Abstract:
Objective To study the dynamic changes of Hepcidin-25 in different disease process in patients with multiple myeloma (MM) and its relationship with therapeutic effect and prognosis.Methods The expression levels of Hepcidin-25 in 54 MM patients were analyzed by RT-PCR and ELISA.The correlations between dynamic changes of patients' Hepcidin-25 expression and clinical manifestations,clinical predictive value of the prognosis were researched.Results Expressions of Hepcidin-25 mRNA and protein in MM patients were significantly higher than those in normal control group [0.58±0.19 vs 0.08±0.027,P =0.001,(5.2±11.9) ng/ml vs (22.5±7.1) ng/ml,P =0.019].Hepcidin-25 expression of 17 patients remission after treatment was (26.4±7.3) ng/ml,it was significantly lower than that before treatment [(33.4±7.4) ng/ml,t =5.312,P =0.021].But the Hepcidin-25 level of the treatment ineffective patients (37 cases) significantly increased [(55.9±12.7) ng/ml vs (39.1±9.9) ng/ml,t =2.811,P =0.037].There existed obvious differences in survival curves of two groups (P ＜ 0.01).Hb level of patients remission after treatment was 124 g/L,and significantly higher than that before treatment (102 g/L,t =2.113,P =0.035).It had a negative correlation with Hepcidin-25 (r =-0.535,P =0.002).But the Hepcidin-25 level of the treatment ineffective patients significantly increased (46 g/L vs 73 g/L,t =2.730,P =0.036).It also had a negative correlation with Hepcidin-25 (r =-0.642,P =0.001).Conclusions Hepcidin-25 expression levels in patients with MM are high,and are closely related to anemia of chronic disease.High expression of Hepcidin-25 has a predictive value for clinical effect and prognosis.
