Xiong Z, Yang Z, Wang Q, Li T. Global research hotspots and trends of acute rejection after liver transplantation from 1988 to 2022: a bibliometric analysis. Front Pharmacol 2024; 15:1357468. [PMID: 38694927 PMCID: PMC11061468 DOI: 10.3389/fphar.2024.1357468] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2023] [Accepted: 04/05/2024] [Indexed: 05/04/2024] Open
Abstract
Background: Acute rejection (AR) is the predominant form of rejection observed in liver transplantation and plays a crucial role in transplant immunology. This study aims to utilize bibliometric analysis to understand the status quo, hotspots, and future trends of research on AR after liver transplantation. Methods: We searched the Web of Science Core Collection (WoSCC) for studies on AR after liver transplantation published from 1988 to 2022. The Bibliometric Online Analysis Platform, VOSviewer, and CiteSpace were used for analysis of all extracted publications. Results: This study included 2,398 articles published in 456 journals by 12,568 authors from 1,965 institutions in 55 countries/regions. The United States and its affiliated institution, the University of Pittsburgh, were the most productive contributors. Transplantation (n = 12,435) was the most frequently cited journal. Neuhaus P (n = 38) was the highest output author, and Demetris AJ (n = 670) was the most co-cited author. The research hotspots of AR after liver transplantation include pathogenesis, immunosuppressive therapy, and prognosis. Emerging research directions include regulatory T cells, immunosuppression minimization, intra-patient variability (IPV) of tacrolimus, and novel non-invasive diagnostic markers. Conclusion: Our study utilized bibliometric methods to analyze the study of AR after liver transplantation over the past 35 years. With the prolonged survival of liver transplant recipients, the most active areas currently focus on individualized treatment and improving patient prognosis. Minimizing adverse reactions to immunosuppressive therapy while simultaneously avoiding an increase in the risk of AR remains a future research focus.

Abstract
INTRODUCTION Liver transplant recipients receive many medications for anti-rejection, infection prophylaxis, and treatment of comorbidities. Most of them also receive medications from multiple sources. Therefore, these patients are prone to drug-related problems (DRPs) and medication errors. This study aimed to study the effect of medication reconciliation (MR) and pharmaceutical care processes by transplant pharmacists in the post-liver transplant clinic. METHODS This study was a retrospective study in Siriraj Liver Transplant Center, Mahidol University, Thailand. Patients who received pharmaceutical care from transplant pharmacists were compared before and after the implementation of MR (October 2020-September 2021 vs October 2021-September 2022) to assess the prevalence of medication errors and identify DRPs between the 2 groups. RESULTS Before implementation of MR, in a total of 797 visits, 69 medication errors (8.7%) were found. The most errors were medication omissions (44.9%, n = 31). After the implementation of MR, in a total of 879 visits, 44 medication errors (5.0%) were found. Most were medication omission and incorrect strength (31.8%, n = 14). Medication errors significantly decreased by 36.2% (P < .001) after the implementation of MR. Regarding DRPs, transplant pharmacists could significantly detect more DRPs after implementation of MR, 66 DRPs before implementation of MR vs 111 DRPs after implementation of MR (P < .001). The most DRPs were non-adherence (34 vs 41). CONCLUSIONS MR can reduce medication errors and assist transplant pharmacists in identifying DRPs that will lead to active intervention by attending physicians and/or patients to improve medication management and patient safety in post-liver transplant care.

Abstract
Background and aims Liver transplant surgery has been performed in India for the last 25 years. We aimed to analyse the trends, characteristics, and key elements in the field of liver transplantation research from India. Methods On April 23, 2023, we conducted a search of the Scopus database for the literature on liver transplantation research, using a well-defined search strategy. MS Excel and VOS viewer software programs were used to examine the articles for organisation, author, journal, keywords, and high-cited literature. Results This analysis examined a total of 556 papers, which constituted only a 1.55% share of the global output. These papers involved 442 organizations, 1575 authors, and 147 journals. External funding was received in 4.13% and 23.56% were involved in international collaboration. Three Delhi-NCR organizations, namely the Medanta-The Medicity (n = 63), Institute of Liver & Biliary Sciences (n = 60), and Indraprastha Apollo Hospital (n = 48) led in publication productivity. M. Rela (n = 90) and A.S. Soin (n = 63) were the leading authors in publication productivity, while S. Sudhindran and P. Bhangui were the most impactful authors. Liver Transplantation (n = 96) and Journal of Clinical & Experimental Hepatology (n = 65) published the maximum number of these papers, whereas, Annals of Surgery and Journal of Hepatology led in the citation impact per paper. The most significant keywords were "Liver Transplantation" (n = 484), and "Living Donor" (n = 254). Only 1.80% (n = 10) of the papers were highly cited papers that received 50 to 142 citations and they together registered 69.9 citations per paper. Conclusion Although the number of publications on liver transplantation from India started growing recently, it forms only 1.55% of the global report. There is an unmet need to increase government-supported research and multicenter collaborative studies at national and international levels for high-quality patient care.

Abstract
IMPORTANCE Transplantation has transformed into a burgeoning field that is rapidly evolving to optimize organ distribution and survival outcomes. The years since 2012 (the last comprehensive study) have seen changes in transplantation, such as advances in immunotherapy and novel indices, that necessitate an updated analysis of survival benefit. DESIGN Our goal was to determine the survival benefit for solid-organ transplants in the United Network for Organ Sharing (UNOS) database for a three decade period and provide updates on advancements since 2012. Our retrospective analysis examined data containing U.S. patient records from September 1, 1987, to September 1, 2021. RESULTS We found that 3,430,272 life-years were saved over our transplant period (4.33 life-years saved per patient); kidney-1,998,492 life-years; liver -767,414; heart-435,312; lung-116,625; pancreas-kidney-123,463; pancreas-30,575; intestine-7901. After matching, 3,296,851 life-years were saved. Life-years saved and median survival increased for all organs between 2012 and 2021. Compared to 2012, median survival increased in kidney (from 12.4 to 14.76 years), liver (from 11.6 to 14.59), heart (9.5 to 11.73), lung (5.2 to 5.63), pancreas-kidney (from 14.5 to 16.88), pancreas (from 13.3 to 16.10). When compared to 2012, the percent transplanted increased in kidney, liver, heart, lung, and intestine, while pancreas-kidney and pancreas show decreased percent transplanted. CONCLUSION Our study underscores the tremendous survival benefits of solid organ transplantation (over 3.4 million life-years saved) and shows improvements since 2012. Our study also highlights areas of transplantation, notably pancreas transplants, that may necessitate reinvigorated attention.

Abstract
Liver disease is increasing in incidence and is the third most common cause of premature death in the United Kingdom and fourth in the United States. Liver disease accounts for 2 million deaths globally each year. Three-quarters of patients with liver disease are diagnosed at a late stage, with liver transplantation as the only definitive treatment. Thomas E. Starzl performed the first human liver transplant 60 years ago. It has since become an established treatment for end-stage liver disease, both acute and chronic, including metabolic diseases and primary and, at present piloting, secondary liver cancer. Advances in surgical and anaesthetic techniques, refined indications and contra-indications to transplantation, improved donor selection, immunosuppression and prognostic scoring have allowed the outcomes of liver transplantation to improve year on year. However, there are many limitations to liver transplantation. This review describes the milestones that have occurred in the development of liver transplantation, the current limitations and the ongoing research aimed at overcoming these challenges.

Abstract
Spain has the highest rates of liver transplantation (LT) per million inhabitants in the world, with the profiles of both donors and recipients in Asturias, a region in northern Spain, being different from the rest of the country. The main goal of this study was to carry out a preliminary analysis of the characteristics of LT recipients in Asturias, as well as of the basic characteristics of surgery and the postoperative period, and to discuss whether the results obtained in this study were comparable to what is described in the literature. This was a retrospective, descriptive, cross-sectional study, analyzing the LT carried out in a reference center of Asturias between 2002 and 2017. Relative and absolute frequency distributions for qualitative variables are provided, as are position and dispersion measures for quantitative variables. Using the multivariate Cox regression model, the prognostic factors associated with overall survival were determined. A total of 533 LTs were analyzed; 431 were men and 102 were women. The mean age was 55.1 years, concentrated between 40 and 69 years for both genders. LT was performed for chronic parenchymal liver disease (mostly of alcoholic etiology) and the recipients underwent surgery in an advanced stage of liver disease. Of these recipients, 8.1% (43 patients) were retransplantions, 65.1% in the first year due to primary graft dysfunction and complete hepatic artery thrombosis. Most patients had presented a grade II of Clavien-Dindo as the most frequent complication. Biliary complications were found in 12.3% of patients, with the main cause of death in the first 30 days being instability in the 24 h after LT. The median survival of the group was 13 years, with a 5-year survival probability of 79.3% and a 10-year survival probability of 61.9%. In view of the analyzed series, it can be concluded that the most frequent recipient profile was a male patient (mean age 55 years), with a significant alcohol habit, who was overweight, with chronic parenchymal liver disease of alcoholic or viral etiology, and who had reached the Child C stage before LT. This study could lay the foundations for future studies, to complete this analysis with the characteristics of LT surgery, its postoperative period, and the follow-up after discharge, to obtain a broader view of LT recipients in this region.

Abstract
Purpose The objectives were to investigate the safety and efficacy of thermal ablation as an alternative to liver transplantation for hepatocellular carcinoma patients with clinically significant portal hypertension (CSPH). Materials and Methods From July 2016 to September 2019, hepatocellular carcinoma patients with CSPH treated by liver transplantation (N=37) or thermal ablation (N=114) were enrolled. Cumulative intrahepatic recurrence, overall survival and major complications were compared by propensity score matching. Results In the two matched groups, the 1-, 2-, and 3-year intrahepatic recurrence rates for the ablation group (22.3%, 50.0%, and 50.0%, respectively) were significantly higher than those for the transplantation group (4.5%, 4.5%, and 4.5%, respectively) (P=0.016). The 1-, 2-, and 3-year overall survival rates were comparable between the two groups [96.1%, 88.7%, and 88.7%, respectively (ablation group) vs. 84.6%, 76.2%, and 76.2%, respectively (transplantation group)] (P=0.07). The major complication rate for the ablation group [4.8% (3/62)] was significantly lower than that for the transplantation group [36.0% (9/25)] (P<0.001). Conclusions Thermal ablation is a safe and effective alternative for hepatocellular carcinoma patients with CSPH.

Abstract
BACKGROUND Liver transplantation is a life-saving treatment for end-stage pediatric liver failure. We aimed to present the results of pediatric liver transplants performed in our center in the last 11 years (between 2012 and March 2022) in association with prognostic factors affecting survival. METHODS Demographic characteristics, etiologic reasons, previous operations (Kasai procedure), morbidity, mortality, survival, and bilio-vascular complication rates were determined, and outcomes were evaluated. In the postoperative period, the duration of mechanical ventilation and intensive care unit stay and surgical and other complications were evaluated. Graft and patient survival rates were determined, and univariate and multivariate factors affecting these rates were evaluated. RESULTS In the last 10 years, 229 pediatric liver transplantaion (Pe-LT)/1513 adult liver taransplantation (Ad-LT) (21.35%) were performed in our center. This ratio (Pe-LT/Ad-LT ratio) is 1741/15,886 (10.95%) for our country. A total of 229 liver transplants were performed in 214 pediatric patients. Retransplantation was performed in 15 patients (6.55%). Cadaveric liver transplantation was performed in 9 patients. Graft survival rates were 87%, 83%, 78%, 78%, 78%, and 78% at <30 days, 30 to 90 days, 91 to 364 days, 1 to 3 years, and >3 years, respectively. Patient survival rates for <30 days, 30 to 90 days, 91 to 364 days, 1 to 3 years, and >3 years were 91.5%, 85.7%, 82%, 81.5%, and 81.5%, respectively. Our 5-year survival rates in metabolic diseases and the acute fulminant failure group are 93.8% and 100%, respectively. CONCLUSIONS The fact that the 1- and 5-year survival rates are the same shows that when patients overcome biliary vascular and infectious problems, their survival is prolonged.

Abstract
BACKGROUND Liver transplantation offers curative treatment to patients with acute and chronic end-stage liver disease. The impact of nutritional status on postoperative outcomes after liver transplantation remains poorly understood. The present study investigated the predictive value of radiologically assessed skeletal muscle index (SMI) and myosteatosis (MI) on postoperative outcomes. PATIENTS AND METHODS Data of 138 adult patients who underwent their first orthotopic liver transplantation were retrospectively analysed. SMI and MI in computer tomography (CT) scan at the third lumbar vertebra level were calculated. Results were analyzed for the length of hospitalisation and postoperative outcomes. RESULTS In 63% of male and 28.9% of female recipients, low SMI was found. High MI was found in 45(32.6%) patients. Male patients with high SMI had longer intensive care unit (ICU) stay (P < 0.025). Low SMI had no influence on ICU stay in female patients (P = 0.544), length of hospitalisation (male, P > 0.05; female, P = 0.843), postoperative complication rates (males, P = 0.883; females, P = 0.113), infection rate (males, P = 0.293, females, P = 0.285) and graft rejection (males, P = 0.875; females, P = 0.135). The presence of MI did not influence ICU stay (P = 0.161), hospitalization (P = 0.771), postoperative complication rates (P = 0.467), infection rate (P = 0.173) or graft rejection rate (P = 0.173). CONCLUSIONS In our study, changes in body composition of liver transplant recipients observed with SMI and MI had no impact on postoperative course after liver transplantation. CT body composition analysis of recipients and uniformly accepted cut-off points are crucial to producing reliable data in the future.

Current formulations of tacrolimus, such as Prograf® and Advagraf™, exhibit limitations in terms of pharmacokinetics and tolerability, related in part to suboptimal bioavailability. As dosing non-compliance can result in graft rejection, the once daily formulation of tacrolimus, Advagraf™, was developed (vs 2x/day Prograf®). Benefits of Advagraf™ are counterbalanced by delayed achievement of therapeutic trough levels and need for up to 50% higher doses to maintain Prograf®-equivalent troughs. Envarsus® is also a prolonged-release once-daily tacrolimus formulation, developed using MeltDose™ drug-delivery technology to increase drug bioavailability; improved bioavailability results in low patient drug absorption variability and less pronounced peak-to-trough fluctuations. In phase III de novo kidney transplant studies, Envarsus® proved non-inferior to twice-daily tacrolimus; however, no phase IV studies show superiority of Envarsus® vs Advagraf™ in de novo liver transplant (LTx) recipients. METHODS The EnGraft compares bioavailability and tests superiority of Envarsus® (test arm) versus Advagraf™ (comparator arm) in de novo LTx recipients. A total of 268 patients from 15 German transplant centres will be randomised 1:1 within 14 days post-LTx. The primary endpoint is dose-normalised trough level (C/D ratio) measured 12 weeks after randomisation. Secondary endpoints include the number of dose adjustments, time to reach first defined trough level and incidence of graft rejections. Additionally, clinical and laboratory parameters will be assessed over a 3-year period. DISCUSSION C/D ratio is an estimate for tacrolimus bioavailability. Improving bioavailability and increasing C/D ratio using Envarsus could reduce renal dysfunction and other tacrolimus-related toxicities; previous trials have shown that a higher C/D ratio (i.e. slower tacrolimus metabolism) is not only associated with improved renal function but also linked to reduced neurotoxic side effects. A higher C/D ratio could improve clinical outcomes for LTx recipients; EnGraft has begun, with one third of patients recruited by January 2022. TRIAL REGISTRATION This trial has been registered (4 May 2020) in the EU Clinical Trials Register, EudraCT-Nummer: 2020-000796-20. Additionally, this trial has been registered (22 January 2021) at ClinicalTrials.gov: NCT04720326. The trial received a favourable opinion from the concerned lead ethics committee at the University of Regensburg, under the reference 20-1842-112.

Abstract
The liver is one of the crucial organs of the body that performs hundreds of chemical reactions needed by the body to survive. It is also the largest gland of the body. The liver has multiple functions, including the synthesis of chemicals, metabolism of nutrients, and removal of toxins. It also acts as a storage unit. The liver has a unique ability to regenerate itself, but it can lead to permanent damage if the injury is beyond recovery. The only possible treatment of severe liver damage is liver transplant which is a costly procedure and has several other drawbacks. Therefore, attention has been shifted towards the use of stem cells that have shown the ability to differentiate into hepatocytes. Among the numerous kinds of stem cells (SCs), the mesenchymal stem cells (MSCs) are the most famous. Various studies suggest that an MSC transplant can repair liver function, improve the signs and symptoms, and increase the chances of survival. This review discusses the impact of combining stem cell therapy with nanotechnology. By integrating stem cell science and nanotechnology, the information about stem cell differentiation and regulation will increase, resulting in a better comprehension of stem cell-based treatment strategies. The augmentation of SCs with nanoparticles has been shown to boost the effect of stem cell-based therapy. Also, the function of green nanoparticles in liver therapies is discussed.

Abstract
In recent decades, important advances have been made in the field of liver transplantation. One of the major problems remaining in this area is the small number of donors. Thus, recent data bring multiple updates of the indications and contraindications of this therapeutic method. The main goal is to increase the number of patients who can benefit from liver transplantation, a therapeutic method that can improve life expectancy and the quality of life of patients with end-stage liver disease. Another goal in the management of these patients is represented by the optimal care of those on the waiting list during that period. A multidisciplinary team approach is necessary to obtain the best results for both the donor and the recipient.

Abstract
INTRODUCTION Infantile oxalosis is the most severe form of primary hyperoxaluria type 1 (PH1), with onset of end-stage kidney disease (ESKD) during infancy. We aimed to analyze the outcome of these patients as our current understanding is limited owing to a paucity of reports. METHODS A retrospective registry study was conducted using data from the OxalEurope registry. All PH1 patients with ESKD onset at age <1 year were analyzed. RESULTS We identified 95 patients born between 1980 and 2018 with infantile oxalosis. Median (interquartile range [IQR]) age at ESKD was 0.4 (0.3-0.5) year. There were 4 patients diagnosed by family screening who developed ESKD despite early diagnosis. There were 11 patients who had biallelic missense mutations associated with vitamin B6 responsiveness. Of 89 patients, 27 (30%) died at a median age of 1.4 (0.6-2.0) years (5-year patient survival of 69%). Systemic oxalosis was described in 54 of 56 screened patients (96%). First transplantation was performed at a median age of 1.7 (1.3-2.9) years. In 42 cases, this procedure was a combined liver-kidney transplantation (LKTx), and in 23 cases, liver transplantations (LTx) was part of a sequential procedure. Survival rates of both strategies were similar. Patient survival was significantly higher in patients born after 2000. Intrafamilial phenotypic variability was present in 14 families of patients with infantile oxalosis. CONCLUSION Nearly all screened patients with infantile oxalosis developed systemic disease. Mortality is still high but has significantly improved over time and might further improve under new therapies. The intrafamilial phenotypic variability warrants further investigation.

Abstract
Liver transplantation is currently the only effective treatment for patients with end-stage liver disease; however, donor liver scarcity is a notable concern. As a result, extensive endeavors have been made to diversify the source of donor livers. For example, the use of a decellularized scaffold in liver engineering has gained considerable attention in recent years. The decellularized scaffold preserves the original orchestral structure and bioactive chemicals of the liver, and has the potential to create a de novo liver that is fit for transplantation after recellularization. The structure of the liver and hepatic extracellular matrix, decellularization, recellularization, and recent developments are discussed in this review. Additionally, the criteria for assessment and major obstacles in using a decellularized scaffold are covered in detail.

Living-Donor Liver Transplant in Oman: A Quantitative Cross-Sectional Study of Donors' Experiences and Challenges. J Transplant 2021; 2021:4251814. [PMID: 34820137 PMCID: PMC8608518 DOI: 10.1155/2021/4251814] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2021] [Revised: 10/07/2021] [Accepted: 10/22/2021] [Indexed: 11/30/2022] Open
Abstract
Background In Oman, the first liver transplant was performed at the Royal Hospital (RH) in September 2017. Since then, thirteen cases have been operated on at the RH. All of these cases were living-donor liver transplants (LDLT), and the remaining cases were treated in India with a total of approximately 193 recipients. To provide an in-depth overview of donor experiences, challenges, and perceptions, a cross-sectional study was conducted. Methods A cross-sectional study was conducted at one tertiary hospital in 2019. The survey was designed to collect data composed of closed and open-ended questions to reveal a thorough knowledge of the topic. Results A total of 50 of 120 donors responded to the survey with male dominance in the sample (68%) and 64% were aged 28 to 38 years. 66% of the respondents came to know about the donation through hospital staff. Interestingly, respondents (n = 8/12) who reported that fear of operation is the cause that prevents people from donating are among the male gender, while more men believe that the main cause is lack of knowledge. 90% of the respondents felt satisfied after donation. More men reported ambiguous feelings before donation. Moreover, married donors reported ambiguous feelings before donation (p = 0.008). The younger age group reported anxiety and doubt as a challenge through their donation experience. Conclusion This study revealed that donors have a positive feeling after donating as they have saved a life, as well as being empowered by family and community. The donors encourage individuals to donate a portion of their liver. Some crucial questions arose, such as anxiety before surgery, ambiguous feelings before surgery, and fatigue after surgery. These findings underscore the importance of a holistic approach that would enable donors to be well informed prior to surgery.

Abstract
BACKGROUND Immunosuppressive drugs have important role in transplant of solid grafts, it aim avoid episodes of acute and chronic rejection and improving graft survival and patient survival. In Brazil, in 2016, liver transplantation was the third most frequent, with 1,880 transplants performed, of which 150 in Rio Grande do Sul. Several studies evaluated the association between variability in blood levels of immunosuppressive tacrolimus and late acute cellular graft rejection. OBJECTIVE To investigate the association of tacrolimus blood levels with clinical outcomes late acute cellular rejection, death, patient survival and graft survival in patients undergoing liver transplantation. METHODS This is a retrospective longitudinal study including patients submitted to adult liver transplantation by the Liver Transplantation Group in the Santa Casa de Misericórdia Hospital of Porto Alegre, from January 2006 to January 2013, and who used tacrolimus as immunosuppressive therapy. RESULTS Of the 127 patients included in the study, the majority were male (70.1%), 52-60 years old (33.9%) at the transplant. The most frequent causes of liver transplantation in this series were hepatitis C virus and hepatocellular carcinoma (24.4%) and alcohol (15.7%). Thirteen patients had late acute cellular rejection (10.2%); of these, three had two episodes. Regarding severity classification, seven patients had mild late acute cellular rejection. The mean time of rejection after liver transplantation was 14 months (ranging from 8 to 33 months). Overall survival was 8.98 years. Regarding tacrolimus blood levels, 52 patients with a variation ≥2 standard deviations were identified. Of these patients, eight had rejection; however, the association was not significant (P=0.146). A significant association was found between variation ≥2 standard deviations in tacrolimus blood levels and death (P=0.023) and survival (P=0.019). Regarding 5-year follow-up of graft survival, being two standard deviations above increases by 2.26 times the risk of transplanted graft loss, and for each unit of increase of standard deviation of tacrolimus blood levels there is a two-fold increase in the risk of graft loss in 5 years. CONCLUSION Increased risk of graft loss associated with increased standard deviations of tacrolimus blood levels may indicate the need for more rigorous and prospective monitoring of tacrolimus blood levels.

Abstract
For many individuals with end-stage liver disease, the only treatment option is liver transplantation. However, liver transplant rejection is observed in 24%-80% of transplant patients and lifelong drug regimens that follow the transplant procedure lead to serious side effects. Furthermore, the pool of donor livers available for transplantation is far less than the demand. Well-characterized and physiologically relevant models of liver transplantation are crucial to a deeper understanding of the cellular processes governing the outcomes of liver transplantation and serve as a platform for testing new therapeutic strategies to enhance graft acceptance. Such a model has been found in the rat transplant model, which has an advantageous size for surgical procedures, similar postoperative immunological progression, and high genome match to the human liver. From rat liver transplant studies published in the last 5 years, it is clear that the rat model serves as a strong platform to elucidate transplant immunological mechanisms. Using the model, we have begun to uncover potential players and possible therapeutic targets to restore liver tolerance and preserve host immunocompetence. Here, we present an overview of recent literature for rat liver transplant models, with an aim to highlight the value of the models and to provide future perspectives on how these models could be further characterized to enhance the overall value of rat models to the field of liver transplantation.

Abstract
Liver diseases have become an increasing health burden and account for over 2 million deaths every year globally. Standard therapies including liver transplant and cell therapy offer a promising treatment for liver diseases, but they also suffer limitations such as adverse immune reactions and lack of long-term efficacy. Artificial cells that mimic certain functions of a living cell have emerged as a new strategy to overcome some of the challenges that liver cell therapy faces at present. Artificial cells have demonstrated advantages in long-term storage, targeting capability, and tuneable features. This article provides an overview of the recent progress in developing artificial cells and their potential applications in liver disease treatment. First, the design of artificial cells and their biomimicking functions are summarized. Then, systems that mimic cell surface properties are introduced with two concepts highlighted: cell membrane-coated artificial cells and synthetic lipid-based artificial cells. Next, cell microencapsulation strategy is summarized and discussed. Finally, challenges and future perspectives of artificial cells are outlined.

Abstract
Lung infection (LI) often occurs in patients with liver transplantation (LT). This meta-analysis was conducted to determine the risk factors associated with LI after LT. We retrieved relevant research published as of February 2020 from eight electronic databases. The studies were reviewed against the inclusion and exclusion criteria. The Z test was used to determine the combined odds ratio (OR) or the standardized mean difference (SMD) of the risk factors. We used the OR and its corresponding 95% confidence interval (CI) or the SMD and its corresponding 95% CI to identify significant differences in risk factors. A total of nine studies were included, comprising a total of 1624 recipients. Six risk factors associated with LI were identified after LT: Model for end-stage liver disease score (MELD score) (SMD = 0.40), Child-Pugh class C (OR = 3.00), intensive care unit (ICU) hospital stay (SMD = 1.35), mechanical ventilation (SMD = 1.03), bilirubin (SMD = 0.39), and atelectasis (OR = 7.28). Although certain risk factors have been identified as important factors for LI after LT, which may provide a basis for clinical prevention, a well-designed prospective study should be conducted to validate the findings of this study.

Abstract
OBJECTIVES Autoimmune hepatitis (AIH) is a form of severe hepatitis that can recur after orthotopic liver transplant (OLT). Presentation of AIH in patients with OLT who do not have a history of AIH is called de novo AIH (DNAIH). We evaluated the clinicopathologic characteristics of AIH and DNAIH. METHODS Clinicopathologic and outcome measures of 11 patients with recurrent AIH (RAIH) and 22 with DNAIH identified between 2000 and 2017 were compared. RESULTS Both cohorts showed female predominance. The mean clinical follow-up was 13 and 7.8 years in the in the RAIH and DNAIH groups, respectively (P = .1). Moderate portal inflammation was more common in patients with RAIH (64% vs 27%, P = .043). A trend was observed for more cases of DNAIH showing severe inflammation (36% vs 9%, P = .09) and submassive necrosis compared with RAIH (23% vs 0%, P = .086). A trend for more advanced fibrosis was also noted in the RAIH group (27% vs 5%, P = .059). Three patients with RAIH lost their grafts because of RAIH. Five-year disease-specific graft survival (GS) (P = .012) and overall GS (P = .015) were worse in patients with RAIH. Complement component 4d immunohistochemistry was positive in 2 patients with RAIH and 3 with DNAIH but showed no correlation with GS or other parameters. CONCLUSIONS RAIH seems to have a more aggressive clinical course than DNAIH and warrants closer clinical follow-up and aggressive treatment.

Abstract
Hepatitis C virus has historically been the leading indication for liver transplant, followed by nonalcoholic steatohepatitis (NASH) and alcoholic liver disease. Severe alcoholic hepatitis has become a growing indication for liver transplant, and overall alcohol use rates continue to increase in the United States. Rates of obesity and NASH in the United States continue to increase and are expected to place increasing demand on liver transplant infrastructure. In the current absence of robust pharmacologic therapy for NASH, the use of bariatric procedures and surgeries is being explored, as are other innovative approaches to curtail this upward trend.

Abstract
OBJECTIVE To evaluate factors related to liver graft survival with a focus on immunosuppressive schemes based on calcineurin inhibitors (tacrolimus or cyclosporine). METHODOLOGY This study was carried out through an open cohort constructed by deterministic and probabilistic matching through three databases of the SUS with assessment of liver graft survival from 2000 to 2015 in Brazil. From this first cohort, a second cohort was constructed by pairing 1: 1 to more precisely assess the effect of the immunosuppressive scheme on graft survival. The Kaplan-Meier method and was used to estimate the probability of survival. Cox's model of proportional risks was used to assess factors related to graft loss. RESULT We found 12,687 patients in the Full cohort and 470 patients in the Matched cohort. The overall graft survival rates at 1, 5, 10, and 16 years were 72.6, 63.3, 52.8, and 45.3%, respectively. Patients younger had a longer graft survival than older ones. In the Full cohort, male patients had a higher survival rate than female ones. Therapeutic schemes based on tacrolimus were more prevalent and had a better survival rate when compared to schemes that used cyclosporine. Tacrolimus without association with antiproliferative agents or rapamycin inhibitors was the therapeutic scheme associated with greater survival rate in both cohorts (HR = 0.81, 95% CI = 0.72-0.91), (HR = 0.50, 95% CI = 0.30-0.85). In addition, white-skinned patients had longer survival rate in both cohorts (HR = 0.55, 95% CI = 0.50-0.61 and HR = 0.50, 95% CI = 0.34-0.75). On the other hand, patients who a greater time ratio without using an immunosuppressant had lower graft survival rate (HR = 6.46, 95% CI = 5.05-8.27 and HR = 6.57, 95% CI = 2.66-16.22). CONCLUSION This 16-year cohort showed that the older age and the greater time ratio without using an immunosuppressant are risk factors for liver graft loss. White-skinned patients and tacrolimus-based regimens, especially tacrolimus without other immunosuppressants, are factors of better prognosis to the graft.

Abstract
BACKGROUND Secondary sclerosing cholangitis in critically ill patients (SSC-CIP) is an emerging disease with grim prognosis. OBJECTIVE Our aim was the analysis of prognostic factors, long-term outcome and risk of tumour development in SSC-CIP compared with primary sclerosing cholangitis (PSC) patients. METHODS Retrospective analysis between 2008 and 2018. RESULTS One hundred and eleven patients with SSC-CIP and 408 PSC patients were identified. Median orthotopic liver transplantation (OLT)-free survival was 16 months for SSC-CIP and 147 months for PSC (p < 0.001). OLT was performed in 18/111 SSC-CIP compared with 166/408 PSC patients (p < 0.001). Malignant tumours were detected in 17.9% of PSC patients (73/408) compared with 2.7% (3/111) in SSC-CIP (p < 0.001). In multivariate Cox regression analysis low levels of C-reactive protein (hazard ratio 4.687 (95% confidence interval (CI) 1.144-19.199, p = 0.032) were significantly associated with a prolonged survival whereas higher age (hazard ratio 0.488 (95% CI 0.23-1.038), p = 0.062) showed a trend for shorter survival in SSC-CIP. For PSC malignancies (hazard ratio 0.42 (95% CI 0.313-0.575), p < 0.001) and higher age (hazard ratio 0.709 (95% CI 0.544-0.922), p = 0.01) were associated with a shorter OLT-free survival. CONCLUSION SSC-CIP is characterized by acute onset of liver disease and poor prognosis but with lower tumour incidence compared with PSC.

Abstract
BACKGROUND Pediatric living donor liver transplantation (LDLT) has become the gold standard for patients with end-stage liver disease. With improvements in organ preservation, immunosuppression, surgical and anesthesia techniques, the survival rates and long-term outcomes of patients after LDLT have significantly improved worldwide. However, data on anesthetic management and postoperative survival rate of pediatric LDLT in China are rare.
AIM To review the status of pediatric LDLT in Shanghai and investigate the factors related to anesthetic management and survival rate in pediatric LDLT.
METHODS We conducted a retrospective observational study to investigate the status of pediatric LDLT in Shanghai by reviewing 544 records of patients who underwent pediatric LDLT since the first operation on October 21, 2006 until August 10, 2016 at Renji Hospital and Huashan Hospital.
RESULTS The 30-d, 90-d, 1-year, and 2-year survival rates were 95.22%, 93.38%, 91.36%, and 89.34%, respectively. The 2-year patient survival rate after January 1, 2011 significantly improved compared with the previous period (74.47% vs 90.74%; hazard ratio: 2.92; 95% confidence interval (CI): 2.16–14.14; P = 0.0004). Median duration of mechanical ventilation in the intensive care unit (ICU) was 18 h [interquartile range (IQR), 15.25–20.25], median ICU length of stay was 6 d (IQR: 4.80–9.00), and median postoperative length of stay was 24 d (IQR: 18.00–34.00). Forty-seven (8.60%) of 544 patients did not receive red blood cell transfusion during the operation.
CONCLUSION Pediatric end-stage liver disease (PELD) score, anesthesia duration, operation duration, intraoperative blood loss, and ICU length of stay were independent predictive factors of in-hospital patient survival. Pediatric end-stage liver disease score, operation duration, and ICU length of stay were independent predictive factors of 1-year and 3-year patient survival.

Abstract
Due to the growing number of liver transplantations (LTs), there is an increasing number of patients requiring retransplantation (reLT). Data on the use of grafts from extended criteria donors (ECD), especially donation after circulatory death (DCD), for reLT are lacking. We aimed to assess the outcome of patients undergoing reLT using a DCD graft in the Netherlands between 2001 and July 2018. Propensity score matching was used to match each DCD-reLT with three DBD-reLT cases. Primary outcomes were patient and graft survival. Secondary outcome was the incidence of biliary complications, especially nonanastomotic strictures (NAS). 21 DCD-reLT were compared with 63 matched DBD-reLTs. Donors in the DCD-reLT group had a significantly lower BMI (22.4 vs. 24.7 kg/m2 , P-value = 0.02). Comparison of recipient demographics and ischemia times yielded no significant differences. Patient and graft survival rates were comparable between the two groups. However, the occurrence of nonanastomotic strictures after DCD-reLT was significantly higher (38.1% vs. 12.7%, P-value = 0.02). ReLT with DCD grafts does not result in inferior patient and graft survival compared with DBD grafts in selected patients. Therefore, DCD liver grafts should not routinely be declined for patients awaiting reLT.

Abstract
BACKGROUND Observed long-term outcomes no longer reflect the survival trajectory facing pediatric liver transplant (LT) recipients today. We aimed to use national registry data and parametric models to project 20- and 30-year post-transplant outcomes for recently transplanted pediatric LT recipients. METHODS We conducted a retrospective cohort study of 13,442 first-time pediatric (age <18) LT recipients using 1987 to 2018 Scientific Registry of Transplant Recipients data. We validated the proposed method (ie, to project long-term patient and graft survival using parametric survival models and short-term data) in 2 historic cohorts (1987-1996 and 1997-2006) and estimated long-term projections among patients transplanted between 2007 and 2018. Projections were stratified by raft type, recipient age, and indication for transplant. RESULTS Parsimonious parametric models with Weibull distribution can be applied to post-transplant data and used to project long-term outcomes for pediatric LT recipients beyond observed data. Projected 20-year patient survival for pediatric LT recipients transplanted in 2007 to 2018 was 84.0% (95% confidence interval 81.5-85.8), compared to observed 20-year survival of 72.8% and 63.6% among those transplanted in 1997 to 2006 and 1987 to 1996, respectively. Projected 30-year survival for pediatric LT recipients in 2007 to 2018 was 80.1% (75.2-82.7), compared to projected 30-year survival of 68.6% (66.1-70.9) in the 1997 to 2006 cohort and observed 30-year survival of 57.5% in the 1987 to 1996 cohort. Twenty- and 30-year patient and graft survival varied slightly by recipient age, graft type, and indication for transplant. CONCLUSIONS Projected long-term outcomes for recently transplanted pediatric LT recipients are excellent, reflective of substantial improvements in medical care, and informative for physician-patient education and decision making in the current era.

Abstract
Advances in liver transplantation (LT) have allowed for expanded indications and increased surgical complexity. In select cases, additional surgery may be performed at time of LT rather than prior to LT due to the significant risks associated with advanced liver disease. We retrospectively studied the characteristics and outcomes of patients who underwent an additional planned abdominal or cardiac operation at time of LT between 2011–2019. An additional operation (LT+) was defined as a planned operation performed under the same anesthetic as the LT but not directly related to the LT. In total, 547 patients were included in the study, of which 20 underwent LT+ (4%). Additional operations included 10 gastrointestinal, 5 splenic, 3 cardiac, and 2 other abdominal operations. Baseline characteristics between LT and LT+ groups were similar. The median total operating time was significantly longer in LT+ compared to LT only (451 vs. 355 min, p = 0.002). Graft and patient survival, intraoperative blood loss, transfusion of blood products, length of hospital stay, and post-operative complications were not significantly different between groups. In carefully selected patients undergoing LT, certain additional operations performed at the same time appear to be safe with equivalent short-term outcomes and liver graft survival as those undergoing LT alone

Abstract
OBJECTIVES Liver transplant is a life-saving procedure for a variety of end-stage liver diseases. Cardiovascular disorders are among the leading cause of death among patients with end-stage liver disease and those undergoing liver transplant procedures. MELD-XI score is a newly developed score for mortality prediction in patients with end-stage liver failure. In this study, we investigated the relationships among MELD-XI score, total in-hospital mortality, and coronary artery disease severity and extent among patients with end-stage liver failure who were awaiting transplant. MATERIALS AND METHODS We retrospectively reviewed medical records of 121 patients with end-stage liver failure on transplant wait list. Study patients had undergone coronary angiography as part of pretransplant cardiac evaluation. We determined prevalence of coronary artery disease and Gensini score (which indicates extent of coronary artery disease) using coronary angiography and reviewed MELD-XI score and in-hospital mortality rates. We compared MELD-XI score and Gensini score in deceased and surviving patients and correlated both scores with mortality and with each other. RESULTS Of 121 patients, 79 (65.3%) were men; mean age of the study population was 59.6 ± 10.2 years. Twenty-eight patients (23.1%) had coronary artery disease, and 13 (10.7%) had severe coronary artery disease on coronary angiography. Twenty-three patients (19%) died while on the transplant wait list. Gensini score and MELD-XI scores were significantly higher in those who died (P < .05). MELD-XI score, but not Gensini score, was a significant independent predictor of death among patients awaiting liver transplant (hazard ratio = 1.35; 95% confidence interval, 1.04-1.78; P < .05). CONCLUSIONS MELD-XI score independently predicted in-hospital death among patients scheduled to undergo liver transplant. These patients also had increased prevalence and extent of coronary artery disease.

Abstract
Liver disease has been recognized in various forms for centuries. Incredible advances, however, have been made especially in the last 50 years, driven by improvements in histology, the development of immunostains, the development of high resolution imaging methods, improved biopsy and resection methods, and the emergence of the molecular era. With these tools, pathologists and their clinical and basic science colleagues moved from classifying liver disease using an observational, pattern-based approach to a refined classification of disease, one based on etiology for medical disease and tumor classification for neoplastic disease. Examples of liver specific diseases are used to illustrate these exciting advances. These impressive advances of the past provide the foundation for hope in the future, as liver pathology continues to play an important role in improving patient care through disease identification and classification and emerging roles in guiding therapy for cures.

Abstract
Although liver transplantation is a potential effective cure for patients with end-stage liver diseases, this strategy has several drawbacks including high cost, long waiting list, and limited availability of liver organs. Therefore, stem cell-based therapy is presented as an alternative option, which showed promising results in animal models of acute and chronic liver injuries. ABCB5+ cells isolated from skin dermis represent an easy accessible and expandable source of homogenous stem cell populations. In addition, ABCB5+ cells showed already promising results in the treatment of corneal and skin injury. To date, the effect of these cells on liver injury is still unknown. In the current study, sixteen weeks old Mdr2KO mice were i.v. injected with 500,000 ABCB5+ cells using different experimental setups. The effects of cellular therapy on inflammation, fibrosis, apoptosis, and proliferation were analyzed in the collected liver tissues. Toxicity of ABCB5+ cells was additionally investigated in mice with partial liver resection. In vitro, the fibrosis- and inflammatory-modulating effects of supernatant from ABCB5+ cells were examined in the human hepatic stellate cell line (LX-2). Cell injections into fibrotic Mdr2KO mice as well as into mice upon partial liver resection have no signs of toxicity with regard to cell transformation, cellular damage, fibrosis or inflammation as compared to controls. We next investigated the effects of ABCB5+ cells on established biliary liver fibrosis in the Mdr2KO mice. ABCB5+ cells to some extent influenced the shape of the liver inflammatory response and significantly reduced the amount of collagen deposition, as estimated from quantification of sirius red staining. Furthermore, reduced apoptosis and enhanced death compensatory proliferation resulted from ABCB5+ cell transformation. The stem cells secreted several trophic factors that activated TGF-β family signaling in cultured LX-2 hepatic stellate cells (HSCs), therewith shaping cell fate to an αSMAhigh, Vimentinlow phenotype. Taken together, ABCB5+ cells can represent a safe and feasible strategy to support liver regeneration and to reduce liver fibrosis in chronic liver diseases.

Abstract
Liver transplantation (LT) is considered the curative treatment option for selected patients who suffer from end-stage or acute liver disease or hepatic malignancy (primary). After LT, patients should be carefully monitored for complications that may appear, partially due to immunosuppressive therapy, but not entirely. Cardiovascular diseases are frequently encountered in patients with LT, being responsible for high morbidity and mortality. Patients with underlying cardiovascular and metabolic pathologies are prone to complications after the transplant, but these complications can also appear de novo, mostly associated with immunosuppressants. Metabolic syndrome, defined by obesity, hypertension, dyslipidemia, and hyperglycemia, is diagnosed among LT recipients and is aggravated after LT, influencing the long-term survival. In this review, our purpose was to summarize the current knowledge regarding cardiovascular (CV) diseases and the metabolic syndrome associated with LT and to assess their impact on short and long-term morbidity and mortality.

Abstract
Liver NRH is seen in all patients age; however, more frequently in those over the age of 60 years and associated with multiple systemic diseases. In liver allograft recipients, the development of DnNRH has been linked with the use of azathioprine or vascular abnormalities. We present the clinicopathologic characteristics of 17 pediatric patients who underwent liver transplantation and subsequently developed DnNRH. The patients were divided into early and late onset depending if DnNRH was diagnosed within or beyond 4 years after transplant. Eight patients (47%) presented as early onset, of which two had normal ultrasound at time of diagnosis. One patient (12.5%) with early onset lost the graft secondary to DnNRH. Nine patients (53%) presented as late onset, of which two (22%) had normal ultrasound at time of diagnosis. Two patients (25%) of the late onset lost their graft secondary to chronic rejection and DnNRH. Two patients (12%) died secondary to cytomegalovirus pneumonitis and pancolitis. Furthermore, both groups presented with symptoms differing from the adult population in prior studies and were not associated with the use of azathioprine or vascular abnormalities. Interestingly, episodes of acute cellular rejection were more common in the early-onset group compared to the late-onset group. In conclusion, DnNRH in the pediatric age group has a different clinical presentation, possibly reflecting a different pathogenesis compared to the adult population.

Abstract
OBJECTIVE To evaluate the effects of Kasai procedure (hepatic portoenterostomy) on living donor liver transplantation (LDLT) for children with biliary atresia (BA). METHODS From January 2006 to January 2014, 150 children with BA were treated with LDLT in China. The children were categorized into pre-Kasai and non-Kasai groups, based on whether they had previously undergone Kasai procedure. Clinical data were retrospectively analyzed, and the difference in postoperative survival was compared between the groups. Preoperative data, including height, weight, serum bilirubin, and pediatric end-stage liver disease score, and perioperative blood loss, operation duration, incidence of postoperative surgical complications including vascular complications, bile duct complications, lymphatic fluid leakage, and digestive tract fistula were compared between the groups. RESULTS In total, 89 and 61 children were categorized in the pre-Kasai and non-Kasai groups, respectively. The 1-, 6-, and 12-month survival was 97.8%, 95.4%, and 95.4% for the Kasai group, and 98.4%, 96.7%, and 96.7% for the non-Kasai group, respectively (P > 0.05). The differences in mean operation duration and mean blood loss, and the incidences of outflow tract obstruction, portal vein stenosis, hepatic artery thrombosis, bile duct complications, lymphatic fluid leakage, and digestive tract fistula were not statistically significant between the groups (P > 0.05). CONCLUSION Kasai procedure could effectively delay the requirement of liver transplantation. In light of previous findings that Kasai procedure could significantly improve the liver transplantation-free survival of children with BA, we suggest that Kasai procedure should be used as a first-line treatment method for this condition. TYPE OF STUDY Treatment Study. LEVEL OF EVIDENCE Level III.

Abstract
BACKGROUND Liver disease is one of the top causes of death globally. Although liver transplantation is a very effective treatment strategy, the shortage of available donor organs, waiting list mortality, and high costs of surgery remain huge problems. Stem cells are undifferentiated cells that can differentiate into a variety of cell types. Scientists are exploring the possibilities of generating hepatocytes from stem cells as an alternative for the treatment of liver diseases. METHODS In this review, we summarized the updated researches in the field of stem cell-based therapies for liver diseases as well as the current challenges and future expectations for a successful cell-based liver therapy. RESULTS Several cell types have been investigated for liver regeneration, such as embryonic stem cells, induced pluripotent stem cells, liver stem cells, mesenchymal stem cells, and hematopoietic stem cells. In vitro and in vivo studies have demonstrated that stem cells are promising cell sources for the liver regeneration. CONCLUSION Stem cell-based therapy could be a promising therapeutic method for patients with end-stage liver disease, which may alleviate the need for liver transplantation in the future.

Abstract
BACKGROUND Liver transplantation (LT) in elderly recipients is controversially discussed in the literature with only little data on long-term outcome available. We aimed to evaluate the safety and efficiency of LT in elderly recipients (>65 years). METHODS Between 1989-2016, 139 patients >65 years-old were listed for liver transplantation, and 76 (55%) were transplanted. Patient outcome and characteristics were evaluated separately for the time period before (1989-2004) and after (2005-2016) MELD-implementation. Post-transplant outcome was compared between the elderly cohort and LT-recipients aged 18-65 years (n = 1395). RESULTS Overall survival of patients >65 years was better in the MELD-era compared to the earlier period (1- and 5-year-survival: 73%, 60% vs. 69%, 37%, respectively; p = 0.055). The main differences between the two groups included higher recipient age (p = 0.001) and BMI (p = 0.001), higher donor age (p < 0.001), less need of intraoperative red blood cells (p = 0.008) and a lower number of postoperative rejections (p = 0.03) after 2004. Comparing the overall survival of patients transplanted in the MELD-era aged 18-65 years vs. >65 years displayed comparable 1- and 5 year-survival rates (81%, 68% vs. 73% and 60%, respectively, p = 0.558). CONCLUSION In the modern era, outcome of patients receiving LT with >65 years is comparable to <65 year-old patients. After careful evaluation, patients >65 years old should be considered for LT.

Abstract
Solid organ transplantation (SOT) has emerged from an experimental approach in the 20th century to now being an established and practical definitive treatment option for patients with end-organ dysfunction. The evolution of SOT has seen the field progress rapidly over the past few decades with incorporation of a variety of solid organs-liver, kidney, pancreas, heart, and lung-into the donor pool. New advancements in surgical technique have allowed for more efficient and refined multi-organ procurements with minimal complications and decreased ischemic injury events. Additionally, immunosuppression therapy has also seen advancements with the expansion of immunosuppressive protocols to dampen the host immune response and improve short and long-term graft survival. However, the field of SOT faces new barriers, most importantly the expanding demand for SOT that is outpacing the current supply. Allocation protocols have been developed in an attempt to address these concerns. Other avenues for SOT are also being explored to increase the donor pool, including split-liver donor transplants, islet cell implantation for pancreas transplants, and xenotransplantation. The future of SOT is bright with exciting new research being explored to overcome current obstacles.

Abstract
Aim Alcoholic liver disease (ALD) is the most common liver disease in the Western World. Liver transplantation (LT) is the treatment for end-stage ALD. However, many transplant centers are still reluctant to transplant these patients because of the risk of alcohol relapse, recurrence of the primary liver disease and associated post-transplant complications. We examined survival rate, prevalence of primary liver disease recurrence, re-transplantation and post-transplant complications among transplanted patients for alcoholic cirrhosis compared with those transplanted for viral cirrhosis. Methods data about patients transplanted for alcoholic and viral cirrhosis at the Gemelli Hospital from January 1995 to April 2016 were retrospectively collected. Survival rate was evaluated according to the Kaplan-Meier method. Recurrence was defined as histological evidence of primary liver disease. Data on the onset of complication, causes of death and graft failure after liver transplant were analyzed. Results There was no statistically significant difference regarding survival rate between the two groups. Only patients transplanted for viral cirrhosis presented with primary liver disease recurrence. There was a higher rate of cancer development in patients transplanted for alcoholic cirrhosis. Cancer was the major cause of death in this population. Risk factors associated with the onset of cancer were a high MELD score at the transplant time and smoking after transplantation. Conclusion ALD is a good indication for LT. Patients transplanted for alcoholic cirrhosis should receive regular cancer screening and should be advised against smoking. Short Summary No difference was found between patients transplanted for alcoholic cirrhosis and viral cirrhosis in term of survival rate. Only patients transplanted for viral cirrhosis presented primary liver disease recurrence. A higher rate of cancer development was found in patients transplanted for alcoholic cirrohosis. This complication was associated with post-trasplant smoking.

Domino Hepatocyte Transplantation: A Therapeutic Alternative for the Treatment of Acute Liver Failure. Can J Gastroenterol Hepatol 2018; 2018:2593745. [PMID: 30065914 PMCID: PMC6051327 DOI: 10.1155/2018/2593745] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/28/2018] [Revised: 05/25/2018] [Accepted: 05/31/2018] [Indexed: 12/26/2022] Open
Abstract
BACKGROUND AND AIMS Acute liver failure (ALF) is a severe syndrome with an elevated mortality rate, ranging from 40 to 80 %. Currently, liver transplantation is the only definitive treatment for these patients and new therapies aiming to treat ALF include artificial organs implant and stem cells therapy, for example. However, a major limitation of liver donors exists. Living donor liver transplantation (LDLT), split liver transplantation (SLT), and domino liver transplantation (DLT) are some of the available alternatives to treat ALF patients, but these do not reduce the number of patients on waiting lists. Herein, we discuss domino hepatocyte transplantation (DHT) using livers that would not meet transplantation criteria. METHODS We conducted a literature search on PubMed/Medline using acute liver failure, liver transplantation, hepatocyte transplantation, and domino liver transplantation as key words. RESULTS New sources of biochemically functional hepatocytes and therapeutic treatments, in parallel to organ transplantation, may improve liver injury recovery and decrease mortality rates. Moreover, the literature reports hepatocyte transplantation as a therapeutic alternative for organ shortage. However, a major challenge remains for a wide clinical application of hepatocytes therapy, i.e., the availability of sufficient amounts of cells for transplantation. Ideally, hepatocytes isolated from livers rejected for transplantation may be a promising alternative for this problem. CONCLUSION Our review suggests that DHT may be an excellent strategy to increase cell supplies for hepatocyte transplantation.

Abstract
INTRODUCTION Perioperative complications impose both a clinical and financial burden on patients and the healthcare system. This study sought to identify the frequency and economic impact of complications following orthotopic liver transplantation (OLT). METHODS The Premier Perspective® Hospital Database was queried for patients undergoing OLT between 2008 and 2015. Complications were identified by ICD-9 code and grouped by complication type. Complication frequency as well as impact on clinical and economic outcomes was calculated. Complication frequency and effect on cost were combined to determine the annual impact of each complication type on perioperative OLT cost. RESULTS Among 2747 OLT patients, the most common groups of complications following OLT were pulmonary, bleeding, and infectious. The complications with the greatest average effect on treatment-related costs were infectious, neurologic, deep vein thrombosis/pulmonary embolus, and hepatic arterial thrombosis. Infectious, pulmonary, and bleeding complications had the greatest annual effect on perioperative OLT cost. CONCLUSIONS Efforts focused on preventing coagulopathic bleeding, improving post-operative pulmonary toilet, and minimizing sources of infection can help improve the cost-effectiveness of OLT. Additionally, the combination of these cost data and systematized protocols can help insurers construct bundled payments for OLT that more accurately reflect the cost of perioperative transplant care.

Abstract
BACKGROUND The long-term efficacy of mesoatrial shunt (MAS) for Budd-Chiari syndrome (BCS) is not well studied. The purpose of our study was to investigate the long-term outcome and efficacy of MAS for BCS. METHODS We retrospectively evaluated 11 patients who underwent MAS for BCS from April 1986 to November 1995. Records of patients' clinical presentations, laboratorial investigation, Doppler duplex ultrasonography, radiologic image, and treatment outcomes were all retrieved and analyzed. RESULTS Follow-up intervals ranged from 1 year and 2 months to 30 years and 2 months (mean, 17 years and 8 months). Portal pressure decreased significantly from 35.72 ± 3.52 cm H2O to 27.86 ± 5.83 cm H2O post-MAS (P = 0.001). The 5-year, 10-year, and 20-year patency were 72.7%, 54.5%, 36.4%, respectively; 63.3% of patients had survived for more than 10 years and 45.5% for more than 20 years. A male has been alive with patent shunt for 28 years and 1 month. CONCLUSIONS The MAS with enforced rings is an effective therapeutic modality for BCS with cautious perioperative management.

Abstract
Deaths due to end-stage liver diseases are increasingly registered annually in the world. Liver transplantation is the ultimate treatment for end-stage liver diseases to date, which has been hampered by a critical shortage of organs. The potential of decellularized liver scaffolds (DLS) derived from solid organs as a three-dimensional platform has been evolved as a promising approach in liver tissue engineering for translating functional liver organ replacements, but questions still exist regarding the optimal cell population for seeding in DLS and the preparation of the DLS themselves. The aim of our study was to utilize a sodium dodecyl sulfate decellularization procedure in combination with a low concentration of trypsin (0.005%)-ethylenediaminetetraacetic acid (0.002%) process to manufacture DLS from whole mouse livers and recellularized with hepatic stem/progenitors for use in liver tissue engineering and injured liver treatment. Results showed that the DLS generated with all the necessary microstructure and the extracellular components to support seeded hepatic stem/progenitor cell attachment, functional hepatic cell differentiation. Hepatic differentiation from stem/progenitor cells loaded by DLS was more efficient than that of the stem/progenitor cells in the two-dimensional cell culture model. In summary, the method of DLS loaded by hepatic stem/progenitor cells provided by this study was effective in maintaining DLS extracellular matrix to introduce seeded stem/progenitor cell differentiation, hepatic-like tissue formation and functional hepatic protein production in vitro that promoted functional recovery and survival in a mouse model of dimethylnitrosamine-induced liver cirrhosis after auxiliary heterotopic liver transplantation.

Abstract
AIM To investigate the effects of heme oxygenase-1 (HO-1)-modified bone marrow mesenchymal stem cells (BMMSCs) on the microcirculation and energy metabolism of hepatic sinusoids following reduced-size liver transplantation (RLT) in a rat model.
METHODS BMMSCs were isolated and cultured in vitro using an adherent method, and then transduced with HO-1-bearing recombinant adenovirus to construct HO-1/BMMSCs. A rat acute rejection model following 50% RLT was established using a two-cuff technique. Recipients were divided into three groups based on the treatment received: normal saline (NS), BMMSCs and HO-1/BMMSCs. Liver function was examined at six time points. The levels of endothelin-1 (ET-1), endothelial nitric-oxide synthase (eNOS), inducible nitric-oxide synthase (iNOS), nitric oxide (NO), and hyaluronic acid (HA) were detected using an enzyme-linked immunosorbent assay. The portal vein pressure (PVP) was detected by Power Lab ML880. The expressions of ET-1, iNOS, eNOS, and von Willebrand factor (vWF) protein in the transplanted liver were detected using immunohistochemistry and Western blotting. ATPase in the transplanted liver was detected by chemical colorimetry, and the ultrastructural changes were observed under a transmission electron microscope.
RESULTS HO-1/BMMSCs could alleviate the pathological changes and rejection activity index of the transplanted liver, and improve the liver function of rats following 50% RLT, with statistically significant differences compared with those of the NS group and BMMSCs group (P < 0.05). In term of the microcirculation of hepatic sinusoids: The PVP on POD7 decreased significantly in the HO-1/BMMSCs and BMMSCs groups compared with that of the NS group (P < 0.01); HO-1/BMMSCs could inhibit the expressions of ET-1 and iNOS, increase the expressions of eNOS and inhibit amounts of NO production, and maintain the equilibrium of ET-1/NO (P < 0.05); and HO-1/BMMSCs increased the expression of vWF in hepatic sinusoidal endothelial cells (SECs), and promoted the degradation of HA, compared with those of the NS group and BMMSCs group (P < 0.05). In term of the energy metabolism of the transplanted liver, HO-1/BMMSCs repaired the damaged mitochondria, and improved the activity of mitochondrial aspartate aminotransferase (ASTm) and ATPase, compared with the other two groups (P <0.05).
CONCLUSION HO-1/BMMSCs can improve the microcirculation of hepatic sinusoids significantly, and recover the energy metabolism of damaged hepatocytes in rats following RLT, thus protecting the transplanted liver.

Abstract
The aim of this study was to assess the independent association between pre-transplant prescription opioid use and readmission following liver transplantation. We reviewed the medical records of all patients at a single medical center undergoing primary, single-organ, liver transplantation from 2004 to 2014. We assessed factors associated with hospital readmission 30 days and 1 year after hospital discharge using multivariable competing risk regression models. Among 1056 transplant recipients, 49 (4.6%) were prescribed pre-transplant prescription opioids. Readmission occurred in 421 (40%) patients within 30 days and 689 (65%) within 1 year. Patients with pre-transplant opioid use had a significantly higher risk of readmission at 30 days (HR 1.7; 95% CI 1.1-2.5) and a non-significantly elevated risk at 1 year (HR 1.4; 95% CI 1.0-1.9) when controlling for other potential confounders. Although pain was the major reason for readmission in only 12 (3%) patients at 30 days and 33 (6%) patients at 1 year, pre-transplant opioid use was significantly associated with pain-related readmission at both time points. In conclusion, prescription opioid use pre-transplantation was significantly associated with all-cause 30-day readmissions and pain-related readmissions at 30 days and 1 year.

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