| Research Abstract |
HBV is the leading cause of chronic liver disease in Asian countries and it is also important issue in public health. About 90% of the patients go into persistent remission with low HBV replication. Host immune response is a crucial factor that controls HBV replication. Nucleotide analogues are important anti-HBV drugs that suppress HBV replication effectively, however, long-term usage of the drugs induces resistant HBV clone that usually results in breakthrough hepatitis. We also sometimes experience persistent suppression of HBV replication after ALT flare-up.
Therefore, we administered 3TC during 3-4 months and examined gene expression in PBMC after the withdrawal using cDNA microarray. In eight of ten cases, serum transaminases flared and HBV replication was suppressed in three of eight cases.
Results of the present study indicate that induction of interferon related genes and CTL related genes might be related the suppression of HBV replication.
