Abstract
To evaluate in SARS-CoV-2 patients the behavior of presepsin .
To compare the informations provided with those of other inflammatory biomarkers.
To provide new biochemical informations in patients suffering from SARS-CoV-2.
Background
A severe form of pneumonia, is the leading complication of the respiratory Coronavirus disease 2019 (COVID-19), recently renamed SARS-CoV-2. Soluble cluster of differentiation (CD)14 subtype (sCD14-ST also termed presepsin PSP) is a regulatory factor that modulates immune responses by interacting with T and B cells, useful for early diagnosis, prognosis and risk stratification prediction.
Methods
In 75 consecutive patients suffering from COVID-19 microbiology proven infection, admitted to intensive care unit (ICU, n = 21, 28%) and/or in infectious disease ward (IW, n = 54, 72%), PSP (Pathfast, Mitsubishi, Japan) has been measured in addition to routine laboratory tests performed during the period of hospitalization (from January to March 2020).
Results
PSP demonstrates: -statistically significant higher values (Mann-Whitney test) in 6 patients died (median, IQR = 1046, 763–1240; vs 417, 281–678 ng/L, p < 0.05); -statistically significant but poor correlations with CRP (r = 0.59, p < 0.001), LDH (r = 0.52, p < 0.001) and PCT (r = 0.72, p < 0.001) measured at the same day; -a significant relationship between concentrations and ICU stay. In fact patients showing PSP values higher than 250 ng/L (cut-off for risk stratification) did stay in ICU for a significantly longer time (median 17 days, IQR 12–31; p < 0.001) than those exhibiting lower values (median 10 days, IQR 7–18).
Conclusions
The data obtained seems to demonstrate the role of PSP in providing prognostic information in COVID-19 patients, allowing to identify, during the early phase of the monitoring, the patients suffering from a more severe disease which will be hospitalized for a more long time.
