Association between proton pump inhibitors and risk of hepatic encephalopathy in patients undergoing transjugular intrahepatic portosystemic shunt: a protocol for a systematic review and meta-analysis

Introduction Hepatic encephalopathy (HE) is a major complication of acute liver failure, cirrhosis and transjugular intrahepatic portosystemic shunt (TIPS) placement. Its clinical manifestations range from mild cognitive deficits to coma. Furthermore, HE is a financial burden to a patient’s family and significantly affects the patient’s quality of life. In clinical practice, proton pump inhibitors (PPIs) are widely used for the treatment of HE. The use of PPIs is associated with an increased risk of post-TIPS HE; however, findings on the risk relationship between PPIs and post-TIPS HE are inconsistent. Therefore, a systematic evaluation of the relationship is needed to further provide valid evidence for the rational use of PPIs in patients who undergo TIPS. Methods and analysis PubMed, Web of Science, Cochrane Library and Embase will be searched extensively for relevant information. Information from 1 July 2023 to 31 July 2023 in these databases will be included. Primary outcomes will be the use of PPIs and incidence of HE after TIPS; secondary outcomes will be survival, dose dependence and adverse events. This meta-analysis will be reported in accordance with the 50 Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020. The risk of bias, heterogeneity and quality of evidence of the included studies will be evaluated prior to the data analysis. All data will be analysed using Review Manager (V.5.4.1) and Stata (V.17.0) statistical software. Eth...
