Recently, the issue of Hepatitis B Virus (HVB) mutation is becoming a significant point to consider. The mutation might render
significant problems as the virus might escape from the detection method, vaccination induced-protection and treatment modalities. The
study was to analyze the profile of serological parameters in the HVB infected serum in Surakarta. As many as 36 HBsAg-positive sera
were randomly retrieved from the patients in Moewardi Hospital and donors in Blood Bank of Indonesian Red Cross (PMI) in Surakarta
during August-September 2007. Having analyzed by immunoanalyzer, 13 (36.1%) of 36 sera were HBeAg-positive suggesting an active
infection and potent of transmission. Interestingly, 3 (8.3%) of 36 sera were Anti-HBs-positive, while the other 5 (13.8%) showed
detected level of Anti-HBs even lower than the cut-off (12 mIU/ml). Accordingly, 22 (61.1%) of 36 serum were Anti-HBe-positive, while
one (2.8%) sera was HBe-Ag-positive as well as Anti-HBe-positive. The data suggested some possibilities: double infection with two or
more subtypes of HBV, mutation resulting in quasi-species phenomenon, or the so-called healthy carrier. More extensive and specific
studies are necessary to confirm and elucidate the profile.
