Summary

This trial is testing whether proton pump inhibitors increase the risk of hepatic encephalopathy after transjugular intrahepatic portosystemic shunt creation. Patients will be assessed for symptoms and given tests at two time points. Stool samples will also be collected to allow characterization of the gastrointestinal tract microbiome.

Who is the study for?
This trial is for adults 18 or older who are already taking proton pump inhibitors (PPIs) and will undergo a TIPS procedure as part of their usual care. They must be willing to follow the study rules and be available for its duration. People can't join if they're pregnant, have severe esophagitis or ulcers, need PPIs after certain esophageal procedures, have Zollinger-Ellison syndrome, or an active Helicobacter pylori infection.
What is being tested?
The trial aims to see if stopping PPIs reduces brain dysfunction (hepatic encephalopathy) after a TIPS procedure. Participants are randomly chosen to either stop or continue their PPI medication. Their brain function and quality of life are measured before and about four weeks after the TIPS procedure.
What are the potential side effects?
While not directly related to side effects from medications, participants may experience changes in digestive symptoms due to altering their PPI therapy. Additionally, there might be variations in gut bacteria which could potentially affect overall health.
