ABSTRACT
The goal of this study was to assess plasma procalcitonin (PCT) concentrations during infectious events of burns in the ICU. We conducted a prospective, observational study in a 20-bed Burn Intensive Care Unit in Tunisia. A total of 120 septic patients admitted to the Burn ICU were included in our study. Sepsis was assumed according to the French Burn Association criteria for the presence of infection. Serum PCT was measured over the entire septic episode every 48 hours until resolution of infection, based on clinical signs and decrease of PCT of about 80% compared to its initial value. Patients were assigned to two groups depending on clinical course and outcome:
Group A = patients with favourable evolution; Group B = patients with unfavourable evolution. Monitoring of kinetics of PCT allowed us to judge the effectiveness of the initial antibiotic therapy, with a threshold of 43.5% decrease at day 3 of treatment, with a better sensitivity and specificity of 79.6% and 87.7% respectively. In addition, PCT monitoring allowed a reduction in the duration of antibiotic therapy of 5±2.8 days versus 8 to 10 days before the use of PCT.
