VRÁNKOVÁ, Jana
The topic of this thesis is nutrition in patients with histamine intolerance and the general knowledge about this issue in Czechia. The theoretical framework describes the hista-mine function in human body, following chapters are dedicated to the mechanism of histamine intolerance itself, its clinical manifestation, diagnostics and treatment. In the practical part, two goals were established. The first goal was a comparison of knowledge about this issue between general public and expert community. The second goal was to determine knowledge about this topic in patients with histamine intolerance. For the first goal, quantitative research using scored questionnaire was used. This form was answered by 280 respondents from both expert and general public fields. For the second goal, qualitative method was chosen, using a questionnaire with broader scope. The questions were focused on clinical manifestation, diagnostics, treatment and general knowledge regarding histamine intolerance. Sampling in qualitative research consisted of 20 respondents, patients with histamine intolerance. Also, as part of the qualitative research, the diet of the respondents with histamine intolerance was analyzed using "Nutriservis" software. In the quantitative research, comparing awareness of histamine intolerance, the experts proved to be more successful based on the points scored. This difference, however, was not very significant. In the quantitative research, the fundamental results corresponded with the data from other professional studies in this field, citing gastrointestinal issues as the most common. Also, the difficulty in diagnosing HIT was affirmed, given that in 60% of respondents it took years before HIT was diagnosed. The dietary analysis has shown substantially lower energy intake in patients following the initial strict elimination diet. My work can, to some extent, increase the public awareness about histamine intolerance.
