The Effect of Treatment With Umbilical Cord Blood Platelet Lysate on Diabetic Foot Ulcers

The Effect of Treatment With Umbilical Cord Blood Platelet Lysate on Diabetic Foot Ulcers:a Randomized Controlled Trial

Application of autologous Platelet Rich Plasma (PRP) has been a major breakthrough for the treatment of diabetic foot ulcers, as it provides the necessary growth factors which enhance tissue healing. Human umbilical cord blood platelet lysate (UCB-PL) contains a supraphysiological concentration of growth factors. The aim of the study is to evaluate the efficacy of umbilical cord blood platelet lysate (UCB-PL) gel for the treatment of diabetic foot ulcer.

110 patients with diabetic foot ulcer will be randomized to receive UCB-PL gel or regular dressing with normal saline. The diabetic foot ulcers will be first debrided to remove any necrotic and infected tissues or hyperkeratotic skin. Afterward, the wound area will be cleaned thoroughly with normal saline. Ulcer length, width and surface will be measured before any study procedure. The UCB-PL gel in the treatment group and the dressing with normal saline in the control group will be applied in the ulcer, and then a few layers of sterile gauze, and non-compressible bandage will be used to cover the wound/ulcer area. This will be repeated every three days for one month. After the fist one month of treatment, the patients will be followed up for a period of 20 weeks post-treatment. Care and management efforts will be provided at each visit included cleansing and assessing of the wound, obtaining an interim wound history, including information regarding adverse events, concomitant medications and other aspects of care since the last visit. Ulcers will be photographed at two weeks, at four weeks, at two months, at four months and at six months.

A Umbilical cord blood platelel lysate gel will be applied in diabetic foot ulcer every three days for one month.

The control group will receive the clinical standard of care; removable of any necrotic, hyperkeratotic and infected tissue, cleansing of the wound with normal saline and covering of the ulcer with dressing with normal saline and then with a few layers of sterile gauze, and non-compressible bandage.

For the treatment group, a gel from Umbilical cord blood platelel lysat will be applied in the ulcer, and then a few layers of sterile gauze, and non-compressible bandage will be used to cover the wound/ulcer area.

Primary endpoint was to investigate the efficacy of UCB-PL in ulcer healing by assessing the change in ulcer size over the six months follow-up by using the imito-measure application.
