[Clinical Significance of Hepcidin in the Diagnosis of Infant Iron Deficiency Anemia]
OBJECTIVE To explore the clinical diagnostic value and significance of hepciden level by detecting the expression of serum hepcidin before and after treatment of infant iron deficiency anemia (IDA) with or without vitamin D deficiency. METHODS A total of 60 cases of infamt IDA were divided into A and B groups, the group A consisted of 20 IDA infants with vitamin D deficiency, group B consisted of 48 IDA infants without vitamin D deficiency and the control group included 26 healthy infants. Blood examination including HGB, MCV, MCH and MCHC was performed by hematological analyzer, the level of serum ferritin was assayed by chemiluminescence immunoassay, the levels of hepcidin and 25 (OH) D were assayed by ELISA. RESULTS The levels of serum hepcidin in group A, B and control group before treatment were (29.16 7.50) (27.11 7.10) and (29.25 8.39) ng/ml, respectively (P 0.05) The level of serum hepcidin in group A and B after treatments was significantly higher than that in control group (36.21 5.68) ng/ml vs (29.25 8.39) ng/ml, P 0.01; (34.16 4.54) ng/ml vs (29.25 8.39) ng/ml, P 0.01] but there were no significantly difference between group A and B (P 0.05) The serum ferritin positively correlated with hepcidin in group B both before and after treatments (r 0.352 and 0.367, P 0.05, P 0.05) CONCLUSION The level of serum hepcidin has an important significance in poccess of evaluatng for therapeutic effect in infant iron deficiency anemia, but the interference effect of vitamin D deficience should be eliminated when the expression level of hepcidin is applicated for diagnosis and differential diagnosis.
