Organ Transplants From Deceased Donors With Primary Brain Tumors and Risk of Cancer Transmission.

Importance: Cancer transmission is a known risk for recipients of organ transplants. Many people wait a long time for a suitable transplant; some never receive one. Although patients with brain tumors may donate their organs, opinions vary on the risks involved.

Pretreatment prediction of response to ursodeoxycholic acid in primary biliary cholangitis: development and validation of the UDCA Response Score.

Background: Treatment guidelines recommend a stepwise approach to primary biliary cholangitis: all patients begin treatment with ursodeoxycholic acid (UDCA) monotherapy and those with an inadequate biochemical response after 12 months are subsequently considered for second-line therapies. However, as a result, patients at the highest risk can wait the longest for effective treatment. We determined whether UDCA response can be accurately predicted using pretreatment clinical parameters.

Proximity to transplant center and outcome among liver transplant patients.

In the United States, distance from liver transplant center correlates with worsened outcomes; the effects of geography elsewhere are unassessed. We performed a national registry analysis of United Kingdom listings for liver transplantation (1995-2014) and assessed whether travel time to transplant center correlates with outcome. There were 11 188 listings assessed (8490 transplanted), with a median travel time to center of 60 minutes (range 36-86).

Alcohol, Diet and Drug Use Preceding Alcoholic Hepatitis.

Background: Alcoholic hepatitis (AH) is a severe manifestation of alcohol-related liver disease characterised by jaundice and liver failure. It is not known what might trigger an episode of AH. We interviewed patients to investigate changes in behaviour before the onset of AH.

Twenty-Year Comparative Analysis of Patients With Autoimmune Liver Diseases on Transplant Waitlists.

Background & Aims: The rarity of autoimmune liver disease poses challenges to epidemiology studies. However, waitlists for liver transplantation can be used to study patients with end-stage liver diseases. We used these waitlists to assess trends in numbers and demographics of patients awaiting liver transplant for primary biliary cholangitis (PBC), primary sclerosing cholangitis (PSC), or autoimmune hepatitis (AIH).

Practical Recommendations for Long-term Management of Modifiable Risks in Kidney and Liver Transplant Recipients: A Guidance Report and Clinical Checklist by the Consensus on Managing Modifiable Risk in Transplantation (COMMIT) Group.

Short-term patient and graft outcomes continue to improve after kidney and liver transplantation, with 1-year survival rates over 80%; however, improving longer-term outcomes remains a challenge. Improving the function of grafts and health of recipients would not only enhance quality and length of life, but would also reduce the need for retransplantation, and thus increase the number of organs available for transplant. The clinical transplant community needs to identify and manage those patient modifiable factors, to decrease the risk of graft failure, and improve longer-term outcomes.

International comparison of liver transplant programmes: differences in indications, donor and recipient selection and outcome between Italy and UK.

Background & Aims: Comparing liver transplant (LT) programmes internationally can improve outcomes by stimulating cross-national learning. Yet, comparison of crude outcomes, by using registry data, is limited by missing data, not allowing proper risk-adjustment for donor- and recipient-related factors. The objective of this study was to compare two European LT programmes based on high-quality national longitudinal databases prospectively collected in Italy and UK respectively.

Rapid dissemination of human T-lymphotropic virus type 1 during primary infection in transplant recipients.

Background: Human T-lymphotropic virus type 1 (HTLV-1) infects an estimated 10 million persons globally with transmission resulting in lifelong infection. Disease, linked to high proviral load, occurs in a minority. In established infection HTLV-1 replicates through infectious spread and clonal expansion of infected lymphocytes.

The UK-PBC risk scores: Derivation and validation of a scoring system for long-term prediction of end-stage liver disease in primary biliary cholangitis.

Unlabelled: The biochemical response to ursodeoxycholic acid (UDCA)--so-called "treatment response"--strongly predicts long-term outcome in primary biliary cholangitis (PBC). Several long-term prognostic models based solely on the treatment response have been developed that are widely used to risk stratify PBC patients and guide their management. However, they do not take other prognostic variables into account, such as the stage of the liver disease.

Kidney donation after circulatory death (DCD): state of the art.

The use of kidneys from controlled donation after circulatory death (DCD) donors has the potential to markedly increase kidney transplants performed. However, this potential is not being realized because of concerns that DCD kidneys are inferior to those from donation after brain-death (DBD) donors. The United Kingdom has developed a large and successful controlled DCD kidney transplant program that has allowed for a substantial increase in kidney transplant numbers.

Improved access to histopathology using a digital system could increase the organ donor pool and improve allocation.

Improvements in digital slide scanners have reached a stage that digital whole slide images (WSIs) can be used for diagnostic purposes. A digital system for histopathology, analogous to the systems used in radiology, would allow the establishment of networks of subspecialist histopathologists to provide a regional, national or even international rota to support out of hours histopathology for emergency frozen sections, urgent paraffin sections and to generally improve efficiencies with the provision of histopathology services. Such a system would promote appropriate organ utilization by allowing rapid characterization of unexpected lesions in the donor to determine whether donation should occur and further characterization of the organ, such as the degree of fibrosis in the kidney or steatosis in the liver, to determine whether the organ should be used.

Autoimmune liver disease, autoimmunity and liver transplantation.

Primary biliary cirrhosis (PBC), primary sclerosing cholangitis (PSC) and autoimmune hepatitis (AIH) represent the three major autoimmune liver diseases (AILD). PBC, PSC, and AIH are all complex disorders in that they result from the effects of multiple genes in combination with as yet unidentified environmental factors. Recent genome-wide association studies have identified numerous risk loci for PBC and PSC that host genes involved in innate or acquired immune responses.

Alcohol and substance abuse in solid-organ transplant recipients.

This review focuses on alcohol and substance abuse in the context of solid-organ transplantation. Alcohol and substance abuse are common and may lead to a need for solid-organ transplantation and may also contribute to significant physical and psychologic problems that impact upon the recipient. Damaging levels of alcohol intake can occur in the absence of dependence.

Mental health disorders and solid-organ transplant recipients.

Depression affects up to 60% of solid-organ recipients and is independently associated with both mortality (hazard ratio for death of ~2) and de novo malignancy after transplantation, although the mechanism is not clear. Both pretransplantation psychosis and depression occurring more than 2 years after transplantation are associated with increased noncompliance and graft loss. It remains to be shown that effective treatment of depression is associated with improved outcomes and quality of life.

The effect of liver transplantation on fatigue in patients with primary biliary cirrhosis: a prospective study.

Background & Aims: The role of liver transplantation (LT) for the relief of fatigue in patients with primary biliary cirrhosis (PBC) is unclear, and while many centers exclude fatigue as an indication for transplantation, there have been no studies to prospectively evaluate the impact of LT on fatigue. We aimed at assessing the severity of fatigue in LT candidates with PBC and the impact of LT on fatigue.

Methods: In a prospective, longitudinal study, we used the PBC-40 questionnaire in 49 adult patients with PBC at listing and at 6, 12, and 24 months after LT and in two sex- and age-matched cohorts of community controls and non-transplanted PBC patients.

Impact of primary biliary cirrhosis on perceived quality of life: the UK-PBC national study.

Unlabelled: Primary biliary cirrhosis (PBC) has a complex clinical phenotype, with debate about the extent and specificity of frequently described systemic symptoms such as fatigue. The aim of this study was to use a national patient cohort of 2,353 patients recruited from all clinical centers in the UK to explore the impact of disease on perceived life quality. Clinical data regarding diagnosis, therapy, and biochemical status were collected and have been reported previously.

The impact of liver transplantation on the phenotype of primary biliary cirrhosis patients in the UK-PBC cohort.

Background & Aims: Liver transplantation improves survival in end-stage primary biliary cirrhosis (PBC), but the benefit for systemic symptoms including fatigue is less clear. The aim of this study was to utilise the comprehensive UK-PBC Research Cohort, including 380 post-transplant patients and 2300 non-transplanted patients, to answer key questions regarding transplantation for PBC.

Methods: Cross-sectional study of post-transplant PBC patients and case-matched non-transplanted patients.

Strategies for expanding the UK pool of potential intestinal transplant donors.

Background: The pool of suitable donors and listed recipients for intestinal transplantation is small, resulting in difficulties in donor-to-recipient matching and significant mortality on the waiting list. This study aims to help define the pool of potential donors for intestinal transplantation and propose methods for an increased utilization of donor bowels in the United Kingdom.

Methods: Data on bowel offering from 657 donors after brain stem death (DBD) and on 46 patients on the active intestinal transplant list over 12 months from 14 April 2011 were obtained from the UK Transplant Registry.

Sex and age are determinants of the clinical phenotype of primary biliary cirrhosis and response to ursodeoxycholic acid.

Unlabelled: BACKGROUND, & AIMS: Studies of primary biliary cirrhosis (PBC) phenotypes largely have been performed using small and selected populations. Study size has precluded investigation of important disease subgroups, such as men and young patients. We used a national patient cohort to obtain a better picture of PBC phenotypes.

HTLV-1 in solid-organ transplantation: current challenges and future management strategies.

Human T-cell lymphotrophic virus (HTLV)-1 has been reported after solid-organ transplantation, with a related fatal outcome in less than five cases. The natural history of HTLV-1 transmission from donor to recipient is unknown in this setting, because available screening platforms are suboptimal in low-prevalence areas and there is a lack of long-term follow-up. Minimizing organ wastage due to false-positive screening and avoiding donor-derived HTLV-associated diseases remain the goal.

Dense fine-mapping study identifies new susceptibility loci for primary biliary cirrhosis.

We genotyped 2,861 cases of primary biliary cirrhosis (PBC) from the UK PBC Consortium and 8,514 UK population controls across 196,524 variants within 186 known autoimmune risk loci. We identified 3 loci newly associated with PBC (at P<5×10(-8)), increasing the number of known susceptibility loci to 25. The most associated variant at 19p12 is a low-frequency nonsynonymous SNP in TYK2, further implicating JAK-STAT and cytokine signaling in disease pathogenesis.
