Hepatitis C recurrence after liver transplantation: Viral and histologic response to full-dose PEG-interferon and ribavirin.

Hepatitis C recurrence after liver transplantation (LT) is universal, and frequently leads to cirrhosis and death. The aim of our study was to assess the efficacy and safety of 48-weeks of full-dose peg-interferon-alpha-2a (n = 4) or alpha-2b (n = 51) plus ribavirin (>11 mg/kg/day) in a multicentric cohort of 55 patients > or =12 months after LT. All subjects had histologically proven HCV recurrence, excluding severe cholestatic recurrence. Mean age was 54.3 +/- 9.7, 77% male, 90.9% genotype 1, 32.7% cirrhotics. All but 5 patients received monotherapy with tacrolimus (54.5%), cyclosporine (30.7%) or mycophenolate mofetil (5.5%). The rates of end-of-treatment response and sustained virological response (SVR) were 66.7% and 43.6%, respectively. Low baseline HCV-RNA (p = 0.005) and a length from LT to therapy between 2-4 years (p = 0.011) were predictors of SVR. The lack of achieving a viral load decrease > or =1-log10 at week 4 and/or 2-log10 at week 12 was 100% predictive of failure. The most frequent side effects were neutropenia (76,4%), anemia (60%) and infectious complications (30.9%). Toxicity led to peg-interferon withdrawal in 16 (29%) subjects. In 15 patients with post-treatment biopsy, the histological activity index was significantly improved (p = 0.006), whereas fibrosis did not change (p = 0.14). Three patients died (cholangitis, hepatic artery thrombosis and lung cancer). In conclusion, HCV therapy after LT was very effective, although it led to a significant rate of toxicity.

Therapy of intractable pruritus with MARS.

INTRODUCTION: Pruritus is the most disabling symptom in patients with cholestatic liver diseases. Many drug therapies have been used for the treatment of these diseases, with different outcomes. The molecular adsorbent recirculating system (MARS) has been used in the treatment of intractable pruritus in cholestatic syndromes. We report our experience with MARS in 3 patients with intractable pruritus on the waiting list: 2 liver transplant recipients and a patient with primary biliary cirrhosis. PATIENTS AND RESULTS: Two middle-aged women and 1 middle-aged man, who were recipients of an orthotopic liver transplant for primary biliary cirrhosis, underwent three (n = 2) and two (n = 1) 6-hour sessions of MARS due to medically uncontrollable pruritus. All noted marked improvement of pruritus, with decreased bilirubin levels, but this improvement lasted only a few days in all cases. We observed no changes in transaminase or albumin levels, or prothrombin time. Complications included an episode of angina due to anemia caused by jugular catheter bleeding, and thrombocytopenia in all patients. CONCLUSIONS: MARS is an effective treatment for intractable pruritus in cholestatic liver diseases, although its beneficial effect is short. This extracorporeal liver device is safe, because most related adverse events are mild.

Results of liver transplantation in patients with previous portosystemic shunts.

INTRODUCTION: Although liver transplantation is performed successfully in some patients with previous portosystemic shunts (PSS), these surgical procedures have been considered a relative contraindication for orthotopic liver transplantation (OLT). We aimed to determine whether a previous PSS worsens the prognosis of patients who undergo OLT. PATIENTS AND METHODS: Between March 1986 and October 2003, 520 liver transplants were performed in 467 patients in our center. Thirteen patients had undergone a PSS before OLT. The types of PSS were: portocaval (n = 8), splenorenal (n = 3), mesocaval (n = 1), and portoatrial (n = 1). We compared patients with previous PSS (cases) and the three patients with an OLT immediately before each case (controls). We analyzed the following variables: age, Child-Pugh stage, pretransplant liver disease, surgical times, transfusion requirements, infections, intensive care unit (ICU) stay, postoperative evolution, and survival. RESULTS: Age, Child-Pugh stage, and pretransplant liver disease were similar in both groups. There were no statistical differences in age, surgical times, ischemia time, anhepatic phase, transfusion requirements, ICU stay, infections, or hospital stay. The postoperative course was similar in both groups. Long-term survival was 84.62% in cases versus 78.5% in controls. CONCLUSIONS: Previous PSS should not be considered a contraindication for liver transplantation, even though this group of patients involves a special surgical challenge.
