Hypertension and gout: A Mendelian randomization study

Abstract

Abstract Background: Although there is solid epidemiological evidence supporting the connection between hypertension and gout, the causal relationship and direction associated are uncertain, so we aim to research the causal relationship between hypertension and gout. Methods: We conducted a two-sample Mendelian randomization (MR) analysis to assess the causal effect between hypertension (including diastolic blood pressure and systolic blood pressure) and gout (including gout, drug-induced gout, idiopathic gout, unspecified gout, and strictly defined gout) using genome-wide association study statistics. The inverse variance weighting method was used to generate the main results, while sensitivity analyses using MR-Egger, weighted median, Cochran’s Q test, Egger intercept test, and leave-one-out analysis, were performed to assess the stability and reliability of the results. Results: After the screening, we found a causal relationship between diastolic blood pressure and gout, idiopathic gout, unspecified gout, and strictly defined gout, and a causal relationship between systolic blood pressure and gout, idiopathic gout, unspecified gout, and strictly defined gout. Conclusion: It is indicated that the control of hypertension may reduce the risk of gout.
