Abstract Background: A major complication of diabetes is diabetic foot ulcers. Millions of patients suffer from the physiological and psychosocial effects of diabetic foot ulcers. However, the current treatment is not effective, and the patients’ prognosis has not been significantly improved.Results: Traditional Chinese medicine-Zizhu ointment exhibited its own characteristics and advantages in treating diabetic foot ulcer by promoting wound healing. The mechanism of Zizhu ointment promoting diabetic foot ulcer wound healing was explored by detecting its miRNA expression profiling. Eighty-three differentially expressed miRNAs were identified, 30 of which were upregulated and 53 were downregulated in diabetic cutaneous wounds treated with Zizhu ointment. The Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis of the differentially expressed miRNAs showed that they were involved in several pathways that could regulate the proliferation, differentiation, apoptosis, migration, and secretion of tissue repair cells, and were linked to inflammatory cells, the extracellular matrix, growth factors, and other relevant factors related to wound healing. Furthermore, miRNA-Target regulatory network and protein-protein interaction network were constructed. Twenty hub genes of networks were obtained.Conclusions: Our preliminary study provides a new alternative drug treatment for diabetic foot ulcers by traditional Chinese medicine, and will assist in better understanding its therapeutic targets.

Abstract: A diabetic foot ulcer is a common and fearful chronic complication of diabetes mellitus often resulting in amputation, and even death. A diabetic foot ulcer can be prevented by early screening and education in high risk individuals, and the management of underlying conditions such as neuropathy, peripheral arterial disease, and deformity. The prevalence of diabetic foot ulcer patients is 4-10% of the general population, with a higher prevalence in elderly people. Around 14-24 % of diabetic foot ulcer patients need amputations with a recurrence rate of 50% after three years. The main pathogenesis of diabetic foot ulcer is neuropathy and peripheral arterial disease (PAD). PAD contributes to diabetic foot ulcers in 50% of cases; however, it rarely stands alone. Other factors such as smoking, hypertension, and hyperlipidemia may contribute, too. In addition, PAD reduces the access of oxygen and antibiotics to the ulcers. Management of diabetic foot ulcers includes treatment of ischemia by promoting tissue perfusion, debridement for removing necrotic tissues, wound treatment for creating moist wound healing, off-loading the affected foot, surgery intervention, management of the co-morbidities and infections, and prevention of wound recurrences. Other adjuvant modalities include hyperbaric oxygen treatment, GCSF, growth factors, and bioengineered tissues. Key words: diabetic ulcer, debridement, off loading.   Abstrak: Ulkus kaki diabetes (UKD) merupakan salah satu komplikasi kronik diabetes melitus yang sering dijumpai dan ditakuti oleh karena pengelolaannya sering mengecewakan dan berakhir dengan amputasi, bahkan kematian. UKD dapat dicegah dengan melakukan skrining dini serta edukasi pada kelompok berisiko tinggi, dan penanganan penyebab dasar seperti neuropati, penyakit artei perifer dan deformitas. Prevalensi pasien UKD berkisar 4-10% dari populasi umumnya, dengan prevalensi yang lebih tinggi pada manula. Sekitar 14-24% pasien UKD memerlukan amputasi dengan rekurensi 50 % setelah tiga tahun. Patogenesis utama UKD yaitu neuropati dan penyakit arteri perifer (PAP). PAP berkontribusi 50% pada pasien UKD, tetapi hal ini jarang dijumpai tunggal. Terdapat faktor-faktor lain yang turut berperan seperti merokok, hipertensi dan hiperlipidemia. Selain itu PAP menurunkan akses oksigen dan antibiotik ke dalam ulkus. Penatalaksanaan UKD meliputi penanganan iskemia dengan meningkatkan perfusi jaringan, debridemen untuk mengeluarkan jaringan nekrotik, perawatan luka untuk menghasilkan moist wound healing, off-loading kaki yang terkena, intervensi bedah, pananganan komorbiditas dan infeksi, serta pencegahan rekurensi luka. Terapi ajuvan meliputi terapi oksigen hiperbarik, pemberian granulocyte colony stimulating factors (GCSF), growth factors dan bioengineerd tissues. Kata kunci: ulkus diabetes, debridemen, off loading.

Aim. To describe differences in healing time of diabetic foot ulcers for patients treated at the Copenhagen Wound Healing Center, Bispebjerg Hospital, between the years 1999/2000 and 2011/2012. The Center is highly specialized and receives diabetes patients with hard-to-heal foot ulcers. A further aim is to attempt to find predictors of healing time of diabetic foot ulcers. Methods. A retrospective descriptive study of records from patients with diabetic foot ulcer treated at the Copenhagen Wound Healing Center in 1999, 2000, 2011, or 2012. Follow-up data was collected until the 3rd of August 2018. Results. Median time (range) to healing was 6 (61.3) months in 1999/2000 and 6.6 (67.8) in 2011/2012 (p=0.2). About 33% of ulcers were healed, 17% were minor or major amputated, and 1.5% were dead within one year in 1999/2000, whereas 30% of ulcers were healed (p=0.6), 14% were amputated (p=0.2), and 12.8% were dead within one year in 2011/2012 (p<0.001). The single factor found significantly associated with longer ulcer duration was infection. Related to shorter ulcer duration were toe localization of the ulcer and good glycemic control. Conclusion. The median time to healing of a diabetic foot ulcer was long, around 6 months and with a high recurrence rate in 1999/2000 as well as in 2011/2012. Some factors were found to be significantly related to healing time, and intervention addressing these may improve the time to heal, although such interpretations must be taken with precaution from the present study and should be proven in randomized prospective intervention trials.

Introduction: In 2012, the annual incidence rate of diabetic foot ulcers and gangrene are estimated to be around 2-5% of the general population. About 15% of patients with diabetic foot can have an amputation in the lower limb. Diabetic foot is a health problem that is very difficult to cure. This is further exacerbated by severe conditions of infection and disrupt the process of tissue regeneration, so amputation must be done to prevent the spread of infection. Infection that is not well controlled can inhibit all phases of wound healing. This study aimed to know the relationship between laboratory profile and wound healing in diabetic foot ulcer patients. Method: This was a cross-sectional study with research subjects who were diabetic foot ulcer patients who went to the emergency room and the Cipto Mangunkusumo National Hospital polyclinic during August-December 2019. Statistical analysis was performed to see the correlation between changes in infection marker values and changes in the wound area. Results: During the period August 2019 to December 2019, 30 subjects met the inclusion and exclusion criteria. There were 14 subjects (46.77%) male and 16 subjects (53.3%) female. From the diagnosis, there were 20 subjects (66.3%) with ulcer pedis and ten subjects (33.3%) gangrene pedis. From this study, the average and standard deviation of changes in ABI values were 0.9080 ± 0.100, changes in the number of leukocytes amounted to 4899.87 ± 4512.048, changes in ESR values was 1.8333 ± 1.147, changes in CRP values was 2.6500 ± 1.702, changes in wound area was 10.2727 ± 6.512, and albumin was 2.9487 ± 0.392. From the correlative analysis, it was found between changes in the number of leukocytes with changes in wound area (p=0.058, r=0.350), changes in ESR values with changes in wound area (p=0.034, r=0.388), and changes in CRP values with changes in wound area (p=0.008, r=0.477). Conclusion: There was a significant relationship between changes in ESR values and CRP values with moderate correlation strength changes in the wound area. There was no significant relationship between changes in the number of leukocytes with changes in the wound area. Keywords: wound area, leukocytes, CRP, ESR, diabetic foot ulcer, leukocytes.

One of the most prevalent complications of diabetes mellitus are diabetic foot ulcers (DFU). Diabetic foot ulcers represent a complex condition placing individuals at-risk for major lower extremity amputations and are an independent predictor of patient mortality. DFU heal poorly when standard of care therapy is applied. In fact, wound healing occurs only approximately 30% within 12 weeks and only 45% regardless of time when standard of care is utilized. Similarly, diabetic foot infections occur in half of all DFU and conventional microbiologic cultures can take several days to process before a result is known. DFU represent a significant challenge in this regard because DFU often demonstrate polymicrobial growth, become resistant to preferred antibiotic therapy, and do not inform providers about long-term prognosis. In addition, conventional culture yields may be affected by the timing of antibiotic administration and collection of tissue for analysis. This may lead to suboptimal antibiotic administration or debilitating amputations. The microbiome of DFU is a new frontier to better understand the interactions between host organisms and pathogenic ones. Newer molecular techniques are readily available to assist in analyzing the constituency of the microbiome of DFU. These emerging techniques have already been used to study the microbiome of DFU and have clinical implications that may alter standard of care practice in the near future. Here emerging molecular techniques that can provide clinicians with rapid DFU-related-information and help prognosticate outcomes in this vulnerable patient population are presented.

The aim of our study was to analyze the influence of radiographic arterial calcification (RAC) on clinical outcomes and wound healing in patients with diabetic foot ulcers complicated by osteomyelitis treated by surgery. We analyzed retrospectively the clinical records of 102 patients with diabetic foot osteomyelitis who underwent surgery at a specialized diabetic foot unit between January 2014 and December 2016. The clinical data of evolution until its complete epithelialization and a follow-up 1 year were reviewed, and after reviewing the radiological images, patients were classified into 2 groups: those with RAC and those without RAC. We analyzed several clinical features in both groups. The presence of RAC was associated with a greater time of healing (10.68 ± 7.24 vs 8.11 ± 4.50 weeks; P = .029) and shorter time to recurrence and reulceration (13.30 ± 9.25 vs 18.81 ± 11.63 weeks; P = .036). However, this association was not found for patients with mild and moderate peripheral artery disease (PAD), whose time of healing was 8.97 ± 4.51 weeks compared to 9.16 ± 6.39 weeks for patients without PAD; P = .864. The time of healing of diabetic foot ulcers complicated by osteomyelitis treated by surgery can be negatively affected by the presence of RAC even more than by the presence of mild and moderate ischemia. The presence of RAC may offer clinical guidance at the level of primary care though this would need thorough validation in future studies.

Diabetic Foot Ulcer (DFU) is one of the major complications of Diabetes. Patients with Diabetic Foot ulcers have a high susceptibility to microbial infections and are the leading cause of hospitalization and amputation of lower limbs. In the era of increased prevalence of bacterial resistance and outbreak of resistant infectious diseases, it is very essential to develop effective therapeutic strategies towards multi-drug resistant pathogens. The antimicrobial properties of silver nanoparticles have been well studied, therefore their use in biomedicine and pharmacology is a trend. Herein we present the use of Phyto-mediated synthesized AgNPs for the treatment of diabetic foot ulcers by topical administration. The nanoparticles were synthesized by reducing silver nitrate using Terminalia chebula fruit extract. The nanoparticles were analyzed and characterized using UV-Visible Spectrophotometer, FTIR, XRD, SEM with EDAX, TEM, and DLS. The synthesized silver nanoparticles were assayed for antimicrobial activity against five Diabetic Foot Ulcer bacterial isolates i.e. Escherichia coli, Klebsiella Pneumoniae, Pseudomonas aeruginosa, Streptococcus aureus, and Bacillus subtilis. The bactericidal property of synthesized nanoparticles was analyzed by the Agar well diffusion method, which revealed the remarkable antimicrobial effects against all the selective pathogenic bacterial isolates of Diabetic foot ulcers in the present study. These results constituted the basis for further studies on the use of plant-based silver nanoparticles for the treatment of Diabetic Foot ulcers from different origins

The rising prevalence of diabetes estimated at 3.6 million people in the UK represents a major public health and socioeconomic burden to our National Health Service. Diabetes and its associated complications are of a growing concern. Diabetes-related foot complications have been identified as the single most common cause of morbidity among diabetic patients. The complicating factor of underlying peripheral vascular disease renders the majority of diabetic foot ulcers asymptomatic until latter evidence of non-healing ulcers become evident. Therefore, preventative strategies including annual diabetic foot screening and diabetic foot care interventions facilitated through a multidisciplinary team have been implemented to enable early identification of diabetic patients at high risk of diabetic foot complications. The National Diabetes Foot Care Audit reported significant variability and deficiencies of care throughout England and Wales, with emphasis on change in the structure of healthcare provision and commissioning, improvement of patient education and availability of healthcare access, and emphasis on preventative strategies to reduce morbidities and mortality of this debilitating disease. This review article aims to summarise major risk factors contributing to the development of diabetic foot ulcers. It also considers the key evidence-based strategies towards preventing diabetic foot ulcer. We discuss tools used in risk stratification and classifications of foot ulcer.

AbstractDiabetes mellitus is a chronic metabolic disease associated with high cardiovascular risk. A vascular complication of diabetes is foot ulcers. Diabetic foot ulcers are prevalent and substantially reduce the quality of life of patients who have them. Currently, diabetic foot ulcer is a major problem for wound care specialists, and its treatment requires considerable health care resources. So far, various therapeutic modalities have been proposed to treat diabetic foot ulcers and one of them is stem cell-based therapy. Stem cell-based therapy has shown great promise for the treatment of diabetic foot ulcers. This strategy has been shown to be safe and effective in both preclinical and clinical trials. In this review, we provide an overview of the stem cell types and possible beneficial effects of stem cell transplantation therapy for diabetic foot ulcers, and an overview of the current status of stem cell research in both preclinical and clinical trial stages of treatment strategies for diabetic foot ulcers.
