Direct-acting antiviral treatment is safe and effective for chronic HCV patients with psychiatric disorders

Although most patients with hepatitis C virus (HCV) infection have been cured since the introduction of direct-acting antiviral (DAA) treatments, whether patients with psychiatric disorders and chronic HCV infection receive benefits from DAA treatments remain unclear. The efficacy and safety of DAA treatment were compared between patients with and without psychiatric disorders. Data were retrospectively collected from medical records at the Suzuka General Hospital (Japan) between September 2014 and December 2021. The study was an observational, single-center study. Fisher's exact test, Mann-Whitney U test and Friedman's test were used for the comparisons between groups. Patients with HCV infection who had been started on DAA treatments were included. In total, 15 HCV cases with psychiatric disorders (P) and 209 HCV cases with nonpsychiatric disorders (NP) were started on DAA treatments for HCV infection. Patients in group P were younger (55 & PLUSMN;13.9 years) compared with those in group NP (68 & PLUSMN;13.0 years). A total of 12 patients (80%) in group P achieved and 188 patients (90%) in group NP achieved sustained virologic response (SVR), with no significant difference between the two groups. The remaining three patients in group P who did not achieve SVR included two drop-out cases. Regarding the laboratory data at the end of DAA treatments and SVR, there were no significant differences between the two groups. There were no cases of discontinuation or reduction of medication due to psychiatric disorders during DAA treatment. DAA treatment for HCV infection is effective, tolerable and safe for psychiatric patients, as well as patients without psychiatric disorders. Psychiatric patients with HCV infection should undergo DAA treatment to prevent progression to liver failure and/or cancer.
