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

INTERVENTIONAL
Conditions
Summary
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.
Eligibility
Inclusion Criteria15
- Patients aged at least 18 years

- 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 Criteria14
- 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%)

- History of cancerous or precancerous lesions in the area of intervention
- On active treatment with other local treatment at the site of treatment
- On active treatment with immunosuppressants and/or other drugs contraindicating blood collection
- History of allergy to blood derivatives
- Previous diagnosis of coagulopathies
- Regular and continuous treatment (≥ 3 months) with NSAIDs (with the exception of the use of acetylsalicilic acid)
- Pregnancy or women of chilbearig age not taking effective contraceptive measures. These methods are, according to recommendations of the Clinical Trial Facilitation Group (CTFG) Contraception Working Group (CTFG) (V1.1), the following Hormonal contraception associated with ovulation inhibition, intrauterine decide (IUD), intrauterine hormone-releasing system, bilateral tubal ligation, vasectomy partner, sexual abstinence
- Breastfeeding women
- Treatment with monoclonal antibodies
- Any inabilities to participate in the study

Interventions
Topical application of PRGF will be maintained each time the patient undergoes the conventional treatment. The frequency of conventional treatment will be determined by the health specialist according to the evolution of the ulcer. The treatment will be maintained until complete wound closure or until the end of the follow-up period (6 months).
Conventional treatment (conventional treatment with adequate offloading and metabolic control, +/- antibiotic). The "TIME" dynamic wound closure strategy will be followed, which summarizes the four key points to stimulate the natural healing process: control of non-viable tissue, control of inflammation and infection, control of exudate and stimulation of the edges. After healing, chlorhexidine spray will be applied topically to these patients. The frequency of conventional treatment will be determined by the health specialist according to the evolution of the ulcer. Treatment will be maintained until complete wound closure or until the end of the follow-up period (6 months).
