Abstract: Objective To compare the release kinetics of key osteogenic growth factors and inflammatory cytokines in advanced platelet-rich fibrin (A-PRF) between patients with diabetes mellitus (DM) and healthy populations. Methods Participants meeting the inclusion and exclusion criteria were assigned to either the DM group (n=8) or the healthy control group (n=8). Venous blood was centrifuged to prepare A-PRF membranes, and eluates were collected at 15 min, 60 min, 8 h, 1 d, 3 d, 10 d, 14 d, and 21 d post-incubation. The concentrations of platelet-derived growth factor-BB (PDGF-BB), vascular endothelial growth factor (VEGF), transforming growth factor-beta (TGF-β), epidermal growth factor (EGF), tumor necrosis factor-alpha (TNF-α), and interleukin-6 (IL-6) were quantified using enzyme-linked immunosorbent assay (ELISA) and analyzed comparatively. Results (1) Cumulative PDGF-BB release from A-PRF in the DM group was consistently lower than that in healthy controls, with statistically significant differences observed from 15 min onward (P<0.01). (2) VEGF release from A-PRF was significantly reduced in the DM group from day 1 to day 21 compared to controls (P<0.01). (3) No statistically significant difference in cumulative EGF release was observed between the two groups (P>0.05). (4) Cumulative TGF-β release from A-PRF was significantly lower in the DM group from day 1 onward (P<0.05). (5) TNF-α release from A-PRF was significantly higher in the DM group than in healthy controls from 8 h onward (P<0.05). (6) No statistically significant difference in cumulative IL-6 release was observed between the two groups (P>0.05). Conclusion Compared to healthy individuals, DM patients exhibited significantly lower cumulative release of osteogenic growth factors (PDGF-BB, VEGF, TGF-β) from A-PRF and elevated levels of the inflammatory cytokine TNF-α. No significant differences were observed in EGF and IL-6 release.
