Is procalcitonin a reliable indicator of sepsis in spinal cord injury patients: an observational cohort study

Abstract

Study design: Prospective observational cohort study.

Objective: To understand if serum procalcitonin (PCT) is a reliable indicator of sepsis in spinal cord injury (SCI) patients for better prognosis and earlier diagnosis when compared with other common biomarkers such as C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), white blood cells (WBC), blood culture and body temperature.

Methods: From March 2021 to August 2022, data were collected for SCI patients who developed septicaemia. In addition to neurology and admission, the following blood samples were collected on day one of infection: PCT, CRP and WBC. Linear regression analysis was performed to determine the relationship between PCT, CRP and WBC.

Results: A total of 27 SCI patients had an infection during their stay in the regional centre; however, only 10 developed septicaemias. 100% of SCI individuals with sepsis had elevated PCT levels, whilst 60% had elevated CRP and 30% had elevated WBC levels. There was a strong positive correlation between PCT and CRP (R2 = 0.673, CI = 95%, 5.5-22.8, p < 0.05) and a weaker positive correlation between PCT and WBC (R2 = 0.110, CI = 95%, 4.2-10.9, p < 0.05).

Conclusion: In SCI individuals, there was a correlation between serum PCT levels and septicaemia. Alongside this, PCT appeared to be more consistent throughout the study population when compared with CRP and WBC. However, this was a preliminary study and further research is required on a larger scale.
