The human gut microbiome has been suggested to be linked with the risk of developing sepsis, a life-threatening medical emergency. However, it remains unclear whether the gut microbiome is an independent predictor of long-term sepsis risk in the general adult population. Here, we investigated for the first time the prospective association between the gut microbiome and incident sepsis in the general population. The study sample (FINRISK) consisted of 6,372 individuals who underwent fecal sampling in 2002 and were followed for incident sepsis. We used multivariable-adjusted models to study the associations of microbial alpha-diversity, beta-diversity, taxa, butyrate producers, and predicted pathways with incident sepsis. Two hundred and forty participants developed sepsis over a follow-up of 19.8 years. A 1-SD increase in Faecalibacterium prausnitzii_C_71351 abundance was associated with 21% (95% CI, 10%–30%; FDR = 0.03) lower risk of sepsis. Higher abundances of six other species were associated with higher sepsis risk (FDR < 0.05 for all). Five of these species were positively associated with C-reactive protein. The species-sepsis associations were consistent across various subgroups. Moreover, in an independent validation cohort of 4,248 individuals, we found a similar association between Faecalibacterium and a lower risk of future sepsis. Additionally, overall pathways related to carbohydrate degradation, energy production, and sulfur metabolism were positively linked to incident sepsis. We did not detect any associations of alpha-diversity, beta-diversity, or butyrate producers with incident sepsis. Future studies should investigate the causality of these associations and the mechanisms by which the identified species may influence sepsis development.
