Investigation: the journal article itself states : "seizures as a complication of the autologous peripheral blood stem cells (pbsc) are rare" and complications during infusion of thawedautologous stem cells are mostly related to side effects of dimethyl sulfoxide (dmso), and volume infused at the time of infusion.The etiology of seizures in these patients is poorly understood."per the article, with the intent of evaluating a causative factor for the seizures, patients underwent imaging studies, electroencephalogram, cerebrospinal fluid analysis, electrolyte analysis,arterial blood gas analysis, and evaluation of medication history; no causative factors were found.The handbook for therapeutic apheresis states the overall incidence of transfusion reactions has a frequency of 1.6%.Furthermore, severity is greater in acutely ill patients.The customer was unable to provide a lot number for the collection set or a serial number for the machine used, therefore a device history record review could not be performed for the collection set lot.All lots must meet acceptance criteria for release.A checkout of the machine could also not be performed.Root cause: root cause of the patient reaction remains undetermined at this time.Possible causes include but are not limited to:- sensitivity to dmso- patient physiology.
