Multicenter Study
The time course of blood C-reactive protein concentrations in relation to the response to initial antimicrobial therapy in patients with sepsis.
C-reactive protein (CRP) may be a useful marker of sepsis but its use in the evaluation of response to therapy remains poorly defined. The aim of this study was to define the time course of CRP levels in septic patients according to their response to initial antimicrobial treatment, and to search for possible correlations between CRP levels and other clinical and biological variables. ⋯ Changes in CRP levels over the first 48 h of therapy can help to evaluate the response to initial antimicrobial therapy in septic patients.

Intensive care units (ICUs) are unfortunately the epicenters of nosocomial infections. The aim of the study was to investigate device associated infection rates in a small Turkish hospital. Device utilization ratios and device associated infection rates were calculated according to definitions of the Centers for Disease Control (CDC). ⋯ In our study ventilator associated pneumonia was the most frequent nosocomial infection with a rate of 59.7 per 1,000 ventilator days. The most frequent pathogen of device associated infection was Candida spp. High rates of device associated infections in a small Turkish hospital clearly indicate the urgent need of the implementation of infection control guidelines.

Multicenter Study Clinical Trial
Influence of steroids on procalcitonin and C-reactive protein in patients with COPD and community-acquired pneumonia.
The induction of C-reactive Protein (CRP) may be attenuated by corticosteroids, whereas Procalcitonin (PCT) appears to be unaltered. We investigated, whether in community-acquired pneumonia (CAP) a combined antibiotic-corticosteroid therapy may actually lead to different slopes of decline of these inflammatory markers. ⋯ In patients with COPD and CAP, the time courses over 7 days of PCT and CRP showed a nearly parallel decline compared to non-COPD patients with CAP. Contrary to the induction phase, corticosteroids do not modify the time-dependent decay of PCT and CRP when the underlying infectious disease (CAP) is adequately treated.

Bloodstream infections (BSI) with gram-negative bacteria (GNB) are one of the most serious infections in the hospital setting, a situation compounded by the increasing antibiotic resistance of gram-negative bacteria causing BSI. The aim of the study was to assess the impact of antibiotic multiresistance of GNB in BSI on mortality rates and length of stay (LOS). ⋯ Multiresistance of GNB causing BSI was associated with higher mortality rates and longer LOS in ICU. The initial antibiotic therapy was significantly more often inadequate and might have had an impact on overall mortality. Thus, an effective strategy to administer an appropriate initial empirical antibiotic therapy, especially in patients with risk factors, must be sought. Moreover, the overall usage of antimicrobials must be limited and infection control guidelines should be followed to reduce the emergence and transmission of multiresistant GNB.
