Такая частота, а также возможность проведения эффективной терапии ряда нозологических форм, создают предпосылки к активному изучению метаболических заболеваний. Для ряда наследственных болезней обмена веществ характерны острое и ранее начало в первые дни или месяцы жизни ребенка и агрессивное течение с высокой вероятностью развития летального исхода. Такое течение болезни требует быстрой разработки стратегии обследования и лечения пациента. В группу болезней с ранним и острым началом входит лейциноз или болезнь с запахом кленового сиропа мочи, который относится к нарушениям обмена аминокислот (аминоацидопатиям). Учитывая низкую распространенность каждой нозологической формы собрать большую выборку пациентов с конкретным заболеванием   очень сложно. Поэтому описание даже отдельно взятого случая представляет клинический интерес. В данной статье приведены краткие данные о распространенности, патогенезе, клинической картине и лечении болезни с запахом кленового сиропа мочи.  Также представлен клинический случай пациента с классическим течением лейциноза из собственной практики.</p></abstract><trans-abstract xml:lang="en"><p>Inborn errors of metabolism are an extensive group of congenital diseases, collectively affecting up to 2-3 % of the population. Anumber of hereditary metabolic diseases is characterised by an acute and earlier beginning in the first days or months of a child’s life and anaggressive course with a high probability of mortality. This course of the disease requires a rapid development of a strategy for the examination and treatment of the patient. The article presents a clinical example of a child with maple syrup urine disease. Given the rare frequency, it is very difficult to collect and analyze a large group of patients with leucinosis. Therefore, the description of even a single case is of clinical interest and is useful for highlighting the medical audience.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>наследственные болезни обмена веществ</kwd><kwd>нарушение метаболизма</kwd><kwd>лейциноз</kwd><kwd>болезнь с запахом кленового мочи</kwd></kwd-group><kwd-group xml:lang="en"><kwd>inborn errors of metabolism</kwd><kwd>metabolic disorders</kwd><kwd>leucinosis</kwd><kwd>maple syrup urine disease</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Ferreira C.R., van Karnebeek C.D.
