Procalcitonin: a diagnostic and prognostic biomarker of sepsis in burned patients.
The goal of this study was to analyse plasma procalcitonin (PCT) concentrations during infectious events of burns in ICU. We conducted a prospective, observational study in a 20-bed Burn Intensive Care Unit in Tunisia. A total of 121 patients admitted to the Burn ICU were included in our study. ⋯ Patients were assigned to two groups depending on the clinical course and outcome: Group A = non septic patients; Group B = septic patients. A PCT cutoff value of 0,69 ng/ml for sepsis prediction was associated with the optimal combination of sensitivity (89%), specificity (85%), positive predictive value (82%) and negative predictive value (88%). Serum procalcitonin levels can be used as an early indicator of septic complication in patients with severe burn injuries as well as in monitoring the response to antimicrobial therapy.

Progress in burns research: a review of advances in burn pathophysiology.
Severe burns trigger a wide range of responses in the victim. Initial vascular changes are followed by hypermetabolic, inflammatory and immunologic changes. The prolonged hypermetabolic response is associated with an elevated resting rate of energy consumption, tissue wasting and altered substrate kinetics. ⋯ Some clinical areas in which treatment centred on correcting altered physiology were also included. We have highlighted both the challenges and significant findings. Finally, this paper draws attention to the gaps between progress in basic research and clinical application and suggests areas where further research and funding could be focused.
