Decompression of portal hypertension by transjugular intrahepatic portosystemic shunt reverses markers of gut barrier dysfunction and cirrhosis-associated immune dysfunction

The authors investigate whether portal hypertension (PH) is a key factor driving cirrhosis-associated immune dysfunction (CAID) and if its reduction through transjugular intrahepatic portosystemic shunt (TIPS) can reverse this dysfunction. Their findings indicate that TIPS significantly decreases markers of gut barrier dysfunction, inflammation, and immune activation in patients with decompensated cirrhosis, suggesting that PH plays a central role in CAID. The study concludes that alleviating PH restores immune homeostasis and gut barrier integrity, ultimately improving patient outcomes.
