Abstract

Background: Interleukin-6(IL-6) is a pleiotropic cytokine that plays a major role in response to injury orinfections and involved in immune response, inflammation and haematopoiesis. It is produced by a variety ofcell types in response to variety of stimulants. Also deregulation impacts to numerous disease states, includingmany types of cancer. Elevated IL-6 levels have been observed in most types of cancer and it’s implicated inthe pathogenesis of several disease such as acute myeloid leukemia, multiple myeloma, lymphoma and it maybe a prognostic factor for solid tumors, such as prostate cancer.Objectives: Estimation of the serum levels of IL-6 in patients with AML in different stages of the disease andassess their prognostic value and study its relationship with bacteremia, total leukocyte count ,and hemoglobinconcentration.Materials and Methods: Forty patients of AML in different stages in National centre of hematology-Baghdadwere studied immunologically for the detection of serum IL-6 by Enzyme Linked Immune SorbentAssay(ELISA) kit. Specimen of blood collected from AML in relapse stage with episode of fever, were subjectedto well known established microbiological methods for diagnosis and identification of isolates and datawere compared with 20 healthy donors.Results: Newly diagnosed and in relapse stage patients with AML had significantly higher serum levels ofIL-6 compared with both control group and leukemic patients in remission stage P<0.05,in addition there wasa positive correlation of IL-6 with the presence of fever due to bacterial infection .The clinical specimen resultin(8) isolates, from which (6) were coagulase negative and (2) were staphylococcus aureus ,all isolates showhigh sensitivity to erythromycin and high resistant to chloromphenicol .Also IL-6 level correlated positivelywith total leukocyte count (TLC) and inversely with hemoglobin (Hb) concentration in AML at diagnostic andrelapse stage.Conclusion: Serum levels of Interleukin-6 can be used as prognostic serum markers at diagnosis of adultsacute myeloid leukemia and it could be used as follow up parameters for early detection of relapse stage, inaddition it seem to be a good markers to detect patients with bacteremia.
