Abstract:
Objective To evaluated the association between the NAGL and the chronic kidney disease (CKD) patients with iron status,which was occurred iron scarcity for CKD patient in clinical.Methods 154 CKD patients were included in this study.Serum neutrophil gelatinase-related lipid transport protein(NGAL) were detected in anemia group and non-anemia group of chronic kidney disease.The NGAL,univariate correlation and multivariate regression analysis,as well as ROC curve analysis,were used to assess and compared the diagnostic potential of NGAL,ferritin,EPO and Tfr (transferrin receptor) in CKD patients after analyzing the patient's iron status.Results NGAL levels were markedly higher in CKD patients with anemia than CKD patients without anemia.In the analysis,NGAL was inverse correlated with hemoglobin,hematocrit,MCV,MCH,serum iron and TSAT(correlation relation was-0.36,-0.32,-0.26,-0.31,-0.38,-0.3,respectively).ROC analysis was employed to assess and compare the diagnostic potentials of the NGAL,ferritin,EPO,and Tfr (transferritin receptor) in identifying this condition among CKD patients.The NGAL showed that the area under the curve of iron deficiency in CKD patients (AUC) was 0.713,with good sensitivity and specificity (58.6％ vs 74.7 ％).Conclusion NGAL might be proposed as a new tool in the assessment of iron deficiency and in the management of iron therapy for CKD patients.
