Evaluation of clinical features and laboratory findings in critical intensive care unit patients with severe coronavirus disease-19 who underwent extracorporeal cytokine adsorption.

AIM: To evaluate the inflammatory parameters and oxygenation in severe coronavirus disease-19 patients who underwent extracorporeal cytokine adsorption (CA).

METHODS: Patients who underwent extracorporeal CA for cytokine storm were included in the study. The changes in oxygenation, laboratory parameters, and mortality rates were investigated.

RESULTS: Thirty-six patients were included in the study. The hemoglobin, thrombocyte, and C-reactive protein (CRP) decreased, and PaO2 /FiO2 ratio increased (p < 0.001; p < 0.01; p < 0.001; p = 0.04, respectively). Twelve (33.3%) patients received a single session, 24 (66.6%) received 2 or more sessions. CRP and fibrinogen levels decreased, and PaO2 /FIO2 ratio increased in the single session group (p = 0.04; p = 0.04; p = 0.01, respectively). In the multi-session group, the hemoglobin, platelet, procalcitonin, and CRP levels decreased, and PaO2 /FIO2 ratio increased (p < 0.01; p = 0.02; p = 0.02; p < 0.01; p = 0.01, respectively). Day 15, 30, and 90 mortality rates were 61.1%, 83.3%, and 88.9%.

CONCLUSION: CA with hemoperfusion reduced CRP and improved oxygenation; however, mortality rates were high.
