Can procalcitonin guide decisions about antibiotic management?

[摘要] Yes, but with caution. Multiple randomized controlled trials showed that procalcitonin testing can help guide antibiotic management in a variety of clinical scenarios including sepsis, respiratory tract infection, and exacerbation of chronic obstructive pulmonary disease (COPD), and that procalcitonin guidance led to less antibiotic use with either unchanged or better outcomes. Moreover, observational studies have shown high negative predictive values for procalcitonin testing in other clinical situations such as bacteremia and bacterial meningitis, allowing clinicians to rule out these diagnoses if the clinical probability is low or moderate.
