| Popis: | Introduction Histamine intolerance (HI) is a disorder associated with an impairment of ability to metabolize ingested histamine. The incidence of HI in general population is 1-3%. Clinical manifestation of HI contains nonspecific predominantly gastrointestinal, but also extraintestinal symptoms. HI could be primary with genetic predisposition, or secondary with lower activity of diaminooxidase (DAO) without positive genetic screening. Objectives This study aims to evaluate the prevalence of HI by patients with anxiety disorders. HI can imitate anxiety symptoms, therefore we predict higher prevalence HI in patients with anxiety disorders than in general population. Methods It is observational cross-sectional study on cohort of anxious patients for detecting the prevalence of HI. Patients were screened by scale for histamine intolerance questionnaire. Patients with positive questionnaire were examined for serum DAO and genetically examined. Results 113 patients fulfilled the HI questionnaire. From this cohort 35.4% (40 subjects) were positive at screening. Biomarkers of HI were screened only in case of positivity in this questionnaire. Table No. 1: Results of our study from cohort with positive screening, 35.4 % (40 subjects).
