Liver transplantation is an established treatment option for end-stage liver failure. Now that newer, more potent immunosuppressants have been developed, glucocorticosteroids may no longer be needed and their removal may prevent adverse effects.

To assess the benefits and harms of glucocorticosteroid avoidance (excluding intra-operative use or treatment of acute rejection) or withdrawal versus glucocorticosteroid-containing immunosuppression following liver transplantation.

We searched the Cochrane Hepato-Biliary Group Controlled Trials Register, Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, Science Citation Index Expanded and Conference Proceedings Citation Index - Science, Literatura Americano e do Caribe em Ciencias da Saude (LILACS), World Health Organization International Clinical Trials Registry Platform, ClinicalTrials.gov, and The Transplant Library until May 2017.

Randomised clinical trials assessing glucocorticosteroid avoidance or withdrawal versus glucocorticosteroid-containing immunosuppression for liver transplanted people. Our inclusion criteria stated that participants should have received the same co-interventions. We included trials that assessed complete glucocorticosteroid avoidance (excluding intra-operative use or treatment of acute rejection) versus short-term glucocorticosteroids, as well as trials that assessed short-term glucocorticosteroids versus long-term glucocorticosteroids.

We used RevMan to conduct meta-analyses, calculating risk ratio (RR) for dichotomous variables and mean difference (MD) for continuous variables, both with 95% confidence intervals (CIs). We used a random-effects model and a fixed-effect model and reported both results where a discrepancy existed; otherwise we reported only the results from the fixed-effect model. We assessed the risk of systematic errors using 'Risk of bias' domains. We controlled for random errors by performing Trial Sequential Analysis. We presented our results in a 'Summary of findings' table.

We included 17 completed randomised clinical trials, but only 16 studies with 1347 participants provided data for the meta-analyses. Ten of the 16 trials assessed complete postoperative glucocorticosteroid avoidance (excluding intra-operative use or treatment of acute rejection) versus short-term glucocorticosteroids (782 participants) and six trials assessed short-term glucocorticosteroids versus long-term glucocorticosteroids (565 participants). One additional study assessed complete post-operative glucocorticosteroid avoidance but could only be incorporated into qualitative analysis of the results due to limited data published in an abstract. All trials were at high risk of bias. Only eight trials reported on the type of donor used. Overall, we found no statistically significant difference for mortality (RR 1.15, 95% CI 0.93 to 1.44; low-quality evidence), graft loss including death (RR 1.15, 95% CI 0.90 to 1.46; low-quality evidence), or infection (RR 0.88, 95% CI 0.73 to 1.05; very low-quality evidence) when glucocorticosteroid avoidance or withdrawal was compared with glucocorticosteroid-containing immunosuppression. Acute rejection and glucocorticosteroid-resistant rejection were statistically significantly more frequent when glucocorticosteroid avoidance or withdrawal was compared with glucocorticosteroid-containing immunosuppression (RR 1.33, 95% CI 1.08 to 1.64; low-quality evidence; and RR 2.14, 95% CI 1.13 to 4.02; very low-quality evidence). Diabetes mellitus and hypertension were statistically significantly less frequent when glucocorticosteroid avoidance or withdrawal was compared with glucocorticosteroid-containing immunosuppression (RR 0.81, 95% CI 0.66 to 0.99; low-quality evidence; and RR 0.76, 95% CI 0.65 to 0.90; low-quality evidence). We performed Trial Sequential Analysis for all outcomes. None of the outcomes crossed the monitoring boundaries or reached the required information size. Hence, we cannot exclude random errors from the results of the conventional meta-analyses.

Many of the benefits and harms of glucocorticosteroid avoidance or withdrawal remain uncertain because of the limited number of published randomised clinical trials, limited numbers of participants and outcomes, and high risk of bias in the trials. Glucocorticosteroid avoidance or withdrawal appears to reduce diabetes mellitus and hypertension whilst increasing acute rejection, glucocorticosteroid-resistant rejection, and renal impairment. We could identify no other benefits or harms of glucocorticosteroid avoidance or withdrawal. Glucocorticosteroid avoidance or withdrawal may be of benefit in selected patients, especially those at low risk of rejection and high risk of hypertension or diabetes mellitus. The optimal duration of glucocorticosteroid administration remains unclear. More randomised clinical trials assessing glucocorticosteroid avoidance or withdrawal are needed. These should be large, high-quality trials that minimise the risk of random and systematic error.

Hepatitis C virus (HCV) infection is the most common indication for liver transplantation worldwide; however, recurrence post transplant is almost universal and follows an accelerated course. Around 30% of patients develop aggressive HCV recurrence, leading to rapid fibrosis progression (RFP) and culminating in liver failure and either death or retransplantation. Despite many advances in our knowledge of clinical risks for HCV RFP, we are still unable to accurately predict those most at risk of adverse outcomes, and no clear consensus exists on the best approach to management. This review presents a critical overview of clinical factors shown to influence the course of HCV recurrence post transplant, with particular focus on recent data identifying the important role of metabolic factors, such as insulin resistance, in HCV recurrence. Emerging data for genetic markers of HCV recurrence and their usefulness for predicting adverse outcomes will also be explored.

Hepatitis C related liver failure and hepatocarcinoma are the most common indications for liver transplantation in Western countries. Recurrent hepatitis C infection of the allograft is universal and immediate following liver transplantation, being associated with accelerated progression to cirrhosis, graft loss and death. Graft and patient survival is reduced in liver transplant recipients with recurrent Hepatitis C virus (HCV) infection compared to HCV-negative recipients. Many variables may impact on recurrent HCV liver disease. Overall, excess immunosuppression is believed to be a key factor; however, no immunosuppressive regimen has been identified to be more beneficial or less harmful. Donor age limitations, exclusion of moderately to severely steatotic livers and minimization of ischemic times could be a potential strategy to minimize the severity of HCV disease in transplanted subjects. After transplantation, antiviral therapy based on pegylated IFN alpha with or without ribavirin is associated with far less results than that reported for immunocompetent HCV-infected patients. New findings in the field of immunotherapy and genomic medicine applied to this context are promising.

This prospective, non-randomized, multicenter cohort study analyzed the safety and efficacy of a steroid-free immunosuppressive (IS) protocol for hepatitis C virus (HCV)-positive living donor liver transplant (LDLT) recipients in Japan. Of 68 patients enrolled from 13 transplant centers, 56 fulfilled the inclusion/exclusion criteria; 27 were assigned the steroid-free IS protocol (Fr group) and 29 the traditional steroid-containing IS protocol (St group). Serum HCV RNA levels increased over time and were higher in the St group until postoperative day 90 (POD 14, p=0.013). Preemptive anti-HCV therapy was started in a higher percentage of recipients (59.3%) in the Fr group than in the St group (31.0%, p=0.031), mainly due to early HCV recurrence. The incidence of HCV recurrence at one yr was lower in the Fr group (22.2%) than in the St group (41.4%; p=0.066). The incidence of acute cellular rejection was similar between groups. New onset diabetes after transplant, cytomegalovirus infection, and renal dysfunction were significantly less frequent in the Fr group than in the St group (p=0.022, p<0.0001, p=0.012, respectively). The steroid-free IS protocol safely reduced postoperative morbidity and effectively suppressed both the HCV viral load in the early post-transplant period and HCV recurrence in HCV-positive LDLT recipients.

Avoidance of steroid therapy after solid-organ transplantation has become a major challenge. Corticosteroid (CS)-free maintenance immunosuppression not only eliminates the well-known adverse effects but also may improve long-term outcome.

To investigate whether a CS-free regimen of tacrolimus (Tac) in combination with daclizumab (Dac) induction therapy provides adequate coverage after orthotopic liver transplantation.

This 6-year, single-center, retrospective study included 25 liver transplant recipients randomized to a Tac/CS regimen (n = 18) vs a Tac/Dac regimen (n = 7) according to the protocol of the MASTER (Monoclonal Antibodies vs STERoids) Study.

No significant difference was observed in patient and graft survival between treatment arms: 94.4% in the Tac/CS group vs 71.4% in the Tac/Dac group. The incidence of biopsy-proved acute rejection episodes was 23.5% in the Tac/CS group vs 14.3% in the Tac/Dac group (P = NS). Total duration of hospitalization did not differ significantly between groups: 46.5 days in the Tac/CS group vs 73.9 days in the Tac/Dac group. Liver function as estimated using serum alanine aminotransferase and aspartate aminotransferase activity and bilirubin concentration, was not significantly different between the groups during 5 years posttransplantation. However, after 6 years, alanine aminotransferase activity was significantly greater in the Tac/Dac group compared with the Tac/CS group.

A CS-free regimen of Tac/Dac is as effective as Tac/Cs in achieving good patient and graft survival. However, no substantial benefits insofar as the safety of Tac/Dac therapy were evident during long-term follow-up.

Because of the markedly improved short-term results of liver transplantation (LT) and persistently high number of long-term complications, the attention of transplant physicians should be focused on minimizing immunosuppressive therapy as much as possible. Steroid-based immunosuppression is responsible for a substantial post-LT morbidity and mortality, hence, minimization of its use is of utmost importance to improve the quality of life of the successfully transplanted liver recipient. This literature review shows that LT can be performed safely with steroid-minimal immunosuppression without compromising graft and patient survival. The tendency in clinical practice is to move more and more from steroid withdrawal to steroid avoidance protocols.

Peripheral blood CD4+ adenosine triphosphate [ATP (ng/mL)] release [ImmuKnow Immune Cell Function Assay (ATP)] correlates to immunoreactivity. We hypothesized that ATP levels could provide insight into hepatitis C virus (HCV) infection and recurrent liver disease in liver transplantation (LT). We studied our center's LT cohort, in which ATP levels had been measured off protocol from February 2005 through July 2006. Of the 280 LTs performed since 1993, 114 (58.2%) fit the selection criteria, with a mean age of 49 +/- 10 years. LT (alone/combination) indications included HCV (58%), alcoholic liver disease (41%), hepatocellular carcinoma (16%), and other (33%). Four hundred seventy-seven ATP levels were obtained: 3 (1-17) per patient 25 months (4 days to 19 years) from the time from transplantation. Final diagnoses were normal allograft function (n = 166, 35%), recurrent disease (n = 199, 42%), septic event (n = 34, 7%), other (n = 51, 11%), and undetermined (n = 27, 6%). Two hundred eighty-one ATP levels were obtained [3 (1-18) per patient] in 66 HCV(+) patients. Forty-five (68%) developed biopsy-proven recurrent liver disease [188/281 (67%) ATP levels]. The median ATP level (ng/mL) was 162 (1-761); it was lower in HCV(+) patients (151 +/- 109) versus HCV(-) patients (211 +/- 139; P < 0.0001). ATP ranges in HCV(+) patients were stable from the time from transplantation. In HCV(-) patients, ATP ranges were initially high and eventually decreased to HCV(+) levels (P = 0.01). Immunosuppressant levels were low in 62% of HCV(-) patients versus 38% of HCV(+) patients (P = 0.04). In HCV(+) patients, ATP was lower in disease recurrence (139 +/- 97) versus none (181 +/- 141; P = 0.01) with similar immunosuppression, and ATP decreased with grade (P = 0.05) but not stage. Time from transplantation, aspartate aminotransferase/alanine aminotransferase >1, and low ATP were independently associated with recurrent HCV. In conclusion, after LT, global cellular immune function appears depressed at baseline in HCV(+) patients versus HCV(-) patients and more so in HCV(+) recurrent disease.

Hepatitis C (HCV)-related end-stage liver disease is the most common indication for liver transplantation. Safe expansion of the donor pool with improved rates of deceased donation and more widespread use of living and extended criteria donation are likely to decrease wait list mortality. In addition, improved antiviral treatments and a better understanding of the delicate balance between under- and over-immunosuppression in this population are needed. Finally, when recurrent advanced fibrosis occurs, the criteria for patient selection for retransplantation remain widely debated. This article reviews the literature on these topics and the work being done in each area to maximize outcomes in patients receiving transplants for HCV-related cirrhosis.

Due to the known high recurrence rate of hepatitis C virus (HCV) among orthotopic liver transplant (OLT) recipients who receive tacrolimus+corticosteroid maintenance, use of steroid-free induction was considered.

OLT recipients with HCV were randomized to receive tacrolimus+daclizumab (steroid-free) vs. tacrolimus+corticosteroids during 1999-2001 and then tacrolimus+mycophenolate mofetil (MMF)+daclizumab (steroid-free) vs. tacrolimus+MMF+corticosteroids during 2002-2005. Patients in the steroid-free arm of both periods received no steroids except for treating biopsy-proven rejection. Primary objective was to compare mean fibrosis stage at the 1-year protocol biopsy, between the steroid-free and corticosteroid arms, stratifying by period.

No noticeable differences in mean fibrosis stage between the two treatment arms, either averaging across periods (P=0.99) or during either period (P>0.35) were found. Occurrence of acute rejection during the first year was the only factor associated with a significantly increased fibrosis stage at 1 year (P=0.0003); stage > or =2 was seen in 63% (17 of 27) vs. 19% (8 of 43) of those with vs. without rejection. In addition, MMF use was associated with significantly fewer patients experiencing acute rejection during the first 6 and 12 months posttransplant (P=0.006 and 0.046). Regarding steroid-related side effects, posttransplant diabetes mellitus occurred in 10% vs. 45%, and wound infection in 6% vs. 31% of steroid-free vs. corticosteroid patients (P=0.003 and 0.01).

OLT recipients with HCV tolerated the steroid-free protocol with fewer side effects; however, its use had no apparent impact on hepatic fibrosis progression. Occurrence of acute rejection was strongly associated with increased hepatic fibrosis at 1 year, and MMF use appears to have significantly reduced the rejection rate.

Induction with the use of monoclonal antibodies targeting the alpha-chain (CD25) of the high-affinity IL2 receptor may avoid many of the adverse events associated with polyclonal antibodies and significantly impact on rejection-free long-term survival in orthotopic liver transplantation (OLT).

Forty-two consecutive deceased donor primary OLT were retrospectively analyzed. All patients received two 20-mg doses of basiliximab (days 0 and 4 after OLT) followed by tacrolimus (0.15 mg/kg/day; 10-15 ng/mL target trough levels), and steroids (methylprednisolone 1 g intraoperatively followed by tapering doses). Mycophenolate mofetil (MMF) 1 g every 12 h was added to the drug combination as needed. The mean follow-up period was 19.3 months (range: 4.8-35.9 months).

The average Model for End-Stage Liver Disease score was 26 (range: 15-40). A total of 39 patients (93%) remained rejection-free during follow-up with an actuarial rejection-free probability of 95% within 3 months. The actuarial patient and graft survival rate (Kaplan-Meier estimated) at 2 years was 93%. Twenty-five patients (60%) were completely off steroids within 3 months post-OLT (mean: 51.1 days, range: 10-90 days). By the 10th month post-OLT, 30/39 (77%) of the patients were completely off steroids. At last follow-up, 30/39 (77%) are on tacrolimus monotherapy with an average dose of 4 mg per day. Six patients (15%) are on double therapy, receiving a combination of tacrolimus and prednisone (two patients) or tacrolimus and MMF (two patients) or tacrolimus and mycophenolic acid (two patients). Only three patients (8%) are receiving triple therapy at last follow-up. Nine patients (21%) experienced at least one episode of infection. Only six (26%) of a total of 23 hepatitis C virus (HCV) recipients developed histology-proven HCV recurrence, with a mean onset of recurrence post-OLT of 3.2 months (range: 1.3-6.3 months). Of these six patients, two are presently undergoing treatment with interferon and ribavirin, one was treated and became HCV RNA negative, one was not treated, one declined treatment, and two died of HCV recurrence. None of the 42 study patients developed cytomegalovirus infection or posttransplant lymphoproliferative disease.

These preliminary data suggest that basiliximab, given in combination with a tacrolimus-based immunosuppressive regimen, is safe and associated with a low incidence of acute rejection and excellent short-term rejection-free graft and patient survival rate after OLT.

A controversy exists over whether the outcome of a hepatitis C virus (HCV)-infection-related liver transplant differs based on the calcineurin inhibitor (CNI) used. We have performed a systematic review and a subsequent meta-analysis evaluating tacrolimus (Tac)-based vs. cyclosporine A-based immunosuppression in HCV-infected liver transplant recipients. Searches were conducted to locate randomized controlled trials comparing Tac vs. cyclosporine A. Data on HCV liver transplant recipients were obtained, independently of whether the study was specifically designed for patients with this disease or not. A fixed effects model was used for statistical pooling of the relative risks (RR) for the different outcomes. A total of 5 articles (366 patients) fulfilled the inclusion criteria. Statistically significant differences between Tac-based vs. cyclosporine A-based therapies were not found for mortality (P = 0.11; RR = 0.72; 95% confidence interval [CI], 0.49-1.08), graft survival (P = 0.37; RR = 0.86; 95% CI, 0.61-1.21), biopsy-proven acute rejection (P = 0.65; RR = 0.91; 95% CI, 0.61-1.36), corticoresistant acute rejection (P = 0.26; RR = 2.25; 95% CI, 0.55-9.29), and fibrosing cholestatic hepatitis (P = 0.92; RR = 0.96; 95% CI, 0.41-2.26). In 1 study, no differences were detected regarding severe fibrosis at 1 yr. In conclusion, patient and graft survivals in HCV-positive liver transplant patients are similar independently of the CNI selected as basic immunosuppressant. Unfortunately, data on the severity of recurrence and effect on viremia are scarce. Well-designed randomized prospective studies are needed to determine whether there are differences between the 2 CNIs regarding these specific variables.

Hepatitis C virus (HCV) infection remains the most common cause of hepatic failure requiring orthotopic liver transplantation, and the disparity between the number of patients in need of liver replacement and the number of organs available continues to grow. Unfortunately, without viral eradication before transplantation, HCV recurrence is universal and is associated with poor graft and patient survival. Despite expansion of the donor pool and attempts to suppress HCV activity with various pretransplant and posttransplant antiviral therapies, many questions remain. This article reviews the literature regarding the evaluation of patients for transplantation, the antiviral therapies available in the peritransplant period, the immunosuppressive regimens, used, and the approach to patients with recurrent HCV infection.

Chronic infection with hepatitis C virus (HCV) is a growing problem worldwide, with up to 300 million individuals infected, and those with chronic infection are at risk for cirrhosis and hepatocellular carcinoma. HCV infection is the most common indication for liver transplantation in the United States and Europe. Unfortunately, although transplantation is effective for treating decompensated cirrhosis and limited hepatocellular carcinoma associated with hepatitis C, HCV reinfection is virtually the rule among transplant recipients. Reinfection of the graft is associated with more rapidly progressive disease, with a median time to cirrhosis of 8 to 10 yr. Unfortunately, treatment of chronic HCV in liver transplant recipients is suboptimal. Combination therapy with interferon (pegylated and nonpegylated forms) plus ribavirin appears to provide maximum benefits. Drug therapy is usually administered for recurrent disease. No prophylactic therapy is available. Preemptive regimens offer no distinctive advantages over treatments begun for recurrent disease. Overall, treatment is poorly tolerated, with frequent need for dose reductions, especially from cytopenias, and drug discontinuations in up to 50% of patients. Optimizing drug doses is important in maximizing sustained virological response rates. Future therapies may include ribavirin alternatives with lower rates of anemia, alternative interferons with lower rates of cytopenias, and new antiviral drugs that can be used alone or in combination with either interferon or ribavirin to enhance sustained virological response rates and improve tolerability. Liver Transpl 12:1192-1204, 2006. (c) 2006 AASLD.

Recurrent hepatitis C virus (HCV) disease is the leading cause of graft loss in liver transplant recipients with pre-transplant HCV infection. While natural history is variable, median time to recurrent cirrhosis is less than a decade. Factors contributing to risk of recurrence and rate of fibrosis progression are only partially known. Older donor age, treatment of acute rejection, cytomegalovirus infection and high pre-transplant viral load are most consistently linked with worse outcomes. Whether these factors can be modified to positively impact on HCV disease progression is unknown. The main therapeutic approach for patients with recurrent HCV disease has been the treatment with interferon and ribavirin (RBV) once recurrent disease is documented or progressive. Efficacy is lower than in nontransplant patients and tolerability, especially of RBV, is a major limitation. Stable or improved fibrosis scores are seen in the majority of sustained responders. Optimal dose, duration and timing of treatment have not been determined. Alternative strategies under study include pre-transplant treatment of decompensated cirrhotics, preemptive antiviral therapy started within weeks of transplantation and prophylactic therapy using HCV antibodies. Ongoing studies may establish a future role for alternative treatment approaches. Additionally, limited overall efficacy of interferon-based therapy in the transplant setting highlights the urgent need for new drug therapies.

Large (>or=45 transplants per year) North American liver transplant centres were surveyed regarding management of hepatitis C virus (HCV). A total of 25/41 (59%) and 28/48 (58%) of centres responded to the surveys in 1998 and 2003, respectively, with 17 centres participating in both surveys. HCV was the most common indication for transplantation. Use of protocol liver biopsies was higher in 2003 and 60% used them to monitor HCV disease. Fewer centres reported modifying primary immunosuppression (IMS) for HCV-positive (vs. non-HCV) patients in 2003 (26%) vs. 1998 (56%). IMS was most frequently tacrolimus-based, but mycophenolate mofetil use increased in 2003 (52% vs. 23% in 1998). In both years, approximately 40% treated allograft rejection differently in HCV-positive recipients, with less use of OKT3 in 2003. Combination anti-HCV therapy for 12 months or more was the treatment of choice and growth factor use was common (68%). HCV-positive recipients were considered candidates for retransplantation but HCV-specific criteria were used in decision-making. Practice of centres changed over time with an increase in HCV transplantation and use of protocol liver biopsies, and a trend towards lesser modification of IMS in HCV-positive recipients. We conclude that there is considerable variability in the management of HCV among transplant programs and over time.

Liver transplantation is a useful treatment for end stage liver disease of all aetiologies but recurrent disease presents an ongoing challenge, particularly for hepatitis C virus (HCV) where recurrence is almost universal. Immunosuppression is needed for all patients after transplantation and should be tailored to the individual patient, with particular problems being noted for those with HCV. The longer term effects of immunosuppression, particularly renal failure and the adverse effects of certain treatments on the liver graft, have become more important as survival improves and results are studied for longer periods after transplantation.
