Proton Pump Inhibitor Use and Risk of Hepatic Encephalopathy: a Multicenter Study
JHEP Reports(2024)
Abstract
Background & AimsData on the association between proton pump inhibitor (PPI) use and hepatic encephalopathy (HE) are conflicting, and data from multicenter studies are scarce. The aim of this study was to dissect the potential association between PPI use and minimal (MHE) and overt HE (OHE).MethodsData from patients with cirrhosis recruited at seven centers across Europe and the US were analyzed. MHE was defined by the Psychometric Hepatic Encephalopathy Score (PHES). PPI use was recorded on the day of testing with PHES. Patients were followed for OHE development and death/liver transplantation (LTx).Results1160 patients with a median MELD of 11 were included (Child-Pugh stages: A 49%/B 39%/C 11%). PPI use was noted in 58% of the patients. Median follow-up time was 18.1 months, during which 230 (20%) developed an OHE episode, and 224 (19%) reached the composite endpoint of death/LTx. In multivariable analyses, PPI use was neither associated with the presence of MHE at baseline nor OHE development during follow-up. These findings were consistent in subgroup analyses of patients with Child-Pugh A or B cirrhosis and after excluding patients with a history of OHE. PPI use was also not associated with a higher risk of OHE, neither in patients with an indication for treatment nor in patients without an indication.ConclusionsPPI use is not associated with a higher risk of HE in patients with liver cirrhosis. On the basis of these findings, a prescription should currently not be prohibited in case of a generally accepted indication.Impact and implicationsData on the association between proton pump inhibitor (PPI) use and hepatic encephalopathy (HE) are conflicting. In this study, PPI use was not associated with a higher risk of minimal HE at baseline or overt HE during follow-up in patients with liver cirrhosis. On the basis of these findings, a prescription of a PPI by a physician should currently not be prohibited in case of a generally accepted indication.
