Abstract
Background Liver retransplantation (reLT) has historically had inferior survival relative to primary liver transplant (LT). To improve outcomes after reLT, researchers have identified factors predicting overall (OS) and/or graft survival (GS) after reLT. This systematic review and random effects meta-analysis sought to summarize this literature to elucidate the strongest independent predictors of post-reLT. Methods A systematic review was conducted to identify manuscripts reporting factors affecting survival in multivariable Cox proportional hazards analyses. Papers with overlapping cohorts were excluded. Results All 25 included studies were retrospective, and 15 (60%) were single-center studies. Patients on pre-transplant ventilation (HR, 3.11; 95% CI, 1.56-6.20; p = 0.001) and with high serum creatinine (HR, 1.46; 95% CI, 1.15-1.87; p = 0.002) had the highest mortality risk after reLT. Recipient age, Model for End-Stage Liver Disease score, donor age, and cold ischemia time >12 h also conferred a significant risk of post-reLT death (all p < 0.05). Factors affecting GS included donor age and retransplant interval (the time between LT and reLT; both p < 0.05). OS is significantly higher when the retransplant interval is ≤7 days relative to 8-30 days (p = 0.04). Conclusions The meta-analysis was complicated by papers utilizing non-standardized cut-off values to group variables, which made between-study comparisons difficult. However, it did identify 7 variables that significantly impact survival after reLT, which could stimulate future research into improving post-reLT outcomes.

Differences Between Infectious Disease Events in First Liver Transplant Versus Retransplantation in the Swiss Transplant Cohort Study. Liver Transpl 2021; 27:1283-1290. [PMID: 33838077 DOI: 10.1002/lt.26068] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/11/2020] [Revised: 03/09/2021] [Accepted: 03/29/2021] [Indexed: 12/22/2022]
Abstract
Retransplantation after graft failure is increasingly performed, and inferior graft survival, patient survival, and quality of life has been reported. The role of infectious disease (ID) events in this less favorable outcome is unknown. We analyzed ID events after first liver transplantation (FLTpx) and retransplantation (reLTpx) in the Swiss Transplant Cohort Study. Clinical factors were compared after FLTpx and reLTpx, and survival analysis was applied to compare the time to ID events after FLTpx and after reLTpx, adjusted for age, sex, Model for End-Stage Liver Disease score, donor type, liver transplant type (whole versus split liver), and duration of transplant surgery. In total, 60 patients were included (65.0% male, median age of 56 years). Overall, 343 ID events were observed: 204 (59.5%) after the FLTpx and 139 (40.5%) after reLTpx. Bacterial infections were most frequent (193/343, 56.3%), followed by viral (43/343, 12.5%) and fungal (28/343, 8.2%) infections, with less infections by Candida spp. but more by Aspergillus spp. after reLTpx (P = 0.01). The most frequent infection site was bloodstream infection (86, 21.3%), followed by liver and biliary tract (83, 20.5%) and intraabdominal (63, 15.6%) infections. After reLTpx, more respiratory tract and surgical site infections were observed (P < 0.001). The time to first infection was shorter after FLTpx (adjusted hazard ratio [HR], 0.5; 95%-confidence interval [CI], 0.3-1.0; P = 0.04). Reduced hazards for ID events after reLTpx were also observed when modelling recurrent events (adjusted HR, 0.5; CI, 0.3-0.8; P = 0.003). The number of infections was comparable after FLTpx and reLTpx; however, differences regarding infection sites and fungal species were observed. Hazards were reduced for infection after reLTpx.

Retransplantation outcomes for hepatitis C in the United States before and after direct-acting antiviral introduction. Am J Transplant 2021; 21:1100-1112. [PMID: 32794649 DOI: 10.1111/ajt.16254] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2020] [Revised: 07/13/2020] [Accepted: 08/05/2020] [Indexed: 01/25/2023]
Abstract
The success of direct-acting antiviral (DAA) therapy has led to near-universal cure for patients chronically infected with hepatitis C virus (HCV) and improved post-liver transplant (LT) outcomes. We investigated the trends and outcomes of retransplantation in HCV and non-HCV patients before and after the introduction of DAA. Adult patients who underwent re-LT were identified in the Organ Procurement and Transplantation Network/United Network for Organ Sharing database. Multiorgan transplants and patients with >2 total LTs were excluded. Two eras were defined: pre-DAA (2009-2012) and post-DAA (2014-2017). A total of 2112 re-LT patients were eligible (HCV: n = 499 pre-DAA and n = 322 post-DAA; non-HCV: n = 547 pre-DAA and n = 744 post-DAA). HCV patients had both improved graft and patient survival after re-LT in the post-DAA era. One-year graft survival was 69.8% pre-DAA and 83.8% post-DAA (P < .001). One-year patient survival was 73.1% pre-DAA and 86.2% post-DAA (P < .001). Graft and patient survival was similar between eras for non-HCV patients. When adjusted, the post-DAA era represented an independent positive predictive factor for graft and patient survival (hazard ratio [HR]: 0.67; P = .005, and HR: 0.65; P = .004) only in HCV patients. The positive post-DAA era effect was observed only in HCV patients with first graft loss due to disease recurrence (HR: 0.31; P = .002, HR 0.32; P = .003, respectively). Among HCV patients, receiving a re-LT in the post-DAA era was associated with improved patient and graft survival.

Effects of the Mammalian Target of Rapamycin Inhibitor Everolimus on Hepatitis C Virus Replication In Vitro and In Vivo. Transplant Proc 2018; 49:1947-1955.

Abstract
BACKGROUND The influence of immunosuppressants on hepatitis C virus (HCV) re-infection after liver transplantation, particularly mammalian target of rapamycin inhibitors, remains unclear. The aim of our study was to analyze the influence of everolimus (EVR) on HCV replication activity in the context of underlying molecular mechanisms, with focus on the pro-myelocytic leukemia protein (PML). METHODS HCV viral load was recorded in 40 patients with post-transplant HCV re-infection before and 8 weeks after introduction of EVR. An HCV cell culture replicon system for genotype (GT) 1b, GT2b, and GT3a was used to compare the influence of EVR on HCV replication for the respective genotypes in vitro. Fluorescence-activated cell-sorting analysis was used to test for effects on cell proliferation. PML expression was silenced with the use of small hairpin RNA constructs, and PML expression was quantified by means of quantitative real-time polymerase chain reaction. RESULTS In patients with HCV, the viral load of GT1a and GT1b was hardly affected by EVR, whereas the viral load was reduced in patients with GT2a (P ≤ .0001) or GT3 infection (P ≤ .05). In vitro EVR impairs HCV replication activity of GT2a and GT3a up to 60% (P ≤ .0005), whereas in GT1b cells, HCV replication activity is increased by 50% (P ≤ .005). Replicon cell viability was not impaired. HCV replication activity is impaired in the absence of PML, which can be reversed by overexpression of PML isoforms. Furthermore, in the absence of PML, the effect of EVR on HCV replication activity is nearly abrogated. CONCLUSIONS The mammalian target of rapamycin inhibitor EVR influences HCV replication via PML. The herein presented results suggest a genotype-dependent benefit for an EVR-based immunosuppressive regimen in patients with GT2a or GT3 re-infection after liver transplantation.

Abstract
Hepatic retransplantation has been surgically challenging since the beginning of liver transplant. Outcomes have improved over time, but patient survival with retransplant continues to be significantly worse than that of primary transplant. Many studies have focused on factors to predict outcomes. Models have been developed to help predict risk, but the decision for retransplant must be a multidisciplinary transplant team decision. The question of "when is too much?" can be guided by recipient and donor factors but is an ethical decision that must be made by the liver transplant team.

Abstract
AIM: To identify risk factors associated with survival in patients retransplanted for hepatitis C virus (HCV) recurrence and to apply a survival score to this population.
METHODS: We retrospectively identified 108 patients retransplanted for HCV recurrence in eight European liver transplantation centers (seven in France, one in Spain). Data collection comprised clinical and laboratory variables, including virological and antiviral treatment data. We then analyzed the factors associated with survival in this population. A recently published score that predicts survival in retransplantation in patients with hepatitis C was applied. Because there are currently no uniform recommendations regarding selection of the best candidates for retransplantation in this setting, we also described the clinical characteristics of 164 patients not retransplanted, with F3, F4, or fibrosing cholestatic hepatitis (FCH) post-first graft presenting with hepatic decompensation.
RESULTS: Overall retransplantation patient survival rates were 55%, 47%, and 43% at 3, 5, and 10 years, respectively. Patients who were retransplanted for advanced cirrhosis had survival rates of 59%, 52%, and 49% at 3, 5, and 10 years, while those retransplanted for FCH had survival rates of 34%, 29%, and 11%, respectively. Under multivariate analysis, and adjusting for the center effect and the occurrence of FCH, factors associated with better survival after retransplantation were: negative HCV viremia before retransplantation, antiviral therapy after retransplantation, non-genotype 1, a Model for End-stage Liver Disease (MELD) score < 25 when replaced on the waiting list, and a retransplantation donor age < 60 years. Although the numbers were small, in the context of the new antivirals era, we showed that outcomes in patients who underwent retransplantation with undetectable HCV viremia did not depend on donor age and MELD score. The Andrés score was applied to 102 patients for whom all score variables were available, producing a mean score of 43.4 (SD = 6.6). Survival rates after the date of the first decompensation post-first liver transplantation (LT1) in the liver retransplantation (reLT) group (94 patients decompensated) at 3, 5, and 10 years were 62%, 59%, and 51%, respectively, among 78 retransplanted individuals with advanced cirrhosis, and 42%, 32%, and 16% among 16 retransplanted individuals with FCH. In the non-reLT group with hepatic decompensation, survival rates were 27%, 18%, and 9% at 3, 5, and 10 years, respectively (P < 0.0001). Compared with non-retransplanted patients, retransplanted patients were younger at LT1 (mean age 48 ± 8 years compared to 53 ± 9 years in the no reLT group, P < 0.0001), less likely to have human immunodeficiency virus (HIV) co-infection (4% vs 14% among no reLT patients, P = 0.005), more likely to have received corticosteroid bolus therapy after LT1 (25% in reLT vs 12% in the no reLT group, P = 0.01), and more likely to have presented with sustained virological response (SVR) after the first transplantation (20% in the reLT group vs 7% in the no reLT group, P = 0.028).
CONCLUSION: Antiviral therapy before and after retransplantation had a substantial impact on survival in the context of retransplantation for HCV recurrence, and with the new direct-acting antivirals now available, outcomes should be even better in the future.

Abstract
The first interferon-free regimens have been approved for the treatment of patients with chronic hepatitis C virus (HCV). In the liver transplant (LT) setting, these regimens are expected to have an important effect, because graft loss due to HCV recurrence is a serious problem after LT. The response to the hitherto conventional treatment with pegylated interferon and ribavirin is poor. The significantly better response rates achieved with boceprevir-based and telaprevir-based triple therapy have led to better graft and patient survival rates, but severe drug interactions with immunosuppressants limit the feasibility of this therapy for LT patients. With the approval of sofosbuvir in January 2014, of simeprevir in May 2014, and of daclatasvir in August 2014, three antiviral agents are now available and promise to be applicable without relevant adverse effects or negative interactions with immunosuppressants. Thus, 2014 marks the beginning of a new era of treatment options for HCV recurrence after LT. Although safety and efficacy studies of several interferon-free regimens for patients with HCV recurrence after LT have achieved good preliminary results, reports of clinical experiences with LT patients are scarce. The lack of randomized studies, the small number of enrolled and carefully selected patients, and the heterogeneity of these studies make the results questionable. Real-life experiences are eagerly awaited so that clinicians can estimate the usefulness and the pitfalls of these new regimens. Additionally, the high costs of these agents may limit their accessibility for many patients. The aim of this review is to summarize the current experience with and the expectations of the new direct-acting antiviral agents for LT patients.
