• Chronic myeloid leukemia
• Interleukin-1 beta
• Imatinib mesylate

Chronic myeloid leukemia (CML) is a myeloproliferative disorder characterized by the presence of an acquired mutation which affects the hematopoietic stem cell, leading to a striking overproduction of immature granulocytes. The first important clue to its pathogenesis the Philadelphia chromosome created by a reciprocal translocation between chromosomes 9 and 22 (t [9; 22] [q34; q11]). The development of the BCR-ABL-targeted imatinib mesylate represents a paradigm shift in the treatment of CML. Imatinib displays inhibitory activity against other kinase(s) that play a role in monocyte/macrophage development. Accordingly many studies revealed the role of cytokines in pathophysiology of myeloid neoplasia including participation of IL-1 beta in the pathogenesis of CML. This study designed to assess the behavior of IL-1 beta through newly diagnosed patients, different responders groups (optimal, suboptimal and failure cytogenetic response) and advanced stages (acceleration and crisis groups) of CML Iraqi patients whom receiving Imatinib mesylate (tyrosine kinase inhibitor), trying to elucidate the role of immunity in pathophysiology of CML disease development and treatments. In this study 96 Iraqi CML patients under imatinib mesylate treatment categorized by complete blood picture and fluorescent in situ hybridization analysis into different response groups and stages, then used an enzyme linked immunosorbent assay technique to assess serum level of IL-1 beta in each response group and advance stage (acceleration and transformed) of CML patients, in comparison to level in 32 healthy control subjects and 32 newly diagnosed CML. Out of 128 patients the mean serum of interleukin 1 beta level (pg/ml) for the newly diagnosed, optimal responded, suboptimal responded, failure cytogenetic and advance stage of CML were 6.53 +/- A 3.81, 18.47 +/- A 4.29, 18.69 +/- A 3.03, 5.73 +/- A 2.44, and 18.10 +/- A 3.10, respectively. While healthy was 12.17 +/- A 3.44. The measurement of IL-1 beta before and during treatment of CML patients may contribute to the early identification of responder and non responder patients, and help in the earlier choice and/or design of alternative therapeutic strategies.
