Abstract
Daclatasvir (DCV) plus asunaprevir (ASV) treatment, an oral therapy for chronic hepatitis C virus (HCV) genotype 1b infection, can achieve a high sustained viral response (SVR) rate within a 24-week treatment period. A 55-year-old Japanese female with cirrhosis and null response for peginterferon plus ribavirin therapy received DCV plus ASV therapy, but she reported a slight fever beginning on treatment day 4. The fever increased to >38.0 °C beginning on treatment day 15 and could not be controlled with antipyretics; thus, the treatment was discontinued on day 17. Although the patient was still positive for HCV RNA 6 days after treatment discontinuation, she achieved an SVR at week 24 after treatment cessation. In some patients with HCV genotype 1b infection, an SVR can be achieved with short-term DCV plus ASV treatment, and HCV RNA positivity at the end of treatment does not always indicate virological failure.
