These cases could have been infected in the past, with the disappearance of anti-HBc; positive anti-HBe in these patients confirmed this possibility.
A precore mutant strain manifests as an infection with high concentrations of HBsAg and of HBV DNA, yet an absence of HBeAg and presence of antibody to HBeAg (anti-HBe).
HBeAg and anti-HBe detection by radio-immunoassay: correlation with vertical transmission of hepatitis B virus in Taiwan.
Serum hepatitis B virus deoxyribonucleic acid and serological indicators (HBsAg, anti-HBs, HBeAg, and anti-HBe) were determined before and every 3 months during PEG-IFN a-2a treatment.
In patients positive for HBsAg, additional testing may include hepatitis B e antigen (HBeAg), antibody to hepatitis B e antigen (anti-HBe), and HBV DNA qualitatively and quantitatively.
The following laboratory tests were performed: anti-HCV HCV RNA anti-HBs HBsAg Anti-HBe HBV DNA serum alanine amino transferase (ALT) aspartate amino transferase (AST) prothrombin time (PTT) total protein and albumin.
HBsAg, HBeAg and anti-HBe statuses were determined by enzyme immunassay (Organon Teknika BV, Boxtel, Netherlands) in all serum samples.
After the HBeAg levels become undetectable, antibody to hepatitis B e antigen (anti-HBe) becomes detectable at approximately week 16.
