dc.description.abstract | Background/Aims: The aims of this study were to determine the frequency of precore/core promoter mutations and hepatitis B e antigen (HBeAg)-negative chronic hepatitis B (e-CHB) in Korea. Methods: Patients with chronic hepatitis B virus (HBV) infection were tested for HBeAg, anti-HBe, liver profile and HBV-DNA by a branched DNA (bDNA) assay. Serum HBV-DNA was amplified by a polymerase chain reaction and the precore/core promoter sequence was determined. Results: Among the 413 consecutive HBeAg-negative patients, 19.6% were bDNA-positive. Evidence of liver disease was found in 90.1% of bDNA-positive and 41.7% of bDNA-negative patients. Overall, 17.7% of HBeAg-negative patients had e-CHB. Precore mutation (A1896) was detected in 93.7% of HBeAg-negative bDNA-positive and 93.9% of HBeAg-negative bDNA-negative patients. In 59 HBeAg-positive patients, 78% had wild-type and 22% had a mixture of wild-type and A1896 mutant. Core promoter TA mutation was detected in 89.9% of HBeAg-negative bDNA-positive patients, 89.8% of HBeAg-negative bDNA-negative patients, and 74.6% of HBeAg-positive patients. No correlation was found between the presence of precore/core promoter mutations and HBV-DNA levels or disease severity. Conclusions: In Korean patients infected with HBV genotype C, precore mutation occurred almost invariably along with HBeAg seroconversion and core promoter TA mutation was frequent irrespective of viral replication levels or disease severity.
