Platelet-rich fibrin and concentrated growth factors as novel platelet concentrates for chronic hard-to-heal skin ulcers: a systematic review and Meta-analysis of randomized controlled trials.

This study aimed to determine superior outcomes of platelet-rich fibrin and concentrated growth factors dressings in chronic hard-to-heal skin ulcers. A search in PubMed, EMBASE, Cochrane Library and CINAHL(EBSCO) was performed for randomized controlled trials comparing platelet-rich fibrin or concentrated growth factors dressings to standard wound care in chronic hard-to-heal skin ulcers. Primary outcome was the number of ulcers completely healed. Secondary outcomes were percentage of ulcers area reduction and complications. Dichotomous and continuous results were pooled in risk difference and mean difference respectively, with a 95% confidence interval (CI). Eight studies with 578 patients were included. The number of ulcers completely healed in platelet-rich fibrin was significantly higher than in control group, during the fourth week of follow-up (risk difference, 0.48; 95% CI, 0.31-0.66; p < .00001) and at the end of follow-up (risk difference, 0.17; 95% CI, 0.08-0.26; p = .0003). The pooled result between concentrated growth factors and control group was inconclusive due to two few studies included. Platelet-rich fibrin is safe and promising to promote healing of chronic hard-to-heal skin ulcers versus standard wound care. Further studies are warranted to evaluate the roles of concentrated growth factors.
