UCLA and liver transplant

INTRODUCTION AND OBJECTIVES: Liver transplantation is the optimal treatment for patients with early hepatocellular carcinoma and cirrhosis. However, hepatocellular carcinoma recurs in approximately 15 % of individuals. This study aimed to assess the efficacy of predictive models for hepatocellular carcinoma recurrence after liver transplantation. PATIENTS AND METHODS: This retrospective study included 381 patients with HCC and evaluated the performance of the following models: R3-AFP score, alpha-fetoprotein (AFP) model, University of California, Los Angeles (UCLA) nomogram, Pre-Model of Recurrence after Liver Transplantation (MORAL), Post-MORAL, and Combo MORAL models, Risk Estimation of Tumor Recurrence (RETREAT) model and Platelet to Lymphocyte Ratio (PLR) model...

BACKGROUND: The molecular mechanisms underlying Fontan associated liver disease (FALD) remain largely unknown. We aimed to assess intrahepatic transcriptomic differences among patients with FALD according to the degree of liver fibrosis and clinical outcomes. METHODS: This retrospective cohort study included adults with the Fontan circulation at the Ahmanson/UCLA Adult Congenital Heart Disease Center. Clinical, laboratory, imaging and hemodynamic data prior to the liver biopsy were extracted from medical records...

Introduction: There is a critical need to accurately stratify liver transplant (LT) candidates' risk of post-LT mortality prior to LT to optimize patient selection and avoid futility. Here, we compare current pre -LT clinical risk scores with the recently developed Liver Immune Frailty Index (LIFI) for prediction of post -LT mortality. LIFI measures immune dysregulation based on pre-LT plasma HCV IgG, MMP3 and Fractalkine. LIFI accurately predicts post-LT mortality, with LIFI-low corresponding to 1.4% 1-year post-LT mortality compared with 58...

Pleural effusions are a common complication of orthotopic liver transplantation (OLT), and chronic post-OLT pleural effusions have been associated with worse outcomes. Furthermore, "trapped lung" (TL), defined as a restrictive fibrous visceral pleural peel preventing lung re-expansion, may have prognostic significance. We performed a retrospective analysis of adult OLT recipients over a 9-year period at UCLA Medical Center. Post-OLT patients with persistent pleural effusions, defined by the presence of pleural fluid requiring drainage one to 12 months after OLT, were included for analysis...

BACKGROUND: Vaccine preventable illnesses are important sources of morbidity, mortality, and increased healthcare costs in pediatric LT recipients. Our aim was to measure the seroprevalence of antibodies to measles and VZV in this population. METHODS: We conducted a retrospective chart review of 44 patients who received LT before age 18 at UCLA Mattel Children's Hospital from January 2008 to December 2017. RESULTS: Median age at transplantation was 2...

INTRODUCTION: Loneliness, "a subjective feeling of being isolated", is a strong predictor of adverse health. We characterized loneliness in patients with end-stage liver disease (ESLD) awaiting liver transplantation (LT). METHODS: We surveyed loneliness in ambulatory ESLD adults awaiting LT at 7 U.S. sites using the validated UCLA Three-Item Loneliness Scale, May2020-Jan2021; "lonely"=total ≥5. Liver Frailty Index (LFI) assessed frailty; "frail"=LFI≥4.4. Logistic regression associated loneliness and co-variables...

Liver transplant is an unreplaceable method for benign end-stage liver disease. The risk evaluation for the waiting list recipients and for post-transplant survival could provide practical indication for organ allocation. In recent years, there are two major kinds of evaluation scores. The first kind of evaluation scores is based on model for end-stage liver disease(MELD) score,including SOFT/P-SOFT score,UCLA-FRS score and BAR score. The other evaluation system is based on the concept of acute-on-chronic liver failure,including CLIF-C-ACLF score,TAM score,AARC-ACLF score and COSSH-ACLF score...

OBJECTIVES: Critically ill children frequently receive plasma and platelet transfusions. We sought to determine evidence-based recommendations, and when evidence was insufficient, we developed expert-based consensus statements about decision-making for plasma and platelet transfusions in critically ill pediatric patients. DESIGN: Systematic review and consensus conference series involving multidisciplinary international experts in hemostasis, and plasma/platelet transfusion in critically ill infants and children (Transfusion and Anemia EXpertise Initiative-Control/Avoidance of Bleeding [TAXI-CAB])...

Introduction: Due to the coronavirus disease 19 (COVID-19) pandemic, multiple measures have been implemented including social distancing and curfews. Both the disease and measures might cause stress, particularly in persons at risk, such as liver transplant (LT) recipients. Here, we evaluated the impact on psychosocial well-being of LT recipients. Methods: Seventy-nine LT recipients and 83 nontransplanted controls participated in this study. Questionnaires comprising the WHO-five well-being index (WHO-5), the University of California at Los Angeles (UCLA) Loneliness Scale, and the preliminary COVID-19 Pandemic Mental Health Questionnaire (CoPaQ) were distributed among them...

Purpose of the Review: This is a comprehensive update on failing Fontan physiology and the role of heart and combined heart and liver transplantation in the current era. Recent Findings: Single ventricle physiology encompasses a series of rare congenital cardiac abnormalities that are characterized by absence of or hypoplasia of one ventricle. This effectively results in a single ventricular pumping chamber. These abnormalities are rarely compatible with long-term survival if left without surgical palliation in the first few years of life...

BACKGROUND: Patients with end-stage liver disease and pretransplant Aspergillus colonization are problematic for determining liver transplant candidacy and timing of transplantation because of concerns for posttransplant invasive aspergillosis. METHODS: We performed a retrospective review of the medical and laboratory records of all adult patients (aged ≥18 y) who underwent liver transplantation with pretransplant Aspergillus colonization at the Ronald Reagan University of California, Los Angeles, Medical Center from January 1, 2010, to December 31, 2015...

BACKGROUND: Combined liver-kidney transplantation (CLKT) improves survival for liver transplant recipients with renal dysfunction; however, the tenuous perioperative hemodynamic and metabolic milieu in high acuity CLKT recipients increases delayed graft function and kidney allograft failure. We sought to analyze whether delayed KT through pumping would improve kidney outcomes following CLKT. METHODS: A retrospective analysis (UCLA [n=145], TMH [n=79]) was performed of all adults receiving CLKT at 2 high-volume transplant centers from February 2004 through January 2017, and recipients were analyzed for patient and allograft survival as well as renal outcomes following CLKT...

BACKGROUND: Intracranial hemorrhage (ICH) is a devastating complication. Although hypertension and thrombocytopenia are well-known risk factors for ICH in the general population, their roles in ICH after liver transplantation (LT) have not been well established. METHODS: We performed a retrospective study and hypothesized that intraoperative hypertension and thrombocytopenia were associated with posttransplant ICH. New onset of spontaneous hemorrhage in the central nervous system within 30 days after LT were identified by reviewing radiologic reports and medical records...

In a recent issue of Annals of Surgery, Halazun and colleagues present a new proposal for selection of patients with hepatocellular carcinoma (HCC) for liver transplantation2 . By reviewing patients who were transplanted at three different centers between 2001 and 2013, the authors analyzed predictors of outcomes. A total of 1540 patients with HCC were included in the analysis (680 at UCLA, and 388 and 382 at two NY centers), and the primary endpoint was 5-year recurrence-free survival (RFS).

BACKGROUND: As the population of patients with a Fontan palliation grows so does, the number of patients with cardiac failure necessitating orthotopic heart transplant (OHT) and combined heart-liver transplant (CHLT). There is recent evidence that current era cardiac transplant in Fontan patients has improved outcomes, but most studies have a preponderance of pediatrics patients in their cohorts. We examine our institutional experience with adult OHT and CHLT transplantation for failed Fontan physiology...

IMPORTANCE: Early allograft dysfunction (EAD) following a liver transplant (LT) unequivocally portends adverse graft and patient outcomes, but a widely accepted classification or grading system is lacking. OBJECTIVE: To develop a model for individualized risk estimation of graft failure after LT and then compare the model's prognostic performance with the existing binary EAD definition (bilirubin level of ≥10 mg/dL on postoperative day 7, international normalized ratio of ≥1...

BACKGROUND & AIMS: Primary non-function and ischaemic cholangiopathy are the most feared complications following donation-after-circulatory-death (DCD) liver transplantation. The aim of this study was to design a new score on risk assessment in liver-transplantation DCD based on donor-and-recipient parameters. METHODS: Using the UK national DCD database, a risk analysis was performed in adult recipients of DCD liver grafts in the UK between 2000 and 2015 (n = 1,153)...

Because liver fibrosis can be treated, it is important to diagnose liver fibrosis noninvasively and monitor response to treatment. Although ultrasound (grayscale and Doppler) can diagnose cirrhosis, it does so unreliably using morphologic and sonographic features and cannot diagnose the earlier, treatable stages of hepatic fibrosis. Transient elastography, ultrasound elastography with acoustic radiation force impulse, and MR elastography are modalities that can assess for hepatic fibrosis. Although all international organizations recommend ultrasound for screening for hepatocellular carcinoma, ultrasound is particularly limited for identifying hepatocellular carcinoma in patients with obesity, nonalcoholic fatty liver disease, and nodular cirrhotic livers...
