    Background: Specialized foods, based on aminoacids without phenilalanin, are the main source of protein for patients with phenilketonuria of all ages. Based on modern technologies, new Russian-made foods were created. They have an optimized aminoacid and micronutrient composition, which increases their bioavailability.Objective: Our aim was to investigate the clinical efficiency of the new Russian-made specialized foods based on aminoacids without phenylalanine, in patients with phenylketonuria.Methods: Evaluating physical, somatic and neuropsychic development as well as measuring phenylalanine blood level were carried out twice: before the prescription and after 1 month of using the new Russian-made specialized foods. The chemical composition of the ration was controlled using dietology methods.Results: 57 children at the age of 14 days to 15 years with phenylketonuria (which was detected in neonatal screening) were picked for this study. A hypophenylalanine diet has been prescribed for all children no later than at the age of 3 months of life. In children of the first year (I group) (among which there were children with high phenylalanine blood levels) phenylalanine concentration decreased from 5,5 (4,0; 21,0) to 4,4 (3,7; 4,7) mg/dl (p = 0,014) while using Russian-made specialized foods. In this group of children the psychomotor and physical indices improved. In early childhood-, preschool- and school-aged patients phenylalanine blood level remained steady. The chemical composition of the ration with Russian-made foods, based on aminoacids without phenylalanine, corresponded to the reference intake of main nutrients and energy.Conclusion: Hypophenylalanine diet with new Russian-made specialized foods without phenylalanine (which is designed for phenylketonuria patients of various age groups) showed high clinical efficiency of these foods.Специализированные продукты на основе аминокислот без фенилаланина — главный источник белка для больных фенилкетонурией всех возрастов. Благодаря развитию современных технологий созданы новые отечественные продукты с оптимизированным аминокислотным и микронутриентным составом, что повышает их биологическую ценность.Цель исследования: изучить клиническую эффективность новых отечественных специализированных продуктов питания на основе аминокислот без фенилаланина у больных фенилкетонурией.Методы: оценка физического, соматического и нервно-психического развития, а также определение уровня фенилаланина в крови проводились дважды: до назначения и через 1 мес применения новых отечественных специализированных продуктов. Химический состав рациона определяли с помощью диетологических методов.Результаты: в исследовании участвовали 57 детей в возрасте от 14 дней жизни до 15 лет с фенилкетонурией, выявленной в ходе неонатального скрининга. Гипофенилаланиновая диета была назначена всем детям не позднее 3-го мес жизни. У детей первого года жизни (I группа), среди которых были младенцы с высоким уровнем фенилаланина в крови, на фоне использования отечественных специализированных продуктов концентрация ароматической аминокислоты снизилась с 5,5 (4,0; 21,0) до 4,4 (3,7; 4,7) мг/дл (р = 0,014), в этой группе детей также улучшились показатели психомоторного и физического развития. У пациентов раннего, дошкольного и школьного возраста содержание фенилаланина в крови оставалось стабильным. Химический состав рациона с использованием отечественных продуктов на основе аминокислот без фенилаланина соответствовал рекомендуемым нормам потребления основных пищевых веществ и энергии.Заключение: гипофенилаланиновая диета с применением новых отечественных специализированных продуктов без фенилаланина, предназначенных для больных фенилкетонурией различных возрастных групп, показала их высокую клиническую эффективность
