Allogeneic vs Autologous PRP for Diabetic Wounds in Renal Dysfunction: a Randomized Controlled Trial

Phase 4

Not yet recruiting

• Conditions: Diabetic Wounds; Platelet Rich Plasma; Allogeneic Blood Transfusions; Renal Dysfunction
• Interventions: Drug: autologous platelet plasma; Drug: allogeneic platelet plasma

• Registration Number: NCT07020559
• Lead Sponsor: Peking University Third Hospital

Brief Summary

Diabetic wounds are difficult to heal. Autologous platelets in diabetic patients with renal insufficiency have poor function. Allogeneic platelet plasma has a promising application prospect. Comparing the efficacy and safety differences between allogeneic platelet plasma and autologous platelet plasma is of significant importance and value for the clinical application.

Detailed Description

This study is a single-center, randomized, parallel control, superior trial. Fifty-six renal dysfunction patients with diabetic-related wound after wound bed preparation will be randomly assigned to the autologous platelet plasma group and allogeneic platelet plasma group in a 1:1 ratio. The primary outcome is the wound healing rate at 4 weeks (Stitches removal). The secondary outcomes include the wound healing rates at 3, 6, and 8 weeks, healing time, post-operative wound infection, 7-day, 2-, 3-, 4-, 6-, 8-week pain relief progression assessed by Visual Analog Scale, incidence of mortality, reoperation, and adverse events during the follow-up period.
