Background/Aim The Kyushu Study Group of Clinical Cancer (KSCC) previously reported the safety and efficacy of neoadjuvant chemotherapy with mFOLFOX6 + bevacizumab for H2/H3 liver metastases of colorectal cancer. The aim of the current study was to evaluate the resectability of these metastases before and after chemotherapy as determined by independent liver surgeons. Methods Between May 2008 and April 2010, 40 patients were registered in a multicenter phase 2 trial of neoadjuvant chemotherapy (KSCC 0802). In Study 1, 5 independent liver surgeons from five different KSCC centers evaluated the resectability of liver metastases of colorectal cancer based on imaging studies performed before and after chemotherapy. Each surgeon was blinded to the other surgeons' evaluations. In addition, no information about the patients' characteristics was provided. In Study 2, 3 surgeons evaluated the resectability of these lesions based on imaging studies with discussion with each other, with the surgeons being provided with information on the patients' characteristics. Results In Study 1, 13 patients (36.1%) were evaluated to be resectable at baseline, whereas 17 patients (47.2%) were evaluated to be resectable after chemotherapy. In Study 2, 4 patients (11.1%) were evaluated to be resectable at baseline, compared to 23 patients (63.9%) after chemotherapy. Conclusion Neoadjuvant chemotherapy with mFOLFOX6 + bevacizumab was confirmed to increase the resectability of non-resectable liver metastases of colorectal cancer according to the independent assessments of surgeons.

Abstract: Aims: The aim of this study was to investigate the relationship between the use of bevacizumab (Bmab) in addition to oxaliplatin (OX), the development of sinusoidal obstruction syndrome (SOS) and the changes in splenic volume as an indicator of the protective effect of Bmab against OX-induced SOS. Methods: Seventy-nine patients who received OX-based chemotherapy with (OX + Bmab group: n = 48) or without Bmab (OX group: n = 31) for colorectal liver metastases were included in this study. The changes in splenic volume after chemotherapy were evaluated in the two groups. Furthermore, the relationship between the changes in splenic volume and SOS were analyzed in the 55 patients who underwent hepatectomy. Results: A significant increase in the splenic volume was observed in the OX group, but not in the OX + Bmab group. The increase in the splenic volume relative to baseline was significantly higher in the OX group than in the OX + Bmab group (39.1% vs. 2.3%, p < 0.0001). The incidence of moderate or severe SOS was significantly higher in the OX group than in the OX + Bmab group (50.0% vs. 16.0%, p = 0.0068), and the increase in the splenic volume was significantly higher in the patients with SOS than in those without SOS (42.9% vs. 9.9%, p = 0.0001). A multivariate analysis identified the increase in the splenic volume as an independent predictor of the development of SOS. Conclusions: This study demonstrated that the inhibition of splenic volume enlargement might be a useful indicator of the protective effect of Bmab against OX-induced SOS. [Copyright &y& Elsevier]

Abstract: Aims: Gefitinib shows prominent anti-tumor activity against advanced or recurrent non-small cell lung cancer (NSCLC). However, most gefitinib-responsive patients ultimately relapse. We reviewed postoperatively recurrent NSCLC patients who received gefitinib treatment, and analyzed both the clinical features and manifestations of treatment failure in patients who initially responded to gefitinib. Methods: From 2002 to 2006, gefitinib was administered to in 34 postoperative recurrent lung adenocarcinoma patients. There were 13 men and 21 women with a mean age of 65years. Twenty patients had never smoked while 14 were former smokers. Epidermal growth factor receptor (EGFR) gene mutation was measured using surgical specimens of the primary tumor. Results: The study group showed 1 complete response, 16 partial responses, 7 stable diseases and 8 progressive diseases. Mutations of EGFR gene were detected in 20 of 34 patients. Only the presence of EGFR gene mutations was significantly associated with the clinical response of gefitinib in our limited study (p =0.036). In 9 of 12 responders, gefitinib treatment failed due to the appearance of new lesions. Conclusions: Gefitinib was significantly effective for patients with mutations of the EGFR gene and most responders failed due to the appearance of new lesions without progression of the pre-existent target lesions.

Oxaliplatin-based adjuvant chemotherapy may be associated with debilitating peripheral sensory neuropathy (PSN) in patients with high-risk stage II colon cancer. This open-label, multicenter, randomized phase III trial was conducted as a prospective pooled analysis to investigate the non-inferiority of 3 versus 6 months of adjuvant oxaliplatin-based chemotherapy. From 12 February 2014 to 31 January 2017, 525 Asian patients with high-risk stage II colon cancer were randomly assigned to 3- and 6-month treatment arms. The treatment consisted of either modified fluorouracil, leucovorin, and oxaliplatin (mFOLFOX6) or capecitabine combined with oxaliplatin (CAPOX). The primary end point was disease-free survival (DFS). The secondary end points were treatment compliance and safety. Of the 525 randomized patients, 11 were not treated. Among the 514 participating patients (255 in the 3-month arm; 259 in the 6-month arm), 432 (84%) received CAPOX, and 184 (36%) presented with T4 as a high-risk factor for recurrence. The 3-year DFS rate was 88.2% in the 3-month arm and 87.9% in the 6-month arm [hazard ratio (HR), 1.12; 95% confidence interval (CI), 0.67-1.87]. With CAPOX, the 3-year DFS rate was 88.2% in the 3-month arm and 88.4% in the 6-month arm (HR, 1.13; 95% CI, 0.65-1.96). The discontinuation rate in the 3- and 6-month arms was 10% and 31% for mFOLFOX6 (P = 0.0193), and 15% and 35% for CAPOX (P < 0.0001), respectively. The incidence of grade ≥2 PSN was significantly lower in the 3-month arm than in the 6-month arm (16% and 43%, respectively, P < 0.0001). Three months of combination therapy presented significantly less grade ≥2 PSN than the respective 6-month regimen. The shortened therapy duration did not affect the 3-year DFS rate, suggesting that a 3-month course of CAPOX can be an effective treatment option. UMIN Clinical Trials Registry, UMIN000013036 and Japan Registry of Clinical Trials, jRCTs031180128. • Oxaliplatin-based adjuvant chemotherapy is associated with PSN in patients with high-risk stage II colon cancer. • Three-month oxaliplatin-based adjuvant chemotherapy showed less grade ≥2 PSN than the 6-month regimen. • Three-month oxaliplatin-based adjuvant chemotherapy did not affect the 3-year DFS rate compared with the 6-month regimen. • A three-month course of adjuvant CAPOX can be an option for high-risk stage II colon cancer.

Abstract Chimeric mice with humanized liver were first established by transplanting primary human hepatocytes (PHHs) isolated from a Japanese 27-year-old donor into complementary DNA-urokinase-type plasminogen activator/severe combined immunodeficiency mice. The PHHs from the Japanese donor increased more than 100-fold in the mouse liver, and human hepatocytes purified from the chimeric mouse liver (hcPHs) were successfully transplanted into second-passaged mice. These PHHs and hcPHs can produce human albumin and preserve many liver-specific enzyme genes, which are important for liver function. Interestingly, hepatitis B virus can be infected with these chimeric mice; hepatitis B viral DNA and hepatitis B surface antigen levels were detectable. In conclusion, hcPHs can be an ideal cell source for analysis of human hepatocytes. Highlights • Chimeric mice with humanized liver were first established by transplanting primary human hepatocytes (PHHs) isolated from a Japanese 27-year-old donor into cDNA-uPA/SCID mice. • The PHHs from a Japanese donor increased more than 100-fold in the mouse liver, and human hepatocytes purified from the chimeric mouse liver (hcPHs) were successfully transplanted into second-passaged mice. • These PHHs and hcPHs can produce human albumin and preserve many liver-specific enzyme genes.

Background Sarcopenia is an independent predictor of death after living-donor liver transplantation (LDLT). However, the ability of the Asian Working Group for Sarcopenia criteria for sarcopenia (defined as reduced skeletal muscle mass plus low muscle strength) to predict surgical outcomes in patients who have undergone LDLT has not been determined. Methods This study prospectively enrolled 366 patients who underwent LDLT at Kyushu University Hospital. Skeletal muscle area (determined by computed tomography), hand-grip strength, and gait speed were measured in 102 patients before LDLT. We investigated the relationship between sarcopenia and surgical outcomes after LDLT performed in three time periods. Results The number of patients with lower skeletal muscle area has increased to 52.9% in recent years. The incidence of sarcopenia according to the Asian Working Group for Sarcopenia criteria was 23.5% (24/102). Patients with sarcopenia (defined by skeletal muscle area and functional parameters) had significantly lower skeletal muscle area and weaker hand-grip strength than did those without sarcopenia. Compared with non-sarcopenic patients, patients with sarcopenia also had significantly worse liver function, greater estimated blood loss, greater incidence of postoperative complications of Clavien-Dindo grade IV or greater (including amount of ascites on postoperative day 14, total bilirubin on postoperative day 14, and postoperative sepsis), and longer postoperative hospital stay. Multiple logistic regression analysis revealed sarcopenia as a significant predictor of 6-month mortality. Conclusions The combination of skeletal muscle mass and function can predict surgical outcomes in LDLT patients. [ABSTRACT FROM AUTHOR]

Abstract Thrombectomy is a routine or common practice for treating organized portal vein thrombosis (PVT) during liver transplantation. However, this procedure is often performed in a blinded fashion and can result in insufficient thrombectomy or devastating consequences such as injury to the retropancreatic portal vein where prompt repair is very difficult. To overcome these drawbacks for blind thrombectomy, we herein describe a new technique that makes complex thrombectomy safe and easy under direct ultrasound vision. This procedure is readily available and highly reproducible and can be used as the standard procedure for treating extensive PVT. Highlights • A new technique that makes complex thrombectomy safe and easy under direct ultrasound vision is proposed. • Thanks to a real-time vision of the tip of the tonsil clamp, the residual thrombus, and the inner walls of the deep portal vein, the residual thrombus can be safely and completely peeled off from the wall of the portal vein. • This procedure is readily available and highly reproducible and can be used as the standard procedure for treating extensive portal vein thrombosis.

Large-for-size syndrome (LFSS) is controversial in pediatric living donor liver transplantation patients and is associated with a poor graft outcome. Similar situations in deceased donor liver transplantation (DDLT) in adults have not been reported frequently, and there are no official guidelines worldwide. Deceased donation is extremely limited in Japan, and when a larger liver is allocated for a very sick small recipient in Japan, transplantation with a plan to address LFSS might be necessary. The patient is a 58-year-old female patient who had acute liver failure with coma. The graft-recipient weight ratio (GRWR) was 2.74%. Although the graft was enlarged by reperfusion, the intraoperative Doppler ultrasound, performed after reperfusion, showed sufficient graft in-flow and out-flow. However, when the liver graft was situated appropriately into the right phrenic space supported by the rib cage and diaphragm, the blood flow in the hepatic vein and portal vein was significantly reduced. Graft blood flow did not improve without removing it from the right subphrenic space. Therefore, we decided to perform an in situ graft posterior segmentectomy, so that the graft right lobe was properly accommodated in the patient's right subphrenic space. After the segmentectomy of the graft, an intraoperative Doppler sonogram showed significantly improved blood flow. LFSS could be a significant operative challenge in adult DDLT, especially in areas with limited chances of DDLT. In situ posterior segmentectomy in the demarcated area could be a solution for treating patients with LFSS. [ABSTRACT FROM AUTHOR]

Although Roux-en Y hepaticojejunostomy was previously recommended for the biliary reconstruction in liver transplantation for primary sclerosing cholangitis (PSC), some recent reports showed no difference in the graft survival between Roux-en Y and duct-to-duct anastomosis in deceased-donor liver transplantation. On the other hand, considering the risk of recurrence and the short length of the bile duct of the graft, duct-to-duct biliary anastomosis has never been reported in a patient undergoing living-donor liver transplantation (LDLT) for PSC. A 45 year-old male underwent LDLT using a left-lobe graft donated from his brother. Cholangiography showed no lesion in his common bile duct and duct-to-duct anastomosis was chosen for him. Fifteen months later, he suffered cholangitis due to PSC recurrence and endoscopic retrograde cholangiography was performed. The stents were inserted into his B2 and B3, and he remains well. Because of the ability to easily manage biliary complication, duct-to-duct biliary reconstruction may become the first choice in LDLT for PSC without common bile duct lesions. [ABSTRACT FROM AUTHOR]

Introduction Appropriate antiviral treatment is essential for living donor liver transplantation (LDLT) to be effective for treating hepatitis C. However, it has never been reported that pre-LDLT genetic analyses of both host and virus, with prediction of the outcome of post-LDLT antiviral treatment, indicated LDLT for a borderline case. Case Report We have reported the case of a 68-year-old woman with liver cirrhosis caused by genotype 1b hepatitis C, a history of ruptured esophageal varices, and adequately controlled minor ascites. Her liver function was classified as Child–Pugh grade B. The donor was a 42-year-old woman with an estimated left lobe graft volume (GV) of 33.8% based on the standard liver volume of the recipient. Molecular analyses used to confirm the indication of LDLT for this combination revealed the following: The rs8099917 genotype was T/T in the donor and recipient, the HCV core protein was double wild type, there were no mutations in the interferon sensitivity-determining region, and 8 mutations were found in the interferon/ribavirin resistance-determining region. LDLT was performed because very high sensitivity to interferon treatment was predicted. Discussion Six months after LDLT and uneventful post-LDLT courses, pegylated interferon-α2a and ribavirin were administered under immunosuppression with cyclosporine and mycophenolate mofetil. This regimen was continued for 48 weeks, resulting in a viral response at 10 weeks and a sustained viral response, as predicted. Conclusions We have reported the usefulness of molecular analyses of host and viral factors for indicating LDLT to treat hepatitis C in a borderline case. [ABSTRACT FROM AUTHOR]

Abstract: Introduction: Few studies to date have investigated the causes of late graft mortality after living-donor liver transplantation (LDLT) for primary biliary cirrhosis (PBC). Patients and Methods: Fifty-five LDLTs for PBC were retrospectively reviewed. Factors prognostic of graft survival after LDLT were investigated, and histologic findings in patients with late graft loss were assessed. Results: The 1-, 5-, and 10-year cumulative graft survival rates were 85.1%, 82.5%, and 66.9%, respectively. Multivariate Cox regression analysis found that male donor and ≥4 HLA mismatches were independently associated with poor graft survival. Among the 13 grafts lost, 5 were lost >1 year after LDLT, including 1 each due to chronic rejection, veno-occlusive disease, and obliterative portal venopathy, and 2 to other causes. Pathologic reviews of the serial biopsy specimens and explanted grafts from these 5 patients, with graft rejections from “chronic immune-mediated reaction syndrome,” showed reciprocal changes over time. No patient died of recurrent PBC. Conclusions: Male donor and ≥4 HLA mismatches were independent factors associated with poor graft survival. Late graft mortality after LDLT for PBC in some patients was due to chronic immune-mediated reaction syndrome, including chronic rejection, veno-occlusive disease, and obliterative portal venopathy, but not to recurrent PBC.

Abstract: Background: The Model for End-Stage Liver Disease (MELD) score has been validated to predict the mortality rate of patients with various chronic liver diseases on the waiting list for liver transplantation (LT). The aim of this study was to assess the value of the postoperative MELD scoring system as an early postoperative predictor of outcome in patients undergoing living donor LT (LDLT). Methods: A retrospective analysis of 217 adult-to-adult LDLT patients was performed. The values of the MELD score on various postoperative days (PODs) as predictors of graft loss within 6 months after LDLT were examined by calculating the areas under the receiver operating characteristic (AUROC) curves. The 6-months graft survival rates were compared between patients with (n = 22) and without (n = 195) graft loss. Univariate and multivariate analyses were performed to identify the factors associated with mortality. Results: The MELD score on POD2 was a predictor of graft loss, with an AUROC c-statistic of 0.779, a specificity of 79.5%, and a sensitivity of 68.2% at optimal cutoff, whereas the preoperative MELD score c-statistic was 0.605 with 44.6% sensitivity. Multivariate analyses for postoperative mortality revealed MELD-POD2 ≥19 (odds ratio, 5.601; 95% confidence interval [CI], 1.395–4.508; P = .0009) as an independent predictor of short-term graft loss following LDLT, in addition to preoperative hospitalization status. Later MELD POD scores were also predictive of graft loss. Conclusions: The early postoperative MELD scoring system is feasible as an index for prediction of postoperative mortality following LDLT.

Abstract: We have proposed risk factors for tumor recurrence, such as tumor nodule ≥5 cm and des-gamma-carboxy prothrombin ≥300 mAU/mL after living donor liver transplantation (LDLT) for hepatocellular carcinoma (HCC). The aim of this study was to clarify the risk factors for HCC recurrence and mortality within our criteria. We enrolled 152 adult recipients who had undergone LDLT for end-stage liver disease with HCC who met our criteria. The recurrence-free survival rates after LDLT were calculated. Risk factors for tumor recurrence were identified. On univariate analysis, factors affecting recurrence-free survival were pretransplant treatment for HCC, neutrophil-to-lumphocyte ratio (NLR) >4, alpha-fetoprotein ≥400 ng/mL, ≥5 nodules, and bilobar tumor distribution. Multivariate analysis identified that NLR >4 and ≥5 nodules were independent risk factors for tumor recurrence after LDLT (P = .003 and P = .002, respectively). Two-step selection criteria enable selection of patients who have high-risk of tumor recurrence. [Copyright &y& Elsevier]

Reconstruction of multiple venous orifices of a right lobe graft is a time-consuming and troublesome procedure in right lobe living-donor liver transplantation. In the current study, we present a new venous reconstruction technique for a right lobe graft with multiple and complex hepatic vein (HV) orifices, in which procurement of the recipient's left portal vein was performed in situ to keep the anhepatic period to a minimum. All of the HV orifices were reconstructed together at the back table, while maintaining patency of the recipient's systemic and splanchnic circulation. A homologous vein graft and veno-venous bypass were not necessary. All HVs were patent during the follow-up and the patient was free from complications. In conclusion, the present technique is readily available for reconstruction of complex and multiple HV tributaries, while avoiding a long anhepatic time and the use of veno-venous bypass.

Abstract: Introduction: The optimal surgical technique has not been elucidated that reduces the occurrence of biliary strictures after living donor liver transplantation (LDLT). Method: We performed retrospective analysis of 193 consecutive LDLTs, including 78 right and 115 left lobe grafts. An external biliary stent was used for all of the cases. Results: The overall 1-, 3-, and 5-year biliary stricture–free survival rates were 87.5%, 85.3%, and 85.3%, respectively. The 1- and 3-year biliary stricture–free survival rates for duct-to-duct reconstruction were 86.9% and 84.9%, and those for hepaticojejunostomy were 90.1% and 80.8%, respectively. A multivariate analysis revealed that the original number of graft bile ducts greater than the number of external stents, right lobe grafts, bile leaks, and recipient age older than 60 years represented the significant risk factors (P < .05) to develop a biliary stricture after LDLT. All cases with biliary strictures (n = 61) were initially managed nonsurgically, but 4 patients ultimately required interventions. Conclusions: Biliary reconstruction in LDLT using an appropriate number of external stents resulted in fairly acceptable outcomes. However, not only the proper use of stents or graft selection, but also nonsurgical factors, are important factors that determine the incidence of biliary strictures after LDLT.

Portal decompression is an approach for reducing portal overflow caused by small-for-size syndrome. We report the case of a patient who recovered from rapidly progressing hyperbilirubinemia caused by a small graft by decompressing portal overflow with splenic artery embolization following a living donor liver transplantation (LDLT). The patient was a 54-year-old man with end-stage liver disease secondary to alcoholic liver cirrhosis; the donor was his 54-year-old wife. The graft volume of the left lobe was 444 mL, which was 34.8% of the standard liver volume (SLV) and insufficient for the recipient; thus, the plan was to use the right lobe for the graft. The patient underwent LDLT with a right lobe graft; the volume to SLV ratio was 39.1%, and the graft-to-recipient-weight ratio was 0.72%. Although portal pressure was low during the operation, the patient eventually developed small-for-size syndrome after LDLT. It was conceivable that because the patient had splenomegaly, portal decompression would be effective. Splenic arterial embolization was performed successfully on postoperative day (POD) 7. The patient's total bilirubin level was increased to 40 mg/dL on POD16. Decreased portal flow, which was shown by ultrasound screening to be “to-and-flo,” increased again on POD23 to one-third of that on POD1. He was discharged without any infectious complications. Additional splenic artery embolization after LDLT may be a convenient option for reducing portal overflow for patients with splenomegaly if the portal decompression was not performed for some reason at the surgery.

Abstract: Although it has been recognized that interferon (IFN) treatment is crucial for recurrent hepatitis C after liver transplantation, its benefits have not been determined among patients without a sustained viral response (SVR). Methods: Eighty patients who received IFN plus ribavirin treatment after living donor liver transplantation were grouped as follows: group I (n = 18) SVR; group II (n = 25) no-SVR but viral response [VR] positive; Group III (n = 13) no-VR but biochemical response [BR] positive; and group IV (n = 24) no-VR and no-BR. Results: In groups II and III, not only the histological activity grade and fibrosis stage, but also the serum parameters including transaminases and type IV collagen were stable for 3 years after induction of IFN-based treatment. In group I, the activity grade and fibrosis stage significantly improved (P < .01). In group IV, the fibrosis stage significantly deteriorated (P < .01); the serum transaminases and type IV collagen were significantly higher than the other groups (P < .01). The mean duration of IFN treatment was significantly longer among group II (96 weeks) compared with the other cohorts (P < .05). The 5-year graft survival rate in groups II (91%) and III (100%) were comparable to those of group I (100%); group IV (62%) was significantly lower than the other groups (P < .05). Conclusion: IFN treatment was beneficial even among subjects with IFN-dependent VR or BR, although they did not achieve SVR. [Copyright &y& Elsevier]

Abstract: Background: We sought to elucidate the influence of donor age in living donor liver transplantation (LDLT) using either left lobe (LL) or right lobe (RL) grafts. Methods: Recipients (n = 232) were categorized as: group O/LL (LL, donor age >50, n = 20); group Y/LL (LL, donor age ≤50, n = 140); Group O/RL (RL, donor age >50, n = 12); and group Y/RL (RL, donor age ≤50, n = 61). We compared post-LDLT graft functions. Results: Among LL LDLT, the incidence of small-for-size syndrome was significantly greater for group O/LL compared with group Y/LL (60.0% vs 16.3%, P < .01). However, the cumulative 5-year graft survivals were 73.8% in group O and 76.7% in group Y without substantial difference. In RL LDLT, the post-LDLT morbidity and mortality were similar for group O/RL and group Y/RL. Conclusion: Partial liver grafts, even though LL grafts, from older donors can be used safely with caution in LDLT. [Copyright &y& Elsevier]

Abstract: Introduction: Accurate pretransplant estimation of the recipient''s standard liver volume (SLV) is important. The purpose of this study was to compare reported formulas for clinical estimation of liver volume among Japanese adults. Methods: We reviewed data on 70 healthy adults (46 men, 24 women, ages 20 to 65 years old) evaluated for living donor liver transplantation. Liver volume (LV) was measured using two- or three-dimensional computed tomography volumetry (CTV). The formulas of DeLand (LV = 1020 × body surface area [BSA] − 220), Urata (LV = 706.2 × BSA + 2.4), Noda (LV = 50.12 × BW0.78), Heinemann (LV = 1072.8 × BSA − 345.7), Vauthey (LV = 18.51 × BW + 191.8) and Yoshizumi (LV = 772 × BSA) were applied to estimate LV. We calculated the differences for individual donors betwen CTV and LV estimated by each formula. Results: Mean LVs as estimated by the formulae of DeLand and Heinemann et al were significantly greater (P < .01) than the mean CTV, while LV estimated by the formula of Urata was significantly less (P < .05) than the CTV. The formulas of DeLand and Heinemann overestimated LV, while the formula of Urata underestimated it. The formulae of Noda et al and Yoshizumi et al tended to underestimate the LV when the CTV was greater than 1600 cm3. When the Yoshizumi formula was applied, the number of donors with an acceptable difference (±15%) between CTV and estimated LV was 55 (78.6%). Conclusions: The Yoshizumi formula was applicable, especially for patients with a BSA < 2.0, whereas the well-known Urata formula made LV underestimates. [Copyright &y& Elsevier]

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 2048×. 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 2048×, 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.
