    ABSTRACT: Living donor liver transplantation is a procedure that has waned in its application over the past decade but remains a beneficial procedure for properly selected candidates. This review discusses some of the newer, relevant studies in the field, focusing on outcomes with hepatocellular carcinoma, ABO-incompatible transplant, and issues in donor complications and safety.

    ABSTRACT: NS3/4A protease inhibitors, boceprevir or telaprevir, combined with peginterferon and ribavirin was the standard treatment for HCV genotype 1 and remains the only available direct antiviral drug based therapy in some countries. Efficacy and safety data in liver transplant recipients are limited. This was a retrospective cohort study of 81 patients with genotype 1 HCV treated with boceprevir (10%) or telaprevir (90%) plus peginterferon and ribavirin at 6 US transplant centers (53% stage 3-4/4 fibrosis, 57% treatment experienced). The primary end point was undetectable HCV RNA 12 weeks after treatment completion (SVR12). The intent-to-treat SVR12 rate was 63% (51/81). Patients with an extended rapid virologic response, (undetectable HCV RNA at 4 and 12 weeks after starting boceprevir or telaprevir), had a higher rate of SVR12 than all other patients (85% vs. 15%, p<0.001). Adverse effects were common; 21% of patients experienced hemoglobin <8 g/dL and 57% required blood transfusions during the first 16 weeks. Twenty seven percent were hospitalized and 9% died; all were liver-related. The addition of boceprevir or telaprevir to peginterferon and ribavirin yields SVR12 of 63% in liver transplant recipients with genotype 1 recurrent HCV, despite a high prevalence of advanced fibrosis and prior non-response to peginterferon and ribavirin. Rapid virologic response predicted a high likelihood of SVR. Despite a doubling of SVR rates, poor tolerability and high rates of adverse events were frequent and pose barriers to its widespread application.

    ABSTRACT: Background and Objectives: Left ventricular hypertrophy (LVH) occurs in 12-30% of patients with cirrhosis; however its prognostic significance is not well studied. We assessed the association of LVH with survival in patients undergoing liver transplant (LT) evaluation.Methods: We performed a multicenter cohort study of patients undergoing evaluation for liver transplantation. LVH was defined using transthoracic echocardiography. The outcome of interest was all-cause mortality.Results: LVH was present in 138 (28%) out of 485 patients. Patients with LVH were older and more likely to be male and African American and were more likely to have hypertension. Amongst 345 patients who were not transplanted (212 declined & 133 waiting), 36/110 (33%) patients with LVH died compared to 57/235 (24%) patients without LVH (p=0.23). After LT, 8/28 (29%) patients with LVH died over 3 years compared to 9/112 (8%) patients without LVH (p<0.01). This finding was independent of conventional risk factors for LVH, and all deaths in those with LVH occurred within 9 months of LT. No clinical or demographic characteristics were associated with mortality among LVH patients.Conclusion: The presence of LVH is associated with an early increase in mortality following LT, independent of conventional risk factors for LVH. Further studies are needed to confirm these findings and identify factors associated with mortality following transplantation to improve outcomes. Liver Transpl , 2014. © 2014 AASLD.

    ABSTRACT: Patients with hepatopulmonary syndrome (HPS) are prioritized for liver transplantation (given exception points) due to their high pre- and post-transplant mortality. However, few studies have evaluated outcomes of these patients. We performed a retrospective cohort study using data submitted to United Network for Organ Sharing in a study of the effects of room air oxygenation on pre- and post-transplant outcomes of patients with HPS. We identified thresholds associated with post-transplant survival using cubic spline analysis, and compared overall survival times of patients with and without HPS. From 2002 through 2012, 973 patients on the liver transplant waitlist received HPS exception points. There was no association between oxygenation and waitlist mortality among patients with HPS exception points. Transplant recipients with more severe hypoxemia had increased risk of death after liver transplant. Rates of 3 y unadjusted post-transplant survival were 84% for patients with PaO2 of 44.1-54.0 mm Hg vs 68% for those with PaO2 ≤44.0 mm Hg. In multivariable Cox models, transplant recipients with an initial room-air PaO2≤44.0 mm Hg had significant increases in post-transplant mortality (hazard ratio, 1.58; 95% confidence interval [CI], 1.15-2.18), compared to those with a PaO2 of 44.1-54.0 mm Hg. Overall mortality was significantly lower among waitlist candidates with HPS exception points than those without (hazard ratio, 0.82; 95% CI, 0.70-0.96), possibly because patients with HPS have a reduced risk of pre-transplant mortality and similar rate of post-transplant survival. While there was no association between pre-transplant oxygenation and waitlist survival in patients with HPS MELD exception points, a pre-transplant room-air PaO2 ≤44.0 mm Hg was associated with increased post-transplant mortality. HPS MELD exception patients had lower overall mortality compared to others awaiting liver transplantation, suggesting that the appropriateness of the HPS exception policy should be reassessed.

    ABSTRACT: The treatment of steroid-resistant rejection (SRR) is associated with severe recurrent hepatitis C virus (HCV) infection after liver transplantation (LTx). After OKT3 was recently withdrawn from the market, thymoglobulin (TG) became the principal treatment for SRR. A retrospective analysis of 32 HCV patients who were treated for SRR with OKT3 (n=15) or TG (n=17) using yearly protocol liver biopsies. Mean follow-up was 4.3 years (OKT3) and 3.2 years (TG). We compared both groups for patient survival, graft loss, and severity of HCV recurrence, manifested as the mean stage of fibrosis (MSF). Patient survival at 1, 2, and 5 years after LTx was 80%, 73%, and 67% in the OKT3 group and 82%, 77%, and 64% in the TG group, respectively. At 2 years after LTx, the graft losses were 3 versus 4 in the OKT3 and TG groups, respectively. At years 1 and 2, the MSF in the OKT3 group was 1.9 and 2.3 versus 2.4 and 2.8 in the TG group, respectively. None of the differences between both groups was statistically significant. There was no significant difference in patient survival, graft loss, or severity of recurrent HCV, measured as MSF, between both groups.

    ABSTRACT: Orthotopic liver transplantation (OLT) is the preferred treatment for selected patients with hepatitis B virus (HBV)-related liver disease. This study aimed to (i) define long-term outcomes following OLT for HBV; (ii) to quantify the incidence of HBV recurrence (rHBV) as it relates to anti-HBV treatment; and (iii) to determine outcomes for specific patient subgroups. We performed a retrospective chart review of 738 patients undergoing OLT between 1985 and 2010 at seven US transplant centers and divided the patients into 3 eras, 1985-1994, 1995-2004, and 2005-2010, based on hepatitis B immunoglobulin and antiviral therapies. In Era 3, female gender (p = 0.002), recurrent hepatocellular cancer (p < 0.001), and retransplantation (p = 0.01) were significantly associated with worse survival on multivariate analysis. Survival at three yr was poor for all ethnicities in Era 1, but significantly improved for all except black Americans by Era 3. Era 2 data showed a continued increase in rHBV from five to 10 yr (16.6%, 26.2%). In conclusion, while OLT outcomes have improved because of combination antiviral and immunoglobulin therapy, women and black Americans may not have realized an equal benefit. The rate of rHBV is significant even 10 yr post-transplant with survival affected.

    ABSTRACT: Reinfection with hepatitis B virus (HBV) after liver transplantation (LT) may favor the recurrence of hepatocellular carcinoma (HCC), and combination therapy with hepatitis B immunoglobulin (HBIG) and nucleoside/nucleotide analogues may reduce HBV recurrence after LT. To test associations between HBV, HCC, and survival, we performed a retrospective chart review of patients undergoing LT for HBV between January 1985 and December 2010 at 7 US transplant centers. After we divided the patients into 3 eras based on evolving strategies in antiviral therapy (1985-1994, 1995-2004, and 2005-2010), we reviewed 16 variables to determine whether there were associations between survival and HCC recurrence. Seven hundred thirty-eight patients underwent transplantation for HBV, and 354 (47.7%) had concomitant HCC, which recurred in 58 patients (16.4%). Three-year survival was much better in era 3 versus era 1 (87% versus 40%, P = 0.001), and the incidence of HCC recurrence was lower (12% versus 29%, P = 0.009). The lungs were the most frequent first site of HCC recurrence, and they were followed by the liver. A multivariate analysis showed that HBV reinfection, HCC recurrence, and HBIG use were associated with worse survival (P < 0.001, P < 0.001, and P = 0.002, respectively); HCC recurrence and stage 3 HCC, among other factors, were associated with HBV reinfection (P < 0.001 and P = 0.004); and stage 3 HCC, vascular invasion of the explanted tumor, and post-LT chemotherapy were associated with HCC recurrence (P = 0.008, P < 0.001, and P < 0.001, respectively). Patients with HBV reinfection were 3.6 times more likely than patients without HBV to have HCC recurrence. These data suggest further study of attempts at LT for patients with HBV and HCC beyond the Milan criteria if their HBV is aggressively and successfully treated. Liver Transpl, 2013. © 2013 AASLD.

    ABSTRACT: BACKGROUND: Few studies have evaluated the accuracy of United Network for Organ Sharing (UNOS) or Scientific Registry of Transplant Recipients data among patients listed for liver transplantation. Of particular importance for transplant policy and practice is whether patients' outcomes are coded properly. METHODS: Using data from four transplant centers, we identified all liver transplant candidates removed from the waitlist from February 27, 2002 to July 24, 2010, with a specific focus the removal code of "other." RESULTS: Among nontransplanted patients at these centers, 2206 patients were removed for death or clinical deterioration. Of these, 8.6% (189 of 2206) were misclassified; they were assigned the UNOS removal code of "other." Among these 189 misclassified patients, 128 became medically unsuitable, 35 died, and 26 became too sick to transplant. Nearly one-half (46.8%) of misclassified patients were removed due to advanced hepatocellular carcinoma. Among true waitlist removals for death, only 35 of 1593 (2.2%) were misclassified. Conversely, of true removals for clinical deterioration, 154 of 612 (25.2%) were misclassified, with significant (P<0.001) center variation: 4.4% (Baylor), 8.0% (Georgetown), 32.6% (University of Pennsylvania), and 45.0% (Mount Sinai). Extrapolating these data to the entire United States, if "other" patients who truly died or clinically deteriorated were recoded appropriately, there would be an additional 2525 (95% confidence interval, 2046-3102) patients removed from the waitlist due to death (331) or clinical deterioration (2194) since 2002. DISCUSSION: A substantial proportion of patients truly removed from the waitlist for death or clinical deterioration were misclassified as "other." Thus, analyses using the UNOS or the Scientific Registry of Transplant Recipients database may underestimate the true proportion of patients removed from the waitlist for clinical deterioration.

    ABSTRACT: Renal dysfunction is a critical issue for liver transplant candidates and recipients. Acute and chronic nephrotoxicity, however, are the compromise for the potent immunosuppression provided by calcineurin inhibitors (CNIs). To maintain graft and patient survival afforded by CNIs while minimizing renal dysfunction in liver transplant patients, the reduction, delay, or elimination of CNIs in immunosuppression regimens is being implemented more frequently by clinicians. The void left by standard-dose CNIs is being filled by nonnephrotoxic immunosuppressants such as the mycophenolates and mammalian target of rapamycin (mTOR) inhibitors. Results of studies of renal-sparing regimens in liver transplant recipients have been inconsistent, which may be explained upon closer examination of several study-related factors including study design and duration of follow-up.

    ABSTRACT: BACKGROUND & AIMS: IL28B single nucleotide polymorphisms are strongly associated with spontaneous HCV clearance and treatment response in non-transplant populations. A DDX58 single nucleotide polymorphism is associated with the antiviral response of innate lymphocytes. We aimed to evaluate the associations of donor and recipient IL28B (rs12979860 and rs8099917) and DDX58 (rs10813831) genotypes with severity of HCV recurrence after liver transplantation. METHODS: In a case-control study of 523 liver transplantation recipients with HCV, we matched severe with mild recurrent HCV based on 2-year clinical and histologic follow-up. A total 440 liver transplantation recipients (severe, n=235; mild, n=205) with recipient DNA and 225 (severe, n=123; mild, n=102) with both recipient and donor DNA were analyzed. RESULTS: IL28B [rs12979860, non-CC (vs.CC) and rs8099917, non-TT (vs.TT)] in the recipient-only analysis had higher risk of severe recurrent HCV [OR 1.57 and 1.58, p<0.05]. However, for the 225 with donor and recipient DNA, IL28B rs12979860 CC (vs. non-CC) and rs8099917 TT (vs.non-TT) and DDX58 rs10813831 non-GG (vs. GG) was associated with more (not less) severe recurrent HCV. The greatest risk of severe recurrent HCV was for rs12979860 CC donors in non-CC recipients (OR 7.02, p<0.001,vs. non-CC donor/recipient) and for rs8099917 TT donors in non-TT recipients (OR 5.78, p=0.001, vs. non-TT donor/recipient). These associations persisted after controlling for donor age, donor race and donor risk index. CONCLUSIONS: IL28B and DDX58 single nucleotide polymorphisms that are favorable when present in the non-transplant setting or in the recipient are unfavorable when present in a donor liver graft.

    ABSTRACT: the A2ALL Study Group. Computerized assessment of competence-related abilities in living liver donors: the Adult-to-Adult Living Donor Liver Transplantation Cohort Study (A2ALL). Abstract: Background: Despite its importance, determination of competence to consent to organ donation varies widely based on local standards. We piloted a new tool to aid transplant centers in donor assessment. Methods: We assessed competence-related abilities among potential living liver donors (LDs) in the nine-center A2ALL study. Prospective LDs viewed an educational video and were queried to assess Understanding, Appreciation, Reasoning, and ability to express a Final Choice using the MacArthur Competence Assessment Tool for Clinical Research, adapted for computerized administration in LDs ("MacLiver"). Videotaped responses were scored by a clinical neuropsychologist (JF). Results: Ninety-three LDs were assessed. Mean (standard deviation; domain maximum) scores were as follows: Understanding: 18.1 (2.6; max = 22), Appreciation: 5.1 (1.0; max = 6), Reasoning: 3.1 (0.8; max = 4), and Final Choice: 3.8 (0.5; max = 4). Scores did not differ by demographics, relationship to the recipient, eligibility to donate, or eventual donation (p > 0.4). Higher education was associated with greater Understanding (p = 0.004) and Reasoning (p = 0.03). Conclusion: Standardized, computerized education with independent ratings of responses may (1) alert the clinical staff to potential donors who may not be competent to donate and (2) highlight areas needing further assessment and education, leading to better informed decision making.

    ABSTRACT: BACKGROUND: Two adverse effects of sirolimus are hypertriglyceridemia and hypercholesterolemia. These elevated levels often lead clinicians to discontinue the sirolimus from concerns of an increased cardiovascular disease (CVD) risk; however, evidence suggests that sirolimus might be cardioprotective. There are no published reports of sirolimus CVD in liver transplantation. METHODS: We reviewed all 1812 liver recipients who underwent transplantation from 1998 to 2010, identifying a cohort using sirolimus as part of the initial immunosuppression (SRL Cohort) and a control group of the remaining patients from this period where SRL was never given (Non-SRL Control). A prospectively maintained database identified all episodes of myocardial infarction (MI), congestive heart failure (CHF), abdominal aortic aneurysm (AAA), and cerebrovascular accident and tracked triglyceride, high-density and low-density lipoproteins, and total cholesterol levels. A Framingham Risk Model calculated the predicted 10-year risk of CVD for both groups. RESULTS: The SRL Cohort (n=406) is older, more predominantly male, with more pretransplantation hypertension and diabetes and posttransplantation hypertension compared to Non-SRL Controls (n=1005). The SRL Cohort has significantly higher triglyceride, low-density lipoprotein, and cholesterol levels at 6 months and 1 year. There is no difference in MI incidence in the SRL Cohort (1.0% vs. 1.2%) and no difference in AAA, cerebrovascular accident, and CHF. The Framingham Risk Model predicts that the SRL Cohort should have almost double the 10-year risk of CVD compared to the Non-SRL Control (11% vs. 6%). CONCLUSIONS: Sirolimus causes hypertriglyceridemia and hypercholesterolemia, but it does not increase the incidence of MI or other CVDs. Considering the SRL Cohort has more cardiac risk factors and nearly double 10-year predicted CVD risk, the fact that the CVD incidence is similar suggests that sirolimus is in fact cardioprotective.

    ABSTRACT: Coagulopathy, one of the cardinal features of advanced liver disease, is related to multiple factors including impaired synthetic function, thrombocytopenia, excessive fibrinolysis, platelet dysfunction, and disseminated intravascular coagulopathy. In the intensive care unit, management of coagulopathy may require treatment, particularly in the actively bleeding patient or in preparation for invasive procedures. This article reviews the background of coagulopathy in patients with end-stage liver disease and management options and comments on common clinical scenarios.

    ABSTRACT: Antibody-mediated rejection (AMR) is an uncommon, but challenging type of rejection after solid organ transplantation. We review three cases of AMR in ABO-compatible liver transplant recipients. These cases were characterized by severe acute rejection resistant to steroids and antithymocyte globulin, histologic evidence of plasma cell infiltrates, C4d positivity and high serum anti-HLA donor-specific antibodies. All three patients were treated with bortezomib, a proteasome inhibitor effective in depleting plasma cells. After treatment, all patients had improved or normal liver function tests, resolution of C4d deposition and significant decline in their HLA donor-specific antibodies.

    ABSTRACT: Because of the unrelenting donor shortage, utilization of all potential liver donors is essential. However, when utilizing marginal donors it is critical to precisely characterize the risks, inform recipients of those risks, and allocate these higher risk organs to appropriate candidates. Towards this goal, we need to determine the safety and potential consequences, if any, of utilizing hepatitis C (HCV) antibody-positive donors in HCV infected recipients. To further characterize HCV antibody-positive donors, we analyzed prospectively collected serum samples from HCV antibody-positive donors transplanted into HCV RNA-positive recipients from 5/1993 to 10/2008 for HCV viral load (Roche Cobas AmpliPrep/Cobas Taqman HCV Assay) and genotype (Siemens Versant 2.0 LiPA HCV 5' UTR/Core Assay). Seventeen of 32 (53%) HCV antibody-positive donors were RNA negative. Fifteen patients received an HCV RNA-positive donor and nine donor-recipient pairs had different genotypes or subtypes for analysis. When genotype 1 competed with a non-1 genotype, it was found in 5/6 recipients. In 2/3 cases of mismatched genotype 1 subtypes, genotype 1a dominated. Kaplan-Meier analysis of patient and graft survival and fibrosis progression did not reveal differences between patients who received an HCV antibody-positive donor that was viremic or aviremic. In conclusion, approximately half of HCV antibody-positive donors were aviremic. Viral dominance in viremic donor-recipient pairs seems virally determined.
