BACKGROUND: Coronavirus disease 2019 (COVID-19) is often complicated by cytokine storm syndrome. Although many interleukins (IL) have predictive value, the sensitivity and specificity of a single marker is limited.
AIM: The purpose of the study is to develop an objective and informative cytokine storm scale for assessing the risk of developing a critical course in patients with COVID-19 associated pneumonia.
MATERIALS AND METHODS: A total of 226 cases of COVID-19 were investigated, 36 (16 %) of which were with poor outcomes. The cytokines IL-1b, IL-2, IL-6, IL-8, IL-10, IL-18, TNF-, IFN, IFN- were studied by enzyme immunoassay, commercial kits manufactured by Vector-Best, RF.
RESULTS: Since IL-6, IL-10, IL-18, and procalcitonin were associated with disease severity and death, these indicators were integrated into a 12-point scale called the cytokine storm scale. The patients who scored more than 6 points had a high risk of a poor outcome of the disease. According to ROC analysis, the area under the curve for the cytokine storm scale was larger than for each of the four markers separately [AUC 0.90 (95% CI 0.84550.9592), p 0.001].
CONCLUSIONS: Thus, the cytokine storm scale system presents superior performance in determining patients with favorable and fatal outcomes to each individual cytokine.
