Biochemical, virological, immunological and histopathological features of 702 incidentally detected chronic hepatitis B virus carriers in Bangladesh.
OBJECTIVE
Simultaneous assessment of biochemical, virological, and histological parameters of incidentally detected chronic hepatitis B virus (HBV)-infected subjects in Bangladesh were done to develop strategies for containment of HBV and management of liver diseases of these patients.


METHODS
A total of 702 chronic HBV carriers detected incidentally were enrolled in the study. Levels of HBV DNA and alanine aminotransferase (ALT) in sera were measured. The extent of hepatic inflammation and liver fibrosis was evaluated in all patients by examining liver biopsy specimens.


RESULTS
Of the 702 patients, 358 (50.7%) exhibited HBV DNA levels >10(5) copies/ml. ALT levels were above the upper limit of normal (ULN; >42 U/l) in more than 50% of the patients. High levels of HBV DNA (>10(5) copies/ml), increased ALT (>1.0 × ULN), moderate hepatic inflammation (HAI-NI ≥7) and severe hepatic fibrosis (HAI-F ≥3) were detected in 60 patients.


CONCLUSIONS
As considerable numbers of apparently healthy subjects are unaware of the fact that they are chronically infected by HBV, many of whom have already developed progressive liver damage, emergency strategies would be needed for the containment and management of HBV infection in developing countries.
