A 74-year-old man developed hepatic injury after intravesical Bacillus Calmette-Guérin (BCG) therapy for bladder carcinoma. Although hepatitis-associated disseminated BCG was suspected, granulomatous formations were undetectable. The hepatic injury was considered to have resulted from an allergic reaction to BCG therapy because a histopathological assessment revealed enlarged portal areas with eosinophils and neutrophils. The hepatic injury was resolved by prednisolone. This case suggested that hepatic injury associated with BCG therapy might be due to an allergic mechanism unrelated to disseminated BCG disease. A liver biopsy is needed to confirm the histopathological findings of hepatic injury after BCG therapy in order to differentiate allergic hepatic injury from infectious hepatic injury.

Isoniazid and rifampicin co-therapy are the main causes of anti-tuberculosis drug-induced liver injury (ATB-DILI) and acute liver failure, seriously threatening human health. However, its pathophysiology is not fully elucidated. Growing evidences have shown that fibroblast growth factors (FGFs) play a critical role in diverse aspects of liver pathophysiology.

Background: Lung transplantation is a viable lifesaving option for patients with diffuse pulmonary arteriovenous malformations (AVMs). We present a case of diffuse pulmonary AVMs associated with juvenile polyposis and hereditary hemorrhagic telangiectasia (JP-HHT) that was successfully managed by lung transplantation.
Case Presentation: A 19-year-old woman developed severe hypoxemia due to pulmonary AVMs diagnosed at 4Â years of age.

Background: We sought to define whether and how hepatic ischemia/reperfusion (I/R) as manifested by perioperative aspartate aminotransferase (AST) and alanine aminotransaminase (ALT) levels impact long-term outcomes after curative-intent resection of hepatocellular carcinoma (HCC).
Patients And Methods: Intrasplenic injection of HCC cells was used to establish a murine model of HCC recurrence with versus without I/R injury. Patients who underwent curative resection for HCC were identified from a multi-institutional derivative cohort (DC) and separate external validation (VC) cohort.
Rice Straw-Derived Biochar Mitigates Microcystin-LR-Induced Hepatic Histopathological Injury and Oxidative Damage in Male Zebrafish via the Nrf2 Signaling Pathway.

Microcystin-leucine arginine (MC-LR) poses a serious threat to aquatic animals during cyanobacterial blooms. Recently, biochar (BC), derived from rice straw, has emerged as a potent adsorbent for eliminating hazardous contaminants from water. To assess the joint hepatotoxic effects of environmentally relevant concentrations of MC-LR and BC on fish, male adult zebrafish () were sub-chronically co-exposed to varying concentrations of MC-LR (0, 1, 5, and 25 μg/L) and BC (0 and 100 μg/L) in a fully factorial experiment.

This study aimed to investigate the protective effects of vitamin B complex and alpha-lipoic acid (ALA) pre-treatments on hepatic ischemia-reperfusion injury (IRI) in rats, focusing on their potential to enhance antioxidant defense mechanisms and reduce post-ischemic liver damage. Thirty male Wistar albino rats were divided into four groups: sham group (n = 10), IRI group (n = 10), vitamin B group (n = 10), vitamin B + ALA group (n = 10). In the IRI, vitamin B, and vitamin B + ALA groups, the rats underwent 45 min of hepatic ischemia followed by 60 min of reperfusion.
