Disease progression of side-branch intraductal papillary mucinous neoplasms following solid organ transplant.

Background: Branch-duct intraductal papillary mucinous neoplasms (BD-IPMNs) are becoming more prevalent with advanced medical imaging and account for most of pancreatic cystic neoplasms (PCNs). Most incidental lesions should be surveyed, with resection reserved for specific, high-risk cases. Solid organ transplantation candidates may be high risk of resection before transplant and will require systemic immunosuppression after transplant, which has been theorized to alter the natural history of the IPMN.

The Impact of Biliary Injury on the Recurrence of Biliary Cancer and Benign Disease after Liver Transplantation: Risk Factors and Mechanisms.

Liver transplantation is known to generate significant inflammation in the entire organ based on the metabolic profile and the tissue's ability to recover from the ischemia-reperfusion injury (IRI). This cascade contributes to post-transplant complications, affecting both the synthetic liver function (immediate) and the scar development in the biliary tree. The new occurrence of biliary strictures, and the recurrence of malignant and benign liver diseases, such as cholangiocarcinoma (CCA) and primary sclerosing cholangitis (PSC), are direct consequences linked to this inflammation.

Intensive locoregional therapy before liver transplantation for colorectal cancer liver metastasis: A novel pretransplant protocol.

We describe a novel pre-liver transplant (LT) approach in colorectal liver metastasis, allowing for improved monitoring of tumor biology and reduction of disease burden before committing a patient to transplantation. Patients undergoing LT for colorectal liver metastasis at Cleveland Clinic were included. The described protocol involves intensive locoregional therapy with systemic chemotherapy, aiming to reach minimal disease burden revealed by positron emission tomography scan and carcinoembryonic Ag.

The impact of normothermic machine perfusion and acuity circles on waitlist time, mortality, and cost in liver transplantation: A multicenter experience.

Ex situ normothermic machine perfusion (NMP) helps increase the use of extended criteria donor livers. However, the impact of an NMP program on waitlist times and mortality has not been evaluated. Adult patients listed for liver transplant (LT) at 2 academic centers from January 1, 2015, to September 1, 2023, were included (n=2773) to allow all patients ≥6 months follow-up from listing.

Expanding Selection Criteria in Deceased Donor Liver Transplantation for Hepatocellular Carcinoma: Long-term Follow-up of a National Registry and 2 Transplant Centers.

Background: This study compares selection criteria for liver transplant (LT) for hepatocellular carcinoma (HCC) for inclusivity and predictive ability to identify the most permissive criteria that maintain patient outcomes.

Methods: The Scientific Registry of Transplant Recipients (SRTR) database was queried for deceased donor LT's for HCC (2003-2020) with 3-y follow-up; these data were compared with a 2-center experience. Milan, University of California, San Francisco (UCSF), 5-5-500, Up-to-seven (U7), HALT-HCC, and Metroticket 2.

Post liver transplant short term and survival outcomes in patients living with obesity.

The objectives of our study were to examine and compare patient and graft survival over a 5-year period across BMI groups, and examine immediate and short-term complications post-LT. This was a retrospective study that examined all liver transplants that occurred at our institution between January 2015-October 2022. Patients were divided into 4 BMI groups (n = 888): normal-overweight (BMI 18.

Emerging and Clinically Accepted Biomarkers for Hepatocellular Carcinoma.

Hepatocellular carcinoma (HCC) is the third leading cause of cancer-related death and the sixth most diagnosed malignancy worldwide. Serum alpha-fetoprotein (AFP) is the traditional, ubiquitous biomarker for HCC. However, there has been an increasing call for the use of multiple biomarkers to optimize care for these patients.

Circulating Tumor DNA Profiling in Liver Transplant for Hepatocellular Carcinoma, Cholangiocarcinoma, and Colorectal Liver Metastases: A Programmatic Proof of Concept.

Introduction: Circulating tumor DNA (ctDNA) is emerging as a promising, non-invasive diagnostic and surveillance biomarker in solid organ malignancy. However, its utility before and after liver transplant (LT) for patients with primary and secondary liver cancers is still underexplored.

Methods: Patients undergoing LT for hepatocellular carcinoma (HCC), cholangiocarcinoma (CCA), and colorectal liver metastases (CRLM) with ctDNA testing were included.

Risk assessment in liver transplantation for hepatocellular carcinoma: long-term follow-up of a two-centre experience.

Background: Liver transplantation (LT) is a well-established treatment for hepatocellular carcinoma (HCC), but there are ongoing debates regarding outcomes and selection. This study examines the experience of LT for HCC at a high-volume centre.

Methods: A prospectively maintained database was used to identify HCC patients undergoing LT from 2000 to 2020 with more than or equal to 3-years follow-up.

Immunotactoid hepatopathy: A novel entity with histologically proven recurrence post liver transplantation.

Immunotactoid deposition is a rare fibrillary deposition disease that is primarily seen in the kidney and is associated with paraproteinemia. Here, we report a case of hepatic immunotactoid deposition in a 67-year-old male with a history of smoldering myeloma and chronic kidney disease who underwent liver transplantation for metabolic dysfunction-related cirrhosis. Immunotactoid deposition was first identified in the explanted liver and recurred in the allograft within only 7 weeks following transplantation, presenting as ascites with normal liver function tests.

Thromboelastography characteristics in critically ill patients with liver disease.

Objective: The purpose of this study was to determine how thromboelastography (TEG) parameters differ by various clinical conditions that commonly occur in patients with cirrhosis, including sepsis, acute on chronic liver failure (ACLF), alcohol-associated hepatitis (AAH) and portal vein thrombosis (PVT).

Background: TEG, a whole blood assay, is used to assess several parameters of coagulation and is becoming increasingly used in clinical practice.

Study: This study was a retrospective chart review of 155 patients admitted to the ICU with decompensated cirrhosis from 2017 to 2019.

Combined Liver Transplant and Cardiac Surgery: Long-Term Outcomes and Predictors of Success.

Objective: We aim to report our institutional outcomes of single-staged combined liver transplantation (LT) and cardiac surgery (CS).

Summary Background Data: Concurrent LT and CS is a potential treatment for combined cardiac dysfunction and end-stage liver disease, yet only 54 cases have been previously reported in the literature. Thus, the outcomes of this approach are relatively unknown, and this approach has been previously regarded as extremely risky.

Screening Modalities for Coronary Artery Disease in Liver Transplant Candidates: A Review of the Literature.

Patients with cirrhosis undergoing liver transplant (LT) are at high risk of postoperative cardiopulmonary complications. It is known that patients with coronary artery disease (CAD) have greater rates of post-LT morbidity and mortality than patients without CAD. Thus, identifying significant CAD in LT candidates is of the utmost importance to optimize survival posttransplant.

Neoplastic Progression of Barrett's Esophagus Among Organ Transplant Recipients: a Retrospective Cohort Study.

Background: Several small studies reported high risk of progression to high-grade dysplasia (HGD) and esophageal adenocarcinoma (EAC) in Barrett's esophagus (BE) patients who undergo solid organ transplantation (SOT) and implied that this may be due to immunosuppressant use. However, the major shortcoming of these studies was the lack of a control population. Therefore, we aimed to determine the rates of neoplastic progression in BE patients who underwent SOT and compare to that in controls and identify the predictors of progression.

Liver Paired Exchange: Programmatic Hopes and Fears.

The dearth of deceased liver donors has created a supply demand gap, necessitating creation of living donor liver transplantation. However, living donor liver transplantation has relied on directed donation, whereby many potential directed donors are rejected based on ABO blood group incompatibility, hepatic size incompatibility, or the need for biliary or arterial reconstruction during transplant surgery. Much like kidney paired exchange, liver paired exchange (LPE) circumvents these incompatibility issues by relying on anonymous, nondirected, or bridge donors that are better anatomical or histological matches for recipients.

Positive autoantibodies in living liver donors.

Background: There is a nationwide shortage of organs available for liver transplantation. Living donors help meet this growing demand. Not uncommonly, donors will have positive autoantibodies.

Therapies for non-alcoholic fatty liver disease: A 2022 update.

The incidence of non-alcoholic fatty liver disease (NAFLD) is rapidly increasing and lifestyle interventions to treat this disease by addressing the underlying metabolic syndrome are often limited. Many pharmacological interventions are being studied to slow or even reverse NAFLD progression. This review for hepatologists aims to provide an updated understanding of the pathogenesis of NAFLD, current recommended therapies, and the most promising treatment options that are currently under development.

Epstein-Barr virus-associated smooth muscle tumors in immunocompromised patients: Six case reports.

Background: Epstein-Barr virus associated smooth muscle tumor (EBV-SMT) is a rare oncological entity. However, there is an increasing incidence of EBV-SMTs, as the frequency of organ transplantation and immunosuppression grows. EBV-SMT diagnosis relies on histopathology and immunochemical staining to distinguish it from post-transplant lymphoproliferative disorder (PTLD).

Hepatic Epstein-Barr Virus-Associated Smooth Muscle Tumor in a Heart and Liver Transplant Recipient.

Epstein-Barr virus (EBV)-associated smooth muscle tumors (SMT) have been described in immunosuppressed states, including in post-transplant patients. Here, we discuss a heart-liver transplant recipient who was found to have multifocal hepatic EBV-SMT. His immunosuppression was initially transitioned from tacrolimus to sirolimus because of the proposed benefits of the mechanistic target of rapamycin inhibitors on EBV-SMT.

Cardiac considerations in liver transplantation.

Cardiovascular events have a major impact on overall outcomes after liver transplantation. Today's transplant patients are older than those in the past and therefore are more likely to have coexisting cardiac comorbidities. In addition, pathophysiologic effects of advanced liver disease on the circulatory system pose challenges in perioperative management.

Factors predicting futility of liver transplant in elderly recipients: A single-center experience.

Background: As the population of the United States ages, there has been an increasing number of elderly patients with cirrhosis listed for transplant. Previous studies have shown variable results in terms of the relative survival benefit for elderly liver transplant (LT) recipients. There may be factors that are associated with a poor post-transplant outcome which may help determine which elderly patients should and should not be listed for LT.

Safety of anti-TNF agents in patients with compensated cirrhosis: a case-control study.

Background: There is limited data on the use of anti-TNF agents in patients with concomitant cirrhosis. The aim of this study is to assess the safety of anti-TNF agents in patients with compensated cirrhosis who used these medications for the treatment of an underlying rheumatologic condition or IBD.

Methods: Multicenter, retrospective, matched, case-control study.

A guide to diagnosing and managing ascites in cirrhosis.

Combined serum and ascites fluid measurements point to the cause of ascites. For patients with modest edema, a reduced weight-loss target with diuresis may be acceptable.
