We investigated the prognostic role of high MICs for antistaphylococcal agents in patients with methicillin-sensitive Staphylococcus aureus catheter-related bloodstream infection (MSSA CRBSI). We prospectively reviewed 83 episodes from 5 centers in Spain during April 2011-June 2014 that had optimized clinical management and analyzed the relationship between E-test MICs for vancomycin, daptomycin, oxacillin, and linezolid and development of complicated bacteremia by using multivariate analysis. Complicated MSSA CRBSI occurred in 26 (31.3%) patients; MICs for vancomycin and daptomycin were higher in these patients (optimal cutoff values for predictive accuracy = 1.5 μg/mL and 0.5 μg/mL). High MICs for vancomycin (hazard ratio 2.4, 95% CI 1.2-5.5) and daptomycin (hazard ratio 2.4, 95% CI 1.1-5.9) were independent risk factors for development of complicated MSSA CRBSI. Our data suggest that patients with MSSA CRBSI caused by strains that have high MICs for vancomycin or daptomycin are at increased risk for complications. [ABSTRACT FROM AUTHOR]

Introduction: Imported diseases by travellers and immigrants are a priority in the prevention of emerging infectious diseases in the 21st century. There are international records on imported diseases, but no such records are available in Spain., Material and Methods: The cooperative network +Redivi was created in 2009 and consists of 11 national healthcare centres. +Redivi collects demographic data relating to travel/migration and infectious diseases in brief, computerised forms., Results: From January 2009 to October 2011, we collected 4,570 patients and recorded the main demographic data (age, sex, presence of immunosuppression), travel data (destination, duration, time between the return trip and the consultation) and data regarding the migratory process (country of origin, time between the arrival in Spain and the first consultation), as well as preventive measures that have been taken (pre-travel advice, need for malaria chemoprophylaxis, drug that was used and whether it was correct), the reason for coming to the consultation, and final diagnoses of the travellers, immigrants and immigrants-travellers. Likewise, the most frequent diagnoses of asymptomatic patients who came for a check-up are described for each of the three groups., Conclusions: The +Redivi network allows us to identify and quantify the geographical origin and the type of patients affected, as well as time pattern of infections imported by migrants and travellers. Preliminary data show the significant presence of transmissible diseases and the potential reintroduction in Spain, as well as the importance of systematic screening in patients that came from tropical areas. The objective of +Redivi is to evaluate the impact of imported diseases in Spain in order to contribute to improving the care of patients, to have an influence on prevention and treatment of the most prevalent imported diseases, and to detect possible outbreaks., (Copyright © 2011 Elsevier España, S.L.
