BACKGROUND & AIMS Excellent single-center outcomes of neoadjuvant chemoradiation and liver transplantation (LT) for unresectable perihilar cholangiocarcinoma caused the United Network of Organ Sharing (UNOS) to offer a standardized model of end-stage liver disease (MELD) exception for this disease. We analyzed data from multiple centers to determine the effectiveness of this treatment and the appropriateness of the MELD exception. METHODS We collected and analyzed data from 12 large-volume transplant centers in the US who met the inclusion criteria of treating three or more patients with perihilar cholangiocarcinoma using neoadjuvant therapy followed by liver transplantation from 1993–2010 (n=287 total patients). Center-specific protocols and medical charts were reviewed on-site. RESULTS The patients completed external radiation (99%), brachytherapy (75%), radio-sensitizing (98%), and/or maintenance chemotherapy (65%). Seventy-one patients dropped out before liver transplantation (rate of 11.5% in 3 months). Intent-to-treat survival was 68% and 53%, 2 and 5 years after therapy, respectively; post-transplantation, recurrence-free survival rates were 78% and 65%, respectively. Patients outside the UNOS criteria (those with tumor mass >3 cm, trans-peritoneal tumor biopsy, or metastatic disease) or with a prior malignancy had significantly shorter survival times (P<.001). There were no differences in outcomes among patients based on differences in operative staging or brachytherapy. Although most patients came from 1 center (n=193), the other 11 centers had similar survival times after therapy. CONCLUSION Patients with perihilar cholangiocarcinoma who were treated with neoadjuvant therapy followed by liver transplantation at 12 US centers had a 65% rate of recurrence-free survival after 5 years, demonstrating this therapy to be highly effective. An 11.5% dropout rate after 3.5 months of therapy indicates the appropriateness of the MELD exception. Rigorous selection is important for the continued success of this treatment.
BACKGROUND & AIMS The rate of readmission to the hospital 30 days after discharge (30-day readmission rate) is used as a quality measure for hospitalized patients, but it has not been studied adequately for patients with advanced liver disease. We investigated the incidence and factors that predict this rate and its relationship with mortality at 90 days. METHODS We analyzed data from patients with advanced liver disease who were hospitalized to an inpatient hepatology service at 2 large academic medical centers in 2008. Patients with elective admission and recipients of liver transplants were not included. During the study period, there were 447 patients and a total of 554 eligible admissions. Multivariate analyses were performed to identify variables associated with 30-day readmission and to examine its relationship with mortality at 90 days. RESULTS The 30-day readmission rate was 20%. After adjusting for multiple covariates, readmission within 30 days was associated independently with model for end-stage liver disease scores at discharge (odds ratio [OR], 1.06; 95% confidence interval [CI], 1.02–1.09; P = .002), the presence of diabetes (OR, 1.78; 95% CI, 1.07–2.95; P = .027), and male sex (OR, 1.73; 95% CI, 1.03–2.89; P = .038). After adjusting for age, sex, and model for end-stage liver disease score at discharge, the 90-day mortality rate was significantly higher among patients who were readmitted to the hospital within 30 days than those who were not (26.8% vs 9.8%; OR, 2.6; 95% CI, 1.36 –5.02; P = .004). CONCLUSIONS Patients with advanced liver disease frequently are readmitted to the hospital within 30 days after discharge; these patients have a higher 90-day mortality rate than those who are not readmitted in 30 days. These data might be used to develop strategies to reduce early readmission of hospitalized patients with cirrhosis.
Objective To compare long-term survival of living donor liver transplant (LDLT) at experienced transplant centers to outcomes of deceased donor liver transplant (DDLT) and identify key variables impacting patient and graft survival. Summary Background Data The Adult-to-Adult Living Donor Liver Transplantation Cohort Study (A2ALL) is a prospective multicenter NIH study comparing outcomes of LDLT and DDLT and associated risks. Methods Mortality and graft failure for 1427 liver recipients (963 LDLT) enrolled in A2ALL transplanted between 1/1/1998 and 1/31/2014 at 12 North American centers with median follow-up 6.7 years were analyzed using Kaplan-Meier and multivariable Cox models. Results Survival probability at 10 years was 70% for LDLT and 64% for DDLT. Unadjusted survival was higher with LDLT (HR=0.76, p=0.02) but attenuated after adjustment (HR=0.98, p=0.90) as LDLT recipients had lower mean MELD (15.5 vs 20.4) and fewer were transplanted from ICU, inpatient, on dialysis, ventilated, or with ascites. Post-transplant ICU days were less for LDLT. For all recipients female gender and primary sclerosing cholangitis were associated with improved survival, while dialysis and older recipient/donor age were associated with worse survival. Higher MELD score was associated with increased graft failure. Era of transplantation and type of donated lobe did not impact survival in LDLT. Conclusions LDLT provides significant long-term transplant benefit resulting in transplantation at a lower MELD score, decreased death on waitlist, and excellent post-transplant outcomes. Recipient diagnosis, disease severity, renal failure, and ages of recipient and donor should be considered in decision-making regarding timing of transplant and donor options.

Boceprevir and telaprevir, when added to pegylated interferon and ribavirin for the treatment of chronic hepatitis C virus infection, increase the rates of sustained virologic response in treatment naïve persons to approximately 70%. While these agents represent an important advance in the treatment of chronic hepatitis C virus, they present new treatment challenges to the Hepatology community. Boceprevir and telaprevir are both substrates and inhibitors of the hepatic enzyme cytochrome P450 3A and the drug transporter, P-glycoprotein, which predisposes these agents to many drug interactions. Identification and appropriate management of potential drug interactions with telaprevir and boceprevir is critical for optimizing therapeutic outcomes during hepatitis C treatment. This review highlights the pharmacologic characteristics and drug interaction potential of boceprevir and telaprevir and provides guidance on the management of drug interactions with these agents.
