Abstract: BACKGROUND: Acute myeloid leukemia (AML) is a clonal malignant condition of immature hematopoietic cells, characterized by clonal proliferation of abnormal cells (blasts) in the marrow leading to impairment of the normal blood cell production giving rise to failure of the bone marrow. Soluble interleukin-2 (IL-2) receptor alpha chain is a protein that is involved in the assembly of the high-affinity IL-2 receptor, and it has a critical role in controlling immune system homeostasis. The overexpression of sIL-2RA was investigated in many hematopoietic malignancies, and it was correlated with poor outcome. OJECTIVES: The aim of this study was to assess the sIL-2RA level as a prognostic factor and assess its impact on survival and if it can be used as a targeted treatment for a better outcome. MATERIALS AND METHODS: Sixty newly diagnosed adults with AML before starting therapy were included in the study, and they were followed up for 6 months to document survival status. Thirty healthy adults were taken as a control group. Using an enzyme-linked immunosorbent assay, the plasma sIL-2RA level was measured. Statistical analysis was done using Microsoft Excel 2019 and version 26 SPSS statistical software. P <0.05 was considered statistically significant. RESULTS: A considerable difference in the plasma sIL-2RA level between AML patients and controls also was more elevated in patients who died after 6-month follow-up. According to the blast percentage, total white blood cell count, and M0-M2 subgroups, the sIL-2RA level correlated positively. Irrelevant association was found regarding the patients’ age, the count of platelet, and the hemoglobin. CONCLUSIONS: Plasma sIL-2RA level is higher in AML patients than the control group at the time of diagnosis. Patients with a high level of plasma sIL-2RA have an inferior (overall survival) and poor outcome. SIL-2RA level is higher in M0-M2 subgroups than other subtypes. There is a significant association between sIL-2RA level and the absolute count of leukemic blasts.
