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.

To evaluate the actual burden of methicillin-resistant Staphylococcus aureus and determine risk factors for carriage and infection, we performed a prevalence survey with a nested case-control study among inpatients in Dutch hospitals. The prevalence of carriage was 0.94 cases per 1,000 inpatients, and the prevalence of infection was 0.21 cases per 1,000 inPatients. Professional contact with livestock and a stay in a foreign hospital were associated with carriage.

Introduction: The emergence of strains of methicillin-resistant Staphylococcus aureus is a serious therapeutic challenge in healthcare provision. With this study, we aimed to investigate the risk factors and clinical outcomes (mortality and length of hospital stay) associated with methicillin-resistant Staphylococcus aureus infections in patients admitted to a district hospital in Portugal.Material and Methods: A case-control study was performed in 96 cases and 122 controls, selected, respectively, as function of antibiotic resistance or sensitivity to methicillin. Data were obtained through consultation of clinical records and subjected to multivariate statistical analysis.Results: We identified the following independent risk factors for the occurrence of methicillin-resistant Staphylococcus aureus infection: urinary catheter (aOR = 10.62, 95% CI 3.66 – 30.78), prior use of antibiotics in the last 30 days (aOR = 5.60, 95% CI 2.15 – 14.62), exposure to 5 - 7 days of hospitalization (aOR = 4.99, 95% CI 1.20 – 20.79) or to ≥ 8 days (aOR = 5.34, 95% CI 1.18 – 24.22), chronic obstructive pulmonary disease (aOR = 4.27, 95% CI 1.64 – 11.13) and recent hospitalization (aOR = 2.66, 95% CI 1.14 – 6.23). Compared to infections due to methicillin-susceptible Staphylococcus aureus, we found increased probability of having a longer hospital stay (aHR = 1.74, 95% CI 1.11 – 2.71) and in-hospital mortality was significantly higher (p = 0.001) between patients infected by methicillin-resistant Staphylococcus aureus.Discussion: The results demonstrate that methicillin resistance is associated with an increased clinical risk to patients infected by Staphylococcus aureus, in particular, a raised mortality and prolonged hospitalization.Conclusion: Our study underlines the additional burden imposed by methicillin resistance in Staphylococcus aureus infections. This highlights an urgent need to reinforce and optimize prevention, control, timely detection and effective treatment strategies for multidrug--resistant Staphylococcus aureus strains.

Abstract Background The emergence of vancomycin-resistant Staphylococcus aureus (VRSA) has become a global concern for public health. The proximity of vancomycin-resistant enterococcus (VRE) and methicillin-resistant S. aureus (MRSA) is considered to be one of the foremost risk factors for the development of VRSA. This study aimed to determine the incidence, risk factors, and clinical outcomes of intestinal co-colonization with VRE and MRSA. Methods A case–control study was conducted in 52-bed intensive care units (ICUs) of a university-affiliated hospital from September 2012 to October 2017. Active surveillance using rectal cultures for VRE were conducted at ICU admission and on a weekly basis. Weekly surveillance cultures for detection of rectal MRSA were also conducted in patients with VRE carriage. Patients with intestinal co-colonization of VRE and MRSA were compared with randomly selected control patients with VRE colonization alone (1:1). Vancomycin minimum inhibitory concentrations (MICs) for MRSA isolates were determined by the Etest. Results Of the 4679 consecutive patients, 195 cases and 924 controls were detected. The median monthly incidence and duration of intestinal co-colonization with VRE and MRSA were 2.3/1000 patient-days and 7 days, respectively. The frequency of both MRSA infections and mortality attributable to MRSA were higher in the case group than in the control group: 56.9% vs. 44.1% (P = 0.011) and 8.2% vs. 1.0% (P = 0.002), respectively. Independent risk factors for intestinal co-colonization were enteral tube feeding (odds ratio [OR], 2.09; 95% confidence interval [CI] 1.32–3.32), metabolic diseases (OR, 1.75; 95% CI 1.05–2.93), male gender (OR, 1.62; 95% CI 1.06–2.50), and Charlson comorbidity index < 3 (OR, 3.61; 95% CI 1.88–6.94). All MRSA isolates from case patients were susceptible to vancomycin (MIC ≤ 2 mg/L). Conclusions Our study indicates that intestinal co-colonization of VRE and MRSA occurs commonly among patients in the ICU with MRSA endemicity, which might be associated with poor clinical outcomes.
