CME: Addressing needs and improving outcomes in pyruvate kinase deficiency (PKD)

Activity Description / Statement of Need:

In this online, self-learning activity:

Pyruvate kinase (PK) is an enzyme that plays a major role in a metabolic pathway integral to the production of ATP, and a deficiency in the enzyme (PKD) is one of the most common enzyme-related glycolytic defects in a pathway integral to the production of ATP. It is transmitted as an autosomal recessive trait and is caused by mutations in the PKLR gene on chromosome 1, and over one hundred eighty of these mutations have been associated with PKD. While PKD affects approximately five people of European descent per 100,000 (data in other patient populations are lacking), it is one of the more frequent causes of chronic hemolysis. Anemia arising from the condition may range from mild and fully compensated to life-threatening in severity.

Target Audience:

HCPs including: hematology; nurse practitioners, physician assistants, and pharmacists who specialize in hematology; and those with an interest in or may clinically encounter patients with PKD.

Commercial Support Disclosure: This program is supported by an educational grant from Agios Pharmaceuticals. 

This activity is free of charge.
