Implication

Systematic review of Mendelian randomization studies links gut microbiota, particularly methanogens and Bacteroidales, to immune thrombocytopenia risk.

Key Points

This review examines the causal relationships between gut microbiota and immune thrombocytopenia using Mendelian randomization.
Systematic search of PubMed, Embase, and Web of Science for Mendelian randomization studies
Focus on studies treating gut taxa as exposures and immune thrombocytopenia as the outcome
Narrative synthesis of findings due to heterogeneity in taxonomic depth and analytic methods.
Five Mendelian randomization studies involving over 600,000 participants were reviewed
Identified high-risk gut microbes including Alcaligenaceae and methanogens
Confirmed protective role of Bacteroidales S24-7 with an odds ratio of 0.46.
