Brief Summary:
Hepatic encephalopathy (HE) commonly occurs after transjugular intrahepatic portosystemic shunt (TIPS). Ursodeoxycholic acid (UDCA) has been reported to alleviate neurodegenerative disease recently. This open-label multicenter randomized controlled trial tests whether adding UDCA (13-15 mg/kg/day) to standard lactulose prophylaxis reduces the incidence of overt HE (OHE; West Haven grade II-IV) after TIPS, compared with lactulose alone. The regimen starts within 72 hours before TIPS and continues for 3 months. The trial aims to evaluate the effect of UDCA in reducing the incidence of post-TIPS OHE.
Detailed Description:
Post-TIPS OHE occurs in 35-50% of patients and worsens quality of life and resource use. Existing guidance consistently recommends lactulose as the backbone therapy for HE and for secondary prophylaxis, titrated to 2-3 soft stools/day; however, evidence for primary prophylaxis after TIPS has been limited and heterogeneous, and consensus varies across documents. Hydrophilic bile acids, especially ursodeoxycholic acid (UDCA), have demonstrated important anti-apoptotic and neuroprotective activities in clinical practice. Published experimental and clinical evidence suggests its potential therapeutic use as a disease-modifier in neurodegenerative and metabolic brain diseases. This trial evaluates whether bile-acid modulation with UDCA at standard hepatology dosing (13-15 mg/kg/day) combined with lactulose reduces early post-TIPS OHE. The protocol uses stratified randomization, prespecified outcome adjudication (West Haven), and intention-to-treat analysis. Key secondary endpoints include mortality, transplant-free survival, minimal HE tests (PHES, Stroop test), frailty, quality of life, and bile-acid/metabolomic profiling in optional sub-studies.
