Abstract
PURPOSE OF REVIEW Normothermic machine perfusion (NMP) is an emerging technology for liver preservation. Early clinical results demonstrate beneficial effects in reconditioning high-risk grafts. This review discusses the role of normothermic perfusion as a tool to assess graft viability and as a platform for graft intervention and modification. RECENT FINDINGS The potential benefits of NMP extend far beyond organ reconditioning. Recent pilot studies have identified clinically relevant viability criteria, which now require validation in large randomized control trials prior to implementation. Furthermore, preclinical studies demonstrate tremendous potential for NMP as a method to extend the preservation period, thus improving transplant logistics as well as serve as a platform for graft-targeted interventions to optimize the preservation period. SUMMARY NMP is a multifunctional tool with potential to transform liver preservation and the field of transplantation. Large clinical trials are necessary to optimize perfusion protocols, clarify indications for NMP therapy and justify use as the standard preservation modality.

Abstract
Chronic Hepatitis C relapse after liver transplantation can lead to graft failure
within a short time period. The high efficacy and good safety profile of
direct-acting antivirals has led to consensual recommendations for using
interferon-free treatment after liver transplantation. However, pegylated
interferon may still be required for genotype 3 non-responders. We treated a
liver graft recipient with grade 1 fibrosis in the biopsy with daclatasvir and
sofosbuvir for 12 weeks. He did not respond and progressed to grade 3 fibrosis.
Lacking other options, we obtained a sustained virological response with
pegylated interferon, ribavirin and sofosbuvir for 12 weeks. The combination of
pegylated interferon, ribavirin and sofosbuvir is a viable option after the
failure of direct acting antivirals in economically disadvantaged countries.

Abstract
BACKGROUND Treatment with direct-acting antiviral drugs in interferon-free regimens is currently recommended for viral hepatitis C recurrence after liver transplantation. There are limited data regarding its results in this population, and no optimal treatment scheme has yet been singled out. METHODS We report our real-world results in liver transplant (LT) recipients. All patients were hepatitis C virus (HCV) monoinfected and completed a 12-week treatment course, followed 12 weeks later by HCV polymerase chain reaction testing with 12 IU/mL sensibility. Liver fibrosis was graded with the use of biopsies taken <12 months before treatment and stratified as early (0-1) or moderate to advanced (2-4) according to the Metavir score. RESULTS Median postoperative time was 5.2 years. Genotype 3 was found in 66.7% of the sample. The following regimens were prescribed: daclatasvir-sofosbuvir with (n = 11) or without (n = 28) ribavirin. Genotypes 1 and 3 were evenly distributed between the regimens. Sustained virologic response (SVR) was obtained in 24 out of 28 patients (85.7%) who received daclatasvir-sofosbuvir and in all patients (100%) who received daclatasvir-sofosbuvir-ribavirin (global SVR 89.7%). All patients that failed treatment had genotype 3 HCV. Fibrosis was evaluated in 79.5% of the sample: 48.4% had early and 51.6% had moderate to advanced fibrosis, for which ribavirin was more commonly prescribed (P = .001). CONCLUSIONS The SVR rate in our LT recipients was similar to that previously reported in the literature. The addition of ribavirin to DAA treatment appears to be justified in this population.

Abstract
The use of immunosuppressants to reduce the likelihood of acute graft rejections is a cornerstone in the post-transplantation management of recipients. However, these agents were always associated with increased risk of deleterious effects such as infections vulnerability and comorbidities. The objective of this review is to discuss the impact of different immunosuppression strategies used in liver transplant recipients (LTRs) on the recurrence of hepatitis C virus (HCV) infections after transplantation. Traditionally, corticosteroids were a mainstay in immunosuppressive regimens in LTRs. Several trials have suggested early tapering of corticosteroids or steroid-free immunosuppression protocols to minimize metabolic complications and other accompanied adverse events. However, there is no consistent agreement on the apparent benefit of steroid-avoidance regimens on HCV recurrence. At present, calcineurin inhibitors alone or in combination with other immunosuppressants are the standard regimen for immunosuppression in LTRs. Although the use of mycophenolate mofetil and sirolimus were sometimes associated with a significantly lower risk of liver injury as a result of HCV recurrence, they were associated with an increased risk of acute graft rejection compared to calcineurin inhibitors. Consequently, reducing the incidence of HCV recurrence in LTRs could be at the expense of other potential complications. The appropriate selection of adequate immunosuppression could diminish the associated increased risk of HCV recurrence after liver transplantation. However, further clinical studies are still pivotal to establish the appropriate/optimal immunosuppressive therapies for HCV-positive LTRs.

Diagnostic Usefulness of APRI and FIB-4 for the Prediction of Liver Fibrosis After Liver Transplantation in Patients Infected with Hepatitis C Virus. Transplant Proc 2018; 50:1431-1436.

Abstract
BACKGROUND Aspartate transaminase-to-platelet ratio index (APRI) and fibrosis-4 (FIB-4) are well known as representative indirect serum biomarkers related to liver fibrosis. The usefulness of these markers for the diagnosis of liver fibrosis after liver transplantation (LT) in hepatitis C virus (HCV)-infected patients and the influence of splenectomy were investigated. METHODS From June 2003 to May 2014, 31 HCV-infected patients who underwent LT and postoperative follow-up liver biopsies were included in this study. The association between liver fibrosis and serum biomarkers and the influence of splenectomy on APRI and FIB-4 were also investigated. RESULTS A total of 195 biopsy specimens were collected, and liver fibrosis was identified as: F0, 59.7%; F1, 34.1%; and F2, 6.3%. Both APRI and FIB-4 were significantly higher in patients who showed F1 and F2 in liver biopsy specimen than F0 (P values, .009 and .022, respectively); sensitivity and specificity of APRI were, respectively, 63.4% and 66.7%, and those of FIB-4 were 57.7% and 69.6%. In 11 patients (35.5%) who underwent splenectomy at the time of LT, the cutoff values for APRI and FIB-4 were 0.61 and 1.41, which were significantly lower than the corresponding values (1.00 and 3.64) of patients without splenectomy. CONCLUSIONS APRI and FIB-4 could effectively estimate liver fibrosis after LT for HCV-related liver disease. For LT patients with splenectomy, APRI and FIB-4 were also useful to estimate liver fibrosis, but the standard values should be adjusted lower than those for patients without splenectomy.

Abstract
OBJECTIVE The aim of the study was to determine the clinical characteristics, frequency of opportunistic infections (OI), and the outcomes for liver transplant recipients with severe hepatitis C virus (HCV) recurrence. In addition, the objective was to evaluate HCV recurrence as a risk factor for developing an OI. METHODS We conducted a retrospective observational study recording all liver transplant recipients from July 1, 2003, to December 31, 2012. Patients with liver disease due to HCV were selected. Active surveillance of infections was conducted periodically, and patients were classified according to presence of severe HCV recurrence. RESULTS Three hundred seventy patients underwent liver transplantation because of chronic HCV. One hundred forty-seven patients presented severe recurrence (SR) (49%) and 50 (17%) of them had post-liver transplant cholestatic hepatitis C. Patients with SR presented OI, especially cytomegalovirus (CMV) infections and invasive fungal infections, more frequently than patients without SR (33% vs 13%; P < .001). From the diagnosis of SR to the presentation of OI, the median number of days was 169 (6-2083). Acute allograft rejection (OR 1.8 95% confidence interval [CI] 1.1-3.3) donor age ≥60 years (OR 2.9 95% CI 1.3-6.8), and SR (OR 2.8, 95% CI 1.6-5.1) were independently associated with the development of OI in liver transplant recipients. CONCLUSION A high index of suspicion of opportunistic infections must be maintained when faced with severe HCV recurrence in liver transplant recipients. Moreover, active surveillance against CMV infection and other prophylactic strategies against opportunistic infections should be considered.

Abstract
Caring for liver transplant patients suffering from chronic hepatitis C virus (HCV) infection is a challenging task for transplant surgeons and primary physicians alike. HCV is the leading cause of liver transplantation in the USA and comes with a myriad of complications that increase morbidity and mortality. This review focuses on patient follow-up, spanning from before the liver transplant occurs to the patient's long-term health. Pretransplant, both donor and recipient variables, must be carefully chosen to ensure optimal surgical success. Risk factors must be identified and HCV viral load must be reduced to a minimum. In addition to standard transplant complications, HCV patients suffer from additional problems, such as fibrosing cholestatic hepatitis and widespread viremia. Physicians must focus on the balance of immunosuppressive and antiviral medications, while considering possible side effects from these potent drugs. Over the years following surgery, physicians must identify any signs of failing liver health, as HCV-positive patients have an increased risk for cirrhosis and certain life-threatening malignancies.

Abstract
The availability of direct-acting antiviral (DAA) therapy has launched a new era in the management of chronic hepatitis C. Sofosbuvir, a uridine nucleotide analog that inhibits the hepatitis C RNA-dependent RNA polymerase, is the backbone of chronic hepatitis C therapy. Acting at the catalytic site of the polymerase, sofosbuvir is highly potent in suppressing viral replication and has a high genetic barrier to resistance. Sofosbuvir is effective across all hepatitis C genotypes, and is a mainstay of interferon-free combination therapy. In Phase II and III studies, genotype 1 patients who took sofosbuvir in combination with another DAA such as the NS3-4A protease inhibitor, simeprevir, or the NS5A replication complex inhibitors, ledipasvir or daclatasvir, achieved a sustained virologic response rate of over 90%. Harvoni®, a combination tablet of sofosbuvir and ledipasvir, dosed once daily is recommended for 24 weeks for treatment-experienced genotype 1 patients with cirrhosis, but 12 weeks of therapy is sufficient for all other populations. While genotype 2 (12 weeks or 16 weeks) and treatment-naïve genotype 3 patients (24 weeks) have excellent response rates with sofosbuvir and ribavirin, treatment-experienced cirrhotic genotype 3 patients may need the addition of another DAA such as daclatasvir. Sofosbuvir is efficacious in special populations such as HIV–hepatitis C virus-coinfected patients and liver transplant recipients and has already made a profound impact in these groups. Since it is renally eliminated, patients with advanced kidney disease or on dialysis must await dosing recommendations. Sofosbuvir-based regimens appear to be well tolerated with headache and fatigue being the most common side effects. The opportunity to cure patients with hepatitis C with sofosbuvir combination therapy is likely to change the future for our patients, particularly if the emphasis shifts to identifying those patients unaware that they are infected and providing affordable access to treatment.
