Popis: Background:Patients’ first-hand experiences of faecal microbiota transplantation (FMT) performed in a rheumatological care-setting have yet to be elucidated.Objectives:The objectives were to explore participants’ perceptions of being part of an FMT trial thereby identifying potential trial participation effects and enlightening the patient perspective on the outlook for future FMT trials in rheumatic diseases.Methods:In a qualitative study nested within a double-blind, randomised, placebo-controlled trial (RCT) testing FMT as a potential new anti-rheumatic treatment,1 semi-structured telephone interviews were conducted following the trial participants’ final 26-week visit. The RCT was conducted at a Danish rheumatology university outpatient clinic with nationwide inclusion. The qualitative study included ten patients with psoriatic arthritis (PsA) who completed the final 26-week trial visit and were unaware of their treatment allocation (one gastroscopic-guided FMT or sham transplantation into the duodenum), see table 1. Qualitative researchers, who did not take part in the RCT, performed the interviews and the primary analysis. The experiences explored related to the conduct of the RCT and changes in the participants’ everyday life. The analysis was carried out using a thematic approach. There was sufficient repetition of ideas in data to conclude data saturation.Table 1.Characteristics of the participants.CharacteristicTotal(n = 10)Female sex, no.

Renewed hopes for the future in addition to a feeling of enhanced care contributed to significant trial participation effects.2 We identified several factors related to the RCT that may have promoted these effects (figure 1). FMT was deemed acceptable and safe, and all participants supported more research into the field of microbiota-targeted interventions in rheumatic diseases.Figure 1.Factors related to the RCT that may have promoted trial participation effects.Conclusion:Discrepancies between the clinical and the research setting should be considered when discussing the clinical relevance of the results of the RCT. Overall, patients with PsA who have participated in an RCT testing FMT find the treatment acceptable and safe encouraging more research into the field of microbiota-targeted interventions in rheumatic diseases. Further research into the potential beneficial and adverse effects of FMT in addition to exploring the magnitude and mechanisms behind FMT trial participation effects in the rheumatological setting are highly needed.References:[1]Kragsnaes MS, Kjeldsen J, Horn HC, et al.
