Efficacy and safety of plasma exchange: ann 11-year single-center experience of 2730 procedures in 317 patients.

We reviewed retrospectively 317 patients who received 2730 plasma exchange (PE) procedures. According to guidelines published by the American Society for Apheresis (ASFA) in 2013, there were 220 (69%), 55 (17%), 32 (9%), and 7 (4%) patients who were treated with PE for a disease or condition considered as category I, II, III, and IV, respectively. Overall, 73%, 72%, and 69% of the patients showed an improvement of the underlying disease or condition at the end of the PE, and at 3 months and at 6 months after finishing the PE, respectively.
