    Renal dysfunction occurs commonly in patients awaiting orthotopic liver transplantation (OLT) for end-stage liver disease. The use of simultaneous liver-kidney transplantation has increased in the MELD scoring era. As patients may recover renal function after OLT, identifying factors predictive of renal recovery is a critical issue, especially given the scarcity of available organs. Employing the UNOS database, we sought to identify donor- and patient-related predictors of renal recovery among 1720 patients with pre-OLT renal dysfunction and transplanted from 1989 to 2005. Recovery of renal function post-OLT was defined as a composite endpoint of serum creatinine (SCr) ≤1.5 mg/dL at discharge and survival ≥29 days. Pre-OLT renal dysfunction was defined as any of the following: SCr ≥2 mg/dL at any time while awaiting OLT or need for renal replacement therapy (RRT) at the time of registration and/or OLT. Independent predictors of recovery of renal function post-OLT were absence of hepatic allograft dysfunction, transplantation during MELD era, recipient female sex, decreased donor age, decreased recipient ALT at time of OLT, decreased recipient body mass index at registration, use of anti-thymocyte globulin as induction therapy, and longer wait time from registration. Contrary to popular belief, a requirement for RRT, even for prolonged periods in excess of 8 weeks, was not an independent predictor of failure to recover renal function post-OLT. These data indicate that the duration of renal dysfunction, even among those requiring RRT, is a poor way to discriminate reversible from irreversible renal dysfunction.

    Hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) is an indication for orthotopic liver transplantation (OLT) in patients with tumor stage within the United Network for Organ Sharing criteria. The number of patients listed for HBV-related HCC is increasing, while the number of patients listed for HBV-related cirrhosis is declining presumptively because of the availability of more effective oral nucleos(t)ide analogues. This study presents the final, long-term outcome of patients transplanted for HBV-related HCC in the National Institutes of Health (NIH) HBV OLT Study Group. Ninety-eight patients (52.4%) in the NIH HBV OLT cohort underwent OLT for HBV-related HCC. With a mean follow-up of 36.5 months post-OLT, 12 (12.2%) patients developed recurrence of HCC. Multivariate analysis did not find a statistically significant role of gender, tumor stage at OLT, pre-OLT HCC treatment, recurrence of HBV, or duration of HCC diagnosis pre-OLT in predicting HCC recurrence. Serum alpha-fetoprotein (AFP) level >200 ng/mL at transplant was found to be statistically significant in predicting HCC recurrence (p=0.003). HCC recurrence was significantly associated with decreased post-OLT survival. HCC is the most common indication for OLT in patients with chronic hepatitis B in the era of more effective oral antivirals. Serum AFP at the time of OLT is significantly associated with HCC recurrence. © 2010 John Wiley & Sons A/S.

    Pregnancy and parenting have been part of human life throughout history and liver transplant recipients are not any exception. This paper reports successful pregnancies in two liver transplant recipients in Iran. The first case was a 34-year old woman who had undergone orthotopic liver transplantation (OLT) at Shiraz Namazi Educational Hospital in 2002. She decided to get pregnant seven years after the operation. During pregnancy, immunosuppressive therapy continued, except Mycophenolate Mofetil which has an absolute contra-indication in pregnancy. The patient was followed up during pregnancy by the transplant team as well as a gynecologist. She faced no significant complications and the liver function was stable during pregnancy. She later underwent a Cesarean section in the 38(th) week of gestation and the newborn was a healthy girl weighing 2480g with an Apgar score of 8 at the time of birth. There were no evidences of prematurity or structural abnormalities in the newborn. The second case was a 31-year old primipara who had received an orthotopic liver transplant (OLT) in Shiraz in 2002. She had a smooth pregnancy without any complications and the newborn was a boy weighing 3100g with Apgar scores of 8 and 10 at the time of birth and 5 minutes thereafter, respectively. As the number of transplant recipients is growing along with the number of recipients who are in their fertility years, it is vital to ensure a proper medical care by a coordinated multidisciplinary team during pregnancy.

    Sound information is lacking about the clinical presentation of cryptogenic cirrhosis and its outcome after orthotopic liver transplantation (OLT). Among 856 patients who have been transplanted at our center, 40 patients had no evidence of any known etiologies and were therefore defined as suffering from cryptogenic cirrhosis. Their median follow-up period before OLT was 78 months (range, 1-264), and after OLT 97 months (range, 1-132). Laboratory and histological data were evaluated according to features being compatible either with a toxic, hepatitic, or cholestatic condition. The clinical and histological findings differed specifically between these three groups. The toxic-like group (GGT 4-18 x upper limit of normal [ULN]) expressed significantly higher IgA levels, had histologically more often fatty liver changes, and risk factors for non-alcoholic steatohepatitis predominated (56% compared with 3% in the other groups, P=0.01). The hepatitic-like group (ALT 2-18 x ULN) showed histologically features of chronic hepatitis or hepatitic cirrhosis, and only among these patients a median International Autoimmune Hepatitis (IAH) score of 13 was found suggesting autoimmune hepatitis (AiH). In the cholestatic group (AP 2-8 x ULN) histology was compatible with a non-toxic inflammatory process but IAH score excluded AiH in all. After OLT, actuarial graft and patients survival was 90% at 5 years. Mild or moderate graft hepatitis occurred in 9 patients (23%) and was significantly associated with a pre-OLT IAH score >or= 10 (P =0.008). This study provides arguments that cryptogenic cirrhosis is a heterogeneous disease in which autoimmune mechanisms might be predominately involved and being responsible for recurrence of chronic liver disease observed in some instances after OLT.

  6. Management of end stage liver disease (ESLD): what is the current role of orthotopic liver transplantation (OLT)?

    Liver disease due to chronic hepatitis B and C is now a leading cause of morbidity and mortality among HIV-infected patients in the developed world, where classical opportunistic complications of severe immunodeficiency have declined dramatically. Orthotopic liver transplantation (OLT) is the only therapeutic option for patients with end-stage liver disease (ESLD). Accumulated experience in North America and Europe in the last 5 years indicates that 3-year survival in selected HIV-infected recipients of liver transplants was similar to that of HIV-negative recipients. So, HIV infection by itself is not therefore a contraindication for liver transplantation. As survival of HIV-infected patients with ESLD is shorter than non-HIV-infected population, the evaluation for OLT should be made after the first liver decompensation. The current selection criteria for HIV-positive transplant candidates include: no history of opportunistic infections or HIV-related neoplasms, CD4 cell count > 100 cells/mm(3), and plasma HIV viral load suppressible with antiretroviral treatment. For drug abusers, a 2-year abstinence from heroin and cocaine is required, although patients can be in a methadone programme. The main problems in the post-transplant period are pharmacokinetic and pharmacodynamic interactions between antiretrovirals and immunosuppressive drugs, and the management of relapse of HCV infection. Up to now, experience with pegylated interferon and ribavirin is scarce in this population. Currently, HCV re-infection is the main cause for concern.

  7. Orthotopic liver transplantation (OLT): contribution of imaging and interventional radiology in preparing the transplantation and managing complications. Part 2: post-OLT complications and their treatment

    Despite standardisation of the surgical technique and refinement of immunosuppressive therapy, life-threatening complications are still frequent after orthotopic liver transplantation (OLT). These are caused by a number of factors: patients usually reach the day of the transplant in a debilitated condition, they undergo a complex surgical operation and then receive immunosuppressive therapy to prevent rejection. Post-OLT complications therefore usually have a nonspecific clinical presentation, which makes the role of imaging crucial for identifying and differentiating among the various possible clinical scenarios. The most common complications are rejection, vascular thrombosis or stenosis, biliary obstruction or leakage, infarction or haemorrhage, abscesses and, at a later stage, recurrence of the primary disease. If identified early on, some of these complications can be resolved by surgery or interventional radiology, thereby preventing irreversible damage to the graft that would require a repeat transplant or lead the patient to death. During the follow-up of the transplant patient, imaging enables: a) monitoring of the vascular (arterial, portal and hepatic) and biliary anastomoses to assess and treat possible complications; b) identification of conditions related to immunosuppressive therapy (infections or abscesses); c) identification of possible development of tumours or disease recurrence. In the immediate post-OLT period the patient is normally monitored by ultrasound and Doppler-ultrasound, carried out both immediately after the operation to evaluate the patency of the vascular anastomoses, and at the patient's bedside in the ICU unit during the first 24 hours and daily for the first week. If the sonographic findings are positive or there is a strong clinical suspicion of vascular complications, the patient is first studied by the less invasive techniques (CT-angiography and MR-angiography), reserving a confirmatory role for angiographic techniques

    The aim of the study is revelation of postperfusion syndrome (pPS) predictors in orthotopic liver transplantation (OLT). Was conducted a retrospective analysis of anesthesia maintainance protocols during orthotopic liver transplantation in 261 patients aged from 6 months to 60 years. Investigated the effect of various factors on the development of PPS by the application of methods of non-parametric statistics. Significantly more frequent development of the PPS is noted in the age group from 3 to 18 years (up to 30% of patients). In recipients older than 18 years the frequency of the development of the PPS does not depend on age, with an average of 14%. The development of the PPS does not depend on the recipient sex, the nature of the pathology which served as an indication to the OTP, the initial severity of the state, type of OTP (living related donor or cadaveric transplantation, primary or re-transplantation), the transplant warm ischemia duration, use, or the lack of venous-venous bypass, metabolic status of the patient. The obtained results do not contradict to the data of foreign publications. Among parameters available for screening, predictor of PPS was not detected.

    Cardiovascular disease (CVD) complications are important causes of morbidity and mortality after orthotopic liver transplantation (OLT). There is currently no preoperative risk-assessment tool that allows physicians to estimate the risk for CVD events following OLT. We sought to develop a point-based prediction model (risk score) for CVD complications after OLT, the Cardiovascular Risk in Orthotopic Liver Transplantation risk score, among a cohort of 1,024 consecutive patients aged 18-75 years who underwent first OLT in a tertiary-care teaching hospital (2002-2011). The main outcome measures were major 1-year CVD complications, defined as death from a CVD cause or hospitalization for a major CVD event (myocardial infarction, revascularization, heart failure, atrial fibrillation, cardiac arrest, pulmonary embolism, and/or stroke). The bootstrap method yielded bias-corrected 95% confidence intervals for the regression coefficients of the final model. Among 1,024 first OLT recipients, major CVD complications occurred in 329 (32.1%). Variables selected for inclusion in the model (using model optimization strategies) included preoperative recipient age, sex, race, employment status, education status, history of hepatocellular carcinoma, diabetes, heart failure, atrial fibrillation, pulmonary or systemic hypertension, and respiratory failure. The discriminative performance of the point-based score (C statistic = 0.78, bias-corrected C statistic = 0.77) was superior to other published risk models for postoperative CVD morbidity and mortality, and it had appropriate calibration (Hosmer-Lemeshow P = 0.33). The point-based risk score can identify patients at risk for CVD complications after OLT surgery (available at www.carolt.us); this score may be useful for identification of candidates for further risk stratification or other management strategies to improve CVD outcomes after OLT.

    Hernias after orthotopic liver transplant (OLT) occur in about 30 % of cases. Predisposing factors in liver cirrhotic patients of cases are ascites, low abdominal muscle mass and cachexia before and immunosuppression after OLT. Standard operative transplant-technique even in small hernias is to implant a mesh. For patients after liver transplantation a porcine non-cross linked biological patch being less immunogenic than synthetic and cross-linked meshes is chosen for ventral incisional hernia repair. 3 patients (1 female, 2 male), OLT indications Hepatitis C, exogenous- toxic cirrhosis, median-age 53 (51 - 56) and median time to hernia occurrence after OLT were 10 month (6 - 18 m) are documented. 2 patients suffered from diabetes, 2 from chronic-obstructive lung disease. Maintenance immunosuppressions were Everolimus in 1 patient, Everolimus + MMF in the second and Everolimus +Tacrolimus in the third patient. The biological was chosen for hernia repair due to the preexisting risk- factors. Meshes, 10 × 16 cm were placed, in IPOM (Intra-Peritonel-Onlay-Mesh) -position by relaparatomy. Insolvable, monofile, interrupted sutures were used. All patients recovered primarily, and were dismissed within 10 d post OP. No wound healing disorders or signs of postoperative infections occurred. All are free of hernia recurrence in a mean observation time of 22 month (10 - 36). The usage of porcine non-cross-linked biological patches seems feasible for incisional hernia repair after OLT. Wound infections in these patients have been observed with other meshes. Further investigation is needed to prove potential superiority of this biological to the other meshes. © Georg Thieme Verlag KG Stuttgart · New York.

    Anastomotic biliary strictures (AS) after orthotopic liver transplantation (OLT) belong to the most common biliary complications and cause the biggest morbidity burden after OLT. Metal stents for benign biliary strictures are gaining acceptance with many published series. Traditional metal stent designs seem to have poor durability in AS after OLT. Novel intra-ductal stents are showing promise in these strictures. As a result, we designed a special stent with an antimigration waist and a short stent length with a long removal string that rests in the duodenum for easy removal. This is a retrospective multi-centre Australian study of AS after OLT treated with a novel intra-ductal fully covered self-expanding metal stent. From August 2008 to October 2014, records from three liver transplant centres were reviewed. Totally 36 ID-FCSEMS were inserted in 31 cases to treat an AS after OLT. The mean age of the patients was 56 years, and 61 % were male. The mean time of AS presentation after OLT was 20.3 months. Eight out of our 31 patients were previously treated using multiple plastic stenting over time without any success. Treatment with the ID-FCSEMS was performed with an average treatment time of 3.8 months. Stricture resolution was achieved in 100 %. All attempted stents removals were successful without any difficulty. Complications were reported in 6.5 %. It was pleasing that only one case of stent migration (2.8 %) was seen. Follow-up showed seven cases of AS recurrence (24.1 %), and all were treated successfully with repeat ERCP and stenting (some metal, some plastic). This novel ID-FCSEMS has a high clinical success and low complication rate, and in particular, there was only one case of stent migration. As a result, this stent type is preferred to traditional metal stents for treating AS after OLT.

    Liver transplantation represents the first choice treatment for patients with fulminant acute hepatitis and for patients with chronic liver disease and advanced functional failure. Patients in the waiting list for liver transplantation are classified according to the severity of their clinical conditions (evaluated using staging systems mostly based on hematochemical parameters related to liver function). This classification, together with the blood group and the body size compatibility, remains the main criterion for organ allocation. The main indications for liver transplantation are cirrhosis (mainly HCV-, HBV- and alcohol-related) and hepatocellular carcinoma emerging in cirrhosis in adult patients, biliary atresia and some inborn errors of metabolism in pediatric patients. In adults the overall 5-year survival ranges between 60 and 70%, in both American and European series. Even better results have been reported for pediatric patients: in fact, the 5-year survival rate for children ranges between 70 and 80% in the main published series. In this study we evaluated the main medical problems correlated with liver transplantation such as immunosuppressive treatment, acute and chronic rejection, infectious complications, the recurrence of the liver disease leading to transplantation, and cardiovascular and metabolic complications.

    Cadaveric liver transplantation (5-year survival >80%) represents the standard of care for end-stage liver disease (ESLD). Because the demand for cadaveric organs exceeds their availability, living-donor liver transplantation has gained increasing acceptance. Our aim was to assess the marginal cost-effectiveness of cadaveric and living-donor orthotopic liver transplantation (OLT) in adults with ESLD. Using a Markov model, outcomes and costs of ESLD treated (1) conservatively, (2) with cadaveric OLT alone, and (3) with cadaveric OLT or living-donor OLT were computed. The model was validated with published data. The case-based scenario consisted of data on all 15 ESLD patients currently on our waiting list (3 women, 12 men; median age, 48 years [range, 33-59 years]) and on the outcome of all OLT performed for ESLD at our institution since 1995 (n=51; actuarial 5-year survival 93%). Living-donor OLT was allowed in 15% during the first year of listing; fulminant hepatic failure and hepatocellular carcinoma were excluded. Cadaveric OLT gained on average 6.2 quality-adjusted life-years (QALYs) per patient compared with conservative treatment, living-donor OLT, an additional 1.3 QALYs compared with cadaveric OLT alone. Marginal cost-effectiveness of a program with cadaveric OLT alone and a program with cadaveric and living-donor OLT combined were similar (E 22,451 and E 23,530 per QALY gained). Results were sensitive to recipient age and postoperative survival rate. Offering living-donor OLT in addition to cadaveric OLT improves survival at costs comparable to accepted therapies in medicine. Cadaveric OLT and living-donor OLT are cost-effective.

    Full Text Available BACKGROUND: Orthotopic liver transplantation (OLT includes the implantation of partial or complete liver graft from a living or deceased donor into the recipient. The purpose of this study is to analyze health associated quality of life among OLT recipients. METHODS: This study was conducted at a tertiary care center from January 2011 to January 2015. The quality of life questionnaire was completed before OLT and 6 months after OLT by 32 patients. RESULTS: Mean age of liver transplant recipients was 45±11 years, body mass index (BMI was 24.2±4.2 kg/m2 and 28/32 (87.5% patients were males. Good health was reported by 96.9% after OLT in contrast to 81.2% patients before OLT (p=0.0001. Vigorous exercise capability was 40.6% after OLT in contrast to 28.1% before OLT (P=0.43. CONCLUSION: We found a significant increase in quality of life scores among patients who underwent OLT. However, compared to pre-OLT, recipient’s participation in vigorous activities did not change 6 months after OLT.

    Renal dysfunction frequently occurs during the periods preceding and following orthotopic liver transplantation (OLT), and in many cases, renal replacement therapy (RRT) is required. Information regarding the duration of RRT and the rate of kidney function recovery after OLT is crucial for transplant program management. We evaluated a sample of 155 stable patients undergoing post-intensive care hemodialysis (HD) from a patient population of 908 adults who underwent OLT. We investigated the average time to renal function recovery (duration of RRT required) and determined the risk factors for remaining on dialysis > 90 days after OLT. Log-rank tests were used for univariate analysis, and Cox proportional hazards models were used to identify factors associated with the risk of remaining on HD. The results of our analysis showed that of the 155 patients, 28% had pre-OLT diabetes mellitus, 21% had pre-OLT hypertension, and 40% had viral hepatitis. Among the patients, the median MELD (Model for End-Stage Liver Disease) score was 27 (interquartile range [IQR] 22-35). When they were listed for liver transplantation, 32% of the patients had serum creatinine (Scr) levels > 1.5 mg/dL or were on HD, and 50% had serum creatinine (Scr) levels > 1.5 mg/dL or were on HD at the time of OLT. Of the transplanted patients, 25% underwent pre-OLT intermittent HD, and 14% and 41% underwent continuous renal replacement therapy (CRRT) pre-OLT and post-OLT, respectively. At 90 days post-OLT, 118 (76%) patients had been taken off dialysis, and 16 (10%) patients had died while undergoing HD. The median recovery time of these post-OLT patients was 33 (IQR 27-39) days. In the multivariate analysis, fulminant hepatic failure as the cause of liver disease (prenal function after OLT, and those who were diagnosed with fulminant hepatic failure, had no pre-OLT hypertension, received a lower transfused volume of intraoperative FFP and did not undergo pre-OLT intermittent HD had a higher probability

    Obesity is frequently encountered in patients with orthotopic liver transplant (OLT). The role of bariatric surgery is still unclear for this specific population. The aim of this study was to review our experience with laparoscopic sleeve gastrectomy (LSG) after OLT. We performed a retrospective case-control study of patients undergoing LSG after OLT from 2010 to 2016. OLT-LSG patients were matched by age, sex, body mass index (BMI), and year to non-OLT patients undergoing LSG. Demographics, operative variables, postoperative events, and long-term weight loss with comorbidity resolution were collected and compared between cases and controls. Of 303 patients undergoing LSG, 12 (4%) had previous OLT. They were matched to 36 non-OLT patients. No difference was found between groups in the American Society of Anesthesiologists class, mean operative time, or postoperative morbidity. The non-OLT group, however, had a significantly shorter mean hospital stay than the OLT group (1.7 vs 3.1 days; P OLT patients had significantly more excess body weight loss at 2 years (53.7 vs 45.2%; P OLT in appropriately selected patients appears to have similar outcomes to LSG in non-OLT patients.

    Orthotopic liver transplantation (OLT) is the best treatment option for selected patients with hepatocellular carcinoma (HCC) with the background of cirrhosis since this treatment modality can cure both diseases at once. Over the years, the applicability of OLT for HCC has evolved. In Asia, including Hong Kong, a shortage of deceased donor liver grafts is a universal problem having to be faced in all transplant centers. Living-donor liver transplant (LDLT) has therefore been developed to counteract organ shortage and the high prevalence of HCC. The application of LDLT for HCC is a complex process involving donor voluntarism, selection criteria for the recipient and justification with respect to long-term survival in comparison to the result of deceased donor liver transplant. This article reviews the authors' experience with OLT for HCC patients in Hong Kong, with emphasis on the applicability and outcome of LDLT for HCC. Donor voluntarism has a significant impact on the application of LDLT. "Fast-track" LDLT in the setting of recurrence following curative treatment carries a high risk of recurrence even though the tumor stage fulfills the standard criteria. Although the survival outcome may be worse following LDLT than DDLT for HCC, LDLT is still the main treatment option for patients with transplantable HCC in Hong Kong, and a reasonable survival outcome can be achieved in selected patients with extended indications. It is particularly true that LDLT provides the only hope for patients with advanced HCC under the constricting problem of organ shortage.

    Full Text Available Background. Abnormal liver enzymes postorthotopic liver transplant (OLT may indicate significant biliary pathology or organ rejection. There is very little known in the literature regarding the current role of diagnostic ERCP in this scenario. Aim. To review the utility of diagnostic ERCP in patients presenting with abnormal liver function tests in the setting of OLT. Methods. A retrospective review of diagnostic ERCPs in patients with OLT from 2002 to 2013 from a prospectively maintained, IRB approved database. Results. Of the 474 ERCPs performed in OLT patients, 210 (44.3%; 95% CI 39.8–48.8 were performed for abnormal liver function tests during the study period. Majority of patients were Caucasian (83.8%, male (62.4% with median age of 55 years (IQR 48–62 years. Biliary cannulation was successful in 99.6% of cases and findings included stricture in 45 (21.4 %; biliary stones/sludge in 23 (11%; biliary dilation alone in 31 (14.8%; and normal in 91 (43.3%. Three (1.4% patients developed mild, self-limiting pancreatitis; one patient (0.5% developed cholangitis and two (1% had postsphincterotomy bleeding. Multivariate analyses showed significant association between dilated ducts on imaging with a therapeutic outcome. Conclusion. Diagnostic ERCP in OLT patients presenting with liver function test abnormalities is safe and frequently therapeutic.

    Full Text Available Abstract Objective Orthotopic-liver-transplantation (OLT in patients with Human-Immunodeficiency-Virus infection (HIV and end-stage-liver-disease (ESDL is rarely reported. The purpose of this study is to describe our institutional experience on OLT for HIV positive patients. Material and methods This is a retrospective study of all HIV-infected patients who underwent OLT at the University Hospital of Essen, from January 1996 to December 2009. Age, sex, HIV transmission-way, CDC-stage, etiology of ESDL, concomitant liver disease, last CD4cell count and HIV-viral load prior to OLT were collected and analysed. Standard calcineurin-inhibitors-based immunosuppression was applied. All patients received anti-fungal and anti-pneumocystis carinii pneumonia prophylaxis post-OLT. Results Eight transplanted HIV-infected patients with a median age of 46 years (range 35-61 years were included. OLT indications were HCV (n = 5, HBV (n = 2, HCV/HBV/HDV-related cirrhosis (n = 1 and acute liver-failure (n = 1. At OLT, CD4 cell-counts ranged from 113-621 cells/μl, and HIV viral-loads from Conclusions OLT in HIV-infected patients and ESLD is an acceptable therapeutic option in selected patients. Long-term survival can be achieved without HIV disease-progression under antiretroviral therapy and management of the viral hepatitis co-infection.

    Our purpose was to assess the feasibility of orthotopic liver transplantation (OLT) in patients priorly having undergone transjugular intrahepatic portosystemic shunt (TIPS) with an expanded tetrafluoroethylene (e-PTFE)-covered endoprosthesis. In 48 patients an e- PTFE-covered endoprosthesis was inserted to treat severe complications of portal hypertension. In 36 patients the endoprosthesis was inserted during TIPS creation (de novo TIPS); in the other 12 patients the endoprosthesis was placed to repermeabilize the previously created, but occluded bare stent (revision TIPS). Eight of them (5 de novo and 3 revision cases) later underwent an OLT. The hospital records of these patients were reviewed from initial admission, through TIPS, the pre-OLT period, and OLT to current postoperative status. Five de novo and 3 revision cases underwent OLT 4-279 days (mean delay: 80.8 days) after TIPS procedure. All OLT's were performed under veno-venous bypass surgery. De visu surgical inspection confirmed correct positioning of the fully patent stent graft, starting in the portal vein and ending at the junction of the hepatic vein to the inferior caval vein. No surgical difficulty was observed during proximal or distal clamping or during resection of the diseased liver. Correctly positioned e-PTFE-covered nitinol endoprostheses do not interfere with a later OLT and may not be considered as a contraindication in patients who need a TIPS as a bridge to OLT

    With the introduction of orthotopic liver transplantation (OLT) almost 40 years ago, changes in the cardiovascular system that manifest during the different phases of the operation combined, sometimes with massive hemorrhage in likely critically ill patients have been a challenge. Here hemodynamic...... monitoring of the patients during OLT is addressed with focus on maintaining the patients' central blood volume (CBV) and methods and devices that can serve that purpose are listed. It is considered that a stable CBV maintains cerebral blood flow and oxygenation and thereby the well-being of the patient......, while even a small reduction in blood pressure affects cerebral blood flow and oxygenation if it reflects a reduced CBV and thereby cardiac output. In that regard it is accepted that for the patient going through OLT cardiac output (~8 L/min-1) and also venous oxygen saturation (~85%) are larger than...

    Full Text Available Objectives. This summary evaluates the outcomes of orthotopic liver transplantation (OLT of HIV-positive patients in Germany. Methods. Retrospective chart analysis of HIV-positive patients, who had been liver-transplanted in Germany between July 1997 and July 2011. Results. 38 transplantations were performed in 32 patients at 9 German transplant centres. The reasons for OLT were end-stage liver disease (ESLD and/or liver failure due to hepatitis C (HCV (=19, hepatitis B (HBV (=10, multiple viral infections of the liver (=2 and Budd-Chiari-Syndrome. In July 2011 19/32 (60% of the transplanted patients were still alive with a median survival of 61 months (IQR (interquartile range: 41–86 months. 6 patients had died in the early post-transplantation period from septicaemia (=4, primary graft dysfunction (=1, and intrathoracal hemorrhage (=1. Later on 7 patients had died from septicaemia (=2, delayed graft failure (=2, recurrent HCC (=2, and renal failure (=1. Recurrent HBV infection was efficiently prevented in 11/12 patients; HCV reinfection occurred in all patients and contributed considerably to the overall mortality. Conclusions. Overall OLT is a feasible approach in HIV-infected patients with acceptable survival rates in Germany. Reinfection with HCV still remains a major clinical challenge in HIV/HCV coinfection after OLT.

    Full Text Available Background: Neurological complications are common after orthotopic liver transplantation (OLT. We aimed to characterize the risk factors associated with neurological complications and mortality among patients who underwent OLT in the post-model for end-stage liver disease (MELD era.Methods: In a retrospective review, we evaluated 227 consecutive patients at the Keck Hospital of the University of Southern California before and after OLT to define the type and frequency of and risk factors for neurological complications and mortality.Results: Neurological complications were common (n=98, with encephalopathy being most frequent (56.8%, followed by tremor (26.5%, hallucinations (11.2%, and seizure (8.2%. Factors associated with neurological complications after OLT included preoperative dialysis, hepatorenal syndrome, renal insufficiency, intra-operative dialysis, preoperative encephalopathy, preoperative mechanical ventilation, and infection. Preoperative infection was an independent predictor of neurological complications (OR 2.83, 1.47 – 5.44. One-month mortality was 8.8% and was independently associated with urgent re-transplant, preoperative intubation, intraoperative arrhythmia, and intraoperative use of multiple pressors.Conclusion: Neurological complications are common in patients undergoing OLT in the post-MELD era, with encephalopathy being most frequent. An improved understanding of the risk factors related to both neurological complications and one-month mortality post-transplantation can better guide perioperative care and help improve outcomes among OLT patients.

    1998-01-01

    Purpose: To assess the results of radiological treatment of patients with hepatocellular carcinoma (HCC) performed before orthotopic liver transplantation (OLT). Methods: Sixty-two transplanted patients with a total of 89 HCC nodules were studied; 50 lesions in 38 patients had been treated prior to OLT with transcatheter arterial chemoembolization (TACE; n= 29), percutaneous ethanol injection (PEI; n= 10), or combined therapy (TACE + PEI; n= 11). The induced necrosis was pathologically evaluated. The recurrence rate after OLT in the treated group of patients (n= 38) was compared with that in the non-treated group (n= 24). Results: After TACE, necrosis was complete in 7 of 29 lesions (24.1%), partial in 11 of 29 (37.9%), and absent in 11 of 29 (37.9%). After PEI, necrosis was complete in 8 of 10 lesions (80%), and partial in 2 of 10 (20%). Using combined therapy, necrosis was complete in 11 of 11 lesions (100%). Four of 24 untreated and 4 of 38 treated patients did not survive OLT from causes not related to the HCC; 3 of 20 non-treated patients (15%) and 4 of 34 treated patients (11.8%) had post-OLT recurrence (these last four patients had undergone only TACE and did not have tumor necrosis at pathological examination). Conclusion: TACE of HCC prior to OLT had no influence on the recurrence rate. PEI and combined therapy (TACE + PEI) may be recommended in patients awaiting OLT

    Thomas W. Faust

    1997-01-01

    Full Text Available Recurrent variceal bleeding in liver transplant candidates with end-stage liver disease can complicate or even prohibit a subsequent transplant procedure (OLT. Endoscopic sclero-therapy and medical therapy are considered as first-line management with surgical shunts reserved for refractory situations. Surgical shunts can be associated with a high mortality in this population and may complicate subsequent OLT. The transjugular intrahepatic portosystemic shunt (TIPS has been recommended in these patients as a bridge to OLT. This is a new modality that has not been compared with previously established therapies such as the distal splenorenal shunt (DSRS. In this study we report our experience with 35 liver transplant recipients who had a previous TIPS (18 patients or DSRS (17 patients for variceal bleeding. The TIPS group had a significantly larger proportion of critically ill and Child-Pugh C patients. Mean operating time was more prolonged in the DSRS group (P=0.014 but transfusion requirements were similar. Intraoperative portal vein blood flow measurements averaged 2132±725 ml/min in the TIPS group compared with 1120±351ml/min in the DSRS group (P<0.001. Arterial flows were similar. Mean ICU and hospital stays were similar. There were 3 hospital mortalities in the DSRS group and none in the TIPS group (P=0.1. We conclude that TIPS is a valuable tool in the management of recurrent variceal bleeding prior to liver transplantation. Intra0Perative hemodynamic measurements suggest a theoretical advantage with TIPS. In a group of patients with advanced liver disease we report an outcome that is similar to patients treated with DSRS prior to liver transplantation. The role of TIPS in the treatment of nontransplant candidates remains to be clarified.

    Health-related quality of life (HRQOL) following orthotopic liver transplantation (OLT) has become increasingly important. Therefore, we aimed to identify factors affecting HRQOL after OLT. This cross-sectional, single-centre study surveyed 281 OLT patients. Survey tools included the Short Form (SF-36) Health Survey, the Patient Health Questionnaire 9 (PHQ9), and a self-designed employment questionnaire. Patient medical records were reviewed. Participants included 187 men (mean age at OLT: 50 [± 11; 13-69] years). Primary indications for OLT were viral hepatitis (28%), alcoholic liver disease (35%), cholestatic liver disease (11%), and others (26%). Follow-up ranged from 2 to 136 months. Clinical factors associated with improved HRQOL were age ≤ 45 years at OLT and current MELD score <=≤ 13. Time after OLT and indication for transplantation affected SF-36 HRQOL. SF-36 physical component summary scales plateaued at 3-years post-OLT and then stabilized. For the SF-36 HRQOL, scores were the lowest in all domains for OLT recipients transplanted for chronic viral hepatitis and for unemployed patients, whereas sex and number of transplantations showed no significant differences. The PHQ9 results showed that depression was significantly more frequent among patients with current MELD score ≥ 13 or impaired liver function and those transplanted for chronic viral hepatitis or unemployed patients. Age and sex did not influence PHQ9 results. Medical and psychosocial support is crucial for long-term HRQOL after OLT. Developing multidisciplinary interventions to address issues such as employment, age, MELD score, and liver function may improve long-term HRQOL in these patients.

    To explore the effect of orthotopic liver transplantation (OLT) on portal hypertension by observing the radiological changes of splenic volume and collaterals before and after OLT. In our hospital 56 patients performing OLT due to cirrhosis, portal hypertension and splenomegaly were classified into five groups according to their following-up time: A (≤3 months), B (>3-6 months), C (>6-12 months), D (>12-24 months), and E (>24 months). Twenty health people were chose as control group (F). The splenic width, thickness, length, volume, diameter of portal and splenic vein and collaterals were measured and observed in every patient of six groups before and after OLT respectively. After OLT, the splenic volume decreased by 25.4%, 27.8%, 21.9%, 25.2%, 27.7% in five groups respectively, which was still larger than the normal group (POLT. The opened umbilical vein disappeared and the retroperitoneal varices persisted in five cases after OLT. Splenomegaly and opened collaterals can be relieved by OLT effectively. The splenic volume didn't change obviously until it decreased by 25% in the three months after OLT. Gastroesophageal varices can be removed in most of patients after OLT. The splenomegaly could last paralled with the splenic vein and retroperitoneal varices after OLT. After OLT, correct disposal of splenic and collateral changes could improve the success rate and the long-term treatment effect of OLT.

    Complimentary to orthotopic liver transplantation (OLT), living donor liver transplantation (LDLT) is increasingly considered a therapeutic option in the therapy of end-stage liver disease. Accurate pre- and postoperative imaging is crucial for the transplantation success and represents an established part of the current evaluation algorithms. This article summarizes the most important requirements and the current imaging standards. Preoperative imaging is important for exclusion of transplantation contraindications in the recipient and for reliable assessment of anatomical variants in the donor. The main purpose of postoperative imaging is the early detection and characterization of complications. In both instances, multislice CT currently represents the most versatile and reliable imaging modality, still superior to MRI. For postoperative follow-up, the imaging modality of first choice is still bedside ultrasound; however, unclear findings usually need to be further assessed by CT. (orig.) [de

    We analyze the experience of the Center of General Surgery and Liver Transplantation from the Fundeni Clinical Institute (Bucharest, Romania) regarding orthotopic liver transplantation (OLT) in adult recipients, with whole liver grafts from cadaveric donors, between April 2000 (when the first successful LT was performed in Romania) and December 2004. This series includes 37 OLTs in adult recipients (16 women and 21 men, aged between 29-57 years--average 46 years). Other two LT with whole liver cadaveric grafts and two reduced-size LT were performed in children; also, in the same period, due to the acute organ shortage, other methods of LT were performed in 28 patients (21 living donor LT, 6 split LT and one "do mino" LT), that were not included in the present series. The indications for OLT were HBV cirrhosis--10, HBV+HDV cirrhosis--4, HCV cirrhosis--11, HBV+HCV cirrhosis--2, biliary cirrhosis--5, Wilson disease--2, alcoholic cirrhosis--1, non-alcoholic liver disease--1, autoimmune cirrhosis--1. With three exceptions, in which the classical transplantation technique was used, the liver was grafted following the technique described by Belghiti. Local postoperative complications occurred in 15 patients (41%) and general complications in 17 (46%); late complications were registered in 18 patients (49%) and recurrence of the initial disease in 6 patients (16%). Intrao- and postoperative mortality was 8% (3/37). There were two patients (5%) who died because of immunosuppressive drug neurotoxicity at more than 30 days following LT. Four patients (11%) died lately because of PTLD, liver venoocclusive disease, recurrent autoimmune hepatitis and liver venoocclusive disease, myocardial infarction, respectively. Thirty-four patients survived the postoperative period (92%); according to Kaplan-Meier analysis, actuarial patient-survival rate at month 31 was 75%.

    The aim of the paper is to evaluate MR imaging and dynamic CT as noninvasive procedures to image signs of graft failure after an orthotopic liver transplantation (OLT). Thirty MR studies and 50 dynamic CT examinations were performed within 20 days after OLT. MR examinations were performed with a 0.5-T Siemens Magnetom. CT scans were obtained by using a Siemens Somatom Plus. In all patients, MR images demonstrated a perivascular rim of intermediate signal intensity on T1-weighted and increased signal intensity on T2-weighted images in the hilum of the liver; in 20/26, this was seen in peripheral areas also. In all patients, a perivascular area of low attenuation was diagnosed at angio-CT

    Each year, 5000-6000 individuals undergo orthotopic liver transplantation (OLT) in the United States, and of these, nearly 18% have alcoholic liver disease. Relapse to alcohol occurs in more than 40% of patients with OLT for alcoholic liver disease. We sought to identify factors that predict relapse to alcohol or medication nonadherence following OLT in patients with alcoholic liver disease and to review what randomized clinical interventions have addressed these factors following OLT. Our hypothesis was that there would be factors before and after OLT that predict relapse to alcohol following OLT, and that these, if targeted, might improve sobriety and associated outcomes of adherence with medications and appointments. We performed a review (focusing on articles published since 2004) with PubMed and MEDLINE searches using the following search terms: liver transplantation, recidivism, alcohol relapse, and predictors of alcohol relapse. We supplemented the online searches with manual reviews of article reference lists and selected relevant articles for further review by author consensus. In largely white populations, prospective studies document that shorter length of pretransplantation sobriety is a significant predictor of time to first drink and time to binge use. Presence of psychiatric comorbidity, high score on standardized High-risk Alcoholism Relapse Scale, and diagnosis of Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition) alcohol dependence are predictive of posttransplantation alcohol relapse. Pretransplantation alcohol use history variables (e.g., family history of alcoholism) reliably discriminate between complete abstainers and those who drink, while medical and psychosocial characteristics at early post-liver transplantation period (e.g., more bodily pain) maximally discriminate patterns of alcohol use. Alcoholic individuals with early-onset, rapidly accelerating moderate use and early-onset, continuously increasing heavy use have

    The majority of complications due to orthotopic liver transplantation (OLT)need interventional treatment. For arterial and venous complications after OLT, we have established clear and definite interventional therapeutic mode. However, it has been the difficult point as well as the weak point for interventional radiologists to treat the biliary complications. With the technical improvement and deep-going understanding, a part of biliary complications of OLT can be relieved or even finally be cured with percutaneous biliary drainage (PTBD) and endoscopic nasobiliary drainage (ENBD). For some patients, PTBD and ENBD seem to be the main palliative therapeutic means, which might accompany the patients for a lifetime. Now, it is an urgent demand to formulate the clinical therapeutic guidelines for the treatment of biliary complications after OLT. (authors)

    The shortage of liver donations demands the use of suboptimal grafts with steatosis being a frequent finding. Although ≤30% macrovesicular steatosis is considered to be safe the risk for primary non-function (PNF) and outcome after re-transplantation (re-OLT) is unknown. Among 1205 orthotopic liver transplantations performed at our institution the frequency, survival and reason of re-OLT were evaluated. PNF (group A) cases and those with initial transplant function but subsequent need for re-OLT (group B) were analysed. Histopathology and clinical judgement determined the cause of PNF and included an assessment of hepatic steatosis. Additionally, survival of fatty liver allografts (group C) not requiring re-OLT was considered in Kaplan-Meier and multivariate regression analysis. A total of 77 high urgency re-OLTs were identified and included 39 PNF cases. Nearly 70% of PNF cases were due to primary fatty liver allografts. The 3-month in-hospital mortality for PNF cases after re-OLT was 46% and the mean survival after re-OLT was 0.5 years as compared to 5.2 and 5.1 years for group B, C, respectively, (Phepatic steatosis was associated with an inferior survival (HR 4.272, P=.002). The MELD score, donor BMI, age, cold ischaemic time, ICU stay, serum sodium and transaminases did not influence overall survival. Our study highlights fatty liver allografts to be a major cause for PNF with excessive mortality after re-transplantation. The findings demand the development of new methods to predict risk for PNF of fatty liver allografts. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

  4. Encephalopathy and liver transplantation.

    Liver transplantation (LT) candidates experience frequently episodic or persistent hepatic encephalopathy. In addition, these patients can exhibit neurological comorbidities that contribute to cognitive impairment in the pre-transplant period. Assessment of the respective contribution of hepatic encephalopathy or comorbidities in the cognitive manifestations is critical to estimate the neurological benefits of restoring liver function. Magnetic resonance imaging and spectroscopy are useful to assess the impact of liver failure or comorbidities. This assessment is critical to decide liver transplant in difficult cases. In the early postoperative period, LT is commonly complicated by a confusional syndrome. The possible role of persisting hepatic encephalopathy in its development has not been clearly established. The origin is usually considered multifactorial and relates to complications following LT, such as infections, rejection, primary liver dysfunction, immunosuppressors, etc.… The diagnosis and treatment is based in the recognition of comorbidities and optimal care of metabolic disturbances. Several studies have demonstrated recovery of cognitive function after LT in patients that have exhibited hepatic encephalopathy. However, some deficits may persist specifically among patients with persistent HE. Other factors present before LT that contribute to a worse neuropsychological outcome after LT are diabetes mellitus and alcohol consumption. Long-term after LT, cognitive function may worsen in relation to vascular risk factors.

    Full Text Available Liver transplantation (LT is the only available live-saving procedure for children with irreversible liver failure. This paper reports our experience from the follow-up of 16 Greek children with end-stage liver failure who underwent a LT. Over a period of 15 years, 16 pediatric liver recipients received follow up after being subjected to OLT (orthotopic liver transplantation due to end-stage liver failure. Nine children initially presented with extrahepatic biliary atresia, 2 with acute liver failure after toxic mushroom ingestion, 2 with intrahepatic cholestasis, 2 with metabolic diseases and one with hepatoblastoma. Ten children received a liver transplant in the Organ Transplantation Unit of Aristotle University of Thessaloniki and the rest in other transplant centers. Three transplants came from a living-related donor and 13 from a deceased donor. Six children underwent immunosuppressive treatment with cyclo­sporine, mycophenolate mofetil and corticosteroids, and 7 with tacrolimus, mycophenolate mofetil and corticosteroids. Three out of 16 children died within the first month after the transplantation due to post-transplant complications. Three children presented with acute rejection and one with chronic organ rejection which was successfully managed. Five children presented with cytomegalovirus infection, 5 with Epstein-Barr virus, 2 with HSV1,2, 2 with ParvoB19 virus, 2 with varicella-zoster virus and one with C. Albicans infection. One child presented with upper gastrointestinal hemorrhage and one with small biliary paucity. A satisfying outcome was achieved in most cases, with good graft function, except for the patient with small biliary paucity who required re-transplantation. The long-term clinical course of liver transplanted children is good under the condition that they are attended in specialized centers.

    Full Text Available OBJECTIVE: To summarize the experience with salvage liver transplantation (SLT for patients with recurrent hepatocellular carcinoma (HCC after primary hepatic resection in a single center. METHODS: A total of 376 adult patients with HCC underwent orthotopic liver transplantation (OLT at Organ Transplantation Center, the First Affiliated Hospital of Sun Yat-sen University, between 2004 and 2008. Among these patients, 36 underwent SLT after primary liver curative resection due to intrahepatic recurrence. During the same period, one hundred and forty-seven patients with HCC within Milan criteria underwent primary OLT (PLTW group, the intra-operative and post-operative parameters were compared between these two groups. Furthermore, we compared tumor recurrence and patient survival of patients with SLT to 156 patients with HCC beyond Milan criteria (PLTB group. Cox Hazard regression was made to identify the risk factors for tumor recurrence. RESULTS: The median interval between initial liver resection and SLT was 35 months (1-63 months. The intraoperative blood loss (P0.05. When compared to those patients with HCC beyond Milan criteria undergoing primary OLT, patients undergoing SLT achieved a better survival and a lower tumor recurrence. Cox Proportional Hazards model showed that vascular invasion, including macrovascular and microvascular invasion, as well as AFP level >400 IU/L were risk factors for tumor recurrence after LT. CONCLUSIONS: In comparison with primary OLT, although SLT is associated with increased operation difficulties, it provides a good option for patients with HCC recurrence after curative resection.

    Liver transplantation (OLT) for hepatocellular carcinoma (HCC) improves patient survival when tumor size and number are limited according to the Milan criteria. However, the impact of tumor size vs. the number of lesions for tumor recurrence after OLT is unclear. Microvascular invasion appears to be a significant risk factor for tumor recurrence. Therefore, it was the aim of this study to investigate tumor differentiation and microvascular invasion in relation to tumor number and size and their impact on survival after transplantation. In 97 adult HCC patients who underwent OLT between June 1985 and December 2005 the incidence of microvascular invasion, tumor differentiation, and the number and size of tumor lesions were analyzed retrospectively. Their impact on survival was studied by multivariate analysis. Microvascular invasion was the only independent negative predictor of survival after OLT for HCC (p = 0.025). Tumor size > 5 cm was predictive for microvascular invasion (p = 0.007). In contrast, tumor number did not affect the incidence of microvascular invasion or cumulative survival. The size of the largest HCC lesion, but not the number of tumors, determined microvascular invasion, a predictor of the outcome following OLT for HCC. Thus, the number of HCC lesions should not be applied to patient selection prior to OLT. These data support the extension of the Milan criteria for the selection of HCC patients for OLT with regard to tumor number, but not tumor size.

    End-stage liver disease is a major cause of morbidity and mortality among ethnic minorities. In the United States, ethnic minorities comprise approximately 30% of all adult liver transplantations performed annually. Several studies have suggested that ethnic populations differ with respect to access and outcomes in the pre- and post-transplantation setting. This paper will review the existing literature on ethnic variations in the adult liver transplantation population.

    Aim: To assess the value of diffusion-weighted imaging (DWI) in evaluating parenchymal disorders following orthotopic liver transplantation (OLT). Materials and methods: This institutional review board-approved, retrospective study measured the hepatic apparent diffusion coefficients (ADC) in patients following OLT. Those with vascular complications or within 3 months of OLT were excluded. A single-shot echoplanar sequence with b values of 50, 400 (or 500), and 800 s/mm 2 was performed. Liver biopsy specimens [performed with a median of 17 days after magnetic resonance imaging (MRI)] were recorded for the presence and severity of parenchymal disorders, such as acute cellular rejection, and recurrence of fibrosis in all patients, and the recurrence of viral hepatitis in patients with hepatitis C. ADC values were measured blinded to histology in 41 patients (33 males) who had 56 MRI scans. Results: There was a significant difference in ADC values associated with a histological abnormality seen on core biopsy [n = 43, mean (SD) ADC of 0.91 (0.15)x10 -3 mm 2 /s] and those associated with no histological abnormality [n = 13, mean (SD) ADC of 1.11 (0.17)x10 -3 mm 2 /s; (p = 0.003)]. ADC values did not predict any of the individual parenchymal disorders on logistic regression analysis. When the ADC value was -3 mm 2 /s, there was a sensitivity and specificity of 85% and 72%, respectively, in predicting a parenchymal disorder (area under ROC curve = 0.84; 95% CI 0.72 to 0.92). Conclusion: ADC measurements may help in deciding which patients require core liver biopsy after OLT. However, ADC values are not likely to be reliable in differentiating between the various parenchymal disorders.

    The aim of our study was to evaluate our liver transplant pediatric patients and to report our experience in the complications and the long-term follow-up results. Patients between the ages of 0 and 18 years, who had liver transplantation in the organ transplantation center of our university hospital between 1997 and 2016, were included in the study. The age, sex, indications for the liver transplantation, complications after the transplantation, and long-term follow-up findings were retrospectively evaluated. The obtained results were analyzed with statistical methods. In our organ transplantation center, 62 pediatric liver transplantations were carried out since 1997. The mean age of our patients was 7.3 years (6.5 months-17 years). The 4 most common reasons for liver transplantation were: Wilson's disease (n=10; 16.3%), biliary atresia (n=9; 14.5%), progressive familial intrahepatic cholestasis (n=8; 12.9%), and cryptogenic cirrhosis (n=7; 11.3%). The mortality rate after transplantation was 19.6% (12 of the total 62 patients). The observed acute and chronic rejection rates were 34% and 4.9%, respectively. Thrombosis (9.6%) was observed in the hepatic artery (4.8%) and portal vein (4.8%). Bile leakage and biliary stricture rates were 31% and 11%, respectively. 1-year and 5-year survival rates of our patients were 87% and 84%, respectively. The morbidity and mortality rates in our organ transplantation center, regarding pediatric liver transplantations, are consistent with the literature.

    Full Text Available Immune thrombocytopenic purpura (ITP is a rare complication after liver transplantation. Infection with cytomegalovirus (CMV is a frequent complication of organ transplantation and may induce autoimmune diseases, such as ITP. We report a case of ITP after primary CMV infection in a 3-year-old boy recipient of living-related orthotopic liver transplantation (OLT. The ITP developed 2 years after OLT in this patient who had received tacrolimus as an immunosuppressive agent, with nadir platelet counts of 5000/mm3 in 2 weeks. The patient was treated with two courses of intravenous gamma globulin (1 g/kg/day for 2 days and subsequent oral prednisolone (1.3 mg/kg/day for 2 weeks. He recovered from thrombocytopenia 4 weeks later. An inadequate immunosuppression, as evident by the low serum tacrolimus level (5.8 ng/mL before the episode of ITP in this patient, may allow the development of ITP after CMV infection.

    Full Text Available BACKGROUND: Orthotopic liver transplantation (OLT in a well-selected population is a highly successful procedure, with one-year survival rates reported to be as high as 90%. Advanced age is considered to be a contraindication. Survival rates in patients >60 years of age appear to be comparable with those of younger patients. However, little objective data exist on the outcomes of patients >65 years of age undergoing OLT.

    In liver transplant patients with type 2 diabetes mellitus (DM), the disease worsens after transplantation because of longterm use of diabetogenic immunosuppressive drugs, making management of those patients a great challenge. The objective of our study was to evaluate the safety and efficacy of a simplified multivisceral transplantation (SMT) procedure for the treatment of patients with end-stage liver disease and concurrent type 2 DM. Forty-four patients who had pretransplant type 2 DM were included. A total of 23 patients received SMT, and 21 patients received orthotopic liver transplantation (OLT). Patient and graft survivals, complications, diabetic control, and quality of life (QOL) were retrospectively analyzed in both groups. The 1-, 3-, and 5-year cumulative patient and graft survival rates were 91.5%, 75.4%, and 75.4% in the SMT group and were 94.4%, 64.4%, and 64.4% in the OLT group, respectively (P = 0.70). Interestingly, 95.7% (22/23) of patients achieved complete remission from DM after SMT compared with 16.7% (3/18) of patients after OLT. The occurrence of biliary complication was significantly higher in the OLT group than that in the SMT group (23.8% versus 0.0%; P = 0.01). Moreover, better QOL was observed in the SMT group than that in the OLT group. In conclusion, the SMT procedure we described here is a safe and viable option for patients with end-stage live disease and concurrent type 2 DM. This SMT procedure offers excellent transplant outcomes and QOL. Liver Transplantation 23 1161-1170 2017 AASLD. © 2017 by the American Association for the Study of Liver Diseases.

    Although it has been suggested that selective decontamination of the digestive tract (SDD) decreases postoperative aerobic Gram-negative and fungal infections in orthotopic liver transplantation (OLT), no controlled trials exist in pediatric patients. This prospective, randomized controlled study of 36 pediatric OLT patients examines the effect of short-term SDD on postoperative infection and digestive tract flora. Patients were randomized into two groups. The control group received perioperative parenteral antibiotics only. The SDD group received in addition polymyxin E, tobramycin, and amphotericin B enterally and by oropharyngeal swab postoperatively until oral intake was tolerated (6 +/- 4 days). Indications for operation, preoperative status, age, and intensive care unit and hospital length of stay were no different in SDD (n = 18) and control (n = 18) groups. A total of 14 Gram-negative infections (intraabdominal abscess 7, septicemia 5, pneumonia 1, urinary tract 1) developed in the 36 patients studied. Mortality was not significantly different in the two groups. However, there were significantly fewer patients with Gram-negative infections in the SDD group: 3/18 patients (11%) vs. 11/18 patients (50%) in the control group, P < 0.001. There was also significant reduction in aerobic Gram-negative flora in the stool and pharynx in patients receiving SDD. Gram-positive and anaerobic organisms were unaffected. We conclude that short-term postoperative SDD significantly reduces Gram-negative infections in pediatric OLT patients.

    Cholestatic liver diseases include a group of diverse disorders with different epidemiology, pathophysiology, clinical course, and prognosis. Despite significant advances in the clinical care of patients with cholestatic liver diseases, liver transplant (LT) remains the only definitive therapy for end-stage liver disease, regardless of the underlying cause. As per the United Network for Organ Sharing database, the rate of cadaveric LT for cholestatic liver disease was 18% in 1991, 10% in 2000, and 7.8% in 2008. This review summarizes the available evidence on various common and rare cholestatic liver diseases, disease-specific issues, and pertinent aspects of LT. Copyright © 2013 Elsevier Inc.

    Full Text Available Russian Scientist Centre for Radiology and Surgical Technology has sufficient experience of orthotopic liver transplantation (100 OLT, which allowed comparing the outcomes of the terminal stages of liver disease in the two most numerous groups of patients: viral cirrhosis (VH and autoimmune liver diseases (AILD. Despite the fact that patients with VH indicator of urgency performing OLT (MELD lower, rate of deaths on the waiting list higher than AILD, due to more favorable course of immune disease. After OLT significant differences during the early and last posttransplant periods were not found, although the recurrences of viral hepatitis are recorded much more frequently than AILD. One-year and a three-year survival rates were comparable. To prevent reinfection of the hepatitis B successfully used nucleoside analogues (telbivudine, which allowed minimizing recurrence of the disease. Prevention and treatment of hepatitis C after the OLT is a relevant problem, despite the low efficiency of antiviral therapy. Relapses AILD not represent a real threat to the life of the patients, because the modification of immunosuppressive therapy can limit the progression of the disease.

    Titration of volatile anesthetics to anesthetic effect monitoring using the bispectral index (BIS) has been shown to decrease anesthetic requirements and facilitate recovery from anesthesia unrelated to liver transplantation (OLT). To determine whether availability of such monitoring influences its utilization pattern and affect anesthetic care and outcomes in OLT, we conducted a retrospective analysis in recipients with and without such monitoring. We evaluated annual BIS utilization over a period of 7 years, and compared 41 BIS-monitored patients to 42 controls. All received an isoflurane/air/oxygen and opioid-based anesthetic with planned postoperative ventilation. Data collection included age, body mass index (BMI), gender, Model for End-stage Liver Disease (MELD) score, and time to extubation (TtE). Mean preanhepatic, anhepatic, and postanhepatic end-tidal isoflurane concentrations were compared, as well as BIS values for each phase of OLT using the Kruskal-Wallis and Wilcoxon signed-rank tests, respectively. The use of anesthetic effect monitoring when available increased steadily from 15% of cases in the first year to almost 93% by year 7. There was no significant difference in age, gender, BMI, MELD, or TtE between groups. The BIS group received less inhalational anesthetic during each phase of OLT compared to the control group. However, this difference was statistically significant only during the anhepatic phase (P = .026), and was clinically not impressive. Within the BIS group, the mean BIS value was 38.74 ± 5.25 (mean ± standard deviation), and there was no difference for the BIS value between different transplant phases. Availability of anesthetic effect monitoring as an optional monitoring tool during OLT results in its increasing utilization by anesthesia care teams over time. However, unless integrated into an intraoperative algorithm and an early extubation protocol for fast tracking of OLT recipients, this utilization does not appear to provide

  5. Contradictory Immune Response in Post Liver Transplantation Hepatitis B and C

    2014-01-01

    Full Text Available Hepatitis B and C often progress to decompensated liver cirrhosis requiring orthotopic liver transplantation (OLT. After OLT, hepatitis B recurrence is clinically controlled with a combination of hepatitis B immunoglobulin (HBIG and nucleos(tide analogues. Another approach is to induce self-producing anti-hepatitis B virus (HBV antibodies using a HBV envelope antigen vaccine. Patients who had not been HBV carriers such as acutely infected liver failure or who received liver from HBV self-limited donor are good candidate. For chronic HBV carrier patients, a successful response can only be achieved in selected patients such as those treated with experimentally reduced immunosuppression protocols or received an anti-HBV adaptive memory carrying donor liver. Hepatitis C virus (HCV reinfects transplanted livers at a rate of >90%. HCV reinfected patients show different severities of hepatitis, from mild and slowly progressing to severe and rapidly progressing, possibly resulting from different adaptive immune responses. More than half the patients require interferon treatment, although the success rate is low and carries risks for leukocytopenia and rejection. Managing the immune response has an important role in controlling recurrent hepatitis C. This study aimed to review the adaptive immune response in post-OLT hepatitis B and C.

    Full Text Available Abstract Background Cerebrovascular complications are severe events following orthotopic liver transplantation (OLT. This study aimed to observe the clinical and neuroimaging features and possible risk factors of in-hospital cerebrovascular complications in the patients who underwent OLT. Patients and methods We retrospectively reviewed 337 consecutive patients who underwent 358 OLTs. Cerebrovascular complications were determined by clinical and neuroimaging manifestations, and the possible risk factors were analyzed in the patients with intracranial hemorrhage. Results Ten of 337 (3.0% patients developed in-hospital cerebrovascular complications (8 cases experienced intracranial hemorrhage and 2 cases had cerebral infarction, and 6 of them died. The clinical presentations were similar to common stroke, but with rapid deterioration at early stage. The hematomas on brain CT scan were massive, irregular, multifocal and diffuse, and most of them were located at brain lobes and might enlarge or rebleed. Infarcts presented lacunar and multifocal lesions in basal gangliar but with possible hemorrhagic transformation. The patients with intracranial hemorrhage had older age and a more frequency of systemic infection than non-intracranial hemorrhage patients. (P = 0.011 and 0.029, respectively. Conclusion Posttransplant cerebrovascular complications have severe impact on outcome of the patients who received OLT. Older age and systemic infection may be the possible risk factors of in-hospital intracranial hemorrhage following OLT.

    Full Text Available Aim. Comparative evaluation of two biochemical markers of bone resorption and hormonal regulation of bone metabolism in liver recipients. Methods and results. Bоne densitometry of L2–L4 and neck of femur, serum level of some hormones (PTH, vitamin D3, estradiol, testosterone regulating osteoclastogenesis as well as com- parative analyses of two bone resorption markers β-crosslaps and tartrate-resistant acid phosphatase type 5b (TRAP-5b were fulfilled in patients after orthotopic liver transplantation (OLT. In 1 month after OLT bone density reduction of L2–L4 and neck of femur; decrease of vitamin D3, estradiol in women, testosterone in men and increase levels of bone resorption markers were observed. In 1 and 2 years after OLT the rise of bone density, increased levels of PTH, estradiol, testosterone and decreased β-crosslaps levels were revealed, while vitamin D3 and TRAP-5b levels remained stable. Conclusion. TRAP-5b was found to be a more speciffic marker of bone resorption, independent from collagen metabolism in liver. Osteoporosis defined in long-term period after OLT was associated with higher TRAP-5b and revialed in women with low estradiol level.

    Purpose: To observe bone loss and bone metabolism status in 5-year survivors after orthotopic liver transplantation (OLT). Methods: Measurement of bone mineral density (BMD) of the lumbar spine (L2∼L4) and femoral neck using dual energy X-ray absorptiometry (DEXA) and analysis of biochemical markers of bone turnover, such as ostecalcin (OSC), bone alkaline phosphatase (BAP), carboxy-terminal propeptide of type I procollagen (PICP), carboxy-terminal cross-linked telo-peptide of type I collagen (ICTP), PTH and 25-hydroxy-vitamin D (25-OH-D). These markers were measured in 31 5-year survivors after OLT, 34 patients with chronic liver failure (CLF) before OLT and 38 normal subjects. Results: Age-matched Z-score of BMD (Z-score) at L2∼L4 was significantly higher in 5-year survivors than that in patients with CLF before OLT. Incidence of osteoporosis (Z-score<-2.0) in 5-year survivors was significantly lower than that in patients with CLF before OLT. Although serum concentrations of bone formation and bone resorption markers in 5-year survivors were high than those of normal subjects, as compared to patients with CLF before OLT, serum OSC was increased, serum ICTP and BAP were reduced, serum PICP was unchanged. Serum PTH and 25-OH-D level was normal. Conclusions: In 5-year survivors following liver transplantation there was a reduction in bone loss and incidence of osteoporosis and an improvement of bone metabolism

    Objective: To evaluate the safety and efficacy of the endovascular interventional techniques for the management of emergent hepatic artery thrombosis (HAT) after orthotopic liver transplantation (OLT). Methods: Ten patients (8 men and 2 women with mean age of 47 years) diagnosed with HAT after OLT were treated with interventional procedures. All patients presented with elevation of liver enzymes and bilirubin levels. The diagnosis of the HAT was suggested by doppler ultrasonography and confirmed by angiography at 16 hours to 10 days (mean, 4.5 days) after OLT. Interventional techniques consisted of indwelling transcatheter hepatic arterial thrombolysis with a low dose of urokinase monitored under ultrasonography every 6-12 hours and stent placement in the stenotic segment of the hepatic artery was undertaken. Systemic intravenous low dose of heparin was given contemporaneously. Results: Complete occlusion of the proper HA was achieved in 10 patients. Hepatic arterial flow was re-established in 8 of the 10 patients (80%) at 12 hours to 9 days (mean, 4.8 days) after the intra-arterial thrombolysis, with significant improvement of liver function. Hepatic artery stenosis at the anastomosis was found in the 8 patients, and a stent placement in the stenotic segment was performed successfully in 7 patients with degree of stenosis over 90%.Intra-arterial thrombolysis was failed in 2 cases. Intraperitoneal hemorrhage from the anastomosis occurred in 1 patient at 12 hours after the treatment, and was emergently taken for the graft revision with reanastomosis. One patient with complete occlusion of the hepatic artery at 7 days after the treatment, but having collateral flow of the liver for maintaining liver function and thus sparing further intervention. 8 patients with successful hepatic arterial recanalization carried along a good clinical course with normal graft function at a median 12 months (range, 4 to 20 months), and patent hepatic arterial flow was identified by

    Liver transplantation is the only effective and definitive treatment for patients with end-stage liver disease. The shortage of cadaveric livers has lead to the increasing use of split-liver transplantation and living-donor liver transplantation, but the expansion of the donor pool has increased the risk for postoperative vascular and biliary complications. Early recognition of the imaging appearances of the various postoperative complications of liver transplantation is crucial for both graft and patient survival. This review describes the imaging findings of normal and abnormal transplanted liver parenchyma and of vascular and biliary post-transplantation complications. (orig.)

    Full Text Available Many of the nontransplant physicians who manage hepatic patients (internists and hepatologists keep asking about liver transplantation. The purpose of this article is to highlight important topics a nontransplant colleague may require in his practice. There are many topics in this respect; however, three most important topics need to be highlighted; those are; the time of referral to transplantation, the indications and contraindications and the metabolic issues regarding a transplanted patient. Still, there are no clear guidelines for the management of many of the metabolic issues regarding liver transplanted patients. And this why, collaborative efforts of transplant and nontransplant physicians are needed to conduct multicenter, long term randomized controlled trials and proper follow up programs.

    2017-10-01

    Full Text Available Protein-energy malnourishment is commonly encountered in patients with end-stage liver disease who undergo liver transplantation. Malnutrition may further increase morbidity, mortality and costs in the post-transplantation setting. The importance of carefully assessing the nutritional status during the work-up of patients who are candidates for liver replacement is widely recognized. The metabolic abnormalities induced by liver failure render the conventional assessment of nutritional status to be challenging. Preoperative loss of skeletal muscle mass, namely, sarcopenia, has a significant detrimental impact on post-transplant outcomes. It is essential to provide sufficient nutritional support during all phases of liver transplantation. Oral nutrition is preferred, but tube enteral nutrition may be required to provide the needed energy intake. Herein, the latest currently employed perioperative nutritional interventions in liver transplant recipients are thoroughly illustrated including synbiotics, micronutrients, branched-chain amino acid supplementation, immunonutrition formulas, fluid and electrolyte balance, the offering of nocturnal meals, dietary counselling, exercise and rehabilitation.

    Xingmu Liu

    Full Text Available Sleeve anastomosis is the most common technique used to rearterialize orthotopic liver transplants (OLT. However, this technique has a number of disadvantages, including difficulty of performance of the technique visually unaided. We herein describe a novel rearterialized OLT model in the rat.Forty-six male Sprague Dawley rats (300-400 g were used as donors and recipients. Based on Kamada's cuff technique, the new model involved performing a modified "sleeve" anastomosis between the celiac trunk of the donor and common hepatic artery of the recipient to reconstruct blood flow to the hepatic artery. An additional ten male Sprague Dawley rats underwent liver transplantation without artery reconstruction. Liver grafts were retrieved from the two groups and histological examination was performed following surgery.Total mean operating times were ~42 minutes for the donor liver extraction and 57 minutes for the recipient transplantation. Graft preparation took an additional 15 minutes and the time to fix the arterial bracket was ~3 minutes. During transplantation, the anhepatic phase lasted 18 ± 2.5 min and the artery reconstruction only required ~3 minutes. The patency rate was 94.44% and the 4-week survival rate was 90%. Histology indicated obvious fibrosis in the liver grafts without artery reconstruction, while normal histology was observed in the arterialized graft.This new method allows for the surgical procedure to be performed visually unaided with good survival and patency rates and represents an alternative model investigating OLT in rats.

    OBJECTIVE: Polycystic liver disease (PLD) is a rare, hereditary, benign disorder. Hepatic failure is uncommon and symptoms are caused by mass effects leading to abdominal distension and pain. Liver transplantation (LTX) offers fully curative treatment, but there is still some controversy about...... whether it is a relevant modality considering the absence of liver failure, relative organ shortage, perioperative risks and lifelong immunosuppression. The purpose of this study was to review our experience of LTX for PLD and to compare the survival with the overall survival of patients who underwent LTX...... from 1992 to 2005. MATERIAL AND METHODS: A retrospective study of the journals of 440 patients, who underwent 506 LTXs between 1992 and 2005, showed that 14 patients underwent LTX for PLD. All patients had normal liver function. Three were receiving haemodialysis and thus underwent combined liver...

    Liver transplantation remains an effective treatment for those with end-stage disease and with intractable liver-related symptoms.The shortage of organs for transplantation has resulted in the need for rationing.A variety of approaches to selection and allocation have been developed and vary from country to country.The shortage of donors has meant that new approaches have to be adopted to make maximal use of the available organs;these include splitting grafts,use of extended criteria livers,livers from nonheart-beating donors and from living donors.Post transplantation, most patients will need life-long immunosuppression,although a small proportion can have immunosuppression successfully withdrawn.Newer immunosuppressive drugs and different strategies may allow a more targeted approach with a reduction in sideeffects and so improve the patient and graft survival.For autoimmune diseases, transplantation is associated with significant improvement in the quality and length of life.Disease may recur after transplantation and may affect patient and graft survival.

  20. Role of MELD score and serum creatinine as prognostic tools for the development of acute kidney injury after liver transplantation.

    Directory of Open Access Journals (Sweden)

    Thiago Gomes Romano

    Full Text Available BACKGROUND: The role of the Model for End-Stage Liver Disease (MELD score in predicting complications, such as Acute Kidney Injury (AKI, after orthotopic liver transplantation (OLT has yet to be evaluated and serum creatinine may be too heavily weighted in the existing MELD formula, since it has many pitfalls in cirrhotic patients. METHODS: Retrospective data of the perioperative period from consecutive adult OLTs performed from January to December 2009 were recorded. Univariate and multivariate analysis were performed to analyze the risk factors for AKI and mortality after OLT. RESULTS: There were 114 OLTs performed in the study period, 22 (19,2% were submitted to dialysis prior OLT and were excluded from the analysis for AKI. The median age was 52 years and 66% were male. Median creatinine value was 0.85mg/dL and MELD was 19. Fifty-two of the 92 patients (56,5% developed AKI in the first 72 hours after OLT. The only independent risk factor for AKI was calculated MELD and when the components of the MELD score were analyzed, INR had a much stronger impact in predicting AKI then serum creatinine. Overall mortality rate was 32,5% and anesthesia duration was the only variable associated with higher mortality rate. CONCLUSIONS: Although MELD score seems to have a good performance in predicting AKI after OLT, serum creatinine had no impact on its prediction despite its importance on MELD calculation. Modifying the MELD score, which could include novel AKI biomarkers, may improve its prognostic accuracy and provide a better tool for public health planning.

  1. Depression and Liver Transplant Survival.

    Science.gov (United States)

    Meller, William; Welle, Nicole; Sutley, Kristen; Thurber, Steven

    Patients who underwent liver transplantation and experienced clinical depression have heretofore evinced lower survival rates when compared to nondepressed counterparts. To investigate the hypothesis that transplant patients who seek and obtain medical treatment for depression would circumvent the prior reduced survival findings. A total of 765 patients with liver transplants were scrutinized for complications following transplantation. Further, 104 patients experienced posttransplant depression as manifested by diagnosis and treatment by medical personnel. Survival analyses were conducted comparing hazard and survival curves for these selected individuals and the remainder of transplant patients. Contrary to prior data and consistent with the aforementioned hypothesis, median survival durations, survival curves, and hazard functions (controlling for age and prolonged posttransplant survival for the depressed patients were better. The improved survival for the depressed patients may simply be related to an amelioration of depressed symptoms via antidepressant medications. However, this interpretation would only be congruent with reduced hazard, not elevated survival, beyond the norm (median) for other transplant participants. Assuming the reliability and generalization of our findings, perhaps a reasonable and compelling interpretation is that combined with the effectiveness of antidepressant medications, the seeking and receiving treatment for depression is a type of proxy measure of a more global pattern of adherence to recommended posttransplant medical regimens.

    Full Text Available Introduction. Almost all pediatric orthotopic liver transplant (OLT recipients require mechanical ventilation in the early postoperative period. Prolonged postoperative mechanical ventilation (PPMV may be a marker of severe disease and may be associated with morbidity and mortality. We determined the incidence and risk factors for PPMV in children who underwent OLT. Methods. This was a retrospective analysis of data collected on 128 pediatric OLT recipients. PPMV was defined as postoperative ventilation ≥ 4 days. Perioperative characteristics were compared between cases and control groups. Multivariable logistic regression analysis was used to calculate odds ratios for PPMV after controlling for relevant cofactors. Results. An estimated 25% (95% CI, 17.4%–32.6% required PPMV. The overall incidence of PPMV varied significantly by age group with the highest incidence among infants. PPMV was associated with higher postoperative mortality (p=0.004 and longer intensive care unit (p<0.001 and hospital length of stay (p<0.001. Multivariable analysis identified young patient age, preoperative hypocalcemia, and increasing duration of surgery as independent predictors of PPMV following OLT. Conclusion. The incidence of PPMV is high and it was associated with prolonged ICU and hospital LOS and higher posttransplant mortality. Surgery duration appears to be the only modifiable predictor of PPMV.

    Orthotopic liver transplantations (OLT) have been associated with significant blood loss and hemodilution, necessitating significant homologous blood component replacement. Increasing administration of homologous blood products has been found to be inversely related to patient and graft survival. Various methods to reduce the amount of blood products patients receive during OLT, such as antifibrinolytic therapy, thromboelastography-guided transfusion, phlebotomy, reduced central venous pressures intraoperatively, and the use of the veno-venous bypass (VVB) circuit, have been explored.The asanguineous priming volume of the VVB circuit increases the likelihood of the patient receiving homologous blood products due to hemodilution. It was reasoned that autologous priming of the VVB circuit in OLT surgery was a plausible adjunctive blood conservation technique given its application to the extracorporeal circuit during cardiac surgery. We describe our technique of modifying the VVB circuit for autologous priming. This technique adds minimal risk and a small amount of cost to the procedure, requires slightly more communication among members of the surgical team, and with proper sequencing, adds no additional length to the surgical procedure. It is recommended that this technique be considered for addition to the arsenal of blood conservation techniques when VVB is used during OLT.

    Fracturing after liver transplantation (OLT) occurs due to the combination of preexisting low bone mineral density (BMD) and early posttransplant bone loss, the risk factors for which are poorly defined. The prevalence and predictive factors for hepatic osteopenia and osteoporosis, posttransplant bone loss, and subsequent bone gain were studied by the long-term posttransplant follow-up of 360 consecutive adult patients with end-stage primary biliary cirrhosis (PBC) and primary sclerosing cholangitis (PSC). Only 20% of patients with advanced PBC or PSC have normal bone mass. Risk factors for low spinal BMD are low body mass index, older age, postmenopausal status, muscle wasting, high alkaline phosphatase and low serum albumin. A high rate of spinal bone loss occurred in the first 4 posttransplant months (annual rate of 16%) especially in those with younger age, PSC, higher pretransplant bone density, no inflammatory bowel disease, shorter duration of liver disease, current smoking, and ongoing cholestasis at 4 months. Factors favoring spinal bone gain from 4 to 24 months after transplantation were lower baseline and/or 4-month bone density, premenopausal status, lower cumulative glucocorticoids, no ongoing cholestasis, and higher levels of vitamin D and parathyroid hormone. Bone mass therefore improves most in patients with lowest pretransplant BMD who undergo successful transplantation with normal hepatic function and improved gonadal and nutritional status. Patients transplanted most recently have improved bone mass before OLT, and although bone loss still occurs early after OLT, these patients also have a greater recovery in BMD over the years following OLT.

    Full Text Available Patients after orthopic liver transplantation (OLT are at risk of developing graft dysfunction. Sphingolipids (SL’s have been identified to play a pivotal role in the regulation of hepatocellular apoptosis, inflammation and immunity. We aimed to investigate the serum SL profile in a prospective real-world cohort of post-OLT patients. From October 2015 until July 2016, 149 well-characterized post-OLT patients were analyzed. SL’s were assessed in serum probes via Liquid Chromatography/Tandem Mass Spectrometry. Twenty-nine (20% patients had a biopsy proven graft rejection with decreased C20-ceramide (Cer (p = 0.042, C18-dihydroceramide (DHC (p = 0.022 and C24DHC (p = 0.060 levels. Furthermore, C18DHC (p = 0.044 and C24DHC (p = 0.011 were significantly down-regulated in patients with ischemic type biliary lesions (ITBL; n = 15; 10%. One-hundred and thirty-three patients (89% have so far received tacrolimus as the main immunosuppressive agent with observed elevations of C14Cer (p = 0.052, C18Cer (p = 0.049 and C18:1Cer (p = 0.024. Hepatocellular carcinoma (HCC pre-OLT was associated with increases in C24:1Cer (p = 0.024 and C24:1DHC (p = 0.024. In this large prospective cross-sectional study of patients, post-OLT serum levels of (very-long chain (dihydro-ceramides associate with graft rejection, ITBL, tacrolimus intake and HCC pre-OLT. Hence, serum SL’s may be indicative of graft complications. Further research is necessary to identify their diverse mechanistic role in regulating immunity and inflammation in patients post-OLT.

    The purpose of this study was to evaluate the accuracy of MDCT for preoperative assessment of hepatic vascular anatomy and the identification of liver-transplantation (OLT) patients at risk of developing subsequent splenic artery steal syndrome (SASS). A total of 145 patients with liver cirrhosis who had undergone OLT and had pre-operative three-phase MDCT (4- to 64-rows) within 100 days before OLT were enrolled retrospectively. MDCT and 3Ds were reviewed by two independent blinded observers (O1/O2). Pre-operative imaging findings were correlated with intra-operative results; findings indicative for SASS were correlated with clinical data and DSA. Among all 145 patients, 16 patients (11%) showed accessory hepatic arteries (accuracy O1/O2, 97%; with 3Ds, 100%); 32 (22%) patients had replaced hepatic arteries (accuracy O1, 97%; O2, 95%; with 3Ds, 100%; κ=0.87 and 0.89, P<0.001). Among 119 patients, 12 patients developed SASS after OLT. The logistic regression model revealed the spleen volume (P=0.0105) as a predictive factor of SASS. With spleen volumes ≥829 ml, an accuracy of 75% for prediction of SASS was obtained. MDCT with three-dimensional post-processing (3Ds) was highly accurate for pre-operative hepatic vessel evaluation in patients before OLT. In addition, spleen volume was a predictive factor for developing SASS after OLT. (orig.)

    The aim of this paper is to review the current status of liver transplantation (LT) for Wilson disease (WD), focusing on indications and controversies, especially in patients with neuropsychiatric disease, and on identification of acute liver failure (ALF) cases related to WD. LT remains the treatment of choice for patients with ALF, as initial presentation of WD or when anti-copper agents are stopped, and for patients with chronic liver disease progressed to cirrhosis, unresponsive to chelating medications or not timely treated with copper chelating agents. The indication for LT in WD remains highly debated in patients with progressive neurological deterioration and failure to improve with appropriate medical treatment. In case of Wilsonian ALF, early identification is key as mortality is 100% without emergency LT. As many of the copper metabolism parameters are believed to be less reliable in ALF, simple biochemical tests have been proposed for diagnosis of acute WD with good sensitivity and specificity. LT corrects copper metabolism and complications resulting from WD with excellent 1 and 5 year survival. Living related liver transplantation represents an alternative to deceased donor LT with excellent long-term survival, without disease recurrence. Future options may include hepatocyte transplantation and gene therapy. Although both of these have shown promising results in animal models of WD, prospective human studies are much needed to demonstrate their long-term beneficial effects and their potential to replace the need for medical therapy and LT in patients with WD.

    Hepatitis C virus (HCV)-related liver disease represents the leading indication for liver transplantation (LT) in the USA and Europe and HCV recurrence is universal in recipients who are viremic at LT. Until a few years ago, pegylated-interferon in association with ribavirin was the only therapeutic strategy, usable only in compensated cirrhotic patients, in order to prevent post-LT viral recurrence. The recent advent of direct-acting antiviral agents (DAAs) has dramatically increased the chances of curative treatment for the transplant population and the debate about which should be the best time for treating the infection is still open: whether to pursue HCV eradication 1) before LT, in order to improve liver function, delist some patients and prevent graft infection; or 2) as early as possible after LT, rather than 3) waiting for hepatitis C recurrence before starting treatment. In addition, in the DAA era, the use of HCV-positive donors may represent a potential approach to safely expanding the donor pool. As more HCV patients achieve cure with DAA regimens, the LT trend for HCV in the future would be expected to mimic the trend observed for hepatitis B virus in the past decade and in the United States, during the DAA-period 2014-2015, the rate of LT wait-listing for HCV complicated by decompensated cirrhosis has already decreased by 32%. This review summarizes the published data and emphasizes DAA treatment applicability to patients with decompensated cirrhosis and to liver transplant recipients.

    Background Although liver transplantation has become a standard therapy for end-stage liver diseases, the experience of pediatric liver transplantation is limited in China. In this article we report our experience in pediatric liver transplantation, and summarize its characters in their indications, surgical techniques, and postoperative managements. Methods Thirty-one children (≤18 years old) underwent liver transplantation in our centers. The mean age at transplantation was 12.4 years old (ranged from 5 months to 18 years) with 7 children being less than 4 years of age at transplantation. The most common diagnosis of patients who underwent liver transplantation were biliary atresia, Wilson's disease, primary biliary cirrhosis, glycogen storage disease, hepatoblastoma, urea cycle defects, fulminant hepatic failure, etc. The surgical procedures included 12 standard (without venovenous bypass), 6 pigyback, 6 reduced-size, 3 split, 3 living donor liver transplantation, and 1 Domino liver transplantation. The triple-drug (FK506, steroid, and mycophenolate mofetil) immunosuppressive regimen was used in most of patients. Patients were followed up for a mean of 21.8 months. Results Five of the 31 patients died during perioperative time; mortality rate was 16.1%. The reasons of death were infections, primary non-function, heart failure, and hypovolemic shock. Postoperative complications in 10 patients included biliary leakage, acute rejection, abdominal infection, hepatitis B virus (HBV) or hepatitis C virus (HCV) infection, and pulmonary infection. Overall patient cumulative survival rate at 1-, 3-, and 5-year was 78.1%, 62.6%, 62.6%, respectively.Conclusions The most common indications of pediatric liver transplantation were congenital end-stage liver diseases. According to patients' age and body weight, standard, piggyback, reduced-size, split, or living donor liver transplantation should be performed. Pediatric liver transplantation especially requires higher

    Full Text Available Background. Whether routine antifungal prophylaxis decreases posttransplantation fungal infections in patients receiving orthotopic liver transplantation (OLT remains unclear. This study aimed to determine the effectiveness of antifungal prophylaxis for patients receiving OLT. Patients and Methods. This is a retrospective analysis of a database at Chang Gung Memorial Hospital. We have been administering routine antibiotic and prophylactic antifungal regimens to recipients with high model for end-stage liver disease scores (>20 since 2009. After propensity score matching, 402 patients were enrolled. We conducted a multistate model to analyze the cumulative hazards, probability of fungal infections, and risk factors. Results. The cumulative hazards and transition probability of “transplantation to fungal infection” were lower in the prophylaxis group. The incidence rate of fungal infection after OLT decreased from 18.9% to 11.4% (p=0.052; overall mortality improved from 40.8% to 23.4% (p<0.001. In the “transplantation to fungal infection” transition, prophylaxis was significantly associated with reduced hazards for fungal infection (hazard ratio: 0.57, 95% confidence interval: 0.34–0.96, p=0.033. Massive ascites, cadaver transplantation, and older age were significantly associated with higher risks for mortality. Conclusion. Prophylactic antifungal regimens in high-risk recipients might decrease the incidence of posttransplant fungal infections.

    Biliary complications (BC) occur in up to 39.5% of patients after orthotopic liver transplantation (OLT), being an important source of post-transplant morbidity. The aim is to evaluate the incidence of BC after OLT, associated risk factors and outcome after endoscopic treatment. A retrospective case series between June 2005 and December 2008, including 195 patients that underwent 216 OLT from deceased donors. Thirty-one patients (14.3%) presented at least 1 BC, anastomotic stricture being the most frequent (83.8%). Non-anastomotic stricture was present in 1 (3.2%) and anastomotic fistula in 1. One patient presented anastomotic disconnection at ERCP. BC occurred 94.6 (7-487) days after OLT. Twenty-seven patients underwent endoscopic treatment, on average 2.6 ERCPs were performed per patient. Global endoscopic treatment success rate was 77.3%; being 73.7% for stenosis and 100% (3/3) for anastomotic fistula with stenosis. Recurrence of biliary stricture was observed in 3 patients, all referred to endoscopic re-treatment. ERCP complications: 2 (2.8%) stent migrations, 1 (1.4%) early stent occlusion, 1 (1.4%) respiratory distress and 1(1.4%) severe acute pancreatitis and death. There was no correlation between studied risk factors and BC's occurrence. ERCP was effective for the treatment of BC after OLT. Studied risk factors had no correlation with BC.

    The aim of this study was to determine the accuracy of contrast-enhanced biphasic spiral CT as a screening tool in the preoperative evaluation of orthotopic liver transplant (OLT) patients. Spiral-CT examinations were performed before liver transplantation in 53 patients. Scans were retrospectively reviewed and compared with pathologic findings in fresh-sectioned livers. When findings between spiral CT and pathology were discordant, formalized livers were reexamined with lesion-by lesion evaluation. Fresh pathologic evaluation revealed 23 liver lesions (16 HCC, 7 macro-regenerative nodules). Malignancy was identified in 13 of 53 patients (24.5%). Pre-transplantation spiral CT depicted 27 liver lesions (23 HCC, 4 macro-regenerative nodules). Malignancy was suspected in 14 patients (26.4%). In 10 of 53 (18.9%), spiral CT and pathologic evaluation were discordant. Subsequent retrospective pathologic evaluation showed malignancy in 4 additional patients. Spiral CT compared with the retrospective pathologic findings revealed 36 real-negative, 14 real-positive, 0 false-positive, and 3 false-negative patients with malignancy. Sensitivity and specificity of spiral CT in detection of malignancy was 82 and 100%, respectively. Contrast-enhanced biphasic spiral CT is an accurate technique in the evaluation of patients preceding OLT. Routine fresh-sectioned liver pathologic findings are not as sensitive as previously estimated. (orig.)

    With the advances in technical skills,management of postoperative complications and improvements in immunosuppressive drugs,liver transplantation is the standard treatment for many patients with chronic liver disease.Today,shortage of donor organs seems to be the major limiting factor for the application of liver transplantation.This review focuses on five issues that are challenging to clinical practice of liver transplantation and relevant to gastroenterologists.These include living donor liver transplantation,recurrent viral hepatitis,non-heart-beating donors,hepatocellular carcinoma,and ABO incompatible livertransplantation.Living donor and non-heart beating donor transplantations were initiated as a solution to increase the donor organ pool and it is expected that there will be an increase in the number of these donors.Recurrent hepatitis C and hepatocellular carcinoma following liver transplantation are among major problems and ongoing research in these diseases may lead to better outcomes in these recipients.

    Full Text Available Abstract Background Orthotopic liver transplantation (OLT is one of the most effective treatments for patients with hepatocellular carcinoma (HCC within the Milan criteria. However, for patients beyond these criteria, the recurrence rate is higher and the prognosis is worse. Sorafenib is the only drug showing survival benefits in advanced HCC patients; however, its role in patients beyond the Milan criteria after OLT remains unclear and requires further investigation. Methods As a case-control study, we retrospectively analyzed 17 Chinese patients beyond Milan criteria undergoing OLT for HCC. These patients were stratified into adjuvant (n = 5, palliative (n = 6, and control groups (n = 6. Results Nine of 11 patients who received sorafenib after OLT needed dose reduction due to more than grade 2 side effects. The disease-free survival rates for patients with or without adjuvant sorafenib were 100% versus 37.5% (p = 0.034 at 6 months, 66.7% versus 9.4% (p = 0.026 at 12 months, and 66.7% versus 0.0% (p = 0.011 at 18 months, respectively. The overall survival rates for patients in palliative and control groups were 66.7% versus 40.0% (p = 0.248 at 6 months, 66.7% versus 40.0% (p = 0.248 at 12 months, and 50.0% versus 20.0% (p = 0.17 at 18 months, respectively. Patients in the adjuvant group had better overall survival rates than those in the palliative and control groups (p = 0.031 at 24-month follow-up. Conclusions Adjuvant sorafenib could possibly extend both disease-free and overall survival for HCC patients beyond Milan criteria after OLT.

    The urea cycle is the final pathway for nitrogen metabolism. Urea cycle disorders (UCDs) include a variety of genetic defects, which lead to inefficient urea synthesis. Elevated blood ammonium level is usually dominant in the clinical pattern and the primary manifestations affect the central nervous system. Herein, we report the case of a 17-year-old girl who was diagnosed with UCD at the age of 3. Despite a controlled diet, she was hospitalized several times for acute attacks with recurrent life risk. She came to our attention for a hyperammonemic episode. We proposed an orthotopic liver transplant (OLT) as a treatment; the patient and her family were in complete agreement. On February 28, 2007, she successfully received a transplant. Following the surgery, she has remained well, and she is currently leading a normal life. Usually for UCDs diet plays the primary therapeutic role, while OLT is often considered as a last resort. Our case report and the recent literature data on the quality of life and prognosis of traditionally treated patients vs OLT patients, support OLT as a primary intervention to prevent life-threatening acute episodes and chronic mental impairment.

    Objective: To investigate the diagnosis and interventional therapeutic technology for the obstruction of hepatic vein (HV) or inferior vena cava (IVC) after liver transplantation. Methods: In the 831 patients who received orthotopic liver transplantation (OLT) and 26 patients who received living donor liver transplantation (LDLT), 11 cases were confirmed with HV or IVC obstruction by venography and received interventional treatment from 2 to 111 days after liver transplantation. Of the 11 patients, five had the obstruction of HV anastomosis, five had the obstruction of IVC anastomosis, and one had the obstruction of HV and IVC anastomosis. In the eleven patients, five patients underwent OLT, four patients underwent LDLT, and two pediatric patients underwent reduced-size OLT. Before interventional treatment, 9 patients function tests, clinical sympatom, and monitoring of HV or IVC flow. Pressure gradients before and after therapeutic technology of 11 cases were retrospectively analyzed. Results: In all 11 patients, CT or MRI could clearly show congested areas of the liver, and the location and degree of HV or IVC obstruction. Of the 11 patients, four with HV obstruction and five with IVC obstruction were treated with stent placement, one with HV obstruction was treated with percutaneous transluminal angioplasty (PTA), one with HV and IVC obstruction was treated with HV PTA and IVC stent placement. Interventional technical success was achieved in all patients. The venous pressure gradient across obstruction was significantly reduced from (16.5 ± 4.1) mm Hg (1 mm Hg =0.133 kPa) before the procedure to (2.9 ± 1.7) mm Hg after the procedure (t=11.5, P<0.01). Clinical improvement was noted in 10 patients except one pediatric patient who died of multiple-organs failure at the 9 th day after the treatment. During the follow-up period of 9 to 672 days, two patients with PTA treatment had recurrent HV stenosis within one month after treatment, no patient with stent

    Orthotopic liver transplantation (OLT) indication for hepatocellular carcinoma (HCC) is currently based on the Milan criteria. The University of California, San Francisco (UCSF) recently proposed an expansion of the selection criteria according to tumors characteristics on the explanted liver. This study: 1) assessed the validity of these criteria in an independent large series and 2) tested for the usefulness of these criteria when applied to pre-OLT tumor evaluation. Between 1985 and 1998, 479 patients were listed for liver transplantation (LT) for HCC and 467 were transplanted. According to pre-OLT (imaging at date of listing) or post-OLT (explanted liver) tumor characteristics, patients were retrospectively classified according to both the Milan and UCSF criteria. The 5-yr survival statistics were assessed by the Kaplan-Meier method and compared by the log-rank test. Pre-OLT UCSF criteria were analyzed according to an intention-to-treat principle. Based on the pre-OLT evaluation, 279 patients were Milan+, 44 patients were UCSF+ but Milan- (subgroup of patients that might benefit from the expansion), and 145 patients were UCSF- and Milan-. With a short median waiting time of 4 months, 5-yr survival was 60.1 +/- 3.0%, 45.6 +/- 7.8%, and 34.7 +/- 4.0%, respectively (P OLT evaluation, the UCSF criteria are associated with a 5-yr survival below 50%. Their applicability is therefore limited, despite similar survival rates compared to the Milan criteria, when the explanted liver is taken into account.

    Primary sclerosing cholangitis (PSC) is a chronic, progressive, inflammatory and obstructive disease of the intra- and extra-hepatic bile ducts of unknown etiology. Currently, orthotopic liver transplantation (OLT) is the only definitive treatment for PSC-related end-stage liver disease. However, PSC has been known to recur in the grafted liver. Roux-en-Y hepaticojejunostomy is more commonly performed than choledochocholedochostomy for PSC, although choledochocholedochostomy has been found to be safe and efficacious for PSC if the distal common bile duct is uninvolved at the time of OLT. Our case is unique in that it describes a patient who developed de-novo cholangiocarcinoma in the remnant portion of the native common bile duct six years after OLT with choledochocholedochostomy for PSC-associated end-stage liver disease without having PSC recurrence. In conclusion, our case report indicates that choledochocholedochostomy may not be desirable in PSC due to an increased risk of developing cholangiocarcinoma in the native common bile duct. This risk exists as well with a Roux-en-Y hepaticojejunostomy in the remaining intra-duodenal and intra-pancreatic biliary epithelium, although in theory to a lesser extent. Therefore, the risk of developing cholangiocarcinoma in the recipient common bile duct can only be completely eliminated by performing a Whipple procedure at the time of OLT.

    Purpose: To evaluate the safety and efficacy of the Amplatzer vascular plug (AVP) for embolization of the splenic artery in patients with hepatic hypoperfusion after orthotopic liver transplantation (OLT). Materials and Methods: Thirteen patients (9 men and 4 women) with a mean age of 56 years (range 22–70) who developed splenic artery syndrome after OLT with decreased liver perfusion and clinically relevant impairment of liver function (increased transaminase or serum bilirubin levels, thrombocytopenia, and/or therapy-refractory ascites) were treated by embolization of the proximal third of the splenic artery using the AVP. The plugs ranged in diameter from 6 to 16 mm, and they were introduced through femoral (n = 9), axillary (n = 3), or brachial (n = 1) access using a 5F or 8F guiding catheter. Results: The plugs were successfully placed, and complete occlusion of the splenic artery was achieved in all patients. Placement of two plugs was necessary for complete occlusion in 3 of the 13 patients. Occlusion took on average 10 min (range 4–35). There was no nontarget embolization or plug migration into more distal segments of the splenic artery. All patients showed improved arterial perfusion, including the liver periphery, on postinterventional angiogram. After embolization, liver function parameters (transaminase and bilirubin levels) improved with normalization of concomitant thrombocytopenia and a decrease in ascites volume. Conclusion: Our initial experience in a small patient population with SAS suggests that the AVP enables precise embolization of the proximal splenic artery, thus providing safe and effective treatment for poor liver perfusion after OLT due to SAS.

    Most liver transplant recipients receive either cyclosporin or tacrolimus to prevent rejection. Both drugs inhibit calcineurin phosphatase which is thought to be the mechanism of their anti-rejection effect and principle toxicities. The drugs have different pharmacokinetic profiles and potencies....... Several randomised clinical trials have compared cyclosporin and tacrolimus in liver transplant recipients, but it remains unclear which is superior....

    Living related liver transplantation (LRLT) has been developed in response to the paediatric organ donor shortage. According to the International Living Donor Registry, 521 transplants had been performed in 515 patients between December 8 1988 and January 19 1996 in 30 centres worldwide. The overall actuarial patient and graft survival rates were 82.7 and 80%, respectively. Between June 17 1994 and November 30 1996, the authors performed 11 LRLT at the Chung Gung Memorial Hospital. The living donors consisted of 10 mothers and one father. The mean graft weight was 303 g and the mean graft recipient weight ratio was 2.2%. Donor hepatectomy was performed without vascular inflow occlusion. The intra-operative blood loss ranged from 30 mL to 120 mL with an average of 61 mL, and blood transfusion was not required in all donors both intra-operatively and during the postoperative period. Underlying diseases of the recipients were biliary atresia (n = 10) and glycogen storage disease (n = 1). The mean graft cold ischaemia time was 106 min, the mean second warm ischaemia time was 51 min and the mean interval between portal and arterial reperfusion was 81 min. The initial LRLT results were promising with all donors having been discharged without complication. The recipients experienced a few complications, all of which were manageable with early intervention. All 11 recipients are alive and well. These are encouraging results and the authors hope to expand the use of live donors for liver transplantation to cope with demand.

    The relevance of isolated autoimmunity elevation in orthotopic liver transplantation (OLT) patients is unknown. Our aim was to analyse how serum autoantibodies change in time and to evaluate their clinical relevance in OLT patients. Patients were invited to provide samples to evaluate ANA, AMA, ASMA, and LKM at the time of enrolment ( T 0), after 6 months ( T 6), and after 12 months ( T 12). We included 114 patients in the study (76% males, median age 62.5 years), finding isolated elevation of at least one serum antibody in up to 80% of them. We described fluctuating positive autoantibodies in the one year of observation, with only 45.6% of patients positive for ANA and less than 2% positive for ASMA, at all three times. Isolated elevation of tissue antibodies was not related to gender, age, HCC at transplant, early rejection, cause of transplantation, immunotherapy taken, and age at the time of the study. We did not detect a higher prevalence of positive autoimmunity in patients with signs of liver injury. ANA and ASMA evaluation in patients with liver transplantation and no history of autoimmune disease has no clinical relevance, since it varies in time and is not related to any risk factors or liver injury. Routine autoimmunity evaluation should be avoided.

    Full Text Available Objectives. Endoscopic management of bile leak after orthotopic liver transplant (OLT is widely accepted. Preliminary studies demonstrated encouraging results for covered self-expandable metal stents (CSEMS in complex bile leaks. Methods. Thirty-one patients with post-OLT bile leaks underwent endoscopic temporary placement of CSEMS (3 partially CSEMS , 18 fully CSEMS with fins and 10 fully CSEMS with flare ends between December 2003 and December 2010. Long-term clinical success and safety were evaluated. Results. Median stent indwelling and follow-up were 89 and 1,353 days for PCSEMS, 102 and 849 for FCSEMS with fins and 98 and 203 for FCSEMS with flare ends. Clinical success was achieved in 100%, 77.8%, and 70%, respectively. Postplacement complications: cholangitis (1 and proximal migration (1, both in the FCSEMS with fins. Postremoval complications were biliary strictures requiring drainage: PCSEMS (1, FCSEMS with fins (6 and with flare ends (1. There was no significant differences in the FCSEMS groups regarding clinical success, age, gender, leak location, previous treatment, stent indwelling, and complications. Conclusion. Temporary placement of CSEMS is effective to treat post-OLT biliary leaks. However, a high number of post removal biliary strictures occurred especially in the FCSEMS with fins. CSEMS cannot be recommended in this patient population.

    The aim of this study was to analyse the causes of death after liver transplantation in order to find and to avoid preventable fatal complications if possible. Between September 1988 and September 1993 415 orthotopic liver transplantations in 382 patients were performed at the Rudolf Virchow University Hospital in Berlin. During the same interval 41 (10.7%) of these patients died. Their clinical records were reviewed. The main cause of death was infection (29.3%), followed by recurrent malignancy (21.9%). Less patients died because of hepatitis B-reinfection (14.6%), chronic rejection (7.3%), hemorrhage (7.3%), cardiac failure (7.3%), trauma (4.8%), hypoxia (4.8%) and recurrence of alcoholic liver disease (4.8%). There was a wide spectrum of opportunistic infectious agents with CMV and Pneumocystis carinii being the most important pathogenic organisms. Only one isolated bacterial infection as principle cause of death was found. In all fatal infections the lung was the primary site of infection, 7 patients additionally developed sepsis. Altogether 75 patients (19.6%) with hepatitis B-cirrhosis were transplanted. Six of them (8%) developed a fatal hepatitis B-reinfection. Malignancy was the indication for OLT in 41 patients (10.7%). Six of these patients (14.6%) died because of recurrent tumor. Regarding the whole series, most deaths occurred four to twelve months (58.5%) and only five (12.2%) during the first month after OLT. Recurrence of primary disease is an important factor regarding total mortality. Therefore it is necessary to practise a careful selection of liver transplant recipients. In the future more attention needs to be drawn towards prevention, identification and management of opportunistic infections.

    Mercedes Rubio-Manzanares-Dorado

    Full Text Available Introduction: Post-transplant lymphoproliferative syndrome (PTLD is a rare and potentially life-threatening complication after liver transplantation. The aim of this study was to analyze the clinicopathologic features related to PTLD in a single institution after liver transplantation. Methods: Observational study where we have retrospectively analyzed 851 cases who underwent liver transplantation. Ten cases have developed PTLD. Their clinical-pathological characteristics and the treatment received have been analyzed. Results: PTLD incidence was 1.2% (10/851. The mean time from liver transplantation to PTLD diagnosis was 36 months (range 1.2 to 144 months. PTLD localization was extranodal in all cases, the most frequent location being intestinal. Seven cases showed a monomorphic lymphoma which in all cases was differentiated B cell lymphomas. Fifty per cent of the series were seropositive for Epstein-Barr virus. Five patients were alive at the time of the review. Among these patients, we observed three cases of complete remission and two cases of disease stabilization. The death rate was higher in the first year after diagnosis of PTLD. Conclusion: PTLD is a rare complication after liver transplantation, but it may pose a threat to the life of a liver transplant recipient. It is essential to identify patients at risk, to establish an early diagnosis and treatment that can change the outcome of the disease.

    Full Text Available Background: Severe metabolic acidosis occurs during orthotopic liver transplantation (OLT particularly during the anhepatic phase. Although NaHCO3 is considered as the current standard therapy, there are numerous adverse effects. The aim of this study was to determine whether the restricted use of normal saline during anesthesia could reduce the need for NaHCO3. Methods: In this study we enrolled 75 patients with end-stage liver disease who underwent OLT from February 2010 until September 2010 at the Shiraz Organ Transplantation Center. Fluid management of two different transplant anesthetics were compared. The effect of restricted normal saline fluid was compared with non-restricted normal saline fluid on hemodynamic and acid-base parameters at three times during OLT: after the skin incision (T1, 15 min before reperfusion (T2, and 5 min after reperfusion (T3. Results: There were no significant differences in demographic characteristics of the donors and recipients (P>0.05. In the restricted normal saline group there was significantly lower central venous pressure (CVP than in the non-restricted normal saline group (P=0.002. No significant differences were noted in the other hemodynamic parameters between the two groups (P>0.05. In the non-restricted normal saline group arterial blood pH (P=0.01 and HCO3 (P=0.0001 were significantly less than the restricted normal saline group. The NaHCO3 requirement before reperfusion was significantly more than with the restricted normal saline group (P=0.001. Conclusion: Restricted normal saline administration during OLT reduced the severity of metabolic acidosis and the need for NaHCO3 during the anhepatic phase.

    Georg Dultz

    Full Text Available Chronic hepatitis C virus (HCV infection is a leading cause for orthotopic liver transplantation (OLT in the U.S. We investigated characteristics of HCV-infected patients registered for OLT, and explored factors associated with mortality. Data were obtained from the United Network for Organ Sharing and Organ Procurement and Transplantation network (UNOS/OPTN registry. Analyses included 41,157 HCV-mono-infected patients ≥18 years of age listed for cadaveric OLT between February 2002 and June 2014. Characteristics associated with pre- and post-transplant survival and time trends over the study period were determined by logistic and Cox proportional hazard regression analyses and Poisson regressions. Most patients were white (69.1% and male (70.8%. At waitlist registration, mean age was 54.6 years and mean MELD was 16. HCC was recorded in 26.9% of the records. A total of 51.2% of the patients received an OLT, 21.0% died or were too sick; 15.6% were delisted and 10.4% were still waiting. Factors associated with increased waitlist mortality were older age, female gender, blood type 0, diabetes, no HCC and transplant region (p<0.001. OLT recipient characteristics associated with increased risk for post OLT mortality were female gender, age, diabetes, race (p<0,0001, and allocation MELD (p = 0.005. Donor characteristics associated with waitlist mortality included age, ethnicity (p<0.0001 and diabetes (p<0.03. Waitlist registrations and OLTs for HCC significantly increased from 14.4% to 37.3% and 27.8% to 38.5%, respectively (p<0.0001. Pre- and post-transplant survival depended on a variety of patient-, donor-, and allocation- characteristics of which most remain relevant in the DAA-era. Still, intensified HCV screening strategies and timely and effective treatment of HCV are highly relevant to reduce the burden of HCV-related OLTs in the U.S.

    Purpose: To evaluate the efficacy and safety of percutaneous treatment of biliary strictures complicating orthotopic liver transplantation (OLT). Methods: Between October 1990 and May 2000, 619 patients underwent 678 liver transplants. Seventy of the 619 (11%) patients were found to be affected by biliary strictures by July 2000. Bilioplasty was performed in 51 of these 70 (73%) patients. A cohort of 33 of 51 (65%) patients were clinically followed for more than 12 months after the last percutaneous treatment and included in the survey results. Results: After one to three treatments 24 of 33 (73%)patients were stricture-free on ultrasound and MR cholangiography follow-up. A delayed stricture recurrence required a fourth percutaneous bilioplasty in two of 33 (6%) patients. A surgical bilioenteric anastomosis was performed in six of 33 (18%) patients.Retransplantation was performed due to ischemic damage in one of 33(3%) patients. Conclusion: Interventional radiology is an effective therapeutic alternative for the treatment of most biliary strictures complicating OLT. It has a high success rate and should be considered before surgical interventions. Elective surgery may be necessary in a few failed cases or those with more severe and extensive biliary strictures

    Purpose: This retrospective study was undertaken to evaluate the effectiveness of coronary stent placement in hepatic artery stenosis after orthotopic liver transplantation (OLT). Materials and methods: Of 430 consecutive adult orthotopic liver transplant recipients between November 2003 and September 2005, 17 had hepatic artery stenosis (HAS). Fourteen of them underwent coronary stent placement in the HAS. The technical results, complications, hepatic artery patency and clinical outcome were reviewed. Results: Technical and immediate success was 100%. After a mean follow-up of 159.4 days (range, 9-375 days), all patients obtained patent hepatic arteries except 2 patients occurred hepatic artery restenoses at 26 and 45 days after stent placement, respectively. Kaplan-Meier curve of patency showed cumulated stent patency at 3, 6, and 12 months of 78%, 58% and 45%, respectively. During the follow-up, 8 patients survived, 5 died of septic multiple-organ failure, 1 received retransplantation because of refractory biliary infection. Hepatic artery dissection induced by a guiding catheter occurred in one patient and was successfully treated with a coronary stent. Conclusion: Hepatic artery stenosis after OLT can be successfully treated with coronary stent placement with low complication rate and an acceptable 1-year hepatic artery patency rate

    Rotation thromboelastometry (TEM) has been proposed as a convenient alternative to standard coagulation tests in guiding the treatment of coagulopathy during orthotopic liver transplantation (OLT). This study was aimed at assessing the value of TEM in monitoring blood coagulation and guide transfusion support in OLT. Standard coagulation and TEM (EXTEM and FIBTEM) tests were performed at four preestablished intraoperative time points in 236 OLTs and prospectively recorded in a dedicated database together with the main operative and transfusion data. Transfusion thresholds were based on standard coagulation tests. Spearman's rank correlation (ρ), linear regression, and receiver operating characteristic curves were used when appropriate. EXTEM maximum clot firmness (MCF(EXTEM)) was the TEM variable that best correlated with the platelet (PLT) and fibrinogen levels (ρ = 0.62 and ρ = 0.69, respectively). MCF(FIBTEM) correlated with fibrinogen level (ρ = 0.70). EXTEM clot amplitude at 10 minutes (A10(EXTEM)) was a good linear predictor of MCF(EXTEM) (R(2) =0.93). The cutoff values that best predicted the transfusion threshold for PLTs and fibrinogen were A10(EXTEM) = 35 mm and A10(FIBTEM) = 8 mm. At these values, the negative and positive predictive accuracies of TEM to predict the transfusion thresholds were 95 and 27%, respectively. A10(EXTEM) is an adequate TEM variable to guide therapeutic decisions during OLT. Patients with A10(EXTEM) of greater than 35 mm are unlikely to bleed because of coagulation deficiencies, but using A10(EXTEM) of not more than 35 mm as the sole transfusion criterion can lead to unnecessary utilization of PLTs and fibrinogen-rich products. © 2012 American Association of Blood Banks.

  15. Liver Transplantation: Evolving Patient Selection Criteria

    Directory of Open Access Journals (Sweden)

    Andy S Yu

    2001-01-01

    Full Text Available 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.

    Liver transplantation is a treatment available for many patients with liver cirrhosis who find in this treatment a way to improve life expectancy and quality of life. Paranoid schizophrenia affects 1% of the general population, produces psychotic symptoms, and runs a chronic course in some cases with significant deterioration in all areas of life. To discuss the case of a patient with liver cirrhosis diagnosed with paranoid schizophrenia during the evaluation protocol for liver transplantation. Case report. We report the case of a 47-year-old woman with liver cirrhosis whose only alternative to improve life expectancy and quality of life was access to liver transplantation. During routine evaluations the liaison psychiatrist observed first-order psychotic symptoms and documented a life story that confirmed the presence of paranoid schizophrenia. Paranoid schizophrenia is a psychiatric disorder common in the general population that can be a part of the medical comorbidities of patients requiring liver transplantation and is not an absolute contraindication to its completion. We are unaware of similar cases of liver transplantation in patients with schizophrenia in our country. We believe this is a big step on the road to overcome the stigma that mental illness imposes on patients. Copyright © 2012 Asociación Colombiana de Psiquiatría. Publicado por Elsevier España.

    Full Text Available The article presents the experience of direct-acting antiviral (DAA drug treatment for hepatitis C in the patients after liver transplantation. The end-stage liver disease caused by hepatitis C is the main indication for orthotopic liver transplantation (OLT. In 2013, the first agent in the class of antiviral drugs directly acting on hepatitis C virus (HCV was introduced into clinical practice. That was sofosbuvir, a HCV polymerase inhibitor, that could be used without interferon alfa.Materials and methods. The study enrolled 33 liver transplant recipients with recurrent hepatitis C. Thirty-five courses of antiviral therapy (AT were conducted with sofosbuvir being one of AT components.Results. By the time of analysis, 21 patients had completed the antiviral therapy. All the patients showed an initial response to the antiviral therapy, HCV aviremia was achieved. In 3 patients, with the evaluable sustained virologic response (SVR, a renewed HCV replication was observed in the first weeks after the AT completion.Conclusion. The new direct-acting antiviral drugs offer an effective antiviral therapy to all liver graft recipients with recurrent HCV.

    There is growing interest in the quality of health care delivery in liver transplantation. Multiple stakeholders, including patients, transplant providers and their hospitals, payers, and regulatory bodies have an interest in measuring and monitoring quality in the liver transplant process, and understanding differences in quality across centres. This article aims to provide an overview of quality measurement and regulatory issues in liver transplantation performed within the United States. We review how broader definitions of health care quality should be applied to liver transplant care models. We outline the status quo including the current regulatory agencies, public reporting mechanisms, and requirements around quality assurance and performance improvement (QAPI) activities. Additionally, we further discuss unintended consequences and opportunities for growth in quality measurement. Quality measurement and the integration of quality improvement strategies into liver transplant programmes hold significant promise, but multiple challenges to successful implementation must be addressed to optimise value.

    Liver transplant is considered to be the last-resort treatment approach for pediatric patients with end-stage liver disease. Despite the remarkable advance in survival rates, liver transplant remains an intricate surgery with significant morbidity and mortality. Early diagnosis of complications is crucial for patient survival but is challenging given the lack of specificity in clinical presentation. Knowledge of the liver and vascular anatomy of the donor and the recipient or recipients before surgery is also important to avoid complications. In this framework, radiologists play a pivotal role on the multidisciplinary team in both pre- and postoperative scenarios by providing a road map to guide the surgery and by assisting in diagnosis of complications. The most common complications after liver transplant are (a) vascular, including the hepatic artery, portal vein, hepatic veins, and inferior vena cava; (b) biliary; (c) parenchymal; (d) perihepatic; and (e) neoplastic. The authors review surgical techniques, the role of each imaging modality, normal posttransplant imaging features, types of complications after liver transplant, and information required in the radiology report that is critical to patient care. They present an algorithm for an imaging approach for pediatric patients after liver transplant and describe key points that should be included in radiologic reports in the pre- and postoperative settings.

    2017-09-01

    Full Text Available The main features of liver failure are extensive necrosis of hepatocytes, rapid disease progression, and poor prognosis, and at present, there are no effective drugs and methods for the treatment of liver failure. This article summarizes four treatment methods for liver failure, i.e., medical treatment, cell transplantation, liver transplantation, and artificial liver support therapy, and elaborates on the existing treatment methods. The current medical treatment regimen should be optimized; cell transplantation has not been used in clinical practice; liver transplantation is the most effective method, but it is limited by donor liver shortage and high costs; artificial liver can effectively remove toxic substances in human body. Therefore, this article puts forward artificial liver as a transition for liver transplantation; artificial liver can buy time for liver regeneration or liver transplantation and prolong patients′ survival time and thus has a promising future. The new treatment modality of bioartificial liver combined with liver transplantation may bring good news to patients with liver failure.

    Full Text Available Abstract Objectives Chronic kidney disease is frequent in patients after orthotopic liver transplantation (OLT and has impact on survival. Patients receiving calcineurin inhibitors (CNI are at increased risk to develop impaired renal function. Early CNI reduction and concomitant use of mycophenolat mofetil (MMF has been shown to improve renal function. Methods The aim of this trial was to compare dose-reduced CNI/MMF versus CNI-free MMF/prednisone-based treatment in stable patients after OLT with respect to glomerular filtration rate (GFR. 21 patients [GFR 44.9 ± 9.9 mL/min/1.73 m2 measured by 99m-Tc-DTPA-clearance, serum creatinine (SCr 1.5 ± 0.42 mg/dL] were randomized either to exchange CNI for 10 mg prednisone (group 1; n = 8 or to receive CNI at 25% of the initial dose (group 2; n = 13 each in combination with 1000 mg MMF b.i.d. Results At month 12 mean SCr (-0.3 ± 0.4 mg/dL, p = 0.031 and GFR improved (8.6 ± 13.1 mL/min/1.73 m2, p = 0.015 in group 2 but remained unchanged in group 1. Main side effects were gastroinstestinal symptoms (14.3% and infections (4.8%. Two biopsy proven, steroid-responsive rejections occurred. In group 1 mean diastolic blood pressure (BP increased by 11 ± 22 mmHg (p = 0.03. Conclusions Reduced dose CNI in combination with MMF but not CNI-free-immunosuppression leads to improvement of GFR in patients with moderately elevated SCr levels after OLT. Addition of steroids resulted in increased diastolic blood pressure presumably counterbalancing the benefits of CNI withdrawal on renal function.

    Purpose: To analyze the results of stereotactic body radiation therapy (SBRT) in patients with early-stage, localized hepatocellular carcinoma who underwent definitive orthotopic liver transplantation (OLT). Methods and Materials: The subjects of this retrospective report are 38 patients diagnosed with hepatocellular carcinoma who underwent SBRT per institutional phase 1 to 2 eligibility criteria, before definitive OLT. Pre-OLT radiographs were compared with pathologic gold standard. Analysis of treatment failures and deaths was undertaken. Results: With median follow-up of 4.8 years from OLT, 9 of 38 patients (24%) recurred, whereas 10 of 38 patients (26%) died. Kaplan-Meier estimates of 3-year overall survival and disease-free survival are 77% and 74%, respectively. Sum longest dimension of tumors was significantly associated with disease-free survival (hazard ratio 1.93, P=.026). Pathologic response rate (complete plus partial response) was 68%. Radiographic scoring criteria performed poorly; modified Response Evaluation Criteria in Solid Tumors produced highest concordance (κ = 0.224). Explants revealed viable tumor in 74% of evaluable patients. Treatment failures had statistically larger sum longest dimension of tumors (4.0 cm vs 2.8 cm, P=.014) and non–statistically significant higher rates of lymphovascular space invasion (44% vs 17%), cT2 disease (44% vs 21%), ≥pT2 disease (67% vs 34%), multifocal tumors at time of SBRT (44% vs 21%), and less robust mean α-fetoprotein response (−25 IU/mL vs −162 IU/mL). Conclusions: Stereotactic body radiation therapy before to OLT is a well-tolerated treatment providing 68% pathologic response, though 74% of explants ultimately contained viable tumor. Radiographic response criteria poorly approximate pathology. Our data suggest further stratification of patients according to initial disease burden and treatment response.

    There are few reports on hepatitis C virus genotype 4 (HCV-4) recurrences after orthotopic liver transplantation (OLT). Therefore, we undertook a study to determine the epidemiological, clinical and virological characteristics of patients with biopsy-proven recurrent HCV infection and analyzed the factors that influence recurrent disease severity. We also compared disease recurrence and outcomes between HCV-4 and other genotypes. All patients who underwent OLT (locally or abroad) for HCV related hepatic cirrhosis from 1991 to 2006 and had recurrent HCV infection were identified. Clinical, laboratory and pathological data before and after OLT were collected and analyzed. Of 116 patients who underwent OLT for hepatitis C, 46 (39.7%) patients satisfied the criteria of recurrent hepatitis C. Twenty-nine (63%) patients were infected with HCV genotype 4. Mean (SD) for age was 54.9 (10.9) years. Nineteen of the HCV genotype 4 patients (65.5%) were males, 21 (72.4%) received deceased donor grafts, and 7 (24.1%) developed > - 1 acute rejection episodes. Pathologically, 7 (24.1%) and 4 (13.8%) patients had inflammation grade 3-4 and fibrosis stage 3-4, respectively. Follow-up biopsy in 9 (31%) HCV genotype 4 patients showed stable, worse and improved fibrosis stage in 5, 2 and 2 patients, respectively. Of the 7 patients in the recurrent HCV group who died, 6 were infected with genotype 4 and 4 of them died of HCV-related disease. This analysis suggests that HCV recurrence following OLT in HCV-4 patients is not significantly different from its recurrence for other genotypes. (author)

    Hepatocellular carcinoma is one of the main important causes of cancer-related death and its mortality is increasingly worldwide. In Europe, alcohol abuse accounts for approximately half of all liver cancer cases and it will become the leading cause of hepatocellular carcinoma in the next future with the sharp decline of chronic viral hepatitis. The pathophysiology of alcohol-induced carcinogenesis involves acetaldehyde catabolism, oxidative stress and chronic liver inflammation. Genetic background plays also a significant role and specific patterns of gene mutations in alcohol-related hepatocellular carcinoma have been characterized. Survival is higher in patients who undergo specific surveillance programmes than in patients who do not. However, patients with alcohol cirrhosis present a significantly greater risk of liver decompensation than those with cirrhosis due to other aetiologies. Furthermore, the adherence to screening program can be suboptimal. Liver transplant for patients with Milan-in hepatocellular carcinoma represents the best possible treatment in case of tumour recurrence/progression despite loco-regional or surgical treatments. Long-term result after liver transplantation for alcohol related liver disease is good. However, cardiovascular disease and de novo malignancies can significantly hamper patients' survival and should be carefully considered by transplant team. In this review, we have focused on the evolution of alcohol-related hepatocellular carcinoma epidemiology and risk factors as well as on liver transplantation in alcoholic patients with and without hepatocellular carcinoma.

    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. To report the occurrence of acute appendicitis in a cohort of liver transplant recipients. Retrospective analysis in a period of 12 years among 925 liver transplants, in witch five cases of acute appendicitis were encountered. 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. 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.

    Full Text Available Liver transplantation is an effective treatment for end-stage chronic liver diseases and acute liver failure. With the rapid development of surgical techniques, organ preservation technology, and pharmacotherapy, patients' survival rates are improved constantly. However, postoperative complications are still major influencing factors for postoperative incidence and mortality rates. Since clinical and laboratory examinations lack specificity and it is difficult to diagnose various postoperative complications, the application of imaging techniques effectively solves such problems. This article summarizes the imaging findings of common complications after liver transplantation, such as vascular complications, biliary complications, liver parenchyma lesions, and postoperative infection, and points out that imaging examinations have significant advantages and can be used for comprehensive evaluation of disease progression.

    Full Text Available Cyclosporin-A (CsA and tacrolimus (FK-506 are immunomodulating agents used to prevent rejection in organ transplantation. They are both associated with several side effects, including nephrotoxicity and severe hypertension due to vascular injury, which often appears as a microvascular occlusive disorder (thrombotic microangiopathy, TMA. We report the first case of a microvascular occlusive disorder with the features of TMA in the small bowel of an orthotopic liver transplant (OLT patient after immunosuppressive therapy with CsA and FK506. The patient presented with severe recurrent abdominal colics and distal subocclusion, requiring aggressive surgical treatment. Histological and ultrastructural analysis of the resected specimen disclosed intestinal TMA. Although rare, such a complication should be considered in the differential diagnosis of abdominal colics in patients undergoing immunosuppressant therapy after OLT.

Herein, we report an unusual case of a 58-year-old woman who experienced acute rejection at 30 months after OLT, only one case in which HNKHC resulted in MP pulse therapy for acute rejection in all 913 recipients in our center. The general morbidity of HNKHC was 1.09‰ in this study. HNKHC is characterized by rapid onset, rapid progression, and a lack of specific clinical manifestations. High-dose MP management was a clear risk factor. The principle of treatment included rapid rehydration, low-dose insulin infusion, and correcting disorders of electrolytes and acidosis. In conclusion, clinicians considering MP pulse therapy after OLT should be alert to the occurrence of HNKHC.

    Non-anastomotic biliary strictures (NAS) after orthotopic liver transplantation (OLT) have a negative influence on graft survival. Expert opinion suggests a negative effect of NAS on other important aspects of post-transplant care, although its impact is largely unknown as data are scarce. This retrospective single center study analyzed data on healthcare consumption, use of ionizing radiation, infectious complications and development of highly resistant microorganisms (HRMO) in adult patients with NAS. A comparison with a matched control group was made. Forty-three liver recipients with NAS and 43 controls were included. Hospital admissions were higher in patients with NAS. Most common reason for admission was bacterial cholangitis (BC), with 70% of the patients having at least one episode compared to 9% in the control group. In patients with NAS, 67% received at least one ERCP compared to 21% in the control group (p = 0.001). This resulted in a larger yearly received radiation dose for patients with NAS (p = 0.001). Frequency of intravenous antibiotic therapy was higher (p = 0.001) for patients with NAS, consistently resulting in a higher number of cultures found with HRMO (p = 0.012). NAS after OLT have a negative effect on post-transplant care, increasing readmission rates, interventional procedures, exposure to ionizing radiation, use of antibiotics, and development of HRMO. © 2015 John Wiley & Sons A/S.

    Orthotopic liver transplantation (OLT) and resection are effective treatments for hepatocellular carcinoma (HCC). However, optimizing OLT and limiting HCC recurrence remains a vexing problem. New HCC MELD and allocation algorithms provide greater observation of HCC patients, many while receiving local-regional treatments. Potential benefits of local-regional treatment for limiting HCC recurrence post-OLT remain incompletely understood. Therefore we aimed to define HCC specific prognostic factors affecting recurrence in a contemporary, multi-center cohort of HCC patients undergoing OLT and specifically whether local-regional therapies limited recurrence. We identified 441 patients undergoing OLT for HCC at three major transplant centers from 2008-2013. Cox regression was used to analyze covariate-adjusted recurrence and mortality rates post-OLT. "Bridging" or "down-staging" therapy was used in 238 patients (54%) with transarterial chemoembolization (TACE) being used in 170 (71%) of treated patients. The survival rate post-OLT was 88% and 78% at 1 and 3 years, respectively, with HCC recurrence (28% of deaths) significantly increasing mortality rate (HR=19.87, pOLT. Local-regional therapy to achieve a pathologic response (decreasing tumor size) can limit HCC recurrences post-OLT. This article is protected by copyright.

    Objective To longitudinally investigate the role of FoxP3+ Regulatory T cells (Treg) and interleukin17-producing T helper 17 cells (Th17) in De Novo Hepatitis B Virus infection after orthotopic Liver Transplantation (DNHB-OLT), and analyze the possible correlation between these cells and HBV clearance of the disease. Methods We enrolled 12 control cases after orthotopic Liver Transplantation (OLT) and 24 patients, including 12 diagnosed with DNHB-OLT and 12 diagnosed with Acute Hepatitis B Virus infection (AHB), into the study from the liver transplantation and research center at Beijing 302 Hospital. Flow cytometry was used to detect the frequencies of Treg and Th17, and ELISA was applied to detect the concentration of IL6, IL22, TGF-β and IL2 in peripheral blood. We also measured the gene expression level by real time-quantitative PCR and protein expression using immunohistochemistry and western-blot. Furthermore, we divided DNHB-OLT patients into the clearance and non-clearance groups and examined longitudinally Th17, Treg cells at different times. Results The percentage of Treg cells, expression of FoxP3 mRNA and related anti-inflammatory cytokines such as IL2 and TGF-β1 in the DNHB-OLT group were significantly higher than that in the AHB and OLT groups. The percentage of Th17 cells, expression of RORγt mRNA and related pro-inflammatory cytokines such as IL17 and IL22 in the DNHB-OLT group were significantly lower than that in the AHB group, but the levels of these cytokines are very similar to the OLT group. The ratios of Treg to Th17 in the DNHB-OLT group were significantly higher than that in the OLT and AHB groups. Treg frequencies significantly correlated with HBV DNA, whereas IL17 frequencies didn’t significantly correlate with ALT. In DNHB-OLT patients, the clearance group was accompanied by a rapid increase in the Th17 cells during the first 4th week and afterwards continuously decrease to the control group, together with a continuously decrease in

    We investigated the diversity of central nervous system complications after liver transplantation in terms of clinical manifestations and temporal course. Liver transplantation is a lifesaving option for end stage liver disease patients but post-transplantation neurologic complications can hamper recovery. Between 1 January 2001 and 31 December 2010, patients who had undergone liver transplantation at a single tertiary university hospital were included. We reviewed their medical records and brain imaging data and classified central nervous system complications into four categories including vascular, metabolic, infectious and neoplastic. The onset of central nervous system complications was grouped into five post-transplantation intervals including acute (within 1 month), early subacute (1-3 months), late subacute (3-12 months), chronic (1-3 years), and long-term (after 3 years). During follow-up, 65 of 791 patients (8.2%) experienced central nervous system complications, with 30 occurring within 1 month after transplantation. Vascular etiology was the most common (27 patients; 41.5%), followed by metabolic (23; 35.4%), infectious (nine patients; 13.8%), and neoplastic (six patients). Metabolic encephalopathy with altered consciousness was the most common etiology during the acute period, followed by vascular disorders. An initial focal neurologic deficit was detected in vascular and neoplastic complications, whereas metabolic and infectious etiologies presented with non-focal symptoms. Our study shows that the etiology of central nervous system complications after liver transplantation changes over time, and initial symptoms can help to predict etiology.

    Stockland, A. H.; Walser, E. M.; Paz-Fumagalli, R.; McKinney, J. M.; May, G. R.

    2007-01-01

    Our purpose was to compare the recurrence rate and survival in patients with hepatocellular carcinoma (HCC) who had elective transarterial chemoembolization (TACE), immediate preoperative TACE, or no treatment prior to orthotopic liver transplantation (OLT). A total of 132 patients with HCC had TACE prior to OLT. Eighteen patients had no TACE before OLT and functioned as a control group. The urgent group included 35 patients embolized less than 24 h before OLT and the elective group included 97 patients embolized greater than 1 day before transplantation. These groups were compared with regard to tumor staging, hepatic synthetic function, and post-TACE tumor necrosis and survival and recurrence rates.Patients were followed for a mean of 780 days post OLT (1-2912 days). The tumor staging was similar between groups but the Childs-Pugh score in the urgent and untreated group was significantly higher than that of the other groups. The degree of necrosis at explant was also significantly different between the two treated groups, with an average 35% necrosis in the patients embolized less than 24 h before OLT vs 77% in the elective group (p < 0.002). Recurrence rate in the urgent group was 8 of 35 (23%) in a median of 580 days, 20 of 97 (21%) in a median of 539 days in the elective group, and 2 of 18 (11%) in a median of 331 days in the no-TACE group. Survival at 1, 3, and 5 years was 91%, 80%, and 72% in the elective group, 79%, 58%, and 39% in the urgent group, and 69%, 61%, and 41% in the no-TACE group, respectively. The urgent and no-TACE groups had significantly worse survival compared with the other groups; however, the tumor recurrence rates were statistically the same among all three groups. TACE within 24 h of OLT causes an average of 35% necrosis and elective TACE increases necrosis further to 77%. Despite this difference, the tumor recurrence rate in the three groups is equivalent and no different from that in the group that received no treatment before OLT

    Background In order to receive a liver transplant, patients must first be placed on the waiting list – a decision made in most transplant centers by a multidisciplinary committee. The function of these committees has never been studied. Objectives To describe decision making in liver transplant committees and identify opportunities for process improvement. Design Observational multi-center Setting We observed 63 meetings and interviewed 50 committee members at 4 liver transplant centers. Study Subjects Transplant committee members. Measurements Recorded transcripts and field notes were analyzed using standard qualitative sociological methods. Results While the structure of meetings varied by center, the process was uniform and involved reviewing possible reasons for patient exclusion using primarily inductive reasoning. Stated justifications for excluding patients were a) too well, b) non-hepatic comorbidities or advanced age, c) too sick in the setting of advanced liver disease, d) substance abuse, or e) other psychosocial barriers. Dominant themes identified included members’ angst over deciding who lives and dies, a high correlation between psychosocial barriers to transplant and patients’ socioeconomic status, and the influence of external forces on decision making. Consistently identified barriers to effective group decision making were: 1) unwritten center policies, and 2) confusion regarding advocacy versus stewardship roles. Limitations The use of qualitative methods provides broad understanding but limits specific inferences. These four centers may not be reflective of every transplant center nationwide. Conclusion The difficult decisions made by these committees are reasonably consistent and always well-intentioned, but might be improved by more explicit written policies and clarifying roles. This process may help inform resource allocation in other areas of medicine. Primary funding source The Greenwall Foundation. PMID:22007044

    Orthotopic liver transplantation (OLT) is the choice of treatment not only for end-stage liver disease and acute liver failure but also for hepatocellular carcinoma (HCC). The development of de novo malignancies after liver transplantation plays an important role in late mortality; the incidence of late mortality has increased owing to improved survival. The incidence of de novo malignancies is 2.3% to 25%, which is 2 to 3 times that of malignancies in the general population. The most commonly reported de novo malignancies in solid organs are skin cancer, Karposi sarcoma, and colon cancer according to the frequency of exposure to a specific carcinogen. We hypothesized that exposure to different carcinogens would change the distribution of de novo malignancies among patients after OLT. In Taiwan, 10% of the population is exposed to a unique carcinogen, the betel quid, which is associated with a high incidence of head and neck cancer (HNC) among the Taiwanese population.From 2004 to 2014, we retrospectively reviewed 484 cases post-OLT at our institution and 16 patients with 17 de novo malignancies were identified. Most of the patients had HNC, which is in contrast to previous literature reports.Univariate and multivariate analyses identified betel quid chewing as the main leading factor for HNC in the Taiwanese population.Routine screening of the oral mucosa in patients with the habit of betel quid chewing is recommended in Taiwan for the early detection of HNC. Routine screening with aggressive treatment after diagnosis of HNC in patients with the habit of chewing betel quid, who underwent OLT, resulted in good patient prognosis.

    The filed of liver transplantation (LT) continues to evolve and is highly effective therapy for many patients with acute and chronic liver failure resulting from a variety of causes. Improvement of perioperative care, surgical technique and immunosuppression in recent years has led to its transformation into a safe and routine procedure with steadily improving results. The aim of this paper is to present the initial experience of the transplant team at Military Medical Academy - Sofia, Bulgaria. For the period of April 2007 - August 2014 the team performed 38 liver transplants in 37 patients (one retransplantation). Patients were followed up prospectively and retrospectively. In 36 (95%) patients a graft from a cadaveric donor was used and in two cases--a right liver grafts from live donor. The mean MELD score of the transplanted patients was 17 (9-40). The preferred surgical technique was "piggyback" with preservation of inferior vena cava in 33 (86%) of the cases and classical technique in 3 (8%) patients. The overall complication rate was 48%. Early mortality rate was 13% (5 patients). The overall 1- and 5-year survival is 81% and 77% respectivelly. The setting of a new LT program is a complex process which requires the effort and effective colaboration of a wide range of speciacialists (hepatologists, surgeons, anesthesiologists, psychologists, therapists, coordinators, etc.) and institutions. The good results are function of a proper selection of the donors and the recipients. Living donation is an alternative in the shortage of cadaveric donors.

    Full Text Available Acute lung injury (ALI is a severe complication of orthotopic liver transplantation (OLT with unclear underline mechanism. Toll-like receptor 4 (TLR4 has been identified as a key receptor mediating inflammation. We hypothesized that TLR4-mediated pulmonary inflammation may contribute to development of ALI during OLT. Patients with or without ALI were observed for serum cytokines and expression of TLR4 on peripheral blood polymorphonuclear leukocytes (PMNs. Next, rats which underwent orthotopic autologous liver transplantation (OALT were divided into sham and model groups. Pulmonary function and the level of TLR4 expression and cytokines were analyzed. Furthermore, the role of TLR4 in OALT-mediated ALI was assessed in rats treated with TLR4-siRNA before OALT. The PMNs TLR4 expression and the serum TNF-α and IL-β level were higher in patients with ALI than those with non-ALI. Interestingly, lung TLR4 expression was significantly increased after 8 hours of OALT with increased levels of TNF-α and IL-β, which lead to lung pathological damage and an increase of lung myeloperoxidase content. Moreover, knockdown of TLR4 reduced lung cytokines release and reversed the above pathologic changes after OALT and finally improved rats’ survival rate. In conclusion, TLR4 overexpression, potentially by stimulating proinflammatory cytokine overproduction, contributes to the development of ALI after OLT.

    In cases of chronic renal insufficiency, successful kidney transplantation is the method of choice to restore patients' health, well-being and physical fitness. The interdisciplinary collaboration of nephrologists and transplant surgeons has always been a prerequisite for the successful pre-, peri- and post-transplant care of renal transplant patients. The same holds true for liver transplant patients. Here the nephrologist is often involved in cases requiring pre- or post-transplant dialysis as well as in decision making for combined liver-kidney transplantation. This review focuses on nephrological aspects in patient care before and after kidney and liver transplantation. Georg Thieme Verlag KG Stuttgart · New York.

    Determining the indications for and timing of liver transplantation (LT) for acute liver failure (ALF) is essential. The King's College Hospital (KCH) guidelines and Japanese guidelines are used to predict the need for LT and the outcomes in ALF. These guidelines' accuracy when applied to ALF in different regional and etiological backgrounds may differ. Here we compared the accuracy of new (2010) Japanese guidelines that use a simple scoring system with the 1996 Japanese guidelines and the KCH criteria for living donor liver transplantation (LDLT). We retrospectively analyzed 24 adult ALF patients (18 acute type, 6 sub-acute type) who underwent LDLT in 1998-2009 at our institution. We assessed the accuracies of the 3 guidelines' criteria for ALF. The overall 1-year survival rate was 87.5%. The new and previous Japanese guidelines were superior to the KCH criteria for accurately predicting LT for acute-type ALF (72% vs. 17%). The new Japanese guidelines could identify 13 acute-type ALF patients for LT, based on the timing of encephalopathy onset. Using the previous Japanese guidelines, although the same 13 acute-type ALF patients (72%) had indications for LT, only 4 patients were indicated at the 1st step, and it took an additional 5 days to decide the indication at the 2nd step in the other 9 cases. Our findings showed that the new Japanese guidelines can predict the indications for LT and provide a reliable alternative to the previous Japanese and KCH guidelines.

    Hepatic steatosis develops after liver transplantation (LT) in 30% of adults, and nonalcoholic fatty liver disease (NAFLD) is the most common chronic liver disease in nontransplanted children. However, posttransplant steatosis has been minimally studied in pediatric LT recipients. We explored the prevalence, persistence, and association with chronic liver damage of hepatic steatosis in these children. In this single-center study of pediatric patients transplanted 1988-2015 (n = 318), 31% of those with any posttransplant biopsy (n = 271) had ≥ 1 biopsy with steatosis. Median time from transplant to first biopsy with steatosis was 0.8 months (interquartile range [IQR], 0.3-6.5 months) and to last biopsy with steatosis was 5.5 months (IQR, 1.0-24.5 months); 85% of patients with steatosis also had for-cause biopsies without steatosis. All available for-cause biopsies were re-evaluated (n = 104). Of 9 biopsies that could be interpreted as nonalcoholic steatohepatitis (NASH)/borderline NASH, with steatosis plus inflammation or ballooning, 8 also had features of cholestasis or rejection. Among 70 patients with surveillance biopsies 3.6-20.0 years after transplant, only 1 overweight adolescent had a biopsy with NAFLD (grade 1 steatosis, mild inflammation, no ballooning or fibrosis)-despite a 30% prevalence of overweight/obesity in the cohort and 27% with steatosis on previous for-cause biopsy. Steatosis on preceding for-cause biopsy was not associated with portal (P = 0.49) or perivenular fibrosis (P = 0.85) on surveillance biopsy. Hepatic steatosis commonly develops early after transplant in children and adolescents, but it rarely persists. Biopsies that did have steatosis with NASH characteristics were all for-cause, mostly in patients with NAFLD risk factors and/or confounding causes of liver damage. Prospective studies that follow children into adulthood will be needed to evaluate if and when hepatic steatosis presents a longterm risk for

    The harvesting of livers for transplantation involves assessment of the liver's suitability, including an examination of the colour and general appearance of the liver. If the organ is to be split for transplantation into two recipients, the vasculature of the liver must be studied and recorded. Remote assessment of livers and telesurgical guidance could save time and money. This thesis highlights the importance of colour in liver diagnosis, using animal and human models to examine the colour...

    Summary Budd-Chiari syndrome involves obstruction of hepatic venous outflow tracts at various levels from small hepatic veins to the inferior vena cava and is the result of thrombosis or its fibrous sequelae. There is a conspicuous difference in its etiology in the West and the East. Myeloproliferative disease predominates in the West and obstruction of the vena cava predominates in the East. The clinical presentation and clinical manifestations are so varied that it should be suspected in any patient with acute or chronic liver dysfunction. It should be treated with step-wise management. First-line therapy should be anticoagulation with medical treatment of the underlying illness, and interventional revascularization and TIPS are indicated in the event of a lack of response to medical therapy. Liver transplantation may be indicated as a rescue treatment or for fulminant cases with promising results. This step-by-step strategy has achieved a 5-year transplant-free survival rate of 70% and a 5-year overall survival rate of 90%. Living donor liver transplantation can also be used for patients with Budd-Chiari syndrome if deceased donor livers are scarce, but it requires a difficult procedure particularly with regard to venous outflow reconstruction.

    Full Text Available Bone mineral density (BMD was estimated twice in 18 recipents of ortotopic liver transplantation. There was decreased BMD in axial so as in peripheral skeleton in early time and in vertebral or hip Ward triangle in late time following transplantation being lower in primary biliary cirrosis then in cirrosis following chronic virus hepatitis despite tacrolimus immunosupression without prednisolon. Tacrolimus immunosupression with prednisolon in primary biliary cirrosis patients in late postoperative time was associated with hard BMD lowering which correlated with glucocorticoid therapy duration and prednisolon cumulative dosis.

    Full Text Available Orthotopic liver transplantation (OLT is the only treatment for many patients with end-stage chronic liver diseases. In patients with complete vena cava inferior (VCI cross-clamping veno-venous bypass (VVB is either used or not depending on the indications. The case management of the patient with complete VCI cross-clamping depends on the initial state of the recipient and the transplant team’s opinion.Aim. To compare the perioperative period of OLT depending on the method to conduct the main stage of the surgery: with the use of veno-venous bypass and without it with complete VCI cross-clamping.Materials and methods. In Group 1 (n = 20, OLT was performed without VVB with complete VCI cross-clamping; in Group 2 (n = 26, the surgery was conducted with veno-venous bypass. Patients in both groups were similar in age (46.15 ± 10.22 and 47.3 ± 9.29, respectively, in severity of the disease: Child-Pugh (10.15 ± 1.42 and 10.19 ± 2.45, MELD 16.47 ± 4.41 and 15.8 ± 4.95.Results. We determined and evaluated hemodynamic parameters, oxygen transport, the quantitative and qualitative infusion composition, urine output, characteristics of the postoperative period.Conclusion. Our data show that changes in hemodynamic and oxygen transport are associated with reperfusion syndrome and do not depend on the method of transplantation. At the same time, it reduces the blood loss, time of surgery, and the duration of postoperative mechanical ventilation and stay in the ICU after liver transplantation in patients without veno-venous bypass.

    Objective: Developing strategies for transfusion-free live donor liver transplantation in Jehovah's Witness patients. Summary Background Data: Liver transplantation is the standard of care for patients with end-stage liver disease. A disproportionate increase in transplant candidates and an allocation policy restructuring, favoring patients with advanced disease, have led to longer waiting time and increased medical acuity for transplant recipients. Consequently, Jehovah's Witness patients, who refuse blood product transfusion, are usually excluded from liver transplantation. We combined blood augmentation and conservation practices with live donor liver transplantation (LDLT) to accomplish successful LDLT in Jehovah's Witness patients without blood products. Our algorithm provides broad possibilities for blood conservation for all surgical patients. Methods: From September 1998 until June 2001, 38 LDLTs were performed at Keck USC School of Medicine: 8 in Jehovah's Witness patients (transfusion-free group) and 30 in non-Jehovah's Witness patients (transfusion-eligible group). All transfusion-free patients underwent preoperative blood augmentation with erythropoietin, intraoperative cell salvage, and acute normovolemic hemodilution. These techniques were used in only 7%, 80%, and 10%, respectively, in transfusion-eligible patients. Perioperative clinical data and outcomes were retrospectively reviewed. Data from both groups were statistically analyzed. Results: Preoperative liver disease severity was similar in both groups; however, transfusion-free patients had significantly higher hematocrit levels following erythropoietin augmentation. Operative time, blood loss, and postoperative hematocrits were similar in both groups. No blood products were used in transfusion-free patients while 80% of transfusion-eligible patients received a median of 4.5+/− 3.5 units of packed red cell. ICU and total hospital stay were similar in both groups. The survival rate was 100% in

    Full Text Available The liver is the largest gland and, apart from the skin, also the biggest organ in the body. They are a central laboratory for processing proteins, carbohidrates and fat, and they also detoxify our body.Liver failure is a result of cronic or acute liver disease or hepatic impairment. Many diseases of the liver are accompained by icterus as a result of increased level of bilirubin in the system. Today we can live without other organs important for metabolism, such as eg. the kidney or pancreas, because their function can be replaced. But we cannot live without the liver because their functions are too varied and complex. Therefore, when we have incurable disease of the liver we need liver transplantation.Life with a child who needs liver transplantation is very hard for all family members. Especially at the begining of treatment, life for all family members, and in particular for the parents, is very stressfull.Nurses must have sufficinet knowledge, she should be able to talk to parents in plain language with a high degree of optimism. We make them feel that they are not alone and we encourage them. Nurses must believe in successful treatment, so that they can inspire courage in parents.Quality of life is not in perfection, but rather in the way how we manage to live with imperfection. A person who is in any way affected, can perceive his quality of life as very good. Here, his personal attitude and attitude to his surrondings is most important. This is a higher quality than that obtainable by knowledge alone and which can be measured or evaluated.

    The liver's role as the largest organ of metabolism and the unique and often critical function of liver-specific enzyme pathways imply a greater risk to the recipient of acquiring a donor metabolic disease with liver transplants versus other solid organ transplants. With clinical consequences rarely reported, the frequency of solid organ transplant transfer of metabolic disease is not known. Ornithine transcarbamylase deficiency (OTCD), although rare, is the most common of the urea cycle disorders (UCDs). Because of phenotypic heterogeneity, OTCD may go undiagnosed into adulthood. With over 5000 liver transplant procedures annually in the United States, the likelihood of unknowingly transmitting OTCD through liver transplantation is very low. We describe the clinical course of a liver transplant recipient presenting with acute hyperammonemia and encephalopathy after receiving a liver graft form a donor with unrecognized OTCD.

    From 1988 to June 2000 138 transplantations were performed in 129 adult patients. Actuarial patient and graft survivals have been 80.7% and 75.4% at one year and 67.8% and 63.5% at 10 years. This compares favourably with the statistics of the European Liver Transplant Registry that collected data from more than 30,000 grafts. Over the twelve years of activity, the indications have become more liberal and the techniques have been simplified. The waiting list has therefore grown and some patients are now unfortunately dying before a graft can be found because the number of brain dead donors remains stable. In order to palliate this shortage, older donors are now being accepted even with co-morbidities and/or moderate alterations of the liver function tests. The use of live donors and the split of the best cadaveric grafts for two recipients will also reduce the gap between the demand and the offer.

    Full Text Available Abstract Background Immunosuppression with calcineurin inhibitors (CNI increases the risk of renal dysfunction after orthotopic liver transplantation (OLT. Controlled trials have shown improvement of renal function in patients that received delayed and/or reduced-dose CNI after OLT. Delaying immunosuppression with CNI in combination with induction therapy does not increase the risk of acute rejection but reduces the incidence of acute renal dysfunction. Based on this clinical data this study protocol was designed to assess the efficacy and safety of calcineurin-inhibitor-free de-novo immunosuppression after liver transplantation. Methods/Design A prospective therapeutic exploratory, non-placebo controlled, two stage monocenter trial in a total of 29 liver transplant patients was designed to assess the safety and efficacy of de-novo CNI-free immunosuppression with basiliximab, mycophenolate sodium, prednisolone and everolimus. The primary endpoint is the rate of steroid resistant rejections. Secondary endpoints are the incidence of acute rejection, kidney function (assessed by incidence and duration of renal replacement therapy, incidence of chronic renal failure, and measurement glomerular filtration rate, liver allograft function (assessed by measurement of AST, ALT, total bilirubin, AP, GGT, treatment failure, (i. e., re-introduction of CNI, incidence of adverse events, and mortality up to one year after OLT. Discussion This prospective, two-stage, single-group pilot study represents an intermediate element of the research chain. If the data of the phase II study corroborates safety of de-novo CNI-free immunosuppressive regimen this should be confirmed in a randomized, prospective, controlled double-blinded clinical trial. The exploratory data from this trial may then also facilitate the design (e. g. sample size calculation of this phase III trial. Trial registration number NCT00890253 (clinicaltrials.gov

    Full Text Available Background: During orthotopic liver transplantation (OLT, activation of the fibrinolytic system can contribute significantly to perioperative bleeding. Prophylactic administration of antifibrinolytic agents has been shown to reduce blood loss and the need for allogenic transfusion. Objective: To study the effect of antifibrinolytics on requirement of blood components, blood loss and operative time during OLT in patients with end stage liver disease, reporting to a single centre. Materials and Methods: Consecutive patients who underwent OLT at this centre during the period February 2003-October 2007 were the subjects of this study. Based on the individual anesthesiologist′s preference, patients were assigned to receive either two million units of aprotinin (AP as a bolus followed by 5,00,000 units/hour or 10 mg/kg tranexamic acid (TAas a bolus followed by 10 mg/kg every six to eight hours, administered from the induction till the end of the surgery. Transfusion policy was standardized in all patients. Intraoperative red cell salvage was done wherever possible. The effect of these two antifibrinolytic drugs on transfusion requirement was evaluated as a whole and in a sub group of patients from each treatment group and compared with a concurrent control group that did not receive antifibrinolytic drugs. Results: Fifty patients (40 M / 10 F, 44 adults, 6 pediatric patients underwent OLT in the study period. Fourteen patients were given AP, 25 patients were given TA and 11 patients did not receive any of the agents(control group. The median volume of total blood components transfused in antifibrinolytic group (n=39 was 4540 ml(0-19,200ml, blood loss 5 l(0.7-35l and operative time 9h (4.5-17h and that of control group(n=11 was 5700 ml(0-15,500ml, 10 l(0.6-25 l and 9h (6.4-15.8h respectively.

    Perioperative thermal disturbances during orthotopic liver transplantation (OLT) are common. We hypothesized that in patients undergoing OLT the use of a humidified high flow CO 2 warming system maintains higher intraoperative temperatures when compared to standardized multimodal strategies to maintain thermoregulatory homeostasis. We performed a randomized pilot study in adult patients undergoing primary OLT. Participants were randomized to receive either open wound humidification with a high flow CO 2 warming system in addition to standard care (Humidification group) or to standard care alone (Control group). The primary end point was nasopharyngeal core temperature measured 5 min immediately prior to reperfusion of the donor liver (Stage 3 - 5 min). Secondary endpoints included intraoperative PaCO 2 , minute ventilation and the use of vasoconstrictors. Eleven patients were randomized to each group. Both groups were similar for age, body mass index, MELD, SOFA and APACHE II scores, baseline temperature, and duration of surgery. Immediately prior to reperfusion (Stage 3 - 5 min) the mean (SD) core temperature was higher in the Humidification Group compared to the Control Group: 36.0 °C (0.13) vs. 35.4 °C (0.22), p = 0.028. Repeated measured ANOVA showed that core temperatures over time during the stages of the transplant were higher in the Humidification Group compared to the Control Group (p < 0.0001). There were no significant differences in the ETCO 2 , PaCO 2 , minute ventilation, or inotropic support. The humidified high flow CO 2 warming system was superior to standardized multimodal strategies in maintaining normothermia in patients undergoing OLT. Use of the device was feasible and did not interfere with any aspects of surgery. A larger study is needed to investigate if the improved thermoregulation observed is associated with improved patient outcomes. ACTRN12616001631493 . Retrospectively registered 25 November 2016.

    Post-transplantation portal hypertension has severe complications, such as esophageal varix bleeding, therapy refractory ascites, extreme splenomegaly, and graft dysfunction. The aim of our study was to analyze the effectiveness of the therapeutic strategies and how to visualize the procedure. A retrospective study involving liver transplantation patients from the Semmelweis University Department of Transplantation and Surgery was performed between 2005 and 2015. The prevalence, etiology, and leading complications of the condition were determined. The applied interventions' effects on the patients' ascites volume, splenic volume, and the occurrence of variceal bleeding were determined. Mean portal blood flow velocity and congestion index values were calculated using Doppler ultrasonography. The prevalence of post-transplantation portal hypertension requiring intervention was 2.8%. The most common etiology of the disease was portal anastomotic stenosis. The most common complications were esophageal varix bleeding and therapy refractory ascites. The patients' ascites volume decreased significantly (2923.3 ± 1893.2 mL vs. 423.3 ± 634.3 mL; P portal hypertension. After the interventions, these parameters shifted towards the physiologic ranges. The interventions performed in our clinic were effective in most cases. The patients' ascites volume, splenic volume, and the prevalence of variceal bleeding decreased after the treatment. Doppler ultrasonography has proved to be a valuable imaging modality in the diagnosis and the follow-up of post-transplantation portal hypertension. Copyright © 2017 Elsevier Inc.

    The Kings College group was the first to describe a clinical syndrome similar to autoimmune hepatitis in children and young adults transplanted for non-immune mediated liver diseases. They coined the term "de novo autoimmune hepatitis". Several other liver transplant centres confirmed this observation. Even though the condition is uncommon, patients with de novo AIH are now seen in most of the major transplant centres. The disease is usually characterized by features of acute hepatitis in otherwise stable transplant recipients. The most characteristic laboratory hallmark is a marked hypergammaglobulinaemia. Autoantibodies are common, mostly ANA. We described also a case of LKM1-positivity in a patients transplanted for Wilson's disease, however this patients did not develop clinical or histological features of AIH. Development of SLA/LP-autoantibodies is also not described. Therefore, serologically de novo AIH appears to correspond to type 1 AIH. Like classical AIH patients respond promptly to treatment with increased doses of prednisolone and azathioprine, while the calcineurin inhibitors cyclosporine or tacrolimus areof very limited value - which is not surprising, as almost all patients develop de novo AIH while receiving these drugs. Despite the good response to treatment, most patients remain a clinical challenge as complete stable remissions are uncommon and flares, relapses and chronic disease activity can often occur. Pathogenetically this syndrome is intriguing. It is not clear, if the immune response is directed against allo-antigens, neo-antigens in the liver, or self-antigens, possibly shared by donor and host cells. It is very likely that the inflammatory milieu due to alloreactive cells in the transplanted organ contribute to the disease process. Either leading to aberrant antigen presentation, or providing co-stimulatory signals leading to the breaking of self-tolerance. The development of this disease in the presence of treatment with calcineurin

    To address endoscopic outcomes of post-Orthotopic liver transplantation (OLT) patients diagnosed with a "redundant bile duct" (RBD). Medical records of patients who underwent OLT at the Liver Transplant Center, University Texas Health Science Center at San Antonio Texas were retrospectively analyzed. Patients with suspected biliary tract complications (BTC) underwent endoscopic retrograde cholangiopancreatography (ERCP). All ERCP were performed by experienced biliary endoscopist. RBD was defined as a looped, sigmoid-shaped bile duct on cholangiogram with associated cholestatic liver biomarkers. Patients with biliary T-tube placement, biliary anastomotic strictures, bile leaks, bile-duct stones-sludge and suspected sphincter of oddi dysfunction were excluded. Therapy included single or multiple biliary stents with or without sphincterotomy. The incidence of RBD, the number of ERCP corrective sessions, and the type of endoscopic interventions were recorded. Successful response to endoscopic therapy was defined as resolution of RBD with normalization of associated cholestasis. Laboratory data and pertinent radiographic imaging noted included the pre-ERCP period and a follow up period of 6-12 mo after the last ERCP intervention. One thousand two hundred and eighty-two patient records who received OLT from 1992 through 2011 were reviewed. Two hundred and twenty-four patients underwent ERCP for suspected BTC. RBD was reported in each of the initial cholangiograms. Twenty-one out of 1282 (1.6%) were identified as having RBD. There were 12 men and 9 women, average age of 59.6 years. Primary indication for ERCP was cholestatic pattern of liver associated biomarkers. Nineteen out of 21 patients underwent endoscopic therapy and 2/21 required immediate surgical intervention. In the endoscopically managed group: 65 ERCP procedures were performed with an average of 3.4 per patient and 1.1 stent per session. Fifteen out of 19 (78.9%) patients were successfully managed with

    Little information is available about anesthesia management of nontransplant organ surgery of recipients after adult liver transplantation. The aim of this study was to discuss the anesthesia management of recipients for different stages after liver transplantation. The medical records of 16 patients were reviewed after OLT scheduled for elective nontransplant organ surgery at our institution from September 2002 to October 2005. The patients were divided into perioperative stage (group A) and mid-term and long-term stage (group B) groups according to post-OLT time. The data of 16 patients preoperation, intraoperation and postoperation were analyzed. The measurements of alanine transaminase (ALT), total bilirubin (TB), prothrombin time (PT), and lung infection were significantly higher in group A than in group B (POLT recipients except for contraindications. Special considerations include protection of the function of important organs, correction of hemodynamic instability in perioperative stage patients after OLT, and measurement of the side-effects of immunosuppression in mid-term and long-term stage patients.

    Recurrent hepatitis C (RHC) in orthotopic liver transplantation (OLT) population is associated with accelerated rates of fibrosis, low efficacy and decreased tolerability with traditional therapies. The aim of this study was to evaluate the safety and efficacy of ledipasvir/sofosbuvir (LED/SOF) with or without ribavirin (RBV) in OLT patients with RHC. Patients at least 3 months post-OLT and with documented RHC were treated with LED/SOF with or without RBV for either 12 or 24 weeks. End-of-treatment and sustained virological response 12 weeks after the completion of treatment were documented. Patients were closely monitored for treatment-related adverse effects and the potential need for adjustment in their immunosuppression. Seventy-one patients were included in the study. Median age was 62 years. Median time from OLT was 55 months. Twenty-six (36.6%) patients were treatment-naive and 45 (63.4%) had previously failed interferon-based therapies. The majority of patients (57.7%) had stage F0-F2 fibrosis. Sixty-seven (94.3%) patients completed 12 weeks of LED/SOF with RBV, three patients completed 12 or 24 weeks of LED/SOF without RBV, and one patient completed only 8 weeks of LED/SOF without RBV owing to severe allograft dysfunction. Sustained virological response was near universal in our cohort (98.5%) regardless of genotype, fibrosis stage, and regimen or treatment duration. Most commonly reported side effects were malaise and gastrointestinal upset. No patient required adjustment in immunosuppression and no episodes of rejection were documented during treatment. The combination of LED/SOF with RBV for 12 weeks or LED/SOF for 24 weeks is very effective and safe in treating OLT recipients with RHC.

    There is an increasing demand for outcomes analysis, including quality of life and financial analysis, following medical interventions and surgical procedures. We analyzed outcomes for 100 consecutive patients undergoing liver transplantation during a period of case management revision. Patient survival was calculated by Kaplan-Meier actuarial methods. The Karnofsky performance status was objectively assessed for surviving patients up to 6 years after transplantation and was evaluated by repeated measures analysis of variance and covariance. Subjective evaluation of quality of life over time was obtained using the Psychosocial Adjustment to Illness Scale. The correlations between time and scale were calculated. Financial data were accumulated from billing records. Six-month, 1-year, 2-year, and 3- through 5-year survival was 86%, 84%, 83%, and 78%, respectively. Karnofsky performance status confirmed poor functional status preoperatively with a mean of 53 +/- 2, but significantly improving to 72 +/- 2 at 3 months, 80 +/- 2 at 6 months, 90 +/- 1 at 1 year, 92 +/- 1 at 2 years, 94 +/- 1 at 3 years, 96 +/- 1 at 4 years, and 97 +/- 1 at 5 years (P <0.001). Psychosocial Adjustment to Illness Scale scores demonstrated significant improvement following transplantation overall (r = -0.33), improving most in sexual relationships (r = -0.41), and domestic environment (r = -0.35; P <0.001). Median length of stay for the first half of the patients was 19 days declining to 11 days for the second half. Median hospital charges declined from $105,000 to $90,000. Quality of life parameters assessed both by care givers (Karnofsky) and by patients (Psychosocial Adjustment to Illness Scale) improved dramatically following transplantation and over time, demonstrating that liver transplantation effectively restores a good quality of life. Outcomes can be improved while reducing length of stay and charges through modifications in case management.

    Full Text Available Introduction. While patients undergoing orthotopic liver transplantation (OLT have high cardiovascular event rates, preoperative risk stratification may not necessarily predict those susceptible patients. Troponin T (TnT may help predict patients at risk for cardiovascular complications. Methods. Consecutive patients undergoing OLT at Mayo Clinic in Florida between 1998 and 2010 who had TnT obtained within 10 days following surgery were included. Three groups were compared based on TnT level: (1 normal (TnT ≤0.01 ng/mL, (2 intermediate (TnT 0.02–0.11 ng/mL, and (3 elevated (TnT >0.11 ng/mL. Overall and cardiovascular mortality was assessed. Results. Of the 78 patients included, there was no difference in age, gender, severity of liver disease, and echocardiographic findings. Patients in the normal and intermediate TnT groups had a lower overall mortality rate (14.3% and 0%, resp. when compared with those with elevated TnT (50%; P=0.001. Patients in the elevated TnT group had a cardiovascular mortality rate of 37.5% compared with 1.4% in the other groups combined (P<0.01. The elevated TnT group had a much higher mortality rate when compared with those in the intermediate group (P<0.0001. Conclusion. TnT may accurately help risk stratify patients in the early postoperative setting to better predict cardiovascular complications.

    Psychosocial factors greatly impact the course of patients throughout the liver transplantation process. A retrospective chart review was performed of patients who underwent liver transplantation at Hadassah-Hebrew University Medical Center between 2002 and 2012. A composite psychosocial score was computed based on the patient's pre-transplant evaluation. Patients were divided into two groups based on compliance, support and insight: Optimal psychosocial score and Non-optimal psychosocial score. Post-liver transplantation survival and complication rates were evaluated. Out of 100 patients who underwent liver transplantation at the Hadassah-Hebrew University Medical Center between 2002 and 2012, 93% had a complete pre-liver transplant psychosocial evaluation in the medical record performed by professional psychologists and social workers. Post-liver transplantation survival was significantly higher in the Optimal group (85%) as compared to the Non-optimal group (56%, p = .002). Post-liver transplantation rate of renal failure was significantly lower in the Optimal group. No significant differences were observed between the groups in other post-transplant complications. A patient's psychosocial status may impact outcomes following transplantation as inferior psychosocial grades were associated with lower overall survival and increased rates of complications. Pre-liver transplant psychosocial evaluations are an important tool to help predict survival following transplantation.

    In this article is reviewed the role of Computed Tomography (CT) in thoracic complications following ortho topic liver transplantation (OLT). In a post-OLT population of 567 patients transplanted in the Italian institutions, 100 patients (17.6%) were examined with chest CT. It was reviewed data relative to the total number of examinations, clinical and/or radiographic indications, the CT technique-i.e., conventional (with (out) intravenous, i.v., contrast material) or high-resolution (HRCT). It also reviewed the radiologic patterns and their correlation with the other clinical, bronchoscopic and/or laboratory results. Of 152 chest CT examinations, 45 (29.6%) were performed because of clinical indications, 31 (20.4%) because of a radiographic abnormality, 64 (42.1%) because of clinical and radiographic abnormality, 64 (42.1%) because of clinical and radiographic indications, while in 12 cases (7.9%) the reasons were unknown; 133/152 (87.5%) examinations had been performed with conventional CT scanning (100 with i.v. contrast agent and 33 without) and 19/152 (12.5%) with HRCT. Twenty of 152 (13.2%) examinations, in 16 patients were normal; in the other 84 patients, 132/152 (86.8%) CT/HRCT studies showed 247 pathological findings (99 pleural effusions, 3 pericardial effusions, 62 cases of atelectasis, 1 pulmonary calcification, 70 suspected inflammatory parenchymal consolidations, 64 of them alveolar and 6 interstitial, 4 cases of interstitial edema and finally 8 neoplastic infiltrates). Correlated with clinical data, CT findings are very useful in detailing clinical-radiographic screening findings, despite the limitations in typifying pleural effusions, in differentiating atelectasis from inflammatory parenchymal consolidations and in assessing pneumonia etiology. Also, despite its high sensitivity (94.1%) and specificity (92.8%), CT was not accurate enough in the differential diagnosis of pneumonia. History data were necessary to characterize the histology of

    Hepatocellular carcinoma (HCC) is the third most common cause of cancer-related death worldwide. Orthotopic liver transplantation (OLT) is the best therapy of choice for early, unresectable HCC. The Hungarian Liver Transplantation Program was launched in 1995 at the Department of Transplantation and Surgery, Semmelweis University, Budapest. From that time more than 60 patients underwent OLT for hepatic tumors, which in most cases were HCC. Our clinical examination was undertaken to analyze the possible influential factors of outcomes for our series of patients who received OLT for HCC. We performed a review of all patients who underwent OLT for HCC at our department from 1996 to October 1, 2013. Disease extent was determined by preoperative computed tomography or magnetic resonance images. All explants were examined and categorized based on tumor number, size, distribution, HCC histologic grade, and vascular invasion. Patients with HCC were classified as having tumors either meeting Milan criteria, beyond Milan criteria but within UCSF criteria, or exceeding UCSF criteria. OLT was performed using standard techniques including orthotopic implantation with cross-clamp technique or with the piggyback technique. Postoperative immunosuppression included a triple drug regimen of calcineurin inhibitor (CNI), mycophenolate mofetil (MMF), and prednisone. mTOR inhibitors have been available since 2004. HCC most commonly occurs in the presence of cirrhosis as a result of longstanding chronic liver disease. Most of our patients who underwent OLT for HCC are 56 to 60 years old, and most also had underlying HCV cirrhosis. As of October 1, 2013, 21 of 49 (42.85%) patients had died after OLT for HCC. The main cause was the recurrence of the HCC in 38%, followed by sepsis in 33%, and HCV recurrence in 19%. One death each (4.7% of the total number of deaths) was caused by primary nonfunction of the graft, acute myocardial infarct, and de novo malignancy, respectively. Overall

    Full Text Available Intracardiac thrombosis (ICT and pulmonary embolism (PE during adult liver transplantation are rare but potentially lethal complications. They are often overlooked because of significant diagnostic challenges. The combination of hemodynamic compromise and transesophageal echocardiography (TEE findings allows for correct diagnosis. A large variety of putative risk factors for ICT and PE have been suggested, but these events are considered to be multifactorial. There are different proposed treatment modalities for these devastating complications. Unfortunately, in spite of growing knowledge in this area, intraoperative and postoperative mortalities remain very high. The retrospective nature of the study of these events makes the case reports extremely valuable.

    Liver transplantation has been remarkably effective in the treatment in patients with end-stage liver disease. However, disparity between solid-organ supply and increased demand is the greatest limitation, resulting in longer waiting times and increase in mortality of transplant recipients. This situation creates the need to seek alternatives to orthotopic liver transplantation.Hepatocyte transplantation or liver cell transplantation has been proposed as the best method to support patients. The procedure consists of transplanting individual cells to a recipient organ in sufficient quantity to survive and restore the function. The capacity of hepatic regeneration is the biological basis of hepatocyte transplantation. This therapeutic option is an experimental procedure in some patients with inborn errors of metabolism, fulminant hepatic failure and acute and chronic liver failure, as a bridge to orthotopic liver transplantation. In the Hospital La Fe of Valencia, we performed the first hepatocyte transplantation in Spain creating a new research work on transplant program. Copyright 2009 AEC. Published by Elsevier Espana.

    Perioperative nutritional assessment is critically important to reflect nutritional management because liver transplantation (LTx) often is undertaken in patients with poor nutritional status. The aim of this study was to evaluate nutritional status, including the non-protein respiratory quotient (npRQ), resting energy expenditure (REE), nitrogen balance, and blood biochemical parameters in patients before and after LTx. Fourteen patients undergoing LTx and 10 healthy controls were enrolled in this study. The npRQ and REE were measured using indirect calorimetry before LTx and at 2, 3, and 4 wk after the procedure. Blood biochemistry and nitrogen balance calculated by 24-h urine collection were performed concurrently with indirect calorimetric measurement; the results were compared between the two groups. Before LTx, npRQ was significantly lower and serum non-esterified fatty acid levels were significantly higher in the patients than in the controls. Furthermore, a negative nitrogen balance was observed in the patients. These, however, improved significantly at 4 wk after LTx. REE did not significantly increase compared with the preoperative values in recipients. Blood biochemistry showed gradually increasing levels of serum cholinesterase and albumin. These failed to reach to normal levels by 4 wk post-transplant. The findings revealed that improvement of nutritional metabolism after LTx may require 4 wk. Additional nutritional strategies, therefore, may be needed to minimize catabolic state during the early post-transplant period. Adequate, individualized nutritional guidance before and after LTx should be performed in these patients. Copyright © 2015 Elsevier Inc. All rights reserved.

  6. 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.

    Human liver transplantation for end-stage liver disease was first performed in 1963. Refinements in surgical technique and new immunosuppressive regimens have improved outcomes. Today, transplant patients have a 5-year survival rate of approximately 75%. Nevertheless, significant complications still occur. Ultrasonography (US), is the initial imaging modality of choice allowing bedside assessment for detection and follow-up of early and delayed graft complications, and facilitating interventional procedures. This review outlines the role of ultrasound in post-transplantation assessment.

    The supply of liver grafts for treatment of end-stage liver disease continues to fall short of ongoing demands. Currently, most liver transplants originate from donations after brain death. Enhanced utilization of the present resources is prudent to address the needs of the population. Donation after circulatory or cardiac death is a mechanism whereby the availability of organs can be expanded. Donations after circulatory death pose unique challenges given their exposure to warm ischemia. Technical principles of donations after circulatory death procurement and pertinent studies investigating patient outcomes, graft outcomes, and complications are highlighted in this review. We also review associated risk factors to suggest potential avenues to achieve improved outcomes and reduced complications. Future considerations and alternative techniques of organ preservation are discussed, which may suggest novel strategies to enhance preservation and donor expansion through the use of marginal donors. Ultimately, without effective measures to bolster organ supply, donations after circulatory death should remain a consideration; however, an understanding of inherent risks and limitations is necessary.

    Background and Aims:Hepatitis C virus (HCV) cirrhosis is the leading indication for liver transplantation in the United States and recurrent HCV following liver transplantation is a major cause of allograft loss and mortality.Liver biopsies are commonly used to identify recurrent HCV and determine the need for antiviral therapy.The introduction of directacting antiviral agents (DAAs) has changed the management of recurrent HCV infection.This study aimed to describe the role of liver biopsies in liver transplant recipients with HCV after the introduction of DAAs.Methods:A retrospective analysis was performed looking at the rate of liver biopsies post-liver transplantation for HCV.The analysis included 475 adult liver transplants for hepatitis C performed at the University of California,Los Angeles from January 1,2006 to October 1,2015.Patients were divided into two eras,pre-and post-introduction of DAAs on December 1,2013.Results:In the era before the introduction of DAAs,the percentage of patients biopsied was significantly higher compared to the era after the introduction of DAAs (56.1% vs.26.9%,p < 0.001).Conclusion:The introduction of DAAs has changed the management of liver biopsy following liver transplantation and the management of recurrent HCV.Given that DAAs are well tolerated and have high efficacy,liver biopsies are no longer routinely used to justify the use antiviral therapy following liver transplantation.

    2015-07-01

    Full Text Available Hepatitis B often progresses to decompensated liver cirrhosis requiring orthotopic liver transplantation (OLT. Although newer nucleos(tide analogues result in >90% viral and hepatitis activity control, severely decompensated patients still need OLT because of drug-resistant virus, acute exacerbation, or hepatocellular carcinoma. Acute hepatitis B is also an indication for OLT, because it can progress to fatal acute liver failure. After OLT, the hepatitis B recurrence rate is >80% without prevention, while >90% of transplant recipients are clinically controlled with combined hepatitis B immunoglobulin (HBIG and nucleos(tide analogue treatment. However, long-term HBIG administration is associated with several unresolved issues, including limited availability and extremely high cost; therefore, several treatment protocols with low-dose HBIG, combined with nucleos(tide analogues, have been investigated. Another approach is to induce self-producing anti-hepatitis B virus (HBV antibodies using an HBV envelope (HBs antigen vaccine. Patients who are not HBV carriers, such as those with acutely infected liver failure, are good candidates for vaccination. For chronic HBV carrier liver cirrhosis patients, a successful vaccine response can only be achieved in selected patients, such as those treated with experimentally reduced immunosuppression protocols. The present protocol for post-OLT HBV control and the future prospects of newer treatment strategies are reviewed.

    BACKGROUND: The clearance of propofol is very rapid, and its transformation takes place mainly in the liver. Some reports indicated extrahepatic clearance of the drug and that the lungs are the likely place where the process occurs. This study was undertaken to compare the plasma concentrations of propofol both in the pulmonary and radial arteries after constant infusion during the dissection, anhepatic and reperfusion phases of orthotopic liver transplantation (OLT) without veno-venous bypass, attempting to investigate extrahepatic clearance and to determine whether the human lungs take part in the elimination of propofol. METHODS: Fifteen patients undergoing OLT without veno-venous bypass were enrolled in the study, and propofol was infused via a forearm vein at a rate of 2 mg· kg-1·h-1. Blood samples were simultaneously collected from pulmonary and radial arteries at the end of the ifrst hepatic portal dissection (T0), at the clamping of the portal vein (T1), 30, and 60 minutes after the beginning of the anhepatic phase (T2, T3), and 30, 60, and 120 minutes after the unclamping of the new liver (T4, T5, T6). Plasma propofol concentrations were measured using a reversed-phase, high-performance liquid chromatographic method with lfuorescence detection. RESULTS: The concentrations of plasma propofol in the pulmonary and radial arteries at T2 and T3 rose signiifcantly compared with T0 and T1 (P CONCLUSIONS:Propofol is eliminated mainly by the liver, and also by extrahepatic organs. The lungs seem to be not a major site contributing to the extrahepatic metabolism of propofol in humans.

    The objective is to present the causes of late death in patients subjected to liver transplantation. A total of 209 patients were subjected to 223 liver transplantations (14 retransplantations). The computerized study protocol sheets were evaluated to determine the causes of late death (> 6 months after transplantation). Of the 209 patients, 30 had late death. Ductopenic rejection (chronic rejection) was the most common cause and it was observed in 10 patients. Time after transplantation at the moment of death of this group of patients varied from 11 to 57 months, with an average of 29 months. Seven patients died at the hospital admission of hepatic retransplantation. Other causes of late death were sepsis, lymphoproliferative disease, chronic renal insufficiency, and hepatic insufficiency. The most common cause of late death after liver transplantation is ductopenic rejection, followed by complications of retransplantation and sepsis. Death owing to ductopenic rejection may occur even many years after transplantation.

    Nonalcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease in developing countries. Approximately 25% of patients with NAFLD develop nonalcoholic steatohepatitis (NASH). NASH-related cirrhosis is now a leading listing indication for liver transplantation in the United States. Although posttransplant survival for NASH-related cirrhosis is comparable with that of other liver diseases, many patients have features of metabolic syndrome, which can contribute to a recurrence of NAFLD or NASH. This article reviews the epidemiology, pathophysiology, and treatment of de novo and recurrence of NASH after liver transplantation. Copyright © 2017 Elsevier Inc. All rights reserved.

    Candidacy for liver transplantation is determined through standardized evaluation. There are limited data on the frequency and reasons for denial of transplantation after assessment; analysis may shed light on the short-term utility of the assessment. We sought to describe the frequency and reasons for ineligibility for liver transplantation among referred adults. We studied all prospectively followed recipient candidates at a single centre who were deemed unsuitable for liver transplantation after assessment. Inclusion criteria were age 18 years and older and completion of a standard liver transplantation evaluation over a 3-year period. Patients were excluded if they had a history of prior assessment or liver transplantation within the study period. Demographic and baseline clinical data and reasons for recipient ineligibility were recorded. In all, 337 patients underwent their first liver transplantation evaluation during the study period; 166 (49.3%) fulfilled inclusion criteria. The mean age was 55.4 years, and 106 (63.9%) were men. The 3 most common reasons for denial of listing were patient too well (n = 82, 49.4%), medical comorbidities and/or need for medical optimization (n = 43, 25.9%) and need for addiction rehabilitation (n = 28, 16.9%). Ineligibility for transplantation after assessment was common, occurring in nearly half of the cohort. Most denied candidates could be identified with more discriminate screening before the resource-intensive assessment; however, the assessment likely provides unforeseen positive impacts on patient care.

    To overcome the shortage of appropriate-sized whole liver grafts for children, technical variant liver transplantation has been practiced for decades. We perform a meta-analysis to compare the survival rates and incidence of surgical complications between pediatric whole liver transplantation and technical variant liver transplantation. To identify relevant studies up to January 2014, we searched PubMed/Medline, Embase, and Cochrane library databases. The primary outcomes measured were patient and graft survival rates, and the secondary outcomes were the incidence of surgical complications. The outcomes were pooled using a fixed-effects model or random-effects model. The one-year, three-year, five-year patient survival rates and one-year, three-year graft survival rates were significantly higher in whole liver transplantation than technical variant liver transplantation (OR = 1.62, 1.90, 1.65, 1.78, and 1.62, respectively, ptechnical variant liver transplantation. Continuing efforts should be made to minimize surgical complications to improve the outcomes of technical variant liver transplantation.

    Purpose: To analyse the efficacy of intravenous spiral CT angiography (SCTA) for the evaluation before orthotopic liver transplantation (oLT) compared with DSA. Methods: Spiral CT was performed on 31 potential recipients of a liver graft in order to examine hepatic vessels, coeliac axis, splenic artery and superior mesenteric artery. The arterial vessels were reconstructed in 'Maximum Intensity Projection (MIP)' and 'Shaded Surface Display (SSD)'-technique. The axial images, MIP and SSD were compared in 25 patients with DSA with regard to the visualisation of the vascular anatomy, detectability of stenosis and vascular diameters. Results: The type of arterial liver supply could be determined via SCTA in all patients. Stenosis of the coeliac axis was seen in ten patients on the DSA, MIP and SSD and in eight patients on the axial images. Occlusion of the hepatic artery was clearly visualised in two patients on the DSA, axial images and MIP and in one patient on the SSD. There was no false positive diagnosis with SCTA. SSD was seen as the best technique to visualise the vessels without overshadowing. There were no significant differences between the diamters measured from the axial images, MIP and SSD images in transversal direction and the DSA images (p>0.05). Conclusion: SCTA is a greatly promising method for the imaging of vessels supplying the liver before oLT, and may convey more diagnostic information than DSA. (orig.) [de

    Objective: To investigate the prognosis and prognostic risk factors of hepatic artery complications after orthotopic liver transplantation (OLT) treated with the interventional techniques. Methods: The clinical data of 21 patients with hepatic artery complication after liver transplantation receiving thrombolysis, PTA, and stent placement in our institute from November 2003 to April 2007 were retrospectively analyzed. Based on the prognosis of grafts, 21 patients were divided into poor-prognosis group and non-poor-prognosis group. Fifteen variables (including biliary complication, hepatic artery restenosis, early or late artery complication, and so on) were analyzed in both groups with binary logistic regression analysis to screen out the risk factors related to prognosis of pereutaneous interventional treatment for hepatic artery complications after OLT. Results: Twenty-one patients were followed for mean 436 days, median 464 days (3-1037 days). The poor-prognosis group included 11 patients (5 cases received retransplantation, and 6 died). The mean survival time of grafts in poor-prognosis group was 191 days, and median survival time was 73 days (3-616 days). The mean survival time of grafts in non-poor-prognosis group which included 10 patients was 706 days, and median survival time was 692 days (245-1037 days). Univariate analysis showed there were significant difference in biliary complication, total bilimbin and indirect bilirubin between the two groups. The binary, logistic regression analysis showed the risk factor related to prognosis was with biliary complication before the interventional management (P=0.027, OR=22.818). Conclusion: Biliary complication before interventional management is the risk factor related to poor prognosis of patients with hepatic artery stenosis or thrombosis receiving interventional treatment.

    Tc-99m-BrIDA hepatobiliary scans are noninvasive tests for detecting biliary leaks and obstructions. However, there is low sensitivity and specificity in patients with hyperbilirubinemia. Biliary complications (BC) are the Achilles heel of orthotopic liver transplantation (OLT). We questioned whether hyperbilirubinemia in liver transplant recipients rendered HIDA scanning less dependable. HIDA findings were compared to endoscopic retrograde cholangiopancreatography, laparotomy, and clinical course. Results were categorized as follows: true positive (TP), true negative (TN), false positive (FP), false negative (FN), or nondiagnostic/inconclusive. We searched for variables associated with erroneous or nondiagnostic tests which we defined as all examinations determined to be FP, FN and/or nondiagnostic/inconclusive. Thirty-four patients underwent a HIDA scan. The sensitivity and specificity were 70 and 100%. The sensitivity of HIDA improved to 100% in patients with a total bilirubin (TB) 5 mg/dl. One FN had a TB <5 mg/dl, but was determined inconclusive due to the roux-en-Y. HIDA scans performed when the total bilirubin was <5 mg/dl had a high sensitivity and specificity for detecting biliary complications after OLT. However, when the total bilirubin exceeded 5 mg/dl, the specificity was still 100% but the numbers of nondiagnostic/inconclusive and FN exams were increased. (author)

    Bile leakage from anastomotic insufficiency is one of the commonest complications following liver transplantation. In contrast, bilothorax (cholethorax) - appearance of bile in a pleural effusion after diaphragmatic injury in patient with bile leakage and ascites, is extremely rare condition. Diaphragmatic defect can be iatrogenic as a result of surgery of the hepato-biliary system or it can be secondary to a traumatic incidence. In our case, we represent a bilothorax appeared two months after liver transplantation with bile leakage leading to bile passing from the abdominal cavity to the pleural space through a post-surgery diaphragmatic defect.

    For over 50 years patients with liver cirrhosis were considered to be at markedly increased risk of bleeding. This dogma was seemingly supported by abnormalities in standard laboratory tests (SLTs), such as the prothrombin time, that were interpreted as indicating a bleeding diathesis. However, publications from the last decade have revealed SLTs to be poor predictors of bleeding and it is now understood that stable patients with cirrhosis have a rebalanced haemostatic system and preserved thrombin generation. Viscoelastic tests (VETs), such as ROTEM® or TEG™ allow dynamic assessment of the entire coagulation process and provide a better illustration of the interactions between pro- and anticoagulants as well as platelets. Despite their documented success in reducing transfusion rates in liver transplantation more than 30 years ago, the adoption of VETs has been met with some resistance and has only recently gained significant momentum. Bleeding risk should be assessed in every patient undergoing invasive intervention and must consider markers of disease severity, underlying coagulation incompetence, anaemia and surgical factors. The recognition that bleeding in this patient cohort is predominantly linked to mechanistic factors such as portal hypertension, rather than primary coagulopathy, has led to a paradigm shift in their perioperative management. Cognizant of their detrimental effect, the use of large volumes of fresh frozen plasma to correct derangements in SLTs has given way to more refined haemostatic management with specific factor concentrates guided by VETs, coupled with measures to minimize portal venous pressure and meticulous surgical hemostasis.

  4. SINGLE-CENTER EXPERIENCE OF ABO-INCOMPATIBLE LIVER TRANSPLANTATION

    2011-01-01

    Full Text Available Since 2008 up to 2010 eight ABO-incompatible liver transplantations have been performed in our center: one of them was urgent liver transplantation to adult patient from deceased donor, other seven were transplantations of left lateral segment to children from living relative donors. Own experience, as well as world one, proves, that barrier of ABO-incompatibility can be overcome more successfully in liver transplantation, particularly in pediatric population, that in other solid organs transplantation. Good results can be achieved even with less ag- gressive immunosuppressive therapy. Recipient conditioning before operation can significantly improve results of ABO-incompatible liver transplantation, but as own experience has shown, often there’s no need to hold some special preparation of children, because their anti-ABO antibodies are very low or absent before transplantation and do not increase after it. Thereby ABO-incompatible liver transplantation is reasonable in urgent cases and in pediatric population because of the limited pull of living relative donors for children.

    The surgically-demanding mouse orthotopic liver transplant model was first described in 1991. It has proved a powerful research tool for investigation of liver biology, tissue injury, the regulation of alloimmunity and tolerance induction and the pathogenesis of specific liver diseases. Liver transplantation in mice has unique advantages over transplantation of the liver in larger species, such as the rat or pig, since the mouse genome is well-characterized and there is much greater availability of both genetically-modified animals and research reagents. Liver transplant experiments using various transgenic or gene knockout mice has provided valuable mechanistic insights into the immuno- and pathobiology of the liver and the regulation of graft rejection and tolerance over the past 25 years. The molecular pathways identified in regulation of tissue injury and promotion of liver transplant tolerance provide new potential targets for therapeutic intervention to control adverse inflammatory responses/ immune-mediated events in the hepatic environment and systemically. Conclusion: Orthotopic liver transplantation in the mouse is a valuable model for gaining improved insights into liver biology, immunopathology and allograft tolerance that may result in therapeutic innovation in liver and other diseases.

    Bone disease contributes to relevant morbidity after solid organ transplantation. Vitamin D has a crucial role for bone metabolism. Activation of vitamin D depends on the endocrine function of both, liver and kidney. Our study assessed key markers of bone metabolism at time of transplantation and 6 months after transplantation among 70 kidney and 70 liver recipients. In 70 kidney recipients 25-OH vitamin D levels did not differ significantly between peri-transplant (median 32.5nmol/l) and 6 months post-transplant (median 41.9nmol/l; P = 0.272). Six months post-transplant median 1, 25-(OH)2 vitamin D levels increased by >300% (from 9.1 to 36.5ng/l; Ptransplantation and of intact parathyroid hormone 6 months post-transplant. Among 70 liver recipients, 25-OH vitamin D, 1, 25-(OH)2 vitamin D and intact parathyroid hormone levels were not significantly altered between peri-transplant and 6 months post-transplant. Contrary to kidney recipients, median CTx increased by 60.0% (from 0.45 to 0.72 ng/ml; P = 0.002) and P1NP by 49.3% (from 84.0 to 125.4ng/ml; P = 0.001) in the longitudinal course. Assessed biomarkers didn't differ between liver recipients with and without fractures. To conclude, the assessed panel of biomarkers proved highly dynamic after liver as well as kidney transplantation in the early post-transplant period. After kidney transplantation a significant gain in 1, 25-(OH)2 vitamin D combined with a decline in iPTH, CTx and P1NP, whereas after liver transplantation an increase in CTx and P1NP were characteristic.

    Congenital factor VII (FVII) deficiency is the commonest type of the rare bleeding disorders. Very few cases of congenital FVII deficiency developed inhibitor and liver transplant is considered as definitive treatment. In the literature, twelve patients with congenital FVII deficiency developed inhibitors. Two had spontaneous resolution of inhibitors and one did not respond to high dose recombinant factor VIIa (rFVIIa) and died. Regarding liver transplant in congenital FVII patients, seven patients underwent liver transplant with good prognosis. We report a 5-year-old girl with confirmed severe congenital FVII deficiency since neonatal period. She suffered from recurrent intracranial bleeding despite rFVIIa replacement. After auxiliary liver transplant at the age of 4, she continued to show persistent deranged clotting profile and was found to have inhibitor towards FVII. Interestingly, she was still responsive to rFVIIa replacement. © 2016 John Wiley & Sons Ltd.

    Liver transplantation in patients with liver cirrhosis, portal vein thrombosis, and cavernous transformation of the portal vein, is a complex procedure with high possibility of liver graft dysfunction. It is performed in 2-19% of all liver transplants, and has a significantly high mortality rate in the post-operative period. Other procedures to maintain portal perfusion have been described, however there are no reports of liver graft perfusion using right gastroepiploic vein. A 20 year-old female diagnosed with cryptogenic cirrhosis, with a Child-Pugh score of 7 points (class "B"), and MELD score of 14 points, with thrombosis and cavernous transformation of the portal vein, severe portal hypertension, splenomegaly, a history of upper gastrointestinal bleeding due to oesophageal varices, and left renal agenesis. The preoperative evaluation for liver transplantation was completed, and the right gastroepiploic vein of 1-cm diameter was observed draining to the infrahepatic inferior vena cava and right suprarenal vein. An orthotopic liver transplantation was performed from a non-living donor (deceased on January 30, 2005) using the Piggy-Back technique. Portal vein perfusion was maintained using the right gastroepiploic vein, and the outcome was satisfactory. The patient was discharged 13 days after surgery. Liver transplantation was performed satisfactorily, obtaining an acceptable outcome. In this case, the portal perfusion had adequate blood flow through the right gastroepiploic vein.

    Osteoporosis is common in liver transplant recipients as a result of both iatrogenic factors and preexisting hepatic osteodystrophy. To assess the prevalences of osteoporosis and fractures and to identify risk factors for these two abnormalities in patients awaiting liver transplantation for end-stage liver disease. Between January 2006 and December 2007, patients on a liver transplant waiting list underwent a routine evaluation comprising the identification of risk factors for osteoporosis, radiographs of the spine, bone mineral density measurements (BMD), and laboratory tests (phosphate and calcium levels, hormone assays, liver function tests, and bone turnover markers). We studied 99 patients (70 males and 20 females; mean age, 55 ± 8 years) including 75% with alcohol-induced cirrhosis with or without hepatocarcinoma. Among them, 36% had radiographic vertebral fractures, 38% had osteoporosis, 35% had osteopenia, and 88% had vitamin D insufficiency or deficiency (25(OH)vitamin D3bone resorption markers correlated negatively with BMD at the spine and hip. The Model for End-Stage Liver Disease score correlated negatively with hip BMD. Our findings suggest high prevalences of low BMD values and vertebral fractures among patients awaiting liver transplantation. Bone status should be evaluated routinely in candidates to liver transplantation. Copyright © 2011 Société française de rhumatologie. Published by Elsevier SAS. All rights reserved.

    The aim of this study was to evaluate the incidence, radiographic appearance, time of onset, outcome and risk factors of non-infectious and infectious pulmonary complications following liver transplantation. Chest X-ray features of 300 consecutive patients who had undergone 333 liver transplants over an 11-year period were analysed: the type of pulmonary complication, the infecting pathogens and the mean time of their occurrence are described. The main risk factors for lung infections were quantified through univariate and multivariate statistical analysis. Non-infectious pulmonary abnormalities (atelectasis and/or pleural effusion: 86.7%) and pulmonary oedema (44.7%) appeared during the first postoperative week. Infectious pneumonia was observed in 13.7%, with a mortality of 36.6%. Bacterial and viral pneumonia made up the bulk of infections (63.4 and 29.3%, respectively) followed by fungal infiltrates (24.4%). A fairly good correlation between radiological chest X-ray pattern, time of onset and the cultured microorganisms has been observed in all cases. In multivariate analysis, persistent non-infectious abnormalities and pulmonary oedema were identified as the major independent predictors of posttransplant pneumonia, followed by prolonged assisted mechanical ventilation and traditional caval anastomosis. A ''pneumonia-risk score'' was calculated: low-risk score ( 3.30) population. The ''pneumonia-risk score'' identifies a specific group of patients in whom closer radiographic monitoring is recommended. In addition, a highly significant correlation (p<0.001) was observed between pneumonia-risk score and the expected survival, thus confirming pulmonary infections as a major cause of death in OLT recipients.

  14. Current concepts on cytomegalovirus infection after liver transplantation.

    Lee, Sang-Oh; Razonable, Raymund R

    2010-09-27

    Cytomegalovirus (CMV) is the most common viral pathogen that negatively impacts on the outcome of liver transplantation. CMV cause febrile illness often accompanied by bone marrow suppression, and in some cases, invades tissues including the transplanted allograft. In addition, CMV has been significantly associated with an increased predisposition to allograft rejection, accelerated hepatitis C recurrence, and other opportunistic infections, as well as reduced overall patient and allograft survival. To negate the adverse effects of CMV on outcome, its prevention, whether through antiviral prophylaxis or preemptive therapy, is regarded as an essential component to the medical management of liver transplant patients. Two recent guidelines have suggested that antiviral prophylaxis or preemptive therapy are similarly effective in preventing CMV disease in modest-risk CMV-seropositive liver transplant recipients, while antiviral prophylaxis is the preferred strategy over preemptive therapy for the prevention of CMV disease in high-risk recipients [CMV-seronegative recipients of liver allografts from CMV-seropositive donors (D+/R-)]. However, antiviral prophylaxis has only delayed the onset of CMV disease in many CMV D+/R- liver transplant recipients, and at least in one study, such occurrence of late-onset primary CMV disease was significantly associated with increased mortality after liver transplantation. Therefore, optimized strategies for prevention are needed, and aggressive treatment of CMV infection and disease should be pursued. The standard treatment of CMV disease consists of intravenous ganciclovir or oral valganciclovir, and if feasible, one should also reduce the degree of immunosuppression. In one recent controlled clinical trial, valganciclovir was found to be as effective and safe as intravenous ganciclovir for the treatment of mild to moderate CMV disease in solid organ (including liver) transplant recipients. In this article, the authors review the

    The first clinical orthotopic liver transplantation in Brazil was performed on August 5, 1968. The patient was awake after surgery and died on the seventh postoperative day due to subdural hematoma, bronchopneumonia, renal failure, and graft rejection. The report of this case is important to understand the evolution of clinical liver transplantation in Brazil, where this procedure is now routinely carried out in many medical centers.

    The portal vein remains the preferred site for pancreatic islet transplantation due to its easy access and low morbidity. However, despite great progress in isolation and transplantation protocols over the past few years, it is still associated with the early loss of some 50-70% of transplanted islets. The complex liver microenvironment itself presumably plays an important role in this loss. The present review focuses on the specifics of the liver microenvironment, notably the localized hepatic ischemia/reperfusion injury following transplantation, the low oxygenation of the portal vein, the instant blood-mediated inflammatory reaction, the endogenous liver immune system, and the gut-liver axis, and how they can each have an impact on the transplanted islets. It identifies the potential, or already applied, clinical interventions for improving intraportal islet survival, and pinpoints those promising areas still lacking preclinical research. Future interventions on clinical intraportal islet transplantation need to take into account the global context of the liver microenvironment, with multi-point interventions being most likely to improve early islet survival and engraftment. © 2017 The Authors.

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.

    In rats suffering from hepatic enzymatic deficiency transplanted hepatocytes could be evidenced scintigraphically in liver, spleen and granulomas. In pigs, however, it is very difficult to demonstrate transplanted hepatocytes by scintiscanning because of the thickness of the tissues and the high background radiation in large animals

    One of the most important problems after solid organ transplantation including liver, remains infections. Multiple risk factors play a role among which the most important are: general patients health before transplantation, prolong operative time, graft function and type of immunosuppression. The most important problems with bacterial, fungal and viral infections was described as well as treatment and profilaxis.

    Full Text Available Aim. Single-center analysis of everolimus treatment after liver transplantation. Materials and methods. 23 patients having received Certican after OLT in RSCRST were observed in period from 6 months to 5 years; comparison group consisted of 50 patients who received immunosuppressive scheme with tacrolimus. Conversion to everolimus was performed in the period from 1 month after OLT after discharge and at later time according to the indications: hepatocellular cancer, cumulative CNI nephrotoxicity, the development of malignancies, and intolerance to CNI. The concentrations of CNI and everolimus in the blood (target concentration of tacrolimus 1.5–2 ng/ml, everolimus 3–8 ng/ml were monitored. Glomerular filtration rate (GFR was determined using the CKD-EPI equation. Adverse events of everolimus were evaluated. Results. The immunosuppressive scheme with everolimus is presented; adverse events with dose-dependent hypercholesterolemia (34.7% as the main; the average level of blood cholesterol was not significantly different from that in the control group, 5.6 ± 0.9 vs 5.1 ± 1.4 mmol/l (Z = 1.3, p = 0.17. Renal function was stable throughout the observation period (35 ± 16 months. GFR (CKD-EPI before conversion was 75.8 ± 17.5 ml/min. 6 patients treated with Certican for 5 years had final GFR 96.6 ± 5.1 ml/min. GFR in the group of Certican at 12 months post conversion was 87.5 ± 16.3 ml/min vs 94.2 ± 16.8 ml/min (p = 0.08 in the control group. We revealed metastases to the liver and lungs in 5 patients from 13 patients with HCC, survival rate in this group depended on the compliance with the Milan criteria (Z = 2.4, p = 0.02. Conclusion. Everolimus allows maintaining of a stable renal function to prevent progression of renal failure; conversion should be initiated as early as possible. Combination of everolimus with reduced dose of CNI is optimal. Despite the fact that side effects are developing in most patients, adequate monitoring of

    Full Text Available The animal model of the whole-size and reduced-size liver transplantation in both rat and mouse has been successfully established. Because of the difficulties and complexities in microsurgical technology, the animal model of dual liver transplantation was still not established for twelve years since the first human dual liver transplantation has been made a success. There is an essential need to establish this animal model to lay a basic foundation for clinical practice. To study the physiological and histopathological changes of dual liver transplantation, "Y" type vein from the cross part between vena cava and two iliac of donor and "Y' type prosthesis were employed to recanalize portal vein and the bile duct between dual liver grafts and recipient. The dual right upper lobes about 45-50% of the recipient liver volume were taken as donor, one was orthotopically implanted at its original position, the other was rotated 180° sagitally and heterotopically positioned in the left upper quadrant. Microcirculation parameters, liver function, immunohistochemistry and survival were analyzed to evaluate the function of dual liver grafts. No significant difference in the hepatic microcirculatory flow was found between two grafts in the first 90 minutes after reperfusion. Light and electronic microscope showed the liver architecture was maintained without obvious features of cellular destruction and the continuity of the endothelium was preserved. Only 3 heterotopically positioned graft appeared patchy desquamation of endothelial cell, mitochondrial swelling and hepatocytes cytoplasmic vacuolization. Immunohistochemistry revealed there is no difference in hepatocyte activity and the ability of endothelia to contract and relax after reperfusion between dual grafts. Dual grafts made a rapid amelioration of liver function after reperfusion. 7 rats survived more than 7 days with survival rate of 58.3.%. Using "Y" type vein and bile duct prosthesis, we

    Many children with chronic liver disease require a liver transplant. These patients are prone to various infections, including Epstein-Barr virus infection. This study sought to measure the Epstein-Barr viral load by polymerase chain reaction before a liver transplant. This cross-sectional study was done at the Shiraz University of Medical Sciences, Shiraz, Iran, in 2011. All patients were aged younger than 18 years with chronic liver disease and were candidates for a liver transplant at the Shiraz Nemazee Hospital Organ Transplant Center. They had been investigated regarding their demographic characteristics, underlying disease, laboratory findings, and Epstein-Barr viral load by real-time TaqMan polymerase chain reaction. Ninety-eight patients were studied and the mean age was 6.5 ± 5.9 years. Cryptogenic cirrhosis was the most-prevalent reason for liver transplant, and the death rate before a transplant was 15%. Among the study subjects, 6 had measurable Epstein-Barr viral load by polymerase chain reaction before the transplant, and 4 of them had considerably higher Epstein-Barr viral loads (more than 1000 copies/mL). With respect to the close prevalence of posttransplant lymphoproliferative disease (6%) and the high Epstein-Barr viral load in the patients before a transplant (4%), high pretransplant Epstein-Barr viral load can be considered a risk factor for posttransplant lymphoproliferative disorder.

  4. Spontaneous Clearance of Hepatitis C after Liver and Renal Transplantation

    Full Text Available Spontaneous clearance of hepatitis C virus (HCV is rare in immunocompromised patients, such as those who have undergone organ transplantation. It has been recognized that patients receiving liver transplantation for HCV-related disease have decreased graft and patient survival compared with those transplanted for other etiologies. There is a growing trend toward treating HCV recurrence aggressively after liver transplantation. For other organ transplant recipients with concurrent HCV, treatment is not often an option, given the high rates of graft rejection and loss secondary to interferon and its immunomodulatory effects. Although spontaneous clearance of HCV has been reported in recipients of solitary liver and renal transplants, a common factor arising in these cases has been previous exposure to interferon. To date, no reports of spontaneous clearance of HCV RNA have been reported in a multiorgan transplant recipient. A case of spontaneous clearance of HCV RNA in an immunocompromised patient, within five months of simultaneous liver and kidney retransplantation is described. Importantly, this patient had no previous exposure to interferon.

    Objectives To report the clinical experiences of srmultaneous hepatorenal transplantation. Methods We performed simultaneous hepatorenal transplantation in one patient with liver cirrhosis of hepatitis B and uremia of chronic nephritis on February 1,1999 and one patient with liver cirrhosis of hepatitis B complicated by hepatorenal syndrome on March 12, 1999.The donors were heart arrest cases. Rapid multiple organ harvesting techniques and UW solution infusion in situ were used. Liver and kidney transplantation were orthotopic and ordinary methods, respectively. Immunosuppressive drugs consisted of cyclosporine, Cellcept, ALG and sortstso steroids. Lamividine was used os day 50 and day 40 postoparation, respectively. Results Both transplanted organs rapidly achieved normal function postoperation and the patients recovered well but suffered mild kidney rejection day 110 postopemtion in No 1 patient. In No 2 patient, acute renal function failure, mental symptoms, muscle spasm,cerebral artery thrombosis, inhalation poeumonia and chronic liver graft rejection ensured sequentially but were controlled.The patients have survived for more than nine and eight months, respectively, with normal life quality. Conclusions Combined hepatorenal transplant is a radical treatment method for liver and kidney function failure and requires more comprehensive techniques than isolated single organ transplantation.Preventing the recurrence of hepatitis B by oral lamividine may be a kdy to long-term survival.

    Successful liver transplantation not only treats the underlying liver disease but also restores libido and fertility in female recipients. Although reports of successful pregnancy after liver transplantation continue to increase, these pregnancies are considered of high-risk because they are associated with increase maternofetal morbidity. A MEDLINE search (1978-2007) was conducted using the terms 'liver transplantation', 'pregnancy', 'immunosuppressive agents', 'sexual function'. Reviews, retrospective series, long-term clinical follow-up of case series and original articles containing basic scientific observations were included. Although no formal guidelines have been established there are some 'golden rules' to improve the probability of favorable maternal and fetal outcome. Most transplant centers recommend to delay pregnancy for at least 1-year after transplantation. The recipient should be on a stable immunosuppression regimen, with good graft function and no evidence of renal dysfunction or uncontrolled arterial hypertension. Considering the increased incidence of prematurity, low birth weight, hypertension and preeclampsia reported during pregnancy post-LT, these high-risk patients should be managed by a multidisciplinary team, including an obstetrician specialized in high-risk pregnancies. Carefully monitoring of immunosuppressive drugs serum level is prudent to avoid graft rejection episodes and drugs with teratogenic potential should be discontinued. Breastfeeding is usually not recommended. Successful pregnancies are the rule after liver transplantation. A carefully monitoring by an experience multidisciplinary team increases the chances of favorable maternofetal outcome.

    Transarterial chemoembolization (TACE) is established as bridging therapy of HCC listed for transplantation (LT). CT-guided brachytherapy (CTB) has not been evaluated as a bridging concept. We compared CTB and TACE for bridging before LT in HCC patients. Twelve patients with HCC received LT after CTB (minimal tumour dose, 15-20 Gy). Patients were matched (CTB:TACE, 1:2) by sex, age, number and size of lesions, and underlying liver disease with patients who received TACE before transplantation. Study endpoints were extent of necrosis at histopathology and recurrence rate after OLT. There were no significant differences between the CTB and TACE groups regarding Child-Pugh category (p = 0.732), AFP (0.765), time on waiting list (p = 0.659), number (p = 0.698) and size (p = 0.853) of HCC lesions, fulfilment of Milan-criteria (p = 0.638), or previous liver-specific treatments. CTB achieved higher tumour necrosis rates than TACE (p = 0.018). The 1- and 3-year recurrence rate in the CTB group was 10 and 10 % vs. TACE, 14 and 30 % (p = 0.292). Our data show comparable or even better response and post-LT recurrence rates of CTB compared to TACE for treating HCC in patients prior to LT. CTB should be further evaluated as an alternative bridging modality, especially for patients not suited for TACE. (orig.)

    Although alcoholic liver disease (ALD) is regarded as a common indication for liver transplantation (LT), debatable issues exist on the requirement for preceding alcoholic abstinence, appropriate indication criteria, predictive factors for alcoholic recidivism, and outcomes following living-donor LT. In most institutions, an abstinence period of six months before LT has been adopted as a mandatory selection criterion. Data indicating that pre-transplant abstinence is an associated predictive factor for alcoholic recidivism supports the reasoning behind this. However, conclusive evidence about the benefit of adopting an abstinence period is yet to be established. On the other hand, a limited number of reports available on living-donor LT experiences for ALD patients suggest that organ donations from relatives have no suppressive effect on alcoholic recidivism. Prevention of alcoholic recidivism has proved to be the most important treatment after LT based on the resultant inferior long-term outcome of patients. Further evaluations are still needed to establish strategies before and after LT for ALD.

    To receive a liver transplant, patients must first be placed on a waiting list-a decision made at most transplant centers by a multidisciplinary committee. The function of these committees has never been studied. To describe decision making in liver transplant committees and identify opportunities for process improvement. Observational multicenter study. 4 liver transplant centers in the United States. 68 members of liver transplant committees across the 4 centers. 63 meetings were observed, and 50 committee members were interviewed. Recorded transcripts and field notes were analyzed by using standard qualitative sociologic methods. Although the structure of the meetings varied by center, the process was uniform and primarily involved inductive reasoning to review possible reasons for patient exclusion. Patients were excluded if they were too well, too sick (in the setting of advanced liver disease), or too old or had nonhepatic comorbid conditions, substance abuse problems, or other psychosocial barriers. Dominant themes in the discussions included member angst over deciding who lived or died, a high correlation between psychosocial barriers to transplantation and the patient's socioeconomic status, and the influence of external forces on decision making. Unwritten center policies and confusion regarding advocacy versus stewardship roles were consistently identified as barriers to effective group decision making. The use of qualitative methods provides broad understanding but limits specific inferences. The 4 centers may not reflect the practices of every transplant center nationwide. The difficult decisions made by liver transplant committees are reasonably consistent and well-intentioned, but the process might be improved by having more explicit written policies and clarifying roles. This may inform resource allocation in other areas of medicine. The Greenwall Foundation and the National Institutes of Health.

    2015-07-01

    This review aims to outline the delivery of liver transplant services in the UK. Liver transplantation in the UK is based on seven designated transplant units serving a population of just over 60 million people. Nearly 900 liver transplants were done in 2013/2014. Potential deceased donors are identified and referred to centrally employed specialist nurses for obtaining family consent and for donor characterisation. Organs are retrieved by a National Organ Retrieval Service, based on seven abdominal and six cardiothoracic retrieval teams providing a 24/7 service which has shown to be capable of retrieving organs from up to ten donors a day. Donated organs are allocated first nationally to those who qualify for super-urgent listing. The next priority is for splitting livers, and if there is no suitable recipient or the liver is not suitable for splitting, then livers are offered first to the local centre; each centre has a designated donor zone, adjusted annually to ensure equity between the number of patients listed and the number of donors. The allocation scheme is being reviewed, and national schemes based on need, utility and benefit are being assessed. Outcomes are monitored by National Health Service Blood and Transplant (NHSBT), and if there is a possibility of adverse deviation, then further inquiries are made. Outcomes, both from listing and from transplantation, are published by the centre on the NHSBT website ( www.odt.nhs.uk ). NHSBT works closely with stakeholders primarily through the advisory groups with clinicians, patients, lay members and professional societies and aims to provide openness and transparency. The system for organ donation and delivery of liver transplant in the UK has developed and is now providing an effective and efficient service, but there remains room for improvement.

    The aim was to evaluate the role of procalcitonin (PCT) and (1-3)-β-D-glucan (BG) tests for early detection or exclusion of central venous catheter-related bloodstream infections (CRBSI) in patients after orthotopic liver transplantation (OLT). Fifty-five patients with clinically suspected CRBSI were assessed after OLT in this prospective study. On the day of clinical suspicion of CRBSI, blood samples were obtained from central venous catheters and a peripheral vein for blood cultures and from a peripheral vein for PCT and BG tests. Plasma PCT and BG values were measured by using an immunoluminometric assay and Fungitell BG assay, respectively. No prisoners or organs from prisoners were used in this study. Twenty-five patients (45%) were diagnosed with CRBIS. Among them, 13 (52%) displayed gram-positive bacteriemia, 11 (44%) gram-negative bacteriemia, and 1 (4%) fungemia. The PCT values were higher in CRBSI than in non-CRBSI patients (P = .003). CRBSI patients did not show significant increases in plasma BG values compared with non-CRBSI subjects (P = .051). PCT and BG area under receiver operating characteristic curves were 0.840 and 0.486, respectively. Sensitivity, specificity, and positive and negative predictive values of a PCT of ≥ 3.1 ng/mL for the diagnosis of CRBSI were 0.72, 0.87, 0.82, and 0.79, respectively. The figures for a BG of ≥ 83 pg/mL were 0.32, 0.90, 0.73, and 0.61, respectively. Among the 24 patients with bacteria infections, PCT was higher in patients with gram-negative than those with gram-positive bacterial infections (P = .022). We concluded that the PCT assay may be a useful rapid diagnostic adjunct for the diagnosis of suspected CRBSI in OLT patients. Copyright © 2011 Elsevier Inc. All rights reserved.

    Objective: To evaluate multislice CT in the diagnosis of biliary complications after liver transplantation. Methods: Eighty-three consecutive patients who had undergone orthotopic liver transplantation (OLT) presented with clinical or biochemical signs of biliary complications and underwent contrast-enhancement CT examination. Three experienced radiologists, who were blinded to patient's clinical data, assessed CT images for the detection of biliary complications in consensus. Diagnostic confirmation of biliary complications was obtained with direct cholangiography in 69 patients, histologic study in 11 patients and hepaticojejunostomy in 3 patients. The sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of CT for the detection of biliary complications were calculated. In addition, CT features of anastomotic biliary stricture (ABS) were compared with those of non-anastomotic biliary stricture (NABS) using χ 2 test. Results: A total of 62 biliary complications (74.7%) was eventually confirmed in the 83 patients, including ABS in 32 patients, NABS in 21 patients, biliary duct stones in 16 patients (of which 12 patients with biliary stricture) , anastomotic bile leakage in 5 patients, biloma in 4 patients with biliary stricture, and biliogenic abscess in 2 patients with biliary stricture. The sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of CT for the detection of biliary stricture were 90.6%, 86.7%, 89.2%, 92.3% and 83.9%, respectively. Other biliary complications, including biliary duct stones (16 cases), anastomotic bile leak (5 cases), biloma (4 cases), and biliogenic abscess (2 cases), were correctly diagnosed by CT; there was no false-positive or false-negative result. The incidence of irregular dilatation of bile duct was 71.4% (15/21), which was significantly higher in NABS cases than in ABS of 25.0% (8/32, P<0.01); whereas the incidence of extrahepatic biliary dilatation

    The first case of domino liver transplantation from a brain-dead donor in Japan is described. A 49-year-old man with familial amyloidotic polyneuropathy received a cadaver liver, and his native liver was transplanted into a 53-year-old man with polycystic liver and kidney disease. The cadaveric liver allograft was transplanted by the conventional technique. The graft taken from the first recipient had four outflow orifices (the left, middle, and right hepatic veins, and upper vena cava), for which a single orifice was created at the back table. This graft was transplanted in piggy-back fashion. The first recipient developed acute rejection on day 13 and hepatic artery stenosis on day 36. These were treated by steroid recycle therapy and percutaneous transarterial angioplasty. He was discharged on day 57 with normal liver function. The second recipient underwent re-operation for bleeding from the right adrenal gland and left thoracic cavity. He was diagnosed with acute rejection on day 7, which was treated by steroid pulse therapy. He was discharged uneventfully on day 39 with normal liver function.

    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

    Despite advances in patient and graft management, biliary complications (BC) still represent a challenge both in the early and delayed period after orthotopic liver transplantation (OLT). Because of unspecific clinical presentation, imaging is often mandatory in order to diagnose BC. Among imaging modalities, magnetic resonance cholangiography (MRC) has gained widespread acceptance as a tool to represent the reconstructed biliary tree noninvasively, using both the conventional technique (based on heavily T2-weighted sequences) and contrast-enhanced MRC (based on the acquisition of T1-weighted sequences after the administration of hepatobiliary contrast agents). On this basis, MRC is generally indicated to: (1) avoid unnecessary procedures of direct cholangiography in patients with a negative examination and/or identify alternative complications; and (2) provide a road map for interventional procedures or surgery. As illustrated in the review, MRC is accurate in the diagnosis of different types of biliary complications, including anastomotic strictures, non-anastomotic strictures, leakage and stones.

Improved surgical and medical management has led to significant improvements in post-transplant survival rates with a 1 year and 5 year patient survival of 87% and 73%, respectively. A high mortality rate due to infections during the first post-transplant year persists. Invasive candidiasis is recognized as a significant problem associated with high morbidity and mortality. Recent surveillance data has helped to understand the changes in the epidemiology and the evolving trends in the use of antifungal agents for prophylaxis and treatment combined with the challenges of managing these invasive fungal infections, which has led the transplant community to explore the best management strategies. The emergence of resistant fungi and excess costs in managing these invasive fungal infections has added to the complexities of management. In this context, current perspectives in the management of Candida infections in liver transplant recipients will be reviewed. Keywords: Candida infections, management, liver transplant

    New Zealand is a geographically isolated country with 4.55 million inhabitants. It has endemic hepatitis B (HBV) infection that is especially evident in Maori and Pacific Island communities and impacts indications for liver transplantation. The country has a socialised medical system that allows for full coverage of the assessment for, and completion of liver transplants in suitable recipients. Between February 1998 and December 2014, the New Zealand Liver Transplant Unit (NZLTU) had performed 595 liver transplants in 568 patients, indicating a crude re-transplant rate of 4.8%. Overall 1, 5, and 10 year patient survival rates for all adult (96%, 89%, and 81%, respectively) and pediatric (93%, 92%, and 92%, respectively) recipients compare very favourably with international outcomes from Europe and the United States. Eligibility criteria could be modestly expanded if deceased donor rates improved from the current level of around 10 per million of population per year. This somewhat meagre supply of deceased donor organs, along with significant waiting list attrition, has necessitated the use of living donors, which have been used in more than 50 recipients to date. Despite these limitations, the NZLTU has contributed to improvements in the outcome of transplantation for HBV and hepatitis C through the development of effective antiviral prophylaxis regimes. Furthermore, innovative changes have been made to the manner in which pediatric patients are transitioned to the adult service.

    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

    To analyze the nutritional status of pediatric patients after orthotopic liver transplantation and the relationship with short-term clinical outcome. Anthropometric evaluations of 60 children and adolescents after orthotopic liver transplantation, during the first 24 hours in a tertiary pediatric intensive care unit. Nutritional status was determined from the Z score for the following indices: weight/age height/age or length/age, weight/height or weight/length, body mass index/age, arm circumference/age and triceps skinfold/age. The severity of liver disease was evaluated using one of the two models which was adequated to the patients' age: 1. Pediatric End-stage Liver Disease, 2. Model for End-Stage Liver Disease. We found 50.0% undernutrition by height/age; 27.3% by weight/age; 11.1% by weight/height or weight/ length; 10.0% by body mass index/age; 61.6% by arm circumference/age and 51.0% by triceps skinfold/age. There was no correlation between nutritional status and Pediatric End-stage Liver Disease or mortality. We found a negative correlation between arm circumference/age and length of hospitalization. Children with chronic liver diseases experience a significant degree of undernutrition, which makes nutritional support an important aspect of therapy. Despite the difficulties in assessment, anthropometric evaluation of the upper limbs is useful to evaluate nutritional status of children before or after liver transplantation.

    Cytomegalovirus(CMV)is a common viral pathogen that influences the outcome of liver transplantation.In addition to the direct effects of CMV syndrome and tissue-invasive diseases,CMV is associated with an increased predisposition to acute and chronic allograft rejection,accelerated hepatitis C recurrence,and other opportunistic infections,as well as reduced overall patient and allograft survival.Risk factors for CMV disease are often interrelated,and include CMV D+/R-serostatus,acute rejection,female gender,age,use of high-dose mycophenolate mofetil and prednisone,and the overall state of immunity.In addition to the role of CHV-specific CD4+ and CD8+ T lymphocytes,there are data to suggest that functionality of the innate immune system contributes to CMV disease pathogenesis.In one study,liver transplant recipients with a specific polymorphism in innate immune molecules known as Toll-like receptors were more likely to develop higher Ievels of CMV replication and clinical disease.Because of the direct and indirect adverse effects of CMV disease,its prevention,whether through antiviral prophylaxis or preemptive therapy,is an essential component in improving the outcome of liver transplantation.In the majority of transplant centers,antiviral prophylaxis is the preferred strategy over preemptive therapy for the prevention of CMV disease in CMV-seronegative recipients of liver allografts from CMV-seropositive donors(D+/R-).However,the major drawback of antiviral prophylaxis is the occurrence of delayed-onset primary CMV disease.In several prospective and retrospective studies,the incidence of delayed-onset primary CMV disease ranged from 16% to 47% of CMV D+/R-liver transplant recipients.Current data suggests that delayed-onset CMV disease is associated with increased mortality after liver transplantation.Therefore,optimized strategies for prevention and novel drugs with unique modes of action are needed.Currently,a randomized controlled clinical trial is being

    Cystic duct remnant mucocele is an extremely rare complication of liver transplantation in children. Surgical correction is usually required for cystic duct remnant mucocele when it causes biliary obstruction. We describe a 14-month-old liver transplant recipient who presented with biliary obstruction 1 month after orthotopic liver transplantation with an end-to-end choledochocholedocal biliary anastomosis for hepatoblastoma. US, CT and cholangiography findings were consistent with mucocele of the allograft cystic duct remnant. Surgery was not needed in our patient because the mucocele and biliary obstruction had resolved on repeat imaging most likely due to guidewire manipulation during cholangiography, resulting in opening of the cystic duct remnant orifice and drainage into the common duct.

    Full Text Available Biliary complications have great importance for liver transplant recipients because of affecting long-term prognosis. In rare situations, an internal hernia of the Roux-en-Y loop cause graft injury. A 42-year-old woman with a history of living donor liver transplantation 6 years ago presented with prolonged graft injury during the past 6 months. She suddenly developed ileus of the small bowel with internal hernia through the defect of the mesentery around the Roux-en-Y limb of the hepaticojejunostomy. Emergent surgery was performed to reduce the hernia and volvulus; also the mesenteric rent was closed with interrupted suture of silk. Internal hernia of the small bowel after liver transplantation is rare but causes graft injury due to associated biliary complications and rapid deterioration of patient’s condition.

    Manual tracing of the right and left liver lobes from computed tomography (CT) images for graft volumetry in preoperative surgery planning of living donor liver transplantation (LDLT) is common at most medical centers. This study aims to develop an automatic system with advanced image processing algorithms and user-friendly interfaces for liver graft volumetry and evaluate its accuracy and efficiency in comparison with a manual tracing method. The proposed system provides a sequential procedure consisting of (1) liver segmentation, (2) blood vessel segmentation, and (3) virtual liver resection for liver graft volumetry. Automatic segmentation algorithms using histogram analysis, hybrid level-set methods, and a customized region growing method were developed. User-friendly interfaces such as sequential and hierarchical user menus, context-sensitive on-screen hotkey menus, and real-time sound and visual feedback were implemented. Blood vessels were excluded from the liver for accurate liver graft volumetry. A large sphere-based interactive method was developed for dividing the liver into left and right lobes with a customized cutting plane. The proposed system was evaluated using 50 CT datasets in terms of graft weight estimation accuracy and task completion time through comparison to the manual tracing method. The accuracy of liver graft weight estimation was assessed by absolute difference (AD) and percentage of AD (%AD) between preoperatively estimated graft weight and intraoperatively measured graft weight. Intra- and inter-observer agreements of liver graft weight estimation were assessed by intraclass correlation coefficients (ICCs) using ten cases randomly selected. The proposed system showed significantly higher accuracy and efficiency in liver graft weight estimation (AD = 21.0 ± 18.4 g; %AD = 3.1% ± 2.8%; percentage of %AD > 10% = none; task completion time = 7.3 ± 1.4 min) than the manual tracing method (AD = 70

    Full Text Available ABSTRACT BACKGROUND: The Amazon region is one of the main endemic areas of hepatitis delta in the world and the only one related to the presence of genotype 3 of the delta virus. OBJECTIVE: To analyze the profile, mortality and survival of cirrhotic patients submitted to liver transplantation for chronic hepatitis delta virus and compare with those transplanted by hepatitis B virus monoinfection. METHODS: Retrospective, observational and descriptive study. From May 2002 to December 2011, 629 liver transplants were performed at the Walter Cantídio University Hospital, of which 29 patients were transplanted due to cirrhosis caused by chronic delta virus infection and 40 by hepatitis B chronic monoinfection. The variables analyzed were: age, sex, MELD score, Child-Pugh score, upper gastrointestinal bleeding and hepatocellular carcinoma occurrence before the transplantation, perioperative platelet count, mortality and survival. RESULTS: The Delta Group was younger and all came from the Brazilian Amazon Region. Group B presented a higher proportion of male patients (92.5% compared to Group D (58.6%. The occurrence of upper gastrointestinal bleeding before transplantation, MELD score, and Child-Pugh score did not show statistical differences between groups. The occurrence of hepatocellular carcinoma and mortality were higher in the hepatitis B Group. The survival in 4 years was 95% in the Delta Group and 75% in the B Group, with a statistically significant difference (P=0.034. Patients with hepatitis delta presented more evident thrombocytopenia in the pre-transplantation and in the immediate postoperative period. CONCLUSION: The hepatitis by delta virus patients who underwent liver transplantation were predominantly male, coming from the Brazilian Amazon region and with similar liver function to the hepatitis B virus patients. They had a lower incidence of hepatocellular carcinoma, more marked perioperative thrombocytopenia levels and frequent

    Liver transplantation has been reported in the literature as an extreme intervention in cases of severe and complicated hepatic trauma. The main indications for liver transplant in such cases were uncontrollable bleeding and postoperative hepatic insufficiency. We here describe four cases of orthotopic liver transplantation after penetrating or blunt liver trauma. The indications were liver failure, extended liver necrosis, liver gangrene and multiple episodes of gastrointestinal bleeding related to portal hypertension, respectively. One patient died due to postoperative cerebral edema. The other three patients recovered well and remain on immunosuppression. Liver transplantation should be considered as a saving procedure in severe hepatic trauma, when all other treatment modalities fail.

    Liver transplant recipients are at an increased risk for liver failure when infected with hepatitis A virus (HAV) and hepatitis B virus (HBV). Therefore, it is important to vaccinate these individuals. The aim of the study was to evaluate how well liver transplanted patients in our unit were protected against HAV and HBV infection. Furthermore we investigated the vaccination rate and the antibody response to vaccination in these liver transplanted patients. Patients liver transplanted from January 2007 until August 2010 with a posttransplant check-up during the period March-November 2010 were included (n = 51). Information considering diagnose, date of transplantation, Child-Pugh score, and vaccination were collected from the patient records. Anti-HAV IgG and anti-HBs titers in serum samples were analyzed and protective levels were registered. Of the patients 45% were protected against hepatitis A infection and 29% against hepatitis B infection after transplantation. Only 26% were vaccinated according to a complete vaccination schedule and these patients had a vaccine response for HAV and HBV of 50% and 31%, respectively. An additional 31% received ≥ 1 doses of vaccine, but not a complete vaccination and the vaccine response was much lower among these patients, stressing the importance of completing the vaccination schedule. Even when patients were fully vaccinated, they did not respond to the same degree as healthy individuals. Patients seemed to be more likely to respond to a vaccination if they had a lower Child-Pugh score, suggesting that patients should be vaccinated as early as possible in the course of their liver disease.

    Objective: To establish a pig model of auxiliary partial liver transplantation and observe the liver function regeneration of host liver and graft. Methods: The portal vein providing for the host liver were gradually contracted; the donor hepatic veins were eng-to-side anastomosed to inferior vena cava in host caudal; graft was transplanted into the space under the host liver, part of receivers relieved portal vein angiography and color Doppler flow imaging was performed 3 days after surgery. Liver function of double livers in relievers was checked up, 3 days and 1 week after surgery respectively. Results: After surgery 10 relievers survived over 1 week, blood enzymology from hepatic vein of grafts 1 week after surgery were not ameliorative significantly compared with those 3 days after surgery (P > 0.05). Blood enzymology indexes from hepatic veins of grafts 1 week after surgery were were improved significantly compared with 3 days after surgery (P < 0.05). The graft did not reveal atrophic and gained favorable function. Conclusion: Favorable regeneration in the auxiliary partial liver transplantation model has achieved. Ideal foundation has been established for simulating and investigating human auxiliary liver transplantation. (authors)

    Anesthesiologists have clearly established their place in the history of medical ethics. Our involvement goes back to 1966 when Henri Beecher published his landmark paper on research and informed consent. Participation in the ethics of transplantation is no less important than our previous work. Organ transplant has been life saving for many but also has given rise to many misunderstandings not just from the public but also among our own colleagues. These include methods of allocation and donation, the role that affluence may play in receiving an organ, the definition of death and donation after circulatory death. As perioperative physicians and important members of the transplant team, anesthesiologists are expected to participate in all aspects of care including ethical judgments. This article discusses some of the issues that seem to cause the most confusion and angst for those of us involved in both liver transplantation and in the procurement of organs. It will discuss the definition of death, donation after circulatory death, the anesthesiologists' role on the selection committee, living donor liver transplantation, and transplantation of patients with alcohol-related liver disease.

    To evaluate the effect of long haul airplane transport of donor livers on post-transplant outcomes. A retrospective cohort study of patients who received a liver transplantation was performed in Perth, Australia from 1992 to 2012. Donor and recipient characteristics information were extracted from Western Australian liver transplantation service database. Patients were followed up for a mean of six years. Patient and graft survival were evaluated and compared between patients who received a local donor liver and those who received an airplane transported donor liver. Predictors of survival were determined by univariate and multivariate analysis using cox regression. One hundred and ninety-three patients received a local donor liver and 93 patients received an airplane transported donor liver. Airplane transported livers had a significantly lower alanine transaminase (mean: 45 U/L vs 84 U/L, P = 0.035), higher donor risk index (mean: 1.88 vs 1.42, P airplane transport retained significance for graft loss (HR = 1.92, 95%CI: 1.16-3.17). One year graft survival was 0.88 for those with a local liver and was 0.71 for those with an airplane transported liver. One year graft loss was due to primary graft non-function or associated with preservation injury in 20.8% of recipients of an airplane transported liver compared with 4.6% in those with a local liver ( P = 0.027). Airplane transport of donor livers was independently associated with reduced graft survival following liver transplantation.

    Objective: The aim of this study was to determine the effectiveness and safety of percutaneous laser ablation for the treatment of cirrhotic patients with hepatocellular carcinoma awaiting liver transplantation. Materials and methods: The data of 9 male cirrhotic patients (mean age 50 years, range 45-60 years) with 12 biopsy proven nodules of hepatocellular carcinoma (mean diameter 2.0 cm, range 1.0-3.0 cm) treated by laser ablation before liver transplantation between June 2000 and January 2006 were retrospectively reviewed. Laser ablation was carried out by inserting 300 nm optical fibers through 21-Gauge needles (from two to four) positioned under ultrasound guidance into the target lesions. A continuous wave Neodymium:Yttrium Aluminium Garnet laser was used. Transarterial chemoembolization prior to liver transplantation was performed in two incompletely ablated tumors. Results: No procedure-related major complications were recorded. During the waiting time to liver transplantation local tumor progression after ablation occurred in 3 nodules (25%). At histological examination of the explanted livers complete necrosis was found in 8 nodules (66.7%, all treated exclusively with laser ablation), partial necrosis >50% in 3 nodules (25%), and partial necrosis <50% in 1 nodule. Conclusion: In patients with cirrhotic livers awaiting liver transplantation, percutaneous laser ablation is safe and effective for the management of small hepatocellular carcinoma.

    Tuberculosis is a rare but serious complication after transplantation. We report a case and discuss its presentation and management. A 60-year-old Indonesian male presented initially with fever, acute confusion and rapidly progressive right upper lobe pneumonia 3.5 months post-liver transplant, and was diagnosed with pulmonary tuberculosis by positive sputum smear for acid-fast bacilli and tuberculosis culture. Standard anti-tuberculosis therapy was administered but was complicated by interaction with cyclosporine and drug-induced cholestasis. A high level of suspicion, prompt antituberculosis treatment and close follow-up are essential in management of post-transplant tuberculosis.

    BACKGROUND: Spinal tuberculosis is a common disease in orthopedic clinical practice; however, it is seldom reported after organ transplantation. The aim of this study was to investigate the diagnosis and treatment of spinal tuberculosis after organ transplantation. METHOD: Two cases were diagnosed as spinal tuberculosis after liver transplantation and were treated with socarboxazide, rifampicin, streptomycin and ethambutol for more than one year. RESULTS: After treatment with anti-tuberculosis drugs for several months, the symptoms of both patients clearly improved. Back pain disappeared, and erythrocyte sedimentation and body temperature returned to normal. CONCLUSIONS: We should highly suspect spinal tuberculosis if notalgia and night sweats are present after organ transplantation. Anti-tuberculosis therapy is an effective treatment for spinal tuberculosis after organ transplantation.

    This study evaluated interventional radiological experience in the management of biliary complications of OLT at the National Cancer Institute of Milan. Seventeen patients who had undergone orthotopic liver transplantation in various hospital were referred to our unit with biliary complications. Group I consisted of 8 patients with anastomotic biliary fistula who came to our attention a short time after transplantation. Group II consisted of 9 patients with anastomotic strictures who came to our attention in a longer period. Two different interventional radiological approaches were used: (a) percutaneous transhepatic biliary drainage (PTBD) in the presence of fistulas in patients of group I; and (b) percutaneous transhepatic biliary drainage combined with dilatation of the strictures with a balloon catheter in patients of group II. On the whole resolution of the biliary complications was achieved in 13 of the 17 cases treated (76.5%), 5 of 8 in group I and 8 of 9 in group II. No secondary stenosis after PTBD were observed in group I, whereas two patients of group II needed a second dilatation. Percutaneous biliary drainage is indicated as a valid treatment in the management of biliary complications, either to allow closure of the fistula either to perform balloon dilatation of stenosis.

    Women constitute a particular group among patients with chronic liver disease and in the post-liver transplantation (LT) setting: they are set apart not only by traditional differences with respect to men (ie, body mass index, different etiologies of liver disease, and accessibility to transplantation) but also in increasingly evident ways related to hormonal changes that characterize first the fertile age and subsequently the postmenopausal period (eg, disease course variability and responses to therapy). The aim of this review is, therefore, to evaluate the role of the interplay of factors such as age, gender, and hormones in influencing the natural history of chronic liver disease before and after LT and their importance in determining outcomes after LT. As the population requiring LT ages and the mean age at transplantation increases, older females are being considered for transplantation. Older patients are at greater risk for nonalcoholic steatohepatitis, osteoporosis, and a worse response to antiviral therapy. Female gender per se is associated with a greater risk for osteoporosis because of metabolic changes after menopause, the bodily structure of females, and, in the population of patients with chronic liver disease, the greater prevalence of cholestatic and autoimmune liver diseases. With menopause, the fall of protective estrogen levels can lead to increased fibrosis progression, and this represents a negative turning point for women with chronic liver disease and especially for patients with hepatitis C. Therefore, the notion of gender as a binary female/male factor is now giving way to the awareness of more complex disease processes within the female gender that follow hormonal, social, and age patterns and need to be addressed directly and specifically.

    Full Text Available Abstract Background Ischemia-reperfusion (I/R causes a dramatic reprogramming of cell metabolism during liver transplantation and can be linked to an alteration of the phosphorylation level of several cellular proteins. Over the past two decades, it became clear that tyrosine phosphorylation plays a pivotal role in a variety of important signalling pathways and was linked to a wide spectrum of diseases. Functional profiling of the tyrosine phosphoproteome during liver transplantation is therefore of great biological significance and is likely to lead to the identification of novel targets for drug discovery and provide a basis for novel therapeutic strategies. Results Using liver biopsies collected during the early phases of organ procurement and transplantation, we aimed at characterizing the global patterns of tyrosine phosphorylation during hepatic I/R. A proteomic approach, based on the purification of tyrosine phosphorylated proteins followed by their identification using mass spectrometry, allowed us to identify Nck-1, a SH2/SH3 adaptor, as a potential regulator of I/R injury. Using immunoblot, cell fractionation and immunohistochemistry, we demonstrate that Nck-1 phosphorylation, expression and localization were affected in liver tissue upon I/R. In addition, mass spectrometry identification of Nck-1 binding partners during the course of the transplantation also suggested a dynamic interaction between Nck-1 and actin during I/R. Conclusion Taken together, our data suggest that Nck-1 may play a role in I/R-induced actin reorganization, which was previously reported to be detrimental for the hepatocytes of the transplanted graft. Nck-1 could therefore represent a target of choice for the design of new organ preservation strategies, which could consequently help to reduce post-reperfusion liver damages and improve transplantation outcomes.

    Mycophenolate sodium (EC-MPS) has been shown to be as effective and as safe as mycophenolate mofetil (MMF) in renal transplant patients. Nevertheless, compared to MMF its use in liver transplant patients has been limited. The purpose of this study was to analyze the efficacy of EC-MPS as a primary immunosuppressant or as a replacement for MMF in liver transplant patients. Ninety among 470 liver transplant recipients were receiving or had added an antimetabolite to their immunosuppressant therapy. The most common reason for this change was renal dysfunction (47.8%) or diabetes (32.2%). EC-MPS was started at a median of 30 months after liver transplantation. The mean administered daily dose was 720 mg/d. At least one gastrointestinal symptom was reported by 25 patients. Abdominal pain (16.6%) and diarrhea (14.5%) were the most frequent. EC-MPS had to be discontinued in two patients, while six others required dose reduction to resolve the symptoms. Hematological adverse events were infrequent: three patients had leukopenia and one, anemia, all of which responded to dosage reduction. There was a creatinine reduction within 6 months of drug commencement and maintenance of the lower creatinine levels at 1 year among patients who began EC-MPS for renal dysfunction. Serum low-density lipoprotein cholesterol and triglyceride levels were significantly lower among patients on EC-MPS than on MMF. In conclusion, EC-MPS appears to have a similar efficacy and safety profile as MMF in liver transplant patients. Hematological and gastrointestinal adverse events were infrequent; seldom had the drug to be discontinued.

    Background The avoidance of hypothermia is vital during prolonged and open surgery to improve patient outcomes. Hypothermia is particularly common during orthotopic liver transplantation (OLT) and associated with undesirable physiological effects that can adversely impact on perioperative morbidity. The KanMed WarmCloud (Bromma, Sweden) is a revolutionary, closed-loop, warm-air heating mattress developed to maintain normothermia and prevent pressure sores during major surgery. The clinical effectiveness of the WarmCloud device during OLT is unknown. Therefore, we conducted a randomized controlled trial to determine whether the WarmCloud device reduces hypothermia and prevents pressure injuries compared with the Bair Hugger underbody warming device. Methods Patients were randomly allocated to receive either the WarmCloud or Bair Hugger warming device. Both groups also received other routine standardized multimodal thermoregulatory strategies. Temperatures were recorded by nasopharyngeal temperature probe at set time points during surgery. The primary endpoint was nasopharyngeal temperature recorded 5 minutes before reperfusion. Secondary endpoints included changes in temperature over the predefined intraoperative time points, number of patients whose nadir temperature was below 35.5°C and the development of pressure injuries during surgery. Results Twenty-six patients were recruited with 13 patients randomized to each group. One patient from the WarmCloud group was excluded because of a protocol violation. Baseline characteristics were similar. The mean (standard deviation) temperature before reperfusion was 36.0°C (0.7) in the WarmCloud group versus 36.3°C (0.6) in the Bairhugger group (P = 0.25). There were no statistical differences between the groups for any of the secondary endpoints. Conclusions When combined with standardized multimodal thermoregulatory strategies, the WarmCloud device does not reduce hypothermia compared with the Bair Hugger device in

    To define the changes in liver and spleen volumes in the early postoperative period after partial liver donation for living-donor liver transplantation (LDLT) and to determine factors that influence liver and spleen volume changes. 27 donors who underwent partial hepatectomy for LDLT were included in this study. The rates of liver and spleen volume change, measured with CT volumetry, were correlated with several factors. The analyzed factors included the indocyanine green (ICG) retention rate at 15 minutes after ICG administration, preoperative platelet count, preoperative liver and splenic volumes, resected liver volume, resected-to-whole liver volume ratio (LV{sub R}/LV{sub W}), resected liver volume to the sum of whole liver and spleen volume ratio [LV{sub R}/(LV{sub W} + SV{sub 0})], and pre and post hepatectomy portal venous pressures. In all hepatectomy donors, the volumes of the remnant liver and spleen were increased (increased rates, 59.5 ± 50.5%, 47.9 ± 22.6%). The increment rate of the remnant liver volume revealed a positive correlation with LV{sub R}/LV{sub W} (r = 0.759, p < 0.01). The other analyzed factors showed no correlation with changes in liver and spleen volumes. The spleen and remnant liver volumes were increased at CT volumetry performed 2 weeks after partial liver donation. Among the various analyzed factors, LV{sub R}/LV{sub W} influences the increment rate of the remnant liver volume.

    Narrative medicine allows professionals from all fields of medical sciences to understand the patient's total experience of illness, and meet his/her needs in an empathetic environment. Narrative medicine helps spread holistic knowledge of a multitude of complex clinical conditions, including transplantation. To underline the role of narrative medicine in women who become pregnant after a liver transplant by using their narrations of this very special experience. We describe our study with narration and listening to the stories of three women expecting their first child after a liver transplant, by analysing the structure and role of narration in the context of relationships between patients and caregivers. The narrations were transcribed verbatim with the main plot analysed in order to address all the aspects of this rare clinical condition and the transition to parenthood. The women narrated this experience in three phases: transplantation, pregnancy and delivery, and post-partum. They described all phases of pregnancy as stressful but satisfying, whereas the fact of becoming a mother was perceived as a victory both as a woman and as a transplant patient. Our results suggest that narrative medicine represents a significant professional tool for caring for transplant patients during pregnancy.

    A considerable number of patients with portal hypertension (PHT) have to undergo splenectomy because they do not meet the requirements for liver transplantation (LT) or cannot find a suitable liver donor. However, it is not known whether pre-transplantation splenectomy may create occult difficulties for patients who require LT in future. We analyzed 1059 consecutive patients who underwent adult liver transplantation (ADLT). Patients with pre-transplantation splenectomy Sp(+) and without splenectomy Sp(-) were compared using a propensity score analysis to create the best match between groups. There were no differences between patients in group Sp(+) and group Sp(-) with respect to the main post-operative infections (12.20% vs. 15.85%, P = 0.455), and the incidence of major complications (6.10% vs. 10.98%, P = 0.264). The post-operative platelet count was significantly higher in group Sp(+) (P = 0.041), while group Sp(-) had a higher rate of post-operative thrombocytopenia (91.46% vs. 74.39%, P = 0.006) and early allograft dysfunction (EAD) (23.20% vs. 10.98%, P = 0.038). The 5-year overall survival rates were similar in groups Sp(-) and Sp(+) (69.7% vs. 67.6%, P = 0.701). Compared with Sp(-), the risk of infection and post-operative complications in group Sp(+) was not increased, while group Sp(-) had a higher rate of post-operative EAD. Moreover, pre-transplantation splenectomy is very effective for the prevention of thrombocytopenia after LT. Pre-transplantation splenectomy is recommended in cases with risky PHT patients without appropriate source of liver for LT.

    Hepatocellular carcinoma (HCC) is one of the most common malignancies worldwide. Annually, about 200,000 patients died of HCC in China. Liver transplantation (LT) holds great theoretical appeal in treating HCC. However, the high recurrence rate after transplantation is the most important limiting factor for long-term survival. To assess the value of alpha-fetoprotein (AFP) messenger RNA (mRNA), Glypican-3 (GPC3) mRNA-expressing cells in the peripheral blood (PB) for prediction of HCC recurrence following orthotopic liver transplantation (OLT). 29 patients with HCC who underwent OLT with a minimum clinical follow-up of 12 months were included in this retrospective study. We detected AFP mRNA, GPC3 mRNA-expressing cells in the PB by TaqMan real-time reverse transcriptase-polymerase chain reaction (RT-PCR), pre-, intra- and post-operatively. The early recurrence of patients was evaluated. 8 (28%), 15 (52%), and 9 (31%) patients had AFP mRNA detected pre-, intra-, and post-operatively, respectively. With 12 months of follow-up, HCC recurred in 7 (24%) patients. Univariate analysis revealed that positive pre- and post-operative AFP mRNA, TNM stage as well as vascular invasion were significant predictors for the HCC recurrence. Multivariate analysis revealed that being positive for AFP mRNA pre-operatively remained a significant risk factor for HCC recurrence after OLT. GPC3 mRNA was expressed in all PB samples. There was no significant difference in the expression levels of GPC3 mRNA between the HCC and control groups. There were no significant differences in GPC3 mRNA expression values between those patients with and without tumor recurrence. The pre-operative detection of circulating AFP mRNA-expressing cells could be a useful predictor for HCC recurrence following OLT. GPC3 mRNA-expressing cells in PB seem to have no diagnostic value.

    Liver transplantation centers are unevenly distributed within the Donor Service Areas (DSAs) of the United States. This study assessed how market competition and liver transplantation center density are associated with liver transplantation volume within individual DSAs. We conducted a retrospective cohort study of 53,156 adult liver transplants in 45 DSAs with 110 transplantation centers identified from the Scientific Registry of Transplant Recipients between 2003 and 2012. The following measures were derived annually for each DSA: market competition using the Herfindahl Hirschman Index, transplantation center density by the Average Nearest Neighbor method, liver quality by the Liver Donor Risk Index, and patient risk by the Model for End-Stage Liver Disease. A hierarchical mixed effects negative binomial regression model of the relationship between liver transplants and market factors was created annually. Patient and graft survival were investigated with a Cox proportional hazards model. Transplantation center density was associated with market competition (p market competition (IRR = 1.36; p = 0.02), increased listings (IRR = 1.14; p market variables were associated with increased mortality after transplantation. After controlling for demographic and market factors, a greater concentration of centers was associated with more liver transplants without impacting overall survival. These results warrant additional investigation into the relationship between geospatial factors and liver transplantation volume with consideration for the optimization of scarce resources.

    1997-04-01

    The authors report the case of a 48-year-old man in whom candida (Torulopsis glabrata) liver abscesses developed 8 years after liver transplantation. After a week of fever, computed tomography and Doppler ultrasonography showed several fluid-filled loculations in the left lobe of the liver and hepatic arterial stenosis. Aspirates from the abscesses contained T. glabrata organisms. This complication probably developed because hepatic arterial stenosis resulted in bile infarcts (bilomas), which were contaminated via the biliary tract with candida from the biliary-enteric anastomosis. Catheter drainage and administration of amphotericin B for 10 weeks permitted successful retransplantation. T. glabrata liver abscesses, a life threatening complication that can occur long after liver transplantation, can be successfully managed by aggressive medical treatment followed by retransplantation.

    BACKGROUND T lymphocytes are an essential component of allograft rejection and tolerance. The aim of the present study was to analyze and compare the characteristics of T cell subsets in patients who underwent deceased donor liver transplantation (DDLT) versus living donor liver transplantation (LDLT). MATERIAL AND METHODS Between April 2013 and June 2014, 64 patients underwent adult liver transplantation. The distribution of peripheral blood T lymphocyte subsets before transplantation and at 4, 8, 12, and 24 weeks post-transplantation were monitored serially. RESULTS In the serial peripheral blood samples, the absolute CD3+ T cell counts in the LDLT group were higher than those in the DDLT group (p=0.037). The CD4+, CD8+, CD4/CD8, Vδ1, Vδ2, and γδ T cell counts did not change significantly over time in either group. The Vδ1/Vδ2 ratio was higher in patients with cytomegalovirus (CMV) infection than in patients without CMV infection (0.12 versus 0.26; p=0.033). The median absolute CD3+ and CD8+ T cell counts in patients with biopsy-proven acute rejection (BPAR) were 884 (range, 305-1,320) and 316 (range, 271-1,077), respectively, whereas they were 320 (range, 8-1,167) and 257 (range, 58-1,472) in patients without BPAR. The absolute CD3+ and CD8 T cell counts were higher in patients with BPAR than in patients without BPAR (p=0.007 and p=0.039, respectively). CONCLUSIONS With the exception of CD3+ T cells, T cell populations did not differ significantly between patients who received DDLT versus LDLT. In liver transplantation patients, CMV infection and BPAR were closely associated with T cell population changes.

    AIM: To investigate the incidence and risk factors of late-onset acute rejection (LAR) and to clarify the effectiveness of our immunosuppressive regime consisting of life-long administration of tacrolimus and steroids.METHODS: Adult living donor liver transplantation recipients (n = 204) who survived more than 6 mo after living donor liver transplantation were enrolled.Immunosuppression was achieved using tacrolimus and methylprednisolone. When adverse effects of tacrolimus were detected, the patient was switched to cyclosporine. Six months after transplantation,tacrolimus or cyclosporine was carefully maintained at a therapeutic level. The methylprednisolone dosage was maintained at 0.05 mg/kg per day by oral administration.Acute rejections that occurred more than 6 mo after the operation were defined as late-onset. The median followup period was 34 mo.RESULTS: LAR was observed in 15 cases (7%) and no chronic rejection was observed. The incidence of hyperlipidemia, chronic renal failure, new-onset posttransplantation diabetes, and deep fungal infection were 13%, 2%, 24%, and 17%, respectively. Conversion from tacrolimus to cyclosporine was required in 38 patients (19%). Multivariate analysis revealed that a cyclosporinebased regimen was significantly associated with LAR.CONCLUSION: Both LAR and drug-induced adverse events happen at a low incidence, supporting the safety and efficacy of the present immunosuppression regimen for living donor liver transplantation.

    To define the changes in liver and spleen volumes in the early postoperative period after partial liver donation for living-donor liver transplantation (LDLT) and to determine factors that influence liver and spleen volume changes. 27 donors who underwent partial hepatectomy for LDLT were included in this study. The rates of liver and spleen volume change, measured with CT volumetry, were correlated with several factors. The analyzed factors included the indocyanine green (ICG) retention rate at 15 minutes after ICG administration, preoperative platelet count, preoperative liver and splenic volumes, resected liver volume, resected-to-whole liver volume ratio (LV R /LV W ), resected liver volume to the sum of whole liver and spleen volume ratio [LV R /(LV W + SV 0 )], and pre and post hepatectomy portal venous pressures. In all hepatectomy donors, the volumes of the remnant liver and spleen were increased (increased rates, 59.5 ± 50.5%, 47.9 ± 22.6%). The increment rate of the remnant liver volume revealed a positive correlation with LV R /LV W (r = 0.759, p R /LV W influences the increment rate of the remnant liver volume.

    Full Text Available Aim: optimization of the surgical treatment policy with orthotopic liver transplantation (OLT depending on the results of intraoperative fl owmetry and the state of intrahepatic microcirculatory bloodstream according to immunohistochemical (IHC study of microspecimens of the donor’s liver.Materials and methods. 60 patients are included in the study. Group I (n = 30 comprised of patients for whom it was not necessary to perform any additional interventions on the bloodstream in the hepatopancreatobiliary area during OLT. Group II (n = 30 had patients with insuffi cient arterial blood supply for the graft in the intraoperative stage where it was needed to perform additional and/or repeated interventions in the arteries of the hepatopancreatobilliary area. Intraoperative fl owmetry with assessment of the volume blood circulation (VBC in the hepatic artery (HA was carried out in the both studied groups. Reference value of VBC was 100 ml/min and higher. Before and after reperfusion in the liver biopsy material we performed immunohistochemical study with the use of endothelial marker CD 31 with subsequent morphometric estimation of the specifi c square of the microvascular bloodstream.Results. In both groups there was no change in the specifi c square in the areas of portal tract and central vein before and after restoring blood fl ow. In the second group, an 8 times increase of the specifi c square of sinusoids was observed after restoring blood fl ow (р < 0,01.Conclusion. Intraoperative fl owmetric control of the blood fl ow allows in due time to perform surgical correction of the graft arterial blood supply during OLT, and it reduces the risk of thrombosis up to 0%. The value of VBC in the hepatic artery (HA has reliable dependence upon the state of microcirculatory bloodstream of cadaveric donor’s liver after reperfusion.

    Liver transplantation is widely accepted as an effective therapy of hepatoma. Perioperative dynamic observation of coagulation function is important for graft-receivers. This study was to explore perioperative changes of coagulation functions in the local advanced liver cancer patients who received liver transplantation. Clinical data of 31 local advanced liver cancer patients, underwent liver transplantation from Sep. 2003 to Jan. 2007, were analyzed. Platelet (PLT) counting, prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT), fibrinogen (Fib) and international normalized ratio (INR) before operation, at anhepatic phase and the first week after operation were analyzed to evaluate congulation function. The coagulation functions of most patients were normal before operation. The six parameters varied significantly at anhepatic phase and on most days of the first week after operation when compared with the preoperative levels (Pfunctions of local advanced liver cancer patients shift from hypocoagulatory to hypercoagulatory or normal in perioperative period, therefore, prevention of bleeding should be focused on at anhepatic phase and on 1-2 days after operation while prevention of thrombosis should be focused on after the first week after operation. The degree of liver cirrhosis and Child-Pugh level could help to evaluate postoperative coagulation disorder.

  7. New diagnosis and therapy model for ischemic-type biliary lesions following liver transplantation--a retrospective cohort study.

    Directory of Open Access Journals (Sweden)

    Ying-cai Zhang

    Full Text Available Ischemic-type biliary lesions (ITBLs are a major cause of graft loss and mortality after orthotopic liver transplantation (OLT. Impaired blood supply to the bile ducts may cause focal or extensive damage, resulting in intra- or extrahepatic bile duct strictures or dilatations that can be detected by ultrasonography, computed tomography, magnetic resonance cholangiopancreatography, and cholangiography. However, the radiographic changes occur at an advanced stage, after the optimal period for therapeutic intervention. Endoscopic retrograde cholangio-pancreatography (ERCP and percutaneous transhepatic cholangiodrainage (PTCD are the gold standard methods of detecting ITBLs, but these procedures cannot be used for continuous monitoring. Traditional methods of follow-up and diagnosis result in delayed diagnosis and treatment of ITBLs. Our center has used the early diagnosis and intervention model (EDIM for the diagnosis and treatment of ITBLs since February 2008. This model mainly involves preventive medication to protect the epithelial cellular membrane of the bile ducts, regular testing of liver function, and weekly monitor of contrast-enhanced ultrasonography (CEUS to detect ischemic changes to the bile ducts. If the liver enzyme levels become abnormal or CEUS shows low or no enhancement of the wall of the hilar bile duct during the arterial phase, early ERCP and PTCD are performed to confirm the diagnosis and to maintain biliary drainage. Compared with patients treated by the traditional model used prior to February 2008, patients in the EDIM group had a lower incidence of biliary tract infection (28.6% vs. 48.6%, P = 0.04, longer survival time of liver grafts (24±9.6 months vs. 17±12.3 months, P = 0.02, and better outcomes after treatment of ITBLs.

    The authors report the experience of our general hospital in selecting the patients for orthotopic liver transplantation (OLT). The accuracy of duplex Doppler and color flow Doppler for portal and/or mesenteric vein thrombosis was evaluated by correlation with resected livers, computerized tomography and angiographic findings. Pathologic examinations diagnosed HCC in 5/20 transplant recipients: 2 lesions were found in 2 resected specimens (total hepatectomy) and 1 lesion was found in 3 cases. The sensitivity of US, plain and dynamic computerized tomography in identifying HCC patients was 20%; US and computerized tomography specificity rates were 100% and 87%, respectively. CTAP sensitivity was 75% and the sensitivity of Lipiodol computerized tomography and angiography was 100%. Therefore, in our series, US was poorly sensitivity in the detection of liver cancers, which may depend on the small number of patients, lesion size and the radiologists ignoring clinical and laboratory data on purpose. Nevertheless, the patients with a single HCC not exceeding 5 cm in diameter or with no more than 3 tumors, none of them exceeding 3 cm in diameter, are generally considered eligible for transplantation: therefore, our patients chosen for OLT on the basis of US and computerized tomography findings were actually eligible for transplantation in spite of US and computerized tomography false negative results. In conclusion, considering also the long stand-by list for OLT, the first selection of transplant candidates could be performed with US and color flow Doppler, plain and dynamic computerized tomography. The patients who are not ruled out as candidates for OLT on the basis of the findings of these imaging techniques and of clinical and laboratory findings are submitted to no further examination and referred to the transplantation unit. Otherwise, if conventional and color flow Doppler US and conventional computerized tomography are not enough to exclude a patient from OLT, the

    As survival rates for pediatric liver transplantation continue to increase, research attention is turning towards long-term functional consequences, with particular interest in whether medical and transplant-related factors are implicated in neurocognitive outcomes. The relative importance of different factors is unclear, due to a lack of methodological uniformity, inclusion of differing primary diagnoses, variable transplant policies, and organ availability in different jurisdictions. This cross-sectional, single-site study sought to address various methodological limitations in the literature and the paucity of studies conducted outside of North America and Western Europe by examining the intellectual and academic outcomes of Australian pediatric liver transplant recipients (N = 40). Participants displayed significantly poorer intellectual and mathematical abilities compared to the normative population. Greater time on the transplant waitlist was a significant predictor of poorer verbal intelligence, working memory, mathematical abilities and reading, but only when considering the subgroup of children with biliary atresia. These findings support reducing the time children wait for a transplant as a priority. This article is protected by copyright. All rights reserved. This article is protected by copyright.

    Hepatopulmonary syndrome (HPS) is a complication of portal hypertension, defined by the presence of liver disease, abnormal pulmonary gas exchange and evidence of intrapulmonary vascular dilatations producing a right-to-left intrapulmonary shunt. Liver transplantation (LT) is the treatment of choice; however, severe hypoxemia (PaO(2) < 50 mmHg on room air) is considered a contraindication to LT. This approach disadvantages some patients, particularly young patients with no intrinsic cardio-respiratory disease. We discuss one such patient who improved with LT despite having extremely severe HPS (PaO2 < 29 mmHg).

The MELD score was determined prior to transplantation and daily until 21 days after. The risk of mortality or re-transplantation within the first year was assessed...... day 1 the MELD score significantly diversified and was higher in the poor outcome group (MELD score quartile 4 versus quartile 1-3 at day 10: HR 5.1, 95% CI: 2.8-9.0). This association remained after adjustment for non-identical blood type, autoimmune liver disease and hepatocellular carcinoma...... (adjusted HR 5.3, 95% CI: 2.9-9.5 for MELD scores at day 10). The post-transplant MELD score was not associated with pre-transplant MELD score or the Eurotransplant donor risk index.

    Over the last decade, liver transplantation of sicker, older non-hepatitis C cirrhotics with multiple co-morbidities has increased in the United States. We sought to identify an easily applicable set of recipient factors among HCV negative adult transplant recipients associated with significant morbidity and mortality within five years after liver transplantation. We collected national (n = 31,829, 2002-2015) and center-specific data. Coefficients of relevant recipient factors were converted to weighted points and scaled from 0-5. Recipient factors associated with graft failure included: ventilator support (five patients; hazard ratio [HR] 1.59; 95% CI 1.48-1.72); recipient age >60 years (three patients; HR 1.29; 95% CI 1.23-1.36); hemodialysis (three patients; HR 1.26; 95% CI 1.16-1.37); diabetes (two patients; HR 1.20; 95% CI 1.14-1.27); or serum creatinine ≥1.5 mg/dl without hemodialysis (two patients; HR 1.15; 95% CI 1.09-1.22). Graft survival within five years based on points (any combination) was 77.2% (0-4), 69.1% (5-8) and 57.9% (>8). In recipients with >8 points, graft survival was 42% (model for end-stage liver disease [MELD] score recipients receiving grafts from donors with a donor risk index >1.7. In center-specific data within the first year, subjects with ≥5 points (vs. 0-4) had longer hospitalization (11 vs. 8 days, p need to be reassessed. The proposed clinical tool may be helpful for center-specific assessment of risk of graft failure in non-HCV patients and for discussion regarding relevant morbidity in selected subsets. Over the last decade, liver transplantation of sicker, older patient with multiple co-morbidities has increased. In this study, we show that a set of recipient factors (recipient age >60 years, ventilator status, diabetes, hemodialysis and creatinine >1.5 mg/dl) can help identify patients that may not do well after transplant.

    Full Text Available CONTEXT: Most patients subjected to liver transplantation presents hypersplenism, which is reversed after the operation. However, some patients remain with moderate to intense hypersplenism. OBJECTIVES: To study the effect of liver transplantation on platelet count in patients with hypersplenism. METHOD: Of a total of 233 patients who underwent liver transplantation, 162 were excluded from the present study because of occurrence of steroid-resistant rejection, absence of hypersplenism before the transplantation, absence of follow-up for at least 2 years or incomplete exams data. The electronic study protocols of the remaining 71 patients were reviewed to determine the demographics, etiology of cirrhosis, and results of pathologic examination of the explanted liver. Serial platelet count was obtained from the study protocol on the day before liver transplantation and 1, 2, 4, and 6 months and 1 year after liver transplantation. Statistical analysis was performed using the Student's t-test, chi-square test, and Spearman's correlation test. RESULTS: Posttransplant platelet count at all time intervals was significantly higher than the pretransplant value (P100,000/mm³ in 58 patients (81.7% 1 month after liver transplantation. Twelve patients (16.9% remained with thrombocytopenia 1 year after liver transplantation. Three patients (4.2% had recurrence of thrombocytopenia within 1 year after liver transplantation. There was no correlation between pretransplant platelet count and the Child-Pugh class or the MELD score. CONCLUSION: Liver transplantation reverses hypersplenism in most patients.

    Introduction The model for end-stage liver disease (MELD) score is used in many countries to prioritize organ allocation for the majority of patients who require orthotopic liver transplantation. This score is calculated based on the following laboratory parameters: creatinine, bilirubin and the international normalized ratio (INR). Consequently, high measurement accuracy is essential for equitable and fair organ allocation. For serum creatinine measurements, the Jaffé method and enzymatic detection are well-established routine diagnostic tests. Methods A total of 1,013 samples from 445 patients on the waiting list or in evaluation for liver transplantation were measured using both creatinine methods from November 2012 to September 2013 at the university hospital Leipzig, Germany. The measurements were performed in parallel according to the manufacturer’s instructions after the samples arrived at the institute of laboratory medicine. Patients who had required renal replacement therapy twice in the previous week were excluded from analyses. Results Despite the good correlation between the results of both creatinine quantification methods, relevant differences were observed, which led to different MELD scores. The Jaffé measurement led to greater MELD score in 163/1,013 (16.1%) samples with differences of up to 4 points in one patient, whereas differences of up to 2 points were identified in 15/1,013 (1.5%) samples using the enzymatic assay. Overall, 50/152 (32.9%) patients with MELD scores >20 had higher scores when the Jaffé method was used. Discussion Using the Jaffé method to measure creatinine levels in samples from patients who require liver transplantation may lead to a systematic preference in organ allocation. In this study, the differences were particularly pronounced in samples with MELD scores >20, which has clinical relevance in the context of urgency of transplantation. These data suggest that official recommendations are needed to determine which

    Liver transplantation (LT) for hepatocellular carcinoma (HCC) at Kaohsiung Chang Gung Memorial Hospital mainly relies on live donor LT (LDLT). Owing to taking the risk of LD, we are obligated to adopt strict selection criteria for HCC patients and optimize the pre-transplant conditions to ensure a high disease-free survival similar to those without HCC, even better than deceased donor LT (DDLT). Better outcomes are attributed to excellent surgical results and optimal patient selection. The hospital mortality of primary and salvage LDLT are lower than 2% in our center. Although Taiwan Health Insurance Policy extended the Milan to University of California, San Francisco (UCSF) criteria in 2006, selection criteria will not be consolidated to take into account only by the morphologic size/number of tumors but also by their biology. The criteria are divided into modifiable image morphology, alpha fetoprotein (AFP), and positron emission tomography (PET) scan with standard uptake value (SUV) and unmodifiable unfavorable pathology such as HCC combined with cholangiocarcinoma (CC), sarcomatoid type, and poor differentiation. Downstaging therapy is necessary for HCC patients beyond criteria to fit all modifiable standards. The upper limit of downstaging treatment seems to be extended by more effective drug eluting transarterial chemoembolization in cases without absolute contraindications. In contrast, the pitfall of unmodifiable tumor pathology should be excluded by the findings of pretransplant core biopsy/resection if possible. More recently, achieving complete tumor necrosis in explanted liver could almost predict no recurrence after transplant. Necrotizing therapy is advised if possible before transplant even the tumor status within criteria to minimize the possibility of tumor recurrence. LDLT with low surgical mortality in experienced centers provides the opportunities of optimizing the pre-transplant tumor conditions and timing of transplant to achieve better

    Full Text Available Still's disease (SD is a multisystemic inflammatory disease characterized by persistent arthritis and in many cases with fever of unknown origin. Diagnosis of SD is challenging because of nonspecific characteristics and especially in the case of a patient with solid organ transplantation and immunosuppressive therapy where multiple causes of fever are possible. There is no diagnostic test for SD, even though some useful diagnostic criteria or laboratory findings, such as serum ferritin levels, have been proposed, and useful imaging studies for the diagnosis or followup of SD have not been developed. We report the case of a 9-year-old child who presented with high grade fever associated with joint pain after a history of liver transplantation and immunosuppressive therapy. Laboratory tests showed increased acute phase reactants, elevated ferritin, and leukocytosis. An 18 F-fluorodeoxyglucose positron emission tomography (18F-FDG PET was performed identifying abnormal hypermetabolic areas localized in spleen, transplanted liver, and bone marrow secondary to inflammatory process. All infectious, autoimmune, and malignant causes were ruled out. A diagnosis of SD was performed and a steroid-based regimen was initiated with adequate response and no evidence of recurrence. To our knowledge this is the first case of SD following a solid organ transplant.

    Citation counts can identify landmark papers. The aim of this study was to identify and characterize the top-cited articles in the pediatric liver transplantation literature. A search strategy for the Scopus ® database was designed for pediatric liver transplantation publications from 1945 to 2014. The 50 top-cited articles were analyzed. Author co-citation analysis was performed using VOSviewer techniques. There were 2896 articles published between 1969 and 2015. The mean citation count of the top 50 cited articles was 166 (range 95-635). There were three case reports in this top-cited list. There were 15 collaborations in this top-cited list with nine being international. The top-cited publications originated in 12 countries, with the USA and the UK contributing 31 and seven articles, respectively. There were 14 authors with four or more publications in this list. There was a single author with nine publications in the top-cited list. These top-cited papers were found in 16 journals, with three journals collectively publishing over 50% of these publications. Pediatric liver transplantation research is an evolving entity. Surgical techniques and case reports are influential articles. Collaborations at a national and international level produce highly cited articles, which are found in influential journals. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

  18. Bypass during Liver Transplantation: Anachronism or Revival? Liver Transplantation Using a Combined Venovenous/Portal Venous Bypass—Experiences with 163 Liver Transplants in a Newly Established Liver Transplantation Program

    Directory of Open Access Journals (Sweden)

    Anne Mossdorf

    2015-01-01

    Full Text Available 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.

    The aim of the study was to evaluate the cognitive and emotional development after pediatric liver transplantation. A total of 21 patients, aged 4-16.9 yr (median 9.6 yr) were tested 1-9 yr (median 4.2 yr) after the transplantation. The pretransplant diagnoses included biliary atresia (eight patients), various metabolic diseases (n = 6), acute liver failure (n = 3), and miscellaneous (n = 4). The cognitive functions were tested with Wechsler preschool and primary scale of intelligence (WPPSI)-R or Wechsler intelligence scale for children (WISC)-III according to age. The Piers-Harris self-concept scale and the evaluation of human figure drawings according to Koppitz were used to detect emotional problems. All tests in all patients were performed by the same psychologist. A significantly lower result on cognitive tests was seen when compared with the expected normal values (p emotional problems were found in the human figure drawings of 50% of the patients. To some extent, low cognitive scores coincided with low scores on self-concept scale and indicators of emotional difficulties. We conclude that the high degree of cognitive and emotional problems after liver transplantation is an important argument for routine psychologic follow-up and support in these patients.

    Full Text Available Introduction: Liver transplant recipients are at risk for complications of vascular thrombosis. The reconstructed hepatic artery and portal vein thrombosis potentially result in hepatic failure and graft loss. Renal infarction is a rare clinical condition, but in severe cases, it may lead to renal failure. We herein report a case of renal infarction after living donor liver transplantation (LDLT during anticoagulant therapy. Case Presentation: A 60-year-old woman with end-stage liver disease due to primary biliary cholangitis underwent LDLT with splenectomy. Postoperatively, tacrolimus, mycophenolate mofetil, and steroid were used for initial immunosuppression therapy. On postoperative day (POD 5, enhanced computed tomography (CT revealed splenic vein thrombosis, and anticoagulant therapy with heparin followed by warfarin was given. Follow-up enhanced CT on POD 20 incidentally demonstrated right renal infarction. The patient’s renal function was unchanged and the arterial flow was good, and the splenic vein thrombosis resolved. At 4 months postoperatively, warfarin was discontinued, but she developed recurrent splenic vein thrombosis 11 months later, and warfarin was resumed. As of 40 months after transplantation, she discontinued warfarin and remains well without recurrence of splenic vein thrombosis or renal infarction. Conclusion: Renal infarction is a rare complication of LDLT. In this case, renal infarction was incidentally diagnosed during anticoagulant therapy and was successfully treated.

    While hepatocellular carcinoma is a common indication for liver transplantation, intrahepatic cholangiocarcinoma represents a controversial indication for this procedure, due to lower disease-free and overall survival rates achieved by liver transplantation in such patients. Hence, in the last years, few centers reported satisfactory survival rates after liver transplantation for cholangiocarcinoma, in highly selected groups of patients. Herein we present the clinicopathological characteristics, the pre- and postoperative management and the favorable outcome of a patient undergoing liver transplantation for an unresectable intrahepatic cholangiocarcinoma. We consider that reporting the patients with such favorable outcomes is useful, since collecting the data presented by different centers may contribute to identification of a selected group of patients with cholangiocarcinoma who may benefit from liver transplantation. A 62-year old female patient with a primary liver tumor developed on HBV liver cirrhosis, was admitted in our center for therapeutical management. Since preoperative work-up suggested that the tumor is an unresectable hepatocellular carcinoma (due to its location and underlying liver disease), we decided to perform liver transplantation. The pathological examination of the explanted liver revealed that the tumor was a stage I intrahepatic cholangiocarcinoma. The postoperative course was uneventful, and in present, 15 months after transplantation, the patient is alive, without recurrence. Liver transplantation may represent a valid therapeutical option in selected patients with intrahepatic cholangiocarcinoma. Patients with early stage intrahepatic cholangiocarcinomas unresectable due to the underlying liver cirrhosis seem to benefit mostly by liver transplantation. Further studies are needed to identify the favorable prognostic factors in order to select the most appropriate candidates for liver transplantation. The most suitable immunosuppressive

    In 2011, a pilot program for deceased organ donation was initiated in China. We describe the first successful series of liver transplants in the pilot program. From July 2011 to August 2012, our center performed 26 liver transplants from a pool of 29 deceased donors. All organ donation and allograft procurement were conducted according to the national protocol. The clinical data of donors and recipients were collected and summarized retrospectively. Among the 29 donors, 24 were China Category II donors (organ donation after cardiac death), and five were China Category III donors (organ donation after brain death followed by cardiac death). The recipients were mainly the patients with hepatocellular carcinoma. The one-year patient survival rate was 80.8% with a median follow-up of 422 (2-696) days. Among the five mortalities during the follow-up, three died of tumor recurrence. In terms of post-transplant complications, 9 recipients (34.6%) experienced early allograft dysfunction, 1 (3.8%) had non-anastomotic biliary stricture, and 1 (3.8%) was complicated with hepatic arterial thrombosis. None of these complications resulted in patient death. Notably, primary non-function was not observed in any of the grafts. With careful donor selection, liver transplant from deceased donors can be performed safely and plays a critical role in overcoming the extreme organ shortage in China.

    The indications for simultaneous and sequential pediatric liver (LTx) and kidney (KTx) transplantation have not been well defined. We herein report the results of our experience with these procedures in children with end-stage liver disease and/or subsequent end-stage renal disease. Between 1984 and 1995, 12 LTx recipients received 15 kidney allografts. Eight simultaneous and seven sequential LTx/KTx were performed. There were six males and six females, with a mean age of 10.9 years (1.5-23.7). One of the eight simultaneous LTx/KTx was part of a multivisceral allograft. Five KTx were performed at varied intervals after successful LTx, one KTx was performed after a previous simultaneous LTx/KTx, and one KTx was performed after previous sequential LTx/KTx. Immunosuppression was with tacrolimus or cyclosporine and steroids. Indications for LTx were oxalosis (four), congenital hepatic fibrosis (two), cystinosis (one), polycystic liver disease (one), A-1-A deficiency (one), Total Parenteral Nutrition (TPN)-related (one), cryptogenic cirrhosis (one), and hepatoblastoma (one). Indications for KTx were oxalosis (four), drug-induced (four), polycystic kidney disease (three), cystinosis (one), and glomerulonephritis (1). With a mean follow-up of 58 months (0.9-130), the overall patient survival rate was 58% (7/12). One-year and 5-year actuarial patient survival rates were 66% and 58%, respectively. Patient survival rates at 1 year after KTx according to United Network of Organ Sharing (liver) status were 100% for status 3, 50% for status 2, and 0% for status 1. The overall renal allograft survival rate was 47%. Actuarial renal allograft survival rates were 53% at 1 and 5 years. The overall hepatic allograft survival rate was equivalent to the overall patient survival rate (58%). Six of seven surviving patients have normal renal allograft function, and one patient has moderate chronic allograft nephropathy. All surviving patients have normal hepatic allograft function. Six

    Full Text Available Hypophosphatemia has been described in patients undergoing right hepatectomy for liver cancer and in living donors for liver transplantation who also received total parenteral nutrition. At the study centre, significant hypophosphatemia (0.36 mmol/L or less requiring intravenous replacement was seen in two of the first nine living donors for adult-to-adult liver transplantation. To determine the frequency of hypophosphatemia in living donors, the authors obtained phosphate levels on stored serum samples from postoperative days 0, 1, 3 and 7 in all nine patients, none of whom were on total parenteral nutrition. Within the first week, hypophosphatemia developed in 55.6% of patients and phosphate levels returned to normal by day 7 in all nine patients. One patient had normal phosphate levels during the first week, but had profound hypophosphatemia (0.32 mmol/L on day 14 when he presented with a Staphylococcus aureus infection of a bile collection and significant hypoxemia. The extent of hepatectomy and the rate of liver regeneration, estimated by baseline and postoperative day 7 volumetric computed tomography scans, did not correlate with the development of hypophosphatemia. In conclusion, hypophosphatemia is common in living donors undergoing right hepatectomy and may be associated with complications. All living donors should be monitored for the development of hypophosphatemia during the first two postoperative weeks.

    Summary Background: Gamma-aminobutyric acid (GABA) is found throughout the body. The regulation of GABA receptor (GABAR) reduces oxidative stress (OS). Ischemia/reperfusion injury after orthotopic liver transplantation (OLT) causes OS-induced graft damage. The effects of GABAR regulation in donors in vivo were investigated. Material/Methods: Donor rats received saline, a GABAR agonist or GABAR antagonist 4 h before surgery. Recipient rats were divided into four groups according to the donor treatments: laparotomy, OLT with saline, OLT with GABAR agonist and OLT with GABAR antagonist. Histopathological, biochemical and immunohistological examinations were performed at 6, 12 and 24 h after OLT. Protein assays were performed at 6 h after OLT. The 4-hydroxynonenal (4-HNE), ataxia-telangiectasia mutated kinase (ATM), phosphorylated histone H2AX (γH2AX), phosphatidylinositol-3 kinase (PI3K), Akt and superoxide dismutase (SOD) were assessed by western blot analysis. Results: In the univariate analysis, histopathological and biochemical profiles verified that the GABAR agonist reduced graft damage. Immunohistology revealed that the GABAR agonist prevented the induction of apoptosis. Measurement of 4-4-HNE levels confirmed OS-induced damage after OLT, and the GABAR agonist improved this damage. In the γH2AX, PI3K, Akt and antioxidant enzymes (SODs), ATM and H2AX were greatly increased after OLT, and were reduced by the GABAR agonist. In the multivariate analyses between multiple groups, histopathological assessment, aspartate aminotransferase level, immunohistological examinations for apoptotic induction and γH2AX showed statistical differences. Conclusions: A specific agonist demonstrated regulation of GABAR in vivo in the liver. This activation in vivo reduced OS after OLT via the ATM/H2AX pathway. PMID:23792534

    Liver transplantation is currently the standard of care for patients with end stage liver disease. However due to the cadaveric organ shortage, live donor liver transplantation (LDLT), has been recently introduced as a potential solution. We analyzed and support our initial experience with this procedure at USC. From September 1998 until July 2000, a total of 27 patients underwent LDLT at USC University Hospital and Los Angeles Children's Hospital. There were 12 children with the median age of 10 months (4-114) and 15 adults with the median age of 56 years (35-65). The most common indication for transplantation was biliary atresia for children and hepatitis C for adults. All donors did well postoperatively; the median postoperative stay was five days (5-7) for left lateral segmentectomy and seven days (4-12) for lobar donation. None of the donors required blood transfusion, re-operation or postoperative invasive procedure. However, five of them (18%) experienced minor complications. The survival rate in pediatric patients was 100% and only one graft was lost at nine months due to rejection. Two adult recipients died in the postoperative period, one from graft non-function and one from necrotizing fascitis. 37% of adult recipients experienced postoperative complications, mainly related to biliary reconstruction. Also 26% of the recipients underwent reoperation for some of these complications. LDLT is an excellent alternative to cadaveric transplantation with excellent results in the pediatric population. However, in adult patients it still carries a significant complication rate and it should be used with caution.

    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. Case series survey. Tertiary care, major university teaching hospital. 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. 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. Survival and postoperative complications, with the effectiveness of erythropoietin and plateletpheresis as secondary measures. 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. Platelet-pheresis 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 during the same period who met the same restrictive guidelines (P blood products is possible

    Full Text Available Background. Factors affecting outcomes after orthotopic liver transplantation (OLT for hepatocellular carcinoma (HCC have been extensively studied, but some of them have only recently been discovered or reassessed. Methods. We analyzed classical and more recently emerging variables with a hypothetical impact on recurrence-free survival (RFS in a single-center series of 283 patients transplanted for HCC between 1997 and 2009. Results. Five-year patient survival and RFS were 75% and 86%, respectively. Thirty-four (12% patients had HCC recurrence. Elevated preoperative alpha-fetoprotein (AFP levels, preoperative treatments of HCC, unfulfilled Milan and up-to-seven criteria at final histology, poor tumor differentiation, and tumor microvascular invasion negatively affected RFS by univariate analysis. Milan and up-to-seven criteria applied preoperatively, and the use of m-TOR inhibitors did not reach statistical significance. Cox's proportional hazard model showed that only elevated AFP levels (Odds Ratio=2.88; 95% C.I.=1.43–5.80; =.003, preoperative tumor treatments (Odds Ratio=4.84; 95% C.I.=1.42–16.42; =.01, and microvascular invasion (Odds Ratio=4.82; 95% C.I.=1.87–12.41; =.001 were predictors of lower RFS. Conclusions. Biological aggressiveness and preoperative tumor treatment, rather than traditional and expanded dimensional criteria, conditioned the outcomes in patients transplanted for HCC.

    Organ offers in liver transplantation are high-risk medical decisions with a low certainty of whether a better liver offer will come along before death. We hypothesized that decision support could improve the decision to accept or decline. With data from the Scientific Registry of Transplant Recipients, survival models were constructed for 42,857 waiting-list patients and 28,653 posttransplant patients from 2002 to 2008. Daily covariate-adjusted survival probabilities from these 2 models were combined into a 5-year area under the curve to create an individualized prediction of whether an organ offer should be accepted for a given patient. Among 650,832 organ offers from 2008 to 2013, patient survival was compared by whether the clinical decision was concordant or discordant with model predictions. The acceptance benefit (AB)--the predicted gain or loss of life by accepting a given organ versus waiting for the next organ--ranged from 3 to -22 years (harm) and varied geographically; for example, the average benefit of accepting a donation after cardiac death organ ranged from 0.47 to -0.71 years by donation service area. Among organ offers, even when AB was >1 year, the offer was only accepted 10% of the time. Patient survival from the time of the organ offer was better if the model recommendations and the clinical decision were concordant: for offers with AB > 0, the 3-year survival was 80% if the offer was accepted and 66% if it was declined (P decision support may improve patient survival in liver transplantation. © 2015 American Association for the Study of Liver Diseases.

    Full Text Available Aim of the study was to evaluate patient and graft survival after liver transplantation (LT and to determine if primary disease diagnosis, early graft dysfunction or other factors affect it. Furthermore, we analyzed the reasonsof short-term and long-term deaths or retransplantations.Materials and methods. 192 LTs from donors with brain death were performed from December 2004 until June 2014. Recipient age varied from 5 to 71 years. Most frequent diagnosis was liver cirrhosis (mainly due to hepatitis C, then hepatocellular carcinoma (HCC, liver graft dysfunction, etc.Results and discussion. 1-year patient survival is 89.5%, graft survival is 87.7%, 3-year –87% and 84.6%, respectively, and 5-year – 83.5% and 83.0%, respectively. Early mortality (in fi rst 30 days after transplantation was 8%, long-term mortality – 5.9%. Primary non-function graft (PNF was the reason of 66.7% early deaths. In the long term, infections and oncology were the reasons of death with the same frequency – 36.4%. Early graft dysfunction including primary non-function signifi cantly decreases short term survival (p = 0.0002. Nevertheless, in the majority of cases graft function improves and doesn’t affect survival. Donor factors play role in outcomes: early dysfunction is higher (40.6% in extended criteria donor group than in standard donor group (р = 0.0431. PNF has the same trend – 8.5% and 0.0%, respectively, but without signifi cance (р =0.0835. 5-year survival is remarkably lower in HCC group 40.8% (p = 0.003 than in other groups.Conclusion: survival after liver transplantation in our Center is comparable with the results of the world’s centers.

    Full Text Available Liver or hepatic transplantation (LT is the replacement of a diseased liver with part or whole healthy liver from another person (allograft. Human liver transplants were first performed by Thomas Starzl in the United States and Roy Calne in Cambridge, England in 1963 and 1967, respectively. Liver transplantation is a viable treatment option for end-stage liver disease and acute liver failure. Pediatric patients account for about 12.5% of liver transplant recipients. The most commonly used technique is orthotopic transplantation, in which the native liver is removed and replaced by the donor organ in the same anatomic location as the original liver. Cirrhosis, or liver injury, is a common reason why adults need liver transplants and children with bile duct disease issues are often the candidates. Survival statistics depend greatly on the age of donor, age of recipient, skill of the transplant center, compliance of the recipient, whether the organ came from a living or cadaveric donor and overall health of the recipient. Survival rates improve almost yearly, due to improved techniques and medications.

    Full Text Available Objective: to optimize procedures to maintain minute circulation volume at different stages of orthotopic liver transplantation. Subjects and methods. In the period 2005—2010, Sverdlovsk Regional Clinical Hospital One performed 32 orthotopic liver transplantations, including one retransplantation. The patients’ ASA class was (4—5. The operations were carried out under general anesthesia. The mean duration of surgery was 8.1 (range 5.8—10.5 hours. The investigators applied anesthesia based on iso-fluorane 0.6—0.9 MAC (by monitoring the anesthesia depth index with cerebral state index (CSI-40-60, as well as extended central hemodynamic monitoring (prepulmonary hemodilution. All the operations were made via portofemoroaxillary bypass, by using a centrifugal Biopump. Eight surgical stages were identified: 1 run-in (after tracheal intubation; 2 liver mobilization; 3 partial bypass; 4 complete bypass (hepatectomy, a liver-free period; 5 reperfusion; 6 a postreperfusion period (bypass end; 7 biliary repair; 8 the end of an operation. The concentrations of blood parameters, electrolytes, acid-base balance, and the levels of lactate and glucose were examined. The data were processed statistically. Central hemodynamics was monitored by prepulmonary thermodilution, by calculating cardiac index (CI, stroke index, and total peripheral vascular resistance index (TPVRI at the stages: liver mobilization, postreperfusion period (bypass end, and the end of surgery. Results. Even during partial bypass, there was a significant drop in mean blood pressure (MBP as compared to the baseline levels (p<0.05. Reperfusion was also accompanied by a significant decrease in MBP and an increase in heart rate. At the end of reperfusion and in the postreperfusion period, TPVRI was halved (689.2±68.0 as compared to the baseline levels. In the postreperfusion period, central venous and pulmonary artery pressures were significantly increased by 32 and 21%, respectively

    Full Text Available Clostridium difficile infection (CDI represents one of the most common healthcare-associated infections. Due to increasing numbers of recurrences and therapy failures, CDI has become a major disease burden. Studies have shown that fecal microbiota transplantation (FMT can both be a safe and highly efficacious therapy for patients with therapy-refractory CDI. However, patients undergoing solid organ transplantation are at high risk for CDI due to long-term immunosuppression, previous antibiotic therapy, and proton pump inhibitor use. Additionally, these patients may be especially prone to adverse events related to FMT. Here, we report a successful FMT in a patient with severe therapy-refractory CDI after liver transplantation.

    Heme-Oxygenase-1 catalyzes hemoglobin into bilirubin, iron, and carbon monoxide, a well known vasodilator. Heme-Oxygenase-1 expression and carbon monoxide production as measured by blood carboxyhemoglobin levels, increase in end stage liver disease patients. We hypothesized that there may be a correlation between carboxyhemoglobin level and early graft function in patients undergoing liver transplant surgeries. In a descriptive retrospective study, 39 patients who underwent liver transplantation between the year 2005 and 2006 at KFSH&RC, are included in the study. All patients received general anesthesia with isoflurane in 50% oxygen and air. Levels of oxyhemoglobin, carboxyhemoglobin and methemoglobin concentration in percentage were recorded at preoperative time, anhepatic phase, end of surgery, ICU admission and 24 hr after surgery. The level of lactic acid, prothrombin time (PT), partial thrombin time (PTT), serum total bilirubin and ammonia were also recorded at ICU admission and 24 hr after surgery. The numbers of blood units transfused were recorded. 39 patients were included in the study with 13/39 for living donor liver transplant (LDLT) compared to 26/39 patients scheduled for deceased donor liver transplant (DDLT). The mean age was 35.9 +/- 16.9 years while the mean body weight was 60.3 +/- 20.9 Kg. Female to male ratio was 21/18. The median packed red blood cell (PRBC) units was 4 (Rang 0-40). There was a significant increase in carboxyhemoglobin level during the anhepatic phase, end of surgery and on ICU admission compared with preoperative value (pcarboxyhemoglobin level on ICU admission and 24 hrs postoperatively were positively correlated with the changes in serum total bilirubin and prothrombin time (R = 0.35, 0.382, 0.325 and 0.31) respectively pcarboxyhemoglobin concentration and PT and total bilirubin while still the correlation with lactic acid was weak.

    Malnutrition is found in almost 100% of patients with end stage liver disease (ESLD) awaiting transplantation and malnutrition before transplantation leads to higher rates of post-transplant complications and worse graft survival outcomes. Reasons for protein energy malnutrition include several metabolic alterations such as inadequate intake, malabsorption, and overloaded expenditure. And also, stress from surgery, gastrointestinal reperfusion injury, immunosuppressive therapy and corticosteriods use lead to delayed bowl function recovery and disorder of nutrients absorption. In the pretransplant phase, nutritional goals include optimization of nutritional status and treatment of nutrition-related symptoms induced by hepatic decompensation. During the acute post-transplant phase, adequate nutrition is required to help support metabolic demands, replenish lost stores, prevent infection, arrive at a new immunologic balance, and promote overall recovery. In a word, it is extremely important to identify and correct nutritional deficiencies in this population and provide an adequate nutritional support during all phases of liver transplantation (LT). This study review focuses on prevalence, nutrition support, evaluation, and management of perioperative nutrition disorder in patients with ESLD undergoing LT.

    Sirolimus is an immunosuppressive drug that has been used during the past few years. Sirolimus is indicated in rescue therapies and to reduce the secondary toxic effects of calcineurin inhibitors. This drug has been associated with infrequent but severe pulmonary toxicity. Cases of interstitial pneumonitis, bronchiolitis obliterans with organizing pneumonia, and alveolar proteinosis have been described. We describe a case of pulmonary toxicity associated with the use of sirolimus in a 59-yr-old liver transplant recipient. We also review all reported cases of sirolimus-associated lung toxicity among liver transplantation recipients, with the intention of understanding the risk factors, the clinical picture and the outcomes of this complication. Five cases have been reported since January 2000, including the present case. Clinical presentation is similar, with fever, dyspnoea, fatigue, cough, and hemoptysis. Discontinuation of the drug led to resolution of clinical and radiographic findings. Sirolimus-induced pulmonary toxicity is a serious condition and should be considered in the differential diagnosis of liver recipients presenting with respiratory findings. Discontinuation of the drug is associated with resolution of the pulmonary compromise

    Hepatitis C virus (HCV)-induced cirrhosis is the major indication for liver transplantation globally, and an increasing indication for liver transplantation in Sweden. We have retrospectively examined the 120 patients transplanted for HCV cirrhosis from 1987 through 2005, including 11 who received more than one graft. The 1-, 3-, and 5-year postoperative survivals for all patients transplanted for HCV with or without hepatocellular cancer (HCC) were 77%, 66%, and 53%, respectively. HCV patients without HCC had a 1-, 3-, and 5-year survivals of 78%, 73%, and 61%, compared with 84%, 79% and 74%, respectively, for patients transplanted with chronic liver diseases without cancer or HCV. The number of patients with HCV cirrhosis transplanted in our center is increasing. Compared with patients transplanted for other chronic liver diseases, we experienced inferior results among patients with HCV cirrhosis.

HCC is the sixth most common cancer around the world, and leading cause of death among cirrhotic patients. Diagnosis is based upon radiological characteristics and rarely biopsy results; the Barcelona Clinic Liver Cancer staging system is the most used guideline for treatment. With several treatment options available transplantation and resection continue to be the major curative therapeutic option for this patients. However treatment must be individualized to each patient to improve recurrences and outcomes. The aim of this paper is to review the present role of liver transplantation in the management of hepatocarcinoma. Resumen: El trasplante hepático es el estándar de oro en el tratamiento de enfermedad hepática avanzada, incluyendo pacientes cirróticos que han desarrollado hepatocarcinoma pero que se encuentran dentro de los criterios de Milán.

    Population-based evidence of the relative risk of cancer among heart, kidney, and liver transplant recipients from Asia is lacking. The Taiwan National Health Insurance Research Database was used to conduct a population-based cohort study of transplant recipients (n = 5396), comprising 801 heart, 2847 kidney, and 1748 liver transplant recipients between 2001 and 2012. Standardized incidence ratios and Cox regression models were used. Compared with the general population, the risk of cancer increased 3.8-fold after heart transplantation, 4.1-fold after kidney transplantation and 4.6-fold after liver transplantation. Cancer occurrence showed considerable variation according to transplanted organs. The most common cancers in all transplant patients were cancers of the head and neck, liver, bladder, and kidney and non-Hodgkin lymphoma. Male recipients had an increased risk of cancers of the head and neck and liver, and female kidney recipients had a significant risk of bladder and kidney cancer. The adjusted hazard ratio for any cancer in all recipients was higher in liver transplant recipients compared with that in heart transplant recipients (hazard ratio = 1.5, P = .04). Cancer occurrence varied considerably and posttransplant cancer screening should be performed routinely according to transplanted organ and sex.

    Full Text Available Abstract Objective Liver injury due to trauma is a rare indication for transplantation. The main indications in such cases were uncontrollable bleeding and insufficient hepatic function. Because of poor results, liver transplantation in these patients is occasionally described as "waste of organs", however based on insufficient data. This study aims to report our experience and to critically question the indication of transplantation in these patients. Methods All liver transplantations at our institution were reviewed retrospectively. This covered 1,529 liver transplants between September 1987 and December 2008. Of them, 6 transplants were performed due to motor-vehicle accidents which caused uncontrollable acute liver trauma in 4 patients. The patients' peri-operative course, short- and long-term outcomes were analyzed. Results Five deceased-donor liver transplantations (4 full size, 1 split and 1 living donor (right transplantation were performed. The median GCS score was 9/15; the median MELD score was 15. Postoperative complications were observed in 3 patients, requiring re-operation in 2. After a median (range follow-up of 32.95 (10.3-55.6 months, 2 patients are alive and remain well on immunosuppression. Conclusion Liver transplantation in patients with otherwise surgically uncontrollable acute liver injury can be indicated as a life saving procedure and can be performed successfully in highly selected cases.

    Full Text Available Zygomycosis is an increasing threat to patients with human immunodeficiency virus (HIV infection. Zygomycosis (formerly called mucormycosis is the fungal infection with Mucor, Rhizopus, or other species that share a common morphology of large empty pauciseptate hyphae with rare random-angle branching and a collapsed “twisted ribbon” appearance. Morphology allows a specific diagnosis on frozen section or smear prior to growth and identification of the fungi in culture which makes it improtant because treatment is different than that for more common mycoses such as candidiasis and aspergillosis. We present an informative and illustrative case of zygomycosis in a patient with HIV infection and liver transplantation.

    Full Text Available AimThe present study aimed to evaluate the change in quality of life 12 months following liver transplantation in patients with Familial Amyloid Polyneuropathy (FAP.MethodIn this study 150 transplant candidates, attending the outpatient clinic of a Liver Transplantation Centre in Lisbon, were assessed between March 1, 2006 and December 1, 2007. From these, 84 were transplanted, and 62 finished the study; 20 with FAP and 42 with Liver Disease (LD. These patients were assessed before, and 12 months after, transplantation. The patients that remained waiting for transplantation originated the control group. First, transplanted (study group and non-transplanted (control group patients were compared regardless of their diagnosis, and then only FAP patients were compared between both groups.Results12 months after transplantation the score on the Quality of Life’s Physical and Mental Component of the SF-36 was significantly higher in transplanted versus non-transplanted patients (concerning the whole group FAP and LD patients. However, significant differences were only found for the Quality of Life’s Physical Component subscale between both FAP groups (study and control group.ConclusionIn sum, liver transplantation does not have a significant impact in FAP patients’ Mental Quality of Life score. One possible reason to this is the fail in acquiring adaptive coping strategies after transplantation.

    Islet transplantation is an attractive treatment for patients with insulin-dependent diabetes mellitus, and currently the liver is the favored transplantation site. However, an alternative site is desirable because of the low efficiency of hepatic transplantation, requiring 2-3 donors for a single recipient, and because the transplanted islets cannot be accessed or retrieved. We developed a novel procedure of islet transplantation to the inguinal subcutaneous white adipose tissue (ISWAT) of mice and described functional and morphological characteristics of transplanted syngeneic islets. Also, it was determined whether islet allograft rejection in the ISWAT can be prevented by immunosuppressive agents. Furthermore, it was examined whether human islets function when grafted in this particular site of immune-deficient mice. In this site, transplanted islets are engrafted as clusters and function to reverse STZ-induced diabetes in mice. Importantly, transplanted islets can be visualized by CT and are easily retrievable, and allograft rejection is preventable by blockade of co-stimulatory signals. Of much importance, the efficiency of islet transplantation in this site is superior to the liver, in which hyperglycemia of diabetic recipient mice is ameliorated after transplantation of 200 syngeneic islets (the islet number yielded from 1 mouse pancreas) to the ISWAT but not to the liver. Furthermore, human islets transplanted in this particular site function to reverse diabetes in immune-deficient mice. Thus, the ISWAT is superior to the liver as the site of islet transplantation, which may lead to improved outcome of clinical islet transplantation.

    Full Text Available We describe a 14-year-old girl, who was 13 y after liver transplantation for biliary atresia with an unremarkable postoperative course. She presented with fever of up to 40°C, extreme fatigue, malaise, anorexia, and occasional vomiting. On physical examination the only finding was splenomegaly. Lab results showed hyperglobulinemia and an elevated sedimentation rate. Liver function tests were normal except for mild elevation of γGTP. Abdominal U/S and CT demonstrated an enlarged spleen with retroperitoneal and mesenteric lymph nodes enlargement. An exhaustive evaluation for infectious causes, autoimmune conditions, and malignancy was negative. A full recovery after 5 months prompted testing for self-limited infectious etiologies. Yersinia enterocolitica infection was diagnosed.

    Orthotopic liver transplant (OLTx) has evolved to a successful surgical management for end-stage liver diseases. Awareness and information about OLTx is an important tool in assisting OLTx recipients and people supporting them, including non-transplant clinicians. The study aimed to investigate the nature and quality of liver transplant-related patient information on the World Wide Web. Four common search engines were used to explore the Internet by using the key words 'Liver transplant'. The URL (unique resource locator) of the top 50 returns was chosen as it was judged unlikely that the average user would search beyond the first 50 sites returned by a given search. Each Web site was assessed on the following categories: origin, language, accessibility and extent of the information. A weighted Information Score (IS) was created to assess the quality of clinical and educational value of each Web site and was scored independently by three transplant clinicians. The Internet search performed with the aid of the four search engines yielded a total of 2,255,244 Web sites. Of the 200 possible sites, only 58 Web sites were assessed because of repetition of the same Web sites and non-accessible links. The overall median weighted IS was 22 (IQR 1 - 42). Of the 58 Web sites analysed, 45 (77%) belonged to USA, six (10%) were European, and seven (12%) were from the rest of the world. The median weighted IS of publications originating from Europe and USA was 40 (IQR = 22 - 60) and 23 (IQR = 6 - 38), respectively. Although European Web sites produced a higher weighted IS [40 (IQR = 22 - 60)] as compared with the USA publications [23 (IQR = 6 - 38)], this was not statistically significant (p = 0.07). Web sites belonging to the academic institutions and the professional organizations scored significantly higher with a median weighted IS of 28 (IQR = 16 - 44) and 24(12 - 35), respectively, as compared with the commercial Web sites (median = 6 with IQR of 0 - 14, p = .001).

    A wide variety of pulmonary conditions are found in cirrhotic patients and may compromise the pleura, diaphragm, parenchyma, and pulmonary vasculature, influencing the results of liver transplantation. To evaluate the pulmonary function (lung capacities, volumes, and gasometric study) of patients with liver cirrhosis awaiting liver transplantation. Cirrhotic patients, subdivided into 3 groups stratified by liver disease severity using the Child-Pugh-Turcotte score, were compared with a control group of healthy volunteers. In spirometry, the parameters evaluated were total lung capacity, forced volume in the first second, and the relationship between forced volume in the first minute and forced vital capacity. Blood gas analysis was performed. In the control group, arterial oxygenation was evaluated by peripheral oxygen saturation by pulse oximetry. Of the 55 patients (75% men, 51 ± 12.77 years), 11 were Child A (73% men, 52 ± 14.01 years), 23 were Child B (75% men, 51 ± 12.77 years), and 21 were Child C (95% men, 50 ± 12.09 years). The control group had 20 individuals (50% men, 47 ± 8.15 years). Pulmonary capacities and volumes by the parameters evaluated were within the normal range. Arterial blood gas analysis detected no hypoxemia, but a tendency to low partial gas pressure was noted. In this population of cirrhotic patients the parameters of spirometry were normal in relation to the lung capacities and volumes in the different groups. No hypoxemia was detected, but a tendency to hypocapnia in the blood gas was noted. Copyright © 2018. Published by Elsevier Inc.

    Background Acute liver failure is associated with a high mortality rate and the main purposes of treatment are to prevent cerebral edema and infections, which often are responsible for patient death. The orthotopic liver transplantation is the gold standard treatment and improves the 1-year survival. Aim To describe an alternative technique to auxiliary liver transplant on acute liver failure. Method Was performed whole auxiliary liver transplantation as an alternative technique for a partial auxiliary liver transplantation using a whole liver graft from a child removing the native right liver performed a right hepatectomy. The patient met the O´Grady´s criteria and the rational to indicate an auxiliary orthotopic liver transplantation was the acute classification without hemodynamic instability or renal failure in a patient with deterioration in consciousness. Results The procedure improved liver function and decreased intracranial hypertension in the postoperative period. Conclusion This technique can overcome some postoperative complications that are associated with partial grafts. As far as is known, this is the first case of auxiliary orthotopic liver transplantation in Brazil. PMID:26176253

    Living donor liver transplantation (LDLT) has emerged as an alternative to deceased donor liver transplantation (DDLT) because of the increasing number of patients waiting for liver transplantation (LT). However, whether it can achieve operative outcomes similar to those achieved with DDLT for adult patients remains controversial. We conducted this meta-analysis to compare the operative outcomes of LDLT and DDLT recipients. A literature search was performed to identify clinical controlled studies comparing LDLT and DDLT that were published before October 2013. Four perioperative outcomes [duration of the recipient operation (DRO), red blood cell (RBC) transfusion requirement, length of the hospital stay, and cold ischemia time (CIT)] and 5 postoperative complication outcomes (biliary complications, vascular complications, intra-abdominal bleeding, perioperative death, and retransplantation) were the main outcomes assessed. Nineteen studies with a total of 5450 patients were included in the meta-analysis. In comparison with DDLT, LDLT was associated with a significantly longer DRO and a shorter CIT. We found that biliary complications [odds ratio (OR) = 3.08, 95% confidence interval (CI) = 1.97-4.81, P < 0.001], vascular complications (OR = 2.16, 95% CI = 1.32-3.54, P = 0.002), and retransplantation (OR = 1.76, 95% CI = 1.09-2.83, P = 0.02) occurred more frequently for LDLT recipients, and the subgroup analysis indicated that the biliary complication rate decreased dramatically with greater LDLT experience. No significant difference was observed in RBC transfusion requirements, the lengths of hospital stays, intra-abdominal bleeding rates, or perioperative mortality between LDLT and DDLT recipients. In conclusion, LDLT is associated with a higher rate of surgical complications after transplantation. A reduction of postoperative complication rates can be achieved as centers gain greater experience with LDLT. However, LDLT is still

    Immediate postoperative tracheal extubation (IPTE) is one of the most important subject in recovery after surgery (ERAS) for liver transplantation. However, the criteria for IPTE is not uniform at present. We reported a successful IPTE in a liver transplant recipient with encephalopathy and a high Mayo end-stage liver disease (MELD) score of 41, which beyond the so-called criteria reported in the literature. The patient was 48-year-old man, admitted in September 2016 for end-stage liver cirrhosis secondary to hepatitis B. End-stage liver cirrhosis secondary to hepatitis B with encephalopathy and a high MELD score of 41. He was involved in our ERAS project and was extubated at the end of the liver transplantation in the operating room. As a result, the patient was not reintubated and had an excellent postoperative recovery, staying in intensive care unit (ICU) for just 2 days and discharged home on day 10. We believed IPTE in liver transplant recipients with severe liver dysfunction is a meaningful challenge in ERAS for liver transplantation. Our case and literature review suggest 3 things: IPTE in liver transplantation is generally feasible and safe; the encephalopathy or high MELD score should not be the only limiting factor; and a more systematic predicting system for IPTE in liver transplantation should be addressed in future studies.

    Introduction: Main purpose of our study is to demonstrate the spectral and color Doppler ultrasonography (DUS) findings that would indicate hepatic artery stenosis (HAS) after liver transplantation and to report our single center results. Moreover we want to establish role and limits of the different imaging techniques in detecting HAS, proposing a non invasive diagnostic approach and to depict indications and feasibility of endovascular treatment in the single patient. Materials and methods: Our study consisted of 222 patients who underwent liver transplantation between January 1999 and December 2009. DUS findings were correlated with multidetector computed tomography angiography (MDCTA) and angiographic results. Results: HAS occurred in 21 cases (9.5%). In all cases diagnosis was performed by DUS. MDCTA quantified stenosis and showed an overall picture of splanchnic vascularization. Based on DUS and MDCTA data integration, in 9 cases we adopted the “wait and see” strategy. Moreover in 12 cases treatment was considered necessary. For hepatic artery stenosis, use of DUS criteria resulted in a sensitivity of 100% (20/20), a specificity of 99.5% (201/202), a positive predictive value (PPV) of 95% (20/21), and negative predictive value (NPV) of 100% (201/201), and an overall accuracy of 99.5% (221/222). Conclusion: Our study underline the role of DUS in early diagnosis of HAS: repeated evaluation of both direct and indirect signs increases NPV and sensitivity of DUS.

    We analyze our experience with the management of biliary strictures (BSs) in 27 pediatric patients who underwent liver transplantation with the diagnosis of BS. Mean recipient age was 38 months (range, 2.5-182 months). In all patients percutaneous transhepatic cholangiography, biliary catheter placement, and bilioplasty were performed. In 20 patients the stenoses were judged resolved by percutaneous balloon dilatation and the catheters removed. Mean number of balloon dilatations performed was 4.1 (range, 3-6). No major complications occurred. All 20 patients are symptom-free with respect to BS at a mean follow-up of 13 months (range, 2-46 months). In 15 of 20 patients (75%) one course of percutaneous stenting and bilioplasty was performed, with no evidence of recurrence of BS at a mean follow-up of 15 months (range, 2-46 months). In 4 of 20 patients (20%) two courses of percutaneous stenting and bilioplasty were performed; the mean time to recurrence was 9.8 months (range, 2.4-24 months). There was no evidence of recurrence of BS at a mean follow-up of 12 months (range, 2-16 months). In 1 of 20 patients (5%) three courses of percutaneous stenting and bilioplasty were performed; there was no evidence of recurrence of BS at a mean follow-up of 10 months. In conclusion, BS is a major problem following pediatric liver transplantation. Radiological percutaneous treatment is safe and effective, avoiding, in most cases, surgical revision of the anastomosis.

  2. [Strategies for avoiding hepatitis B infection recurrence following liver transplantation].

    2014-07-01

    Hepatitis B is currently an excellent indication for liver transplantation due to the highly effective strategies of prophylaxis and treatment for recurrent hepatitis B infection. The combined administration of low-dose hepatitis B hyperimmune gamma globulin and a nucleoside/nucleotide analogue with a high genetic barrier to resistance, such as entecavir (except for patients with lamivudine resistance) or tenofovir, represents the standard for the prophylaxis of recurrent hepatitis B infection and is used in most centers. The drawbacks of long-term administration of hyperimmune gamma globulin have led to research on regimens in which this agent is withdrawn after a certain amount of time in combination treatment, a strategy that appears to be safe in patients with undetectable viremia at the time of liver transplantation if the patients adhere to the treatment. In recent years, there has also been research into regimens of gamma-globulin-free prophylaxis, based only on the administration of oral antiviral drugs, which appear to be safe if antivirals with a high genetic barrier to resistance are used. Hepatitis B prophylaxis should be maintained indefinitely; therefore, the total withdrawal of prophylaxis is not an accepted strategy at present in daily clinical practice if not in the context of a clinical trial.

    Background. Small volumes of fluid in the pleural and peritoneal cavities are common after paediatric liver transplantation. Occasionally, larger fluid collections develop and need intervention by aspiration or insertion of a drain. Objective. To assess the incidence of moderate and large pleural and peritoneal fluid collections following paediatric liver transplantation, the need for intervention and the outcome following radiological and non-radiological treatment, with the ultimate objective of recommending a treatment protocol for such post-operative fluid collections. Materials and methods. A total of 184 consecutive liver grafts in 164 children were reviewed. Results. Of 184 grafts, 31 (16.8 %) developed excessive fluid collections requiring intervention (19 pleural effusions, 8 ascites and 4 effusions and ascites). The effusions were first diagnosed between days 1 and 44 after transplant and the ascites between days 1 and 14. The initial diagnosis was made radiologically in 21 (91 %) of 23 pleural effusions and in 10 (83 %) of 12 ascites. No identifiable cause or association was seen in 18 (58 %) of 31 cases. The mean duration of the pleural effusions and ascites, from onset of treatment to resolution, ranged from 33 {+-} 42 days (SD) to 35 {+-} 48 days and from 36 {+-} 47 days to 39 {+-} 46 days respectively. Comparison of the modes of interventional treatment (i. e. unguided, radiological and surgical) showed no statistically significant difference in the outcome of the management. Conclusions. Post-transplantation pleural effusions and ascites requiring intervention are often without definite cause. They are more common with reduced grafts, but this cannot completely explain the occurrence or the protracted duration of accumulation in spite of combined interventional management. The outcome of treatment is not significantly influenced by the mode of intervention except in cases where surgical intervention is indicated. Patients could be managed

    2008-03-01

    Full Text Available Herpes simplex infection is characterized by acute or subacute infection, often followed by a chronic carrier state. Consecutive recurrences may flare up if immunocompromise occurs. Herpes simplex associated esophagitis or duodenal ulcer have been reported in immunocompromised patients due to neoplasm, HIV/AIDS or therapeutically induced immune deficiency. Here we report the case of an HSV-DNA seronegative patient who developed grade III dysphagia 13 days after allogeneic liver transplantation. Endoscopy revealed an esophageal-gastric ulcer, and biopsy histopathology showed a distinct fibroplastic and capillary ulcer pattern highly suspicious for viral infection. Immunohistochemistry staining revealed a distinct nuclear positive anti-HSV reaction. Antiviral therapy with acyclovir and high-dose PPI led to a complete revision of clinical symptoms within 48 h. Repeat control endoscopy after 7 days showed complete healing of the former ulcer site at the gastroesophageal junction. Although the incidence of post-transplantation Herpes simplex induced gastroesophageal disease is low, the viral HSV ulcer may be included into a differential diagnosis if dysphagia occurs after transplantation even if HSV-DNA PCR is negative.

    Full Text Available Objective: to determine the prevalence of abnormal total cholesterol (TC, low density lipoprotein (LDL, high density lipoprotein (HDL and triglycerides in patients undergoing liver transplantation (LTx and to identify predictors of these disorders. Methods: cross-sectional study to assess the prevalence of dyslipidemia in patients undergoing LTx. Demographic, socioeconomic, clinical, anthropometric and dietetic data were collected to determine the association with dyslipidemia using univariate and multivariate statistical analysis. Results: 136 patients were evaluated, 68.1% of which had at least one type of dyslipidemia. The triglyceride level was high in 32.4% of cases, with low HDL in 49.3% of patients and high LDL levels in only 8.8%. High total cholesterol was observed in 16.2% of the study population and was associated with the recommendation for transplantation due to ethanolic cirrhosis (OR = 2.7 and a greater number of hours slept per night (OR = 1.5. Conclusion: many patients presented dyslipidemia after transplantation, demonstrating the need for interventions in relation to modifiable factors associated with dyslipidemias that can mitigate or prevent these disorders.

    Purpose: Analysis of the course of disease in patients with histologically proven HCC before and after orthotopic liver transplantation (LTx) who received transarterial chemoembolization (TACE). Material and Methods: Thirty-five of a total collective of 363 patients with histologically proven HCC underwent LTx. Before LTx, all patients were treated with sequential TACE. According to treatment pattern, TACE should be performed every 6 weeks, using a suspension consisting of max. 10 mg Mitomycin C as well as 10-30 ml iodized oil (Lipiodol). Patients were classified according to the Milano criteria. Criteria were called exceeded if the tumor size was >5 cm and/or >3 tumors larger than 3 cm were found. Therapy success and liver function were examined by means of spiral CT and laboratory controls. Investigation parameters included the number of tumor knots as well as the maximum tumor size. Additionally, the Lipiodol accumulation, the patency of the portal vein and the occurrence of complications were checked. Results: Altogether, 184 TACE procedures were accomplished (5.3+/-3.3, range 1-14). The waiting period up to the transplantation amounted to 366+/-255 days (range 44-1137). The average number of tumor knots for each patient was 3.1+/-2.2 before and 2.9+/-2.2 after TACE (p=0.887). The average tumor size was 4.2+/-2.5 before and 2.8+/-1.4 after TACE. The Milano criteria to LTx crossed 17/35 patients. Patients with exceeded Milan criteria showed a highly significant size reduction of the tumor after TACE (p=0.001); in 9/17 cases the transplantation criteria were secondarily fulfilled through downstaging. A successful LTx was accomplished in 35/35 cases. Follow up after LTx was 769+/-509 days. The tumor recurrence in patients with exceeded vs. fulfilled transplantation criteria was 11.1% vs. 11.8% (p=0.99). The recurrence free survival was 93.3%, 82.5% and 82.5% at 1, 3 and 5 years, respectively. There were no relevant differences between patients with exceeded vs

    Objective: To discuss the perioperative nursing norm for patients who are suffering from biliary complications occurred after liver transplantation and who will receive interventional management to treat the complications. Methods: Interventional therapies were performed in 20 patients with biliary complications due to liver transplantation. The interventional procedures performed in 20 cases included percutaneous biliary drainage (n = 13), percutaneous biliary balloon dilatation (n = 5) and biliary stent implantation (n = 7). The clinical results were observed and analyzed. Results: Biliary tract complications occurred after liver transplantation were seen frequently. Proper interventional management could markedly improve the successful rate of liver transplantation and increase the survival rate of the patients. In accordance with the individual condition, proper nursing measures should be taken promptly and effectively. Conclusion: Conscientious and effective nursing can contribute to the early detection of biliary complications and, therefore, to improve the survival rate of both the transplanted liver and the patients.

    Orthotopic liver transplantation is a curative treatment for hepatocellular carcinoma within Milan criteria, but these criteria preclude many patients from transplant candidacy. Recent studies have demonstrated that downstaging therapy can reduce tumor burden to meet conventional criteria. The present study reports a single-center experience with tumor downstaging and its effects on post-orthotopic liver transplantation outcomes. All patients with hepatocellular carcinoma who were evaluated by our multidisciplinary liver services team from 2012 to 2016 were identified (N = 214). Orthotopic liver transplantation candidates presenting outside of Milan criteria at initial radiographic diagnosis and/or an initial alpha-fetoprotein >400 ng/mL were categorized as at high risk for tumor recurrence and post-transplant mortality. Of the 214 patients newly diagnosed with hepatocellular carcinoma, 73 (34.1%) eventually underwent orthotopic liver transplantation. The majority of patients who did not undergo orthotopic liver transplantation were deceased or lost to follow-up (47.5%), with 14 of 141 (9.9%) currently listed for transplantation. Among transplanted patients, 21 of 73 (28.8%) were considered high-risk candidates. All 21 patients were downstaged to within Milan criteria with an alpha-fetoprotein hepatocellular carcinoma was higher but acceptable between downstaged high-risk and traditional candidates (9.5% vs 1.9%; P > .05) at a median follow-up period of 17 months. Downstaged high-risk candidates had a similar overall survival compared with those transplanted within Milan criteria (log-rank P > .05). In highly selected cases, patients with hepatocellular carcinoma outside of traditional criteria for orthotopic liver transplantation may undergo downstaging therapy in a multidisciplinary fashion with excellent post-transplant outcomes. These data support an aggressive downstaging approach for selected patients who would otherwise be deemed ineligible for

    Full Text Available Limited access to or receipt of liver transplantation (LT may jeopardize survival of patients with end-stage liver diseases. Taiwan launched its National Health Insurance (NHI program in 1995, which essentially removes financial barriers to health care. This study aims to investigate where there are still demographic and urbanization disparities of LT after 15 years of NHI program implementation. Data analyzed in this study were retrieved from Taiwan’s NHI inpatient claims. A total of 3020 people aged ≥18 years received LT between 2000 and 2013. We calculated crude and adjusted prevalence rate of LT according to secular year, age, sex, and urbanization. The multiple Poisson regression model was further employed to assess the independent effects of demographics and urbanization on prevalence of LT. The biennial number of people receiving LT substantially increased from 56 in 2000–2001 to 880 in 2012–2013, representing a prevalence rate of 1.63 and 18.58 per 106, respectively. Such increasing secular trend was independent of sex. The prevalence was consistently higher in men than in women. The prevalence also increased with age in people <65 years, but dropped sharply in the elderly (≥65 years people. We noted a significant disparity of LT in areas with different levels of urbanization. Compared to urban areas, satellite (prevalence rate ratio (PRR, 0.63, 95% confidence interval (CI, 0.57–0.69 and rural (PRR, 0.76, 95% CI, 0.69–0.83 areas were both associated with a significantly lower prevalence of LT. There are still significant demographic and urbanization disparities in LT after 15 years of NHI program implementation. Given the predominance of living donor liver transplantation in Taiwan, further studies should be conducted to investigate factors associated with having a potential living donor for LT.

    Immunosuppressive treatment used in pregnant liver recipients may have a negative impact on fetal development and successively a child. The aim of the study was to make a neurological assessment of infants and children born to liver transplant recipients (LTRs) born between December 4, 2001, and February 11, 2013, in the 1(st) Department of Obstetrics and Gynecology, Medical University of Warsaw. The study involved 88 children, of whom 44 children were born to LTR mothers, and 44 children born to women who were not organ recipients and delivered at a similar gestational age. The gestational age of neonates ranged from 33 to 41 weeks, and the birth weight ranged from 1420 g to 4100 g. The neurological examination was performed in children from 7 weeks to 10 years of age. The neurological development was assessed by a specialist in pediatric neurology. The results of the examination were divided according to the following criteria: 1) normal development, 2) slight disorders, 3) moderate disorders, and 4) severe disorders. The Fisher's exact test was used for statistical analysis. Normal development was found in 35 of 44 (79.54%) children in the LTR group and 39 of 44 (88.63%) children in the control group (P = .3827). Slight disorders were observed in 6 of 44 (13.63%) children in LTR group and 5 of 44 (11.36%) children in the control group. Moderate disorders were found only in 3 of 44 (6.81%) children in the LTR group. No severe disorders were observed in both groups. Neurological development of children born to the liver recipients who were exposed to chronic immunosuppressive treatment in their fetal lives is the same as that of children whose mothers have not undergone organ transplantation.

    Organ transplant centers are under increasing scrutiny to maintain outcomes while controlling cost in a challenging population of patients. Throughout health care and transplant specifically, length of stay is used as a benchmark for both quality and resource utilization. To decrease our length of stay for liver transplant by using Lean Six Sigma methods. The Six Sigma DMAIC (Define, Measure, Analyze, Improve, Control) method was used to systematically analyze our process from transplant listing to hospital discharge after transplant, identifying many factors affecting length of stay. Adult, single-organ, primary liver transplant recipients between July 2008 and June 2012 were included in the study. Recipients with living donors or fulminant liver failure were excluded. Multiple interventions, including a clinical pathway and enhanced communication, were implemented. Length of stay after liver transplant and readmission after liver transplant.R ESULTS: Median length of stay decreased significantly from 11 days before the intervention to 8 days after the intervention. Readmission rate did not change throughout the study. The improved length of stay was maintained for 24 months after the study. Using a Lean Six Sigma approach, we were able to significantly decrease the length of stay of liver transplant patients. These results brought our center's outcomes in accordance with our goal and industry benchmark of 8 days. Clear expectations, improved teamwork, and a multidisciplinary clinical pathway were key elements in achieving and maintaining these gains.

    Liver transplantation is an accepted treatment modality in the management of MSUD. To our knowledge, ours is only the second successful case to date of a patient with MSUD receiving an allograft from an RLD who is a heterozygous carrier for the disease. In view of the worldwide shortage of available organs for transplantation, heterozygote to homozygote transplantation in the setting of MSUD may provide a viable alternative for those awaiting transplantation. We report on the case of a two-yr-old infant with MSUD, who received a left lateral segment (segments II and III) liver transplant from his mother, a heterozygote carrier of one of the three abnormal genes implicated in MSUD. Post-operative BCAA levels normalized in our patient and remained so on an unrestricted protein diet and during times of physiological stress. To date, this is only the second case of a successful RLD liver transplant in a child with MSUD. Preliminary results indicate that RLD liver transplants are at least equivalent to deceased donor liver transplants in the treatment of MSUD, although longer term follow-up is required. Heterozygote to homozygote RLD transplant in patients with MSUD presents a new pool of potential liver donors. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

  16. The Role of Humoral Alloreactivity in Liver Transplantation: Lessons Learned and New Perspectives

    2017-01-01

    Full Text Available More than ten years after the initial description of the humoral theory of transplantation by Dr. Paul I. Terasaki, the significance of humoral alloimmunity in liver transplantation has yet to be clearly defined. The liver allograft has an inherent tolerogenic capacity which confers its resistance to cell-mediated as well as antibody-mediated rejection. Nevertheless, the protection against alloimmunity is not complete, and antibody-mediated tissue injury can occur in the liver graft under specific circumstances. In this article the evidence on the clinicopathologic effects of donor-specific alloantibodies in liver transplantation will be examined and interpreted in parallel with lessons learned from renal transplantation. The unique anatomic and immunologic features of the liver will be reviewed to gain new insights into the complex interactions between humoral immune system and the liver allograft.

    Liver transplantation has become the treatment of choice for patients with end-stage liver disease. Most studies show a positive effect on quality of life after liver transplantation, but most studies are based on data from Western countries and little is known about quality of life in liver transplant recipients in Turkey or other developing countries. To investigate liver transplant recipients' quality of life and factors affecting it, before and 3 months after transplantation in western Turkey. Descriptive and comparative, with data collected prospectively. Two medical centers in Western Turkey. Sixty-five adult recipients of a liver transplant between May 15 and December 31,2007. Quality of life was measured by using the Nottingham Health Profile Turkish version, and sociodemographic and clinical data were collected from patients' records. Scores on all subscales of the Nottingham Health Profile differed significantly from before to after liver transplantation. The differences between the mean scores for quality of life before and after transplantation varied significantly with the patients' sex and disease severity.

    Achieving optimum outcomes after liver transplantation requires an understanding of the interaction between donor, graft and recipient factors. Within the cohort of patients waiting for a transplant, better matching of the donor organ to the recipient will improve transplant outcomes and benefit the overall waiting list by minimizing graft failure and need for re-transplantation. A PubMed search was conducted to identify published literature investigating the effects of donor factors such as ...

    Liver transplant is the criterion standard for patients with end-stage liver disease. Yet there is no liver transplant in Syria. Traveling abroad for a liver transplant is a luxury few Syrians can afford. There is currently an on-going debate whether to start a liver transplant program using living or deceased donors. In 2003, a new law was enacted, authorizing the use of organs from volunteer strangers and deceased donors. Despite the positive aspects of this law (allowing unrelated donors to increase the number of transplants in the country); the negative aspects also were obvious. The poor used the law to sell their organs to the rich, and this model is in violation of the Istanbul Declaration. To better document transplant communities' perceptions on organ donation, an e-mail survey was sent to a nationally representative sample of physicians (n = 115) that showed that 58% of respondents did not support the start of liver transplant from live donors, as they fear a considerable risk for the donor and the recipient. Seventy-one percent of respondents believe that unrelated kidney donation has contributed to tarnishing the reputation of transplant, and 56% believe that a deceased-donor program can run in parallel with unrelated organ donations. The interest in deceased-donor program has been affected negatively by the systematic approach of using poor persons as the source of the organ. This lack of interest has affected starting a liver program that relies on deceased donors; especially the need for kidneys is more than livers. Health authorities in Syria were inclined to initiate a liver transplant program from live donors, despite the risks of serious morbidities and mortality. In conclusion then, paid kidney donation in actual effect is actually a hindrance to establishing a deceased-donor liver program.

    Beginning to do liver transplants in a developing country is challenging. We report on the first few liver transplants performed in Qatar and discuss future exceptions and challenges facing our program. The first liver transplant was performed in Qatar on December 6, 2011. Since starting the program, 4 deceased-donor liver transplants have been performed in Qatar. All recipients underwent a standard deceased-donor liver transplant procedure, which included a duct-to-duct biliary anastomosis without a veno-venous bypass. All liver transplants were performed at the Hamad Medical Corporation by a local team of surgeons without external assistance. The 4 patients were all men, with a median age of 56 years (age range, 46-63 y). Indications for liver transplant included hepatitis C cirrhosis in 2 patients, and 1 patient with hepatitis B cirrhosis with hepatocellular carcinoma, and the other patient with cryptogenic liver cirrhosis. Median amount of blood transfused was 6 units (range, 0-10 U); median time spent in the intensive care unit was 2 days (range, 2-5 d); median amount of time spent in the hospital was 10 days (range, 9-16 d). All 4 recipients have survived after a median follow-up of 438 days (range, 33-602 d) and are enjoying a healthy life, with no significant posttransplant complications. A deceased-donor liver transplant can be performed in Qatar with no external assistance. However, a severe organ shortage remains the biggest obstacle facing us. Efforts should be directed toward improving the number and quality of available deceased donors in Qatar. Meanwhile, live-donor liver transplant may be the only way for us, going forward, to prevent deaths on the waiting list.

    The inflammatory milieu in the liver as determined by histopathology is different in individual patients undergoing autologous islet cell transplantation. We hypothesized that inflammation related to fatty-liver adversely impacts islet survival. To test this hypothesis, we used a mouse model of fatty-liver to determine the outcome of syngeneic islet transplantation after chemical pancreatectomy. Mice (C57BL/6) were fed a high-fat-diet from 6 weeks of age until attaining a weight of ≥28 grams (6-8 weeks) to produce a fatty liver (histologically > 30% fat);steatosis was confirmed with lipidomic profile of liver tissue. Islets were infused via the intra-portal route in fatty-liver and control mice after streptozotocin induction of diabetes. Outcomes were assessed by the rate of euglycemia, liver histopathology, evaluation of liver inflammation by measuring tissue cytokines IL-1β and TNF-α by RT-PCR and CD31 expression by immunohistochemistry. The difference in the euglycemic fraction between the normal liver group (90%, 9/10) and the fatty-liver group (37.5%, 3/8) was statistically significant at the 18 th day post- transplant and was maintained to the end of the study (day 28) (p = 0.019, X 2 = 5.51). Levels of TNF-α and IL-1β were elevated in fatty-liver mice (p = 0.042, p = 0.037). Compared to controls cytokine levels were elevated after islet cell transplantation and in transplanted fatty-liver mice as compared to either fatty- or islet transplant group alone (p = NS). A difference in the histochemical pattern of CD31 could not be determined. Fatty-liver creates an inflammatory state which adversely affects the outcome of autologous islet cell transplantation.

    Liver transplantation treats the hepatic affectation of UCDs; however, irreversible neurologic damage pretransplant is difficult to assess providing transplant teams with ethical dilemmas for liver transplantation. The purpose of our study was to determine whether pretransplant neuroimaging can predict developmental outcomes post-liver-transplant in children with UCDs. Patients undergoing liver transplantation for UCDs at Cincinnati Children's Hospital Medical Center between 2002 and 2012 were identified. Neurologic assessments prior to and after transplantation were categorized into mild, moderate, or severe disability. Neuroimaging data were categorized into mild, moderate, or severe by a single pediatric neuroradiologist. Fifteen patients were identified of whom eight had neuroimaging prior to transplantation. Of the eight patients that had neuroimaging, four were categorized as severe, one moderate, and three no-to-mild delay. All four patients whose imaging was severe were found to have moderate-to-severe neurologic delay. Of the three patients with no-to-mild changes on neuroimaging two of three were found to have no-to-mild delay on developmental assessments after transplantation. Neuroimaging may be a helpful tool in determining developmental prognosis and outcomes post-liver-transplantation for UCDs. Further studies maybe needed to validate our preliminary findings. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    In the first posttransplant month, the most frequent complications are due to technical problems related to complex vascular and bile duct reconstructions during the operation. Moreover, despite great improvements in suturing technique and materials, severe organ ischemia-reperfusion caused by time-consuming hand suturing is still an important factor in graft survival. During the operation, severe hypotension, hypoxic acidosis, hyperkalemia, and renal dysfunction may occur during the anhepatic phase due to the prolonged venous clamping time required for hand suturing. Therefore, hand suturing is a handicap in the development of further advancements in liver transplantation. In this study, we aimed to test a new "mechanical installation method" for rapid vascular reconstruction. The magnetic pinning-ring device was developed consisting of paired magnetic rings coated with titanium oxide and embedded in a polypropylene shell. The rings were equipped with alternately spaced holes and titanium pins. Forty adult mongrel dogs were randomly divided into groups: A (n = 16), all vascular and bile duct reconstruction by magnetic ring without venous bypass; B (n = 16), all vascular and bile duct reconstruction by hand suturing with venous bypass; C (n = 8), sham transplantation group, transection of all vessels and common bile duct followed by anastomosis with the magnetic rings without liver transplantation. From groups A and B, dogs were randomly selected as donors (n = 8) or recipients (n = 8) of liver transplantations. We recorded operation time, vascular and bile duct anastomosis time, anhepatic time, administration of supplemental fluids during operation, and survival; blood samples were collected for the detection of liver damage (alanine aminotransferase [ALT] and aspartate aminotransferase [AST]) and tumor necrosis factor α level. Patency was confirmed using ultrasound scans at various time points as late as 24 wk after surgery. Angiography was used to evaluate the

    To analyze clinical efficacy and prognosis of liver transplantation in children with hyperammonemia caused by urea cycle disorders. A retrospective analysis was performed on the occurrence of disease, operation and the follow-up post liver transplantation in 4 patients with urea cycle disorders who underwent liver transplantation during June 2001 to May 2014. Four girls were diagnosed with ornithine carbamoyl transferase deficiency by genetic test. They had the clinical onset at the age of 1.5 to 3.0 years. Liver transplantation had been performed at their age of 53.9 months, 40.6 months, 40.3 months and 22.8 months, respectively. The grafts of case 1 and case 2 were from left lateral lobe of liver of cadaveric donor, the graft of case 3 was from left lateral lobe of liver of a living donor, the graft of case 4 was a whole liver of a dead child. The liver function of 4 patients gradually returned to normal, blood ammonia levels were normal and restored the normal diet, 4 children were discharged on postoperative 25-30 days. Regular follow-up was done, the liver function, biochemical features and growth status have been followed up for 162.2 months, 124.2 months, 12.0 months and 4.8 months after liver transplantation, respectively. Now, all the four cases are healthy and growth is normal. Liver transplantation is an important way to the patients with severe hyperammonemia caused by urea cycle disorders. In this study, the patients with ornithine carbamoyl transferase defect got satisfactory long-term outcome after liver transplantation.

    Ethylmalonic encephalopathy is a fatal, rapidly progressive mitochondrial disorder caused by ETHE1 mutations, whose peculiar clinical and biochemical features are due to the toxic accumulation of hydrogen sulphide and of its metabolites, including thiosulphate. In mice with ethylmalonic encephalopathy, liver-targeted adeno-associated virus-mediated ETHE1 gene transfer dramatically improved both clinical course and metabolic abnormalities. Reasoning that the same achievement could be accomplished by liver transplantation, we performed living donor-liver transplantation in an infant with ethylmalonic encephalopathy. Unlike the invariably progressive deterioration of the disease, 8 months after liver transplantation, we observed striking neurological improvement with remarkable achievements in psychomotor development, along with dramatic reversion of biochemical abnormalities. These results clearly indicate that liver transplantation is a viable therapeutic option for ETHE1 disease. © The Author (2016).

    2015-01-01

    Full Text Available Living donor liver transplantation is a highly effective method to help children with end stage liver diseases. Projected success of operation is largely determined at the stage of selection of potential donor. In our review of the literature is presented historical information, are considered «eastern» and «western» way of development of pediatric living donor liver transplantation, are analyzed the ethical and psychosocial aspects of living donor liver transplantation, and also are set out principles and protocols for evaluation potential donors. In addition, the modern views on volumetry of the potential donor liver and on choice of graft type for transplantation, including for children with low weight are presented. 

  12. Concurrent Hepatic Artery and Portal Vein Thrombosis after Orthotopic Liver Transplantation with Preserved Allografts

    Full Text Available In contrast to early HAT, late HAT has an insidious clinical presentation. Nevertheless, biliary and vascular reconstructions in this late setting are unlikely to improve outcome. Patent portal flow makes an important contribution to the viability of liver in case of late HAT while the allograft reconstitutes intrahepatic arterial flow through neovascularization. Concurrent HAT with PVT without immediate graft necrosis is extremely rare, and allograft and patient survival are seemingly impossible without retransplantation. In fact, hepatopetal arterial and portal venous neovascularization are known albeit obscure phenomena that can preserve posttransplant hepatic function under the extenuating circumstances of complete interruption of blood flow to the graft. We describe two such cases that developed combined HAT and PVT more than six months after OLT with perfect preservation of graft function. The survival of allografts in our cases was due to extensive hepatopetal arterial and portal venous collateralization. Simultaneous HAT and PVT after OLT are rare events and almost uniformly fatal, if they occur early. Due to paucity of such cases, however, underlying mechanisms and etiology remain elusive, and despite radiological diagnosis of these complications, there is no way to predict these events in the wake of stable graft function.

    The epidemiological trend in liver diseases becomes more serious worldwide. Several recent articles published by International Journal of Surgery in 2018 particularly emphasized the encouraging clinical benefits of hepatectomy, liver regeneration and liver transplantation, however, there are still many technical bottlenecks underlying these therapeutic approaches. Remarkably, a few preliminary studies have shown some clues to the role of three-dimensional (3D) printing in improving traditional therapy for liver diseases. Here, we concisely elucidated the curative applications of 3D-printing (no cells) and 3D Bio-printing (with hepatic cells), such as 3D-printed patient-specific liver models and devices for medical education, surgical simulation, hepatectomy and liver transplantation, 3D Bio-printed hepatic constructs for liver regeneration and artificial liver, 3D-printed liver tissues for evaluating drug's hepatotoxicity, and so on. Briefly, 3D-printed liver models and bioactive tissues may facilitate a lot of key steps to cure liver disorders, predictably bringing promising clinical benefits. This work further provides novel insights into facilitating treatment of hepatic carcinoma, promoting liver regeneration both in vivo and in vitro, expanding transplantable liver resources, maximizing therapeutic efficacy as well as minimizing surgical complications, medical hepatotoxicity, operational time, economic costs, etc. Copyright © 2018.

    The purpose of this study was to identify significant, independent factors that predicted 6 month patient and graft survival after pediatric liver transplantation. The Studies of Pediatric Liver Transplantation (SPLIT) is a multicenter database established in 1995, of currently more than 4000 US and Canadian children undergoing liver transplantation. Previous published analyses from this data have examined specific factors influencing outcome. This study analyzes a comprehensive range of factors that may influence outcome from the time of listing through the peri- and postoperative period. A total of 42 pre-, peri- and posttransplant variables evaluated in 2982 pediatric recipients of a first liver transplant registered in SPLIT significant at the univariate level were included in multivariate models. In the final model combining all baseline and posttransplant events, posttransplant complications had the highest relative risk of death or graft loss. Reoperation for any cause increased the risk for both patient and graft loss by 11 fold and reoperation exclusive of specific complications by 4 fold. Vascular thromboses, bowel perforation, septicemia, and retransplantation, each independently increased the risk of patient and graft loss by 3 to 4 fold. The only baseline factor with a similarly high relative risk for patient and graft loss was recipient in the intensive care unit (ICU) intubated at transplant. A significant center effect was also found but did not change the impact of the highly significant factors already identified. We conclude that the most significant factors predicting patient and graft loss at 6 months in children listed for transplant are posttransplant surgical complications.

    There is currently no unified view regarding whether liver transplantation or splenectomy should be performed for hypersplenism before liver transplantation in biliary atresia (BA) patients. We herein describe the efficacy of splenectomy before liver transplantation. Splenectomy was performed in ten patients with hypersplenism associated with BA. We retrospectively reviewed their perioperative and postoperative courses, the number of leukocytes and thrombocytes, and the MELD score. The mean age was 17.5±7.0years (range 11-31years), and the male-to-female ratio was 1:1. The platelet and leukocyte levels increased after splenectomy and returned to normal levels one month postoperatively. The mean MELD score after splenectomy was significantly decreased after splenectomy: 10±2.1 vs 7.6±1.8. In particular, PT-INR improved. Five patients underwent liver transplantation because of hepatopulmonary syndrome and repeated bouts of cholangitis, whereas the remaining five patients did not undergo liver transplantation because of improvements in the liver function (the mean follow-up period was 56months). The postoperative complications included portal vein thrombosis and intestinal perforation, but the patient survival rates remained at 100%. After splenectomy, both pancytopenia and the liver function clearly improved. Splenectomy should therefore be a treatment option for patients with hypersplenism before liver transplantation.

    Objective: To study the accuracy of liver volume measurement using MSCT and its application in liver transplantation. Methods: (1) Experimental study. Ten pig livers were scanned using MSCT with two collimations (3.2 mm and 6.5 mm) and pitch 1.25. Semi-automatic method was used to reconstruct 3D liver models to measure the liver volume. (2) Clinical study. Twenty-three patients received MSCT scan with collimation of 6.5 mm before liver transplantation. Same method was used to calculate the liver volume and the measurement was repeated by the same observer after 1 month. Results: (1) Experimental study. Actual liver volumes were (1134.1 ± 288.0) ml. Liver volumes by MSCT with two collimations were (1125.0 ± 282.5) ml (3.2 mm) and (1101.6 ± 277.6) ml (6.5 mm). The accuracy was (99.5 ± 0.8)% and (97.4 ± 0.8)%, respectively. Both showed same good agreement with actual liver volume: r=0.999, P<0.01 (2) Clinical study. Actual liver volumes were (1455.7±730.0) ml. Liver volume by MSCT was (1462.7 ± 774.1) ml. The accuracy was (99.5±9.6)%, r=0.986, P<0.01. Liver volume measured again was (1449.4 ± 768.9) ml, r=0.991 (P<0.01). Conclusion: MSCT can assess the liver volume correctly, and could be used as a routine step for evaluations before liver transplantation

  18. Fixed Pupillary Light Reflex due to Peripheral Neuropathy after Liver Transplantation

    2015-08-01

    Full Text Available A 46-year-old female patient was admitted to the intensive care unit (ICU after liver transplantation. About an hour later after the ICU admission, she had no pupillary light reflex. Both pupils were also fixed at 5 mm. Patients who undergo liver transplantation are susceptible to neurologic disorders including hepatic encephalopathy, thromboembolism and intracranial hemorrhage. Abnormal pupillary light reflex usually indicates a serious neurologic emergency in these patients; however, benign neurologic disorders such as peripheral autonomic neuropathy or Holmes-Adie syndrome should also be considered. We experienced a case of fixed pupillary light reflex after liver transplantation diagnosed as peripheral autonomic neuropathy.

    Cadaver sources are insufficient for the increasing demand for liver transplantation. Right-lobe liver transplantation from living donors is fully developed in Japan and has been rapidly increasing in the United States during the past 2 years, although donor risk is greater than in other types of solid organ transplantation. The authors examine the psychiatric and ethical aspects of right-lobe liver transplantation in light of cultural differences between the United States and Japan.

    Objective: To affirm the application value of 99 Tc m -phytate scintigraphy in pig auxiliary liver transplantation. Methods: The graft was transplanted in the right subhepatic space of recipient to establish pig auxiliary liver transplantation model. The artery blood supplies were the very same in all grafts and the portal vein (PV) blood flows were differently controlled by trussing the host PV at the site neared host liver. According to the constriction degree, PV blood supplies were divided into three groups including A (constricted by 1/3), B (constricted by 1/2) and C(not constricted). The blood flows of the graft liver and the host liver were measured by 99 Tc m -phytate scintigraphy and livers functions were estimated after auxiliary liver transplantation. Contrasted with its histological findings the reflection of graft survival with 99 Tc m -phytate scintigraphy was investigated. Results: It was detected by 99 Tc m -phytate scintigraphy that the blood flows were almost equilibrated and abundant in grafts and host liver' in group A, and were abundant in grafts of group B and host livers of group C and were significantly decreased in host livers of group B and grafts of group C. Histological work-up demonstrated that the liver was not atrophic while the blood flow was abundant and the liver was atrophic while the blood flow was decreased. Conclusion: 99 Tc m -phytate scintigraphy could accurately reflect the survival and function of grafts and host livers after auxiliary liver transplantation and it is a reliable technique which can be used to estimate the survival and function of the grafts and host livers

    To evaluate the value of CT in clarifying the nature of complications after orthopedic liver transplantation, we restrospectively evaluated the files of 88 patients in light of the clinical course and all available diagnostic data. The liver tranplantations were performed in the years 1986 and 1987. As a rule, the examinations comprised of continuous 8 mm-thick CT sections of the abdomen. In the majority of the cases, contrast medium was administered for opacification of the bowel loops, either orally or through a tube. Bowel movement was reduced by intravenous (i.v.) Buscopan. In our series an increase in the periportal hypodensities was found to be an unfavourable prognostic sign. A high percentage of patients with this CT finding subsequently progressed to graft failure due to reasons other than graft rejection. Hence in the final analysis, the CT sign is non-specific and does not permit the definitive diagnosis of graft rejection. Nevertheless, CT is important for excluding conditions that demand surgical intervention, in particular abscess formation. (orig./MG)

    Urea cycle disorders (UCD) are caused by rare inherited defects in the urea cycle enzymes leading to diminished ability to convert ammonia to urea in the liver. The resulting excess of circulating ammonia can lead to central nervous system toxicity and irreversible neurologic damage. Most cases are identified in children. However, UCDs can also be diagnosed in adulthood, and liver transplant is occasionally required. We examined the UNOS database to evaluate outcomes in adult and pediatric patients who underwent liver transplant as treatment for a UCD. We identified 265 pediatric and 13 adult patients who underwent liver transplant for a UCD between 1987 and 2010. The majority (68%) of these patients were transplanted before age 5 years. Ornithine transcarbamylase (OTC) deficiency was the most common UCD in both adults and children who underwent transplant. UCD patients who underwent liver transplant were younger, more likely to be male (67%), had lower pediatric end-stage liver disease/model for end-stage liver disease scores, and were more likely to be Caucasian or Asian compared with all other patients transplanted during the same time period. UCD patients did not have an increased utilization of living donor transplantation in this US cohort. Univariate and multivariate risk factor analyses were performed and did not reveal any significant factors that were predictive of post-transplant death or graft loss. Excellent outcomes were seen in both children and adults with UCDs who underwent transplant with overall 1-, 5-, and 10-year survivals of 93%, 89%, and 87%, respectively.

  3. Aspergillus Tracheobronchitis Causing Subtotal Tracheal Stenosis in a Liver Transplant Recipient

    Directory of Open Access Journals (Sweden)

    2013-01-01

    Full Text Available Invasive aspergillosis is recognized as one of the most significant opportunistic infections after liver transplantation. Diagnosis of invasive aspergillosis in transplant recipients has been proven to be challenging, and optimal approach to the treatment of invasive aspergillosis is still controversial. We here present an unusual case of Aspergillus tracheobronchitis in the setting of liver transplantation. A 47-year-old female patient with persistent dry cough after liver transplantation developed respiratory insufficiency and was readmitted to the intensive care unit 55 days after liver transplantation. A CT scan revealed subtotal tracheal stenosis; bronchoscopy was performed, and extended white mucus coverings causative of the tracheal stenosis were removed. Microbiological assessment isolated Aspergillus fumigatus. The diagnosis was obstructive Aspergillus tracheobronchitis. The patient was started on a treatment of voriconazole 200 mg orally twice daily, adjusted to a trough level of 1–4 mg/L. For further airway management, a tracheal stent had to be implanted. The patient is alive and well 28 months after liver transplantation. Invasive aspergillosis should be considered a possible etiology in liver transplant patients presenting with unspecific symptoms such as persistent dry cough. Optimal strategies for improved and early diagnosis as well as prophylaxis need to be defined.

    Patients infected with the human immunodeficiency virus (HIV) have generally been excluded from consideration for liver transplantation. Recent advances in the management and prognosis of these patients suggest that this policy must be reevaluated. To identify the current position of Brazilian transplant centers concerning liver transplantation in asymptomatic HIV-infected patients with end-stage liver disease. A structured questionnaire was submitted by e-mail to Brazilian groups who perform liver transplantation and were active in late 2003, according to the Brazilian Association of Organ Transplantation. Of the 53 active groups, 30 e-mail addresses have been found of professionals working in 41 of these groups. Twenty-one responses (70%) were obtained. Most of the professionals (62%) reported that they do not include HIV-infected patients in waiting lists for transplants, primarily on account of the limited world experience. They also reported, however, that this issue will soon be discussed by the group. Those who accept these patients usually follow the guidelines provided by the literature: patients must fulfill the same inclusion criteria as the other patients with end-stage liver diseases, present low or undetectable HIV viral load, and a CD4 count above 250/mm3. They reported that there are 10 HIV-infected patients in waiting list and that only one patient has received a liver transplant in the country. Most centers do not accept in waiting lists for liver transplantation patients with HIV infection, even asymptomatic ones. However, advances in the management of HIV-infected patients suggest that this policy must be reevaluated. In Brazil, there is practically no experience in liver transplantation in HIV-positive patients.

    Surgical site infection is more frequent in liver transplantation than in other types of solid organ transplantation with different antibiotics. Studies have shown that the rate of surgical site infection varies from 8.8% to 37.5% after liver transplantation. Therefore, antimicrobial prophylaxis is likely an essential tool for reducing these infections. However, the literature lacks evidence indicating the best prophylactic antibiotic regimen that can be used for liver transplantation. To assess the benefits and harms of antibiotic prophylactic regimens for surgical site infection in people undergoing liver transplantation. We searched the Cochrane Hepato-Biliary Group Controlled Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, Science Citation Index Expanded and Latin American Caribbean Health Sciences Literature (LILACS). The most recent search was performed on 11 September 2015. All eligible randomised clinical trials comparing any antibiotic regimen versus placebo, versus no intervention or versus another antibiotic regimen for surgical site infection in liver transplant recipients, regardless of age, sex and reason for transplantation. Quasi-randomised studies and other observational studies were considered for data on harm if retrieved with search results for randomised clinical trials. Two review authors selected relevant trials, assessed risk of bias of studies and extracted data. The electronic search identified 786 publications after removal of duplicates. From this search, only one seemingly randomised clinical trial, published in abstract form, fulfilled the inclusion criteria of this review. This trial was conducted at Shiraz Transplant Centre, Shiraz, Iran, where investigators randomly assigned a total of 180 consecutive liver transplant recipients. We judged the overall risk of bias of the trial published in abstract form as high. Researchers reported no numerical data but mentioned that 163 participants

    2013-04-01

    Postshunt hepatic encephalopathy after liver transplantation (LT) is an infrequent condition and is commonly associated with portal occlusion or stenosis and the presence of a patent portosystemic shunt. Portal vein stenosis (PVS) or thrombosis (PVT) are uncommon complications after LT. The overall frequency of both complications is reported to be less than 3%. When PVS or PVT develop early after LT, the occlusion of the portal vein can have catastrophic consequences to the graft including acute liver failure and graft loss. Late PVT/PVS are asymptomatic in approximately 50% of the cases and mainly diagnosed by a routine ultrasound. Symptomatic postshunt hepatic encephalopathy (HE) is a very infrequent condition after LT that has been scarcely reported in the literature. We present here the case of a liver recipient with normal graft function who presented with hepatic encephalopathy 3 months after LT with stable liver function but a severe portal stenosis and the presence of a spontaneous portosystemic shunt whose successful endovascular treatment was followed by the complete resolution of the HE.

    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 α-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.

  8. A review of the imaging and intervention of liver transplant complications.

    2010-09-01

    Liver transplantation has become a successful surgical solution to a variety of medical and oncological parenchymal liver diseases. As a result, these patients are being encountered more frequently within diagnostic imaging departments which may be remote from the transplant centre. Radiologists must therefore be proficient in identifying normal post-transplant anatomy which involves the anastomosis of four structures between the donor and recipient, namely the hepatic artery, the main portal vein, the retro-hepatic inferior vena cava and the extra-hepatic bile ducts. A number of potential complications can arise involving any or all of these structures, which can be potentially devastating and lead to graft failure. Radiologists must familiarise themselves with the normal post-operative appearances of liver transplantation and become competent in diagnosing post-transplant complications. Where possible, complications should be treated using interventional radiological techniques, thus avoiding the need for repeat surgical intervention or retransplantation.

    Evaluating transplantation grafts at harvest is essential for its success. Laser-induced fluorescence spectroscopy (LIFS) can help monitoring changes in metabolic/structural conditions of tissue during transplantation. The aim of the present study is to correlate LIFSobtained spectra of human hepatic grafts during liver transplantation with post-operative patients' mortality rate and biochemical parameters, establishing a method to exclude nonviable grafts before implantation. Orthotopic liver transplantation, piggyback technique was performed in 15 patients. LIFS was performed under 408nm excitation. Collection was performed immediately after opening donor's abdominal cavity, after cold perfusion, end of back-table period, and 5 min and 1 h after warm perfusion at recipient. Fluorescence information was compared to lactate, creatinine, bilirubin and INR levels and to survival status. LIFS was sensitive to liver changes during transplantation stages. Study-in-progress; initial results indicate correlation between fluorescence and life/death status of patients.

    Multidetector row CT is a feasible diagnostic tool in pre- and postoperative liver partial transplantation. We can assess vascular anatomy and liver parenchyma as well as volumetry, which provide useful information for both donor selection and surgical planning. Disorders of the vascular and biliary systems are carefully observed in recipients. In addition, we evaluate liver regeneration of both the donor and the recipient by serial volumetry. We present how multidetector row CT with state-of-the-art three-dimensional volume renderings may be used in right lobe liver transplantation. (orig.)

    We aim to study the impact of the baby boomer (BB) generation, a birth-specific cohort (born 1945-1965) on hepatocellular carcinoma (HCC)-related liver transplantation (LT) in patients with chronic hepatitis C virus (HCV), alcoholic liver disease (ALD), and non-alcoholic steatohepatitis (NASH). We performed a retrospective analysis using the United Network for Organ Sharing (UNOS)/Organ Procurement Transplant Network (OPTN) database from 2003 to 2014 to compare HCC-related liver transplant surgery trends between two cohorts-the BB and non-BB-with a secondary diagnosis of HCV, ALD, or NASH. From 2003-2014, there were a total of 8313 liver transplant recipients for the indication of HCC secondary to HCV, ALD, or NASH. Of the total, 6658 (80.1%) HCC-related liver transplant recipients were BB. The number of liver transplant surgeries for the indication of HCC increased significantly in NASH (+1327%), HCV (+382%), and ALD (+286%) during the study period. The proportion of BB who underwent LT for HCC was the highest in HCV (84.7%), followed by NASH (70.3%) and ALD (64.7%). The recommendations for birth-cohort specific HCV screening stemmed from a greater understanding of the high prevalence of chronic HCV and HCV-related HCC within BB. The rising number of HCC-related LT among BB with ALD and NASH suggests the need for increased awareness and improved preventative screening/surveillance measures within NASH and ALD cohorts as well.

    Full Text Available End stage liver disease is often associated with growth retardation in children with congenital and hereditary diseases of hepatobiliary system. The aim was to investigate the serum growth hormone level before and after liver transplantation in 52 children with congenital and hereditary diseases of hepatobiliary system. Data of our research work revealed increased serum level of growth hormone in children with liver cirrhosis (3,32 ± 7,7 ng/ml vs. 1,16 ± 1,46 ng/ml in healthy children, p = 0,01, which correlates with PELD score (r = 0,62, p < 0,001. In a month after liver transplantation growth hormone concentration decreases (p < 0,001 and in a year after transplantation it doesn’t differ from healthy children. There wasn’t revealed any interaction between serum growth hormone level and anthropometric parameters before liver transplantation, but in a year after there was significant correlation between growth hormone concentration and height (r = 0,79, p = 0,01. Investigation of growth hormone level in children with liver cirrhosis and its evolution after liver transplantation is of interest as objective criterion of recovery of physical development regulation and as an additional parameter, which cor- relates with severity of end-stage liver disease.

    Liver failure is a life-threatening liver disease encompassing severe acute deterioration of liver function. Emergency liver transplantation is the only curative treatment for liver failure, but is restricted by the severe shortage of organ donors. Stem cell, including embroyonic stem cells, induced pluripotent stem cells, mesenchymal stem cells, hematopoietic stem cells and hepatic progenitor cells, have capacity to proliferate and differentiate and could be used in a variety of liver diseases including hereditary liver diseases, cirrhosis and liver failure. We summarized the basic experimental and clinical advances of stem cell transplantation in liver failure treatment, and also discussed the advantages and disadvantage of different stem cells subtype in this field, aiming to provide a perspective on the stem cell-based therapy for liver failure. Stem cells, especially mesenchymal stem cells (mainly low immunogenicity and paracrine characteristics) and induced pluripotent stem cells (generation of desired cell type from somatic cell), are feasible candidates for cell therapy in the treatment of liver failure, but there are some drawbacks remaining to be resolved, such as low engraftment, cryotpreservation methods and tumorigenesis. Stem cell transplantation is a promising but challenging strategy and paves a new way for curing liver failure. But more efforts need to be made to overcome problems before this new strategy could be safely and effectively applied to humans.

    There is a worldwide problem of acute liver failure and mortality associated with remaining on the waiting for a liver transplant. In this study, we highlight results published in recent years by leading transplant centers in evaluating imatinib-induced acute liver failure in chronic myeloid leukemia and follow-up in liver transplantation. A 36-year-old brown-skinned woman (mixed Brazilian race) diagnosed 1 year earlier with chronic myeloid leukemia was started after delivery of a baby and continued for 6 months with imatinib mesylate (selective inhibitor of Bcr-Abl tyrosine kinase), which induced liver failure. We conducted a literature review using the PubMed database for articles published through September 2017, and we demonstrate a role of liver transplant in this situation for imatinib-induced liver failure. We report previously published results and a successful liver transplant after acute liver failure due to imatinib-induced in chronic myeloid leukemia treatment. We report a case of a successful liver transplant after acute liver failure resulting from imatinib-induced chronic myeloid leukemia treatment. The literature reveals the importance of prompt acute liver failure diagnosis and treatment with liver transplant in selected cases.

    Living donor liver transplant has gained rapid popularity in India as a life saving procedure for end stage liver disease. The undoubted benefit for the recipient is clouded by a few unfavorable outcomes in donors which have led to allegations of lack of transparency. These factors are easily remediable with an attitude of self audit and self disclosure by transplant centers, enabling a truly informed consenting procedure.

    A high prevalence of posttraumatic stress disorder (PTSD) symptoms among transplant recipients has been associated with a low adherence to treatment and poor survival. It is crucial to detect and prevent the development of posttraumatic stress in transplant settings. We examined the prevalence of posttraumatic stress symptoms in 3 liver transplant recipients by means of the Essen Trauma Inventory (ETI), a self-report questionnaire. The Short Form-36 was used to assess the perceived health-related quality of life. Patients were asked to indicate the most traumatic events within the context of the liver transplantation procedure. Five patients (4.9%) fulfilled the criteria for PTSD related to liver disease or transplantation (ETI score greater than 27). In these patients, diagnosis was confirmed by a structured clinical interview. Fourteen (13.6%) patients had a partial PTSD with the ETI score less than 27 and greater than 16. Posttraumatic stress symptoms were significantly associated with perceived poor physical and mental health-related quality of life. Patients reported that the physicians' disclosure of diagnosis was experienced as traumatic, followed by treatment in an intensive care unit and the liver transplantation itself. The ETI resulted in prevalence rates for PTSD comparable to previous studies in liver transplantation settings. Medical professionals requested additional training in how to deliver severe diagnoses to patients.

  6. Graft-Versus-Host Disease after Liver Transplantation Complicated by Systemic Aspergillosis with Pancarditis

    2000-01-01

    Full Text Available Acute graft-versus-host disease (GVHD is a common complication after bone marrow transplantation, with characteristic rash and diarrhea being the most common features. After liver transplantation, however, this phenomenon is very rare. Most transplant patients are on a variety of medications, including immunosuppressants; therefore, the differential diagnosis of skin rash or diarrhea is broad. A 37-year-old man who underwent liver transplantation for primary biliary cirrhosis, and developed a rash and watery diarrhea, is presented. Skin and colonic biopsies confirmed acute GVHD. A pulse of intravenous steroids was given. The skin rash improved, but he developed pancytopenia. His course was complicated by central line infection, jugular and subclavian vein thrombosis, pseudomembranous colitis, recurrent bacteremia, cholestasis on total parenteral nutrition and cytomegalovirus infection. After the onset of pleuritic chest pain and clinical sepsis, spiral computed tomography scan of his chest and abdomen revealed septic infarcts in multiple organs. Despite empirical treatment with amphotericin B, he died of multiorgan dysfunction syndrome within 72 h. Autopsy revealed systemic aspergillosis with pancarditis, endocardial vegetations, and septic pulmonary, splenic, hepatic and renal infarcts. The pathogenesis and experience with this rare, but often fatal, complication of liver transplantation are reviewed. In contrast to GVHD after bone marrow transplantation, pancytopenia is common and liver dysfunction is rare. One should have a high level of suspicion in the liver transplant recipient presenting with rash and/or diarrhea.

    To describe how registered nurse work motivation, attitudes, subjective norm and perceived behavioural control influence intention to promote physical activity in hospitalised adult liver transplant recipients. Descriptive study of clinical registered nurses caring for recipients of liver transplant at a tertiary medical centre. Intent to Mobilise Liver Transplant Recipient Scale, Work Extrinsic and Intrinsic Motivation Scale, and demographics were used to explore registered nurses' work motivation, attitudes, subjective norms, perceived behavioural control and intention to promote physical activity of hospitalised adult liver transplant recipients during the acute postoperative phase. Data analysis included demographics, comparison between scale items and analysis of factors predicting intent to mobilise. Factors predictive of intention to promote physical activity after liver transplant included appropriate knowledge to mobilise patients (R 2  = .40) and identification of physical activity as nursing staff priority (R 2  = .15) and responsibility (R 2  = .03). When implementing an early mobilisation protocol after the liver transplant, education on effects of physical activity in the immediate postoperative period are essential to promote implementation in practice. Nursing care environment and leadership must be supportive to ensure mobility is a registered nurse priority and responsibility. Nursing managers can leverage results to implement a mobility protocol. © 2017 John Wiley & Sons Ltd.

    Liver transplantation is intended to increase the survival of patients with chronic liver disease in terminal phase, as well as improved quality of life. Since the first transplant until today many changes have occurred in the organ allocation system. To review the literature on the Model for End-stage Liver Disease (MELD) and analyze its correlation with survival after liver transplantation. An integrative literature review in Lilacs, SciELO, and Pubmed in October 2015, was realized. Were included eight studies related to the MELD score and its impact on liver transplant. There was predominance of transplants in male between 45-55 y. The main indications were hepatitis C, hepatocellular carcinoma and alcoholic cirrhosis. The most important factors post-surgery were related to the MELD score, the recipient age, expanded donor criteria and hemotransfusion. The MELD system reduced the death rate in patients waiting for a liver transplant. However, this score by itself is not a good predictor of survival after liver transplantation. O transplante de fígado tem como finalidade o aumento da sobrevida dos pacientes com doença hepática crônica em fase terminal, além de melhora na qualidade de vida.

    Full Text Available BACKGROUND: Fulminant hepatic failure carries a high morbidity and mortality. Liver transplantation has markedly improved the prognosis of patients with fulminant hepatic failure. AIM: To evaluate the outcome of 20 patients with acute liver failure and indication for liver transplantation. METHODS: A retrospective review of 20 patients with acute liver failure and indication for liver transplantation was performed. Patients were divided into two groups: group A with 12 patients who underwent liver transplantation and group B with 8 patients who did not receive liver transplantation. Both groups were analyzed according to age, sex, ABO blood type, etiology of acute liver failure, time on list until transplantation or death, and survival rates. Group A patients were additionally analyzed according to preoperative INR, AST, and ALT peak values and MELD (Model for End-stage Liver Disease scores; intraoperative red blood cells and plasma transfusion and cold ischemia time; postoperative lenght of intensive care unit and hospital stay, and needed for dialysis. RESULTS: Group A: there were four men and eight women with an average age of 24.6 years. The average liver waiting time period was 3.4 days and MELD score 36. Seven patients are alive with good hepatic function at a medium follow-up of 26.2 months. The actuarial survival rate was 65.2% at 1 year. Group B: There were two men and six women with an average age of 30.9 years. The mean waiting time on list until death was 7.4 days. All patients died while waiting for a liver donor. CONCLUSION: Despite the improvements in intensive care management, most patients with acute liver failure and indication for liver transplantation ca not survive long without transplant. Liver transplantation is potentially the only curative modality and has markedly improved the prognosis of those patients.RACIONAL: OBJETIVO: Avaliar a evolução de 20 pacientes com insuficiência hepática aguda e indicação de

    Full Text Available Background. In this brief note we present the preliminary findings of a study of 16 women who underwent liver transplants before becoming pregnant and giving birth. The aim of the study was to show the similarities and differences between ways women experience the transplanted organ (liver and the fetus. Methods. To explore bodily experiences, a semi-structured ad hoc interview was done on a sample of 16 transplanted women who had completed a pregnancy. The interview was designed to explore the possible similarities between their perception of the transplanted organ (liver and of the fetus. Results. The main findings that emerge from our study are the following: a in the post-transplant, pre-pregnancy phase, these women develop a polarized attention on the transplanted organ; b during pregnancy this attention shifts towards the fetus; c after childbirth the hyper-attention on the transplanted organ disappears and the subject resumes a normal relationship with her body. Conclusions. Therefore, pregnancy and childbirth are experiences that can normalize relations between a person who has undergone a transplant and their transplanted organ.

    Full Text Available O sucesso dos transplantes de fígado certamente seria comprometido se a avaliação pré-operatória dos pacientes não fosse realizada de forma adequada. Isto se justifica devido ao reconhecimento de que o sucesso da cirurgia depende, em princípio, do diagnóstico da doença de base, da determinação de sua extensão e do grau de repercussão sistêmica. No final das décadas de setenta a noventa os progressos da hepatologia na identificação das hepatites virais e no manejo da ascite e da síndrome hepatorrenal melhoraram sobremaneira a expectativa de vida do doente portador de doença hepática crônica. Mas, sem dúvida o transplante ortotópico do fígado (TOF foi o espetacular avanço da hepatologia moderna. Atualmente o transplante é um tratamento eficaz das hepatopatias crônicas, e o índice de sobrevivência global aos 3 anos é ao redor de 80%. É, portanto, uma alternativa de tratamento indicada nos casos terminais, onde a mortalidade com tratamentos conservadores pode atingir até 70% ao final de 12 meses. Neste artigo, os autores comentam aspectos do TOF, relacionados à indicação e a sobrevida.The success of liver transplantation would be certainly compromised if the pre-operative evaluation was not adequately performed. The success of the liver transplantation depends on the diagnosis of the underlying hepatic disease, the determination of its extension and the degree of systemic repercussion.

Undoubtedly, orthotopic liver transplantation represents a great advance in modern hepatology. Nowadays, liver transplantation represents a valid therapeutic option for chronic liver diseases with (and presents a mean survival rate of about 80% in 3 years.

    Purpose: Exact preoperative determination of the liver volume is of great importance prior to hepatobiliary surgery, especially in living donated liver transplantation (LDLT). In the current literature, a strong correlation between preoperatively calculated and intraoperatively measured liver volumes has been described. Such accuracy seems questionable, primarily due to a difference in the perfusion state of the liver in situ versus after explantation. Purpose of the study was to asses the influence of the perfusion state on liver volume and the validity of the preoperative liver volumetry prior to LDLT. Methods: In an experimental study, 20 porcine livers were examined. The livers were weighted and their volumes were determined by water displacement prior and after fluid infusion to achieve a pressure physiologically found in the liver veins. The liver volumes in the different perfusion states were calculated based on CT-data. The calculated values were compared with the volume measured by water displacement and the weight of the livers. Results: Assessment of calculated CT volumes and water displacements at identical perfusion states showed a tight correlation and differed on average by 4 ± 5%. However, livers before and after fluid infusion showed a 33 ± 8% (350 ± 150 ml) difference in volume. Conclusion: CT-volumetry acquires highly accurate data as confirmed by water displacement studies. However, the perfusion state has major impact on liver volume, which has to be accounted for in clinical use. (orig.) [de

    2006-12-01

    Increased pre- and posttransplantation values of soluble CD30 (sCD30) have been shown to be associated with acute kidney transplant rejection. We sought to study whether high sCD30 could predict rejection early after liver transplantation. The study population included 54 consecutive liver transplant patients, whose samples were collected before liver transplantation and at discharge, which was at a mean time of 3 weeks after transplantation. During the first 6 months posttransplantation, 22 patients experienced an acute rejection episode. Serum sCD30 concentrations were measured by an enzyme-linked immunoassay; changes in serum sCD30 levels posttransplantation were also expressed as relative values compared with pretransplantation results. Liver patients before transplantation displayed higher serum sCD30 values compared with healthy controls: mean values +/- SD were 93 +/- 58 IU/mL vs 17 +/- 8 IU/mL, respectively. At 3 weeks after transplantation the mean sCD30 concentration in liver transplant patients decreased to 59 +/- 42 IU/mL (P = .005). The mean pretransplantation serum sCD30 value was slightly lower among rejecting vs nonrejecting patients: 78 +/- 43 IU/mL vs 104 +/- 65 IU/mL (P = NS). Posttransplantation values in both groups decreased significantly: 47 +/- 34 IU/mL in patients with rejection (P = .014) vs 69 +/- 45 IU/mL in patients without rejection (P = .012). The relative value at 3 weeks posttransplantation decreased slightly more among patients with vs without rejection (70% vs 88%; NS). No correlation was found between serum sCD30 and anti-HLA class I antibodies or crossmatch positivity. In conclusion, neither pre- nor posttransplantation sCD30 levels were associated with acute rejection in liver transplant patients.

     Background and rationale. Acoustic radiation force impulse (ARFI) is a non-invasive tool used in the evaluation of liver fibrosis in HCV positive immune-competent patients. This study aimed to assess the accuracy of ARFI in discriminating liver transplanted patients with different graft fibrosis severity and to verify whether ARFI, eventually combined with non-invasive biochemical tests, could spare liver biopsies. This prospective study included 51 HCV positive liver transplanted patients who consecutively underwent to annual liver biopsy concomitantly with ARFI and blood chemistry tests measurements needed to calculate several non-invasive liver fibrosis tests. Overall ARFI showed an AUC of 0.885 in discriminating between patients without or with significant fibrosis (Ishak score 0-2vs. 3-6). Using a cut-off of 1.365 m/s, ARFI possesses a negative predictive value of 100% in identifying patients without significant fibrosis. AUC for Fibrotest was 0.848 in discriminating patients with Ishak fibrosis score 0-2 vs. 3-6. The combined assessment of ARFI and Fibro-test did not improve the results obtained by ARFI alone. ARFI measurement in HCV positive liver transplanted patients can be considered an easy and accurate non-invasive tool in identify patients with a benign course of HCV recurrence.

    Pituitary apoplexy occurring after surgery is a rare but life-threatening acute clinical condition that follows extensive hemorrhagenous necrosis within a pituitary adenoma. Pituitary apoplexy has been reported to occur spontaneously in the majority of cases or in association with various inducing factors. Reported is a case of pituitary apoplexy complicated by diabetes insipidus following living donor liver transplantation (LDLT). To the best of our knowledge, this has not been previously reported. A 56-year-old woman with nonalcoholic steatohepatitis underwent LDLT from her daughter. The patient also required dopamine support and transfusions because of massive intraoperative bleeding. Postoperatively, her coagulopathy continued, and she underwent a second laparotomy because of unknown bleeding on postoperative day 7, when she needed transfusions and dopamine support to maintain her vital signs. She complained of severe headache, excessive thirst, frequent urination, and diplopia from postoperative day 10. She also had polyuria greater than 300 ml/h and was diagnosed with pituitary apoplexy precipitating diabetes insipidus on postoperative day 13. She was treated conservatively without surgery because of the hormonally inactive status and slight mass effect of her tumor. It is important for anesthesiologists and critical care personnel in LDLT settings to take into consideration this complication as a differential diagnosis.

    With an increasing number of liver transplantation (LT) and an enhanced overall survival, LT recipients are more likely to be admitted in emergency departments of general hospitals. Yet, in LT recipients, common but also benign symptoms may reveal a LT-related (or not) severe condition. To improve management of LT recipients by emergency physicians and general surgeons and potentially improve long-term outcomes, a clinical review was performed. Overall, CT scan and blood tests should be systematically performed. Immunosuppressive side effects should be excluded using blood tests. LT-related complications are more likely to occur during the first three months after LT, including mainly bile leak, arterial aneurysm, and pseudoaneurysm. Patients should be referred in emergency to tertiary centers. Non-LT-related complications and common abdominal conditions may also be diagnosed in LT recipients. Except in case of diffuse peritonitis or in hemodynamically unstable patients when surgical procedure should be performed, most conditions should be reassessed regarding the immunosuppressive treatment and the adhesive abdominal cavity. © 2017 John Wiley & Sons A/S.

    Hepaticojejunostomy is a well-accepted method, whereas duct-to-duct anastomosis is gaining popularity for bile duct reconstruction in pediatric living donor liver transplantation (LDLT). Biliary complications, especially biliary anastomotic stricture (BAS), are not clearly defined. The aim of the present study is to determine the rate of BAS and its associated risk factors. The study included 78 pediatric patients (duct-to-duct anastomosis during LDLT. The median follow-up period for the BAS group and the non-BAS group was 57.8 and 79.5 months, respectively (P = .683). Ten of the patients with BAS required percutaneous transhepatic biliary drainage with or without dilatation for treating the stricture. Multivariable analysis showed that hepatic artery thrombosis and duct-to-duct anastomosis were 2 risk factors associated with BAS. In pediatric LDLT, hepaticojejunostomy is the preferred method for bile duct reconstruction, but more large-scale research needs to be done to reconfirm this result. Copyright © 2012 Elsevier Inc.

    Pediatric obesity has become a significant public health concern. The historical focus in pediatric liver transplant (LT) has been undernutrition, with limited knowledge regarding obesity. Therefore, we sought to determine the prevalence of obesity in pediatric LT, compare it to National Health and Nutrition Examination Surveys (NHANES) data, and identify risk factors for obesity in pediatric LT. SPLIT, which collects pediatric LT data at 39 centers, was queried for subjects ages 2 to 18 years at follow-up, LT between 1995 and 2007, and with at least 1 body mass index measured 1 to 5 years after LT. Of 1706 individuals included, 44% had biliary atresia (47% boys, 58% white, mean age at LT 4.6 years). Of these individuals, 19% were obese at 1 year and 18% at 3 years, higher than in the general pediatric population reported by 2003-2004 NHANES, whereas 11% obesity at 5 years after LT was similar to NHANES data. Using logistic regression, Hispanic ethnicity (odds ratio [OR] 1.8, 95% confidence interval [CI] 1.19-2.23), steroid use at follow-up (OR 1.48, 95% CI 1.23-1.77), overweight (OR 4.34, 95% CI 2.91-6.68), and obesity (OR 10.62, 95% CI 5.9-19.65) at LT independently predicted post-LT obesity. These findings suggest a need to broaden standard care to include obesity assessment and intervention in routine pre- and posttransplant care.

    Previously described neurologic damage induced by immunosuppressive treatments includes transient or reversible central nervous system involvement. We describe a 57-year-old man who underwent liver transplantation and was started on immunosuppressive therapy with tacrolimus (FK506). Six months later, he started complaining of a progressive motor and sensory impairment of the left side, together with cognitive impairment. Brain MRI showed an enlarging lesion of the white matter with peripheral contrast enhancement. PET study indicated severe hypometabolism in the right hemisphere and spectroscopic MRI showed a peak of choline and relative reduction of other metabolites. Findings of CSF examinations and cultures, serology, and molecular techniques were normal. Tacrolimus treatment was stopped. A cerebral biopsy of the lesion showed a sub acute necrotizing process. In the following months, cognitive status of the patient tended to improve although he remained hemiplegic, while serial MRI confirmed the tendency to the recovery of the lesion that was still present 1 year after. The present observation describes a progressive encephalopathy associated with immune suppression with an unusual feature and permanent brain damage.

    Full Text Available Endoscopic treatment of biliary strictures involving plastic stent placement has been used widely. The use of self-expandable metal stents (SEMSs has been described for anastomotic strictures following liver transplantation (LT. This review aimed to assess and compare the efficacy of plastic stents with SEMS in LT patients. Information was retrieved regarding technical success, stricture resolution, the number of endoscopic retrograde cholangiography procedures, follow-up, immediate, and late complications. Eight studies involving plastic stents had a stricture resolution rate of 84.5%, with the rates ranging from 63% to 100%. These rates are comparable with the stricture resolution rate of 75% determined from six studies that involved 236 patients who received metal stents and the rates ranged from 53% to 81%. The observed success rate for metal stents used to manage post-LT anastomotic biliary strictures was below the reported rate for multiple plastic stents. Hence, the currently available metal stents should not be offered for the management of post-LT anastomotic biliary strictures.

    Conclusion: Although the number of cases of tuberculosis is low, its post-transplant frequency is significant and the observed mortality rate is not to be neglected. The cases of hepatotoxicity and graft rejection seen in this case series demonstrate the challenges associated with tuberculosis diagnosis in liver transplant recipients and management of the interactions between immunosuppressors and rifampin. This study strengthens the recommendation of latent tuberculosis infection screening and treatment in liver transplant candidates or recipients.

    Engraftment of transplanted cells is critical for liver-directed cell therapy but most transplanted cells are rapidly cleared from liver sinusoids by proinflammatory cytokines/chemokines/receptors after activation of neutrophils or Kupffer cells. To define whether TNF-α served roles in cell-transplantation-induced hepatic inflammation, we used TNF-α antagonist, etanercept, for studies in syngeneic rat hepatocyte transplantation systems. After cell transplantation, multiple cytokines/chemokines/receptors were overexpressed, whereas etanercept prior to cell transplantation essentially normalized these responses. Moreover, ETN downregulated cell transplantation-induced intrahepatic release of secretory cytokines, such as high mobility group box 1. These effects of etanercept decreased cell transplantation-induced activation of neutrophils but not of Kupffer cells. Transplanted cell engraftment improved by several-fold in etanercept-treated animals. These gains in cell engraftment were repeatedly realized after pretreatment of animals with etanercept before multiple cell transplantation sessions. Transplanted cell numbers did not change over time indicating absence of cell proliferation after etanercept alone. By contrast, in animals preconditioned with retrorsine and partial hepatectomy, cell transplantation after etanercept pretreatment significantly accelerated liver repopulation compared with control rats. We concluded that TNF-α played a major role in orchestrating cell transplantation-induced inflammation through regulation of multiple cytokines/chemokines/receptor expression. As TNF-α antagonism by etanercept decreased transplanted cell clearance, improved cell engraftment and accelerated liver repopulation, this pharmacological approach to control hepatic inflammation will help optimize clinical strategies for liver cell therapy.

    Full Text Available Abstract Background Portal vein thrombosis is a frequent complication in end-stage cirrhosis with a considerable peri-operative risk for liver transplant candidates. We aimed to characterize the pre-transplant portal vein thrombosis in a cohort of liver transplant recipients, and to identify independent risk factors for this complication. Methods 380 consecutive primary orthotopic liver transplants were performed in the Digestive Surgery Department of “12 de Octubre” Hospital (Madrid, Spain, between January 2001 and December 2006. The main risk factors considered were smoking, obesity, metabolic disorders, previous immobility, surgery or trauma, nephrotic syndrome, associated tumor, inflammatory disease, neoplasm myeloprolipherative. Furthermore we have reported genetic thrombophilia results for 271 recipients. Results Sixty-two (16.3% patients developed pre-transplant portal vein thrombosis and its presence had no impact in the overall survival of liver recipients. Obesity was the only independent risk factor for pre-transplant portal vein thrombosis. Conclusion We recommend close control of cardiovascular factors in patients with liver cirrhosis in order to avoid associated thrombosis.

    During the 1990s, gram-positive bacteria emerged as major pathogens after liver transplantation. We sought to determine whether the pathogens associated with bacteremias in liver transplant recipients have changed. Patients included 233 liver transplant recipients transplanted between 1989 and 2003. The proportion of all infections due to bacteremias increased significantly over time (P gram-negatives increased from 25% in the period of 1989-1993 to 51.8% in 1998-03, that of gram-positive bacteria decreased from 75% in the period of 1989-93 to 48.2% in the period of 1998-2003. Methicillin-resistant Staphylococcus aureus (MRSA), Klebsiella pneumoniae, and Pseudomonas aeruginosa were the most frequent pathogens in bacteremic patients. The incidence of bacteremias due to MRSA and Pseudomonas aeruginosa has remained unchanged (P gram-negative bacteria, particularly Klebsiella pneumoniae has increased (P =.02). Klebsiella pneumoniae isolates in the current quartile were not clonally related. In conclusion, bacteremias as a proportion of all infections in liver transplant recipients have increased significantly over time, due in part to a decline in infections due to other major pathogens, e.g., fungi, primarily Candida species, and CMV. Gram-negative bacteria have emerged as predominant pathogens in bacteremic liver transplant recipients.

    Liver transplants, originally obtained from deceased donors, can now be harvested from living donors as well. This technique, called living-donor liver transplantation (LDLT), provides an effective alternative means of liver transplantation and is a method of expanding the donor pool in light of the demand and supply imbalance for organ transplants. Imaging plays an important role in LDLT programmes by providing robust evaluation of potential donors to ensure that only anatomically suitable donors with no significant co-existing pathology are selected and that crucial information that allows detailed preoperative planning is available. Imaging evaluation helps to improve the outcome of LDLT for both donors and recipients, by improving the chances of graft survival and reducing the postoperative complication rate. In this review, we describe the history of LDLT and discuss in detail the application of imaging in donor assessment with emphasis on use of modern computed tomography (CT) and magnetic resonance imaging (MRI) techniques

  14. Listeria monocytogenes following orthotopic liver transplantation: Central nervous system involvement and review of the literature

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Listeria monocytogene is a well-recognized cause of bacteremia in immunocompromised individuals, including solid organ transplant recipients, but has been rarely reported following orthotopic liver transplantation. We describe a case of listeria meningitis that occurred within a week after liver transplantation. The patient developed a severe headache that mimicked tacrolimus encephalopathy, and was subsequently diagnosed with listeria meningitis by cerebrospinal fluid culture. The infection was successfully treated with three-week course of intravenous ampicillin. Recurrent hepatitis C followed and was successfully treated with interferon alfa and ribavirin. Fourteen cases of listeriosis after orthotopic liver transplantation have been reported in the English literature. Most reported cases were successfully treated with intravenous ampicillin. There were four cases of listeria meningitis, and the mortality of them was 50%.Early detection and treatment of listeria meningitis are the key to obtaining a better prognosis.

    To highlight the rare yet devastating complication of CMV retinitis in a minimally immunosuppressed patient eight yr after liver transplantation for biliary atresia. A 22-yr-old female status-post deceased donor liver transplant at age 13 secondary to biliary atresia receiving single agent immunosuppression presented with acute, unilateral, profound decrease in visual acuity. The patient was diagnosed to have acute onset unilateral CMV retinitis. Retinal examination uncovered classical appearance of retinal whitening and retinal hemorrhages with extensive macular involvement. CMV retinitis can occur as a late complication following liver transplantation. Additionally, CMV retinal disease can occur in the absence of laboratory evidence of CMV infection and independent of additional clinical features suggesting CMV disease. Currently, there is no standard of care regarding screening for CMV retinitis, and thus, further research is needed to define the need for potential changes in current clinical practices and post-transplant screening protocols. © 2012 John Wiley & Sons A/S.

    We sought to analyse the effect of pretransplant diabetes on post-operative outcomes and resource utilization following liver transplantation. A retrospective cohort study was designed using a linkage between the University HealthSystem Consortium and Scientific Registry of Transplant Recipients databases. We identified 12 442 patients who underwent liver transplantation at 63 centres from 2007-2011 and separated cohorts of patients with diabetes (n = 2971; 24%) and without (n = 9471; 76%) at the time of transplant. We analysed transplant related outcomes and short-term survival. Diabetic recipients were more likely to be male (70% vs 67%), non-white (32% vs 26%), older (age ≥60; 41% vs 28%), and have a higher BMI (29 vs 27; P diabetic patients were on haemodialysis (10% vs 7%), had cirrhosis caused by NASH (24% vs 9%; P 1.49; 46% vs 42%; P diabetic recipients had longer hospital length of stay (10 vs 9 days), higher peri-transplant mortality (5% vs 4%) and 30-day readmission rates (41% vs 37%), were less often discharged to home (83% vs 87%; P diabetics ($105 078 vs $100 624, P diabetic recipients were less likely discharged home following transplant (75% vs 82%, P diabetes is associated with inferior post-operative outcomes and increased resource utilization after liver transplantation. © 2014 John Wiley & Sons A/S.

    2015-01-01

    Full Text Available Liver transplantation is the only available treatment for some patients with end-stage liver disease. Despite reduction in mortality rates due to advances related to surgical techniques, intensive medical management and immunosuppressive therapy, invasive fungal infections remain a serious complication in orthotopic liver transplantation. We report the case of an 18-year-old male diagnosed with autoimmune cirrhosis in 2009 who was assessed and listed for liver transplantation for massive variceal hemorrhage. One year after listing a successful orthotopic liver transplantation was performed. Uneventful early recovery was achieved; however, he developed pulmonary and neurological Aspergillus infection 23 and 40 days after surgery, respectively. Antibiotic therapy with voriconazole and amphotericin was started early, with no major response. Neuroimaging revealed multiple right frontal and right parietal lesions with perilesional edema; surgical management of the brain abscesses was performed. A biopsy with periodic acid-Schiff and Gomori stains revealed areas with mycotic microorganisms morphologically consistent with Aspergillus, later confirmed by culture. The patient developed necrotizing encephalitis secondary to aspergillosis and died. Necrotizing encephalitis as a clinical presentation of Aspergillus infection in an orthotopic liver transplant is not common, and even with adequate management, early diagnosis and prompt antifungal treatment, mortality rates remain high.

    AIM: The aim of this study was to describe an auxiliary combined liver-small bowel transplantation model with the preservation of duodenum, head of pancreas and hepatic biliary system in pigs. The technique, feasibility, security and immunosuppression were commented.METHODS: Forty outbred long-white pigs were randomized into two groups, and the auxiliary composite liver/small bowel allotransplantations were undertaken in 10 long-white pigs in each group with the recipient liver preserved.Group A was not treated with immunosuppressive drugs while group B was treated with cyclosporine A and methylprednisolone after operation. The hemodynamic changes and amylase of body fluid (including blood, urine and abdominal drain) were analyzed.RESULTS: The average survival time of the animals was 10±1.929 d (6 to 25 d) in group A while more than 30 d in group B. The pigs could tolerate the hemodynamic fluctuation during operation and the hemodynamic parameters recovered to normal 2 h after blood reperfusion. The transient high amylase level was decreased to normal one week after operation and autopsy showed no pancreatitis.CONCLUSION: Auxiliary en-bloc liver-small bowel transplantation with partial pancreas preservation is a feasible and safe model with simplified surgical techniques for composite liver/small bowel transplantation. This model may be used as a preclinical training model for clinical transplantation method, clinical liver-small bowel transplantation related complication research, basic research including immunosuppressive treatment, organ preservation, acute rejection, chronic rejection, immuno-tolerance and xenotransplantation.

    Racial disparity in access to liver transplantation among African Americans (AA) compared to Caucasians (CA) has been well described. The aim of this investigation was to examine the presentation of AA liver transplant recipients in a socioeconomically challenged region. 680 adult liver transplant candidates and 233 resultant recipients between 2007 and 2015 were analyzed using univariate and multivariate analyses to evaluate factors significant for transplantation. Percentages of wait list patients transplanted were similar between CA and AA (34.9% vs. 32.2%, p = 0.5205). AA were younger (50.4 ± 1.8 vs. 56.3 ± 0.7 yrs, p = 0.0003) with higher average MELD scores (22.9 ± 1.6 vs. 19.4 ± 0.7, p = 0.0230). Overall patient mortality was similar (AA 22.7% vs. CA 26.3%, p = 0.5931). A multiple linear regression showed that male gender was strongly associated with transplantation. Equal access to liver transplantation remains challenging for racial minorities. At our institution, AA were accepted and transplanted at an equivalent rate as CA despite a higher AA population, HCV rate and diagnosed HCC. AA were younger and sicker at the time of transplant, but overall had similar outcomes compared to CA. Our study highlights the need for studies to delineate the underpinnings of disparity in transplantation access. Copyright © 2017 International Hepato-Pancreato-Biliary Association Inc.

    Piggyback orthotopic liver transplantation (LTx) has permitted the elimination of extra-corporeal venovenous bypass. In some instances, an internal temporary portocaval shunt has to be constructed in order to prevent hemodynamic instability. We describe a technique in which a donor iliac vein graft is used to bridge the distance between the portal vein and vena cava in cases where a direct shunt cannot be constructed. This technique can be applied to liver Tx as well as to liver and small bowel Tx.

    Full Text Available INTRODUCTION: Liver transplantation is the best therapeutic option for end-stage liver disease. Non-selective beta-blocker medications such as propranolol act directly on the cardiovascular system and are often used in the prevention of gastrointestinal bleeding resulting from HP. The effects of propranolol on cardiovascular system of cirrhotic patients during liver transplantation are not known. OBJECTIVE: Evaluate the influence of propranolol used preoperatively on cardiac index during the anhepatic phase of liver transplantation. METHOD: 101 adult patients (73 male [72.2%] who underwent cadaveric donor orthotopic liver transplantation by piggyback technique with preservation of the retrohepatic inferior vena cava performed at Hospital das Clinicas, Federal University of Minas Gerais were evaluated. There was no difference in severity between groups by the MELD system, p = 0.70. The preoperative use of propranolol and the cardiac index outcome were compared during the anhepatic phase of liver transplantation in 5 groups (I: increased cardiac index, II: cardiac index reduction lower than 16%, III: cardiac index reduction equal to or greater than 16% and less than 31%, IV: cardiac index reduction equal to or greater than 31% and less than 46%, V: cardiac index reduction equal to or greater than 46%. RESULTS: Patients in group I (46.4% who received propranolol preoperatively were statistically similar to groups II (60%, III (72.7%, IV (50% and V (30.8%, p = 0.57. CONCLUSION: The use of propranolol before transplantation as prophylaxis for gastrointestinal bleeding may be considered safe, as it was not associated with worsening of cardiac index in anhepatic phase of liver transplantation.

    Although many human inflammatory and autoimmune diseases were previously considered to be mediated by T helper type 1 (Th1) cells, the recently described Th17 cells play dominant roles in several of these diseases. We and others speculated that allograft rejection after organ transplantation may also involve Th17 cells. Episodes of acute rejection occur in 30% of liver transplants. This study aimed to determine the frequency of circulating Th17 cells in patients who had received liver transplants for benign end-stage liver disease and to identify any association between acute rejection episodes and levels of Th17 cells in the peripheral blood. A prospective study compared Th17 cells from 76 consecutive benign end-stage liver disease patients who had undergone orthotopic liver transplantation from 2007 to 2011 with those from 20 age-matched healthy individuals. Peripheral blood samples were collected at different time points within one year after transplant. Blood samples and liver biopsies were also collected at the diagnosis of acute rejection. Percentages of circulating CD4+IL-17+ cells were measured by flow cytometry. The transplant patients were classified into two groups: a rejection group consisting of 17 patients who had an episode of acute rejection, and a non-rejection group comprising the remaining 59 patients with no acute rejection episodes. Percentages of circulating Th17 cells were compared between the two groups and controls. The levels of circulating CD4+IL-17+ T cells in the rejection group were higher during acute rejection than those in the non-rejection group (2.56+/-0.43% versus 1.79+/-0.44%, Pblood was positively correlated with the rejection activity index (r=0.79, P=0.0002). Circulating Th17 cells may be useful as a surrogate marker for predicting acute rejection in liver transplant recipients.
