Tropomyosins sensitization causes a life-threatening allergic reaction up to anaphylaxis after eating seafood. Identifying the source of primary sensitization is important to predict the allergic reaction severity. This article describes a clinical case of chronic recurrent urticaria in an 8-year-old boy with tropomyosins sensitization.</p> <p>An 8-year-old boy was diagnosed with the following: controlled atopic phenotype bronchial asthma, food allergy (oral allergy syndrome), and chronic recurrent spontaneous urticaria. Component diagnostics revealed IgE-aB to tropomyosins in high concentrations from 38.79 to 43.38 kUA/l and cat and dog uteroglobin and lipocalins in high concentrations from 7.79 to 43.38 kUA/l.</p> <p>It is necessary to specify the primary sensitizer to analyze the clinical significance of allergens that provoke sensitization to various groups of allergens. In this case, sensitization to tropomyosins is most likely described as caused by either a helminthic invasion or midge bites. Therefore, food allergic reactions to tropomyosins caused from crustaceans were not observed.</p></abstract><trans-abstract xml:lang="ru"><p>Тропомиозины ― это семейство аллергенных белков, которые содержатся в большом количестве в организме каждого беспозвоночного животного. Сенсибилизация к тропомиозинам может стать причиной жизнеугрожаемой аллергической реакции вплоть до анафилаксии после употребления морепродуктов. Выявление источника первичной сенсибилизации важно для прогнозирования тяжести аллергической реакции.</p> <p>У мальчика в возрасте 8 лет диагностированы бронхиальная астма, атопический фенотип, контролируемая; пищевая аллергия (синдром оральной аллергии); хроническая рецидивирующая спонтанная крапивница. Методом компонентной диагностики выявлены в высоких концентрациях антитела изотипа IgE к тропомиозинам (от 38,79 до 43,38 kUA/l), к утероглобину и липокалинам кошки и собаки (от 7,79 до 43,38 kUA/l).</p> <p>При анализе клинического значения аллергенов, вызывающих сенсибилизацию к различным группам аллергенов, необходимо конкретизировать первичный сенсибилизатор. В описанном нами случае, вероятнее всего, сенсибилизация к тропомиозинам была обусловлена либо перенесённой глистной инвазией, либо укусами гнуса, поэтому пищевых аллергических реакций на тропомиозины, источником которых были ракообразные, не наблюдали.</p></trans-abstract><kwd-group xml:lang="en"><kwd>case report</kwd><kwd>component-resolved diagnosis</kwd><kwd>tropomyosins</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>клинический случай</kwd><kwd>молекулярная аллергодиагностика</kwd><kwd>тропомиозины</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Matricardi PM, Kleine-Tebbe J, Hoffmann HJ, et al.
