Multicenter Study Observational StudyPrognostic value of pro-adrenomedullin, procalcitonin and C-reactive protein in predicting outcome of febrile urinary tract infection.
Bacterial infections such as febrile urinary tract infection (fUTI) may run a complicated course that is difficult to foretell on clinical evaluation only. Because the conventional biomarkers erythrocyte sedimentation rate (ESR), leucocyte count, C-reactive protein (CRP) and procalcitonin (PCT) have a limited role in the prediction of a complicated course of disease, a new biomarker-plasma midregional pro-adrenomedullin (MR-proADM)-was evaluated in patients with f UTI. We conducted a prospective multicentre cohort study including consecutive patients with f UTI at 35 primary-care centres and eight emergency departments. ⋯ Median MR-proADM level was 1.42 (interquartile range 0.67-1.57) nM; significantly elevated MR-proADM levels were measured in patients with bacteraemia, those admitted to the intensive care unit, and in 30-day and 90-day non-survivors, compared with patients without these characteristics. The diagnostic accuracy for predicting 30-day mortality in fUTI, reflected by the area-under-the-curve of receiver operating characteristics were: MR-proADM 0.83 (95% CI 0.71-0.94), PCT 0.71 (95% CI 0.56-0.85); whereas CRP, ESR and leucocyte count lacked diagnostic value in this respect. This study shows that MR-proADM assessed on first contact predicts a complicated course of disease and 30-day mortality in patients with fUTI and in this respect has a higher discriminating accuracy than the currently available biomarkers ESR, CRP, PCT and leucocyte count.

Multicenter Study Observational StudyPan-European early switch/early discharge opportunities exist for hospitalized patients with methicillin-resistant Staphylococcus aureus complicated skin and soft tissue infections.
The objective of this study was to document pan-European real-world treatment patterns and healthcare resource use and estimate opportunities for early switch (ES) from intravenous (IV) to oral antibiotics and early discharge (ED) in hospitalized patients with methicillin-resistant Staphylococcus aureus (MRSA) complicated skin and soft tissue infections (cSSTIs). This retrospective observational medical chart review study enrolled 342 physicians across 12 European countries who collected data from 1542 patients with documented MRSA cSSTI who were hospitalized (July 2010 to June 2011) and discharged alive (by July 2011). Data included clinical characteristics and outcomes, hospital length of stay (LOS), MRSA-targeted IV and oral antibiotic use, and ES and ED eligibility according to literature-based and expert-validated criteria. ⋯ IV treatment duration (9.3 ± 6.5 vs. 14.6 ± 9.9 days; p <0.001) and hospital LOS (19.1 ± 12.9 vs. 21.0 ± 18.2 days; p 0.162) tended to be shorter for patients switched from IV to oral treatment than for patients who received IV treatment only. Of the patients, 33.6% met ES criteria and could have discontinued IV treatment 6.0 ± 5.5 days earlier, and 37.9% met ED criteria and could have been discharged 6.2 ± 8.2 days earlier. More than one-third of European patients hospitalized for MRSA cSSTI could be eligible for ES and ED, resulting in substantial reductions in IV days and bed-days, with potential savings of €2000 per ED-eligible patient.

Statins use and risk of mortality in patient with Clostridium difficile infection.
Current evidence suggests that statins may improve outcome in infectious diseases. This study aims to assess whether statins use is associated with reduced risk of 30-day mortality in Clostridium difficile infection (CDI). Using the computerized database of Clalit, the largest healthcare provider in Israel, we identified a cohort of adult subjects (age ≥40 years) who tested positive on a C. difficile toxin assay performed between January 2011 and December 2012. ⋯ The risk of 30-day mortality decreased with increasing number of filled statins prescriptions; adjusted OR = 0.77 (95% CI 0.67-0.89) for each additional prescription. Current aspirin use was also independently associated with reduced mortality; adjusted OR = 0.64 (95% CI 0.43-0.88). In conclusion, current statins use, particularly long-term use, has a dose-response protective effect on mortality in patients with CDI.
