Abstract |
Introduction |
Cytokine storm is one of the consequences of the severe forms of COVID-19 due to excessive immune response. In this study, we investigated the therapeutic effect of plasmapheresis and its role on the inflammatory cytokines levels in patients suffering from severe COVID-19.
Methods |
In plasmapheresis group, 22 severe cases of COVID-19 receiving three cycles of plasmapheresis with time interval of 24–36 h and 22 COVID-19 patients as the control group were enrolled. Clinical history and laboratory parameters as well as IL-1, IL-6, IFN-γ and IL-17 cytokines serum levels in the time points of before and after plasmapheresis were studied.
Results |
In severe COVID-19 patients, plasmapheresis significantly improved clinical and laboratory parameters such as cough, weakness, fever, blood oxygen saturation and CRP levels. Serum levels of IL-1, IL-6, IFN-γ and IL-17 in the group of patients receiving plasmapheresis, had a significant decrease following plasmapheresis courses. Although only IL-6 level in the control group had a significant decrease between the days 1–14 of disease. Also, at both time points of before and after plasmapheresis, serum levels of IL-1, IL-6, IFN-γ and IL-17 were inversely correlated to blood oxygen saturation.
Conclusion |
Based on the obtained results, plasmapheresis therapy in severe forms of COVID-19 can effectively improve the clinical symptoms of the disease and reduce inflammatory markers. Therefore, it is suggested that plasmapheresis can be evaluated in standard treatment protocols for severe forms of COVID-19.
