Correlations betweenintrahepatic HBsAg and HBcAg levels and serum HBsAg and HBV DNA levels in low-level HBsAg patients / 实用医学杂志

ABSTRACT

Objective To analyze the relationship between intrahepatic expression of HBsAg and HBcAg and the serum HBsAg and the load of HBV DNA in low-level HBsAg.To provide the basis for the diagnosis of low-level HBsAg.Methods A total of 63 patients with HBsAg lower than 1 400 IU/mL and higher than 0.05 IU/mL were enrolled in the study.All the 63 patients with low level HBsAg were collected for liver biopsy from January 2013 to December 2015.Serum HBsAg was detected by Roche cobas e601 automatic electrochemiluminescence immunoas-say system and supporting reagents.HBV DNA was detected using ROCHE automatic AmpliPrep/cobas TaqMan 48 system detector and supporting reagents.Results Among the 63 patients,the HBsAg in liver tissue was negative in 5 cases(7.94%),+in 47 cases(74.60%),++in 8 cases(12.70%),+++in 2 cases(3.17%),and++++was found in 1 case.The expression of HBcAg were negative in 30 cases(47.62%),+in 28 cases(44.44%),++in 4 cases(6.35%),+++in 1 case(1.59%),and++++in 0 cases.There was a significant positive correlation between HBsAg expression and serum HBsAg level by spearman and kendall correlation analysis(spearman analysis:r = 0.261,P=0.039;kendall analysis:r=0.217,P=0.036).HBcAg expression was significantly correlated with serum HBV DNA load with spearman and kendall correlation analysis(spearman analysis:r=0.305,P=0.015;kendall analysis:r=0.259,P=0.017).Conclusions The expression of HBsAg in liver tissue of in the patients with low level of HBsAg is positively correlated with the level of serum HBsAg,but not with the load of HBV DNA. There is significant positive correlation between HBcAg expression and serum HBV DNA load.
