AbstractBackground and rationale. The REPLACE study (NCT01571583) investigated telaprevir-based triple therapy in patients who have recurrent genotype 1 hepatitis C virus (HCV) infection following ...liver transplantation and are on a stable immunosuppressant regimen of tacrolimus or cyclosporin A. Patients received telaprevir 750 mg 8-hourly with pegylated interferon 180 μg weekly and ribavirin 600 mg daily, followed by a further 36 weeks of pegylated interferon and ribavirin alone and 24 weeks of follow-up. Efficacy (sustained virological response SVR 12 weeks after last planned study dose), safety and tolerability of telaprevir throughout the study were assessed. Pharmacokinetics of telaprevir, tacrolimus and cyclosporin A were also examined. Results. In total, 74 patients were recruited. Overall, 72% (53/74; 95% CI: 59.9 to 81.5) of patients achieved SVR at 12 weeks following completion of treatment. Anticipated increases in plasma concentrations of tacrolimus and cyclosporin A occurred during telaprevir treatment and were successfully managed through immunosuppressant dose reduction and, for tacrolimus, reduced dosing frequency. Safety and tolerability of telaprevir-based triple therapy were generally comparable with previous data in non-transplant patients, although rates of reported anemia (55% 41/74) were higher. Elevated plasma creatinine (46% 34/74) was observed during REPLACE - consistent with the post-liver transplant population and the co-administered immunosuppressants. Conclusion. Telaprevir-based triple therapy in patients with recurrent genotype 1 HCV infection following liver transplantation produced high rates of SVR. Therapeutic concentrations of immunosuppressants were maintained successfully through dose modification during telaprevir treatment.

Hepatitis E and A are the major cause of acute hepatitis worldwide. Hepatitis E is also one of the major causes of chronic hepatitis in immunocompromised individuals. Both infections were initially ...attributed to developing countries because of poor sanitation and limited health access. However, it is now apparent that hepatitis E virus is endemic in high-income countries and is largely a zoonotic infection. Furthermore, recent hepatitis A outbreaks in high-risk populations have reinforced the necessity of scaling up the vaccination rates in these groups in developed countries.

AbstractIntroductionRecurrence of HCV infection in patients with chronic hepatitis C virus (HCV) at the time of liver transplantation is nearly universal and reduces the likelihood of graft and ...patient survival. Materials and methodsWe evaluated outcomes of 17 patients (16 with HCV genotype 1 and 1 with genotype 4) who received up to 12 or 24 weeks of ledipasvir/sofosbuvir plus ribavirin prior to or up to the time of liver transplant in the SOLAR-1 and SOLAR-2 trials. In all patients, HCV RNA was < 15 IU/mL prior to transplant. At screening, 6 patients were Child-Pugh-Turcotte (CPT) class B and 11 were CPT class C. Seven patients underwent transplant prior to completing assigned treatment, with 4 treated for < 12 weeks. The primary endpoint was posttransplant virologic response 12 weeks after transplant (pTVR12) in patients with HCV RNA < 15 IU/mL at their last measurement prior to transplant. ResultsOverall, 94% (16/17) achieved pTVR12. All who achieved pTVR12 received at least 11 weeks of treatment. The single patient who did not achieve pTVR12 discontinued study drug on day 21 and underwent liver transplant the following day. The patient had HCV RNA < 15 IU/mL at post-transplant week 2 but died 15 days post-transplant because of multi-organ failure and septic shock. ConclusionAmong a small population of HCV patients with decompensated cirrhosis, virologic response to ledipasvir / so-fosbuvir plus ribavirin prior to liver transplantation was maintained after transplantation, even if treatment was stopped early. Administration of ledipasvir / sofosbuvir plus ribavirin before liver transplant can prevent post-transplant HCV recurrence.
