Optimal treatment strategy and prognostic analysis of salvage liver transplantation for patients with early hepatocellular carcinoma recurrence after hepatectomy. Hepatol Res 2024; 54:838-850. [PMID: 38451566 DOI: 10.1111/hepr.14033] [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: 10/17/2023] [Revised: 02/11/2024] [Accepted: 02/16/2024] [Indexed: 03/08/2024]
Abstract
AIM We aimed to investigate the prognostic factors for salvage liver transplant in patients with early hepatocellular carcinoma recurrence after hepatectomy. METHODS This retrospective analysis included 53 patients who underwent salvage living-donor liver transplantation between January 2007 and January 2018. There were 24 and 29 patients in the early (recurrence ≤24 months after primary liver resection) and the late recurrence groups, respectively. RESULTS In the multivariate Cox regression model, pre-liver transplant downstaging therapy, early recurrence (ER) after primary liver resection , and recurrence-to-liver-transplant ≥12 months were independent risks to predict recurrent hepatocellular carcinoma recurrence after salvage living-donor liver transplantation. Compared with the late recurrence group, the ER group showed lower disease-free survival rates (p < 0.001); however, the overall survival rates did not differ between the two groups (p = 0.355). The 1-, 3-, and 5-year disease-free survival rates were 83.3%, 70.6%, and 66.2%, and 96.0%, 91.6%, and 91.6% in the early and late recurrence groups, respectively. When stratified by recurrence-to-liver transplant time and pre-liver transplant downstaging therapy in the ER group, disease-free survival and overall survival rates were significantly different. CONCLUSION ER after primary liver resection with advanced tumor status and a longer period of recurrence-to-liver-transplant (≥12 months) have a negative impact on salvage liver transplant. Our findings provide novel recommendations for treatment strategies and eligibility for salvage liver transplant candidates.

Wen TC, Hsieh CE, Hsu YL, Lin KH, Hung YJ, Chen YL. The role of Roux-en-Y hepaticojejunostomy for the management of biliary complications after living donor liver transplantation. BMC Surg 2023; 23:165. [PMID: 37330487 DOI: 10.1186/s12893-023-02052-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2022] [Accepted: 05/23/2023] [Indexed: 06/19/2023] Open
Abstract
INTRODUCTION Post living donor liver transplantation (LDLT) biliary complications can be troublesome over the post-operative course of patients, especially those with recurrent cholangitis or choledocholithiasis. Thus, in this study, we aimed to evaluate the risks and benefits of Roux-en-Y hepaticojejunostomy (RYHJ) performed after LDLT as a last option to deal with post-LDLT biliary complications. METHODS Retrospectively, of the 594 adult LDLTs performed in a single medical center in Changhua, Taiwan from July 2005 to September 2021, 22 patients underwent post-LDLT RYHJ. Indications for RYHJ included choledocholithiasis formation with bile duct stricture, previous intervention failure, and other factors. Restenosis was defined if further intervention was needed to treat biliary complications after RYHJ was performed. Thereafter, patients were categorized into success group (n = 15) and restenosis group (n = 4). RESULTS The overall success rate of RYHJ in the management of post-LDLT biliary complications was 78.9% (15/19). Mean follow-up time was 33.4 months. As per our findings, four patients experienced recurrence after RYHJ (21.2%), and mean recurrence time was 12.5 months. Three cases were recorded as hospital mortality (13.6%). Outcome and risk analysis presented no significant differences between the two groups. A higher risk of recurrence tended to be related to patients with ABO incompatible (ABOi). CONCLUSION RYHJ served well as either a rescue but definite procedure for recurrent biliary complications or a safe and effective solution to biliary complications after LDLT. A higher risk of recurrence tended to be related to patients with ABOi; however, further research would be needed.

Abstract
The dearth of deceased liver donors has created a supply demand gap, necessitating creation of living donor liver transplantation. However, living donor liver transplantation has relied on directed donation, whereby many potential directed donors are rejected based on ABO blood group incompatibility, hepatic size incompatibility, or the need for biliary or arterial reconstruction during transplant surgery. Much like kidney paired exchange, liver paired exchange (LPE) circumvents these incompatibility issues by relying on anonymous, nondirected, or bridge donors that are better anatomical or histological matches for recipients. Although Asia has taken the lead in LPE, the process has only recently been adopted in North America, with the first successful surgery done in the United States in 2019. Our review article sheds light on the process of LPE and the success of LPE in the United States thus far and, additionally, highlights the several logistical and ethical challenges that must be considered as transplant centers adopt and scale up LPE across the United States to address the increased demand for liver allografts.

Determinants of Antibody Response to SARS-CoV-2 Vaccines in Liver Transplant Recipients: The Role of Immunosuppression Reduction. Vaccines (Basel) 2022; 10:vaccines10111827. [PMID: 36366336 PMCID: PMC9692368 DOI: 10.3390/vaccines10111827] [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: 10/07/2022] [Revised: 10/23/2022] [Accepted: 10/25/2022] [Indexed: 11/29/2022] Open
Abstract
Liver transplant recipients on chronic immunosuppression show an attenuated antibody response after SARS-CoV-2 vaccination. Adjusting immunosuppressants during vaccination remains debated. We enrolled 380 liver transplant recipients receiving 2 doses of a protein subunit, mRNA, or a vector vaccine. The patients were informed to temporarily suspend immunosuppression for 2 weeks for both vaccination doses. We measured anti-live-SARS-CoV-2 spike neutralizing antibody levels at 1−2 months after the second vaccination; 83.9% of patients had humoral responses (SARS-CoV-2 NT50 ≥ 9.62 IU/mL) to 2 doses of vaccines. The mRNA (86.7%) and protein subunit vaccines (85%) yielded higher response rates than the vector vaccines (40.9%). Immunosuppression suspension during the two vaccinations yielded a higher response rate (91.5% vs. 57.7%). Only eight patients (2.1%) experienced transaminase level elevation of thrice the normal value (>110 IU/L) after the second vaccination. Most recovered spontaneously after resuming immunosuppression. Multivariate analysis revealed ABO incompatibility, white blood cell count <4000, lymphocyte count <20%, tacrolimus trough level >6.5 ng/mL, and no immunosuppression adjustment as independent risk factors to nonresponse. The mRNA and protein subunit vaccines yielded a higher response rate. Immunosuppression suspension for 2 weeks enhanced the antibody response. ABO incompatibility, leukopenia, lymphopenia, a high tacrolimus trough level, and no immunosuppression adjustment are associated with nonresponse.

Living-Donor Liver Transplantation for Hepatocellular Carcinoma: Impact of the MELD Score and Predictive Value of NLR on Survival. Curr Oncol 2022; 29:3881-3893. [PMID: 35735419 PMCID: PMC9221955 DOI: 10.3390/curroncol29060310] [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: 04/26/2022] [Revised: 05/18/2022] [Accepted: 05/24/2022] [Indexed: 11/17/2022] Open
Abstract
Background: Patients with hepatocellular carcinoma (HCC) tend to be referred for liver transplantation (LT) at an early stage of cirrhosis, with lower pre-LT Model of End-Stage Liver Disease (MELD) scores. We investigated the impact of high MELD scores on post-LT outcomes in patients with HCC and validated the prognostic significance of the neutrophil-to-lymphocyte ratio (NLR). Patients and Method: This retrospective single-center cohort study enrolled 230 patients with HCC who underwent LDLT from 2004−2019 in our institute. We defined a high MELD score as ≥20. Results: The MELD < 20 and MELD ≥ 20 groups comprised 205 and 25 cases, respectively. Although there was no significant difference in disease-free survival between the two groups (p = 0.629), the incidence of septic shock (p = 0.019) was significantly higher in the high MELD group. The one-, three-, and five-year overall survival rates were not significantly different between the two groups (p = 0.056). In univariate analysis, a high pre-LT NLR was associated with poorer survival in the high MELD group (p = 0.029, hazard ratio [HR]: 1.07, 90% confidence interval [CI]: 1.02−1.13). NLR cut-off values of ≥10.7 and <10.7 were predictive of mortality, with an AUC of 0.705 (90% CI: 0.532−0.879). The one-, three-, and five-year post-LT survival rates were significantly higher among the recipients with an NLR < 10.7 than those with an NLR ≥ 10.7 (p = 0.005). Conclusions: Pre-LT MELD score ≥ 20 was associated with a higher risk of developing post-LT septic shock and mortality. The pre-LT serum NLR is a useful predictive factor for clinical outcomes in patients with HCC with high MELD scores.

Abstract
BACKGROUND The acceptance of ABO-incompatible (ABOi) liver grafts will expand the donor pool for a patient in urgent need for a liver transplantation (LT). Here we report our results with emergency ABOi DD (deceased donor) LT using rituximab and antigen specific immunoadsorption. PATIENTS AND METHODS 2009 to 2019 we performed 20 ABOi DD LTs (adults n = 17, children n = 3) for patients in urgent need for a LT. Immunosuppression consisted of rituximab (n = 20) and basiliximab (n = 15) or anti-thymocyte globuline (n = 4), intravenous immunoglobulin (IVIG; n = 6), tacrolimus, prednisolone and mycophenolate mofetil. Fifteen patients were treated with IA (n = 14) or both IA and plasmapheresis (PP; n = 1) pre-transplant and 18 patients were treated with IA (n = 15) or both IA and PP (n = 3) post-transplant. The median pre-transplant MELD- score was 40 (range 18-40). Patient and graft survival and complications were compared to a 1:4 case matched control group of ABO-identical or compatible (ABOid/c) DDLT. RESULTS The 1-, 3- and 5-year patient and graft survival rates were 85, 85 and 78% for the ABOi recipients and not significantly different compared to ABOid/c controls. Only one ABOi patient developed antibody-mediated rejection. CONCLUSION Patient and graft survival after emergency ABOi DDLT using rituximab and immunoadorption was equal to ABOid/DDLT. ABOi DD LT was a successful approach to expand the donor pool for patients in urgent need for a liver graft.

Abstract
Acute liver failure is life-threatening and has to be treated by liver transplantation urgently. When deceased donors or ABO-compatible living donors are not available, ABO-incompatible (ABO-I) living donor liver transplantation (LDLT) becomes the only choice. How to prepare ABO-I LDLT urgently is an unsolved issue. A quick preparation regimen was designed, which was consisted of bortezomib (3.5mg) injection to deplete plasma cells and plasma exchange to achieve isoagglutinin titer ≤ 1: 64 just prior to liver transplantation and followed by rituximab (375mg/m2 ) on post-operative day one to deplete B-cells. Eight patients received this quick preparation regimen to undergo ABO-I LDLT for acute liver failure from 2012 to 2019. They aged between 50 and 60 years. The median MELD score was 39 with a range from 35 to 48. It took 4.75 ± 1.58 days to prepare such an urgent ABO-I LDLT. All the patients had successful liver transplantations, but one patient died of antibody-mediated rejection at post-operative month 6. The 3-month, 6-month, and 1-year graft/patient survival were 100%, 87.5%, and 75%, respectively. In conclusion, this quick preparation regimen can reduce isoagglutinin titers quickly and make timely ABO-I LDLT feasible for acute liver failure. This article is protected by copyright.

Clinical Relevance of Isoagglutinin Rebound in Adult ABO-Incompatible Living Donor Liver Transplantation. J Pers Med 2021; 11:jpm11121300.

Abstract
ABO-incompatible (ABO-I) living donor liver transplantation (LDLT) can be performed successfully. However, anti-ABO isoagglutinin rebound may cause antibody-mediated rejection (AMR) and graft loss. The risk threshold of isoagglutinin rebound is still not defined. 76 ABO-I LDLT recipients were divided into group A (n = 56) with low isoagglutinin titers (<1:256), and group B (n = 20) with high isoagglutinin titers (≥1:256), at initial assessment for liver transplantation. The last 12 patients in group B received a modified desensitization regimen by adding bortezomib to deplete plasma cells. Six (10.7%) patients in group A and 10 (50.0%) patients in group B had postoperative isoagglutinin rebound (p < 0.001). Three patients (5.54%) in group A and two patients (10%) in group B developed clinical AMR (p = 0.602). The cutoff value of postoperative isoagglutinin rebound to cause clinical AMR was ≥1:1024. Among the 12 patients in group B with bortezomib administration, isoagglutinin rebounded up to 1:128 only, and no clinical AMR occurred. In conclusion, the patients with high isoagglutinin titers had a higher rate of postoperative isoagglutinin rebound. Isoagglutinin rebound ≥1:1024 is risky for developing clinical AMR. Adding bortezomib into the desensitization regimen may mitigate isoagglutinin rebound, and avoid clinical AMR.

Abstract
Human cytomegalovirus (CMV) infection has been reported to compromise liver transplantation (LT) outcomes. Recent studies have shown that CMV has a beneficial oncolytic ability. The aim of this study was to investigate the impact of CMV on tumor recurrence in patients with hepatocellular carcinoma (HCC) who underwent liver transplantation (LT). This retrospective study enrolled 280 HCC patients with LT at our institute between January 2005 and January 2016. Their relevant demographic characteristics, pre- and post-LT conditions, and explant histology were collected. A CMV pp65 antigenemia assay was performed weekly following LT to identify CMV infection. A total of 121 patients (43.2%) were CMV antigenemia-positive and 159 patients (56.8%) were negative. A significantly superior five-year recurrence-free survival was observed among CMV antigenemia-positive patients compared with the CMV-negative group (89.2% vs. 79.9%, p = 0.049). There was no significant difference in overall survival between the positive and negative CMV antigenemia groups (70.2% vs. 75.3%, p = 0.255). The major cause of death was HCC recurrence in CMV antigenemia-negative patients (51.3%), whereas more CMV antigenemia-positive patients died due to other bacterial or fungal infections (58.3%). In the multivariate analysis, the independent risk factors for tumor recurrence included positive CMV antigenemia (p = 0.042; odds ratio (OR) = 0.44; 95% confidence interval (CI) = 0.20–0.97), microscopic vascular invasion (p = 0.001; OR = 3.86; 95% confidence interval (CI) = 1.78–8.36), and tumor status beyond the Milan criteria (p = 0.001; OR = 3.69; 95% CI = 1.77–7.71). In conclusion, in addition to the well-known Milan criteria, human CMV is associated with a lower HCC recurrence rate after LT. However, this tumor suppressive property does not lead to prolonged overall survival, especially in severely immunocompromised patients who are vulnerable to other infections.

Can Microscopic Biliary Reconstruction Reduce Biliary Complication Rate in ABO-Incompatible Adult Living Donor Liver Transplantation? Ann Transplant 2021; 26:e931963.

Abstract
Background With the introduction of rituximab, ABO-incompatible (ABOi) living donor liver transplantation (LDLT) has been considered a feasible and safe procedure to overcome the shortage of organ donors. However, higher biliary complication rates remain an unresolved problem in the ABOi group. In our center, biliary anastomosis has been done with microscopic biliary reconstruction (MBR), which effectively reduced the biliary complication rate. The aim of the current study was to investigate whether the microscopic approach reduced anastomotic biliary complications in ABOi LDLT. Material/Methods From March 2006 to December 2018, 30 adult ABOi and 60 ABO-compatible (ABOc) LDLT patients were selected from over 1300 recipients through 1: 2 propensity score-matched cohorts. All patients received MBR during the transplantation. Biliary complications included bile leakage and biliary stricture. Patients with diffuse intrahepatic biliary stricture were excluded from analysis. Results Patient characteristics were similar in the 2 groups. There was no in-hospital mortality in the ABOi LDLT. The long-term survival rates of the ABOi patients were comparable to those of the patients that underwent ABOc LDLT (87.1% vs 87.4%, P=0.964). Those in the ABOi group with anastomotic biliary complications were about 40%, which was higher than in the ABOc patients (40% vs 15%, P=0.01). Conclusions Microscopic biliary reconstruction does not help to reduce the high biliary complication rate in ABOi LDLT. Further investigation and identification regarding other risk factors and precautionary measures involving immunologic and adaptation mechanisms are needed.

[PMID: 34451922 PMCID: PMC8400267 DOI: 10.3390/ph14080825] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2021] [Revised: 08/19/2021] [Accepted: 08/19/2021] [Indexed: 11/17/2022] Open
Abstract
Dexmedetomidine, an α2-adrenergic receptor agonist, is used as an anti-anxiety medication. It exerts a cholinergic effect, thereby reducing the release of tumor necrosis factor alpha (TNF-α). We hypothesized that the use of dexmedetomidine as a sedative agent in transplantation would also protect allografts. We examined our patients who underwent living donor liver transplantation. Subsequently, we generated a series of mouse models to investigate the effect of dexmedetomidine on sedation-based tolerance post transplantation. A total of 49 liver recipients were enrolled in this study, of which 23 (47%) were administered dexmedetomidine through 24 h infusion on postoperative day 1. A trend toward the improvement of hepatocyte injury along with better liver function was observed in the dexmedetomidine-treated group during the first postoperative week. In animal models, dexmedetomidine inhibited the proliferation of CD4+ and CD8+ T cells and TNF-α production in a dose-dependent manner. We used dexmedetomidine to treat skin-transplanted mice and observed a significantly prolonged graft survival in mice that were administered a higher dose of dexmedetomidine. Our results revealed that dexmedetomidine exerts a dual effect of sedation and immunosuppression. This light-sedation approach will not only make patients calmer in the intensive care unit but also protect allografts from injury.

Abstract
Background Patients with a Sequential Organ Failure Assessment (SOFA) score >7 on post-transplant day (POD) 7 have been reported to have a higher risk of short-term mortality after living donor liver transplant (LDLT). We sought to identify factors that were associated with early mortality in this high-risk population. Material/Methods A total of 102 patients with a high SOFA score (>7) on POD 7 were enrolled, of which 72 (70.6%) were assigned to the survivor group, and the other 30 (29.4%) patients were assigned to the non-survivor group according to post-transplant 3-month results. Demographics, clinical data, operative parameters, and individual SOFA component scores were collected. Independent risk factors for 3-month mortality were identified by multivariate logistic regression analysis using backward elimination procedures. Results Of 102 high SOFA score patients, the 3-month mortality rate after LDLT in our study was 29.4%. Four independent risk factors were indicative for early death: graft-to-recipient weight ratio (GRWR) <0.8 (hazard ratio [HR]=3.00; 95% CI=1.05–8.09; P=0.041), longer warm ischemia time (HR=37.84; 95% CI=1.63–880.77; P=0.024), high liver component of the SOFA score, and cardiovascular component of the SOFA score (liver component: HR=10.39; 95% CI=1.77–60.89; P=0.009 and cardiovascular component: HR=13.34; 95% CI=2.22–80.12; P=0.005). Conclusions In conclusion, 3-month mortality among patients with high SOFA score on POD 7 is associated with multiple independent risk factors, including smaller GRWR, longer warm ischemia time, and higher category of liver and cardiovascular component of SOFA score. By recognizing high-risk patients earlier, the LDLT outcomes may be improved by timely intensive therapies.

Abstract
During the past few decades, liver transplant has developed from a high-mortality procedure to an almost routine procedure with good survival outcomes. The development of living donor liver transplant has increased the availability of liver grafts, and the scope of indications for liver transplant has been expanding ever since. The aim of this review is to provide an overview of such an expansion of scope. Various criteria have been proposed to expand the eligibility of patients with hepatocellular carcinoma exceeding the Milan criteria for liver transplant. Furthermore, liver transplant is increasingly performed as a treatment modality for cholangiocarcinoma, neuroendocrine liver metastasis and colorectal liver metastasis. The number of elderly patients receiving liver transplant is on the rise. Combined organ transplantation has also been adopted to treat patients with multiple organ failure. Going forward, further development of preoperative noninvasive predictors in tumor, patient and even donor factors is needed to identify patients at risk of poor outcomes and hence optimize patient management.

Abstract
BACKGROUND To investigate the safety of using ABO incompatible (ABO-i) liver grafts in pediatric patients under our prophylactic strategies. METHODS A total number of 544 pediatric liver transplantations between January 2013 and December 2017 performed in Organ Transplant Center, Tianjin First Central Hospital were included in this study. The recipients were divided into 3 groups based on the compatibility of donor-recipient blood type matching (ABO-identical group, n = 352, ABO-compatible group, n = 121 and ABO-incompatible group, n = 71). Recipient characteristics, perioperative data, postoperative complications and recipient survival rate were compared. The recipient outcomes between living-related and non-living-related ABO-incompatible liver graft recipients were also compared. RESULTS The median follow-up time in three groups were 3.4 (1.8, 6.4) years, 3.2 (1.8, 6.1) years and 2.8 (1.8, 6.2) years, without statistical difference. The cumulative 1-year and 3-year graft survival rate were 94.3% and 94.0% in ABO-id group, 93.1% and 93.1% in ABO-c group and 97.1% and 97.1% in ABO-i group. The cumulative 1-year and 3-year recipient survival rate were 96.1% and 95.5% in ABO-id group, 94.8% and 94.8% in ABO-c group and 97.1% and 97.1% in ABO-i group, respectively. No significant difference was seen among three groups. The recipient characteristics and perioperative data were similar among three groups. The recipients in ABO-i group showed significantly lower incidence of portal vein stenosis. Apart from that, three groups shared equal incidence of other surgical complications and acute rejection. Among ABO-i liver graft recipients, the cumulative 1-year and 3-year recipient survival rate were 98.2% and 98.2% in living donor liver transplant (LDLT) recipients and 92.9% and 92.9% in deceased donor liver transplant (DDLT) recipients, without significant difference. The incidence of hepatic artery thrombosis was significantly higher in DDLT group compared with LDLT group, while the other complications were similar between two groups. CONCLUSION Our data revealed that the application of ABO-i liver grafts in pediatric liver transplantation under rational peri-operative management strategy is a safe measure to increase donor availability for pediatric patients in Chinese population.

Abstract
Objective Cytomegalovirus (CMV) infection has a significant negative impact on liver transplant (LT) recipients. We aimed to evaluate the efficacy of real‐time DNA quantitative polymerase chain reaction (qPCR) in the early detection of CMV and predicting post‐transplant outcomes. Materials and Methods This was a retrospective study that enrolled a total of 49 adult LT recipients between December 2016 and October 2019. Serial CMV qPCR were tested weekly. We used operating characteristic curve analysis to quantify qPCR replication numbers to decide the optimal threshold to predict posttransplant complications and overall survival. Results The optimal cut‐off value of 180 copies/ml (=164 IU/ml) was determined. We had 40 patients in the low qPCR group (<180 copies/ml) and nine patients in the high qPCR group (≥180 copies/ml). Higher qPCR was associated with more severe CMV disease, early allograft dysfunction, major posttransplant complications, longer ICU stays, and lower 2‐year overall survival (OS; all p < .05). In the univariate logistic regression model, persistent DNAemia ≥ 4 weeks after anti‐CMV treatment, coexisted bacterial and/or fungal infection, and high CMV qPCR ≥ 180 copies/ml with p < .100. High CMV qPCR ≥ 180 copies/ml (p = .016; hazard ratio [HR] = 19.5; 95% confidence interval [CI] = 1.73–219.49) remained to be the only independent risk factors for major complication by the multivariate analysis. The overall 2‐year OS rates were 92.5% and 66.7% in the low and the high qPCR group, respectively (p = .030). Conclusion Our findings support evidence that qPCR is effective in detecting CMV infection provides an objective perspective in predicting posttransplant outcomes. High plasma CMV DNA load (defined as CMV qPCR ≥ 180 copies/ml or 164 IU/ml) not only indicates a hazard in developing major posttransplant complications but also associates with prolonged and refractory treatment courses.

Abstract
BACKGROUND ABO-incompatible (ABO-i) living donor liver transplantation (LDLT) is a feasible alternative for donor liver allograft in emergency situations, especially in Asia, where deceased-donor organs remain scarce. The reported outcomes of ABO-i LDLT after optimal desensitization are comparable to those of ABO-compatible LDLT. In this retrospective study, we found improved outcomes after ABO-i LDLT with a low-dose rituximab in combination with double-filtration plasmapheresis (DFPP) and prophylactic antibiotic therapy. MATERIAL AND METHODS Between January 2006 and December 2018, a total of 65 recipients underwent ABO-i LDLT surgeries at our center. The study cohort consisted of 50 recipients (Era III) who underwent ABO-i LDLT using the recently updated desensitization protocol, which included rituximab 200 mg intravenous injection once a week prior to LDLT, 4 sessions of DFPP in all patients, and prophylactic antibiotics for 3 months. RESULTS The 3-year overall survival rate achieved in ABO-i LDLT patients was 72.7% (66.6% for Era I and 33.3% for Era II patients). In the study population, 11 patients developed complications due to infection. Five of these patients (10%) died due to overwhelming sepsis. Four patients (8%) were diagnosed with multiple strictures and diffusely scattered dilatation of intrahepatic bile ducts on computed tomography, without vascular complications. Three of them had evidence of antibody-mediated rejection (AMR). CONCLUSIONS Our experience shows that the ABO-i LDLT protocol of lowered rituximab combined with pre-transplant sessions of plasmapheresis and a quadruple immunosuppressive regimen can be effective in chronic liver failure patients with clinical urgency in the absence of an ABO-compatible donor. Fast-tracking the use of ABO-i LDLT is feasible in patients with an acute liver failure (ALF) and can safely increase the donor liver pool, with an acceptable outcome.

KOREAN JOURNAL OF TRANSPLANTATION 2020; 34:109-113. [PMID: 35769350 PMCID: PMC9186818 DOI: 10.4285/kjt.2020.34.2.109] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2020] [Revised: 04/21/2020] [Accepted: 04/22/2020] [Indexed: 12/18/2022] Open
Abstract
The role of the isoagglutinin (IA) titer in liver transplantation (LT) is still not well defined, but the general belief is that a higher titer may result in a higher risk of rejection in ABO-incompatible living donor LT. To reduce the IA titer by 1:16 or lower, plasmapheresis is usually performed before transplantation. However, there is no established protocol for patients for whom plasmapheresis has failed before reaching the target IA titers. Here, we report the cases of three patients who show high baseline IA titers and have failed plasmapheresis: no-response to plasmapheresis, allergic reaction associated with plasmapheresis, and anaphylactic reaction to platelet transfusion. For various reasons, after several plasmapheresis procedures, IA titers were not effectively reduced. In these patients, splenectomy and intravenous immunoglobulin (0.8 g/kg, from the anhepatic phase to 2 days after transplantation) were carried. The protocol biopsy on postoperative day 7 showed no histologic evidence of meaningful acute rejection. The main aim of this work is to demonstrate that we can apply this protocol to patients who have high baseline IA titers and have failed plasmapheresis. Furthermore, this report is enhanced to promote to the transplant community this approach with this type of recipient.

Abstract
Background The scarcity of deceased donor organ donation has led to increasing utilization of living donor liver transplantation (LDLT), which is an optimal treatment for cirrhosis associated with hepatocellular carcinoma (HCC). The study thus aims to analyze prognostic factors and beneficial effects of LDLT for patients with HCC. Methods All patients who underwent LDLT for HCC were included in this study. A multivariate analysis of patients’ clinicopathologic parameters was performed to determine prognostic factors. Subsequently, the type of LDLT was further analyzed and compared based on the result of multivariate analysis. Results Overall, 36 (11.9%) of 303 patients were identified as having HCC recurrence after LDLT. Salvage LDLT (sLDLT) defined by liver transplantation for those patients with recurrent HCC after primary liver resection (LR) was identified as the major prognostic factor of HCC recurrence following the transplantation (HR=2.49 [1.12–5.54], p=0.025). The HCC recurrence incidence and recurrence-free survival after LDLT were significantly inferior in the salvage group than the other group. The pre-transplantation factors were further evaluated and resulted in only maximum tumour size ≥5 cm at primary LR(HR=10.79 [2.10–55.43], p=0.004) affecting post-transplantation HCC recurrence in those patients who had been performed sLDLT. However, patients receiving salvage LDLT had 5- and 10-year overall survival of 86.7% and 52.9%, respectively, measured from the time of initial HCC diagnosis. Conclusion Overall, LDLT achieves a satisfactory result with low incidence of HCC recurrence based on certain transplantation criteria. Despite the higher incidence of HCC recurrence after sLDLT, it remains a promising strategy to improve long-term outcomes.

Cascade plasmapheresis as a desensitization strategy for patients undergoing ABO incompatible living donor liver transplantation (ABOi LDLT): A single center experience. Transfus Apher Sci 2019; 58:442-446. [PMID: 31311754 DOI: 10.1016/j.transci.2019.04.028] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2019] [Revised: 04/06/2019] [Accepted: 04/28/2019] [Indexed: 11/30/2022]
Abstract
BACKGROUND AND AIM The reduction of antibody titres (AT's) to a safe level is essential pre-requisite for patients awaiting ABO-incompatible liver transplantation (ABOi LT). We report our experience of performing cascade plasmapheresis (CP) on 2 different apheresis platforms (COBE Spectra and Spectra Optia) as a desensitization strategy for patients undergoing ABOi LT in our centre. METHODS This retrospective observational study was conducted on patients who underwent CP included in the desensitization protocol for ABOi LDLT. CP/conventional TPE was performed (daily/alternate day with daily estimation of AT) until a target titre of ≤ 8 was achieved. RESULTS During the study period, 4 patients (mean age 46.7 years; 100% males) underwent desensitization for ABOi LDLT with baseline AT (combined IgM and IgG) ranging from 64 to 512. A total of 15 CP sessions (range 2 - 6) were performed with a median of 3.5 sessions/patient. Desensitization rate was 100%. Only 1 patient underwent conventional TPE in the post-transplant due to rise in AT level to 64 (post-operative day 8). Average post-operative length of stay was 49 days (range 30 - 105). None of the patients experienced any episode of rejection (repeat liver biopsy). On follow up (1 year), 2 patients were alive and doing well, while other 2 patients succumbed during their hospital stay due to sepsis. CONCLUSION In our limited experience, the use of CP was safe and effective desensitization strategy for patients undergoing ABOi LDLT.

Serum Tumor Necrosis Factor-α Is Inversely Associated With the Psoas Muscle Index in Both Male and Female Patients Scheduled for Living Donor Liver Transplantation. Transplant Proc 2019; 51:1874-1879. [PMID: 31262437 DOI: 10.1016/j.transproceed.2019.03.034] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2018] [Revised: 02/09/2019] [Accepted: 03/13/2019] [Indexed: 12/18/2022]
Abstract
BACKGROUND Patients on a waiting list for liver transplantation frequently show core muscle wasting, referred to as sarcopenia, which results in poor prognosis. To date, there has been a lack of research on the association between inflammation mediators, including cytokines, and loss of core muscle mass in cirrhotic patients scheduled for living donor liver transplantation (LDLT). METHODS Cytokines in serum, such as interleukin (IL)-2, IL-6, IL-10, IL-12, IL-17, interferon-γ, and tumor necrosis factor (TNF)-α, were retrospectively investigated in 234 LDLT patients 1 day before surgery. The psoas muscle area was measured using abdominal computed tomography within 1 month before surgery and used to calculate the psoas muscle index (PMI = psoas muscle area/height2). The study population was classified into 2 groups according to the interquartile range of PMI: a non-sarcopenia group (> 25th quartile) and a sarcopenia group (≤ 25th quartile) in each sex. RESULTS In both sexes, IL-10 and TNF-α levels were significantly higher in the sarcopenia group than the non-sarcopenia group. In a univariate analysis, male patients showed that serum IL-10 and TNF-α levels were potentially associated with sarcopenia. Serum TNF-α was independently associated with sarcopenia in a multivariate analysis. In female patients, TNF-α was significantly associated with sarcopenia in both univariate and multivariate analyses. Male patients with a PMI ≤ 25th quartile had significantly higher TNF-α levels than those in other quartile ranges, and female patients with a PMI ≤ 25th quartile had a significantly higher TNF-α level than those with a PMI > 75th quartile. CONCLUSIONS Serum levels of TNF-α are inversely associated with skeletal muscle wasting in both male and female patients scheduled for LDLT.

Abstract
Aim The primary aim of this study is to compare the short- and long-term outcomes between ABO-incompatible (ABOi) adult living donor liver transplantation (ALDLT) with rituximab prophylaxis and ABO-compatible (ABOc) ALDLT. Background The strategy of ABOi liver transplantation (LT) was originated initially to increase the donor pool and to enable liver transplantation in emergency conditions. However, ABOi ALDLT remains a controversial approach in comparison to ABOc ALDLT. Methods PubMed, Embase, and the Cochrane Library study search were accomplished to recognize studies comparing ABOi and ABOc ALDLT. Meta-analyses were conducted based on the evaluation of heterogeneity using a fixed-effect model and a random-effect model to assess the short- and long-term outcomes following ABOi ALDLT with rituximab prophylaxis. Results Nine studies comprising a total of 3,922 patients (ABOi = 671 and ABOc = 3,251) were identified. There was no significant difference between ABOi and ABOc groups for 1-year, 3-year, and 5-year OS and graft survival, respectively. Moreover, 1-year and 3-year OS and DFS were similar between both groups for HCC patients. However, ABOi ALDLT had higher incidences of CMV infection, AMR, overall biliary complications, and biliary stricture than ABOc ALDLT and had other comparable postoperative complications. Conclusion Our meta-analysis included studies comparing ABOi and ABOc ALDLT after the introduction of rituximab in a desensitization protocol for ABOi ALDLT. The results of ABOi ALDLT were comparable with those of ABOc ALDLT. However, biliary complications, CMV infection, and AMR remain a concern in the era of rituximab.

Abstract
ABO-incompatible liver transplantation (ABOi LT) using conventional immunosuppression has been considered a contraindication due to the high risk for antibody-mediated complications potentially resulting in graft loss. However, organ shortage has led to the development of anti-A/B antibody reducing immunosuppressive protocols which have made the outcome after living donor (LD) ABOi LT equivalent to that achieved with LD ABO-compatible (ABOc). The experience of deceased donor (DD) ABOi LT is however still limited. In this article, we discuss the historical background and the results after ABOi LT, in the setting of both LD and DD transplantation. We also discuss the remaining hurdles and future strategies in the breaching of the ABO barrier for LT.

Abstract
BACKGROUND Although, ABO-incompatible (ABOi) liver transplantation is considered a high-risk procedure, using newer and more effective preoperative B cell desensitisation techniques, many transplant centres are routinely performing ABOi living donor liver transplantation (LDLT). METHODS This was a retrospective study of 12 patients (adult:pediatric = 10:2; M:F = 9:3; median age, 45.5 years [range 1 to 56 years]) who underwent ABOi LDLT at a tertiary care centre. RESULTS The median model for end-stage liver disease (MELD)/pediatric end-stage liver disease (PELD) scores were 28 (range 18 to 35) and 30.5 (range 24 to 37), respectively. For desensitisation, we initially used two doses of rituximab and two sessions of plasmapheresis preoperatively. We faced high mortality in the initial seven patients (five deaths) due to overwhelming sepsis from multidrug-resistant (MDR) pathogens. Subsequently, we restricted the rituximab to one dose and performed plasmapheresis only when isoagglutinin titre value was more than 1:64. With this regimen, out of the last five patients, four did well. For the whole cohort, the incidence of antibody-mediated rejection, acute cellular rejection, biliary complications, hepatic artery thrombosis, infection, and 5-year patient survival were 16.7%, 16.7%, 16.7%, 8.3%, 75%, and 40%, respectively. The risk factors for mortality were high MELD score, O blood group, and more intense desensitisation protocol. CONCLUSIONS Careful selection of patients and less intense desensitisation protocol are probably important in improving the outcomes in ABOi LDLT.

Abstract
We present a patient with positive donor-specific antibodies (DSA) and crossmatch of ABO-incompatible (ABOi) combined liver and kidney transplantation (CLKT). Antibody-mediated rejection did not occur and the graft had survived for over one year at the time of writing without infectious complications. A 56-year-old man with positive DSA and positive crossmatch underwent living donor CLKT. The preoperative protocol for ABOi consisted of a single dose of rituximab and total plasma exchange (TPE). The result of anti-B antibody titer for IgG was 1:32. The evaluations of complement-dependent cytotoxicity and flow cytometry cross-match revealed a change from T+/B+ to T-/B+. The patient required adult living donor CLKT. Acute rejection episodes were treated using antithymocyte globulin, and the kidney required 7 days' treatment to recover. No further rejection and infectious episodes have been observed in past 13 months since the transplant. DSA and crossmatches are important for antibody detection and analysis. In the rituximab era, TPE can be used to achieve a successful decrease in antibody titer. In countries with a severe shortage of cadaveric organ donors, it may be possible to select ABOi candidate donors with positive DSA and crossmatch.

Abstract
Kidney paired exchange (KPE) constitutes 12% of all living donor kidney transplantations (LDKTs) in the United States. The success of KPE programs has prompted many in the liver transplant community to consider the possibility of liver paired exchange (LPE). Though the idea seems promising, the application has been limited to a handful of centers in Asia. In this article, we consider the indications, logistical issues, and ethics for establishing a LPE program in the United States with reference to the principles and advances developed from experience with KPE.

Abstract
AIM To evaluate the differences in outcomes between ABO-incompatible (ABO-I) liver transplantation (LT) and ABO-compatible (ABO-C) LT. METHODS A systematic review and meta-analysis were performed by searching eligible articles published before No-vember 28, 2016 on MEDLINE (PubMed), EMBASE, and Cochrane databases. The primary endpoints were graft survival, patient survival, and ABO-I-related complications. RESULTS Twenty-one retrospective observational studies with a total of 8247 patients were included in this meta-analysis. Pooled results of patient survival for ABO-I LT were comparable to those for ABO-C LT. However, ABO-I LT showed a poorer graft survival than ABO-C LT (1-year: OR = 0.66, 95%CI: 0.57-0.76, P < 0.001; 3-year: OR = 0.74, 95% CI 0.64-0.85, P < 0.001; 5-yearr: OR =0.75, 95%CI: 0.66-0.86, P < 0.001). Furthermore, ABO-I LT was associated with more incidences of antibody-mediated rejection (OR = 74.21, 95%CI: 16.32- 337.45, P < 0.001), chronic rejection (OR =2.28, 95%CI: 1.00-5.22, P = 0.05), cytomegalovirus infection (OR = 2.64, 95%CI: 1.63-4.29, P < 0.001), overall biliary complication (OR = 1.52, 95%CI: 1.01-2.28, P = 0.04), and hepatic artery complication (OR = 4.17, 95%CI: 2.26-7.67, P < 0.001) than ABO-C LT. In subgroup analyses, ABO-I LT and ABO-C LT showed a comparable graft survival in pediatric patients and those using rituximab, and ABO-I LT showed an increased acute cellular rejection in cases involving deceased donor grafts. CONCLUSION Although patient survival in ABO-I LT was comparable to that in ABO-C LT, ABO-I LT was inferior to ABO-C LT in graft survival and several complications. Graft survival of ABO-I LT could be comparable to that of ABO-C LT in pediatric patients and those using rituximab.

Abstract
We aimed to investigate the effect of body mass index (BMI) on the overall survival rates and to identify the risk factors associated with adverse outcomes. A total of 381 adult-to-adult living donor liver transplantations performed were retrospectively analyzed. These patients were classified according to the BMI categories established by the World Health Organization: The underweight group (BMI<18.5 kg/m2 ) and the non-underweight group (BMI≥18.5 kg/m2 ). The underweight group had significantly worse outcomes, compared with that of the non-underweight group (5-year overall survival: 45.6% vs 74.6%, P<.001). Underweight patients with CD4/CD8 ratio <1.4 had a significant worse prognosis, compared with those with CD4/CD8 ratio ≥1.4. (The 1-, 3-, and 5-year overall patient survival rates in both groups were 71.0% vs 20%, 58.9% vs 0%, and 53.6% vs 0%, respectively, P=.002.) In the multivariate analysis, only CD4/CD8 ratio <1.4 was an independent poor prognostic factor (hazard ratio=7.063, 95% confidence interval=1.329-37.547, P=.022). CONCLUSIONS Pre-operative CD4/CD8 ratio <1.4 is an independent poor prognostic indicator for underweight patients undergoing liver transplantation. Early intervention in replenishing the nutrient deficit and cautious use of immunosuppressive regimens are essential to prepare this high-risk population for a more successful liver transplantation.

BACKGROUND Despite the technical and medical improvements in the recent years, hepatic artery thrombosis (HAT) remains a devastating complication after living donor liver transplantation (LDLT). We described our surgical techniques and monitoring protocols for hepatic artery reconstruction. We reported one of the lowest incidence rates of HAT in the literature. METHODS Between 2008 and 2015, a total of 325 LDLTs performed at our institute were retrospectively analyzed. Under microscope assistance, all hepatic artery anastomosis were performed in a risk-free and back-wall first manner. We collected donors' and recipients' demographics, operative procedures, and outcome. RESULTS A total of 325 adult LDLTs were enrolled in the study. Of these, 297(91.4%) were right liver graft. The mean diameter of the hepatic arteries of the graft was 1.9 ± 0.3 mm. A single HA anastomosis was performed in 310 patients (95.4%). The 1-, 3-, and 5-year overall patient survival rates were 84.8%, 76.8%, and 75.2%, respectively. Only one (0.3%) episode of HAT was encountered in our series. The patient was treated successfully with nonsurgical management. CONCLUSION Our study showed that the occurrence of HAT is avoidable. Identifying risk factors associated with HAT, meticulous surgical techniques, and careful routine flow monitoring are mandatory to avoid disastrous complications.

Application of CD8+ Cells Count as a Guide of Immunosuppressive Regimen Introduction for Very Sick Patients Undergoing Liver Transplantation. Transplant Proc 2016; 48:3356-3361.

Abstract
BACKGROUND Immunosuppression (IS) protocols should be individualized according to the individual recipient's immunity to minimize adverse effects. The aim of this study was to determine whether preoperative levels of CD8+ T lymphocytes could be used as a guide for the introduction of IS. METHODS Sixteen adult liver transplantations in our institute were retrospectively analyzed. The immunosuppressive agents were temporarily withheld for 8 patients with a lower (<10%) preoperative percentage of CD8+ cells after transplant (classified as group A). In this group, postoperative immunosuppressive agents had never been used until acute rejection was suspected. Another 8 patients receiving classic IS were classified as group B. We collected their demographic features and analyzed the clinical courses. RESULTS The postoperative IS-free period of group A was 5 to 120 days (median, 31 days). Our data showed an inverse correlation between CD8+ levels and the severity of liver disease. Although the IS-free protocol did not present a lower incidence of infection-related events, most of them were effectively treated with antibiotics. The 1-, 3-, and 5-year overall patient survival rates were not different between those with a short-term IS-free period and those with regular IS (87.5% vs 100%, 75% vs 100%, and 62.5% vs 87.5%; P = .468). No patient died of graft failure due to acute rejection. CONCLUSIONS Postoperative immunosuppressive agents can be safely withheld for a period of time to preserve proper immune responses against infections in very sick recipients guided by using the CD8+ levels.

Abstract
For a long time, it was considered medical malpractice to neglect the blood group system during transplantation. Because there are far more patients waiting for organs than organs available, a variety of attempts have been made to transplant AB0-incompatible (AB0i) grafts. Improvements in AB0i graft survival rates have been achieved with immunosuppression regimens and plasma treatment procedures. Nevertheless, some grafts are rejected early after AB0i living donor liver transplantation (LDLT) due to antibody mediated rejection or later biliary complications that affect the quality of life. Therefore, the AB0i LDLT is an option only for emergency situations, and it requires careful planning. This review compares the treatment possibilities and their effect on the patients’ graft outcome from 2010 to the present. We compared 11 transplant center regimens and their outcomes. The best improvement, next to plasma treatment procedures, has been reached with the prophylactic use of rituximab more than one week before AB0i LDLT. Unfortunately, no standardized treatment protocols are available. Each center treats its patients with its own scheme. Nevertheless, the transplant results are homogeneous. Due to refined treatment strategies, AB0i LDLT is a feasible option today and almost free of severe complications.
