Key clinical point: Higher relative abundance of gut microbiota belonging to family Rikenellaceae and an unidentified metabolite X-11538 were associated with a reduced risk for psoriatic arthritis (PsA), highlighting the potential of gut microbiota taxa and metabolites as biomarkers for treatment and prevention of PsA.
Major finding: Adjusted multivariable Mendelian randomization analysis showed that a higher relative abundance of microbiota belonging to the family Rikenellaceae (odds ratio [OR] 0.5; 95% CI 0.320-0.780) and elevated serum levels of X-11538 (OR 0.448; 95% CI 0.244-0.821) were causally associated with a reduced risk for PsA.
Study details: This Mendelian randomization study included summary level data of gut microbiota taxa (n = 18,340), PsA (n = 339,050), and metabolites (n = 7824) from participants included in the MiBioGen consortium, FinnGen Biobank, and TwinsUK and KORA cohorts, respectively.
Disclosures: This study did not receive any funding. The authors declared no conflicts of interest.
