Innovative Strides: Platelet-rich Plasma Revolutionizing Diabetic Foot Care—A Series of Enlightening Cases

Background: The potential of platelet-rich plasma (PRP) therapy in treating diabetic foot ulcers (DFUs) lies in its elevated growth factor concentration.Clinical studies indicate that PRP expedites the healing of chronic wounds, reduces ulcer size, and shortens recovery time in comparison with standard or alternative treatments.In controlled studies, the application of autologous PRP gel improves the healing percentage without significant side effects.Hence, PRP could be considered an additional treatment for non-healing DFUs, particularly when conventional therapies are ineffective.Aims: To investigate the positive therapeutic outcomes of using PRP in hastening the healing of chronic ulcers.Materials and methods: Patients with chronic DFUs failing standard treatments were considered for PRP.The collected whole blood (WB), with anticoagulants, undergoes a controlled first centrifugation to segregate RBCs, resulting in three layers.For pure PRP, the upper layer and buffy coat are transferred to a sterile tube; for leukocyte-rich PRP, the entire buffy coat is used.The second centrifugation, with adequate "g" force, forms soft pellets at the tube's bottom.After removing platelet-poor plasma (PPP), the pellets are homogenized in the lower one-third to produce PRP.Results: The application of PRP therapy in our patients with chronic DFUs has yielded exceptionally positive outcomes, reflecting a notable and transformative improvement in their overall condition.The observed benefits include a significant acceleration in the healing of chronic ulcers, a marked reduction in ulcer size, and an overall enhancement in therapeutic responses.Conclusion: In conclusion, PRP therapy shows promise in accelerating DFUs healing, supported by growth factors.The presented case series highlights significant advancements in patients with chronic DFUs, reinforcing PRP's efficacy in challenging cases.
