BACKGROUND: Previous studies have reported that hepatitis B virus (HBV) genotype is not a predictor of treatment response with nucleos(t)ide analogue (NUC) therapy. However, the impact of subgenotype on treatment response is unknown. AIM: To identify the effect of HBV subgenotype on treatment response. METHODS: In this retrospective study, the derivation dataset comprised patients from the EFFORT study (NCT00962533) telbivudine monotherapy group; patients infected with genotypes B or C from the GLOBE (NCT00057265) and 015 (NCT00131742) studies formed the validation dataset...

AIM: There are no beneficial therapies except for emergency liver transplantation for acute liver failure (ALF). However, in Japan where a serious problem of a shortage of donor livers still remains, therapies other than transplantation must be further investigated for patients with ALF. Pro-inflammatory cytokines promoting tissue destruction are predominant at an early phase of ALF. Corticosteroid (CS) influences monocyte/macrophage differentiation, by suppressing pro-inflammatory genes, indicating CS treatment might be beneficial during the early phase of ALF...

The administration of direct-acting antiviral agents (DAAs) to treat hepatitis C virus (HCV) infection has been reported to cause hepatitis B virus (HBV) reactivation. However, the actual conditions of HBV reactivation and the ideal timing of medical intervention have not been fully evaluated. We reported the cases of two female patients dually infected with HBV and HCV. Both patients were inactive HBV carriers. Although the serum HCV RNA levels promptly decreased after the initiation of DAA-based therapy, the serum HBV DNA levels gradually increased during DAA-based therapy, with the peak serum HBV DNA levels observed at 16 weeks after the initiation of DAA-based therapy in both cases...

Liver transplantation for metastatic neuroendocrine tumor (NET) in the liver used to be the main reason for liver transplantation for metastatic liver tumor. It is reported that liver transplantation in selected patients with nonresectable metastatic NET in the liver had favorable outcomes equivalent to liver transplantation for hepatocellular carcinoma. Recently, liver transplantation for colorectal liver metastasis (CRLM) has attracted attention. According to the SECA study in Oslo, liver transplantation for non-resectable CRLM had a high rate of recurrence but a favorable prognosis...

In Japan, hepatitis B or C virus infection has been a major health issue. For the prevention of liver-related deaths, multifaceted strategies have been taken against hepatitis virus. In Fiscal Year (FY) 2002, nationwide screening for hepatitis was started as a part of health examinations provided by municipal governments. From FY2007, the hepatitis treatment network has been strengthened by the nationwide establishment of regional government-based hepatitis treatment systems, comprising linked regional core centers, specialized institutions for hepatitis treatment, primary care physicians and regional governments...

Endoplasmic reticulum stress is associated with the pathophysiology of various liver diseases. Endoplasmic reticulum stress mediates the accumulation of abnormal proteins and leads to oxidative stress, cytoplasmic inclusion body formation and apoptosis in hepatocytes. Autophagy is a bulk degradation pathway for long-lived cytoplasmic proteins or damaged organelles and is also a major degradation pathway for many aggregate-prone and disease-causing proteins. We previously reported that rapamycin, a mammalian target of rapamycin inhibitor, activated autophagy and decreased proteasome inhibitor-mediated ubiquitinated protein accumulation, cytoplasmic inclusion body formation and apoptosis in hepatocytes...

Molecular signaling events associated with the necroinflammatory changes in nonalcoholic steatohepatitis are not well understood. To understand the molecular basis of NASH, we evaluated reversible phosphorylation events in hepatic tissue derived from Class III obese subjects by phosphoproteomic means with the aim of highlighting key regulatory pathways that distinguish NASH from NAFLD. Class III obese subjects undergoing bariatric surgery underwent liver biopsy (8 NOR, 8 simple steatosis and 8 NASH). Our strategy was unbiased, comparing global differences in liver protein reversible phosphorylation events across the 24 subjects...

AIM: Diabetes mellitus (DM) is a potential risk factor for hepatocarcinogenesis, especially in patients with hepatitis C virus (HCV) infection. We aimed to elucidate whether DM influences the surgical outcomes of patients with hepatocellular carcinoma (HCC). METHODS: Our patients were routinely controlled to keep urinary glucose excretion to less than 3.0 g/day before surgery, and the serum glucose level under 200 mg/dL after surgery. The surgical outcomes and postoperative complications of 112 patients with HCV-related HCC with DM (DM group) were compared to those of 112 propensity-matched patients without DM (non-DM group)...
