Comparison of miRNA quantitation by Nanostring in serum and plasma samples.

Circulating microRNAs that are associated with specific diseases have garnered much attention for use in diagnostic assays. However, detection of disease-associated miRNA can be affected by several factors such as release of contaminating cellular miRNA during sample collection, variations due to amplification of transcript for detection, or controls used for normalization for accurate quantitation. We analyzed circulating miRNA in serum and plasma samples obtained concurrently from 28 patients, using a Nanostring quantitative assay platform.

Multicenter experience using simeprevir and sofosbuvir with or without ribavirin to treat hepatitis C genotype 1 in patients with cirrhosis.

Unlabelled: Interferon (IFN)-free regimens are needed to treat hepatitis C virus (HCV) infection. Combined simeprevir (SMV) and sofosbuvir (SOF) with or without ribavirin (RBV) results in high sustained virological response (SVR) rates along with minimal adverse events (AEs) in patients with hepatitis C genotype 1 (HCV GT1). The aim of this study was to report on the virological response, safety, and tolerability of SOF and SMV with or without RBV in compensated and decompensated patients with cirrhosis with HCV GT1 infection.

Multicenter experience using simeprevir and sofosbuvir with or without ribavirin to treat hepatitis C genotype 1 after liver transplant.

Unlabelled: Treatment with an all-oral interferon-free antiviral regimen using simeprevir and sofosbuvir with or without ribavirin (RBV) for 12 weeks resulted in high sustained virologic response (SVR) rates along with minimal adverse events in non-liver transplant (LT) patients with hepatitis C virus (HCV) genotype 1 infection. This is the first multicenter report on the efficacy, safety, and tolerability of this regimen in LT recipients. A total of 123 patients (76% male, 74% white, 60% genotype 1a, 30% METAVIR F3-F4, 4% decompensation, 11% cholestatic recurrence, 7% had kidney transplant, and 82% previously failed pegylated interferon/RBV-based regimens) received treatment and were followed for a median of 30 weeks (range 12-53 weeks).

Multicenter experience using telaprevir or boceprevir with peginterferon and ribavirin to treat hepatitis C genotype 1 after liver transplantation.

The safety, efficacy, and effect on immunosuppression levels of telaprevir (TVR) or boceprevir (BOC) in combination with peginterferon (PEG-IFN) and ribavirin (RBV) in recipients of liver transplantation (LT) with hepatitis C virus (HCV) genotype 1 have not been defined. We report our 3 centers' preliminary experiences with administering triple antiviral treatment protocols containing PEG-IFN, RBV, and TVR or BOC. Patients with biopsy-proven HCV recurrence (METAVIR grade ≥ 3 and/or stage ≥ 2) received TVR with PEG-IFN/RBV for 12 weeks and then PEG-IFN/RBV for 36 weeks or BOC with PEG-IFN/RBV for 44 weeks after 4 weeks of lead-in PEG-IFN/RBV.
