Polygenic Risk Score for Metabolic Dysfunction-Associated Steatotic Liver Disease and Steatohepatitis: A Narrative Review.

Metabolic dysfunction-associated steatotic liver disease (MASLD) and metabolic dysfunction-associated steatohepatitis (MASH) are spreading worldwide as the most critical causes of cirrhosis and hepatocellular carcinoma (HCC). Thus, improving the screening and managing strategies for patients with MASLD or MASH is necessary. A traditional non-systemic review provided this narrative.

Hepatitis A and E Viruses Are Important Agents of Acute Severe Hepatitis in Asia: A Narrative Review.

Acute-on-chronic liver failure (ACLF) and acute liver failure (ALF) are severe hepatitis that occur in patients with and without chronic liver diseases and/or cirrhosis, respectively, and both often result in death. Hepatitis A virus (HAV) and hepatitis E virus (HEV) infection can cause these severe conditions. We reviewed the role of HAV and HEV, which infect humans through the fecal-oral route, in ALF and ACLF in Asian countries.

Cholestasis in hepatitis E virus infection.

Hepatitis E virus (HEV) infection causes acute hepatitis, chronic hepatitis, particularly in compromised hosts, and various extrahepatic manifestations. HEV infection is reportedly associated with biliary-pancreatic diseases, such as gallstones, cholangitis, choledocholithiasis, and acute pancreatitis. Severe jaundice and prolonged cholestasis are also atypical manifestations of HEV infection.

Mapping of rehabilitation interventions and assessment methods for patients with liver cirrhosis: a scoping review.

Background: This scoping review aimed to delineate the detailed components of exercise therapy and the evaluation methods used for patients with liver cirrhosis.

Methods: The methodology involved searching the original PubMed, Web of Science, and Scopus for studies published between January 1975 and March 2025. The search was completed on 13 March 2025.

Coexistence of Relapsing Polychondritis, Crohn's Disease, and Pyoderma Gangrenosum Treated Successfully with Adalimumab: A Case Report and Literature Review.

Relapsing polychondritis (RP) is a rare, progressive, immune-mediated systemic inflammatory disease of unknown etiology characterized by recurrent inflammation of cartilaginous structures. Approximately 30% of RP cases are associated with autoimmune disease. However, co-occurrence of RP and Crohn's disease (CD) has rarely been reported.

Pruritus in Chronic Cholestatic Liver Diseases, Especially in Primary Biliary Cholangitis: A Narrative Review.

Patients with chronic cholestatic liver diseases often experience itch and struggle with this symptom. We discuss the mechanism of itch in patients with chronic cholestatic liver diseases, such as primary biliary cholangitis (PBC) and others, and their therapies, including ileal bile acid transporter (IBAT) inhibitors. In patients with PBC, there are high serum/plasma concentrations of multiple factors, including bile salts, bilirubin, endogenous opioids, lysophosphatidic acid (LPA), autotaxin, and histamine.

Aligning cellular and molecular components in age-dependent tertiary lymphoid tissues of kidney and liver.

Tertiary lymphoid tissues (TLTs) are ectopic lymphoid structures induced by multiple stimuli, including infection and tissue injuries; however, their clinical relevance in disease progression has remained unclear. We demonstrated previously that TLTs develop in mouse and human kidneys with aging and can be a potential marker of kidney injury and prognosis, and therapeutic targets. In addition, we found that two types of unique lymphocytes that emerge with aging, senescence-associated T cells and age-associated B cells, are essential for TLT formation in the kidney.

Human placental extract improves liver cirrhosis in mice with regulation of macrophages and senescent cells.

Introduction: Cirrhosis is a disease with poor prognosis that requires the development of a novel therapeutic approach alternative to liver transplantation. In this study, we focused on the placenta and aimed to clarify the effects of human placental extract (HPE) on cirrhosis.

Methods: A mouse model of carbon tetrachloride-induced cirrhosis was used to evaluate the effect of HPE administration subcutaneously and compared with the control group (n = 8 for each group).

Dasatinib and Quercetin as Senolytic Drugs Improve Fat Deposition and Exhibit Antifibrotic Effects in the Medaka Metabolic Dysfunction-Associated Steatotic Liver Disease Model.

Metabolic dysfunction-associated steatotic liver disease (MASLD) causes cellular senescence due to oxidative stress, endoplasmic reticulum stress, and ectopic fat deposition in the liver. Recently, dasatinib, an antitumor agent, and quercetin, a dietary supplement, were combined as a senolytic drug to eliminate senescent cells. Thus, this study aimed to examine the effects of dasatinib and quercetin administration on removing senescent cells and their therapeutic effects on MASLD in a medaka MASLD model.

Diffuse Large B-cell Lymphoma with Severe Lactic Acidosis and Liver Failure: A Case Report and Literature Review.

Among causes of liver failure, liver failure due to lymphocytic infiltration is rare. Unlike typical liver failure, some cases present with severe lactic acidosis and a poor prognosis. We herein report a case of diffuse large B-cell lymphoma with severe lactic acidosis and liver failure.

Effects of a selective PPARα modulator, sodium-glucose cotransporter 2 inhibitor, and statin on the myocardial morphology of medaka nonalcoholic fatty liver disease model.

Objective: Nonalcoholic fatty liver disease (NAFLD) is associated with metabolic dysregulation and is linked with various cardiovascular complications, which often lead to poor prognostic outcomes. To develop a standard therapy for NAFLD and to urgently address its complications, the current study aimed to investigate the mechanisms of NAFLD-related heart disease and the therapeutic effects of drugs targeting various metabolic pathways.

Methods: To explore the mechanism of NAFLD-related heart disease, a medaka model of high-fat diet-induced NAFLD was utilized.

Involvement of the liver-gut peripheral neural axis in nonalcoholic fatty liver disease pathologies via hepatic HTR2A.

Serotonin (5-HT) is one of the key bioamines of nonalcoholic fatty liver disease (NAFLD). Its mechanism of action in autonomic neural signal pathways remains unexplained; hence, we evaluated the involvement of 5-HT and related signaling pathways via autonomic nerves in NAFLD. Diet-induced NAFLD animal models were developed using wild-type and melanocortin 4 receptor (MC4R) knockout (MC4RKO) mice, and the effects of the autonomic neural axis on NAFLD physiology, 5-HT and its receptors (HTRs), and lipid metabolism-related genes were assessed by applying hepatic nerve blockade.
