Article Abstract
Introduction: Drug-induced liver injury (DILI) associated with 5-aminosalicylic acid (5-ASA) is a rare but potentially life-threatening adverse event.
Case Presentation: We report the case of a 58-year-old woman with ulcerative colitis who developed DILI after initiating maintenance therapy with the multimatrix system 5-ASA. The patient presented with grade 4 liver enzyme elevation on day 98 after initiating 5-ASA and was admitted to the hospital. Blood tests revealed the mixed liver injury, and imaging studies showed no abnormalities except for mild lymph node enlargement. Liver biopsy revealed acute lobular hepatitis with interfacial activity. The patient's score on the International Autoimmune Hepatitis Group 1999 revised scoring system was a total score of 10, causing a suspicion for the diagnosis of autoimmune hepatitis. The DDW-J 2004 scale calculated a total score of six, indicating a high probability of DILI. We suspected DILI due to 5-ASA, and the 5-ASA formulations were discontinued. The patient was treated with ursodeoxycholic acid and neominophagen C, and her liver function gradually improved without steroid treatment. Finally, we definitively diagnosed DILI based on the pathological findings and clinical course after discontinuation of 5-ASA.
Conclusion: This case highlights the importance of monitoring liver function in patients receiving 5-ASA therapy.

Metabolic associated steatohepatitis (MASH) is a severe form of metabolic dysfunction-associated steatotic liver disease (MASLD) characterized by hepatocellular injury, inflammation, and fibrosis. Despite advances in understanding its pathophysiology, the molecular mechanisms driving MASH progression remain unclear. This study investigates the role of long non-coding RNA Linc01271 in MASLD/MASH pathogenesis, ant its involvement in the miR-149-3p/RAB35 axis and PI3K/AKT/mTOR signaling pathway.

Drug-induced hepatotoxicity (DIH), characterized by diverse phenotypes and complex mechanisms, remains a critical challenge in drug discovery. To systematically decode this diversity and complexity, we propose a multi-dimensional computational framework integrating molecular structure analysis with disease pathogenesis exploration, focusing on drug-induced intrahepatic cholestasis (DIIC) as a representative DIH subtype. First, a graph-based modularity maximization algorithm identified DIIC risk genes, forming a DIIC module and eight disease pathogenesis clusters.

Extracorporeal photopheresis (ECP) is a safe and effective therapy with long-established indications in treating T cell-mediated immune diseases, including steroid refractory graft-versus-host disease and chronic rejection after heart or lung transplantation. The ECP procedure involves collecting autologous peripheral blood leucocytes that are driven into apoptosis before being reinfused intravenously. ECP acts primarily through in situ exposure of recipient dendritic cells and macrophages to apoptotic cells, which then suppress inflammation, promote specific regulatory T-cell responses, and retard fibrosis.

Tislelizumab, an anti-PD-1 monoclonal antibody, is associated with immune-related hepatitis in 1.8% of cases, but reports of acute liver failure (ALF) remain exceedingly rare. We present a case of fulminant hepatitis and ALF following Tislelizumab therapy in a 55-year-old woman with locally advanced cervical adenocarcinoma.
