The prevalence and variety of clinical manifestations of food hypersensitivity in the population
Barbara Rymarczyk, Joanna Glück, Paulina Jóźwiak, Barbara Rogala

Food and/or food additives may elicit a variety of reactions extending
from mild or moderate symptoms from the skin, respiratory or gastrointestinal
tract, to severe life-threatening anaphylactic reactions.
Aim of the study: The aim of the study was to establish the incidence
and clinical manifestation of food hypersensitivity reactions in
adult subjects from various populations (a big city, a small city, the
countryside) in the Upper Silesia region.
Material and method: 796 subjects (457 women and 339 men,
mean age 41.5±13.9 yrs) with self-reported relationship between the
exposure to one or more certain foods and symptoms, were enrolled
into the study. All of them were asked to answer a few questions
concerning detailed medical history, clinical symptoms of food hypersensitivity
and nutritional habits.
Results: 196 (24,62%) subjects reported adverse reactions to one or
more foods (only reproducible symptoms were taken into consideration).
The most common complaints were: gastrointestinal symptoms
(36.22%), acute urticaria and/or angioedema (34.68%), anaphylaxis
(18.36%), oral allergy syndrome (OAS) (10.22%), and the exacerbation
of atopic dermatitis (9.69%). The most common foodstuffs evoking
adverse reactions were: strawberry (5.02%), cow’s milk (3.28%)
and tree nuts (3.21%). There were 14.2% of the analyzed population
who suffered from at least one atopic disease, and the incidence of
it was significantly higher in the group with food hypersensitivity
history (33.67% vs. 6.44%). The food hypersensitivity group was also
significantly more often affected by drug adverse reactions (26.02%
vs. 5.90%).
Conclusion: A properly prepared questionnaire helps to identify
a subgroup of patients who would mostly benefit from a detailed
food hypersensitivity diagnostics. The most common reported symptom
of food hypersensitivity were abdominal disturbances and acute
urticaria. Atopic diseases and drug hypersensitivity often coexist with
food hypersensitivity.
