I-FABP экспрессируется исключительно в тонкой кишке и высвобождается из клеток после повреждения тканей кишечника.</p><p>Цель работы — определить изменения уровней I-FABP у детей с расстройствами аутистического спектра (РАС) в зависимости от их приверженности к соблюдению безглютеновой диеты.</p><sec><title>Материалы и методы</title><p>Материалы и методы. Обследованы 85 детей в возрасте 3–15 лет с установленными РАС. Первую группу составили 36 пациентов с аутизмом, приверженных к соблюдению безглютеновой диеты более 6 мес, 2-ю — 49 детей с РАС, не имеющих диетических ограничений. Значимых возрастных различий между обследованными детьми не выявлено. У всех пациентов проведен анализ содержания I-FABP в крови.</p></sec><sec><title>Результаты</title><p>Результаты. Установлено, что дети, использующие диетотерапию, имеют более низкие показатели проницаемости кишечника. Средние уровни I-FABP в крови у детей с РАС, соблюдавших безглютеновую диету, составили 156,20 ± 102,16 пг/мл, при несоблюдении диетотерапии средние концентрации I-FABP в крови были равны 528,26 ± 255,95 пг/мл. В связи с тем, что I-FABP является маркёром проницаемости тонкого кишечника, можно полагать, что детей с РАС, не придерживающихся безглютеновой диеты, проницаемость кишечника выше, чем у сверстников с аутизмом, длительно исключающих глютен из рациона питания.</p></sec><sec><title>Обсуждение</title><p>Обсуждение. Необходимо проведение исследований для определения значения изменений концентраций I-FABP в этиологии и клинике РАС у детей. Перед использованием диетотерапии всем пациентам с аутизмом нужно рекомендовать консультацию гастроэнтеролога для определения необходимости соблюдения безглютеновой диеты и динамического контроля её эффективности в случае использования.</p></sec><sec><title>Финансирование</title><p>Финансирование.

Autism spectrum disorders are a widespread pathology, but the etiological factors of their occurrence have not yet been established. The aim of the study was to compare the levels of I-FABP in children with autism spectrum disorders, depending on the adherence to a gluten-free diet.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The study included 36 patients with autism committed to a gluten-free diet for more than six months and 49 patients with autism spectrum disorders who did not have dietary restrictions. There are no statistically significant age differences between the groups. The patients were evaluated and compared with the level of intestinal protein binding fatty acids.</p></sec><sec><title>Results</title><p>Results. Children using diet therapy were found to have significantly lower intestinal permeability. In particular, the average level of I-FABP in children with autism spectrum disorders followed a gluten-free diet is 156.20 ± 102.16 pg/ml, with non-compliance with diet therapy. The average value of the index is diagnosed at the level of 528.26 ± 255.95 pg/ml because the protein binding fatty acids are a marker of small intestine permeability. Children with autism spectrum disorders without adherence to a gluten-free diet show intestinal permeability higher than that of their peers with autism, who long exclude gluten from the diet.</p></sec><sec><title>Conclusions</title><p>Conclusions. Further research is needed to assess the significance of the intestinal fatty acid-binding protein in the etiology and clinical presentation of various diseases, particularly in autism spectrum disorders. Before using diet therapy, all patients with autism need to consult a gastroenterologist to objectively assess the need for its compliance and dynamic monitoring of its effectiveness in case of use.</p></sec><sec><title>Acknowledgment</title><p>Acknowledgment.
