    The authors present the results of a single centre study of 587 liver transplants performed in 522 adults during the period 1984-2002. Results have improved significantly over time due to better pre-, peri- and post-transplant care. One, five, ten and fifteen year actuarial survivals for the whole patient group are 81.2; 69.8; 58.9 and 51.2%. The high incidence of de novo tumors (12.3%), of cardiovascular diseases (7.5%) and of end-stage renal function (3.6%) should be further incentives to tailor the immunosuppression to the individual patient and to direct the attention of the transplant physician to the long-term quality of life of the liver recipient.

    Liver transplantation (LT) is an established lifesaving therapy for patients with cholestatic liver diseases, including primary cholestatic diseases, namely primary sclerosing cholangitis and primary biliary cirrhosis, as well as secondary forms of cholestatic liver disease, including those with cholestatic complications of LT needing a retransplant. Patients with cholestatic liver diseases can be transplanted for complications of end-stage liver disease or for disease-specific symptoms before the onset of end-stage liver disease. These patients should be regularly assessed. Patient survival after LT for cholestatic liver diseases is generally better than for other indications. PMID:26593299

    Hepatic epithelioid haemangioendotheliomas (HEHEs) are rare, low-grade vascular tumours. Five adults with HEHEs and one adult with a vascular tumour showing combined features of haemangioma and haemangioendothelioma underwent liver transplantation. Two HEHE patients had extrahepatic metastases at the time of transplantation. Median survival time following diagnosis was 10.7 years (range 40 months to 195 months). One patient needed resection of a HEHE in the breast 13 years post-transplantation. All six patients are surviving free from disease 22 to 166 months after transplantation (median 77 months). One HEHE-patient who had been treated for 8 years for vertebral and cerebral localisations is free of disease without immunosuppression 56 months after transplantation. We can conclude that liver transplantation is a valuable treatment for hepatic haemangioendothelioma, even in cases of extrahepatic localisation of the disease. PMID:15114438

    In 2015, there are a few absolute contraindications to liver transplantation. In adult patients, survival post-liver transplant is excellent, with 1-year survival rate >90% and 5-year survival rates >80% and predicted median allograft survival beyond 20 years. Patients with a Child-Turcotte Pugh score ≥9 or a model for end-stage liver disease (MELD) score >15 should be referred for liver transplantation, with patients who have a MELD score >17 showing a 1-year survival benefit with liver transplantation. A careful selection of hepatocellular cancer patients results in excellent outcomes, while consideration of extra-hepatic disease (reversible vs irreversible) and social support structures are crucial to patient assessment. Alcoholic liver disease remains a challenge, and the potential to cure hepatitis C virus infection together with the emerging issue of non-alcoholic fatty liver disease-associated chronic liver failure will change the landscape of the who in the years ahead. The when will continue to be determined largely by the severity of liver disease based on the MELD score for the foreseeable future. PMID:27062203

    Abstract The objective of this study was to evaluate the results of adult ABO-incompatible living donor liver transplantation (LDLT). ABO-incompatible LDLT is an aggressive treatment that crosses the blood-typing barrier for saving lives from liver diseases. Although graft and patient survival have been improved recently by various treatments, the results of adult ABO-incompatible LDLT require further evaluation. Two regimens were designed based on isoagglutinin IgG and IgM titers and the time course of immunological reactions at this institute. When isoagglutinin IgG and IgM titers were ≤64, liver transplantation was directly performed and rituximab (375 mg/m2) was administrated on postoperative day 1 (regimen I). When isoagglutinin titers were >64, rituximab (375 mg/m2) was administered preoperatively with or without plasmapheresis and boosted on postoperative day 1 (regimen II). Immunosuppression was achieved by administration of mycophenolate mofetil, tacrolimus, and steroids. Forty-six adult ABO-incompatible and 340 ABO-compatible LDLTs were performed from 2006 to 2013. The Model for End-Stage Liver Disease scores for ABO-incompatible recipients ranged from 7 to 40, with a median of 14. The graft-to-recipient weight ratio ranged from 0.61% to 1.61% with a median of 0.91%. The 1-, 3-, and 5-year survival rates were 81.7%, 75.7%, and 71.0%, respectively, for ABO-incompatible LDLT recipients, compared to 81.0%, 75.2%, and 71.5% for ABO-C recipients (P = 0.912). The biliary complication rate was higher in ABO-incompatible LDLT recipients than in the ABO-compatible recipients (50.0% vs 29.7%, P = 0.009). In the rituximab era, the blood type barrier can be crossed to achieve adult ABO-incompatible LDLT with survival rates comparable to those of ABO-compatible LDLT, but with more biliary complications.

    The aim of the study was to assess whether there is a difference in outcome after sequential or simultaneous revascularization during orthotopic liver transplantation (OLT) in terms of patient and graft survival, mortality, morbidity, and liver function. The study population consisted of 102 adult patients with primary full-size piggyback OLT transplanted between January 1998 and December 2001. In 71 patients (70%) the grafts were sequentially reperfused after completion of the portal vein anastomosis and subsequent arterial reconstruction was performed (sequential reperfusion [SeqR] group). In 31 patients (30%) the graft was reperfused simultaneously via the portal vein and hepatic artery (simultaneous reperfusion [SimR] group). Patient and graft survival at 1, 3, and 6 months and at 1 year did not differ between the SeqR group and the SimR group. The red blood cell (RBC) requirements were significantly higher in the SimR group (5.5 units; range 0-20) in comparison to the SeqR group (2 units; range 0-19) (P = 0.02). Apart from a higher number of biliary anastomotic complications and abdominal bleeding complications in the SimR group in comparison to the SeqR group (13% vs. 2% and 19% vs. 6%, respectively; P = 0.06), morbidity was not different between the groups. No differences between the groups were observed regarding the incidence of primary nonfunction (PNF), intensive care unit stay, and acute rejection. This was also true for the severity of rejections. Postoperative recuperation of liver function was not different between the groups. In conclusion, no advantage of either of the 2 reperfusion protocols could be observed in this analysis, especially with respect to the incidence of ischemic type biliary lesions (ITBL).

    Although there is an agreement that liver grafts from pediatric donors (PDs) should ideally be used for pediatric patients, there remain situations when these grafts are turned down for pediatric recipients and are then offered to adult recipients. The present study aimed to investigate the outcomes of using these grafts for liver transplantation (LT) in adult patients. Data from all patients undergoing LT between 2002 and 2014 were obtained from the United Network for Organ Sharing Standard Analysis and Research file. Adult recipients undergoing LT were divided into 2 groups: those receiving a pediatric liver graft (pediatric-to-adult group) and those receiving a liver graft from adult donors (adult-to-adult group). A separate subgroup analysis comparing the PDs used for adult recipients and those used for pediatric recipients was also performed. Patient and graft survival were not significantly different between pediatric-to-adult and adult-to-adult groups (P = 0.08 and P = 0.21, respectively). Hepatic artery thrombosis as the cause for graft loss was higher in the pediatric-to-adult group (3.6%) than the adult-to-adult group (1.9%; P < 0.001). A subanalysis looking at the pediatric-to-adult group found that patients with a predicted graft-to-recipient weight ratio (GRWR) < 0.8 had a higher 90-day graft loss rate than those with a GRWR ≥ 0.8 (39% versus 9%; P < 0.001). PDs used for adult recipients had a higher proportion of donors with elevated aspartate aminotransferase/alanine aminotransferase (20% vs. 12%; P < 0.001), elevated creatinine (11% vs. 4%; P < 0.001), donation after cardiac death donors (12% vs. 0.9%; P < 0.001), and were hepatitis B virus core positive (1% vs. 0.3%; P = 0.002) than PDs used for pediatric recipients. In conclusion, acceptable patient and graft survival can be achieved with the use of pediatric liver grafts in adult recipients, when these grafts have been determined to be inappropriate for

    AIM: To investigate the long-term outcome of recipients and donors of adult-to-adult living-donor liver transplantation (AALDLT) for acute liver failure (ALF). METHODS: Between January 2005 and March 2010, 170 living donor liver transplantations were performed at West China Hospital of Sichuan University. All living liver donor was voluntary and provided informed consent. Twenty ALF patients underwent AALDLT for rapid deterioration of liver function. ALF was defined based on the criteria of the American Association for the Study of Liver Diseases, including evidence of coagulation abnormality [international normalized ratio (INR) ≥ 1.5] and degree of mental alteration without pre-existing cirrhosis and with an illness of < 26 wk duration. We reviewed the clinical indications, operative procedure and prognosis of AALDTL performed on patients with ALF and corresponding living donors. The potential factors of recipient with ALF and corresponding donor outcome were respectively investigated using multivariate analysis. Survival rates after operation were analyzed using the Kaplan-Meier method. Receiver operator characteristic (ROC) curve analysis was undertaken to identify the threshold of potential risk factors. RESULTS: The causes of ALF were hepatitis B (n = 18), drug-induced (n = 1) and indeterminate (n = 1). The score of the model for end-stage liver disease was 37.1 ± 8.6, and the waiting duration of recipients was 5 ± 4 d. The graft types included right lobe (n = 17) and dual graft (n = 3). The mean graft weight was 623.3 ± 111.3 g, which corresponded to graft-to-recipient weight ratio of 0.95% ± 0.14%. The segment Vor VIII hepatic vein was reconstructed in 11 right-lobe grafts. The 1-year and 3-year recipient’s survival and graft survival rates were 65% (13 of 20). Postoperative results of total bilirubin, INR and creatinine showed obvious improvements in the survived patients. However, the creatinine level of the deaths was increased postoperatively

    Adult to adult living donor liver transplantation (AALDLT) was first preformed in the United States in 1997. The procedure was rapidly integrated into clinical practice, but in 2002, possibly due to the first widely publicized donor death, the number of living liver donors plummeted. The number of donors has since reached a steady plateau far below its initial peak. In this review we evaluate the current climate of AALDLT. Specifically, we focus on several issues key to the success of AALDLT: determining the optimal indications for AALDLT, balancing graft size and donor safety, assuring adequate outflow, minimizing biliary complications, and maintaining ethical practices. We conclude by offering suggestions for the future of AALDLT in United States transplantation centers. PMID:23239910

    This study investigated the feelings of living donors about adult-to-adult liver transplantation. We interviewed 18 donors about their feelings before and after transplantation using semistructured interviews and then conducted a content analysis of their responses. Before transplantation, many donors reported that they wanted recipients to live for the donor or his or her family, and there was no one else to donate. Many donors were not anxious, did not feel coerced, and did not consider donation dangerous. Some reported being excited at facing a new experience. Some said they would not mind whatever happens. Others were anxious or unsure about the operation. Diagnostic testing and preoperative blood banking were painful. Donors experienced increasing stress just before the operation. After transplantation, some donors verbalized feeling more grateful to others and that they gained maturity. Throughout the process, donors were concerned about their recipients. Our results suggest that donors might act for themselves or their family. It is important to recognize the varied responses of donors' feelings toward liver transplant recipients. PMID:18708830

    The Irish National Liver Transplant program commenced in 1993 in St. Vincent's University Hospital in Dublin. It is an adult-only program and is the only liver transplant program in Ireland. Pediatric recipients are referred to King's College Hospital in the United Kingdom. To date, almost 1000 adult liver transplants have been performed. Current 1-year patient survival is 93%, and 5-year survival is 79%. The program is fully funded by the government health service. There is a close collaboration with the United Kingdom Organ Donation and Transplant Directorate, and there is an arrangement for organ sharing for super-urgent transplants. Traditionally, organ donation rates have been high in Ireland. However, demand for liver transplant has increased over the past 20 years, and waiting lists are now lengthening. Deceased cardiac death donation is now being considered, but there are no plans for living related donor liver transplant. Donor coordinators have recently been appointed to the major hospitals in Ireland, and it is hoped that this initiative will lead to an increase in organ donation rates.

    Background Infants have the highest waitlist mortality of all liver transplant candidates. Deceased-donor split liver transplantation, a technique that provides both an adult and pediatric graft, may be the best way to decrease this disproportionate mortality. Yet concern for an increased risk to adult split recipients has discouraged its widespread adoption. We aimed to determine the current risk of graft failure in adult recipients following split liver transplantation. Study Design United Network for Organ Sharing (UNOS) data from 62,190 first-time adult recipients of deceased-donor liver transplants (1995–2010) were analyzed (889 split grafts). Bivariate risk factors (p<0.2) were included in cox proportional hazards models of the effect of transplant type on graft failure. Results Split liver recipients had an over-all hazard-ratio (HR) of graft failure of 1.26 (p<.001) compared to whole liver recipients. The split liver HR was 1.45 (p<.001) in the pre-MELD era (1995–2002), and 1.10 (p=.28) in the MELD era (2002–2010). Interaction analyses suggested an increased risk of split graft failure in Status 1 recipients and those given an exception for hepatocellular carcinoma (HCC). Excluding higher-risk recipients, split and whole grafts had similar outcomes (HR .94, p=.59). Conclusions The risk of graft failure is now similar between split and whole liver recipients in the vast majority of cases – demonstrating that the expansion of split liver allocation may be possible without increasing the overall risk of long-term graft failure in adult recipients. Further prospective analysis should examine if selection bias may account for the possible increase in risk for recipients with HCC or designated Status 1. PMID:23978530

    Adult polycystic liver disease (APLD) is a rare disorder of the liver parenchyma, the treatment of which is still controversial. Conservative surgery may have a significant morbidity and is often ineffective in the long run. Liver replacement may be indicated in case of incapacitating hepatomegaly. Patients (one male, five females) undergoing liver transplantation for symptomatic APLD is presented in this study. The particular nature of this series is the fact that successful transplantation was performed in all cases with preservation of the recipient's inferior vena cava and without use of veno-venous bypass despite massive hepatomegaly and previous extensive liver surgery (in three cases). There was minimal morbidity and no mortality. All patients have excellent quality of life with a median follow-up of 41 months (range: 12-58) as testified by a median Karnofsky score of 90% (range: 80-100%). PMID:15819798

    The study objectives were to determine whether the findings of the Adult-to-Adult Living Donor Liver Transplantation Cohort Study (A2ALL) reflect the U.S. national experience and to define risk factors for patient mortality and graft loss in living donor liver transplantation (LDLT). A2ALL previously identified risk factors for mortality after LDLT, which included early center experience, older recipient age, and longer cold ischemia time. LDLT procedures at 9 A2ALL centers (n = 702) and 67 non-A2ALL centers (n = 1664) from January 1998 through December 2007 in the Scientific Registry of Transplant Recipients database were analyzed. Potential predictors of time from transplantation to death or graft failure were tested using Cox regression. No significant difference in overall mortality between A2ALL and non-A2ALL centers was found. Higher hazard ratios (HRs) were associated with donor age (HR = 1.13 per 10 years, P = 0.0002), recipient age (HR = 1.20 per 10 years, P = 0.0003), serum creatinine levels (HR = 1.52 per loge unit increase, P < 0.0001), hepatocellular carcinoma (HR = 2.12, P<0.0001) or hepatitis C virus (HR = 1.18, P = 0.026), intensive care unit stay (HR = 2.52, P< 0.0001) or hospitalization (HR = 1.62, P < 0.0001) versus home, earlier center experience (LDLT case number 15: HR = 1.61, P < 0.0001, and a cold ischemia time >4.5 hours (HR = 1.79, P = 0.0006). Except for center experience, risk factor effects between A2ALL and non-A2ALL centers were not significantly different. Variables associated with graft loss were identified and showed similar trends. In conclusion, mortality and graft loss risk factors were similar in A2ALL and non-A2ALL centers. These analyses demonstrate that findings from the A2ALL consortium are relevant to other centers in the U.S. performing LDLT, and conclusions and recommendations from A2ALL may help to guide clinical decision making.

    Liver disease develops in one-third of patients with cystic fibrosis (CF). It is rare for liver disease to have its onset after 20 years of age. Lung disease, however, is usually more severe in adulthood. A retrospective analysis was performed on nine patients. Three patients required lung transplantation approximately a decade after liver transplant, and another underwent combined liver and lung transplants. Four additional patients with liver transplants are awaiting assessment for lung transplants. One patient is awaiting combined liver and lung transplants. With increased survival in CF, several patients may require more than single organ transplantation. PMID:27405894

    Liver transplantation has become an established curative treatment in adult patients with acute or chronic end-stage liver diseases. In pediatric cases the number of cadaveric donor livers is not sufficient and to overcome the shortage of appropriate-sized whole liver grafts, technical variants of liver transplantation have been practiced. Reduced-size cadaveric and split cadaveric allografts have become an important therapeutic option, expanding the availability of size-appropriate organs for pediatric recipients with terminal liver disease. The number of pediatric deaths awaiting liver transplantation has been reduced by the introduction of living-related liver transplantation, developed to overcome the shortage of suitable grafts for children. It is important for radiologists to know that children have distinct imaging of liver transplantation that distinguish them from adults. A multidisciplinary pediatric liver transplantation team should be skilled in pediatric conditions and in associated processes, risks and complications. Radiologists should know the common pediatric liver diseases that lead to liver transplantation, the anastomotic techniques and the expected postoperative imaging findings. The aim of this study is to illustrate the role of non-invasive imaging such us ultrasonography, color Doppler ultrasonography, multidetector computed tomography and magnetic resonance imaging in the evaluation of pediatric liver transplantation and in potential liver donors.

    Mesenchymal hamartomas of the liver (MHLs) in adults are rare and potentially premalignant lesions, which present as solid/cystic neoplasms. We report a rare case of orthotopic liver transplantation in a patient with a giant MHL. In 2013, a 34-year-old female sought medical advice after a 2-year history of progressive abdominal distention and respiratory distress. Physical examination revealed an extensive mass in the abdomen. Computed tomography (CT) of her abdomen revealed multiple liver cysts, with the diameter of largest cyst being 16 cm × 14 cm. The liver hilar structures were not clearly displayed. The adjacent organs were compressed and displaced. Initial laboratory tests, including biochemical investigations and coagulation profile, were unremarkable. Tumor markers, including levels of AFP, CEA and CA19-9, were within the normal ranges. The patient underwent orthotopic liver transplantation in November 2013, the liver being procured from a 40-year-old man after cardiac death following traumatic brain injury. Warm ischemic time was 7.5 min and cold ischemic time was 3 h. The recipient underwent classical orthotopic liver transplantation. The recipient operative procedure took 8.5 h, the anhepatic phase lasting for 1 h without the use of venovenous bypass. The immunosuppressive regimen included intraoperative induction with basiliximab and high-dose methylprednisolone, and postoperative maintenance with tacrolimus, mycophenolate mofetil, and prednisone. The recipient’s diseased liver weighed 21 kg (dry weight) and measured 41 cm × 32 cm × 31 cm. Histopathological examination confirmed the diagnosis of an MHL. The patient did not experience any acute rejection episode or other complication. All the laboratory tests returned to normal within one month after surgery. Three months after transplantation, the immunosuppressive therapy was reduced to tacrolimus monotherapy, and the T-tube was removed after cholangiography showed no abnormalities. Twelve months

    Mesenchymal hamartomas of the liver (MHLs) in adults are rare and potentially premalignant lesions, which present as solid/cystic neoplasms. We report a rare case of orthotopic liver transplantation in a patient with a giant MHL. In 2013, a 34-year-old female sought medical advice after a 2-year history of progressive abdominal distention and respiratory distress. Physical examination revealed an extensive mass in the abdomen. Computed tomography (CT) of her abdomen revealed multiple liver cysts, with the diameter of largest cyst being 16 cm × 14 cm. The liver hilar structures were not clearly displayed. The adjacent organs were compressed and displaced. Initial laboratory tests, including biochemical investigations and coagulation profile, were unremarkable. Tumor markers, including levels of AFP, CEA and CA19-9, were within the normal ranges. The patient underwent orthotopic liver transplantation in November 2013, the liver being procured from a 40-year-old man after cardiac death following traumatic brain injury. Warm ischemic time was 7.5 min and cold ischemic time was 3 h. The recipient underwent classical orthotopic liver transplantation. The recipient operative procedure took 8.5 h, the anhepatic phase lasting for 1 h without the use of venovenous bypass. The immunosuppressive regimen included intraoperative induction with basiliximab and high-dose methylprednisolone, and postoperative maintenance with tacrolimus, mycophenolate mofetil, and prednisone. The recipient's diseased liver weighed 21 kg (dry weight) and measured 41 cm × 32 cm × 31 cm. Histopathological examination confirmed the diagnosis of an MHL. The patient did not experience any acute rejection episode or other complication. All the laboratory tests returned to normal within one month after surgery. Three months after transplantation, the immunosuppressive therapy was reduced to tacrolimus monotherapy, and the T-tube was removed after cholangiography showed no abnormalities. Twelve months

    Abstract Development of organ transplantation is restricted by the discrepancy between the lack of donors and increasing number of patients. The outcome of pediatric donors transplanted into adult recipients especially with donation after circulatory death (DCD) pattern has not been well studied. The aim of this paper is to describe our experience of 3 successful DCD donor child-to-adult liver transplantations lately. Three DCD donors were separately 7, 5, and 8 years old. The ratio between donor graft weight and recipient body weight was 1.42%, 1.00%, and 1.33%, respectively. Ratio between the volume of donor liver and the expected liver volume was 0.65, 0.46, and 0.60. Splenectomy was undertaken for the second recipient according to the portal vein pressure (PVP) which was observed during the operation. Two out of 3 of the recipients suffered with acute kidney injury and got recovered after renal replacement therapy. The first recipient also went through early allograft dysfunction and upper gastrointestinal bleeding. The hospital course of the third recipient was uneventful. After 1 year of follow-up visit, the first and second recipients maintain good quality of life and liver function. The third patient was followed up for 5 months until now and recovered well. DCD child-to-adult liver transplantation should only be used for comparatively matched donor and recipient. PVP should be monitored during the operation. The short-term efficacy is good, but long-term follow-up and clinical study with large sample evaluation are still needed. PMID:26886643

    We examined the outcomes of adult intestinal transplants (ITx); isolated ITx vs. liver-intestinal transplants (L-ITx) were compared using the UNOS database (1987-2009). Of 759 ITx transplants in 687 patients, 463 (61%) were isolated and 296 (39%) were L-ITx. Patient survival for primary isolated ITx at one, three, and five yr was 84%, 66.7%, and 54.2%; and primary L-ITx was, 67%, 53.3%, and 46% (p = 0.0005). Primary isolated ITx graft survival at one, three, and five yr was 80.7%, 57.6%, 42.8%; primary L-ITx was 64.1%, 51%, 44.1% (p = 0.0003 at one, three yr, Wilcoxon test). For retransplants (n = 72), patient and graft survival for isolated ITx (n = 41) at five yr was 40% in era 1 (1987-2000) and 16% in era 2 (p = 0.47); for retransplanted L-ITx (n = 31), it improved from 14% to 64% in era 2 (p = 0.01). Cox regression: creatinine >1.3 mg/dL and pre-transplant hospitalization were negative predictors for outcome of both; bilirubin >1.3 mg/dL was a negative predictor for isolated ITx and donor age >40 yr for L-ITx. Isolated ITx should be considered prior to liver disease for adults with intestinal failure; L-ITx is preferable for retransplantation. PMID:22192061

    Discovery of non-invasive diagnostic and predictive biomarkers for acute rejection in liver transplant patients would help to ensure the preservation of liver function in the graft, eventually contributing to improved graft and patient survival. We evaluated selected cytokines and chemokines in the sera from liver transplant patients as potential biomarkers for acute rejection, and found that the combined detection of IL-10, IL-17, and CXCL10 at 1-2 weeks post-operation could predict acute rejection following adult liver transplantation with 97% specificity and 94% sensitivity.

    2016-09-01

    Liver transplantation (LT) activity started in Spain in 1984 and has exceeded 23,700 interventions, with more than 1000 transplants performed yearly. Every hospital needs official authorization to perform a LT, which implies the obligation to register all patients on the national waiting list. The Spanish National Transplant Organization (ONT) provides essential support for organ procurement, allocation, and management of the waiting list at a national level. Liver allocation is center-oriented as all available organs are referred to the ONT for the whole country. The allocation rules for LT are made according to disease severity after consensus among professionals from every transplant center and ratified by representatives of the regional health authorities. Authorization and location/distribution of transplant centers are regulated by the country (Spain) and by the different regions according to the Real Decreto 1723/2012. For a total population of 47,850,795 inhabitants, there are 24 centers for LT for adults (1 team/2 million people) and 5 for LT for children (1 team/9.5 million people). Nonbiliary cirrhosis, particularly alcohol- and hepatitis C virus-related cirrhosis (60%), and tumors, mainly hepatocellular carcinoma (19%), are the most common indications for LT in Spain. Unusual causes of LT include metabolic diseases like Wilson's disease, familial amyloid polyneuropathy and hyperoxaluria type I, polycystic kidney and liver disease, and some tumors (epithelioid hemangioendothelioma and neuroendocrine tumors). Important efforts are now being undertaken to improve the quality and transplantability of extended criteria livers, in particular those arising from DCD, which represent the greatest opportunity to expand the donor pool. These efforts have to be addressed to adapt the organ preservation procedures, be it through the application of regional perfusion in situ or the use of machine perfusion preservation ex situ.

    Although sexual functioning is an important facet of a living donor's quality of life, it has not received an extensive evaluation in this population. Using data from the Adult-to-Adult Living Donor Liver Transplantation Cohort Study, we examined donor sexual functioning across the donation process from the predonation evaluation to 3 months and 1 year after donation. Donors (n = 208) and a comparison group of nondonors (n = 155) completed self-reported surveys with specific questions on sexual desire, satisfaction, orgasm, and (for men) erectile function. Across the 3 time points, donor sexual functioning was lower at the evaluation phase and 3 months after donation versus 1 year after donation. In the early recovery period, abdominal pain was associated with difficulty reaching orgasm [odds ratio (OR), 3.98; 95% confidence interval (CI), 1.30-12.16], concerns over appearance were associated with lower sexual desire (OR, 4.14; 95% CI, 1.02-16.79), and not feeling back to normal was associated with dissatisfaction with sexual life (OR, 3.58; 95% CI, 1.43-8.99). Efforts to educate donors before the surgery and prepare them for the early recovery phase may improve recovery and reduce distress regarding sexual functioning. PMID:25779554

    Controversy exists regarding the best method for venous outflow reconstruction after live donor liver transplantation using right lobe grafts. Some authors advocate routine inclusion of the middle hepatic vein with the graft, whereas others favor a more selective approach. In this report, we examine the evolution of our decision making and technique of selective anterior venous segment reconstruction during live donor adult liver transplantation performed in 226 recipients. We have developed a simplified back-bench procedure using sequential-composite anastomosis using various vascular conduits with syndactylization to the right hepatic vein creating a single large-outflow anastomosis in the recipient. Conduits used include iliac artery or vein allograft, recanalized umbilical vein, cryopreserved iliac artery allograft, and 6-mm synthetic expanded polytetrafluoroethylene vascular graft. This technique can be performed quickly, safely, and under cold storage conditions and results in excellent outcome while minimizing donor risk. PMID:21980936

    Radiology is a key specialty within a liver transplant program. Interventional techniques not only contribute to graft and recipient survival but also allow appropriate patient selection and ensure that recipients with severe liver decompensation, hepatocellular carcinoma or portal hypertension are transplanted with the best chance of prolonged survival. Equally inappropriate selection for these techniques may adversely affect survival. Liver transplantation is a dynamic field of innovative surgical techniques with a requirement for interventional radiology to parallel these developments. This paper reviews the current practice within a major European center for adult and pediatric transplantation.

    Living donor liver transplantation has become an accepted procedure to overcome the shortage of adult donor organs. The aim of this study was to evaluate the usefulness of hepatobiliary scintigraphy in the diagnosis of complications after adult-to-adult living donor liver transplantation. We analysed 82 hepatobiliary scintigraphy studies performed using technetium-99m DISIDA in 60 adult patients (44 males, 16 females) who had been transplanted with a living donor's hepatic lobe (right lobe, 32; left lobe, 28). Indications for hepatobiliary scintigraphy were abnormal symptoms and/or liver function tests ( n=54) or suspected bile leak or biloma ( n=28). Median interval between transplantation and scintigraphy was 69 days (9 days to 23 months). Scintigraphic findings were classified into hepatic parenchymal dysfunction, total biliary obstruction, segmental biliary obstruction, bile leak and normal graft. Scintigraphic findings were confirmed by liver biopsy in 17 cases, and by radiological and clinical follow-up in 65 cases. There were 29 events relating to biliary complications (six total biliary obstructions, eight segmental biliary obstructions and 15 bile leaks) and 19 relating to non-biliary complications (15 cases of rejection, two of infection and two of vascular compromise) in 38 patients. Hepatobiliary scintigraphy provided the correct diagnosis in all eight segmental and five of six total biliary obstructions, and in all 15 cases of bile leak. Of the 19 non-biliary complications, 16 showed parenchymal dysfunction regardless of the aetiology and three showed total biliary obstruction on scintigraphy. All but three of 34 normally functioning grafts were normal on scintigraphy. The diagnostic sensitivity and specificity of scintigraphy for biliary obstruction in the 54 patients with abnormal symptoms or liver function tests were 93% (100% for segmental, 83% for total) and 88% (35/40), respectively. The sensitivity and specificity were each 100% (15/15, 13

    Background There has been little focus lately on operative techniques for full graft liver transplantation, and the standard technique is unclear. Methods An internet survey addressing the key technical issues was e-mailed to programme directors. Results Responses were obtained from 93 out of 128 (73%) directors contacted. Programmes performed a median of 60 (8–240) transplants per year. Maximum mean cold time of 13 ± 3 h and maximum median steatosis of 40% (15–90%) were tolerated. The inferior vena cava was preserved by 48% of centres all the time and 43% selectively. European centres used temporary portacaval shunting (42%) four times more often than USA programmes. Venous bypass was always used when not preserving the inferior vena cava by less than 25%, and used selectively by approximately 40% of centres. Portal vein anastomosis with room for expansion (88%), graft hepatic artery to native gastroduodenal/common hepatic artery bifurcation (57%) and bile duct-to-duct (47%) were the favoured techniques. Discussion A standard international operative technique for deceased donor liver transplantation does not exist, although there is a trend towards inferior vena cava preservation. Donor selection criteria were more homogenous across programmes. As suggested by the high response rate, there likely exists interest to investigate technical variations on an international scale.

    Background Thermodilution technique using a pulmonary artery catheter is widely used for the assessment of cardiac output (CO) in patients undergoing liver transplantation. However, the unclearness of the risk-benefit ratio of this method has led to an interest in less invasive modalities. Thus, we evaluated whether noninvasive bioreactance CO monitoring is interchangeable with thermodilution technique. Methods Nineteen recipients undergoing adult-to-adult living donor liver transplantation were enrolled in this prospective observational study. COs were recorded automatically by the two devices and compared simultaneously at 3-minute intervals. The Bland–Altman plot was used to evaluate the agreement between bioreactance and thermodilution. Clinically acceptable agreement was defined as a percentage error of limits of agreement <30%. The four quadrant plot was used to evaluate concordance between bioreactance and thermodilution. Clinically acceptable concordance was defined as a concordance rate >92%. Results A total of 2640 datasets were collected. The mean CO difference between the two techniques was 0.9 l/min, and the 95% limits of agreement were -3.5 l/min and 5.4 l/min with a percentage error of 53.9%. The percentage errors in the dissection, anhepatic, and reperfusion phase were 50.6%, 56.1%, and 53.5%, respectively. The concordance rate between the two techniques was 54.8%. Conclusion Bioreactance and thermodilution failed to show acceptable interchangeability in terms of both estimating CO and tracking CO changes in patients undergoing liver transplantation. Thus, the use of bioreactance as an alternative CO monitoring to thermodilution, in spite of its noninvasiveness, would be hard to recommend in these surgical patients. PMID:26017364

    Living donor liver transplantation (LDLT) has been widely used to treat end-stage liver disease with improvement in surgical technology and the application of new immunosuppressants. Vascular complications after liver transplantation remain a major threat to the survival of recipients. LDLT recipients are more likely to develop vascular complications because of their complex vascular reconstruction and the slender vessels. Early diagnosis and treatment are critical for the survival of graft and recipients. As a non-invasive, cost-effective and non-radioactive method with bedside availability, conventional gray-scale and Doppler ultrasonography play important roles in identifying vascular complications in the early postoperative period and during the follow-up. Recently, with the detailed vascular tracing and perfusion visualization, contrast-enhanced ultrasound (CEUS) has significantly improved the diagnosis of postoperative vascular complications. This review focuses on the role of conventional gray-scale ultrasound, Doppler ultrasound and CEUS for early diagnosis of vascular complications after adult LDLT. PMID:26819527

    Liver transplantation as a curative treatment method can be used for selected primary liver tumours, in particular for hepatocellular carcinoma and rather rare semi-malignant tumours such as epithelioid hemangioendothelioma, further for infiltration of liver by metastatic neuroendocrine tumours (provided that metastases are only located in the liver and the primary tumour was removed) and for benign tumours (hemangiomas and adenomas) with oppression symptoms and size progression. Cholangiocarcinoma is not indicated for liver transplantation at the CKTCH Brno. In recent years liver transplants for hepatocellular carcinoma have increased and hepatocellular carcinoma has also been more frequently found ex post, in the explanted livers. Liver transplantation is indicated in selected patients with a good chance of long-term survival after liver transplantation (a generally accepted limit is 5 year survival of 50 % after transplantation). By 20 March 2015 there were liver transplants carried out on 38 patients - in 25 of them was hepatocellular carcinoma diagnosed before transplantation and in 13 it was found in the liver explants. 5 year survival following transplantation is reached by 53 % of this cohort. 32 % patients suffered from chronic hepatitis C. The longest surviving (32 years) patient at CKTCH Brno had liver transplanted for a big fibrolamellar hepatocellular carcinoma, which points to the prognostic significance of tumour histology: the criterion only considered in some indication schemes for practical reasons. Benign liver tumours (adenomatosis, cystadenoma, hemangioma with oppression symptoms) are rather rare indications and the transplantation results are favourable. 4 patients underwent transplantation for infiltration of liver by carcinoid, tumour recurrence occurred in one.

    The purpose of this study was to evaluate the efficacy of percutaneous endovascular techniques for the treatment of hepatic artery stenosis (HAS) occurring after liver transplantation (LT) in adult and pediatrics patients. From February 2003 to March 2009, 25 patients (15 adults and 10 children) whose developed HAS after LT were referred to our interventional radiology unit. Technical success was achieved in 96% (24 of 25) of patients. Percutaneous transluminal angioplasty (PTA) was performed in 13 patients (7 children), and stenting was performed in 11 patients (2 children). After the procedure, all patients were followed-up with liver function tests, Doppler ultrasound, and/or computed tomography. Mean follow-up was 15.8 months (range 5 days to 58 months). Acute hepatic artery thrombosis occurred immediately after stent deployment in 2 patients and was successfully treated with local thrombolysis. One patient developed severe HA spasm, which reverted after 24 h. After the procedure, mean trans-stenotic pressure gradient decreased from 30.5 to 6.2 mmHg. Kaplan-Meyer curve of HA primary patency was 77% at 1 and 2 years. During the follow-up period, 5 patients (20%) had recurrent stenosis, and 2 patients (8.3%) had late thrombosis. Two of 7 patients with stenosis/thrombosis underwent surgical revascularization (n = 1) and liver retransplantation (n = 1). Six (25%) patients died during follow-up, but overall mortality was not significantly different when comparing patients having patent hepatic arteries with those having recurrent stenosis/thrombosis. There were no significant differences in recurrent stenosis/thrombosis and mortality comparing patients treated by PTA versus stenting and comparing adult versus pediatric status. Percutaneous interventional treatment of HAS in LT recipients is safe and effective and decreases the need for surgical revascularization and liver retransplantation. However, the beneficial effects for survival are not clear, probably because

    Kidney transplantation after liver transplantation (KALT) offers longer survival and a better quality of life to liver transplantation recipients who develop chronic renal failure. This article aimed to discuss the efficacy and safety of KALT compared with other treatments. The medical records of 5 patients who had undergone KALT were retrospectively studied, together with a literature review of studies. Three of them developed chronic renal failure after liver transplantation because of calcineurin inhibitor (CNI)-induced nephrotoxicity, while the others had lupus nephritis or non-CNI drug-induced nephrotoxicity. No mortality was observed in the 5 patients. Three KALT cases showed good prognoses, maintaining a normal serum creatinine level during entire follow-up period. Chronic rejection occurred in the other two patients, and a kidney graft was removed from one of them. Our data suggested that KALT is a good alternative to dialysis for liver transplantation recipients. The cases also indicate that KALT can be performed with good long-term survival. PMID:27498586

    Acute liver failure (ALF) is defined by the presence of coagulopathy (International Normalized Ratio ≥ 1.5) and hepatic encephalopathy due to severe liver damage in patients without pre-existing liver disease. Although the mortality due to ALF without liver transplantation is over 80%, the survival rates of patients have considerably improved with the advent of liver transplantation, up to 60% to 90% in the last two decades. Recent large studies in Western countries reported 1, 5, and 10-year patient survival rates after liver transplantation for ALF of approximately 80%, 70%, and 65%, respectively. Living donor liver transplantation (LDLT), which has mainly evolved in Asian countries where organ availability from deceased donors is extremely scarce, has also improved the survival rate of ALF patients in these regions. According to recent reports, the overall survival rate of adult ALF patients who underwent LDLT ranges from 60% to 90%. Although there is still controversy regarding the graft type, optimal graft volume, and ethical issues, LDLT has become an established treatment option for ALF in areas where the use of deceased donor organs is severely restricted.

    HCV-related cirrhosis represents the leading indication for liver transplantation in the Western countries. HCV reinfection after liver transplantation occurs in virtually all patients transplanted for HCV-related liver disease Histological evidence of chronic HCV infection develops in 50 to 90 % of patients by 12 months after liver transplantation, and cirrhosis occurs in about 20 % of patients within 5 years after transplant. Several studies have evaluated host, viral, and transplant-related factors that might be associated with the severity of HCV recurrence. Among host factors, immunosuppression is one of the major factors that accounts for accelerated HCV recurrence and it has been an area of extensive research and controversy. Donor age, steatosis, and immunogenetic factors are also relevant in determining the outcome in patients transplanted for HCV-related cirrhosis. A major step to prevent complications of HCV recurrence related to the rapid fibrosis is the posttransplant antiviral treatment. Two strategies have been tried: pre-emptive or other strategies as soon as possible after liver transplantation or elective therapy once there is histological evidence of recurrent hepatitis C. Retransplantation due to graft failure from recurrent hepatitis C is rarely an option in the era of organ shortage as it is associated with poor outcome, but many case needs to be considered early in the evolution of disease. New antivirals may change the outcome dramatically of patients transplanted for HCV cirrhosis. PMID:22829333

    Women constitute >30% of patients undergoing liver transplantation (orthotopic liver transplantation, OLT) and about 8% are of reproductive age, and 5% are pediatric females who will mostly survive into adulthood and will consider pregnancy. Although pregnancy in OLT recipients is associated with an increased incidence of hypertension, preeclampsia, anemia, preterm deliveries, and cesarean section, acute rejection and liver allograft loss do not appear to be increased and pregnancy-related maternal death is uncommon. The incidence of structural malformations in the newborn of liver transplant recipients is reported to be 4.4%, which is similar to the rate of 3-5% in the US general population. Patients are advised to defer conception for at least 1-2 years after OLT, while maintaining effective contraception. Pregnancy after OLT usually results in a favorable maternal and neonatal outcome when there is coordinated pre- and perinatal care by a multidisciplinary team composed of obstetric-gynecologists, and a transplant team.

    Background After whole graft orthotopic liver transplantation (OLT), adaptation of the large grafts' volume to recipient weight is widely accepted despite the paucity of evidence on this subject. Methods Thirty nine patients with GRWR > 2.5% were included in this study and subsequently divided into two groups with 3 ≥ GRWR > 3%. Patients had CT scans at three predetermined time points after OLT used for measuring the liver volume. The objective of this study is to evaluate the volumetric changes of whole large liver grafts after adult OLT. Results At LT, the mean graft recipient body weight ratio (GRWR) was 3.1 ± 0.4%. The mean liver weight was 1881 ± 68 g at LT, 2014 ± 99 ml at one week, 1725 ± 126 ml at 3 months, and 1632 ± 117 (ml) at >6 months. There is an initial increase at 1 week after LT and a subsequent decrease of liver volume on later measurements. None of the late volume measurements were significantly different from the initial graft volume at liver transplant in pair wise comparisons ANOVA repeated measures (p > 0.05). Similarly, the mean GRWR did not change significantly between the initial calculation at transplantation date and the subsequent measurements during the different study time points (F = 0.04, p = 0.96) with a mean of 3.1% (95% CI = 2.2–4.2). AUC ROC discriminated a cutoff of 3% for the initial GRWR above which grafts tend to decrease in size over time (c statistics = 0.74, p = 0.036). In a Clustered ANOVA repeated measures, there was no significant difference in the changes of liver volume between both groups. However, patients with GRWR > 3 showed a trend towards a latent reduction in volume over the tracing period. There was a tendency, but none significant; towards a higher bilirubin, AST, ALT levels over the first postoperative days in recipients with GRWR > 3. Conclusion Large grafts do not significantly decrease in size. Nonetheless, grafts weighing >3% of the GRWR show a different trend

    Background As an important means to tackle the worldwide shortage of liver grafts, adult-adult living donor liver transplantation (A-ALDLT) is the most massive operation a healthy person could undergo, so donor safety is of prime importance. However, most previous research focused on recipients, while complications in donors have not been fully described or investigated. Material/Methods To investigate donor safety in terms of postoperative complications, the clinical data of 356 A-ALDLT donors in our center from January 2002 to September 2015 were retrospectively analyzed. These patients were divided into a pre-2008 group (before January 2008) and a post-2008 group (after January 2008). Donor safety was evaluated with regard to the type, frequency, and severity of postoperative complications. Results There were no donor deaths in our center during this period. The overall complication rate was 23.0% (82/356). The proportion of Clavien I, II, III, and IV complications was 51.2% (42/82), 25.6% (21/82), 22.0% (18/82), and 1.2% (1/82), respectively. In all the donors, the incidence of Clavien I, II, III, and IV complications was 11.8% (42/356), 5.9% (21/356), 5.1% (18/356), and 0.3% (1/356), respectively. The overall complication rate in the post-2008 group was significantly lower than that in the pre-2008 group (18.1% (41/227) vs. 32.6% (42/129), P<0.01). Biliary complications were the most common, with an incidence of 8.4% (30/356). Conclusions The risk to A-ALDLT donors is controllable and acceptable with improvement in preoperative assessment and liver surgery. PMID:27178367

    In previous decades, pediatric liver transplantation has become a state-of-the-art operation with excellent success and limited mortality. Graft and patient survival have continued to improve as a result of improvements in medical, surgical and anesthetic management, organ availability, immunosuppression, and identification and treatment of postoperative complications. The utilization of split-liver grafts and living-related donors has provided more organs for pediatric patients. Newer immunosuppression regimens, including induction therapy, have had a significant impact on graft and patient survival. Future developments of pediatric liver transplantation will deal with long-term follow-up, with prevention of immunosuppression-related complications and promotion of as normal growth as possible. This review describes the state-of-the-art in pediatric liver transplantation. PMID:19222089

    Liver transplantation (LT) is a well-accepted procedure for end-stage liver disease in Germany. In 2015, 1489 patients were admitted to the waiting list (including 1308 new admissions), with the leading etiologies being fibrosis and cirrhosis (n = 349), alcoholic liver disease (n = 302), and hepatobiliary malignancies (n = 220). Organ allocation in Germany is regulated within the Eurotransplant system based on urgency as expressed by the Model for End-Stage Liver Disease score. In 2015, only 894 LTs (n = 48 from living donors) were performed at 23 German transplant centers, reflecting a shortage of organs. Several factors may contribute to the low number of organ donations. The German transplant legislation only accepts donation after brain death (not cardiac death), whereas advances in neurosurgery and a more frequently requested "palliative care" approach render fewer patients suitable as potential donors. The legislation further requires the active consent of the donor or first-degree relatives before donation. Ongoing debates within the German transplant field address the optimal management of patients with alcoholic liver cirrhosis, hepatocellular carcinoma (HCC), and cholangiocarcinoma and measures to increase living donor transplantations. As a result of irregularities at mainly 4 German transplant centers that were exposed in 2012, guiding principles updated by the German authorities have since implemented strict rules (including internal and external auditing, the 8-eyes principle, mandatory repeated testing for alcohol consumption) to prohibit any manipulations in organ allocation. In conclusion, we will summarize important aspects on the management of LT in Germany, discuss legal and organizational aspects, and highlight challenges mainly related to the relative lack of organ donations, increasing numbers of extended criteria donors, and the peculiarities of the recipient patients.

    Liver transplantation was the product of 5 interlocking themes. These began in 1958-59 with canine studies of then theoretical hepatotrophic molecules in portal venous blood (Theme I) and with the contemporaneous parallel development of liver and multivisceral transplant models (Theme II). Further Theme I investigations showed that insulin was the principal, although not the only, portal hepatotrophic factor. In addition to resolving long-standing controversies about the pathophysiology of portacaval shunt, the hepatotrophic studies blazed new trails in the regulation of liver size, function, and regeneration. They also targeted inborn metabolic errors (e.g. familial hyperlipoproteinemia) whose palliation by portal diversion presaged definitive correction with liver replacement. Clinical use of the Theme II transplant models depended on multiple drug immunosuppression (Theme III, Immunology), guided by an empirical algorithm of pattern recognition and therapeutic response. Successful liver replacement was first accomplished in 1967 with azathioprine, prednisone, and ALG. With this regimen, the world’s longest surviving liver recipient is now 40 years postoperative. Incremental improvements in survival outcome occurred (Theme IV) when azathioprine was replaced by cyclosporine (1979) which was replaced in turn by tacrolimus (1989). However, the biologic meaning of alloengraftment remained enigmatic until multilineage donor leukocyte microchimerism was discovered in 1992 in long surviving organ recipients. Seminal mechanisms were then identified (clonal exhaustion-deletion and immune ignorance) that linked organ engraftment and the acquired tolerance of bone marrow transplantation and eventually clarified the relationship of transplantation immunology to the immunology of infections, neoplasms, and autoimmune disorders.

    Background Biliary atresia (BA) is a rare cholestatic disease of infancy. Kasai portoenterostomy and liver transplantation (LT) are the two sequential treatment options. An increasing number of patients survive into adulthood. Little is known about their health-related quality of life (HRQOL). This study aims to compare HRQOL of transplanted and nontransplanted patients in a cohort of young adult BA survivors. Patients and Methods RAND-36 and Liver Disease Index Score (LDSI) questionnaires were sent to eligible adult patients with BA. Clinical characteristics were obtained from the NeSBAR (Netherlands Study group on Biliary Atresia Registry) and the national pediatric LT database. RAND-36 domain and summary scores were compared with those of an age-matched Dutch reference group. The correlations between several clinical variables and HRQOL were analyzed. Results Mean RAND-36 domain and summary scores of transplanted (n = 15) and nontransplanted (n = 25) patients with BA (response 74%) were similar to the reference scores, with the exception of a decreased general health perception in nontransplanted patients (63 ± 21 vs. 75 ± 17; [p < 0.001], particularly in females. RAND-36 domain and summary scores were not significantly correlated to age at LT, time since LT, serum bilirubin, aspartate amino transferase or albumin levels, but were moderately to strongly correlated to LDSI total scores (r values 0.35-0.77). Conclusions Overall, young adult patients with BA have a HRQOL similar to an age-matched reference group. However, general health perception of nontransplanted patients, particularly of females, was decreased. HRQOL is correlated to liver disease symptoms but not to liver biochemistry parameters. Nontransplanted females and patients suffering from liver disease-associated symptoms may be a target for tailored supportive interventions. PMID:26018212

    Polycystic liver disease (PLD) may provoke massive hepatomegaly and severe physical and social handicaps. Data on orthotopic liver transplantation (OLT) for PLD are rare and conflicting. Conservative surgery (resection or fenestration) is indicated for large single cysts, but its value for small diffuse cysts is questionable. In addition, conservative surgery is not devoid of morbidity and mortality. OLT offers the prospect of a fully curative treatment, but controversy remains because those patients usually have preserved liver function. Thus, we reviewed our experience with OLT for PLD. Sixteen adult women underwent OLT for small diffuse PLD between 1990 and 1999. Mean age was 45 years (range, 34 to 56 years). Fourteen patients had combined liver and kidney cystic disease, but only 1 patient required combined liver and kidney transplantation, whereas 13 patients underwent OLT alone. Two patients had isolated PLD. Indications for transplantation were massive hepatomegaly causing physical handicaps (n = 16), social handicaps (n = 16), malnutrition (n = 4), and cholestasis and/or portal hypertension (n = 5). OLT caused no technical difficulty in 15 of 16 patients (surgery duration, 6.8 hours; range, 5 to 8 hours), with blood transfusions of 7.9 units (range, 0 to 22 units). One patient who underwent attempted liver-mass reduction pre-OLT died of bleeding and pulmonary emboli. Native liver weight was 10 to 20 kg. Posttransplantation immunosuppression consisted of cyclosporine or FK506, azathioprine, and steroids (discontinued at 3 months). Morbidity included biliary stricture (2 patients), revision for bleeding and hepatitis (1 patient), pneumothorax and subphrenic collection (1 patient), and tracheostomy (1 patient). One patient died of lung cancer 6 years posttransplantation. Both patient and graft survival rates are 87.5% (follow-up, 3 months to 9 years). Of 15 patients who underwent OLT alone, only 1 patient needed a kidney transplant 4 years after OLT. Kidney

Despite the significant advances occurred in bariatric medicine, obesity is still considered a relative contraindication to liver transplantation (LT). The main aim of this review is to appraise the literature on the outcomes of OPs undergoing LT, treatments that might reduce their weight before, during or after surgery, and discuss some of the controversies and limitations of the current knowledge with the intent of highlighting areas where future research is needed.

    NG2-expressing cells are a population of periportal vascular stem/progenitors (MLpvNG2+ cells) that were isolated from healthy adult mouse liver by using a “Percoll-Plate-Wait” procedure. We demonstrated that isolated cells are able to restore liver function after transplantation into a cirrhotic liver, and co-localized with the pericyte marker (immunohistochemistry: PDGFR-β) and CK19. Cells were positive for: stem cell (Sca-1, CD133, Dlk) and liver stem cell markers (EpCAM, CD14, CD24, CD49f); and negative for: hematopoietic (CD34, CD45) and endothelial markers (CD31, vWf, von Willebrand factor). Cells were transplanted (1 × 106 cells) in mice with diethylnitrosamine-induced cirrhosis at week 6. Cells showed increased hepatic associated gene expression of alpha-fetoprotein (AFP), Albumin (Alb), Glucose-6-phosphatase (G6Pc), SRY (sex determining region Y)-box 9 (Sox9), hepatic nuclear factors (HNF1a, HNF1β, HNF3β, HNF4α, HNF6, Epithelial cell adhesion molecule (EpCAM), Leucine-rich repeated-containing G-protein coupled receptor 5-positive (Lgr5) and Tyrosine aminotransferase (TAT). Cells showed decreased fibrogenesis, hepatic stellate cell infiltration, Kupffer cells and inflammatory cytokines. Liver function markers improved. In a cirrhotic liver environment, cells could differentiate into hepatic lineages. In addition, grafted MLpvNG2+ cells could mobilize endogenous stem/progenitors to participate in liver repair. These results suggest that MLpvNG2+ cells may be novel adult liver progenitors that participate in liver regeneration. PMID:26905303

Although important, this topic is underrepresented in the current literature. With an increased frequency of fast tracking in LT, efficient intra- and postoperative analgesia are undergoing changes. We herein review the current literature, compare the benefits and disadvantages of the therapeutic options, and make recommendations based on the current literature and clinical experience.

    Acute rejection after liver transplantation occurs in one-third of all recipients and can be managed with conventional rejection therapy in the majority of cases. In rare instances, patients with severe acute rejection may be refractory to or have contraindications for conventional therapies. This case series evaluates the role of local allograft irradiation (LAI) as an adjunct for patients with rejection that is refractory to or contraindicated for conventional therapies. Additionally, the literature on the use of radiation therapy for reversing rejection in solid organ transplantation is reviewed. Five patients underwent 9 LAI treatments: 2 had refractory rejection, and 1 each had a malignancy, a concurrent life-threatening infection, and serum sickness with antibody therapy. Conventional rejection therapies included steroids, calcineurin inhibitors, and antithymocyte globulin. LAI consisted of 3 cycles of 1.5 Gy directed toward the liver allograft. Two of the 5 patients remained alive with excellent graft function. Six of the 9 treatments were successful in rescuing the liver allograft (reversing the rejection episode). Treatment success was associated with lower pretreatment serum bilirubin levels and higher pretreatment alanine aminotransferase levels. Compared with patients with immunosuppression-responsive severe acute rejection, those requiring LAI trended toward a later onset of first rejection. In conclusion, local irradiation of liver allografts can be a useful adjunct in patients for whom conventional options have been exhausted or cannot be used. The ability of LAI to reverse allograft dysfunction and promote patient survival appears to be greatest before the onset of severe cholestatic injury. PMID:25287272

    Primary sclerosing cholangitis (PSC) recurs in 15%-25% of patients transplanted for PSC. In the United States, PSC transplant patients are more likely to receive an organ from a living donor (LD) than patients without PSC. Our aims were to (1) compare risk of PSC recurrence in LD versus deceased donor recipients and (2) identify risk factors for PSC recurrence. There were 241 living donor liver transplantations (LDLTs) and 65 deceased donor liver transplantation (DDLT) patients transplanted between 1998 and 2013 enrolled in the Adult-to-Adult Living Donor Liver Transplantation Cohort Study who were evaluated. PSC recurrence risk for LDLT and DDLT recipients was compared using Kaplan-Meier survival curves and log-rank tests. Cox models were used to evaluate PSC risk factors. Overall PSC recurrence probabilities were 8.7% and 22.4% at 5 and 10 years after liver transplantation (LT), respectively. The risk of PSC recurrence was not significantly different for DDLT versus LDLT recipients (P = 0.36). For DDLT versus LDLT recipients, unadjusted 5- and 10-year PSC recurrence was 9.4% versus 9.5% and 36.9% versus 21.1%. Higher laboratory Model for End-Stage Liver Disease (MELD) score at LT, onset of a biliary complication, cholangiocarcinoma, and higher donor age were associated with increased risks of PSC recurrence: for MELD (hazard ratio [HR] = 1.06; 95% confidence interval [CI] 1.02-1.10 per MELD point, P = 0.002); for biliary complication (HR, 2.82; 95% CI, 1.28-6.25; P = 0.01); for cholangiocarcinoma (HR, 3.98; 95% CI, 1.43-11.09; P = 0.008); for donor age (per 5-years donor age; HR, 1.17; 95% CI, 1.02-1.35; P = 0.02). Factors not significantly associated with PSC recurrence included the following: first-degree relative donor (P = 0.11), post-LT cytomegalovirus infection (P = 0.38), and acute rejection (P = 0.22). Risk of recurrent PSC was not significantly different for DDLT and LDLT recipients. Biliary complications

    Liver transplantation (LT) services in the United Kingdom are provided by 7 designated transplant centers for a population of approximately 64 million. The number of deceased organ donors has grown, and in 2014-2015 it was 1282 (570 donation after circulatory death and 772 donation after brain death). Donor risk is increasing. In 2014-2015, there were 829 LTs from deceased and 38 from living donors. The common causes for transplantation are liver cell cancer, viral hepatitis, and alcohol-related liver disease. Livers are allocated first nationally to super-urgent listed patients and then on a zonal basis. The United Kingdom will be moving toward a national allocation scheme. The median interval between listing and transplantation is 152 days for adults awaiting their first elective transplant. Of the adults listed for the first elective transplant, 68% underwent transplantation at < 1 year; 17% are waiting; and 4% and 11% were removed or died, respectively. The 1- and 5-year adult patient survival rate from listing is 81% and 68%, respectively, and from transplantation is 92% and 80%, respectively. The transplant program is funded through general taxation and is free at the point of care to those who are eligible for National Health Service (NHS) treatment; some have to pay for medication (up to a maximum payment of US $151/year). The competent authority is the Human Tissue Authority which licenses donor characterization, retrieval, and implantation; transplant units are commissioned by NHS England and NHS Scotland. National Health Service Blood and Transplant (NHSBT) promotes organ donation, maintains the organ donor register, obtains consent, and undertakes donor characterization and offering. NHSBT also maintains the national waiting list, develops and applies selection and allocation policies, monitors outcomes, and maintains the UK National Transplant Registry and commissions a national organ retrieval service.

    Adult liver has the unusual ability to fully regenerate after injury. Although regeneration is accomplished by the division of mature hepatocytes, the replicative potential of these cells is unknown. Here, the replicative capacity of adult liver cells and their medical usefulness as donor cells for transplantation were investigated by transfer of adult mouse liver cells into transgenic mice that display an endogenous defect in hepatic growth potential and function. The transplanted liver cell populations replaced up to 80 percent of the diseased recipient liver. These findings demonstrate the enormous growth potential of adult hepatocytes, indicating the feasibility of liver cell transplantation as a method to replace lost or diseased hepatic parenchyma.

    Although sexual functioning is an important facet of living donor quality of life, it has not received extensive evaluation in this population. Using data from the Adult-to-Adult Living Donor Liver Transplantation Cohort Study, we examined donor sexual functioning across the donation process from the predonation evaluation to 3 months and 1 year postdonation. Donors (n=208) and a comparison group of non-donors (n=155) completed self-reported surveys with specific questions on sexual desire, satisfaction, orgasm, and (for men) erectile function. Across the three time points, donor sexual functioning was lower at the evaluation phase and 3 months postdonation than at one year postdonation. In the early recovery period, abdominal pain was associated with difficulty reaching orgasm (OR = 3.98, 95% CI 1.30–12.16), concerns over appearance with lower sexual desire (OR = 4.14, 95% CI 1.02–16.79), and not feeling back to normal was associated with dissatisfaction with sexual life (OR 3.58, 95% CI 1.43–8.99). Efforts to educate donors before the surgery and prepare them for the early recovery phase may improve recovery and reduce distress regarding sexual functioning. PMID:25779554

    Patients with end stage liver disease (ESLD) have complex problems such as cirrhotic cardiomyopathy, coronary artery disease, hepatopulmonary syndrome (HPS), portopulmonary hypertension (POPH), hepatic encephalopathy, intracranial hypertension, (ICP), left ventricular outflow tract obstruction (LVOTO), high Model of end liver disease (MELD) scores, hyponatremia, and coagulopathies. The anesthesia management for liver transplantation can be very complex, dynamic and challenging. Anesthesia agents affect hepatic blood flow and anesthetic drug distribution, metabolism and elimination maybe altered in end stage liver disease. Other non-anesthetic agents such as nitric oxide, epoprosterenol, THAM, hypertonic saline, fibrinogen concentrates, fresh frozen plasma, platelets, packed red blood cells, recombinant plasminogen activator, calcium chloride, epinephrine etc. may play a vital role in the perioperative management of these patients. Intraoperative hemostasis and coagulation management can be very arduous as these patients may bleed or be at risk for thrombosis. Monitoring modalities such as Thromboelastography (TEG), Transcranial Doppler (TCD), Transesophageal Echocardiography (TEE), Bispectral Index (BIS) and Optic Nerve Sheath Diameter (ONSD) ultrasound play a significant role in various circumstances. Surgical techniques include complete or partial occlusion of the inferior vena cava (IVC) with or without use of venovenous bypass (VVBP) or portocaval shunts. Post reperfusion syndrome (PRS) is a crucial event in this procedure, where patients may experience arrhythmia and/or cardiac arrest. Anesthetic handling of this phase has been recapitulated in detail. Provision of anesthesia services to the living liver transplant donor and pain management has been outlined. PMID:26118926

    Over 1700 liver transplantations (LTs) are performed annually in Brazil. In absolute terms, the country performs more LT surgeries than anywhere else in Latin America and is third worldwide. However, due to its increasing population and inadequate donor organ supply, the country averages 5-10 LTs per million population, far lower than required. There is a marked heterogeneity in organ donation and LT activity throughout the country. Access to LT in the underprivileged North, Midwest, and Northeast regions of Brazil is scarce. Major challenges for the future of LT in Brazil will be to increase organ donation and access to LT. The reduction of those geographical disparities in donation, organ procurement, and LT due to political and financial constraints is of utmost importance.

    Background: There is limited clinical evidence evaluating the correlation between immunosuppressant monitoring practice and transplant outcomes. Objective: To assess current practice of tacrolimus trough monitoring in early post-operative period following liver transplantation (LT), and its impact on outcomes. Methods: The duration to trough levels (DTT) were calculated in patients undergoing primary LT. The impact of variability in DTT on graft rejection episodes, serum tacrolimus level and renal function was assessed. These results were converted into a drug level estimation tool, which was validated in a prospective cohort of patients. Results: 2946 events in 274 patients were evaluated. The median DTT was 7:19 hrs (range: 27 min to 19:38 hrs). In 72% (2140 events) of the occasions, DTT was <8 hrs. There was a significant (p=0.022) correlation between DTT and tacrolimus level. Despite clinical decisions were taken to modify the dose of tacrolimus based on trough level, neither did DTT affect the average creatinine levels (p=0.923), nor the variability in DTT did affect acute rejection (p=0.914, and 0.712, respectively). A dose estimation tool was developed and applied to validation cohort (n=612), and returned a moderate R2 value of 0.50. Conclusion: There is a significant variation in the “real world” monitoring of tacrolimus with DTT in majority of measurements falling below recommendations; reassuringly, this did not lead to adverse transplant sequelae.

    BACKGROUND In South Korea, which has a high incidence of gastric cancer, the most common de novo malignancy associated with liver transplantation is gastric cancer. This study sought to identify clinicopathologic characteristics in gastric cancer patients after liver transplantation, and to help manage these cases. MATERIAL AND METHODS We investigated gastric cancer patients after liver transplantation at Asan Medical Center. We analyzed sex, age, cause of liver transplantation, initiating immunosuppressant, pre-transplantation gastric fibroscopy findings, time interval between transplantation and gastric cancer occurrence, follow-up period, existence of gastric cancer screening, Helicobacter pylori infection, family cancer history, gastric cancer treatment, cancer location, size of tumor, macroscopic gross type, WHO histologic type, Lauren's classification, TNM stage, and survival. RESULTS Of 2968 adult liver transplantation patients at our hospital, 19 were diagnosed with gastric cancer. The mean age at the time of gastric cancer diagnosis was 60.2±6.8 (46-71) years and mean time interval between liver transplantation and diagnosis of gastric cancer was 56.0±30.7 (3.20-113) months. Endoscopic submucosal dissection was done for 10 patients, 4 of whom underwent surgical resection. Surgical resection as an initial treatment was done in 8 patients. One patient received chemotherapy first. The standard incidence ratio of gastric cancer in these patients was 1036 per 100 000 persons (95% CI, 623.7-1,619) in men and 318.9 per 100 000 (95% CI, 4.170-1,774) in women. CONCLUSIONS For long-term survival of liver transplant patients, early detection of de novo cancer is necessary. Therefore, annual screening for gastric cancer after liver transplantation is needed, especially in areas where the incidence of gastric cancer is high, such as South Korea. PMID:27334929

    Objective-To review all liver transplants performed at the American University of Beirut Medical Center from 1998 to present. Materials and Methods-From 1998 to present, 21 liver transplants (15 into adults and 6 into children) were performed at the American University of Beirut Medical Center. Of the 21 transplants, 5 were living related liver transplants. Results-Patient survival was 76% at 1, 5, and 10 years. Five recipients died at a median of 9 (range, 1-56) days after transplant. Causes of death included 1 case of severe cellular rejection, 1 case of portal and hepatic artery thrombosis, 1 case of intraoperative cardiac arrest, and 2 cases of primary nonfunction. Two biliary complications and 2 major vascular complications also occurred. All 16 survivors are well, with normal findings on liver function tests at a median follow-up time of 93 (range, 10-185) months after transplant. Conclusions-Although our numbers are small, the 10-year survival rate is comparable to reported rates for other series around the world. Deceased organ donations must be encouraged so that we can perform more transplants. As a source of organs, living related liver transplant is important; however, it cannot replace deceased donation.

    To ensure donor safety in living donor liver transplantation (LDLT), the left and caudate lobe (LL) is the preferred graft choice. However, patient prognosis may still be poor even if graft volume (GV) selection criteria are met. Our aim was to evaluate the effects of right lobe (RL) donation when the LL graft selection criteria are met. Consecutive donors (n = 135) with preoperative LL graft volumetric GV/standard liver volume (SLV) of ≥35% and RL remnant of ≥35% were retrospectively studied. Patients were divided into 2 groups: LL graft and RL graft. Recipient's body surface area (BSA), Model for End-Stage Liver Disease (MELD) score, and the donor's age were higher in the RL group. The donor's BSA and preoperative volumetric GV/SLV of the LL graft were smaller in the RL group. The predicted score (calculated using data for graft size, donor age, MELD score, and the presence of portosystemic shunt, which correlated well with graft function and with 6-month graft survival) of the RL group, was significantly lower if the LL graft were used, but using the actual RL graft improved the score equal to that of the LL group. Six-month and 12-month graft survival rates did not differ between the 2 groups. In patients with a poor prognosis, a larger RL graft improved the predicted score and survival was equal to that of patients who received LL grafts. In conclusion, graft selection by GV, donor age, and recipient MELD score improves outcomes in LDLT. Liver Transplantation 22 914-922 2016 AASLD. PMID:26953726

    Excessive alcohol use is a common health care problem worldwide and is associated with significant morbidity and mortality. Alcoholic liver disease represents the second most frequent indication for liver transplantation in North America and Europe. The pretransplant evaluation of patients with alcoholic liver disease should aim at identifying those at high risk for posttransplant relapse of alcohol use disorder, as return to excessive drinking can be deleterious to graft and patient survival. Carefully selected patients with alcoholic liver disease, including those with severe alcoholic hepatitis, will have similar short-term and long-term outcomes when compared with other indications for liver transplantation.

    Hepatic venous outflow obstruction (HVOO) is a critical complication after living donor liver transplantation (LDLT). This study aimed to evaluate the incidence of HVOO and the risk factors for HVOO in adults. From 2005 to 2015, 430 adult LDLT patients (right lobe [RL] graft, 270 patients; left lobe [LL] graft, 160 patients) were enrolled and divided into no HVOO (n = 413) and HVOO (n = 17) groups. Patient demographics and surgical data were compared, and risk factors for HVOO were analyzed. Furthermore, the longterm outcomes of percutaneous interventions as treatment for HVOO were assessed. HVOO occurred in 17 (4.0%) patients. The incidence of HVOO in patients receiving a LL graft was significantly higher than in those receiving a RL graft (8.1% versus 1.5%; P = 0.001). The body weight and caliber of hepatic vein anastomosis in the HVOO group were significantly lower compared with the no HVOO group (P = 0.02 and P = 0.008, respectively). Multivariate analysis revealed that only LL graft was an independent risk factor for HVOO (OR, 4.782; 95% CI, 1.387-16.488; P = 0.01). Among 17 patients with HVOO, 7 patients were treated with single balloon angioplasty, and 9 patients who developed recurrence were treated with repeated interventions. Overall, 6 patients underwent stent placement: 1 at the initial procedure, 3 at the second procedure for early recurrence, and 2 following repeated balloon angioplasty (≥3 interventions). These 6 patients experienced no recurrence. Overall graft survival was not significantly different between the HVOO and no HVOO groups (P = 0.99). In conclusion, the use of a LL graft was associated with HVOO, and percutaneous interventions were effective for treating adult HVOO after LDLT. Liver Transplantation 22 785-795 2016 AASLD.

    Nonadherence to immunosuppressants may play a role in late rejection in liver transplant recipients. In children, emerging data suggest that adherence can be measured by computing the standard deviation (SD) of consecutive blood levels of tacrolimus, resulting in a number that reflects the degree of variability between individual measures (the Medication Level Variability Index, MLVI). A higher MLVI value means erratic immunosuppression, likely due to less adherence. Data on this method in adults are limited. We obtained data from the medical charts of 150 randomly selected adult recipients. The MLVI was significantly higher in patients who had biopsy-confirmed rejection (mean MLVI=3.8, SD=3.2) as compared with the rest of the cohort (mean MLVI=2.3, SD=1.5; p<0.01), and it was significantly higher in patients who had a rejection as compared with patients who had a biopsy that was not read as a rejection (mean MLVI=2.6, SD=1.6; p<0.01). The MLVI was both associated with rejection and predicted its occurrence. A threshold MLVI of 2.0 resulted in 77% sensitivity and 60% specificity in predicting rejection; a threshold of 1.8 resulted in a sensitivity of 92% and specificity of 48%. The Area Under the Curve (AUC) in a Receiver Operating Characteristic (ROC) curve analysis was 0.71 (95% CI: 0.61–0.81). The MLVI is associated with and can predict rejection, possibly related to nonadherence, in adult liver transplant recipients. PMID:24931127

  14. Infections After Orthotopic Liver Transplantation

    2014-01-01

    Opportunistic infections are a leading cause of morbidity and mortality after orthotopic liver transplantation. Systemic immunosuppression renders the liver recipient susceptible to de novo infection with bacteria, viruses and fungi post-transplantation as well to reactivation of pre-existing, latent disease. Pathogens are also transmissible via the donor organ. The time from transplantation and degree of immunosuppression may guide the differential diagnosis of potential infectious agents. However, typical systemic signs and symptoms of infection are often absent or blunted after transplant and a high index of suspicion is needed. Invasive procedures are often required to procure tissue for culture and guide antimicrobial therapy. Antimicrobial prophylaxis reduces the incidence of opportunistic infections and is routinely employed in the care of patients after liver transplant. In this review, we survey common bacterial, fungal, and viral infections after orthotopic liver transplantation and highlight recent developments in their diagnosis and management. PMID:25755581

    The postoperative diagnostic imaging examinations of 44 children who underwent 59 orthotopic liver transplantations were reviewed. The imaging modalities used for the evaluation of suspected complications include plain roentgenography, ultrasonography (US), computed tomography (CT), nuclear scintigraphy, arteriography, percutaneous and operative cholangiography, and endoscopic retrograde cholangiopancreatography. The main postoperative complications included ischemia, thrombosis (hepatic artery and portal vein), infarction, obstruction or leakage of the biliary anastomosis, hepatic and perihepatic infection, and allograft rejection. US, the most frequently used abdominal imaging modality, was best suited for detection of biliary duct dilatation, fluid collections in or around the transplanted liver, and hepatic arterial, inferior vena caval, and portal vein thrombosis. CT was especially helpful in corroborating findings of infection and in locating abscesses. Technetium 99m sulfur colloid (early- and late-phase imaging) provided a sensitive, although nonspecific, means of assessing allograft vascularization and morphology. Angiography showed vascularity most clearly, and cholangiography was the most useful In the assessment of bile duct patency. A diagnostic imaging algorithm is proposed for evaluation of suspected complications. PMID:3901104

    Nearly 2000 liver transplants have been performed over the past 12 years at Mount Sinai, with a recent exponential growth in living donor surgeries. Living-donor liver transplantation has emerged as an important option for our patients with end-stage liver disease. We are only beginning to recognize fully the advantages that 'scheduled' liver transplantation can offer. In this era of severe cadaver organ shortages, living donation offers patients the option of liver replacement in a timely fashion, before life-threatening complications of hepatic failure and/or carcinoma progression prohibit transplantation. The next era of transplantation at Mount Sinai will bring significant increases in the number of transplants performed with living donors, with projections of over 50% of the total transplants each year expected to involve living donations. We are committed to offering this option while recognizing that donor safety remains paramount and cannot be overemphasized. Proper donor and recipient selection, as well as surgical experience are imperative to success with this technically demanding procedure. Recurrent disease after transplantation, particularly with hepatitis C, remains a challenge clinically. Further investigations into the pathogenesis of the rapid progression of recurrent hepatitis C need to be addressed. Living donor transplantation could be an important option for these patients and would allow timely transplantation and the potential for improved survival in patients with hepatocellular carcinoma.

    Hepatocellular carcinoma (HCC) is the commonest primary malignancy of the liver. It usually occurs in the setting of chronic liver disease and has a poor prognosis if untreated. Orthotopic liver transplantation (OLT) is a suitable therapeutic option for early, unresectable HCC particularly in the setting of chronic liver disease. Following on from disappointing initial results, the seminal study by Mazzaferro et al in 1996 established OLT as a viable treatment for HCC. In this study, the “Milan criteria” were applied achieving a 4-year survival rate similar to OLT for benign disease. Since then various groups have attempted to expand these criteria whilst maintaining long term survival rates. The technique of living donor liver transplantation has evolved over the past decade, particularly in Asia, and published outcome data is comparable to that of OLT. This article will review the evidence, indications, and the future direction of liver transplantation for liver cancer. PMID:19938188

    Neurologic complications are relatively common after solid organ transplantation and affect 15%-30% of liver transplant recipients. Etiology is often related to immunosuppressant neurotoxicity and opportunistic infections. Most common complications include seizures and encephalopathy, and occurrence of central pontine myelinolysis is relatively specific for liver transplant recipients. Delayed allograft function may precipitate hepatic encephalopathy and neurotoxicity of calcineurin inhibitors typically manifests with tremor, headaches and encephalopathy. Reduction of neurotoxic immunosuppressants or conversion to an alternative medication usually result in clinical improvement. Standard preventive and diagnostic protocols have helped to reduce the prevalence of opportunistic central nervous system (CNS) infections, but viral and fungal CNS infections still affect 1% of liver transplant recipients, and the morbidity and mortality in the affected patients remain fairly high. Critical illness myopathy may also affect up to 7% of liver transplant recipients. Liver insufficiency is also associated with various neurologic disorders which may improve or resolve after successful liver transplantation. Accurate diagnosis and timely intervention are essential to improve outcomes, while advances in clinical management and extended post-transplant survival are increasingly shifting the focus to chronic post-transplant complications which are often encountered in a community hospital and an outpatient setting.

    Fanconi anemia is an inherited bone marrow failure syndrome, characterised by failing DNA repair. Hematopoetic stem cell transplantation, known to be curative for the bone marrow failure, does neither prevent or cure other manifestations such as the development of malignancies. We describe a 26-year-old male patient with known Fanconi anemia and Marfan syndrome who in 1994 underwent a successful bone marrow transplantation of stem cells from his HLA-identical sister. In 2006, three hepatocellular carcinoma (HCC) lesions in the liver were detected and promptly resected. The resection specimen contained 3 lesions, all showing activation of the beta-catenin pathway: a well differentiated steatotic HCC with remnants of the underlying adenoma from which it arose, an adenoma with small foci of well differentiated HCC and a cholestatic adenoma. Known risk factors for developing HCC include Fanconi anemia itself and the use of androgens (oxymetholone) for a period of 3 years preceeding transplantation. Because of the increased risk of developing additional HCC’s, liver transplantation was proposed, taking into account that immunosuppression increases the risk of other malignancies. By using part of the liver of the HLA-identical sister, already acting as bone marrow donor 13 years before, immunosuppression could be avoided. A left lobe liver transplantation was performed without immediate complications for donor and acceptor on July 2, 2007. Nine months after liver transplantation the recipient developed an anastomotic biliary stricture that had to be dilated by percutaneous transhepatic cholangiography. Two months later however, the stenosis recurred, necessitating a surgical reanastomosis (hepaticojejunostomy). Five years after liver transplantation the patient is still doing well. This case report is twofold special being the first case reporting Fanconi anemia linked to Marfan syndrome and being the first reported case of Fanconi anemia who was treated for

    Hepatocellular carcinoma can only be cured by physical removal or destruction of the tumor before it has spread. This can be accomplished by the ablation of the tumor, surgical resection of the tumor-bearing liver, or by liver transplantation. Ablation and resection can only be performed in patients who will be left with sufficient liver volume to sustain normal hepatic function. Unfortunately, the same disease that caused the HCC also limits the amount of parenchymal loss that can be tolerated by the patient. Liver transplantation is an appealing treatment option because it has the potential to cure patient of both the cancer and the predisposinig liver disease. Excellent survival rates are possible in patients with early HCC who receive a transplant, but dismal results are seen when patients with advanced tumors are transplanted.Wide criteria for transplant allow for more patients to be cured of HCC, but this comes at the expense of a greater overall recurrence rate. The acceptable recurrence rate is not a concrete number, but this is a function of donor organ availability. A 50% cure rate is viewed as an excellent outcome for many accepted cancer operations; however, in the case of transplant for HCC, this would represent a poor use of the scarce donor resource when the same liver offers a 70% 5-year survival rate to a non-HCC patient. These issues and methods retarding tumor progression while on the transplant waiting list are reviewed herein. PMID:17877492

    Chronic liver disease has a profound effect on nutritional status and undernourishment is almost universally present in patients with end-stage liver disease undergoing liver transplantation. In the last decades, due to epidemiological changes, a trend showing an increase in patients with end-stage liver disease and associated obesity has also been reported in developed countries. Nutrition abnormalities may influence the outcome after transplantation therefore, the importance to carefully assess the nutritional status in the work-up of patients candidates for liver transplantation is widely accepted. More attention has been given to malnourished patients as they represent the greater number. The subjective global nutritional assessment and anthropometric measurements are recognized in current guidelines to be adequate in identifying those patients at risk of malnutrition. Cirrhotic patients with a depletion in lean body mass and fat deposits have an increased surgical risk and malnutrition may impact on morbidity, mortality and costs in the post-transplantation setting. For this reason an adequate calorie and protein intake should always be ensured to malnourished cirrhotic patient either through the diet, or using oral nutritional supplements or by enteral or parenteral nutrition although studies supporting the efficacy of nutritional supplementation in improving the clinical outcomes after transplantation are still scarce. When liver function is restored, an amelioration in the nutritional status is expected. After liver transplantation in fact dietary intake rapidly normalizes and fat mass is progressively regained while the recovery of muscle mass can be slower. In some patients unregulated weight gain may lead to over-nutrition and may favor metabolic disorders (hypertension, hyperglycemia, hyperlipidemia). This condition, defined as ‘metabolic syndrome’, may play a negative role on the overall survival of liver transplant patients. In this report we

    Liver transplantation (LT) is an important component in the therapeutic armamentarium of managing end-stage liver disease. In North American children, biliary atresia remains the most common indication for LT compared to hepatitis C in adults, while hepatoblastoma is the most common liver tumor requiring LT, versus Hepatocellular carcinoma in adults. Rejection, lymphoproliferative disease, renal insufficiency, metabolic syndrome, recurrent disease, 'de novo' autoimmune hepatitis and malignancy require careful surveillance and prompt action in adults and children after LT. In children, specific attention to EBV viremia, growth, development, adherence and transition to the adult services is also required. Antibody mediated rejection and screening for donor specific antibodies is becoming important in managing liver graft dysfunction. Biomarkers to identify and predict tolerance are being developed. Machine perfusion and stem cells (iPS) to synthesize organs are generating interest and are a focus for research. PMID:26982346

    Previous reports have drawn attention to persistently decreased platelet counts among liver donors. We hypothesized an etiologic association between altered platelet counts and post-donation splenomegaly and sought to explore this relationship. This study analyzed de-identified CT/MR scans of 388 donors from 9 A2ALL centers read at a central computational image analysis lab. Resulting liver and spleen volumes were correlated with time-matched clinical lab values. Pre-donation liver volumes varied twofold in healthy subjects, even when normalized by body surface area (BSA) (range: 522 – 1887cc/m2, N=346). At 3 months post-donation liver volumes were, on average, 79% of pre-donation volumes (IQR: 73-86%, N=165) and approached 88% at 1 year (IQR: 80-93%, N=75). The mean spleen volume pre-donation was 245 cc (N=346). Spleen volumes greater than 100% of pre-donation volume occurred in 92% of donors at 3 months (N=165) and 88% at 1 year post-donation (N=75). We sought to develop a standard spleen volume (SSV) model to predict “normal” spleen volumes in donors pre-donation and found that decreased platelet counts, younger age, higher pre-donation liver volume, higher hemoglobin and higher BSA predicted a larger spleen volume (N=344, R2=0.52). When applied to post-donation values some large volumes were under predicted by the SSV model. Models developed on the reduced sample of post-donation volumes yielded smaller under-predictions. These findings confirm previous observations of thrombocytopenia associated with splenomegaly post-donation. The results of the SSV model suggest the biology of this phenomenon is complex. This merits further long term mechanistic studies of liver donors with investigation into the role of other factors such as thrombopoietin, and exposure to viral infections to better understand the evolution of spleen volume after liver donation.

  5. Current Issues in Liver Transplantation

    PubMed Central

    2016-01-01

    The state of liver transplantation continues to evolve. This article focuses on 3 separate yet important issues within this field. First, there is a proposal to change the allocation of donor livers in the United States. The fundamental premise of this proposal is to equalize access to donor livers across the country. To accomplish this goal, the proposal is to increase the geographic area of liver allocation. As might be expected, there is a great deal of controversy surrounding the possibility of a major change in liver allocation and distribution. A second area of interest, and perhaps the most important therapeutic breakthrough in the field of hepatology, is the introduction of direct-acting antiviral agents against hepatitis C virus (HCV) infection. With cure rates up to 100%, an increasing proportion of liver transplant candidates and recipients are being cured of HCV infection with therapies that have minimal side effects. Consequently, the impact of HCV infection on patient and graft survival will likely improve substantially over the next few years. Finally, this article reviews the role of donor-specific antibodies (DSAs) in antibody-mediated rejection. Long recognized as an important factor in graft survival in renal transplantation, DSAs have recently been shown to be a strong predictor of graft and patient survival in liver transplantation. However, the importance of DSAs in liver transplantation is uncertain, in large part due to the absence of proven therapies. PMID:27231452

  6. Lipids in liver transplant recipients

    Hyperlipidemia is very common after liver transplantation and can be observed in up to 71% of patients. The etiology of lipid disorders in these patients is multifactorial, with different lipid profiles observed depending on the immunosuppressive agents administered and the presence of additional risk factors, such as obesity, diabetes mellitus and nutrition. Due to recent improvements in survival of liver transplant recipients, the prevention of cardiovascular events has become more important, especially as approximately 64% of liver transplant recipients present with an increased risk of cardiovascular events. Management of dyslipidemia and of other modifiable cardiovascular risk factors, such as hypertension, diabetes and smoking, has therefore become essential in these patients. Treatment of hyperlipidemia after liver transplantation consists of life style modification, modifying the dose or type of immunosuppressive agents and use of lipid lowering agents. At the start of administration of lipid lowering medications, it is important to monitor drug-drug interactions, especially between lipid lowering agents and immunosuppressive drugs. Furthermore, as combinations of various lipid lowering drugs can lead to severe side effects, such as myopathies and rhabdomyolysis, these combinations should therefore be avoided. To our knowledge, there are no current guidelines targeting the management of lipid metabolism disorders in liver transplant recipients. This paper therefore recommends an approach of managing lipid abnormalities occurring after liver transplantation. PMID:27022213

    Alcoholic liver disease (ALD) is a common indication for liver transplantation. It is a much debated indication for deceased donor liver transplantation due to organ shortage and potential of alcohol relapse after liver transplantation. A six-month abstinence before liver transplantation is required at most centers to decrease chances of alcohol relapse after liver transplantation. However, this rule is not relevant for patients with severe alcoholic hepatitis or severely decompensated patients who are unlikely to survive till 6 months. Long-term care of these patients after liver transplantation includes assessment of relapse, smoking, and surveillance of de novo malignancies. Current review discusses role of abstinence, factors affecting alcohol relapse, liver transplantation for alcoholic hepatitis, role of living donor liver transplantation, and long-term care of ALD patients who undergo liver transplantation.

    Liver transplantation is a life-saving therapy to correct liver failure, portal hypertension and hepatocellular carcinoma arising from hepatitis C infection. But despite the successful use of living donors and improvements in immunosuppression and antiviral therapy, organ demand continues to outstrip supply and recurrent hepatitis C with accelerated progression to cirrhosis of the graft is a frequent cause of graft loss and the need for retransplantation. Appropriate selection of candidates and timing of transplantation, coupled with better pre- and post-transplant antiviral therapy, are needed to improve outcomes.

    Living donor liver transplantation (LDLT)has been performed in more than 2000 cases around the world. This procedure is considered to have certain advantages over cadaveric liver transplantation, because detailed preoperative evaluation of the donor liver is possible and superior graft quality is available. The indication has recently been widened to include adult patients. The results of LDLT have been reported to be very good. In this article,several considerations on LDLT,including living donor selection and application to adult patients, are discussed. Between June 1990 and March 2001, 143 patients underwent LDLT at Shinshu University Hospital. During this period, 160 patients were determined to be candidates for liver transplantation in our institution, and 185 candidates were evaluated as potential donors for these patients. Thirty-eight of 185 donor candidates were excluded for reasons including liver dysfunction and withdrawal of consent. The recipients included 60 adults, 50 (83%) of whom are currently alive. Taking into account the worldwide shortage of cadaveric organ donation,the importance of LDLT will probably never diminish. This procedure should be established on the basis of profound consideration of donor safety as well as accumulated expertise of hepatobiliary surgery. PMID:11865355

    Alcohol-related liver disease is the second most frequent indication for liver transplantation (LT), yet as many as 90% to 95% of patients with alcohol-related end-stage liver disease are never formally evaluated for LT. Furthermore, despite its significance as a cause of chronic liver disease and indication for LT, it has received little attention in recent years for several reasons, including the good posttransplant short-term results, and the lack of specific "drugs" used for this disease. A writing group, endorsed by the International Liver Transplant Society, was convened to write guidelines on Liver Transplantation for Alcoholic Liver Disease to summarize current knowledge and provide answers to controversial and delicate ethical as well as clinical problems. We report here a short version of the guidelines (long version available at www.ilts.org) with the final recommendations graded for level of evidence. The writing group membership is expected to remain active for 5 years, reviewing the guideline annually, and updating the online version when appropriate. PMID:26985744

    While liver transplantation is the definitive therapy for end stage liver disease, it remains a major procedure, with many potential complications. Hospital readmissions after the initial hospitalization for liver transplantation can be associated with adverse outcomes, increased cost, and resource utilization. Our aim was to define the incidence and reasons for hospital readmission after liver transplant and the impact of readmissions on patient outcomes. We retrospectively analyzed 30- and 90-day readmission rates and indications in patients who underwent liver transplant at a large-volume transplant center over a 3-year period. Four hundred seventy-nine adult patients underwent their first liver transplant during the study period. The 30-day readmission rate was 29.6%. Recipient and donor age, etiology of liver disease, biological Model for End-Stage Liver Disease score, and cold ischemia time were similar between patients who were readmitted within 30 days and those who were not readmitted. Readmissions occurred in 25% of patients who were hospitalized prior to liver transplant compared to 30% who were admitted for liver transplant. The most common indications for readmission were infection, severe abdominal pain, and biliary complications. Early discharge from hospital (fewer than 7 days after liver transplant), was not associated with readmission; however, a prolonged hospital stay after liver transplant was associated with an increased risk of readmission (p = 0.04). In conclusion, patients who undergo liver transplant have a high rate of readmission. In our cohort, readmissions were unrelated to pre-existing recipient or donor factors, but were associated with a longer hospital stay after liver transplant. PMID:27049489

    We report our single center experience with the use of basiliximab, a chimeric monoclonal antibody directed against the alpha chain of the interleukin-2 (IL-2) receptor (CD25), in combination with a steroid- and tacrolimus-based regimen in adult to adult living-related liver transplantation (ALRLT). Sixty consecutive ALRLTs were analyzed. All patients received two 20-mg doses of basiliximab (days 0 and 4 after transplantation) followed by tacrolimus (0.15 mg/kg/day; 10–15 ng/mL target trough levels) and a dose regimen of steroids (starting with 20 mg iv, switched to po as soon as the patient was able to eat, and weaned off within 1–2 months). Follow-up ranged from 6 to 1699.4 days after transplantation (mean 517.5 days, SD ± 413.4; median 424 days). Of the recipients, 95% remained rejection-free during follow-up, with an actuarial rejection-free probability of 96.61% within 3 months. Three patients had episodes of biopsy-proven acute cellular rejection (ACR). Actuarial patient and graft survival rates at 3 years were 82.09% and 75.61%. Six patients (10%) experienced sepsis. There was no evidence of cytomegalovirus infections or side-effects related to the basiliximab. We found zero de novo malignancy, although we observed 5 patients with metastatic spread of their primary malignancy during the follow-up. Basiliximab in association with tacrolimus and steroids is effective in reducing episodes of ACR and increasing ACR-free survival after ALRLT. PMID:19707350

    In Egypt there is no doubt that chronic liver diseases are a major health concern. Hepatitis C virus (HCV) prevalence among the 15−59 years age group is estimated to be 14.7%. The high prevalence of chronic liver diseases has led to increasing numbers of Egyptian patients suffering from end stage liver disease (ESLD), necessitating liver transplantation (LT). We reviewed the evolution of LT in Egypt and the current status. A single center was chosen as an example to review the survival and mortality rates. To date, deceased donor liver transplantation (DDLT) has not been implemented in any program though Egyptian Parliament approved the law in 2010. Living donor liver transplantation (LDLT) seemed to be the only logical choice to save many patients who are in desperate need for LT. By that time, there was increase in number of centers doing LDLT (13 centers) and increase in number of LDLT cases [2,400] with improvement of the results. Donor mortality rate is 1.66 per 1,000 donors; this comprised four donors in the Egyptian series. The exact recipient survival is not accurately known however, and the one-year, three-year and five-year survival were 73.17%, 70.83% and 64.16% respectively in the International Medical Center (IMC) in a series of 145 adult to adult living donor liver transplantation (AALDLT) cases. There was no donor mortality in this series. LDLT are now routinely and successfully performed in Egypt with reasonable donor and recipient outcomes. Organ shortage remains the biggest hurdle facing the increasing need for LT. Although LDLT had reasonable outcomes, it carries considerable risks to healthy donors. For example, it lacks cadaveric back up, and is not feasible for all patients. The initial success in LDLT should drive efforts to increase the people awareness about deceased organ donation in Egypt. PMID:27115003

    Liver transplantation originated in children more than 50 years ago, and these youngest patients, while comprising the minority of liver transplant recipients nationwide, can have some of the best and most rewarding outcomes. The indications for liver transplantation in children are generally more diverse than those seen in adult patients. This diversity in underlying cause of disease brings with it increased complexity for all who care for these patients. Children, still being completely dependent on others for survival, also require a care team that is able and ready to work with parents and family in addition to the patient at the center of the process. In this review, we aim to discuss diagnoses of particular uniqueness or importance to pediatric liver transplantation. We also discuss the evaluation of a pediatric patient for liver transplant, the system for allocating them a new liver, and also touch on postoperative concerns that are unique to the pediatric population.

    Adult-to-adult living donor liver transplantation (LDLT) is a complex procedure that poses serious health risks to and provides no direct health benefit for the donor. Because of this uneven risk-benefit ratio, ensuring donor autonomy through informed consent is critical. To assess the current knowledge pertaining to informed consent for LDLT, we conducted a systematic review of the empirical literature on donors' decision-making process, comprehension about risks and outcomes, and information needs for LDLT. Of the 1423 identified articles, 24 met final review criteria, representing the perspective of approximately 2789 potential and actual donors. As donors' decisions to donate often occur before evaluation, they often make uninformed decisions. The review found that 88% to 95% of donors reported understanding information clinicians disclosed about risks and benefits. However, donors reported unmet information needs, knowledge gaps regarding risks, and unanticipated complications. Few donors reported feeling pressure to donate. Most studies were limited by cultural differences, small sample sizes, inconsistent measures, and poor methodological approaches. This systematic review suggests that informed consent for LDLT is sub-optimal as donors do not adequately appreciate disclosed information during the informed consent process, despite United Network for Organ Sharing/CMS regulations requiring formal psychological evaluation of donor candidates. Interventions are needed to improve donor-clinician communication during the LDLT informed consent process such as through the use of comprehension assessment tools and e-health educational tools that leverage adult learning theory to effectively convey LDLT outcome data.

    The most appropriate treatment for Klatskin tumor (KT) with a curative intention is multimodal therapy based on achieving resection with tumour-free margins (R0 resections) combined with other types of neoadjuvant or adjuvant treatment (the most important factor affecting KT survival is the possibility of R0 resections, achieving 5-year survival rate of 40%-50%). Thirty to forty percent of patients with KT are inoperable and present a 5-year survival rate of 0%. In irresectable non-disseminated KT patients, using liver transplantation without neoadjuvant treatment, the 5-year survival rate increase to 38%, reaching 50% survival in early stage. In selected cases, with liver transplantation and neoadjuvant treatment (chemotherapy and radiotherapy), the actuarial survival rate is 65% at 5 years and 59% at 10 years. In conclusion, correct staging, neoadjuvant treatment, living donor and priority on the liver transplant waiting list may lead to improved results. PMID:24409049

    After having experienced more than 2,000 cases of adult living donor liver transplantation (LDLT), we established the concepts of right liver graft standardization. Right liver graft standardization intends to provide hemodynamics-based and regeneration-compliant reconstruction of vascular inflow and outflow. Right liver graft standardization consists of the following components: Right hepatic vein reconstruction includes a combination of caudal-side deep incision and patch venoplasty of the graft right hepatic vein to remove the acute angle between the graft right hepatic vein and the inferior vena cava; middle hepatic vein reconstruction includes interposition of a uniform-shaped conduit with large-sized homologous or prosthetic grafts; if the inferior right hepatic vein is present, its reconstruction includes funneling and unification venoplasty for multiple short hepatic veins; if donor portal vein anomaly is present, its reconstruction includes conjoined unification venoplasty for two or more portal vein orifices. This video clip that shows the surgical technique from bench to reperfusion was a case presentation of adult LDLT using a modified right liver graft from the patient's son. Our intention behind proposing the concept of right liver graft standardization is that it can be universally applicable and may guarantee nearly the same outcomes regardless of the surgeon's experience. We believe that this reconstruction model would be primarily applied to a majority of adult LDLT cases. PMID:27621745

    Liver transplantation (LT) in Australia and New Zealand began in 1985. Over this time until December 2014, LT took place in 3700 adults and 800 children. LT is regulated with 1 unit, supported by the government, per state or region. Currently approximately 270 transplants take place per year. Organ donation rates are moderate in Australia (17 per 1 million of population) but very low in New Zealand (11 per 1 million of population). All the units share organ donors for fulminant hepatic failure cases (status 1). Recipient listing criteria and organ allocation criteria are commonly agreed to via National and Trans-Tasman agreements, which are published online. Current survival rates indicate approximately 94% 1-year survival with median survival in adults of approximately 20 years, whereas 75% of children are alive at 20 years. All units collaborate in research projects via the Australia and New Zealand Liver Transplant Registry and have published highly cited articles particularly on the prevention of hepatitis B virus recurrence. Outcomes for indigenous populations have also been analyzed. In conclusion, LT in Australia and New Zealand is well developed with transparent processes related to criteria for listing and organ allocation together with publication of outcomes.

Although the mechanisms mediating these abnormalities are incompletely defined, advances in the understanding of renal pathophysiology after liver transplantation have made it possible to develop new treatment strategies. Aggressive and early intervention to diagnose and treat renal complications associated with liver transplantation should be the goal for transplant centres. PMID:7479462

    Infectious complications are major causes of morbidity and mortality after liver transplantation, despite recent advances in the transplant field. Bacteria, fungi, viruses and parasites can cause infection before and after transplantation. Among them, bacterial infections are predominant during the first two months post-transplantation and affect patient and graft survival. They might cause surgical site infections, including deep intra-abdominal infections, bacteremia, pneumonia, catheter-related infections and urinary tract infections. The risk factors for bacterial infections differ between the periods after transplant, and between centers. Recently, the emergence of multi-drug resistant bacteria is great concern in liver transplant (LT) patients. The instructive data about effects of infections with extended-spectrum beta lactamase producing bacteria, carbapenem-resistant gram-negative bacteria, and glycopeptide-resistant gram-positive bacteria were reported on a center-by-center basis. To prevent post-transplant bacterial infections, proper strategies need to be established based upon center-specific data and evidence from well-controlled studies. This article reviewed the recent epidemiological data, risk factors for each type of infections and important clinical issues in bacterial infection after LT. PMID:24876741

    The transition from pediatric to adult care is a critical time when children with chronic illness sustain high morbidity and mortality. Transition services need to be focused on the adolescents' needs, which may differ from those perceived by healthcare providers. In this study, a survey of 31 patients with chronic liver disease and/or liver transplant who were “transferred” to adult services within the last 3 years was conducted. Patients were asked about their current health status and their perceptions of the overall transfer process. The mean age at transfer was 19.81 (18–21) years. Almost half the patients (47%) were not seen at the adult facility until 2–6 months after leaving the Children's hospital and 20% were not seen until 6–12 months. About 20% had their first contact with adult services through an emergency room visit. About 19% reported being out of medication during transition. Of the transplanted patients, 19% were being evaluated for a retransplant. The majority (82%) felt that an increased emphasis on promoting independence and “letting go” both by parents and by pediatric care providers was critical in their transition to independence and adult care services. This study provides thought-provoking insights, which are critical in designing the ideal transition program for children with chronic diseases. PMID:26682071

  6. Infections Following Orthotopic Liver Transplantation

    1991-01-01

    The epidemiology of infections associated with orthotopic liver transplantation is summarized herein, and approaches to prophylaxis are outlined. Infection is a major complication following orthotopic liver transplantation, and more than half of transplant recipients develop at least one infection. The risk of infection is highest in the first month after transplantation, and the most common pathogens are bacteria and cytomegalovirus (CMV). Bacterial infections usually occur in the first month, arise in the abdomen, and are caused by aerobes. The peak incidence of CMV infection is late in the first month and early in the second month after transplantationn. CMV syndromes include fever and neutropenia, hepatitis, pneumonitis, gut ulceration, and disseminated infection. Other significant problems are Candida intraabdominal infection, Herpes simplex mucocutaneous infection or hepatitis, adenovirus hepatitis, and Pneumocystis carinii pneumonia. Prophylaxis of infection in liver transplant recipients has not been well-studied. Several different regimens of parenteral, oral absorbable, and/or oral non-absorbable antibiotics active against bacteria and yeast have been used at various centers, but no randomized controlled trials have been conducted. Selective bowel decontamination appears to be a promising approach to the prevention of bacterial and Candida infections, while oral acyclovir may be a relatively convenient and effective agent for CMV prophylaxis.

    Nonalcoholic fatty liver disease (NAFLD) is prevalent in the general population and a growing indication for liver transplant. Longer wait times and challenges with pretransplant survivorship are expected, underscoring the need for improved management of attendant comorbidities. Recognition with potential modification of obesity, sarcopenia, chronic kidney disease, and cardiovascular disease in patients with NAFLD may have important implications in the pretransplant and posttransplant periods. Although patients with NAFLD have generally favorable postoperative outcomes, they are at risk for developing recurrent disease in their allograft, driving the need for pharmacotherapies and dietary innovations appropriate for use in the posttransplant period.

    In 1958 Francis Moore described the orthotopic liver transplantation technique in dogs. In 1963, Starzl et al. performed the first liver transplantation. In the first five liver transplantations no patient survived more than 23 days. In 1967, stimulated by Calne who used antilymphocytic serum, Starzl began a successful series of liver transplantation. Until 1977, 200 liver transplantations were performed in the world. In that period, technical problems were overcome. Roy Calne, in 1979, used the first time cyclosporine in two patients who had undergone liver transplantation. In 1989, Starzl et al. reported a series of 1,179 consecutives patients who underwent liver transplantation and reported a survival rate between one and five years of 73% and 64%, respectively. Finally, in 1990, Starzl et al. reported successful use of tacrolimus in patents undergoing liver transplantation and who had rejection despite receiving conventional immunosuppressive treatment. Liver Transplantation Program was initiated at Hospital Israelita Albert Einstein in 1990 and so far over 1,400 transplants have been done. In 2013, 102 deceased donors liver transplantations were performed. The main indications for transplantation were hepatocellular carcinoma (38%), hepatitis C virus (33.3%) and alcohol liver cirrhosis (19.6%). Of these, 36% of patients who underwent transplantation showed biological MELD score > 30. Patient and graft survival in the first year was, 82.4% and 74.8%, respectively. A major challenge in liver transplantation field is the insufficient number of donors compared with the growing demand of transplant candidates. Thus, we emphasize that appropriated donor/receptor selection, allocation and organ preservation topics should contribute to improve the number and outcomes in liver transplantation. PMID:25993082

    In 1958 Francis Moore described the orthotopic liver transplantation technique in dogs. In 1963, Starzl et al. performed the first liver transplantation. In the first five liver transplantations no patient survived more than 23 days. In 1967, stimulated by Calne who used antilymphocytic serum, Starzl began a successful series of liver transplantation. Until 1977, 200 liver transplantations were performed in the world. In that period, technical problems were overcome. Roy Calne, in 1979, used the first time cyclosporine in two patients who had undergone liver transplantation. In 1989, Starzl et al. reported a series of 1,179 consecutives patients who underwent liver transplantation and reported a survival rate between one and five years of 73% and 64%, respectively. Finally, in 1990, Starzl et al. reported successful use of tacrolimus in patents undergoing liver transplantation and who had rejection despite receiving conventional immunosuppressive treatment. Liver Transplantation Program was initiated at Hospital Israelita Albert Einstein in 1990 and so far over 1,400 transplants have been done. In 2013, 102 deceased donors liver transplantations were performed.

    Background Ischaemic preconditioning (IPC) of the right liver graft in the donor has not been studied in adult-to-adult living related liver transplantation (LRLT). Objective To assess the IPC effect of the graft on ischaemia reperfusion injury in the recipient and compare recipient and donor outcomes with and without preconditioned grafts. Patients and methods Alternate patients were transplanted with right lobe grafts that were (n =22; Group Precond) or were not (n =22; Group Control) subjected to IPC in the living donor. Liver ischaemia–reperfusion injury, liver/kidney function, morbidity/mortality rates and outcomes were compared. Univariate and multivariate analyses were performed to identify factors predictive of the aspartate aminotransferase (AST) peak and minimum prothrombin time. Results Both groups had similar length of hospital stay, morbidity/mortality, primary non-function and acute rejection rates. Post-operative AST (P =0.8) and alanine aminotransferase (ALT) peaks (P =0.6) were similar in both groups (307 ± 189 and 437 ± 302 vs. 290 ± 146 and 496 ± 343, respectively). In univariate analysis, only pre-operative AST and warm ischemia time (WIT) were significantly associated with post-operative AST peak (in recipients). In multivariate analysis, the graft/recipient weight ratio (P =0.003) and pre-operative bilirubin concentration (P =0.004) were significantly predictive of minimum prothrombin time post-transplantation. Conclusions Graft IPC in the living related donor is not associated with any benefit for the recipient or the donor and its clinical value remains uncertain. PMID:20815852

    In 1953, the pioneer of human orthotopic liver transplantation (LT), Thomas E Starzl, was the first to attempt an orthotopic liver transplant into a 3 years old patient suffering from biliary atresia. Thus, the first LT in humans was attempted in a disease, which, up until today, remains the main indication for pediatric LT (pLT). During the last sixty years, refinements in diagnostics and surgical technique, the introduction of new immunosuppressive medications and improvements in perioperative pediatric care have established LT as routine procedure for childhood acute and chronic liver failure as well as inherited liver diseases. In contrast to adult recipients, pLT differs greatly in indications for LT, allocation practice, surgical technique, immunosuppression and post-operative life-long aftercare. Many aspects are focus of ongoing preclinical and clinical research. The present review gives an overview of current developments and the clinical outcome of pLT, with a focus on alternatives to full-size deceased-donor organ transplantation. PMID:26085910

    Patient: Male, 66 Final Diagnosis: Fibrosing cholestatic hepatitis Symptoms: Prolonged jaundice and intractable ascites Medication: Steroid pulse therapy and direct-acting antivirals Clinical Procedure: Liver transplantation Specialty: Transplantology Objective: Challenging differential diagnosis Background: Hepatitis C recurrence is a serious matter after liver transplantation (LT). Approximately 10% of hepatitis C virus (HCV) positive recipients develop fibrosing cholestatic hepatitis (FCH). FCH rapidly results in graft loss. Currently, direct-acting antivirals (DAAs) are effective and safe for hepatitis C, even after LT. However, only a few cases of successfully treated FCH after LT have been reported. We present FCH in a complicated case with sepsis and portal flow obstruction after LT. Case Report: A 66-year-old man underwent cadaveric LT. Liver function disorders were observed from post-operative day (POD) 22. Sepsis repeated on POD 38, 74, and 101. Steroid pulse therapy was given from POD 40 to 54. The infectious focus was surgically removed on POD 89. Interventional radiology for portal venous obstruction was completed on POD 96. To make a real-time diagnosis and to investigate the graft condition, repeat liver needle biopsies (LNBs) were taken. Although there was a combined impact of sepsis, portal flow decrease, and recurrent hepatitis C on graft failure, it was interesting that recurrent hepatitis C was consistently detectable from the first LNB. HCV-ribonucleic acid increased on POD 68. Liver function disorders peaked on POD 71 and 72. Jaundice peaked on POD 82. DAA induction was regrettably delayed because of a reluctance to introduce DAAs under conditions of graft dysfunction. DAAs were administered after hospital discharge. Conclusions: A real-time and precise diagnosis based on histopathological examination and viral measurement is important for FCH treatment. Well-considered therapy with DAAs should be aggressively introduced for potentially fatal

    Biliary complications are regarded as the Achilles' heel of liver transplantation, especially for living donor liver transplantation (LDLT) due to smaller, multiple ducts and difficult ductal anatomy. Overall biliary complications reported in most series are between 10% and 30%. This study describes our modified technique of biliary anastomosis and its effects on incidence of biliary complications. This was a single-center retrospective study of 148 adult LDLT recipients between December 2011 and June 2014. Group 1 (n = 40) consisted of the first 40 patients for whom the standard technique of biliary anastomosis (minimal hilar dissection during donor duct division, high hilar division of the recipient bile duct, and preservation of the recipient duct periductal tissue) was used. Group 2 (n = 108) consisted of 108 patients for whom biliary anastomosis was done with the addition of corner-sparing sutures and mucosal eversion of the recipient duct to the standard technique. Primary outcome measures included biliary complications (biliary leaks and strictures). Biliary complications occurred in 7/40 patients in group 1 (17.5%) and in 4/108 patients in group 2 (3.7%). The technical factors mentioned above are aimed at preserving the blood supply of the donor and recipient ducts and hold the key for minimizing biliary complications in adult-to-adult LDLT.

    2014-01-01

    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. These loci may provide a clue as to the immune-based pathogenesis of AILD. Moreover, many significant risk loci for PBC and PSC are also risk loci for other autoimmune disorders, such type I diabetes, multiple sclerosis and rheumatoid arthritis, suggesting a shared genetic basis and possibly similar molecular pathways for diverse autoimmune conditions. There is no curative treatment for all three disorders, and a significant number of patients eventually progress to end-stage liver disease requiring liver transplantation (LT). LT in this context has a favourable overall outcome with current patient and graft survival exceeding 80% at 5years. Indications are as for other chronic liver disease although recent data suggest that while lethargy improves after transplantation, the effect is modest and variable so lethargy alone is not an indication. In contrast, pruritus rapidly responds. Cholangiocarcinoma, except under rigorous selection criteria, excludes LT because of the high risk of recurrence. All three conditions may recur after transplantation and are associated with a greater risk of both acute cellular and chronic ductopenic rejection. It is possible that a crosstalk between alloimmune and autoimmune response perpetuate each other. An immunological response toward self- or allo-antigens is well recognised after LT in patients transplanted for non-autoimmune indications and sometimes termed "de novo autoimmune hepatitis". Whether this is part of the spectrum of rejection or an autoimmune

    In this article the authors discuss the advantages of Living Related Liver Transplantation (LRLT), criteria for the selection of donors and the standard operation technique. Among a total of 241 liver transplantation (LTx), 42 LRLT were performed at the University of Hamburg between October 1, 1991 and December 19, 1994. The body weight of recipients for LRLT ranged from 4,6 to 39 kg, with 64,2% having less than 10 kg. The volume of the donor left lateral liver lobe ranged from 100 cc to 350 cc. The average one year survival rate among electively operated patients-status 3-4 (UNOS 1995 classification) was 86.7%, two year survival rate 83.3%. The main advantages of LRLT are consired the following: 1. Absence of mortality on the waiting list, 2. Optimal timing of the transplantation (elective procedure, patient in a good condition), 3. Excellent organ (no primary non function), 4. A possible immunologic advantage, 5. Relief of the waiting list for cadaveric organs, 6. Psychological benefit for the family, 7. Cost effectiveness. Potential candidates for living donation with more than one cardiovascular risk factors were excluded. Social and psychological reasons leading to rejection of candidates were as follows: unstable family structure, expected professional or financial difficulties after living donation or withdrawal from consent. LRLT gives parents of a child with TLD a chance to avoid the risk of death on the waiting list or primary non function of the graft. LRLT has therefore established an important place in pediatric liver transplantation. PMID:8768973

    Growing experience with the liver splitting technique and favorable results equivalent to those of whole liver transplant have led to wider application of split liver transplantation (SLT) for adult and pediatric recipients in the last decade. Conversely, SLT for two adult recipients remains a challenging surgical procedure and outcomes have yet to improve. Differences in organ shortages together with religious and ethical issues related to cadaveric organ donation have had an impact on the worldwide distribution of SLT. Despite technical refinements and a better understanding of the complex liver anatomy, SLT remains a technically and logistically demanding surgical procedure. This article reviews the surgical and clinical advances in this field of liver transplantation focusing on the role of SLT and the issues that may lead a further expansion of this complex surgical procedure.

    Orthotopic liver transplantation (OLT) is the standard of care for patients with decompensated cirrhosis and for patients with hepatocellular carcinoma. More than 6000 liver transplants are performed annually in the United States. High patient and graft survival rates have been achieved in great part due to the availability of potent immunosuppressive agents. Systemic immunosuppression has rendered the liver recipient susceptible to de novo infections as well as reactivation of preexisting latent infections. Infections occurring during the first month post-OLT are usually nosocomial, donor-derived, or the result of a perioperative complication. The development of opportunistic infections (OIs) such as Aspergillus and the reactivation of latent infections such as Mycobacterium tuberculosis are more frequent 1 to 6 months posttransplant, when the net state of immunosuppression is the highest. Immunosuppressive therapy is tapered 6 to 12 months post-OLT; therefore, infections occurring during that time period and afterward generally resemble those of the general population. Screening strategies applied to determine the risk of an infection after transplantation and the use of prophylactic antimicrobial therapy have reduced the incidence of OIs after OLT. This article will review the various causes of infection post-OLT and the therapies used to manage complications. PMID:27134589

    Background & Aims Adult-to-adult living donors and recipients were studied to characterize patterns of liver growth and identify associated factors in a multicenter study. Methods 350 donors and 353 recipients in A2ALL (Adult to Adult Living Donor Liver Transplantation Cohort Study) transplanted between March 2003 and February 2010 were included. Potential predictors of 3-month liver volume included total and standard liver volumes (TLV, SLV), the model for end-stage liver disease (MELD) score (in recipients), remnant and graft size, remnant to donor and graft to recipient weight ratio (RDWR, GRWR), remnant/TLV, and graft/SLV. Results Among donors, 3-month absolute growth was 676±251g (mean± SD) and percent reconstitution was 80%±13%. Among recipients, GRWR was 1.3%±0.4% (8<0.8%). Graft weight was 60%±13% of SLV. Three-month absolute growth was 549±267g and percent reconstitution was 93%±18%. Predictors of greater 3-month liver volume included larger patient size (donors, recipients), larger graft volume (recipients), and larger TLV (donors). Donors with the smallest remnant/TLV ratios had larger than expected growth, but also had higher postoperative bilirubin and international normalized ratio at 7 and 30 days. In a combined donor-recipient analysis, donors had smaller 3-month liver volumes than recipients adjusted for patient size, remnant or graft volume, and TLV or SLV (p=0.004). Recipient graft failure in the first 90 days was predicted by poor graft function at day 7 (HR=4.50, p=0.001), but not by GRWR or graft fraction (p>0.90 for each). Conclusions Both donors and recipients had rapid yet incomplete restoration of tissue mass in the first 3 months, confirming previous reports. Recipients achieved a greater percentage of expected total volume. Patient size and recipient graft volume significantly influenced 3 month volumes. Importantly, donor liver volume is a critical predictor of the rate of regeneration, and donor remnant fraction impacts post

    In an era of great achievements in liver transplantation, hepatitis C viral infection (HCV) remains an unsolved problem. As a leading indication for liver transplantation in Western countries, HCV poses a significant burden both before and after transplantation. Post-transplant disease recurrence occurs in nearly all patients with detectable pretransplant viremia, compromising the lifesaving significance of transplantation. Many factors involving the donor, recipient and virus have been evaluated throughout the literature, although few have been fully elucidated and implemented in actual clinical practice. Antiviral therapy has been recognized as a cornerstone of HCV infection control; however, experience and success are diminished following transplantation in a challenging cohort of patients with liver cirrhosis. Current therapeutic protocols surpass those used previously, both in sustained viral response and side-effect profile. In this article we review the most relevant and contemporary scientific evidence regarding hepatitis C infection and liver transplantation, with special attention dedicated to novel, more efficient and safer antiviral regimens.

    Liver transplantation (LT) has become the standard of care for patients with end stage liver disease. The allocation of organs, which prioritizes the sickest patients, has made the management of liver transplant candidates more complex both as regards their comorbidities and their higher risk of perioperative complications. Patients undergoing LT frequently display considerable physiological changes during the procedures as a result of both the disease process and the surgery. Transoesophageal echocardiography (TEE), which visualizes dynamic cardiac function and overall contractility, has become essential for perioperative LT management and can optimize the anaesthetic management of these highly complex patients. Moreover, TEE can provide useful information on volume status and the adequacy of therapeutic interventions and can diagnose early intraoperative complications, such as the embolization of large vessels or development of pulmonary hypertension. In this review, directed at clinicians who manage TEE during LT, we show why the procedure merits a place in challenging anaesthetic environment and how it can provide essential information in the perioperative management of compromised patients undergoing this very complex surgical procedure.

    The portal hyperperfusion, or small-for-size syndrome (SFSS), is a widely recognized clinical complication that may occur after segmental liver transplantation. Several surgical strategies have been proposed to reduce portal blood inflow and portal pressure after partial liver transplantation. In particular, splenic artery ligation and splenectomy have been used without a firm hemodynamic basis for these procedures. Our group recently demonstrated that, in patients with cirrhosis and portal hypertension, the occlusion of the splenic artery causes a significant reduction in the portal pressure gradient, which is directly related to the spleen volume and indirectly related to the liver volume. This concept is at the center of our strategy for performing early splenic artery embolization (SAE) for the treatment of SFSS after living-related liver transplantation (LRLT). Six patients developed small-for-size syndrome, defined as: onset within the first week after LRLT of progressive hyperbilirubinemia without mechanical cause; marked cholestasis; centrilobular sinusoidal dilatation and hepatocyte atrophy at liver biopsy; and refractory ascites in the absence of vascular complications. All six patients who underwent SAE rapidly improved their clinical condition, with an evident decrease in the value of bilirubin in the serum, in the production of ascites, and improvement in condition of pancytopenia. Coagulopathy expressed by the international normalized ratio value (INR) was not a reliable early marker of SFSS in this series; in fact a slight improvement in the result of this test was already present immediately after LRLT and before SAE. Because splenic flow clearly contributes to portal hyperperfusion, an early SAE can relieve the partial graft from the deleterious effect of this portal overflow. PMID:17988271

    Adult living donor liver transplantation (LDLT) is increasingly used for the treatment of end-stage liver disease. The three most commonly harvested grafts for LDLT are left lateral segment, left lobe, and right lobe grafts. The left lateral segment graft, which includes Couinaud’s segments II and III, is usually used for pediatric recipients or small size recipients. Most of the adult recipients need either a left or a right lobe graft. Whether a left or right lobe graft should be harvested from the donors depends on estimated graft and donor remnant liver volume, as well as biliary and vascular anatomy. Detailed preoperative assessment of the potential donor liver volumetrics, biliary and vascular anatomy, and liver parenchyma is vital to minimize risks to the donors and maximize benefits to the recipients. Computed tomography (CT) and magnetic resonance imaging (MRI) are currently the imaging modalities of choice in the preoperative evaluation of potential donors. This review provides an overview of key surgical considerations in LDLT that the radiologists must be aware of, and imaging findings on CT and MRI that the radiologists must convey to the surgeons when evaluating potential donors for LDLT.

    Acute liver failure is a critical medical condition defined as rapid development of hepatic dysfunction associated with encephalopathy. The prognosis in these patients is highly variable and depends on the etiology, interval between jaundice and encephalopathy, age, and the degree of coagulopathy. Determining the prognosis for this population is vital. Unfortunately, prognostic models with both high sensitivity and specificity for prediction of death have not been developed. Liver transplantation has dramatically improved survival in patients with acute liver failure. Still, 25% to 45% of patients will survive with medical treatment. The identification of patients who will eventually require liver transplantation should be carefully addressed through the combination of current prognostic models and continuous medical assessment. The concerns of inaccurate selection for transplantation are significant, exposing the recipient to a complex surgery and lifelong immunosuppression. In this challenging scenario, where organ shortage remains one of the main problems, alternatives to conventional orthotopic liver transplantation, such as living-donor liver transplantation, auxiliary liver transplant, and ABO-incompatible grafts, should be explored. Although overall outcomes after liver transplantation for acute liver failure are improving, they are not yet comparable to elective transplantation. PMID:26819519

    Transplantation for the treatment of alcoholic cirrhosis is more controversially discussed than it is for any other indication. The crucial aspect in this setting is abstinence before and after liver transplantation. We established pre-transplant selection criteria for potential transplant candidates. Provided that the underlying disease can be treated, there is no reason to withhold liver transplantation in a patient suffering from alcoholic cirrhosis. Evaluation of the patient by a multidisciplinary team, including an addiction specialist, is considered to be the gold standard. However, several centers demand a specified period of abstinence - usually 6 mo- irrespective of the specialist's assessment. The 6-mo rule is viewed critically because liver transplantation was found to clearly benefit selected patients with acute alcoholic hepatitis; the benefit was similar to that achieved for other acute indications. However, the discussion may well be an academic one because the waiting time for liver transplantation exceeds six months at the majority of centers. The actual challenge in liver transplantation for alcoholic cirrhosis may well be the need for lifelong post-transplant follow-up rather than the patient's pre-transplant evaluation. A small number of recipients experience a relapse of alcoholism; these patients are at risk for organ damage and graft-related death. Post-transplant surveillance protocols should demonstrate alcohol relapse at an early stage, thus permitting the initiation of adequate treatment. Patients with alcoholic cirrhosis are at high risk of developing head and neck, esophageal, or lung cancer. The higher risk of malignancies should be considered in the routine assessment of patients suffering from alcoholic cirrhosis. Tumor surveillance protocols for liver transplant recipients, currently being developed, should become a part of standard care; these will improve survival by permitting diagnosis at an early stage. In conclusion, the key

Provided that the underlying disease can be treated, there is no reason to withhold liver transplantation in a patient suffering from alcoholic cirrhosis. Evaluation of the patient by a multidisciplinary team, including an addiction specialist, is considered to be the gold standard. However, several centers demand a specified period of abstinence - usually 6 mo- irrespective of the specialist’s assessment. The 6-mo rule is viewed critically because liver transplantation was found to clearly benefit selected patients with acute alcoholic hepatitis; the benefit was similar to that achieved for other acute indications. However, the discussion may well be an academic one because the waiting time for liver transplantation exceeds six months at the majority of centers. The actual challenge in liver transplantation for alcoholic cirrhosis may well be the need for lifelong post-transplant follow-up rather than the patient’s pre-transplant evaluation. A small number of recipients experience a relapse of alcoholism; these patients are at risk for organ damage and graft-related death. Post-transplant surveillance protocols should demonstrate alcohol relapse at an early stage, thus permitting the initiation of adequate treatment. Patients with alcoholic cirrhosis are at high risk of developing head and neck, esophageal, or lung cancer. The higher risk of malignancies should be considered in the routine assessment of patients suffering from alcoholic cirrhosis. Tumor surveillance protocols for liver transplant recipients, currently being developed, should become a part of standard care; these will improve survival by permitting diagnosis at an early stage.

    The shortage of deceased donor liver grafts led to the use of living donor liver transplant (LDLT). Patients who undergo LDLT have a higher risk of complications than those who undergo deceased donor liver transplantation (LT). Interventional radiology has acquired a key role in every LT program by treating the majority of vascular and non-vascular post-transplant complications, improving graft and patient survival and avoiding, in the majority of cases, surgical revision and/or re-transplant. The aim of this paper is to review indications, diagnostic modalities, technical considerations, achievements and potential complications of interventional radiology procedures after LDLT.

    Liver transplantation, either a partial liver from a living or deceased donor or a whole liver from a deceased donor, is the only curative therapy for severe end-stage liver disease. Only one-third of those on the liver transplant waiting list will be transplanted, and the demand for livers is projected to increase 23% in the next 20 years. Consequently, organ availability is an absolute constraint on the number of liver transplants that can be performed. Regenerative therapies aim to enhance liver tissue repair and regeneration by any means available (cell repopulation, tissue engineering, biomaterials, proteins, small molecules, and genes). Recent experimental work suggests that liver repopulation and engineered liver tissue are best suited to the task if an unlimited availability of functional induced pluripotent stem (iPS)-derived liver cells can be achieved. The derivation of iPS cells by reprogramming cell fate has opened up new lines of investigation, for instance, the generation of iPS-derived xenogeneic organs or the possibility of simply inducing the liver to reprogram its own hepatocyte function after injury. We reviewed current knowledge about liver repopulation, generation of engineered livers and reprogramming of liver function. We also discussed the numerous barriers that have to be overcome for clinical implementation. PMID:26699680

    Background Biliary complications following liver transplantation result in major morbidity. We undertook a 10-year audit of the incidence, management and outcomes of post-transplant biliary complications at the New Zealand Liver Transplant Unit. Methods Prospectively collected data on 348 consecutive liver transplants performed between February 1998 and October 2008 were reviewed. The minimum follow-up was 6 months. Results A total of 309 adult and 39 paediatric transplants were performed over the study period. Of these, 296 (85%) were whole liver grafts and 52 (15%) were partial liver grafts (24 split-liver, eight reduced-size and 20 live-donor grafts). There were 80 biliary complications, which included 63 (18%) strictures and 17 (5%) bile leaks. Partial graft, a paediatric recipient and a Roux-en-Y biliary anastomosis were independent predictors of biliary strictures. Twenty-five (40%) strictures were successfully managed non-operatively and 38 (60%) required surgery (31 biliary reconstructions, three segmental resections and four retransplants). Seven (41%) bile leaks required surgical revision and 10 (59%) were managed non-operatively. There was no mortality related directly to biliary complications. Conclusions Biliary complications affected one in five transplant recipients. Paediatric status, partial graft and Roux-en-Y anastomosis were independently associated with the occurrence of biliary strictures. Over half of the affected patients required surgical revision, but no mortality resulted from biliary complications. PMID:21609371

    Our organizational model allows an annual 1,000 liver transplants. Pediatric liver transplantation constitutes 5% of such activity and provides, in children with severe, progressive and irreversible liver disease, a 1 year-survival of 90% and more than 80% after 15 years of follow-up. The main indication is biliary atresia followed by metabolic liver disease and acute liver failure. Around half of the procedures are performed in children under two years and 25-30% in the first year of life. The waiting list remains at around 35 patients, with an average of 100 patients enrolled annually and 60 of them finally transplanted after an average of 136.3 days on the waiting list. The prioritization of the candidates uses the PELD as an objective tool for decision-making. However, the progressive aging of donors, with a profile increasingly different from the requirements of the pediatric patients included in the waiting list, requires strategies such as living donor liver transplantation and the split liver transplantation, to increase the probability of transplant while reducing both time and mortality on the waiting list at the same time. Pediatric intestinal transplantation registers a low indication but involves strict requirements that outline a very uncommon donor in our country which, together with the absence of alternatives that outweigh the impact of these difficulties, penalizes the chances of transplant for these patients.

    Organ grafts developed in the xenogeneic pig scaffold are expected to resolve most issues of donor safety and ethical concerns about living-donor liver transplantation in Japan. We have been working on so-called "Yamaton" projects to develop transplantable organs using genetically engineered pigs. Our goal is to produce chimeric livers with human parenchyma in such pigs. The Yamaton-Liver project demonstrated the proof of concept by showing that rat-mouse chimeric livers could develop in mice and be successfully transplanted into syngeneic or allogeneic rats. Under conventional immunosuppression, the transplanted livers showed long-term function and protection against rejection. Because chimeric liver grafts have xenogeneic components, additional strategies, such as humanization of pig genes, induction of hematopoietic chimeras in donors, and replacement of pig endothelial cells with human ones, might be required in clinical use. Our projects still need to overcome various hurdles but can bring huge benefits to patients in the future. PMID:23896578

  17. Postreperfusion syndrome during liver transplantation

    2015-01-01

    As surgical and graft preservation techniques have improved and immunosuppressive drugs have advanced, liver transplantation (LT) is now considered the gold standard for treating patients with end-stage liver disease worldwide. However, despite the improved survival following LT, severe hemodynamic disturbances during LT remain a serious issue for the anesthesiologist. The greatest hemodynamic disturbance is postreperfusion syndrome (PRS), which occurs at reperfusion of the donated liver after unclamping of the portal vein. PRS is characterized by marked decreases in mean arterial pressure and systemic vascular resistance, and moderate increases in pulmonary arterial pressure and central venous pressure. The underlying pathophysiological mechanisms of PRS are complex. Moreover, risk factors associated with PRS are not fully understood. Rapid and appropriate treatment with vasopressors, volume replacement, or venesection must be provided depending on the cause of the hemodynamic disturbance when hemodynamic instability becomes profound after reperfusion. The negative effects of PRS on postoperative early morbidity and mortality are clear, but the effect of PRS on postoperative long-term mortality remains a matter of debate. PMID:26634075

    Within the field of regenerative medicine, the liver is of major interest for adoption of regenerative strategies due to its well-known and unique regenerative capacity. Whereas therapeutic strategies such as liver resection and orthotopic liver transplantation (OLT) can be considered standards of care for the treatment of a variety of liver diseases, the concept of liver cell transplantation (LCTx) still awaits clinical breakthrough. Success of LCTx is hampered by insufficient engraftment/long-term acceptance of cellular allografts mainly due to rejection of transplanted cells. This is in contrast to the results achieved for OLT where long-term graft survival is observed on a regular basis and, hence, the liver has been deemed an immune-privileged organ. Immune responses induced by isolated hepatocytes apparently differ considerably from those observed following transplantation of solid organs and, thus, LCTx requires refined immunological strategies to improve its clinical outcome. In addition, clinical usage of LCTx but also related basic research efforts are hindered by the limited availability of high quality liver cells, strongly emphasizing the need for alternative cell sources. This review focuses on the various immunological aspects of LCTx summarizing data available not only for hepatocyte transplantation but also for transplantation of non-parenchymal liver cells and liver stem cells.

    Liver dysfunction occurs after bone marrow transplantation but the relative importance of graft versus host disease and other factors, such as infection, radiation, and drugs, has not been clearly established. We have studied liver status before and after bone marrow transplantation in 43 consecutive patients and have related this to survival and factors that are recognised to cause liver injury. Minor abnormalities of liver tests occurred in 21% of patients before grafting but this did not influence survival or the development of liver disease after transplantation. During the first 50 days after grafting, 83% of patients had abnormal liver tests which were more severe in patients who subsequently died. Alanine transaminase was significantly higher in non-survivors and appeared to predict survival early after transplantation. Only non-survivors developed clinical signs of liver disease. Severe liver disease was always associated with graft versus host disease and atypia of the small bile ducts was the most useful histological marker of hepatic involvement with this disease. Two of the patients with hepatic graft versus host disease also has hepatic veno-occlusive disease and three fatalities had opportunistic infection of the liver, although, in the latter, death was not due primarily to liver dysfunction. Previous hepatitis and androgen therapy could not be implicated as important causes of hepatic damage but chemotherapy for acute leukaemia and conditioning regimens for bone marrow transplantation appear to be the most important factors in the development of hepatic veno-occlusive disease.

    Liver transplantation is currently in its golden period in India. The number of transplants being performed and the steady increase in the new programs that have emerged over the last decade is a testimony to it. The growth was not smooth, especially in the early years. But a multipronged approach in developing infrastructure and the involvement of multidisciplinary teams in the management of transplant patients has had a major positive impact on the outcome and as a result a positive impetus to the growth of this specialty in India. To date, the majority of transplants performed in India are live donor liver transplants. Deceased donation is more sporadic and concentrated in a couple of regions. With phenomenal increase in transplant activity in India, there is huge potential for streamlining data sharing among programs in India and with the rest of the world to ultimately benefit the transplant community.

    Liver transplantation (LT) is the most effective treatment modality for end stage liver disease caused by many etiologies including autoimmune processes. That said, the need for transplantation for autoimmune hepatitis (AIH) and primary biliary cirrhosis (PBC), but not for primary sclerosing cholangitis (PSC), has decreased over the years due to the availability of effective medical treatment. Autoimmune liver diseases have superior transplant outcomes than those of other etiologies. While AIH and PBC can recur after LT, recurrence is of limited clinical significance in most, but not all cases. Recurrent PSC, however, often progresses over years to a stage requiring re-transplantation. The exact incidence and the predisposing factors of disease recurrence remain debated. Better understanding of the pathogenesis and the risk factors of recurrent autoimmune liver diseases is required to develop preventive measures. In this review, we discuss the current knowledge of incidence, diagnosis, risk factors, clinical course, and treatment of recurrent autoimmune liver disease (AIH, PBC, PSC) following LT.

    Small-for-size grafts are an issue in liver transplantation. Portal venous pressure (PVP) was monitored and intentionally controlled during living-donor liver transplantation (LDLT) in 155 adult recipients. The indocyanine green elimination rate (kICG) was simultaneously measured in 16 recipients and divided by the graft weight (g) to reflect portal venous flow (PVF). The target PVP was <20 mmHg. Patients were divided by the final PVP (mmHg): Group A, PVP < 12; Group B, 12 ≤ PVP < 15; Group C, 15 ≤ PVP < 20; and Group D, PVP ≥ 20. With intentional PVP control, we performed splenectomy and collateral ligation in 80 cases, splenectomy in 39 cases, and splenectomy, collateral ligation, and additional creation in five cases. Thirty-one cases received no modulation. Groups A and B showed good LDLT results, while Groups C and D did not. Final PVP was the most important factor for the LDLT results, and the PVP cutoffs for good outcomes and clinical courses were both 15.5 mmHg. The respective kICG/graft weight cutoffs were 3.5580 × 10(-4) /g and 4.0015 × 10(-4) /g. Intentional PVP modulation at <15 mmHg is a sure surgical strategy for small-for-size grafts, to establish greater donor safety with good LDLT results. The kICG/graft weight value may have potential as a parameter for optimal PVF and a predictor for LDLT results. PMID:22686957

    Chronic liver disease has an important effect on nutritional status, and malnourishment is almost universally present in patients with end-stage liver disease who undergo liver transplantation. During recent decades, a trend has been reported that shows an increase in number of patients with end-stage liver disease and obesity in developed countries. The importance of carefully assessing the nutritional status during the work-up of patients who are candidates for liver replacement is widely recognised. Cirrhotic patients with depleted lean body mass (sarcopenia) and fat deposits have an increased surgical risk; malnutrition may further impact morbidity, mortality and costs in the post-transplantation setting. After transplantation and liver function is restored, many metabolic alterations are corrected, dietary intake is progressively normalised, and lifestyle changes may improve physical activity. Few studies have examined the modifications in body composition that occur in liver recipients. During the first 12 mo, the fat mass progressively increases in those patients who had previously depleted body mass, and the muscle mass recovery is subtle and non-significant by the end of the first year. In some patients, unregulated weight gain may lead to obesity and may promote metabolic disorders in the long term. Careful monitoring of nutritional changes will help identify the patients who are at risk for malnutrition or over-weight after liver transplantation. Physical and nutritional interventions must be investigated to evaluate their potential beneficial effect on body composition and muscle function after liver transplantation. PMID:25152572

    Liver transplantation (LT) is a life-saving treatment for patients with end-stage liver disease and for patients with liver cell cancer related to liver disease. Acute and chronic liver diseases related to hepatitis viruses are between the main indications for liver transplantation. The risk of viral reinfection after transplantation is the main limiting factor in these indications. Before the availability of antiviral prophylaxis, hepatitis B virus (HBV) recurrence was universal in patients who were HBV DNA-positive before transplantation. The natural history of recurrent HBV was accelerated by immunosuppression, and it progressed rapidly to graft failure and death. Introduction of post-transplant prophylaxis with immunoglobulin alone first, and associated to antiviral drugs later, drastically reduced HBV recurrence, resulting in excellent long-term outcomes. On the contrary, recurrence of hepatitis C is the main cause of graft loss in most transplant programs. Overall, patient and graft survival after LT for hepatitis C virus (HCV)-associated cirrhosis is inferior compared with other indications. However, successful pretransplant or post transplant antiviral therapy has been associated with increased graft and overall survival. Until recently, the combination of pegylated interferon and ribavirin was the standard of care for the treatment of patients with chronic hepatitis C. Highly active antiviral compounds have been developed over the past decade, thanks to new in vitro systems to study HCV entry, replication, assembly, and release. PMID:26819523

    The widespread recognition of the success of liver transplantation as a treatment for most types of acute and chronic liver failure has led to increased referrals for transplantation in the setting of a relatively fixed supply of cadaver donor organs. These events have led to a marked lengthening of the waiting time for liver transplantation, resulting in increased deaths of those on the waiting list and sicker patients undergoing transplantation. Nearly 5000 liver transplantations were performed in the United States in 2000, while the waiting list grew to over 17,000 patients. The mounting disparity between the number of liver transplant candidates and the limited supply of donor organs has led to reassessment of the selection and listing criteria for liver transplantation, as well as revision of organ allocation and distribution policies for cadaver livers. The development of minimal listing criteria for patients with chronic liver disease based on a specific definition for decompensation of cirrhosis has facilitated the more uniform listing of patients at individual centres across the United States. The United Network for Organ Sharing, under pressure from transplant professionals, patient advocacy groups and the federal government, has continuously revised allocation and distribution policies based on the ethical principles of justice for the individual patient versus optimal utility of the limited organ supply available annually. Beginning in 2002, it is likely that the Model for End-stage Liver Disease (MELD) score will be implemented to determine disease severity and direct donor organs to the sickest patients rather than to those with the longest waiting times.

    Pregnancy in patients with advanced liver disease is uncommon as most women with decompensated cirrhosis are infertile and have high rate of anovulation. However, if gestation ensued; it is very challenging and carries high risks for both the mother and the baby such as higher rates of spontaneous abortion, prematurity, pulmonary hypertension, splenic artery aneurysm rupture, postpartum hemorrhage, and a potential for life-threatening variceal hemorrhage and hepatic decompensation. In contrary, with orthotopic liver transplantation, menstruation resumes and most women of childbearing age are able to conceive, give birth and lead a better quality of life. Women with orthotopic liver transplantation seeking pregnancy should be managed carefully by a team consultation with transplant hepatologist, maternal-fetal medicine specialist and other specialists. Pregnant liver transplant recipients need to stay on immunosuppression medication to prevent allograft rejection. Furthermore, these medications need to be monitored carefully and continued throughout pregnancy to avoid potential adverse effects to mother and baby. Thus delaying pregnancy 1 to 2 years after transplantation minimizes fetal exposure to high doses of immunosuppressants. Pregnant female liver transplant patients have a high rate of cesarean delivery likely due to the high rate of prematurity in this population. Recent reports suggest that with close monitoring and multidisciplinary team approach, most female liver transplant recipient of childbearing age will lead a successful pregnancy. PMID:24282354

    Chronic liver disease is one of the leading causes of mortality and morbidity in the worldwide adult population. Liver transplant is the gold standard therapy for end-stage liver disease and many patients are on the waiting list for a transplant. A variety of pulmonary disorders are encountered in cirrhotic patients. Pleura, lung parenchyma, and pulmonary vasculature may be affected in these patients. Hypoxemia is relatively common and can be asymptomatic. Hepatopulmonary syndrome should be investigated in hypoxic cirrhotic patients. Gas exchange abnormalities are common and are generally correlated with the severity of liver disease. Both obstructive and restrictive types of airway disease can be present. Abnormal diffusion capacity is the most frequently observed pulmonary function disorder in patients with cirrhosis. Hepatic hydrothorax is another finding which is usually seen in conjunction with, but occasionally without ascites. Portopulmonary hypertension is a complication of long standing liver dysfunction and when severe, is accepted as a containdication to liver transplant. Since respiratory disorders are common and have significant impact on postoperative outcome in patients undergoing liver transplant, a careful preoperative pulmonary assessment is important.

    Living donor liver transplant (LDLT) accounts for a small volume of the transplants in the USA. Due to the current liver allocation system based on the model for end-stage liver disease (MELD), LDLT has a unique role in providing life-saving transplantation for patients with low MELD scores and significant complications from portal hypertension, as well as select patients with hepatocellular carcinoma (HCC). Donor safety is paramount and has been a topic of much discussion in the transplant community as well as the general media. The donor risk appears to be low overall, with a favorable long-term quality of life. The latest trend has been a gradual shift from right-lobe grafts to left-lobe grafts to reduce donor risk, provided that the left lobe can provide adequate liver volume for the recipient.

    Liver transplantation in rats is frequently used as a transplantation model. Although liver transplantation in larger laboratory animals such as dogs and pigs is technically easier, the rat has become the most important subject for experimental liver transplantation because of the availability of genetically defined animals. Numerous surgical techniques have been developed that permit the investigator to carry out studies with high clinical relevance. In this article the principal models of orthotopic rat liver transplantation and their technical modifications of vessel anastomoses, rearterialization, and bile duct reconstruction techniques are reviewed. More than 20 transplantation models are described in detail and demonstrated with clear illustrations. Finally, the advantages and uses of all the surgical procedures (e.g., suture and cuff anastomoses, bile duct anastomoses, and rearterialization techniques), specific problems, and survival criteria are discussed and the experiences of investigators who applied these techniques are analyzed. In conclusion, an overview and critical evaluation of all surgical techniques of orthotopic rat liver transplantation are given, together with instructions for learning these techniques.

    Pulmonary vascular disorders including portopulmonary hypertension (PoPHT) are among the common complications of liver disease and are prognostically significant. Survival is very low without medical treatment and liver transplantation. With advances in medical therapy for elevated pulmonary artery pressure (PAP) and liver transplant surgery, survival of patients with PoPHT and advanced liver disease is significantly improved. Because of the prognostic significance of PoPHT and the limited donor pool, a comprehensive preoperative cardio-pulmonary assessment is of great importance in cirrhotic patients prior to transplant surgery. Therefore, a detailed transthoracic Doppler echocardiographic examination must be an essential component of this evaluation. Patients with mild PoPHT can safely undergo liver transplant surgery. In cases of moderate to severe PoPHT, right heart catheterization (RHC) should be performed. In patients with moderate to severe PoPHT on RHC (mean PAP 35-45 mmHg), vasodilator therapy should be attempted. Liver transplantation should be encouraged in cases that demonstrate a positive response. Bridging therapy with specific pulmonary arterial hypertension treatment agents should be considered until the transplant surgery and should be continued during the peri- and post-operative periods as needed.

    A liver from a donor with brain death due to a ruptured cerebral aneurysm was transplanted. The liver had multiple bilobar simple cysts; the largest was less than 3 cm in diameter. The noncystic liver volume was greater than 50%, and the liver had neither fibrosis nor venous congestion. The donor surgery was performed in accordance with the standard protocol without rupture of the cysts. The recipient was a 40-year-old man with cirrhosis associated with hepatitis B. The recipient operation was done by using the piggyback method with no complications. Excessive drainage of chylous ascites (10 000 mL/d) started in the first days after surgery and continued, gradually decreasing until the end of the second month. The patient was discharged with no complications at the end of the third month. No growth in the cysts was observed on follow-up computed tomography scans. Excluding this particular case, a total of 7 other patients have received a polycystic liver transplant. In all 7 cases, the fact that the donor had polycystic liver disease was not known but was encountered by coincidence during procurement. The case reported here is the first case where the polycystic liver disease was diagnosed before procurement and the transplant was still carried out. It appears that, if the donor liver has enough healthy noncystic volume, polycystic livers can be transplanted. PMID:23782669

    The liver is the largest organ in the body; it has a complex architecture, wide range of functions and unique regenerative capacity. The growing incidence of liver diseases worldwide requires increased numbers of liver transplant and leads to an ongoing shortage of donor livers. To meet the huge demand, various alternative approaches are being investigated including, hepatic cell transplantation, artificial devices and bioprinting of the organ itself. Adult hepatocytes are the preferred cell sources, but they have limited availability, are difficult to isolate, propagate poor and undergo rapid functional deterioration in vitro. There have been efforts to overcome these drawbacks; by improving culture condition for hepatocytes, providing adequate extracellular matrix, co-culturing with extra-parenchymal cells and identifying other cell sources. Differentiation of human stem cells to hepatocytes has become a major interest in the field of stem cell research and has progressed greatly. At the same time, use of decellularized organ matrices and 3 D printing are emerging cutting-edge technologies for tissue engineering, opening up new paths for liver regenerative medicine. This review provides a compact summary of the issues, and the locations of liver support systems and tissue engineering, with an emphasis on reproducible and useful sources of hepatocytes including various candidates formed by differentiation from stem cells.

    In liver haemangiomas, the risk of complication rises with increasing size, and treatment can be obligatory. Here we present a case of a 46-year-old female who suffered from a giant haemangioma causing severe portal hypertension and vena cava compression, leading to therapy refractory ascites, hyponatremia and venostasis-associated thrombosis with pulmonary embolism. The patients did not experience tumour rupture or consumptive coagulopathy. Surgical resection was impossible because of steatosis of the non-affected liver. Orthotopic liver transplantation was identified as the only treatment option. The patient’s renal function remained stable even though progressive morbidity and organ allocation were improbable according to the patient’s lab model for end-stage liver disease (labMELD) score. Therefore, non-standard exception status was approved by the European organ allocation network “Eurotransplant”. The patient underwent successful orthotopic liver transplantation 16 mo after admission to our centre. Our case report indicates the underrepresentation of morbidity associated with refractory ascites in the labMELD-based transplant allocation system, and it indicates the necessity of promptly applying for non-standard exception status to enable transplantation in patients with a severe clinical condition but low labMELD score. Our case highlights the fact that liver transplantation should be considered early in patients with non-resectable, symptomatic benign liver tumours. PMID:26722664

    Protein-energy malnutrition is frequently seen in patients with end-stage liver disease who undergo liver transplantation. This causes a deterioration of the patients' clinical condition and affects their post-transplantation survival. Accurate assessment of the nutritional status and adequate intervention are prerequisites for perioperative nutritional treatment. However, the metabolic abnormalities induced by liver failure make the traditional assessment of the nutritional status difficult. The methods that were recently developed for accurately assessing the nutritional status by body bioelectrical impedance may be implemented in pre-transplant management. Because preoperative malnutrition and the loss of skeletal muscle mass, called sarcopenia, have a significant negative impact on the post-transplantation outcome, it is essential to provide adequate nutritional support during all phases of liver transplantation. Oral nutrition is preferred, but tube enteral nutrition may be required to provide the necessary caloric intake. We herein discuss both bioelectrical impedance and the latest findings in the current perioperative nutritional interventions in liver transplant patients regarding synbiotics, micronutrients, branched-chain amino acid supplementation, the use of immune system modulating formulas, the fluid balance and the offering of nocturnal meals.

    Non-alcoholic steatohepatitis is a growing liver-related health problem. In Europe, non-alcoholic fatty liver disease is the most usual reason of chronic liver illness while steatohepatitis, its progressive form, affects 1% of Europeans and North Americans. In the United States steatohepatitis-related cirrhosis is one of the main indications for liver transplant. A targeted stratification for patients waiting for transplant and affected by this disease is mandatory especially because of their increased cardiovascular and cancer risk. The adequate treatment of NAFLD is crucial for the reduction of the disease related morbidity and mortality. In post-transplant setting, the recurrent or de novo steatosis might seriously affect the allograft short- and long-term outcome. Many conditions can represent the basis of the post-transplant steatohepatitis: obesity, hyperlipidaemia, diabetes mellitus, arterial hypertension, immunosuppressant treatment, alcoholic habit and liver graft steatosis. Today, the only consolidated therapy is represented by a deep life-style intervention since the use of drug-based alternative strategies is still limited and a very few data are available for the post-transplant period. Targeted and personalized behaviour and pharmacological interventions have to be developed for both the pre- and post-transplant phase. PMID:27038703

  1. Management of Biliary Strictures After Liver Transplantation

    2015-01-01

    Strictures of the bile duct are a well-recognized complication of liver transplant and account for more than 50% of all biliary complications after deceased donor liver transplant and living donor liver transplant. Biliary strictures that develop after transplant are classified as anastomotic strictures or nonanastomotic strictures, depending on their location in the bile duct. The incidence, etiology, natural history, and response to therapy of the 2 types vary greatly, so their distinction is clinically important. The imaging modality of choice for the diagnosis of biliary strictures is magnetic resonance cholangiopancreatography because of its high rate of diagnostic accuracy and limited risk of complications. Biliary strictures that develop after liver transplant may be managed with endoscopic retrograde cholangiography (ERC), percutaneous transhepatic cholangiography (PTC), or surgical revision, including retransplant. The initial treatment of choice for these strictures is ERC with progressive balloon dilation and the placement of increasing numbers of plastic stents. PTC and surgery are generally reserved for failures of endoscopic therapy or for anatomic variants that are not suitable for ERC. In this article, we discuss the classification of biliary strictures, their diagnosis, and the therapeutic strategies that can be used to manage these common complications of liver transplant.

    Living donor liver transplantation (LDLT) sparked significant interest in Europe when the first reports of its success from USA and Asia were made public. Many transplant programs initiated LDLT and some of them especially in Germany and Belgium became a point of reference for many patients and important contributors to the advancement of the field. After the initial enthusiasm, most of the European programs stopped performing LDLT and today the overall European activity is concentrated in a few centers and the number of living donor liver transplants is only a single digit fraction of the overall number of liver transplants performed. In this paper we analyse the present European activities and highlight the European contribution to the advancement of the field of LDLT. PMID:27115011

  3. Future Economics of Liver Transplantation: A 20-Year Cost Modeling Forecast and the Prospect of Bioengineering Autologous Liver Grafts.

    2015-01-01

    During the past 20 years liver transplantation has become the definitive treatment for most severe types of liver failure and hepatocellular carcinoma, in both children and adults. In the U.S., roughly 16,000 individuals are on the liver transplant waiting list. Only 38% of them will receive a transplant due to the organ shortage. This paper explores another option: bioengineering an autologous liver graft. We developed a 20-year model projecting future demand for liver transplants, along with costs based on current technology. We compared these cost projections against projected costs to bioengineer autologous liver grafts. The model was divided into: 1) the epidemiology model forecasting the number of wait-listed patients, operated patients and postoperative patients; and 2) the treatment model forecasting costs (pre-transplant-related costs; transplant (admission)-related costs; and 10-year post-transplant-related costs) during the simulation period. The patient population was categorized using the Model for End-Stage Liver Disease score. The number of patients on the waiting list was projected to increase 23% over 20 years while the weighted average treatment costs in the pre-liver transplantation phase were forecast to increase 83% in Year 20. Projected demand for livers will increase 10% in 10 years and 23% in 20 years. Total costs of liver transplantation are forecast to increase 33% in 10 years and 81% in 20 years. By comparison, the projected cost to bioengineer autologous liver grafts is $9.7M based on current catalog prices for iPS-derived liver cells. The model projects a persistent increase in need and cost of donor livers over the next 20 years that's constrained by a limited supply of donor livers. The number of patients who die while on the waiting list will reflect this ever-growing disparity. Currently, bioengineering autologous liver grafts is cost prohibitive. However, costs will decline rapidly with the introduction of new manufacturing

    Cirrhosis secondary to non-alcoholic steatohepatitis (NASH) is a common indication for liver transplant. In comparison to other cirrhotic patients, patients with NASH cirrhosis are more likely to be older and have the metabolic syndrome. Pre-transplant, patients require careful evaluation of cardiovascular risk. As the incidence of non-alcoholic fatty liver disease (NAFLD) is rising, a greater proportion of donor grafts have steatosis greater than 30%, which is associated with poor outcomes. Grafts with steatosis greater than 60% are unsuitable for transplant. Overall, post-transplant survival outcomes for patients with NASH cirrhosis are similar to those with cirrhosis without NASH. However, NASH cirrhosis is associated with a higher 30-day mortality, predominantly from an increase in cardiovascular events and infections. Following liver transplant, there is a significant risk of NASH recurrence, although this seldom results in allograft loss. Furthermore, a significant number of patients who had a liver transplant for other reasons develop NASH de novo. When patients with NASH cirrhosis are considered for transplant, one of the major challenges lies in identifying which patients are too high risk for surgery. This review aims to provide information to aid this decision making process, and to provide guidance on the peri-operative care strategies that can modify risk. PMID:26997540

    With the evolution of surgical and anesthetic techniques, liver transplantation has become "routine," allowing for modifications of practice to decrease perioperative complications and costs. There is debate over the necessity for intensive care unit admission for patients with satisfactory preoperative status and a smooth intraoperative course. Postoperative care is made easier when the liver graft performs optimally. Assessment of graft function, vigilance for complications after the major surgical insult, and optimization of multiple systems affected by liver disease are essential aspects of postoperative care. The intensivist plays a vital role in an integrated multidisciplinary transplant team. PMID:27339683

    In the current Model for End-Stage Liver Disease system, patients with polycystic liver disease (PCLD) who have a poor quality of life secondary to their massive hepatomegaly are no longer competitive for a deceased donor liver transplant if their liver function is well preserved. Traditionally, a caval resection has been advocated in these patients because of the difficulty of the hepatectomy with hepatomegaly, which makes living donation impossible. This series looks at 3 patients who underwent a caval sparing hepatectomy and subsequent living donor liver transplantation (LDLT) for PCLD. Graft and patient survival was 100%, and there were few complications in either donors or recipients. LDLT is an ideal option for patients with PCLD and preserved liver function but poor quality of life. PMID:18433036

    Living donor liver transplantation (LDLT) is a very successful procedure that develops liver resources in case of worldwide shortages. As the technology has developed so much in the past 2 decades, LDLT has the same good prognosis as DDLT. However, LDLT still has lots of ethical & technical problems. It causes great psychiatric, physical and psychosocial harm to donors. Also, it has some negative effects on society by providing a platform for organ trade. Therefore, there is much controversy about the social value of LDLT. After review of recent papers, we find much progress can be made in inspiring the public to become organ donors and creating donation model new to improve the consent rate for solid organ donation from deceased donors. That is the key strategy for increasing the liver supply. With this serious shortage of organs, liver donor transplantation still has its advantages, but we should not place all our hopes on LDLT to increase the liver supply. We all need to try our best to increase donor awareness and promote organ donor registration--when cadaver organs could meet the needs for liver transplantation, living donor liver transplants would not be necessary.

    Liver failure is a heterogeneous condition which may be fatal and the primary cause is frequently unknown. We investigated mitochondrial oxidative phosphorylation in patients undergoing liver transplantation. We studied 45 patients who had liver transplantation due to a variety of clinical presentations. Blue native polyacrylamide gel electrophoresis with immunodetection of respiratory chain complexes I-V, biochemical activity of respiratory chain complexes II and IV and quantification of mitochondrial DNA (mtDNA) copy number were investigated in liver tissue collected from the explanted liver during transplantation. Abnormal mitochondrial function was frequently present in this cohort: ten of 40 patients (25 %) had a defect of one or more respiratory chain enzyme complexes on blue native gels, 20 patients (44 %) had low activity of complex II and/or IV and ten (22 %) had a reduced mtDNA copy number. Combined respiratory chain deficiency and reduced numbers of mitochondria were detected in all three patients with acute liver failure. Low complex IV activity in biliary atresia and complex II defects in cirrhosis were common findings. All six patients diagnosed with liver tumours showed variable alterations in mitochondrial function, probably due to the heterogeneity of the presenting tumour. In conclusion, mitochondrial dysfunction is common in severe liver failure in non-mitochondrial conditions. Therefore, in contrast to the common practice detection of respiratory chain abnormalities in liver should not restrict the inclusion of patients for liver transplantation. Furthermore, improving mitochondrial function may be targeted as part of a complex therapy approach in different forms of liver diseases. PMID:27053192

    Background : Appendicitis is a common cause of emergency surgery that in the population undergoing organ transplantation presents a rare incidence due to late diagnosis and treatment. Aim : To report the occurrence of acute appendicitis in a cohort of liver transplant recipients. Methods : Retrospective analysis in a period of 12 years among 925 liver transplants, in witch five cases of acute appendicitis were encountered. Results : Appendicitis occurred between three and 46 months after liver transplantation. The age ranged between 15 and 58 years. There were three men and two women. The clinical presentations varied, but not discordant from those found in non-transplanted patients. Pain was a symptom found in all patients, in two cases well located in the right iliac fossa (40%). Two patients had symptoms characteristic of peritoneal irritation (40%) and one patient had abdominal distention (20%). All patients were submitted to laparotomies. In 20% there were no complications. In 80% was performed appendectomy complicated by suppuration (40%) or perforation (40%). Superficial infection of the surgical site occurred in two patients, requiring clinical management. The hospital stay ranged from 48 h to 45 days. Conclusion : Acute appendicitis after liver transplantation is a rare event being associated with a high rate of drilling, due to delays in diagnosis and therapy, and an increase in hospital stay.

    Background Many concerns about liver transplantation in alcoholic patients are related to the risk of alcohol recidivism. Starting from 2002, an Alcohol Addiction Unit was formed within the Liver Transplant Centre for the management of alcoholic patients affected by end-stage liver disease and included in the waiting list for transplantation. We evaluated retrospectively the impact of the Alcohol Addiction Unit on alcohol recidivism after transplantation. The relationship between alcohol recidivism and the duration of alcohol abstinence before transplant was evaluated as well. Methods Between 1995 and 2010, 92 cirrhotic alcoholic patients underwent liver transplantation. Clinical evaluation and management of alcohol use in these patients was provided by psychiatrists with expertise in addiction medicine not affiliated to the Liver Transplant Centre before 2002 (n=37; group A), or by the clinical staff of the Alcohol Addiction Unit within the Liver Transplant Centre starting from 2002 (n=55; group B). Results Group B, as compared to group A, showed a significantly lower prevalence of alcohol recidivism (16.4% vs. 35.1%; p=0.038) and a significantly lower mortality (14.5% vs. 37.8%; p=0.01). Furthermore, an analysis of group B patients with either ≥6 months or <6 months of alcohol abstinence before transplantation showed no difference in the rate of alcohol recidivism (21.1% vs. 15.4%; p=ns). Conclusions The presence of an Alcohol Addiction Unit within a Liver Transplant Centre reduces the risk of alcohol recidivism after transplantation. A pre-transplant abstinence period <6 months might be considered, at least in selected patients managed by an Alcohol Addiction Unit. PMID:23578009

    With the growing number of patients in need of liver transplantation, there is a need for adopting new and modifying existing allocation policies that prioritize patients for liver transplantation. Policy should ensure fair allocation that is reproducible and strongly predictive of best pre and post transplant outcomes while taking into account the natural history of the potential recipients liver disease and its complications. There is wide acceptance for allocation policies based on urgency in which the sickest patients on the waiting list with the highest risk of mortality receive priority. Model for end-stage liver disease and Child-Turcotte-Pugh scoring system, the two most universally applicable systems are used in urgency-based prioritization. However, other factors must be considered to achieve optimal allocation. Factors affecting pre-transplant patient survival and the quality of the donor organ also affect outcome. The optimal system should have allocation prioritization that accounts for both urgency and transplant outcome. We reviewed past and current liver allocation systems with the aim of generating further discussion about improvement of current policies. PMID:26973389

    Purpose Metabolic liver disease (MLD) often progresses to life-threatening conditions. This study intends to describe the outcomes of liver transplantation (LTx) for MLD at a living donor-dominant transplantation center where potentially heterozygous carrier grafts are employed. Methods We retrospectively evaluated the medical records of 54 patients with MLD who underwent LTx between November 1995 and February 2012 at Asan Medical Center in Seoul, Korea. The cumulative graft and patient survival rates were analyzed according to patient age, and living or deceased donor LTx. Recurrence of the original disease was also investigated. Results The post-transplant cumulative patient survival rates at one, five, and 10 years were 90.7%, 87.5% and 87.5%, and the graft survival rates were 88.8%, 85.5%, and 85.5%, respectively. There were no differences in the patient survival rates according to the recipient age, human leukocyte antigen matching, and living or deceased donor LTx. There were also no differences in the patient survival rates between the MLD and the non-MLD groups for children. Recurrence of the original metabolic disease was not observed in any patient during the follow-up period. Conclusion Our results suggest that the living donor-dominant transplantation program is well-tolerated in MLD without recurrence of the original MLD using all types of transplantation.

    In Europe, 30% to 50% of liver transplantations are currently due to alcoholic liver disease (ALD). In the United States, this percentage is 17.2%. Post-transplant survival and other predictors of clinical course do not differ significantly from those in other types of transplanted patients, as long as there is no relapse of drinking. However, 20%-25% of these patients lapse or relapse to heavy drinking post-operatively, which has been associated with an increased risk of liver damage and mortality. It is therefore crucial to design specific selection and follow-up strategies aimed at this particular type of patient. Several good and poor prognosis factors that could help to predict a relapse have been suggested, among them the duration of abstinence, social support, a family history of alcoholism, abuse diagnosis versus alcohol dependence, non-acceptance of diagnosis related to alcohol use, presence of severe mental illness, non-adherence in a broad sense, number of years of alcoholism, and daily quantity of alcohol consumption. In this article, we discuss these and other, more controversial factors in selecting ALD patients for liver transplantation. Abstinence should be the main goal after transplantation in an ALD patient. In this article, we review the several definitions of post-transplant relapse, its monitoring and the psychopharmacological and psychotherapeutic treatment. PMID:26494959

    Great progress has been made in the field of liver transplantation over the past two decades. This progress, however, also brings up the next set of challenges: First, organ shortage remains a major limitation, and accounts for a large proportion of wait list mortality. While living donation has successfully increased the total number of liver transplants done in Asian countries, the total number of such transplants has been stagnant in the western hemisphere. As such, there has been a significant effort over the past decade to increase the existing deceased donor pool. This effort has resulted in a greater use of liver allografts following donation after cardiac death (DCD) along with marginal and extended criteria donors. Improved understanding of the pathophysiology of liver allografts procured after circulatory arrest has not only resulted in better selection and management of DCD donors, but has also helped in the development of mechanical perfusion strategies. Early outcomes demonstrating the clinical applicability of both hypothermic and normothermic perfusion and its potential to impact patient survival and allograft function have generated much interest. Second, long-term outcomes of liver transplant recipients have not improved significantly, as recipients continue to succumb to complications of long-term immunosuppression, such as infection, malignancy and renal failure. Furthermore, recent evidence suggests that chronic immune-mediated injury to the liver may also impact graft function. PMID:27182155

While living donation has successfully increased the total number of liver transplants done in Asian countries, the total number of such transplants has been stagnant in the western hemisphere. As such, there has been a significant effort over the past decade to increase the existing deceased donor pool. This effort has resulted in a greater use of liver allografts following donation after cardiac death (DCD) along with marginal and extended criteria donors. Improved understanding of the pathophysiology of liver allografts procured after circulatory arrest has not only resulted in better selection and management of DCD donors, but has also helped in the development of mechanical perfusion strategies. Early outcomes demonstrating the clinical applicability of both hypothermic and normothermic perfusion and its potential to impact patient survival and allograft function have generated much interest. Second, long-term outcomes of liver transplant recipients have not improved significantly, as recipients continue to succumb to complications of long-term immunosuppression, such as infection, malignancy and renal failure. Furthermore, recent evidence suggests that chronic immune-mediated injury to the liver may also impact graft function. PMID:27182155

    Given the malnutrition present in patients suffering from advanced hepatic illness, as well as the implications of this in the post-hepatic transplant period, a study was made of various biochemical parameters (prealbumin, retinol-bound protein, zinc, magnesium, cholesterol and amino acid pattern) as indicators of the nutritional condition of a series of 15 patients who underwent hepatic transplants and required total parenteral nutrition (TPN) during the first 10 post-transplant days. Before the transplants were carried out, all the patients studied showed a decrease in all evaluated parameters. Ten days after the transplant, and having been fed parenterally during this time, the different parameters corrected themselves, with the exception of cholesterol. TPN, administered with enrichment of branched amino acids by 35%, practically normalized the plasma amino acid pattern. PMID:1764532

    Liver transplant can be challenging in cirrhotic patients with diabetes mellitus. In chronic liver disease, the glucose metabolism is altered; uncontrolled diabetes negatively influences the outcome of liver transplantation and poses difficulty in the management of immediate post transplantation period. Simultaneous liver-pancreas transplantation is an option to prevent early complications due to diabetes and also to improve the quality of life after transplantation in patients with Insulin-Dependent Diabetes Mellitus (IDDM) and chronic liver disease. We report the first en-bloc liver-pancreas transplant done in the transplant history of Iran. We describe the technical details of the procedure as well as the short term outcome after transplantation. In this case report, we also discuss in some details, the surgical, medical and immunological advantages of combined liver-pancreas transplantation as opposed to separate implantation of both organs.

    Transplantation for Wilson's disease occupies 1/3 of the cases for metabolic diseases in Japan. At the end of 2009, 109 transplantations had been performed including three deceased donor cases in the Japanese registry. We herein discuss problems of transplantation for Wilson's disease as well as its indication, timing, and social care. We retrospectively reviewed four fulminant cases and two chronic cases who underwent living donor liver transplantation. There were two boys and two girls. Four adolescents of average age 11.3 years underwent living donor liver transplantation. Duration from onset to transplantation ranged from 10 to 23 days. Average Model for End-stage Liver Disease (MELD) score was 27.8 (range=24-31). All patients were administrated chelates prior to transplantation. MELD, New Wilson's index, Japanese scoring for liver transplantation, and liver atrophy were useful tools for transplantation decision making; however, none of them was an independent decisive tool. Clinical courses after transplantation were almost uneventful. One girl, however, developed an acute rejection episode due to noncompliance at 3 years after transplantation. All patients currently survive without a graft loss. No disease recurrence had been noted even using living related donors. Two adults evaluated for liver transplantation were listed for deceased donor liver transplantation. Both candidates developed cirrhosis despite long-term medical treatment. There were no appropriate living donors for them. There are many problems in transplantation for Wilson's disease. The indications for liver transplantation should be considered individually using some decision-making tools. The safety of the living donor should be paid the most attention. PMID:22410050

    A model that can accurately predict post-liver transplant mortality would be useful for clinical decision making, would help to provide patients with prognostic information, and would facilitate fair comparisons of surgical performance between transplant units. A systematic review of the literature was carried out to assess the quality of the studies that developed and validated prognostic models for mortality after liver transplantation and to validate existing models in a large data set of patients transplanted in the United Kingdom (UK) and Ireland between March 1994 and September 2003. Five prognostic model papers were identified. The quality of the development and validation of all prognostic models was suboptimal according to an explicit assessment tool of the internal, external, and statistical validity, model evaluation, and practicality. The discriminatory ability of the identified models in the UK and Ireland data set was poor (area under the receiver operating characteristic curve always smaller than 0.7 for adult populations). Due to the poor quality of the reporting, the methodology used for the development of the model could not always be determined. In conclusion, these findings demonstrate that currently available prognostic models of mortality after liver transplantation can have only a limited role in clinical practice, audit, and research.

    Acute-on-chronic liver failure is a clinical entity with high risk of mortality. These patients can have severe liver dysfunction complicated with multiple organ failure. Liver transplantation is the definitive treatment for these patients. Literature regarding management of acute liver failure with special emphasis on liver transplantation was reviewed. Lessons learnt from the management of patients with acute liver failure which could be extrapolated to the management of patients with acute-on-chronic liver failure are discussed. Significant improvement in outcomes of acute liver failure has been reported across the world. Several aspects in transplantation for acute liver failure were found to be relevant to the management of acute-on-chronic liver failure. These include defining criteria to identify patients needing early liver transplantation, prioritizing patients with acute liver failure on the waiting list, defining when to abandon transplantation in acute liver failure, emphasis on graft quality and the need for a multi-disciplinary approach to manage multiple organ dysfunction. Useful lessons can be learnt from the progress made in the management of acute liver failure and these can be extrapolated to the management of patients with acute-on-chronic liver failure.

    The intraoperative management of split liver transplantation (SLT) has some unique features as compared to routine whole liver transplantations. Only the liver has this special ability to regenerate that confers benefits in survival and quality of life for two instead of one by splitting livers. Primary graft dysfunction may result from small for size syndrome. Graft weight to recipient body weight ratio is significant for both trisegmental and hemiliver grafts. Intraoperative surgical techniques aim to reduce portal hyperperfusion and decrease venous portal pressure. Ischemic preconditioning can be instituted to protect against ischemic reperfusion injury which impacts graft regeneration. Advancement of the technique of SLT is essential as use of split cadaveric grafts expands the donor pool and potentially has an excellent future. PMID:26421261

    Background Liver transplantation is used to treat patients with irreversible liver failure from a variety of causes. Long-term survival has been reported, particularly in the paediatric population, with graft survival longer than 20 years now possible. The goal for paediatric liver transplantation is to increase the longevity of grafts to match the normal life expectancy of the child. This paper reviews the literature on the current understanding of ageing of the liver and biomarkers that may predict long-term survival or aid in utilization of organs. Methods Scientific papers published from 1950 to 2013 were sought and extracted from the MEDLINE, PubMed and University of Melbourne databases. Results Hepatocytes appear resistant to the ageing process, but are affected by both replicative senescence and stress-related senescence. These processes may be exacerbated by the act of transplantation. The most studied biomarkers are telomeres and SMP-30. Conclusion There are many factors that play a role in the ageing of the liver. Further studies into biomarkers of ageing and their relationship to the chronological age of the liver are required to aid in predicting long-term graft survival and utilization of organs.

    As the liver transplant journey in India reaches substantial numbers and suggests quality technical expertise, it is time to dispassionately look at the big picture, identify problems, and consider corrective measures for the future. Several features characterize the current scenario. Although the proportion of deceased donor liver transplants is increasing, besides major regional imbalances, the activity is heavily loaded in favor of the private sector and live donor transplants. The high costs of the procedure, the poor participation of public hospitals, the lack of a national registry, and outcomes reporting are issues of concern. Organ sharing protocols currently based on chronology or institutional rotation need to move to a more justiciable severity-based system. Several measures can expand the deceased donor pool. The safety of the living donor continues to need close scrutiny and focus. Multiple medical challenges unique to the Indian situation are also being thrown up. Although many of the deficits demand state intervention and policy changes the transplant community needs to take notice and highlight them. The future of liver transplantation in India should move toward a more accountable, equitable, and accessible form. We owe this to our citizens who have shown tremendous faith in us by volunteering to be living donors as well as consenting for deceased donation. PMID:26900275

    2012-11-01

    The disparity between the number of available deceased liver donors and the number of patients awaiting transplantation continues to be an ongoing issue predisposing to death on the liver transplant waiting list. Deceased donor shortage strategies including the use of extended donor-criteria deceased donor grafts, split liver transplants, and organs harvested after cardiac death have fallen short of organ demand. Efforts to raise donor awareness are ongoing, but the course has been arduous to date. Living donor transplantation is a means to access an unlimited donor organ supply and offers potential advantages to deceased donation. Donor safety remains paramount demanding improvements and innovations in both the donor and recipient operations to ensure superior outcomes. The specialty operation is best preformed at centers with specific expertise and shuttling of select patients to these centers supported by third party payers is critical. Training future surgeons at centers with this specific experience can help disseminate this technology to improve local availability. Ongoing research in immunosuppression minimization, withdrawal and tolerance induction may make living donation a desired first-line operation rather than a necessary albeit less-desirable option. This chapter summarizes the progress of living liver donation and its potential applications. PMID:23397534

    The metabolic syndrome (MS), which includes obesity, dyslipidaemia, hypertension and hyperglycaemia according to the most widely accepted definitions now used, is one of the most common post-transplant complications, with a prevalence of 44%-58%. The MS, together with the immunosuppression, is considered the main risk factor for the development of cardiovascular disease (CVD) in transplant recipients, which in turn accounts for 19%-42% of all deaths unrelated to the graft. The presence of MS represents a relative risk for the development of CVD and death of 1.78. On the other hand, non-alcoholic fatty liver disease (NAFLD), considered as the manifestation of the MS in the liver, is now the second leading reason for liver transplantation in the United States after hepatitis C and alcohol. NAFLD has a high rate of recurrence in the liver graft and a direct relation with the worsening of other metabolic disorders, such as insulin resistance or diabetes mellitus. Consequently, it is vitally important to identify and treat as soon as possible such modifiable factors as hypertension, overweight, hyperlipidaemia or diabetes in transplanted patients to thus minimise the impact on patient survival. Additionally, steroid-free regimens are favoured, with minimal immunosuppression to limit the possible effects on the development of the MS. PMID:27605877

    OBJECTIVE: To provide an approach to the care of liver transplant (LT) patients, a growing patient population with unique needs. METHODS: A literature search of PubMed for guidelines and review articles using the keywords “liver transplantation”, “long term complications” and “medical management” was conducted, resulting in 77 articles. RESULTS: As a result of being on immunosuppression, LT recipients are at increased risk of infections and must be screened regularly for metabolic complications and malignancies. DISCUSSION: Although immunosuppression is key to maintaining allograft health after transplantation, it comes with its own set of medical issues to follow. Physicians following LT recipients must be aware of the greater risk for hypertension, diabetes, dyslipidemia, renal failure, metabolic bone disease and malignancies in these patients, all of whom require regular monitoring and screening. Vaccination, quality of life, sexual function and pregnancy must be specifically addressed in transplant patients. PMID:24729996

    Background Studies on patients’ societal reintegration following orthotopic liver transplantation (OLT) are scarce. Methods Between September 2006 and January 2008, all adults who were alive after 3 years post OLT were included in this prospective cohort study. Validated questionnaires were administered to all candidates with the primary aim of investigating the rate of their social re-integration following OLT and potential barriers they might have encountered. Results Among 157 eligible patients 110 (70%) participated. Mean participants’ age was 57 years (SD 11.4) and 43% were females. Prior to OLT, 75% of patients were married and 6% were divorced. Following OLT there was no significant difference in marital status. Employment rate fell from 72% to 30% post-OLT. Patients who had been employed in either low-skill or advanced-skill jobs were less likely to return to work. After OLT, personal income fell an average of 4,363 Canadian dollars (CAN$) (SD 20,733) (P=0.03) but the majority of recipients (80%) reported high levels of satisfaction for their role in society. Conclusions Although patients’ satisfaction post-OLT is high, employment status is likely to be negatively affected for individuals who are not self-employed. Strategies to assist recipients in returning to their pre-OLT jobs should be developed to improve patients’ economical status and societal ability to recoup resources committed for OLT.

    The liver transplant program at the transplant center of Tianjin First Center Hospital opened in 1994 and has become a leading center for academic research and development in clinical liver transplantation during the past 18 years. As of Nov 30, 2011, we had performed 4,103 liver transplantations in patients ranging from 6 months to 79 years old. Since 1998, the program has ranked first in mainland China in the annual number of liver transplants performed, the cumulative total liver transplants and the number of long-surviving patients. We've accomplished a number of "firsts" among the Chinese liver transplant centers, including: the first split liver transplantation, the first pediatric liver transplant, the first living donor simultaneous liver-kidney transplant, the first dual-graft liver transplant using a domino right lobe and a living donor left lobe, the first laparoscopic assisted live donor right hepatectomy including the middle hepatic vein and we have assembled the first liver transplant chain comprising multiple donors and recipients. We have performed the largest number of living related and split liver transplantations in mainland China. The combined prophylactic protocol of "Lamivudine and HBIG" to prevent HBV recurrence post transplantation was first used by our center in China and now is utilized by most of the domestic transplant centers. We have begun using livers from donors after cardiac death (DCD) during the past 2 years, with careful donor selection and recipient management. All the approaches and techniques we've developed are aimed at the utilization of all types of available grafts. However, increasing the rate of transplantation with excellent graft and recipient survival are still the challenges facing us. PMID:22755414

    Background Although liver transplantation has been widely practised, post-operative bacterial infection is still a frequent complication which contributed to an increased risk of fatality. There were studies on preoperative use of probiotics for liver transplant patients and acquired reduction in postoperative sepsis and wound infection, but the relevant clinical experience with pre- and probiotics is still limited. Objectives This study is to assess fibre and probiotic use aimed at preventing bacterial sepsis and wound complications in patients undergoing liver transplantation. Study methods There were a total of sixty-seven adult patients scheduled for liver transplantation were included in a public teaching hospital. From January to December 2011, 34 continuous patients following liver transplantation were put on fibre + probiotics. In retrospectively, from January to December 2010, 33 continuous patients were collected as a control group and they were only received fibre post operation. The incidence of bacterial infections was compared in patients receiving either fibre and lactobacillus or fibre only. Statistical analysis was performed using SPSS 15. The t test, fisher’s and chi- square test was used to compare discrete variables. Results In summary, in the analysis of 67 liver transplant recipients, 8.8% group A patients developed infections compared to 30.3% group B patients. The difference between groups A and B was statistically significant in both cases. In addition, the duration of antibiotic therapy was significantly shorter in the lactobacillus-group. Wound infection was the most frequent infections and enterococci the most frequently isolated bacteria. Fibre and lactobacilli were well tolerated in most cases. The operating time, amount of intra- and post-operatively transfused units of blood, fresh frozen plasma and albumin did not differ significantly between the groups.

    2011-01-01

    About 27,000 deaths are registered annually in the United States due to liver disease. At this time, the only definitive treatment of hepatic failure is orthotopic transplantation. However, there is a critical shortage of organs with the total waiting list for all organs currently at 100,000 requests. The number is increasing by 5% every year. Given that only organs in pristine condition are transplantable and that the hidden demand for organs as an anti-aging solution will be many times the current figures, orthotopic transplantation will always remain a limited pool. The increasing donor organ shortage requires consideration of alternative emerging technologies. Regenerative medicine may offer novel strategies to treat patients with end-stage organ failure. The ultimate aim of cell transplantation, tissue engineering, and stem cells is to regenerate tissues and organs. With the development of whole organ decellularization methods, the equation of organ shortage may dramatically change in the near future. Decellularized organs provide the ideal transplantable scaffold with all the necessary microstructure and extracellular cues for cell attachment, differentiation, vascularization, and function. New techniques to re-engineer organs may have major implications for the fields of drug discovery, regeneration biology, and ultimately organ transplantation. In this review we have provided an overview of complementary approaches to study and enhance the success of organ repopulation strategies creating new grafts/organs for transplantation.

    Taiwan has a high prevalence of hepatitis B and C viral infections, and consequently a high burden of chronic liver diseases. Liver transplantation (LT) began in Taiwan in 1984, and living donor liver transplantation (LDLT) in 1994. Education and collaboration between physicians on a national and international scale were important factors in the development of transplantation in East Asia. Technical innovations in donor hepatectomy, vascular and biliary reconstruction, and interventional radiology, perioperative management of transplant patients and development of associated specialties have enabled achievement of excellent results after both adult and pediatric LDLT. The establishment of rigorous protocols to withstand strict medico-legal scrutiny, combined with technical excellence has contributed to excellent surgical outcomes. The socioeconomic development of Taiwan and the first nationwide hepatitis B vaccination program in the world have also contributed to the decrease in disease burden and improvement of quality of healthcare. This article examines the factors enabling the development of LT in Taiwan, the innovations that have contributed to excellent outcomes, and indicates the future prospects of LDLT in Taiwan.

    We reviewed the history, volume, outcomes, uniqueness, and challenges of living donor liver transplantation (LDLT) in Latin America. We used the data from the Latin American and Caribbean Transplant Society, local transplant societies, and opinions from local transplant experts. There are more than 160 active liver transplant teams in Latin America, but only 30 centers have used LDLT in the past 2 years. In 2014, 226 LDLTs were done in the region (8.5% of liver transplant activities). Living donor liver transplantation is mainly restricted to pediatric patients. Adult-to-adult LDLT activities decreased after the implementation of the model for end-stage liver disease score and a concomitant increase on the rate of deceased donors per million population. Posttransplant outcome analysis is not mandatory, transparent or regulated in most countries. More experienced teams have outcomes comparable to international expert centers, but donor and recipient morbidity might be underreported. Latin America lags behind in terms of the number of adult LDLT and the rate of living donor utilization in comparison with other continents with similar donation rates. Local alliances and collaborations with major transplant centers in the developed world will contribute to the development of LDLT in Latin America. PMID:27203583

These recommendations were developed from experts in the field from around the world. The authors conducted an analysis of the National Library of Medicine indexed literature on "living donor liver transplantation" [Medline search] using Grading of Recommendations Assessment, Development and Evaluation methodology. Writing was guided by the ILTS Policy on the Development and Use of Practice Guidelines (www.ilts.org). ILTS members, and many more nonmembers, were invited to comment. Recommendations have been based on information available at the time of final submission (March 2016). The lack of randomized controlled trials in this field to date is acknowledged and is reflected in the grading of evidence. Intended for use by physicians, these recommendations support specific approaches to the diagnostic, therapeutic, and preventive aspects of care. PMID:27120453

    Chronic hepatitis C virus (HCV) infection is the leading cause of liver transplantation in adults. Although the recurrence of HCV infection after liver transplantation is nearly universal, the recent advances in direct-acting antiviral (DAA) agents have revolutionized the management of HCV infection in the posttransplant setting. A number of these agents have been evaluated in recent clinical trials and have shown high sustained virologic response rates, shorter durations of treatment, and decreased adverse events when compared with the previous treatment of pegylated interferon and ribavirin. This article will review the current literature on the efficacy, tolerability, and potential drug interactions of various DAA agents in patients with recurrent HCV infection posttransplant.

    Over the sixteen year history of liver transplantation (LT) at Mayo Clinic in Jacksonville, Florida (MCF), we have maintained a practice devoted to excellence in pre- and post-LT management for patients suffering from end stage liver disease. With an emphasis on quality, MCF has made several adjustments with the goal of better utilizing marginal grafts for both successful post-transplant outcomes and minimizing waitlist mortality. This systematic approach is most exemplified in our experience with donation after cardiac death (DCD) liver allografts. Understanding the events during procurement has been critical to reducing the complications associated with donor warm ischemia time that are unique to DCD allografts. Better matching of donors to recipients has helped identify patients who are safe to receive more marginal grafts with successful patient and graft survival. Recognizing the spectrum of degree of sickness in patients undergoing LT, we implemented a multidisciplinary approach that allows for the avoidance of the intensive care unit after LT. In these ways, MCF continues to distinguish itself as an innovator in the field of transplantation for the benefit of continued better care for our patients suffering from end stage liver disease.

    AIM: To determine risk factors for early neurologic complications (NCs) after liver transplantation from perspective of recipient, donor, and surgeon. METHODS: In all, 295 adult recipients were enrolled consecutively between August 2001 and February 2014 from a single medical center in Taiwan. Any NC in the first 30 d post-liver transplantation, and perioperative variables from multiple perspectives were collected and analyzed. The main outcome was a 30-d NC. Generalized additive models were used to detect the non-linear effect of continuous variables on outcome, and to determine cut-off values for categorizing risk. Risk factors were identified using multiple logistic regression analysis. RESULTS: In all, 288 recipients were included, of whom 142 (49.3%) experienced at least one NC, with encephalopathy being the most common 106 (73%). NCs prolonged hospital stay (35.15 ± 43.80 d vs 20.88 ± 13.58 d, P < 0.001). Liver recipients’ age < 29 or ≥ 60 years, body mass index < 21.6 or > 27.6 kg/m2, Child-Pugh class C, history of preoperative hepatoencephalopathy or mental disorders, day 7 tacrolimus level > 8.9 ng/mL, and postoperative intra-abdominal infection were more likely associated with NCs. Novel risk factors for NCs were donor age < 22 or ≥ 40 years, male-to-male gender matching, graft-recipient weight ratio 0.9%-1.9%, and sequence of transplantation between 31 and 174. CONCLUSION: NCs post- liver transplantation occurs because of factors related to recipient, donor, and surgeon. Our results provide a basis of risk stratification for surgeon to minimize neurotoxic factors during transplantation. PMID:27350733

    Under the United Network for Organ Sharing (UNOS) policy, deceased donor livers may be offered to ABO-nonidentical candidates at each given Model for End-Stage Liver Disease (MELD) score and to blood type B candidates at MELD ≥30. To evaluate ABO-nonidentical liver transplantation (LT) in the United States, we examined all adult LT non-status 1 candidates, recipients and deceased liver donors from 2013 to 2015. There were 34 920 LT candidates (47% type O, 38% type A, 12% type B, 3% type AB) and 10 479 deceased liver donors (47% type O, 38% type A, 12% type B, 3% type AB). ABO-nonidentical LT occurred in 2%, 3%, 20% and 36% of types O, A, B and AB recipients, respectively, which led to a net liver loss of 6% for type O and 2% for type A recipients but a net liver gain of 14% for type B and 55% for type AB recipients. The LT MELD scores of ABO-identical versus -nonidentical recipients were 29 versus 34 for type O, 29 versus 19 for type A, 25 versus 38 for type B, and 22 versus 28 for type AB (p < 0.01). ABO-nonidentical LT increased liver supply for candidates with blood types B and AB but decreased supply for type O and A candidates. We urge refinement of UNOS policy surrounding ABO-nonidentical LT. PMID:26932134

    Liver transplant (LT) is a major surgical undertaking involving major fluid shifts, hemodynamic instability and metabolic derangements in a patient with preexisting liver failure and multisystemic derangements. Monitoring and organ support initiated in the preoperative phase is continued intraoperatively and into the postoperative phase to ensure an optimal outcome. As cardiovascular events are the leading cause of non-graft related death among LT recipients, major emphasis is placed on cardiovascular monitoring. The other essential monitoring are the continuous assessment of coagulapathy, extent of metabolic derangements, dyselectrolytemis and intracranial pressure monitoring in patients with fulminant hepatic failure. The type and extent of monitoring differs with need according to preexisting child status of the patient and the extent of systemic derangements. It also varies among transplant centers and is mainly determined by individual or institutional practices. PMID:25755443

    Liver transplantation (LT) is a stressful condition for the cardiovascular system of patients with advanced hepatic disease. The underlying hemodynamic and cardiac status of patients with cirrhosis is crucial to determine which patients should became recipients. In addition to advanced age and the presence of comorbidities, there are specific cardiovascular responses in cirrhosis that can be detrimental to the LT candidate. Patients with cirrhosis requiring LT usually demonstrate increased cardiac output, a compromised ventricular response to stress, low systemic vascular resistance and bradycardia. Post-transplant reperfusion may result in cardiac death due to a multitude of causes, including arrhythmia, acute heart failure and myocardial infarction. This review examines screening strategies for transplant candidates and details the prognostic value of common test used to identify ischemic heart disease, heart failure, portopulmonary hypertension. There are discused evidence-based recommendations for their evaluation and management. PMID:22844825

    The ultimate goal of treatment is suppression of viral replication to undetectable HBV-DNA levels prior to and after liver transplantation (LT) to prevent infection of the newly transplanted liver. Most published data are available from therapy with lamivudine (LAM) in pre- and post-transplant HBV patients. Add-on therapy with adefovir dipivoxil (ADV) in pre-transplant LAM-resistant patients has been shown to represent an effective antiviral strategy leading to hepatic recompensation in many cases and, eventually, removal from the waiting list. Newer nucleos(t)ide analogues such as entecavir, tenofovir and telbivudine have shown lower resistance rates than LAM and more antiviral potency in studies in the non-transplant setting. Combined hepatitis B immune globulin (HBIG) and nucleos(t)ide analogue therapy have been widely adopted as the most effective treatment strategy against recurrent HBV disease after LT. Many programs have evaluated lower doses or a shorter duration of HBIG and intramuscular versus intravenous routes of administration. Active immunisation using recombinant HBV vaccines, including the S, pre-S1 and pre-S2 regions, and those with immunostimulatory adjuvants, seem to be more immunogenic than the currently available vaccines and have been used in studies to replace HBIG. Furthermore, it has been shown that immune memory against HBV can be adoptively transferred from organ donors to transplant recipients. Nucleos(t)ide analogue combination therapies might provide an alternative to the current treatment paradigm with costly HBIG; however, experience with this new treatment regimen is very limited and controlled clinical studies are urgently warranted to investigate its safety and efficacy and to determine which nucleos(t)ide analogue combinations will be the most promising in the long term after LT.

  11. Transfusion and coagulation management in liver transplantation.

    PubMed

    2014-05-28

    There is wide variation in the management of coagulation and blood transfusion practice in liver transplantation. The use of blood products intraoperatively is declining and transfusion free transplantations take place ever more frequently. Allogenic blood products have been shown to increase morbidity and mortality. Primary haemostasis, coagulation and fibrinolysis are altered by liver disease. This, combined with intraoperative disturbances of coagulation, increases the risk of bleeding. Meanwhile, the rebalancing of coagulation homeostasis can put patients at risk of hypercoagulability and thrombosis. The application of the principles of patient blood management to transplantation can reduce the risk of transfusion. This includes: preoperative recognition and treatment of anaemia, reduction of perioperative blood loss and the use of restrictive haemoglobin based transfusion triggers. The use of point of care coagulation monitoring using whole blood viscoelastic testing provides a picture of the complete coagulation process by which to guide and direct coagulation management. Pharmacological methods to reduce blood loss include the use of anti-fibrinolytic drugs to reduce fibrinolysis, and rarely, the use of recombinant factor VIIa. Factor concentrates are increasingly used; fibrinogen concentrates to improve clot strength and stability, and prothrombin complex concentrates to improve thrombin generation. Non-pharmacological methods to reduce blood loss include surgical utilisation of the piggyback technique and maintenance of a low central venous pressure. The use of intraoperative cell salvage and normovolaemic haemodilution reduces allogenic blood transfusion. Further research into methods of decreasing blood loss and alternatives to blood transfusion remains necessary to continue to improve outcomes after transplantation. PMID:24876736

Because the liver acts as an innate immunity-dominant organ, there are immunological differences between the liver and other organs. The specific features of hepatic natural killer (NK), NKT and Kupffer cells and their role in the mechanism of liver transplant rejection, tolerance and hepatic ischemia-reperfusion injury are discussed in this review.

    Improvements in surgical techniques, immunosuppression, and post-transplantation patient care have led to the optimization of liver transplantation outcomes. However, the waiting list for liver transplantation is increasing at a greater pace. The large gap between the growing pool of patients waiting for liver transplantation and the scarcity of donor organs has fueled efforts to maximize existing donors and identify new sources. This article will be focused on the current state of liver transplantation using grafts from extended criteria donors (elderly donors, steatotic donors, donors with malignancies, donors with viral hepatitis) and from donation after cardiac death (DCD), as well as the use of partial grafts (split grafts and living-donor liver transplantation) and other suboptimal donors (donors with hypernatremia, infections, hypotension and inotropic support). Overall, broadened criteria for acceptable donor livers appear to lessen graft survival rates somewhat compared with rates for standard criteria organs. PMID:25013654

    Liver transplantation is the only definitive treatment option for patients with irrevocable acute or chronic liver failure. In the last four decades, liver transplantation has developed from an experimental approach with a very high mortality to an almost routine procedure with good short- and long-term survival rates. Here, we present an up-to-date overview of the indications and contraindications for liver transplantation. It is shown how the evaluation of a candidate and finally listing for transplantation has to be performed in a multidisciplinary setting. Meticulous listing, timing, and organ allocation are the crucial factors to achieve an optimal outcome for the individual patient on the one hand, and reasonably using the limited deceased donor pool on the other hand. Living-donor liver transplantation is demanding but necessarily increasing. Because patients after liver transplantation need lifelong aftercare, it is important for primary care clinicians to understand the basic medical problems and risks. PMID:24789874

    Various types of extracorporeal membrane oxygenation methods have been used in liver transplant operations. The main indications are portopulmonary or hepatopulmonary syndromes and other cardiorespiratory failure syndromes that are refractory to conventional therapy. There is little literature available about extracorporeal membrane oxygenation, especially after liver transplant. We describe our experience with 2 patients who had living-related liver transplant. A 69-year-old woman had refractory aspergillosis pneumonia and underwent pumpless extracorporeal lung assist therapy 4 weeks after liver transplant. An 8-month-old boy with biliary atresia underwent urgent liver transplant; he received venoarterial extracorporeal membrane oxygenation therapy on postoperative day 1. Despite our unsuccessful experience with 2 patients, extracorporeal membrane oxygenation and pumpless extracorporeal lung assist therapy for liver transplant patients may improve prognosis in selected cases.

    Since the first successful liver transplantation by Starzl et al. in 1967, liver transplantation has become the standard therapy for many liver diseases, mainly chronic liver disease. Most liver transplantations performed in Europe and North America utilize deceased donors while a considerable portion of organ requirements is supplied by living donors in Asian countries including Turkey. The actual history of solid organ transplantation in Turkey began with the pioneering work of Dr. Haberal in collaboration with Thomaz E. Starzl in 1974 in Colorado University at Denver. The first successful solid organ transplantation in Turkey was accomplished by Haberal in 1975 with a living donor renal transplantation. Subsequently, legislations no 2238 and 2594 dated 1979 and 1982, respectively, were passed, paving the way for cadaveric tissue/organ utilization and preservation in Turkey. The first deceased donor liver transplantation and the first living donor liver transplantation were performed in 1988 and 1990, respectively. There are currently 45 liver transplantation centers in Turkey. Of these, 25 are state universities, 8 are private (foundation) universities, 9 are private hospitals, and 3 are training and research hospitals belonging to the Ministry of Health. A total of 7152 liver transplantations were performed in Turkey between January 2002 and May 2014. Of these, 4848 (67.8%) used living donors and 2304 (32.2%) used deceased donors. These figures indicate that, despite widespread organ donation campaigns and media-sponsored propaganda, desired targets have not been met yet in providing deceased organ donation. Despite unsatisfactory levels attained in supplying deceased donors, both the number of annual liver transplantations and improvements in overall survival rates of organ transplanted patients continues to increase. Actually, the one-year patient survival rate after liver transplantation in 2013 was 80.5%. This rate is getting better with each passing year

  17. Future Economics of Liver Transplantation: A 20-Year Cost Modeling Forecast and the Prospect of Bioengineering Autologous Liver Grafts

    During the past 20 years liver transplantation has become the definitive treatment for most severe types of liver failure and hepatocellular carcinoma, in both children and adults. In the U.S., roughly 16,000 individuals are on the liver transplant waiting list. Only 38% of them will receive a transplant due to the organ shortage. This paper explores another option: bioengineering an autologous liver graft. We developed a 20-year model projecting future demand for liver transplants, along with costs based on current technology. We compared these cost projections against projected costs to bioengineer autologous liver grafts. The model was divided into: 1) the epidemiology model forecasting the number of wait-listed patients, operated patients and postoperative patients; and 2) the treatment model forecasting costs (pre-transplant-related costs; transplant (admission)-related costs; and 10-year post-transplant-related costs) during the simulation period. The patient population was categorized using the Model for End-Stage Liver Disease score. The number of patients on the waiting list was projected to increase 23% over 20 years while the weighted average treatment costs in the pre-liver transplantation phase were forecast to increase 83% in Year 20. Projected demand for livers will increase 10% in 10 years and 23% in 20 years. Total costs of liver transplantation are forecast to increase 33% in 10 years and 81% in 20 years. By comparison, the projected cost to bioengineer autologous liver grafts is $9.7M based on current catalog prices for iPS-derived liver cells. The model projects a persistent increase in need and cost of donor livers over the next 20 years that’s constrained by a limited supply of donor livers. The number of patients who die while on the waiting list will reflect this ever-growing disparity. Currently, bioengineering autologous liver grafts is cost prohibitive. However, costs will decline rapidly with the introduction of new manufacturing

    Background/Aims: Liver transplantation (LT) is a life-saving intervention for patients with liver failure. LT recipients' adherence to their therapeutic regimen is an essential element for graft survival. According to WHO, the impact of medication non-adherence in solid organ transplantation has shown to cost $15–100 million annually. The aim of the present study was to identify the factors that best predict medication adherence and to explore the relationship between treatment satisfaction and medication adherence in liver transplant recipients. Patients and Methods: Adult liver transplant patients at King Abdulaziz Medical City were included in the study. Patients completed the 8-item Morisky Medication Adherence Scale (MMAS-8) and the Treatment Satisfaction Questionnaire for Medication (TSQM 1.4) in addition to several socio-demographic and transplant-related data. Results: A total of 154 patients were included in the study and of these 59.7% were adherent. Older age was a significant predictor of adherence (P < 0.05). The mean treatment satisfaction score was 91.9 ± 12.7 in Effectiveness, 80.0 ± 25.9 in Side Effects, 83.5 ± 15.7 in Convenience, and 94.6 ± 8.6 in Global Satisfaction. Further analysis indicated that patients in the adherent group had reported significantly higher satisfaction scores than those in the non-adherent group (P < 0.05) in all treatment satisfaction domains: Effectiveness (94.4 ± 10.4 vs. 88.6 ± 14.8), Side Effects (83.9 ± 22.0 vs. 74.2 ± 30.1), Convenience (87.0 ± 13.9 vs. 77.2 ± 16.1), and Global Satisfaction (96.9 ± 6.6 vs. 91.2 ± 8.6). Conclusion: Older patients and those who were more satisfied with their treatment tend to have better adherence to the prescribed medications. Therefore, increasing patients' satisfaction with their treatment should be an integral element of future care plans designed to improve treatment outcomes in liver transplant recipients.

    BACKGROUND The model of end-stage liver disease (MELD) score is currently used for donor liver allocation in many regions. The objective of this retrospective study was to assess the MELD score and its diverse variants as prognostic models for mortality after liver transplantation. MATERIAL AND METHODS An analysis of 454 consecutive adult liver transplants since the introduction of MELD-based donor liver allocation was conducted. Eight different MELD score variants were investigated. Receiver operating characteristic (ROC) curve analysis was performed to calculate the sensitivity, specificity, and overall model correctness of the investigated scores as a predictive model. The Brier score was used for the prediction of model accuracy and calculated as described before. Study endpoints were 90-day mortality and long-term patient mortality. RESULTS A 90-day mortality of 15.4% (n=69) and long-term mortality of 25% (n=112) were observed. All investigated models fail to reach relevant areas under the ROC curve greater than 0.700 for the prediction of mortality after liver transplantation. All calculated Brier scores were greater than 0.25, indicating a significant lack of model discrimination and calibration of the investigated scores. CONCLUSIONS A prognostic model for the prediction of outcome after transplantation still needs to be identified and should allow weighing urgency against utility in liver transplantation.

    Porphyrias are a group of eight metabolic disorders, each resulting from a mutation that affects an enzyme of the heme biosynthetic pathway. Porphyrias are classified as hepatic or erythropoietic, depending upon the site where the gene defect is predominantly expressed. Clinical phenotypes are classified as follows: (1) acute porphyrias with neurovisceral symptoms: acute intermittent porphyria; delta amino-levulinic acid hydratase deficiency porphyria; hereditary coproporphyria; and variegate porphyria and (2) cutaneous porphyrias with skin blistering and photosensitivity: porphyria cutanea tarda; congenital erythropoietic porphyria; hepatoerythropoietic porphyria and both erythropoietic protoporphyrias: autosomal dominant and X-linked. Liver transplantation (LT) may be needed for recurrent and/or life-threatening acute attack in acute intermittent porphyria or acute liver failure or end-stage chronic liver disease in erythropoietic protoporphyria. LT in acute intermittent porphyria is curative. Erythropoietic protoporphyria patients needing LT should be considered for bone marrow transplantation to achieve cure. Conclusion This article provides an overview of porphyria with diagnostic approaches and management strategies for specific porphyrias and recommendations for LT with indications, pretransplant evaluation, and posttransplant management.

    A new Organ Procurement and Transplantation Network/United Network for Organ Sharing bylaw recommends that all centers appoint a director of liver transplant anesthesia with a uniform set of criteria. We obtained survey data from the Liver Transplant Anesthesia Consortium so that we could compare existing criteria for a director in the United States with the current recommendations. The data set included responses from adult academic liver transplant programs before the new bylaw. The respondent rates were within statistical limits to exclude sampling bias. All centers had a director of liver transplant anesthesia. The criteria varied between institutions, and the data suggest that the availability of resources influenced the choice of criteria. The information suggests that the criteria used in the new bylaw reflect existing practices. The bylaw plays an important role in supporting emerging leadership roles in liver transplant anesthesia and brings greater uniformity to the directorship position. PMID:23447113

    In 1967, Starzl et al performed the first successful liver transplantation for a patient diagnosed with hepatoblastoma. In the following, liver transplantation was considered ideal for complete tumor resection and potential cure from primary hepatic malignancies. Several reports of liver transplantation for primary and metastatic liver cancer however showed disappointing results and the strategy was soon dismissed. In 1996, Mazzaferro et al introduced the Milan criteria, offering liver transplantation to patients diagnosed with limited hepatocellular carcinoma. Since then, liver transplantation for malignant disease is an ongoing subject of preclinical and clinical research. In this context, several aspects must be considered: (1) Given the shortage of deceased-donor organs, long-term overall and disease free survival should be comparable with results obtained in patients transplanted for non-malignant disease; (2) In this regard, living-donor liver transplantation may in selected patients help to solve the ethical dilemma of optimal individual patient treatment vs organ allocation justice; and (3) Ongoing research focusing on perioperative therapy and anti-proliferative immunosuppressive regimens may further reduce tumor recurrence in patients transplanted for malignant disease and thus improve overall survival. The present review gives an overview of current indications and future perspectives of liver transplantation for malignant disease. PMID:24833863

    2014-09-01

    The transjugular intrahepatic portosystemic shunt (TIPS) has long been referred to as a procedure performed as "a bridge to transplantation" since, like many other portosystemic shunts, it decompresses the portal circulation and stabilizes patients but does not definitively treat portal hypertension. One of the major advantages of TIPS over surgically placed portosystemic shunts in the transplant era is that the TIPS is intrahepatic and is removed in situ with the native liver, and usually does not need additional surgery (unlike takedown/ligation of surgical shunts). There are several studies that evaluate TIPS before transplantation-not as a bridge/temporizing measure, but as a prelude to the transplant to decompress the portal circulation and reduce portosystemic engorgement and collaterals and thus, in theory, reduce intraoperative bleeding during liver transplantation. However, these studies, mostly in the transplant literature, have been equivocal from an intraoperative and posttransplant clinical outcome standpoint. TIPS creation in liver transplant recipients is another interesting aspect of TIPS. There has been a debate about whether or not liver transplantation adds additional technical difficulty to the TIPS procedure. Initially, many theories were proposed as to the technical difficulty of TIPS in a transplanted liver. However, recent opinions and published studies demonstrate that whole-graft liver transplantation does not pose a significant technical difficulty to TIPS. Moreover, there are several recent studies evaluating the outcomes of TIPS in liver transplant recipients, showing that outcomes are less favorable when compared with TIPS in nontransplanted patients. This article discusses the results of TIPS as a preoperative prelude to liver transplantation. In addition, it discusses the technical and clinical outcomes of TIPS in liver transplant recipients.

    Metabolic syndrome (MS) is an established risk factor for atherosclerosis and cardiovascular disease that affects 20-30% of the adult population in the western world, correlating with increased incidence of cardiovascular disease. Survival following liver transplantation (LT) has been steadily improving over the last 2 decades, with graft loss becoming a relatively rare cause of morbidity and mortality post LT. The improvement in short-term survival following LT has resulted in an increased incidence of metabolic and cardiovascular complications, which affect the mid- and long term survival. Patients following LT typically gain weight and might develop diabetes, hypertension and dyslipidemia as a consequence of their immunosuppressive therapy and their lifestyle. In this paper we review the prevalence of metabolic and cardiovascular complications following LT, their impact on post-transplant morbidity and mortality and their optimal management. PMID:25830307

    To date, the course of cognitive development in children after liver transplantation (Ltx) is poorly understood. Cognitive performance, however, is crucial in all developmental stages and for educational achievement. This cross-sectional single-center study examined the prevalence of long-term cognitive impairment in a cohort of 64 pediatric patients after Ltx. Median age at Ltx was 12 months. The revised Wechsler Intelligence Scale IV was administered to assess cognitive performance. Patients were compared with an age- and gender-matched group of children without a chronic health condition. Liver transplanted children performed significantly worse in three of four cognitive domains as well as in the Total Intelligence Quotient (Total IQ) (p = 0.017 to p = 0.005). Liver transplant recipients showed substantially more "serious delays" (IQ < 70) compared to the reference group (9.4% vs. 4.7%). Children with a genetic-metabolic disease performed worse than the other groups in three of the four WISC Indices and in the Total IQ (p = 0.05 to p = 0.01). The strongest association was revealed between height at Ltx and Verbal Comprehension (R(2)  = 0.21), Perceptual Reasoning (R(2)  = 0.30), Working Memory (R(2)  = 0.23) and Total IQ (R(2)  = 0.25). Our results indicate a high impact of primary diagnosis and height percentile at Ltx even on children's long-term cognitive performance. PMID:24102763

    Background Liver transplantation is performed at large transplant centers worldwide as a therapeutic intervention for patients with end-stage liver diseases. Aim To analyze the outcomes and incidence of liver transplantation performed at the University of São Paulo and to compare those with the State of São Paulo before and after adoption of the Model for End-Stage Liver Disease (MELD) score. Method Evaluation of the number of liver transplantations before and after adoption of the MELD score. Mean values and standard deviations were used to analyze normally distributed variables. The incidence results were compared with those of the State of São Paulo. Results There was a high prevalence of male patients, with a predominance of middle-aged. The main indication for liver transplantation was hepatitis C cirrhosis. The mean and median survival rates and overall survival over ten and five years were similar between the groups (p>0.05). The MELD score increased over the course of the study period for patients who underwent liver transplantation (p>0.05). There were an increased number of liver transplants after adoption of the MELD score at this institution and in the State of São Paulo (p<0.001). Conclusion The adoption of the MELD score led to increase the number of liver transplants performed in São Paulo. PMID:25184772

    Optimised home parenteral nutrition is still, after 35 years of progress, the "gold standard "for benign but chronic intestinal failure. better recognition of chronic intestinal failure, in its multiple facets, is needed to improve Home Parenteral Nutrition by adding associated treatments such as intestinal trophic factors, rehabilitative surgery (reestablishment of colonic continuity, reverse jejunal segment in severe short gut type II) and/or reconstructive surgery (intestinal transplantation for end-stage intestinal failure). Intestinal transplantation is now a mature therapy with formal indications, especially in case of failure of Home Parenteral Nutrition (mainly Home Parenteral Nutrition-associated severe liver disease), where combined Liver-intestine transplantation is indicated before end-stage liver failure occurs. For high-risk patients, 'preemptive' intestinal transplantation alone should be discussed before home parenteral nutrition-related complications occur. Even, if the results in terms of patient survival have improved over the past 20 years, the 5-year survival rate still does not exceed 50%. Thus, each case should be discussed in a dedicated tertiary center. The ESPEN Home Artificial Nutrition Working Group conducted a survey in 2004 to assess potential candidates for intestinal transplantation in France, among the adult population of patients with home parenteral nutrition. The prevalence of potential candidates for intestinal transplantation was estimated at about 20% (about 40 new adult cases per year). Even though surgical techniques for isolated intestine, liver-intestine, and multivisceral transplantation were developed in the 1960s, very few patients were transplanted before 1990, because of inadequate initial immunosuppressive regimens. most patients died within days or months after Intestine transplantation. The discouraging results of the first clinical trials were due to technical complications, sepsis, and the failure of conventional

    Avoiding the limitations of the adult liver niche, transplantation of hepatic stem/progenitor cells into fetal liver is desirable to analyze immature cells in a hepatic developmental environment. Here, we established a new monitor tool for cell fate of hepatic progenitor cells transplanted into the mouse fetal liver by using ex utero surgery. When embryonic day (ED) 14.5 hepatoblasts were injected into the ED14.5 fetal liver, the transplanted cells expressed albumin abundantly or {alpha}-fetoprotein weakly, and contained glycogen in the neonatal liver, indicating that transplanted hepatoblasts can proliferate and differentiate in concord with surrounding recipient parenchymal cells. The transplanted cells became mature in the liver of 6-week-old mice. Furthermore, this method was applicable to transplantation of hepatoblast-like cells derived from mouse embryonic stem cells. These data indicate that this unique technique will provide a new in vivo experimental system for studying cell fate of hepatic stem/progenitor cells and liver organogenesis.

    Recognition of acute-on-chronic liver failure (ACLF) as a unique entity is slowly evolving, as are therapies to improve survival of affected patients. Further investigation into its disease process and proper treatments with critical timing are important for improving patient survival. At this time, liver transplant is the only treatment known to improve survival in liver-failure patients. However, liver transplantation has its own disadvantages, such as organ shortage and the need for lifelong immunotherapy. Bridging therapies such as extracorporeal liver-support systems are attractive options to stabilize patients until transplantation or spontaneous recovery. The goals of these liver-support systems are to remove detoxification products, reduce systemic inflammation, and enhance regeneration of the injured liver. These devices have been under development for the past decade; a few are in clinical trials. At this time, there is no proven clearcut survival benefit in these devices, but they may improve the outcome of challenging cases and potentially avoid or postpone liver transplantation in some cases.

    In this case report we present in detail the complex nature of enteral feeding, diarrhea, hypoalbuminemia, and edema in a critically ill patient. We also discuss the use of a peptide-elemental formula in this patient, who suffered continuous diarrhea for 15 weeks after liver transplantation. Use of this formula was associated with cessation of the diarrhea and permitted adequate nutritional delivery. After 26 weeks of mechanical pulmonary ventilation, extubation was possible. This case illustrates the ineffectiveness of parenteral albumin infusions for treatment of enteral edema and demonstrates the restoration of normal intestinal absorptive capacity when ultrafiltration was instituted and the patient's generalized edematous state was corrected.

    Liver transplantation is one of the most spectacular of surgical achievements. It is a demanding and expensive procedure, requiring great surgical skill and a great depth of supporting services. Precisely because it is a procedure at the leading edge of medicine, more and more units in developed countries are pressing to be allowed to carry it out. But there are many moral and ethical problems, some of which can be usefully examined using a “Mozart model” as proposed by Starzl. PMID:2282327

    We present the case of a 48-year-old otherwise healthy man who required an urgent liver transplant owing to acute liver failure after flupirtine treatment. After 3 months of daily flupirtine intake as treatment for pseudoradicular pain syndrome, he presented at our institution with signs of jaundice and hepatic encephalopathy. Laboratory results showed elevated liver transaminases, and the liver histopathology supported the assumed drug-induced liver injury. After listing him for an urgent liver transplant, he was given a liver graft from a 21-year-old man. Despite a rejection episode on day 11 after the surgery (which was successfully treated by steroid pulse therapy), the postoperative course was uneventful and the patient recovered completely. To the best of our knowledge, this is the first report of a liver transplant for acute liver failure after taking flupirtine. PMID:21819373

    Alcoholic liver disease is an established, yet controversial, indication for liver transplantation. Although an abstinence period of up to 6 mo prior to transplantation is mandatory, alcohol relapse after transplantation is a common event. In case of recurrence of heavy drinking, graft survival is significantly impaired. Guidelines on detection and surveillance of alcohol consumption in this patient cohort are lacking. This review summarizes the challenge of patient selection as well as the current knowledge on established and novel alcohol biomarkers with special focus on liver transplant candidates and recipients.

    Sinusoidal obstruction syndrome (SOS), previously known as hepatic veno-occlusive disease, is a rare disorder in solid organ transplant patients, and is an uncommon complication after liver transplantation. Severe SOS with hepatic failure causes considerable mortality. Tacrolimus has been reported to be an offending agent, which potentially plays a role in the pathophysiological process of SOS. SOS due to tacrolimus has been reported in lung and pancreatic transplantations, but has never been described in a liver transplant recipient. Herein, we present a case of SOS after liver transplantation, which was possibly related to tacrolimus. A 27-year-old man developed typical symptoms of SOS with painful hepatomegaly, ascites and jaundice after liver transplantation, which regressed following withdrawal of tacrolimus. By excluding other possible predisposing factors, we concluded that tacrolimus was the most likely cause of SOS. PMID:26034381

    Introduction This multicentre randomised controlled clinical trial will aim to determine the ability of an extract (TJ-100) of Daikenchuto (traditional Japanese herbal medicine; Kampo) to prevent bowel dysfunction in at least 110 patients after liver transplantation (LT). Methods and analysis The following co-primary end points will be evaluated on postoperative day 7: total oral and enteral caloric intake, abdominal distension and abdominal pain. The secondary end points will comprise sequential changes of total oral and enteral caloric intake after LT, sequential changes in numeric rating scales for abdominal distension and pain, elapsed time to the first postoperative passage of stool, quality of life assessment using the Gastrointestinal Symptom Rating Scale score (Japanese version), postoperative liver function, liver regeneration rate, incidence of bacteraemia and bacterial strain, trough level of immunosuppressants, occurrence of acute cellular rejection, discharge or not within 2 months after LT, sequential changes of portal venous flow to the graft and ascites discharge. The two arms of the study will comprise 55 patients per arm. Ethics and dissemination The study has been conducted according to the CONSORT statement. All participants signed a written consent form, and the study has been approved by the institutional review board of each participating institute and conducted in accordance with the Declaration of Helsinki of 1996. The findings will be disseminated through scientific and professional conferences, and in peer-reviewed journals. Trial registration number The DKB 14 Study was registered in the University Hospital Medical Information Network Clinical Trial Registration (UMIN-CTR), Japan (registration number: UMIN000014326) during 2014.

    Nonalcoholic steatohepatitis (NASH) is the hepatic manifestation of obesity and insulin resistance. The aim of this study was to determine the frequency of NASH as an indication for liver transplantation (LT) in children and young adults and to characterize patient and graft survival. The study included all children and young adult patients (up to the age of 40 years) who underwent LT in the United States for NASH cirrhosis from the 1987 to 2012 United Network for Organ Sharing (UNOS) database. Kaplan-Meier analysis was used to assess patient and graft survival. A total of 330 patients were included, 68% were Caucasian, and the mean BMI was 33.6 ± 6.3. Age at time of LT ranged between 4 and 40 years (mean 33.9 ± 6.6 years). Fourteen subjects were <18 years of age at time of LT and 20 were between the ages of 18 and 25 years. Median follow-up after 1st LT was 45.8 months [10.7, 97.3]. During this time, 30% of subjects (n = 100) died and 11.5% (n = 38) were retransplanted including 13 for NASH recurrence. In conclusion, NASH can progress to end-stage liver disease requiring LT in childhood and early adulthood. A significant number of young patients transplanted for NASH cirrhosis required retransplantation. PMID:26402655

  1. Reducing transfusion requirements in liver transplantation

    Liver transplantation (LT) was historically associated with massive blood loss and transfusion. Over the past two decades transfusion requirements have reduced dramatically and increasingly transfusion-free transplantation is a reality. Both bleeding and transfusion are associated with adverse outcomes in LT. Minimising bleeding and reducing unnecessary transfusions are therefore key goals in the perioperative period. As the understanding of the causes of bleeding has evolved so too have techniques to minimize or reduce the impact of blood loss. Surgical “piggyback” techniques, anaesthetic low central venous pressure and haemodilution strategies and the use of autologous cell salvage, point of care monitoring and targeted correction of coagulopathy, particularly through use of factor concentrates, have all contributed to declining reliance on allogenic blood products. Pre-emptive management of preoperative anaemia and adoption of more restrictive transfusion thresholds is increasingly common as patient blood management (PBM) gains momentum. Despite progress, increasing use of marginal grafts and transplantation of sicker recipients will continue to present new challenges in bleeding and transfusion management. Variation in practice across different centres and within the literature demonstrates the current lack of clear transfusion guidance. In this article we summarise the causes and predictors of bleeding and present the evidence for a variety of PBM strategies in LT. PMID:26722645

    Previous case series have reported serious complications of chicken pox (CP) after pediatric liver transplantation (PLT), mainly due to visceral dissemination. The goal of our study was to determine the incidence, risk factors, and outcomes of CP after PLT. A case-control study of all CP infections in pediatric transplant recipients followed at our center from September 1993 to April 2004 was performed. Data were collected before and after infection and at the same time points in age-, gender-, and transplant year-matched controls. Potential risk factors prior to CP and adverse outcomes after infection were compared between cases and controls. Twenty (6.2%) developed CP at a median of 1.8 yr (0.6-4.8) after PLT. All CP infections were cutaneous, with no evidence of organ involvement. Twelve were hospitalized: 9 only to receive intravenous acyclovir and 3 stayed > or =2 weeks for other complications. Risk factors were not statistically different among cases and controls. Of the outcomes analyzed, cases were significantly more likely to develop non-CP infections within one year of CP than controls (Hazard Ratio = 12.6, 95% confidence interval = 3.1-51.7; P < 0.001). These infections were often bacterial and occurred long after CP infection. In conclusion, CP is uncommon after PLT and has a low likelihood of organ dissemination. No risk factors were identified. Some cases required prolonged hospitalizations. Close monitoring for the development of late bacterial infections is warranted. PMID:16315312

    Liver transplantation has been associated with massive blood loss and considerable transfusion requirements. Bleeding in orthotopic liver transplantation is multifactorial. Technical difficulties inherent to this complex surgical procedure and pre operative derangements of the primary and secondary coagulation system are thought to be the principal causes of perioperative hemorrhage. Intraoperative practices such as massive fluid resuscitation and resulting hypothermia and hypocalcemia secondary to citrate toxicity further aggravate the preexisting coagulopathy and worsen the perioperative bleeding. Excessive blood loss and transfusion during orthotopic liver transplant are correlated with diminished graft survival and increased septic episodes and prolonged ICU stay. With improvements in surgical skills, anesthetic technique, graft preservation, use of intraoperative cell savers and overall perioperative management, orthotopic liver transplant is now associated with decreased intra operative blood losses. The purpose of this review is to discuss the risk factors predictive of increased intra operative bleeding in patients undergoing orthotopic liver transplant. PMID:26131330

    The large MRC/ECOG adult acute lymphoblastic leukemia (ALL) study establishes the value of sibling donor allogeneic transplant in standard-risk patients demonstrating superior outcome to conventional chemotherapy. The small but significant number of patients having matched unrelated donor (MUD) transplants on this study protocol appear to do well, and may establish the value of such an approach for those without a sibling. Reduced-intensity conditioning (RIC) conditioning might begin to address the transplant-related mortality problems of the older patients. The youngest adults may not need a transplant at all. If they are now treated on pediatric chemotherapy protocols, their outcome appears to improve significantly. The MRC/ECOG study, the emerging MUD and RIC data all help establish allogeneic transplant more widely in this disease. PMID:19147069

    National liver transplant volume has declined since 2006, in part due to worsening donor organ quality. Trends that degrade organ quality are expected to continue over the next two decades. We used the United Network for Organ Sharing (UNOS) database to inform a 20-year discrete event simulation estimating liver transplant volume from 2010 to 2030. Data to inform the model were obtained from deceased organ donors between 2000 and 2009. If donor liver utilization practices remain constant, utilization will fall from 78% to 44% by 2030, resulting in 2230 fewer liver transplants. If transplant centers increase their risk tolerance for marginal grafts, utilization would decrease to 48%. Institution of “opt-out” organ donation policies to increase the donor pool would still result in 1380-1866 fewer transplants. Ex-vivo perfusion techniques that increase the use of marginal donor livers may stabilize liver transplant volume. Otherwise, the number of liver transplants in the US will decrease substantially over the next 15 years. Conclusions The transplant community will need to accept inferior grafts and potentially worse post-transplant outcomes and/or develop new strategies for increasing organ donation and utilization in order to maintain the number of liver transplants at the current level.

    SUMMARY With improvements in patient and graft survival after liver transplantation, recipient quality of life (QOL) has become an important focus of patient care and clinical outcomes research. To provide a better understanding of the instruments used to assess QOL in the adult liver transplant population, we conducted a systematic review of the MEDLINE database and Cochrane library. Our review identified 128 relevant articles utilizing more than 50 different QOL instruments. Generic health status instruments are the most commonly used, and among them the Medical Outcomes Study Short Form-36 (SF-36), the Hospital Anxiety and Depression Scale (HADS), and the Beck Depression Inventory (BDI) are the most prevalent. Few studies (16%) included targeted, disease-specific instruments. The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) Quality of Life questionnaire, the Liver Disease Quality of Life questionnaire, and the Chronic Liver Disease questionnaire are the most frequently employed targeted instruments; however, these instruments have been designed to assess QOL in patients with chronic liver disease rather than patients after liver transplantation. The present review focuses on the psychometric properties of the existing QOL instruments and discusses their individual strengths and limitations in evaluating liver transplantation recipients. The lack of a gold-standard QOL instrument for liver transplant recipients is an impediment to cross-study comparisons. We conclude that the development of a QOL instrument specifically for liver transplant recipients will improve QOL assessment in this population leading to a more nuanced understanding of the factors that influence transplant recipients’ well-being.

    BACKGROUND In adult liver transplantation, arterial conduits have been associated with increased risk for vascular complications and inferior outcome. MATERIAL AND METHODS Complication rates and outcomes of adult patients undergoing liver transplantation in our center between 1990 and 2012 were analyzed retrospectively. Characteristics, transplantation-related factors, and survival rates of patients with conduit grafts (n=43) were compared to patients with a standard arterial anastomosis (n=904) by univariate and multivariate analysis. RESULTS Patients in the conduit group were younger but had a significantly higher proportion of high-urgency and re-transplantations. While patient survival was comparable between the groups, graft survival was inferior for patients with a conduit (1-year, 5-year, and 10-year survival, control vs. conduit group: 87.3%, 78.8% and 71.5% vs. 72.4%, 63.8%, and 41.8%, respectively, p=0.008). In univariate analysis, an arterial conduit was associated with more arterial and biliary complications. However, an arterial conduit was not an independent risk factor for graft or patient survival in a Cox regression analysis. CONCLUSIONS An arterial conduit is associated with more vascular complications, yet a conduit per se does not influence graft survival. The inferior outcome may reflect the complex situation of the sicker liver transplant patients needing a non-standard arterial anastomosis. PMID:27215293

    With less ischemia, improved donor selection and controlled procedures, living donor liver transplantation (LDLT) might lead to less HLA donor-specific antibody (DSA) formation or fewer adverse outcomes than deceased donor liver transplantation (DDLT). Using the multicenter A2ALL (Adult-to-Adult Living Donor Liver Transplantation Cohort Study) biorepository, we compared the incidence and outcomes of preformed and de novo DSAs between LDLT and DDLT. In total, 129 LDLT and 66 DDLT recipients were identified as having serial samples. The prevalence of preformed and de novo DSAs was not different between DDLT and LDLT recipients (p = 0.93). There was no association between patient survival and the timing (preformed vs. de novo), class (I vs. II) and relative levels of DSA between the groups; however, preformed DSA was associated with higher graft failure only in DDLT recipients (p = 0.01). De novo DSA was associated with graft failure regardless of liver transplant type (p = 0.005) but with rejection only in DDLT (p = 0.0001). On multivariate analysis, DSA was an independent risk factor for graft failure regardless of liver transplant type (p = 0.017, preformed; p = 0.002, de novo). In conclusion, although similar in prevalence, DSA may have more impact in DDLT than LDLT recipients. Although our findings need further validation, future research should more robustly test the effect of donor type and strategies to mitigate the impact of DSA. PMID:26896194

    Auxiliary partial orthotopic liver transplantation (APOLT) is a technique of liver transplantation (LT) where a partial liver graft is implanted in an orthotopic position after leaving behind a part of the native liver. APOLT was previously considered technically challenging with results inferior to orthotopic liver transplantation. Results of this procedure have continued to improve with improving surgical techniques and a better understanding of the natural history of acute liver failure (ALF) and liver regeneration. The procedure is being increasingly accepted as a valid treatment option for ALF-especially in children.

    Advances in the understanding of hepatocyte engraftment and repopulation of the host liver have already led to the use of hepatocyte transplantation (HT) with some success in the treatment of inherited and acquired liver diseases. Wider application of HT is severely limited by the unavailability of large number of transplantable hepatocytes and difficulties associated with transplanting an adequate number of cells for achieving therapeutically satisfactory levels of metabolic correction. Therefore, there is a need for preparative regimens that provide a growth advantage to the transplanted (healthy) hepatocytes over the host's own (diseased) hepatocytes so that the former can repopulate the host liver. We have recently shown that when the liver of recipient rats was subjected to radiotherapy and partial hepatectomy before HT, the transplanted hepatocytes engrafted in and massively repopulated the liver, and also ameliorated the adverse clinical and histopathological changes associated with hepatic irradiation. This protocol was then used as a preparative regimen for transplanting normal hepatocytes into jaundice mutant rats (Gunn strain), which lack hepatic bilirubin-uridinediphosphoglucuronate glucuronosyltransferase and is a model of Crigler-Najjar syndrome Type I. The results showed long-term correction of the metabolic abnormality, suggesting that the transplanted hepatocytes repopulated an irradiated liver and were metabolically functional. This strategy could be useful in the treatment of various genetic, metabolic, or malignant diseases of the liver. PMID:11173140

    Biliary complications such as ischemic (type) biliary lesions frequently develop following liver transplantation, requiring costly medical and endoscopic treatment. If conservative approaches fail, re-transplantation is most often an inevitable sequel. Because of an increasing donor organ shortage and unfavorable outcomes in hepatic re-transplantation, efforts to prolong graft survival become of particular interest. From a series of 1685 liver transplants, we herein report on three patients who underwent partial hepatic graft resection for (ischemic type) biliary lesions. In all cases, left hepatectomy (Couinaud's segments II, III and IV) was performed without Pringle maneuver or mobilization of the right liver. All patients fully recovered postoperatively, but biliary leakage required surgical revision twice in one patient. At last follow-up, two patients presented alive and well. The other patient with persistent hepatic artery thrombosis (HAT), however, demonstrated progression of disease in the right liver remnant and required re-transplantation 13 months after hepatic graft resection. Including our own patients, review of the literature identified 24 adult patients who underwent hepatic graft resection. In conclusion, partial graft hepatectomy can be considered a safe and beneficial procedure in selected liver transplant recipients with anatomical limited biliary injury, thereby, preserving scarce donor organs.

    For the development of innovative cell-based liver directed therapies, e.g. liver tissue engineering, the use of stem cells might be very attractive to overcome the limitation of donor liver tissue. Liver specific differentiation of embryonic, fetal or adult stem cells is currently under investigation. Different types of fetal liver (stem) cells during development were identified, and their advantageous growth potential and bipotential differentiation capacity were shown. However, ethical and legal issues have to be addressed before using fetal cells. Use of adult stem cells is clinically established, e.g. transplantation of hematopoietic stem cells. Other bone marrow derived liver stem cells might be mesenchymal stem cells (MSC). However, the transdifferentiation potential is still in question due to the observation of cellular fusion in several in vivo experiments. In vitro experiments revealed a crucial role of the environment (e.g. growth factors and extracellular matrix) for specific differentiation of stem cells. Co-cultured liver cells also seemed to be important for hepatic gene expression of MSC. For successful liver cell transplantation, a novel approach of tissue engineering by orthotopic transplantation of gel-immobilized cells could be promising, providing optimal environment for the injected cells. Moreover, an orthotopic tissue engineering approach using bipotential stem cells could lead to a repopulation of the recipients liver with healthy liver and biliary cells, thus providing both hepatic functions and biliary excretion. Future studies have to investigate, which stem cell and environmental conditions would be most suitable for the use of stem cells for liver regeneration or tissue engineering approaches.

    Leptospirosis has been rarely reported in solid organ transplant recipients. We report the first case to our knowledge of leptospirosis in a liver transplant recipient who developed jaundice and renal insufficiency. We describe his favorable clinical progression and discuss the possible mechanisms involved in the more benign disease course. We also review the previously published cases of leptospirosis in solid organ transplant recipients. Although this disease does not appear to present any particularities in this context, we highlight the importance of clinical suspicion in this setting, particularly after liver transplantation.

    It is well known that most organs for transplantation are currently procured from brain-dead donors; however, the presence of brain death is an important risk factor in liver transplantation. In addition, one of the mechanisms to avoid the shortage of liver grafts for transplant is the use of marginal livers, which may show higher risk of primary non-function or initial poor function. To our knowledge, very few reviews have focused in the field of liver transplantation using brain-dead donors; moreover, reviews that focused on both brain death and marginal grafts in liver transplantation, both being key risk factors in clinical practice, have not been published elsewhere. The present review aims to describe the recent findings and the state-of-the-art knowledge regarding the pathophysiological changes occurring during brain death, their effects on marginal liver grafts and summarize the more controversial topics of this pathology. We also review the therapeutic strategies designed to date to reduce the detrimental effects of brain death in both marginal and optimal livers, attempting to explain why such strategies have not solved the clinical problem of liver transplantation.

    BACKGROUND—Hepatoblastoma is an exceptional cause of primary malignant liver tumour in the adult.
PATIENT—The case is reported of an adult patient transplanted for alcoholic cirrhosis complicated by multifocal hepatocellular carcinoma in whom a recurrence in the form of a mixed hepatoblastoma invading the whole transplanted liver developed three months after liver transplantation.
METHODS—Complete clinical, histopathological, and immunohistochemical data were reviewed.
RESULTS—The recurrent tumour invaded the whole liver. The major component was a mixed hepatoblastoma, with an epithelial component expressing cytokeratin and a mesenchymal component expressing vimentin. The tumour also contained a minor hepatocarcinomatous component expressing α fetoprotein. The rapid growth of the tumour prevented any attempt at treatment. Although direct evidence is lacking, the most likely hypothesis to explain the observations is a marked phenotypic change in the initial malignant population at recurrence.
CONCLUSION—This case supports a possible filiation between hepatocellular carcinoma and hepatoblastoma in adults.

    2016-01-01

    Chronic hepatitis B is a global health problem that leads to development of various complications, such as cirrhosis, liver cancer, and liver failure requiring liver transplantation. The recurrence of hepatitis B virus (HBV) post-liver transplantation is a major cause of allograft dysfunction, cirrhosis of the allograft, and graft failure. Patients with high viral load at the time of transplantation, hepatitis B e antigen (HBeAg) positivity, or those with a history of anti-viral drug resistance are considered as high-risk for recurrent HBV post-liver transplantation, while patients with low viral load, including HBeAg negative status, acute liver failure, and hepatitis D virus (HDV) co-infection are considered to be at low-risk for recurrent HBV post-liver transplantation. Antivirals for patients awaiting liver transplantation(LT) cause suppression of HBV replication and reduce the risk of recurrent HBV infection of the allograft and, therefore, all HBV patients with decompensated cirrhosis should be treated with potent antivirals with high genetic barrier to resistance (entecavir or tenofovir) prior to liver transplantation. Prevention of post-liver transplantation recurrence should be done using a combination of hepatitis B immunoglobulin (HBIG) and antivirals in patients at high risk of recurrence. Low dose HBIG, HBIG-free protocols, and monoprophylaxis with high potency antivirals can still be considered in patients at low risk of recurrence. Even, marginal grafts from anti-HBc positive donors can be safely used in hepatitis B surface antigen (HBsAg) negative, preferably in anti-hepatitis B core (HBc)/anti-hepatitis B surface (HBs) positive recipients. In this article, we aim to review the mechanisms and risk factors of HBV recurrence post-LT in addition to the various treatment strategies proposed for the prevention of recurrent HBV infection PMID:27047773

    2016-05-01

    Nonalcoholic fatty liver disease (NAFLD) is the most common etiology of chronic liver disease in developed countries and is on trajectory to become the leading indication for liver transplantation in the USA and much of the world. Patients with NAFLD cirrhosis awaiting liver transplant face unique challenges and increased risk for waiting list stagnation and dropout due to burdensome comorbidities including obesity, diabetes, cardiovascular disease, and kidney disease. Thus far, patients transplanted for NAFLD cirrhosis have excellent mid- and long-term patient and graft survival, but concerns regarding short-term morbidity and mortality continue to exist. Post-liver transplantation, NAFLD occurs as both a recurrent and de novo manifestation, each with unique outcomes. NAFLD in the donor population is of concern given the growing demand for liver transplantation and mounting pressure to expand the donor pool. This review addresses key issues surrounding NAFLD as an indication for transplantation, including its increasing prevalence, unique patient demographics, outcomes related to liver transplantation, development of post-liver transplantation NAFLD, and NAFLD in the liver donor population. It also highlights exciting areas where further research is needed, such as the role of bariatric surgery and preconditioning of marginal donor grafts. PMID:26815171

    Liver transplant is the treatment of choice for end-stage liver disease. Management of transplant patients requires a multidisciplinary approach, with radiologists playing a key role in identifying complications in both symptomatic and asymptomatic patients. Ultrasonography remains the investigation of choice for the initial evaluation of symptomatic patients. Depending on the clinical situation, further evaluation with CT, MRI, or biopsy may be performed or clinical and imaging surveillance may be continued. This article discusses the various normal and abnormal imaging presentations of liver transplant patients, including various acute and chronic complications, and their management. PMID:26896220

    Orthotopic liver transplantation is the treatment of choice in adult patients with endstage liver disease. Survival of both graft and patient has progressively improved over time due to improvements in surgical and medical treatment. However, post-transplant complications still have a significant impact on morbidity and mortality associated with transplant surgery. The most common adverse events of the graft include vascular (arterial and venous stenosis and thrombosis), biliary (leakage, strictures, stones) and parenchymal complications (hepatitis virus C infection, HCC recurrence, liver abscesses). The diagnosis of these adverse events is often challenging because of the low specificity of clinical and biologic findings. Different diagnostic algorithms have been proposed for the detection of graft complications and, in this setting, radiological evaluation plays a key role in differential diagnosis of graft complications and the exclusion of other adverse events. Ultrasound examination is established the first-line method of identifying adverse events in liver transplant recipients but a normal or a technically unsatisfactory study cannot exclude the presence of biliary, vascular and/or parenchymal complications. In these circumstances, before planning any treatment, multi-detector CT and/or MR imaging and MR cholangiography should be performed for the evaluation of vascular structures, biliary system, liver parenchyma and fluid collections. The aim of this review is to illustrate the role and state-of-the-art of non-invasive cross-sectional imaging techniques in the diagnosis and management of complications which primarily affect the graft in patients after liver transplantation.

  3. Simultaneous Liver-Kidney Transplant: Too Many or Just Enough?

    2015-09-01

    For liver transplant candidates with advanced kidney dysfunction, simultaneous liver-kidney (SLK) transplantation is an important option. As the incidence of severe kidney dysfunction has increased over the past decade, so have the numbers of SLK transplants. This has engendered controversy within the transplant community because SLK transplants draw deceased donor kidneys from the kidney transplant candidate pool. Because kidney recovery after liver transplant alone (LTA) is difficult to predict, indications for SLK are not precisely defined. Candidates with hepatorenal syndrome can have kidney recovery after as much as 12 weeks on dialysis, whereas those with CKD may have early ESRD after LTA because of perioperative events and calcineurin inhibitor exposure. Although large observational studies generally show slightly improved survival in SLK recipients compared with LTA, inferences from these studies are limited by selection biases. Therefore, a true survival benefit of SLK in candidates without ESRD is still unproved. Although selection practices vary, generally LTA candidates have more kidney dysfunction because of hepatorenal syndrome and acute kidney injury, whereas SLK candidates have less severe liver disease and more CKD or ESRD. The debate over appropriate SLK is primarily one of the optimal kidney utilization vs the best interests of individual liver transplant candidates. PMID:26311602

    Background Because simultaneous liver and kidney transplantation has been limited as a standard practice because of a severe shortage of deceased donors in Japan, living donor (LD) liver transplantation alone (LTA) is indicated in most recipients with maintenance renal replacement therapy (MRRT). Methods A retrospective nationwide survey of LD LTA was performed for liver transplant patients on MRRT. The characteristics of donors and recipients, postoperative complications, survival rate, and causes of death were analyzed. Results In the adult cases (n = 28), the overall survival rate at 1 year and 5 years were 66.1% and 57.3%, respectively. When compared with those adults without MRRT (n = 237), it was significantly worse. In the 7 pediatric cases, the overall survival rate at 1 and 5 years were both 83.3%. Three adult recipients died of nonaneurysm cerebral hemorrhage after 1 year and 1 adult recipient died of acute heart failure after 7 months. In adult recipients with MRRT, graft weight versus standard liver volume, and duration and blood loss in LTA surgery were associated with poor outcomes after LD LTA. Multivariate analysis revealed that MRRT was highest hazard ratio on patient survival after LD LTA. Conclusions Early post-LD LTA mortality was higher in patients with MRRT than in those without MRRT with characteristic causes. Smaller grafts for size and a complicated surgery were associated with poor outcome after LD LTA. Thus, LD LTA in adult patients on MRRT should be carefully treated with meticulous postoperative management and follow-up.

    Introduction: Late acute rejection leads to worse patient and graft survival after liver transplantation. Aim: To analyze the reported results published in recent years by leading transplant centers in evaluating late acute rejection and update the clinical manifestations, diagnosis and treatment of liver transplantation. Method: Systematic literature review through Medline-PubMed database with headings related to late acute rejection in articles published until November 2013 was done. Were analyzed demographics, immunosuppression, rejection, infection and graft and patient survival rates. Results: Late acute rejection in liver transplantation showed poor results mainly regarding patient and graft survival. Almost all of these cohort studies were retrospective and descriptive. The incidence of late acute rejection varied from 7-40% in these studies. Late acute rejection was one cause for graft loss and resulted in different outcomes with worse patient and graft survival after liver transplant. Late acute rejection has been variably defined and may be a cause of chronic rejection with worse prognosis. Late acute rejection occurs during a period in which the goal is to maintain lower immunosuppression after liver transplantation. Conclusion: The current articles show the importance of late acute rejection. The real benefit is based on early diagnosis and adequate treatment at the onset until late follow up after liver transplantation. PMID:26537150

    Neonatal hemochromatosis (NH) is a severe neonatal liver injury that is confirmed by extra-hepatic iron accumulation. Although a recent study described treating NH with exchange transfusions and intravenous immunoglobulin, liver transplantation should be considered for patients with severe liver failure that does not respond to other medical treatment. Herein, we report the case of a two-month-old female infant who presented with persistent ascites and hyperbilirubinemia. Her laboratory findings demonstrated severe coagulopathy, high indirect and direct bilirubin levels, and high ferritin levels. Abdominal magnetic resonance imaging presented low signal intensity in the liver on T2-weighted images, suggesting iron deposition. The infant was diagnosed with NH as a result of the clinical findings and after congenital infection and metabolic diseases were excluded. The infant was successfully treated with a living-donor liver transplantation. Living related liver transplantation should be considered as a treatment option for NH in infants. PMID:27437193

    Most countries exclude human immunodeficiency virus (HIV)-positive patients from organ donation because of concerns regarding donor-derived HIV transmission. The Swiss Federal Act on Transplantation has allowed organ transplantation between HIV-positive donors and recipients since 2007. We report the successful liver transplantation from an HIV-positive donor to an HIV-positive recipient. Both donor and recipient had been treated for many years with antiretroviral therapy and harbored multidrug-resistant viruses. Five months after transplantation, HIV viremia remains undetectable. This observation supports the inclusion of appropriate HIV-positive donors for transplants specifically allocated to HIV-positive recipients. PMID:27109874

    Heart, lung, kidney, liver, and simultaneous liver-kidney transplants share many features. They all follow the same 7-step process, the same 3 immunosuppressant medications, and the same reason for organ transplantation. Organs are transplanted because of organ failure. The similarities end there. Each organ has its unique causes for failure. Each organ also has its own set of criteria that must be met prior to transplantation. Simultaneous liver-kidney transplant criteria vary per transplant center but are similar in nature. Both the criteria required and the 7-step process are described by the United Network of Organ Sharing, which is a private, nonprofit organization, under contract with the US Department of Health and Human Services. Its function is to increase the number of transplants, improve survival rates after transplantation, promote safe transplant practices, and endorse efficiency. The purpose of this article is to review the reasons transplant is needed, specifically heart, lung, kidney, liver, and simultaneous liver-kidney, and a brief overview of the transplant process including criteria used, contraindications, and medications prescribed.

    Liver transplantation, although now a routine procedure, with defined indications and usually excellent outcomes, still has challenges. Donor shortage remains a key issue. Transplanted organs are not free of risk and may transmit cancer, infection, metabolic or autoimmune disease. Approaches to the donor shortage include use of organs from donors after circulatory death, from living donors and from those previously infected with Hepatitis B and C and even HIV for selected recipients. Normothermic regional and/or machine perfusion, whether static or pulsatile, normo- or hypothermic, are being explored and will be likely to have a major place in improving donation rates and outcomes. The main indications for liver replacement are alcoholic liver disease, HCV, non-alcoholic liver disease and liver cancer. Recent studies have shown that selected patients with severe alcoholic hepatitis may also benefit from liver transplant. The advent of new and highly effective treatments for HCV, whether given before or after transplant will have a major impact on outcomes. The role of transplantation for those with liver cell cancer continues to evolve as other interventions become more effective. Immunosuppression is usually required life-long and adherence remains a challenge, especially in adolescents. Immunosuppression with calcineurin inhibitors (primarily tacrolimus), antimetabolites (azathioprine or mycophenolate) and corticosteroids remains standard. Outcomes after transplantation are good but not normal in quality or quantity. Premature death may be due to increased risk of cardiovascular disease, de novo cancer, recurrent disease or late technical problems. PMID:26350881

    2013-01-01

    Hepatitis C virus (HCV) is a small-enveloped RNA virus belonging to the Flaviviridae family. Since first identified in 1989, HCV has been estimated to infect 170 million people worldwide. Mostly chronic hepatitis C virus has a uniform natural history, from liver cirrhosis to the development of hepatocellular carcinoma. The current therapy for HCV infection consists of a combination of Pegylated interferon and ribavirin. On the other hand, HCV-related liver disease is also the leading indication for liver transplantation. However, posttransplant HCV re-infection of the graft has been reported to be universal. Furthermore, the graft after HCV re-infection often results in accelerated progression to liver failure. In addition, treatment of recurrent HCV infection after liver transplantation is often compromised by enhanced adverse effects and limited efficacy of interferon-based therapies. Taken together, poor outcome after HCV re-infection, regardless of grafts or recipients, poses a major issue for the hepatologists and transplant surgeons. The aim of this paper is to review several specific aspects regarding HCV re-infection after transplant: risk factors, current therapeutics for HCV in different stages of liver transplantation, cellular function of HCV proteins, and molecular mechanisms of HCV entry. Hopefully, this paper will inspire new strategies and novel inhibitors against recurrent HCV infection after liver transplantation and greatly improve its overall outcome. PMID:23710205

    Health care has shifted to placing priority on quality and value instead of volume. Liver transplantation uses substantial resources and is associated with high readmission rates. Our goal was to determine if a protocol designed to reduce readmission after liver transplant was effective. We conducted a prospective study of a protocol designed to reduce readmission rates after liver transplantation by expanding outpatient services and alternatives to readmission. The 30-day readmission rate 1 year after implementing the protocol was compared to the 30-day rate for 2 years prior to implementation. Multivariate analysis was used to control for potential confounding factors. Over the study period, 167 adult primary liver transplants were performed with a mean biological Model for End-Stage Liver Disease score of 21 ± 8. Fifty-seven (34%) patients were readmitted. The most common reason for readmission was biliary complications (n = 13). The 30-day readmission rate decreased from 40% before implementing the protocol to 20% after implementation (P = 0.02). In multivariate analysis, the protocol remained associated with readmission (odds ratio, 0.39; 95% confidence interval, 0.16-0.92; P = 0.03). The mean length of stay after transplant was 13 ± 12 days preprotocol and 9 ± 5 days postprotocol (P = 0.09). Alternatives to readmission, including hospital lodging and observation status, were main factors in reducing readmission rates. If the most recent definitions of inpatient admission and observation status were applied over the entire study period, then the readmission rates preprotocol and postprotocol were 31% and 20% indicating that the revised definition of observation status accounted for 45% of the reduction in the readmission rate. Readmission after liver transplantation can be reduced without increasing length of stay by implementing a specifically designed protocol that expands outpatient services and alternatives to inpatient

    Liver transplantation is the optimal treatment for many patients with advanced liver disease, including decompensated cirrhosis, hepatocellular carcinoma and acute liver failure. Organ shortage is the main determinant of death on the waiting list and hence living donor liver transplantation (LDLT) assumes importance. Biliary complications are the most common post operative morbidity after LDLT and occur due to anatomical and technical reasons. They include biliary leaks, strictures and cast formation and occur in the recipient as well as the donor. The types of biliary complications after LDLT along with their etiology, presenting features, diagnosis and endoscopic and surgical management are discussed. PMID:26207167

    A Bayesian simulation model has been applied to a database developed for split liver transplantation on two adult recipients (SLT A/A) in the context of a macroregional project funded by the Italian Ministry of Health. The model was entered within Bayesian inference Using Gibbs Sampling (WinBUGS), a free software for Bayesian analysis of complex statistical models using Markov chain Monte Carlo techniques developed by the MRC Biostatistics Unit Cambridge jointly with the Imperial College School of Medicine at St Mary's, London. The model was built by using data entry performed from January 1, 2005 to August 5, 2005. In that period, 20 potential donors suitable for the SLT A/A procedure were entered into the database. We only selected the continuous and dichotomous donor-related variables (DRV, n = 62) for which almost one data entry procedure. The model assumed that a database user learned during data entry procedures for each donor, and that the probability of a successful input may depend on the number of previous errors and corrections. After binary transformation of the DRV (value 0 for each input record, value 1 for each no input record), we calculated an overall value of 0.28 +/- 0.27 (median: 0.3; 95% confidence interval: from 0.18 to 0.629). The transformed DRV were entered within the WinBUGS environment after model specification, assuming as success (y = 1) each procedure of input record, and as failure (y = 0) each procedure of no input record. A unequivocal convergence was obtained after 10,000 iterations, and a simulation run was launched for a further 10,000 updates. We obtained a negligible Monte Carlo error and a fine profile in the kernel density plot. This study supported the application of simulation models to databases concerning liver transplantation as a useful strategy to identify a critical state in the data entry process. PMID:17692652

    Orthotopic liver transplantation in the mouse is a powerful research tool that has led to important mechanistic insights into the regulation of hepatic injury, liver immunopathology, and transplant tolerance. However, it is a technically demanding surgical procedure. Setup of the orthotopic liver transplantation model comprises three main stages: surgery on the donor mouse; back-table preparation of the liver graft; and transplant of the liver into the recipient mouse. In this protocol, we describe our procedure in stepwise detail to allow efficient completion of both the donor and recipient operations. The protocol can result in consistently high technical success rates when performed by personnel experienced in the protocol. The technique can be completed in ∼2-3 h when performed by an individual who is well practiced in performing mouse transplantation in accordance with this protocol. We have achieved a perioperative survival rate close to 100%. PMID:27254462

    Donation after circulatory death (DCD) liver transplantation (LT) may imply a risk for decreased graft survival, caused by posttransplantation complications such as primary nonfunction or ischemic-type biliary lesions. However, similar survival rates for DCD and donation after brain death (DBD) LT have been reported. The objective of this study is to determine the longterm outcome of DCD LT in the Eurotransplant region corrected for the Eurotransplant donor risk index (ET-DRI). Transplants performed in Belgium and the Netherlands (January 1, 2003 to December 31, 2007) in adult recipients were included. Graft failure was defined as either the date of recipient death or retransplantation whichever occurred first (death-uncensored graft survival). Mean follow-up was 7.2 years. In total, 126 DCD and 1264 DBD LTs were performed. Kaplan-Meier survival analyses showed different graft survival for DBD and DCD at 1 year (77.7% versus 74.8%, respectively; P = 0.71), 5 years (65.6% versus 54.4%, respectively; P = 0.02), and 10 years (47.3% versus 44.2%, respectively; P = 0.55; log-rank P = 0.038). Although there was an overall significant difference, the survival curves almost reach each other after 10 years, which is most likely caused by other risk factors being less in DCD livers. Patient survival was not significantly different (P = 0.59). Multivariate Cox regression analysis showed a hazard ratio of 1.7 (P < 0.001) for DCD (corrected for ET-DRI and recipient factors). First warm ischemia time (WIT), which is the time from the end of circulation until aortic cold perfusion, over 25 minutes was associated with a lower graft survival in univariate analysis of all DCD transplants (P = 0.002). In conclusion, DCD LT has an increased risk for diminished graft survival compared to DBD. There was no significant difference in patient survival. DCD allografts with a first WIT > 25 minutes have an increased risk for a decrease in graft survival. Liver Transplantation 22 1107

    Complete surgical resection is essential to long-term survival in children with hepatoblastoma. We present the guidelines from the Children's Oncology Group (COG), liver tumor study group of the Societe Internationale Oncologie Pediatrique (SIOPEL), and German Pediatric Oncology Group (GPOH) for early referral of children with potentially unresectable hepatoblastoma to a specialty center with expertise in extreme resection and liver transplantation. Patients who will become candidates for liver transplantation should receive chemotherapy following the same protocols as for children undergoing a partial hepatectomy. The Pediatric Liver Unresectable Tumor Observatory (PLUTO) is an international prospective database established to collect data and make future recommendations on controversial issues regarding the use of transplant in hepatoblastoma including: 1) What is the optimal treatment of multifocal tumors. 2) What is the role of extreme resection vs. liver transplant in patients with major venous involvement. 3) What is the role of transplant in patients who present with lung metastasis. 3) Should patients with tumor relapse be offered a rescue transplant. 4) What is the role of pre- and post- transplant chemotherapy.

    Relevant changes in cerebral circulation occur during "Piggy Back" liver transplantation. Particularly at the washout-reperfusion time the cerebral perfusion suddenly changes from its lowest to its highest values. Further investigation is required to evaluate whether patients with the greatest change in cerebral oxygenation at this time point will suffer neurological complications after transplantation.

    Hepatitis C virus (HCV) is a major health problem that leads to chronic hepatitis, cirrhosis and hepatocellular carcinoma, being the most frequent indication for liver transplantation in several countries. Unfortunately, HCV re-infects the liver graft almost invariably following reperfusion, with an accelerated history of recurrence, leading to 10%-30% of patients progressing to cirrhosis within 5 years of transplantation. In this sense, some groups have even advocated for not re-transplanting this patients, as lower patient and graft outcomes have been reported. However, the management of HCV recurrence is being optimized and several strategies to reduce post-transplant recurrence could improve outcomes, decrease the rate of re-transplantation and optimize the use of available grafts. Three moments may be the focus of potential actions in order to decrease the impact of viral recurrence: the pre-transplant moment, the transplant environment and the post-transplant management. In the pre-transplant setting, it is not well established if reducing the pre transplant viral load affects the risk for HCV progression after transplant. Obviously, antiviral treatment can render the patient HCV RNA negative post transplant but the long-term benefit has not yet been fully established to justify the cost and clinical risk. In the transplant moment, factors as donor age, cold ischemia time, graft steatosis and ischemia/reperfusion injury may lead to a higher and more aggressive viral recurrence. After the transplant, discussion about immunosuppression and the moment to start the treatment (prophylactic, pre-emptive or once-confirmed) together with new antiviral drugs are of interest. This review aims to help clinicians have a global overview of post-transplant HCV recurrence and strategies to reduce its impact on our patients. PMID:23717735

    The liver is the second most-often transplanted solid organ after the kidney, so it is clear that liver disease is a common and serious problem around the globe. With the advancements in surgical, oncological and imaging techniques, orthotopic liver transplantation has become the first-line treatment for many patients with end-stage liver disease. Ultrasound, and Doppler are the most economical and cost-effective imaging modalities for evaluating postoperative fluid collections and vascular complications. Computed tomography (CT) is used to confirm the findings of ultrasound and look for pulmonary complications. Magnetic resonance imaging (MRI) is used for the diagnosis of biliary complications, bile leaks and neurological complications. This article illustrates the imaging options for diagnosing the various complications that can be encountered in the postoperative period after liver transplantation. PMID:26534929

    A disintegrin-like and metalloproteinase with thrombospondin type-1 motifs 13 (ADAMTS13) specifically cleaves unusually-large von Willebrand factor (VWF) multimers under high shear stress, and down-regulates VWF function to form platelet thrombi. Deficiency of plasma ADAMTS13 activity induces a life-threatening systemic disease, termed thrombotic microangiopathy (TMA) including thrombotic thrombocytopenic purpura (TTP). Children with advanced biliary cirrhosis due to congenital biliary atresia sometimes showed pathological features of TMA, with a concomitant decrease of plasma ADAMTS13 activity. Disappearance of their clinical findings of TTP after successful liver transplantation suggested that the liver is a major organ producing plasma ADAMTS13. In situ hybridization analysis showed that ADAMTS13 was produced by hepatic stellate cells. Subsequently, it was found that ADADTS13 was not merely responsible to development of TMA and TTP, but also related to some kinds of liver dysfunction after liver transplantation. Ischemia-reperfusion injury and acute rejection in liver transplant recipients were often associated with marked decrease of ADAMTS13 and concomitant formation of unusually large VWF multimers without findings of TMA/TTP. The similar phenomenon was observed also in patients who underwent hepatectomy for liver tumors. Imbalance between ADAMTS13 and VWF in the hepatic sinusoid might cause liver damage due to microcirculatory disturbance. It can be called as “local TTP like mechanism” which plays a crucial role in liver dysfunction after liver transplantation and surgery. PMID:26167250

    ABSTRACT This study aims to investigate the causes and treatment experience of severe abdominal infection after orthotopic liver transplantation. Clinical data were retrospectively analysed in perioperative severe abdominal infection of 186 orthotopic liver transplantation cases from March 2004 to November 2011. Among the 186 patients, 16 cases had severe abdominal infection: five cases had bile duct anastomotic leakage-inducing massive hydrops and infection under liver interstice, 10 cases had extensive bleeding of surgical wound leading to massive haematocele and infection around the liver, and one case had postoperative lower oesophageal fistula leakage causing massive hydrops and infection under the left diaphragm. After definite diagnosis, 12 cases underwent surgery within three days, with no death. Among the four cases that underwent surgery three days after diagnosis, one case died of multiple-organ failure five days after abdominal cavity exploration, which was performed 21 days after liver transplantation. Severe abdominal infections after liver transplantation were the most common causes of death in perioperative liver transplantation. Comprehensive treatment with efficacious antibiotics, multiple-organ support, controlled surgical removal of the lesion, and adequate drainage establishment was the key to the entire treatment.

    Glycogen storage disease type I (GSDI), an inborn error of carbohydrate metabolism, is caused by defects in the glucose-6-transporter/glucose-6-phosphatase complex, which is essential in glucose homeostasis. Two types exist, GSDIa and GSDIb, each caused by different defects in the complex. GSDIa is characterized by fasting intolerance and subsequent metabolic derangements. In addition to these clinical manifestations, patients with GSDIb suffer from neutropenia with neutrophil dysfunction and inflammatory bowel disease.With the feasibility of novel cell-based therapies, including hepatocyte transplantations and liver stem cell transplantations, it is essential to consider long term outcomes of liver replacement therapy. We reviewed all GSDI patients with liver transplantation identified in literature and through personal communication with treating physicians. Our review shows that all 80 GSDI patients showed improved metabolic control and normal fasting tolerance after liver transplantation. Although some complications might be caused by disease progression, most complications seemed related to the liver transplantation procedure and subsequent immune suppression. These results highlight the potential of other therapeutic strategies, like cell-based therapies for liver replacement, which are expected to normalize liver function with a lower risk of complications of the procedure and immune suppression.

    Iatrogenic aluminium toxicity is reported in a patient who underwent an orthotopic liver transplant and who had concomitant renal failure requiring hemodialysis. Following transplantation the patient developed a metabolic encephalopathy with only mildly elevated blood ammonia concentrations. During the period following transplantation the patient received massive infusions of albumin and was on oral feeding (vivonexten), both of which contained aluminium, as did the dialysis fluid. Hyperaluminemia and profoundly elevated liver tissue aluminium concentrations were observed. Treatment with desferrioxamine, a trivalent ion chelator, decreased the plasma aluminium concentrations with an improvement in the patient's mental status. PMID:7579738

    Hepatolithiasis, originally as oriental cholangiohepatitis, especially prevails in Asia, but globalization and intercontinental migration have also converted the endemic disease dynamics around the world. Characterized by its high incidence of ineffective treatment and recurrence, hepatolithiasis, always, poses a therapeutic challenge to global doctors. Although the improved surgical and non-surgical techniques have evolved over the past decade, incomplete clearance and recurrence of calculi are always so common and disease-related mortality from liver failure and concurrent cholangiocarcinoma still exists in the treatment of hepatolithiasis. In the late stage of hepatolithiasis, is it suitable for liver transplantation (LT)? Herein, we propose a comprehensive review and analysis of the LTx currently in potential use to treat hepatolithiasis. In our subjective opinion, and as is objective from the literatures so far, also given the strict indications, LT remains one of the definitive treatments for terminal hepatolithiasis. PMID:26947018

    Bleeding and coagulopathy are critical issues complicating pediatric liver transplantation and contributing to morbidity and mortality in the cirrhotic child. The complexity of coagulopathy in the pediatric patient is illustrated by the interaction between three basic models. The first model, “developmental hemostasis”, demonstrates how a different balance between pro- and anticoagulation factors leads to a normal hemostatic capacity in the pediatric patient at various ages. The second, the “cell based model of coagulation”, takes into account the interaction between plasma proteins and cells. In the last, the concept of “rebalanced coagulation” highlights how the reduction of both pro- and anticoagulation factors leads to a normal, although unstable, coagulation profile. This new concept has led to the development of novel techniques used to analyze the coagulation capacity of whole blood for all patients. For example, viscoelastic methodologies are increasingly used on adult patients to test hemostatic capacity and to guide transfusion protocols. However, results are often confounding or have limited impact on morbidity and mortality. Moreover, data from pediatric patients remain inadequate. In addition, several interventions have been proposed to limit blood loss during transplantation, including the use of antifibrinolytic drugs and surgical techniques, such as the piggyback and lowering the central venous pressure during the hepatic dissection phase. The rationale for the use of these interventions is quite solid and has led to their incorporation into clinical practice; yet few of them have been rigorously tested in adults, let alone in children. Finally, the postoperative period in pediatric cohorts of patients has been characterized by an enhanced risk of hepatic vessel thrombosis. Thrombosis in fact remains the primary cause of early graft failure and re-transplantation within the first 30 d following surgery, and it occurs despite prolongation

    Severe geographic disparities exist in liver transplantation; for patients with comparable disease severity, 90-day transplant rates range from 18%–86% and death rates range from 14%–82% across donor service areas (DSAs). Broader sharing has been proposed to resolve geographic inequity; however, we hypothesized that the efficacy of broader sharing depends on the geographic partitions used. To determine the potential impact of redistricting on geographic disparity in disease severity at transplantation, we combined existing DSAs into novel regions using mathematical redistricting optimization. Optimized maps and current maps were evaluated using the Liver Simulated Allocation Model. Primary analysis was based on 6700 deceased donors, 28,063 liver transplant candidates, and 242,727 Model of End-Stage Liver Disease (MELD) changes in 2010. Fully regional sharing within the current regional map would paradoxically worsen geographic disparity (variance in MELD at transplantation increases from 11.2 to 13.5, p=0.021), although it would decrease waitlist deaths (from 1368 to 1329, p=0.002). In contrast, regional sharing within an optimized map would significantly reduce geographic disparity (to 7.0, p=0.002) while achieving a larger decrease in waitlist deaths (to 1307, p=0.002). Redistricting optimization, but not broader sharing alone, would reduce geographic disparity in allocation of livers for transplant across the United States. PMID:23837931

    The classical form of alpha-1-antitrypsin deficiency (A1ATD) is known to cause liver disease in children and adults, but there is relatively little information about the risk of severe, progressive liver disease and the need for liver transplantation. To better understand how newly evolving pharmacological, genetic, and cellular therapies may be targeted according to risk for progressive liver disease, we sought to determine the age distribution of A1ATD as a cause of severe liver disease, as defined by the need for liver transplantation. Using 3 US liver transplantation databases for the period 1991-2012, we found 77.2% of 1677 liver transplants with a reported diagnosis of A1ATD were adults. The peak age range was 50-64 years. Using 2 of the databases which included specific A1AT phenotypes, we found that many of these adults who undergo liver transplantation with A1ATD as the diagnosis are heterozygotes and have other potential causes of liver disease, most notably obesity and ethanol abuse. However, even when these cases are excluded and only ZZ and SZ phenotypes are considered, severe liver disease requiring transplantation is more than 2.5 times as likely in adults. The analysis also showed a markedly increased risk for males. In the pediatric group, almost all of the transplants are done in children less than 5 years of age. In conclusion, A1ATD causes progressive liver disease most commonly in adults with males in the highest risk category. In the pediatric group, children less than 5 years of age are highest in risk. These results suggest that A1ATD most commonly causes liver disease by mechanisms similar to age-dependent degenerative diseases and more rarely in children by powerful modifiers.

    Liver transplantation (LT) is used to treat both adult and pediatric patients with end-stage liver disease or acute liver failure. It has become more prevalent as both the surgical technique and postoperative care have improved resulting in a reduced morbidity and mortality. As a result, there are more patients surviving longer after liver transplantation. Despite this, there remain serious complications from the procedure that have a significant outcome on the patient and may result in retransplantation. At the same time, there have been significant advances in the field of interventional radiology both in terms of technology and how these apply to the patients. In this paper, we review the commonest complications, diagnostic tests, and interventional management options available. PMID:27335821

    In our current era where shortage of liver grafts is commonplace, utilization of traumatic liver grafts may represent an opportunity to expand the organ donor pool without compromising graft survival. However, data on liver transplantation using a fractured liver allograft is scarce, with only small case series and reports found in the literature. In this report, we describe our experience with utilizing a liver graft with grade IV hepatic fracture for transplantation. At 12 months follow up, the recipient has excellent graft function and has regained an excellent quality of life. We demonstrated that the ability to safely use a fractured liver graft represents an additional avenue for expansion of the deceased donor population, especially in regions with prolonged waitlist times.

    Portopulmonary hypertension is one of the main pulmonary conditions affecting patients with liver disease and/or portal hypertension. Other conditions include hepatopulmonary syndrome and hepatic hydrothorax. Portopulmonary hypertension is caused by pulmonary vasoconstriction and increased pulmonary vascular resistance. It develops as a result of portal hypertension with or without liver disease and is associated with a higher morbidity and mortality. However, portopulmonary hypertension is usually asymptomatic; the most common symptoms are dyspnea, fatigue, and peripheral edema. All liver transplant candidates should be screened for potential portopulmonary hypertension because its coexistence can affect survival rates after transplant. All patients with cirrhosis who present with dyspnea should also be screened. Transthoracic echocardiography is a noni nvasive, useful method for screening, but right heart-sided catheterization remains the criterion standard for diagnosis. Portopulmonary hypertension carries a poor prognosis without liver transplant, and its severe form is considered to be a contraindication for liver transplant. Treating patients with pulmonary arterial hypertension-specific therapies before liver transplant for moderate and severe portopulmonary hypertension appears to be beneficial. PMID:27015528

    Despite MHC incompatibility, Lewis to DA rat liver transplants survive indefinitely without immunosuppression, and the studies we report sought the mechanism(s) responsible for this. At one year most of the liver reacted positively to host anti-DA antibody. When small (50%) grafts were transplanted, recruitment was more rapid as most of the organ assumed the host phenotype at 3 months. After transplantation the Y-chromosome was detected in the hepatocytes of XX to XY grafts by both in-situ hybridization and PCR. Further, livers from transgenic Lewis rats carrying strong GFP markers lost the marker with time after transplantation to DA, GFP− hosts. Few liver cells contained the Y chromosome in syngeneic XX to XY liver grafts or when the hosts of Lewis XX to DA XY allografts were treated with cyclosporine A (CsA) 10mgs/kg/day. This dosage also impeded enlargement of the liver at ten days. Using GFP+ XX Lewis donors transplanted to GFP− XY DA hosts, we found little Y DNA in GFP+ cells at 10 days. Host derived OV-6 and c-kit positive, albumen positive cells were present at 3-10 days, but cells with the CD34 marker were less common and some clearly still had the donor phenotype at ten days. CXCR-4 positive cells increased with time and were abundant at 1 month after transplantation. We conclude: 1. extra-hepatic cells can differentiate into liver tissues; 2. regenerative stimuli accelerate stem cell recruitment; 3. both regeneration and recruitment are impeded by CsA immunosuppression, and 4. donor GFP positive cells contained little host Y-chromosome after transplantation suggesting that cell fusion was uncommon and, therefore, unlikely to be the mechanism leading to the changes in genotype and phenotype we observed.

    OBJECTIVE: The authors sought to train an artificial neural network to predict early outcomes after orthotopic liver transplantation. SUMMARY BACKGROUND DATA: Reliable prediction of outcomes early after liver transplantation would help improve organ use and could have an impact on patient survival, but remains an elusive goal. Traditional multivariate models have failed to attain the sensitivity and specificity required for practical clinical use. Alternate approaches that can help us model clinical phenomena must be explored. One such approach is the use of artificial neural networks, or connectionist models. These are computation systems that process information in parallel, using large numbers of simple units, and excel in tasks involving pattern recognition. They are capable of adaptive learning and self-organization, and exhibit a high degree of fault tolerance. METHODS: Ten feed-forward, back-propagation neural networks were trained to predict graft outcomes, using data from 155 adult liver transplants. The data included information that was available by the second postoperative day. Ten separate training and testing data subsets were prepared, using random sampling, and the ability of the different networks to predict outcomes successfully was evaluated using receiver operating characteristic (ROC) curve analysis. RESULTS: Four of the networks showed perfect discrimination, with an area under the ROC curve (Az) of 1.0. Two other networks also had excellent performance, with an Az of 0.95. The sensitivity and specificity of the combined networks was 60% and 100%, respectively, when using an output neuron activation of 0.6 as the cutoff point to decide class membership. Lowering the cutoff point to 0.14 increased the sensitivity to 77%, and lowered the specificity to 96%. CONCLUSIONS: These results are encouraging, especially when compared to the performance of more traditional multivariate models on the same data set. The robustness of neural networks, when

    The transplanted liver appears resistant to antibody-mediated injury compared to other transplanted organs such as kidney or heart. However, a growing number of reports suggest that alloantibody to the liver is associated with poorer outcomes. The data surrounding this field are unclear, and their interpretation remains controversial. Mechanistically, there is not a clear explanation for the liver's resistance to antibody-mediated injury, and the pathological criteria for antibody-mediated rejection (AMR) remain ill-defined. Furthermore, treatment of AMR is non-uniform. The field would benefit from better outcome data based on measurement of antibody at the time of transplantation and at the time of rejection. Consensus opinion regarding antibody and the liver might emerge with better standardization of antibody measurement and pathological definition of AMR. PMID:25510576

    Cardiovascular complications are a major cause of morbidity and mortality in patients with end-stage liver disease (ESLD) undergoing liver transplantation. Identifying candidates at the highest risk of postoperative cardiovascular complications is the cornerstone for optimizing the outcome. Ischaemic heart disease contributes to major portion of cardiovascular complications and therefore warrants evaluation in the preoperative period. Patients of ESLD usually demonstrate increased cardiac output, compromised ventricular response to stress, low systemic vascular resistance and occasionally bradycardia. Despite various recommendations for preoperative evaluation of cardiovascular disease in liver transplant candidates, a considerable controversy on screening methodology persists. This review critically focuses on the rapidly expanding body of evidence for diagnosis and risk stratification of cardiovascular disorder in liver transplant candidates. PMID:26962249

    The main goal of 2-stage liver transplant is to provide time to obtain a new liver source. We describe our experience of 3 patients with 3 different clinical conditions. A 57-year-old man was retransplanted successfully with this technique due to hepatic artery thrombosis. However, a 38-year-old woman with fulminant toxic hepatitis and a 5-year-old-boy with abdominal trauma had poor outcome. This technique could serve as a rescue therapy for liver transplant patients who have toxic liver syndrome or abdominal trauma. These patients required intensive support during long anhepatic states. The transplant team should decide early whether to use this technique before irreversible conditions develop. PMID:25894175

    Living related living transplantation (LRLT) has opened new possibilities for planning transplantation in better conditions for children with emergency situations and chronic liver diseases. Since we began the LRLT program in 1999, we have performed 57 pediatric liver transplants, 17 (29.8%) using living related donors (LRD). The aim of this study was to analyze the reasons why LRD were discarded as a therapeutic option. All pediatric patients were prospectively included in our Microsoft Excel database that was reviewed for obtaining information about causes why the LRLT could not be done. LRLT was proposed in 28 cases and performed in 17 (60.7%). The reasons for LRD rejection were: parent's fear of surgical complications in four cases; drug abuse in two; a mother without family support; medical reasons in two; and only one, due to anatomical reasons and in one case, cadaveric graft transplantation was performed while completing the father's evaluation. From these eleven cases, the indications for liver transplant were acute liver failure (ALF) in seven, biliary atresia in three, and Alagille syndrome in one. Nine were transplanted with cadaveric organs, but two patients with ALF died awaiting a liver.

    The current standard for liver preservation involves cooling of the organ on ice (0-4 °C). Although it is successful for shorter durations, this method of preservation does not allow long-term storage of the liver. The gradual loss of hepatic viability during preservation puts pressure on organ sharing and allocation, may limit the use of suboptimal grafts and necessitates rushed transplantation to achieve desirable post-transplantation outcomes. In an attempt to improve and prolong liver viability during storage, alternative preservation methods are under investigation. For instance, ex vivo machine perfusion systems aim to sustain and even improve viability by supporting hepatic function at warm temperatures, rather than simply slowing down deterioration by cooling. Here we describe a novel subzero preservation technique that combines ex vivo machine perfusion with cryoprotectants to facilitate long-term supercooled preservation. The technique improves the preservation of rat livers to prolong storage times as much as threefold, which is validated by successful long-term recipient survival after orthotopic transplantation. This protocol describes how to load rat livers with cryoprotectants to prevent both intracellular and extracellular ice formation and to protect against hypothermic injury. Cryoprotectants are loaded ex vivo using subnormothermic machine perfusion (SNMP), after which livers can be cooled to -6 °C without freezing and kept viable for up to 96 h. Cooling to a supercooled state is controlled, followed by 3 h of SNMP recovery and orthotopic liver transplantation. PMID:25692985

    Patient: Female, 21 Final Diagnosis: Unresectable liver adenomatosis associated with congenital absence of portal vein Symptoms: — Medication: — Clinical Procedure: Living donor liver transplantation Specialty: Transplantology Objective: Rare disease Background: Abernethy malformation (AM), or congenital absence of portal vein (CAPV), is a very rare disease which tends to be associated with the development of benign or malignant tumors, usually in children or young adults. Case Report: We report the case of a 21-year-old woman diagnosed with type Ib AM (portal vein draining directly into the inferior vena cava) and unresectable liver adenomatosis. The patient presented mild liver dysfunction and was largely asymptomatic. Living donor liver transplantation was performed using a left hemiliver graft from her mother. Postoperatively, the patient attained optimal liver function and at 9-month follow-up has returned to normal life. Conclusions: We consider that living donor liver transplantation is the best therapeutic solution for AM associated with unresectable liver adenomatosis, especially because compared to receiving a whole liver graft, the waiting time on the liver transplantation list is much shorter.

    Living donor liver transplantation (LDLT) is a comparable alternative to deceased donor liver transplantation and can mitigate the risk of dying while waiting for transplant. Although evidence exists of decreased utilization of living donor kidney transplants among racial minorities, little is known about access to LDLT among racial/ethnic minorities. We used Organ Procurement and Transplantation Network/United Network for Organ Sharing data from February 27, 2002 to June 4, 2014 from all adult liver transplant recipients at LDLT-capable transplant centers to evaluate differential utilization of LDLTs based on race/ethnicity. We then used data from 2 major urban transplant centers to analyze donor inquiries and donor rule-outs based on racial/ethnic determination. Nationally, of 35,401 total liver transplant recipients performed at a LDLT-performing transplant center, 2171 (6.1%) received a LDLT. In multivariate generalized estimating equation models, racial/ethnic minorities were significantly less likely to receive LDLTs when compared to white patients. For cholestatic liver disease, the odds ratios of receiving LDLT based on racial/ethnic group for African American, Hispanic, and Asian patients compared to white patients were 0.35 (95% CI, 0.20-0.60), 0.58 (95% CI, 0.34-0.99), and 0.11 (95% CI, 0.02-0.55), respectively. For noncholestatic liver disease, the odds ratios by racial/ethnic group were 0.53 (95% CI, 0.40-0.71), 0.78 (95% CI, 0.64-0.94), and 0.45 (95% CI, 0.33-0.60) respectively. Transplant center-specific data demonstrated that African American patients received fewer per-patient donation inquiries than white patients, whereas fewer African American potential donors were ruled out for obesity. In conclusion, racial/ethnic minorities receive a disproportionately low percentage of LDLTs, due in part to fewer initial inquiries by potential donors. This represents a major inequality in access to a vital health care resource and demands outreach to both

    Abstract Aim and background. The Nordic Liver Transplant Registry (NLTR) accounts for all liver transplants performed in the Nordic countries since the start of the transplant program in 1982. Due to short waiting times, donor liver allocation has been made without considerations of the model of end-stage liver disease (MELD) score. We aimed to summarize key outcome measures and developments for the activity up to December 2013. Materials and methods. The registry is integrated with the operational waiting-list and liver allocation system of Scandiatransplant (www.scandiatransplant.org) and accounted at the end of 2013 for 6019 patients out of whom 5198 were transplanted. Data for recipient and donor characteristics and relevant end-points retransplantation and death are manually curated on an annual basis to allow for statistical analysis and the annual report. Results. Primary sclerosing cholangitis, acute hepatic failure, alcoholic liver disease, primary biliary cirrhosis and hepatocellular carcinoma are the five most frequent diagnoses (accounting for 15.3%, 10.8%, 10.6%, 9.3% and 9.0% of all transplants, respectively). Median waiting time for non-urgent liver transplantation during the last 10-year period was 39 days. Outcome has improved over time, and for patients transplanted during 2004–2013, overall one-, five- and 10-year survival rates were 91%, 80% and 71%, respectively. In an intention-to-treat analysis, corresponding numbers during the same time period were 87%, 75% and 66%, respectively. Conclusion. The liver transplant program in the Nordic countries provides comparable outcomes to programs with a MELD-based donor liver allocation system. Unique features comprise the diagnostic spectrum, waiting times and the availability of an integrated waiting list and transplant registry (NLTR). PMID:25959101

    The aim of the present large population-based cohort study is to explore the risk factors of age-related mortality in liver transplant recipients in Taiwan. Basic information and data on medical comorbidities for 2938 patients who received liver transplants between July 1, 1998, and December 31, 2012, were extracted from the National Health Insurance Research Database on the basis of ICD-9-codes. Mortality risks were analyzed after adjusting for preoperative comorbidities and compared among age cohorts. All patients were followed up until the study endpoint or death. This study finally included 2588 adults and 350 children [2068 (70.4%) male and 870 (29.6%) female patients]. The median age at transplantation was 52 (interquartile range, 43–58) years. Recipients were categorized into the following age cohorts: <20 (n = 350, 11.9%), 20–39 (n = 254, 8.6%), 40–59 (n = 1860, 63.3%), and ≥60 (n = 474, 16.1%) years. In the total population, 428 deaths occurred after liver transplantation, and the median follow-up period was 2.85 years (interquartile range, 1.2–5.5 years). Dialysis patients showed the highest risk of mortality irrespective of age. Further, the risk of death increased with an increase in the age at transplantation. Older liver transplant recipients (≥60 years), especially dialysis patients, have a higher mortality rate, possibly because they have more medical comorbidities. Our findings should make clinicians aware of the need for better risk stratification among elderly liver transplantation candidates. PMID:27019189

  6. Non-Alcoholic Fatty Liver Disease and Metabolic Syndrome after Liver Transplant

    Liver transplant is the unique curative therapy for patients with acute liver failure or end-stage liver disease, with or without hepatocellular carcinoma. Increase of body weight, onset of insulin resistance and drug-induced alterations of metabolism are reported in liver transplant recipients. In this context, post-transplant diabetes mellitus, hyperlipidemia, and arterial hypertension can be often diagnosed. Multifactorial illnesses occurring in the post-transplant period represent significant causes of morbidity and mortality. This is especially true for metabolic syndrome. Non-alcoholic steatosis and steatohepatitis are hepatic manifestations of metabolic syndrome and after liver transplant both recurrent and de novo steatosis can be found. Usually, post-transplant steatosis shows an indolent outcome with few cases of fibrosis progression. However, in the post-transplant setting, both metabolic syndrome and steatosis might play a key role in the stratification of morbidity and mortality risk, being commonly associated with cardiovascular disease. The single components of metabolic syndrome can be treated with targeted drugs while lifestyle intervention is the only reasonable therapeutic approach for transplant patients with non-alcoholic steatosis or steatohepatitis.

    CLKT and sequential KALT are decided on a case-by-case basis in children for special indications such as ARPKD or PH1. We report on 21 children who underwent CLKT or KALT at our hospital between 1998 and 2013. Eleven children were diagnosed with PH1 and six with ARPKD. Other diagnosis were Joubert syndrome (n = 1), nephronophthisis (n = 1), CF (n = 1), and hepatocellular carcinoma (n = 1). Children (12 males, nine females) were aged 7.8 ± 6.2 yr (range, 10 months to 18 yr) at time of transplantation. Average wait time was 1.9 ± 0.9 yr (range, four months to 2.3 yr). Fifteen patients received dialysis prior to transplantation. In PH1 patients, four children received CLKT, five received KALT, and two infants have received only an LTx, whereas all six patients with ARPKD received CLKT. In patients with other indications, CLKT was performed in three cases and KALT in one girl. Cumulative 10-yr survival of all 21 patients was 78.4%. At the time of transfer into adult care, 13 patients retained stable liver and kidney function. Regardless the underlying diagnosis, CLKT and KALT can be performed in children with good surgical outcomes and long-term survival. PMID:26341656

    We aimed to determine whether frailty, a validated geriatric construct of increased vulnerability to physiologic stressors, predicts mortality in liver transplant (LT) candidates. Consecutive adult outpatients listed for LT with laboratory MELD≥12 at a single center (97% recruitment rate) underwent 4 frailty assessments: Fried Frailty, Short Physical Performance Battery (SPPB), Activities of Daily Living (ADL), and Instrumental ADL (IADL) scales. Competing risks models associated frailty with wait-list mortality (death/delisting for being too sick for LT). 294 listed LT patients with MELD≥12, median age 60y, and MELD 15 were followed for 12 months. By Fried Frailty score≥3, 17% were frail; 11/51 (22%) of the frail versus 25/243 (10%) of the not frail died/were delisted (p=0.03). Each 1-unit increase in the Fried Frailty score was associated with a 45% (95%CI, 4-202%) increased risk of wait-list mortality adjusted for MELD. Similarly, the adjusted risk of wait-list mortality associated with each 1-unit decrease (i.e., increasing frailty) in the SPPB (HR 1.19, 95%CI 1.07-1.32). Frailty is prevalent in LT candidates. It strongly predicts wait-list mortality, even after adjustment for liver disease severity demonstrating the applicability and importance of the frailty construct in this population. PMID:24935609

    Hepatitis E virus (HEV) infection has been identified as a cause of graft hepatitis in liver transplant recipients. The true frequency and clinical importance of HEV infections after liver transplantations is a matter of debate. It is proposed that consumption of HEV-contaminated undercooked meat is a main source for HEV infections in developed countries--which might also account for some hepatitis E cases after organ transplantation. However, HEV is also transmitted by transfusion of blood products, likely representing a previously underestimated risk particularly for patients in the transplant setting. HEV infection can take chronic courses in immunocompromised individuals, associated in some cases with rapid progression to cirrhosis within 1-2 years of infection. Diagnosis in transplanted patients is based on HEV RNA testing as antibody assays are not sensitive enough. Selection of immunosuppressive drugs is important as different compounds may influence viral replication and the course of liver disease. Ribavirin has antiviral activity against HEV and should be administered for at least three months in chronically infected individuals; however, treatment failure may occur. HEV infections have also been linked to a variety of extrahepatic manifestations both during and after resolution of infection. In this review we summarize the emerging data on hepatitis E with a particular focus on the importance of HEV infections for liver transplant recipients. PMID:25195557

    End-stage liver disease (ESLD) is a leading cause of morbidity and mortality amongst human immunodeficiency virus (HIV)-positive individuals. Chronic hepatitis B and hepatitis C virus (HCV) infection, drug-induced hepatotoxicity related to combined anti-retro-viral therapy, alcohol related liver disease and non-alcohol related fatty liver disease appear to be the leading causes. It is therefore, anticipated that more HIV-positive patients with ESLD will present as potential transplant candidates. HIV infection is no longer a contraindication to liver transplantation. Key transplantation outcomes such as rejection and infection rates as well as medium term graft and patient survival match those seen in the non-HIV infected patients in the absence of co-existing HCV infection. HIV disease does not seem to be negatively impacted by transplantation. However, HIV-HCV co-infection transplant outcomes remain suboptimal due to recurrence. In this article, we review the key challenges faced by this patient cohort in the pre- and post-transplant period. PMID:26604639

    Objectives: Liver transplantation is the treatment of choice for acute and chronic liver failure, for selected cases of tumors, and for conditions resulting from errors in metabolism. This paper reports the experience of a medical center in Latin America. Methods: Were conducted 305 orthotopic liver transplantations on 284 patients between 2004 and 2010. Of these patients, 241 were adults undergoing their first transplantation. Results: The average age of patients was 52 years old, and 62% of the individuals were male. The most common indication was alcoholic cirrhosis. The rate of patient survival after 1 and 5 years was 82 and 72% respectively. The rate of liver graft survival after 1 and 5 years was 78 and 68% respectively. The main cause of death was sepsis. Complications in the hepatic artery were documented for 5% of the patients. Additionally, 14.5% of the patients had complications in the biliary tract. Infections were found in 41% of the individuals. Acute rejection was observed in 30% of the subjects, and chronic rejection in 3%. Conclusion: In conclusion, liver transplantation at our medical center in Colombia offers good mid-term results, with a complication rate similar to that reported by other centers around the world.

    Background—Many patients with haemophilia have developed cirrhosis or hepatocellular carcinoma due to transfusion acquired chronic viral hepatitis. 
Aims—To assess the long term outcome of all haemophilic patients reported to have undergone orthotopic liver transplantation. 
Methods—Transplant centres of patients identified by medical database search were contacted and survival data assessed by Kaplan-Meier analysis. 
Results—Twenty six haemophilic men (median age 46 years, range 5-63 years) underwent orthotopic liver transplantation in 16centres between 1982 and 1996. Indications for transplantation were hepatitis C cirrhosis (69%), hepatitis B with or without C cirrhosis (15%), viral hepatitis related hepatocellular carcinoma (12%), and biliary atresia (4%). Six patients (23%) were infected with human immunodeficiency virus (HIV). Postoperatively, the median time to normal clotting factor levels was 24 hours (range 0-48 hours) and exogenous clotting factors were stopped at a median of 24 hours (range 0-480 hours). Four patients (15%) had bleeding complications. The one and three year survival of HIV positive recipients (67% and 23%) was significantly poorer (p=0.0003) than that of HIV negative recipients (90% and 83%). Coagulopathy was cured in all patients surviving more than 12 days post-transplant. Six of the 20 patients (30%) with hepatitis C cirrhosis pretransplant had evidence of disease recurrence at a mean of nine months post-transplant. 
Conclusions—Hepatitis C cirrhosis is the most common indication for orthotopic liver transplantation in patients with haemophilia. Transplantation results in long term cure of haemophilia but may be complicated by the effects of HIV infection or recurrent viral hepatitis.

    Liver transplantation radically changed the philosophy of hepatology practice, enriched multiple areas of basic science, and had pervasive ripple effects in law, public policy, ethics, and theology. Why organ engraftment was feasible remained enigmatic, however, until the discovery in 1992 of donor leukocyte microchimerism in long-surviving liver, and other kinds of organ recipients. Following this discovery, the leukocyte chimerism-associated mechanisms were elucidated that directly linked organ and bone marrow transplantation and eventually clarified the relationship of transplantation immunology to the immunology of infections, neoplasms, and autoimmune disorders. We describe here how the initially controversial paradigm shift mandated revisions of cherished dogmas. With the fresh insight, the reasons for numerous inexplicable phenomena of transplantation either became obvious or have become susceptible to discriminate experimental testing. The therapeutic implications of the “new immunology” in hepatology and in other medical disciplines, have only begun to be explored. Apart from immunology, physiologic investigations of liver transplantation have resulted in the discovery of growth factors (beginning with insulin) that are involved in the regulation of liver size, ultrastructure, function, and the capacity for regeneration. Such studies have partially explained functional and hormonal relationships of different abdominal organs, and ultimately they led to the cure or palliation by liver transplantation of more than 2 dozen hepatic-based inborn errors of metabolism. Liver transplantation should not be viewed as a purely technologic achievement, but rather as a searchlight whose beams have penetrated the murky mist of the past, and continue to potentially illuminate the future.

    Background/Aims Endoscopic retrograde cholangiopancreatography (ERCP) can be an effective treatment for bile leakage after liver transplantation. We evaluated the efficacy of endoscopic treatment in liver transplantation in patients who developed bile leaks. Methods Forty-two patients who developed bile leaks after liver transplantation were included in the study. If a bile leak was observed on ERCP, a sphincterotomy was performed, and a nasobiliary catheter was then inserted. If a bile leak was accompanied by a bile duct stricture, either the stricture was dilated with balloons, followed by nasobiliary catheter insertion across the bile duct stricture, or endoscopic retrograde biliary drainage was performed. Results In the bile leakage alone group (22 patients), endoscopic treatment was technically successful in 19 (86.4%) and clinically successful in 17 (77.3%) cases. Among the 20 patients with bile leaks with bile duct strictures, endoscopic treatment was technically successful in 13 (65.0%) and clinically successful in 10 (50.0%) cases. Among the 42 patients who underwent ERCP, technical success was achieved in 32 (76.2%) cases and clinical success was achieved in 27 (64.3%) cases. Conclusions ERCP is an effective and safe therapeutic modality for bile leaks after liver transplantation. ERCP should be considered as an initial therapeutic modality in post-liver transplantation patients. PMID:25717048

    Patient: Female, 54 Final Diagnosis: Suprahepatic inferior vena cava anastomosis stricture Symptoms: Ascites • fatigue • lower limb edema • hepatomegaly Medication: — Clinical Procedure: — Specialty: Transplantology • Critical Care Medicine Objective: Unusual clinical course Background: Suprahepatic inferior vena cava anastomosis stricture is an unusual vascular complication after orthotopic liver transplantation with the “piggyback” technique. Clinical manifestations are dependent upon the severity of the stenosis. Portopulmonary hypertension after orthotopic liver transplantation is a complication that carries high mortality due to cardiopulmonary dysfunction. The pathogenesis of pulmonary vascular disorders after orthotopic liver transplantation remains uncertain. Case Report: We report a case of acute right heart pressure overload after surgical correction of the suprahepatic inferior vena cava anastomotic stricture in a 54-year-old woman who had preexisting pulmonary arterial hypertension associated with portal hypertension after orthotopic liver transplantation. Twenty months posttransplantation, she developed fatigue and progressive ascites. On admission, the patient had hepatomegaly, ascites, and lower limb edema. Symptoms in the patient developed gradually over time. Conclusions: Recurrent portal hypertension by vascular complications is a cause of pulmonary arterial hypertension after orthotopic liver transplantation. Clinical manifestations of suprahepatic inferior vena cava anastomotic stenosis are dependent upon their severity. Sildenafil is an effective drug for treatment of pulmonary arterial hyper-tension after portal hypertension by vascular complications. PMID:24046802

    HEHE is a rare neoplasm of vascular origin that occurs in the liver; UNOS reported a favorable outcome after liver transplantation in 110 patients with 1-year and 5-year survival of 80% and 64%. Case Report. A 40-year-old lady presented with a three-month history of right upper abdominal pain with nausea, vomiting, and significant loss of weight associated with scleral icterus and progressive abdominal distension. Examination revealed jaundice, hepatomegaly, and ascites. Serum bilirubin was 26.5 mg/dL and ALP was 552 CT. Abdomen and pelvis showed diffuse infiltrative neoplastic process of the liver with a mass effect and stretching of the hepatic and portal veins, in addition to bile duct dilatation. Viral hepatitis markers were negative and serum alpha fetoprotein was within reference range. Liver biopsy was consistent with HEHE, with positive endothelial markers (CD31, CD34, and factor VIII-related antigen). She underwent living related liver transplantation on June 2013 and was discharged after 20 days with normal liver enzymes. Four months later, she presented with diffuse disease recurrence. Liver biopsy confirmed disease recurrence; she received supportive treatment and unfortunately she died 2 weeks later. Conclusion. HEHE can have rapid and aggressive recurrence after liver transplantation. PMID:27446853

    Simultaneous heart-liver transplantation, although rare, has become more common in the U.S. When the primary organ is a heart or liver, patients receiving an offer for the primary organ automatically receive the second, non-primary organ from that donor. This policy raises issues of equity—i.e. whether liver transplant-alone candidates bypassed by heart-liver recipients are disadvantaged. No prior published analyses have addressed this issue, and few methods have been developed as a means to measure the impact of such allocation policies. We analyzed OPTN match run data from 2007-2013 to determine whether this combined organ allocation policy disadvantages bypassed liver transplant waitlist candidates in a clinically meaningful way. Among 65 heart-liver recipients since May 2007, 42 had substantially higher priority for the heart relative to the liver, and bypassed 268 liver-alone candidates ranked 1-10 on these match runs. Bypassed patients had lower risk of waitlist removal for death or clinical deterioration compared to controls selected by match MELD score (HR: 0.56, 95% CI: 0.40-0.79), and similar risk as controls selected by laboratory MELD score (HR: 0.91, 95% CI: 0.63-1.33) or on match runs of similar graft quality (HR: 0.97, 95% CI: 0.73-1.37). The waiting time from bypass to subsequent transplantation was significantly longer among bypassed candidates versus controls on match runs of similar graft quality (median: 87 (IQR: 27-192) days versus 24 (5-79) days; p<0.001). Although transplant is delayed, liver transplant waitlist candidates bypassed by heart-liver recipients do not have excess mortality compared to three sets of matched controls. These analytic methods serve as a starting point to consider other potential approaches to evaluate the impact of multi-organ transplant allocation policies PMID:25044621

    The case history of a 14-year-old boy with fulminant hepatic failure secondary to non-A, non-B hepatitis who fulfilled selection criteria for orthotopic liver transplantation is described. Two forms of liver support were used (extracorporeal liver assist device and an auxiliary partial orthotopic liver transplantation) to provide additional time to allow spontaneous recovery to occur. During the 66 h of extracorporeal haemoperfusion through the device, haemodynamic stability was maintained along with improvements in serum bilirubin (555 to 381 mumol/l), and international normalized ratio (INR) (3.7 to 2.9). Deterioration in these parameters was observed following cessation of treatment and 10 h later, after a donor liver had become available, an auxiliary transplant was performed. Clinical recovery, though initially slow, was eventually complete, with histopathological and scintigraphic evidence of full liver regeneration at 3 months. Withdrawal of his immunosuppressive drugs began at 6 months and was complete by 14 months after auxiliary transplantation. He has since remained well with normal liver function tests. Temporary liver support may provide additional time for spontaneous recovery of the native liver to occur in selected cases of fulminant hepatic failure, even when criteria are fulfilled for orthotopic liver grafting.

    New-onset diabetes is a frequent complication after solid organ transplantation. Although a number of common factors are associated with the disease, including recipient age, body mass index, hepatitis C infection, and use of immunosuppressive drugs, new-onset diabetes after liver transplantation (NODALT) has the following unique aspects and thus needs to be considered its own entity. First, a liver graft becomes the patient's primary metabolic regulator after liver transplantation, but this would not be the case for kidney or other grafts. The metabolic states, as well as the genetics of the graft, play crucial roles in the development of NODALT. Second, dysfunction of the islets of Langerhans is common in cirrhotic patients and would be exacerbated by immunosuppressive agents, particularly calcineurin inhibitors. On the other hand, minimized immunosuppressive protocols have been widely advocated in liver transplantation because of liver tolerance (immune privilege). Third and last, through the "gut-liver axis," graft function is closely linked to gut microbiota, which is now considered an important metabolic organ and known to independently influence the host's metabolic homeostasis. Liver transplant recipients present with specific gut microbiota that may be prone to trigger metabolic disorders. In this review, we proposed 3 possible sites for the origin of NODALT, which are liver, islets, and gut, to help elucidate the underlying mechanism of NODALT. PMID:26910326

    Candidate selection for liver transplantation presents challenging ethical issues that require balancing the principles of justice and utility. The goal of this study was to assess the opinions of U.S. transplant providers regarding the ways in which controversial medical and psychosocial characteristics influence patient eligibility for liver transplantation. An online, anonymous survey about adult patient characteristics was sent to providers (hepatologists, surgeons, psychiatrists, and social workers) at all 102 active adult liver transplant centers in the United States. A majority of the providers (251/444 or 56.5%) completed the survey. The providers were queried about 8 characteristics, and the 3 that were ranked most controversial were incarceration, marijuana use, and psychiatric diagnoses. Most providers identified a patient age ≥ 80 years (62.7%), a body mass index ≥ 45 kg/m2 (56.6%), and current incarceration with a lifetime sentence (54.7%) as absolute contraindications to liver transplantation. In a multivariate analysis, the identification of absolute contraindications varied significantly with the provider type, the center volume, and the geographical region. Less than half of the providers reported that their centers had written policies regarding most of the characteristics examined. In conclusion, providers differ significantly in their opinions on controversial patient characteristics and transplant contraindications. Along with a paucity of literature data on outcomes, these provider differences may play a role in the fact that many centers do not have formal policies for selecting patients with these characteristics. Evidence-based data on the outcomes of such patients are needed to guide the formation of written policies to better standardize eligibility criteria. PMID:23197388

    Hypothermic machine preservation (HMP) remains investigational in clinical liver transplantation. It is widely used to preserve kidneys for transplantation with improved results over static cold storage (SCS). At our center, we have used HMP in 31 adults receiving extended criteria donor (ECD) livers declined by the originating United Network for Organ Sharing region ("orphan livers"). These cases were compared to ECD SCS cases in a matched cohort study design. Livers were matched for donor age, recipient age, cold ischemic time, donor risk index and Model for End-Stage Liver Disease (MELD) score. HMP was performed for 3-7 h at 4-8 °C using our previously published protocol. Early allograft dysfunction rates were 19% in the HMP group versus 30% in the control group (p = 0.384). One-year patient survival was 84% in the HMP group versus 80% in the SCS group (p = NS). Post hoc analysis revealed significantly less biliary complications in the HMP group versus the SCS group (4 vs. 13, p = 0.016). Mean hospital stay was significantly shorter in the HMP group (13.64 ± 10.9 vs. 20.14 ± 11.12 days in the SCS group, p = 0.001). HMP provided safe and reliable preservation in orphan livers transplanted at our center. PMID:25521639

    Allocation of medical resources, especially resources with absolute scarcity such as organs for transplant, is a difficult task. Medical, surgical, and ethical considerations should be evaluated. In solid organ transplantation, ethics committees are the gate keepers that deal with moral philosophy when moral values are in conflict. Often, no good solution to a dilemma in these medical ethics exists. Our case presents split living liver donation for retransplantation in a mentally disabled girl, with few medical ethics principles at stake. PMID:22081968

    The current standard for liver preservation is limited in duration. Employing a novel subzero preservation technique that includes supercooling and machine perfusion can significantly improve preservation and prolong storage times. By loading rat livers with cryoprotectants to prevent both intra- and extracellular ice formation and protect against hypothermic injury, livers can be cooled to −6 °C without freezing and kept viable for up to 96 hours. Here, we describe the procedures of loading cryoprotectants by means of subnormothermic machine perfusion (SNMP), controlled cooling to a supercooled state, followed by SNMP recovery and orthotopic liver transplantation.

     Hepatic involvement in AL amyloidosis may present as acute liver failure. Historically, liver transplantation in these cases has achieved poor outcomes due to progress of amyloidosis and non-hepatic organ damage. In the era of bortezomib treatment, the prognosis of AL amyloidosis has been markedly improved and may also result in better post-transplant outcomes. We present a case of isolated acute liver failure caused by AL amyloidosis, bridged to transplantation with bortezomib and treated with sequential orthotopic liver transplantation (OLT) and autologous stem cell transplantation. The patient is in stable remission 3 years after OLT. PMID:27236160

    From its inception the success of liver transplantation has been associated with massive blood loss. Massive transfusion is classically defined as > 10 units of red blood cells within 24 h, but describing transfusion rates over a shorter period of time may reduce the potential for survival bias. Both massive haemorrhage and transfusion are associated with increased risk of mortality and morbidity (need for dialysis/surgical site infection) following liver transplantation although causality is difficult to prove due to the observational design of most trials. The blood loss associated with liver transplantation is multifactorial. Portal hypertension secondary to cirrhosis results in extensive collateral circulation, which can bleed during hepatectomy particular if portal pressures are increased. Avoiding volume loading and maintenance of a low central venous pressure together with the use of vasopressors have been shown to reduce blood loss and transfusion during liver transplantation, but may increase the risk of renal impairment post-operatively. Coagulation defects may be present pre-transplant, but haemostasis is often re-balanced due to a deficit in both pro- and anti-coagulation factors. Further derangement of haemostasis may develop in the anhepatic and neohepatic phases due to absent hepatic metabolic function, hyperfibrinolysis and platelet sequestration in the donor liver. Point-of-care tests of coagulation such as the viscoelastic tests rotation thromboelastometry/thromboelastometry allow and more accurate and rapid assessment of these derangements in coagulation and guide the use of factor replacement and antifibrinolytics. Transfusion protocols guided by these tests have been shown to reduce transfusion rates compared with conventional coagulation tests, but have not shown improvements in mortality or morbidity.

    Glycogen storage disease Ib is a rare, inherited metabolic disorder caused by glucose-6-phosphatase translocase deficiency. Its main symptoms are hypoglycemia, hyperlipidemia, neutropenia, hepatomegaly, liver adenomas and short stature. The exact mechanism of short stature in this disease is unclear, the most feasible possibility is that it is caused by impairment of growth-hormone and insulin-like growth factor I axis. Here we report the case of a patient who showed typical symptoms of glycogen storage disease Ib since his infancy, his height being under 1 percentile since then. Later-developed hypothyroidism and hypogonadism have also contributed to his short stature. Hypothyroidism was treated but sexual steroid substitution was not started because of an increased risk of hepatic adenomas. Because he developed hepatic adenoma at the age of 23, he had to undergo orthotopic liver transplantation. At the time of the transplantation his height was 128cm. The transplantation was followed by rapid height growth; our patient's height reached 160.3cm 62months after transplantation. We observed that while his IGF-I level increased, his GH level remained unchanged. During the post-transplantation period we ensured adequate calcium and vitamin D supplementation, leaving hormonal substitution unchanged. According to our knowledge, this is the first report of a rapid height growth as big as 32cm, of an individual over the age of 20, not related to endocrine treatment but liver transplantation.

    Caring for liver transplant patients suffering from chronic hepatitis C virus (HCV) infection is a challenging task for transplant surgeons and primary physicians alike. HCV is the leading cause of liver transplantation in the USA and comes with a myriad of complications that increase morbidity and mortality. This review focuses on patient follow-up, spanning from before the liver transplant occurs to the patient’s long-term health. Pretransplant, both donor and recipient variables, must be carefully chosen to ensure optimal surgical success. Risk factors must be identified and HCV viral load must be reduced to a minimum. In addition to standard transplant complications, HCV patients suffer from additional problems, such as fibrosing cholestatic hepatitis and widespread viremia. Physicians must focus on the balance of immunosuppressive and antiviral medications, while considering possible side effects from these potent drugs. Over the years following surgery, physicians must identify any signs of failing liver health, as HCV-positive patients have an increased risk for cirrhosis and certain life-threatening malignancies.

    Background Auxiliary partial orthotopic liver transplantation is an alternative technique for the treatment of patients with fulminant hepatic failure and metabolic liver disease. It provides temporary support of liver function until sufficient regeneration of the native liver. Pediatric patients have a long life expectancy and are best candidates to benefit from the interruption of antirejection treatment. Description of case A 4-year-old boy underwent auxiliary partial orthotopic liver transplantation for fulminant hepatic failure using a cadaveric left lateral segment of liver. One year after auxiliary partial orthotopic liver transplantation, the patient’s native liver was determined to be completely normal and he was doing well. The patient was then gradually weaned from the immunosuppression over the course of one year. The graft was undetectable on follow-up computerized tomography performed before complete cessation of immunosuppression, leading to the diagnosis of “vanishing graft syndrome”. Conclusion Graft atrophy commonly occurs after auxiliary partial orthotopic liver transplantation due to cessation of antirejection therapy. But to our knowledge, complete graft disappearance is a rare occurrence reported in the English literature. Timing for withdrawal of the immunosuppression is an important decision to be made in this technique. Hippokratia 2015; 19 (3): 274-277.

    Hepatitis C virus (HCV) reinfects liver allografts in transplant recipients by replicating immediately after transplantation, causing a rapid increase in blood serum HCV RNA levels. We evaluated dynamic changes in the viral genetic complexity after HCV reinfection of the graft liver; we also identified the characteristics of replicating HCV clones using a massively parallel ultradeep sequencing technique to determine the full-genome HCV sequences in the liver and serum specimens of five transplant recipients with genotype 1b HCV infection before and after liver transplantation. The recipients showed extremely high genetic heterogeneity before transplantation, and the HCV population makeup was not significantly different between the liver and blood serum specimens of the individuals. Viral quasispecies complexity in serum was significantly lower after liver transplantation than before it, suggesting that certain HCV clones selectively proliferated after transplantation. Defective HCV clones lacking the structural region of the HCV genome did not increase in number, and full-genome HCV clones selectively increased in number immediately after liver transplantation. A re-increase in the same defective clone existing before transplantation was detected 22 months after transplantation in one patient. Ultradeep sequencing technology revealed that the genetic heterogeneity of HCV was reduced after liver transplantation. Dynamic changes in defective HCV clones after liver transplantation indicate that these clones have important roles in the HCV life cycle. PMID:23985907

    If not promptly recognized and treated, herpes simplex virus (HSV) hepatitis is associated with a high mortality. A patient transplanted for primary sclerosing cholangitis required, 4 years later, a colectomy for a steroid-resistant flare of ulcerative colitis. He subsequently developed fever, with genital and oral ulcerations. He was hospitalized for diabetic decompensation with massive elevation of serum aminotransferases. Examination revealed vesicles on the hands. Liver biopsy showed Cowdry type B inclusions. Therapy with acyclovir was immediately initiated and the patient recovered. This case illustrates the diagnostic importance of mucocutaneous lesions in the assessment of complications after liver transplantation. PMID:14614611

    Recent findings in the pathophysiology and monitoring of hemostasis in patients with end stage liver disease have major impact on coagulation management during liver transplantation. There is increasing evidence, that the changes in both coagulation factors and platelet count regularly observed in patients with liver cirrhosis cannot be interpreted as a reliable indicator of diffuse bleeding risk. Instead, a differentiated view on hemostasis has led to the concept of a rebalanced coagulation system: While it is important to recognize that procoagulant factors are reduced in liver cirrhosis, it is also evident that synthesis of anticoagulant factors and fibrinolytic proteins produced in the liver is also diminished. Similarly, the decreased platelet count may be counterbalanced by increased platelet aggregability caused by highly active von Willebrand multimeres. The coagulation system is therefor stated to be rebalanced. While under normal “unstressed” conditions diffuse bleeding is rarely observed, however both diffuse bleeding or thrombus formation may occur when compensation mechanisms are exhausted. While most patients presenting for liver transplantation have severe cirrhosis, liver function and thus production of pro- and anticoagulant factors can be preserved especially in cholestatic liver disease. During liver transplantation, profound changes in the hemostasis system can occur. Surgical bleeding can lead to diffuse bleeding as coagulation factors and platelets are already reduced. Ischemia and tissue trauma can lead to alterations of hemostasis comparable to trauma induced coagulopathy. A further common disturbance often starting with the reperfusion of the transplanted organ is hyperfibrinolysis which can eventually precipitate complete consumption of fibrinogen and an endogenous heparinization by glycocalyx shedding. Moreover, thrombotic events in liver transplantations are not uncommon and contribute to increased mortality. Besides conventional

    ABSTRACT Liver transplantation (LT) is the treatment of choice for patients with end-stage liver disease (ESLD). Chronic liver disease due to many causes is prevalent in a significant percentage of the Bangladeshi population. Until recently, liver transplantation facilities were not available, and ESLD patients were dying without treatment. Liver transplantation is a complex procedure that requires integrated and organized approach by a multidisciplinary team. The initiation of liver transplantation in Bangladesh has faced many difficulties. These difficulties have been encountered and overcome in phases. We have successfully performed the first two living-donor liver transplantations (LDLTs) in Bangladesh. The recipient of the first LDLT was a 42-year man with cryptogenic cirrhosis, and the second one was a male of 35 years, suffering from HBV cirrhosis. Both the recipients and donors are doing well and relishing the prospect of a normal life. These two successful liver transplantations are milestones in the development of liver transplantation services in Bangladesh. PMID:25895203

    Research is scarce regarding patients' experiences, feelings and thoughts the first 4 weeks after liver transplantation. Most research involving patients with a liver transplant are conducted several months, or even years, after the transplantation. The aim of this study is to present results from research interviews that took place post-transplant while patients still were in hospital. The design is explorative and hermeneutic. Fifteen patients were interviewed 3-5 weeks after transplantation. The results are presented in the following themes: (i) general contentment with the hospital stay, (ii) physical discomfort, (iii) dreams, nightmares and hallucinations, (iv) Comedowns experienced during rejection of the transplant and (v) Other psychological/mental reactions. A major result from our study is patients' own descriptions of comedowns experienced during rejection of the transplant, and the seemingly little consolation and support the patients received. Another major result is patients' own descriptions of dreams, nightmares and hallucinations, which are not fully described from the patients' own perspective while still in hospital. PMID:21812799

    The age of liver donors has been increasing in the past several years because of a donor shortage. In the United States, 33% of donors are age 50 years or older, as are more than 50% in some European countries. The impact of donor age on liver transplantation (LT) has been analyzed in several studies with contradictory conclusions. Nevertheless, recent analyses of the largest databases demonstrate that having an older donor is a risk factor for graft failure. Donor age is included as a risk factor in the more relevant graft survival scores, such as the Donor Risk Index, donor age and Model for End-stage Liver Disease, Survival Outcomes Following Liver Transplantation, and the Balance of Risk. The use of old donors is related to an increased rate of biliary complications and hepatitis C virus-related graft failure. Although liver function does not seem to be significantly affected by age, the incidence of several liver diseases increases with age, and the capacity of the liver to manage or overcome liver diseases or external injuries decreases. In this paper, the importance of age in LT outcomes, the role of donor age as a risk factor, and the influence of aging on liver regeneration are reviewed. PMID:27275089

    Living-donor liver transplantation has become a standard and effective treatment for end stage liver disease patients. As a result of remarkable progress in immunosuppressive drugs, surgical device, anesthetics, and appropriate perioperative management, liver-transplanted patients may experience fewer complications, shorter length of ICU stay, and a better overall outcome. However, unexpected perioperative complications remain substantial. Therefore, we take care in several points in perioperative period. First, we should appropriately evaluate general preoperative conditions, such as coagulopathy, ascites, respiratory and renal function. Second, we need to maintain hemodynamic stabilization, electrolyte balance, correction of coagulopathy and prevention of portal hypertention during operation. And third, in postoperative period we should perform strict monitoring and focus on infection prophylaxis, early weaning from mechanical ventilation, appropriate administration of fluid and transfusion, maintaining renal function and preservation of graft function. Appropriate knowledge and understanding of perioperative management in liver transplantation are required to improve patient's outcome. Furthermore, it is important for performing liver transplantation to boost mutual understanding and trust in the medical team including health-care providers. PMID:24864574

    The scarcity of ideal liver grafts for orthotopic liver transplantation (OLT) has led transplant teams to investigate other sources of grafts in order to augment the donor liver pool. One way to get more liver grafts is to use marginal donors, a not well-defined group which includes mainly donors > 60 years, donors with hypernatremia or macrosteatosis > 30%, donors with hepatitis C virus or hepatitis B virus positive serologies, cold ischemia time > 12 h, non-heart-beating donors, and grafts from split-livers or living-related donations. Perhaps the most practical and frequent measure to increase the liver pool, and thus to reduce waiting list mortality, is to use older livers. In the past years the results of OLT with old livers have improved, mainly due to better selection and maintenance of donors, improvements in surgical techniques in donors and recipients, and intra- and post-OLT management. At the present time, sexagenarian livers are generally accepted, but there still exists some controversy regarding the use of septuagenarian and octogenarian liver grafts. The aim of this paper is to briefly review the aging process of the liver and reported experiences using old livers for OLT. Fundamentally, the series of septuagenarian and octogenarian livers will be addressed to see if there is a limit to using these aged grafts. PMID:25152573

    Hepatocellular carcinoma (HCC) is one of the few malignant tumours often treated without prior histological confirmation (in the patient with cirrhosis). Contrast-enhanced cross-sectional imaging is frequently diagnostic of HCC with a high degree of accuracy. However, on occasion, a liver biopsy is required, a complication of which can be needle-track metastasis. We present the case of a 57-year-old man who had previously undergone a liver transplant; he was found to have abdominal wall metastasis at the site of a prior percutaneous biopsy. This is the second case until now date of needle-track metastasis that presented following liver transplantation. PMID:24913074

    Work over several decades has laid solid foundations for the advancement of liver cell therapy. To date liver cell therapy in people has taken the form of hepatocyte transplantation for metabolic disorders with a hepatic basis, and for acute or chronic liver failure. Although clinical trials using various types of autologous cells have been implemented to promote liver regeneration or reduce liver fibrosis, clear evidence of therapeutic benefits have so far been lacking. Cell types that have shown efficacy in preclinical models include hepatocytes, liver sinusoidal endothelial cells, mesenchymal stem cells, endothelial progenitor cells, and macrophages. However, positive results in animal models have not always translated through to successful clinical therapies and more realistic preclinical models need to be developed. Studies defining the optimal repopulation by transplanted cells, including routes of cell transplantation, superior engraftment and proliferation of transplanted cells, as well as optimal immunosuppression regimens are required. Tissue engineering approaches to transplant cells in extrahepatic locations have also been proposed. The derivation of hepatocytes from pluripotent or reprogrammed cells raises hope that donor organ and cell shortages could be overcome in the future. Critical hurdles to be overcome include the production of hepatocytes from pluripotent cells with equal functional capacity to primary hepatocytes and long-term phenotypic stability in vivo.

    Purpose of review To review the experience to date and unique challenges associated with liver transplantation in hepatitis C virus (HCV)/HIV-coinfected patients. Recent findings The prevalence of cirrhosis and hepatocellular carcinoma is rising among HIV-infected individuals. With careful patient selection and in the absence of HCV infection, HIV-infected and HIV-uninfected liver transplant recipients have comparable posttransplant outcomes. However, in the presence of HCV infection, patient and graft survival are significantly poorer in HIV-infected recipients, who have a higher risk of aggressive HCV recurrence, acute rejection, sepsis, and multiorgan failure. Outcomes may be improved with careful recipient and donor selection and with the availability of new highly potent all-oral HCV direct acting antivirals (DAAs). Although all-oral DAAs have not been evaluated in HIV/HCV-coinfected transplant patients, HIV does not adversely impact treatment success in nontransplant populations. Therefore, there is great hope that HCV can be successful eradicated in HIV/HCV-coinfected transplant patients and will result in improved outcomes. Careful attention to drug–drug interactions with HIV antiretroviral agents, DAAs, and posttransplant immunosuppressants is required. Summary Liver transplant outcomes are poorer in HIV/HCV-coinfected recipients compared with those with HCV-monoinfection. The new HCV DAAs offer tremendous potential to improve outcomes in this challenging population. PMID:25944240

  9. Liver transplantation as a management of hepatocellular carcinoma

    Hepatocellular carcinoma (HCC) is one of the most common cancers worldwide and has a poor prognosis if untreated. It is ranked the third among the causes of cancer-related death. There are multiple etiologic factors that can lead to HCC. Screening for early HCC is challenging due to the lack of well specific biomarkers. However, early diagnosis through successful screening is very important to provide cure rate. Liver transplantation (LT) did not gain wide acceptance until the mid-1980s, after the effective immunosuppression with cyclosporine became available. Orthotopic LT is the best therapeutic option for early, unresectable HCC. It is limited by both, graft shortage and the need for appropriate patient selection. It provides both, the removal of tumor and the remaining cirrhotic liver. In Milan, a prospective cohort study defined restrictive selection criteria known as Milan criteria (MC) that led to superior survival for transplant patients in comparison with any other previous experience with transplantation or other options for HCC. When transplantation occurs within the established MC, the outcomes are similar to those for nonmalignant liver disease after transplantation. The shortage of organs from deceased donors has led to the problems of long waiting times and dropouts. This has led to the adoption of extended criteria by many centers. Several measures have been taken to solve these problems including prioritization of patients with HCC, use of pretransplant adjuvant treatment, and living donor LT. PMID:26052380

    This study aimed to establish a rat liver transplantation model with a steatotic donor liver after cardiac death, reflecting clinical conditions. Rats were fed a high-fat diet for 8 weeks to establish the fatty liver model. This model simulates liver steatosis caused by various factors before clinical donation after cardiac death. A pneumothorax was created in the donor rat to induce hypoxia and cardiac arrest before incising the liver. This simulated the processes of hypoxia and cardiac arrest caused by withdrawal of treatment in actual clinical situations. The harvested cardiac death donor liver was then transplanted using the Kamada technique. Donor operative time was 45.7 ± 4.2 min; cardiac arrest time, 9 ± 0.8 min; recipient surgery time, 40.3 ± 4.9 min; and no-liver time, 15 ± 2.5 min. Of 40 liver-transplanted rats, 2 died within 24 h, with a surgical success rate of 95%. The transaminase levels on post-transplantation days 1, 3, 5, and 7 were 835.4 ± 71.33 U/L, 1334.5 ± 102.13 U/L, 536.4 ± 65.52 U/L, and 218.2 ± 36.77 U/L, respectively. This rat liver transplantation model with a steatotic donor liver after cardiac death could improve the simulation of the pathophysiological processes of clinical donation after cardiac death, and could be used as a reliable and stable animal model.

    We retrospectively collected the characteristics of 80 consecutive adult patients with biologically confirmed measles during a recent epidemic in France. We report on the frequency and severity of liver involvement in adult patients with measles. In our experience, measles in adults was not severe and hepatitis was not correlated with severe cases or bacterial infection. Therefore, hepatitis should be regarded as a usual symptom rather than a complication of measles infection in adults. PMID:23938044

    Graft versus host disease (GVHD) is an uncommon complication following liver transplantation. In the present case report, a 53-year-old male hepatitis B virus carrier was diagnosed with primary liver cancer with post-hepatitis cirrhosis. Preoperative cytomegalovirus (CMV), Epstein-Barr virus, coxsackievirus, herpes simplex virus and autoimmune antibody series were negative. Preoperative human leukocyte antigen type was also negative. Following classic orthotropic liver transplantation, postoperative treatment included immunosuppression therapy, infection protection, anti-human immunodeficiency virus therapy and CMV infection protection therapy. Chemotherapy was initiated at day 16 following surgery. At day 26 following the transplantation, the patient developed a fever of unknown cause, and a scattered red rash was observed behind the left ear and on the neck. The patient presented with a fever of unknown cause, rash, symptoms of the digestive tract, leukocytopenia and pancytopenia. A diagnosis of GVHD was confirmed following a skin biopsy. Symptomatic therapies, including antivirals, anti-anaphylaxis drugs and steroids were administered. However, the patient succumbed to infection, acute respiratory distress syndrome and multiple organ failure at day 46 following surgery. Therefore, an effective therapeutic strategy for the treatment of GVHD following liver transplantation is yet to be established, and further research is required prior to such a regimen being developed.

    Currently in Brazil, living donor liver transplantation (LDLT) represents 8.5% of liver transplantation (LT), being the majority pediatric one. Up to now, according to Brazilian Organ Transplantation Association (ABTO) annual report, 2,086 procedures have been done nationwide, most of them in southeast and south regions. Based on national centers reports, biliary complication is the most common recipient postoperative complication (14.5-20.6%), followed by hepatic artery thrombosis (3.1-10.7%) and portal vein thrombosis (2.3-9.1%). Patient and graft overall 5-y survival correspond to 76% and 74%, respectively. Regarding the donor, morbidity rate ranges from 12.4% to 28.3%, with a national mortality rate of 0.14%. In conclusion, Brazilian LDLT programs enhance international experience that this is a feasible and safe procedure, as well as an excellent alternative strategy to overcome organs shortage.

    Paediatric orthotopic liver transplant recipients may develop chronic hepatitis after surgery. To investigate the role of hepatitis C virus in this pathology a cohort of 249 paediatric orthotopic liver transplant recipients was studied. Sixteen children (6.4%) were found to have chronic hepatitis C virus hepatitis after orthotopic liver transplantation. All but one of them had serum transaminase values which were persistently raised two to eight times the upper limit of normal. Thirteen were positive for both serology and serum hepatitis C virus RNA. Serum hepatitis C virus RNA detection occurred five to 33 months before hepatitis C virus antibodies. Liver tissue hepatitis C virus RNA and hepatitis C virus core antigen were detected in five. In one patient, tissue hepatitis C virus core antigen was detected when other tests for hepatitis C were negative. Two patients had positive human cytomegalovirus serum antibodies and RNA before transplantation. Although serum hepatitis C virus RNA was not detected after transplantation, serum enzyme immunosorbent assay and tissue core antigen were still detectable in both patients. In another child, serum hepatitis C virus RNA was positive and hepatitis C virus core antigen was found on a liver biopsy specimen but antihepatitis C virus antibodies were negative as well as liver hepatitis C virus RNA. No patient developed severe liver disease or cirrhosis during a follow up of up to 72 months. It is concluded that hepatitis C virus is a significant cause of morbidity after paediatric orthotopic liver transplantation. Diagnosis cannot rely on serological testing only. The patients remained stable on follow up, but longer prospective histological studies remain necessary to establish prognosis. PMID:7618905

  17. CRRT Regional Anticoagulation Using Citrate in the Liver Failure and Liver Transplant Population.

    2016-01-01

    Regional citrate for continuous renal replacement therapy (CRRT) use in patients with liver failure or post-liver transplant has been considered a contraindication because of the risk of citrate toxicity development. Regional citrate has the benefit of decreased bleeding risks over systemic anticoagulation; therefore, it is of great benefit to the coagulopathic and surgical populations. This article analyzes current empiric data and compares with a case study specifically related to liver failure, liver transplant, and CRRT use. We found that the use of a total serum to ionized calcium ratio was much more reliable in measuring liver function than liver enzyme figures. This when paired with a citrate-reduction guideline based on serum to ionized calcium ratios provided effective, early management of citrate toxicity. Using new measurements to calculate liver metabolism of citrate and using a new citrate-reducing guideline allow the bedside practitioner to use regional citrate anticoagulation in patients with liver failure and liver transplant who require CRRT.

    APOLT is a suitable technique of liver transplantation in patients with ALF and some types of MLD. Portal venous steal is a problem with this procedure that leads to graft dysfunction and failure. Modulation of the portal flow to the graft and native liver can help in preventing this problem. We discuss the pathophysiology of this complication, review available literature regarding its management, and describe our results using the technique of graded hemiportal banding to achieve adequate perfusion for the graft and native liver.

    Background. We aimed to assess incidentally discovered hepatocellular carcinoma (iHCC) over time and to compare outcome to preoperatively diagnosed hepatocellular carcinoma (pdHCC) and nontumor liver transplants. Methods. We studied adults transplanted with a follow-up of at least one year. Patients were divided into 3 groups according to diagnosis of hepatocellular carcinoma. Results. Between 1990 and 2010, 887 adults were transplanted. Among them, 121 patients (13.6%) had pdHCC and 32 patients (3.6%) had iHCC; frequency of iHCC decreased markedly over years, in parallel with significant increase in pdHCC. Between 1990 and 1995, 120 patients had liver transplants, 4 (3.3%) of them had iHCC, and only 3 (2.5%) had pdHCC, while in the last 5 years, 263 patients were transplanted, 7 (0.03%) of them had iHCC, and 66 (25.1%) had pdHCC (P < 0.001). There was no significant difference between groups regarding patient survival; 5-year survival was 74%, 75.5%, and 77.3% in iHCC, pdHCC, and non-HCC groups, respectively (P = 0.702). Patients with iHCC had no recurrences after transplant, while pdHCC patients experienced 17 recurrences (15.3%) (P = 0.016). Conclusions. iHCC has significantly decreased despite steady increase in number of transplants for hepatocellular carcinoma. Patients with iHCC had excellent outcomes with no tumor recurrence and survival comparable to pdHCC. PMID:27403337

    Surgical advances have allowed for the development of split liver transplantation, providing two recipients with the opportunity to potentially benefit from one donated liver by splitting the liver into two usable parts. Although current data suggest that the splitting of livers provides overall benefit to the liver-recipient population, relatively low numbers of livers are actually split in the United Kingdom. This article addresses the question of whether ethical concerns are posing an unnecessary barrier to further increasing the number of life-saving transplantations. Recognizing that an important aspect of exploring these concerns is gaining insight into how transplant staff and patients regard splitting livers, the article presents the findings of a qualitative study examining the views of senior transplant staff and liver transplant patients in the UK and uses these to inform a commentary on the ethical issues relating to split liver transplantation.

    AIM: To analyze differences in patients’ clinical course, we compared two regimes of either preemptive therapy or prophylaxis after liver transplantation. METHODS: This retrospective study was reviewed and approved by the institutional review board of the University of Leipzig. Cytomegalovirus (CMV) prophylaxis with valganciclovir hydrochloride for liver transplant recipients was replaced by a preemptive strategy in October 2009. We retrospectively compared liver transplant recipients 2 years before and after October 2009. During the first period, all patients received valganciclovir daily. During the second period all patients included in the analysis were treated following a preemptive strategy. Outcomes included one year survival and therapeutic intervention due to CMV viremia or infection. RESULTS: Between 2007 and 2010 n = 226 patients underwent liver transplantation in our center. n = 55 patients were D+/R- high risk recipients and were excluded from further analysis. A further 43 patients had to be excluded since CMV prophylaxis/preemptive strategy was not followed although there was no clinical reason for the deviation. Of the remaining 128 patients whose data were analyzed, 60 received prophylaxis and 68 were treated following a preemptive strategy. The difference in overall mortality was not significant, nor was it significant for one-year mortality where it was 10% (95%CI: 8%-28%, P = 0.31) higher for the preemptive group. No significant differences in blood count abnormalities or the incidence of sepsis and infections were observed other than CMV. In total, 19 patients (14.7%) received ganciclovir due to CMV viremia and/or infections. Patients who were treated according to the preemptive algorithm had a significantly higher rate risk of therapeutic intervention with ganciclovir [n = 16 (23.5%) vs n = 3 (4.9%), P = 0.003)]. CONCLUSION: These data suggest that CMV prophylaxis is superior to a preemptive strategy in patients undergoing liver

    Background Although liver transplantation is the last resort for treating end stage liver diseases, this medical procedure is not available for all needful patients because of inadequate organ supply. Therefore, guidelines have been developed by medical experts to regulate the process. Some professionals believe that medical criteria are inadequate for organ allocation in all situations and may not secure fairness of organ allocation. Objectives The current study has been designed to identify decision criteria about allocation of donated liver to potential recipients from public points of view. Patients and Methods This is a qualitative study that was conducted through individual interviews and Focus Group Discussions. Individual interviews were conducted among patients’ companions and nurses in one of the two liver transplant centers in Iran. Group discussions were conducted among groups of ordinary people who had not dealt previously with the subject. Data was analyzed by Thematic Analysis method. Results Most of the participants in this study believe that in equal medical conditions, some individual and societal criteria could be used to prioritize patients for receiving donated livers. The criteria include psychological acceptance, ability to pay post-operative care costs, being breadwinner of the family, family support, being socially valued, ability to be instructed, lack of mental disorders, young age of the recipient, being on waiting list for a long time, lack of patient’s role in causing the illness, first time transplant recipient, critical medical condition, high success rate of transplantation, lack of concurrent medical illnesses, not being an inmate at the time of receiving transplant, and bearing Iranian nationality. Conclusions Taking public opinion into consideration may smooth the process of organ allocation to needful patients with equal medical conditions. It seems that considering these viewpoints in drafting organ allocation guidelines

    Burra, Patrizia; Rodriguez-Castro, Kryssia I

    2015-01-01

    De novo neoplasms account for almost 30% of deaths 10 years after liver transplantation and are the most common cause of mortality in patients surviving at least 1 year after transplant. The risk of malignancy is two to four times higher in transplant recipients than in an age- and sex-matched population, and cancer is expected to surpass cardiovascular complications as the primary cause of death in transplanted patients within the next 2 decades. Since exposure to immunosuppression is associated with an increased frequency of developing neoplasm, long-term immunosuppression should be therefore minimized. Promising results in the prevention of hepatocellular carcinoma (HCC) recurrence have been reported with the use of mTOR inhibitors including everolimus and sirolimus and the ongoing open-label prospective randomized controlled SILVER. Study will provide more information on whether sirolimus-containing vs mTOR-inhibitor-free immunosuppression is more efficacious in reducing HCC recurrence. PMID:26269665

    The present case report describes the diagnosis and treatment of a patient with veno-occlusive disease (VOD) following liver transplantation. Combining the clinical data and relevant literature, the study aimed to consider the causes of VOD following liver transplantation, and the pathogenesis, clinical diagnosis and auxiliary examination features of VOD. A 42-year-old man who had a long history of taking traditional Chinese medicine (essential components unknown) underwent an orthotropic liver transplantation on January 14, 2011, due to small venous occlusion disease of the liver. The patient was treated with tacrolimus as an antirejection therapy following the surgery, and gradually developed right upper quadrant pain and fatigue. The examination results were consistent with the diagnostic standards for VOD. Following treatment with methylprednisolone, the patient was treated with alprostadil and Danhong injections. Forty days later, the patient’s total bilirubin (TBIL) level was observed to have decreased significantly, the liver function had returned to normal and the ascites had decreased, but had not completely disappeared. The patient then underwent a transjugular intrahepatic portosystemic shunt (TIPS) procedure, following which the ascites were shown to have completely disappeared. PMID:24348779

    2009-01-01

    Intestinal Failure is a permanent loss of digestive and absorptive functions as a consequence of short bowel syndrome and/or other primary intestinal conditions. Patients with intestinal failure (IF) require long term parenteral nutrition to survive. The only alternative to parenteral nutrition is intestinal transplantation which still entails high mortality. Children with intestinal failure on parenteral nutrition may develop liver failure (LF), as a consequence of central line infections and other conditions. In children with both irreversible IF and LF a combined transplantation is generally considered. Despite low survival rate, combined liver/intestine transplantation is associated to better intestinal graft survival and lower incidence and severity of rejection compared to isolated small bowel transplantation. Recently, isolated liver transplantation was proposed in children with IF and LF. This procedure may have a higher survival probability compared to isolated intestinal transplant, it may allow progressive weaning from PN in children in whom the remnant intestine has the potential for adaptation and offer a timely solution in children for whom intestinal graft is not immediately available. This innovative approach may prove a better option compared to combined transplantation in both the short and long term PMID:19754937

    2010-01-01

    Hepatitis C is a leading etiology of liver cancer and cause for liver transplantation. Although new therapies have improved the rates of sustained response, a large proportion of patients (~50%) fail to respond to antiviral treatment, thus remaining at risk for disease progression. While chimpanzees have been used to study HCV biology and treatments, their cost is quite high and their use is strictly regulated; indeed, the NIH no longer supports the breeding of chimpanzees for study. The development of HCV therapies has been hindered by the relative paucity of small animal models to study HCV pathogenesis. This review presents the strengths of the human liver transplant, highlighting the advances derived from this model, including insights into viral kinetics and quasispecies, viral receptor binding and entry, innate and adaptive immunity. Moreover, consideration is made of current and emerging antiviral therapeutic approaches based on translational research results. PMID:19877210

    In 2002, the Italian Ministry of Health (IMH) launched a formal call for health research programs within the Research and Development (R&D) Policy. In this context, the research program "Innovative Strategies to Expand Cadaveric Donor Pool for Liver Transplantation" (SITF Project) has been proposed. The SITF Project has been formally approved by IMH as a 2-year research program included in the R&D Policy. The main goals of the SITF Project are to improve matching criteria for split liver transplantation (SLT) in both pediatric and adult recipients, to promote an increase of the SLT/full- size liver transplantation ratio at the national level, and, especially, to establish shared criteria for SLT in 2 adult recipients. The original executive plan of the SITF Project prefigured the participation of both the Italian transplantation centers with more advanced experience in the field of SLT, and institutional partnership, such as Nord Italia Transplant (NITp) and Italian National Transplant Center. A first Web public area concerning the SITF Project has been activated, as well as a reserved Web area with the aim to share cadaveric donors and patients in the waiting lists between Operative Units involved in the research program. For this objective, the first version Oracle-based database able to perform an automatic matching between a single cadaveric donor and 2 potential adult recipients has been released at the beginning of 2005. The SITF Project represents a new approach in the management of SLT for 2 adult recipients in Italy and a model for a functional network between Italian transplantation centers. PMID:16182693

    The role of liver transplantation (LT) in acute liver failure (ALF) complicated by severe acute pancreatitis is still unclear. We here report a case of deceased-donor LT for idiopathic ALF accompanied by severe acute pancreatitis. A 58-year-old man with no history of liver disease presented with idiopathic ALF and acute pancreatitis. After careful consideration, he received a liver from a deceased donor. Following surgery, the patient's liver function rapidly reverted to normal level and the acute pancreatitis simultaneously subsided. The patient later developed a pancreatic pseudocyst, which was treated successfully with combination interventional radiology. LT can be considered for ALF associated with severe acute pancreatitis if there is no clinical evidence of an absolute contraindication for organ transplantation, such as systemic or local infection. Moreover, we recommend a close follow-up by ultrasonography to allow early detection and treatment of pancreatic pseudocysts following surgery. PMID:27600056

    Hepatic tumors often recur in the liver after surgical resection. Postoperative radiotherapy (RT) could improve survival, but curative RT may induce delayed life-threatening radiation-induced liver damage. Because RT inhibits liver regeneration, we hypothesized that unirradiated, transplanted hepatocytes would proliferate preferentially in a partially resected and irradiated liver, providing metabolic support. We subjected F344 rats to hepatic RT and partial hepatectomy with/without a single intrasplenic, syngeneic hepatocyte transplantation. Hepatocyte transplantation ameliorated radiation-induced liver damage and improved survival of rats receiving RT after partial hepatectomy. We further demonstrated that transplanted hepatocytes extensively repopulate and function in a heavily irradiated rat liver. PMID:10606225

    The authors report the case of a patient who presented with small bowel obstruction while awaiting liver transplant for Child-Pugh class C cirrhosis. He underwent emergency liver transplant with resection of the small bowel after the obstruction did not improve with conservative management. The authors believe this is the first case of successful emergency liver transplant with resection of the small bowel in a patient with decompensated Child-Pugh class C liver cirrhosis and strangulated umbilical hernia. This case suggests the possibility of improved outcomes of emergency hernia repair in patients with liver cirrhosis when small bowel resection is combined with liver transplant. PMID:23190414

    Liver transplantation (LT) is the only curative option for patients with familial amyloid polyneuropathy (FAP) at present. Twenty patients with FAP underwent LT between May 1998 and June 2007. Transthyretin mutations included predominantly the Val30Met mutation but also 10 other mutations. Seven patients received a pacemaker prior to LT, and because of impairment of mechanical cardiac function, 4 combined heart-liver transplants were performed, 1 simultaneously and 3 sequentially. The first patient, who underwent simultaneous transplantation, died. Seven patients died after LT, with 5 dying within the first year after transplantation. The causes of death were cardiac complications (4 patients), infections (2 patients), and malnutrition (1 patient). One-year survival was 75.0%, and 5-year survival was 64.2%. Gly47Glu and Leu12Pro mutations showed an aggressive clinical manifestation: 2 patients with the Gly47Glu mutation, the youngest patients of all the non-Val30Met patients, suffered from severe cardiac symptoms leading to death despite LT. Two siblings with the Leu12Pro mutation, who presented only with grand mal seizures, died after LT because of sepsis. In conclusion, the clinical course in patients with FAP is very variable. Cardiac symptoms occurred predominantly in patients with non-Val30Met mutations and prompted combined heart-liver transplantation in 4 patients. Although early LT in Val30Met is indicated in order to halt the typical symptoms of polyneuropathy, additional complications occurring predominantly with other mutations may prevail and lead to life-threatening complications or a fatal outcome. Combined heart-liver transplantation should be considered in patients with restrictive cardiomyopathy. PMID:20209591

    Acute liver failure (ALF) is a reversible disorder that is associated with an abrupt loss of hepatic mass, rapidly progressive encephalopathy and devastating complications. Despite its high mortality, an emergency liver transplantation nowadays forms an integral part in ALF management and has substantially improved the outcomes of ALF. Here, we report the case of a 32-year-old female patient who was admitted with grade IV hepatic encephalopathy (coma) following drug-induced ALF. We performed an emergency auxiliary partial orthotopic liver transplantation with a “high risk” graft (liver macrovesicular steatosis approximately 40%) from a living donor. The patient was discharged on postoperative day 57 with normal liver function. Weaning from immunosuppression was achieved 9 mo after transplantation. A follow-up using CT scan showed a remarkable increase in native liver volume and gradual loss of the graft. More than 6 years after the transplantation, the female now has a 4-year-old child and has returned to work full-time without any neurological sequelae. PMID:26855552

    Hepatopulmonary syndrome (HPS) is present in 10-32% of chronic liver disease patients, carries a poor prognosis and is treatable by liver transplantation (LT). Previous reports have shown high LT mortality in HPS and severe HPS (arterial oxygen (PaO(2)) < or =50 mmHg). We reviewed outcomes in HPS patients who received LT between 2002 and 2008 at two transplant centers supported by a dedicated HPS clinic. We assessed mortality, complications and gas exchange in 21 HPS patients (mean age 51 years, MELD score 14), including 11/21 (52%) with severe HPS and 5/21 (24%) with living donor LT (median follow-up 20.2 months after LT). Overall mortality was 1/21 (5%); mortality in severe HPS was 1/11 (9%). Peritransplant hypoxemic respiratory failure occurred in 5/21 (24%), biliary complications in 8/21 (38%) and bleeding or vascular complications in 6/21 (29%). Oxygenation improved in all 19 patients in whom PaO(2) or SaO(2) were recorded. PaO(2) increased from 52.2 +/- 13.2 to 90.3 +/- 11.5 mmHg (room air) (p < 0.0001) (12 patients); a higher baseline macroaggregated albumin shunt fraction predicted a lower rate of postoperative improvement (p = 0.045) (7 patients). Liver transplant survival in HPS and severe HPS was higher than previously demonstrated. Severity of HPS should not be the basis for transplant refusal. PMID:19775311

  16. CMV infection, diagnosis and antiviral strategies after liver transplantation.

    Cytomegalovirus (CMV) is a significant pathogen complicating the post-transplant course of organ recipients. In liver transplant patients, the febrile clinical illness caused by CMV may be associated with end-organ disease, such as hepatitis or infection of the gastrointestinal tract. In addition to direct effects, CMV may have indirect effects including the risk of other infections or graft rejection. Recently, major advances in the management of CMV infection have been achieved through the development of new diagnostic techniques and antiviral strategies to prevent CMV disease. Quantitative nucleic acid testing to monitor viral load is now commonly used to diagnose and guide the treatment of CMV infections. The standardization of the testing, however, needs to be improved. There are two main strategies to prevent CMV disease after liver transplantation: prophylaxis and pre-emptive therapy. Both strategies are effective, but also have disadvantages. The disadvantages of prophylaxis include prolonged drug exposure, the development of resistance and, most of all, the development of delayed and late-onset CMV disease. On the other hand, the pre-emptive strategy is based on frequent laboratory monitoring of viral loads, and some patients may develop symptomatic infection before the diagnosis of CMV. This overview summarizes the current status of CMV in liver transplantation. PMID:19619175

    Hepatic ischemia/reperfusion (I/R) injury is a side effect of major liver surgery that often cannot be avoided. Prolonged periods of ischemia put a metabolic strain on hepatocytes and limit the tolerable ischemia and preservation times during liver resection and transplantation, respectively. In both surgical settings, temporarily lowering the metabolic demand of the organ by reducing organ temperature effectively counteracts the negative consequences of an ischemic insult. Despite its routine use, the application of liver cooling is predicated on an incomplete understanding of the underlying protective mechanisms, which has limited a uniform and widespread implementation of liver-cooling techniques. This review therefore addresses how hypothermia-induced hypometabolism modulates hepatocyte metabolism during ischemia and thereby reduces hepatic I/R injury. The mechanisms underlying hypothermia-mediated reduction in energy expenditure during ischemia and the attenuation of mitochondrial production of reactive oxygen species during early reperfusion are described. It is further addressed how hypothermia suppresses the sterile hepatic I/R immune response and preserves the metabolic functionality of hepatocytes. Lastly, a summary of the clinical status quo of the use of liver cooling for liver resection and transplantation is provided. PMID:26552060

    University of Wisconsin (UW) solution has been known as the standard solution for liver graft preservation. Alternative preservation solutions have been used in liver transplantation, such as histidine-tryptophan-ketoglutarate (HTK) and Celsior solution. Institut Georges Lopez-1 (IGL-1) is a new preservation solution with lower potassium and lower viscosity than UW solution that has recently been used in liver transplant. Data from 178 patients who received transplants from August 2008 to June 2013 at Hospital Santa Isabel, Blumenau, Brazil, were analyzed. All patients received grafts from brain death donors. In November 2011 we started to use IGL-1 as an alternate preservation solution. Therefore, 53 patients using IGL-1 preserved grafts were compared to 125 using HTK solution. The donor age in the HTK group ranged from 11-77 years, with a mean of 43.4 ± 4.8. In the IGL-1 group donor age ranged from 9-62 years, with a mean of 35.8 ± 4.5. Cold ischemia time in the HTK group ranged from 85-1145 minutes, mean 443.5 ± 183.5 minutes. In the IGL-1 group, cold ischemia time ranged from 85-670 minutes, mean 329.3 ± 134.8 minutes. The overall operative mortality rate was 14% (25 patients); in the HTK group, 14.4% (18 patients); and in the IGL-1 group, 13.4% (7 patients). One graft in the HTK group presented with primary non-function (PNF), 0.7%; there were none in the IGL-1 group. In our study, IGL-1 has been shown to be safe to use as a preservation solution for liver transplantation. Early post-transplant graft function was comparable to that observed with HTK solution, although a tendency for lower alanine aminotransferase levels was noticed. IGL-1 has been shown to be safe, cost efficient, and an effective preservation solution. PMID:25131043

    Right-lobe living donor liver transplantation (RL-LDLT) is a common method devised in order to fulfill the demands of donor organ shortage in adult patients with end-stage liver diseases. However, biliary complications remain as the "Achilles' heel" of RL-LDLT, with wide variety of incidence among transplantation centers. Patients with biliary complications after RL-LDLT may have similar clinical presentations to those with other causes of graft dysfunction. Therefore, radiological evaluation plays a key role for differential diagnosis of such complications. In this article, we discuss the various methods of biliary reconstruction and imaging findings of common and uncommon biliary complications in recipients of RL-LDLT. PMID:25972371

    Introduction Accurate assessment of the impact of donor quality on liver transplant (LT) costs has been limited by the lack of a large, multicenter study of detailed clinical and economic data. Methods A novel, retrospective database linking information from the University HealthSystem Consortium and the OPTN registry was analyzed using multivariate regression to determine the relationship between donor quality (assessed through the Donor Risk Index (DRI)), recipient illness severity, and total inpatient costs (transplant and all readmissions) for 1 year following LT. Results Cost data were available for 9,059 LT recipients. Increasing MELD score, higher DRI, simultaneous liver kidney transplant, female gender and prior liver transplant were associated with increasing cost of LT (P<0.05). MELD and DRI interact to synergistically increase the cost of LT (P<0.05). Donors in the highest DRI quartile added close to $12,000 to the cost of transplantation and nearly $22,000 to post-transplant costs in comparison to the lowest risk donors. Among the individual components of the DRI, donation after cardiac death (increased $20,769 vs. brain dead donors) had the greatest impact on transplant costs. Overall one year costs were increased in older donors, minority donors, nationally shared organs, and those with cold ischemic times 7–13 hours (p<0.05 for all) Conclusion Donor quality, as measured by the DRI, is an independent predictor of LT costs in the perioperative and post-operative periods. Centers in highly competitive regions who transplant higher MELD patients with high DRI livers may be particularly affected by the synergistic impact of these factors. PMID:21384505

    AIM: To determine utility of transplant liver biopsy in evaluating efficacy of percutaneous transluminal angioplasty (PTA) for hepatic venous obstruction (HVOO). METHODS: Adult liver transplant patients treated with PTA for HVOO (2003-2013) at a single institution were reviewed for pre/post-PTA imaging findings, manometry (gradient with right atrium), presence of HVOO on pre-PTA and post-PTA early and late biopsy (EB and LB, < or > 60 d after PTA), and clinical outcome, defined as good (no clinical issues, non-HVOO-related death) or poor (surgical correction, recurrent HVOO, or HVOO-related death). RESULTS: Fifteen patients meeting inclusion criteria underwent 21 PTA, 658 ± 1293 d after transplant. In procedures with pre-PTA biopsy (n = 19), no difference was seen between pre-PTA gradient in 13/19 procedures with HVOO on biopsy and 6/19 procedures without HVOO (8 ± 2.4 mmHg vs 6.8 ± 4.3 mmHg; P = 0.35). Post-PTA, 10/21 livers had EB (29 ± 21 d) and 9/21 livers had LB (153 ± 81 d). On clinical follow-up (392 ± 773 d), HVOO on LB resulted in poor outcomes and absence of HVOO on LB resulted good outcomes. Patients with HVOO on EB (3/7 good, 4/7 poor) and no HVOO on EB (2/3 good, 1/3 poor) had mixed outcomes. CONCLUSION: Negative liver biopsy greater than 60 d after PTA accurately identifies patients with good clinical outcomes. PMID:26207170

    Since 1989, all pediatric liver transplants in Switzerland are centralized at the University Hospitals of Geneva (HUG). Approximately 125 children have received transplants since then, and their survival rate is greater than 90% - one of the highest in Europe. Maximizing the chances of success requires that patients understand and comply with follow-up treatment. The KidsETransplant project aims at helping the child - and his family - to better understand his health situation, to have access to shared resources and to be able to better communicate with healthcare professionals and other patients.

    Background and Aims. Biliary complications are the most frequent complications after common liver surgeries. In this study, accuracy of hepatobiliary scintigraphy (HBS) and impact of hyperbilirubinemia were evaluated. Methods. Between November 2007 and February 2016, 131 patients underwent hepatobiliary scintigraphy after having liver surgery. 39 patients with 42 scans after LTX (n = 13) or hepatic resection (n = 26) were evaluated in the study; 27 were male, with mean age 60 years. The subjects underwent hepatobiliary scintigraphy with Tc-99m labeled Mebrofenin. The results were compared to ERCP as gold standard performed within one month after HBS. We calculated sensitivity, specificity, PPV, and NPV. We compared LTX patients to patients with other liver surgeries. Furthermore the influence of hyperbilirubinemia on HBS scans was evaluated. Results. HBS always provided the correct diagnosis in cases of bile leak in the liver-resected group (14/14). Overall diagnostic accuracy was 76% (19/25) in this group and 54% (7/13) in the LTX group. False negative (FN) diagnoses occurred more often among LTX patients (p = 0.011). Hyperbilirubinemia (>5 mg/dL) significantly influenced the excretion function of the liver, prolonging HBS's time-activity-curve (p = 0.001). Conclusions. Hepatobiliary scintigraphy is a reliable tool to detect biliary complications, but reduced accuracy must be considered after LTX. PMID:27563464

    Abstract Biliary strictures and bile leaks account for the majority of biliary complications after living donor liver transplantation (LDLT). The aim of this study was to examine differences in biliary complications after adult LDLTs were performed by an experienced senior surgeon and an inexperienced junior surgeon. Surgeries included bile duct reconstruction after adult LDLT using a right liver graft, and risk factors for biliary stricture were identified. We retrospectively reviewed the medical records of 136 patients who underwent LDLT in order to identify patients who developed biliary complications. The senior surgeon performed 102 surgeries and the junior surgeon performed 34 surgeries. The proportion of patients with biliary stricture was similar between the senior and the junior surgeons (27.5% vs 26.5%; P = 0.911). However, the incidence of biliary leakage was higher in patients of the junior surgeon than in those of the senior surgeon (23.5% vs 2.9%; P = 0.001). The frequency of percutaneous drainage was also higher for the junior surgeon than the senior surgeon because of the junior surgeon’s high leakage rate of the drainage. When the junior surgeon performed bile duct anastomosis, biliary leakage occurred in 7 patients between the 11th and 20th cases. However, biliary leakage occurred in only 1 case thereafter. Bile duct reconstruction performed by beginner surgeons in LDLT using right lobe grafts should be cautiously monitored and observed by a senior surgeon until an inexperienced junior surgeon has performed at least 20 cases, because of the high incidence of biliary leakage related to surgeon’s inexperience in bile duct reconstructions in LDLT.

    Liver transplantation (LT) recipients in the United States have low rates of paid employment, making some eligible for Medicaid public health insurance after transplant. We test whether recent expansions of Medicaid eligibility increased Medicaid enrollment and insurance coverage in this population. Patients of ages 18-59 years receiving first-time LTs in 2009-2013 were identified in the United Network for Organ Sharing registry and stratified according to insurance at transplantation (private versus Medicaid/Medicare). Posttransplant insurance status was assessed through June 2015. Difference-in-difference multivariate competing-risks models stratified on state of residence estimated effects of Medicaid expansion on Medicaid enrollment or use of uninsured care after LT. Of 12,837 patients meeting inclusion criteria, 6554 (51%) lived in a state that expanded Medicaid eligibility. Medicaid participation after LT was more common in Medicaid-expansion states (25%) compared to nonexpansion states (19%; P < 0.001). Multivariate analysis of 7279 patients with private insurance at transplantation demonstrated that after the effective date of Medicaid expansion (January 1, 2014), the hazard of posttransplant Medicaid enrollment increased in states participating in Medicaid expansion (hazard ratio [HR] = 1.5; 95% confidence interval [CI] = 1.1-2.0; P = 0.01), but not in states opting out of Medicaid expansion (HR = 0.8; 95% CI = 0.5-1.3; P = 0.37), controlling for individual characteristics and time-invariant state-level factors. No effects of Medicaid expansion on the use of posttransplant uninsured care were found, regardless of private or government insurance status at transplantation. Medicaid expansion increased posttransplant Medicaid enrollment among patients who had private insurance at transplantation, but it did not improve overall access to health insurance among LT recipients.

    Introduction The aim of the study was to assess the diagnostic accuracy of procalcitonin (PCT) as a marker for complications and as a prognostic factor for mortality after liver transplantation. Material and methods Liver transplant patients between January 2007 and April 2011 were prospectively included in the study. Procalcitonin serum concentration was recorded before, 6 h after reperfusion and then daily. Postoperative clinical course was prospectively analyzed from admission to discharge. Main surgical data such as operating procedure, type of reperfusion, operating and ischemic times, high urgency (HU) status and MELD score at the time of transplantation were also recorded. Results Sixteen patients with initial PCT > 5 ng/ml suffered ≥ 1 complication (p = 0.03). However, there was no association between the level of the 1st peak PCT and the further postoperative course or the occurrence of complications. Patients in whom a 2nd PCT peak occurred had a significantly higher risk for a complicated course, for a complicated sepsis course and for mortality (p < 0.0001). Warm ischemic time over 58 min, operating time over 389 min and HU status were significant independent factors for a complicated postoperative course (p < 0.001, p < 0.001 and p = 0.03 respectively). Conclusions Based on our results, we believe that PCT course and the occurrence of a 2nd peak seem to possess important diagnostic and prognostic power in the post-transplant setting after liver transplantation.

    Background Hepatopulmonary syndrome is formed by a triad of liver disease, intrapulmonary vascular dilatation and changes in blood gases. This condition is present in 4-32% of patients with cirrhosis. Aim To analyze the blood gas changes data of patients in liver-transplant waiting list. Method Clinical data of 279 patients in liver transplantation waiting list in May 2013 were studied. Overall patient was analyzed by the demographic aspects, laboratorial and image findings on exams that determine lung disease (hypoxemia) in these cirrhotic patients. The mean values and standard deviations were used to examine normally distributed variables. Results There was a high prevalence of male patients (68%); the mean age was 51(±5,89) years, and the predominant reason for listing was hepatitis C cirrhosis. The MELD score mean was 16±5,89, without prioritization or special situation. The most common blood type was O in 129 cases (46%) and the mean of body max index was 25,94±4,58. Regarding arterial blood gas tests was observed 214 patients with PaO2 <90 mmHg, 80 with PaO2 <80 mmHg and 39 with PaO2 <50 mmHg. In relation to O2 saturation, 50 patients had <90%, 33 <80% and 10 <50%. Conclusion Was observed a high rate of hypoxemia in patients on waiting list liver transplant. Due to the high severity and morbidity, is suggested better monitoring and therapeutic support to hypoxemic patients on liver transplant waiting list. PMID:24676301

    Recurrence of hepatitis C virus (HCV) after living donor liver transplantation was investigated using technetium-99m- diethylenetriaminepentaacetic acid-galactosyl human serum albumin (Tc-99m-GSA) liver scintigraphy. Four patients with decompensated cirrhosis due to HCV infection were retrospectively reviewed in this study. Scintigraphy was performed to determine the hepatic uptake ratio of the tracer corrected for disappearance from the blood, as well as the maximal removal rate of the tracer by hepatocytes, as parameters of hepatic functional reserve. In all patients, serum HCV ribonucleic acid (RNA) was detected 3 months after transplantation. The corrected hepatic uptake ratio and removal rate showed little change after transplantation in two patients without the recurrence of HCV infection. In another two patients, these levels were decreased at 3 months after transplantation. In one patient, recurrent HCV infection was diagnosed by confirmatory histologic examination at 12 months after transplantation. In the other patient, both levels declined further at 8 months. Although treatment was initiated with a combination of interferon plus ribavirin, this patient died of progressive hepatic failure. In conclusion, a decrease in scintigraphic parameters at 3 months after transplantation suggests recurrent HCV infection affecting the graft. Tc-99m-GSA liver scintigraphy is a useful noninvasive method for evaluating graft functional reserve. PMID:16977504

    Tc-NGA is a new liver imaging agent which binds to hepatic binding protein (HBP), a hepatocyte-specific membrane receptor. The purpose of the present study was to evaluate the potential role of Tc-NGA imaging in liver transplantation. The molar Tc-NGA dose was standardized according to patient weight (0.7 nmole/kg). After a 30 minute dynamic imaging study (5 mCi, IV), kinetic analysis of time activity data (heart, liver), provided values for receptor concentration, (HBP), and hepatic blood flow, Q. Eleven Tc-NGA imaging studies were performed in transplant candidates and 22 studies were performed in seven transplant recipients. Preservation damage was manifested by diffuse patchiness in tracer distribution which resolved during the following two weeks. Histologically proven, localized hepatic infarcts were demonstrated in three recipients. Lobar infarction was demonstrated in one recipient. Hepatic regeneration was later demonstrated in this patient after hepatic lobectomy. Hepatic blood flow was markedly decreased in the early postoperative period, but improved with time. Increased (HBP) was demonstrated with regeneration. Markedly decreased (HBP) and Q were obtained in several candidates who died awaiting transplantation. These studies indicate that TC-NGA liver imaging provides a valuable new means for: (1) evaluation of preservation damage, (2) early demonstration of hepatic infarction, (3) evaluation of hepatic rejection, and (4) selection of patients for hepatic transplantation.

    The British Transplantation Society Guidelines for Living Donor Liver Transplantation was published in July 2015 and is the first national guideline in the field of living donor liver transplantation. The guideline aims to review the evidence relating to the evaluation process of both recipient and donor candidates; address the moral and ethical issues surrounding the procedure; outline the technical aspects of the procedure, including the middle hepatic vein controversy and the "small for size syndrome"; review donor and recipient outcomes and complications including donor mortality; and examine evidence relating to the advantages and disadvantages of living donor liver transplantation. In line with previous guidelines published by the BTS, the guideline has used the Grading of Recommendations Assessment, Development and Evaluation system to rate the strength of evidence and recommendations. This article summarizes the Statements of Recommendation contained in the guideline, which provide a framework for the delivery of living liver donation in the United Kingdom and may be of wide international interest. It is recommended that the full guideline document is consulted for details of the relevant references and evidence base.

    Progressive familial intrahepatic cholestasis (PFIC) is a constellation of inherited disorders that result in the impairment of bile flow through the liver that predominantly affects children. The accumulation of bile results in progressive liver damage, and if left untreated leads to end stage liver disease and death. Patients often present with worsening jaundice and pruritis within the first few years of life. Many of these patients will progress to end stage liver disease and require liver transplantation. The role and timing of liver transplantation still remains debated especially in the management of PFIC1. In those patients who are appropriately selected, liver transplantation offers an excellent survival benefit. Appropriate timing and selection of patients for liver transplantation will be discussed, and the short and long term management of patients post liver transplantation will also be described.

    Kakati, Bobby; Seetharam, Anil

    2014-01-01

    Chronic Hepatitis C (HCV) infection is the leading indication for orthotopic liver transplantation and recurrence is nearly universal. Chronic HCV infection is frequently established through evasion of the innate immune system. Priming of adaptive immune responses modulate the severity and rate of fibrosis progression. Those with demonstrable viremia entering the transplant period uniformly suffer recurrence post-transplant. Progression to cirrhosis is accelerated post-transplant secondary to systemic immunosuppression. In addition, a number of factors, including donor, host, and viral characteristics, influence severity and rate of fibrosis progression. Interferon-based therapy, the previous standard of care, in those with advanced cirrhosis or post-transplant has been limited by a number of issues. These include a relative lack of efficacy and poor tolerability with higher incidence of infection and anemia. Recently, approval of direct acting antivirals have ushered in a new era in HCV therapeutics and have applicability in these special populations. Their use immediately prior to or post-transplant is expected to improve both morbidity and mortality. PMID:26355427

    Post-liver transplant patients require lifelong immunosuppressive care and monitoring. Computerized alerts can aid laboratory monitoring, but it is unknown how the distribution of alerts changes over time. We describe the changes over time of the distribution of computerized alerts for laboratory monitoring of post-liver transplant immunosuppressive care. Data were collected for post-liver transplant patients transplanted and managed at Intermountain Healthcare between 2005 and 2012. Alerts were analyzed based on year triggered, time since transplantation, hospitalization status, alert type, action taken (accepted or rejected), reason given for the action taken, and narrative comments. Alerts for overdue laboratory testing became more prevalent as time since transplantation increased. There is an increased need to support monitoring for overdue laboratory testing as the time since transplantation increases. Alerts should support providers as they monitor the evolving needs of post-transplant patients over time. We identify opportunities for improving laboratory monitoring of post-liver transplant patients. PMID:26958291

    Liver transplantation has become the best and most durable treatment for both acute and chronic liver disease. Over 1400 liver transplants have been performed at the Ochsner Clinic since the first successful transplant in 1987. Since its inception, the program has gone through several changes and advancements and has become one of the largest liver transplant programs in the United States. We have helped evolve steroid sparing immunosuppression and the use of extended criteria, donor organs. Establishment of criteria for the selection of recipients for re-transplantation has resulted in better than expected short and long-term results. Our center has faced the challenge of Hurricane Katrina and overcome it. We have improved steadily in both outcomes and transplants performed. The Ochnser Clinic Liver Transplant program will continue to improve access and outcomes for all patients with liver disease. PMID:23721014

    The Israeli population does not meet its transplantation organ needs. Therefore, liver transplantation (LTX) candidates are sometimes transported to centers abroad. We aimed to assess the demographic and clinical issues concerning this policy. Records of all candidates transported (2000-2004) were retrospectively reviewed. Data included etiology, disease severity, outcome, distances traveled and destinations, and medical complication arising en route. Forty-three candidates were transported overseas: 12 patients with fulminant hepatic failure (FHF) and 31 with cirrhosis. Average MELD score was 19.94, and the APACHE II score for patients with FHF was 20.5. Destinations included the United States, Colombia, Belgium, Germany, China, and Italy. Average distance traveled was 4,660 miles. Two patients were intubated and sedated during flight. All patients safely reached their destinations: 8 died prior to transplantation, 5 died after transplantation, 3 are awaiting transplantation, 3 recovered spontaneously, and the rest successfully underwent transplantation and returned home. In conclusion, our results suggest that long-distance transportation of patients awaiting liver transplantation is safe and technically feasible provided precaution measures are taken. Therefore, allocation regions may be broadened to include larger and more distant populations. PMID:15915481

    An increasing number of patients older than 65 years are referred for and have access to organ transplantation, and an increasing number of older adults are donating organs. Although short-term outcomes are similar in older versus younger transplant recipients, older donor or recipient age is associated with inferior long-term outcomes. However, age is often a proxy for other factors that might predict poor outcomes more strongly and better identify patients at risk for adverse events. Approaches to transplantation in older adults vary across programs, but despite recent gains in access and the increased use of marginal organs, older patients remain less likely than other groups to receive a transplant, and those who do are highly selected. Moreover, few studies have addressed geriatric issues in transplant patient selection or management, or the implications on health span and disability when patients age to late life with a transplanted organ. This paper summarizes a recent trans-disciplinary workshop held by ASP, in collaboration with NHLBI, NIA, NIAID, NIDDK and AGS, to address issues related to kidney, liver, lung, or heart transplantation in older adults and to propose a research agenda in these areas.

    Alcoholic liver disease encompasses a broad spectrum of diseases ranging from steatosis steatohepatitis, fibrosis, and cirrhosis to hepatocellular carcinoma. Forty-four per cent of all deaths from cirrhosis are attributed to alcohol. Alcoholic liver disease is the second most common diagnosis among patients undergoing liver transplantation (LT). The vast majority of transplant programmes (85%) require 6 mo of abstinence prior to transplantation; commonly referred to as the "6-mo rule". Both in the case of progressive end-stage liver disease (ESLD) and in the case of severe acute alcoholic hepatitis (AAH), not responding to medical therapy, there is a lack of evidence to support a 6-mo sobriety period. It is necessary to identify other risk factors that could be associated with the resumption of alcohol drinking. The "Group of Italian Regions" suggests that: in a case of ESLD with model for end-stage liver disease < 19 a 6-mo abstinence period is required; in a case of ESLD, a 3-mo sober period before LT may be more ideal than a 6-mo period, in selected patients; and in a case of severe AAH, not responding to medical therapies (up to 70% of patients die within 6 mo), LT is mandatory, even without achieving abstinence. The multidisciplinary transplant team must include an addiction specialist/hepato-alcohologist. Patients have to participate in self-help groups. PMID:25356027

    Orthotopic liver transplantation had been performed in 1983 in a now 40-year-old woman in the terminal stage of posthepatitis liver cirrhosis with recurrent oesophageal bleedings and precoma from complete liver-cell failure. She became pregnant in 1988 while under immunosuppression with cyclosporin (2.1-2.7 mg/kg body-weight) and prednisolone (5 or 7.5 mg daily in rotation). Pregnancy proceeded without complication and there were no side effects from cyclosporin. After premature membrane rupture in the 39th week of pregnancy uterine inertia developed during oxytocin stimulation of contractions, and caesarean section was performed. The female infant was normally developed without any malformations. Liver, kidney and adrenal functions were normal, as was haemopoiesis. But possible late sequelae of cyclosporin treatment in the child cannot as yet be assessed because of the short follow-up. PMID:2338057

    2015-03-01

    Hereditary transthyretin amyloidosis (ATTR) is a rare worldwide autosomal dominant disease caused by the systemic deposition of an amyloidogenic variant of transthyretin (TTR), which is usually derived from a single amino acid substitution in the TTR gene. More than 100 mutations have been described, with V30M being the most prevalent. Each variant has a different involvement, although peripheral neuropathy and cardiomyopathy are the most common. Orthotopic liver transplantation (OLT) was implemented as the inaugural disease-modifying therapy because the liver produces the circulating unstable TTR. In this review, we focus on the results and long-term outcomes of OLT for ATTR after more than 2063 procedures and 23 years of experience. After successful OLT, neuropathy and organ impairment are not usually reversed, and in some cases, the disease progresses. The overall 5-year survival rate is approximately 100% for V30M patients and 59% for non-ATTR V30M patients. Cardiac-related death and septicemia are the main causes of mortality. Lower survival is related to malnutrition, a longer duration of disease, cardiomyopathy, and a later onset (particularly for males). Deposits, which are composed of a mixture of truncated and full-length TTR (type A) fibrils, have been associated with posttransplant myocardial dysfunction. A higher incidence of early hepatic artery thrombosis of the graft has also been documented for these patients. Liver-kidney/heart transplantation is an alternative for patients with advanced renal disease or heart failure. The sequential procedure, in which ATTR livers are reused in patients with liver disease, reveals that neuropathy in the recipient may appear as soon as 6 years after OLT, and ATTR deposits may appear even earlier. Long-term results of trials with amyloid protein stabilizers or disrupters, silencing RNA, and antisense oligonucleotides will highlight the value and limitations of liver transplantation.

    Sirolimus is a promising immune suppressive agent, with the potential to reduce calcineurin inhibitor associated nephrotoxicity, halt progression of chronic rejection and prevent tumor proliferation. The aim of this study was to review the experience using sirolimus in pediatric liver transplant recipients at a single center. Database and medical charts of all pediatric liver transplant recipients receiving sirolimus at the Hospital for Sick Children in Toronto were reviewed. Eight patients received sirolimus between October, 2000 and September, 2002. Indications for using sirolimus were post-transplant lymphoproliferative disease (PTLD) (n = 6) and hepatoblastoma (n = 2). Two patients with PTLD concurrently had renal impairment and chronic rejection. Sirolimus dosages ranged between 1.5 and 5 mg once daily. Median duration of follow-up was 17 months. Persistently elevated liver transaminase levels in the two children with chronic rejection decreased during sirolimus therapy. Recurrence of PTLD occurred in one patient. Two patients were diagnosed with acute cellular rejection after transition to maintenance sirolimus monotherapy. Resolution of adverse effects including mouth sores (n = 3), leg swelling (n = 2) and hyperlipidemia (n = 3) occurred either spontaneously or with dose reduction. Sirolimus was discontinued in four patients because of persisting bone marrow suppression, interstitial pneumonitis, life-threatening sepsis and refractory diarrhea. Children with PTLD or hepatoblastoma may benefit from immune suppression with sirolimus after liver transplantation. Further multi-center, prospective, randomized controlled trials will be instrumental to further the knowledge of long-term efficacy, safety and tolerability of sirolimus for selected children following liver transplantation.

    The use of herbal medications is increasing significantly in the UK and there is a perception that herbal preparations are without adverse effects. This case report highlights the potential risks of black cohosh, which is one of the most commonly used herbal products. This is a case report of a 60-year-old Caucasian lady who presented with subacute liver failure secondary to taking black cohosh. This was further confirmed by liver biopsy and she subsequently deteriorated and underwent liver transplantation. Available evidence supports an association between black cohosh and risk of hepatotoxicity. In current literature, there have only been four previously reported cases of hepatotoxicity associated with black cohosh, which required liver transplantation. We submit that our patient represents the fifth case. We recommend that patients taking this supplement should have close monitoring of their hepatic function, especially in the presence of other risk factors. PMID:23833086

    Previous work has shown that adult mouse hepatocytes can divide at least 18 times in vivo. To test whether this represents the upper limit of their regenerative capacity, we performed serial transplantation of hepatocytes in the fumarylacetoacetate hydrolase deficiency murine model of liver repopulation. Hepatocytes from adult donors were serially transplanted in limiting numbers six times and resulted in complete repopulation during each cycle. This corresponds to a minimal number of 69 cell doublings or a 7.3 x 10(20)-fold expansion. No evidence for abnormal liver function or altered hepatic architecture was found in repopulated animals. We conclude that a fraction of adult mouse hepatocytes have growth potential similar to that of hematopoietic stem cells. Images Figure 1 Figure 2 Figure 3 Figure 4 Figure 5 PMID:9358753

    The number of children affected by the hepatitis C virus (HCV) in the United States is estimated to be between 23000 to 46000. The projected medical cost for children with HCV in the United States is $199-366 million over the next decade. The implementation of routine screening of blood supply has virtually eliminated transmission via transfusion and vertical transmission is now the most common mode of infection in children. Infections acquired during infancy are more likely to spontaneously resolve and fibrosis of the liver tends to increase with age suggesting slow progressive histologic injury. Anti-viral treatment may be warranted in children with persistently elevated liver enzymes or with significant fibrosis on liver biopsy. Current standard of care includes weekly pegylated interferon and ribavirin twice daily. Predictors of high sustained viral response include genotype 2 and 3 and low viral load in children with genotype 1 (< 600000 IU/mL). Phase 1 and 2 trials with triple therapy (interferon, ribavirin, and a protease inhibitor) are ongoing. Triple therapy is associated with a significantly higher rate of sustained virologic response (> 90%). Only 34 pediatric patients were transplanted with hepatitis C between January 2008 and April 2013. The majority of pediatric patients were born prior to universal screening of blood products and, as of June 2013, there are only two pediatric patients awaiting liver transplantation for end-stage liver disease secondary to hepatitis C. Pediatric survival rates post-transplant are excellent but graft survivals are noticeably reduced compared to adults (73.73% for pediatric patients at one year compared to 87.69% in adult patients). New safe and effective antiviral therapies for recurrent HCV should help increase graft survival. PMID:25170212

    Mycobacterium abscessus is a rare cause of human infection and is difficult to diagnose unless it is suspected. A 45-year-old woman underwent deceased donor liver transplantation following which she developed non-healing surgical site infection, which did not resolve with routine antibiotics for 2 months. The scraping of the wound revealed M abscessus infection. Definitive identification of this species of mycobacterium was possible by its growth characteristics on culture and reverse line blot hybridisation assay. She was treated with clarithromycin and cotrimaxazole as per sensitivity and showed complete recovery from the infection within 6 weeks of starting the drugs, which were continued for 6 months. We believe that this is the first documented case of surgical site infection by M abscessus in a liver transplant recipient. PMID:22778369

    Propionic acidemia (PA) is an autosomal recessive disorder of metabolism due to deficiency of the enzyme propionyl-CoA carboxylase (PCC) that converts propionyl-CoA to methylmalonyl-CoA with the help of the cofactor biotin inside the mitochondria. The resultant accumulation of propionyl-CoA causes severe hyperammonaemia and life-threatening metabolic acidosis. Based on the positive outcomes, liver transplantation is now recommended for individuals with recurrent episodes of hyperammonaemia or acidosis that is not adequately controlled with appropriate medical therapies. We report anaesthetic management of two children with PA for liver transplantation at our institution. It is essential for the anaesthesiologist, caring for these individuals to be familiar with the manifestations of the disease, the triggers for decompensation and management of an acute episode.

    Quality of life (QoL) after deceased donor liver transplantation is increasingly recognized as a major outcome parameter. We reviewed recent publications in this rapidly evolving field in order to summarize recent achievements in the field and to define opportunities and perspectives for research and improvement of patient care. QoL does improve after liver transplantation according to a typical pattern. During the first year, there is a significant improvement in QoL. After one year, the improvement does stabilise and tends to decline slightly. In addition to the physical condition, different psychological parameters (such as depression, anxiety, sexual function) and sociodemographic elements (professional state, sex, marital state) seem to impact QoL. Opportunities for further research are the use of dedicated questionnaires and identification of influencing factors for QoL. PMID:27366301

    Immunosuppression in organ transplantation was revolutionary for its time, but technological and population changes cast new light on its use. First, metabolic syndrome (MS) is increasing as a public health issue, concomitantly increasing as an issue for post-orthotopic liver transplantation patients; yet the medications regularly used for immunosuppression contribute to dysfunctional metabolism. Current mainstay immunosuppression involves the use of calcineurin inhibitors; these are potent, but nonspecifically disrupt intracellular signaling in such a way as to exacerbate the impact of MS on the liver. Second, the impacts of acute cellular rejection and malignancy are reviewed in terms of their severity and possible interactions with immunosuppressive medications. Finally, immunosuppressive agents must be considered in terms of new developments in hepatitis C virus treatment, which undercut what used to be inevitable viral recurrence. Overall, while traditional immunosuppressive agents remain the most used, the specific side-effect profiles of all immunosuppressants must be weighed in light of the individual patient.

    Objectives To examine the techniques and the outcome of liver transplantation with maximal conservation of blood products and to analyze the potential benefits or drawbacks of blood conservation and salvage techniques. Design Case series survey. Setting Tertiary care, major university teaching hospital. Patients and Methods Four patients with religious objections to blood transfusions who were selected on the basis of restrictive criteria that would lower their risk for fatal hemorrhage, including coagulopathy, a thrombosed splanchnic venous system requiring extensive reconstruction, active bleeding, and associated medical complications. All patients were pretreated with erythropoietin to increase production of red blood cells. All operations were performed at the same institution, with a 36-month follow-up. Interventions Orthotopic liver transplantation that used blood salvage, plateletpheresis, and autotransfusion and the withholding of the use of human blood products with the exception of albumin. Main Outcome Measures Survival and postoperative complications, with the effectiveness of erythropoietin and plateletpheresis as secondary measures. Results All patients are alive at 36 months after orthotopic liver transplantation. One patient, a minor (13 years of age), was transfused per a state court ruling. Erythropoietin increased the production of red blood cells as shown by a mean increase in hematocrit levels of 0.08. Plateletpheresis allowed autologous, platelet-rich plasma to be available for use after allograft reperfusion. Three major complications were resolved or corrected without sequelae. Only one patient developed postoperative hemorrhage, which was corrected surgically. The mean charge for bloodless surgery was $174 000 for the three patients with United Network for Organ Sharing (UNOS) status 3 priority for transplantation. This result was statistically significant when these patients were compared with all the patients with UNOS status 3 priority

    Liver transplantation is an effective treatment for patients with end-stage liver disease. Accurate imaging evaluation of the transplanted patient is critical for ensuring that the limited donor liver is functioning appropriately. Ultrasound contrast agents (UCAs), in combination with contrast-specific imaging techniques, are increasingly accepted in clinical use for the assessment of the hepatic vasculature, bile ducts and liver parenchyma in pre-, intra- and post-transplant patients. We describe UCAs, their technical requirements, the recommended clinical indications, image interpretation and the limitations for contrast-enhanced ultrasound applications in liver transplantation.

    Chronic hepatitis C virus (HCV) infection is the leading cause of death from liver disease and the leading indication for liver transplantation (LT) in the United States and Western Europe. LT represents the best therapeutic alternative for patients with advanced chronic liver disease caused by HCV or those who develop hepatocarcinoma. Reinfection by HCV of the graft is universal and occurs in 95% of transplant patients. This reinfection can compromise graft function and patient survival. In a few cases, the histological recurrence is minimal and non-progressive; however, in most patients it follows a more rapid course than in immunocompetent persons, and frequently evolves into cirrhosis with graft loss. In fact, the five-year and ten-year survival of patients transplanted because of HCV are 75% and 68%, respectively, compared with 85% and 78% in patients transplanted for other reasons. There is also a pattern of recurrence that is very severe, but rare (< 10%), called fibrosing cholestatic hepatitis, which often involves rapid graft loss. Patients who present a negative HCV viremia after antiviral treatment have better survival. Many studies published over recent years have shown that antiviral treatment of post-transplant HCV hepatitis carried out during the late phase is the best option for improving the prognosis of these patients. Until 2011, PEGylated interferon plus ribavirin was the standard of care, resulting in a sustained virological response in around 30% of recipients. The addition of protease inhibitors, such as boceprevir or telaprevir, to the standard of care, or the use of other direct-acting antiviral drugs may involve therapeutic changes in the context of HCV recurrence. This may result a better prognosis for these patients, particularly those with severe recurrence or factors predicting rapid progression of fibrosis. However, the use of these agents in LT still requires clarification in terms of safety and efficacy. PMID:25469009

    We aimed to determine the rate of hepatitis E virus (HEV) infection, a recently increasingly recognized disease in the Western world, in liver transplant patients by direct molecular testing of liver tissue. A RT-PCR assay was designed for detecting the HEV open reading frame (ORF) 2/3 gene region in formalin-fixed, paraffin-embedded tissues, and applied to all liver biopsies (n=683) taken 4 weeks or later from all patients (n=282) after liver transplantation of two large academic centers. HEV-RNA was detected in ten biopsies from four different patients (rate: 1%). Histology in early HEV infection was variable including cases with only few hepatocellular apoptoses, no or only minute inflammation. Hepatitis lasted for at least 6 months in 3/4 patients. Serologic testing for HEV-RNA in a subcohort (159 patients) was positive in five patients (rate: 3%), resulting in an overall HEV detection rate of 3% (8/282). In case both liver tissue and sera of a patient were available from the same time period, all cases tested positive in one material were also tested positive in the other material, respectively. All patients had de novo autochthonous infection with HEV genotype 3. Our data confirm that HEV infection is a relevant cause of liver injury after liver transplantation. Molecular testing for HEV in routinely processed transplant liver biopsies is powerful for evaluating patients with elevated transaminases of unknown origin. Histology of HEV infection under immunosuppression in the early phase is distinct from HEV infection in immunocompetent individuals. PMID:25412844

    Background De novo malignancies occur after liver transplantation because of immunosuppression and improved long-term survival. But the spectrums and associated risk factors remain unclear. Aims To describe the overall pattern of de novo cancers in liver transplant recipients. Methods Data from Scientific Registry of Transplant Recipients from October 1987 to December 2009 were analyzed. The spectrum of de novo cancer was analyzed and logistic-regression was used to identify predictors of do novo malignancies. Results Among 89,036 liver transplant recipients, 6,834 recipients developed 9,717 post-transplant malignancies. We focused on non-skin malignancies. A total of 3,845 recipients suffered from 4,854 de novo non-skin malignancies, including 1,098 de novo hematological malignancies, 38 donor-related cases, and 3,718 de novo solid-organ malignancies. Liver transplant recipients had more than 11 times elevated cancer risk compared with the general population. The long-term overall survival was better for recipients without de novo cancer. Multivariate analysis indicated that HCV, alcoholic liver disease, autoimmune liver disease, nonalcoholic steatohepatitis, re-transplantation, combined transplantation, hepatocellular carcinoma, immunosuppression regime of cellcept, cyclosporine, sirolimus, steroids and tacrolimus were independent predictors for the development of solid malignancies after liver transplantation. Conclusions De novo cancer risk was elevated in liver transplant recipients. Multiple factors including age, gender, underlying liver disease and immunosuppression were associated with the development of de novo cancer. This is useful in guiding recipient selection as well as post-transplant surveillance and prevention. PMID:27171501

    Diagnosis of leishmaniasis in immunosuppressed patients may be a serious challenge for physicians because of the major clinical and laboratory differences with immunocompetent patients. In immunosuppressed patients, the disease is characterized usually by disseminated visceral involvement, atypical cutaneous lesions and persistent negativity of diagnostic tests. Here, we report an eight-yr-old liver transplant recipient with concomitant cutaneous and visceral leishmaniasis in whom the cutaneous lesion led to the diagnosis of systemic involvement.

    The mammalian target of rapamycin (mTOR) inhibitor everolimus is approved for rejection prophylaxis after liver transplantation. The current article pools the experience of French liver transplant surgeons and physicians in use of everolimus and, particularly, practical guidance on dosing, appropriate concomitant immunosuppression and management of adverse events. In terms of indication, introduction of everolimus from week 4 after liver transplantation, with or without concomitant calcineurin inhibitor (CNI) therapy, offers a significant renal benefit without loss of immunosuppressive efficacy. De novo treatment with everolimus, either selectively or systematically, may play a role in the prevention and treatment of recurrence of hepatocellular cancer and de novo malignancies. For maintenance patients, the most frequent indications for introducing everolimus are in response to renal dysfunction, recurrent hepatocellular cancer, diabetes, hypertension, or neurotoxicity, or as a preventative approach to avoid malignancies. Of these, the strongest evidence exists for a renoprotective effect. However, the low rate of acute rejection following switch of maintenance patients from CNI-based to everolimus-based therapy means that this can be considered even where robust data are not yet available. Most adverse events associated with mTOR inhibitors can usually be managed successfully, often with concentration-controlled dose reductions. Dosing algorithms are provided, with suggestions for target ranges in specific settings, and treatment strategies for the most common side effects are proposed. Although further research is required, everolimus has become an established part of the immunosuppressive arsenal for liver transplant recipients over the last decade. Sharing experience from units which have embraced its use may help other centers develop their own protocols. PMID:27083870

    Chronic hepatitis B virus (HBV) infection is responsible for up to 30% of cases of liver cirrhosis and up to 53% of cases of hepatocellular carcinoma. Liver transplantation (LT) is the best therapeutic option for patients with end-stage liver failure caused by HBV. The success of transplantation, though, depends on receiving prophylactic treatment against post-transplant viral reactivation. In the absence of prophylaxis, liver transplantation due to chronic hepatitis B (CHB) is associated with high rates of viral recurrence and poor survival. The introduction of treatment with hepatitis B immunoglobulins (HBIG) during the 1990s and later the incorporation of oral antiviral drugs have improved the prognosis of these patients. Thus, LT for CHB is now a universally accepted option, with an estimated 5 years survival of around 85% vs the 45% survival seen prior to the introduction of HBIG. The combination of lamivudine plus HBIG has for many years been the most widely used prophylactic regimen. However, with the appearance of new more potent oral antiviral agents associated with less resistance (e.g., entecavir and tenofovir) for the treatment of CHB, new prophylactic strategies are being designed, either in combination with HBIG or alone as a monotherapy. These advances have allowed for more personalized prophylaxis based on the individual risk profile of a given patient. In addition, the small pool of donors has required the use of anti-HBc-positive donors (with the resulting possibility of transmitting HBV from these organs), which has been made possible by suitable prophylactic regimens.

    The renewed interest in donation after cardio-circulatory death (DCD) started in the 1990s following the limited success of the transplant community to expand the donation after brain-death (DBD) organ supply and following the request of potential DCD families. Since then, DCD organ procurement and transplantation activities have rapidly expanded, particularly for non-vital organs, like kidneys. In liver transplantation (LT), DCD donors are a valuable organ source that helps to decrease the mortality rate on the waiting lists and to increase the availability of organs for transplantation despite a higher risk of early graft dysfunction, more frequent vascular and ischemia-type biliary lesions, higher rates of re-listing and re-transplantation and lower graft survival, which are obviously due to the inevitable warm ischemia occurring during the declaration of death and organ retrieval process. Experimental strategies intervening in both donors and recipients at different phases of the transplantation process have focused on the attenuation of ischemia-reperfusion injury and already gained encouraging results, and some of them have found their way from pre-clinical success into clinical reality. The future of DCD-LT is promising. Concerted efforts should concentrate on the identification of suitable donors (probably Maastricht category III DCD donors), better donor and recipient matching (high risk donors to low risk recipients), use of advanced organ preservation techniques (oxygenated hypothermic machine perfusion, normothermic machine perfusion, venous systemic oxygen persufflation), and pharmacological modulation (probably a multi-factorial biologic modulation strategy) so that DCD liver allografts could be safely utilized and attain equivalent results as DBD-LT.

    Liver steatosis is a prevalent process that is induced due to alcoholic or non-alcoholic intake. During the course of these diseases, the generation of reactive oxygen species, followed by molecular damage to lipids, protein and DMA occurs generating organ cell death. Transplantation is the last-resort treatment for the end stage of both acute and chronic hepatic diseases, but its success depends on ability to control ischemia-reperfusion injury, preservation fluids used, and graft quality. Melatonin is a powerful endogenous antioxidant produced by the pineal gland and a variety of other because of its efficacy in organs; melatonin has been investigated to improve the outcome of organ transplantation by reducing ischemia-reperfusion injury and due to its synergic effect with organ preservation fluids. Moreover, this indolamine also prevent liver steatosis. That is important because this disease may evolve leading to an organ transplantation. This review summarizes the observations related to melatonin beneficial actions in organ transplantation and ischemic-reperfusion models. PMID:27022943

    Anesthesia for liver transplantation (ALT) requires extensive preparation and rapid recognition of changing clinical conditions. Owing to the proliferation of transplant centers, greater number of anesthesia providers need training in specific skills required to treat these patients. These cases are no longer limited to few transplant centers; therefore, reduction of cases in individual centers has created a need for simulation training to prepare and supplement clinical experience. We have developed an ALT simulation course for senior anesthesia residents which combines didactic sessions with live-patient-based and mannequin-based simulation. Outcomes have been measured using pre- and post-simulation course quizzes as well as a survey given at the end of the month-long ALT rotation. Twenty-four senior anesthesiology residents (n = 24) have completed the ALT simulation course. Residents had an average score of 75% ± 10% on the pre-simulation quiz, which increased to 92% ± 6.5% on the post-simulation quiz (p < 0.001). Furthermore, survey scores indicated that residents noted that the course provided an improvement in their preparedness, confidence, anticipation, and understanding of the importance of communication skills in the care of this patient population. The ALT simulation course provided a standardized in-depth exposure to clinical issues involved in the perioperative care of liver transplant patients. PMID:22211653

    Cytomegalovirus (CMV) remains a major cause of problems following solid organ transplantation, accounting for a significant increase in morbidity and affiliated costs. Infection with CMV following orthotopic liver transplantation (OLT) is commonly seen as a result of marked cell-mediated immunosuppression and is an independent risk factor for opportunistic and fungal infections. The role of CMV infection in acute cellular or chronic rejection remains unclear. Recent advances in diagnostic modalities, particularly the use of the antigenemia assay and the polymerase chain reaction, have provided ways to quantitate viral load during infection or disease, as well as providing a useful marker of response to therapy. Ganciclovir remains the best antiviral agent for the treatment of CMV disease, but the use of combination therapy with other antivirals or CMV immunoglobulin may improve outcome for patients with severe disease. The ideal prophylactic therapy for patients undergoing OLT remains to be identified, as tested regimens have shown variable efficacy when analyzed with regard to defined risk groups. The use of risk group-specific prophylaxis may prove to be most successful, however, in terms of efficacy and cost savings. Future advances in basic CMV virology and transplant immunology will be essential in defining rational approaches to control and prevention of CMV infection and disease following liver transplantation.

    Tc-NGA is a hepatocyte receptor-specific imaging agent whose uptake by the liver has been shown to be dependent upon blood flow and receptor concentration. The combination of anatomic and physiologic information obtained with Tc-NGA may provide a new tool for studying hepatic function in liver transplant recipients. To evaluate the potential role of Tc-NGA in liver transplant recipients, studies were performed in four groups of pigs: controls (n=18); common bile duct (CBD) ligation (n=8); orthotopic liver transplant (n=9); and acute hepatic artery ligation (n=1). Serial studies performed in two animals with CBD ligation demonstrated normal imaging anatomy with minor changes in the hepatic time-activity curves when compared to control studies. Studies in liver-transplanted animals showed significant changes in the hepatic time-activity curves during acute rejection and in preservation-related ischemic injury. Tc-NGA also demonstrated focal areas of hepatic infarction in a hepatic allograft within 24 hours of transplantation. The hepatic artery ligation study showed massive changes in the hepatic time-activity curve within two hours after ligation, with a diffuse decrease in hepatic activity. These results indicate that: (1) extrahepatic biliary tract obstruction causes only minor changes in Tc-NGA uptake; (2) Tc-NGA uptake by the liver is very sensitive to acute hepatic ischemia; (3) Tc-NGA may indicate the presence of preservation damage in the early postoperative period; and (4) Tc-NGA hepatic time-activity curves demonstrate significant changes during acute rejection.

    We report a case of transient symptomatic transferred IgE-mediated peanut allergy after elective blood-group compatible liver transplantation. We show that the allergy was transient and therefore passive, authorizing further uneventful peanut consumption. Skin tests with commercial peanut extract and native peanut were performed in the recipient. Circulating specific IgE against peanut and recombinant peanut allergens (rArah1, rArah2, rArah3) was measured in stored serum samples collected from the recipient between 6 months before and 8 months after liver transplantation. Specific IgE levels in the donor were measured at the time of multiorgan donation. In the recipient, diagnosis of IgE-mediated peanut anaphylaxis was based on the clinical history and detection of specific IgE against peanut and recombinant major peanut allergens (rArah1, rArah2 and rArah3). Skin tests were negative and specific IgE undetectable 6 months after the clinical reaction. Oral peanut challenge was negative excluding persistent peanut allergy. This case confirms that IgE-mediated peanut allergy can be transferred by liver transplantation and shows that it may be transient and therefore passively acquired. PMID:21668638

    End stage liver disease (ESLD) is associated with many specific derangements in cardiovascular physiology, which influence perioperative outcomes and may profoundly influence diagnostic and management strategies in the preoperative period. This review focuses on evidence-based diagnosis and management of coronary, hemodynamic and pulmonary vascular disease in this population with an emphasis on specific strategies that may provide a bridge to transplantation. Specifically, we address the underlying prevalence of cardiovascular disease states in the ESLD population, and relevant diagnostic criteria thereof. We highlight traditional and non-traditional predictors of cardiovascular outcomes following liver transplant, as well as data to guide risk-factor based diagnostic strategies. We go on to discuss the alterations in cardiovascular physiology which influence positive- and negative-predictive values of standard noninvasive testing modalities in the ESLD population, and review the data regarding the safety and efficacy of invasive testing in the face of ESLD and its co-morbidities. Finally, based upon the totality of available data, we outline an evidence-based approach for the management of ischemia, heart failure and pulmonary vascular disease in this population. It is our hope that such evidence-driven strategies can be employed to more safely bridge appropriate candidates to liver transplant, and to improve their cardiovascular health and outcomes in the peri-operative period.

    Introduction. The venovenous/portal venous (VVP) bypass technique has generally become obsolete in liver transplantation (LT) today. We evaluated our experience with 163 consecutive LTs that used a VVP bypass. Patients and Methods. The liver transplant program was started in our center in 2010. LTs were performed using an extracorporal bypass device. Results. Mean operative time was 269 minutes and warm ischemic time 43 minutes. The median number of transfusion of packed cells and plasma was 7 and 14. There was no intraoperative death, and the 30-day mortality was 3%. Severe bypass-induced complications did not occur. Discussion. The introduction of a new LT program requires maximum safety measures for all of the parties involved. Both surgical and anaesthesiological management (reperfusion) can be controlled very reliably using a VVP bypass device. Particularly when using marginal grafts, this approach helps to minimise both surgical and anaesthesiological complications in terms of less volume overload, less use of vasopressive drugs, less myocardial injury, and better peripheral blood circulation. Conclusion. Based on our experiences while establishing a new liver transplantation program, we advocate the reappraisal of the extracorporeal VVP bypass. PMID:25821462

    Liver transplantation (LT) is an established approach to treatment of end-stage liver diseases, metabolic diseases and early hepatocellular carcinoma, and the results of this procedure have improved considerably. MELD allocation and the great number of transplant centers had a negative influence on outcome in Germany. Typical surgical issues following transplantation are vascular thrombosis and the development of biliary lesions. Nonanastomotic strictures impact graft survival and cause considerable posttransplant morbidity. Nonsurgical issues in LT are hepatitis C reinfection, selection of appropriate patients with hepatocellular carcinoma and individualized immunosuppression. In hepatitis C the new antiviral drugs (protease and polymerase inhibitors) are promising tools to prevent reinfection. Nephrotoxicity caused by calcineurin inhibitors - which remain the mainstay of immunosuppression - can only partially be avoided. So far, alternative forms of treatment using mycophenolic acid and mTOR inhibitors cannot totally replace calcineurin inhibitors. In view of graft scarcity, we need to think about a benefit-based model of liver allocation which focuses on the optimal use of this resource. Deciding on this form of organ allocation requires an ethical consensus: not the most urgent patient is the first candidate to receive a graft, but rather the patient who is supposed to have the greatest benefit.

    It is now accepted that patients with a liver transplantation regain the ability to lead a normal life within months of surgery, but at the price of lifetime immunosuppressive treatment and specific regular surveillance. A balanced and diversified diet, together with regular physical activity is necessary to prevent, limit, or delay the development of the cardiovascular complications that determine the prognosis for long-term survival. Attenuated live vaccines are contraindicated in patients treated with immunosuppressants to avoid the risk of reversion of the attenuation of the virus or bacteria. Travel abroad is possible to places with good sanitary conditions, if the patient increases his or her vigilance for any contagious infection. The global incidence of cancer is higher than in the general population, justifying specific and regular testing and clinical monitoring. A planned pregnancy is possible in patients stabilized after liver transplantation, and prognosis is most often good for mother and child. Early multidisciplinary management is essential because of the elevated risks of fetal growth restriction and preterm delivery. The global perception of quality of life increases after liver transplantation, but remains lower than in healthy subjects. PMID:19586750

    Background Despite of recent development of imaging modalities, congenital intrahepatic portosystemic shunt (IPSS) is rarely diagnosed. Therefore, living donor liver transplantation using a liver graft with IPSS has not been previously published. Materials and Methods We report a 28-year-old male patient with end-stage liver disease secondary to Wilson disease. His 26-year-old brother was a potential living donor, who had an IPSS of 25 mm in diameter at segment 6 as shown by computed tomography. Liver function tests were normal, and blood ammonia concentration was in the upper limit of normal. Results Living donor liver transplantation was uneventfully performed. After surgery, a recipient liver function tests showed a quick recovery, and serum ammonia levels were consistently normal. Although thrombosis inside the IPSS was confirmed by computed tomography on postoperative day 21, this thrombosis disappeared at 3 months posttransplant with anticoagulants. Currently (12 months posttransplant), the patient has fully recovered, and the IPSS is still the same size. Conclusions Based on our experience, liver allografts with IPSS can be accepted as potential liver allografts.

    Purpose: To establish an animal model of improved donor liver position selection and revascularization for heterotopic auxiliary liver transplantation with portal vein arterialization (HALT-PVA). Methods: Sprague-Dawley rats were utilized to establish models. Improved HALT-PVA was conducted for the experimental rat: hepatic common artery of donor liver was end-to-side anastomosed to portal vein which was end-to-side anastomosed to the left common iliac artery of host rat, while the segments of inferior vena cava superior and inferior to the donor liver were end-to-side anastomosed to the inferior vena cava of host rat, respectively. For the control rats, liver transplantations were conducted through end-to-end anastomosis between portal vein of donor liver and stand tube placed in right renal artery of host rat, and end-to-side anastomosis between the inferior vena cava inferior to the donor liver with the inferior vena cava of host rat, while the inferior vena cava superior to the donor liver was stitched up. Besides, hepaticoenterostomy were performed to all rats and survival status were monitored. ALT, AST, TBil and CHE were tested continuously after operation, and pathological examination of liver tissues were performed. Results: The survival rate was 93.3% (14/15). ALT, AST, TBil and CHE for experimental group showed a rapider recovery of liver functions than controls. Pathological examinations of liver tissues from the experimental-group rats showed better presentation than the control-group rats. Conclusions: The improved HALT-PVA better accords with the normal anatomy, with little detriment to implanted liver, and therefore is a good model for HALT-PVA related research. PMID:26770477

    Liver stiffness measurement (LSM) is a useful method to estimate liver fibrosis and portal hypertension. The inflammatory process that takes place in post-liver transplant acute cellular rejection (ACR) may also increase liver stiffness. We aimed to explore the association between liver stiffness and the severity of ACR, as well as to assess the relationship between liver stiffness and response to rejection treatment in a prospective study that included 27 liver recipients with biopsy-proven ACR, 30 stable recipients with normal liver tests, and 30 hepatitis C virus (HCV)-infected LT recipients with histologically diagnosed HCV recurrence. Patients with rejection were stratified into 2 groups (mild and moderate/severe) according to the severity of rejection evaluated with the Banff score. Routine biomarkers and LSM with FibroScan were performed at the time of liver biopsy (baseline) and at 7, 30, and 90 days in patients with rejection and at baseline in control patients. Median baseline liver stiffness was 5.9 kPa in the mild rejection group, 11 kPa in the moderate/severe group (P = 0.001), 4.2 kPa in stable recipients (P = 0.02 versus mild rejection), and 13.6 kPa in patients with recurrent HCV (P = 0.17 versus moderate/severe rejection). The area under the receiver operator characteristic curve of LSM to discriminate mild versus moderate/severe ACR was 0.924, and a LSM value of 8.5 kPa yielded a positive predictive value of 100% to diagnose moderate/severe rejection. Liver stiffness improved in 7%, 21%, and 64% of patients with moderate/severe rejection at 7, 30, and 90 days. In conclusion, according to the results of this exploratory study, LSM is associated with the severity of ACR in liver transplantation and thus may be of help in its assessment. PMID:26609794

    The large MRC/ECOG Adult Acute Lymphoblastic Leukemia Study establishes the value of sibling donor allogeneic transplantation in patients with standard risk, demonstrating superior outcome to conventional chemotherapy. The small but significant number of patients having matched unrelated donor transplantations on this study protocol appear to do well and might establish the value of such an approach for those without a sibling. Reduced-intensity conditioning might begin to address the transplantation-related mortality problems of the older patients. The youngest adults might not need to undergo transplantation at all. If they are now treated on pediatric chemotherapy protocols, their outcome appears to improve significantly. PMID:19778843

    Combined lung-liver transplantation is a logistically challenging procedure hampered by shortage of organ donors. We describe the case of a young patient with end-stage lung disease due to of cystic fibrosis and liver cirrhosis who needed combined lung-liver transplantation. The long waiting for this caused an interesting clinical dilemma. We decided to change our policy in this situation by listing him only for the lung transplantation and to apply for a high urgent liver transplantation if the liver failed after the lung transplantation. This strategy enabled us to use lungs treated with ex vivo lung perfusion (EVLP) from an unsuitable donor after circulatory death. After conditioning for 4 h via EVLP, the pO2 was 59.7 kPa. The lungs were transplanted successfully. He developed an acute-on-chronic liver failure for which he received a successful liver transplantation 19 days after the lung transplantation.

    The use of large databases has provided advancements in the understanding of racial, ethnic, and socioeconomic disparities in the field of adult hematopoietic cell transplants (HCT). Disparities exist on individual, institutional, and systemic levels for both allogeneic and autologous HCT. We reviewed the most recent publications that utilized large databases to elucidate disparities in HCT and placed them into historical context of the other major studies in the field. Two emerging themes were identified. These themes are persistent inequalities in both allogeneic HCT and autologous HCT for myeloma and the importance of improving homogeneity of care in HCT. Minimization of inequalities can be achieved only with an understanding of the persistent barriers that exist in the field. PMID:26104908

    Biliary atresia (BA), a chronic progressive cholestatic disease of infants, is the leading cause for liver transplant in children, especially in patients under two years of age. BA can be successfully treated with the Kasai portoenterostomy; however most patients still require a liver transplant, with up to one half of BA children needing a transplant by age two. In the current pediatric end-stage liver disease system, children with BA face the risk of not receiving a liver in a safe and timely manner. In this review, we discuss a number of possible solutions to help these children. We focus on two general approaches: (1) preventing/delaying need for transplantation, by optimizing the success of the Kasai operation; and (2) expediting transplantation when needed, by performing techniques other than the standard deceased-donor, whole, ABO-matched organ transplant.

    Hepatocyte transplantation has excited much interest in lending temporary metabolic support to a failing liver following acute liver injury. The exact site from which they act and the clinical, biochemical, and histological changes in the recipient body following hepatocyte transplantation is yet to be worked out. The present study is an attempt to delineate location and function of transplanted hepatocytes and also the overall survival of these cells with a fluorescent in situ hybridization (FISH) technique using a Y-chromosome-specific probe in a carbon tetrachloride (CCl4)-induced mice model of fulminant hepatic failure. Fifty-five syngenic adult Swiss female mice of approximately the same age and body weight were divided into three groups. Group-1 (n = 15), which received mineral oil, served as a negative control. Group-II (n = 15) received CCl4 (3 mL/kg) 40% vol/vol in mineral oil, by gavage served as positive control for hepatic failure. Group-III (n = 25) received intrasplenic transplantation of syngenic single cell suspension of hepatocytes in Hanks medium, after 30 h of CCl4 administration. Male Swiss adult mice (n = 15) served as donors of hepatocytes. The overall survival of animals in groups I to III was 100, 0, and 70%, respectively, by 2 wk of the study period. Transplanted hepatocytes were identified by Periodic Acid Schiff (PAS) staining and confirmed with a FISH technique using the Y-chromosome probe. The majority of exogenously transplanted hepatocytes were found in the liver and spleen sections even after 1 wk of hepatocyte transplantation. Transplanted cells were mostly found to be translocated into the sinusoids of the liver. Transplanted hepatocytes were found to be beneficial as a temporary liver support in a failing liver, significantly improving the survival of the animals. In the present study, the FISH technique was used to unequivocally distinguish the transplanted cells from the host, and thus describes a model for studying the

    During the last couple of decades, with standardization and progress in surgical techniques, immunosuppression and post liver transplantation patient care, the outcome of liver transplantation has been optimized. However, the principal limitation of transplantation remains access to an allograft. The number of patients who could derive benefit from liver transplantation markedly exceeds the number of available deceased donors. The large gap between the growing list of patients waiting for liver transplantation and the scarcity of donor organs has fueled efforts to maximize existing donor pool and identify new avenues. This article reviews the changing pattern of donor for liver transplantation using grafts from extended criteria donors (elderly donors, steatotic donors, donors with malignancies, donors with viral hepatitis), donation after cardiac death, use of partial grafts (split liver grafts) and other suboptimal donors (hypernatremia, infections, hypotension and inotropic support).

    This study was a retrospective analysis of the European Liver Transplant Registry (ELTR) performed to compare long-term outcomes with prolonged-release tacrolimus versus tacrolimus BD in liver transplantation (January 2008-December 2012). Clinical efficacy measures included univariate and multivariate analyses of risk factors influencing graft and patient survival at 3 years posttransplant. Efficacy measures were repeated using propensity score-matching for baseline demographics. Patients with <1 month of follow-up were excluded from the analyses. In total, 4367 patients (prolonged-release tacrolimus: n = 528; BD: n = 3839) from 21 European centers were included. Tacrolimus BD treatment was significantly associated with inferior graft (risk ratio: 1.81; p = 0.001) and patient survival (risk ratio: 1.72; p = 0.004) in multivariate analyses. Similar analyses performed on the propensity score-matched patients confirmed the significant survival advantages observed in the prolonged-release tacrolimus- versus tacrolimus BD-treated group. This large retrospective analysis from the ELTR identified significant improvements in long-term graft and patient survival in patients treated with prolonged-release tacrolimus versus tacrolimus BD in primary liver transplant recipients over 3 years of treatment. However, as with any retrospective registry evaluation, there are a number of limitations that should be considered when interpreting these data. PMID:25703527

    Living related liver transplantation (LRLT) is a valuable transplant option for children with end-stage liver disease who face long waiting times on regular waiting lists. The subjection of a healthy adult to a potentially life-threatening operation can raise issues of freedom of choice, fear, and family conflict for the potential donors. We examined attitudes, fears, and influencing factors in the decision-making process for living liver donation for children in order to identify factors to improve support for living liver donors in the future. In a retrospective, questionnaire-based survey of 93 adults evaluated for living liver donation between 1997 and 2010, 47 of whom actually proceeded to donation, we asked about attitudes, motivation, fears, influencing factors, and well-being during the LRLT evaluation process and during the donation period. Answers were recorded on Likert scales and compared with Pearson's rho correlation and the Mann-Whitney U test as appropriate. Although there was a strong sense of a lack of alternatives among the donors, the majority of the donors felt free in their decision to donate. Donors who were asked to donate for a relative who was not their own child appeared at higher risk of lacking support and of feeling coerced. Family and social support and good and empathic information about the donation process were identified as key factors for donor well-being. In conclusion, potential living liver donors need to have adequate, sufficient, and empathic information, and they need to be provided a supportive framework, including family support, in order to promote their well-being. Care needs to be taken in identifying and counseling potential donors at risk of feeling coerced into donation. PMID:25504770

    The authors successfully performed a series of 33 living related liver transplantations (LRLT) on children (15 males and 18 females, ranging from 7 months to 15 years of age) from June 1990 to May 1992, with the informed consent of their parents and the approval of the Ethics Committee of Kyoto University. Before operation, six of the children required intensive care, another 14 were hospitalized, and 13 were homebound. Donors (12 paternal and 21 maternal) were selected solely from the parents of the recipients on the basis of ABO blood group and graft/recipient size matching determined by computed tomography scanning. Procurement of graft was performed using ultrasonic aspirator and bipolar electrocautery without blood vessel clamping and without graft manipulation. All donors subsequently had normal liver function and returned to normal life. The left lateral segment (16 cases), left lobe (16 cases), or right lobe (one case) were used as grafts. The partial liver graft was transplanted into the recipient who underwent total hepatectomy with preservation of the inferior vena cava using a vascular side clamp. Twenty-seven of 33 recipients are alive and well with the original graft and have normal liver function. The patient survival rate was 89% (24/27) in elective cases and 50% (3/6) in emergent cases. The other six recipients had functioning grafts but died of extrahepatic complications. Complications of the graft were minimal in all cases. Hepatic vein stenosis, which occurred three times in two cases, was successfully treated by balloon dilatation. In cases with sclerotic portal vein, the authors anastomosed the portal vein of the graft to the confluence of the splenic vein and the superior mesenteric vein without a vascular graft, after experiencing a case of vascular graft thrombosis. After hepatic artery thrombosis occurred in one of the initial seven recipients whose arterial anastomosis was done with surgical loupe, microsurgery was introduced for hepatic

    Introduction Incidence of Clostridium difficile infection (CDI) is increasing among hospitalized patients. Liver transplant patients are at higher risk for acquiring CDI. Small, single-center studies, but no nation-wide analyses, have assessed this association. Methods We used the Healthcare Cost and Utilization Project- Nationwide Inpatient Sample (HCUP-NIS) from years 2004–2008 for this retrospective cross sectional study. Patients with any discharge diagnosis of liver transplant comprised the study population and were identified using ICD-9-CM codes. Those with a discharge diagnosis of CDI were considered cases. Our primary outcomes were prevalence of CDI and effect of CDI on inpatient mortality. Our secondary outcomes included length of stay and hospitalization charges. Regression analysis was used to derive odds ratios adjusted for potential confounders. Results There were 193,714 discharges with a diagnosis of liver transplant from 2004–2008. Prevalence of CDI was 2.7% in liver transplant population compared to 0.9% in non liver transplant population (p <0.001). Most of the liver transplant patients were in the 50–64 age group. Liver transplant patients were at higher odds of developing CDI (OR 2.88, 95% CI 2.68–3.10). Increasing age, increasing comorbidity, IBD and NG tube placement were also independent risk factors for CDI. CDI in liver transplant was associated with a higher mortality, 5.5% as compared to 2.3% in liver transplant only population (adjusted OR 1.7, 95% CI 1.3–2.2). Conclusions Liver transplant patients have a higher prevalence of CDI as compared to non liver transplant patients (2.7% vs. 0.9%).CDI was an independent risk factor for mortality in liver transplant population.

    Progressive liver allograft fibrosis (LAF) is well known to occur long term, as shown by its high prevalence in late posttransplant liver biopsies (LBs). To evaluate the influence of clinical variables and immunosuppression on LAF progression, LAF dynamic was assessed in 54 pediatric liver transplantation (LT) recipients at 6 months, 3 and 7 years post-LT, reviewing clinical, biochemical data and protocol LBs using METAVIR and the liver allograft fibrosis score, previously designed and validated specifically for LAF assessment. Scoring evaluations were correlated with fibrosis quantification by morphometric analysis. Progressive LAF was found in 74% of long-term patients, 70% of whom had unaltered liver enzymes. Deceased grafts showed more fibrosis than living-related grafts (p = 0.0001). Portal fibrosis was observed in correlation with prolonged ischemia time, deceased grafts and lymphoproliferative disease (p = 0.001, 0.006 and 0.012, respectively). Sinusoidal fibrosis was correlated with biliary complications (p = 0.01). Centrilobular fibrosis was associated with vascular complications (p = 0.044), positive autoantibodies (p = 0.017) and high gamma-globulins levels (p = 0.028). Steroid therapy was not associated with reduced fibrosis (p = 0.83). LAF could be viewed as a dynamic process with mostly progression along the time. Peri- and post-LT-associated factors may condition fibrosis development in a specific area of the liver parenchyma. PMID:24934832

    The aim of this review is to enlighten the critical roles that the liver plays in cholesterol metabolism. Liver transplantation can serve as gene therapy or a source of gene transmission in certain conditions that affect cholesterol metabolism, such as low-density-lipoprotein (LDL) receptor gene mutations that are associated with familial hypercholesterolemia. On the other hand, cholestatic liver disease often alters cholesterol metabolism. Cholestasis can lead to formation of lipoprotein X (Lp-X), which is frequently mistaken for LDL on routine clinical tests. In contrast to LDL, Lp-X is non-atherogenic, and failure to differentiate between the two can interfere with cardiovascular risk assessment, potentially leading to prescription of futile lipid-lowering therapy. Statins do not effectively lower Lp-X levels, and cholestasis may lead to accumulation of toxic levels of statins. Moreover, severe cholestasis results in poor micellar formation, which reduces cholesterol absorption, potentially impairing the cholesterol-lowering effect of ezetimibe. Apolipoprotein B-100 measurement can help distinguish between atherogenic and non-atherogenic hypercholesterolemia. Furthermore, routine serum cholesterol measurements alone cannot reflect cholesterol absorption and synthesis. Measurements of serum non-cholesterol sterol biomarkers - such as cholesterol precursor sterols, plant sterols, and cholestanol - may help with the comprehensive assessment of cholesterol metabolism. An adequate cholesterol supply is essential for liver-regenerative capacity. Low preoperative and perioperative serum cholesterol levels seem to predict mortality in liver cirrhosis and after liver transplantation. Thus, accurate lipid profile evaluation is highly important in liver disease and after liver transplantation. PMID:27574546

    Hepatocellular carcinoma (HCC) is an aggressive tumor that often occurs in chronic liver disease and cirrhosis. The incidence of HCC is growing worldwide. With respect to any other available treatment for liver cancer, liver transplantation (LT) has the highest potential to cure. LT allows for removal at once of both the tumor ("seed") and the damaged-hepatic tissue ("soil") where cancerogenesis and chronic liver disorders have progressed together. The Milan criteria (MC) have been applied worldwide to select patients with HCC for LT, yielding a 4-year survival rate of 75%. These criteria represent the benchmark for patient selection and are the basis for comparison with any other suggested criteria. However, MC are often considered to be too restrictive, and recent data show that between 25% and 50% of patients with HCC are currently transplanted beyond conventional indications. Consequently, any unrestricted expansion of selection criteria will increase the need for donor organs, lengthen waiting periods, increase drop-out rates, and impair outcomes on intention-to-treat analysis. Management of HCC recurrence after LT is challenging. There are a few reports available regarding the safety and efficacy of sorafenib for HCC recurrence after LT, but the data are heterogeneous. A multi-center prospective randomized controlled trial comparing placebo with sorafenib is advised. Alternatively, a meta-analysis of patient survival with sorafenib for HCC recurrence after LT could be helpful to characterize the therapeutic benefit and safety of sorafenib. Here, we review the use of LT for HCC, with particular emphasis on the selection criteria for transplantation in patients with HCC and management of HCC recurrence after LT. PMID:26357625

    Biliary complications are common after living donor liver transplant (LDLT) although with advancements in surgical understanding and techniques, the incidence is decreasing. Biliary strictures are more common than leaks. Endoscopic retrograde cholangiopancreatography (ERCP) is the first line modality of treatment of post LDLT biliary strictures with a technical success rate of 75%-80%. Most of ERCP failures are successfully treated by percutaneous transhepatic biliary drainage (PTBD) and rendezvous technique. A minority of patients may require surgical correction. ERCP for these strictures is technically more challenging than routine as well post deceased donor strictures. Biliary strictures may increase the morbidity of a liver transplant recipient, but the mortality is similar to those with or without strictures. Post transplant strictures are short segment and soft, requiring only a few session of ERCP before complete dilatation. Long-term outcome of patients with biliary stricture is similar to those without stricture. With the introduction of new generation cholangioscopes, ERCP success rate may increase, obviating the need for PTBD and surgery in these patients. PMID:27057304

    Ultrasound guided fine needle aspiration cytology (FNAC) and core needle biopsy (CNB) are effective methods for the diagnosis of focal hepatic lesions. In case of neoplastic lesions, however, this may be followed by the seeding of malignant cells along the needle tract. We report a case of subcutaneous needle tract seeding of hepatocellular carcinoma (HCC) 25 months after liver transplantation. A 57-year-old man with compensated hepatitis-B-related liver cirrhosis was diagnosed with HCC by CNB, and the lesion was resected. Ten months after the procedure, FNAC of a small hepatic lesion confirmed tumor recurrence. The patient was successfully transplanted and 25 months later, a subcutaneous tumor appeared on the abdominal wall over the previous site of puncture without further dissemination of the disease. Total resection of the lesion confirmed HCC. It remains undetermined whether the seeding appeared after FNAC or CNB. After 18-month follow-up the patient was uneventful. The objectives of this report are to present clinical aspects and outcome of HCC needle tract seeding in a transplanted patient, discussing the problems and pitfalls of diagnostic workup and management of HCC.

    Autoimmune liver diseases (AILD) are rare diseases with a reported prevalence of less than 50 per 100 000 population. As the research landscape and our understanding of AILDs and liver transplantation evolves, there remain areas of unmet needs. One of these areas of unmet needs is prevention of disease recurrence after liver transplantation. Disease recurrence is not an insignificant event because allograft loss with the need for retransplantation can occur. Patients transplanted for AILD are more likely to experience acute rejection compared to those transplanted for non-AILD, and the reason(s) behind this observation is unclear. Tasks for the future include a better understanding of the pathogenesis of AILD, definition of the precise pathogenetic mechanisms of recurrent AILD, and development of strategies that can identify recipients at risk for disease recurrence. Importantly, the role of crosstalk between alloimmune responses and autoimmune responses in AILD is an important area that needs further study.This article reviews the relevant literature of de novo autoimmune hepatitis, recurrent autoimmune hepatitis, recurrent primary sclerosing cholangitis, and recurrent primary biliary cirrhosis in terms of the clinical entity, the scientific advancements, and future scientific goals to enhance our understanding of these diseases.

    National liver transplantation (LT) volume has declined since 2006, in part because of worsening donor organ quality. Trends that degrade organ quality are expected to continue over the next 2 decades. We used the United Network for Organ Sharing (UNOS) database to inform a 20-year discrete event simulation estimating LT volume from 2010 to 2030. Data to inform the model were obtained from deceased organ donors between 2000 and 2009. If donor liver utilization practices remain constant, utilization will fall from 78% to 44% by 2030, resulting in 2230 fewer LTs. If transplant centers increase their risk tolerance for marginal grafts, utilization would decrease to 48%. The institution of "opt-out" organ donation policies to increase the donor pool would still result in 1380 to 1866 fewer transplants. Ex vivo perfusion techniques that increase the use of marginal donor livers may stabilize LT volume. Otherwise, the number of LTs in the United States will decrease substantially over the next 15 years. In conclusion, the transplant community will need to accept inferior grafts and potentially worse posttransplant outcomes and/or develop new strategies for increasing organ donation and utilization in order to maintain the number of LTs at the current level.

    2015-01-01

    Alcoholic liver disease (ALD) is the second most common diagnosis among patients undergoing liver transplantation (LT). The recovery results of patients transplanted for ALD are often at least as good as those of patients transplanted for other diagnoses and better than those suffering from hepatitis C virus, cryptogenic cirrhosis, or hepatocellular carcinoma. In the case of medically non-responding patients with severe acute alcoholic hepatitis or acute-on chronic liver failure, the refusal of LT is often based on the lack of the required alcohol abstinence period of six months. The obligatory abidance of a period of abstinence as a transplant eligibility requirement for medically non-responding patients seems unfair and inhumane, since the majority of these patients will not survive the six-month abstinence period. Data from various studies have challenged the 6-mo rule, while excellent survival results of LT have been observed in selected patients with severe alcoholic hepatitis not responding to medical therapy. Patients with severe advanced ALD should have legal access to LT. The mere lack of pre-LT abstinence should not be an obstacle for being listed. PMID:25892898

    We report our experience with potential donors for living donor liver transplantation (LDLT), which is the first report from an area where there is no legalized deceased donation program. This is a single center retrospective analysis of potential living donors (n = 1004) between May 2004 and December 2012. This report focuses on the analysis of causes, duration, cost, and various implications of donor exclusion (n = 792). Most of the transplant candidates (82.3%) had an experience with more than one excluded donor (median = 3). Some recipients travelled abroad for a deceased donor transplant (n = 12) and some died before finding a suitable donor (n = 14). The evaluation of an excluded donor is a time-consuming process (median = 3 d, range 1 d to 47 d). It is also a costly process with a median cost of approximately 70 USD (range 35 USD to 885 USD). From these results, living donor exclusion has negative implications on the patients and transplant program with ethical dilemmas and an economic impact. Many strategies are adopted by other centers to expand the donor pool; however, they are not all applicable in our locality. We conclude that an active legalized deceased donor transplantation program is necessary to overcome the shortage of available liver grafts in Egypt. PMID:25309092

  16. Predictive roles of intraoperative blood glucose for post-transplant outcomes in liver transplantation.

    Diabetogenic traits in patients undergoing liver transplantation (LT) are exacerbated intraoperatively by exogenous causes, such as surgical stress, steroids, blood transfusions, and catecholamines, which lead to intraoperative hyperglycemia. In contrast to the strict glucose control performed in the intensive care unit, no systematic protocol has been developed for glucose management during LT. Intraoperative blood glucose concentrations typically exceed 200 mg/dL in LT, and extreme hyperglycemia (> 300 mg/dL) is common during the neohepatic phase. Only a few retrospective studies have examined the relationship between intraoperative hyperglycemia and post-transplant complications, with reports of infectious complications or mortality. However, no prospective studies have been conducted regarding the influence of intraoperative hyperglycemia in LT on post-transplant outcome. In addition to absolute blood glucose values, the temporal patterns in blood glucose levels during LT may serve as prognostic features. Persistent neohepatic hyperglycemia (without a decline) throughout LT is a useful
