Efficacy of allogeneic platelet-rich on healing and regeneration of diabetic foot wounds / 中国输血杂志

ABSTRACT

【Objective】 To investigate the effect of allogeneic platelet-rich on the healing and regeneration of diabetic foot wounds. 【Methods】 A total of 86 patients with diabetic foot ulcer treated in our hospital from January 2019 to June 2020 were selected for this study. They were divided into 2 groups by the random number table method, with 43 patients in each group. The control group was given conventional treatment according to the Guidelines for the Diagnosis and Treatment of Diabetic Foot in China, and the observation group was further treated with platelet-rich gel (APG) from the allogeneic blood bank.The clinical efficacy, general conditions, wound conditions, inflammatory factors, serum levels of transforming growth factor-β1 (TGF-β1), vascular endothelial growth factor (VEGF) and hyaluronic acid (HA) were compared between the two groups. 【Results】 The total effective rate of patients in the observation group was 93.02%, higher than 76.73% in the control group (P0.05). After treatment, hsCRP (2.35±0.50 vs 2.83±0.44) mg/L, TNF-α(3.15±0.82 vs 4.02±1.07) μ g/L and IL-6 (50.82±18.54 vs 72.93±20.25) mg/L in the observation group were lower than those in the control group (P 0.05). After treatment, the levels of TGF-β 1 (17.29±4.09 vs 14.03±3.72) ng/L, VEGF (43.03±14.17 vs 37.04±11.05) and ha (177.96±39.08 vs 151.94±36.17) in the observation group were higher than those in the control group (P<0.05). 【Conclusion】 On the basis of conventional treatment, allogeneic blood bank concentrated platelet APG can effectively improve the curative effect of diabetic foot wound and shorten the wound healing time and hospitalization time. The mechanism may be related to reducing the level of inflammatory factors and increasing TGF-β 1, VEGF and HA.
