ISBT Regional Congress Amsterdam Every year TRIP receives several reports like this one. The category of anaphylactic reaction, defined as allergic reactions with systemic features such as airway obstruction, fall in blood pressure, vomiting or diarrhoea, accounts for the largest number of serious transfusion reactions. In most cases no cause is found for these reactions.

Distributed blood components ISBT Regional Congress Amsterdam TRIP data show that anaphylactic reactions occur relatively frequently during or after transfusion of plasma or platelet concentrates. Most platelet units are also rich in plasma. Data from blood services show that approximately 10% or more of plasma donors use medication which is permitted under donation guidelines.

ISBT Regional Congress Amsterdam Thawed FFP  rejected for transfusion  sample 5 ml This exploratory study investigated the presence of drugs or drug metabolites in donor plasma after quarantine, storage and thawing. Only samples for which the blood supply organisation confirmed that the donor had consented to research use were included.

ISBT Regional Congress Amsterdam I-Tox screening The samples were analysed for approximately 800 drugs or drug metabolites

ISBT Regional Congress Amsterdam 87 samples have been processed All detectable substances that were recognised as drug or drugmetabolite were considered a positive screening result

The most prescribed drugs in The Netherlands in 2009/2010 Metoprolol Omeprazol (also OTC) Acetylsalicylic acid (also OTC) We expected that frequently prescribed drugs or over the counter drugs were most likely to be found in some of the donor plasma units ISBT Regional Congress Amsterdam

ISBT Regional Congress Amsterdam Conclusions It is possible to detect medication in donor plasma after freezing, quarantine, storage and thawing It cannot be excluded that medication taken by the donor in plasma for transfusion could cause an anaphylactic reaction in the recipient
