Summary
Topical platelet gel (PG) therapy, derived from activated platelets and cryoprecipitate, enhances wound healing by supplying essential growth factors. This hemotherapy shows promise in reducing wound size and improving granulation tissue formation in patients with cutaneous ulcers.
Area of Science:
- Regenerative Medicine
- Wound Healing Research
- Biotechnology
Background:
- Wound healing involves complex immune responses and growth factor regulation.
- Platelets are crucial for wound repair, releasing growth factors like PDGF, TGF-beta, and VEGF.
- Altered growth factor activity is implicated in impaired wound healing.
Purpose of the Study:
- To evaluate the efficacy of topical platelet gel (PG) as an adjuvant therapy for cutaneous ulcers.
- To assess the impact of PG on wound healing parameters including size, granulation, and infection.
- To investigate the clinical response to hemotherapy using autologous or homologous PG.
Main Methods:
- A multicomponent apheresis procedure was used to obtain platelet-rich plasma and cryoprecipitate.
- Manual processing in a sterile environment was employed for platelet gel activation.
- A quality control program monitored each step of gel synthesis.
- Therapeutic protocol involved weekly topical application of PG to cutaneous ulcers.
Main Results:
- Twenty-four patients with cutaneous ulcers of various etiologies were enrolled.
- Complete wound healing was observed in 9 patients, with 2 requiring skin grafts.
- Partial response was noted in 9 patients, while 4 discontinued treatment.
- All patients experienced increased granulation tissue formation and reduced pain following PG application.
Conclusions:
- Topical hemotherapy with platelet gel can be a valuable adjuvant in managing cutaneous ulcers.
- PG application promotes granulation tissue formation and aids in wound bed preparation.
- This therapy offers a potential method to enhance the healing process for chronic or difficult-to-treat ulcers.
