Recent research has emphasized a robust correlation between the immune response and gout. Nevertheless, it is still uncertain if this connection is causative. Hence, the objective of this study was to investigate the causal relationship between immune cells and gout, while also analyzing the role of the plasma metabolome as metabolic mediators in this biological process.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>This study explored the causal link between different subtypes of immune cells and gout using two\u2010sample Mendelian randomization (MR). To confirm the reliability of the findings, reverse MR analysis, steiger test and sensitivity tests were conducted.

Reverse MR analysis and sensitivity tests demonstrated the reliability of the MR results. In addition, we found that Tetradecadienedioate (C14:2\u2010DC) played a partially mediating role in the CD4 on activated CD4 regulatory T cell and gout pathways, with a mediating proportion of 13.16%, (95% CI\u2009=\u20090.65%\u201325.67%, <jats:italic>p<\/jats:italic>\u2009=\u20090.034).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The objective of our research was to investigate the possible causative connection between immune cells and gout. Our findings indicate that certain plasma metabolites may play a role in mediating this association. This study offers novel insights and sources of information that may contribute to the early detection and proactive measures to avoid gout in the
