Comparative Evaluation of the Diagnostic Value of Procalcitonin and hsCRP for the Presence of Mild-to-Moderate Diabetic Foot Infections

The aim of this study is to compare the efficacy of procalcitonin (PCT) and high-sensitive C-reactive protein (hsCRP) as diagnostic biomarkers in patients with diabetes and mild-to-moderate diabetic foot infections. A total of 119 patients (102 with type 2 diabetes and 17 with type 1 diabetes), of mean age 60.29 ± 10.05 years, divided into 3 groups—diabetic foot ulcer (DFU) with active infection (IDFU group, n = 41), DFU without clinical signs of infection (non-IDFU group, n = 35), and a control group with diabetes without DFU (n = 43). Infection severity was graded according to the International Working Group on the Diabetic Foot guideline—non-IDFU group as Grade 1, IDFU group as Grade 2 (n = 22), and Grade 3 (n = 19). Serum hsCRP was assessed by the immunoturbidimetric method and PCT by the enzyme chemiluminescence immunoassay (ECLIA) method. Levels of white blood cells (WBC) were assessed using the Medonic hematology analyzer and erythrocyte sedimentation rate (ESR) by the Westergren method. Serum hsCRP, WBC count, and ESR were significantly higher in the IDFU group as compared to non-IDFU and control groups, whereas PCT levels did not differ between the groups. hsCRP presented with higher sensitivity (80%), specificity (79%), area under the curve (AUC) 0.856, in comparison to PCT (sensitivity 63%, specificity 62%, AUC 0.617) for the presence of IDFU, as well as in the Grade 3 subgroup (84% sensitivity and specificity, AUC 0.911). The combined model of both markers did not present with better accuracy than using hsCRP alone. In conclusion, hsCRP appears to be a better diagnostic biomarker than PCT in the diagnosis of moderate foot ulcer infection. Both markers fail to distinguish mild infection.

Aims. To examine whether fibrinogen levels are a valuable biomarker for assessing disease severity and monitoring disease progression in patients with diabetic foot ulcer (DFU).Methods. A retrospective study was designed to examine the utility of fibrinogen in estimating disease severity in patients with DFU admitted to our hospital between January 2015 and January 2016. In total, 152 patients with DFU were enrolled in the study group, and 52 age and gender matched people with diabetes but no DFU were included as the control group. DFU severity was assessed using Wagner criteria.Results. Patients with DFU were divided into 2 subgroups based on the Wagner criteria. Mean fibrinogen values were significantly higher in patients with DFU grade ≧ 3 compared to those with DFU grades 1-2 (5.23 ± 1.37 g/L versus 3.61 ± 1.04 g/L). Using ROC statistic, a cut-off value of 5.13 g/L indicated the possible amputation with a sensitivity of 81.8% and a specificity of 78.9% (positive predictive value [PPV] 78.6%, negative predictive value [89.0%]). Fibrinogen values were found to be correlated with CRP levels, neutrophil, and WBC count.Conclusions. Fibrinogen levels might be a valuable tool for assessing the disease severity and monitoring the disease progression in patients with DFU.

Background:Diabetic foot ulcer (DFU) is one of the most common complications of diabetic patients. Mostly, non-healing DFU leads to infection, gangrene, amputation and even death. High costs and poor healing of the wounds need a new treatment such as alternative medicine. So, the aim of this study was to evaluate the efficacy of Aloe vera/ Plantago major gel (Plantavera gel) in healing of DFUMethods:Forty patients with DFU enrolled in a double-blind randomized clinical trial. The patients who were randomly assigned into the intervention group (n = 20), received topical Plantavera gel in addition to the routine cares, whereas the patients in the control group (n = 20), received topical Placebo gel in addition to the routine cares. Intervention was done twice a day for 4 weeks in the both groups. Photography and an evaluation of DFU healing were conducted by a checklist and then were scored at baseline and at the end of each week. The collected data was analyzed by SPSS software.Results:At the end of the study, there was a significant difference between the two groups in terms of total ulcer score (P<0.001) and Plantavera gel significantly reduced the ulcer surface comparing with the control group (P=0.039). However, there was not a significant difference between the two groups (P=0.263) in terms of the ulcer depth. During this study, no side effect was observed for Plantavera gel in the intervention group.Conclusion:Topical Plantavera gel seems to be an effective, cheap and safe treatment. Of course, further studies are required to confirm the properties of the wound healing of this gel.

Diabetic foot ulcers (DFUs) are a serious complication in diabetic patients and lead to high morbidity and mortality. Numerous dressings have been developed to facilitate wound healing of DFUs. This study investigated the wound healing efficacy of silver-releasing foam dressings versus silver-containing cream in managing outpatients with DFUs. Sixty patients with Wagner Grade 1 to 2 DFUs were recruited. The treatment group received silver-releasing foam dressing (Biatain® Ag Non-Adhesive Foam dressing; Coloplast, Humlebaek, Denmark). The control group received 1% silver sulfadiazine (SSD) cream. The ulcer area in the silver foam group was significantly reduced compared with that in the SSD group after four weeks of treatment (silver foam group: 76.43 ± 7.41%, SSD group: 27.00 ± 4.95%, p < 0.001). The weekly wound healing rate in the silver foam group was superior to the SSD group during the first three weeks of treatment (p < 0.05). The silver-releasing foam dressing is more effective than SSD in promoting wound healing of DFUs. The effect is more pronounced in the initial three weeks of the treatment. Thus, silver-releasing foam could be an effective wound dressing for DFUs, mainly in the early period of wound management.

Abstract Background In 2018, a review of the scientific literature identifed biofilm studies in the past 3 years. Wherein, the role of the biofilm in the progression of the diabetic foot ulcer with the presence of biofilm is reviewed. As a result, tissue sampling is more effective than transcure, Levin, and aspiration. A study in Cuba evaluate the effectiveness of a new proposal for antimicrobial treatment in patients with diabetic foot infection in 2017. The method used was a experimental type of two groups. The control group, was treated with the treatment scheme proposed in the Comprehensive Care Program for the patient with diabetic foot ulcer (PAIPUPD). Instead, the other experimental group was treated according to the scheme based on the local microbial map. They used a random distribution. Using the Wagner classification, there were patients classificate with a grade of W2 (13% of patients), W3 (66%) and W4 (12%). The most frequent germs found were Staphylococcus aureus, Escherichia coli and Enterobacter sp. The experimental group required less days with hospitalization. Methods This is an observational study of primary source with a non-probability sample with 58 patients. Adult patients diagnosed with type 2 diabetes mellitus, with diabetic foot, Wagner classification 1, 2 and 3, who attended the healing area of the Institute of Diabetes of Santiago were included. After identifying the colonized pathogen, its cicatrization process was evaluate for four weeks. Results Of the total sample, 12.07% belonged to Wagner 1, 43.1% to Wagner 2 and 44.83% to the Wagner 3 classification. In the case of the Wagner 3 group, S. aureus and Pseudomona aeruginosa were present in 6 cases. Despite the infectious processes detected by the culture, the patients showed a successful cicatrization process after four weeks of evaluation. Graph 1: Isolated Microorganism Vs Wagner’s Degree (n=60) Graph 2: Gram positive microorganism vs. healing process per week in patients with diabetic foot (n=22) Graph 3: Gram-negative microorganism vs. healing process (n=33) Conclusion During the four weeks of clinical evaluation, more than 88% of patients progressed positively to clinical recovery, regardless of the type of bacteria colonized and/or their resistance to antibiotics.

Background The objective of this study was to create an algorithm that could predict diabetic foot ulcer (DFU) incidence in the in-patient population. Materials and Methods The Nationwide Inpatient Sample datasets were examined from 2008 to 2014. The International Classification of Diseases 9th Edition Clinical Modification (ICD-9-CM) and the Agency for Healthcare Research and Quality comorbidity codes were used to assist in the data collection. Chi-square testing was conducted, using variables that positively correlated with DFUs. For descriptive statistics, the Student T-test, Wilcoxon rank sum test, and chi-square test were used. There were six predictive variables that were identified. A decision tree model CTREE was utilized to help develop an algorithm. Results 326,853 patients were noted to have DFU. The major variables that contributed to this diagnosis (both with p < 0.001) were cellulitis (OR 63.87, 95% CI [63.87–64.49]) and Charcot joint (OR 25.64, 95% CI [25.09–26.20]). The model performance of the six-variable testing data was 79.5% (80.6% sensitivity and 78.3% specificity). The area under the curve (AUC) for the 6-variable model was 0.88. Conclusion We developed an algorithm with a 79.8% accuracy that could predict the likelihood of developing a DFU.

Abstract: Diabetic foot ulcer (DFU) is still a health problem related to the extent amount of time in wound healing process hence increasing the treatment cost. Given any methods that are not sat-isfying, encourage the search of other methods that would increase the wound healing rate, in which hyperbaric oxygen therapy (HBOT) is amongst them. The DFU patient that receives HBOT shows a significant increase in angiogenesis process markedly by faster epithelialization and granulation process. This study was aimed to prove that HBOT could accelerate the wound healing process among DFU patients measured by wound size and depth of PEDIS score. This was a ran-domized controlled trial study, conducted at Surgery Department of Prof. Dr. R. D. Kandou Gen-eral Hospital from September 2018 to March 2019. There were 20 DFU patients divided into two groups, each of 10 patients. The control group received a holistic treatment, meanwhile the HBOT group received a holistic treatment added with the inclusion of HBOT. PEDIS score assessment of DFU in HBOT group was measured before and after the third HBOT session, meanwhile the con-trol group was measured on the first and the third day. The results showed that the difference in PEDIS score value was markedly found in HBOT group compared to the control group (2 vs. 0, P=0.001). Conclusion: HBOT could enhance the wound healing process in DFU patients based on the declined PEDIS score.Keywords: HBOT, PEDIS score, diabetic foot ulcerAbstrak: Ulkus kaki diabetik (UKD) masih merupakan masalah kesehatan terkait proses penyembuhan lama sehingga biaya pengobatan meningkat. Belum adanya metode penanganan yang memuaskan, mendorong pencarian metode percepatan penyembuhan luka, salah satunya ialah terapi oksigen hiperbarik (TOHB). Penderita UKD yang menjalani tambahan TOHB diketahui mengalami peningkatan proses angiogenesis yang menghasilkan proses epitelialisasi dan granulasi yang lebih cepat. Tujuan penelitian ialah untuk membuktikan bahwa TOHB dapat mempercepat proses penyembuhan UKD, dinilai berdasarkan ukuran dan kedalaman luka melalui skor PEDIS. Penelitian ini menggunakan randomized controlled trial dan dilaksanakan di Bagian Bedah RSUP Prof. Dr. R.D. Kandou Manado sejak September 2018 sampai dengan Maret 2019. Subyek penelitian sebanyak 20 penderita UKD, dibagi dalam dua kelompok, masing-masing 10 penderita. Kelompok kontrol menjalani penanganan holistik UKD, sedangkan kelompok TOHB menjalani penanganan holistik UKD dengan TOHB. Penilaian skor PEDIS terhadap UKD pada kelompok TOHB dilakukan sebelum dan sesudah TOHB sesi ke-3, sedangkan pada kelompok kontrol dilakukan penilaian pada hari ke-1 dan hari ke-3 sesudahnya. Hasil penelitian mendapatkan bahwa perubahan skor PEDIS yang terjadi antara kedua pengukuran terlihat lebih besar pada kelompok TOHB dibandingkan kelompok kontrol (2 vs 0, P=0,001). Simpulan. TOHB mempercepat proses penyembuhan UKD dinilai dari penurunan skor PEDIS.Kata kunci: TOHB, skor PEDIS, ulkus kaki diabetik

Objective: (1) To evaluate the effects of G-CSF in eliminating infection in diabetic foot wound (2) Tocompare the effects with conventional diabetic foot management. Design: Prospective, open, randomized comparativestudy. Setting: Medical&Surgical Department of Allied, DHQ Hospital & Nawaz Medicare Faisalabad. Period: FromJan 2000 to Nov 2000 Patients & Methods: Fifty diabetic patients with foot infections were included in this study. Themean age was 52 years ranging from 27 to 60 years. They were divided into two equal groups(Group A and Group B).Results: The male patients were 41(82%) and female 9(18%). Forty six percent of patients were on oral hypoglycaemicdrugs, and 54% on insulin. The trauma preceding infection was 20%, Peripheral neuropathy 94% and peripheralvascular disease 34%. Thirty two percent of patients were smoker. Group A were subjected to G-CSF ( Neupogen )therapy (n=25) subcutanously daily for 5days in addition to conventional measures. Whereas patients in Group Breceived only conventional therapy. Both groups received similar antibiotic and insulin treatment. G-CSF therapy wasassociated with earlier eradication of pathogens from the infected ulcer (median 5 [range 2-11] vs11 [6-31] days in thegroup B; (p=<O.000I), quicker resolution of cellulitis (6 vs l4 days; p<O.0001), shorter hospital stay (8 vsl6 days;p<O.000l), and a shorter duration of intravenous antibiotic treatment (7 vs l4 days ;p—0.0001).No G-CSF treatedpatient needed surgery, whereas three patients in group B underwent toe amputation and six had extensivedebridement under anaesthesia (p=0.00 1). G-CSF therapy was generally well tolerated. Conclusion: Granulocytecolony stimulating factor (G-CSF) may be used as a good adjuvant therapy along with conventional measures for themanagement of diabetic foot infection, as it promotes the healing of diabetic foot ulcer/cellulitis and consequentlyprevents many hazardous complications like amputation of limbs, long hospital stays, extensive and prolonged antibioticuse and last but not the least the total misery of the patients.

Diabetic Foot Infections

Diabetic foot infection (DFI) is an important risk factor for amputation, and late diagnosis or referral is often incriminated for poor outcome. To enable an earlier diagnosis of DFI, comparative foot thermometry has been suggested as a self-screening method for patients in a home setting. We validated the efficacy of the ThermoScale, a weighing scale outfitted with temperature sensors that allows accurate temperature measurement in both feet. Temperature differentials in DFI patients (n = 52) were compared with a control group of similar diabetic patients (n = 45) without any foot wounds. Based on these findings, we drafted a receiver operating characteristic curve to determine an area-under-the-curve of 0.8455. This value suggests that the ThermoScale, as a diagnostic test, is reasonably accurate. A cutoff value of 2.15 °C temperature difference corresponded with a sensitivity of 88.9% and a specificity of 61.5%. As wearables, portable health electronics, and telemedicine become increasingly popular, we think that comparative temperature measurement technology is valuable in improving early diagnosis of DFIs.

Diabetic foot ulcer (DFU) is a common complication of type 2 diabetes mellitus (T2DM) characterized by ulcer formation, which can lead to the amputation of lower extremities. However, the metabolic alterations related to this complication are not completely elucidated. Therefore, we carried out a metabolomic analysis of serum samples obtained from T2DM adult patients diagnosed with diabetic foot ulcer in a cross-sectional, observational, and comparative study. Eighty-four volunteers were classified into the following groups: without T2DM (control group, n = 30) and with T2DM and different stages of diabetic foot ulcer according to Wagner-Meggitt classification system: DFU G0 (n = 11), DFU G1 (n = 14), DFU G2 (n = 16), and DFU G3 (n = 13). The non-target metabolomic profile followed by chemometric analysis revealed that lysophosphatidylethanolamine (16:1) could be proposed as key metabolite related to the onset of diabetic foot ulcer; however, this phospholipid was not affected by diabetic foot ulcer progression. Therefore, further studies are necessary to validate these phospholipids as biomarker candidates for the early diagnosis of diabetic foot ulcer in T2DM patients.

Diabetic Foot Infections

Background: This study investigated the resistance of bacteria isolated from diabetic foot ulcers (DFUs) to antibiotics frequently used in the management of the diabetic foot infections, at a range of pH values (pH 6.5, 7.5, and 8.5) known to exist in DFU wound fluid. This study aimed to determine whether changes (or atypical stasis) in wound fluid pH modulate the antibiotic resistance of DFU isolates, with potential implications in relation to the suppression/eradication of bacterial infections in DFUs. Methods: Thirty bacterial isolates were recovered from DFU wound fluid, including Staphylococcus spp, Staphylococcus aureus, Escherichia coli, Streptococcus spp, Pseudomonas spp, and Pseudomonas aeruginosa. The resistances of these isolates to a panel of antibiotics currently used in the treatment of infected or potentially infected DFUs, ie, ciprofloxacin, amoxicillin-clavulanate, doxycycline, and piperacillin-tazobactam, at the previously mentioned pH values were determined by a modification of the Kirby-Bauer assay. Results: The resistance of DFU isolates to clinically relevant antibiotics was significantly affected by the pH levels in DFU wound fluid. Conclusions: These findings highlight the importance of a more comprehensive understanding of the conditions in DFUs to inform clinical decision making in the selection and application of antibiotics in treating these difficult-to-heal wounds. The scale of the differences in the efficacies of antibiotics at the different pH values examined is likely to be sufficient to suggest reconsideration of the antibiotics of choice in the treatment of DFU infection.
