BACKGROUND: Hepatitis B virus (HBV) DNA has been detected in the peripheral blood leukocytes (PBL) during acute and chronic HBV infection. Possible pathobiologic significance includes infectivity and altered immunity. There are few data relating PBL HBV-DNA with severity of the liver disease, in particular with hepatocellular carcinoma (HCC).
METHODS: HBV-DNA was detected by dot-spot hybridization technique in PBL separated from venous blood samples of 209 hepatitis B surface antigen-positive patients (28 healthy carriers and 95 chronic hepatitis, 29 cirrhotic, and 57 HCC patients). Serum HBV-DNA and hepatitis B e-antigen (HBeAg) were also measured.
RESULTS: Thirty percent of HCC patients were hepatitis e-antigen-positive compared to 50%, 84% (P < 0.0001), and 69% (P < 0.00001) of healthy carriers and chronic hepatitis and cirrhotic patients, respectively. Furthermore, only 11% of HCC patients had detectable serum HBV-DNA compared to 39% (P < 0.001), 58% (P < 0.001), and 31% (P < 0.05) of these respective patient groups. despite low viral replication among HCC patients, 58% had PBL HBV-DNA. Corresponding figures for healthy carriers and for chronic hepatitis and cirrhotic patients were 39%, 58%, and 56%. Fifty-two percent of HCC patients had positive PBL HBV-DNA in the absence of serum HBV-DNA, compared with 25% in healthy carriers (P < 0.05) and 22% in chronic hepatitis (P < 0.001) and 35% in cirrhotic patients (P = NS).
CONCLUSION: The high detection rate of PBL HBV-DNA among HCC patients may reflect certain pathogenetic processes of HBV infection and indicate a higher risk of development of HCC.
