Study on correlation between viral replication and liver fibrosis indicators in patients with chronic hepatitis B in Lanzhou / 国际检验医学杂志

ABSTRACT

Objective To investigate the correlation between the liver fibrosis markers laminin(LN),hyaluronan acid(HA),col-lagen Ⅳ(CⅣ)and procollagen type Ⅲ N-terminal peptide(PⅢNP)with the replication of hepatitis B virus(HBV)DNA in the pa-tients with chronic HBV in Lanzhou.Methods Real-time PCR and chemiluminescent immunoassay(CLIA)were used to quantita-tively measure serum HBV-DNA and liver fibrosis markers in 724 cases of HBV infection in Lanzhou with the different clinical classifications and the natural history stage as the background.Results The values of the liver fibrosis indicators and HBV-DNA level in all clinical types were higher than normal levels,and reached to maximum in the liver cirrhosis goup;CⅣ and PⅢNp were highest in the HBeAg (+)CHB group;according to the hepatitis B natural history stage,the PⅢNP and CⅣ values reached the peak value in the immune clearance phase,moreover the CⅣmean value in the HBeAg and HBV-DNA (+)group was higher than that in the HBV-DNA and HBeAg (-)group.4 indicators in the HBeAg (+)CHB group were higher than those in the HBeAg (-)CHB group,but only HA had statistical difference(P <0.01 ).Conclusion There is certain correlation between CⅣ with HBV-DNA and HBV-M,indicating that which can indirectly reflect the degree of liver damage and viral replication level.
