Erythrocyte pyruvate kinase activity in patients with haematological malignancies. 1975

V S Tanphaichitr, and J van Eys

Erythrocyte pyruvate kinase (PK) activity was decreased with acute myelomonoblastic leukaemia (AML) and lymphosarcoma cell leukaemia (LSAL) but increased in patients with chronic myelocytic leukaemia (CML). There was no difference in the enzyme activity between controls and relatives of patients with AML. PK activity in patients with ALL during complete remission was higher than during untreated and relapsed stages. These data provided evidence that the altered enzyme activity is acquired rather than genetic. There was a positive correlation between PK activity and red cell creatine levels. The red cell creatine was low in patients with AML but high in patients with CML. This suggests that the altered enzyme activity in these patients is at least part due to red cell age.

UI	MeSH Term	Description	Entries
D007223	Infant	A child between 1 and 23 months of age.	Infants
D007938	Leukemia	A progressive, malignant disease of the blood-forming organs, characterized by distorted proliferation and development of leukocytes and their precursors in the blood and bone marrow. Leukemias were originally termed acute or chronic based on life expectancy but now are classified according to cellular maturity. Acute leukemias consist of predominately immature cells; chronic leukemias are composed of more mature cells.

D011087	Polycythemia Vera	A myeloproliferative disorder of unknown etiology, characterized by abnormal proliferation of all hematopoietic bone marrow elements and an absolute increase in red cell mass and total blood volume, associated frequently with splenomegaly, leukocytosis, and thrombocythemia. Hematopoiesis is also reactive in extramedullary sites (liver and spleen). In time myelofibrosis occurs.
