Epidemiological Survey of Patients With Hemodialysis Complicated by Hepatitis C in Japan.

Nowadays, interferon-free direct-acting antiviral (DAA) treatment is the standard of care for chronic hepatitis C patients. Some DAA regimens are highly effective and safe even for those with renal dysfunction/failure including those receiving HD. However, it remains unclear to what extent HD specialists gain knowledge about advances in anti-hepatitis C virus (HCV) treatment. To clarify the current situation and identify problems in the treatment of HD patients with chronic hepatitis C, we performed a questionnaire survey at 36 HD facilities between June 2016 and September 2017. In a total of 3418 HD patients, 179 (5.2%) were positive for anti-HCV antibody, and among these patients, 110/125 (88.0%) were positive for serum HCV RNA. Of the latter, only 42/110 (38.2%) patients received antiviral therapy. Moreover, HCV serotyping or genotyping was performed in 23/110 (20.9%) patients. In 26/49 (53.1%) of the remaining 68 untreated patients, "HD specialists do not know any HCV-specific treatments" and "HD specialists have no opportunity to consult with a hepatologist" were the reasons cited for the lack of anti-HCV treatment. This epidemiological study found that some HD patients with chronic hepatitis C had not yet received antiviral treatment despite the emergence of DAAs. To overcome such undesirable circumstances, medical cooperation between HD specialists and hepatologists should be required.
