The cytokine storm, a form of systemic inflammatory response syndrome,
is one of the most dreadful complications that can occur
during COVID-19. In this work, we aimed at studying the occurrence
of a cytokine storm in a cohort of COVID-19 patients (Cpts) from Córdoba
(Argentine). During first wave, we collected sera from individuals
with RT-PCR+ for SARS-CoV2 hospitalized in Hospital Privado
with moderate (MOD) and severe (SEV) disease (n=62, aged 21-80
years) as well as healthy controls (HC n=24, age matched), to determine
the concentrations of IL-1b, IL-6, IL-8, IL-10, IL-12, IL-28A/B,
IL-29, TNF, IP-10, IFNa2, IFNb, IFNg and GM-CSF by LEGENDplexTM.
Males represented 74% of MOD and 67% of SEV Cpts. Hypertension
(HT, 48%), obesity (31%), dyslipidemia (DL, 24%), and
diabetes (24%) were the most frequent comorbidities. All cytokines,
except IL-28A/B, were significantly increased in total Cpts in comparison
with HC (p<0.01). Elevated levels of IL-6 and CRP (p<0.01)
between 4-7 day after hospitalization were found in all Cpts who
died, but the cytokine profiles were different in deceased SEV than
in MOD Cpts. Mortality in SEV group was associated with high levels
of IL-6 (p<0.001), GM-CSF (p<0.01), IL-8, CRP, leukocytosis and
decreased platelets (p<0.0001 for all). Comorbidities were linked to
particular patterns of immune mediators on admission but not afterwards
during infection, with HT Cpts exhibiting increased IP-10 levels
but DL Cpts showing lower concentration of IL-1b, GM-CSF and IL-10 compared to no-HT and no-DL Cpts, respectively (p<0.05).
The frequency of Cpts who required O2 support was higher in HT
(84%) vs DL (67%). Although our data have similarities with those
in international reports, the complete profiling of different parameters
(cytokine/chemokines, risk factors, epidemiological and clinical
characteristics) in the local cases add value by identifying particularities
that may be relevant for the management and prognosis during
SARS-CoV2 infection.
