Animal bite anaphylaxis, rarely diagnosed but underappreciated.

BACKGROUND: Animal allergies are common, with reactions ranging from rhinoconjunctivitis from respiratory exposure to anaphylaxis, usually from animal bites. Since animal bites are also common, this raises the question of how often anaphylaxis occurs following a bite. MATERIALS AND METHODS: A PubMed, Google, and Google Scholar literature review was performed using keywords such as animal bite anaphylaxis. An inquiry was made to the Anaphylaxis Registry ANAPHYLAXIE.net to see if additional cases were contained in the registry. RESULTS: Approximately 40 cases of animal bite anaphylaxis are described in the literature, mostly from rodent bites (mice, rats, hamsters, and guinea pigs). A survey of laboratory animal bite anaphylaxis in the U.S. identified previously unreported cases, suggesting that most cases are not reported. CONCLUSION: Anaphylaxis from animal bites is rarely reported, but occurs more frequently than suggested by case reports and should be considered in a symptomatic patient following a bite.
