Angioedema, rhinitis and asthma provoked by fishing bait (Eisenia foetida)

The Eisenia foetida is an earthworm that is used as fishing bait in river fishing. We report a case of facial angioedema, rhinitis and asthma in an amateur fisherman who used this worm (Eisenia foetida) as fishing bait when fishing in rivers. However, the manifestations of dermo-respiratory hypersensitivity did not arise when he used other fishing bait (Tenibrio molitor and Marphysa sanguinea) in open-sea fishing. "In vivo" and "in vitro" tests using a battery of the usual neumoallergens and food (fish) were negative. Consequently, extracts of Eisenia foetida, Tenibrio molitor and Marphysa sanguinea were prepared. Skin tests, nasal challenge, histamine release curve and levels of specific IgE were positive when using an extract of Eisenia foetida. These parameters, however, were negative for beetle larvae (Tenibrio molitor) and marine worm (Marphysa sanguinea). The allergo-immunological study was also negative for the group of healthy and atopic controls when using these three extracts of fishing bait. The rarity of the allergen responsible for this dermo-respiratory picture stresses the need to include, on occasions, not only insects but also worms in the battery of the usual neumoallergens.
