This randomized, prospective, multicenter trial compared the safety and efficacy of steroid-free immunosuppression (IS) to the safety and efficacy of 2 standard IS regimens in patients undergoing transplantation for hepatitis C virus (HCV) infection. The outcome measures were acute cellular rejection (ACR), severe HCV recurrence, and survival. The patients were randomized (1:1:2) to tacrolimus (TAC) and corticosteroids (arm 1; n ¼ 77), mycophenolate mofetil (MMF), TAC, and corticosteroids (arm 2; n ¼ 72), or MMF, TAC, and daclizumab induction with no corticosteroids (arm 3; n ¼ 146). In all, 295 HCV RNA-positive subjects were enrolled. At 2 years, there were no differences in ACR, HCV recurrence (biochemical evidence), patient survival, or graft survival rates. The side effects of IS did not differ, although there was a trend toward less diabetes in the steroid-free group. Liver biopsy samples revealed no significant differences in the proportions of patients in arms 1, 2, and 3 with advanced HCV recurrence (ie, an inflammation grade ! 3 and/or a fibrosis stage ! 2) in years 1 (48.2%, 50.4%, and 43.0%, respectively) and 2 (69.5%, 75.9%, and 68.1%, respectively). Although we have found that steroid-free IS is safe and effective for liver transplant recipients with chronic HCV, steroid sparing has no clear advantage in comparison with traditional IS.

To examine the impact of steroid withdrawal from the immunosuppression protocols in liver transplantation. The electronic databases Medline, Embase, Pubmed and the Cochrane Library were searched. Meta-analysis pooled the effects of outcomes of a total of 2590 patients enrolled into 21 randomized controlled trials (RCTs), using classic and modern meta-analytic methods. Meta-analysis of RCTs addressing patients transplanted for any indication showed no differences between corticosteroid-free immunosuppression and steroid-based protocols in most of the analyzed outcomes. More importantly, steroid-free cohorts appeared to benefit in terms of de novo diabetes mellitus development [R.R = 1.86 (1.43, 2.41)], Cytomegalovirus (CMV) infection [R.R = 1.47 (0.99, 2.17)], cholesterol levels [WMD = 19.71 (13.7, 25.7)], the number of patients that received the allocated treatment [O.R = 1.55 (1.17, 2.05)], severe acute rejection [R.R = 1.71 (1.14, 2.54)] and overall acute rejection [R.R = 1.31 (1.09, 1.58)] (when steroids were replaced in the steroid-free arm). Taking RCTs into account independently when steroids were not replaced, overall acute rejection was favoring the steroid-based arm [R.R = 0.75 (0.58, 0.98)]. Studies addressing exclusively transplanted HCV patients demonstrated a significant advantage of steroid-free protocols considering HCV recurrence [R.R = 1.15 (1.01, 1.13)], acute graft hepatitis [O.R = 3.15 (1.18, 8.40)], and treatment failure [O.R = 1.87 (1.33, 2.63)]. No unfavorable effects were observed after steroid withdrawal during short-term follow-up. On the contrary, significant advantages were documented.

Chronic hepatitis C represents a major clinical problem after liver transplantation, but factors influencing the recurrent disease have not been well characterized. We analyzed the clinical records of all the patients transplanted for hepatitis C virus (HW-related liver disease in our Center between 1991 and 1997. Eighty consecutive HCV-positive (+) patients (60 men, ages 28 to 64) survived more than 1 month after transplantation and were followed for a median of 45 months. Diagnosis of recurrent chronic hepatitis C was made in 38 patients (47.5%), of whom 22 had moderate/severe chronic hepatitis. Decompensated cirrhosis occurred in six patients (7.5%).

The purpose of this study was to evaluate the influence of a steroid-free immunosuppression on hepatitis C virus (HCV) recurrence. A total of 198 liver transplantation (LT) patients were randomized to receive immunosuppression with basiliximab and cyclosporine, either with prednisone (steroid [St] group) or without prednisone (no steroids [NoSt] group). The group of 89 HCV-infected patients was followed up with protocol biopsies for 2 years after LT. This group of HCV patients are the patients evaluated in the present study. The rejection rate was 19% (St: 21% versus NoSt: 17%; P ϭ 0.67). Patients in the St group had a slightly higher rate of bacterial infections (59% versus 38%; P ϭ 0.05). Almost all patients had histological HCVrecurrence (St: 39/40 (97%) versus NoSt: 40/41 (97%); P ϭ 1). The percentage of accumulated biopsies with grade 4 portal inflammation at 6 months, 1 year, and 2 years were, 23%, 49%, and 49% in the NoSt group, compared to 33%, 55%, and 69% in the St group, respectively (P ϭ 0.04 at 2 years). The percentage of accumulated biopsies with grade 3 or 4 fibrosis at 6 months, 1 year, and 2 years were 0%, 8%, and 22% in the NoSt group, compared to 8%, 19%, and 31% in the St group, respectively. Immunosuppression without steroids in HCV patients is safe, reduces bacterial infections and metabolic complications, and improves histological short-term evolution of HCV recurrence.

AIM: Steroids can increase hepatitis C virus (HCV) replication. After liver transplantation (LTx), steroids are commonly used for immunosuppression and acute rejection is usually treated by high steroid dosages. Steroids can worsen the outcome of recurrent HCV infection. Therefore, we evaluated the outcome of HCV infected liver recipients receiving initial steroid-free immunosuppression. METHODS: Thirty patients undergoing LTx received initial steroid-free immunosuppression. Indication for LTx included 7 patients with HCV related cirrhosis. Initial immunosuppression consisted of tacrolimus 2×0.05 mg/kg•d po and mycophenolate mofetil (MMF) 2×15 mg/kg•d po. The tacrolimus dosage was adjusted to trough levels in the target range of 10-15 µg/L during the first 3 mo and 5-10 µg/L thereafter. Manifestations of acute rejection were verified histologically. RESULTS: Patient and graft survival of 30 patients receiving initial steroid-free immunosuppression was 86% and 83% at 1 and 2 years. Acute rejection occurred in 8/30 patients, including 1 HCV infected recipient. All HCV-infected patients had HCV genotype II (1b). HCV seropositivity occurred within the first 4 mo after LTx. The virus load was not remarkably increased during the first year after LTx. Histologically, grafts had no severe recurrent hepatitis. CONCLUSION: From our experience, initial steroid-free immunosuppression does not increase the risk of acute rejection in HCV infected liver recipients. Furthermore, none of the HCV infected patients developed serious chronic liver diseases. It suggests that it may be beneficial to avoid steroids in this particular group of patients after LTx.

Backgrounds/Aims: Recurrent HCV-cirrhosis occurs in a substantial proportion of transplant recipients, with higher rates reported in patients who had recently received a transplant. Over-immunosuppression has been implicated in this more unfavorable outcome. To determine whether the implementation of specific measures aimed at reducing or avoiding negative predictive variables is associated with an improvement in the outcome of recurrent hepatitis C. Methods: Comparative study between a cohort of patients who had recently received a transplant (2001-2004) and a historical group of HCV-infected patients transplanted before the implementation of two simple measures (1999-2000): (i) use of dual initial immunosuppression (steroids D cyclosporine neoral or tacrolimus); (ii) slow steroid tapering (O6 months). Yearly biopsies were performed in these recipients, and only those with at least one protocol biopsy and those with cholestatic hepatitis (regardless of follow-up) were included in the study. End-point: rate of HCV-related severe disease (defined as bridging fibrosis, cirrhosis or fibrosing cholestatic hepatitis) within the first year post-transplantation. Results: Severe disease was significantly lower in this cohort compared to the historical group (26/90, 29% vs 25/52, 48%; pZ0.02). While other factors remained unchanged between the two cohorts, the proportion of patients on triplequadruple regimes and the number of boluses of methyl-prednisolone were lower and the duration of prednisone therapy longer in more patients who had recently received a transplant. Conclusions: Improving the outcome of recurrent hepatitis C may be achieved by reducing overall immunosuppression and avoiding abrupt variations in immunosuppression.
Steroid-Free Living-Donor Liver Transplantation in Adults

To examine the benefits of steroid avoidance in adult living donor liver transplantation, we compared the clinical courses of nine recipients receiving basiliximab or daclizumab and 13 historical patients who received steroids. The 1-year patient and graft survival and the incidence of acute cellular rejection were similar in both groups. The side effects of immunosuppression tended to be more frequent in the steroid group. Hepatitis C virus (HCV)-RNA levels measured early after transplantation remained suppressed in the steroid-free group. Steroid avoidance was beneficial in the recipients, as both steroid side effects and recurrence of HCV could be avoided.

Corticosteroid therapy contributes significant toxicity to liver transplantation. The safety and efficacy of early steroid withdrawal were determined in patients treated with either tacrolimus or microemulsion cyclosporin A (micro-CsA). The primary outcome was the proportion of patients who were steroid-free 1 year posttransplantation. From the seven Canadian adult liver transplant centers, 143 patients were randomly allocated oral treatment with either tacrolimus (n ؍ 71) or micro-CsA (n ؍ 72), together with corticosteroids and azathioprine. Eligibility criteria for steroid withdrawal included freedom from acute rejection for a minimum of 3 months, and prednisone <0.15 mg/kg/d. In eligible patients, the daily steroid dose was reduced by 2.5 mg each month until complete discontinuation was achieved. At 1 year after transplantation, 75% of the tacrolimus patients and 63% of the micro-CsA patients were steroid-free (P ؍ .20). Of all of the patients who became eligible for steroid withdrawal, steroid discontinuation was achieved in over 80%.
