It was hypothesized that RCE would be less iron loading compared to simple transfusion. The purpose of this study is to document observations of the potential risks and benefits of RCE in TDT patients.<\/jats:p><\/jats:sec>Study design and methods<\/jats:title>TDT patients treated with RCE were identified and consented for enrolment according to local research ethics standards. Seven patients were enrolled in the study. Charts were retrospectively reviewed from the time of initiation of RCE to the time of the most recent RCE or clinic follow\u2010up. Outcomes were documented and analyzed by descriptive analysis.<\/jats:p><\/jats:sec>Results<\/jats:title>The average age was 30\u2009years. 85.7% were male. 100% were on oral chelation therapy and had hyperferritinemia at baseline. Outcomes included hepatic iron overload (5 of 7), cardiac dysfunction (3 of 7), worsening splenomegaly or extramedullary hematopoiesis (5 of 7), syncopal events during RCE (2 of 7), and new antibodies (1 of 7). Iron overload improved after escalated oral chelation, not in relation to RCE initiation.<\/jats:p><\/jats:sec>Discussion<\/jats:title>We hypothesize complications were higher than expected due to inadequate hematocrit increment and lack of suppression of ineffective erythropoiesis. With no observed benefit in iron status, and high complication rates, we did not find evidence to recommend RCE in patients with TDT.
