  • Intensive versus Routine Education on Diabetes Mellitus for Preventing Diabetic Foot Ulcer: A Systematic Review

    Objective To assess the effectiveness of intensive versus routine education on diabetes mellitus for preventing diabetic foot ulcer. Methods We electronically searched CENTRAL (Issue 1, 2013), PubMed (1978-2013), EMbase (1978-2013), VIP (1989-2013) and WanFang Data (1980-2013), hand-searched correlated proceedings and retrieved the references of included studies, for the randomized controlled trials on intensive versus routine education on diabetes mellitus for preventing diabetic foot ulcer all over the world. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data, and assessed the methodological quality of included studies. Then, meta-analysis was performed using RevMan 5.2 software. Results Twelve trials involving 1 841 patients were finally included. The results of meta-analysis showed that: a) the incidence of diabetic foot ulcer in the intensive education group was lower than the routine group, with a significant difference (RR=0.51, 95%CI 0.30 to 0.84, P=0.008); b) two groups were alike in the amputation rate, with no significant difference (OR=0.54, 95%CI 0.17 to 1.67, P=0.28); and c) the score of knowledge on diabetes mellitus was higher in the intensive education group than in the routine education group, with a significant difference (MD=7.32, 95%CI 3.57 to 11.06, P=0.000 1). Conclusion Current evidence shows that: compared with routine education, intensive education could reduce the incidence of diabetic foot ulcer effectively. However, the above conclusion should be verified by conducting more high quality studies.

  • CLINICAL STUDY ON TOPICAL Bismuth Subgallate/Borneol (SuileTM) DRESSING FOR TREATMENT OF DIABETIC FOOT ULCERS

    Objective To evaluate the efficacy and safety of Bismuth Subgallate/Borneol (SuileTM) (BSB) dressing in the treatment of diabetic foot ulcers. Method s A two-center, randomized controlled parallel-group comparison study was conducted. Between September 2005 and November 2006, 35 patients with nonhealing diabetic foot ulcer (Wagner 2-3 grade) were recruited and divided randomly into the test group (BSB group, n=25) and control group (IG group, n=10). There was no significant difference in general data between 2 groups (P gt; 0.05). Based on the comprehensive therapy of diabetic foot, ulcers were topically treated by SuileTM dressing and Intrasite gel in the BSB group and IG group, respectively. The ulcer area was measured once a week. Ulcer bleeding was observed and acceptance of the dressing was inquired each week. Results Of the patients, 22 patients in the BSB group and 8 in the IG group completed the clinical trial. Intention to treat (ITT) analysis indicated that the results were excellent in 19 (76%) cases, good in 3 cases (12%), fair in 1 case (4%), and poor in 2 cases (8%) in the BSB group. In the IG group, the results were excellent in 8 cases (80%) cases, fair in 1 case (10%), and poor in 1 case (10%). Per-protocol (PP) analysis showed that the results were excellent in 19 cases (86%) and good in 3 cases (14%) in the BSB group, and were excellent in 8 cases (100%) in the IG group. The results of ITT and PP analysis all showed no significant difference between 2 groups (P gt; 0.05). The change trend of ulcer areas in the BSB group was similar to that in the IG group. There was no significant difference in the hemostatic effect between 2 groups (P gt; 0.05) and the patients were more likely to accept BSB dressings. Conclusion BSB dressings is an effective, safe, and generally well-tolerated therapy dressing in the treatment of diabetic foot ulcers.

  • A Meta-analysis of Tissue Engineered Skin Improved Wound Closure in Diabetic Foot Ulcers

    Objective To systematically analyze the randomized controlled trials that compare tissue-engineered skin (TES) with conventional treatment for chronic diabetic foot ulcer (DFU) in terms of effectiveness and utilization.Methods We searched the electronic databases (PubMed, Embase, Cochrane Central Register of Controlled Trials, CBMWeb, CNKI, and VIP) in order to compare the efficiency and safety between TES and conventional treatment (CT) in the patients with DFU. In addition, we manually searched reference lists from original studies and review articles.Results Seven trials were included, which were all randomized controlled trials and had a duration of DFU over 6 weeks. There were 880 participants that met inclusion criteria in all studies, and all patients underwent pre-treatment procedures and were treated by TES (human skin equivalents, living skin equivalents or bioengineered skin, such as Graftskin, Dermagraft and Graftjacket) for 12 weeks. All trials had two groups: the treatment group and the control group, but the two trials divided the treatment groups into 3 different dosages and 2 different ulcer allocation subgroups, respectively. Meta-analysis results showed significant differences in the rate of complete wound closure (Plt;0.0001, 95%CI 0.08 to 0.20) and in the occurrence of complications and severe adverse events (P=0.008, 95%CI – 0.06 to – 0.01) between TES treated patients and conventionally treated patients. Conclusion The review shows TES improves completed closure of DFU compared with CT, and it is more effective in reducing side effects.

  • Clinical Effect of Silver Dressings on Diabetic Foot Ulcer Infection

    ObjectiveTo observe the effect of silver dressings on treating diabetic foot ulcer infection. MethodsA total of 105 patients with diabetic foot ulcers treated from May 2012 to April 2014 were randomly divided into two groups:group A and B. Patients in group A were treated with imported silver ion alginate dressing, while group B was treated with domestic nanometer silver dressing. All patients were given basic treatment, and the effect of silver dressing was evaluated by observing bacterial clearance rate and wound healing score. ResultsThere were significant improvement in bacterial clearance rate and wound healing score in both two groups after treatment. The bacterial clearance rate was similar between the two groups (P>0.05). However, the descending trend of wound healing score in group A was significantly more obvious than group B (P<0.01). ConclusionBoth two silver dressings are effective in the treatment of diabetic foot ulcer infection, but the effectiveness of silver ion alginate dressing is superior. Bacterial clearance rate and wound healing score are objective and applicable index to evaluate the treatment effects of silver dressing.

  • Hyperbaric Oxygen Therapy as Adjunctive Treatment for Diabetic Foot Ulcers: A Systematic Review

    ObjectiveTo systematically review the clinical efficacy and safety of hyperbaric oxygen therapy as adjunctive treatment for diabetic foot ulcers. MethodsSuch databases as The Cochrane Library (Issue 1, 2014), PubMed, EMbase, CBM, VIP, CNKI and WanFang Data were searched up to January 2014 for randomized controlled trials (RCTs) about hyperbaric oxygen therapy as adjunctive treatment for diabetic foot ulcers. According to the inclusion and exclusion criteria, two reviewers independently screened literature, extracted data, and assessed methodological quality of included studies. Then, meta-analysis was performed using RevMan 5.2 software. ResultsFourteen RCTs involving 910 patients were included. The results of meta-analysis showed that, hyperbaric oxygen therapy combined with routine therapy was superior to routine therapy alone regarding ulcer healing rates (RR=2.16, 95%CI 1.43 to 3.26, P=0.000 3), incidence of major amputation (RR=0.20, 95%CI 0.10 to 0.38, P < 0.000 01), reduction of ulcer area (MD=1.73, 95%CI 1.34 to 2.11, P < 0.000 01), and improvement of transcutaneous oxygen tension (MD=14.75, 95%CI 2.01 to 27.48, P=0.02). However, no significant difference was found between the two group in minor amputation rates (RR=0.70, 95%CI 0.24 to 2.11, P=0.53). In addition, neither relevant serious adverse reaction nor complications were reported when using hyperbaric oxygen therapy as adjunctive treatment. ConclusionCurrent evidence shows that hyperbaric oxygen therapy as adjunctive treatment could improve ulcer healing and reduce incidence of major amputation.

  • Effects of autologous platelet-rich gel on the treatment of refractory diabetic foot ulcer

    Objective To investigate the effects of autologous platelet-rich gel (APG) combined with intelligent trauma negative-pressure comprehensive therapeutic instrument on patients with refractory diabetic foot ulcer (DFU). Methods A total of 80 patients with refractory DFU treated in the hospital from January 2015 to January 2017 were divided into the trial group (n=40) and the control group (n=40) by the random number table method. The patients in the two groups were given routine treatment, and on the basis, the patients in the control group were treated with the intelligent trauma negative-pressure comprehensive therapeutic instrument while the ones in the trial group were treated with APG combined with intelligent trauma negative-pressure therapeutic instrument alternately. All patients were observed for 12 weeks. The cure rates, healing time and changes of wound volumes in the two groups before treatment and at 2, 4, 8, and 12 weeks after treatment were recorded. Results The total effective rate of treatment in the trial group was higher than that in the control group (87.5% vs. 67.5%, P<0.05). The wound volumes in the two groups at 4, 8 and 12 weeks after treatment were smaller than those before treatment and at 2 weeks after treatment (P<0.05). The wound volumes in the trial group at 4, 8 and 12 weeks after treatment were significantly smaller than those in the control group (P<0.05). The healing times of Wagner Ⅱ and Ⅲ DFU in the trial group were significantly shorter than those in the control group [(24.71±4.29)vs. (33.84±6.09) days, P<0.05; (33.04±5.97)vs. (45.29±7.05) days, P<0.05]. Conclusion Alternate treatment with APG combined with intelligent trauma negative-pressure comprehensive therapeutic instrument for refractory DFU can promote wound healing, shorten wound healing time, and improve the clinical efficacy.

  • Mechanisms of extracorporeal shock wave therapy in promoting healing of diabetic foot ulcer

    Diabetic foot ulcer is one of the severe chronic complications that lead to disability and death of diabetic patients. In order to solve this problem, adjuvant therapy studies of diabetic foot ulcers have increased in recent years. Extracorporeal shock wave therapy is a novel adjuvant therapy that has been approved by the US Food and Drug Administration for diabetic foot ulcers wounds. In this paper, the mechanisms of extracorporeal shock wave therapy for diabetic foot ulcers are described, including wound angiogenesis, wound tissue blood perfusion, nerve regeneration, granulation tissue proliferation, inflammatory response, anti-infection, migration and differentiation of mesenchymal stem cells and endothelial progenitor cells. This study aims to provide a theoretical basis for the clinical application of extracorporeal shock wave therapy in clinical treatment of diabetic foot ulcers.
