Abstract
BACKGROUND Liver transplantation (LT) offers patients with decompensated cirrhosis the best chance at long-term survival. With the rising prevalence of diabetes, further clarity is needed on the impact of receiving a liver allograft from a donor with diabetes on post-LT outcomes. This study aims to evaluate the impact of donor diabetes on clinical outcomes after LT. METHODS This is a retrospective analysis of the United Network for Organ Sharing registry data of LT recipients from January 1, 2000, to December 31, 2021. Outcomes analysis was performed using Cox proportional model for all-cause mortality and graft failure. Confounding was reduced by coarsened exact matching causal inference analysis. RESULTS Of 66 960 donors identified, 7178 (10.7%) had diabetes. Trend analysis revealed a longitudinal increase in the prevalence of donor diabetes ( P < 0.001). Importantly, donor diabetes was associated with increased all-cause mortality (hazard ratio [HR]: 1.13; 95% confidence interval [CI], 1.07-1.19; P < 0.001) and graft failure (HR: 1.16; 95% CI, 1.11-1.22; P < 0.001). Receiving donor organ with diabetes reduced graft survival in patients who received LT for nonalcoholic steatohepatitis cirrhosis (HR: 1.26; 95% CI, 1.13-1.41; P < 0.001) but not other etiologies of cirrhosis. CONCLUSIONS Donor diabetes was associated with worse outcomes post-LT, particularly in patients receiving LT for nonalcoholic steatohepatitis cirrhosis. Future studies are needed to better understand the mechanism underlying this association to develop better risk stratification and clinical practice to improve the outcomes of the transplanted patients.

Abstract
Oral disease is linked with systemic inflammation and various systemic conditions, including chronic liver disease. Liver transplantation (LT) candidates often need dental infection focus eradication, and after LT, there is high risk of many inflammation-related complications. We studied whether pre-LT dental status is associated with the occurrence of post-LT complications. This study included 225 adult LT recipients whose teeth were examined and treated before LT, and 40 adult LT recipients who did not have pre-LT dental data available. Data on post-LT complications were collected from the national liver transplant registry and followed up until the end of July 2020. Worse pre-LT dental status was associated with a higher risk of acute rejection post-LT compared to patients with good dental status. Worse dental status was also associated with higher 1-year-post-LT ALT levels and lower albumin levels. In conclusion, poor pre-LT oral health seems to associate with an increased risk of post-LT acute rejection and with elevated ALT levels and decreased albumin levels, suggesting an effect on post-LT liver health. Therefore, prevention and treatment of oral and dental diseases should be promoted early in the course of liver disease.

Abstract
BACKGROUND & AIMS Autoimmune hepatitis (AIH) is a rare indication for liver transplantation (LT). The aims of this study were to evaluate long-term survival after LT for AIH and prognostic factors, especially the impact of recurrent AIH (rAIH). METHODS A multicentre retrospective nationwide study including all patients aged ≥16 transplanted for AIH in France was conducted. Early deaths and retransplantations (≤6 months) were excluded. RESULTS The study population consisted of 301 patients transplanted from 1987 to 2018. Median age at LT was 43 years (IQR, 29.4-53.8). Median follow-up was 87.0 months (IQR, 43.5-168.0). Seventy-four patients (24.6%) developed rAIH. Graft survival was 91%, 79%, 65% at 1, 10 and 20 years respectively. Patient survival was 94%, 84% and 74% at 1, 10 and 20 years respectively. From multivariate Cox regression, factors significantly associated with poorer patient survival were patient age ≥58 years (HR = 2.9; 95% CI, 1.4-6.2; p = 0.005) and occurrence of an infectious episode within the first year after LT (HR = 2.5; 95% CI, 1.2-5.1; p = 0.018). Risk factors for impaired graft survival were: occurrence of rAIH (HR = 2.7; 95% CI, 1.5-5.0; p = 0.001), chronic rejection (HR = 2.9; 95% CI, 1.4-6.1; p = 0.005), biliary (HR = 2.0; 95% CI, 1.2-3.4; p = 0.009), vascular (HR = 1.8; 95% CI, 1.0-3.1; p = 0.044) and early septic (HR = 2.1; 95% CI, 1.2-3.5; p = 0.006) complications. CONCLUSION Our results confirm that survival after LT for AIH is excellent. Disease recurrence and chronic rejection reduce graft survival. The occurrence of an infectious complication during the first year post-LT identifies at-risk patients for graft loss and death.

Chen TS, Lai YA, Lai YJ, Chien CT. Adipose stem cells preincubated with theanine exert liver regeneration through increase of stem cell paracrine VEGF and suppression of ROS, pyroptosis as well as autophagy markers in liver damage induced by N-nitrosodiethylamine. Life Sci 2022; 308:120969. [PMID: 36116531 DOI: 10.1016/j.lfs.2022.120969] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2022] [Revised: 09/04/2022] [Accepted: 09/12/2022] [Indexed: 12/19/2022]
Abstract
AIMS Liver diseases induce a severe decrease in quality of life. Stem cell based therapy shows therapeutic potential in the treatment of liver injury. Theanine is a unique amino acid found in green tea and could confer beneficial effects on cell protection. This study investigates if protective effect on the liver by stem cells preincubated with theanine is better than that from stem cells without preincubated theanine. METHODS We transplanted theanine preincubated adipose-derived stem cells (ADSC) to male Wistar rats with liver dysfunction induced by N-nitrosodiethylamine. The viability, migration and antioxidant capabilities were performed in the ADSC pre-incubated with theanine. Hepatic functional, structural and molecular assays were determined in the animals with or without theanine preincubated ADSC. KEY FINDINGS Cell model revealed that ADSC preincubated with green tea theanine (T-ADSC) increased cell capabilities including viability, migration and paracrine secretion. In vivo results indicated that several pathological conditions were observed in rats with liver injury induced by DEN including structural changes and expression of pyroptosis as well as autophagy markers. The above pathological conditions were improved when the rats received both ADSC and T-ADSC treatment. Furthermore, T-ADSC showed better therapeutic effect on rats with liver injury than ADSC due to significant suppression of pyroptosis markers caspase-1 and IL-1β as well as autophagy marker LC3-II accompanied with intensive paracrine VEGF from T-ADSC. SIGNIFICANCE Increased paracrine VEGF secretion from T-ADSC plays a crucial role in liver regeneration. A future clinical study may be designed for further verification of these experimental in vivo findings.

Abstract
BACKGROUND Intraoperative autologous transfusion (IAT) of salvaged blood is a common method of resuscitation during liver transplantation (LT), however concern for recurrence in recipients with hepatocellular carcinoma (HCC) has limited widespread adoption. METHODS A review of patients undergoing LT for HCC between 2008 and 2018 was performed. Clinicopathologic and intraoperative characteristics associated with inferior recurrence-free (RFS) and overall survival (OS) were identified using Kaplan-Meier analysis and uni-/multi-variable Cox proportional hazards modeling. Propensity matching was utilized to derive clinicopathologically similar groups for subgroup analysis. RESULTS One-hundred-eighty-six patients were identified with a median follow up of 65 months. Transplant recipients receiving IAT (n = 131, 70%) also had higher allogenic transfusions (median 5 versus 0 units, P < 0.001). There were 14 recurrences and 46 deaths, yielding an estimated 10-year RFS and OS of 89% and 67%, respectively. IAT was not associated with RFS (HR 0.89/liter, P = 0.60), or OS (HR 0.98/liter, P = 0.83) pre-matching, or with RFS (HR 0.97/liter, P = 0.92) or OS (HR 1.04/liter, P = 0.77) in the matched cohort (n = 49 per group). CONCLUSION IAT during LT for HCC is not associated with adverse oncologic outcomes. Use of IAT should be encouraged to minimize the volume of allogenic transfusion in patients undergoing LT for HCC.

Abstract
BACKGROUND Takotsubo cardiomyopathy (TCM), or stress-induced cardiomyopathy, is associated with adverse prognosis. Limited data suggest that TCM occurring in orthotopic liver transplant (OLT) recipients is associated with elevated peri-operative risk.
AIM To characterize the predictors of TCM in OLT recipients, using a large, multi-center pooled electronic health database.
METHODS A multi-institutional database (Explorys Inc, Cleveland, OH, USA), an aggregate of de-identified electronic health record data from 26 United States healthcare systems was surveyed. A cohort of patients with a Systematized Nomenclature of Medicine-Clinical Terms of “liver transplant” between 09/2015 and 09/2020 was identified. Subsequently, individuals who developed a new diagnosis of TCM following OLT were identified. Furthermore, the risk associations with TCM among this patient population were characterized using linear regression.
RESULTS Between 09/2015 and 09/2020, of 37718540 patients in the database, 38740 (0.10%) had a history of OLT (60.6% had an age between 18-65 years, 58.1% female). A new diagnosis of TCM was identified in 0.3% of OLT recipients (45.5% had an age between 18-65 years, 72.7% female), compared to 0.04% in non-OLT patients [odds ratio (OR): 7.98, 95% confidence intervals: 6.62-9.63, (P < 0.0001)]. OLT recipients who developed TCM, compared to those who did not, were more likely to be greater than 65 years of age, Caucasian, and female (P < 0.05). There was also a significant association with cardiac arrhythmias, especially ventricular arrhythmias (P < 0.0001).
CONCLUSION TCM was significantly more likely to occur in LT recipients vs non-recipients. Older age, Caucasian ethnicity, female gender, and presence of arrhythmias were significantly associated with TCM in LT recipients.

Abstract
BACKGROUND In primary hyperoxaluria Type 1 (PH1), endogenous oxalate overproduction significantly elevates urinary oxalate excretion, resulting in recurrent urolithiasis and/or progressive nephrocalcinosis and often early end-stage renal disease (ESRD). In ESRD, dialysis cannot sufficiently remove oxalate; plasma oxalate (Pox) increases markedly, inducing systemic oxalate deposition (oxalosis) and often death. Interventions to reduce Pox in PH1 subjects with ESRD could have significant clinical impact. This ongoing Phase II, open-label trial aimed to evaluate whether long-term Oxabact™ (Oxalobacter formigenes, OC5, OxThera Intellectual Property AB, Sweden) lowers Pox in PH1 ESRD subjects, ameliorating clinical outcome. METHODS PH1 ESRD subjects on stable dialysis regimens were examined. Subjects were administered one OC5 capsule twice daily for up to 36 months or until transplantation. Total Pox values, cardiac function and safety were evaluated. Free Pox was evaluated in a comparative non-treated PH1 dialysis group using retrospective chart reviews and analyses. RESULTS Twelve subjects enrolled in an initial 6-week treatment phase. Following a washout of up to 4 weeks, eight subjects entered a continuation study; outcomes after 24 months of treatment are presented. After 24 months, all subjects had reduced or non-elevated Pox compared with baseline. Cardiac function improved, then stabilized. No treatment-related serious adverse events were reported. CONCLUSIONS Compared with an untreated natural control cohort, 24 months OC5 administration was beneficial to PH1 ESRD subjects by substantially decreasing Pox concentrations, and improving or stabilizing cardiac function and clinical status, without increasing dialysis frequency. OC5 was safe and well-tolerated.

We hypothesize that long-term CNI therapy affects the neuroimmune system, thereby, increasing the risk of neurodegeneration. Here, we measured the impact of CNI therapy on plasma levels of brain- and T cell-derived cytokines in a cohort of patients after liver transplantation (LT). METHODS Levels of T cell-mediated cytokines (e.g. Interferon-γ (IFN-γ)) and brain-derived cytokines (e.g. brain derived neurotrophic factor (BDNF), platelet derived growth factor (PDGF)) were measured by multiplex assays in plasma of 82 patients about 10 years after LT (17 with CNI free, 35 with CNI low dose, 30 with standard dose CNI immunosuppression) and 33 healthy controls. Data were related to psychometric test results and parameters of cerebral magnetic resonance imaging. RESULTS IFN-γ levels were significantly higher in the CNI free LT patient group (p=0.027) compared to healthy controls. BDNF levels were significantly lower in LT patients treated with CNI (CNI low: p<0.001; CNI standard: p=0.016) compared to controls. PDGF levels were significantly lower in the CNI low dose group (p=0.004) and for PDGF-AB/BB also in the CNI standard dose group (p=0.029) compared to controls. BDNF and PDGF negatively correlated with cognitive function and brain volume (p<0.05) in the CNI low dose group. CONCLUSION Our results imply that long-term treatment with CNI suppresses BDNF and PDGF expression, both crucial for neuronal signaling, cell survival and synaptic plasticity and thereby may lead to cognitive dysfunction and neurodegeneration.

Abstract
Background Systemic inflammatory response syndrome (SIRS) is common in severe fulminant hepatic failure (FHF) and has a high mortality rate (20–50%) due to irreversible cerebral edema or sepsis. Stem cell-based treatment has emerged as a promising alternative therapeutic strategy to prolong the survival of patients suffering from FHF via the inhibition of SIRS due to their immunomodulatory effects. Methods 3D spheroids of adipose-derived mesenchymal stem cells (3D-ADSC) were prepared by the hanging drop method. The efficacy of the 3D-ADSC to rescue FHF was evaluated in a d-galactosamine/lipopolysaccharide (GalN/LPS)-induced mouse model of FHF via intraportal transplantation of the spheroids. Results Intraportally delivered 3D-ADSC better engrafted and localized into the damaged livers compared to 2D-cultured adipose-derived mesenchymal stem cells (2D-ADSC). Transplantation of 3D-ADSC rescued 50% of mice from FHF-induced lethality, whereas only 20% of mice survived when 2D-ADSC were transplanted. The improved transplantation outcomes correlated with the enhanced immunomodulatory effect of 3D-ADSC in the liver microenvironment. Conclusion The study shows that the transplantation of optimized 3D-ADSC can efficiently ameliorate GalN/LPS-induced FHF due to improved viability, resistance to exogenous ROS, and enhanced immunomodulatory effects of 3D-ADSC.

Abstract
PURPOSE To investigate cerebral microstructural alterations in patients treated with calcineurin inhibitors (CNI) after orthotopic liver transplantation (OLT) using quantitative magnetic resonance imaging (qMRI) and a cross-sectional study design. METHODS Cerebral qMRI was performed in 85 patients in a median 10 years after OLT compared to 31 healthy controls. Patients were treated with different dosages of CNI or with a CNI-free immunosuppression (CNI-free: n = 19; CNI-low: n = 36; CNI-standard: n = 30). T2-, T2*- and T2'- relaxation times, as well as apparent diffusion coefficient (ADC) and fractional anisotropy (FA) were measured in brain gray and white matter by using the regions of interest method. RESULTS In comparison to controls, patients revealed significantly increased T2, T2*, T2', ADC and reduced FA, predominantly in the frontal white matter, indicating microstructural brain alterations represented by increased free water (increased T2), reduced neuronal metabolism (increased T2') and a lower degree of spatial organization of the nervous fibers (reduced FA). CNI-low and CNI-free patients showed more alterations than CNI-standard patients. Analysis of their history revealed impairment of kidney function while under standard CNI dose suggesting that these patients may be more vulnerable to toxic CNI side-effects. CONCLUSION Our findings suggest that the individual sensitivity to toxic side effects should be considered when choosing an appropriate immunosuppressive regimen in patients after liver transplantation.

Abstract
BACKGROUND Calcineurin inhibitor (CNI) neurotoxicity after liver transplantation might be due to impairment of the cerebral metabolism. AIMS To investigate CNI-related alterations of brain metabolite distributions and associations between cognitive function and brain metabolism in patients with long-term CNI treatment after liver transplantation. METHODS Eighty-two patients (19 CNI free, 34 CNI low-dose and 29 standard-dose CNI immunosuppression) 10 years after liver transplantation and 32 adjusted healthy controls underwent nonlocalised brain phosphorus magnetic resonance spectroscopy (MRS) and single voxel proton MRS in the parietal white matter to estimate brain metabolite contents. The MRS results were correlated with psychometric data assessing cognitive function. RESULTS Phosphorus metabolite concentrations with the exception of phosphocreatine (PCr) were reduced in patients compared to controls. Particularly, patients with low-dose CNI therapy showed a significant decrease in adenosine triphosphate (0.209 ± 0.012 vs 0.222 ± 0.010; P < 0.001) and a significant increase in PCr (0.344 ± 0.026 vs 0.321 ± 0.017; P < 0.001) compared to controls. Myo-Inositol in the CNI free group (2.719 ± 0.549 institutional unit [iu]) was significantly lower compared to controls (3.181 ± 0.425 iu; P = 0.02), patients on low-dose (3.130 ± 0.513 iu; P < 0.05) and standard-dose CNI therapy (3.207 ± 0.632 iu; P < 0.02). Glutamate and glutamine levels correlated negatively with cognitive function (Repeatable Battery for the Assessment of Neuropsychological Status Total Scale: R = -0.362, P = 0.029). CONCLUSION Long-term CNI therapy after liver transplantation might be associated with alterations of brain metabolites.

Abstract
The aim of the present study was to investigate the characteristics and progression of intestinal injury at the anhepatic phase in portal hypertensive rats. A total of 120 healthy male Wistar rats were purchased, with 15 rats in the normal control group and 105 rats were assigned to establish a prehepatic portal hypertension model. The 105 model rats were further divided into seven treatment groups following ischemia-reperfusion. Meanwhile, portal vein pressure, the area of lower esophageal mucosal vein, endotoxin levels in portal vein blood and the level of malondialdehyde (MDA) and superoxide dismutase (SOD) were measured. Morphology changes of the intestine were observed using optical microscopy and transmission electron microscopy. A portal hypertension rat model was successfully established. Furthermore, endotoxin, MDA and SOD level reached a peak at 12-24 h following reperfusion and then decreased gradually to normal levels at 1 week following reperfusion. However, cytological damage did not recover to preoperative level within 1 week. These findings suggest that intestinal injury was most severe within 12-24 h following ischemia-reperfusion and most indicators recovered to almost normal levels. Therefore, further study on the intestinal mucosal damage is required, with the aim to reduce the production of intestinal endotoxin.

Abstract
OBJECTIVE To investigate prognostic factors of more than 10 years of survival for liver cancer patients after liver transplantation. METHODS From May 2000 to May 2007, a total of 134 liver cancer patients who underwent liver transplantation in the Department of Hepatobiliary Surgery, Peking University People's Hospital, were continuously and retrospectively enrolled. The patients included 120 males and 14 females. There were 124 cases (92.5%) of primary hepatocellular carcinoma, 9 cases (6.7%) of cholangiocarcinoma, and 1 case of mixed hepatocellular carcinoma and cholangiocarcinoma. Patients with perioperative death were excluded. Follow-up was performed until May 31st, 2017 or the time of death. According to the data on postoperative survival time, patients were divided into a < 10 years group (81 cases) and a ≥ 10 years group (53 cases). Patients' clinical data were recorded and analyzed, including alpha-fetoprotein (AFP) level (≥ 400 µg/L or < 400 µg/L), number of tumor lesions (< 3 or ≥ 3), tumor size (≤ 5 cm or > 5 cm), vascular tumor thrombus (large blood vessel or non-large blood vessel), and histological differentiation degree. The Kaplan-Meier method was used to calculate survival rates. The log-rank method was used to compare the differences between survival curves. The Cox proportional hazards regression model was used to perform multivariate analyses of possibly influential factors. RESULTS (1) Follow-up was conducted with all 134 liver cancer patients after liver transplantation. The follow-up periods were 1-201 months, with a median of 18 (8.75, 132.5) months. The Kaplan-Meier survival analysis results showed that the 1-year, 3-year, 5-year, and 10-year cumulative survival rates were 70.3%, 48.6%, 46.8%, and 46.8%, respectively. (2) The differences in the age of patients, the incidence rate of AFP ≥ 400 µg/L, tumor histological differentiation, vascular tumor thrombi, tumor lesion size, and number of tumor lesions between two groups were all statistically significant (all P < 0.01). (3) The cumulative survival rates were different in AFP (log-rank χ2 = 13.428), histopathologic differentiation (log-rank χ2 = 33.592), large blood vessel tumor thrombi (log-rank χ2 = 36.470), tumor lesion size (log-rank χ2 = 39.835), and number of tumor lesions (log-rank χ2 = 47.016), and there were statistically significant differences between groups (all P < 0.01). (4) Multivariate Cox proportional hazards regression analyses showed that ≥ 3 tumor lesions [hazard ratio (HR) = 2.879, 95% confidence interval (CI) 1.566-5.422], tumor lesion size > 5 cm (HR = 2.682, 95% CI 1.382-5.366), large blood vessel tumor thrombi (HR = 1.831, 95% CI 1.010-3.341), and poor histological differentiation (HR = 2.150, 95% CI 1.372-3.394), were risk factors affecting the 10-year survival of liver cancer patients after liver transplantation (all P < 0.05). CONCLUSION Tumor size, tumor number, large blood vessel tumor thrombi, and low tumor differentiation were all found to be independent risk factors affecting the 10-year survival rate after liver transplantation in liver cancer patients.

Abstract
The number of individuals aged 65 or older is projected to increase globally from 524 million in 2010 to nearly 1. 5 billion in 2050. Aged individuals are particularly at risk for developing chronic illness, while being less able to regenerate healthy tissue and tolerate whole organ transplantation procedures. In the liver, these age-related diseases include non-alcoholic fatty liver disease, alcoholic liver disease, hepatitis, fibrosis, and cirrhosis. Hepatic macrophages, a population comprised of both Kupffer cells and infiltrating monocyte derived macrophages, are implicated in several chronic liver diseases and also play important roles in the homeostatic functions of the liver. The effects of aging on hepatic macrophage population dynamics, polarization, and function are not well understood. Studies performed on macrophages derived from other aged sources, such as the bone marrow, peritoneal cavity, lungs, and brain, demonstrate general reductions in autophagy and phagocytosis, dysfunction in cytokine signaling, and altered morphology and distribution, likely mediated by epigenetic changes and mitochondrial defects, that may be applicable to hepatic macrophages. This review highlights recent findings in macrophage developmental biology and function, particularly in the liver, and discusses the role of macrophages in various age-related liver diseases. A better understanding of the biology of aging that influences hepatic macrophages and thus the progression of chronic liver disease will be crucial in order to develop new interventions and treatments for liver disease in aging populations.

Abstract
OBJECTIVES We investigated late mortality causes and risk factors in patients who were undergoing deceased-donor liver transplant. MATERIALS AND METHODS Patients who had deceased-donor liver transplant from February 1997 to June 2014 in the hepatopancreaticobiliary surgery and liver transplant unit at Dokuz Eylul University Hospital were analyzed. Inclusion criteria were patients over 18 years of age and who survived more than 1 year after liver transplant. Causes of mortality and related risk factors after the first year were analyzed. RESULTS Of the 157 included patients, 102 patients (72%) received transplant procedures for hepatitis B and C secondary to chronic liver disease. Mean follow-up was 89.85 months (range, 14.4-240 months). Of 157 patients, 20 patients (12.7%) died: 12 patients (60%) died during posttransplant years 2-5 and 8 patients (40%) died after 5 years. Causes of death included malignancy in 8 patients (40%), recurrent hepatitis C infection in 3 patients (15%), infection in 3 patients (15%), coronary artery disease in 2 patients (10%), graft rejection in 2 patients (10%), and biliary complications in 2 patients (10%). Univariate analyses showed that long-term survival was significantly lower in patients older than 50 years (P = .001), when there was presence of hepatocellular carcinoma (P = .011), and when donor age was higher than 38 years (P = .045). Multivariate analyses identified recipient age (P = .007) and presence of hepatocellular carcinoma (P = 0.033) as factors that reduced long-term survival. CONCLUSIONS The main causes of late mortality in liver transplant are malignancy, recurrence of hepatitis C, infection, coronary artery disease, graft rejection, and biliary complications. Advanced age and hepatocellular carcinoma are independent risk factors that increase late mortality.

Abstract
Calcineurin inhibitors (CNIs) frequently induce neurological complications early after orthotopic liver transplantation (OLT). We hypothesize that longterm CNI therapy after OLT causes dose-dependent cognitive dysfunction and alteration of brain structure. In this study, 85 OLT patients (20 with CNI-free, 35 with CNI low-dose, and 30 with standard-dose CNI immunosuppression) underwent psychometric testing and cerebral magnetic resonance imaging approximately 10 years after OLT to assess brain function and structural brain alterations. A total of 33 healthy patients adjusted for age, sex, and education served as controls. Patients receiving CNI showed a significantly worse visuospatial/constructional ability compared with controls (P ≤ 0.04). Furthermore, patients on low-dose CNI therapy had an overall impaired cognitive function compared with controls (P = 0.01). The tacrolimus total dose and mean trough level were negatively correlated to cognitive function. CNI doses had been adjusted in 91% of the patients in the low-dose and CNI-free groups in the past due to CNI-induced kidney damage. Patients treated with CNI showed significantly more white matter hyperintensities (WMH) than patients on CNI-free immunosuppression and controls (P < 0.05). Both the mean cyclosporine A and tacrolimus trough levels correlated significantly with WMH. In conclusion, longterm CNI therapy carries a risk of cognitive dysfunction especially in patients who already showed nephrotoxic side effects indicating an increased susceptibility of these patients against toxic CNI effects. This subgroup of patients might benefit from a change to CNI-free immunosuppression. Liver Transplantation 24 56-66 2018 AASLD.

Abstract
BACKGROUND Patients with primary sclerosing cholangitis (PSC) may be at higher risk of malignancy after liver transplantation (LT) compared to other LT recipients. We aimed to determine the cumulative incidence of/risk factors for long-term cancer-related mortality in patients with PSC after LT. METHODS All adult patients underwent LT for PSC without cholangiocarcinoma from 1984 to 2012, with follow-up through June 2015. We estimated cumulative incidence, risk factors, and mortality from de novo malignancies after LT. RESULTS Two hundred ninety-three patients were identified (mean [SD] age, 47 [12] years; 63.3% males; 2.4% smoking at LT). Over a median of 11.5 years (range, 6.4-18.6 years), 64 patients (21.8%) developed 73 nonskin cancers, including 46 solid-organ cancers (renal, 11; colorectal, 11; prostate, 7; breast, 5; pancreas, 5; ovarian/endometrial/vulvar cancers, 3; and de novo cholangiocarcinoma, 4). Twenty-two patients developed hematologic malignancies (posttransplant lymphoproliferative diseases, 18; Hodgkin disease, 2; and myelodysplastic syndrome, 2). Five patients developed melanoma. The 1-, 5-, 10-, and 20-year cumulative incidences of cancer were 2.1%, 8.6%, 18.7%, and 27%, respectively. Mortality of patients with PSC who developed cancer was higher than that of patients with PSC without cancer (hazard ratio, 2.2; P < 0.01). On multivariate analysis, recipient's age and elevated pre-LT international normalized ratio were associated with increased risk of de novo (nonskin) malignancy. CONCLUSION The 10-year cumulative risk of cancer after LT for advanced-stage PSC was 18.7%, with posttransplant lymphoproliferative diseases, colorectal cancer, and renal cell cancer being the most common. Post-LT de novo nonskin cancer decreased overall posttransplant survival. Only recipient's age and elevated international normalized ratio at LT were associated with increased nonskin cancer risk.

Abstract
Background and Aims. Gastrointestinal surveillance is a requirement prior to liver transplantation (LT), but small intestine examination is not generally undertaken. The aim of the present study was to evaluate the safety and efficacy of capsule endoscopy (CE) for patients with end-stage liver disease. Methods. 31 patients who needed LT were enrolled, and 139 patients who underwent CE over the same period of time acted as controls. Results. Frequency of successful achievement of evaluation of the full length of the small bowel, the mean gastric transit time, and the mean small bowel transit time were not significantly different between the two groups. Abnormalities in the small bowel were found in 26 patients. Comparative analysis revealed that history of EV rupture, history of EV treatment, red color sign of EV, and presence of PHG or HCC were significantly associated with patients with >2 two such findings (high score group). Conclusions. Small bowel examination by CE in patients before liver transplantation could be performed safely and is justified by the high rate of abnormal lesions detected particularly in patients with history of EV therapy or bleeding, red color sign, and presence of PHG or HCC. This study was registered in the UMIN Clinical Trial Registry (UMIN 000008672).

Abstract
BACKGROUND As more patients achieve long-term survival, it has become important to understand mortality in liver transplantation (LT) recipients. METHODS We conducted retrospective reviews of long-term outcome in two adult LT cohorts: 85 031 in the United Network for Organ Sharing (UNOS) database and 1458 transplanted at the University of Wisconsin (UW). RESULTS During median follow-up of 3.2 years (UNOS) and 6.6 years (UW), 35.1% of UNOS patients and 44.2% of UW patients died; 43.1% of all UNOS deaths occurred in year 1 compared to 25.1% in the UW cohort. Deaths due to infection (other than viral hepatitis) or cardiovascular (CV) causes were most frequent in year 1 in both cohorts and then persisted at lower rates. In contrast, death from malignancy increased after year 1 to peak in years 1-5. Deaths due to rejection, hepatitis, or graft failure were infrequent. In the UW cohort, de novo malignancy was more common than recurrent tumor and correlated with smoking history. CONCLUSIONS A coordinated holistic approach that focuses on limiting immunosuppression, infection, risky behaviors, and CV risks, while screening for cancer, is needed to extend the healthy lives of LT recipients.

Abstract
Liver transplantation has been established as a curative therapy for acute and chronic liver failure, as well as liver-based inherited metabolic diseases. Because of the complexity of organ transplantation and the worldwide shortage of donor organs, hepatocyte transplantation is being developed as a bridging therapy until donor organs become available, or for amelioration of inherited liver-based diseases. The Gunn rat is a molecular and metabolic model of Crigler-Najjar syndrome type 1, which is characterized by lifelong unconjugated hyperbilirubinemia due to the lack of uridinediphosphoglucuronate glucuronosyltransferase-1 (UGT1A1)-mediated bilirubin glucuronidation. Gunn rats are convenient for evaluating the effect of hepatocyte transplantation or gene therapy, because the extent of UGT1A1 replacement can be assessed by serial determination of serum bilirubin levels, and excretion of bilirubin glucuronides in bile provide definitive evidence of the function of the transplanted hepatocytes or the effect of gene therapy. The core techniques involved in hepatocyte transplantation in Gunn rats are discussed in this chapter.

Abstract
CONTEXT The discrepancy between donor supply and organ demand increased the possibility of gender and race mismatch between the donors and recipients. However, the findings of their impact on graft and patient survival are outdated and mixed. OBJECTIVE To estimate the effects of gender and race mismatch on graft survival and patient survival among adult patients (18 years and older) with end-stage liver disease. DESIGN A total of 38 768 patients undergoing liver transplant between 2002 and 2011 were identified from United Network for Organ Sharing database. Kaplan-Meier curves, log-rank tests, and Cox proportional hazard regressions with backward elimination adopting a marginal approach with a working independence assumption and stratification on recipient hepatitis C virus status were used. MAIN OUTCOME MEASURES Posttransplantation graft survival and patient survival. RESULTS Both gender mismatch (hazard ratio [HR]: 1.14, 95% confidence interval [CI]: 1.09-1.12) and race mismatch (HR 1.08, 95%C: 1.04-1.12) had significantly adverse effects on graft survival and patient survival after controlling for other factors, especially among hepatitis C-positive female recipients with male donors (HR 1.13, 95%CI 1.03-1.24), black recipients with white donors (1.39, 1.29-1.49) or Hispanic donors (HR 1.48, 95%CI 1.27-1.72), and these effects were even worse among hepatitis C-positive recipients. CONCLUSION Gender and race mismatch between donors and recipients adversely affected graft survival and patient survival among adult patients with end-stage liver disease, both independently and after the adjustment for other factors. Future research is recommended to explore other factors such as new model for end-stage liver disease sharing policy change and disparities in access to waiting-list or transplantation.

Abstract
SOFT and BAR scores utilize recipient, donor, and graft factors to predict the 3-month survival after LT in adults (≥18 years). Recently, Pedi-SOFT score was developed to predict 3-month survival after LT in young children (≤12 years). These scoring systems have not been studied in adolescent patients (13-17 years). We evaluated the accuracy of these scoring systems in predicting the 3-month post-LT survival in adolescents through a retrospective analysis of data from UNOS of patients aged 13-17 years who received LT between 03/01/2002 and 12/31/2012. Recipients of combined organ transplants, donation after cardiac death, or living donor graft were excluded. A total of 711 adolescent LT recipients were included with a mean age of 15.2±1.4 years. A total of 100 patients died post-LT including 33 within 3 months. SOFT, BAR, and Pedi-SOFT scores were all found to be good predictors of 3-month post-transplant survival outcome with areas under the ROC curve of 0.81, 0.80, and 0.81, respectively. All three scores provided good accuracy for predicting 3-month survival post-LT in adolescents and may help clinical decision making to optimize survival rate and organ utilization.

Abstract
INTRODUCTION Long-term exposure to calcineurin inhibitor-based immunosuppressant (IS) therapy in liver transplant (LT) recipients is associated with renal complications. In the randomized trial H2304, everolimus + reduced-dose tacrolimus (EVR + rTAC) demonstrated equivalent efficacy and superior renal function compared to standard-dose tacrolimus. METHODS To evaluate the cost-effectiveness of EVR + rTAC vs TAC, in de novo LT patients, a Markov model simulating both liver and kidney function was developed and estimated the long-term outcomes of IS following LT. The analysis used the Italian healthcare payer perspective. RESULTS Patients treated with EVR + rTAC gained on average 1.92 years and 1.62 quality-adjusted life years (QALYs). The incremental cost-effectiveness ratios (ICER) were €35,851 and €42,567 for LY gained and QALY gained, respectively. For the hepatitis-c sub-population, the ICERs decreased to €22,519 and €30,658, respectively. CONCLUSION EVR + rTAC improves survival and quality-of-life and is a cost-effective alternative to calcineurin-inhibitor monotherapy for patients requiring LT.

Abstract
Sarcopenia, a loss of muscle mass, is being increasingly recognized to have a deleterious effect on outcomes in patients with chronic liver disease. Factors related to diet and the inflammatory nature of chronic liver disease contribute to the occurrence of sarcopenia in these patients. Sarcopenia adversely influences quality of life, performance, morbidity, success of transplantation, and even mortality. Specific deficiencies in macronutrients (protein, polyunsaturated fatty acids) and micronutrients (vitamins C, D, and E, carotenoids, and selenium) have been linked to sarcopenia. Lessons learned from nutritional therapy in geriatric patient populations may provide strategies to manage sarcopenia in patients with liver disease. Combining diet modification and nutrient supplementation with an organized program of exercise may help ameliorate or even reverse the effects of sarcopenia on an already complex disease process.

Early Predictors of Long-term Outcomes of HCV-negative Liver Transplant Recipients Having Survived the First Postoperative Year. Transplantation 2016; 100:382-90.

Abstract
BACKGROUND The non-improvement in >1-year post-liver transplant (LT) survival and diminishing importance of hepatitis C (HCV) with modern antivirals justify identification of early factors predictive of long-term outcome post-LT in HCV-negative recipients. METHODS This nationwide study included all 631 HCV-negative adult patients transplanted in Finland 1982-2013 with at least 1-year graft survival (6311 person-year follow-up). We tested 37 variables, including immunosuppression, for their association with >1-year combined graft loss/mortality, late rejection, cancer, or infections. RESULTS Significant multivariate predictors of graft loss/mortality were male gender (HR 2.40, P = 0.001), pretransplant hepatocellular (HR 2.92, P = 0.001) or biliary cancer (HR 12.7, P < 0.001), glomerular filtration rate (HR 0.89, P = 0.002), hypertension (HR 0.44, P < 0.001), early posttransplant infections (HR 1.52-1.67, P = 0.007-0.03), and alkaline phosphatase (ALP) (HR 1.05, P < 0.001). Elevated ALP at 1 year, affecting 30% of patients, predicted both graft loss and rejection, independent of immunologic stability, etiology, and immunosuppression type. Area under the curve of ALP in predicting graft loss from rejection was 0.81 (95% CI 0.71-0.90) and 0.85 (95% CI 0.72-0.98, P = 0.001) among patients under 50. Among immunologically stable patients who underwent transplantation after 2000, antimetabolite use at 1 year was associated with improved survival (P = 0.04), specifically in the subgroup with native-liver hepatocellular or biliary cancer (P = 0.02). CONCLUSIONS Easily measurable, widely available, and noninvasive factors known at 1 year post-LT can help stratify patients according to their long-term risk of death or graft loss, and thus facilitate a personalization of long-term follow-up. ALP deserves routine monitoring, and the cause for an elevated ALP should be sought.

Abstract
Hepatocellular carcinoma (HCC) is the most common complication of HCV infection leading to liver transplantation. We evaluated the impact of aetiology of liver disease on patient and graft survival following liver transplantation for HCC. From the Scientific Registry of Transplant Recipients (2002-2011), all adults who underwent liver transplantation for HCC were retrospectively included. Aetiology of liver disease was grouped into HCV, HBV, HCV-HBV co-infection and nonviral liver disease. Of 8,733 liver transplant recipients with HCC, 5507 had HCV, 631 had HBV, 163 were co-infected, and 2432 had nonviral causes of liver disease. In follow-up (48 ± 32 months), 8.2% had graft failure and 29.5% died. The mean rates of graft failure were 9.5%, 4.7%, 6.1% and 6.4% in HCV, HBV, HCV-HBV co-infection and nonviral liver disease, respectively (P < 0.0001). Post-transplant mortality rate in patients with HBV was 20.2%, HCV 31.0%, HCV-HBV 28.5% and nonviral 28.5% (P < 0.0001). This difference was significant starting one year post-transplant and became even more prominent later in follow-up. Five-year post-transplant survival was 64.7% in HCV, 77.7% in HBV, 71.0% in HCV-HBV and 69.1% in nonviral HCC (P < 0.0001). A diagnosis of HCV in patients with HCC was also independently associated with an increased risk of both graft failure (adjusted hazard ratio = 1.84 (1.46-2.33), P < 0.0001) and mortality (1.35 (1.21-1.50), P < 0.0001) in multivariate analysis. Patients with HCV-related HCC are at higher risk of adverse post-transplant outcomes. These patients should be considered for preemptive interferon-free antiviral therapy prior to or immediately following liver transplantation.

Abstract
CONTEXT Ubiquitous findings regarding the quality of life (QOL) of transplant patients have yet to be explained from a theoretical perspective. OBJECTIVE To investigate transplant patients' QOL by using the conceptual framework of crisis theory. DESIGN Cross-sectional study to explore differences in transplant patients' experiences of stress, coping, and QOL. Regression analysis was used to test crisis theory in relation to QOL, stress, and coping. PARTICIPANTS A total of 226 participants representing transplant candidates, transplant recipients, and nontransplant individuals participated via survey-based data collection. RESULTS Results showed that transplant candidates experience lower QOL than transplant recipients and nontransplant individuals. No significant differences were detected regarding stress levels or coping styles. Stress made a significant contribution to patients' QOL. CONCLUSIONS Current findings suggest important QOL benefits of organ transplant. Using a theoretical model is an effective way to investigate the QOL of people experiencing chronic illness such as end-stage organ failure. Further investigation is required to reach a conclusive understanding of the complex interaction between transplant patients' QOL, stress, and coping.

Dexmedetomidine Inhibits TLR4/NF-κB Activation and Reduces Acute Kidney Injury after Orthotopic Autologous Liver Transplantation in Rats. Sci Rep 2015; 5:16849.

Abstract
Patients who undergo orthotopic liver transplantation often sustain acute kidney injury(AKI). The toll-like receptor 4(TLR4)/Nuclear factor-кB(NF-кB) pathway plays a role in AKI. Dexmedetomidine(Dex) has been shown to attenuate AKI. The current study aimed to determine whether liver transplantation-induced AKI is associated with inflammatory response, and to assess the effects of dexmedetomidine pretreatment on kidneys in rats following orthotopic autologous liver transplantation(OALT). Seventy-seven adult male rats were randomized into 11 groups. Kidney tissue histopathology and levels of blood urea nitrogen(BUN) and serum creatinine(SCr) were evaluated. Levels of TLR4, NF-κB, tumor necrosis factor-α, and interleukin-1β levels were measured in kidney tissues. OALT resulted in significant kidney functional impairment and tissue injury. Pre-treatment with dexmedetomidine decreased BUN and SCr levels and reduced kidney pathological injury, TLR4 expression, translocation of NF-κB, and cytokine production. The effects of dexmedetomidine were reversed by pre-treatment with atipamezole and BRL44408, but not ARC239. These results were confirmed by using α2A-adrenergic receptor siRNA which reversed the protective effect of dexmedetomidine on attenuating NRK-52E cells injury induced by hypoxia reoxygenation. In conclusion, Dexmedetomidine-pretreatment attenuates OALT-induced AKI in rats which may be contributable to its inhibition of TLR4/MyD88/NF-κB pathway activation. The renoprotective effects are related to α2A-adrenergic receptor subtypes.

The role of liver transplantation or resection for patients with early hepatocellular carcinoma. Tumour Biol 2015; 37:4193-201. [PMID: 26490991 DOI: 10.1007/s13277-015-4243-z] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2015] [Accepted: 10/12/2015] [Indexed: 12/14/2022] Open
Abstract
Liver resection (LR) and liver transplantation (LT) are curative treatments for early hepatocellular carcinoma (HCC), although their performance remains debated. We compared the survival of patients with HCC conforming to the Milan criteria (MC) after LT and LR and analyzed factors affecting clinical outcomes. Between January 2006 and January 2013, 65 and 184 patients received LT and LR for HCCs fulfilling the MC, respectively. Overall survival (OS) and disease-free survival (DFS) rates were compared between the two groups. To investigate effects of liver function and living donor liver transplantation (LDLT) on survival, two subgroup analyses were performed and associations with OS and DFS were examined. We found that OS rates were higher after LT than after LR since 3 years postoperatively. DFS rates were significantly better after LT than after LR. Performance of LR, vascular invasion, and tumor multiplicity were associated with poor DFS, and factors affecting OS included the presence of vascular invasions, liver cirrhosis, and tumor multiplicity. In conclusion, despite of the effects of tumor characteristics on clinical outcomes, LT, including LDLT, should be considered the treatment of choice for patients with HCCs who met the MC. The role of LR is to identify poor prognostic factors through pathological examination.

PLoS One 2015; 10:e0134874. [PMID: 26274497 PMCID: PMC4537224 DOI: 10.1371/journal.pone.0134874] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2015] [Accepted: 07/14/2015] [Indexed: 12/11/2022] Open
Abstract
BACKGROUND Liver transplantation has received increased attention in the medical field since the 1980s following the introduction of new immunosuppressants and improved surgical techniques. Currently, transplantation is the treatment of choice for patients with end-stage liver disease, and it has been expanded for other indications. Liver transplantation outcomes depend on donor factors, operating conditions, and the disease stage of the recipient. A retrospective cohort was studied to identify mortality and graft failure rates and their associated factors. All adult liver transplants performed in the state of São Paulo, Brazil, between 2006 and 2012 were studied. METHODS AND FINDINGS A hierarchical Poisson multiple regression model was used to analyze factors related to mortality and graft failure in liver transplants. A total of 2,666 patients, 18 years or older, (1,482 males; 1,184 females) were investigated. Outcome variables included mortality and graft failure rates, which were grouped into a single binary variable called negative outcome rate. Additionally, donor clinical, laboratory, intensive care, and organ characteristics and recipient clinical data were analyzed. The mortality rate was 16.2 per 100 person-years (py) (95% CI: 15.1-17.3), and the graft failure rate was 1.8 per 100 py (95% CI: 1.5-2.2). Thus, the negative outcome rate was 18.0 per 100 py (95% CI: 16.9-19.2). The best risk model demonstrated that recipient creatinine ≥ 2.11 mg/dl [RR = 1.80 (95% CI: 1.56-2.08)], total bilirubin ≥ 2.11 mg/dl [RR = 1.48 (95% CI: 1.27-1.72)], Na+ ≥ 141.01 mg/dl [RR = 1.70 (95% CI: 1.47-1.97)], RNI ≥ 2.71 [RR = 1.64 (95% CI: 1.41-1.90)], body surface ≥ 1.98 [RR = 0.81 (95% CI: 0.68-0.97)] and donor age ≥ 54 years [RR = 1.28 (95% CI: 1.11-1.48)], male gender [RR = 1.19(95% CI: 1.03-1.37)], dobutamine use [RR = 0.54 (95% CI: 0.36-0.82)] and intubation ≥ 6 days [RR = 1.16 (95% CI: 1.10-1.34)] affected the negative outcome rate. CONCLUSIONS The current study confirms that both donor and recipient characteristics must be considered in post-transplant outcomes and prognostic scores. Our data demonstrated that recipient characteristics have a greater impact on post-transplant outcomes than donor characteristics. This new concept makes liver transplant teams to rethink about the limits in a MELD allocation system, with many teams competing with each other. The results suggest that although we have some concerns about the donors features, the recipient factors were heaviest predictors for bad outcomes.

Amelioration of Hyperbilirubinemia in Gunn Rats after Transplantation of Human Induced Pluripotent Stem Cell-Derived Hepatocytes. Stem Cell Reports 2015; 5:22-30.

Abstract
Hepatocyte transplantation has the potential to cure inherited liver diseases, but its application is impeded by a scarcity of donor livers. Therefore, we explored whether transplantation of hepatocyte-like cells (iHeps) differentiated from human induced pluripotent stem cells (iPSCs) could ameliorate inherited liver diseases. iPSCs reprogrammed from human skin fibroblasts were differentiated to iHeps, which were transplanted into livers of uridinediphosphoglucuronate glucuronosyltransferase-1 (UGT1A1)-deficient Gunn rats, a model of Crigler-Najjar syndrome 1 (CN1), where elevated unconjugated bilirubin causes brain injury and death. To promote iHep proliferation, 30% of the recipient liver was X-irradiated before transplantation, and hepatocyte growth factor was expressed. After transplantation, UGT1A1+ iHep clusters constituted 2.5%–7.5% of the preconditioned liver lobe. A decline of serum bilirubin by 30%–60% and biliary excretion of bilirubin glucuronides indicated that transplanted iHeps expressed UGT1A1 activity, a postnatal function of hepatocytes. Therefore, iHeps warrant further exploration as a renewable source of hepatocytes for treating inherited liver diseases. Human skin fibroblast-derived iPSCs were differentiated to hepatocyte-like iHeps iHeps were transplanted into Gunn rats, a model of Crigler-Najjar syndrome 1 Engraftment of the iHeps in Gunn rat livers reduced serum bilirubin levels iHeps may be potentially useful in treating liver-based metabolic disorders

Elevation of HO-1 Expression Mitigates Intestinal Ischemia-Reperfusion Injury and Restores Tight Junction Function in a Rat Liver Transplantation Model. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2015; 2015:986075. [PMID: 26064429 PMCID: PMC4441991 DOI: 10.1155/2015/986075] [Citation(s) in RCA: 71] [Impact Index Per Article: 7.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/11/2015] [Accepted: 04/26/2015] [Indexed: 12/17/2022]
Abstract
Aims. This study was aimed at investigating whether elevation of heme oxygenase-1 (HO-1) expression could lead to restoring intestinal tight junction (TJ) function in a rat liver transplantation model. Methods. Intestinal mucosa injury was induced by orthotopic autologous liver transplantation (OALT) on male Sprague-Dawley rats. Hemin (a potent HO-1 activator) and zinc-protoporphyrin (ZnPP, a HO-1 competitive inhibitor), were separately administered in selected groups before OALT. The serum and intestinal mucosa samples were collected at 8 hours after the operation for analysis. Results. Hemin pretreatment significantly reduced the inflammation and oxidative stress in the mucosal tissue after OALT by elevating HO-1 protein expression, while ZnPP pretreatment aggravated the OALT mucosa injury. Meanwhile, the restriction on the expression of tight junction proteins zonula occludens-1 and occludin was removed after hemin pretreatment. These molecular events led to significant improvement on intestinal barrier function, which was proved to be through increasing nuclear translocation of nuclear factor-E2-related factor 2 (Nrf2) and reducing nuclear translocation of nuclear factor kappa-B (NF-κB) in intestinal injured mucosa. Summary. Our study demonstrated that elevation of HO-1 expression reduced the OALT-induced intestinal mucosa injury and TJ dysfunction. The HO-1 protective function was likely mediated through its effects of anti-inflammation and antioxidative stress.

Abstract
PURPOSE OF REVIEW Aging is a condition in which a person gradually loses the ability to maintain homeostasis, due to structural alteration or dysfunction. Aging is a major risk factor for most chronic diseases. As the liver has a remarkable ability to regenerate, this review assessed the effect of aging on clinical liver disease with references to preclinical models when relevant to pathogenesis. RECENT FINDINGS Aging has been shown to not only enhance vulnerability to acute liver injury but also increase susceptibility of the fibrotic response. Aging is associated with the severity and poor prognosis of various liver diseases including nonalcoholic fatty liver disease, alcoholic liver disease, hepatitis C, and liver transplantation. SUMMARY Treatment of older patients with liver disease may require different or longer interventions. Transplantation of an older liver will be less tolerant of subsequent injury. Future studies are needed to understand more about the molecular mechanism of aging and contribute to the development of a noble treatment strategy that can block the progression of aging-induced liver diseases.

Bone marrow-derived mesenchymal stem cells attenuate acute liver injury and regulate the expression of fibrinogen-like-protein 1 and signal transducer and activator of transcription 3.

Abstract
In recent years, bone marrow-derived mesenchymal stem cells (BMSCs) have been demonstrated to exert extensive therapeutic effects on acute liver injury; however, the underlying mechanisms of these effects have remained to be elucidated. The present study focused on the potential anti-apoptotic and pro-regenerative effects of BMSCs in D-galactosamine (D-Gal) and lipopolysaccharide (LPS)-induced acute liver injury in rats. An experimental rat acute liver injury model was established by intraperitoneal injection of D-Gal (400 mg/kg) and LPS (80 μg/kg). BMSCs and an identical volume of saline were administered via the caudal vein 2 h after the D-Gal and LPS challenge. Subsequently, the serum samples were collected to detect the levels of alanine aminotransferase and aspartate aminotransferase. Hematoxylin and eosin staining, terminal deoxynucleotidyl transferase-mediated nick-end labeling assay and immunohistochemical staining were performed to determine apoptosis, regeneration and histological changes of liver sections. Western blotting and reverse transcription-quantitative polymerase chain reaction were performed to detect the protein and mRNA expression levels of fibrinogen-like-protein 1 (FGL1), phosphorylated signal transducer and activator of transcription 3 (p-STAT3), STAT3 and B-cell lymphoma 2 (Bcl-2) and Bcl-2 associated X protein (Bax) in liver tissue samples. The results indicated that intravenous transplantation of BMSCs significantly decreased the levels of alanine aminotransferase and aspartate aminotransferase, and reduced hepatocellular necrosis and inflammatory cell infiltration. Additionally, a terminal deoxynucleotidyl transferase-mediated nick-end labeling assay and immunohistochemical staining revealed that BMSC treatment reduced hepatocyte apoptosis and enhanced liver regeneration. Furthermore, Bcl-2 expression was increased, whilst the protein expression of Bax was reduced. The expression of FGL1 and p-STAT3 were elevated concurrently with the improvement of liver function. These results demonstrated that BMSCs may provide a promising potential agent for the prevention of acute liver injury via inhibition of hepatocyte apoptosis and acceleration of liver regeneration. The mechanism may be, a least in part, a consequence of the upregulation of FGL1 expression and the induction of STAT3 phosphorylation.

Abstract
Donor-transmitted disease in organ transplantation is uncommon, but possible. The LDL receptor (LDLR), a key regulator of lipoprotein metabolism, is abundant in the liver. Mutations in the LDLR gene, leading to reduced LDLR activity, are the main cause for familial hypercholesterolemia (FH). The estimated prevalence of FH is 1/200-1/500 in the population indicating that there are 14-34 million individuals with FH worldwide. We describe a patient who developed severe hypercholesterolemia after liver transplantation (LT). The 42-year-old female, who was transplanted because of hepatic epithelioid hemangioendothelioma with normal liver function, exhibited an increase in plasma total cholesterol from 5.6 mmol/L (217 mg/dL) pretransplant to 11.7 mmol/L (452 mg/dL) at 6 months posttransplant. The respective increase in LDL cholesterol was from 3.30 (128 mg/dL) to 8.99 mmol/L (348 mg/dL). At 1 year, total and LDL cholesterol levels were 11.0 (425 mg/dL) and 7.81 (302 mg/dL), respectively. Sequencing of the coding region of LDLR from a liver graft biopsy revealed a splicing heterozygous mutation of LDLR, whereas no FH-related mutation was found in DNA extracted from the patient's blood white cells. This confirmed the first reported case of a patient receiving a mutation in LDLR through LT. The case shows that a donor-transmitted disorder should not be overlooked as a possible cause for severe hypercholesterolemia.

Abstract
Background Liver transplantation (LT) is the treatment of choice for chronic and acute liver failure; however, the status of long-term survivors and allograft function is not well known. Aim To evaluate the clinical outcome and allograft function of survivors 20 years post-LT, cause of death during the same period and risk factors of mortality. Methods A retrospective study was conducted from prospective, longitudinal data collected at a single center of adult LT recipients surviving 20 years. A comparative sub-analysis was made with patients who were not alive 20 years post-transplantation to identify the causes of death and risk factors of mortality. Results Between 1988 and 1994, 132 patients received 151 deceased-donors LT and 28 (21 %) survived more than 20 years. Regarding liver function in this group, medians of AST, ALT and total bilirubin at 20 years post-LT were 33 IU/L (13–135 IU/L), 27 (11–152 IU/L) and 0.6 mg/dL (0.3–1.1 mg/dL). Renal dysfunction was observed in 40 % of patients and median eGFR among 20-year survivors was 64 mL/min/1.73 m2 (6–144 mL/min/1.73 m2). Sixty-one percent of 20-year survivors had arterial hypertension, 43 % dyslipidemia, 25 % de novo tumors and 21 % diabetes mellitus. Infections were the main cause of death during the 1st year post-transplant (32 %) and between the 1st and 5th year post-transplant (25 %). After 5th year from transplant, hepatitis C recurrence (22 %) became the first cause of death. Factors having an impact on long-term patient survival were HCC indication (p = 0.049), pre-transplant renal dysfunction (p = 0.043) and long warm ischemia time (p = 0.016); furthermore, post-transplant factors were diabetes mellitus (p = 0.001) and liver dysfunction (p = 0.05) at 1 year. Conclusion Our results showed the effect of immunosuppression used during decades on long-term outcome in our LT patients in terms of morbidity (arterial hypertension, diabetes mellitus, dyslipidemia and renal dysfunction) and mortality (infections and hepatitis C recurrence).

Abstract
BACKGROUND Reported 10-year patient survival after liver transplantation is nearing 70 percent, with similar trends seen for kidney transplantation. With increasing life expectancy, these patients have an increased need for posttransplant reconstructive surgery. Thus, plastic surgeons must know the effects of immunosuppressive medications on outcomes in microvascular reconstruction. METHODS A retrospective review was performed on all immunosuppressed solid-organ transplant patients who underwent subsequent free tissue transfer of all types, over an 8-year period. Patient demographics, type of solid organ transplant, immunosuppressive regimen, anticoagulation regimen, associated medical comorbidities, and complication rates were analyzed. RESULTS Twenty-four microvascular free tissue transfers were performed over an 8-year period on immunosuppressed patients, for head and neck and lower extremity reconstruction. Fifteen patients (63 percent) underwent prior kidney transplant, seven (29 percent) underwent prior liver transplant, and two (8 percent) underwent prior lung transplant. Prednisone (79 percent of patients), cyclosporine (33 percent), and tacrolimus (33 percent) were the most commonly used immunosuppressive medications. Complications included one total flap loss (4 percent), three intraoperative arterial thromboses (13 percent), and two postoperative venous thromboses (8 percent). Univariate analysis illustrated a statistically significant association between prednisone and overall complication rate (p = 0.032). CONCLUSIONS Microvascular free tissue transfer is a challenge in immunosuppressed patients. Univariate analysis showed prednisone to correlate statistically with operative morbidity. Transplant patients receiving prednisone at the time of their elective free flap procedure will require additional care to lower the additional risk of delayed wound healing, partial flap loss, and anastomotic thrombosis.

Abstract
In this study, we describe a cohort of patients who received liver transplants before January 1, 1989 at the University of Minnesota Medical Center (UMMC), and we evaluate the health-related quality of life (HRQOL) of the survivors of this group. One hundred sixty-one patients--66 adults and 95 children--received whole deceased donor liver transplants. Thirteen transplants occurred before 1980, and all these patients died within 6 months; they were excluded from the survival analysis because they came from the pre-cyclosporine era. The survival rates at 1, 5, 10, and 20 years were 72%, 57%, 49%, and 37%, respectively (34% when pre-1980 patients were included). The median survival time was approximately 10 years for adult and pediatric recipients. The causes of death were ascertained by chart reviews. Technical failures were common between the years 1980 and 1984, and they decreased to 0% by 1988. As for HRQOL, 53 patients (36%) survived and were contacted to complete a 12-item health survey [Short Form 12 (SF-12)]. Retransplants were excluded. Sixty-eight percent returned the SF-12 survey. The median age for all respondents was 31.4 years: the median was 67.4 years for adult survivors and 28.8 years for pediatric survivors. The Mental Component Summary (MCS) score was 54.6 for adult survivors and 48.6 for pediatric survivors. The Physical Component Summary (PCS) score was 39.3 for adult survivors and 49.2 for pediatric survivors. Both the MCS and the PCS were norm-based to the US population with a mean of 50 and a standard deviation of 10. In conclusion, 35.8% of liver transplant recipients from UMMC were alive 20 years after liver transplantation. Technical failure-related deaths decreased dramatically from 1980 to 1988. The mental health of pediatric and adult survivors was similar to that of the general population. The physical health of the pediatric survivors was equivalent to that of the general population, but it was slightly less than what was expected with adjustments for age. The physical health of the adult survivors was approximately 1 standard deviation below that of the general population.

BACKGROUND AND AIM Pre-transplant sarcopenia (reduced skeletal muscle mass) predicts poor outcome in cirrhosis. In contrast, whether muscle mass increases post-orthotopic liver transplantation (OLT) is not known and was studied prospectively. METHODS Consecutive patients who underwent a comprehensive nutritional evaluation in a liver transplant nutrition clinic were included. Core abdominal muscle area was measured on abdominal computed tomography obtained pre- and post-OLT. Age- and gender-based controls were used to define sarcopenia. Measures of body composition pre-transplant were correlated with computed tomography measurements. Predictors and clinical impact of post-OLT change in muscle area were examined. In three subjects post-OLT and three controls, expression of genes regulating skeletal muscle mass were quantified. RESULTS During the study period, 53 patients (M:F 41:12; age 56.9 ± 7.5 years) were followed up after OLT for 19.3 ± 9 months. Five patients died and another five had acute graft rejection. Pre-OLT sarcopenia was present in 33 (66.2%). Pre-transplant clinical characteristics including Child's score, MELD score, and nutritional status or post-transplantation immunosuppression regimen did not predict post-transplant change in muscle mass. New onset post-OLT sarcopenia developed in 14 patients. Loss of muscle mass post-OLT increased risk of diabetes mellitus and a trend toward higher mortality. Skeletal muscle expression of myostatin was higher and that of ubiquitin proteasome proteolytic components lower post-OLT than in controls. CONCLUSIONS Post-transplantation sarcopenia is common and could not be attributed to pre-transplant characteristics or the type or duration of post-OLT immunosuppression. Post-transplant sarcopenia contributes to adverse consequences and strategies targeting myostatin may be beneficial.

Machine perfusion in solid organ transplantation: where is the benefit? Langenbecks Arch Surg 2014; 399:421-7.

Abstract
BACKGROUND Machine perfusion (MP) in solid organ transplantation has been a topic of variable importance for decades. At the dawn of organ transplantation, MP was one of the standard techniques for preservation; today's gold standard for organ preservation for transplantation is cold storage (CS). The outcome after transplantation of solid organs has tremendously improved over the last five decades. MP has been continuously under investigation and may be an option for organ preservation in selected cases; however, there is only little evidence from clinical trials that can be used to advocate for MP as a routine organ preservation method. METHODS This article reviews the current knowledge on MP in the field of solid organ transplantation with special focus on findings from clinical trials. CONCLUSION Especially in heart and lung transplantation, MP seems to be a promising tool to improve postoperative outcome, but a general evidence-based recommendation for or against an application of MP cannot be given due to the lack of the highest level of clinical evidence. Gold standards such as CS should not be left behind without good reason. Randomized clinical trials are desperately needed to further improve outcome and for better understanding of the underlying pathophysiological mechanisms.

Abstract
Liver transplantation is believed to reverse the clinical and metabolic abnormalities of cirrhosis. Reduced skeletal muscle mass or sarcopenia contributes to increased mortality and adverse consequences of cirrhosis. Failure of reversal of sarcopenia of cirrhosis after liver transplantation is not well recognized. Six temporally, geographically, and methodologically distinct follow-up studies in 304 cirrhotics reported conflicting data on changes in indirect measures of skeletal muscle mass after transplantation. Distinct measures of body composition but not skeletal muscle mass were used and did not focus on the clinical consequences of sarcopenia after transplantation. A number of studies reported an initial rapid postoperative loss of lean mass followed by incomplete recovery with a maximum follow-up of 2 years. Posttransplant sarcopenia may be responsible for metabolic syndrome and impaired quality of life after liver transplantation. Potential reasons for failure to reverse sarcopenia after liver transplantation include use of immunosuppressive agents [mammalian target of rapamycin (mTOR) and calcineurin inhibitors] that impair skeletal muscle growth and protein accretion. Repeated hospitalizations, posttransplant infections, and renal failure also contribute to posttransplant sarcopenia. Finally, recovery from muscle deconditioning is limited by lack of systematic nutritional and physical-activity-based interventions to improve muscle mass. Despite the compelling data on sarcopenia before liver transplantation, the impact of posttransplant sarcopenia on clinical outcomes is not known. There is a compelling need for studies to examine the mechanisms and consequences of sarcopenia post liver transplantation to permit development of therapies to prevent and reverse this disorder.

Abstract
BACKGROUND Ischemia-reperfusion (I/R) injury is associated with intestinal microbial dysbiosis. The "gut-liver axis" closely links gut function and liver function in health and disease. Ischemic preconditioning (IPC) has been proven to reduce I/R injury in the surgery. This study aims to explore the effect of IPC on intestinal microbiota and to analyze characteristics of microbial structure shift following liver transplantation (LT). METHODS The LT animal models of liver and gut IPC were established. Hepatic graft function was assessed by histology and serum ALT/AST. Intestinal barrier function was evaluated by mucosal ultrastructure, serum endotoxin, bacterial translocation, fecal sIgA content and serum TNF-α. Intestinal bacterial populations were determined by quantitative PCR. Microbial composition was characterized by DGGE and specific bacterial species were determined by sequence analysis. PRINCIPAL FINDINGS Liver IPC improved hepatic graft function expressed as ameliorated graft structure and reduced ALT/AST levels. After administration of liver IPC, intestinal mucosal ultrastructure improved, serum endotoxin and bacterial translocation mildly decreased, fecal sIgA content increased, and serum TNF-α decreased. Moreover, liver IPC promoted microbial restorations mainly through restoring Bifidobacterium spp., Clostridium clusters XI and Clostridium cluster XIVab on bacterial genus level. DGGE profiles indicated that liver IPC increased microbial diversity and species richness, and cluster analysis demonstrated that microbial structures were similar and clustered together between the NC group and Liver-IPC group. Furthermore, the phylogenetic tree of band sequences showed key bacteria corresponding to 10 key band classes of microbial structure shift induced by liver IPC, most of which were assigned to Bacteroidetes phylum. CONCLUSION Liver IPC cannot only improve hepatic graft function and intestinal barrier function, but also promote restorations of intestinal microbiota following LT, which may further benefit hepatic graft by positive feedback of the "gut-liver axis".

Abstract
Liver and kidney transplantations have been performed for almost 50 years and is nowadays a routine procedure for the treatment of terminal liver failure and terminal-stage renal failure. Under given optimal conditions and increasing experience good results can be achieved. Improvements in surgical techniques have led to a decrease in the incidence of surgical complications after transplantation. Nevertheless after liver and kidney transplantation complications can occur and increase the morbidity and mortality. There are a number of possible complications which range from harmless wound healing disorders to severe vascular, biliary or urinary complications that can be associated with graft dysfunction and lead to graft loss. In order to identify risk factors preoperatively and achieve good outcome after transplantation a good preparation of the recipients is necessary. Furthermore, a good interdisciplinary cooperation is necessary both to recognize complications early and to treat these adequately.

Abstract
With excellent short-term survival in liver transplantation (LT), we now focus on long-term outcome and report the first European single-center 20-year survival data. Three hundred thirty-seven LT were performed in 313 patients (09/88-12/92). Impact on long-term outcome was studied and a comparison to life expectancy of matched normal population was performed. A detailed analysis of 20-years follow-up concerning overweight (HBMI), hypertension (HTN), diabetes (HGL), hyperlipidemia (HLIP) and moderately or severely impaired renal function (MIRF, SIRF) is presented. Patient and graft survival at 1, 10, 20 years were 88.4%, 72.7%, 52.5% and 83.7%, 64.7% and 46.6%, respectively. Excluding 1-year mortality, survival in the elderly LT recipients was similar to normal population. Primary indication (p < 0.001), age (p < 0.001), gender (p = 0.017), impaired renal function at 6 months (p < 0.001) and retransplantation (p = 0.034) had significant impact on patient survival. Recurrent disease (21.3%), infection (20.6%) and de novo malignancy (19.9%) were the most common causes of death. Prevalence of HTN (57.3-85.2%, p < 0.001), MIRF (41.8-55.2%, p = 0.01) and HBMI (33.2-45%, p = 0.014) increased throughout follow-up, while prevalence of HLIP (78.0-47.6%, p < 0.001) declined. LT has conquered many barriers to achieve these outstanding long-term results. However, much work is needed to combat recurrent disease and side effects of immunosuppression (IS).

Abstract
Recipients of liver transplantation (LT) receive lifelong immunosuppression, which causes side effects. We investigated self-reported oral symptoms and associated risk factors with the following hypothesis: symptoms and signs would differ between LT recipients of different etiology groups and also between LT recipients and a control population. Eighty-four LT recipients (64 with chronic liver disease and 20 with acute liver disease) were recruited for clinical oral and salivary examinations (median follow-up = 5.7 years). A structured questionnaire was used to record subjective oral symptoms. Matched controls (n = 252) came from the National Finnish Health 2000 survey. The prevalence of symptoms was compared between the groups, and the risk factors for oral symptoms were analyzed. Xerostomia was prevalent in 48.4% of the chronic LT recipients and in 42.1% of the acute LT recipients. This subjective feeling of dry mouth was only partly linked to objectively measured hyposalivation. The chronic transplant recipients had significantly lower unstimulated salivary flow rates than the acute transplant recipients (0.34 ± 0.31 versus 0.61 ± 0.49 mL/minute, P = 0.005). Among the chronic transplant recipients, hyposalivation with unstimulated salivary flow was associated with fewer teeth (17.7 ± 8.2 versus 21.9 ± 8.4, P = 0.047) and more dentures (33.3% versus 12.2%, P = not significant). The chronic patients reported significantly more dysphagia than their controls (23.4% versus 11.5%, P = 0.02). Increases in the number of medications increased the symptoms in all groups. In conclusion, dysphagia was significantly more prevalent among the chronic LT recipients versus the controls. The number of medications was a risk factor for dry mouth-related symptoms for both the LT recipients and the controls. The chronic transplant recipients presented with lower salivary flow rates than the acute transplant recipients. Hyposalivation correlated with generally worse oral health among the chronic transplant recipients. These differences between the chronic and acute LT recipients may have been due to differences in their medical conditions due to the different etiologies.

Abstract
The management of non-melanoma skin cancers (NMSCs) in solid organ transplant recipients (OTRs) presents a variety of clinical challenges for physicians. OTRs are at a 65-fold increased risk for developing cutaneous squamous cell carcinomas (SCC), the most common NMSC that develops after transplantation. Risk factors contributing to the development of NMSCs in OTRs include a past medical history of any previous skin cancer, a personal history of significant sun exposure and a fair skin complexion or phototype. Further, greater immunosuppressive medication levels lead to an increased risk of NMSCs. Among immunosuppressants, specific older agents such as azathioprine and cyclosporine may increase the risk of developing NMSCs in contrast to newer agents such as sirolimus. Early skin biopsy and treatment of premalignant and malignant lesions are essential for treating these patients successfully. In this regard, the concept of field cancerization has been instructive in broadening treatments to include entire affected areas rather than individual lesions given that the areas with significant ultraviolet irradiation will continue to develop numerous individual precancerous and cancerous lesions. Field therapy with photodynamic therapy or topical 5-fluorouracil, imiquimod or diclofenac is often used in OTRs according to individual patient tolerability. Prompt excision or Mohs micrographic surgery is the standard of care of primary, uncomplicated squamous cell and basal cell carcinomas. For patients with in-transit or metastatic squamous cell carcinomas, adjuvant radiation, chemotherapy, and staging by sentinel lymph node dissection may be employed. For patients who develop numerous SCC per year, chemoprophylaxis can be effective in limiting the burden of disease. In consultation with the multidisciplinary transplant team, the immunosuppressive regimen can be revised to lower overall immunosuppression or altered to include newer drugs that have decreased oncogenic potential in OTRs. The greatest impact may be made by the prevention of NMSCs through simple, but rigorous, patient education on the benefits of UV protection, periodic self-skin examinations, and regular follow-ups. Accordingly, vitamin D and calcium supplementation should also be incorporated in transplant recipients. Management of OTRs requires patient education, frequent motivation for vigilance, regular follow-up, and interdisciplinary collaboration between transplant surgeons, nephrologists, hepatologists, cardiologists, transplant nurses, dermatologists, oncologists, pharmacists, and other relevant physicians ideally orchestrated by the essential transplant coordinators.

Vorinostat, an HDAC inhibitor attenuates epidermoid squamous cell carcinoma growth by dampening mTOR signaling pathway in a human xenograft murine model. Toxicol Appl Pharmacol 2012; 266:233-44.

Abstract
Histone deacetylase (HDAC) inhibitors are potent anticancer agents and show efficacy against various human neoplasms. Vorinostat is a potent HDAC inhibitor and has shown potential to inhibit growth of human xenograft tumors. However, its effect on the growth of skin neoplasm remains undefined. In this study, we show that vorinostat (2 μM) reduced expression of HDAC1, 2, 3, and 7 in epidermoid carcinoma A431 cells. Consistently, it increased acetylation of histone H3 and p53. Vorinostat (100mg/kg body weight, IP) treatment reduced human xenograft tumor growth in highly immunosuppressed nu/nu mice. Histologically, the vorinostat-treated tumor showed features of well-differentiation with large necrotic areas. Based on proliferating cell nuclear antigen (PCNA) staining and expression of cyclins D1, D2, E, and A, vorinostat seems to impair proliferation by down-regulating the expression of these proteins. However, it also induced apoptosis. The mechanism by which vorinostat blocks proliferation and makes tumor cells prone to apoptosis, involved inhibition of mTOR signaling which was accompanied by reduction in cell survival AKT and extracellular-signal regulated kinase (ERK) signaling pathways. Our data provide a novel mechanism-based therapeutic intervention for cutaneous squamous cell carcinoma (SCC). Vorinostat may be utilized to cure skin neoplasms in organ transplant recipient (OTR). These patients have high morbidity and surgical removal of these lesions which frequently develop in these patients, is difficult.
