  • Background: To investigate liver damage and correlation between serum HBV DNA and quantitative HBsAg in HBeAg negative chronic Hepatitis B patients whose serum ALT levels are persistantly normal and HBV DNA levels are higher than 10.000 copies/mL.

    Methods: The patients who are HBsAg positive, HBeAg negative, older than 35 years old and whose HBV DNA levels are higher than 104 copies/mL while ALT level is normal at least one year before liver biopsy were included in the study. Liver needle biopsy was performed at all of the patients. Liver histopathologic findings were assessed by same pathologist according to the Ishak scoring system. Furhermore, HBV DNA and quantitative HBsAg were investigated from the patient's blood sample that are taken in the day of the liver biopsy. Chronic hepatitis B treatment indication was confirmed if necroinflamation score was >7 or fibrosis score was ≥2 according to the Ishak scoring system. SPSS 16.0 version was used for analysis of data.

    Results: Thirty patients were included in this study. Male and female patients were distrubuted equally. Mean age was 47,2 years (35-73 years). Moderate or over inflamation were detected in 6,7% of the patients. As seen in table 1, 30% of the patients' fibrosis score was ≥2 and these patients were decided to be treated and treatment was started for these patients (Table 1). Necroinflamation and fibrosis score were different  between the groups with low-normal and high-normal ALT. There was a good association between HBsAg and HBV DNA levels and between fibrosis score and HBV DNA levels.

    Conclusion: HBV infections have a different course in HBeAg negative patients. Liver biopsy should be done irrespective from serum ALT levels to the patients who are older than 35 years old in this group. HBsAg quantitation is a good marker as an alternative to HBV DNA in staging of chronic HBV infection.
