TLDR
Sofosbuvir plus ribavirin for 12 weeks may be effective in previously untreated patients with HCV genotype 1, 2, or 3 infection, and the rate of sustained virologic response 24 weeks after therapy is reported.Abstract:
BACKGROUND The standard treatment for hepatitis C virus (HCV) infection is interferon, which is administered subcutaneously and can have troublesome side effects. We evaluated so fos bu vir, an oral nucleotide inhibitor of HCV polymerase, in interferon-sparing and interferon-free regimens for the treatment of HCV infection. METHODSread more

TL;DR: Hemoglobin levels of < 10.5 g/dL prior to DAA treatment did not affect the virological response in renal patients but was associated with increased serum creatinine among KTx and those with CKD.

TL;DR: The emergence of RASs is a growing issue in the setting of current treatment with DAAs and should be consider in patients with therapeutic failure and in the cases of retreatment.

Sofosbuvir plus simeprevir for the treatment of genotype 1 chronic hepatitis C: a review of evidence.
TL;DR: The SOF/SIM combination exhibits efficacy and tolerability profiles that are similar to those of the other available interferon-free combinations used for non-cirrhotic genotypes 1b patients, but for patients with advanced cirrhosis or genotype 1a, this approach cannot be considered a routine treatment option due to the unsatisfactory results.

TL;DR: The new generation of AAD for the treatment of hepatitisC will lead to higher response rates in all subtypes of patients with lower complexity regimens and better tolerated.

TL;DR: It is reported that a genetic polymorphism near the IL28B gene, encoding interferon-λ-3 (IFN-α-2a) is associated with an approximately twofold change in response to treatment, both among patients of European ancestry and African-Americans.

TL;DR: Phosphoramidate prodrugs of the 5'-phosphate derivative of the β-d- 2'-deoxy-2'-α-fluoro-2-β-C-methyluridine nucleoside showed significant potency in the HCV subgenomic replicon assay and produced high levels of triphosphates 6 in primary hepatocytes and in the livers of rats, dogs, and monkeys when administered in vivo.

TL;DR: This preliminary study involving patients with chronic HCV genotype 1 infection who had not had a response to prior therapy showed that a sustained virologic response can be achieved with two direct-acting antiviral agents only.

TL;DR: Naturally occurring dominant STAT‐C resistance mutations are common in treatment‐naïve patients infected with HCV genotype 1, and their influence on treatment outcome should be characterized to evaluate possible benefits of drug resistance testing for individual tailoring of drug combinations when treatment options are limited due to previous nonresponse to peginterferon and ribavirin.
