Key clinical point: Intestinal permeability as well as fecal and plasma metabolomic profiles significantly affected the clinical response to fecal microbial transplantation (FMT) or sham transplantation in patients having peripheral moderate-to-high psoriatic arthritis (PsA) despite receiving methotrexate for ≥3 months.
Major finding: Lactulose-to-mannitol ratio was higher at week 26 (0.027 vs 0.012; P = .013), indicating greater small intestinal permeability; moreover, fecal ( P < .0001) and plasma ( P = .005) metabolomic profiles differed in patients who needed vs did not need treatment intensification after undergoing an FMT or sham transplantation.
Study details: This exploratory study of the FLORA trial included 31 patients who had peripheral moderate-to-high PsA despite ≥3 months of methotrexate treatment and were randomly assigned to undergo either gastroscopic-guided single-donor FMT (n = 15) or sham transplantation (n = 16).
