Abstract

Hepatitis B and C (HBV and HCV) testing has been performed in Japan since 2002 and is subsidized by central and prefectural governments. A follow-up program for HBV- or HCV-infected persons was started at that time in Ishikawa Prefecture. This study analyzed the long-term follow-up data from this program. In total, 1029 participants in the Ishikawa Hepatitis Follow-up Program (HBV-infected, n = 535; HCV-infected, n = 494) were enrolled. Clinical data between the first visit and the most recent visit by March 2019 were collected. In the HBV-infected group, 384 persons (71.8%) were asymptomatic carriers, 133 (24.9%) developed chronic hepatitis, 15 (2.8%) developed compensated liver cirrhosis, and 3 (0.6%) developed decompensated liver cirrhosis. Ninety (16.8%) were treated with nucleotide/nucleoside analogs. Sixteen (3.0%) developed liver cancer. In the HCV-infected group, 427 persons (86.4%) developed chronic hepatitis, 46 (9.3%) developed compensated liver cirrhosis, and 21 (4.3%) developed decompensated liver cirrhosis. Forty-eight (9.7%) developed liver cancer. Three hundred and seventy-eight (76.5%) received antiviral therapy (a direct-acting antiviral in 166, interferon-based treatment followed by a direct-acting antiviral in 73, and interferon-based treatment in 139). The subsidy system was used by 270 persons (71.4%). Sustained virological response was confirmed in 340 persons (68.8%). A higher FIB-4 index at the first visit was a significant risk factor for liver cancer in HBV-infected and HCV-infected persons. The Ishikawa Hepatitis Follow-up Program has revealed the clinical course of HBV and HCV infection in community-dwelling individuals. The results will be used for micro-elimination at a prefectural level.
