Treatments with pegylated interferon/ribavirin (PEG-IFN/RBV) has been standard-of-care in patients with chronic hepatitis C virus (HCV) (CHC) infection and reimbursed in Taiwan. However, the actual cost-effectiveness remains unclear. We aimed to evaluate a real-world cost-effectiveness for CHC patients treated with PEG-IFN/RBV by using a clinical cohort with linkage to the National Health Insurance Research Database of Taiwan. The total and itemized medical-care expenses of outpatient visits of 117 treatment-naïve CHC patients with linkage to the two million sampling of the National Health Insurance Research Database were collected...

Single nucleotide polymorphisms (SNPs) within or near interferon lambda 4 (IFNL4) gene located upstream of IFNL3 are associated with response to anti-HCV therapy both in interferon (IFN)-based and IFN-free regimens. IFNL4 encodes IFNλ4, a newly discovered type III IFN, and its expression is controlled by rs368234815-TT/ΔG, which is in strong linkage disequilibrium (LD) with other tag SNPs within or near IFNL4 such as rs12979860 and rs8099917. Intrahepatic expression levels of IFN-stimulated genes (ISGs) affect the responsiveness to IFNα and are also associated with IFNL4 genotype...

Among patients with chronic kidney disease (CKD) in the United States, HCV infection causes significant morbidity and mortality and results in substantial healthcare costs. A once-daily oral regimen of elbasvir/grazoprevir (EBR/GZR) for 12 weeks was found to be a safe and efficacious treatment for HCV in patients with CKD. We evaluated the cost-effectiveness of EBR/GZR in treatment-naïve and treatment-experienced CKD patients compared with no treatment (NoTx) and pegylated interferon plus ribavirin (peg-IFN/RBV) using a computer-based model of the natural history of chronic HCV genotype 1 infection, CKD and liver disease...

A pressing need exists for improved therapeutic options for chronic hepatitis B (CHB). Pegylated-interferon-alpha (Peg-IFN-α) achieves sustained off-treatment responses in many cases because of its direct anti-viral effects and regulation of the immune response. However, non-responsiveness to Peg-IFN-α is frequent, and the mechanism is poorly understood. In this study, we found that the frequency and absolute number of NKp30(+) natural killer (NK) cells increased markedly, accompanied by enhanced CD107a and IFN-γ production, during Peg-IFN-α-2b monotherapy or combination therapy with adefovir dipivoxil in patients with CHB, especially in responders...

Death-associated protein kinase (DAPK) has been found to be induced by IFN, but its antiviral activity remains elusive. Therefore, we investigated whether DAPK plays a role in the pegylated IFN-α (peg-IFN-α)-induced antiviral activity against hepatitis C virus (HCV) replication. Primary human hepatocytes, Huh-7, and infectious HCV cell culture were used to study the relationship between peg-IFN-α and the DAPK-mammalian target of rapamycin (mTOR) pathways. The activation of DAPK and signaling pathways were determined using immunoblotting...

BACKGROUND: Interferon (IFN)-α has been commonly used as an antiviral drug worldwide; however, its short half-life in circulation due to its low molecular weight and sensitivity to proteases impacts its efficacy and patient compliance. RESULTS: In this study, we present an IgG1 Fc fusion strategy to improve the circulation half-life of IFN-α. Three different forms of IgG1 Fc fragments, including the wild type, aglycosylated homodimer and aglycosylated single chain, were each fused with IFN-α and designated as IFN-α/Fc-WT, IFN-α/Fc-MD, and IFN-α/Fc-SC, respectively...

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)...
