Abstract
Organ transplantation saves and transforms lives. Failure to secure consent for organ retrieval is widely regarded as the single most important obstacle to transplantation. A soft opt‐out system of consent for deceased organ donation was introduced into Wales in December 2015, whilst England maintained the existing opt‐in system. Cumulative data on consent rates in Wales were compared with those in England, using a two‐sided sequential procedure that was powered to detect an absolute difference in consent rates between England and Wales of 10%. Supplementary risk‐adjusted logistic regression analysis examined whether any difference in consent rates between the two nations could be attributed to variations in factors known to influence UK consent rates. Between 1 January 2016 and 31 December 2018, 8192 families of eligible donors in England and 474 in Wales were approached regarding organ donation, with overall consent rates of 65% and 68%, respectively. There was a steady upward trend in the proportion of families consenting to donation after brain death in Wales as compared with England and after 33 months, this reached statistical significance. No evidence of any change in the donation after circulatory death consent rate was observed. Risk‐adjusted logistic regression analysis revealed that by the end of the study period the probability of consent to organ donation in Wales was higher than in England (OR [95%CI] 2.1 [1.26–3.41]). The introduction of a soft opt‐out system of consent in Wales significantly increased organ donation consent though the impact was not immediate.

Abstract
Of 45 patients with chronic active hepatitis, 17 had taken paracetamol before the onset of symptoms. There were no significant differences, however, between the two groups in abnormalities of liver function tests, nor in ease of control after paracetamol withdrawal and institution of immunosuppressive therapy. The patient who had taken more than 5 g/week was studied in greater detail, but after a challenge dose of 1 g paracetamol there was no rise in serum aminotransferases and the pattern of excretion of paracetamol metabolites was normal. A critical review of the previously published reports failed to uncover any convincing evidence that paracetamol is an initiating factor in the development of chronic active hepatitis, although it may, at therapeutic levels, cause a toxic hepatitis in those individuals at risk.

Abstract
Transplant-mediated alloimmune thrombocytopenia (TMAT) from donors with immune thrombocytopenia (ITP) can result in significant bleeding complications in the recipient. The risk to a recipient of TMAT if they receive an organ from a donor with ITP is unknown. The outcomes of recipients of organs from deceased donors with ITP recorded in the UK Transplant Registry between 2000 and 2015 were reviewed. Twenty-one deceased organ donors had a predonation diagnosis of ITP. These donors were significantly more likely to have died from intracranial hemorrhage than were all other deceased organ donors (85% vs. 57%, p < 0.001). Organs from donors with ITP resulted in 49 organ transplants (31 kidney, 14 liver, four heart), with only one case of TMAT, which occurred in a liver transplant recipient and resulted in death from bleeding complications 18 days posttransplantation. The recipient of a kidney from the same organ donor was not affected. Unadjusted 5-year patient and graft survival was significantly worse for liver transplant recipients from donors with ITP compared with liver transplant recipients from donors without ITP (64% vs. 85%, p = 0.012). Organs from donors with ITP may be considered for transplantation, but livers should be used with caution.

Abstract
At a national policy level, the United Kingdom is at the forefront of recognizing the role of faith and its impact on organ donation. This is demonstrated by the recommendations of the Organ Donation Taskforce, National Institute for Clinical Excellence guidelines on organ donation, All-Party Parliamentary Kidney Group, and National Black, Asian and Minority Ethnic Taskforce Alliance. Evidence to date shows that further thought is required to ensure the active engagement of faith communities with organ donation in the UK. The "Taking Organ Transplantation to 2020" strategy was launched in July 2013 by National Health Service Blood and Transplant (NHSBT) in collaboration with the Department of Health and Welsh, Scottish, and Northern Irish governments and seeks to increase the number of people, from all sections of the UK's multiethnic and multifaith population, who consent to and authorize organ donation in their life. NHSBT seeks to work in partnership with faith leaders and this culminated in a Faith and Organ Donation Summit. Faith leaders highlight that there is a need for engagement at both national and local levels concerning organ donation as well as diagnosis and definition of death.

Abstract
BACKGROUND Age at presentation with primary biliary cholangitis (PBC) is associated with differential response to ursodeoxycholic acid (UDCA) therapy. Younger-presenting patients are less likely to respond to treatment and more likely to need transplant or die from the disease. PBC has a complex impact on quality of life (QoL), with systemic symptoms often having significant impact. AIM To explain the impact of age at presentation on perceived QoL and the inter-related symptoms which impact upon it. METHODS Using the UK-PBC cohort, symptoms were assessed using the PBC-40 and other validated tools. Data were available on 2055 patients. RESULTS Of the 1990 patients reporting a global PBC-QoL score, 66% reported good/neutral scores and 34% reported poor scores. Each 10-year increase in age at presentation was associated with a 14% decrease in risk of poor perceived QoL (OR = 0.86, 95% CI: 0.75-0.98, P < 0.05). All symptom domains were similarly age-associated (P < 0.01). Social dysfunction was the symptom factor with the greatest impact on QoL. Median (interquartile range) PBC-40 social scores for patients with good perceived QoL were 18 (14-23) compared with 34 (29-39) for those with poor QoL. CONCLUSION The majority of patients with primary biliary cholangitis do not feel their QoL is impaired, although impairment is reported by a sizeable minority. Age at presentation is associated with impact on perceived QoL and the symptoms impairing it, with younger patients being more affected. Social dysfunction makes the greatest contribution to QoL impairment, and it should be targeted in trials aimed at improving life quality.

Abstract
The Banff Working Group on Liver Allograft Pathology reviewed and discussed literature evidence regarding antibody-mediated liver allograft rejection at the 11th (Paris, France, June 5-10, 2011), 12th (Comandatuba, Brazil, August 19-23, 2013), and 13th (Vancouver, British Columbia, Canada, October 5-10, 2015) meetings of the Banff Conference on Allograft Pathology. Discussion continued online. The primary goal was to introduce guidelines and consensus criteria for the diagnosis of liver allograft antibody-mediated rejection and provide a comprehensive update of all Banff Schema recommendations. Included are new recommendations for complement component 4d tissue staining and interpretation, staging liver allograft fibrosis, and findings related to immunosuppression minimization. In an effort to create a single reference document, previous unchanged criteria are also included.

Abstract
BACKGROUND Transplanted organs carry the risk of inadvertent donor cancer transmission. Some cancers in organ donors have been classified as being associated with a high or unacceptable risk, but the evidence for such recommendations is scanty. METHODS The risk of cancer transmission from donors characterized as high or unacceptable risk was studied by analysing transplant and cancer registry data. Donors and recipients from England (1990-2008) were identified from the UK Transplant Registry. Cancer details were obtained from cancer registries and classified using guidelines from the Council of Europe and Organ Procurement and Transplantation Network/United Network for Organ Sharing. RESULTS Of 17,639 donors, 202 (1.1 per cent) had a history of cancer, including 61 donors with cancers classed as having an unacceptable/high risk of transmission. No cancer transmission was noted in 133 recipients of organs from these 61 donors. At 10 years after transplantation, the additional survival benefit gained by transplanting organs from donors with unacceptable/high-risk cancer was 944 (95 per cent confidence interval (c.i.) 851 to 1037) life-years, with a mean survival of 7.1 (95 per cent c.i. 6.4 to 7.8) years per recipient. CONCLUSION Strict implementation of present guidelines is likely to result in overestimation of cancer transmission risk in some donors. Organs from some donors with cancers defined as unacceptable/high risk can be used safely.

Abstract
OBJECTIVE To evaluate mildly abnormal liver function test (LFT) results in general practice among patients who do not have known liver disease. DESIGN Prospective cohort study of people with abnormal LFT results identified in primary care. Participants were intensively investigated using a common protocol and followed up for 2 years. Substudies investigated the psychological sequelae of abnormal test results, clinicians' reasons for testing, decision options when LFT results were abnormal and early detection of liver fibrosis. SETTING Eleven primary-care practices: eight in Birmingham and three in Lambeth. PARTICIPANTS Adults with abnormal LFT results who did not have pre-existing or obvious liver disease. Eight analytes were included in the panel of LFTs. MAIN OUTCOME MEASURES Statistical tests were used to identify the interactions between clinical features, the initial pattern of abnormal LFT results and (1) specific viral, genetic and autoimmune diseases, such as viral hepatitis, haemochromatosis and primary biliary cirrhosis; (2) a range of other serious diseases, such as metastatic cancer and hypothyroidism; (3) 'fatty liver' not associated with the above; and (4) the absence of detectable disease. RESULTS Fewer than 5% of people with abnormal LFT results had a specific disease of the liver, and many of these were unlikely to need treatment. The diagnostic potential of the LFT panel is largely subsumed into just two analytes: alanine aminotransferase (ALT) and alkaline phosphatase (ALP). Gamma-glutamyltransferase (GGT) offers a small increase in sensitivity at the margin at the cost of a large loss of specificity. Eighty-four per cent of abnormal LFT results remain abnormal on retesting 1 month later. In many cases, carrying out a definitive or specific test will be more efficient than repeating LFTs, with a view to specific testing only if the test remains abnormal. An ultrasound diagnosis of 'fatty liver' was present in nearly 40% of patients with abnormal LFTs and a small amount of weight loss over 2 years was associated with a reduced incidence of liver fat. There was a J-shaped relationship between alcohol intake and fatty liver in men. An abnormal LFT result causes temporary anxiety, which does not appear to promote sustained behaviour change. CONCLUSIONS Liver disease is rare among people with abnormal LFT results in primary care. Only two analytes (ALT and ALP) are helpful in identifying the majority of liver disease. GGT adds little information in return for a high false-positive rate but it is sensitive to alcohol intake. LFT results seldom revert from abnormal to normal over a 1-month period, and modelling shows that repeating an abnormal LFT panel, as recommended in the current guidelines, is inefficient. LFTs are often undertaken to meet perceived patient need for a blood test, but as they are neither specific nor indicative of any particular disease they are among the least suitable tests for this purpose. Obesity and raised ALT provide strong evidence for a presumptive diagnosis of 'fatty' liver. Abnormal LFTs and 'fatty' liver provoke only short-term anxiety and neither is associated with sustained weight loss. Even a small amount of weight loss reduces liver fat. FUTURE WORK RECOMMENDATIONS (1) the cases of 'fatty liver' and controls should be followed up in the long term to identify features that predict development of hepatosteatosis and then cirrhosis; (2) the acceptability of replacing the traditional six- to eight-analyte LFT panel with a drop down menu including the ALT/ALP combination should be evaluated.

Abstract
An increased incidence of malignancy is an established complication of organ transplantation and the associated immunosuppression. In this study on cancer incidence in solid organ transplant recipients in Britain, we describe the incidence of de novo cancers in the allograft recipient, and compare these incidences following the transplantation of different organs. Data in the UK Transplant Registry held by NHS Blood and Transplant (NHSBT) were linked with data made available by the cancer registries in England, Scotland and Wales. Incidence rates in the transplanted population were then compared with the general population, using standardized incidence ratios matched for age, gender and time period. The 10-year incidence of de novo cancer in transplant recipients is twice that of the general population, with the incidence of nonmelanoma skin cancer being 13 times greater. Nonmelanoma skin cancer, cancer of the lip, posttransplant lymphoproliferative disease and anal cancer have the largest standardized incidence ratios, but the incidence of different types of malignancy differs according to the organ transplanted. Patterns in standardized incidence ratios over time since transplantation are different for different types of transplant recipient, as well as for different malignancies. These results have implications for a national screening program.

Abstract
Alcohol-related liver disease (ALD) is one of the most common indications for liver transplantation (LT). Long-term outcome after LT for ALD versus other etiologies is still under debate. The aim of this study was to compare outcome after LT of patients with ALD, viral (VIR), and cryptogenic cirrhosis. Donor, graft and recipient ELTR variables were analysed in transplants for alcoholic and nonalcoholic cirrhosis (1988-2005) and were correlated with patient survival. Causes of death and/or graft failure were compared between groups. Nine thousand eight hundred eighty ALD, 10,943 VIR, 1478 ALD+VIR and 2410 cryptogenic (CRYP) liver transplants were evaluated. One, 3, 5 and 10 years graft survival rates after LT in ALD patients were 84%, 78%, 73%, 58%, significantly higher than in VIR and CRYP (p=0.04, p=0.05). By multivariate analysis, ALD+VIR (RR 1.14) and viral alone (RR 1.06) were significant risk factors for mortality. De novo tumors, cardiovascular and social causes were causes of death/graft failure in higher percentage in ALD groups versus other etiologies. LT for ALD cirrhosis has a favorable outcome, however, hepatitis C virus co-infection seems to eliminate this advantage. Screening for de novo tumors and prevention of cardiovascular complications are essential to provide better long-term results.

Abstract
Approximately 90% of liver transplant patients are alive after 1 year and 75% after 5 years with the majority leading full and near-normal lives. However, although early mortality rates after transplantation have fallen dramatically over the last 2 decades, the rates of late graft loss and patient death have remained constant. Thus, understanding of the causes of graft and patient failure is essential to improve long-term outcomes. In the early days after liver transplantation, ischemia and reperfusion injuries predominate, with acute cellular rejection relatively common in first 3 months. Thereafter, the causes of graft dysfunction are variable with disease recurrence as a major cause of graft loss. In this review, we discuss causes of graft dysfunction after 6 months.

Abstract
BACKGROUND The increasing shortfall between the number of patients who would benefit from liver transplantation and the availability of donor livers means that rationing has to occur. The processes of selection of patients for transplantation and for allocation of donor livers should be done according to ethical and, where possible, evidence-based criteria so that there is clarity and that the competing requirements of equity, justice, utility and benefit can be balanced. METHODS To achieve these goals for patients in the United Kingdom in need of transplantation, we have developed guidelines for the selection of patients to the national waiting list based on the risk of death without a transplant and the ability of the procedure to improve the recipient's quality of life. Guidelines have been developed for both those with acute liver failure and chronic liver disease. Allocation will depend on matching of the donor liver to the recipient. RESULTS The proposed system, to be introduced into the UK compares with some other systems, where different models for selection and allocation have been introduced.

Abstract
BACKGROUND Liver transplantation is a very successful therapy for those with end stage disease. Although there are numerous data on patient and graft survival after liver transplantation, life expectancy and possible loss of life (compared with a normal matched population) in those who survive remains unknown. AIMS To assess the life expectancy and life years lost of adult liver allograft recipients, compared with an age and sex matched UK population to provide patients with more information and to improve the use of a scarce resource. METHODS Using the National Transplant Database held by UK Transplant, on over 3600 adult liver allograft recipients transplanted between 1985 and 2003, we analysed survival of all adults who survived more than six months after transplantation and compared survival after transplantation with national age and sex matched controls to assess life years lost. RESULTS Estimated median survival time of the analysis cohort of 2702 adult liver allograft recipients was 22.2 years (95% confidence interval 19.3-25.6), with an estimated loss of seven life years compared with an age and sex matched population. CONCLUSIONS Overall, female recipients have a longer life expectancy and lose fewer life years than male recipients. While younger recipients have a longer life expectancy, they also lose more life years. Those transplanted for cancer, hepatitis C virus infection, and alcoholic liver disease had the greatest loss of life years.

Abstract
The choice of immunosuppressive regime used after liver transplantation depends on many factors, which should include the effect of disease recurrence; recurrence of disease after liver transplantation may be affected by the degree and type of immunosuppression used and recurrent disease may affect patient and graft survival. For autoimmune diseases, recurrence of primary biliary cirrhosis develops sooner and more rapidly in those on tacrolimus compared with cyclosporine, but graft loss from recurrent disease is uncommon; recurrence rates of primary sclerosing cholangitis is unaffected by immunosuppressive regimes and recurrence of autoimmune hepatitis may be reduced by prescription of corticosteroids. Whether the immunosuppressive regime affects the pattern of hepatocellular carcinoma recurrence is uncertain. It is probable that the use of calcineurin inhibitor does not have a significant effect and inhibitors of TOR may have an anti-cancer effect, but this still has to be shown clinically. Most metabolic diseases are not affected by the choice of immunosuppression, although recurrence of sarcoidosis may be prevented by corticosteroids.

Abstract
Over the last two decades there has been a significant increase in the number and types of immunosuppressive agents that have been available to clinicians. The protocols for immunosuppression used in liver transplantation have been derived historically from those in renal transplantation. During the last decade there has been a shift in the use of immunosuppression, with the introduction of interleukin (IL)-2 receptor antagonists in place of anti-lymphocyte preparations, substitution of tacrolimus for cyclosporin and mycophenolate for azathioprine. The use of corticosteroids has been reduced. For a variety of reasons, these changes have not always been made on the basis of properly randomized studies. The place of newer agents, such as sirolimus and leflunomide derivatives and of the microbiological agents, is unclear. In this review, we outline briefly the mechanism of action of drugs and suggest possible approaches to the management of the liver allograft recipient, suggesting how treatment could be adjusted according to the indication for transplantation as well as the individual's comorbidities.

Abstract
The shortage in cadaveric donor livers is pushing the transplant centers to expand the pool by using "marginal" donors. Primary biliary cirrhosis (PBC) remains an important indication for transplantation. We conducted a retrospective analysis of prospectively collected data in a well-defined group of patients with PBC where 301 consecutive donor-PBC recipient pairs transplanted were analyzed to identify donor and operative factors influencing recipient outcome. Mean follow-up was 56 months. The 1-, 3- and 5-year actuarial patient and graft survival was 93.97%, 90.64%, and 81.75%, and 85.49%, 82.57%, and 75.21%, respectively. Factors showing influence in decreased total patient survival were recipient old age (P = 0.003) and low recipient albumin (P = 0.01). However, the only variables showing an association with decreased patient survival within 90 days are old donor age (P = 0.002) and high donor body weight (P = 0.03) or high body mass index (BMI) (P = 0.055). Cold ischaemic time (CIT) of 18 hours showed statistical significance in patient survival (P = 0.025). Obesity did have a significant adverse impact on survival compared with normal or overweight donors (BMI < 30), decreasing survival by 50% at 5 years. In conclusion, this study of several factors considered "marginal" for transplantation in a recipient population with predictable liver disease (PBC), donor BMI and age were shown to be associated with decreased graft and patient survival.

Abstract
Increased opioidergic neurotransmission in the brain appears to contribute to the pruritus that complicates cholestasis and certain non-cholestatic chronic liver diseases. Opiate antagonists have been shown to decrease scratching activity in patients with the pruritus of cholestasis. Initiation of oral administration of an orally bioavailable opiate antagonist may precipitate a florid opioid-withdrawal-like reaction in patients with pruritus complicating cholestasis. Such reactions can be minimized, or avoided completely, by cautiously infusing naloxone before giving small oral doses of an orally bioavailable opiate antagonist. The infusion rate of naloxone should initially be very low; it should be increased gradually and stopped when a rate known to be associated with opioid antagonist effects has been attained. Oral therapy with an opiate antagonist can then be initiated.

Abstract
A woman with stage III (pre-cirrhotic) primary biliary cirrhosis was referred for liver transplantation because of intractable pruritus. Oral administration of 50 mg naltrexone precipitated a severe opioid withdrawal-like reaction. Subsequently, when oral naltrexone therapy was reintroduced following a cautious infusion of naloxone, no reaction occurred and the pruritus resolved completely. Liver transplantation should not be considered for apparently intractable pruritus of cholestasis before an adequate trial of opiate antagonist therapy.

Abstract
The immunodominant antimitochondrial antibody (AMA) response in primary biliary cirrhosis (PBC) is directed against the E2 component of pyruvate dehydrogenase (PDC-E2). The nature of the clonal selection process is unclear, and to address this issue, we took advantage of a transgenic technology, XenoMouse, that contains 80% of the human immunoglobulin (Ig) variable gene repertoire and can produce high-affinity human antibodies to virtually any immunogen without evidence of clonal bias. We immunized mice with PDC-E2 to obtain 13 HmAbs, including 4 IgG(2) and 9 IgM isotypes. Immunoglobulin gene analysis was unique and demonstrated a clonal bias; the immunoglobulin gene usage was considerably different from other antibody responses analyzed in XenoMouse systems. Four of the 13 mAbs recognized the inner lipoyl domain of PDC-E2, 2 of 13 recognized the entire PDC-E2 molecule, 4 of 13 recognized PDC-E2 and OGDC-E2, 1 of 13 recognized OGDC only, 1 recognized BCOADC-E2 only, and 1 recognized an unidentified 100-kd mitochondrial protein. Immunohistochemical staining using these HmAbs produced mitochondrial staining of septal bile ducts in both PBC and control livers. Ig gene analysis showed that 7 of 13 HmAbs used the V(H)3 and 4 of 13 used VH4 gene repertoire, respectively. Three of 7 V(H)3 antibodies used the same Ig VH3-21 gene family found in human AMA from patients with PBC. The CDRs of these autoantibodies were slightly mutated when compared with the sequences present within the Ig germline genes. In conclusion, the XenoMouse not only recapitulates the unique specificity and restriction of PBC patients, but indicates that the autoantibodies are derived from a restricted clonal selection process. Such data suggest that the original immunogen leads to somatic mutation without subsequent development of determinant spreading.

Abstract
Both the number of recipients awaiting liver transplantation and the length of wait are increasing, giving rise to increasing concern by patients, healthcare professionals, and the public. Greater attention has been focused on the criteria for listing patients for transplantation and for allocation of organs. In the U.K., compared with the U.S., the delivery of liver transplant services is more tightly regulated, with fewer transplant centers, lower transplant rates, shorter waiting lists, and shorter waiting times. The reasons for these differences are unclear. In the U.K., patients are listed only if there is a reasonable expectation that the patient will receive a graft. The criteria for listing are based on overall utility rather than individual benefit, so the criterion for listing is that the patient will have at least a greater than 50% probability of being alive 5 years after transplantation with a quality of life that is acceptable to the patient. Although it is reasonable to offer hope to all patients, this hope should have a reasonable probability of being fulfilled. Listing patients with little likelihood of benefiting from transplantation is not helpful either for the patient, their family, or the other potential liver allograft recipients. While different systems for allocation of donor livers may be more appropriate in other settings, the process in the U.K. seems to deliver satisfactorily.

Abstract
BACKGROUND Although some centers have reported very good patient and graft survival in liver allograft recipients, reports from both North America (United Network of Organ Sharing) and Europe (European Liver Transplantation Registry) have failed to confirm this. AIM We have reviewed our experience of liver transplantation in older recipients and compared their clinical outcome to a younger group. METHODS Retrospective analyses were conducted on 875 consecutive adult patients undergoing liver transplantation for chronic liver disease, between 1990 and 1999. Group I consisted of patients under 60 years of age (n=701; 80.2%) and group II of patients over 60 years (n=174; 19.8%). RESULTS The proportion of older patients transplanted increased from 10.15% between 1990-1991 to 20.85% (1997-1999). Actuarial graft survival at 1, 3, and 5 years was 78%, 74%, and 69% and 78%, 73%, and 66% for groups I and II, respectively (P=0.49). The overall actuarial patient survival tended to be better in the younger group (1-, 3-, and 5-year survival of 83%, 79%, and 76% for group I and 81%, 75%, and 69% for group II (P=0.07). Crude mortality probability shows a stable trend until 45 years, a gradual increase in mortality between 45 and 60 years, and then the risk of death is accelerated. The same analysis shows the risk of death is between 1.5 and 2 times greater in Child C patients; this is greater in patients aged more than 66 years. CONCLUSION There is no statistically significant difference in patient or graft survival in patients aged over 60 compared to younger recipients. However, when age is assessed as a continuous variable, an adverse effect of older age is seen on outcome and this effect is more marked in sicker patients.

Abstract
BACKGROUND/AIMS The understanding of the physiology and function of human biliary epithelial cells (hBEC) has been improved by studies in monolayer culture systems. The aim was to develop a polarized model to elucidate the mechanisms of ductular morphogenesis and functional differentiation of hBEC. METHODS The morphological, phenotypic and functional properties of hBEC cultured as three-dimensional aggregates in collagen gel were assessed in medium supplemented with (or without) human hepatocyte growth factor (hHGF) and foetal bovine serum. RESULTS In the absence of added mitogens and serum, cells maintained as morphologically polarized aggregates, organized around a central lumen, were positive for phenotypic markers of biliary epithelium and negative for markers of other cell types. Functional markers, gamma-glutamyl-transferase, anion exchanger-2, responses to gamma interferon and forskolin induced secretion, were preserved. hHGF increased both the size and number of aggregates and induced hBEC to invade the gel and lumena forming anastomosing networks of cells. CONCLUSIONS Collagen gel culture in the absence of added growth factors and serum provides a model for analysis of the polarized functions of hBEC. The formation of poorly organized cords of cells in response to hHGF suggests that collagen gel culture may provide a model for the investigation of atypical ductular morphogenesis of the human biliary tract.

Abstract
The aim of this study performed at the Liver Unit at the Queen Elizabeth Hospital, Birmingham, UK, is to assess posttransplantation alcohol consumption and identify risk factors associated with recidivism. This retrospective case-control study used a self-report questionnaire to assess pretransplantation and posttransplantation drinking, and a retrospective cohort study used patient notes to analyze risk factors for recidivism. Of 64 patients who underwent transplantation for alcoholic liver disease (ALD) between May 1996 and November 1999, a total of 49 surviving patients (40 men, 9 women) were available for study. The comparison group consisted of 49 patients matched for age, sex, and date of transplantation who underwent transplantation for non-alcohol-induced chronic liver disease. Two-year patient survival rates were 82% in both study groups. The questionnaire response rate was 69.3% and 75.5% in patients with and without ALD, respectively. Data on recidivism (defined as any alcohol consumption after transplantation) were available in 46 of the 49 patients with ALD. Of these, 45.6% were drinking; 21.7% reported only occasionally drinking; 17.3%, moderate drinking; and 6.5%, heavy drinking. Information on alcohol consumption was available from 41 of the 49 controls. Of these, 52.5% consumed alcohol; 22.0% reported drinking only on special occasions; 24.4%, moderate drinking; and 4.9%, a return to heavy drinking. However, these differences were not statistically significant, and log-rank analysis found no significant difference in time to resumption of drinking. In the ALD cohort, no significant risk factors were identified to predict recidivism. No pretransplantation risk factors (including period of abstinence before transplantation) correlated with recidivism. Survival after transplantation for ALD is similar to that in other forms of chronic liver disease. Recidivism rates for patients with ALD are high, but patients with ALD do not drink more than their control counterparts posttransplantation. In most instances, alcohol consumption posttransplantation is minimal to moderate (<20 units/wk) and seems to be controlled.

Abstract
Orthotopic liver transplantation (OLT) is an effective treatment for patients with advanced primary biliary cirrhosis (PBC). We have conducted a retrospective analysis of 400 consecutive patients transplanted for PBC between 1983 and 1999. Mean follow-up was 56 months. The proportion of patients grafted for PBC fell progressively, from 35% in 1990 (n = 80) to 21% in 1999 (n = 111); comparison of patients grafted in the 2 decades showed that the median age increased from 53 to 56 years and the median serum bilirubin at transplantation fell from 270 micromol/L to 132 micromol/L. The overall actuarial patient and graft survival at 1, 5, and 10 years is 83%, 78%, and 67% and 82%, 75%, and 61%, respectively. The net gain in 5-year survival compared with predicted survival in the absence of transplantation fell from 37% (range, 82%-90%) to 16% (range, 91%-99%). Multiple organ failure (16.1%) and sepsis (9.6%) were the major causes of early deaths (<6 months). Recurrent PBC, diagnosed on allograft histology, was found in 68 (17%) patients, at a mean time of 36 months. We were unable to identify any pretransplantation donor or recipient factor, which identified those patients at risk of recurrence, although recurrence was much earlier and more frequently seen in patients receiving tacrolimus (P =.04). PBC remains a good indication for liver transplantation, with excellent survival rates. The age at transplantation increased although patients tended to be grafted earlier. Survival rates have increased although there is a reduction in the survival benefit. Recurrence may be common, but does not seem to affect medium-term graft survival.

Abstract
The success of liver transplantation has resulted in its widespread use for end-stage liver disease; 1- and 5-year survival rates of 70-90% and 60-80% respectively have been reported. Indications for assessment for liver transplantation are now evidence-based and early referral is recommended, correlating with improved patient survival. The management of patients on the waiting list for liver transplantation is designed to prevent complications of liver disease and to avoid therapeutic misadventures. Following transplantation, rejection and infection dominate post-operative complications, and improvements in their prevention and treatment have also correlated with improved patient survival. The development and introduction into clinical practice of a variety of immunosuppressive agents has offered a bewildering array of therapeutic options but with a lack of evidence on which to select optimal immunosuppression. Similarly, difficulties remain in the treatment of some of the complications arising from liver transplantation such as recurrence of disease and complications of immunosuppression.

Abstract
Over the last decade there have been major advances in all aspects of liver transplantation with the consequence that the number of patients who could benefit from the procedure is increasing. As a result, the number of patients listed for liver transplantation is growing while the donor pool is remaining constant or even falling. The effect of this donor shortage is seen clearly both in Europe and in North America. For example, in North America data from UNOS shows that between 1988 and 1997 the number of cadaveric donor liver transplants rose from 1,713 to 4,100. The number of patients waiting for transplant rose over the same time from 616 to 9,647. This shortage of organs has tragic consequences. Although the proportion of patients dying on the waiting list is falling, the number of patients dying on the liver transplant waiting list increased from 196 to 1,129 over this same period of time.
