Article Abstract
A recent study revealed that d-mannose suppressed immunopathology in mouse models of autoimmune diabetes and airway inflammation and increased the proportion of regulatory T cells (Tregs) in mice. We investigated the effect of d-mannose on liver injury in murine autoimmune hepatitis (AIH) models induced by concanavalin A (ConA) and α-galactosylceramide (GalCer). Mouse models of AIH were created by intraperitoneal injection of GalCer or intravenous injection of ConA. Drinking water was supplemented with d-mannose and biochemically and pathologically examined over time. The administration of d-mannose to AIH model mice significantly reduced liver injury and reduced inflammatory cytokine expression. In addition, Tregs among splenocytes and intrahepatic lymphocytes were significantly increased by the administration of d-mannose. These results indicate that treatment with d-mannose reduced the inflammatory response in the liver and suppressed liver damage by increasing Tregs.

Causal relationship of body mass index with autoimmune liver diseases mediated by circulating cytokines: A Mendelian randomization study.
Medicine (Baltimore)

College of Basic Medical Sciences, Zhejiang Chinese Medical University, Hangzhou, China.
Observational studies suggest associations between elevated body mass index (BMI) and autoimmune liver diseases (AILDs), yet causal evidence remains limited. This Mendelian randomization (MR) study aimed to elucidate the causal role of BMI in AILDs and identify mediating pathways involving 91 circulating cytokines. Utilizing public genome-wide association study data, univariate and multivariate MR analyses were conducted to assess causal relationships between BMI and 3 AILDs.

Background: Autoimmune hepatitis (AIH) is a chronic immune-mediated liver disease with a recognized, but incompletely defined, association with inflammatory bowel disease (IBD). The long-term risk of developing IBD in AIH patients and its influence on hepatic outcomes remain unclear.
Aim: To determine the incidence and risk factors for IBD in a large AIH cohort over a 20-year follow-up and to assess its impact on liver-related complications.
Protective Role of Coffee in Chronic Liver Disease: A Focus on Processing.

Chronic liver disease (CLD) is a leading cause of global morbidity and mortality, necessitating effective preventive strategies. Growing evidence is linking coffee consumption with reduced risk of disease progression in various CLDs, including metabolic dysfunction associated steatotic liver disease (MASLD), alcoholic liver disease, hepatitis B and C, autoimmune hepatitis, and a reduction in the risk of hepatocellular carcinoma development. Coffee, a globally consumed beverage, contains bioactive compounds like caffeine, chlorogenic acids, diterpenes, and polyphenols, which may offer hepatoprotective benefits through anti-inflammatory, antioxidant, and metabolic regulatory effects.

Peliosis hepatis is a rare condition characterized by dilation of the hepatic sinusoids and the presence of multiple blood-filled cystic spaces within the liver parenchyma. It has been associated with a variety of etiologies, including infectious diseases, immunological disorders, malignancy, and certain medications. We report a case of a 24-year-old male who presented with polyarthritis lasting two months.
