Rhinoconjunctivitis and asthma provoked by Asticot maggots.
Asticot maggots are used as bait by anglers fishing the rivers, reservoirs and coastal waters of Spain. We report the case of a male patient, a keen angler, who used this bait on weekends and suffered allergic reactions that affected his conjunctiva and respiratory system for years. Other baits (earthworms, Eisemia foetida) did not elicit this reaction. In order to confirm the allergic reaction, we used maggots in vivo in the Prick Test, obtaining a positive reaction in 15 to 30 minutes. The patient also had an allergic reaction to house dust mites in prick test. To a lesser extent, he also was sensitive to certain grass pollens (Lollium perenne) and seafood (prawns and squid).
