Background Incarcerated persons are a special population with higher hepatitis C virus (HCV) prevalence and should be prioritized for micro-elimination. This study aimed to investigate the seroprevalence and to evaluate the effectiveness and safety of direct acting antiviral (DAA) therapy in the custodial settings. Methods Incarcerated persons in Yunlin Prison were recruited to receive anti-HCV antibody screening. Patients with positive HCV ribonucleic acid (HCV RNA) were treated with glecaprevir/pibrentasvir (GLE/PIB) in our special chronic hepatitis C (CHC) clinic in prison. The primary endpoint was sustained virologic response at week 12 off therapy (SVR12). Results A total of 1402 incarcerated persons were invited to anti-HCV screening and 824 (58.7%) accepted. The prevalence of anti-HCV positivity was 33.5% (276/824) and the viremic rate (detectable HCV RNA) was 69.2% (191/276). According to FIB-4 index, patients with F3 stage were six (3.1%), but none met the criteria of F4 stage. However, six (3.1%) had liver cirrhosis with splenomegaly, confirmed by findings of ultrasonography. The median log10 HCV RNA level at baseline was 6.235 (2.394-7.403). Genotype (GT) 6 was predominant (39.3%), followed by GT 1a (22.0%) and 1b (14.1%). Mixed genotype HCV infection accounted for 3.6% of total infections. In total, 165 patients received GLE/PIB therapy. The overall SVR12 rates were 100%. Conclusions DAA therapy is highly effective and safe for incarcerated patients in Taiwan. Our special prison-based CHC clinic, linking universal screening to medical care, can serve as a model for micro-elimination of HCV in custodial settings.
