Abstract Nonalcoholic steatohepatitis (NASH) is a growing indication for liver transplant whether the primary or secondary cause of liver disease, and it is expected to be the leading indication in the years to come. Nonalcoholic steatohepatitis recurs after transplant but the impact of the recurrence on allograft and patient outcomes is unclear. A group of multidisciplinary transplant practice providers convened at the International Liver Transplantation Society NASH consensus conference with the purpose of determining the current knowledge and future directions for understanding the recurrence rates, risk and management of NASH in the transplant allograft. Specific questions relating to posttransplant NASH were proposed and reviewed in detail with recommendations on future actions to fill the knowledge gaps.

Purpose: To study the efficacy and safety of percutaneous cisplatin-epinephrine (CDDP-EPI) injectable gel in patients with localized unresectable hepatocellular carcinoma (HCC). Patients and Methods: Eligible patients had histologically proven HCC, no prior treatment except for surgery, and no more than three tumors (each measured ≤ 7 cm, total tumor volume ≤ 200 cm3). They were treated percutaneously under ultrasound or computed tomography (CT) guidance, with up to 10 mL of CDDP-EPI gel (1 mL contains 4 mg of CDDP and 0.1 mg of EPI) per treatment and four treatments in 6 weeks to a maximum of eight treatments. The primary end points were tumor response, defined by change of percentage of tumor necrosis according to CT criteria, and safety. Survival parameters were secondary end points. Results: From June 1997 to April 2000, 58 patients (median age, 65 years) entered the study. All patients were assessable for safety, and 51 were assessable for efficacy. The median number of treatments was four (range, one to eight treatments). Objective response rate was 53% (27 of 51 patients), including 16 complete and 11 partial responses. Of the 27 responders, 14 (52%) subsequently developed progressive disease, but in most of them (93%), a new tumor arose at untreated liver sites. Median survival was 27 months (range, 18.4 to 35.7 months). The 1-, 2-, and 3-year survival rates were 79%, 56%, and 14% respectively. The procedure was well tolerated with only minor side effects. Conclusion: Percutaneous local ablation with CDDP-EPI injectable gel can induce significant tumor necrosis and local control for localized unresectable HCC, and the treatment is well tolerated.

ABSTRACT The pharmacokinetics of an orally administered valine ester of ganciclovir (GCV), valganciclovir (VGC), were studied. These were compared to the pharmacokinetics of oral and intravenous GCV. Twenty-eight liver transplant recipients received, in an open-label random order with a 3- to 7-day washout, each of the following: 1 g of oral GCV three times a day; 450 mg of VGC per os (p.o.) once a day (q.d.); 900 mg of VGC p.o. q.d.; and 5 mg of intravenous (i.v.) GCV per kg of body weight q.d., given over 1 h. GCV and VGC concentrations were measured in blood over 24 h. One-sided equivalence testing was performed to test for noninferiority of 450 mg of VGC relative to oral GCV (two-sided 90% confidence interval [CI] > 80%) and nonsuperiority of 900 mg of VGC relative to i.v. GCV (two-sided 90% CI < 125%). The exposure of 450 mg of VGC (20.56 μg · h/ml) was found to be noninferior to that of oral GCV (20.15 μg · h/ml; 90% CI for relative bioavailability of 95 to 109%), and the exposure of 900 mg of VGC (42.69 μg · h/ml) was found to be nonsuperior to that of i.v. GCV (47.61 μg · h/ml; 90% CI = 83 to 97%). Oral VGC delivers systemic GCV exposure equivalent to that of standard oral GCV (at 450 mg) or i.v. GCV (at 900 mg of VGC). VGC has promise for effective CMV prophylaxis or treatment with once-daily oral dosing in transplant recipients.
