In HCV<sup>+</sup>(F4) individuals, nearly all CD8<sup>+</sup> T-cell subsets had an elevated proportion of perforin<sup>+</sup> cells while naïve cells had increased proportions of IFN-γ<sup>+</sup> and CD107<sup>+</sup> cells.
A total of 346 chronic hepatitis C (CHC) patients who finished the 48-week pegylated interferon-alpha and ribavirin (PEG IFN-α/RBV) treatment were enrolled in this study.
DAAs with or without IFN and RBV in the standard recommended 12 or 24-week treatment regimens are effective, well tolerated, and may be safely extended to elderly patients infected with chronic hepatitis C.
A Markov model simulated chronic hepatitis C (CHC) treatment interventions with IFN-based and IFN-free regimens at stage of fibrosis ≥F3, ≥F2 or regardless of fibrosis stage, and treatment either with the least or the most expensive combination.
After multivariate analyses the independent positive predictors for SVR after treatment for chronic hepatitis C with Peg-IFN and RBV were: absence of an AIDS-defining illness (p=0.001), HCV viral load lower than 600,000IU/mL at the onset of treatment (p=0.003), higher liver enzyme levels (p=0.039) at baseline, infection with genotypes 2 or 3 (p=0.003), and no transient treatment interruption (p=0.001).
Hepatic steatosis is a risk factor for both liver disease progression and an impaired response to interferon alpha (IFN-α)-based combination therapy in chronic hepatitis C virus (HCV) infection.
Cytopenia during interferon-based (IFN-based) therapy for chronic hepatitis C (CHC) often necessitates reduction of doses of drugs and premature withdrawal from therapy resulting in poor response to treatment.
Single nucleotide polymorphisms (SNPs) near IL28B (IFNλ3) are strongly associated with treatment response to IFNα therapy in chronic hepatitis C (CHC) patients.
This study tested whether differential expression of an important ISG with antiviral properties, tripartite motif 22 (TRIM22), correlates with a response to Peg-IFNα-2a/RBV combination therapy in treatment-naive patients with chronic hepatitis C. A total of 32 patients with chronic hepatitis C were enrolled in this study and received standard Peg-IFNα-2a/RBV combination therapy.
The occurrence of anti-IFN antibodies is associated with non-response to PEG-IFN in chronic hepatitis C. This study investigated the association between anti-IFN antibodies and response to PEG-IFN in CHB.
It is concluded that the combination of ARFI at cut off of 1.4 m/sec and IL28B may be useful for patients with chronic hepatitis C with genotype 1 treated with peg-IFN/ribavirin combination therapy.
A reduction of miR-122 expression has been suggested to be associated with responsiveness to IFN-based therapy in patients with chronic hepatitis C. Several independent genome-wide association studies reported a strong association between IFNL3 polymorphism and responsiveness to IFN-based therapy.
Randomized clinical trials and non-randomized clinical studies comparing PEG-IFN-α2a with PEG-IFN-α2b in association with ribavirin in adult patients with chronic hepatitis C were included.
To determine the SVR rate in patients ≥ 60 years with genotype 1 chronic hepatitis C treated with Peg-IFN and ribavirin, and to identify risk factors related to treatment response in this specific group of patients.Material and methods.
We intended to compare the efficacy and safety of PEG-IFN alfa-2a with those of PEG-IFN alfa-2b in Korean patients with chronic hepatitis C virus (HCV).
VDR gene polymorphisms are independently related to the response to Peg-IFN+RBV therapy in chronic hepatitis C and could be used as complementary biomarkers of response when included in a prediction algorithm in association with demographic, virologic, biochemical and genetic traits.
