• Note (General): type:Thesis; Plasma exchange (PEX) using fresh frozen plasma has considerably reduced the mortality rate in patients with immune-mediated thrombotic thrombocytopenic purpura (iTTP). However, some patients still do not survive even with treatment, but little information is available regarding which treatment these patients received. This study was conducted to obtain this information in 240 patients who met the current iTTP diagnostic criteria and completed at least 30 days of follow-up except for deceased cases. These patients were divided into three groups: survivors (n = 195), TTP-related deaths (n = 32), and other cause of death (n = 13). In the TTP-related death group, 26 of 32 patients experienced sudden death, mostly following radical hypotension and bradycardia. The median follow-up time after admission was 5.0 days, and the median number of PEX sessions was 2.5. Nine patients underwent autopsy and had cardiac microvascular thrombi in arterioles. Levels of lactate dehydrogenase, total bilirubin, serum creatinine, and D-dimer were significantly higher in the TTP-related death group than in the survivors group. Frequent PEX (> 20 sessions) was not associated with TTP-related death. In the acute phase of iTTP, patients with substantial organ damage caused by microthrombi have a greater mortality risk, even after just a few PEX sessions.; 博士（医学）・乙第1518号・令和3年12月21日; © Japanese Society of Hematology 2021.; The version of record of this article, first published in International journal of hematology, is available online at Publisher’s website: http://dx.doi.org/10.1007/s12185-021-03197-5.; 発行元が定める登録猶予期間終了の後、本文を登録予定（2022.10）; identifier:International journal of hematology Vol.114 No.4 p.415-423 (2021 Oct); identifier:09255710; identifier:http://ginmu.naramed-u.ac.jp/dspace/handle/10564/3963; identifier:International journal of hematology, 114(4): 415-423
