Abstract :Aim: Therapeutic plasma exchange (TPE) is a frequently discussed treatment modality in severe coronavirus disease 2019 (COVID-19) patients. It requires an apheresis device and experienced personnel for the application. In this study, we aimed to reveal the characteristics and clinical outcomes of adult patients with COVID-19 who experienced TPE. Material and Methods: Adult patients who had undergone TPE in our apheresis unit were retrospectively analyzed and COVID-19-positive cases were included in the study. All the medical information about the cases was obtained from the electronic database and technical details of the procedures were gathered from apheresis unit records. Results: A total of 80 patients with a median age of 60 (19-85) years were included in the study. Severe pneumonia was present in 98.8% (n=79) of the cases. More than three-quarters of the patients had lymphopenia, critically elevated C-reactive protein (CRP), and D-dimer, and 41.0% (n=32) had high ferritin. The median length of stay in the intensive care unit was 26 (5-124) days. The mortality rate observed on the 14th and 28th days following the TPE procedure was 51.3% (n=41) and 75.0% (n=60), respectively. High ferritin level, multiple organ failure (MOF), and intubation were parameters found to be associated with mortality in the multivariate analysis. Conclusion: The mortality rate observed in patients with COVID-19 who underwent TPE in our study was similar to the cases in the literature without the procedure, while it has been shown that high ferritin levels, intubation, and the presence of MOF increase the risk of mortality.Keywords : terapötik plazma değişimi, pnömoni, COVID-19
