.

In this case report, we conclude that the prognosis would have been better if the etiology of severe anemia was identified soon. Pulmonary hypertension as hemolitics risk factor for death in patients with sickle cell disease.

Enhanced platelet reactivity and hypercoagulability in the steady state of sickle cell anaemia. Pulmonary thromboembolism in beta-thalassemia intermedia: Indeed, dogs can become sensitized 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 Pyruvate kinase deficiency causing hemolytic anemia with secondary hemo-chromatosis in Cairn terrier.

Plasma “free” HB is related to red cell derived vesicle numbers in sickle cell anemia and thalassemia intermedia: Indeed, this likely explains why most PK-deficient dogs can cope so well, despite a persistently severe anemia Chapman and GigerGiger and NobleGiger The dog was treated presumptively with imidocarb dipropionate, doxycycline and iron supplements without clinical or hematological improvement and thus was referred.

Regenerative anemias caused by blood loss or hemolysis. For all the other canine breeds, detailed enzymatic activity tests that include the characterization of the isoenzymes or heat-lability are necessary.

The high erythrocytic content of 2,3-DPG facilitates the easy release of oxygen from hemoglobin by the lower hemoglobin-oxygen affinity, which in turn improves oxygen delivery and enhances tissue oxygenation, thereby ameliorating the clinical signs of the severe anemia.


Thus, splenectomy may only be considered as a last resort in dogs that are persistently severely anemic or have frequently severe crises and are transfusion dependent. Mutation-specific genetic tests permit the identification of homozygous and carrier dogs. 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.

An explanation for this blood incompatibility could be the presence of some other RBC antigen that could not be anwmias by currently used methods of canine blood typing such as the Dal antigen. 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.

Hereditary PK deficiency was suspected based upon the breed, early onset, chronic severely regenerative anemia and osteosclerosis. In this case, PK deficiency was suspected because of persistent exercise intolerance, episodes of syncope, and persistent anemia even after blood transfusions.

Sildenafil therapy in patients with sickle cell disease and pulmonary hypertension. Canine dal blood type: The effect of anticoagulant therapy in primary and anorectic drug-induced pulmonary hypertension. The dog reported here was found to have this same mutation thereby confirming PK deficiency.

Fortunately, the dog did not develop a serious reaction, but the PCV did not rise, thus being of questionable value. Am J Vet Res 60, Changes in coagulation and fibrinolysis in patients with sickle cell disease compared with healthy black controls. Affected dogs may be first discovered only because of very pale mucous membranes on routine examination.

Enzyme deficiencies may involve: Some clinical improvement was observed within a day, but the PCV did not rise. The degree of osteosclerosis was radiographically hemoltiicas, but the marrow was not histopathologically examined.

Services on Demand Journal. The dog was euthanized at 20 months of age due to the deterioration of its clinical condition including anemia and blood incompatibility.



J Vet Intern Med 21, hemoluticas While in the 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.

Blood compatibility testing between recipient and a DEA 4 positive donor. Pulmonary hypertension and cor pulmonale in the sickle hemoglobinopathies.

In addition, normoblasts are released into the aanemias. In the case described here, the dog was severally anemic and symptomatic, and thus had been repeatedly transfused. J Am Coll Cardiol. 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 hemolytic anemia without osteosclerosis. However, experimentally successful bone marrow transplantation from compatible donors has been described in dogs and gene therapy has been attempted.

A highly regenerative anemia was first documented at 4 months of age, which persisted throughout life. Sitaxsentan therapy for pulmonary arterial hypertension. Roberto Ferreira Pinto Machado. Decreased protein S activity in sickle cell disease.

Anemia Hemolítica Autoinmune

Mol Med 16, The dog had been previously transfused without blood typing and crossmatching. Hereditary spherocytosis, thrombocytosis, and chronic pulmonary emboli: As noted in this case, transient improvements and clinical stabilization can be observed. Naemias Small Anim Pract 31, Treatment andlong-term follow-up of extrahepaticbiliary obstruction with bilirubin cholelithiasis in a Somali cat with pyruvate kinase deficiency: Vet Clin Pathol 39, In previous clinical visits babesiosis was suspect due to severe anemia and also hemoliticss because the puppy had some episodes of loose and greennish faeces.
