RESUMEN
BACKGROUND: Therapeutic apheresis (TA) as primary or adjunctive therapy proved itself in a broad spectrum of diseases. This study aims to present TA practices in a tertiary center with an emphasis on the rate of the utility of TA on the new American Society for Apheresis (ASFA) indications. METHODS: We conducted a retrospective analysis of data regarding TA applications through our electronic medical database from June 2016 to July 2018. The data included demographics, clinical indications, and procedural characteristics. We also searched for the rate of the utility of TA procedures on new ASFA indications by entering both the diagnostic and TA modality codes for these indications on the electronic database during the study interval. RESULTS: A total of 720 TA procedures were performed on 96 patients (54 males, 42 females, with a mean age of 48.15 ± 26.71 years). The procedures were 68.8 % therapeutic plasma exchange (TPE), 16.4 % leukocytapheresis, 11.5 % immunoadsorption (IA), 3.1 % double filtration plasmapheresis (DFPP), and 0.13 % erythrocyte exchange. The categorical indications included 60.41 % category I and category II, 28.12 % category III, and 1.04 % category IV. The most common indication was thrombotic thrombocytopenic purpura (TTP) (26.04 %). The procedure failure rate was 2.08 %. Patient-related adverse events were reported in 7.5 % of procedures. The case mortality rate was 16.66 %. TA utility rate was 0.98 % for the new indications in the ASFA 2016 guideline. CONCLUSION: Therapeutic apheresis is a progressively developing, safe, and effective treatment modality with add-on indications. Physicians should keep track of new developments on this modality to implement the appropriate indications into clinical practice. HIPPOKRATIA 2018, 22(4): 167-172.
