    ### Instruction:
    What are the treatments for Pyruvate kinase deficiency ?
    ### Response:
    How might pyruvate kinase deficiency be treated? Mild cases require no treatment. People with severe anemia may need blood transfusions.  In newborns with dangerous levels of jaundice, a health care provider may recommend an exchange transfusion. Surgical removal of the spleen (splenectomy) may also be necessary to help reduce the destruction of red blood cells.
