Correlation between procalcitonin and efficacy of antibiotic therapy

In this paper we have examined the case of a patient admitted to the ICU for about four months with initial diagnosis of severe respiratory failure, which in the course of hospital stay was subject to multiple outbreaks. We dosed daily procalcitonin, whose values have always correlated with the patient’s infectious status allowing, together with clinical and microbiological data, prompt antibiotic treatment and a highlight of the phenomenon of antibiotic resistance.
