Abstract:
Objective To observe the level of serum hepcidin and the relationship of hepcidin with renal anemia and micro-inflammation state in peritoneal dialysis(PD) patients.Methods Serum hepcidin,interleukin-6(IL-6),soluble transferrin receptor (sTfR) and erythropoietin (EPO) were measured in 50 PD patients with anemia,30 PD patients without anemia and 40 cases of normal control by ELISA.The indexes of blood routine examination,biochemistry and iron metabolism were also detected at the same time.Results The level of hepcidin in PD patients was significantly higher than that in normal control[(103.65±43.6) μg/L vs (56.39±35.7) μg/L,P ＜ 0.05].Furthermore,the level of hepcidin in PD patients with anemia was higher than that in PD patients without anemia [(122.67±36.6) μg/L vs (83.65±26.4) μg/L,P ＜ 0.05].The results of correlation analysis showed that serum IL-6,sTfR,EPO and ferritin were positively correlated with hepcidin(R =0.821,0.742,0.711,0.531,all P ＜ 0.05),while creatinine clearance of residual kidney in 24 hours and hemoglobin were negatively correlated with hepcidin(R =-0.533,-0.685,all P ＜ 0.05).Conclusions The higher level of hepcidin in PD patients is related with the residual renal function and the micro-inflammatory state.The higher level of hepcidin may induce the iron metabolism imbalance,and then influence the state of renal anemia.The adjustment of hepcidin may provide clinical research value of improving renal anemia and micro-inflammatory state in PD patients.
