The Effects of Different Treatment Methods on Blood Hematological Parameters İn COVID 19: A Retrospective Look at Patients in Pandemic İntensive Care Unit During The First Wave of the Pandemic

Introduction: In this study, we compared the pre- and post-treatment values of basic hematological parameters in severe COVID 19 patients, whose were received favipiravir, tocilizumab, methylprednisolone and convalescent plasma therapy. Methods: Hematological parameters such as eosinophyl, neutrophil, lymphocyte, platelet count and, neutrophil / lymphocyte, platelet/ lymphocyte ratio were investigated pre and post treatment of favipiravir, tocilizumab convalescent plasma and methylprednisolone in severe COVID 19 patients in ICU. Results: Lymphocyt values were increased after convelescent plasma theraphy and i.v. methyl prednisolon group. Eosinophil count improvement was only in the favipiravir group . We found that favipiravir, convalescent plasma andmethyl prednisolon treatment, were statistically significant increased both NLR and PLR. Conclusion : Hematologic parameters and their contribution of the respond of the treatment and clinical improvement should be taken into account.
