Dietrich and colleagues [1] are to be commended for contributing to our knowledge of the anaphylactic risk associated with aprotinin in 12,403 patients. The conclusions are consistent with immunologic concepts governing antibody-mediated reactions to large proteins, and are also consistent with previous publications on the same subject. It is frequently pointed out that many other drugs more commonly used during anesthesia also carry a risk of anaphylaxis. At a frequency of 1% to 2%, these reactions greatly exceed those to aprotinin. The data from this series does provide some support for the authors contention that reactions to aprotinin may be less frequent but are much more serious.
The importance of weighing risks against benefits in patients exposed to aprotinin within the previous 6 months is very clear and difficult to overemphasize. As the authors mention, discussion of anaphylaxis at the September 2006 Food and Drug Administration panel on aprotinin produced rewording of the labeling and induced the sponsor to back away from efforts to market the drug for procedures in which salvage with immediate cardiopulmonary bypass is not available, such as joint replacement. It is important to note that the authors have not encountered a severe reaction since 1998, suggesting that awareness of the problem can generate safe practice. It is also worth noting that absence of proof is not proof of absence, and the possibility of undetected prior exposures must be kept in mind.
