The pyruvate kinase deficiency in cats is a hereditary hemolytic anemia, which is being passed down from parents to their offspring. This topic reviews the pathogenesis, clinical presentation, diagnosis, and treatment of PK deficiency. Looks like you’ve clipped this slide to already. Open in figure viewer PowerPoint. Pregnancy complicated by pyruvate kinase deficiency is rare; there are only 8 reported cases in the literature. Deficient reticulocytes with limited anaerobic glycolytic capability may also be incapable of effective oxidative phosphorylation in the acidic, hypoglycemic splenic environment (see Pyruvate Kinase Deficiency ), thereby leading to metabolic failure and hemolysis. These enzymes are part of a group of three enzymes called the pyruvate dehydrogenase complex. erythrocytic pyruvate kinase deficiency: haematological implications 1. a presentation on erythrocytic pyruvate kinase deficiency: haematological implications by sct.

Pyruvate kinase deficiency, one of the most common enzymatic defects of the erythrocyte, manifests clinically as a hemolytic anemia that can range from a mildly compensated anemia to severe anemia of childhood. Pets with pyruvate kinase deficiency have chronic anemia, therefore, they are able to compensate for their anemia and tend to tolerate it better than pets who acutely become anemic.
