Immune and inflammatory cytokines profile in Iraqi patients with acute and chronic myeloid leukemia
Keywords:Acute Myeloid Leukemia, Chronic Myeloid Leukemia, IL-6, TNF?, IL-2
Introduction and Aim: Evaluation of the profile of immunological and inflammatory cytokines, IL-6, IL-2 and TNF? in acute myeloid leukemia (AML) and chronic myeloid leukemia (CML) patients compared their level with healthy controls, and assessment of the association of these cytokines with clinical and hematological variables.
Patients and Methods: Thirty AML, thirty CML patients, and thirty healthy control individuals were recruited for this study from the National Hematology Center for Research and Treatment in Baghdad for the period of October 2020 to March 2021. Leukemic patients were under chemotherapy. Complete blood picture routine test and cytokines profile test were done. IL-6, IL-2 and TNF-? were quantitatively measured using enzymes linked immunosorbent assay (ELISA) kits.
Results: Hematological myeloid cancers affect more males than female, in AML male/female ratio was 17/13 while in CML was 16/14. The range of duration of the disease for both AML and CML was 1-3 years. in both AML group the level of IL-6 59.66 ± 31.99 pg/mL and in CML group 57.07± 16.52 pg/mL were both significantly higher P value < 0.001 than that of control group 37.95± 6.10 pg/mL. TNF? in AML group was significantly higher P value < 0.001 than that of control group. A high significant difference in serum level of IL-2 P value <0.0001 in AML and CML compared to controls.
Conclusion: IL-6, TNF? and IL-2 levels were higher in myeloid malignancy groups than controls. Serum cytokines shown to be positively associated with each other and could signify to poor outcome of the myeloid malignancy patients.
