Abstract
BACKGROUND Recent years, many studies have reported that autologous platelet-rich gel (APG) is an effective adjunctive method to promote chronic cutaneous ulcers in diabetics. The aim of the present study was to explore the efficacy and safety of APG for the topical treatment of diabetic chronic cutaneous ulcers. METHODS The Chinese CBM, CNKI, VIP, Wanfang databases, Cochrane Library databases, EBSCOhost, Embase and PubMed on October 18, 2017 were systematically searched. The fixed/random-effect models were used to calculate the risk ratio (RR)/odds ratio (OR)/mean difference (MD) with the 95% confidence interval (95%CI) as the effect analysis statistics. Subgroup analyses were conducted according to the Diabetic Foot Wagner Classification. RESULTS Fifteen RCTs with 829 patients were eligible for the present analysis. Compared with standard care/conventional treatment, APG significantly improved the healing rate (RR=1.39, 95% CI 1.29 to 1.50, P < 0.00001), shortened the healing time (MD= -9.18, 95% CI -11.32 to -7.05, P < 0.00001), reduced the incidence of infection (OR= 0.34, 95% CI 0.15 to 0.77, P = 0.009). CONCLUSIONS Current evidence suggests that APG is effective and safe, and it's probable to be used as an adjuvant treatment for diabetic ulcers, especially for the chronic refractory ulcers. But more RCTs with good design and high quality are needed before it can be implemented widely.
