Abstract:

Objective

To explore the causal relationship between gastroesophageal reflux disease(GERD) and hepatobiliary-pancreatic diseases.

Methods

Both the exposure factors and outcome events were selected from the European population. The exposure data on GERD were obtained from the genome-wide association studies (GWAS) database, and data on 11 hepatobiliary-pancreatic diseases were obtained from the FinnGen database. The selection criteria for instrumental variables were single nucleotide polymorphisms with P<5×108, r2<0.001, genetic distance of 10,000kb, and F>10. The statistical methods for Mendelian randomization included inverse variance weighting, weighted median method, MR-Egger, weighted mode,and simple model method. Among these, the results from the inverse variance weighting method were taken as the main basis, with other methods used as supplementary evidence and validation, followed by sensitivity analysis.

Results

GERD increases the incidence of acute pancreatitis, cholecystitis, cholelithiasis, chronic pancreatitis, pancreatic malignancy, non-alcoholic fatty liver disease, and primary sclerosing cholangitis, with OR values and 95%CI of 1.431 (1.237-1.656), 1.235 (1.028-1.484), 1.262 (1.169-1.363), 1.481 (1.194-1.838), 1.517 (1.114-2.065), 1.519 (1.205-1.914), 1.524 (1.182-1.965), respectively. Sensitivity analysis showed no horizontal pleiotropy among the data. There is no causal relationship between GERD and benign liver tumors, liver cirrhosis, hepatocellular carcinoma, or cholangiocarcinoma.

Conclusion

GERD increases the risk of certain hepatobiliary-pancreatic diseases, providing new insights for the prevention and treatment of these diseases and contributing to more comprehensive health management.
