ABSTRACT
OBJECTIVE: To observe the expression of helper T cells 17(Th17), interleukin 23 (IL-23) in peripheral blood in patients with acute myeloid leukemia (AML), to analyze the relationship between Th17, IL-23 in peripheral blood and immunophenotype.
METHODS: 105 patients with AML in the hospital from January 2019 to January 2021 were prospectively selected as the research subjects, the expression of Th17 and IL-23 in peripheral blood of patients with AML was detected by flow cytometry; immunophenotype was detected and counted. The relationship between the expression of Th17, IL-23 in peripheral blood and immunophenotype of AML patients was analyzed. Draw ROC curve and analyze the predictive value of Th17 and IL-23 expression in peripheral blood to immunophenotype.
RESULTS: The immunophenotype results of AML patients showed that myeloid antigen, lymphoid antigen and hematopoietic stem/progenitor cell marker antigen were positive expressed for various antigens in 105 AML patients, in myeloid antigens, CD13+ accounted for the highest proportion (93.33%), in lymphoid antigens, CD56+ accounted for the highest proportion (32.38%), and in hematopoietic stem/progenitor cell marker antigens, CD38+ accounted for the highest proportion (68.57%). The expression of Th17 in peripheral blood of AML patients with CD56+, CD7+, CD34+ and human leukocyte antigen DR+(HLA-DR+) were higher than that of AML patients with CD56–, CD7–, CD34–, HLA-DR–, the expression of IL-23 in peripheral blood of AML patients with CD56+, CD34+ and HLA-DR+ were higher than that of AML patients with CD56–, CD34–, HLA-DR–, the differences were statistically significant (P<0.05); compared the expression of Th17 and IL-23 in peripheral blood between other antibody positive and negative patients, there was no statistical significant difference (P>0.05). Logistic regression analysis showed that the high expression of Th17 in patients with AML was related to the positive expression of CD56, CD7, CD34 and HLA-DR in the detection of immunophenotype, the high expression of IL-23 was related to the positive expression of CD56, CD34 and HLA-DR in the detection of immunophenotype. The ROC curve showed that the AUC of expression levels of Th17 and IL-23 in peripheral blood alone and in combination for predicting CD56+, CD34+, HLA-DR+ and Th17 in peripheral blood for predicting CD7+ were mostly 0.5-0.7, which had certain predictive value, but the predictive performance was low.
CONCLUSION: Myeloid antigen, lymphoid antigen and hematopoietic hematopoietic stem/progenitor cell marker antigen are positive expressed for various antigens in AML patients, the high expression of Th17 in peripheral blood of AML patients is related to the positive expression of CD56, CD7, CD34 and HLA-DR in detection of immunophenotyping, the high expression of IL-23 is related to the positive expression of CD56, CD34 and HLA-DR in the detection of immunophenotype.
