Review Case Reports
Acute hypotensive transfusion reaction with concomitant use of angiotensin-converting enzyme inhibitors: a case report and review of the literature.
Hypotension can be a manifestation of transfusion reactions, including acute hemolysis, bacterial contamination, transfusion-related acute lung injury, and anaphylaxis. In addition to hypotension, these reactions usually present with other characteristic symptoms and signs. In rare cases, hypotension is the only manifestation of a transfusion reaction. ⋯ We report a case of AHTR observed in a patient on angiotensin-converting enzyme inhibitor therapy. The Naranjo adverse drug reaction probability scale score indicated that the association between angiotensin-converting enzyme inhibitor therapy and AHTR was probable. If a patient on angiotensin-converting enzyme inhibitor therapy develops AHTR, it is important to recognize the need to switch to another class of antihypertensive medication, at least while the patient continues to require transfusion.
