Early diagnosis and a multidisciplinary team approach to manage comorbidities is essential in treating Diabetic Foot Ulcerations (DFUs). The lifetime risk of a foot ulcer in patients with diabetes mellitus (DM) is high. DFUs are a major cause of morbidity in these patients. Infected or ischemic DFUs account for approximately 25% of all hospital stays for patients with DM. Based on data from the World Health Organization, lower extremity complications of DM are among the top ten conditions in terms of years lived with disability. Moreover, patients with DM with or without a foot ulcer have increased rates of depression. These observations illustrate the importance of prompt and appropriate treatment of DFU. The information in this review of guidelines is aimed to guide the healthcare professionals involved in the care of persons with DM and DFUs. [ABSTRACT FROM AUTHOR]

Diabetic foot ulcer (DFU), if untreated, accounts for lower-limb amputations affecting patients' quality-of-life. Diperoxochloric acid (DPOCL) is known to heal DFU by its antibacterial and fibroblast stimulating activity. This was a phase 3, multicentre, randomized, double-blind, active-controlled, parallel-group study conducted to evaluate the efficacy and safety of topic solution of DPOCL compared with isotonic sodium chloride solution (ISCL). Adult patients with type 1 or 2 diabetes with random blood glucose levels of <250 mg/dL, with ≤ than three full-thickness foot ulcers were enrolled. Primary efficacy endpoint was complete wound closure and secondary was wound surface area. Adverse events were analyzed as safety endpoint. Of 311 enrolled patients, 289 were randomized 1:1 to DPOCL (139) and ISCL (150) treatment (10-weeks [8-Visits]). Percentage of patients with complete wound closure at visit-8, were significantly higher (P =.0156) in DPOCL arm (76% [105/139]) compared to ISCL (62% [93/150]) arm. At end-of-study, mean wound surface area in DPOCL arm (0.639 cm2) was significantly lower (P =.0209) compared to ISCL (0.818 cm2) arm. One death was reported in control arm which was not considered as treatment-related. No important safety finding were observed. Results indicate that, DPOCL can be considered as effective and safe treatment option for DFU compared to ISCL, although future confirmatory studies are warranted. [ABSTRACT FROM AUTHOR]

Background: There are uncertainties regarding the diagnostic criteria, optimal treatment methods, interventions, monitoring and determination of remission of Charcot neuro‐osteoarthropathy (CNO) of the foot and ankle in people with diabetes mellitus (DM). The aims of this systematic review are to investigate the evidence for the diagnosis and subsequent treatment, to clarify the objective methods for determining remission and to evaluate the evidence for the prevention of re‐activation in people with CNO, DM and intact skin. Methods: We performed a systematic review based on clinical questions in the following categories: Diagnosis, Treatment, Identification of Remission and Prevention of Re‐Activation in people with CNO, DM and intact skin. Included controlled studies were assessed for methodological quality and key data from all studies were extracted. Results: We identified 37 studies for inclusion in this systematic review. Fourteen retrospective and observational studies relevant to the diagnosis of active CNO with respect to clinical examination, imaging and blood laboratory tests in patients with DM and intact skin were included. We identified 18 studies relevant to the treatment of active CNO. These studies included those focused on offloading (total contact cast, removable/non‐removable knee high devices), medical treatment and surgical treatment in the setting of active CNO. Five observational studies were identified regarding the identification of remission in patients who had been treated for active CNO. We did not identify any studies that met our inclusion criteria for the prevention of re‐activation in patients with DM and intact skin who had been previously treated for active CNO and were in remission. Conclusions: There is a paucity of high‐quality data on the diagnosis, treatment, and prognosis of active CNO in people with DM and intact skin. Further research is warranted to address the issues surrounding this complex disease. [ABSTRACT FROM AUTHOR]

The International Working Group on the Diabetic Foot (IWGDF) has published evidence‐based guidelines on the prevention and management of diabetic foot disease since 1999. This is the first guideline on the diagnosis and treatment of active Charcot neuro‐osteoarthropathy in persons with diabetes published by the IWGDF. We followed the GRADE Methodology to devise clinical questions in the PACO (Population, Assessment, Comparison, Outcome) and PICO (Population, Intervention, Comparison, Outcome) format, conducted a systematic review of the medical literature, and developed recommendations with the rationale. The recommendations are based on the evidence from our systematic review, expert opinion when evidence was not available, and also taking into account weighing of the benefits and harms, patient preferences, feasibility and applicability, and costs related to an intervention. We here present the 2023 Guidelines on the diagnosis and treatment of active Charcot neuro‐osteoarthropathy in persons with diabetes mellitus and also suggest key future topics of research.

Aims: Available literature on the prevalence of Charcot arthropathy (CA) represents mainly Western population. No study has been reported from India so far. Hence we attempted to study the prevalence of CA in patients with type 2 diabetes mellitus and severe peripheral neuropathy (T2DMPN), belonging to Indian population amongst whom type 2 diabetes is on the rise in alarming proportions. Materials and Methods: Medical records of 3387 patients who performed an objective vibration perception threshold test during the year 2015 were screened for T2DMPN. Out of these, 1475 T2DMPN patients above 50 years were selected and analyzed in detail for CA. CA was diagnosed based on clinical features and/or radiological investigations. The anatomical localization of the disease distribution of the affected foot was done according to Brodsky's classification. Results: The prevalence of CA in T2DMPN patients was found to be 9.8%. The mean age of patients diagnosed with CA was 63 ± 8.36 years, and mean duration of DM for CA to develop was 18.01 ± 8.23 years. About 62.5% of the patients were male and 37.5% female. Bilateral presentation of CA was observed in 20.8% of patients. Multiple sites of the foot were affected in 48.6% of patients and belonged to type 4 classification of Brodsky. Conclusions: A high prevalence of CA (9.8%) was observed in the present study conducted on T2DMPN patients who presented to the endocrinology department of a tertiary care South Indian hospital. In the majority of patients, the area of foot affected belonged to type 4 classification of Brodsky.

Background: Charcot arthropathy (CA) is a progressive noninfectious inflammatory disease that causes irreversible destruction to pedal architecture in diabetic neuropathy (DN) patients. The debilitating prognosis demands early detection to prevent the development and progression of this disorder. Dysregulated and persistent production of inflammatory cytokines is reported as the key element in initiating osteoclastogenesis in CA. The study analyzed the potential association of markers of inflammation and bone turnover of prediagnostic serum samples on CA. Methods: Seventy-one type 2 severe DN patients were selected based on inclusion-exclusion criteria. Serum samples of interleukin 6 (IL-6), osteoprotegerin (OPG), bone alkaline phosphatase (BALP), and C-reactive protein (CRP) were analyzed. These patients were followed for the development of symptoms of CA for 12 months. In the year of monitoring, 7 patients developed CA (group 1), whereas the remaining 64 patients did not develop CA (group 2). Results: The rate of development of CA in patients with severe DN was 9.8%. In this group, significantly increased median values of HbA1c (group 2: 8.00 [7.00-9.00], group 1: 10.00 [9.25-11.50], P =.013); IL-6 (group 2: 1.21 [0.72-2.16], group 1: 11.08 [6.65-63.64], P =.008); and CRP (group 2: 1.25 [0.78-3.20], group 1: 3.31 [1.18-41.33], P =.041) were found. The receiver operating characteristic analysis showed that IL-6 was more strongly associated with the onset of CA (IL-6: area under the curve = 0.808; P =.008) than CRP. Cut-off values of ≥6.6 for IL-6 show potential to rule out CA in high-risk patients, with a positive predictive value of 26.1%, a negative predictive value of 97.9%, a sensitivity of 85.7%, and a specificity of 73.4%. Conclusion: In our study population, we found that an exacerbated inflammatory state, reflected by IL-6 values, generally occurred in DN patients before the clinical detection of CA. Level of Evidence: Level II, prospective comparative study. [ABSTRACT FROM AUTHOR]

Hyperglycemia impairs healing of diabetic foot ulcer (DFU). But there is no evidence regarding benefit of intensive glucose control for healing of DFU. We plan to conduct a randomized, parallel arm, controlled study to assess the role of intensive glycemic management in comparison to conventional glucose control for healing of DFU. Participants with neuropathic DFU (infected or uninfected) having hemoglobin A1c (HbA1c) >8% and without evidence of osteomyelitis from 7 tertiary care hospitals will be enrolled. They will undergo a 2-week run-in phase for optimization of comorbidities, ulcer debridement, and counseling regarding self-monitoring of blood glucose (SMBG). Subsequently, they will be randomized to "intensive glycemic control" arm defined by glycemic targets of fasting blood glucose (FBG) <130 mg/dL, postprandial BG <180 mg/dL, and HbA1c <8%, with basal-bolus insulin regimen and frequent titration of insulin to achieve glycemic targets. The "conventional" arm will continue on prior treatment (oral antidiabetic drugs) with no titration unless meeting rescue criteria. Ulcer area will be calculated by automated wound assessment device (WoundlyClinial app) weekly for first 4 weeks, and less frequently until the 24th week. Standard treatment for DFU, off-loading, and counseling for foot care will be provided in both arms. The primary outcome measure will be number of wounds closed at 12th and 24th weeks. A multivariate regression analysis will be performed to identify the predictors of wound healing with baseline HbA1c, diabetes duration, wound size, wound duration, and background therapies as independent variable. This study will provide the much needed guidance to set optimum glucose targets in people with DFU. [ABSTRACT FROM AUTHOR]

Introduction: Charcot arthropathy (CA) is non-infective, chronic destructive condition affecting the pes architecture of long standing diabetic patients with neuropathy. Even though several theories have emerged to disclose its pathogenesis, inflammatory cytokine induced osteoclastogenesis stands as the chief culprit. Studies on micro-architecture of foot bones of acute stage CA patients, describes mainly destructive phase of bone remodelling. Increased osteoclast cell activity is reported in all studies communicated. No study has to the best of our knowledge detailed the microscopic structure of chronic stage CA foot bones., Aim: To study the microscopic structure of foot bones in patients with chronic CA., Materials and Methods: Foot bones were collected from the feet of chronic CA patients (six in number) who underwent corrective foot surgery in the Department of Podiatric Surgery of a tertiary care hospital. Control samples were collected from the feet of age matched non-diabetic controls (2 in number). The samples were fixed in formalin, decalcified in 10% nitric acid, processed, sectioned and stained with haematoxylin and eosin. Histopathology and histomorphometry analysis were performed by two different pathologists., Results: Trabeculae of chronic CA foot bones exhibited mainly a lamellar architecture, with reduced number of osteocytes and plenty of empty lacunae. Trabecular connectivity was lost and trabeculae showed considerable thinning. Trabecular osteoids lined by active osteoblast cells was a remarkable observation. Bone area was also considerably reduced in chronic CA foot bones., Conclusion: Chronic stage CA foot bones presented features of both healing and fragile bone. The compromised bone quality may be due to thin and fragmented trabecular structure and reduced cellularity.

Of total diabetic population, 15-20% have foot problems and 30% have peripheral vascular disease. The fundamental strategy for foot salvaging is 'early conservative amputation and radical debridement' of diabetic foot infection. For this strategy, concept of foot spaces is to be well understood. Guidelines for 'early conservative amputation and radical debridment' are discussed in this article. As regarding diabetic foot care ten valuable points are to be remembered which are also discussed.
