Abstract We identified deep diabetic foot infections by culture and conducted a case–control study examining the risk factors for moderate to severe methicillin-resistant Staphylococcus aureus (MRSA) and Pseudomonas aeruginosa (PsA) diabetic foot infections. Our MRSA prevalence was lower than literature values; PsA was higher. Gangrene may be predictive of Pseudomonas infection.

Chronic Wound Infections

Abstract Background: Pseudomonas aeruginosa is the most common Gram-negative pathogen responsible for chronic wound infections, such as diabetic foot infections, and further exacerbates the treatment options and cost of such conditions. Hypertonic glucose, a commonly used prolotherapy solution, can accelerate the proliferation of granulation tissue and improve microcirculation in wounds. However, the action of hypertonic glucose on bacterial pathogens that infect wounds is unclear. In this study, we investigated the inhibitory effects of hypertonic glucose on multidrug-resistant P. aeruginosa strains isolated from diabetic foot infections. Hypertonic glucose represents a novel approach to control chronic wound infections caused by P. aeruginosa. Results: Four multidrug-resistant P. aeruginosa clinical strains isolated from diabetic foot ulcers from a tertiary hospital in China and the reference P. aeruginosa PAO1 strain were studied. Hypertonic glucose significantly inhibited the growth, biofilm formation, and swimming motility of P. aeruginosa clinical strains and PAO1. Furthermore, hypertonic glucose significantly reduced the production of pyocyanin and elastase virulence factors in P. aeruginosa. The expression of major quorum sensing genes (lasI, lasR, rhlI, and rhlR) in P. aeruginosa were all downregulated in response to hypertonic glucose treatment. In a Galleria mellonella larvae infection model, the administration of hypertonic glucose was shown to increase the survival rates of larvae infected by P. aeruginosa strains (3/5).Conclusions: Hypertonic glucose inhibited the growth, biofilm formation, and swimming motility of P. aeruginosa, as well as reduced the production of virulence factors and quorum sensing gene expression. Further studies that investigate hypertonic glucose therapy should be considered in treating chronic wound infections.

Background: Selecting empirical therapy for a diabetic foot infection (DFI) requires knowing how likely infection with Pseudomonas aeruginosa is in a particular patient. We designed this study to define the risk factors associated with P aeruginosa in DFI. Methods: We performed a preplanned microbiological subanalysis of data from a study assessing the effects of treatment with intralesional epidermal growth factor for diabetic foot wounds in patients in Turkey between January 1, 2012, and December 31, 2013. Patients were screened for risk factors, and the data of enrolled individuals were recorded in custom-designed patient data forms. Factors affecting P aeruginosa isolation were evaluated by univariate and multivariate logistic regression analyses, with statistical significance set at P < .05. Results: There were 174 patients enrolled in the main study. Statistical analysis was performed in 90 evaluable patients for whom we had microbiological assessments. Cultures were sterile in 19 patients, and 89 bacterial isolates were found in the other 71. The most frequently isolated bacteria were P aeruginosa (n = 23, 25.8%) and Staphylococcus aureus (n = 12, 13.5%). Previous lower-extremity amputation and a history of using active wound dressings were the only statistically significant independent risk factors for the isolation of P aeruginosa in these DFIs. Conclusions: This retrospective study provides some information on risk factors for infection with this difficult pathogen in patients with DFI. We need prospective studies in various parts of the world to better define this issue.

ABSTRACT Against 182 anaerobe and 241 aerobe strains obtained from diabetic foot infections, doripenem was the most active carbapenem against Pseudomonas aeruginosa (MIC90, 2 μg/ml), more active than imipenem against Proteus mirabilis, and ertapenem was more active against Escherichia coli and Klebsiella spp. The MIC50 and MIC90 values were ≤0.125 μg/ml for methicillin-sensitive Staphylococcus aureus and all streptococci and 0.25/1 for Bacteroides fragilis.

Objectives: Describe the epidemiology of diabetic foot infections in Lebanon as well as the demographic and clinical characteristics of the patients. Study the microbiology of the infections and the bacterial resistances in the infected diabetic foot ulcers, in order to help reach an optimal care in the healthcare establishments. Materials and methods: A retrospective study between January, 2000 and Mars, 2011 of medical cases of 167 hospitalized patients for diabetic foot infection at the Hospital Hôtel-Dieu of France in Beirut, Lebanon. Results: The average age of the patients was 66 years, and males represented 73.65 %. The duration of diabetes was 20 years with a percentage of HbA1C >7 % in 79 % of the cases. 73.17 % of the patients had peripheral arteriopathy, 72.3 % peripheral neuropathy. Other complications of diabetes were associated: coronary problems (49.69 %), retinopathy (48.67 %) and renal disease (47.65 %). High blood pressure was found in 60.38 % of the cases, dyslipidemia in 48.73 %. Pseudomonas aeruginosa was the most frequently isolated bacteria from diabetic foot infections (19.15 %), followed by Escherichia coli (11.91 %), Staphyloccocus aureus (11.06 %), and of Enteroccocus fecalis (11.06 %). Most prescribed antibiotics were: pipéracllin/tazobactam, amoxicillin/clavulanic acid, and imipenme. Amputation was necessary in 36.3 % of the cases. The main risk factors of amputation, besides the infection itself, were history of amputation and arteriopathy Conclusion: In the Lebanese population, the diabetic foot disease takes the aspect of pathology with male ascendancy, which affects, late in their lives, patients with a long-time, badly controlled diabetes. Often, several complications of diabetes are present associated, in particular arteriopathy and peripheral neuropathy. Pseudomonas aeruginosa was the most frequently isolated bacteria from diabetic foot infections in Lebanon. The amputation rate remains high: 36.3 %, with arteriopathy and history of amputation as risk factors.
