Efficacy of Plasma Rich in Growth Factors (PRGF) in the Treatment of Foot Ulcers in Diabetic Patients With Peripheral Arterial Disease

Randomized Clinical Trial, Controlled With Conventional Treatment to Evaluate the Efficacy of Plasma Rich in Growth Factors (PRGF) in the Treatment of Foot Ulcers in Diabetic Patients With Peripheral Arterial Disease

This study is a randomized clinical trial that compares the effectiveness of Plasma Rich in Growth Factors (PRGF) with conventional treatment for healing foot ulcers in diabetic patients who also have peripheral arterial disease. The goal is to assess how well PRGF promotes healing over a six-month period.

Inclusion Criteria:

• Patients aged at least 18 years
• Diagnosis of type 1 or 2 diabetes
• Presence of one or more ulcers below the malleoli
• Ulcer size ranging from 1 to 25 cm2
• Peripheral Arterial Disease (PAD)
• Meet at least 2 of the following crieria:
• Absence of peripheral pulses at any level on physical examination of lower extremities
• Ankle pressure of 50-90 mmHg
• Finger pressure 30-70 mmHg
• Ankle-branchial index (ABI) 0.5-0.9
• Finger-arm index (FIBI) 0.3-0.7
• Transcutaneous oxygen pressure (TcPO2) 30-59 mmHg
• Degree of infection of the lesion on IDSA/IWGDF scale not greater than 1
• Availability of observation during the study period
• Properly completed patient informed consent

Exclusion Criteria:

• Ulcers grade 3 or higher
• Positive markers for HCV, AfHBs, HIV-I/II or TP
• Diabetes mellitus with poor metabolic control (evidence of glycosylated hemoglobin >9%)
