Liver retransplantation of patients with hepatitis C infection is associated with acceptable patient and graft survival

Infection with hepatitis C virus (HCV) is the leading cause of liver transplantation (LT), while liver retransplantation (RT) for HCV is controversial as a result of concerns over poor outcomes. We sought to compare patient and graft survival after RT in patients with and without HCV. We performed a retrospective chart review of all patients undergoing RT at our center between February 1998 and April 2004. Indications for RT, HCV status, patient, and donor characteristics, laboratory values, and hospitalization status at RT were collected. A total of 108 patients (48 HCV and 60 non‐HCV) underwent RT during the study period, with mean post‐RT follow‐up of 1,096 days (range, 0‐2,888 days). Grafts from donors aged >60 years were used less frequently in HCV patients at RT (6%) compared with LT (47%), P < 0.001. There was no difference between HCV vs. non‐HCV patients in 1‐ and 3‐year patient survival (respectively, 79% vs. 63%, and 71% vs. 63%) and graft survival (respectively, 67% vs. 66%, and 59% vs. 56%). Post‐RT mortality and graft failure in HCV patients occurred within the first year in 89% of patients, and 83% were unrelated to HCV recurrence. We conclude that patients should not be excluded from consideration for retransplantation solely on the basis of a diagnosis of HCV. Liver Transpl 13:1717–1727, 2007.

Preexisting atrial fibrillation and cardiac complications after liver transplantation

Atrial fibrillation (AF) is the most common cardiac arrhythmia, and it is associated with increased cardiovascular morbidity and all‐cause mortality. Our aim was to determine the impact of preexisting AF on patients undergoing liver transplantation (LT). A retrospective case‐control study was performed. Records from patients who underwent LT between January 2005 and December 2008 at Mayo Clinic Florida were reviewed. Patients with preexisting AF were identified and matched to patients who did not have a diagnosis of AF. Thirty‐two of 717 LT recipients (4.5%) had AF before LT. These patients were compared to a control group of 63 LT recipients. Pre‐LT left ventricular hypertrophy (P = 0.03), a history of congestive heart failure (P = 0.04), and a history of stroke or transient ischemic attack (P = 0.03) were significantly more prevalent in patients with AF versus controls. Intraoperative adverse cardiac events (P = 0.02) and AF‐related adverse postoperative events (P < 0.001) were more common in the recipients with known AF. Six patients with paroxysmal AF (19%) developed chronic/persistent AF postoperatively. Graft survival and patient survival were similar in the groups. Although patients with AF had a higher incidence of intraoperative cardiac events, a higher cardiovascular morbidity rate, and a complicated postoperative course, this did not affect overall graft and patient survival.

Liver Transplantation in Patients With Atrial Fibrillation

In this study we described survival and incidence of perioperative and postoperative complications in liver transplant recipients with known atrial fibrillation. A total number of 717 patients underwent liver transplantation between January 2005 and December 2008 at our institution. In this population, preoperative paroxysmal or chronic-persistent atrial fibrillation was diagnosed in 32 patients (4.5%). Of these, 12 patients died during follow-up and 4 patients required liver retransplantation. Perioperative cardiac complications occurred in 10 patients (31%) resulting in 3 cardiac-related deaths. Median patient survival was 1613 days (range, 22-2492) and median graft survival was 1524 days (range, 10-2492). Twenty patients are still alive with a median survival of 1861 days (range, 1189-2492) after liver transplantation.

Predictors and impacts of hospital readmissions following liver transplantation.

While liver transplantation is the definitive therapy for end stage liver disease, it remains a major procedure, with many potential complications. Hospital readmissions after the initial hospitalization for liver transplantation can be associated with adverse outcomes, increased cost, and resource utilization. Our aim was to define the incidence and reasons for hospital readmission after liver transplant and the impact of readmissions on patient outcomes. We retrospectively analyzed 30- and 90-day readmission rates and indications in patients who underwent liver transplant at a large-volume transplant center over a 3-year period. Four hundred seventy-nine adult patients underwent their first liver transplant during the study period. The 30-day readmission rate was 29.6%. Recipient and donor age, etiology of liver disease, biological Model for End-Stage Liver Disease score, and cold ischemia time were similar between patients who were readmitted within 30 days and those who were not readmitted. Readmissions occurred in 25% of patients who were hospitalized prior to liver transplant compared to 30% who were admitted for liver transplant. The most common indications for readmission were infection, severe abdominal pain, and biliary complications. Early discharge from hospital (fewer than 7 days after liver transplant), was not associated with readmission; however, a prolonged hospital stay after liver transplant was associated with an increased risk of readmission (p = 0.04). In conclusion, patients who undergo liver transplant have a high rate of readmission. In our cohort, readmissions were unrelated to pre-existing recipient or donor factors, but were associated with a longer hospital stay after liver transplant.While liver transplantation is the definitive therapy for end stage liver disease, it remains a major procedure, with many potential complications.

Reversible non-ischaemic cardiomyopathy and left ventricular dysfunction after liver transplantation: A single-centre experience

Non‐ischaemic cardiomyopathy (NIC) is an early complication of liver transplantation (LT). Our aims were to define the prevalence, associated clinical factors, and prognosis of this condition.

Intra-operative predictors of postoperative Takotsubo syndrome in liver transplant recipients—An exploratory case-control study

Takotsubo syndrome (TTS), also known as Takotsubo cardiomyopathy or stress‐induced cardiomyopathy, has been described following a variety of surgeries and disease states. The relationship between intra‐operative anesthesia management and the development of this syndrome has never been fully elucidated.

Dual hepatitis virus infections in liver transplant: case report and a review of the literature

Abstract:  Background:  Liver transplantation (LT) using grafts from anti‐HBVcore antibody‐positive (anti‐HBVcAB+) donors carry risk for development of hepatitis B virus (HBV) infection. The long‐term course of hepatitis C virus (HCV) patients receiving anti‐HBVcAB+ grafts is poorly understood.

Liver transplantation for hepatocellular carcinoma: Impact of wait time at a single center

INTRODUCTION AND AIM Liver transplantation (LT) provides durable survival for hepatocellular carcinoma (HCC). However, there is continuing debate concerning the impact of wait time and acceptable tumor burden on outcomes after LT. We sought to review outcomes of LT for HCC at a single, large U.S. center, examining the influence of wait time on post-LT outcomes. MATERIAL AND METHODS We reviewed LT for HCC at Mayo Clinic in Florida from 1/1/2003 until 6/30/2014. Follow up was updated through 8/1/ 2015. RESULTS From 2003-2014, 978 patients were referred for management of HCC. 376 patients were transplanted for presumed HCC within Milan criteria, and the results of these 376 cases were analyzed. The median diagnosis to LT time was 183 days (8 - 4,337), and median transplant list wait time was 62 days (0 - 1815). There was no statistical difference in recurrence-free or overall survival for those with wait time of less than or greater than 180 days from diagnosis of HCC to LT. The most important predictor of long term survival after LT was HCC recurrence (HR: 18.61, p < 0.001). Recurrences of HCC as well as survival were predicted by factors related to tumor biology, including histopathological grade, vascular invasion, and pre-LT serum alpha-fetoprotein levels. Disease recurrence occurred in 13%. The overall 5-year patient survival was 65.8%, while the probability of 5-year recurrence-free survival was 62.2%. CONCLUSIONS In this large, single-center experience with long-term data, factors of tumor biology, but not a longer wait time, were associated with recurrence-free and overall survival.

Palliative Care in Cirrhosis

The families and patients with end-stage liver disease (ESLD) confront physical and emotional challenges that are not frequently addressed by health-care providers. Palliative care emphasizes the assessment, anticipation, and alleviation of suffering in patients dying from the complications of cirrhosis in a holistic, patient-centered and family-focused manner. This chapter reviews the application of palliative care principles to patients with ESLD and the management of specific complications in the terminally ill patient.
