Evaluation of serum procalcitonin level as a biomarker for disease severity in Covid-19 patients: The experience of Mohammed VI University Hospital in Oujda.

Abstract

The pandemic of coronavirus disease (Covid-19) has infected millions of individuals around the globe. The current study was aimed to evaluate the serum procalcitonin (PCT) level as a biomarker for bacterial co-infection and disease severity in Covid-19 patients. A total of 319 Covid-19 positive patients were examined in this study. Among the total individuals, 169 (53%) were male while 150 (47%) were female. Among the examined samples, 142 (44.5%) were hospitalized in Covid services, and 177(55.5%) were admitted in the intensive care unit (ICU). The mean PCT level for Covid-19 services patients was 0.58 ng/mL and for ICU patients was 7.84 ng/mL. The statistical analysis revealed that there was a significant association of PCT value and age (P<0,0001) while there was no association of gender and PCT value in COVID-19 patients (P=0.2745). Most Covid-19 patients have low PCT levels but elevated markers of inflammation such as C-reactive protein (CRP) on admission. It can be concluded that the serial PCT measurement could determine the prognosis of disease and presence of bacterial co-infection in Covid-19 patients. The main objective of our study is to determine the role of serum procalcitonin in the diagnosis and clinical management of patients with COVID-19 from Oriental Region of Morocco, also we evaluate the correlation between Procalcitonin and disease severity in COVID-19. We report the experience of the Moroccan Mohammed VI University Hospital of Oujda.
