富血小板凝胶是近年来新出现的辅助治疗糖尿病足溃疡(DFU)的方法之一.局部应用富血小板凝胶治疗DFU可有效改善DFU的难愈合性并提高溃疡愈合率,且无明显不良反应发生;也可降低截肢率,且没有增加医疗总费用.富血小板凝胶治疗DFU的作用机制可能与其中富含的生长因子、细胞因子和白细胞等有关,还可能与凝胶超微结构、溃疡中基质金属蛋白酶的变化有关. 相似文献

Aims/hypothesis Large clinical studies describing the typical clinical presentation of diabetic foot ulcers are limited and most studies were
performed in single centres with the possibility of selection of specific subgroups. The aim of this study was to investigate
the characteristics of diabetic patients with a foot ulcer in 14 European hospitals in ten countries.
Methods The study population included 1,229 consecutive patients presenting with a new foot ulcer between 1 September 2003 and 1 October
2004. Standardised data on patient characteristics, as well as foot and ulcer characteristics, were obtained. Foot disease
was categorised into four stages according to the presence or absence of peripheral arterial disease (PAD) and infection:
A: PAD −, infection −; B: PAD −, infection +; C: PAD +, infection −; D: PAD +, infection +.
Results PAD was diagnosed in 49% of the subjects, infection in 58%. The majority of ulcers (52%) were located on the non-plantar surface
of the foot. With regard to severity, 24% had stage A, 27% had stage B, 18% had stage C and 31% had stage D foot disease.
Patients in the latter group had a distinct profile: they were older, had more non-plantar ulcers, greater tissue loss and
more serious comorbidity.
Conclusions/interpretation According to our results in this European cohort, the severity of diabetic foot ulcers at presentation is greater than previously
reported, as one-third had both PAD and infection. Non-plantar foot ulcers were more common than plantar ulcers, especially
in patients with severe disease, and serious comorbidity increased significantly with increasing severity of foot disease.
Further research is needed to obtain insight into the clinical outcome of these patients. 相似文献

The Center for Disease Control (CDC) estimates that 29 million Americans have diabetes, and 70% of diabetic patients develop diabetic peripheral neuropathy [1,2]. Up to 27% of the direct medical cost of diabetes may be attributed to DPN [3]. A 2013 article from the American Diabetes Association reported a $176 billion direct medical cost of diabetes in 2012 [4]. DPN patients often suffer from shooting and burning pain in their distal limbs and a severe loss of sensation. Diabetic foot ulcers, infections, and amputations may follow. Currently available treatments: tricyclic antidepressants, anticonvulsants such as gabapentin and pregabalin, serotonin and norepinephrine reuptake inhibitor, duloxetine, topical 5% lidocaine (applied to the most painful area) can manage painful symptoms but do not address the underlying pathologies of DPN and diabetic wound ulcers. A combination of pain-reducing medications can provide relief when individual medications fail, and opioids such as tramadol and oxycodone may be administered with these medications to reduce pain [5]. Due to the prevalence of diabetes, DPN, and diabetic foot ulcers, and because of the lack of available effective treatments to directly address the pathology contributing to these conditions, novel treatments are being sought. Our hypothesis is that a deficiency of nitric oxide synthase in diabetic patients leads to a lack of vascularization of the peripheral nerves, which causes DPN; and this could be treated with vasodilators such as nitric oxide. In this paper, the mechanisms of DPN are reviewed and analyzed to elucidate the potential of a transdermal nitric oxide application for the treatment of DPN and diabetic wound ulcers by increasing vasodilation. 相似文献

Diabetic complications such as poor circulation and nerve damage can result in loss of sensation and slower wound healing in the lower extremities. The possibility of malignancy arising in association with chronic osteomyelitis in the diabetic foot should also be considered. 相似文献

Neuropathy, mechanical stress, and macrovascular disease are involved in the pathogenesis of diabetic foot ulceration. Implicit in the development of gangrene and ulceration is the recognition that these factors interact with the microcirculation, resulting in the failure of skin capillary flow to meet nutritive requirements. There is little evidence to associate structural microangiopathy with foot microcirculatory failure. Significant functional abnormalities of the microcirculation have been defined. In accord with the haemodynamic hypothesis early hyperaemia and capillary hypertension promote more sinister late functional abnormalities with increasing duration of diabetes. These late functional abnormalities include loss of autoregulation and reduced hyperaemic responses which interact with loss of neurogenic flow regulation, disturbed endothelial function, and abnormal rheology to produce the familiar clinical picture of the diabetic foot. Ischaemia secondary to multi-segment arterial disease induces additional abnormalities of microcirculatory function which are superimposed on the pre-existing diabetic microvascular structural and functional microangiopathy. 相似文献

Aims/hypothesis We sought to identify factors related to short-term outcome of foot ulcers in patients with diabetes treated in a multidisciplinary
system until healing was achieved.
Methods Consecutively presenting patients with diabetes and worst foot ulcer (Wagner grade 1–5, below ankle) (n = 2,511) were prospectively followed and treated according to a standardised protocol until healing was achieved or until
death. The number of patients lost to dropout was 31. The characteristics of the remaining 2,480 patients were: 1,465 men,
age 68 ± 15 years (range 18–96), type 1 diabetes 18%, type 2 diabetes 82% and insulin-treated 62%.
Results The healing rate without major amputation in surviving patients was 90.6% (n = 1,867). Sixty-five per cent (n = 1,617) were healed primarily, 9% (n = 250) after minor amputation and 8% after major amputation; 17% (n = 420) died unhealed. Out of 2,060 surviving patients, 1,007 were neuroischaemic (48.8%). In a multiple regression analysis,
primary healing was related to co-morbidity, duration of diabetes, extent of peripheral vascular disease and type of ulcer.
In neuropathic ulcers, deep foot infection, site of ulcer and co-morbidity were related to amputation. Amputation in neuroischaemic
ulcers was related to co-morbidity, peripheral vascular disease and type of ulcer. Age, sex, duration of diabetes, neuropathy,
deformity and duration of ulcer or site of ulcer did not have an evident influence on probability of amputation.
Conclusions/interpretation Patients with diabetic foot ulcer suffer from multi-organ disease. Factors related to outcome are correspondingly complex. 相似文献

The risk of foot ulceration in diabetic patients with high foot pressure: a prospective study 总被引:12,自引:0,他引:12
Summary Foot ulceration results in substantial morbidity amongst diabetic patients. We have studied prospectively the relationship between high foot pressures and foot ulceration using an optical pedobarograph. A series of 86 diabetic patients, mean age 53.3 (range 17–77) years, mean duration of diabetes 17.1 (range 1–36) years, were followed-up for a mean period of 30 (range 15–34) months. Clinical neuropathy was present in 58 (67%) patients at baseline examination. Mean peak foot pressure was higher at the follow-up compared to baseline (13.5 kg·cm–2±7.1 SD vs 11.2±5.4, p<0.001) with abnormally high foot pressures (>12.3) being present in 55 patients at follow-up and 43 at the baseline visit (p=NS). Plantar foot ulcers developed in 21 feet of 15 patients (17%), all of whom had abnormally high pressures at baseline; neuropathy was present in 14 patients at baseline. Non-plantar ulcers occurred in 8 (9%) patients. Thus, plantar ulceration occurred in 35% of diabetic patients with high foot pressures but in none of those with normal pressures. We have shown for the first time in a prospective study that high plantar foot pressures in diabetic patients are strongly predictive of subsequent plantar ulceration, especially in the presence of neuropathy. 相似文献

Background and aimsTelemedicine had been proposed as a tool to manage diabetes, but its role in management of diabetic foot ulcer is still evolving. The COVID-19 pandemic and related social restrictions have necessitated the use of telemedicine in the management of diabetic foot disease (tele-podiatry), particularly of patients classified as low-risk.Materials and methodsWe present a report of three cases of varied diabetic foot problems assessed during the present pandemic using different forms of telemedicine for triaging, management of low-risk cases and for follow-up.ResultsTele-podiatry was effective in the management of low-risk subjects with diabetic foot ulcer, and also useful in referral of high-risk subjects for hospital/clinic visit, facilitating proper management. It also helped in the follow-up of the cases.ConclusionTelemedicine is a good screening tool for diagnosing and managing low-risk subjects with diabetic foot problems, and also enables a triaging system for deciding on hospital visits and hospitalization. Telemedicine offers several benefits in the management of diabetic foot disease, although it also has some limitations. Based on our experience during the pandemic, we recommend its judicious use in the triaging of patients of diabetic foot disease and management of low-risk cases. Future innovation in technology and artificial intelligence may help in better tele-podiatry care in the time to come. 相似文献

Background and aimsDiabetes mellitus (DM) is a chronic metabolic disease associated with long-term multisystem complications, among which nonhealing diabetic foot ulcers (DFUs) are recognized as major cause of morbidity and mortality. Treating DFUs with surgical procedures such as synthetic or biological skin grafts or skin substitutes has several limitations, where none of the currently available skin substitutes is ideal.MethodsOVID/Medline and PubMed databases were searched using the Medical Subject Heading (MeSH) or Title/Abstract words (“diabetic foot ulcers”, “skin substitutes”, and “nanofibers”), to identify published research studies on DFUs and nanofibers.ResultsElectrospinning nanotechnology is being used in the biomedical field to produce polymeric nanofibers impregnated with drugs for wound healing, burns and diabetic ulcers. Those nanofibers also enable seeding of cells into them and culturing them in vitro to synthesize tissue-like structures. Knowing the advantages of generating patient-specific induced pluripotent stem cells (iPSCs) and organoids in three-dimension (3D), including skin organoids, it is worth mingling these technologies to develop tissue-engineered biological skin substitutes.ConclusionNanofiber-skin substitutes hold promise for treatment of patients suffering from DFUs and inspire novel strategies that could be applied to other organ systems as well, introducing a new era of “regenerative and personalized medicine”. 相似文献

Objective
Functional polymorphisms within vascular endothelial growth factor (VEGF) gene have shown association with various conditions including diabetic neuropathy and retinopathy. In this study we have performed a candidate gene association study in order to examine VEGF gene polymorphism association with diabetic foot ulcer (DFU).Methods
The study group comprised of type 2 diabetes patients with (N = 247) and without (N = 241) DFU. Healthy control subjects (N = 98) were also recruited from the same area. The ARMS-PCR technique was applied for genotyping of VEGF gene SNPs at positions −7*C/T and −2578*C/A.Results
The frequency of genotype AA was significantly decreased in patients with DFU compared with diabetic subjects without DFU (AA vs CA + CC, p = 0.003, OR = 0.44, CI = 0.24-0.80). Also there was a significant decrease in frequency of A allele in patients with DFU compared to the controls (p = 0.02, OR = 0.68, CI = 0.48-0.96).Conclusion
It seems that lower frequency of A allele in patients with DFU is conferring a protective effect which might be as a result of increased angiogenesis in patients carrying this allele. 相似文献19.

During a 32-month period 94 foot ulcers in 54 diabetic patients aged 38-90 years (mean 64 years) were managed in a specialist foot clinic. Fifty-six percent were men, and they were significantly younger than women; 46% were taking insulin. Mean duration of diabetes was 13.4 years. Comparison with controls revealed a higher prevalence (p less than 0.01) of retinopathy (60% vs 23%), neuropathy (89% vs 31%), vasculopathy (71% vs 34%), arterial calcification (31% vs 20%) and previous lesions (54% vs 4%). There was no difference in quality of diabetic control, or smoking habit. A simple classification of lesions was used. All types yielded mixed cultures of microorganisms (average 2.1 per swab); the flora obtained was affected by systemic antibiotics. Abnormal pressure was judged to have contributed to all lesions occurring in areas of callus. In addition definable trauma precipitated the event in up to 60% of all other types. Lesions in areas of callus were more likely to have healed by the end of the study period, but average time to healing was significantly longer than other lesions. Despite intensive outpatient support, 33 patients spent a total of 1188 days in hospital during the 974 day period, an average of 36 days per patient and 1.2 beds per day. Further research is urgently required to define optimal methods of prevention and treatment of diabetic foot ulcers. 相似文献

Background & aimsDiabetic Foot Disease (DFD) management had to be redefined during COVID-19. We aim to evaluate the impact of this on diabetic foot care services and the strategies adopted to mitigate them.MethodsWe have performed a comprehensive review of the literature using suitable keywords on the Search engines of PubMed, SCOPUS, Google Scholar and Research Gate in the first two weeks of May 2020. We have reviewed how the diabetic foot service in the hospital and community setting has been affected by the current Coronavirus outbreak.ResultsWe found considerable disruption in diabetic foot service provisions both in the primary care and in the hospital settings. Social distancing and shielding public health guidelines have impacted the delivery of diabetic foot services.ConclusionAs the COVID-19 pandemic spreads worldwide, health care systems are facing the tough challenges in delivering diabetic foot service to patients. Public health guidelines and the risk of virus transmission have resulted in reconfiguration of methods to support and manage diabetic foot patients including remote consultations. 相似文献
