A 41‐year‐old woman with chronic hepatitis C was treated with pegylated‐interferon (PEG‐
IFN)‐α‐2b plus ribavirin for 24 weeks. She had hepatitis C virus (HCV) genotype 2a (1600
KIU/mL), and her liver histology showed mild inflammation and fibrosis. Four weeks after the
start of the therapy, she achieved a rapid virological response (RVR) and then a sustained
virological response (SVR). Serum alanine aminotransferase (ALT) levels remained within

A 41‐year‐old woman with chronic hepatitis C was treated with pegylated‐interferon (PEG‐IFN)‐α‐2b plus ribavirin for 24 weeks. She had hepatitis C virus (HCV) genotype 2a (1600 KIU/mL), and her liver histology showed mild inflammation and fibrosis. Four weeks after the start of the therapy, she achieved a rapid virological response (RVR) and then a sustained virological response (SVR). Serum alanine aminotransferase (ALT) levels remained within normal ranges and HCV RNA continued to be negative. However, ALT levels flared with the re‐emergence of HCV RNA in the serum 1.5 years after discontinuation of therapy. HCV RNA obtained from sera before therapy and after relapse shared a 98.6% homology with the E2 region, and phylogenetic analyses indicated that they were the same HCV strain. These results eliminated the possibility of a re‐infection and strongly indicated a late relapse of the disease. Therefore, follow‐up is necessary for chronic hepatitis C patients after SVR, even if they respond well to therapy, including RVR.
