    Abstract:
    A previous randomized controlled study has shown a 30% rate of HBe antigen/antibody seroconversion within 1 year of a month course of adenine arabinoside-5'-monophosphate; no seroconversion occurred in the control group. In this study of patients derived from the same population, 45 hepatitis B virus carriers with chronic liver disease were randomized to receive either a short (4-week) course of adenine arabinoside-5'-monophosphate, a long (7 to 8-week) course of adenine arabinoside-5'-monophosphate or a 12-week course of lymphoblastoid interferon. Long-lasting suppression of hepatitis B virus replication with disappearance of serum hepatitis B virus DNA and clearance of HBeAg occurred within 12 months of treatment in four patients who received the short course of adenine arabinoside-5'-monophosphate and in five who received interferon. Of the nine responders, four also lost HBsAg. A response to antiviral therapy was accompanied by clinical and biochemical evidence of improvement in liver disease. None of the patients who received a long course of adenine arabinoside-5'-monophosphate responded. Peripheral neuropathy and myalgia were the most serious adverse effect affecting three recipients of the short course of adenine arabinoside-5'-monophosphate and eight recipients of the long course. Thrice weekly administration of interferon was well-tolerated. Further studies to identify the characteristics of the "responder patients" and large-scale controlled trials of antiviral therapy in these subgroups are indicated.
