Procalcitonin Levels in Patients With Fever and a Central Line

Sponsor: Phoenix Children's Hospital

Summary

Procalcitonin (PCT) is one of many inflammatory markers which rises in response to infection. Many studies have shown this marker to be more indicative of a patient's clinical course in comparison to other inflammatory markers, such as Erythrocyte Sedimentation Rate (ESR) and C reactive protein (CRP), when assessing a patient's risk for serious infection. A particular population with potential for serious infection is that of the patient with fever and a central line, most often secondary to an oncologic disease. These patients are often neutropenic and unable to fight off infection, thereby rendering them extremely vulnerable to rapid declines in clinical status. By identifying a level of procalcitonin which is significant as a threshold for serious bacterial infection, the investigators can very early on identify the sickest patients and those who could potentially have a worse clinical course and/or outcome. The primary study goal is to identify whether a level of procalcitonin exists above which rates of bacteremia or serious bacterial infections in patients with fever and a central line exist. The investigators will try to determine if levels of PCT correlate with bacterial infection in line sepsis in the specific population of patients who most often have a central line secondary to an oncologic process. The investigators proposed this theory since peak values of PCT have been shown to be elevated in acute settings making it a useful tool in this particular population.
