Table 2 Characteristics associated with changes in CD39 function

From: CD39 activity correlates with stage and inhibits platelet reactivity in chronic lymphocytic leukemia

  Characteristics Activity (pmol/min/50 K cells)
Stage 0–2 88.2*
  3–4 44.7
History of chemotherapy? Yes 55.8
  No 83**
Age < = 70 y/o 46.5*
  > 70 y/o 92
Hemoglobin < 13 g/dl 57.9
  > = 13 g/dl 89.4
  1. Statistically significant differences in CD39 activity. Stage, age, and hemoglobin levels were associated with statistically significant differences in the enzymatic activity of CD39 in patients with CLL. A history of chemotherapy was associated with a marginally significant trend towards decreased CD39 activity in CLL. Leukocyte and platelet count, gender, and length of time since diagnosis were not associated with differences in CD39 activity.
