title: Reactivation of hepatitis B virus infection with an unusual pattern of serological markers.
abstract: A 73-year-old man presented with acute hepatitis, judged to be a reactivation of hepatitis B virus infection. His serum samples during a follow-up time of 16 months showed an unusual pattern of serological markers. He was consistently HBeAg positive, HBsAg fluctuated just under the cut-off value and he had a low level of circulating anti-HBs. By electron microscopy numerous aggregates of surface antigen particles, but not complete virions were seen. He was HBV DNA positive by hybridization. The complete precore and core genes and a region of the surface gene were amplified from his serum by PCR. These findings emphasize the need for expanded serological testing in some patients with acute clinical hepatitis.
