Мукополисахаридоз III типа (синдром Санфилиппо) является редким мультисистемным заболеванием, обусловленным накоплением гликозаминогликанов в клетках различных органов, приводящим к нарушению их функции, специфическим фенотипическим признакам и прогрессирующим нейрокогнитивным нарушениям. Нейронопатические проявления лидируют в клинической картине болезни как по времени манифестации, так и по тяжести. В большинстве случаев на первом и даже втором годах жизни дети имеют нормальное развитие или неотчетливо выраженные отклонения. В отсутствие заместительной ферментотерапии при данном типе мукополисахаридоза быстро развивается грубая задержка интеллектуального и речевого развития, наблюдаются рецидивирующие респираторные эпизоды в виде пневмоний и бронхообструкций, ребенок рано инвалидизируется. Полиморфизм и неспецифичность клинических проявлений, отсутствие настороженности врачей к орфанным заболеваниям являются частой причиной поздней диагностики мукополисахаридоза. В статье представлен обзор данных о распространенности, генетических и фенотипических вариантах мукополисахаридоза III типа, особенностях ведения пациентов и представление клинического наблюдения ребенка с данной патологией.</p></sec><sec><title>Клиническое наблюдение</title><p>Клиническое наблюдение. Представлено собственное пролонгированное клиническое наблюдение случая мукополисахаридоза III типа у пациента, находившегося под нашим наблюдением в течение 12 лет. Диагноз установлен и подтвержден в возрасте трех лет. Заболевание манифестировало психоневрологическим регрессом и системными соматическими проявлениями. В динамике у ребенка прогрессировали моторный дефицит, когнитивные нарушения с развитием деменции и рецидивирующий аспирационный синдром.</p></sec><sec><title>Заключение</title><p>Заключение. Классическую клиническую картину мукополисахаридоза III типа отличает агрессивное развитие когнитивных и двигательных нарушений на 2–3-м году жизни, характерные фенотипические и соматические проявления болезни. Данный случай демонстрирует множественность проблем и необходимость взаимодействия врачей различных специальностей.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Mucopolysaccharidosis type III (Sanfilippo syndrome) is a rare multi-stem disease caused by the accumulation of glycosaminoglycans (GAG) in the cells of various organs, leading to a violation of their function, specific phentopic signs and progressive neurocognitive disorders. Neurologic manifestations are leading in the clinical picture of the disease, as by the time of manifestation, and by severity. In most patients, in the first and even second years of life, children have normal development or indistinctly pronounced deviations. In the absence of substitute enzyme therapy for this type of MPS, a severe delay in intellectual and speech development develops rapidly, recurrent respiratory episodes in the form of pneumonia and bronchial obstruction are observed, the child is disabled early. Polymorphism and non-specificity of clinical manifestations, lack of alertness of doctors to orphan diseases are a common cause of late diagnosis of MPS. The article presents an overview of data on the prevalence, genetic and phenotypic variants of type III mucopolysaccharidosis, features of patient management and presentation of clinical observation of a child with this pathology.</p></sec><sec><title>Clinical observation</title><p>Clinical observation. We present our own prolonged clinical observation of a type III MPS case in a patient who has been under our supervision for 12 years. The diagnosis was established and confirmed at the age of three years. The disease was manifested by neuropsychiatric regression and systemic somatic manifestations. Motor deficits, cognitive impairments with the development of dementia and recurrent aspiration syndrome progressed in the dynamics of the child.</p></sec><sec><title>Conclusions</title><p>Conclusions. The classical clinical picture of type III MPS is distinguished by the aggressive development of cognitive and motor disorders at 2–3 years of life, characteristic phenotypic and somatic manifestations of the disease. This case demonstrates the multiplicity of problems and the need for interaction between doctors of various specialties.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>синдром Санфилиппо</kwd><kwd>мукополисахаридоз</kwd><kwd>дети</kwd><kwd>нейрокогнитивные нарушения</kwd><kwd>лизосомная болезнь накопления</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Sanfilippo syndrome</kwd><kwd>mucopolysaccharidosis</kwd><kwd>children</kwd><kwd>developmental delay</kwd><kwd>lysosomal storage 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">Benetó N., Vilageliu L., Grinberg D., Canals I.
