Procalcitonin levels rise in response to systemic inflammation, especially of
bacterial origin. Multiple randomized controlled trials have demonstrated that
procalcitonin-based algorithms can safely reduce antibiotic use in 2 clinical
scenarios. First, in stable, low-risk patients with respiratory infections,
procalcitonin levels of <0.25 µg/L can guide the decision to withhold antibiotics
or stop therapy early. Second, in critically ill patients with suspected sepsis,
clinicians should not initially withhold antibiotics, but procalcitonin levels of
<0.5 µg/L or levels that decrease by ?80% from peak can guide discontinuation
once patients stabilize. The recent stop antibiotics on procalcitonin guidance
study (SAPS), the largest procalcitonin trial to date, demonstrated reduction in
both antibiotic exposure and mortality in critically ill patients. Although
procalcitonin is ready for routine use, future research should examine optimal
strategies for implementation in hospitals, its real-world impact on clinical
outcomes and costs, its applicability to immunocompromised patients, and the
generalizability of trials to the US population.
