Effectiveness of first-wave protease inhibitors in hepatitis C virus genotype 1 infection: a multicenter study in Brazil
CONCLUSIONS: The effectiveness of hepatitis C virus triple therapy was lower than that reported in phase III clinical trials, possibly owing to the prioritized treatment of patients with advanced liver fibrosis. The high frequency of side effects and treatment interruptions observed supported the decision of the Brazilian authorities to suspend its use when safer and more effective drugs became available in 2015.

Quality of life in Brazilian patients with treated or untreated chronic hepatitis C.
CONCLUSIONS: Treatment can affect the subjective perception of patients regarding quality of life. Due to the complexity of the disease, each patient must be evaluated in multiple dimensions. Thus, the results may be useful for understanding the patient's perceptions during treatment, and it can also serve as a reference for care instructions.

Boceprevir and Telaprevir Effectiveness and Safety in A Brazilian Cohort of Chronic Hepatitis C Genotype 1 Patients: A Multicentric Longitudinal Study
Safety and efficacy of protease inhibitors for chronic hepatitis C (CHC) treatment were showed previously, however, the Brazilian population has been poorly represented in these investigations. Therefore, this study aimed to describe the effectiveness in terms of rapid virological response (RVR) and sustained virological response (SVR) of boceprevir and telaprevir-based regimens as well as safety of these two drugs in Brazil.

Validation of a questionnaire to monitor symptoms in HIV-infected patients during hepatitis C treatment.
CONCLUSIONS: The HCV-SI effectively differentiated among treatment regimens known to vary by side effect profiles and between patients with and without treatment discontinuation due to side effects. The HCV-SI may have value as a patient-reported outcome instrument predicting the risk of HCV treatment discontinuation. PMID: 28931406 [PubMed - in process] (Source: AIDS Research and Therapy)

Recent advancement of Direct-acting antiviral agents (DAAs) in Hepatitis C therapy.
Abstract Hepatitis C virus (HCV) infection is a major health burden worldwide. Approximately, 170-200 million individuals are chronically infected worldwide and a quarter of these patients are at increased risk of developing liver cirrhosis, hepatocellular carcinoma and even liver failure. A complete eradication of the virus is one of the most important treatment goal for antiviral research. In 2011, the first-generation protease inhibitors boceprevir (BOC) telaprevir (TVR) have been approved by FDA as the direct-acting antiviral agents. A number of promising new direct-acting antiviral agents (DAAs) have ...

Chemical genetics-based development of small molecules targeting hepatitis C virus.
Abstract Hepatitis C virus (HCV) infection is a major worldwide problem that has emerged as one of the most significant diseases affecting humans. There are currently no vaccines or efficient therapies without side effects, despite today's advanced medical technology. Currently, the common therapy for most patients (i.e. genotype 1) is combination of HCV-specific direct-acting antivirals (DAAs). Up to 2011, the standard of care (SOC) was a combination of peg-IFNα with ribavirin (RBV). After approval of NS3/4A protease inhibitor, SOC was peg-IFNα and RBV with either the first-generation DAAs boceprevir or...

Autoantibodies against “rods and rings”-related IMPDH2 in hepatitis C genotype 1 and DAA therapy in a “real life” cohort
AbstractAutoantibodies against inosine-5 ′-monophosphate-dehydrogenase-2 (IMPDH2; “rods and rings” pattern) develop in chronic hepatitis C (CHC) patients under treatment with peg-interferon (IFN) and ribavirin (RBV), an inhibitor of IMPDH2. We investigated the influence of the alternative therapy with direct-acting antivirals (DAA)/r ibavirin on anti-IMPDH2 autoantibody generation and the use of anti-IMPDH2 development as a marker for therapy outcome (sustained virologic response, SVR). We analyzed a “real life” cohort of 104 unselected CHC genotype 1 (GT1) patients treated with IFN/first-generation DAA/RBV prosp...

Dendritic cells activation is associated with sustained virological response to telaprevir treatment of HCV-infected patients.
In this study we evaluated the effect of telaprevir-based triple therapy on DC phenotype and function, and their possible association with treatment outcome. HCV+ patients eligible for telaprevir-based therapy were enrolled, and circulating DC frequency, phenotype, and function were evaluated by flow-cytometry. The antiviral activity of plasmacytoid DC was also tested. In SVR patients, myeloid DC frequency transiently decreased, and returned to baseline level when telaprevir was stopped. Moreover, an up-regulation of CD80 and CD86 on mDC was observed in SVR patients as well as an improvement of IFN-α production by plasmac...
