Abstract[Aim] To assess clinical healing in patients with perianal Crohn’s disease with local intrafistular injection of autologous platelet-rich plasma.
[Method] The pilot study was conducted at a single centre between January 2013 and December 2015. Autologous platelet-rich plasma was prepared in platelet-rich and platelet-poor fractions for local intrafistular injection in patients with proven, established perianal Crohn’s disease. Patients were permitted biological therapies, and the Perianal Crohn’s Disease Activity Index was recorded. Patients were followed for 48 weeks for clinical signs of healing (complete, partial or non-healing), monitoring fistula drainage, closure and epithelialization.
[Results] The study included 29 patients (19 males; mean age 38 ± 12.8 years) with four exclusions in the operating room because surgery was not indicated and four lost to follow-up. Five adverse events were recorded, with two requiring the drainage of abscess collections. Of the 21 patients assessable at 24 weeks, there was complete healing, partial healing and non-healing in 7 (33.3%), 8 (38.1%) and 6 (28.6%) patients, respectively. By 48 weeks, there was complete healing, partial healing and non-healing in 6 (40%), 6 (40%) and 3 (20%) patients, respectively, with a reduction in the number of visible external fistula openings at both time points (P = 0.021). By the end of the study, there was a higher trend of healing if biological therapies were continued (85.7% with biologics vs. 75% without, P = 0.527), but there were no statistically significant differences and no differences in the Perianal Crohn’s Disease Activity Index.
[Conclusion]Autologous platelet-rich plasma is safe in patients with perianal Crohn’s disease, with an acceptable healing rate over a medium-term follow-up, particularly if biological therapies are used concomitantly.
