Abstract
The rate of sustained virologic response (SVR) has increased in patients with chronic hepatitis C (CHC; genotype 1) since triple treatment with pegylated interferon (PEG-IFN), ribavirin (RBV) and telaprevir (TVR) was included in Japanese health insurance. However, side effects such as high-grade anemia and skin disorders means it is important to investigate the extent to which quality of life (QOL) is maintained during treatment. The impact on health-related (HR) QOL, as a result of TVR-based triple treatment was investigated long-term (48 weeks) in 34 patients (18 men, 16 women) following TVR-based triple treatment, using the 36-item short form health survey (SF-36). While scores for physical health were significantly lower during treatment, an improvement was seen in patients who showed complete response to treatment from 12 weeks following treatment (P<0.05). HRQOL improved significantly following completion of TVR-based triple treatment in these complete-responders, with higher scores compared with those prior to treatment. Anemia and skin symptoms appeared frequently during treatment and scores for physical health dropped. Particular care needs to be taken in regards to the management of side effects during TVR treatment. Further evaluations using the SF-36 may help in controlling doses to achieve SVR.
