Представить клиническое наблюдение развития аргинин-янтарной ацидурии (АЯА) у новорожденного.</p></sec><sec><title>Основные положения</title><p>Основные положения. Рассмотрены основные аспекты клинической картины, диагностики, а также принципы лечения АЯА. Частота АЯА составляет 1 случай на 70 000 новорожденных. Причиной является дефект фермента аргининосукцинатлиазы, сопровождающийся накоплением токсических метаболитов. Авторы акцентировали внимание на развитии клинической симптоматики у пациента. С использованием специализированных методов диагностики — газовой хроматографии и тандем-масс-спектрометрии, а также метода массового параллельного секвенирования — у новорожденного поставили диагноз АЯА. Однако поздняя диагностика АЯА, несмотря на проводимую терапию, привела к летальному исходу.</p></sec><sec><title>Заключение</title><p>Заключение. Данный клинический случай демонстрирует важность ранней постановки диагноза у пациентов с врожденным нарушением обмена веществ. Следует помнить, что АЯА — это наследственная патология, диагностировать которую позволяют клиническая симптоматика и использование газовой хроматографии, тандемной масс-спектрометрии, массового параллельного секвенирования.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To present a clinical case of the development of arginine-succinic aciduria (AYAA) of a newborn.</p></sec><sec><title>Key points</title><p>Key points. The main aspects of the clinical performance, diagnosis, as well as the principles of treatment of AYAA are considered. The incidence of ANA is 1 case per 70 000 newborns. The cause is a defect in the enzyme arginine succinathy lyase, accompanied by the accumulation of toxic metabolites. The authors focused on the development of clinical symptoms of the patient. Using specialized diagnostic methods — gas chromatography and tandem mass spectrometry, as well as the method of mass parallel sequencing, despite the therapy, led to death.</p></sec><sec><title>Conclusion</title><p>Conclusion. This clinical case demonstrates the importance of early diagnosis of patients with congenital metabolic disorders. It should be remembered that AYAA is a congenital defect, which can be diagnosed by clinical symptoms and the use of gas chromatography, tandem mass spectrometry, and mass parallel sequencing.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>аргинин-янтарная ацидурия</kwd><kwd>тандем-масс-спектрометрия</kwd><kwd>массовое параллельное секвенирование</kwd><kwd>новорожденный</kwd></kwd-group><kwd-group xml:lang="en"><kwd>arginine-succinic aciduria</kwd><kwd>tandem-mass spectrometry</kwd><kwd>mass parallel sequencing</kwd><kwd>newborn</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Авторы выражают благодарность студентам лечебного факультета ФГБОУ ВО ОрГМУ Минздрава России Л.М.
