It has yet to be firmly established whether host IFNL3 (IL28B) genotype influences interferon responsiveness in patients with chronic hepatitis B. We investigated associations between single-nucleotide polymorphisms (SNPs) in the IFNL3 region and response to peginterferon alfa-2a in 701 patients enrolled in three large, randomized, international studies.
Approximately one-third of patients have durable responses after finite (48-week) treatment with peginterferon alfa-2a. The ability to identify patients likely to respond would be particularly useful in resource-limited settings.
HEV infection can lead to chronic hepatitis in immunosuppressed patients; extrahepatic manifestations are rarely seen. Here, we report a 13-year-old renal transplant patient with chronic hepatitis E and renal involvement. Ribavirin therapy led to temporary virus clearance and amelioration of kidney function. However, ribavirin therapy caused severe hyporegenerative anemia, which has so far only been reported in patients treated with a combination of ribavirin and interferon alpha.
Clinical studies evaluating the efficacy of daclatasvir (DCV) for treatment of chronic hepatitis C virus (HCV) genotype 4 (GT4) infection are scarce. This study aims to evaluate the efficacy and safety of DCV plus sofosbuvir (SOF) with or without ribavirin (RBV) for treatment of Egyptian patients infected with HCV GT4.
This study aimed to describe the real-world efficacy and safety of sofosbuvir (SOF) + ribavirin (RBV) for chronic hepatitis C, genotype 2.
The aim of this study was to evaluate the relationship between interleukin-21 (IL-21) and interleukin-21 receptor (IL-21R) polymorphisms and the response to peginterferon alfa (PEG-IFN α) therapy in HBeAg-positive chronic hepatitis B (CHB) patients.A total of 143 HBeAg-positive CHB patients treated for 48 weeks with PEG-IFN α and followed up for 24 weeks post-treatment were retrospectively evaluated. Genotypes analysis was performed for IL-21 polymorphisms rs907715, rs2221903, and IL-21R polymorphisms rs3...
Given the B helper function of follicular T helper (Tfh) cells and peripheral T helper (Tph) cells, we researched the roles of circulating PD-1CXCR5CD4 T cells and PD-1CXCR5CD4 T cells in the decrease in hepatitis B surface antigen (HBsAg) levels and hepatitis B virus (HBV) clearance in patients with chronic hepatitis B (CHB). In the present study, the frequencies of PD-1CXCR5CD4 T cells and PD-1CXCR5CD4 T cells measured by flow cytometry were significantly higher in patients with CHB than that in healthy c...
In Japan, there is a growing population of patients with chronic hepatitis C virus (HCV) infection who failed a direct-acting antiviral (DAA)-based regimen. In this Phase 3 study, we evaluated sofosbuvir-velpatasvir plus ribavirin in Japanese patients with genotype 1 or 2 HCV infection who previously received DAAs.
Pre-existence and appearance of resistance associated substitutions limit the efficacy of direct acting antivirals in treatment of hepatitis C. This is the first case report of an adolescent with chronic hepatitis C virus genotype 4 infection and cirrhosis who failed treatment with ombitasvir/paritaprevir/ritonavir and ribavirin. Resistance analysis showed baseline resistance associated substitutions M28V and Y93C and emergent D168H.
Treatment of chronic hepatitis C (CHC) has entered a new era since the introduction of direct-acting antiviral agents (DAAs). Numerous clinical trials have shown that treatment response as well as tolerability of DAAs are superior to those of conventional therapy with pegylated interferon and ribavirin. However, the results of clinical trials may not be directly applied to real-world practice. Therefore our study tried to investigate the effectiveness of various DAA regimens in Taiwanese patients with chron...
Hepatitis E virus (HEV) is a major cause of viral hepatitis worldwide. Owing to its feco oral transmission route, sporadic as well as epidemic outbreaks recurrently occur. No specific antiviral therapy is available against the disease caused by HEV. Broad spectrum antivirals such as ribavirin and interferon alfa are prescribed in severe and chronic HEV cases. However, the side effects, cost, and limitations of usage render the available treatment unsuitable for several categories of patients. We recently re...
In the past few years, a growing body of clinical evidence has highlighted the risk of vitamin D deficiency in patients with chronic hepatitis C and that vitamin D levels are associated with the course of hepatitis C virus (HCV) infection, adverse effects, and treatment response to peginterferon/ribavirin. Recently, studies have found that vitamin D status is related to drug resistance and increased risk of infection in patients with liver cirrhosis. Vitamin D-related gene polymorphisms have been found to e...
CD8CD28- regulatory T cells (Tregs) play important roles in chronic viral infections. Programmed death 1 (PD-1) is highly expressed on hepatitis C virus (HCV)-specific CTLs. However, little is known regarding the role of CD8CD28-PD1 T cells in hepatitis C. Herein, we found that the frequency of CD8CD28-PD1, but not CD8CD28-PD1- T cells, correlated with markers of chronic hepatitis C virus (HCV) infection and the response to treatment. Our results showed that CD8CD28-PD1 T cells were significantly elevated i...
According to death certificates, approximately 1800 persons die from hepatitis B annually in the United States (US); however, this figure may underestimate the true mortality from chronic hepatitis B (CHB).
Licensed for chronic hepatitis C treatment in 2011, the protease inhibitors (PIs) telaprevir (TVR) and boceprevir (BOC), which have high sustained viral responses (SVR), ushered a new era characterized by the development of direct-action drugs against the hepatitis C virus (HCV). The aim of this study was to analyze the effectiveness and safety of BOC and TVR administered with pegylated interferon and ribavirin and to share the experience of a Brazilian reference center.
Currently, there are no interferon-free treatments available for HCV-infected patients younger than 12 years of age. We evaluated the safety and effectiveness of the all-oral regimen ledipasvir-sofosbuvir ± ribavirin, in HCV-infected children aged 6 to
Genetic variants of inosine triphosphatase (ITPA) that confer reduced ITPase activity are associated with protection against ribavirin(RBV)-induced hemolytic anemia in peginterferon(IFN)/RBV-based treatment of hepatitis C virus (HCV). Patients with reduced ITPase activity showed improved treatment efficacy when treated with IFN/RBV. In addition, a genetic polymorphism near the IL28B gene is associated with an improved response to IFN/RBV treatment. RBV has been an important component of IFN-containing regim...
Pegylated interferon alfa-2a (PEG-IFN alfa-2a), which was developed to overcome the disadvantages of conventional formulations, is widely prescribed for hepatitis B or C virus infection. It is characterized by pharmacokinetic (PK) and pharmacodynamic (PD) properties much different from those of conventional forms. The present study developed a population PK-PD model of subcutaneous PEG-IFN α-2a in a Korean population. For PK, IFN alfa-2a concentrations were described by a one compartment model with first o...
Hepatitis C virus (HCV) treatment is aiming to cure and prevent the development, progression of fibrosis, and related complications. Interferon-based therapy was claimed to reduce or even reverse fibrosis. Although direct-acting agents have a better cure rate, we still lack the knowledge of their effect on fibrosis regression. We aim to assess fibrosis regression in direct-acting agents compared with interferon-based treatment regimens in the treatment of chronic HCV patients. The 204 chronic HCV patients w...
Chronic Hepatitis C virus infection (HCV) is associated with extrahepatic manifestations and an increased prevalence in cardiovascular disease. New direct acting antivirals (DAA) have revolutionized HCV treatment with high rates of sustained virological response (SVR). Recently it was demonstrated, that SVR reduces morbidity and overall mortality more than can be solely explained by hepatic effects, suggesting that treatment with DAA also affects cardiovascular disease. The aim of this pilot study was to id...
To assess chronic hepatitis B (CHB) patients' knowledge about hepatitis B and their experience of discrimination with regard to study, work, and daily life.
To study the epidemiology of chronic hepatitis C virus infection in Hong Kong and to estimate the service gap for achieving the WHO hepatitis elimination targets of attaining a diagnosis rate of 90%, treatment rate of 80% and 65% reduction in mortality rate by 2030.
