Causal relationships among gut microbiota, blood metabolites, and urticaria in East Asians: A Mendelian randomization study.

This study has delineated specific GM taxa and blood metabolites that hold causal relevance to urticaria in East Asian populations. Notably, arabinogalactan degradation potentially mitigates urticaria risk via reducing FPG concentrations, offering genetic evidence to support therapeutic strategies targeting GM modulation and glucose regulation.
