The aim of this study was to evaluate the effect of interferon-alpha therapy on serum and liver HBV DNA in 20 patients with chronic hepatitis B and to correlate the presence or absence of HBV DNA with the clinical response. There were 11 responders and all lost HBV DNA from the serum. Ten of the 11 were followed for 36 months following IFN treatment and remained well with absence of HBeAg and HBV DNA from the serum and with normal ALT. Five also lost HBsAg. HBV DNA became undetectable in the liver of nine of 10 of these patients in whom liver tissue was available for study. HBV DNA persisted in the liver of seven of nine nonresponders and was not detected in two in spite of the presence of HBV DNA and HBeAg in the serum of these two patients. We conclude that IFN may induce long remissions in patients with chronic hepatitis B with loss of HBV DNA from the serum and that occasionally HBV DNA may persist in the liver of such patients.

D006509 Hepatitis B INFLAMMATION of the LIVER in humans caused by a member of the ORTHOHEPADNAVIRUS genus, HEPATITIS B VIRUS. It is primarily transmitted by parenteral exposure, such as transfusion of contaminated blood or blood products, but can also be transmitted via sexual or intimate personal contact. Hepatitis B Virus Infection
D006513 Hepatitis B e Antigens A closely related group of antigens found in the plasma only during the infective phase of hepatitis B or in virulent chronic hepatitis B, probably indicating active virus replication; there are three subtypes which may exist in a complex with immunoglobulins G.

D006514 Hepatitis B Surface Antigens Those hepatitis B antigens found on the surface of the Dane particle and on the 20 nm spherical and tubular particles. Several subspecificities of the surface antigen are known. These were formerly called the Australia antigen. Australia Antigen,HBsAg,Hepatitis B Surface Antigen,Antigen, Australia
D006515 Hepatitis B virus The type species of the genus ORTHOHEPADNAVIRUS which causes human HEPATITIS B and is also apparently a causal agent in human HEPATOCELLULAR CARCINOMA. The Dane particle is an intact hepatitis virion, named after its discoverer. Non-infectious spherical and tubular particles are also seen in the serum.
