Popis: Background: Hypotensive reactions to platelet transfusions performed with white cell (WBC)-reduction filters with negatively charged surfaces have been reported recently in patients taking angiotensin-converting enzyme (ACE) inhibitors. Experimental studies have shown that the filter material can activate bradykinin, which may cause symptoms in patients with reduced bradykinin catabolism. Symptomatic adverse reactions after the administration of fresh-frozen plasma (FFP) through a WBC-reduction filter have not been reported in a patient on ACE Inhibitor medication. Case Report: A 58-year-old man with congenital coagulation factor V deficiency and hypertension treated with an ACE inhibitor was admitted for rehabilitation after orthopedic surgery. On 3 consecutive days, he received FFP through a WBC-reduction filter; within minutes of the beginning of each infusion, he experienced a drop in blood pressure, facial erythema, abdominal pain, and anxiety. When the infusions were stopped, symptoms quickly abated without treatment. Multiple prior transfusions of unfiltered FFP and FFP filtered through a WBC-reduction filter made by a different manufacturer, as well as subsequent transfusions of unfiltered FFP, had not produced such reactions. Conclusion: Facial flushing, hypotension, and abdominal pain after FFP administration in a patient on ACE inhibitor medication appeared to be associated with a specific type of WBC-reduction filter. This association and other reported studies suggest that special caution is warranted when patients who are treated with ACE inhibitors receive blood components administered through WBC-reduction filters capable of generating bradykinin.
