Abstract

Histamine intolerance (HIT) is a non-immunological disorder associated with an impaired ability to metabolize ingested histamine. Manifestation of HIT includes gastrointestinal and non-gastrointestinal symptoms. Clinical symptoms of HIT are non-specific and can imitate different diseases such as allergies, food intolerance, mastocytosis and other. The diagnosis of HIT is difficult. There are several candidate tests to detect DAO insufficiency, but their informative value is questionable. Currently, a positive clinical effect of a low-histamine diet is the most important for establishing the diagnosis. Equally in the treatment, a low-histamine diet is the most crucial approach. Other therapeutic options such as DAO supplementation treatment with antihistamines or probiotics are considered as complementary treatments. Our article provides a review on histamine intolerance, focusing on etiology and the diagnostic and treatment possibilities.

Keywords: diamine oxidase (DAO); histamine intolerance; histamine intoxication.
