Abstract
A controlled trial was undertaken to evaluate adenine arabinoside in the treatment of hepatitis B surface antigen-positive chronic liver disease. Thirteen patients (7 hepatitis B virus DNA polymerase and hepatitis B e antigen-positive, 6 DNA polymerase-negative and hepatitis B e antibody-positive) were treated with adenine arabinoside. Eleven comparable patients served as controls and follow-up was for 6 mo. In the 7 hepatitis B e antigen-positive patients, adenine arabinoside produced a fall in DNA polymerase activity during treatment. When this effect was sustained, it was followed by a loss of e antigen (3 patients). Hepatitis B surface antigen concentrations and aspartate transaminase levels fell significantly at 6 mo. (P < 0.05) in the treated group compared with controls. In the hepatitis B e antibody-positive patients, adenine arabinoside treatment produced no significant change in hepatitis B surface antigen concentrations or aspartate transaminase levels at 6 mo. as compared with controls. Adenine arabinoside would appear to reduce, transiently or permanently, hepatitis B virus replication and it may therefore be useful in reducing the infectivity of some carriers of this virus. In the dose used, adenine arabinoside was ineffective in clearing hepatitis B surface antigen from the serum and eradicating hepatitis B virus from the liver, but combination with other antiviral or immunostimulant agents may enhance its therapeutic effectiveness.
