Abstract
Purpose: In this study, we aimed to evaluate the laboratory markers used
in the diagnosis of COVID-19 and to present the parameters that can be
used to predict mortality. Material and method: The cases followed in
the intensive care unit due to COVID-19 in our clinic between March 2020
and December 2020 were evaluated retrospectively. A total of 374
patients who met the study criteria were included in the study. The
patients were divided into two groups as the patients who were
discharged from the intensive care unit with no mortality and patients
with a mortal course. Patients with no mortality constituted Group-1,
and patients with a mortal course constituted Group-2. Demographic,
clinical, and laboratory characteristics of the patients were compared.
Results: The number of patients in group-1 consisting of patients with
no mortality was 148 (39.5%), and the number of patients in group-2
consisting of patients with mortality was 226 (60.4%). In the group of
patients without mortality, 84 (56.8%) of the patients were male, while
in the mortality group, 127 (56.2%) were male. In the mortality group,
procalcitonin, CRP, BUN, D-dimer, troponin, LDH, lactate, and INR values
were higher, albumin value was lower, and this difference was
statistically significant (p<0.001). In the logistic
regression analysis, PLT and D-dimer were found as the independent
variables of mortality. Conclusion: We think that the high procalcitonin
and D-dimer values obtained with routinely examined rapid and easily
accessible blood tests of Covid-19 patients may contribute to mortality
prediction.
