Exercise-induced anaphylaxis
Exercise-induced anaphylaxis (EIA, EIAn, EIAs) is a rare condition in which anaphylaxis, a serious or life-threatening allergic response, is brought on by physical activity. Approximately 5–15% of all reported cases of anaphylaxis are thought to be exercise-induced.
The exact proportion of the population with EIA is unknown, but a 2001 study of 76,229 Japanese junior high students showed that the frequency of EIA was 0.031%.
Exercise-induced anaphylaxis is not a widely known or understood condition, with the first research on the disorder only having been conducted in the past 40 years. A case report in 1979 on EIA was the first research of its kind, where a patient was described to experience anaphylactic shock related to exercise 5–24 hours following the consumption of shellfish.
The condition is thought to be more prevalent in women, with two studies of EIA patients reporting a ratio of 2:1 for females:males with the disorder. There is, however, thought to be no link to ethnicity.
Survey results from EIA patients have shown that the average number of attacks per year is 14.5. However, most sufferers of EIA report that both severity and frequency of attacks decrease over time.
The anaphylaxis campaign splits symptoms of EIA into two categories: mild and severe. Mild symptoms may include "widespread flushing of the skin", hives or urticaria, swelling of the body (angioedema), swelling of the lips, and nausea or vomiting. More severe symptoms might include the swelling of the tongue, difficulty in swallowing or breathing, constriction of the airways, feeling faint, and unconsciousness.
Symptoms can start immediately following exercise, but 90% of patients report experiencing an attack 30 minutes following activity.
A paper by Sheffer and Austen (1980) splits an EIA event into four distinct stages: prodromal, early, fully developed, and late. Characteristic symptoms of the prodromal stage include redness and itching. In the early stage, generalised urticaria develops. If the reaction does not diminish, it may become fully developed EIA, in which gastrointestinal symptoms and constriction of the airway may occur. The late phase, which follows recovery from the reaction, includes frontal headaches and a feeling of fatigue; these symptoms may manifest themselves up to 72 hours following onset of the reaction.
