Abstract
PURPOSE Acute liver failure is a life-threatening condition for which ABO-incompatible living donor liver transplantation (ABOi-LDLT) is sometimes the only life-saving treatment option. We reviewed a single-center experience of adult ABOi-LDLT treatment for acute liver failure (ALF). METHODS Preoperative treatment, immune indices (B cell marker, anti-donor blood-type antibody), and postoperative outcomes were compared between ALF and non-ALF groups. RESULTS There were 5 and 33 patients in the ALF and non-ALF groups, respectively. The ALF group received higher doses of steroids, underwent more rounds of plasma exchange (PE), and underwent transplantation for ALF with a shorter interval following preoperative rituximab (RTx) administration (median: 2 vs 13 days; P < 0.05) than the non-ALF group. Preoperatively, CD19-positive lymphocytes in the peripheral blood were sufficiently depleted in all of the non-ALF group patients, whereas they were poorly depleted in the ALF group. Postoperatively, neither group suffered anti-donor blood-type antibody titer rebound or antibody-mediated rejection. The ALF group had a comparable 5-year survival rate to the non-ALF group (80.0% vs 77.9%). CONCLUSIONS Despite the delayed preoperative administration of RTx, the ALF group showed an uneventful immunological response and acceptable long-term survival rate. Thus, ABOi-LDLT seems a viable treatment option for ALF.

Fan HL, Hsieh CB, Kuo SM, Chen TW. Liver transplantation with simultaneous splenectomy increases risk of cancer development and mortality in hepatocellular carcinoma patients. World J Gastrointest Surg 2022; 14:930-939. [PMID: 36185566 PMCID: PMC9521478 DOI: 10.4240/wjgs.v14.i9.930] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/13/2022] [Revised: 05/24/2022] [Accepted: 08/25/2022] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND Splenectomy has previously been found to increase the risk of cancer development, including lung, non-melanoma skin cancer, leukemia, lymphoma, Hodgkin’s lymphoma, and ovarian cancer. The risk of cancer development in liver transplantation (LT) with simultaneous splenectomy remains unclear.
AIM To compare hepatocellular carcinoma (HCC) recurrence and de novo malignancy between patients undergoing LT with and without simultaneous splenectomy.
METHODS We retrospectively analyzed the outcomes of 120 patients with HCC within the University of California San Francisco criteria who received LT with (n = 35) and without (n = 85) simultaneous splenectomy in the Tri-Service General Hospital. Univariate and multivariate Cox regression analyses for cancer-free survival and mortality were established. The comparison of the group survival status and group cancer-free status was done by generating Kaplan–Meier survival curves and log-rank tests.
RESULTS The splenectomy group had more hepatitis C virus infection, lower platelet count, higher -fetoprotein level, and longer operating time. Splenectomy and age were both positive independent factors for prediction of cancer development [hazard ratio (HR): 2.560 and 1.057, respectively, P < 0.05]. Splenectomy and hypertension were positive independent factors for prediction of mortality. (HR: 2.791 and 2.813 respectively, P < 0.05). The splenectomy group had a significantly worse cancer-free survival (CFS) and overall survival (OS) curve compared to the non-splenectomy group (5-year CFS rates: 53.4% vs 76.5%, P = 0.003; 5-year OS rate: 68.1 vs 89.3, P = 0.002).
CONCLUSION Our study suggests that simultaneous splenectomy should be avoided as much as possible in HCC patients who have undergone LT.

Abstract
BACKGROUND Paired exchange liver transplantation is an evolving strategy to overcome ABO blood group incompatibility and other barriers such as inadequate graft-to-recipient weight ratio and low remnant liver volume in donors. However, for the transplant team to carry 4 major operations simultaneously is a Herculean effort. We analyzed our experience with liver paired exchange (LPE) program over the past 9 y. METHODS This prospective study included 34 of 2340 (1.45%) living donor liver transplantations performed between May 2012 and April 2021. The reason for LPE was ABO incompatibility in all (n = 34) patients included in the study. After donor reassignment through 2-by-2 paired exchange with directed donors, the ABO matching status changed from A to A (n = 17) and B to B (n = 17), which made all matches ABO-identical. Recipients (R) and donors (D) of each swap pair were prospectively divided into R1/D1 and R2/D2 groups for comparative and survival analyses. RESULTS The recipients (n = 34) had a median age of 45.5 y (11-59 y), and 31 were men. LPEs were performed in 4 operating rooms running simultaneously by 2 independent surgical teams. Donor survival was 100%. Baseline clinical and perioperative parameters, postoperative complications, median intensive care unit/hospital stay, and early deaths were comparable (P > 0.1) between the R1 and R2 groups. The median follow-up period was 27 mo (1-108 mo). The 30-d and 1-y survivals were 88.2% (n = 30) and 85.3% (n = 29), respectively. CONCLUSIONS Our experience suggests that with careful attention to ethical and logistical issues, the LPE program can expand the living donor liver pool and facilitate a greater number of living donor liver transplantations.

Abstract
PURPOSE The purpose of this study was to compare the outcomes of infection between liver transplant patients with and without simultaneous splenectomy. METHODS We retrospectively analyzed the records of 211 patients who underwent liver transplantation in the Tri-Service General Hospital from 2012 to 2017. The frequency of blood cultures obtained after liver transplantation; incidence of bacteremia, pathogens, and complications; and overall survival rates were compared between the groups. RESULTS One hundred thirty-three of 211 patients underwent liver transplantation without simultaneous splenectomy. There were no significant differences in the frequency of blood cultures obtained after liver transplantation (non-splenectomy group and splenectomy group: 63% and 62%, respectively); incidences of bacteremia after liver transplantation (21% and 21%, respectively), repeat bacteremia (39% and 35%, respectively), cytomegalovirus infection (4% and 3%, respectively), herpes infection (6% and 7%, respectively), and fungal infection (3% and 3%, respectively); and overall survival rate between the two groups. However, there was a significant difference in infection-related deaths between the groups. Simultaneous splenectomy and episodes of antibody-related rejection were significant risk factors associated with infection-related death in multivariate analyses. CONCLUSION Although simultaneous splenectomy does not increase the incidence of infection, simultaneous splenectomy definitely carries risks of infection-related mortality in liver transplantation.

Abstract
PURPOSE ABO-incompatible (ABO-i) liver transplantation (LT) is a life-saving method for pediatric patients in emergency situations that has the potential to expand the pool of liver donors. However, the risks of ABO-i compared to ABO-compatible (ABO-c) LT are unclear. To address this clinical uncertainty, we conducted a systematic review and meta-analysis to compare clinical outcomes between ABO-i and ABO-c LT in pediatric patients. METHODS A systematic search for studies comparing outcomes between ABO-i and ABO-c LT was performed in the MEDLINE (PubMed), EMBASE, and Cochrane Library databases through May 2020. Outcomes evaluated included graft survival rate, patient survival rate, rejection, infection, biliary complications, and vascular complications. Quality of evidence was assessed using the Newcastle-Ottawa scale. Pooled odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using RevMan 5.3. RESULTS A total of 12 studies involving 7461 patients were included in the review. Meta-analysis of these studies showed significantly lower 1 year, 3 year, and 5 year graft survival rates for ABO-i vs. ABO-c LT (1 year: OR = 0.46, 95% CI 0.35-0.59, P < 0.00001; 3 years: OR = 0.47, 95% CI 0.36-0.63, P < 0.00001; 5 year: OR = 0.48, 95% CI 0.37-0.63, P < 0.00001) as well as significantly lower 1 year, 3 year, 5 year, and 10 year patient survival rates for ABO-i vs. ABO-c (1 year: OR = 0.34, 95% CI 0.24-0.49, P < 0.00001; 3 years: OR = 0.24, 95% CI 0.14-0.40, P < 0.00001; 5 years: OR = 0.47, 95% CI 0.35-0.64, P < 0.00001; 10 years: OR = 0.59, 95% CI 0.38-0.90, P = 0.02). No significant differences were observed between the groups in incidence of cytomegalovirus infection, acute cellular rejection, acute rejection, biliary complications, or hepatic artery thrombosis. CONCLUSIONS Our systematic review and meta-analysis showed consistently lower patient survival and graft survival in pediatric ABO-i LT compared to ABO-c LT. However, ABO-i LT is still a life-saving emergency option for pediatric patients waiting for a suitable liver source.

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
The number of ABO-incompatible living donor liver transplantations (ABO-I LDLT) has increased owing to the use of preoperative rituximab for immunosuppression. However, controversy remains regarding adequate immunosuppression owing to rejection and infection. Here, we present 5 cases of our ABO-I LDLT experience, emphasizing rejection and infectious complications, retrospectively. The treatment protocol included prophylactic rituximab followed by plasma exchange prior to transplantation, splenectomy, and immunosuppressive and prophylactic antibiotic regimens after transplantation. Four of the 5 patients also received local infusion therapy via the portal vein. Neither hyperacute nor antibody-mediated rejection occurred. All grafts were functioning well at discharge. Rehospitalization was required for 2 patients due to severe infection within 6 months of transplantation. Invasive aspergillosis was successfully treated in 1 patient, but the other patient died from severe sepsis with overwhelming postsplenectomy infection syndrome. Our results confirm that, although improved immunosuppressive therapy markedly reduces rejection in ABO-I LDLT, it is also associated with an increased risk of various life-threatening infections.

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
Liver transplantation (LT) is one of the most effective treatments for end-stage liver disease caused by related risk factors when liver resection is contraindicated. Additionally, despite the decrease in the prevalence of hepatitis B virus (HBV) over the past two decades, the absolute number of HBsAg-positive people has increased, leading to an increase in HBV-related liver cirrhosis and hepatocellular carcinoma. Consequently, a large demand exists for LT. While the wait time for patients on the donor list is, to some degree, shorter due to the development of living donor liver transplantation (LDLT), there is still a shortage of liver grafts. Furthermore, recipients often suffer from emergent conditions, such as liver dysfunction or even hepatic encephalopathy, which can lead to a limited choice in grafts. To expand the pool of available liver grafts, one option is the use of organs that were previously considered “unusable” by many, which are often labeled “marginal” organs. Many previous studies have reported on the possibilities of using marginal grafts in orthotopic LT; however, there is still a lack of discussion on this topic, especially regarding the feasibility of using marginal grafts in LDLT. Therefore, the present review aimed to summarize the feasibility of using marginal liver grafts for LDLT and discuss the possibility of expanding the application of these grafts.

Abstract
Liver transplantation has become the best way to cure patients with end-stage liver disease. Due to the shortage of donor organs worldwide and being unable to obtain matched donor liver, most patients with severe hepatic failure lose the chance of operation or even die. As a result, ABO incompatible (ABO-I) liver transplantation has become a choice to save the endangered life. However, compared with ABO compatible liver transplantation, ABO-I liver transplantation is more prone to cause severe antibody mediated rejection (AMR), biliary complications, infection, thrombotic microangiopathy, and acute kidney injury. Consequently, its clinical application is limited. In recent years, with the progress of AMR prevention strategies such as immunoabsorption, plasmapheresis, rituximab, splenectomy, intravenous immunoglobulin, and graft perfusion, the clinical efficacy of ABO-I liver transplantation has been significantly improved, although it still faces the challenge of how to prevent and control AMR and postoperative complications.

Abstract
INTRODUCTION Living donor liver transplantation (LDLT) using ABO-incompatible (ABOi) graft for acute liver failure (ALF) is a developing treatment modality. METHODS We reviewed the changes in our treatment strategies in applying ABOi LDLT for FH over our fourteen years of experience. RESULTS Five patients with ALF received LDLT in adults using ABOi grafts, with different but gradually renewed protocols. The etiologies for acute liver failure included autoimmune hepatitis (n=3) and unknown (n=2). The desensitization protocol for ABOi barrier included Case #1; local infusion (portal vein)+plasma exchange (PE), Case #2; local infusion (hepatic artery)+rituximab+PE, Case #3 and #4; rituximab+PE, and Case #5; rituximab+PE under high-flow continuous hemodiafiltration. Local infusion was abandoned since Case #3, because Case #1 had portal vein thrombosis resulting in graft necrosis and Case #2 had hepatic artery dissection. The patients (Case #2 and #3), who received rituximab within 7 days before LDLT, experienced antibody-mediated rejection. Thus, the most recent protocol for ABOi-LDLT is that rituximab is given 2 weeks before LDLT, followed by high-flow continuous hemodiafiltration to obstacle hepatic encephalopathy until LDLT. The four patients except Case #1 are doing well with good graft function over 3.8±3.7 years. CONCLUSION Rituximab-based ABOi-LDLT, most-recently under high-flow hemodiafiltration for treating encephalopathy, is a feasible option for applying LDLT for ALF.

Abstract
BACKGROUND The use of ABO incompatible (ABOi) graft in living donor liver transplantation (LDLT) has not been an established procedure worldwide. METHODS Four hundred and eight adult LDLTs, using ABOi (n=19) and non-ABOi (n=389) grafts, were performed as a single center experience. RESULTS In ABOi-LDLT group (n=19), median isoagglutinin titer before plasma exchange (PE) at LDLT and after LDLT (max) was ×256, ×32 and ×32, respectively. Rituximab was given at 21.8±6.1 days before LDLT and PE was performed 3.7±1.6 times. Although ABOi-LDLTs had increased rate of splenectomy (89.4% vs. 44.7%, P<0.001) and lower portal venous pressure (PVP) at the end of surgery (13.8±1.1 vs. 16.9±0.2 mmHg, P=0.003), other operative factors including graft ischemic time, operative time and blood loss were not different between the groups. Although ABOi-LDLTs had increased incidence of cytomegalovirus infection (52.6% vs. 22.9%, P=0.007), other post-transplant complications including bacterial sepsis and acute rejection were not different between the groups. The 5-year graft survival rate was 87.9% in ABOi-LDLTs and 80.3% in non-ABOi-LDLTs (P=0.373). CONCLUSIONS ABOi-LDLT could be safely performed, especially under rituximab-based protocol.

Abstract
The objective of this study was to evaluate the results of adult ABO-incompatible living donor liver transplantation (LDLT).ABO-incompatible LDLT is an aggressive treatment that crosses the blood-typing barrier for saving lives from liver diseases. Although graft and patient survival have been improved recently by various treatments, the results of adult ABO-incompatible LDLT require further evaluation.Two regimens were designed based on isoagglutinin IgG and IgM titers and the time course of immunological reactions at this institute. When isoagglutinin IgG and IgM titers were ≤64, liver transplantation was directly performed and rituximab (375 mg/m) was administrated on postoperative day 1 (regimen I). When isoagglutinin titers were >64, rituximab (375 mg/m) was administered preoperatively with or without plasmapheresis and boosted on postoperative day 1 (regimen II). Immunosuppression was achieved by administration of mycophenolate mofetil, tacrolimus, and steroids.Forty-six adult ABO-incompatible and 340 ABO-compatible LDLTs were performed from 2006 to 2013. The Model for End-Stage Liver Disease scores for ABO-incompatible recipients ranged from 7 to 40, with a median of 14. The graft-to-recipient weight ratio ranged from 0.61% to 1.61% with a median of 0.91%. The 1-, 3-, and 5-year survival rates were 81.7%, 75.7%, and 71.0%, respectively, for ABO-incompatible LDLT recipients, compared to 81.0%, 75.2%, and 71.5% for ABO-C recipients (P = 0.912). The biliary complication rate was higher in ABO-incompatible LDLT recipients than in the ABO-compatible recipients (50.0% vs 29.7%, P = 0.009).In the rituximab era, the blood type barrier can be crossed to achieve adult ABO-incompatible LDLT with survival rates comparable to those of ABO-compatible LDLT, but with more biliary complications.

Abstract
Previous studies have demonstrated the safety of ABO-incompatible pediatric LDLT using preoperative plasmapheresis and rituximab; however, no reports have described the timing and dosage of rituximab administration for pediatric LDLT. This study aimed to describe a safe and effective dosage and timing of rituximab for patients undergoing pediatric ABO-incompatible LDLT based on the experience of our single center. A total of 192 LDLTs in 187 patients were examined. These cases included 29 ABO-incompatible LDLTs in 28 patients. Rituximab was used beginning in January 2004 in recipients older than two yr of age (first period: 375 mg/m(2) in two cases; second period: 50 mg/m(2) in two cases; and 200 mg/m(2) in eight cases). Two patients who received 375 mg/m(2) rituximab died of Pneumocystis carinii pneumonia and hemophagocytic syndrome. One patient who received 50 mg/m(2) rituximab required retransplantation as a consequence of antibody-mediated complications. All eight patients administered 200 mg/m(2) survived, and the mean CD20(+) lymphocyte count was 0.1% at the time of LDLT. In the preoperative management of patients undergoing pediatric ABO-incompatible LDLT, the administration of 200 mg/m(2) rituximab three wk prior to LDLT was safe and effective.

Abstract
BACKGROUND Graft local infusion and splenectomy in ABO-incompatible (ABO-I) living donor liver transplantation (LDLT) are associated with high rates of operative complications. METHODS Consecutive ABO-I LDLT patients treated at the National Cancer Centre between January 2012 and February 2013 were identified. The protocol for ABO-I LDLT at the study centre included the administration of rituximab (300 mg/m(2)) at 2 weeks preoperatively, followed by plasma exchanges (target isoagglutinin titre: ≤ 1:8), basiliximab (20 mg on the day of surgery and on postoperative day 4), and i.v. immunoglobulin (0.8 g/kg on postoperative days 1 and 4) without graft local infusion or splenectomy. RESULTS Fifteen patients (11 men and four women) who underwent transplantation for liver cirrhosis (n = 3) or hepatocellular carcinoma (n = 12) were identified. These included 13 patients with hepatitis B virus infection, one with hepatitis C virus infection and one with alcoholic cirrhosis. The mean age, mean Model for End-stage Liver Disease (MELD) score and mean graft-to-recipient weight ratio (GRWR) of these patients was 51.8 years, 11.5 and 0.84, respectively. The median isoagglutinin titre before plasma exchange was 1:32 (range: 1:4 to 1:256). There were no hyperacute or antibody-mediated rejections. No bacterial or fungal infections were observed. Complications included herpes zoster viral infection in one patient, postoperative bleeding in one patient and extrahepatic biliary stricture in three patients. CONCLUSIONS This simplified ABO-I LDLT protocol showed good graft outcomes without immunologic failure or serious infections.

Abstract
BACKGROUND The established procedure for ABO-incompatible liver transplantation (ABO-I LT) was too complicated to be used in case of emergency. We developed a protocol consisting of rituximab and intravenous immunoglobulin (IVIG) for ABO-I LT in patients with acute liver failure (ALF). METHODS The data from 101 patients who had undergone liver transplantation (LT) for ALF were retrospectively analyzed. The patients were divided into two groups: ABO-compatible liver transplantation group (ABO-C LT, n=66) and ABO-I LT group (n=35). All the patients in the ABO-I LT group received a single dose of rituximab (375 mg/m2) and IVIG (0.4 g/kg per day) at the beginning of the operation. IVIG was administered for 10 consecutive days after LT. Plasma exchange, splenectomy and graft local infusion were omitted in the protocol. Quadruple immunosuppressive therapy including basiliximab, corticosteroids, tacrolimus and mycophenolatemofetil was used to reinforce immunosuppression. RESULTS The 3-year cumulative patient survival rates in the ABO-I LT and ABO-C LT groups were 83.1% and 86.3%, respectively (P>0.05), and the graft survival rates were 80.0% and 86.3%, respectively (P>0.05). Two patients (5.7%) suffered from antibody-mediated rejection in the ABO-I LT group. Other complications such as acute cellular rejection, biliary complication and infection displayed no significant differences between the two groups. CONCLUSIONS The simplified treatment consisting of rituximab and IVIG prevented antibody-mediated rejection for LT of blood-type incompatible patients. With this treatment, the patients did not need plasma exchange, splenectomy and graft local infusion. This treatment was safe and efficient for LT of the patients with ALF.

Abstract
ABO-incompatibility is a major obstacle to expanding exiguous donor pools in adult liver transplantation, especially in countries where grafts from deceased donors are uncommon. We present our preliminary results of ABO-incompatible (ABO-I) adult living donor liver transplantation (LDLT) using a new, simple protocol. Seven consecutive cases of ABO-I LDLT were managed by the same protocol including pre-operative administration of a single dose of rituximab (375 mg/m(2) ) followed by three to five sessions of plasma exchange before LDLT without portal infusion therapy. The triple immunosuppression protocol consisted of tacrolimus, mycophenolate mofetil and steroids, with mycophenolate mofetil starting seven d before LDLT. Splenectomy was performed for all cases. All patients are alive (100% survival) with a mean follow-up of 852 d (715-990 d). Neither antibody-mediated nor hyperacute rejection were encountered. There was only one episode of mild acute cellular rejection, for which steroid augmentation was effective. The median preformed isoagglutinin antibody titer before plasma exchange was 256, while the median antibody titer immediately before LDLT was 16. In conclusion, adult ABO-I LDLT results were excellent - comparable or even superior to those of ABO-compatible LDLT. ABO-I adult LDLT has now become a more applicable modality without the need for an appropriate donor.

Abstract
BACKGROUND Whether splenectomy can be performed simultaneously during liver transplantation in patients with end-stage liver diseases complicated by hypersplenism remains controversial. This study aimed to compare the impact of simultaneous splenectomy on high- and low-risk liver transplant patients with end-stage liver diseases and severe hypersplenism. METHODS Forty-two patients with end-stage liver diseases complicated by severe hypersplenism who had undergone orthotopic liver transplantation were enrolled in this study. Splenectomy was performed in 19 of the patients. The 42 patients were grouped according to the risk of liver diseases and operations they received. Patients were considered to be at high-risk if they had at least one of the following conditions: preoperative prothrombin time >5 seconds, portal vein thrombosis, and severe perisplenitis. High-risk patients who had undergone splenectomy were classified into group A, whereas high-risk patients who had not undergone splenectomy were classified into group B. Low-risk patients who had undergone splenectomy were classified into group C, and low-risk patients who had spleen preservation were classified into group D. Operative time, intraoperative blood loss, postoperative bleeding, pulmonary infection, perioperative mortality, and postoperative platelet recovery were analyzed. RESULTS Operative time and intraoperative blood loss were greater in group A than in groups B-D (P<0.01), but there was no significant difference between groups C and D (P>0.05). In group A, 3 patients had postoperative bleeding, 5 had pulmonary infection, and 2 had perioperative mortality, which was higher than any other group, but postoperative bleeding, pulmonary infection, and perioperative mortality were similar to those in groups C and D. In patients undergoing simultaneous splenectomy, platelet counts recovered within 6 months after surgery. Thrombocytopenia was sustained in 3 of the 23 patients who did not undergo simultaneous splenectomy. CONCLUSION Splenectomy should be avoided during orthotopic liver transplantation in high-risk patients, but this procedure does not increase the operative risk in low-risk patients and may be a valuable method to ensure good postoperative platelet recovery.

Abstract
Anti-A/B antibody removal from blood in the peritransplantation period facilitates ABO-incompatible transplantation and significantly increases the donor pool. We have been developing an anti-A/B immunoadsorption device (BSAF), compatible with whole blood perfusion. The BSAF is based on integrated microfiltration hollow fibers with antibody capturing beads uniformly distributed within the fiber interstitial space. In this study we fabricated BSAF prototypes, appropriately scaled down from a conceptual clinical scale device. We then, for the first time, measured the time course of anti-A capture from blood samples recirculating through the scaled down BSAF devices. We observed a significant reduction in IgM (96% ± 5%, n = 5, p < 0.001), and IgG (81% ± 18%, n = 5, p < 0.05) anti-A antibody titers within 2 h. We did not observe a significant change between the initial and final values of hematocrit, total plasma protein concentration, plasma free hemoglobin concentration, and anti-B antibody titer over five experiments. In conclusion we showed that the BSAF modules selectively removed anti-A antibodies from blood in a simple one step process, without requiring a separate plasmapheresis unit.

Abstract
BACKGROUND AND OBJECTIVES Rituximab and intravenous Ig (IVIG) are commonly used for desensitization of HLA and blood group-incompatible (ABOi) transplants. However, serious infections have been noted in association with rituximab administration. In this study, we retrospectively compared infectious outcomes in those who received rituximab plus IVIG for HLA or ABOi transplants (RIT group) with a group of nonsensitized, ABO-compatible transplant recipients (non-RIT group). DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Patients undergoing kidney transplantation at Cedars-Sinai Medical Center were included in the analysis. A total of 361 patients were identified. All received antimicrobial prophylaxis and viral surveillance. The primary outcome was infection. RESULTS Overall patient survival was 97 and 96%, and graft survival was 91 and 89% in the RIT and non-RIT groups, respectively, after an average follow-up of 18 months. There were equal rates of bacterial (34.7% versus 39.1%), viral (21.8% versus 25.1%), fungal (5.9% versus 5.2%), and serious infections (22.9% versus 25.5%) in the RIT and non-RIT groups respectively. Urinary tract infection was the most common infection, accounting for 50% of all bacterial infections. Cytomegalovirus viremia was nonsignificantly more common in the nonrituximab-treated group (15.2% versus 10%), whereas BK viremia was marginally more frequent in the rituximab-treated group (10.6% versus 5.8%). There were no graft losses caused by BK-associated nephropathy. There were two deaths in each group related to infection (1%). CONCLUSION Rituximab does not increase infection risk when used with intravenous Ig for desensitization.

Abstract
BACKGROUND Preformed anti-ABO antibodies are primarily responsible for antibody-mediated rejection (AMR) after ABO-incompatible (ABO-I) liver transplantation (LT) resulting in lethal hepatic necrosis and biliary complications. Splenectomy, an integral part of protocol for ABO-I LT, decreases anti-ABO antibodies. With the preoperative rituximab prophylaxis, role of the splenectomy for ABO-I LT is now under debate. We investigated the necessity of splenectomy by retrospective analyses of the short-term anti-ABO antibody response and long-term outcomes of ABO-I LT. METHODS Thirty-seven ABO-I LTs performed from May 2006 through July 2009, at Kyoto University Hospital, Kyoto, Japan, were retrospectively analyzed. Twenty-seven patients who underwent splenectomy (splenectomy group) received 329.6 ± 35.8 mg rituximab 17.7 ± 11.9 days before living donor LT. Ten patients without splenectomy (nonsplenectomy group) received 320.0 ± 10.3 mg rituximab 26.6 ± 21.3 days before transplantation. All patients received a posttransplant hepatic artery infusion with prostaglandin E1 and methylprednisolone. Perioperative anti-ABO immunoglobulin M and immunoglobulin G antibody titers, rejections, biliary complications, infections, and survival results were compared. RESULTS Preoperative rituximab with plasma exchange effectively reduced anti-ABO antibodies in both patient groups at the time of LT. There was no statistically significant difference observed in anti-ABO immunoglobulin M and immunoglobulin G antibody titers between the "splenectomy" and "nonsplenectomy" groups during the initial 8 weeks. The clinical outcomes, including AMR, biliary complications, infections, and survival, were similar in both the groups. CONCLUSIONS Preoperative rituximab effectively decreased the anti-ABO antibodies sufficiently to prevent the AMR irrespective of splenectomy. Splenectomy does not offer any immunological benefit in ABO-I LT with preoperative rituximab.

Abstract
We present a case of successful living donor liver transplantation (LDLT) for liver cirrhosis caused by hepatitis B virus with severe autoimmune hemolytic anemia (AIHA) using an ABO-incompatible (ABOi) graft. The patient was a 47-year-old woman who had a history of ruptured esophageal varices, accumulation of intractable ascites, frequent hepatic encephalopathy and severe anemia, with a hemoglobin value of approximately 3 g/dL due to AIHA. We treated the patient by LDLT using an ABOi liver graft. The treatment strategy included anti-CD20 antibody, plasma exchange and transfusion before LDLT. The patient's anemia improved after surgery; she required only 2 units of irradiated red blood cell concentrates-leukocytes reduced. The patient was discharged from the hospital on postoperative day 35. Two years after surgery, the patient still shows normal hepatic and hematological findings. The immunomodulation protocol for ABOi LDLT was effective not only to avoid humoral reactions associated with ABOi LDLT, but also those associated with AIHA.

Abstract
ABO incompatibility is the most common cause of donor rejection during the initial screening of adult patients with end-stage liver disease for living donor liver transplantation (LDLT). A paired donor exchange program was initiated to cope with this problem without ABO-incompatible LDLT. We present our results from the first 6 years of this exchange adult LDLT program. Between July 2003 and June 2009, 1351 adult LDLT procedures, including 16 donor exchanges and 7 ABO-incompatible LDLT procedures, were performed at our institution. Initial donor-recipient ABO incompatibilities included 6 A to B incompatibilities, 6 B to A incompatibilities, 1 A to O incompatibility, 1 A+O (dual graft) to B incompatibility, 1 O to AB incompatibility, and 1 O to A incompatibility. Fourteen matches (87.5%) were ABO-incompatible, but 2 (12.5%) were initially ABO-compatible. All ABO-incompatible donors were directly related to their recipients, but 2 compatible donors were each undirected and unrelated directed. After donor reassignment through paired exchange (n = 7) or domino pairing (n = 1), the donor-recipient ABO status changed to A to A in 6, B to B in 6, O to O in 1, A to AB in 1, A+O to A in 1, and O to B in 1, and this made all matches ABO-identical (n = 13) or ABO-compatible (n = 3). Two pairs of LDLT operations were performed simultaneously on an elective basis in 12 and on an emergency basis in 4. All donors recovered uneventfully. Fifteen of the 16 recipients survived, but 1 died after 54 days. In conclusion, an exchange donor program for adult LDLT appears to be a feasible modality for overcoming donor-recipient ABO incompatibility.

Abstract
A 47-year-old Japanese man was transferred to our hospital because of acute-on-chronic hepatitis B virus infection. On admission, he was suffering from sepsis due to a catheter infection and respiratory failure caused by pulmonary edema and pneumonia, but, as a result of preoperative intensive care, we avoided septic shock. ABO-incompatible liver transplantation (ABO-I-LT) was performed. In accordance with our ABO-I-LT protocol, we administered, rituximab and performed plasma exchange, splenectomy as well as hepatic artery infusion. The patient was discharged 80 days after living donor transplantation (LDLT). However, 136 days after LDLT, he experienced recurrent respiratory failure due to severe pneumonia. At that time, the CD19(+) B-cell count in the peripheral blood flow remained below 1%. We suspected a mixed infection involving Streptococcus pneumonia, Pneumocystis carinii, and fungus. The cause of the complication was overwhelming postsplenectomy infection (OPSI). We started administration of sulfamethoxazole and trimethoprim, ciprofloxacin hydrochloride, and micafungin sodium therapy as well as gamma-globulin. Oxygenation improved gradually; the patient was discharged at 41 days after re-admission. Although this patient survived the OPSI, it was clear that some aspects of the ABO-I-LT protocol should also be altered.

Rituximab, IVIG, and plasma exchange without graft local infusion treatment: a new protocol in ABO incompatible living donor liver transplantation. Transplantation 2009; 88:303-7.

Abstract
BACKGROUND Although graft local infusion (GLI) treatment via the portal vein or the hepatic artery has been the pivotal strategy in ABO incompatible (ABOi) living donor liver transplantation (LDLT) in Japan, the procedure is associated with a high rate of catheter-associated complications. METHODS A new ABOi-LDLT protocol has been implemented using rituximab, intravenous immune globulin (IVIG), plasma exchange (PE), and splenectomy, without using GLI, on four patients, since 2007. Three other patients, treated before 2007, received GLI. RESULTS Three of the four patients with liver cirrhosis received rituximab over 3 weeks before LDLT, followed by PEs and post-LDLT IVIG, resulting in no rebound elevation of the isoagglutinin titers. The remaining patient, with fulminant hepatitis, received rituximab 3 days before the LDLT, resulting in antibody-mediated rejection, successfully treated by IVIG and PE. All four patients that were treated with the new protocol are alive, 26, 8, 6, and 5 months after ABOi-LDLT with normal liver function. Two of the three other patients with GLI, before 2007, had catheter-associated complications, including one graft loss. CONCLUSION The new ABOi-LDLT protocol using rituximab, IVIG, and PE, without the use of GLI, therefore seems to be a safe and an effective treatment modality.

Abstract
The optimal management in living donor liver transplantation using an ABO incompatible donor with a high isoagglutinin titer is still uncertain. Our patient was a 20-year-old woman with fulminant hepatitis. The only available donor was her 54-year-old father-in-law of an incompatible blood type. The initial isoagglutinin titer was 2048x. She received 375 mg/m2 of anti-CD20 antibody 3 days before the living donor liver transplantation with concomitant splenectomy. Despite daily plasma exchanges after transplantation, the isoagglutinin titer started to shoot up to its maximum value of 2048x, with a sudden decline in the bile output. High-dose intravenous immunoglobulin (0.6 g/kg) was given after the plasma exchanges; thereafter, her liver function tests stabilized without a further increase in the isoagglutinin titer. We showed the effectiveness of high-dose intravenous immunoglobulin for the management of the rebound elevation of isoagglutinin titer. The combination of anti-CD20 antibody and daily plasma exchanges seemed ineffective for such a situation. This strategy might be another management option for ABO incompatible liver transplantation.
