Autologous Platelet-rich Plasma vs Conventional Dressing in the Management of Chronic Diabetic Foot Ulcers

Introduction. Diabetic foot ulcers (DFUs) are a major complication of diabetes. Recently, considerable progress has been achieved in techniques that promote wound healing. Autologous platelet-rich plasma (PRP) is one such technique that is gaining popularity. Platelet-rich plasma is thought to stimulate wound healing by releasing growth factors essential for healing. Objective. This research aimed to study the efficacy of PRP in managing chronic DFUs. Materials and Methods. Seventy-two patients with chronic DFUs were equally divided into 2 groups. The first group was treated with activated PRP injection and gel on the surface of the ulcer, and the second group was treated with conventional dressing using normal saline to irrigate the wound, followed by coverage with petrolatum gauze and sterile dressing. Results. Both methods of treatment improved healing, but there was a significant increase in healing rate among the PRP group compared with the conventional dressing group (31/36 patients [86.11%] vs 23/36 patients [63.89%]; P =.029). Additionally, the healing duration was shorter in the PRP group than in the conventional dressing group (10.90 weeks +/- 3.40 standard deviation vs 13.48 weeks +/- 3.37, respectively; P =.01). Conclusions. The use of autologous PRP results in a higher rate of wound healing in less time compared with conventional wound care in managing DFUs. Platelet-rich plasma is an effective and promising treatment for chronic DFUs; PRP enables healing in less time. This is expected to positively affect the individual's performance and minimize long-term health care expenditure on foot ulcers.
