ABSTRACT
BACKGROUNDS/AIMS:
The ultimate goal of antiviral therapy using interferon/pegylated interferon combined with ribavirin in chronic C-viral hepatitis is to achieve a sustained virologic response (SVR). Several studies have shown that the reappearance rate of hepatitis C virus (HCV) RNA in serum after the achievement of an SVR is less than 1%; the durability of an SVR in Korean patients is not known. The aim of this study was to determine the durability of the virologic response in chronic hepatitis C patients with an SVR to antiviral therapy.METHODS:
A total of 156 patients who were treated successfully with interferon/peginterferon and ribavirin were evaluated retrospectively. Patients received either subcutaneous conventional interferon alpha 3x10(6) units three times a week or subcutaneous pegylated interferon (alpha-2a 180 microgram, alpha-2b 80-100 microgram) once a week in combination with ribavirin at 600-1,200 mg daily (depending on body weight). Patients with HCV genotype 1 were treated for 48 weeks, whereas those with non-genotype 1 were treated for 24 weeks.RESULTS:
Eighty-two patients underwent treatment with conventional interferon and ribavirin, whereas 74 patients were treated with pegylated interferon and ribavirin. An SVR was achieved in 73 patients (73/156, 46.8%). HCV RNA reappeared in eight patients (8/73, 11.0%; detected by qualitative PCR), including one patient with persistent viremia (1/73, 1.4%).CONCLUSIONS:
Reappearance of HCV RNA after earlier achievement of an SVR might appear more frequently than previously reported. Close follow-up of these patients is recommended and the implication of temporary viremia should be determined in the future.
