China: A recent study in the journal Burns showed that procalcitonin (PCT) kinetics early after burn could be a prognostic factor for mortality and sepsis among major burn patients. This implies that serum PCT levels in major burn patients could be a diagnostic biomarker for sepsis.
Severe bacterial infection remains the leading cause of death despite the great advances in the field of burn care. Sepsis is the most common severe complication occurring in major burn patients and is a cause for very high mortality. Early diagnosis followed by adequate antimicrobial therapy is critical for improving the diagnosis of sepsis patients.
Against the above background, Jianglin Tan, State Key Laboratory of Trauma, Burn and Combined Injury, Chongqing, PR China, and colleagues aimed to investigate the clinical significance of PCT kinetics early afterburn and the perioperative period in a retrospective study. Also, they assessed the diagnostic performance for sepsis in major burn patients.
The study included major burn patients (≥40% total body surface area who were admitted to Southwest Hospital, Chongqing, China from 2014 to 2019. A total of 321 patients were included. PCT kinetics was analyzed during the 1st-week afterburn, the perioperative period, and at the onset of clinical suspected sepsis.
The study revealed the following findings:
- Serum PCT concentration rose immediately after burn injury.
- Factors associated with increased PCT level in the 1st week after burn include greater burn area (>70% TBSA) and lower age (≤14 years).
- Correlations between PCT kinetics after burn and the risk of early development of sepsis and mortality were observed.
- At the onset of sepsis, serum PCT increased significantly compared to its basal level in the 48 h before diagnosis.
- The area under the receiver operating characteristics curve of PCT concentration and its kinetic changes was 0.788 and 0.826, respectively.
- PCT kinetics showed better accuracy than PCT concentration in discrimination of Gram-positive sepsis.
- The optimal diagnostic thresholds for PCT concentration and its kinetics were 1.41 ng/mL, and a 1.34-fold elevation compared to the baseline level.
"PCT kinetics in the early stage after burn was a prognostic factor for sepsis and mortality among major burn patients," wrote the authors. "Serum PCT levels could be a diagnostic biomarker for sepsis patients with major burns."
