[PMID: 38661296 DOI: 10.1111/liv.15908] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/24/2023] [Revised: 02/03/2024] [Accepted: 03/10/2024] [Indexed: 04/26/2024]
Abstract
BACKGROUND AND AIMS The presence of steatosis in a donor liver and its relation to post-transplantation outcomes are not well defined. This study evaluates the effect of the presence and severity of micro- and macro-steatosis of a donor graft on post-transplantation outcomes. METHODS The UNOS-STAR registry (2005-2019) was used to select patients who received a liver transplant graft with hepatic steatosis. The study cohort was stratified by the presence of macro- or micro-vesicular steatosis, and further stratified by histologic grade of steatosis. The primary endpoints of all-cause mortality and graft failure were compared using sequential Cox regression analysis. Analysis of specific causes of mortality was further performed. RESULTS There were 9184 with no macro-steatosis (control), 150 with grade 3 macro-steatosis, 822 with grade 2 macro-steatosis and 12 585 with grade 1 macro-steatosis. There were 10 320 without micro-steatosis (control), 478 with grade 3 micro-steatosis, 1539 with grade 2 micro-steatosis and 10 404 with grade 1 micro-steatosis. There was no significant difference in all-cause mortality or graft failure among recipients who received a donor organ with any evidence of macro- or micro-steatosis, compared to those receiving non-steatotic grafts. There was increased mortality due to cardiac arrest among recipients of a grade 2 macro-steatosis donor organ. CONCLUSION This study shows no significant difference in all-cause mortality or graft failure among recipients who received a donor liver with any degree of micro- or macro-steatosis. Further analysis identified increased mortality due to specific aetiologies among recipients receiving donor organs with varying grades of macro- and micro-steatosis.

Abstract
BACKGROUND In Italy, data on long-term survivors after liver transplantation are lacking. MATERIALS AND METHODS We conducted a hybrid design study on a cohort of 359 adult recipients who received transplants between 1996 and 2002 to identify predictors of survival and the prevalence of co-morbidities among long-term survivors. RESULTS The actuarial (95% CI) patient survival was 96% (94.6-98.3%), 69% (64.2-73.6%), 55% (49.8-59.9%), 42.8% (37.6-47.8%), and 34% (29.2-38.9%) at 1, 5, 10, 15, and 20 years, respectively. The leading causes of death were hepatitis C virus recurrence (24.6%), extrahepatic malignancies (16.9%), infection (14.4%), and hepatocellular carcinoma recurrence (14.4%). The factors associated with the survival probability were younger donor and recipient ages (p = 0.001 and 0.004, respectively), female recipient sex (p < 0.001), absence of HCV (p < 0.01), absence of HCC (p = 0.001), and absence of diabetes mellitus at one year (p < 0.01). At the latest follow-up, the leading comorbidities were hypertension (53.6%), obesity (18.7%), diabetes mellitus (17.1%), hyperlipidemia (14.7%), chronic kidney dysfunction (14.7%), and extrahepatic malignancies (13.8%), with 73.9% of patients having more than one complication. CONCLUSIONS Aging with a liver graft is associated with an increased risk of complications and requires ongoing care to reduce the long-term attrition rate resulting from chronic immunosuppression.

Transl Res 2024; 264:33-65. [PMID: 37722450 DOI: 10.1016/j.trsl.2023.09.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/20/2023] [Revised: 09/06/2023] [Accepted: 09/06/2023] [Indexed: 09/20/2023]
Abstract
Orthotopic liver transplantation (OLT) is a lifesaving procedure. However, grafts may fail due to primary nonfunction (PNF). In the past, we demonstrated PNFs to be mainly associated with fatty allografts, and given its unpredictable nature, the development of a disease model is urgently needed. In an effort to investigate mechanism of fatty allograft-associated PNFs, we induced fatty liver disease in donor animals by feeding rats a diet deficient in methionine and choline (MCD). We performed OLT with allografts of different grades of hepatic steatosis and compared the results to healthy ones. We assessed liver function by considering serum biochemistries, and investigated genome wide responses following OLT of healthy and fatty allograft-associated PNFs. Furthermore, we performed immunohistochemistry to evaluate markers of oxidative stress and reperfusion injury, inflammation, glycolysis and gluconeogenesis, lactate transport, and its utilization as part of the Cori cycle. Strikingly, PNFs are strictly lipid content dependent. Nonetheless, a fat content of ≤17% and an increase in the size of hepatocytes of ≤11% (ballooning) greatly improved outcome of OLTs and the hepatic microcirculation. Mechanistically, PNFs arise from a dysfunctional Cori cycle with complete ablation of the lactate transporter SLC16A1. Thus, lipid-laden hepatocytes fail to perform gluconeogenesis via lactate reutilization, and the resultant hyperlactatemia and lactic acidosis causes cardiac arrhythmogenicity and death. Furthermore, the genomic and immunohistochemistry investigations underscore a dysfunctional Krebs cycle with impaired energy metabolism in lipid-burdened mitochondria. Together, we show fatty allografts to be highly vulnerable towards ischemia/reperfusion-injury, and stabilizing the Cori cycle is of critical importance to avert PNFs.

Abstract
The long-term (>5 y) outcomes following liver transplantation (LT) have not been extensively reported. The aim was to evaluate outcomes of LT recipients who have survived the first 5 years. A multicenter retrospective analysis of prospectively collected data from 3 high volume LT centers (Dallas-USA, Birmingham-UK, and Barcelona-Spain) was undertaken. All adult patients, who underwent LT since the inception of the program to December 31, 2010, and survived at least 5 years since their LT were included. Patient survival was the primary outcome. A total of 3682 patients who survived at least 5 years following LT (long-term survivors) were included. Overall, median age at LT was 52 years (IQR 44-58); 53.1% were males; and 84.6% were Caucasians. A total of 49.4% (n=1820) died during a follow-up period of 36,828 person-years (mean follow-up 10 y). A total of 80.2% (n=1460) of all deaths were premature deaths. Age-standardized all-cause mortality as compared to general population was 3 times higher for males and 5 times higher for females. On adjusted analysis, besides older recipients and older donors, predictors of long-term mortality were malignancy, cardiovascular disease, and dialysis. Implementation of strategies such as noninvasive cancer screening, minimizing immunosuppression, and intensive primary/secondary cardiovascular prevention could further improve survival.

Abstract
BACKGROUND Epidemiological studies on liver transplant (LT) patients can provide valuable information about the etiology and trends of cirrhosis. The present study aimed to investigate the prevalence and trend of different etiologies and survival rates of LT patients at the Namazi Transplant Center in Shiraz, Iran, between 2001 and 2018. METHODS In this single-center, retrospective cohort study, the demographic and clinical characteristics of 3751 patients who underwent LT and met the study inclusion criteria, including age, gender, blood group, body mass index, model for end-stage liver disease (MELD) score, cause of cirrhosis, and diabetes, were extracted from patients' physical or electronic medical records between 2001 and 2018. RESULTS The MELD scores of LT patients with primary sclerosing cholangitis (PSC), hepatitis B virus (HBV), and non-alcoholic steatohepatitis (NASH) cirrhosis significantly decreased over the study period (P<0.001). Among the LT patients, HBV infection had the highest frequency (21.09%), followed by cryptogenic (17.33%) and PSC (17.22%). The proportion of patients with PSC and NASH (both P<0.001) cirrhosis was significantly increased, so that PSC cirrhosis (2016: 19.4%, 2018: 18.8%) surpassed HBV (2016: 18.4%, 2018: 13.5%), autoimmune hepatitis (2016: 11.7%, 2018: 12.7%), and cryptogenic cirrhosis (2016: 16.1%, 2018:14%) as the leading indication for LT from 2016 to the end of the study period. Fortunately, these patients had a better survival rate than other common diseases (HR: 0.53, CI: 0.43‒0.66; P<0.001). CONCLUSION The proportion of NASH and PSC cirrhosis significantly increased during the 18 years of study. However, these patients had an improved survival rate. Therefore, health organizations should pay more attention to non-communicable diseases, especially fatty liver disease and cholangitis.

Abstract
BACKGROUND Liver transplantation (LT) is life-saving procedure for patients with end-stage liver failure with up to 20% of patients suffering graft failure following primary transplantation. Retransplantation (ReLT) remains the only definitive treatment for irreversible graft failure. AIMS We aimed to explore the postoperative outcomes following liver ReLT. METHODS Patients who had received a liver transplant between 2003 and 2016 were retrospectively identified using the Scientific Registry of Transplant Recipients (SRTRs). Patients were stratified based on previous liver transplant history. The primary outcomes of this study were 5-year postoperative mortality, morbidity, and length of hospital stay following LT. RESULTS 60,554 (96%) recipients were first LT recipients and 2524 (4%) were ReLT recipients. Compared with first LT, ReLT recipients had significantly higher rates of mortality (OR 1.93, 95%CI 1.76-2.12), overall morbidity (OR 1.80, 95%CI 1.65-1.96), and prolonged length of stay (OR 1.66, 95%CI 1.52-1.81) on multivariate analysis. Morbidity including cardiovascular (CVD) complications (OR 1.32, 95%CI 1.08-1.60), graft failure (OR 2.18, 95%CI 1.84-2.57), infection (OR 2.13, 95%CI 1.82-2.50), and hemorrhage (OR 2.67, 95%CI 2.00-3.61) were significantly greater in ReLT recipients. Compared to first LT, ReLT patients had a significant increase in overall 5-year mortality (p < 0.001), 5-year mortality due to CVD complications (p < 0.001), infection (p = 0.009), but not graft failure (p = 0.3543). CONCLUSION ReLT is associated with higher rates of 5-year mortality, overall morbidity, CVD morbidity, infection, and graft failure. Higher 5-year mortality in ReLT is due to CVD and infections. These results could be used in preoperative patient assessment and prognostic counseling for ReLT.

Abstract
BACKGROUND To evaluate the influence of preoperative renal function on prognosis after living donor liver transplantation (LDLT). METHODS Living donor liver transplantation cases were categorized into 3 groups as follows: renal failure with hemodialysis (HD; n = 42), renal dysfunction (RD; n = 94) (glomerular filtration rate <60 mL/min/1.73 m2), and normal renal function (NF; n = 421). The study used no prisoners, and participants were neither coerced nor paid. The manuscript complies with the Helsinki Congress and the Declaration of Istanbul. RESULTS Five-year overall survival (OS) rates were 59.0%, 69.3%, and 80.0% in the HD, RD, and NF groups, respectively (P < .01). The frequency of bacteremia within 90 days after LDLT was 76.2%, 37.2%, and 34.7%, respectively (P < .01 in HD vs RD and HD vs NF). Patients with bacteremia showed a worse outcome than those without (1-year OS, 65.6% vs 93.3%), thus corroborating the poor prognosis in the HD group. The high frequency of bacteremia in the HD group was mainly attributable to health care-associated bacterium, such as coagulase-negative Staphylococci, Enterococcus spp., and Pseudomonas aeruginosa. In the HD group, HD was started within 50 days before LDLT for acute renal failure in 35 patients, of which 29 (82.9%) successfully withdrew from HD after LDLT and demonstrated better prognosis (1-year OS, 69.0% vs 16.7%) than those who continued HD. CONCLUSIONS Preoperative renal dysfunction is associated with poor prognosis after LDLT, possibly due to a high incidence of health care-associated bacteremia.

Abstract
BACKGROUND Acute pancreatitis (AP) in liver transplant (LT) recipients may lead to poor clinical outcomes and development of severe complications.
AIM We aimed to assess national trends, clinical outcomes, and the healthcare burden of LT hospitalizations with AP in the United States (US).
METHODS The National Inpatient Sample was utilized to identify all adult (≥ 18 years old) LT hospitalizations with AP in the US from 2007–2019. Non-LT AP hospitalizations served as controls for comparative analysis. National trends of hospitalization characteristics, clinical outcomes, complications, and healthcare burden for LT hospitalizations with AP were highlighted. Hospitalization characteristics, clinical outcomes, complications, and healthcare burden were also compared between the LT and non-LT cohorts. Furthermore, predictors of inpatient mortality for LT hospitalizations with AP were identified. All P values ≤ 0.05 were considered statistically significant.
RESULTS The total number of LT hospitalizations with AP increased from 305 in 2007 to 610 in 2019. There was a rising trend of Hispanic (16.5% in 2007 to 21.1% in 2018, P-trend = 0.0009) and Asian (4.3% in 2007 to 7.4% in 2019, p-trend = 0.0002) LT hospitalizations with AP, while a decline was noted for Blacks (11% in 2007 to 8.3% in 2019, P-trend = 0.0004). Furthermore, LT hospitalizations with AP had an increasing comorbidity burden as the Charlson Comorbidity Index (CCI) score ≥ 3 increased from 41.64% in 2007 to 62.30% in 2019 (P-trend < 0.0001). We did not find statistically significant trends in inpatient mortality, mean length of stay (LOS), and mean total healthcare charge (THC) for LT hospitalizations with AP despite rising trends of complications such as sepsis, acute kidney failure (AKF), acute respiratory failure (ARF), abdominal abscesses, portal vein thrombosis (PVT), and venous thromboembolism (VTE). Between 2007–2019, 6863 LT hospitalizations with AP were compared to 5649980 non-LT AP hospitalizations. LT hospitalizations with AP were slightly older (53.5 vs 52.6 years, P = 0.017) and had a higher proportion of patients with CCI ≥ 3 (51.5% vs 19.8%, P < 0.0001) compared to the non-LT cohort. Additionally, LT hospitalizations with AP had a higher proportion of Whites (67.9% vs 64.6%, P < 0.0001) and Asians (4% vs 2.3%, P < 0.0001), while the non-LT cohort had a higher proportion of Blacks and Hispanics. Interestingly, LT hospitalizations with AP had lower inpatient mortality (1.37% vs 2.16%, P = 0.0479) compared to the non-LT cohort despite having a higher mean age, CCI scores, and complications such as AKF, PVT, VTE, and the need for blood transfusion. However, LT hospitalizations with AP had a higher mean THC ($59596 vs $50466, P = 0.0429) than the non-LT cohort.
CONCLUSION In the US, LT hospitalizations with AP were on the rise, particularly for Hispanics and Asians. However, LT hospitalizations with AP had lower inpatient mortality compared to non-LT AP hospitalizations.

Abstract
Invasive fungal infections represent a major challenge in patients who underwent organ transplantation. Overall, the most common fungal infections in these patients are candidiasis, followed by aspergillosis and cryptococcosis, except in lung transplant recipients, where aspergillosis is most common. Several risk factors have been identified, which increase the likelihood of an invasive fungal infection developing after transplantation. Liver transplant recipients constitute a high-risk category for invasive candidiasis and aspergillosis, and therefore targeted prophylaxis is favored in this patient population. Furthermore, a timely implemented therapy is crucial for achieving optimal outcomes in transplanted patients. In this article, we describe the epidemiology, risk factors, prophylaxis, and treatment strategies of the most common fungal infections in organ transplantation, with a focus on liver transplantation.

Bégin MJ, Ste-Marie LG, Huard G, Dorais M, Räkel A. Increased Imminent Fracture Risk in Liver Transplant Recipients Despite Bisphosphonate Therapy. Transplant Proc 2023; 55:576-585. [PMID: 37012143 DOI: 10.1016/j.transproceed.2023.02.060] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2022] [Revised: 01/29/2023] [Accepted: 02/24/2023] [Indexed: 04/03/2023]
Abstract
BACKGROUND Bone loss is significant after orthotopic liver transplant (OLT) and is associated with increased fracture risk and decreased quality of life. In post-transplant fracture prevention, the cornerstone of therapeutic management is bisphosphonates. METHODS We conducted a retrospective study in a cohort of 155 OLT recipients who received a bisphosphonate prescription at hospital discharge between 2012 and 2016 to investigate post-OLT fragility fracture incidence and predictive risk factors. RESULTS Before OLT, 14 patients presented a T score < -2.5 SD, and 23 patients (14.8%) had a history of fracture. During follow-up, the cumulative incidence of fractures on bisphosphonates (99.4% risedronate/alendronate) was 9.7% at 12 months and 13.1% at 24 months. The median time to first fragility fracture was 10 months (IQR, 3-22 months) and thus within the first 2 years of follow-up. Predictive factors of fragility fractures in multivariate Cox regression analyses included age 60 years or older (hazard ratio [HR], 2.61; 95% CI, 1.14-6.01; P = .02), post-transplant diabetes mellitus (HR, 3.82; 95% CI, 1.55-9.44; P = .004), and cholestatic disease (HR, 5.93; 95% CI, 2.30-15.26; P = .0002). Additionally, the female sex was associated with a strong trend toward increased fracture risk in univariate analysis (HR, 2.27; 95% CI, 1.00-5.15; P = .05), as well as a post-transplant absolute decrease in bone mineral density at the femoral neck and total hip (P = .08). CONCLUSIONS This real-world study reports a high incidence of fractures post-OLT despite bisphosphonate therapy. Age 60 years or older, post-transplant diabetes mellitus, cholestatic disease, female sex, and femoral neck and/or total hip bone mineral density loss contribute to increased imminent fracture risk in liver transplant recipients.

Abstract
Objectives Anastomotic biliary strictures (ABSs) are common complications following living donor liver transplantation (LDLT). We evaluated the feasibility of a novel removable, intraductal, fully covered, self‐expandable metallic stent (FCSEMS) for the treatment of ABSs following LDLT. Methods Nine patients with duct‐to‐duct ABSs that developed following LDLT were prospectively enrolled in this study. We placed a short FCSEMS with a long lasso and middle waist formation in each patient's ABS above the papilla and removed it 16 weeks later. Results The FCSEMS placements were successful in all nine cases. Four patients experienced mild cholangitis, which was resolved with conservative treatment. Additionally, there was one case of distal migration. The FCSEMSs were successfully removed from all the patients, and the clinical success rate was 100%. Stricture recurrence occurred in one (11.1%) patient during the follow‐up period. Limitations The small number and lack of comparison with other types of FCSEMSs and plastic stents. Conclusions Intraductal placement of FCSEMSs is useful for treating refractory ABSs after LDLT, although further studies are required with larger sample sizes.

J Transplant 2023; 2023:3103335.

Abstract
Introduction. Histopathological assessment of liver biopsies is the current “gold standard” for diagnosing graft dysfunction after liver transplantation (LT), as graft dysfunction can have nonspecific clinical presentations and inconsistent patterns of liver biochemical dysfunction. Most commonly, post-LT, graft dysfunction within the first year, is due to acute T-cell mediated rejection (TCMR) which is characterised histologically by the degree of portal inflammation (PI), bile duct damage (BDD), and venous endothelial inflammation (VEI). This study aimed to establish the relationship between global assessment, which is the global grading of rejection using a “gestalt” approach, and the rejection activity index (RAI) of each component of TCMR as described in revised Banff 2016 guidelines. Methods. Liver biopsies (n = 90) taken from patients who underwent LT in 2015 and 2016 at the Australian National Liver Transplant Unit were identified from the electronic medical records. All biopsy slides were microscopically graded by at least two assessors independently using the revised 2016 Banff criteria. Data were analysed using IBM SPSS v21. A Fisher–Freeman–Halton test was performed to assess the correlation between the global assessment and the RAI scores for each TCMR biopsy. Results. Within the cohort, 60 (37%, n = 164) patients underwent at least 1 biopsy within 12 months after LT. The most common biopsy outcome (total n = 90) was acute TCMR (64, 71.1%). Global assessment of TCMR slides strongly positively correlated with PI (
value <0.001), BDD (
value <0.001), VEI (
value <0.001), and total RAI (
value <0.001). Liver biochemistry of patients with TCMR significantly improved within 4 to 6 weeks post-biopsy compared to the day of the biopsy. Conclusion. In acute TCMR, global assessment and total RAI are strongly correlated and can be used interchangeably to describe the severity of TCMR.

Abstract
BACKGROUND Improvement of liver transplantation (LT) outcomes requires better understanding of factors affecting survival. The presence of RBC alloantibodies (RBCAs) on survival in LT recipients was evaluated. METHODS This study was a single-center, retrospective cohort study reviewing transfusion records and all-cause mortality between 2002 and 2021. RESULTS Between 2002 and 2021, 2079 LTs were completed, 1,396 of which met inclusion criteria (1,305 RBCA negative; 91 RBCA positive [6.5%]). The cohorts were similar in age (mean [range], 55.8 [17-79] years vs 56.8 [25-73] years; P = .41, respectively) or sex (RBCA negative, 859 [65%] men and 446 [35%] women vs RBCA positive, 51 [56%] men and 40 [44%] women; P = .0684). Of 132 RBCAs detected, 10 were most common were to E (27.27%), Jka (15.91%), K (9.09%), C (8.33%), M (6.06%), D (5.3%), Fya (4.55%), e (2.27%), c (2.27%), and Jkb (2.27%). Twenty-seven patients (29.7%) had more than 1 RBCA; the most common combinations were C with Jka (7.4%) and E with Dia (7.4%). All-cause mortality was increased in men (men, 14.45 years vs women, 17.27 years; P = .0266) and patients 65 years of age and older (≥65 years of age, 10.21 years vs <64 years of age, 17.22 years; P < .0001). The presence of RBCA (≥1) did not affect all-cause mortality (RBCA negative, 14.17 years vs RBCA positive, 15.29 years; P = .4367). The top 5 causes of death were infection (11.9%), primary malignancy (solid) (10.8%), recurrent malignancy (10.5%), cardiovascular arrest (7.1%), and pulmonary insufficiency/respiratory failure (5.7%). CONCLUSIONS Survival in RBCA-positive LT recipients is no different from that in RBCA-negative LT recipients.

Early γGT and bilirubin levels as biomarkers for regeneration and outcomes in damaged bile ducts after liver transplantation. Clin Transplant 2023; 37:e14880.

Abstract
BACKGROUND Early patient and allograft survival after liver transplantation (LT) depend primarily on parenchymal function, but long-term allograft success relies often on biliary-tree function. We examined parameters related to cholangiocyte damage that predict poor long-term LT outcomes after donation after brain death (DBD). METHODS Sixty bile ducts (BD) were assessed by a BD damage-score and divided into groups with "major" BD-damage (n = 33) and "no relevant" damage (n = 27) during static cold storage. Patients with "major" BD damage were further investigated by measuring biliary excretion parameters in the first 14 days post-LT (followed-up for 60-months). RESULTS Patients who received LT showing "major" BD damage had significantly worse long-term patient survival, versus grafts with "no relevant" damage (p = .03). When "major" BD damage developed, low bilirubin levels (p = .012) and high gamma-glutamyl transferase (GGT)/bilirubin ratio (p = .0003) were evident in the early post-LT phase (7-14 days) in patients who survived (> 60 months), compared to those who did not. "High risk" patients with bile duct damage and low GGT/bilirubin ratio had significantly shorter overall survival (p < .0001). CONCLUSIONS Once "major" BD damage occurs, a high GGT/bilirubin ratio in the early post-operative phase is likely indicator of liver and cholangiocyte regeneration, and thus a harbinger of good overall outcomes. "Major" BD damage without markers of regeneration identifies LT patients that could benefit from future repair therapies.

Incidence of Invasive Fungal Infections in Liver Transplant Recipients under Targeted Echinocandin Prophylaxis. J Clin Med 2023; 12:jcm12041520.

Abstract
Invasive fungal infections (IFIs) are one of the most important infectious complications after liver transplantation, determining morbidity and mortality. Antimycotic prophylaxis may impede IFI, but a consensus on indication, agent, or duration is still missing. Therefore, this study aimed to investigate the incidence of IFIs under targeted echinocandin antimycotic prophylaxis in adult high-risk liver transplant recipients. We retrospectively reviewed all patients undergoing a deceased donor liver transplantation at the Medical University of Innsbruck in the period from 2017 to 2020. Of 299 patients, 224 met the inclusion criteria. We defined patients as being at high risk for IFI if they had two or more prespecified risk factors and these patients received prophylaxis. In total, 85% (190/224) of the patients were correctly classified according to the developed algorithm, being able to predict an IFI with a sensitivity of 89%. Although 83% (90/109) so defined high-risk recipients received echinocandin prophylaxis, 21% (23/109) still developed an IFI. The multivariate analysis identified the age of the recipient (hazard ratio-HR = 0.97, p = 0.027), split liver transplantation (HR = 5.18, p = 0.014), massive intraoperative blood transfusion (HR = 24.08, p = 0.004), donor-derived infection (HR = 9.70, p < 0.001), and relaparotomy (HR = 4.62, p = 0.003) as variables with increased hazard ratios for an IFI within 90 days. The fungal colonization at baseline, high-urgency transplantation, posttransplant dialysis, bile leak, and early transplantation showed significance only in a univariate model. Notably, 57% (12/21) of the invasive Candida infections were caused by a non-albicans species, entailing a markedly reduced one-year survival. The attributable 90-day mortality rate of an IFI after a liver transplant was 53% (9/17). None of the patients with invasive aspergillosis survived. Despite targeted echinocandin prophylaxis, there is still a notable risk for IFI. Consequently, the prophylactic use of echinocandins must be critically questioned regarding the high rate of breakthrough infections, the increased occurrence of fluconazole-resistant pathogens, and the higher mortality rate in non-albicans Candida species. Adherence to the internal prophylaxis algorithms is of immense importance, bearing in mind the high IFI rates in case algorithms are not followed.

Mugaanyi J, Tong J, Lu C, Mao S, Huang J, Lu C. Risk factors for acute rejection in liver transplantation and its impact on the outcomes of recipients. Transpl Immunol 2023; 76:101767. [PMID: 36470573 DOI: 10.1016/j.trim.2022.101767] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2022] [Revised: 10/10/2022] [Accepted: 11/28/2022] [Indexed: 12/03/2022]
Abstract
OBJECTIVE To determine the risk factors for acute rejection in liver transplantation and its impact on the outcomes of the recipients. METHODS Clinicopathological data of 290 patients who underwent liver transplantation from January 2012 to December 2021 at our center were retrospectively evaluated. Patients were grouped into an acute rejection (AR) group and a normal (NM) group based on the confirmed histopathological diagnosis of acute rejection. Univariate and multivariate logistic regression were used to determine the risk factors for acute rejection. RESULTS 244 patients were included in the study. Acute rejection occurred in 27 (11.1%) of the patients. Warm ischemia time (P = 0.137), cold ischemia time (P = 0.064) and chronic liver failure (P = 0.001) were potential risk factors for acute rejection. Chronic liver failure (P < 0.001, OR = 8.22, 95% CI = 2.47-27.32) was the independent risk factor. There was no significant difference in overall survival between recipients with acute rejection and those without it (P = 0.985). The 1-, 3- and 5-year overall survival in the NM group was 98.1%, 85.7% and 78.6% respectively vs 88.9%, 82.5% and 82.5% respectively in the AR group. CONCLUSION Acute rejection does not appear to affect the long-term survival of the recipients. Only chronic liver failure was an independent risk factor for acute rejection. Our findings further illustrate that contradictions still exist on which factors influence acute rejection in liver transplant recipients. SUMMARY Clinicopathological data of 290 liver transplant recipients at our center between January 2012 and December 2021 were retrospectively evaluated to determine the risk factors for acute rejection and its impact on the outcomes of the recipients. 244 patients were included in the analysis. 27 of the 244 experienced acute rejection. Propensity score matching was performed to reduce the confounding effect. Patients were assigned to an acute rejection group (n = 27) and a normal group (n = 54). Chronic liver failure (P < 0.001, OR = 8.22, 95% CI = 2.47-27.32) was the determined to be independent risk factor for acute rejection. Acute rejection did not appear to affect the long-term survival of the recipients and there was no significant difference in overall survival between the patients with acute rejection and those without it.

Abstract
BACKGROUND Personality traits influence clinical outcomes in chronic diseases, but their impact in cirrhosis is unknown. We studied the personality of patients with cirrhosis undergoing liver transplant (LT) evaluation and determined their correlation to clinical outcomes. METHODS A multicenter' prospective study of adult patients undergoing LT evaluation was performed from January 2018 to October 2019. The "Big Five" personality traits of conscientiousness, extraversion, openness, neuroticism, and agreeableness plus agency were assessed with the Midlife Development Inventory Personality Scale and compared with the general population. Frailty was assessed with the Liver Frailty Index. RESULTS Two hundred sixty-three LT candidates were enrolled. Twenty-four percent had hepatitis C virus, 25% nonalcoholic steatohepatitis, and 25% ethyl alcohol (mean model for end-stage liver disease = 15.7). Compared with the general population, LT candidates had higher openness (3.1 versus 2.9; P < 0.001), extraversion (3.2 versus 3.1; P < 0.001), agreeableness (3.5 versus 3.4; P = 0.04), agency (2.9 versus 2.6; P < 0.001), neuroticism (2.2 versus 2.1; P = 0.001), and lower conscientiousness (3.3 versus 3.4; P = 0.007). Patients with higher conscientiousness were more likely to receive an LT (HR = 2.76; P = 0.003). CONCLUSIONS Personality traits in LT candidates differ significantly from the general population, with higher conscientiousness associated with a higher likelihood of receiving a transplant.

Abstract
Pediatric transplant centers are faced with the difficult task of maximizing the benefit of organs donated for transplantation while also ensuring that all patients undergoing transplant evaluation are fairly considered for this life-saving therapy. Children with neurodevelopmental disabilities are a complex patient population that on occasion may face the need for a solid organ transplant. Several concerns exist regarding transplantation in this population, yet standard transplant inclusion and exclusion criteria do not exist. Here we explore important factors regarding organ transplantation for children with neurodevelopmental disorders, including patient outcomes, quality of life considerations, and the fundamental ethical principles underlying this complex medical decision-making.

Abstract
AIM Few data are available regarding the management of anorectal abscess in patients with leukopenia. The aim of this study was to investigate the impact of leukopenia among patients undergoing incision and drainage for anorectal abscess. METHOD A retrospective review of the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database identified patients from 2015 to 2020. Perianal fistulas and supralevator abscesses were excluded. Patients were grouped based on white blood cell (WBC) count: WBC < 4.5 cells/μl, WBC = 4.5-11.0 cells/μl and WBC > 11.0 cells/μl. The 30-day overall complications and outcomes were compared using regression models, accounting for demographics and comorbidities. RESULTS Ten thousand two hundred and forty (70.3% male) patients were identified. Univariate analysis showed that, compared with patients with leukocytosis (WBC > 11.0 cells/μl) and normal WBC count (WBC = 4.5-11.0 cells/μl), patients with leukopenia (WBC <4.5 cells/μl) had higher rates of overall (p < 0.001), pulmonary (p < 0.001) and haematological complications (p < 0.001). They also had higher rates of readmission (p < 0.001), reoperation (p = 0.005), discharge to a care facility (p = 0.003), increased length of hospital stay (p = 0.004) and death (p < 0.001). Multivariable analysis identified leukopenia as an independent risk factor for overall complications [odds ratio (OR) 2.31, 95% CI 1.65-3.24; p < 0.001], pulmonary complications (OR 5.65, 95% CI 1.88-16.97; p = 0.002), haematological complications (OR 4.30, 95% CI 2.94-6.28; p < 0.001), unplanned readmission (OR 2.20, 95% CI 1.43-3.40; p < 0.001), reoperation (OR 1.80, 95% CI 1.10-2.93; p = 0.019) and death (OR 2.77, 95% CI 1.02-7.52; p = 0.046). Discharge to a care facility and length of stay were not significant on multivariable analysis. CONCLUSION Leukopenia is associated with increased risk for pulmonary and haematological complications, readmissions, reoperations, discharge to a care facility and death after incision and drainage for anorectal abscess.

Abstract
With advances in surgical techniques, medical management, and more equitable allocation systems, children who receive a liver transplantation (LT) today can expect remarkable outcomes early after LT. However, beyond 1 year after transplant, attrition rates have not improved. We reviewed two separate eras (Era 1: January 1995-June 2004 vs. Era 2: July 2004-March 2018) of the Society of Pediatric Liver Transplantation registry to explore the evolution and associated factors contributing to late graft loss (LGL) and late mortality (LM). The fraction of long-term pediatric LT recipients surviving after 1 year with their first graft significantly improved (81.5% in Era 1 vs. 85.7% in Era 2; p < 0.0001). This improvement occurred despite significant changes in patient selection toward higher risk populations (p < 0.001) and without notable improvement in perioperative complications such as hepatic artery thrombosis (p = 0.24) and early posttransplant reoperation (p = 0.94) that have historically contributed to poor late-allograft outcomes. Improved outcomes were associated with changes in patient characteristics and perioperative practices, which subsequently impacted both early post-LT complications as well as other sequalae known to contribute to adverse events in long-term pediatric LT recipients. In conclusion, despite significant changes in patient selection toward higher risk populations, and without notable improvement in several perioperative complications known to contribute to poor late-allograft outcomes, significant improvements in LGL and a trend toward improvement in LM was seen in a more contemporary cohort of children receiving an LT.

Abstract
OBJECTIVES Chronic liver disease is often associated with testosterone deficiency. However, testosterone replacement does not improve hepatic function or survival with diseased liver. So far, to our knowledge, testosterone replacement therapy after successful livertransplantforfunctional sarcopenia has not been studied. We had 3 goals: (1) define postoperative functional sarcopenia afterlivertransplant with serum testosterone level; (2) examine the role of short-term testosterone replacement therapy with active in-bed exercise of upper and lower extremity joints; and (3) correlate functional sarcopenia with skeletal muscle index and skeletal muscle density in relation to ascites, pleural effusion subtracted body mass index. MATERIALS AND METHODS We evaluated 16 liver transplant recipients who had been receiving posttransplanttestosterone replacementtherapy with functional sarcopenia. Preoperative and postoperative demographics and laboratory and radiological data were retrieved; body mass index, skeletal muscle index, and skeletal muscle density were calculated. For this retrospective study, institutional review board approval was obtained before the electronic database was reviewed and analyzed. RESULTS Mean testosterone level was 28.3 ng/dL (<5% of expected). Twelve patients received 1 dose, and the remaining 4 patients received >1 dose oftestosterone cypionate, 200 mg. Mean hospital stay was 26 days. Seven patients were discharged home, with the remaining patients to a rehabilitation facility or nursing home. One patient died from a cardiac event, and another patient died from recurrent metastatic malignancy. The 1-year and 5-year actuarial patient and graft survival rates were 93.8% and 87.5%, respectively. Overall, 5 patients were sarcopenic by skeletal muscle index, and 6 patients had poor muscle quality by skeletal muscle density. CONCLUSIONS Testosterone deficiency after liver transplant exists with functional sarcopenia. Two- thirds of such recipients have low skeletal muscle index and/or have low skeletal muscle density. Short- term testosterone replacement therapy with in-bed active exercise provides 5-year patient and graft survival of 87.5%.

Abstract
INTRODUCTION Pediatric liver transplant recipients have demonstrated excellent long-term survival. The purpose of this analysis is to investigate factors associated with 20-year survival to identify areas for improvement in patient care. METHODS Kaplan-Meier with log-rank test as well as univariate and multivariate logistic regression methods were used to retrospectively analyze 4,312 liver transplant recipients under the age of 18 between September 30, 1987 and March 9, 1998. Our primary endpoint was 20-year survival among one-year survival. RESULTS Logistic regression analysis identified recipient age as a significant risk factor, with recipients below 5 years old having a higher 20-year survival rate (p < 0.001). A preoperative primary diagnosis of a metabolic dysfunction was found to be protective compared to other diagnoses (OR 1.64, CI 1.20-2.25). African-American ethnicity (OR 0.71, CI 0.58-0.87) was also found to be a risk factor for mortality. Technical variant allografts (neither living donor nor cadaveric) were not associated with increased or decreased rates of 20-year survival. CONCLUSIONS Our analysis suggests that long-term survival is inversely correlated with recipient age following pediatric liver transplant. If validated with further studies, this conclusion may have profound implications on the timing of pediatric liver transplantation.

Abstract
PURPOSE OF REVIEW Liver transplantation for intrahepatic cholangiocarcinoma (iCCA) has been mired in controversy. High rates of recurrence posttransplant combined with donor organ scarcity resulted in most transplant centers treating iCCA as a contraindication for liver transplantation. RECENT FINDINGS Recent studies have shown that carefully selected patients with unresectable iCCA can have good outcomes after liver transplantation. Better outcomes have been seen in patients with smaller tumors and favorable tumor biology. SUMMARY Because many patients are diagnosed with iCCA at later stages, tumor biology and genetics are useful tools to identify patients who will have excellent overall and recurrence-free survival after liver transplantation. Further larger multicenter prospective studies are needed to identify patients who would benefit from liver transplantation with good outcomes. Additional advances will come through early diagnosis and utilizing a combination of chemotherapy and locoregional modalities as a bridge to transplant. There is also a need to recognize and develop additional neo- and adjuvant therapies for patients whose tumor biology currently precludes their inclusion on the liver transplantation waitlist.

Do Patients with Autoimmune Conditions Have Less Access to Liver Transplantation despite Superior Outcomes? J Pers Med 2022; 12:jpm12071159. [PMID: 35887656 PMCID: PMC9320508 DOI: 10.3390/jpm12071159] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2022] [Revised: 07/13/2022] [Accepted: 07/14/2022] [Indexed: 11/17/2022] Open
Abstract
Orthotopic liver transplantation (OLT) is a lifesaving therapy for patients with irreversible liver damage caused by autoimmune liver diseases (AutoD) including autoimmune hepatitis (AIH), primary biliary cholangitis (PBC), and primary sclerosing cholangitis (PSC). Currently, it is unclear how access to transplantation differs among patients with various etiologies of liver disease. Our aim is to evaluate the likelihood of transplant and the long-term patient and graft survival after OLT for each etiology for transplantation from 2000 to 2021. We conducted a large retrospective study of United Network for Organ Sharing (UNOS) liver transplant patients in five 4-year eras with five cohorts: AutoD (PBC, PSC, AIH cirrhosis), alcohol-related liver disease (ALD), hepatocellular carcinoma (HCC), viral hepatitis, and nonalcoholic steatohepatitis (NASH). We conducted a multivariate analysis for probability of transplant. Intent-to-treat (ITT) analysis was performed to assess the 10-year survival differences for each listing diagnosis while accounting for both waitlist and post-transplant survival. Across all eras, autoimmune conditions had a lower adjusted probability of transplant of 0.92 (0.92, 0.93) compared to ALD 0.97 (0.97, 0.97), HCC 1.08 (1.07, 1.08), viral hepatitis 0.99 (0.99, 0.99), and NASH 0.99 (0.99, 1.00). Patients with AutoD had significantly better post-transplant patient and graft survival than ALD, HCC, viral hepatitis, and NASH in each and across all eras (p-values all < 0.001). Patients with AutoD had superior ITT survival (p-value < 0.001, log rank test). In addition, the waitlist survival for patients with AutoD compared to other listing diagnoses was improved with the exception of ALD, which showed no significant difference (p-value = 0.1056, log rank test). Despite a superior 10-year graft and patient survival in patients transplanted for AutoD, patients with AutoD have a significantly lower probability of receiving a liver transplant compared to those transplanted for HCC, ALD, viral hepatitis, and NASH. Patients with AutoD may benefit from improved liver allocation while maintaining superior waitlist and post-transplant survival. Decreased access in spite of appropriate outcomes for patients poses a significant risk for increased morbidity for patients with AutoD.

Abstract
BACKGROUND Liver transplantation (LTX) has been described as a rescue treatment option in severe, intractable post-hepatectomy liver failure (PHLF), but is not considered to be indicated for this condition by many hepatobiliary and transplant surgeons. In this article we describe the clinical experience of five northern European tertiary centers in using LTX to treat selected patients with severe PHLF. METHODS All patients subjected to LTX due to PHLF at the participating centers were identified from prospective clinical databases. Preoperative variables, surgical outcome (both resection surgery and LTX) and follow-up data were assessed. RESULTS A total of 10 patients treated with LTX due to severe PHLF from September 2008 to May 2020 were identified and included in the study. All patients but one were male and the median age was 70 years (range 49-72). In all patients the indication for liver resection was suspected malignancy, but in six patients post-resection pathology revealed benign or pre-malignant disease. There was no 90-day mortality after LTX. Patients were followed for a median of 49 months (13-153) and eight patients were alive without recurrence at last follow-up. DISCUSSION In selected patients with PHLF LTX can be a life-saving procedure with low short-term risk.

Expansion of Liver Transplantation Criteria for Hepatocellular Carcinoma from Milan to UCSF in Australia and New Zealand and Justification for Metroticket 2.0. Cancers (Basel) 2022; 14:cancers14112777. [PMID: 35681757 PMCID: PMC9179466 DOI: 10.3390/cancers14112777] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2022] [Revised: 05/24/2022] [Accepted: 05/29/2022] [Indexed: 12/12/2022] Open
Abstract
Background: Expansion in liver transplantation (LT) criteria for HCC from Milan to UCSF has not adversely impacted overall survival, prompting further expansion towards Metroticket 2.0 (MT2). In this study, we compared patient survival post-transplant before and after 2007 and long-term outcomes for LT within Milan versus UCSF criteria (to determine the true benefit of the expansion of criteria) and retrospectively validated the MT2 criteria. Methods: Retrospective analysis of ANZLITR (including all patients transplanted for HCC since July 1997). The entire cohort was divided based on criteria used at the time of listing, namely, Milan era (1997−2006) and the UCSF era (2007−July 2015). Results: The overall 5- and 10-year cumulative survival rates for the entire cohort of 691 patients were 78% and 69%, respectively. Patients transplanted in UCSF era had significantly higher 5- and 10-year survival rates than in the Milan era (80% vs. 73% and 72% vs. 65%, respectively; p = 0.016). In the UCSF era, the 5-year survival rate for patients transplanted within Milan criteria was significantly better than those transplanted outside Milan but within UCSF criteria (83% vs. 73%; p < 0.024). Patients transplanted within the MT2 criteria had a significantly better 5- and 10-year survival rate as compared to those outside the criteria (81% vs. 64% and 73% vs. 50%, respectively; p = 0.001). Conclusion: Overall survival following LT for HCC has significantly improved over time despite expanding criteria from Milan to UCSF. Patients fulfilling the MT2 criteria have a survival comparable to the UCSF cohort. Thus, expansion of criteria to MT2 is justifiable.

Abstract
Background Long-term survival after liver transplantation (LT) for hepatocellular cancer (HCC) continues to increase along with the modification of inclusion criteria. This study aimed at identifying risk factors for 5- and 10-year overall and HCC-specific death after LT. Methods A total of 1,854 HCC transplant recipients from 10 European centers during the period 1987-2015 were analyzed. The population was divided in three eras, defined by landmark changes in HCC transplantability indications. Multivariable logistic regression analyses were used to evaluate the significance of independent risk factors for survival. Results Five- and 10-year overall survival (OS) rates were 68.1% and 54.4%, respectively. Two-hundred forty-two patients (13.1%) had HCC recurrence. Five- and 10-year recurrence rates were 16.2% and 20.3%. HCC-related deaths peaked at 2 years after LT (51.1% of all HCC-related deaths) and decreased to a high 30.8% in the interval of 6 to 10 years after LT. The risk factors for 10-year OS were macrovascular invasion (OR = 2.71; P = 0.001), poor grading (OR = 1.56; P = 0.001), HCV status (OR = 1.39; P = 0.001), diameter of the target lesion (OR = 1.09; P = 0.001), AFP slope (OR = 1.63; P = 0.006), and patient age (OR = 0.99; P = 0.01). The risk factor for 10-year HCC-related death were AFP slope (OR = 4.95; P < 0.0001), microvascular (OR = 2.13; P < 0.0001) and macrovascular invasion (OR = 2.32; P = 0.01), poor tumor grading (OR = 1.95; P = 0.001), total number of neo-adjuvant therapies (OR = 1.11; P = 0.001), diameter of the target lesion (OR = 1.11; P = 0.002), and patient age (OR = 0.97; P = 0.001). When analyzing survival rates in function of LT era, a progressive improvement of the results was observed, with patients transplanted during the period 2007-2015 showing 5- and 10-year death rates of 26.8% and 38.9% (vs. 1987-1996, P < 0.0001; vs. 1997-2006, P = 0.005). Conclusions LT generates long-term overall and disease-free survival rates superior to all other oncologic treatments of HCC. The role of LT in the modern treatment of HCC becomes even more valued when the follow-up period reaches at least 10 years. The results of LT continue to improve even when prudently widening the inclusion criteria for transplantation. Despite the incidence of HCC recurrence is highest during the first 5 years post-transplant, one-third of them occur later, indicating the importance of a life-long follow-up of these patients.

Abstract
In living-donor liver transplantation, the safety of the donor is critical. In addition, accurately measuring the liver volume is significant as the amount that can be resected from living donors is limited. In this paper, we propose an automated segmentation and volume estimation method for the liver in computed tomography imaging based on a deep learning-based segmentation network. Our framework was trained using the data of 191 donors, achieved a dice similarity coefficient of 0.789, 0.869, 0.955, and 0.899, respectively, in the segmentation task for the left lobe, right lobe, caudate lobe, and whole liver. Moreover, the R^2 score reached 0.980, 0.996, 0.953, and 0.996 in the volume estimation task. We demonstrate that our approach provides accurate and quantitative liver segmentation results, reducing the error in liver volume estimation. Therefore, we expected to be used as an aid in estimating liver volume from CT volume data for living-donor liver transplantation.

Abstract
OBJECTIVES Liver transplant is the gold standard treatment for end-stage liver failure. Short-term and midterm surveys have been published, but there are few long-term surveys. Here, we report the outcomes of our long-term liver transplant survivors. MATERIALS AND METHODS Since 1988, we have performed 694 liver transplants (366 adult, 328 pediatric), including the first deceased donor transplant in Turkey (December 8, 1988); the first pediatric segmental living related transplant in Turkey, the Middle and Near East, and Europe; the world's first adult segmental living related transplant (April 24, 1990); and the world's first living related donor combined liver-kidney transplant (May 16, 1992). We retrospectively evaluated data from recipients who survived >10 years with normal graft function. RESULTS Of 215 recipients, survival ranges were ≥20 years (n = 13), 15 to 19 years (n = 86), and 10 to 14 years (n = 116); 211 remain alive today with normal liver function. There were 5 retransplants to treat chronic graft rejection, of which 4 recipients are alive with normal graft function after a second liver transplant (15, 20, 22, and 31 years after first transplant). One patient died soon after the second liver transplant (15 years after first transplant). Acute rejection episodes were seen in 72 (34%), and 7 were steroid resistant. There were 48 (22.7%) drug-induced complications. Ten patients had de novo malignancy: 5 lymphoma, 2 squamous cell carcinoma, 1 gastrointestinal stromal tumor, 1 thyroid papillary carcinoma, and 1 multiple myeloma. There were also 31 patients with hepatocellular carcinoma before liver transplant: 13 were beyond Milan criteria, 6 had incidental HCC, and 12 were within Milan. CONCLUSIONS Long-term survival after liver transplant is possible with expert care. Few reports have mentioned long-term surveys; our long-term liver transplant survey is among the largest series in the literature.

Abstract
Orthotopic liver transplantation is the treatment of choice for several otherwise irreversible forms of acute and chronic liver diseases. Early implemented immunosuppressant regimens have had disappointing results with high rejection rates. However, new drugs have reduced the daily immunosuppression requirements, thereby improving graft and patient survival as well as kidney function. Liver rejection is a T-cell-driven immune response and is the active target of immunosuppressive agents. Immunosuppressants can be divided into pharmacological or biological drugs: the gold standard is the calcineurin inhibitors, steroids, mycophenolate mofetil, and mechanistic target of rapamycin inhibitors. Compliance with these agents is essential, although they can increase the risk of infections and neoplastic diseases. In some patients, graft tolerance can be achieved. Graft tolerance is defined as the absence of acute and chronic rejection in a graft, with normal function and histology in an immunosuppression-free, fully immunocompetent host, usually as the final result of a successful attempt at immunosuppression withdrawal. The occurrence of immunosuppressive-related complications has led to new protocols aimed at protecting renal function and preventing de novo cancer and dysmetabolic syndrome. The backbone of immunosuppression remains calcineurin inhibitors in association with other drugs, mainly over the short-term period. To avoid rejection and the side effects on renal dysfunction, de novo cancer, and cardiovascular syndrome, optimal long-term immunosuppressive therapy should be tailored in liver transplant recipients.

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 Recent innovations in the field of liver transplantation have led to a wealth of new treatment regimes, with potential impact on the onset of de novo malignancies (DNM). The aim of this multicenter cohort study was to provide contemporary figures for the cumulative incidences of solid and hematological DNM after liver transplantation. METHODS We designed a retrospective cohort study including patients undergoing LT between 2000 and 2015 in three Italian transplant centers. Cumulative incidence was calculated by Kaplan-Meyer analysis. RESULTS The study included 789 LT patients with a median follow-up of 81 months (IQR: 38-124). The cumulative incidence of non-cutaneous DNM was 6.2% at 5-years, 11.6% at 10-years and 16.3% at 15-years. Post-Transplant Lymphoproliferative Disorders (PTLD) were demonstrated to have a cumulative incidence of 1.0% at 5-years, 1.6% at 10-years and 2.2% at 15-years. Solid Organ Tumors (SOT) demonstrated higher cumulative incidences - 5.3% at 5-years, 10.3% at 10-years and 14.4% at 15-years. The most frequently observed classifications of SOT were lung (rate 1.0% at 5-years, 2.5% at 10-years) and head & neck tumors (rate 1.3% at 5-years, 1.9% at 10-years). CONCLUSIONS Lung tumors and head & neck tumors are the most frequently observed SOT after LT.

Abstract
INTRODUCTION AND OBJECTIVES The success of direct-acting antivirals (DAA) has transformed the management of hepatitis C virus (HCV) infection and has led to the expansion of the deceased donor organ pool for liver transplantation. MATERIAL AND METHODS We present a single center retrospective review of liver transplantations performed on HCV-seronegative recipients from HCV-seropositive organs from 11/2017 to 05/2020. HCV nucleic acid testing (NAT) was performed on HCV-seropositive donors to assess active HCV infection. RESULTS 42 HCV-seronegative recipients underwent a liver transplant from a HCV-seropositive donor, including 21 NAT negative (20 liver, 1 simultaneous liver kidney transplant) and 21 NAT positive liver transplants. Two (9.5%) HCV antibody positive/NAT negative recipients developed HCV viremia and achieved sustained virologic response with DAA therapy. The remaining patients with available data (19 patients) remained polymerase chain reaction (PCR) negative at 6 months. 20 (95%) of HCV antibody positive/NAT positive recipients had a confirmed HCV viremia. 100% of patients with available data (15 patients) achieved SVR. Observed events include 1 mortality and graft loss and equivalent rates of post-transplant complications between NAT positive and NAT negative recipients. CONCLUSIONS HCV-seropositive organs can be safely transplanted into HCV-seronegative patients with minimal complications post-transplant.

Evaluation of a gene expression biomarker to identify operationally tolerant liver transplant recipients: the LITMUS trial. Clin Exp Immunol 2022; 207:123-139. [PMID: 35020854 PMCID: PMC8802178 DOI: 10.1093/cei/uxab011] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2021] [Revised: 10/07/2021] [Accepted: 10/27/2021] [Indexed: 02/06/2023] Open
Abstract
LITMUS was a single-centre, Phase 2a study designed to investigate whether the gene biomarker FGL2/IFNG previously reported for the identification of tolerance in murine models could identify operationally tolerant liver transplant recipients. Multiplex RT-PCR was used to amplify eight immunoregulatory genes in peripheral blood mononuclear cells (PBMC) from 69 adult liver transplant recipients. Patients with PBMC FGL2/IFNG ≥ 1 and a normal liver biopsy underwent immunosuppression (IS) withdrawal. The primary end point was the development of operational tolerance. Secondary end points included correlation of tolerance with allograft gene expression and immune cell markers. Twenty-eight of 69 patients (38%) were positive for the PBMC tolerance biomarker and 23 proceeded to IS withdrawal. Nine of the 23 patients had abnormal baseline liver biopsies and were excluded. Of the 14 patients with normal biopsies, eight (57%) have achieved operational tolerance and are off IS (range 12–57 months). Additional studies revealed that all of the tolerant patients and only one non-tolerant patient had a liver gene ratio of FOXP3/IFNG ≥ 1 prior to IS withdrawal. Increased CD4+ T regulatory T cells were detected both in PBMC and livers of tolerant patients following IS withdrawal. Higher expression of SELE (gene for E-selectin) and lower expression of genes associated with inflammatory responses (GZMB, CIITA, UBD, LSP1, and CXCL9) were observed in the pre-withdrawal liver biopsies of tolerant patients by RNA sequencing. These results suggest that measurement of PBMC FGL2/IFNG may enrich for the identification of operationally tolerant liver transplant patients, especially when combined with intragraft measurement of FOXP3/IFNG. Clinical Trial Registration: ClinicalTrials.gov (LITMUS: NCT02541916).

Abstract
BACKGROUND Nonalcoholic fatty liver disease (NAFLD) is associated with substantial morbidity, mortality, and economic burden. With currently no approved treatment, an effective pharmaceutical intervention for this disease must be both clinically- and cost-effective. METHODS A Markov model was constructed to estimate the clinical outcomes, costs, and quality of life impact of a hypothetical pharmaceutical intervention. Lifetime clinical outcomes, life-years, quality-adjusted life-years (QALYs), costs (2020 $US), incremental cost-effectiveness ratios (ICERs), and economically justifiable prices (EJPs) were quantified. Only patients with fibrosis stage F2-F4 were assumed eligible to initiate pharmaceutical treatment. RESULTS Over a mean life expectancy of approximately 21 years in the simulated cohort, drug treatment reduced liver-related mortality by 6.0% (2.7% absolute reduction). Assuming an annual drug cost of $36,000, total discounted medical costs were $574,238 and $120,312 for drug and usual care, respectively, with discounted QALYs estimated to be 9.452 and 9.272 for the two comparators. This yielded an ICER of $2,517,676/QALY gained. The EJP of the drug at an ICER threshold of $150,000/QALY gained was $2,633, a 93% reduction from a base case. Sensitivity analyses suggest that, without a substantial decrease in the drug price, ICERs would exceed $500,000/QALY gained even with the most favorable efficacy assumptions. CONCLUSIONS For a pharmaceutical intervention to be considered cost-effective in the NAFLD fibrosis population, the substantial clinical benefit will need to be coupled with a modest annual price. Annual drug costs exceeding $12,000 likely will not provide reasonable value, even with favorable efficacy. More work is needed to estimate the cost-effectiveness of lifestyle modifications.

Abstract
Background Liver transplantation (LTx) is the only treatment option for patients with end-stage liver disease. Novel organ preservation techniques such as hypothermic machine perfusion (HMP) or normothermic machine perfusion (NMP) are under investigation in order to improve organ quality from extended criteria donors and donors after circulatory death. The aim of this study was to systematically review the literature reporting LTx outcomes using NMP or HMP compared to static cold storage (SCS). Methods The following data were retrieved: graft primary nonfunction rate, early allograft dysfunction (EAD) rate, biliary complication rate, and 12-month graft and patient survival. A total of 15 studies were included (6 NMP and 9 HMP studies), and meta-analysis was performed only for HMP studies because NMP had considerable differences. Results The systematic review showed the potential of NMP to reduce graft injury and lower the liver graft discard rate. The performed quantitative analyses showed that the use of HMP reduces the rate of EAD (odds ratio [OR] 0.51; 95% confidence interval [CI] 0.34–0.76; p = 0.001; I2 = 0%) and non-anastomotic biliary strictures (OR 0.34; 95% CI 0.17–0.67; p = 0.002; I2 = 0%) compared to SCS. Conclusion Our systematic review and meta-analysis revealed that the use of HMP reduces the rate of EAD and non-anastomotic biliary strictures compared to SCS.

Abstract
Hepatocellular carcinoma (HCC) is one of the most lethal human cancers. Liver transplantation has been an effective approach to treat liver cancer. However, significant numbers of patients with HCC experience cancer recurrence, and the selection of suitable candidates for liver transplant remains a challenge. We developed a model to predict the likelihood of HCC recurrence after liver transplantation based on transcriptome and whole‐exome sequencing analyses. We used a training cohort and a subsequent testing cohort based on liver transplantation performed before or after the first half of 2012. We found that the combination of transcriptome and mutation pathway analyses using a random forest machine learning correctly predicted HCC recurrence in 86.8% of the training set. The same algorithm yielded a correct prediction of HCC recurrence of 76.9% in the testing set. When the cohorts were combined, the prediction rate reached 84.4% in the leave‐one‐out cross‐validation analysis. When the transcriptome analysis was combined with Milan criteria using the k‐top scoring pairs (k‐TSP) method, the testing cohort prediction rate improved to 80.8%, whereas the training cohort and the combined cohort prediction rates were 79% and 84.4%, respectively. Application of the transcriptome/mutation pathways RF model on eight tumor nodules from 3 patients with HCC yielded 8/8 consistency, suggesting a robust prediction despite the heterogeneity of HCC. Conclusion: The genome prediction model may hold promise as an alternative in selecting patients with HCC for liver transplant.

Abstract
BACKGROUND There is limited evidence on the safety of immunotherapy use after liver transplantation and its efficacy in treating post-liver transplant hepatocellular carcinoma (HCC) recurrence.
AIM To assess the safety of immunotherapy after liver transplant and its efficacy in treating post-liver transplant HCC recurrence.
METHODS A literature review was performed to identify patients with prior liver transplantation and subsequent immunotherapy. We reviewed the rejection rate and risk factors of rejection. In patients treated for HCC, the oncological outcomes were evaluated including objective response rate, progression-free survival (PFS), and overall survival (OS).
RESULTS We identified 25 patients from 16 publications and 3 patients from our institutional database (total n = 28). The rejection rate was 32% (n = 9). Early mortality occurred in 21% (n = 6) and was mostly related to acute rejection (18%, n = 5). Patients who developed acute rejection were given immunotherapy earlier after transplantation (median 2.9 years vs 5.3 years, P = 0.02) and their graft biopsies might be more frequently programmed death ligand-1-positive (100% vs 33%, P = 0.053). Their PFS (1.0 ± 0.1 mo vs 3.5 ± 1.1 mo, P = 0.02) and OS (1.0 ± 0.1 mo vs 19.2 ± 5.5 mo, P = 0.001) compared inferiorly to patients without rejection. Among the 19 patients treated for HCC, the rejection rate was 32% (n = 6) and the overall objective response rate was 11%. The median PFS and OS were 2.5 ± 1.0 mo and 7.3 ± 2.7 mo after immunotherapy.
CONCLUSION Rejection risk is the major obstacle to immunotherapy use in liver transplant recipients. Further studies on the potential risk factors of rejection are warranted.

Abstract
INTRODUCTION De Novo malignancy after liver transplantation (LTx) is the second most common cause of death in adult LTx recipients. The current report identifies differences in Standardized Incidence Ratios (SIR) for various non-lymphoid de novo malignancies by comparing and analyzing post LTx SIR for non-lymphoid de novo malignancies. MATERIAL AND METHODS A thorough search of PubMed and Web of Science databases was conducted; 25 publications describing de novo malignancies post-LTx with SIR were identified. RESULTS Overall SIR varied from 1.4 to 11.6 (median 2.4). Oropharyngeal/larynx (OPL), lung, colo-rectal, and kidney malignancies were more prevalent with higher SIR (median = 4.4, 1.9, 2.67, 2.5, respectively). Breast and prostate malignancies were also more prevalent with lower SIR (median = 0.9, 1.0, respectively). Pancreatic, central nervous system (CNS), melanoma, rare cancers and Kaposi's sarcoma were less prevalent (except in Italy and Sweden) but had much higher SIR (median = 2.6, 2.4, 2.02, 22.5 and 53.6, respectively). The overall higher SIR values are related to the age of the recipient, length of follow-up, the grouping of different organ systems, inclusion or exclusion of epidermal non-malacotic skin cancers, lymphoid malignancy, and occurrence of rare malignancies including Kaposi's sarcoma. CONCLUSION OPL, lung, gastrointestinal, kidney, and bladder malignancies were more prevalent with higher SIR. Breast and prostate cancers were more prevalent with lower SIR. Pancreatic, CNS, melanoma, rare cancers and Kaposi's sarcoma were less prevalent with higher SIR. Age of the recipients, length of follow-up, and rare cancer types influence overall SIR values with some global differences.

Abstract
Importance Traditionally, liver transplant (LT) for alcohol-associated liver disease (ALD) requires 6 months of abstinence. Although early LT before 6 months of abstinence has been associated with decreased mortality for decompensated ALD, this practice remains controversial and concentrated at a few centers. Objective To define patient, allograft, and relapse-free survival in early LT for ALD, and to investigate the association between these survival outcomes and early vs standard LT. Design, Setting, and Participants This cohort study analyzed all patients with ALD who underwent their first LT at a single academic referral center between October 1, 2012, and November 13, 2020. Patients with known pretransplant hepatocellular carcinoma, hepatitis B or C, or an alternative cause of liver failure were excluded. Follow-up period was defined as the time from LT to the most recent encounter with a transplant center or death. Exposures The exposure of interest was early LT, which was defined as less than 180 days of pre-LT abstinence. Standard LT was defined as 180 days or more of pre-LT abstinence. Patients were separated into early LT and standard LT by time from abstinence to LT. Main Outcomes and Measures The outcomes were patient, allograft, relapse-free, and hazardous relapse-free survival for patients who underwent early LT or standard LT. These groups were compared by log-rank testing of Kaplan-Meier estimates. Hazardous relapse was defined as binge, at-risk, or frequent drinking. Abstinence was reassessed at the most recent follow-up visit for all patients. Results Of the 163 patients with ALD included in this study, 88 (54%) underwent early LT and 75 (46%) underwent standard LT. This cohort had a mean (SD) age at transplant of 52 (10) years and was predominantly composed of 108 male patients (66%). Recipients of early LT vs standard LT were younger (median [interquartile range (IQR)] age, 49.7 [39.0-54.2] years vs 54.6 [48.7-60.0] years; P < .001) and had a higher median (IQR) Model for End-stage Liver Disease score at listing (35.0 [29.0-39.0] vs 20.0 [13.0-26.0]; P < .001). Both recipients of early LT and standard LT had similar 1-year patient survival (94.1% [95% CI, 86.3%-97.5%] vs 95.9% [95% CI, 87.8%-98.7%]; P = .60), allograft survival (92.7% [95% CI, 84.4%-96.7%] vs 90.5% [95% CI, 81.0%-95.3%]; P = .42), relapse-free survival (80.4% [95% CI, 69.1%-88.0%] vs 83.5% [95% CI, 72.2%-90.6%]; P = .41), and hazardous relapse-free survival (85.8% [95% CI, 75.1%-92.2%] vs 89.6% [95% CI, 79.5%-94.9%]; P = .41). Conclusions and Relevance Adherence to the 6-month rule was not associated with superior patient survival, allograft survival, or relapse-free survival among selected patients. This finding suggests that patients with ALD should not be categorically excluded from LT solely on the basis of 6 months of abstinence, but rather alternative selection criteria should be identified that are based on need and posttransplant outcomes.

Abstract
Historically, individuals with intellectual disability and end-stage organ disease were discriminated against by transplant professionals and often excluded from transplantation waitlists. Despite antidiscrimination legislation, some transplant programs continue to include intellectual disability as a relative, if not an absolute, contraindication to listing for an organ; this is true for both pediatric and adult individuals in end-stage organ disease. This commentary opposes the absolute exclusion of patients with intellectual disability and end-stage organ disease from transplantation waitlists provided that the candidates are expected to gain a predefined minimum benefit threshold of life-years and quality-adjusted-life years. Intellectual disability is one of many factors that should be considered in determining transplant eligibility and each candidate should have an individualized interdisciplinary assessment.

Abstract
Severe acute alcohol-associated hepatitis that is nonresponsive to medical therapy has an extremely high mortality. Liver transplantation is a feasible treatment option and available at certain transplant centers globally. Selection criteria for liver transplantation are not, uniform but there are important key criteria shared across protocols. Of equal importance to the management of liver disease is the treatment of alcohol use disorder. A thorough assessment of candidates involves input from an addiction specialist and psychiatrist. With careful selection practices, graft and patient survival among transplant recipients with severe alcohol-associated hepatitis is similar to other etiologies of chronic liver disease.

Abstract
Patients with acute-on-chronic liver failure (ACLF) have a devastating prognosis and therapeutic options are limited. Granulocyte-colony stimulating factor (G-CSF) mobilizes immune and stem cells and possess immune-modulatory and proregenerative capacities. In this review, we aim to define the current evidence for the treatment with G-CSF in end-stage liver disease. Several smaller clinical trials in patients with different severity grades of end-stage liver disease have shown that G-CSF improves survival and reduces the rate of complications. Adequately powered multicenter European trials could not confirm these beneficial effects. In mouse models of ACLF, G-CSF increased the toll-like receptor (TLR)-mediated inflammatory response which led to an increase in mortality. Adding a TLR4 signaling inhibitor allowed G-CSF to unfold its proregenerative properties in these ACLF models. These data suggest that G-CSF requires a noninflammatory environment to exert its protective properties.

Prognostic Value of Computed Tomographic Coronary Angiography for Long-Term Major Adverse Cardiac Events after Liver Transplantation. J Clin Med 2021; 10:jcm10143132. [PMID: 34300296 PMCID: PMC8303180 DOI: 10.3390/jcm10143132] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2021] [Revised: 07/09/2021] [Accepted: 07/13/2021] [Indexed: 12/26/2022] Open
Abstract
Computed tomographic coronary angiography (CTCA) has prognostic value for early major adverse cardiac events (MACEs) after liver transplantation. However, the association between CTCA and long-term MACEs in liver transplant (LT) recipients remains unknown. We evaluated the association between CTCA and long-term MACEs within 5 years after living donor liver transplantation (LDLT). A total of 628 LDLT recipients who underwent CTCA were analyzed between 2010 and 2012. MACEs were investigated within 5 years after LDLT. The factors associated with long-term MACEs in transplant recipients were evaluated. Only 48 (7.6%) patients developed MACEs. In the Fine and Gray competing risk regression, a coronary artery calcium score (CACS) of >400 combined with obstructive coronary artery disease (CAD) (subdistribution hazard ratio: 5.01, 95% confidence interval: 2.37–10.58, p < 0.001), age (1.05, 1.01–1.10, p = 0.018), diabetes mellitus (2.43, 1.37–4.29, p = 0.002), dyslipidemia (2.45, 1.23–4.70, p = 0.023), and creatinine (1.19, 1.08–1.30, p < 0.001) were independently associated with long-term MACEs. CACS (>400) combined with obstructive CAD may be associated with MACEs within 5 years after LDLT, suggesting the importance of preoperative noninvasive CTCA in LT recipients. The evaluation of coronary artery stenosis on CTCA combined with CACS may have a prognostic value for long-term MACEs in LT recipients.

Abstract
PURPOSE Biliary complications develop at a higher rate in living donor liver transplantation (LDLT) compared with cadaveric liver transplantation. Almost all studies about biliary complications after LDLT were made with the right lobe. The aim of this study was to determine the frequency of biliary complications developing after adult left lobe LDLT and to evaluate the efficacy of the algorithm followed in diagnosis and treatment, particularly percutaneous radiological treatment. METHODS A total of 2185 LDLT operations performed in our center between May 2009 and December 2019 were retrospectively reviewed and patients receiving left lobe LDLT were analyzed regarding biliary complications and treatments. Biliary complications were treated via percutaneous drainage under ultrasound (US) guidance, endoscopic retrograde cholangiopancreatography (ERCP), and percutaneous transhepatic cholangiography (PTC)/ percutaneous transhepatic biliary drainage (PTBD). Patient demographics, ERCP procedures before percutaneous treatment, and percutaneous treatment indications were analyzed. RESULTS A total of 69 adult patients received left lobe LDLT. Biliary complications requiring endoscopic and/or percutaneous treatment developed in 28 patients (40%). Of these patients, 4 had bile leakage (14%), 20 had anastomosis stricture (72%), and 4 had both leakage and anastomosis stricture (14%). External drainage treatment under ultrasound guidance was sufficient for 2 of 4 patients with bile leakage, and these cases were accepted as minor bile leakage (7%). Overall, 26 patients underwent ERCP; of these, 8 were referred for PTC/PTBD because the guidewire and/or balloon-stent could not pass the anastomosis stricture (n=7) and common bile duct cannulation could not be obtained because of duodenal diverticulum (n=1). Diagnostic PTC was performed in 10 patients, 8 were referred after inadequate/failed ERCP procedure and two were referred directly without ERCP. Anastomosis stricture was found in 7 patients and anastomosis stricture and bile leakage in 3. In 7 patients determined to have stricture, balloon dilatation was applied and then biliary drainage was performed. In 3 patients who had leakage and anastomosis stricture, balloon dilatation was applied for stricture; after dilatation, an IEBD catheter was placed through the leakage region in 2 patients, while a covered metallic stent passing through the leakage region was placed in one patient. CONCLUSION Generally, ERCP is the first preferred method in biliary complications of LDLT; however, in cases where a response cannot be obtained by endoscopic treatment or require complex and/or aggressive treatment, percutaneous radiological treatment should be the treatment of choice before surgery in left lobe LDLT.
