Increasing evidence suggests that alterations in the gut-liver axis, including intestinal dysbiosis, increased intestinal permeability, and bacterial translocation, may contribute to liver inflammation and hepatocellular injury. Bacterial components such as lipopolysaccharide (LPS) may reach the portal circulation and activate hepatic immune pathways through receptors including CD14 and Toll-like receptor 4 (TLR4).\n\nThis study aims to investigate the potential role of bacterial translocation in patients with unexplained persistent hypertransaminasemia undergoing liver biopsy. Standard histological evaluation will be integrated with immunohistochemical and molecular analyses of liver biopsy specimens to assess markers associated with bacterial translocation, including bacterial DNA, LPS, and soluble CD14 (sCD14). The study may help clarify the underlying mechanisms of otherwise unexplained hypertransaminasemia and identify potential biomarkers for future clinical use.",[26],"Cryptogenic Hypertransaminasemia",[28,29,30,31],"liver disease","liver cancer","Bacterial translocation","biomarker","NOT_YET_RECRUITING","2026-09-16",{"date":35,"type":36},"2026-09-22","ACTUAL",{"date":38,"type":22},"2026-10-01",{"date":40,"type":22},"2031-10-01",{"name":42,"class":43},"Fondazione Policlinico Universitario Agostino Gemelli IRCCS","OTHER"]
