The Link of Portal-Hypertensive Gastropathy to Anaemia, Systemic Inflammation and Disease Progression in Cirrhosis.

BACKGROUND AND AIMS: Portal-hypertensive gastropathy (PHG) is considered a potential cause of chronic bleeding and anaemia in patients with advanced chronic liver disease (ACLD) and might represent an endoscopic reflection of an impaired gut-liver axis associated with portal hypertension. The clinical significance of PHG in patients with ACLD undergoing routine endoscopies remains understudied.

METHODS

PHG was classified as absent, mild, or severe in prospectively recruited ACLD patients undergoing routine endoscopy (i.e., variceal screening) in the absence of acute bleeding between Q2/2017-Q3/2023. PHG severity was correlated with liver disease severity, systemic inflammation, anaemia, and development of non-variceal bleeding, decompensation or liver-related death during follow-up.

RESULTS

Among 324 patients included in the study, 68 (21%) had no PHG, 190 (58.6%) mild, and 66 (20.4%) severe PHG. Increasing PHG severity was associated with higher MELD (p < 0.001), hepatic venous pressure gradient (HVPG, p < 0.001), presence of varices (p = 0.001), and elevated IL-6 levels (p < 0.001). Iron deficiency anaemia occurred at similar frequencies in patients with mild (24.2%) and severe PHG (31.8%). PHG evaluation was not confounded by the presence of histological gastritis or proton pump inhibitor use. During a median follow-up of 17.6 months, severe PHG was not associated with an increased risk of non-variceal gastrointestinal bleeding, transfusion-dependent anaemia, or bacterial infections. Severe PHG was associated with a higher incidence of hepatic decompensation and liver-related mortality (HR = 1.64; p = 0.015). However, severe PHG was not an independent risk factor for hepatic decompensation and liver-related death (aHR: 1.12; p = 0.727) when adjusted for portal hypertension (HVPG; aHR: 1.07; p = 0.007) and liver dysfunction (MELD; aHR: 1.05; p = 0.123).

CONCLUSION

In stable patients with ACLD undergoing routine endoscopy, the presence and severity of PHG reflect portal hypertension, liver disease severity, and systemic inflammation. However, PHG does not represent an independent risk factor for liver disease progression when adjusted for established markers of portal hypertension and hepatic dysfunction.
