Abstract

In chronic wounds, there is a disorder of the regeneration and epithelization process. One of the reasons is the depletion of GF. Platelet-rich plasma for the treatment of chronic wounds is an effective, highly safe, minimally invasive therapy. Objectives of the study are:
1. To evaluate the difference between EGF and VEGF concentrations in PRP before and after activation.
2. To evaluate the difference between EGF, VEGF concentrations in the area of ​​chronic wounds treated with PRP.
The study was conducted on 24 patients with chronic wounds, aged from 18 years old and above, treated (by injection of PRP at wound site) at the National Burns Hospital from 11/2018 to 2/2020. Quantification of EGF and VEGF based on the Elisa principle, using the standard substances EGF/VEGF and antibodies specific to EGF/VEGF.
The results showed that the concentrations of EGF/VEGF in PRP increased after activation; concentrations of EGF and VEGF in wound tissue also increased after 1 week of treatment.
Conclusion: The PRP therapy at a wound site has the effect of stimulating wound healing through increasing EGF and VEGF in chronic wounds.
