Brief Summary:
Bloodstream infections (BSI) are a major cause of morbidity and mortality. Community-onset BSI have an overall attributable mortality of 10-13% while nosocomial BSI mortality ranges are quite variable from 12-80%. Bloodstream infections are also costly and result in prolonged hospital stays. Nosocomial BSIs have been shown to increase length of stay by 5-25 days and increase costs $23,000 - 40,000 above matched controls. The duration of therapy necessary to clear blood stream infections is unknown and no study has systematically addressed this issue. The use of antimicrobials is also not without consequence. These include financial cost, side-effects, promotion of superinfection (especially Clostridium difficile-associated diarrhea), and the promotion of microbial resistance. We hypothesize that a procalcitonin (host biomarker) and endotoxin (microorganism biomarker)-guided treatment plan could significantly decrease unnecessary exposure to antibiotics in patients with bloodstream infections.

Study Type : Observational
Actual Enrollment : 223 participants
Observational Model: Cohort
Time Perspective: Prospective
Official Title: Procalcitonin and Endotoxin Sequential Levels to Optimize the Treatment of Bloodstream Infections
Study Start Date : June 2009
Actual Primary Completion Date : June 2016
Actual Study Completion Date : June 2016

Primary Outcome Measures :
  1. To determine the optimal length of treatment by observing the normalization of procalcitonin (PCT) and Endotoxin levels, compared with the length of treatment by standard of care. [ Time Frame: 30 days ]

Secondary Outcome Measures :
  1. To determine if procalcitonin and endotoxin levels (or lack of decrease) are associated with treatment failure, complication, survival, cost, length of stay, progression to severe sepsis, or superinfections. [ Time Frame: 30 days ]

Biospecimen Retention:   Samples Without DNA
Blood (maximum 40mL) will be collected for future use or for purposes that are not integral to the current research.
