Clinical Application Value of Chitinase-3-like Protein 1 in Patients with Different Liver Diseases / 现代检验医学杂志

ABSTRACT

Objctive To explore the clinical value of Chitinase-3-like protein 1(CHI3L1)in patients with chronic hepatitis B (CHB),liver cirrhosis and liver cancer.Methods 96 clinically diagnosed patients in Department of Infectious Diseases Hos-pital of Anhui Provincial Hospital from Jan 2016 to Feb 2017(28CHB,44livercirrhosis,24liver cancer,15healthy controls) were analyzed.The serum level of CHI3L1 was measured by enzyme-linked immunosorbentassay(ELISA).The Golgi pro-tein(GP73)was tested by double-antibody sandwich immunochromatographic assay.The Alpha-fetoprotein(AFP)was tested by means of chemical luminescence.Results There were significant differences between the groups of chronic hepati-tis B(CHB),liver cirrhosis,liver cancer and healthy controls on the CHI3L1 level(χ2=70.249,P<0.001).The CHI3L1 level of the liver cirrhosis group and the liver cancer group increased significantly compared with that of the healthy controls (P<0.001).The GP73 levels of these groups were significantly different(χ2=44.963,P<0.001).The GP73 levels of the CHB group,the liver cirrhosis group and the liver cancer group all increased significantly compared with that of the healthy controls(P<0.05).The AFP levels of these groups were significantly different(χ2=57.606,P<0.001).The AFP level of the liver cancer group increased significantly compared with that of the CHB group,the liver cirrhosis group and the healthy controls(P<0.001).Based on the receiver operating characteristic(ROC)curve of CHI3L1,GP73 and AFP in the CHB group and the liver cirrhosisgroup,the Area Under roc Curve(AUC)of CHI3L1 was 0.953(95%CI0.902~1.000),the sensitivity was 88.6%,and the specificity was 92.9%,which was higher than GP73 and AFP.Based on the ROC curve of CHI3L1,GP73 and AFP in the liver cirrhosis group and the liver cancer group,the AUC of AFP was 0.930(95% CI0.871~0.989),the sensitivity was 75.0%,and the specificity was 97.7%,which was higher than CHI3L1 and GP73.The corre-lation between the CHI3L1,GP73 and AFP in CHB,liver cirrhosis and liver cancer groups were analyzed.There was a posi-tive correlation between AFP and GP73(rs=0.491,P<0.001),a positive correlation between AFP and CHI3L1(rs=0.452,P<0.001),a positive correlation between GP73 and CHI3L1(rs=0.554,P<0.001).Conclusion CHI3L1 is good at diagnosis of liver cirrhosism,better than GP73 and AFP.And AFP could be more beneficial in patients with liver cancer, better than CHI3L1 and GP73.
