Targeting <i>Dialister</i>-driven succinate accumulation: A novel strategy for Crohn's disease activity control and recurrence prevention

Crohn's disease (CD) activity and postoperative recurrence significantly affect patients' quality of life, highlighting the need for new treatment and prevention strategies. We read with interest Boronat-Toscano <i>et al</i>'s study on <i>Dialister</i>-driven succinate accumulation in CD. By analyzing the fecal microbiota, circulating succinate levels, and clinical indices using clinical samples, the researchers explored the roles of <i>Dialister</i> and succinate in CD, a previously unaddressed area. They revealed that active CD is characterized by high succinate levels, which are associated with disease severity and inflammatory indicators. The enrichment of <i>Dialister</i>, linked to impaired succinate clearance and postoperative recurrence, offers new insights. The study identified succinate and <i>Dialister</i> as potential therapeutic targets, advancing understanding of CD pathophysiology and paving the way for further investigations. Future studies should involve large, multicenter cohorts for validation, explore <i>Dialister</i>'s strain-specific metabolic mechanisms, and develop treatments targeting the "succinate axis", thus connecting fundamental research with clinical applications.
