Anaphylaxis to grand keyhole limpet (abalone-like shellfish) and abalone.

We report five patients who developed moderate to severe anaphylactic reactions induced by the ingestion of grand keyhole limpet (GKL) and abalone. Specific IgE-mediated hypersensitivity to these shellfish was demonstrated by history, prick skin test, and RAST. RAST inhibition technique revealed the cross-antigenicity between GKL, abalone, and keyhole limpet hemocyanin.

Zinc from oyster tissue as causative factor in mouse deaths in official bioassay for paralytic shellfish poison.

Toxicity (extreme weakness, body temperature drop, cyanosis, some slow deaths) in test mice, upon intraperitoneal injection of standard-method paralytic shellfish poison (PSP) extracts of some PSP-free oysters, is consistent with the relatively high levels of zinc in these extracts. As a rough guideline, the threshold for a toxic response corresponds to a drained tissue zinc level of over 900 micrograms/g. The identification of zinc as the substance responsible has been supported by inducing toxicity in control extracts by spiking with nontoxic levels of zinc, and by eliminating toxicity from toxic extracts by chemical removal (precipitation, ion exchange) of metals.

["Paralytic shellfish poisoning" (author's transl)].

In October 1976 an epidemic of 120 cases of paralytic shellfish poisoning was recorded in western Europe. Analysis of the 23 cases seen in Swizterland shows the following data; paresthesia of mouth and lips (100%); cerebellar syndrome (86%) with giddiness, ataxia, dysmetry and floating sensation; paresia or paralysis (62%); digestive symptoms (14%); no death. The mean incubation time is 3 hs 30 min; mean duration of the symptoms is 2 days. Half of the patients complain of asthenia and moderate memory disturbance lasting up to 3 weeks. The severity of the illness is in relation to the amount of ingested neurotoxin. The epidemiologic study shows that all European cases were due to consumption of mussels from the Atlantic coast of Spain.

Exercise-induced anaphylactic reaction to shellfish.

The syndrome of immediate type I food hypersensitivity, mediated by tissue-bound IgE antibody and mast cell histamine release, is well recorded in the medical literature. This case study represents a previously undescribed late food hypersensitivity, induced only by strenuous exercise. Identification of this new syndrome illustrates classical epidemiologic analysis, improves medical advice for the allergic and athletically inclined, and raises new questions in the areas of allergy and immunology.
