BACKGROUND/AIMS: Hepatitis B virus infection is among the most devastating health problems in the world, including Turkey. In this cross-sectional study, we aimed to investigate the correlations between hepatitis B virus genomic load and various measures of the progression of chronic hepatitis B virus infection. METHODS: A total of 354 chronic HBsAg carriers [126 inactive HBsAg carriers, 50 asymptomatic replicative carriers (immune tolerant patients), 90 chronic hepatitis B patients and 88 patients with liver cirrhosis] were enrolled into the study. Eligible patients included males and females, 14-62 years of age, with detectable serum HBsAg, HBeAg or anti-HBe in serum at the time of screening and for at least six months before study entry. Serum hepatitis B virus DNA was detected by liquid hybridization, and results under the level of 1 pg/ml were additionally confirmed by polymerase chain reaction. RESULTS: Of 354 patients, 118 (33%) were HBeAg-positive and 236 (67%) HBeAg-negative. Of HBeAg-negative patients, 126 (53%) had normal alanine aminotransferase, 31 (13%) had elevated alanine aminotransferase (chronic hepatitis B) and 79 (33%) had evidence of cirrhosis; corresponding figures in the HBeAg-positive patients were 50 (42%), 59 (50%) and 9 (8%). There is a significant correlation between transaminase values and histological liver damage, whereas no correlation was found between viral replication and liver damage. CONCLUSIONS: Hepatitis B virus DNA is an important and specific marker for ongoing hepatitis B virus related liver disease, but alanine aninotransferase was shown to be the best marker for liver inflammation and not hepatitis B virus viral load. Although these findings are not new, they are of some utility since they prevent unnecessary and cost-intensive viral load determinations in chronic HBsAg carriers.
