Cytokine profiles in acute myeloid leukemia patients at diagnosis

What is it about?

Several evidences support the existence of cytokine deregulation in acute myeloid leukemia (AML) patients that may be associated with pathogenesis, disease progression and patient survival. In the present study, we analyzed plasma levels of pro- and anti-inflammatory cytokines in AML patients and age-matched healthy donors. TNF-α, IL-6, IL-1β, IL-2, IFN-γ, IL-17A, IL-12p70, IL-8, IL-10, IL-4 and IL-5 were analyzed using fluorescent bead-based technology and TGF-β by ELISA technique.

Why is it important?

Our results showed that plasma TNF-α, IL-6 and IL-10 levels were higher in AML patients from both groups of age. IL-8 was increased in AML patients less than 65 years while the plasma concentrations of IL-4, IL-5 and IL-12p70 were significantly higher only in elderly AML patients compared with aged-matched healthy controls. Moreover, plasma levels of IL-6 and IL-10 were associated with patient survival and event-free survival.
