Clinical validation of preoperative serum markers for liver fibrosis in living donor liver transplantation recipients.

Purpose: To validate the reliability of fibrosis markers as predictors of graft survival in living donor liver transplantation (LDLT) recipients.

Methods: We reviewed data retrospectively, from 163 patients who underwent adult LDLT with preoperative measurements of type IV collagen (CIV), Mac-2 binding protein glycosylation isomer (M2BPGi), and hyaluronic acid (HA). Patients were divided into high and low groups for each biomarker, based on optimal cutoff values, and graft loss within 6 months was evaluated in each group.

Novel protocol for prevention from hepatitis B reactivation following living-donor liver transplantation.

Aim: Reactivation of hepatitis B virus (HBV) after liver transplantation (LT) remains a problem; thus, development of more effective HBV reactivation prophylaxis is desirable. We evaluated the efficacy of a combination of a long-term nucleotide analog (NA), such as entecavir (ETV) or tenofovir alafenamide (TAF), and short-term hepatitis B immunoglobulin (HBIG) in preventing HBV reactivation and compared it with conventional HBV prophylaxis.

Methods: Between February 1999 and August 2023, 135 patients underwent living-donor liver transplantation for liver cirrhosis or acute liver failure caused by HBV infection or received an LT from a hepatitis B core antibody-positive donor.

Outcome of hepatectomy after systemic therapy for hepatocellular carcinoma: a Japanese multicenter study.

Background And Purpose: In recent years, new systemic therapies have been developed for hepatocellular carcinoma (HCC). The aim of this study was to evaluate the prognosis of patients with unresectable HCC treated with R0 hepatectomy after systemic therapy.

Methods: Data from 27 patients who underwent hepatectomy for HCC after systemic therapy at six facilities were analyzed retrospectively.

The Association of Transferrin Receptor with Prognosis and Biologic Role in Intrahepatic Cholangiocarcinoma.

Background: Ferroptosis is a cell death caused by iron-dependent accumulation of lipid peroxidation. Transferrin receptor (TFR) is a ferroptosis-related protein responsible for iron transport. The detailed biologic role of TFR in intrahepatic cholangiocarcinoma (ICC) is not fully elucidated.

The impact of perioperative synbiotics treatment in living-donor liver transplantation after induction of early enteral nutrition.

Purpose: Infectious complications, particularly post-transplant sepsis, have a critical impact on postoperative outcomes. This study examined the effects of perioperative synbiotic treatment on postoperative outcomes in patients receiving early enteral nutrition.

Methods: We reviewed 210 living-donor liver transplantation procedures and retrospectively analyzed the postoperative outcomes with and without perioperative synbiotic treatment (live lactic acid bacteria, bifidobacteria, and oligosaccharides) 5 days before and after living-donor liver transplantation.

Association of serum lactate dehydrogenase with prognosis and tumor metabolism in patients with hepatocellular carcinoma treated with atezolizumab plus bevacizumab therapy.

Purpose: Treatment outcomes are predicted by analyzing peripheral blood markers such as serum lactate dehydrogenase (LDH). We conducted this study to investigate whether serum LDH levels can predict the prognosis of patients treated with atezolizumab plus bevacizumab (ATZ/BEV) therapy for hepatocellular carcinoma (HCC) and whether LDH levels correlate with metabolic changes.

Methods: We enrolled 66 HCC patients treated with ATZ/BEV.

Prediction of portal venous pressure in living donor liver transplantation: A retrospective study.

Liver transplantation is the definitive treatment for advanced liver cirrhosis with portal hypertension. In Japan, the scarcity of deceased donors leads to reliance on living donors, often resulting in smaller grafts. Managing portal venous pressure (PVP) is critical to prevent fatal posttransplant complications.

What is the crux of successful living-donor liver transplantation for recipients aged 70 and beyond?

Aim: There is limited evidence regarding the feasibility of living-donor liver transplantation (LDLT) for patients aged over 70. The aims of this study were to assess postoperative outcomes in elderly recipients and to ascertain the potential feasibility and acceptability of LDLT.

Methods: Data were collected from 762 recipients, including 26 in the elderly group (aged ≥70) and 736 in the younger group (aged <70), and reviewed even by propensity score matching (PSM).

Is preoperative weight reduction of living-donor liver transplant recipients and donors harmful to postoperative outcomes?

Purpose: Although the incidence of recipients and donors with overweight and obesity is increasing worldwide, few reports have focused on outcomes of preoperative weight reduction (WR) in living-donor liver transplantation (LDLT). Therefore, we examined the outcomes and the impact of WR on the postoperative course.

Methods: We analyzed 217 consecutive LDLT procedures performed from 2017 to 2022.

Impact of electrical muscle stimulation on serum myostatin level and maintenance of skeletal muscle mass in patients undergoing living-donor liver transplantation: Single-center controlled trial.

Aim: Sarcopenia is reportedly associated with a poor prognosis in patients who undergo living-donor liver transplantation (LDLT), most of whom are not able to tolerate muscle strengthening exercise training. Myostatin is one of the myokines and a negative regulator of skeletal muscle growth. The clinical feasibility of an electrical muscle stimulation (EMS) system, which exercises muscle automatically by direct electrical stimulation, has been reported.

What Are Risk Factors for Graft Loss in Patients Who Underwent Simultaneous Splenectomy During Living-donor Liver Transplantation?

Background: The consensus that portal venous pressure modulation, including splenectomy (Spx), prevents portal hypertension-related complications after living-donor liver transplantation (LDLT) has been established. However, little evidence about the risk factors for graft loss after simultaneous Spx during LDLT is available. This study aimed to identify the independent predictors of graft loss after simultaneous Spx during LDLT.

Impact of ACSL4 on the prognosis of hepatocellular carcinoma: Association with cancer-associated fibroblasts and the tumour immune microenvironment.

Background & Aims: Recently, the association between hepatocellular carcinoma (HCC) and ferroptosis has been the focus of much attention. The expression of long chain fatty acyl-CoA ligase 4 (ACSL4), a marker of ferroptosis, in tumour tissue is related to better prognosis in various cancers. In HCC, ACSL4 expression indicates poor prognosis and is related to high malignancy.

A successful case of deceased-donor liver transplantation from a donor with Marfan syndrome: a case report.

Background: Liver transplantation is the definitive therapy for patients with decompensated cirrhosis. Marfan syndrome is a systemic inheritable connective tissue disease associated with fibrillin-1 gene mutations, which cause abnormalities in connective tissue. Vascular changes due to Marfan syndrome occur mostly in the main vessels due to the high amount of connective tissue within the vessel wall and the high pressure and blood flow to which they are exposed.

Feasibility of venous cuff using an open round ligament or inferior mesenteric vein around the hepatic vein for a left lobe graft in living-donor liver transplantation.

Living-donor liver transplantation (LDLT) is an established treatment for patients with end-stage liver disease or acute liver failure, and outflow reconstruction is considered one of the most vital techniques in LDLT. To date, many strategies have been reported to prevent outflow obstruction, which can be refractory to liver dysfunction and can cause life-threatening graft loss or mortality. In addition, in this era of laparoscopic hepatectomy in donor surgery, especially LDLT using a left liver graft, it has been predicted that cutting the hepatic vein with automatic linear staplers will lead to more outflow-related problems than with conventional open hepatectomy because of the short neck of the anastomosis orifice.

Association of gut microbiota with portal vein pressure in patients with liver cirrhosis undergoing living donor liver transplantation.

Background And Aim: Many recent studies have shown a relationship between various systemic diseases and the gut microbiota (GM), with the gut-liver axis receiving particular attention. In contrast, no report has comprehensively shown the effects of GM on the pathophysiology of patients undergoing living donor liver transplantation (LDLT).

Method: We enrolled 16 recipients who underwent LDLT for liver cirrhosis, and 17 donors constituted the reference group.

Pretreatment eosinophil count predicts response to atezolizumab plus bevacizumab therapy in patients with hepatocellular carcinoma.

Aim: Pretreatment peripheral blood markers have value in predicting the treatment outcome of various cancers. In particular, the eosinophil count has recently gained attention. However, no study has reported the influence of the pretreatment eosinophil count on the outcomes of atezolizumab plus bevacizumab (ATZ/BEV), which is the recommended first-line systemic therapy for unresectable hepatocellular carcinoma (u-HCC).

Effect of Early Enteral Nutrition on Graft Loss After Living Donor Liver Transplantation: A Propensity Score Matching Analysis.

Background: This study aimed to elucidate the effect of early enteral nutrition on graft loss within 12 h after living-donor liver transplantation (LDLT) using propensity score-matching analysis and subsequently examine the risk factors for graft loss after LDLT.

Methods: We retrospectively reviewed the data of 467 LDLT patients who were assigned to the early and non-early groups based on the optimal cutoff value of 12 h for the starting time of early enteral nutrition after LDLT to predict graft loss.

Results: The 1-year graft survival rate of the early group before propensity score-matching was 92.

Impact of albumin-lymphocyte-platelet-C-reactive protein index as a prognostic indicator of hepatocellular carcinoma after resection: Associated with nuclear factor erythroid 2-related factor 2.

Aim: To investigate the prognostic value of the preoperative albumin-lymphocyte-platelet-C-reactive protein (ALPC) index in patients with hepatocellular carcinoma (HCC) undergoing curative hepatectomy. We also evaluated the relationship between the ALPC index and the phosphorylated nuclear factor erythroid 2-related factor 2 (p-Nrf2) levels.

Methods: Data were analyzed retrospectively from 256 patients who underwent resection for HCC.

Transferrin Receptor is Associated with Sensitivity to Ferroptosis Inducers in Hepatocellular Carcinoma.

Purpose: Transferrin receptor (TFR), a membrane protein that has a critical role in the transport of iron into cells, is known to be a ferroptosis-related marker. Although TFR is reported to be abundantly expressed in tumor cells, its relationship with ferroptosis inducers in hepatocellular carcinoma (HCC) remains unclear.

Methods: The authors performed immunohistochemical staining of TFR and divided 350 HCC patients into two groups according to its expression.

Caution to Poor Adherence With Immunosuppressant Medication That Causes Coma-Onset Autoimmune Encephalitis: A Case Report and Literature Review.

Autoimmune encephalitis after liver transplantation (LT) is a rare disorder. This is because patients are usually in an immunosuppressed state after LT. Here, we report a rare case of autoantibody-negative autoimmune-encephalitis-induced coma after living-donor (LD) LT.

Treatment strategy for hepatocellular carcinoma recurrence in the transplant era: Focusing on the Japan criteria.

Purpose: To clarify the Japan criteria (JC), as proposed in 2019, in order to identify the most appropriate treatment methods for hepatocellular carcinoma (HCC) recurrence and assess the feasibility of pre-living donor liver transplantation (LDLT) downstaging within these criteria.

Methods: The subjects of this study were 169 LDLT patients with HCC recurrence. We performed univariate and multivariate analyses of the factors contributing to HCC recurrence after LDLT and clarified the post-transplant outcomes of pre-LDLT downstaging.
