■对糖尿病足溃疡(DFU)的短期臭氧治疗研究的可用性有限,即使它是可访问的,它主要包括在长期臭氧治疗期间进行的基本分析。这项研究旨在评估短期臭氧治疗在促进DFU伤口愈合中的功效。
■对89例2型糖尿病合并DFU患者进行回顾性分析。将患者分为臭氧治疗组(n=41)和对照组(n=48)。伤口状况,细菌类型的变化,炎症指标的变化(红细胞沉降率[ESR],C反应蛋白[CRP],和降钙素原[PCT]),血管内皮生长因子(VEGF),细胞因子[白细胞介素6(IL-6)和肿瘤坏死因子-α(TNF-α)],和氧化应激水平(超氧化物歧化酶[SOD],丙二醛[MDA],治疗前和治疗1周后观察总抗氧化能力[T-AOC])。经过12周的随访,伤口愈合率,截肢率,住院日,抗生素的持续时间,再感染率,新溃疡的发生率,再入院率,和再手术率,使用Kaplan-Meier曲线评估累积伤口愈合率。
■治疗1周后,臭氧治疗组显示更高的VEGF,SOD,T-AOC水平与对照组比较(P<0.05),而CRP,PCT,ESR,IL-6,TNF-α,MDA水平和细菌类型均较低(P<0.05)。经12周随访,臭氧治疗组创面愈合率较高(P<0.05)。Kaplan-Meier曲线显示臭氧治疗组伤口累积愈合率较高(P<0.05)。此外,臭氧治疗组住院天数较低,抗生素的持续时间,再感染率,再入院率与对照组比较(P<0.05)。
■短期臭氧疗法通过减少炎症,有效促进DFU的伤口愈合,增加生长因子水平,改善氧化应激状态,缩短愈合时间,改善长期预后。这些发现表明短期臭氧治疗作为DFU的一种有价值的治疗方式的潜力。
The availability of research on short-term ozone therapy for diabetic foot ulcers (DFUs) is limited, and even when it is accessible, it mainly comprises of basic analysis conducted during long-term ozone therapy. This study was to evaluate the efficacy of short-term ozone therapy in promoting wound healing in DFUs.
A retrospective analysis was conducted on 89 patients with type 2 diabetes complicated by DFUs. The patients were divided into two groups: ozone therapy group (n=41) and control group (n=48). Wound condition, change of bacterial types, changes in inflammatory indicators (erythrocyte sedimentation rate [ESR], C-reactive protein [CRP], and procalcitonin [PCT]), vascular endothelial growth factor (VEGF), cytokines [Interleukin 6 (IL-6) and tumor necrosis factor-α(TNF-α)], and oxidative stress levels (superoxide dismutase [SOD], malondialdehyde [MDA], and total antioxidant capacity [T-AOC]) were observed pre-treatment and after 1 week. After a 12-week of follow-up, wound healing rate, amputation rate, inpatient day, duration of antibiotics, reinfection rate, incidence of new ulcers, readmission rate, and reoperation rate, and cumulative wound healing rate using Kaplan-Meier curves were assessed.
After 1 week of treatment, the ozone therapy group showed higher VEGF, SOD, and T-AOC levels compared to the control group (P<0.05), while CRP, PCT, ESR, IL-6, TNF-α, MDA levels and bacterial types were lower (P<0.05). The ozone therapy group had a higher wound healing rate after a 12-week follow-up (P<0.05). Kaplan-Meier curves indicated a higher cumulative wound healing rate in the ozone therapy group (P<0.05). Additionally, the ozone therapy group had lower inpatient day, duration of antibiotics, reinfection rate, and readmission rate compared to the control group (P<0.05).
Short-term ozone therapy is effective in promoting wound healing in DFUs by reducing inflammation, increasing growth factor levels, improving oxidative stress status, shortening healing time, and improving long-term prognosis. These findings suggest the potential of short-term ozone therapy as a valuable treatment modality for DFUs.
