title: Analysis of approach to therapy for chronic liver disease in an HCV hyperendemic area of Japan.
abstract: In 1990, we conducted an epidemiological study of 509 residents in a hepatitis C virus (HCV) hyperendemic area in Japan. The purpose of the present study was to examine the approach to therapy for liver diseases accompanied by HCV and hepatitis B virus (HBV) infections among the surviving residents in the town after 12 years. Fifty-three with HCV or HBV infections among 385 people who resided in the town were clearly analyzed in 2002. The number of persons diagnosed with the liver diseases was as follows: HCV-related asymptomatic healthy carrier (1), past history of HCV infection (15), chronic hepatitis C (22), HCV-related liver cirrhosis (6), HCV-related hepatocellular carcinoma (HCC) (5), and HBV-related asymptomatic healthy carrier (4). HCC was detected in residents who did not have periodic regular hospital checkups. Only 19% of the 53 inhabitants consulted liver medical specialists, and 75% (3/4) who received interferon therapy received treatment from a liver medical specialist. It is necessary to provide continuous medical treatment to HCV carriers, minimizing difference in treatment quality in different medical institution. An efficient HCV medical checkup and a program of subsequence health management are important problems to be solved for improved health care.
