Amputation in diabetic foot ulcer: A treatment dilemma

Diabetic foot is a clinical manifestation of diabetes with a wide range of symptoms, including ulceration, osteomyelitis, osteoarticular destruction, and gangrene, as a consequence of advanced disease. Some diabetic foot cases present general indications for amputation, including dead limb, threat to the patient’s life, pain, loss of function, or nuisance. Various tools have been introduced to help decision-making in amputation for diabetic foot. However, it remains a conundrum because diabetic foot involves multiple pathomechanisms and factors that hinder its outcomes. Sociocultural issues often impede treatment from the patient’s side. We reviewed different perspectives in diabetic foot management, particularly related to amputation. In addition to deciding whether to amputate, physicians should address amputation level, timing, and ways to avoid patient deconditioning. Surgeons should not be autocratic in these circumstances and should be aware of beneficence and maleficence when considering whether to amputate. The main goal should be improving the patients’ quality of life rather than preserving the limb as much as possible.

Risk factors for recurrence of diabetic foot ulcers: prospective follow‐up analysis in the Eurodiale subgroup

Few studies have examined factors associated with diabetic foot ulcer (DFU) recurrence. Using data from patients enrolled in the prospective Eurodiale DFU study, we investigated the frequency of and risk factors for DFU recurrence after healing during a 3‐year follow‐up period. At our site, 93 Eurodiale‐enrolled patients had a healed DFU. Among these, 14 were not alive; of the remaining 79 patients we enrolled 73 in this study. On entry to the Eurodiale study, we assessed demographic factors (age, sex and distance from hospital); diabetes‐related factors [duration, and glycated haemoglobin (HbA1c) levels]; comorbidities (obesity, renal failure, smoking and alcohol abuse) and DFU‐related factors [peripheral arterial disease, ulcer infection, C‐reactive protein (CRP) and; foot deformities]. During the 3‐year follow‐up period, a DFU had recurred in 42 patients (57·5%). By stepwise logistic regression of findings at initial DFU presentation, the significant independent predictors for recurrence were plantar ulcer location [odds ratio (OR) 8·62, 95% confidence interval (CI) 2·2–33·2]; presence of osteomyelitis (OR 5·17, 95% CI 1·4–18·7); HbA1c > 7·5% ([DCCT], OR 4·07, 95% CI 1·1–15·6) and CRP > 5 mg/l (OR 4·27, 95% CI 1·2–15·7). In these patients with a healed DFU, the majority had a recurrence of DFU during a 3‐year follow‐up period, despite intensive foot care. The findings at diagnosis of the initial DFU were independent risk factors associated with ulcer recurrence (plantar location, bone infection, poor diabetes control and elevated CRP) and define those at high risk for recurrence, but may be amenable to targeted interventions.

Risk factors for reamputation in patients with diabetic foot: A case-control study

BackgroundReamputation as a complication of diabetic foot ulcers presents a high economic burden and represents a therapeutic failure. It is paramount to identify as early as possible patients in whom a minor amputation may not be the best option. The purpose of this investigation was to do a case-controlled study to determine risk factors associated with re-amputation in patients with DFU (diabetic foot ulcers) at two University Hospitals.MethodsMulticentric, observational, retrospective, case-control study from clinical records of 2 university hospitals. Our study included 420 patients, with 171 cases (re-amputations), and 249 controls. We performed a multivariate logistic regression analysis and time-to-event survival analysis to identify re-amputation risk factors.ResultsStatistically significant risk factors were artery history of tobacco use (p = 0.001); male sex (p = 0.048); arterial occlusion in Doppler ultrasound (p = 0.001); percentage of stenosis in arterial ultrasound>50 % (p = 0.053); requirement of vascular intervention (p = 0.01); and microvascular involvement in photoplethysmography (p = 0.033). The most parsimonious regression model suggests that history of tobacco use, male sex, arterial occlusion in ultrasound, and percentage of stenosis in arterial ultrasound>50 % remained statistically significant. The survival analysis identified earlier amputations in patients with larger occlusion in arterial ultrasound, high leukocyte count, and elevated ESR.ConclusionDirect and surrogate outcomes in patients with diabetic foot ulcers identify vascular involvement as an important risk factor for reamputation.Level of evidenceIII     

Clinical outcomes of toe amputation in patients with type 2 diabetes in Tianjin,China

The aim of this study is to determine the predictors for reulceration, reamputation and mortality in patients with diabetes following toe amputation, and the impact of activities of daily living on clinical outcomes. This prospective cohort study included 245 patients who had undergone toe amputation (202 healing and 43 non‐healing) and was followed for a 5‐year period. Data regarding new foot ulceration, reamputation and mortality were recorded, and the patients' activities of daily living were evaluated. The rate of wound healing was 82·4%. The rate of follow‐up in the healed group was 91·6%. In years 1, 3 and 5, the cumulative incidence of patients who developed a new foot ulcer was 27·3%, 57·2% and 76·4%, respectively, leading to reamputation in 12·5%, 22·3% and 47·1%, respectively. The cumulative mortality was 5·8%, 15·1% and 32·7% at 1, 3 and 5 years, respectively. Multivariate analysis showed that GHbA1c > 9% (75 mmol/mol) was identified as an independent predictor of impaired wound healing, reulceration and reamputation. An age of >70 years was identified as an independent predictor of reamputation, mortality and impairment of activities of daily living. Despite a satisfactory initial healing rate after the first toe amputation, with the extension course after the toe amputation, the long‐term outcomes are not optimistic. In developing countries like China, taking measures to prevent reulceration and reamputation is very important for patients with diabetic foot minor amputations, especially following toe amputation.     

Single nucleotide variations in the development of diabetic foot ulcer: A narrative review

Diabetes mellitus has become a global health problem, and the number of patients with diabetic foot ulcers (DFU) is rapidly increasing. Currently, DFU still poses great challenges to physicians, as the treatment is complex, with high risks of infection, recurrence, limb amputation, and even death. Therefore, a comprehensive understanding of DFU pathogenesis is of great importance. In this review, we summarized recent findings regarding the DFU development from the perspective of single-nucleotide variations (SNVs). Studies have shown that SNVs located in the genes encoding C-reactive protein, interleukin-6, tumor necrosis factor-alpha, stromal cell-derived factor-1, vascular endothelial growth factor, nuclear factor erythroid-2-related factor 2, sirtuin 1, intercellular adhesion molecule 1, monocyte chemoattractant protein-1, endothelial nitric oxide synthase, heat shock protein 70, hypoxia inducible factor 1 alpha, lysyl oxidase, intelectin 1, mitogen-activated protein kinase 14, toll-like receptors, osteoprotegerin, vitamin D receptor, and fibrinogen may be associated with the development of DFU. However, considering the limitations of the present investigations, future multi-center studies with larger sample sizes, as well as in-depth mechanistic research are warranted.     

A retrospective study of diabetic foot ulcers treated with hyperbaric oxygen therapy

A retrospective review of patient medical records was conducted to assess what factors influence the outcomes of diabetic foot ulcers treated with hyperbaric oxygen (HBO) therapy. Patients referred to the Diving Diseases Research Centre for HBO therapy for the treatment of diabetic foot ulcers during a 2‐year period were included in this study. Data collected from 30 sets of patient records were entered into SPSS and statistical analysis was undertaken to investigate whether any underlying pathologies or confounding factors appeared to influence patient outcome. A 73·3% of patients achieved a successful outcome of partial healing, major amputation no longer required, amputation level lower than anticipated prior to HBO or healing at the end of HBO therapy and 70% remained successful 3 months later. A 13·3% of patients were lost to follow‐up at 3 months and one patient (3·3%) had a major amputation. Steroid therapy, peripheral vascular disease, previous minor amputation, type of diabetes, previous HBO therapy, larvae therapy, the use of interactive dressings and haemoglobin A1c levels were all observed to have had a significant relationship with patient outcome (P < 0·05). These results were compared with data from other published research conducted in this area on similar patient groups. A larger scale study focussing on the factors found to be significant in this study is recommended. An improvement of patient documentation would allow patient outcomes to be more consistently monitored in the future.     

An assessment of peripheral vascular disease in patients with diabetic foot ulcer

BackgroundPeripheral vascular disease (PVD) is a chronic limb ischaemia caused by atherosclerosis of the peripheral arteries. Diabetes mellitus is a risk factor for this disease. The most common symptom of PVD is muscle pain in the lower limbs on exercise. In diabetes, pain perception may be blunted by the presence of peripheral neuropathy. Therefore, a patient with diabetes and PVD is more likely to present with an ischaemic ulcer or gangrene than a patient without diabetes. The use of ankle-brachial-pressure index (ABI) in the clinic and bedside provide a measure of blood flow to the ankle. This could help early detection, initiate early therapy and may thus reduce the risk of critical limb ischaemia and limb loss.ObjectiveThe purpose of this study is to evaluate the occurrence of peripheral vascular disease using ankle-brachial index in diabetic patients with and without foot ulcers and the risk factors associated with diabetic foot ulcer (DFU).MethodThis prospective study involved all type 2 DM patients with foot ulcer (DFU population) and those without foot ulcers (non-DFU population) seen in our hospital. Their demographic, clinical and laboratory parameters were noted and documented. Measurement of ABI was done using a portable hand held Doppler and ankle pressures < 0.9 is suggestive of PVD.ResultsA total of 74 patients were recruited. Males were 42 (56.8%) and females were 32 (43.2%). The mean age of the patients was 62.89 ± 10.66 years and the duration of diabetes was 7.61 ± 7.57 years. Forty-six (62.2%) presented with foot ulcer while 28 (37.8%) were without foot ulcer. Patients with PVD represented by ABI < 0.9 was DFU 31(76.4%) while in non-DFU it was 10 (13.4%). Multivariant analysis of variables associated with DFU in those with ABI < 0.9 showed correlation with tobacco use r = .235, p = 0.044; duration of diabetes r = ?.427; p = 0.001; and systolic blood pressure r = ?.301; p = 0.009.DiscussionThe occurrence of PVD determined by the absence of >2 pulses by palpation alone and using ABI was 25.7% and 55.4% respectively. This suggests that assessment by palpation is subjective while the use of Doppler is quantitative and more reliable. DFU patients with PVD showed a significant correlation with tobacco use, duration of diabetes and systolic blood pressure but not with dyslipidaemia.ConclusionThis study shows that these patients had risk factors for PVD. The use of hand held Doppler will aid early diagnosis of critical limb at risk of loss and help to prevent and reduce the high rate of limb loss in our patients.

Relationship between maceration and wound healing on diabetic foot ulcers in Indonesia: a prospective study

The aim of this study was to clarify the relationship between maceration and wound healing. A prospective longitudinal design was used in this study. The wound condition determined the type of dressings used and the dressing change frequency. A total of 62 participants with diabetic foot ulcers (70 wounds) were divided into two groups: non‐macerated (n = 52) and macerated wounds (n = 18). Each group was evaluated weekly using the Bates–Jensen Wound Assessment Tool, with follow‐ups until week 4. The Mann–Whitney U test showed that the changes in the wound area in week 1 were faster in the non‐macerated group than the macerated group (P = 0·02). The Pearson correlation analysis showed a moderate correlation between maceration and wound healing from enrolment until week 4 (P = 0·002). After week 4, the Kaplan–Meier analysis showed that the non‐macerated wounds healed significantly faster than the macerated wounds (log‐rank test = 19·378, P = 0·000). The Cox regression analysis confirmed that maceration was a significant and independent predictor of wound healing in this study (adjusted hazard ratio, 0·324; 95% CI, 0·131–0·799; P = 0·014). The results of this study demonstrated that there is a relationship between maceration and wound healing. Changes in the wound area can help predict the healing of wounds with maceration in clinical settings.     

Risks to feet in the top end: outcomes of diabetic foot complications

Background : The foot complications of diabetes are severe, disabling, costly and common in the Northern Territory. An understanding of the pathogenesis, the disease spectrum and treatment efficacy, however, is poor. The patterns of disease are documented in the present study; factors associated with good and poor outcomes are identified; and improved management strategies are proposed. Methods : All patients presenting to the High Risk Foot Service at Royal Darwin Hospital between March 1997 and March 2000 were included in the present study, and details regarding the status of their feet, their demographics, their treatment and their outcomes were recorded prospectively. Logistic regression analysis was undertaken to determine associations between factors of interest and outcomes of healing and amputation. Results : One hundred and twenty‐six patients were recorded, 41% of whom had neuropathic ulcers and 63% of whom had severe disease at presentation. Two types of diabetic foot pathology were recognized that are not usually classified: acute injury without neuropathy (10%) and deep soft tissue infection alone (9%).Thirty‐seven percent and 23% of patients required minor and major amputations, respectively. The total number of hospital bed‐days was 5813. Total contact casting was associated with good healing rates in 16 patients. Major amputation was associated with ischaemia, severe disease at presentation and increasing age. Conclusions : Patterns of diabetic foot disease which are not commonly recognized are described in the present study; the severity and cost of the problem are documented; and some factors which lead to poor outcome, such as late presentation, are identified. Attention should be paid, through a multidisciplinary team, to timely referral from primary care, patient education, total contact casts and appropriate revascularization.
