Exercise-induced anaphylaxis: improvement after removal of amalgam in dental caries.

ABSTRACT

We present a case of exercise-induced anaphylaxis with improvement following the removal of dental amalgam. Although her symptoms were unresponsive to various kinds of therapy until removal of the amalgam, her symptoms related to exercise improved remarkably after the removal. The increase in plasma histamine levels for exercise provocation test also improved. This suggests that sensitivity to metals might cause exercise-induced asthma in some patients.
