- Abstract
Objectives: The objective of this paper was to assess hospitalizations and health resource utilization associated with diabetic foot infection (DFI)-related visits within emergency departments (EDs) in the U.S. Methods: This nationally representative, cross-sectional historical cohort utilized the Centers for Disease Control and Prevention's (CDC's) National Hospital Ambulatory Medical Care Survey across a ten-year period from 2012 to 2021. Inclusion criteria were as follows: adults ≥18 years of age; a diagnosis of Type 1 or Type 2 diabetes mellitus; presence of a DFI. Comparisons were drawn relative to a cohort of patients with diabetes without foot complications. Study outcomes included 72-hour (72 h) ED revisit, hospitalization, and length of stay (LOS). Top diagnoses and medications were also reported. Multivariable, generalized, linear regression analyses were employed, controlling for key demographics, health system factors, clinical characteristics, and year. Results: An estimated 150.6 million ED visits included a diabetes diagnosis, with 2.4 million involving a DFI (1.6%). Approximately half of DFI cases were hospitalized (43.7%). Anti-infective medications were prescribed in 83.1% of DFI cases, including vancomycin in 28.1%. Multivariable analyses observed that DFIs were associated with a 3.002 times higher odds of hospital admissions (CI: 2.145–4.203, p < 0.001) and a 55.0% longer LOS (IR = 1.550, CI: 1.241–1.936, p < 0.001). DFIs were not significantly associated with a 72 h ED revisit. Conclusions: This nationally representative study of 2.4 million DFI-related ED visits in the U.S. observed higher odds of hospital admissions and a longer LOS for DFIs versus diabetes without foot complications. Continued research should seek to assess prevention and coordinated treatment interventions prior to the emergence of DFIs requiring ED care. [ABSTRACT FROM AUTHOR]

Background: Diabetes‐related foot infections are common and represent a significant clinical challenge. There are scant data about outcomes from large cohorts. The purpose of this study was to report clinical outcomes from a large cohort of people with diabetes‐related foot infections. Methods: A tertiary referral hospital limb preservation service database was established in 2018, and all new episodes of foot infections were captured prospectively using an electronic database (REDCap). People with foot infections between January 2018 and May 2023, for whom complete data were available on infection episodes, were included. Infection outcomes were compared between skin and soft tissue infections (SST‐DFI) and osteomyelitis (OM) using chi‐square tests. Results: Data extraction identified 647 complete DFI episodes in 397 patients. The data set was divided into two cohorts identifying each infection episode and its severity as either SST‐DFI (N = 326, 50%) or OM (N = 321, 50%). Most infection presentations were classified as being moderate (PEDIS 3 = 327, 51%), with 36% mild (PEDIS 2 = 239) and 13% severe (PEDIS 4 = 81). Infection resolution occurred in 69% (n = 449) of episodes with failure in 31% (n = 198). Infection failures were more common with OM than SST‐DFI (OM = 140, 71% vs. SST‐DFI = 58, 29%, p < 0.00001). In patients with SST‐DFI a greater number of infection failures were observed in the presence of peripheral arterial disease (PAD) compared to the patients without PAD (failure occurred in 30% (31/103) of episodes with PAD and 12% (27/223) of episodes without PAD; p < 0.001). In contrast, the number of observed infection failures in OM episodes were similar in patients with and without PAD (failure occurred in 45% (57/128) of episodes with PAD and 55% (83/193) of episodes without PAD; p = 0.78). Conclusions: This study provides important epidemiological data on the risk of poor outcomes for DFI and factors associated with poor outcomes in an Australian setting. It highlights the association of PAD and treatment failure, reinforcing the need for early intervention to improve PAD in patients with DFI. Future randomised trials should assess the benefits of revascularisation and surgery in people with DFI and particularly those with OM where outcomes are worse. [ABSTRACT FROM AUTHOR]

Diabetic foot infection imposes a significant burden and is the major cause of nontraumatic limb amputation. Adequate patient management with effective antibiotic therapy is crucial. This retrospective cohort study aimed to characterize the microbiology and resistance patterns of moderate to severe neuropathic diabetic foot infection in patients hospitalized at a tertiary referral hospital between January 2020 and June 2023. Deep tissue specimens from ulcers were collected for culture. Sixty inpatients were included (62% male, mean age 59.1 ± 11.5 years). Osteomyelitis was present in 90% of the patients. Among 102 microorganisms (average of 1.91 ± 1.25 pathogens per patient), 60.8% were gram-positive bacteria, 31.4% were gram-negative, 3.92% were anaerobic bacteria, and 3.92% were fungi. Staphylococcus aureus (19%) and Enterococcus faecium (17%) were the most common. Pseudomonas aeruginosa (8%) and bacteria of the Enterobacterales family (24%) accounted for all the isolated gram-negative bacteria. Sixteen percent of Staphylococcus aureus and 67% of coagulase-negative Staphylococci were resistant to methicillin. Resistance to ampicillin was found in 11% of Enterococci. All Pseudomonas aeruginosa isolates were sensitive to piperacillin-tazobactam, ceftazidime, or cefepime. Among the Enterobacterales, resistance rates were 35% for piperacillin-tazobactam, 38% for ceftazidime, 21% for cefepime, and 13% for carbapenems. Although the prevalence of methicillin-resistant staphylococci was lower than that in other studies, carbapenem resistance among gram-negative bacteria warrants attention. This study highlights the importance of understanding local epidemiology for effective diabetic foot infection management and resistance mitigation. [ABSTRACT FROM AUTHOR]

Diabetes Mellitus (DM) is a significant global concern. Many diabetic patients will experience complications due to angiopathy, neuropathy, and immune dysfunction, namely diabetic foot ulcers (DFU) and diabetic foot infections (DFI), which can result in lower limb amputation and potentially death. The prevalence of common superficial fungal infections, such as tinea pedis and onychomycosis, can directly increase a diabetic patient's risk of developing both DFU and DFI. In this review article, we discuss the etiology of diabetic foot complications as well as considerations for both screening and management. We also discuss the role of the dermatologist within a multidisciplinary care team in prescribing and managing treatments for tinea pedis and onychomycosis infections within this patient population. We believe that reducing the burden of these fungal infections in the context of the diabetic foot will help reduce DFU and DFI complications and their associated morbidity and mortality.

Background: Foot infections, a frequent complication of diabetes mellitus, are associated with heavy resource utilization, including antibiotic therapy and surgeries. However, the most common type of isolated pathogen in diabetic foot infections remains unknown. We aimed to identify the most common types of isolated pathogens in diabetic foot infections. Methods: This retrospective cohort study was conducted in a specialized medical center in Jeddah, Saudi Arabia. A total of 96 patients diagnosed with diabetes and presented with a foot ulcer showing clinical signs of infection were included. Results: The mean age was 63.03 ± 10.88 years, and 67.7% were males. The mean duration of diabetes diagnosis was 21.86 ± 9.66 years, and the majority had foot ulcers for over six weeks. Bacteria were present in 65 patients (67.7%), Gram-negative organisms were observed in 37 patients (38.5%), and Gram-positive organisms were present in 28 patients (29.2%). In the 65 patients with bacterial culture, Staphylococcus aureus was the most common isolated organism and was observed in 18 patients (27.7%), followed by Escherichia coli in 11 (16.9%) and Pseudomonas aeruginosa in 10 (15.4%). Binary regression analyses found that Gram-negative organisms were significantly more multidrug-resistant than Gram-positive organisms (P = 0.012, OR = 7.172, 95% CI = 1.542–33.352). Patient outcomes included healed ulcers (n = 10, 10.4%), minor amputation (n = 16, 16.7%), major amputation (n = 1, 1%), and debridement (n = 48, 50%). Conclusion: Gram-negative organisms were predominant in patients with diabetes and foot ulcers having clinical signs of infection. Treatment with an individualized antibiotic regimen is vital in ensuring optimal outcomes and preventing major amputations.

Abstract Negative pressure wound therapy with instillation and dwell time (NPWTi-d) is increasingly used for a diverse range of wounds. Meanwhile, the topical wound irrigation solution consisting of polyhexamethylene biguanide and betaine (PHMB-B) has shown efficacy in managing wound infections. However, the effectiveness of this solution as a topical instillation solution for NPWTi-d in patients with diabetic foot infections (DFIs) has not been thoroughly studied. The objective of this retrospective study was to evaluate the impact of using PHMB-B as the instillation solution during NPWTi-d on reducing bioburden and improving clinical outcomes in patients with DFIs. Between January 2017 and December 2022, a series of patients with DFIs received treatment with NPWTi-d, using either PHMB-B or normal saline as the instillation solution. Data collected retrospectively included demographic information, baseline wound characteristics, and treatment outcomes. The study included 61 patients in the PHMB-B group and 73 patients in the normal saline group, all diagnosed with DFIs. In comparison to patients treated with normal saline, patients with PHMB-B exhibited no significant differences in terms of wound bed preparation time (P = 0.5034), length of hospital stay (P = 0.6783), NPWTi-d application times (P = 0.1458), duration of systematic antimicrobial administration (P = 0.3567), or overall cost of hospitalization (P = 0.6713). The findings of the study suggest that the use of either PHMB-B or normal saline as an instillation solution in NPWTi-d for DFIs shows promise and effectiveness, yet no clinical distinction was observed between the two solutions.

Background When treating diabetic foot osteomyelitis (DFO), it remains difficult to determine the presence of residual infection and the optimal treatment after bone resection. In this study, we aimed to investigate the clinical characteristics of and prognostic factors in patients with DFO undergoing amputation. Methods This retrospective study involved 101 patients with DFO who underwent amputation. Data on their demographics, clinical characteristics, tissue culture, and surgery type were collected. Patients were grouped according to primary closure status and clinical outcome postamputation. A good outcome was defined as a successful complete remission, characterized by the maintenance of complete wound healing with no sign of infection at 6 months postamputation. Multivariate logistic regression analysis was performed. Outcomes according to surgery type were also analyzed. Results Staphylococcus aureus (17%) and Pseudomonas species (14%) were the most prevalent pathogens. Gram-negative bacteria were isolated from 62% of patients. In patients with primary closure, hemodialysis and ankle brachial index (ABI) <0.6 were associated with poor outcomes. In patients with DFO, ABI <0.6 was the only prognostic factor associated with treatment failure. Antimicrobial stewardship allows patients who underwent major amputation to reduce the duration of antibiotic therapy compared to those after minor amputation, although it did not contribute to reducing mortality. Conclusions Peripheral artery disease and hemodialysis were associated with poor outcomes despite radical resection of the infected bone. Vigilant monitoring after amputation and antimicrobial stewardship implemented based on microbiological epidemiology, prognostic factors, and the type of surgery are important. A multidisciplinary team could assist in these activities to ensure treatment success. [ABSTRACT FROM AUTHOR]

The aim of this study was to evaluate the diagnostic characteristics of biomarker for diabetic foot osteomyelitis (DFO). We searched PubMed, Scopus, Embase and Medline for studies who report serological markers and DFO before December 2022. Studies must include at least one of the following diagnostic parameters for biomarkers: area under the curve, sensitivities, specificities, positive predictive value, negative predictive value. Two authors evaluated quality using the Quality Assessment of Diagnostic Accuracy Studies tool. We included 19 papers. In this systematic review, there were 2854 subjects with 2134 (74.8%) of those patients being included in the meta‐analysis. The most common biomarkers were erythrocyte sedimentation rate (ESR), C‐reactive protein (CRP) and procalcitonin (PCT). A meta‐analysis was then performed where data were evaluated with Forrest plots and receiver operating characteristic curves. The pooled sensitivity and specificity were 0.72 and 0.75 for PCT, 0.72 and 0.76 for CRP and 0.70 and 0.77 for ESR. Pooled area under the curves for ESR, CRP and PCT were 0.83, 0.77 and 0.71, respectfully. Average diagnostic odds ratios were 16.1 (range 3.6–55.4), 14.3 (range 2.7–48.7) and 6.7 (range 3.6–10.4) for ESR, CRP and PCT, respectfully. None of the biomarkers we evaluated could be rated as 'outstanding' to diagnose osteomyelitis. Based on the areas under the curve, ESR is an 'excellent' biomarker to detect osteomyelitis, and CRP and PCT are 'acceptable' biomarkers to diagnose osteomyelitis. Diagnostic odds ratios indicate that ESR, CRP and PCT are 'good' or 'very good' tools to identify osteomyelitis. [ABSTRACT FROM AUTHOR]

Diabetic Foot Ulcers (DFUs) are open ulcers or sores on the foot with a bony prominence. They are a frequent manifestation of uncontrolled diabetes mellitus and often increase the risk of infection. DFUs typically take longer to heal, sometimes resulting in severe complications such as amputation. Our study aimed to develop a drug delivery system that could help to manage DFUs. We developed polymer-based fibers that were loaded with ciprofloxacin HCl via centrifugal spinning setup. The optimized polymeric fiber batch demonstrated over 90% drug entrapment, controlled drug release for 72 h, an average fiber diameter of 4.88 pm and porosity above 70%. The drug-loaded fibers showed antibacterial action against gram-negative (E. coli) and gram-positive (S. aureus) pathogens that are often prevalent in DFUs. Additionally, the fibers showed excellent hemocompatibility. Our study's findings show great potential in managing DFUs, and future studies will explore the potential application of this drug delivery system in treating and managing diabetic foot ulcers.

Osteomyelitis (OM) in diabetic foot infection could have many presentations such as an infected ulcer spreading to the bone or superimposed to Charcot neuroarthropathy. However, the sausage toe as a diabetic OM presentation was very rarely investigated; therefore, this study aims to assess the prevalence and signs of this presentation along with treatment modalities and outcomes. This is a retrospective series of patients presenting a sausage toe on admission. Several methods were conducted to diagnose OM, and three treatment modalities were applied. Two groups were compared: acute and chronic sausage toes. Outcomes were defined as sausage toe prevalence, ulcer location, OM prevalence, and comparative treatment results. Out of 82 diabetic toe infection cases, 24 (30%) presented as 'sausage toe'. The side of the proximal interphalangeal joint of the lateral toes was the most frequent ulcer location (50%), mostly on the dorsal aspect followed by the side aspect. There were 15 (62.5%) acute cases and 9 (37.5%) chronic cases. MRI showed signs of OM in 21 (87.5%) cases and signs of septic arthritis in 3 (12.5%) cases. At the final follow‐up, a successful treatment was recorded in five (20%) cases with antibiotics alone. Out of the 19 (42%) procedures, conservative surgery was performed successfully in 8 (58%) cases while amputation was needed in 11 (45.8%) cases. There was no significant difference in amputation frequency between acute and chronic groups. This is the first study documenting the sausage toe as a prevalent presentation of diabetic toe infection. The deformity is conclusive of deep infection with a very high osteomyelitis frequency. Surgery is often required for infection control and healing, mainly for chronic cases, and treatment outcomes did not differ between acute and chronic sausage toe groups. It could be beneficial to include this entity in the diabetic wound classification systems. [ABSTRACT FROM AUTHOR]

Background/Aim: Diabetic foot infection (DFI) occurs frequently in patients, followed up with diabetic foot ulcers (DFU). For this reason, antibiotic treatment is often used in patients followed with DFU. Inappropriate use of antibiotics and increasing antibiotic resistance threaten public health. We aimed to investigate the microbial spectrum and antimicrobial resistance patterns isolated from diabetic foot infections in Turkey and help clinicians to choose optimal antibiotics empirically. Materials and Methods: This study was planned as a retrospective, single-center, cross-sectional study. Two hundred sixty-two patients whose causative microorganism was isolated in culture of tissue between 1 January 2021 and 31 December 2022 were included in this study. Bacterial profile and antimicrobial resistance patterns were analyzed. Results: Four hundred thirty two isolates from 262 patients isolated in culture of tissue were evaluated. Of these microorganisms, 57.60% were Gram-negative, 41.20% were Gram-positive bacteria, and 1.2% were Candida spp. The most frequently detected Gram-positive microorganism was Staphylococcus spp. Gram-negative microorganisms were Escherichia coli (E. coli) and Pseudomonas aeruginosa (P. aeruginosa). Polymicrobial infections were observed in 40.5% of the patients. Methicillin-resistant Staphylococcus spp. rate was 51.3%, while extended-spectrum beta-lactamase (ESBL) resistance for E. coli was 66.7%. Conclusions: Due to increasing antibiotic resistance rates, treatment of common infections becomes more difficult. Knowledge of the microbiological profile and antibiotic resistance patterns of patients with DFIs is useful to guide empirical therapy. [ABSTRACT FROM AUTHOR]

Background: Diabetic foot ulcers in developing countries often become infected. The healthcare systems are often not equipped to conduct the culture and the sensitivity tests required for prescribing a targeted antibiotic treatment for diabetic foot infection (DFI). Methods: We evaluate antibiotic stewardship programmes for DFIs, at every level of health care, with an emphasis on resource‐poor settings such as in Africa. Results: The management of DFI very often is adapted to the financial and practical realities of the resource‐poor regions. The application of the point‐of‐care Gram stain of deep tissue samples is efficient, rapid, low cost and ubiquitously available. Upon the identification of the predominant pathogen in the Gram stain, a semi‐quantitative preemptive antibiotic treatment can be started in accordance with the World Health Organization Aware, Watch and Restrict Essential Medicine List. This list is catered to every country and is a powerful tool. However, some basic knowledge of the local microbiological epidemiology is necessary to choose the most appropriate agent. We report our experience on using the rapidly available Gram stain for narrowing the preemptive choice of listed antibiotic agents, as an economic tool for antibiotic stewardship in DFIs. Conclusions: In the practical and resource‐saving management of DFI, the 'therapeutic' use of Gram stains is not common in resource‐rich countries but should be added to the arsenal of the general efforts for antibiotic stewardship.

Background: Diabetic foot osteomyelitis (DFO) is a major complication and can lead to significant morbidity and mortality. Systemic antibiotic therapy is often initiated first line to achieve quiescence of infection. To perform a multi-centre case review of systemic antibiotic intervention to treat adults with DFO in England and Wales and compare with national guidelines 'Diabetic foot problems: prevention and management'. Methods: Eight centres from England and Wales retrospectively collated data from a minimum of five adults (aged ≥ 18 years) from electronic case records. All patients were treated with systemic antibiotics following a new diagnosis of DFO (1 June 2021–31 December 2021). Results: 40 patients (35 males and 5 females) were included; the mean age was 62.3 years (standard deviation (SD) 13.0). Patients commenced systemic oral 14 (35%) or intravenous 26 (65%) antibiotic therapy following a new diagnosis of DFO. Twenty-seven (67.5%) patients were medically or surgically managed in the 12-week period with clinical quiescence of infection. Twenty-one patients (52.5%) had no recurrence of DFO infection within 12 weeks; seventeen (42.5%) of these patients had clinical quiescence of infection with systemic antibiotics alone without surgical intervention and nine (22.5%) of these cases had no recurrence of DFO. There were no cases of major amputation or death. All centres showed significant in-centre variability in systemic antibiotic management; variability was reported in the clinical and quantity indicators specifically to antibiotic selection, single versus dual therapy, mode of delivery and duration of treatment. Conclusions: This case review identifies there is existing variation when treating adults with systemic antibiotics for DFO. Further national guidance is required to standardise service delivery and care to improve patient outcomes. [ABSTRACT FROM AUTHOR]

A recent study examined the prescribing practices for diabetic foot infections (DFIs) in the United States. The study found that there was a high rate of discordant use of antipseudomonal therapy compared to the actual prevalence of Pseudomonas aeruginosa (PsA) in culture. Risk factors for PsA isolation included immunocompromised status and previous outpatient treatment failure. The study suggests that antimicrobial stewardship programs should focus on avoiding unnecessary antipseudomonal antibiotics and emphasizes the need for surgical interventions and preventative care in addition to empiric antibiotic treatment.

- Abstract
Severe lower extremity wounds have an increased risk of complications and limb loss. The aim of this study was to evaluate and compare the microbiological profile and antibiotic resistance of wounds in diabetic and nondiabetic patients. A cross-sectional comparative study was carried out at a public hospital including 111 patients with moderate to severe wound infections. Tissue samples were collected during a surgical procedure. One hundred and four patients (94%) had positive cultures and 88 (79%) had a Gram-negative microorganism. Among the 185 cultured microorganisms, 133 (72%) were Gram-negative species. Pseudomonas aeruginosa (23 cases) was the most isolated Gram-negative species, and Enterococcus faecalis (26 cases) was the most prevalent Gram-positive species. Among 185 isolated species, 45 (24%) were extended-spectrum beta-lactamase producers, 23 (12%) were carbapenem-resistant, and 5 (3%) were methicillin-resistant Staphylococcus aureus. Findings revealed that there was no significant difference in the microbiological profile and antibiotic resistance among patients with lower extremity wounds whether they were diabetic or nondiabetic.

Negative pressure wound therapy with instillation and dwell time (NPWTi-d) is increasingly used for a diverse range of wounds. Meanwhile, the topical wound irrigation solution consisting of polyhexamethylene biguanide and betaine (PHMB-B) has shown efficacy in managing wound infections. However, the effectiveness of this solution as a topical instillation solution for NPWTi-d in patients with diabetic foot infections (DFIs) has not been thoroughly studied. The objective of this retrospective study was to evaluate the impact of using PHMB-B as the instillation solution during NPWTi-d on reducing bioburden and improving clinical outcomes in patients with DFIs. Between January 2017 and December 2022, a series of patients with DFIs received treatment with NPWTi-d, using either PHMB-B or normal saline as the instillation solution. Data collected retrospectively included demographic information, baseline wound characteristics, and treatment outcomes. The study included 61 patients in the PHMB-B group and 73 patients in the normal saline group, all diagnosed with DFIs. In comparison to patients treated with normal saline, patients with PHMB-B exhibited no significant differences in terms of wound bed preparation time (P = 0.5034), length of hospital stay (P = 0.6783), NPWTi-d application times (P = 0.1458), duration of systematic antimicrobial administration (P = 0.3567), or overall cost of hospitalization (P = 0.6713). The findings of the study suggest that the use of either PHMB-B or normal saline as an instillation solution in NPWTi-d for DFIs shows promise and effectiveness, yet no clinical distinction was observed between the two solutions.

Introduction: Diabetic foot infection (DFI) is one of the complications of diabetes mellitus. Clindamycin (CLY) is one of the antibiotics recommended to treat DFI, but CLY given orally and intravenously still causes many side effects. Methods: In this study, we encapsulated CLY in a bacteria sensitive microparticle system (MP-CLY) using polycaprolactone (PCL) polymer. MP-CLY was then delivered in a separable effervescent microarray patch (MP-CLY-SEMAP), which has the ability to separate between the needle layer and separable layer due to the formation of air bubbles when interacting with interstitial fluid in the skin. Result: The characterization results of MP-CLY proved that CLY was encapsulated in large amounts as the amount of PCL polymer used increased, and there was no change in the chemical structure of CLY. In vitro release test results showed increased CLY release in media cultured with Staphylococcus aureus bacteria and showed controlled release. The characterization results of MPCLY-SEMAP showed that the developed formula has optimal mechanical and penetration capabilities and can separate in 56 ± 5.099 s. An ex vivo dermatokinetic test on a bacterially infected skin model showed an improvement of CLY dermatokinetic profile from MP-CLY SEMAP and a decrease in bacterial viability by 99.99%. Conclusion: This research offers proof of concept demonstrating the improved dermatokinetic profile of CLY encapsulated in a bacteria sensitive MP form and delivered via MP-CLY-SEMAP. The results of this research can be developed for future research by testing MP-CLY-SEMAP in vivo in appropriate animal models. [ABSTRACT FROM AUTHOR]

Abstract Background Diabetes‐related foot infections are common and represent a significant clinical challenge. There are scant data about outcomes from large cohorts. The purpose of this study was to report clinical outcomes from a large cohort of people with diabetes‐related foot infections. Methods A tertiary referral hospital limb preservation service database was established in 2018, and all new episodes of foot infections were captured prospectively using an electronic database (REDCap). People with foot infections between January 2018 and May 2023, for whom complete data were available on infection episodes, were included. Infection outcomes were compared between skin and soft tissue infections (SST‐DFI) and osteomyelitis (OM) using chi‐square tests. Results Data extraction identified 647 complete DFI episodes in 397 patients. The data set was divided into two cohorts identifying each infection episode and its severity as either SST‐DFI (N = 326, 50%) or OM (N = 321, 50%). Most infection presentations were classified as being moderate (PEDIS 3 = 327, 51%), with 36% mild (PEDIS 2 = 239) and 13% severe (PEDIS 4 = 81). Infection resolution occurred in 69% (n = 449) of episodes with failure in 31% (n = 198). Infection failures were more common with OM than SST‐DFI (OM = 140, 71% vs. SST‐DFI = 58, 29%, p

BackgroundDiabetic foot infection represents a significant complication of diabetes mellitus, contributing substantially to morbidity, mortality, and healthcare expenditure worldwide. Accurate diagnosis relies on a comprehensive assessment integrating clinical evaluation, imaging studies, and microbiological analysis. Management necessitates a multidisciplinary approach, encompassing surgical intervention, antimicrobial therapy, and advanced wound care strategies. Preventive measures are paramount in reducing the incidence and severity, emphasizing patient education, regular foot screenings, and early intervention.MethodsThe researchers performed a systematic review of literature using PUBMED MESH keywords. Additionally, the study was registered in the International Prospective Register of Systematic Reviews at the Center for Reviews and Dissemination, University of York (CRD42021277788). This review provides a comprehensive overview of the microbial spectrum and antibiotic susceptibility patterns observed in diabetic foot infections.ResultsThe search through the databases finally identified 13 articles with 2545 patients from 2021 to 2023. Overall, the predominant Gram-positive microbial species isolated were Staphylococcus aureus, Enterococcus fecalis, Streptococcus pyogenes, Streptococcus agalactiae, and Staphylococcus epidermidis. Whereas the predominant Gram-negative included Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis and Pseudomonas aeruginosa.ConclusionDiabetic foot infections represent a complex and multifaceted clinical entity, necessitating a holistic approach to diagnosis, management, and prevention. Limited high-quality research data on outcomes and the effectiveness of guideline recommendations pose challenges in updating and refining existing DFI management guidelines.Systematic review registrationhttps://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42021277788, identifier CRD42021277788.

Background: The eosinophil level in peripheral blood increases in response to various conditions, the most common being medication use. Since the outcome of increased levels of eosinophils can range from a benign finding to extensive damage to host organs and systemic consequences, this finding raises concern among clinicians. We aimed to assess the prevalence of prolonged antibiotic-therapy-induced eosinophilia and possible outcomes. Methods: We conducted a retrospective cohort study of diabetic patients admitted to the orthopedic department from December 2016 through December 2020 due to a moderate to severe diabetic foot infection and who received at least 14 days of antibiotic therapy. Patients were identified retrospectively through the orthopedic department registry, and their files were reviewed, extracting demographics, laboratory test results, antibiotic treatment, and outcomes. Results: The cohort included 347 patients; a total of 114 (32.8%) developed eosinophilia during the follow-up period. Patients who developed eosinophilia had a significantly longer duration of antibiotic treatment (p < 0.001) and a significantly longer hospitalization (p = 0.001). For multivariable analysis, the independent risk factors predicting drug-induced eosinophilia included older age, higher eosinophil count on admission (per quantile) and higher platelet count on admission (per quantile) (p = 0.012, p < 0.001, p = 0.009, respectively). There was no evidence of complications in patients who developed eosinophilia compared to patients who did not. No significant association with a specific type of antibiotic was found. Conclusions: We found a higher incidence of drug-induced eosinophilia than expected or previously described. The factors associated with eosinophilia included age and higher baseline eosinophil and platelet levels but not antibiotic type. [ABSTRACT FROM AUTHOR]

Background: This study aims to assess the atherogenic index of plasma (AIP) diagnostic value in detecting diabetic foot osteomyelitis (DFO) among patients with diabetic foot ulcers (DFUs). Methods: A prospective cohort study was conducted on 80 patients with DFUs and suspected DFO between January 2022 and December 2023. The primary outcome measures included the diagnosis of DFO, determined by positive microbiological analysis results from bone samples and its correlation with the AIP. Receiver operating characteristic (ROC) curves were utilized to select the optimal diagnostic cut-off points for AIP and post hoc analysis was performed to evaluate the difference in the AIP for diagnosing DFO in patients with and without peripheral arterial disease (PAD). Results: The diagnostic potential for DFO in PAD patients of AIP-1 (Log TC/HDL) showed an AUC of 0.914 (p < 0.001 [0.832–0.996]), leading to a sensitivity of 83% and a specificity of 85%. By contrast, AIP-2 (Log TG/HDL) demonstrated a slightly lower AUC of 0.841 (p < 0.001 [0.716–0.967]), leading to a sensitivity of 76% and a specificity of 74%. Conclusions: The AIP tool, with its ideal blend of sensitivity and specificity, aids in predicting DFO effectively. Therefore, clinicians should consider using AIP for patients suffering from PAD and associated DFO. [ABSTRACT FROM AUTHOR]

Background: Diabetic foot infection (DFI) leads to poor prognosis and polymicrobial infections are usually the main cause. The study is to explore the microbiological distribution, antimicrobial drug susceptibility, and risk factors of polymicrobial infections in hospitalized patients with DFI. Methods: This retrospective study included 160 patients with DFI in Wagner's grades 2, 3, and 4. Deep necrotic tissue was used to acquire specimens for microbiological culture. VITEK-2 system and MALDI-TOF mass spectrometry were used to identify the bacterial isolates. The Kirby Bauer method was used for drug susceptibility tests. Results: A total of 202 pathogens were isolated. The proportion of gram-negative bacilli (GNB, 62.4%, 126 of 202) was higher than that of gram-positive cocci (GPC, 37.6%, 76 of 202). The most prevalent GPC was Staphylococcus aureus in every Wagner grade, while the most common GNB varied in different Wagner grades. Linezolid was the most effective antibiotic for GPC in different Wagner grades. Imipenem was the most effective antibiotic for GNB in Wagner grade 2. Amikacin was the most effective antibiotic for GNB in Wagner grades 3 and 4. Polymicrobial infections existed only in Wagner grades 3 and 4 and increased the risk of amputation (p < 0.01). History of antibiotics, duration of diabetic foot, CRP, and lower extremity arterial disease were the independent risk factors of polymicrobial infections (p < 0.05). Conclusions: Clinicians should adjust the antibiotic as needed based on the results of drug susceptibility and clinical treatment effect among different Wagner grades. Particular attention should be given to the treatment of polymicrobial infections. [ABSTRACT FROM AUTHOR]

- Abstract
Diabetic foot infection (DFI) is a common problem in patients with diabetic foot disease. Amputations and other complications of DFI lead to significant morbidity and mortality. The Society for Vascular Surgery (SVS)-WIfI (wound, ischemia, and foot infection) classification system can evaluate the benefit from revascularization and the risk of amputation in 1 and 3 years. We aimed to evaluate SVS-WIfI and Wagner-Meggitt (WM) prediction of DFI outcome, and to determine factors associated with major amputation and mortality rate. The patients with diabetes who presented between June 2018 and May 2020 with characteristics suggesting a more serious DFI or potential indications for hospitalization were reviewed in this cohort study. Demographic data, clinical characteristics, and type of revascularization were evaluated. One-year and 3-year amputation and mortality rates were the main outcomes. The grading of WM classification and the SVS-WIfI score were compared between amputation and nonamputation groups. Association between mortality and comorbidity were analyzed. One hundred and thirty-one patients admitted with DFI were included in study. And 73.28% had peripheral arterial disease (PAD). The 1-year and 3-year major amputation rates were 16.03% and 26.23%, respectively. Seventy-eight (59.54%) patients required minor amputation to control infection before revascularization. PAD (risk ratio [RR] 1.47: 95% confidence interval [CI] 1.29-1.67, P =.032), benefit from revascularization clinical stage 3 on SVS-WIfI score (RR 4.56: 95%CI 1.21-17.21, P = 0.007), and high WM classification score (RR 9.46: 95% CI 5.65-15.82, P < 0.001) were associated by multivariate analysis with high amputation rates. 1-year & 3-year amputation risk on SVS-WIfI score were not associated with amputation rates in DFI (P =.263 and.496). Only 9 (6.8%) patients were lost to follow up during the 3-year period. WM classification score, SVS-WIfI score on benefit from revascularization, and PAD were strongly associated with major amputation rates in patients with DFI. [ABSTRACT FROM AUTHOR]

ABSTRACT Background Diabetic foot ulcers in developing countries often become infected. The healthcare systems are often not equipped to conduct the culture and the sensitivity tests required for prescribing a targeted antibiotic treatment for diabetic foot infection (DFI). Methods We evaluate antibiotic stewardship programmes for DFIs, at every level of health care, with an emphasis on resource‐poor settings such as in Africa. Results The management of DFI very often is adapted to the financial and practical realities of the resource‐poor regions. The application of the point‐of‐care Gram stain of deep tissue samples is efficient, rapid, low cost and ubiquitously available. Upon the identification of the predominant pathogen in the Gram stain, a semi‐quantitative preemptive antibiotic treatment can be started in accordance with the World Health Organization Aware, Watch and Restrict Essential Medicine List. This list is catered to every country and is a powerful tool. However, some basic knowledge of the local microbiological epidemiology is necessary to choose the most appropriate agent. We report our experience on using the rapidly available Gram stain for narrowing the preemptive choice of listed antibiotic agents, as an economic tool for antibiotic stewardship in DFIs. Conclusions In the practical and resource‐saving management of DFI, the ‘therapeutic’ use of Gram stains is not common in resource‐rich countries but should be added to the arsenal of the general efforts for antibiotic stewardship.

Background: Type 2 Diabetes Mellitus (T2DM) stands as the foremost risk factor for infected foot ulcers, contributing to a myriad of chronic complications including cardiovascular, renal, neuropathic, vascular, and podiatric issues. Employing suitable antibiotic therapy becomes imperative in managing Diabetic Foot Infections (DFIs). This study endeavors to assess the efficacy of antibiotic treatment in addressing infected foot ulcers among patients with T2DM in Vietnam. Methods: A descriptive cross-sectional study with analysis was performed on 830 T2DM patients (67 patients with DFIs were treated with antibiotic therapy to evaluate treatment outcomes). Results: Among T2DM patients, 8.07 % had infected foot ulcers, with an average age of 62.5 ± 11 years and a female-to-male ratio of 2.9:1. Ulcer healing post-antibiotic treatment was 88.06 %, with 35.82 % aligning initial antibiotic treatment with antibiogram results. Bacterial resistance rates were high for Cephalosporin (>60 %), Ampicillin/Sulbactam (91.67 %), and Quinolone groups (>60 %), while Carbapenem group showed high sensitivity (>73 %). Initial empiric antibiotic treatment response was associated with osteomyelitis existence and ulcer healing outcomes (p 2, elevated CRP levels, and atherosclerotic stenosis were associated with lengthy clinic stays. Conclusion: Selecting the proper antibiotic regimen is crucial in effectively managing Type 2 Diabetic Foot Infections. Identifying the risk factors associated with treatment outcomes is imperative to mitigate adverse effects on foot infection treatment outcomes among T2DM patients in Vietnam.

Diabetic foot ulcers are hard to treat ulcers that are common in population. This situation causes amputations and extremity loss. Among therapeutic options negative pressure wound therapy (NPWT) seems a good option to treat specially non osteomyelitic and non ischemic wounds. This method can be widely used in deep, large and infected wounds. The antibacterial effect of silver on wounds has been used for centuries. Silver wound closure sets, which are also used in NPWT systems, have gained importance in recent years. In this study, the effect of Confort brand NPWT with and without silver on wound healing evaluated retrospectively. This is a multi center study involving five different institution. As a success criterion, a reduction of >50% in the initial dimensions of the wound (width/length/depth) after 7 applications is accepted. When the silver coated and standard foam Confort NPWT groups were compared, the reduction of 50% or more in the wound volume was relatively shorter in the silver group; while it was 3.2 +/- 1.2 weeks in the silver group, it was 5.14 +/- 2.3 weeks in the silver-free group (p=0.08).

Abstract Background Blinding drugs through simulation techniques is an important means to control the subjective bias of investigators and subjects. However, clinical trials face significant challenges in the placebo production of drugs, and many trials cannot be double-blinded. Objective This study was conducted to ascertain the consistency between non-blind and blind evaluation results in clinical trials and to pioneer strategies to control information bias, particularly in trials where double-blinding is not feasible. Methods In this investigation, a randomized controlled trial (RCT) studying diabetic foot infections (DFIs) was utilized as a representative case. In this trial, the grading of DFIs, as per guidelines by the Infectious Disease Society of America (IDSA) and International Working Group on Diabetic Foot (IWGDF), was used as the primary efficacy indicator. A sample of sixteen patients was randomly chosen from the RCT, and DFI grading was assessed jointly by both non-blinded investigators and blinded center-reading investigators. A consistency test was then deployed to compare the evaluation results, forming the basis for our proposed strategies for effective blinded evaluation. In addition, other perspectives were collected at the end of this study, including with those involved in designing and conducting the recent blinded evaluation trial. Results Five subjects were excluded due to the quality of photos or the lack of post-treatment visits. The post-treatment IDSA/IWGDF grading results were compared in 11 subjects (experimental group=6, control group=5), and the consistency test showed inconsistent results between the non-blinded and center reading blinded evaluations (Kappa=0.248, p=0.384). In the experimental group, three cases were judged as grade 1 in the non-blinded evaluation and grade 2 in the central reading blinded evaluation; in the control group, three cases were judged as grade 2 in the non-blinded evaluation and grade 1 in the central reading blinded evaluation. The sum of these two cases in 22 post-treatment determinations was 27% (6/22). Furthermore, researchers propose several strategies for implementing blinded evaluations in clinical trials after this trial, which encompass aspects such as staff allocation, training, participant management, trial drug administration, efficacy indicator collection, and safety event management. Conclusions The study highlighted that evaluations from non-blinded site investigators may potentially exaggerate the efficacy of the experimental group and that deep wounds can present challenges for observation via center-reading photos. These findings underline the vital necessity for objective assessment in open clinical trials, especially those where wound observation serves as the primary efficacy indicator. The study suggests the adoption of independent blinded investigators at each site, complemented by a comprehensive set of standard operating procedures for blinding evaluation. These measures could serve as an effective counterbalance to subjective bias, thereby augmenting the credibility and consistency of results in open clinical trials. The implications of these findings and recommendations could be of great significance for the design and execution of future open clinical trials, potentially bolstering the quality of clinical research in this area.

Diabetes Mellitus (DM) is a significant global concern. Many diabetic patients will experience complications due to angiopathy, neuropathy, and immune dysfunction, namely diabetic foot ulcers (DFU) and diabetic foot infections (DFI), which can result in lower limb amputation and potentially death. The prevalence of common superficial fungal infections, such as tinea pedis and onychomycosis, can directly increase a diabetic patient’s risk of developing both DFU and DFI. In this review article, we discuss the etiology of diabetic foot complications as well as considerations for both screening and management. We also discuss the role of the dermatologist within a multidisciplinary care team in prescribing and managing treatments for tinea pedis and onychomycosis infections within this patient population. We believe that reducing the burden of these fungal infections in the context of the diabetic foot will help reduce DFU and DFI complications and their associated morbidity and mortality.

BackgroundDiabetic foot infections (DFIs) are commonly associated with antibiotic overuse. Empiric DFI treatment often includes coverage for Pseudomonas aeruginosa (PsA), but the frequency of PsA DFIs is poorly understood. The study objectives were to quantify the prevalence of and determine predictors for PsA DFIs.MethodsThis multicenter, retrospective cohort included hospitalized patients with DFI from 2013 through 2020 who were age ≥18 years; diabetes mellitus diagnosis; and DFI based on International Classification of Diseases, Tenth Revision coding, antibiotic treatment, and DFI culture with organism growth. Osteomyelitis was excluded. Patient characteristics were described and compared; the primary outcome was presence of PsA on DFI culture. Predictors of PsA DFI were identified using multivariable logistic regression.ResultsTwo hundred ninety-two patients were included. The median age was 61 (interquartile range [IQR], 53-69) years; the majority were men (201 [69%]) and White (163 [56%]). The most commonly isolated organisms were methicillin-susceptible Staphylococcus aureus (35%) and streptococci (32%); 147 (54%) cultures were polymicrobial. Two hundred fifty-seven (88%) patients received empiric antibiotics active against PsA, but only 27 (9%) patients had PsA DFI. Immunocompromised status (adjusted odds ratio [aOR], 4.6 [95% confidence interval {CI}, 1.3-16.7]) and previous outpatient DFI antibiotic treatment failure (aOR, 4.8 [95% CI, 1.9-11.9]) were associated with PsA DFI.ConclusionsPsA DFI is uncommon, but most patients receive empiric antipseudomonal antibiotics. Empiric broad-spectrum antibiotics are warranted given the frequency of mixed infections, but patient-specific risk factors should be considered before adding antipseudomonal coverage.

The treatment of severe diabetic toe infection complicated with osteomyelitis is often surgical. The decision on the level of amputation, when required, is difficult. Very few articles reported comparative outcomes between toe amputation and ray resection, and only in relation to the hallux. The aim of this preliminary report is to record the results of these procedures when performed on all toes. This is a comparative retrospective study where the charts of a continuous series of 44 patients (48 procedures) with diabetic forefoot infection were analyzed. Only cases of severe infection with confirmed osteomyelitis were included. Two groups were compared based on the level of amputation: the toe amputation group (at and distal to the metatarsophalangeal joint) and the ray resection group (distal to tarsometatarsal joint). The primary outcomes were defined as osteomyelitis recurrence and re-amputation. Outcome comparison between toe amputation and ray resection; 47.3 % vs. 51.7 % had a recurrence of their osteomyelitis (p = 0.8), 36.8 % vs. 34.5 % had a re-amputation (p = 0.02). Re-amputation was needed in 25 % of cases following hallux/first ray index procedure while the same was required in 39 % of cases following lateral toes/rays index procedures (p = 0.4). Both primary outcomes were correlated to CDK, smoking and creatinine level. Bone infection recurrence and re-amputation are highly prevalent in patients undergoing initial amputation for severe diabetic toe infection. A more aggressive approach in the form of a more proximal level of index amputation might be needed when treating severe toe infections with osteomyelitis in patients with diabetes.

- Abstract
Foot infections are the most prevalent problem in persons with diabetes. The burden of multidrug resistant (MDR) microorganisms in diabetic foot infections (DFIs) is rising day by day. Given that, the present study aims to determine the variety of microorganisms isolated from the diabetic foot ulcers (DFUs), and their antibiotic sensitivity pattern. This prospective observational study was conducted for 1 year at Bharati Hospital and Research Centre, Pune, India. Clinically infected patients with DFU admitted to the surgery ward were included in this study. The specimen for microbiological studies is obtained from the wound swabs, soft tissue, and bone tissue as a part of routine clinical care. All demographic, clinical data, microbial culture results were collected, and evaluated for each case. Antimicrobial susceptibility testing to different agents was carried out using the VITEK-2
® machine. A total of 110 microorganisms were isolated from 76 specimens, with an average of 1.4 organisms per lesion. Staphylococcus aureus (n = 27, 24.5%) and Escherichia coli (n = 17, 15.4%) were the most prevalent Gram-positive and Gram-negative organisms isolated, respectively. MDR organisms constituted up to 52 (47.2%), while 6 (5.4%) of the samples were extensively drug resistant (XDR). Methicillin-resistant S aureus (MRSA) accounted for up to 19 (70.3%) of the S aureus isolates, likewise extended-spectrum beta-lactamase producing microorganisms constituted 16 (14.5%) of total isolates in this study. Oxacillin and benzyl penicillin exhibited least susceptibility against Gram-positive bacteria, among Gram-negative organisms; cefuroxime, ceftriaxone, and ciprofloxacin were least sensitive. As most of the S aureus isolate in our study was MRSA, empirical antimicrobial therapy may include coverage for MRSA in a patient with risk factors associated with this pathogen. A crucial observation is the presence of XDR strains of Proteus mirabilis in DFIs, which is resistant to almost all the antimicrobials, tested. Appropriate antimicrobial selection may reduce the morbidity and the emergence of MDR organisms in DFIs. [ABSTRACT FROM AUTHOR]- Published
