  ABSTRACT: Objective: To detect the expression and significance of regulatory B cells in patients with immune thrombocytopenia. Methods: 73 ITP patients were divided into glucocorticoids treatment group (n = 42) and recombinant human thrombopoietin (rhTPO) treatment group (n = 31). According to the therapeutic effect, it was divided into effective group and ineffective group. The expression of CD19+ CD24hiCD38hi Breg in peripheral blood was detected by flow cytometry before and after treatment. The expression levels of transforming growth factor (TGF)-β1, interleukin (IL-10) and interferon (IFN)-γ were detected by ELISA before and after treatment. 30 volunteers were selected as the control group. Results: The expression of CD19+ CD24hiCD38hi Breg and cytokines IL-10 and TGF-β1 in 73 ITP patients before treatment was lower than that in the control group, while the expression of IFN-γ was higher than that in the control group (p β1 in the effective group were significantly higher than before treatment, while the expression of IFN-γ was significantly lower than before treatment (p + CD24hiCD38hi Breg, IFN-γ, IL-10 and TGF-β1 in the invalid group had no significant change compared with before treatment. Conclusion: Abnormal expression of CD19+ CD24hiCD38hi Breg and related cytokines is involved in the pathogenesis of ITP.
