What is a PK level?

What is a PK level?

The pyruvate kinase test measures the level of the enzyme pyruvate kinase in the blood. Pyruvate kinase is an enzyme found in red blood cells. It helps change sugar in the blood (glucose) to energy when oxygen levels are low.

What is PK deficiency in Bengal cats?

Pyruvate kinase deficiency in cats is an inherited hemolytic anemia that is passed down from parents to offspring. An affected feline has an absence of the regulatory enzyme, pyruvate kinase, which is responsible for the metabolism of energy used to create more red blood cells.

What is pyruvate kinase deficiency cats?

Erythrocyte pyruvate kinase deficiency (PK deficiency) is an inherited hemolytic anemia that has been documented in the Abyssinian and Somali breeds as well as random bred domestic shorthair cats. The disease results from mutations in PKLR, the gene encoding the regulatory glycolytic enzyme pyruvate kinase (PK).

How do you treat pyruvate kinase deficiency in cats?

Bone marrow transplantation is the only available treatment for PK deficient cats. However, this treatment is expensive and potentially life-threatening.

How is PK deficiency diagnosed?

For the specific diagnosis of PK deficiency, further blood tests to measure pyruvate kinase enzyme activity may be necessary. Your doctor will take a blood sample to send to a specialized laboratory to ensure the accuracy of the test. Most people with PK deficiency have 5–25% of the normal enzyme activity.

Is pyruvate kinase inherited?

Red blood cells travel throughout the body delivering oxygen to the tissues. Healthy red blood cells last approximately 120 days. PKD is caused by alterations (mutations) in the PKLR gene, which lead to a deficiency of the enzyme pyruvate kinase. These genetic alterations are inherited in an autosomal recessive manner.

How much is a HCM test for cats?

The initial workup for a cat with HCM typically costs approximately $500-$1,000.

Is pyruvate kinase deficiency inherited?

Pyruvate kinase deficiency is inherited in an autosomal recessive fashion, which means that a child must inherit a gene with a disease-causing mutation from both parents to develop the disorder. The gene that causes pyruvate kinase deficiency is called the PKLR gene that is located on chromosome 1q21.

Is pyruvate kinase deficiency fatal?

In people with pyruvate kinase deficiency, hemolytic anemia and associated complications may range from mild to severe. Some affected individuals have few or no symptoms. Severe cases can be life-threatening in infancy, and such affected individuals may require regular blood transfusions to survive.

What happens when pyruvate kinase is blocked?

Pyruvate kinase enzyme breaks down a chemical compound called adenosine triphosphate (ATP). Because this enzyme is deficient, there is a lack of ATP. This leads to dehydration of red blood cells and abnormal red cell shapes. The altered red blood cell has a shortened lifespan leading to hemolytic anemia.
