Significance of Serum Transferrin Receptors and Iron Overload in Children with Hemoglobin H Disease / 实用儿科临床杂志

ABSTRACT

Objective To measure the levels of serum transferrin receptors (sTfR) and serum ferritin (SF) in children with hemoglobin H disease for investigation the iron metabolism(sideropenic or iron overload) and to guide the proper intervention.To get a best index of judging the iron overload in HbH children by analysis of the values of sTfR and sTfR/lgSF.Methods Peripheral blood specimens were obtained from 50 cases of HbH children and 30 cases of healthy normal controls,the levels of sTfR and SF were examined by enzyme linked immunosorbent assays(ELISA).The diagnosis efficiency of sTfR and sTfR/lgSF in HbH children′s iron metabolism was judged by receiver operator cha-racteristic (ROC) curve analysis.Results The level of sTfR in HbH group was (6.74?1.02) mg?L-1,which was significantly lower than that in healthy control group[(8.09?0.67) mg?L-1](P
