ABSTRACT

Primary sclerosing cholangitis (PSC) is the classical hepatobiliary manifestation of inflammatory bowel disease (IBD) and a lead indication for liver transplantation (LT) in the western world. In this article, we present a Consensus Statement on LT practice, developed by a dedicated Guidelines' Taskforce of the European Society of Organ Transplantation (ESOT). The overarching goal is to provide practical guidance on commonly debated topics, including indications and timing of LT, management of bile duct stenosis in patients on the transplant waiting list, technical aspects of transplantation, immunosuppressive strategies post-transplant, timing and extension of intestinal resection and futility criteria for re-transplantation.

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

Genotype 3 hepatitis E virus (HEV) can lead to persistent infections in immunocompromised hosts. A recently available commercial assay for the detection of HEV antigen (HEV-Ag ELISA, Wantai diagnostics) may enable the study of HEV-Ag dynamics in such persistent infections, however currently there is no confirmatory test available. We generated a putative neutralising reagent from a pool of four convalescent blood donor samples and explored neutralising activity against HEV antigens from clinical samples, HEV tissue-culture and virus-like particles. Using this neutralisation method we were able to differentiate true reactivity from non-specific reactivity in plasma, stool and urine samples. This could also facilitate the introduction of HEV-Ag detection as a screening assay or the study of HEV-Ag in different body fluids.

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

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

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: 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

BACKGROUND: The UK has implemented a national strategy for organ donation that includes a centrally coordinated network of specialist nurses in organ donation embedded in all intensive care units and a national organ retrieval service for deceased organ donors. We aimed to determine whether despite the national approach to donation there is significant regional variation in deceased donor kidney donation rates. METHODS: The UK prospective audit of deaths in critical care was analysed for a cohort of patients who died in critical care between April 2010 and December 2011. Multivariate logistic regression was used to identify the factors associated with kidney donation. The logistic regression model was then used to produce risk-adjusted funnel plots describing the regional variation in donation rates. RESULTS: Of the 27 482 patients who died in a critical care setting, 1528 (5.5%) became kidney donors. Factors found to influence donation rates significantly were: type of critical care [e.g. neurointensive vs general intensive care: OR 1.53, 95% confidence interval (CI) 1.34-1.75, P<0.0001], patient ethnicity (e.g. 'Asian' vs 'white': OR 0.17, 95% CI 0.11-0.26, P<0.0001), age (e.g. age >69 vs age 18-39 yr: OR 0.2, 0.15-0.25, P<0.0001), and cause of death [e.g. 'other' (excluding 'stroke' and 'trauma') vs 'trauma': OR 0.04, 95% CI 0.03-0.05, P<0.0001]. Despite correction for these variables, kidney donation rates for the 20 UK kidney donor regions showed marked variation. The overall standardized donation rate ranged from 3.2 to 7.5%. Four regions had donation rates of >2 standard deviations (sd) from the mean (two below and two above). Regional variation was most marked for donation after circulatory death (DCD) kidney donors with 9 of the 20 regions demonstrating donation rates of >2 sd from the mean (5 below and 4 above). CONCLUSIONS: The marked regional variation in kidney donation rates observed in this cohort after adjustment for factors strongly associated with donation rates suggests that there is considerable scope for further increasing kidney donation rates in the UK, particularly DCD.

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

We report a multicenter, prospective, randomized, open-label trial investigating the effect of lower levels and delayed introduction of tacrolimus on renal function in liver transplant recipients. Adult patients with good renal function undergoing primary liver transplant were randomized to either: group A (standard-dose tacrolimus [target trough levels >10 ng/mL] and corticosteroids; n = 183); group B (mycophenolate mofetil [MMF] 2g/day, reduced-dose tacrolimus [target trough levels

ABSTRACT

Metachromatic leukodystrophy (MLD) is a progressive white matter disease caused by arylsulfatase A deficiency. Demyelination in the nervous system is detected by cerebral magnetic resonance imaging (MRI) and neurophysiological studies. We present three children with infantile MLD, who had difficulties in standing and walking with absent reflexes. Protein levels in cerebral spinal fluid (CSF) were elevated and nerve conduction studies revealed slowing down of motor nerve conduction velocity. Initial cerebral MRIs showed no white matter changes. Consecutively, all three children developed clinical symptoms of neurodegenerative disease. Follow-up MRI and arylsulfatase A testing led to diagnosis of MLD. We conclude, that in young children who present with an acute/subacute demyelinating polyneuropathy, MLD is a differential diagnosis.

ABSTRACT

BACKGROUND: A human betaretrovirus has been characterized in patients with primary biliary cirrhosis (PBC). Uncontrolled studies using combination anti-retroviral therapy have reported significant biochemical and histological improvement. AIM: To conduct a double blind, randomized controlled trial as a proof of principal to link infection with PBC. METHODS: Fifty-nine patients with an alkaline phosphatase level>1.5 upper limits of normal stabilized on ursodeoxycholic acid therapy were randomized to either 300 mg zidovudine and 150 mg lamivudine B.I.D. or placebo for 6 months. RESULTS: None of the patients normalized alkaline phosphatase and no significant differences were observed in normalizing serum aminotransferase levels. Significant differences were observed in the antiviral versus placebo arms with improvements in serial alkaline phosphatase (p<0.04), ALT (p<0.03) and AST (p<0.04) as well as clinical score (p<0.02). After 6 months, 25% of patients in the placebo arm and 4% in the antiviral arm had evidence of virus in serum. CONCLUSIONS: The study endpoints for normalizing hepatic biochemistry were too stringent to show efficacy for zidovudine and lamivudine therapy despite the demonstrable impact on clinical and biochemical improvement. Accordingly, more potent anti-viral regimens will be required to confirm the efficacy of antiviral therapy in PBC patients with human betaretrovirus infection.
