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). The median time from LT to treatment was 32 months (range 2-317 months). Tacrolimus was the primary immunosuppression in 91% of patients. Minimal immunosuppression dose adjustments were required. An SVR 12 weeks after treatment completion (SVR12) was achieved in 90% of patients (95% confidence interval 84%-96%). In patients with genotype 1a infection, the SVR12 rate was significantly lower in those with METAVIR F3-F4 (71%) compared to those with F0-F2 (91%). Half of the patients achieved undetected HCV RNA at treatment week 4, and their SVR12 rate was significantly higher (96%) compared to those with detectable HCV RNA (83%). Treatment was very well tolerated with mild degrees of adverse events, except for one death possibly due to drug-induced lung injury. In the 25 patients who received RBV, 72% developed anemia requiring intervention. Conclusion: An all-oral interferon-free antiviral regimen using simeprevir and sofosbuvir with or without RBV for 12 weeks was very well tolerated and resulted in excellent SVR12 rates in LT recipients with HCV genotype 1 infection. (HEPATOLOGY 2015;61:1880-1886 H epatitis C viral (HCV) infection is the leading indication for liver transplant (LT) worldwide. Recurrence of HCV is universal among recipients with viremia at the time of transplant and occurs immediately after LT. 1,2 Although the clinical course of HCV recurrence is variable, severe histological recurrence is the most common cause of graft loss and death, which accounts for approximately 60% of graft losses and nearly 50% of deaths by 10 years after LT. 3,4 Liver allograft and recipient survival can be substantially improved with successful eradication of HCV. 5,6 Treatment with pegylated interferon (Peg-IFN) and ribavirin (RBV) was not effective and poorly tolerated in the post-LT setting, with reported sustained virologic response (SVR) rates ranging 24%-45% for patients with HCV genotype 1. 7,8 The combination of direct-acting antiviral agents, in the form of a firstgeneration protease inhibitor (PI), telaprevir or boceprevir, with Peg-IFN and RBV improved SVR rates to

PVT is frequently seen in patients with end stage liver disease with prevalence of 13 %. Hypercoagulable disorder was detected in 5 % of the patients screened. Careful use of anticoagulation is safe and effective in patients with PVT.

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. Patients treated with standardized clinical protocol utilizing SMV1SOF with or without RBV at three transplant centers were retrospectively reviewed. A total of 119 patients (61% male, 87% white, 69% subtype 1a, 30% Child-Pugh-Turcott [CPT]-B liver cirrhosis [LC], and 82% were treatment experienced) received treatment and were followed for a median of 38 weeks (range, 12-58). Sustained virological response (SVR) at week 12 (SVR12) was achieved in 78% (92 of 118) of patients (95% confidence interval: 69-85). Lower pretreatment Model for End Stage Liver Disease (MELD) score was a predictor of SVR12 (P 5 0.018). Baseline viral load, previous treatment status, RBV use, or GT1 subtype did not impact SVR 12. The majority of patients with SVR12 showed stability or improvement in MELD score. Treatment was very well tolerated with mild degrees of AEs. Conclusions: The regimen of SMV1SOF with or without RBV for 12 weeks was very well tolerated and resulted in high SVR12 rates (78%) in HCV GT1 patients with LC. SVR12 was inversely related to pretreatment MELD. SVR12 had favorable short-term impact on MELD score. Long-term impact on disease stability is yet to be determined. Longer treatment duration or the use of different regimen may still be needed in this population. (HEPATOLOGY 2015;62:1004-1012 A pproximately 3.4-4.9 million Americans are chronically infected with hepatitis C virus (HCV) and are at risk of developing cirrhosis, hepatocellular carcinoma (HCC), or both. Both decision modeling studies and U.S. veterans national studies estimated that 18%-25% of HCV-infected patients will have cirrhosis at time of diagnosis. That estimate will most likely reach a peak of 45% in 2020, leading to a progressive increase in the rates of hepatic decompensation and HCC in the next two decades.1 As a result of this, HCV infection is the leading indication for liver transplantation (LT) worldwide.
