Abstract
OBJECTIVE To evaluate the effectiveness and adverse events of autologous platelet-rich plasma (PRP) in individuals with lower-extremity diabetic ulcers, lower-extremity venous ulcers, and pressure ulcers. PATIENTS AND METHODS We searched multiple databases from database inception to June 11, 2020, for randomized controlled trials and observational studies that compared PRP to any other wound care without PRP in adults with lower-extremity diabetic ulcers, lower-extremity venous ulcers, and pressure ulcers. RESULTS We included 20 randomized controlled trials and five observational studies. Compared with management without PRP, PRP therapy significantly increased complete wound closure in lower-extremity diabetic ulcers (relative risk, 1.20; 95% CI, 1.09 to 1.32, moderate strength of evidence [SOE]), shortened time to complete wound closure, and reduced wound area and depth (low SOE). No significant changes were found in terms of wound infection, amputation, wound recurrence, or hospitalization. In patients with lower-extremity venous ulcers or pressure ulcers, the SOE was insufficient to estimate an effect on critical outcomes, such as complete wound closure or time to complete wound closure. There was no statistically significant difference in adverse events. CONCLUSION Autologous PRP may increase complete wound closure, shorten healing time, and reduce wound size in individuals with lower-extremity diabetic ulcers. The evidence is insufficient to estimate an effect on wound healing in individuals with lower-extremity venous ulcers or pressure ulcers. TRIAL REGISTRATION PROSPERO Identifier: CRD42020172817.

Abstract
SIGNIFICANCE Platelet-rich plasma (PRP) may be a potential drug for treatment of chronic refractory ulcers, which increase the risk of systemic infection and local canceration. However, the efficacy and safety of clinical application of PRP are still controversial. Thus, this study was aimed to assess the efficacy and safety of PRP in patients with chronic ulcers. Recent Advances: For this meta-analysis, Cochrane's Library, MEDLINE, EMBASE, PubMed, and Web of Knowledge databases were searched. Results were pooled using a random-effects model. The primary outcome was the proportion of completely healed chronic ulcers. CRITICAL ISSUES Seventeen randomized controlled trials (RCTs) were included. Compared with the control group, PRP significantly increased the fraction of healed ulcers (pooled RR =1.50; 95% CI 1.20 to 1.87; I2=47.8%). In autologous PRP (APRP) and homologous PRP (HPRP) subgroups, there were statistical differences between the control group vs. treatment subgroup (pooled RR=1.30, 95% CI 1.10 to 1.54, I2=25.7%; pooled RR=3.53, 95% CI 1.94 to 6.43, I2=0.0%, respectively). In terms of percent of chronic ulcers area healed, there was a statistically significant difference between the PRP-treated group vs. the control group (SMD=1.37, 95%CI=0.91 to 1.82, I2=22.1 %). As for PRP safety, there existed a statistically significant difference between the APRP subgroup and the HPRP subgroup, respectively (pooled RR=0.58; 95% CI 0.35 to 0.98; I2=0.0%) and (pooled RR=4.12; 95% CI 1.55 to 10.96; I2=6.8%). FUTURE DIRECTIONS Our findings shows that PRP may be a beneficial treatment of chronic skin ulcers and that APRP may be much safer than HPRP.

Abstract
BACKGROUND Chronic venous leg ulcer reduces the patients' activities and their overall quality of life. Platelet-rich plasma (PRP) was previously investigated as promising less invasive management for leg ulcers. THIS STUDY AIMS To re-assess the efficacy and safety of PRP in the management of chronic leg ulcers due to venous factors. PATIENTS/METHODS RCT enrolled 80 patients who clinically presented with chronic venous leg ulcers. Forty patients were allocated randomly for the treatment with autologous platelet-rich plasma (PRP). Intradermal and subdermal injection of PRP by 27guage syringe weekly, in all edges and in the granular floor of the ulcer for 4-6 sessions. Another 40 patients managed by conventional treatment by compression and dressing for the same period were allocated as Group B. Objective assessment achieved by the percentage of reduction of the size of the ulcer area, rate of healing, incidence of recurrence, and if side effects have been reported. RESULTS PRP therapy showed better results and high p value significance when compared to conventional therapy. CONCLUSION This study shows that PRP is effective and significant in promoting the wound healing process in chronic leg venous ulcers. PRP is simple, safe, and has a short learning curve technique.

Abstract
OBJECTIVE The current study assesses the effects of platelet-rich plasma-fibrin glue (PRP-FG) dressing along with oral vitamin E and C on wound healing and biochemical markers in patients with non-healing diabetic foot ulcers (non-healing DFU). METHODS This randomized, double-blind, placebo-controlled trial was performed on twenty-five patients with non-healing DFU. Patients were treated with PRP-FG dressing plus oral vitamin E and C (intervention group) or PRP-FG dressing plus placebo (control group) for eight weeks. RESULTS Eight weeks after treatment, six wounds in the intervention group and two wounds in the control group were completely closed, and also wound size significantly reduced in both intervention (-9.7 ± 6.9 cm(2), p = 0.002), and control (-5.6 ± 5.4 cm(2), p = 0.003) groups. This reduction in wound size was significantly greater in the intervention group compared to the control group (p = 0.019). Also, a significant decrease in prooxidant-antioxidant balance (PAB) index, ESR, and hs-CRP were observed in the intervention group compared to the control group (p < 0.05). CONCLUSION Results of this trial showed that PRP-FG dressing along with oral vitamin E and C could be used to increase wound healing in patients with non-healing DFU by enhancing the wound healing process and reducing oxidative stress. TRIAL REGISTRATION This trial is registered at ClinicalTrials.gov (CT.gov identifier: NCT04315909).

Abstract
BACKGROUND AND AIMS Diabetic foot ulcers (DFUs) are among challenging hurdles both for the patient and the physician. There is a recent trend toward finding novel and clinically efficient modalities to treat this potentially hazardous complication of diabetes mellitus in a timely manner. Herein, we aim to appraise the efficacy of platelet-rich plasma (PRP) in healing of clean DFUs. METHODS 90 patients with clean DFUs consisting of 56 (62.2%) males and 34 (37.8%) females with mean age (±standard deviation) of 56.52 (±7.14) years were enrolled in this study between June 2017 and December 2018. They were randomly allocated into control group (47 patients who received conventional dressing along with silver sulfadiazine ointment twice daily), and case group (43 patients who received PRP gel twice weekly for 3 weeks). All the patients were followed up for 6 months. RESULTS Our study showed that PRP significantly increased the healing rate of DFUs regardless of the age (p-value: 0.0), gender (p-value: 0.0), or smoking (p-value: 0.0) and blood pressure (p-value: 0.0) status of patients, but it did not have a significant impact on the need for amputation (p-value: 0.11), level of amputation (p-value: 0.16), or the need for further treatments such as graft or angioplasty (p-value: 0.52). CONCLUSION Regardless of the age, gender, or smoking and blood pressure status of patients, PRP can be efficiently used in diabetic patients to accelerate the healing rate of foot ulcers.

Yuvasri G, Rai R
Indian dermatology online journal. 2020;11(1):58-61
Abstract
Background: Chronic venous leg ulcers are difficult to treat and recurrences are common. Among various modalities of treatment, platelet-rich fibrin (PRF) has shown promising results in ulcer healing by providing necessary growth factors. Unna's paste dressing has also proven to enhance wound healing. Aim: The aim of this study is to compare the efficacy of autologous PRF versus Unna's paste dressing in chronic venous leg ulcer patients and to compare the mean reduction in ulcer area at the end of 4 weeks. Materials and Methods: Twenty patients with chronic venous leg ulcers were randomly divided into two groups. Group 1: Patients received PRF dressing which was repeated every week for 4 weeks. Group 2: Patients received Unna's paste dressing once a week for 4 weeks. The ulcer size was assessed with the help of photographs, and ulcer area was measured. Results: The mean reduction in the area of the ulcer size in the PRF group was 86.03% and in the Unna's paste group was 71.97%, which was not statistically significant with a P value of 0.223. Conclusion: We conclude that though there was no statistical significance between the groups, PRF showed a significant reduction in ulcer size.

Abstract
Our aim was to compare the efficacy and safety of platelet-rich plasma (PRP) application versus PRP injection for chronic venous leg ulcer (VLU) healing compared with compression therapy as a control. From July 2018 to December 2019, 90 chronic VLU patients were randomly assigned to PRP dressings (n = 30), local PRP injections (n = 30), and compression therapy alone (n = 30). Standard compression accompanied both PRP groups. The main endpoints were ulcer healing and area reduction within 3, 6, and 12 months. Complications and ulcer recurrence were also recorded. The study included 72 (80.0%) males and 18 (20.0%) females aged 22 to 66 years, having VLUs for 1 to 11 years. PRP injection promoted healing (24/30, 80%) more than PRP application (20/30, 66.7%) and compression (14/30, 46.7%), P = .007. Healing time was significantly shorter after PRP injection compared with the other two groups. A greater area reduction was observed after PRP injection compared with compression at all follow-up visits, P = .013, .002, and < .001, and compared with PRP application only at 3 months post-treatment, P = .016. Recurrence and complications were comparable among the groups. PRP injection enhances the healing of chronic venous ulcers more than each of PRP application and compression therapy. All had comparable recurrence and safety.

Dermatol Ther. 2020
Abstract
Various management options were tried for Chronic venous leg ulcers (VLUs) with no satisfactory results. Platelet-rich plasma (PRP) is promising in enhancing chronic wound healing by releasing various growth factors. We evaluated the safety and efficacy of topical platelet gel (PG) versus PRP injection in treatment of venous leg ulcers. 20 patients were treated with topical PG (group I), 20 patients received PRP injection (group II) and 20 patients were treated with saline dressing and compression as controls (group III) weekly for 6 weeks. Ulcer improvement was evaluated by pressure ulcer scale for healing (PUSH). Histopathological evaluation and immunohistochemical staining using anti-CD34 were performed before and after treatment. There was significant improvement in PUSH score in group (I) and group (II) compared to group (III) (P-value:0.001). However, there was no statistically significant difference in improvement between group I and II (P-value = 0.83). However, topical PG was more effective in diabetics and PRP was more effective in long standing fibrosed ulcers. Histopathology showed reduction of the inflammatory cells infiltrates and well-formed granulation tissue with no difference in immunostaining. So, both topical PG and PRP injection were effective, low cost and safe procedures in enhancing healing of chronic VLUs. This article is protected by copyright. All rights reserved.

Abstract
OBJECTIVE To examine the potential efficacy and safety of autologous platelet-rich plasma (PRP) in comparison with the conventional treatment (standard care, SoC) for the treatment of leg ulcers in patients with chronic venous insufficiency, in a primary health-care setting. METHOD A Phase I-II, open-label, parallel-group, multicentre, randomised pilot study was conducted. The outcome variables at baseline and at weeks five and nine included reduction in the ulcer area, Chronic Venous Insufficiency Quality of Life Questionnaire score, cost of the treatment for up to nine weeks and average weekly cure rate. RESULTS A total of eight patients, each with at least a six-month history of venous leg ulcer (VLUs), were included in the study. A total of 12 ulcers were treated with either autologous PRP or standard SoC. Patients treated with PRP required wound care only once per week. In the SoC group, patients required intervention 2-3 times per week. A reduction in the mean ulcer size in the PRP group was 3.9cm(2) compared with the SoC group at 3.2cm (2) , although the sample size was insufficient to reach statistical significance. Improvement in quality of life (QoL) score was observed in the patients in the PRP group. CONCLUSION This study offers proof-of-concept of the feasibility and safety of PRP treatment to inform larger clinical trials in patients with VLUs. Our preliminary results suggest that PRP delivers a safe and effective treatment for VLU care that can be implemented in primary health-care settings.

Somani A, Rai R
Journal of Cutaneous and Aesthetic Surgery. 2017;10((1)):8-12.
Abstract
BACKGROUND Venous leg ulcer is a chronic condition, and various treatment modalities are available. Platelet-rich fibrin (PRF) is one of the newer modalities and it contains fibroblast growth factor (GF), vascular endothelial GF, angiopoitin and platelet-derived GF which enhances the wound healing. Hence, we conducted a randomised controlled trial to compare the efficacy of PRF versus saline dressing in chronic venous leg ulcers. AIM: This study aims to compare the efficacy of autologous PRF with saline dressing in patients with chronic venous leg ulcer and to compare the mean reduction in ulcer area at the end of 4 weeks. MATERIALS AND METHODS Fifteen patients with chronic venous leg ulcers of >6 months duration having an ulcer area of 1 cm x 1 cm to 5 cm x 5 cm were taken into the study and were randomly divided into two groups. Group 1: Patients received PRF dressing. Ten millilitres of patient's blood was taken and centrifuged at 3000 rpm for 15 min. A fibrin clot obtained in the middle of the tube was removed and used for dressing over the wound surface. It was repeated every week for 4 weeks. Group 2: Patients received saline dressings once a week for 4 weeks. The assessment of the ulcer size was done with the help of photographs, and ulcer area was measured. RESULTS The mean reduction in the area of the ulcer size in PRF group was 85.51%, and the mean reduction in the area of the ulcer size in Saline group was 42.74% which was statistically significant with a P < 0.001 and t = 4.11. CONCLUSION We conclude that PRF dressing can be used as it is effective, inexpensive, safe and an outpatient procedure.
