Мукополисахаридоз (МПС) II типа — Х-сцепленное наследственное заболевание из группы лизосомных болезней накопления, при котором снижение/отсутствие активности фермента идуронат-2-сульфатазы приводит к нарушению распада гликозаминогликанов (ГАГ). Накопление ГАГ в лизосомах ведет к нарушению функции различных тканей и органов. Различают нейропатическую (тяжелую) и ненейропатическую (относительно легкую) формы заболевания. Диагностика ненейропатической формы МПС II в раннем возрасте является сложной задачей, поскольку заболевание медленно прогрессирует, а ранние симптомы малозаметны. Описание клинических случаев. В статье приведено описание трех клинических случаев ненейропатической формы МПС II. У больных отмечены негрубые изменения черт лица по типу гаргоилизма, гепатомегалия, грыжи, рецидивирующие отиты, невоспалительные контрактуры суставов, поражение клапанов сердца. Рост детей соответствовал возрасту или был чуть ниже референсных значений. Описываемую форму МПС II характеризовало отсутствие когнитивных нарушений. Заключение. Показана эффективность ферментозаместительной терапии: отмечено выраженное улучшение клинической симптоматики, замедление прогрессирования болезни и значительное улучшение качества жизни.</p></abstract><trans-abstract xml:lang="en"><p>Background. Mucopolysaccharidosis (MPS) type II is an X-linked hereditary disease from the lysosomal storage diseases group. The absence or malfunctioning of the iduronate-2-sulfatase enzyme leads to disruption in glycosaminoglycans (GAG) degradation. The GAG accumulation in lysosomes leads to dysfunction of various tissues and organs. There are neuropathic (severe) and non-neuropathic (relatively mild) forms of the disease. Early diagnostics of non-neuropathic form of MPS II is quite difficult due to slow disease progression and because early symptoms are hard to notice. Clinical Cases Description. This article describes three clinical cases of non-neuropathic form of MPS II. Patients had following symptoms: non-rough facial features changes (gargoylism), hepatomegaly, hernias, recurrent otitis, non-inflammatory joint contractures, and cardiac valves involvement. The children height conformed to the age or was little lower than reference values. The described form of MPS II is characterized with the absence of cognitive impairment. Conclusion. Enzyme replacement therapy efficacy has been shown via disease progression slowing down, significant improvement of clinical symptoms and quality of life.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>дети</kwd><kwd>лизосомные болезни накопления</kwd><kwd>мукополисахаридоз II типа</kwd><kwd>ненейропатическая форма</kwd><kwd>ферментозаместительная терапия</kwd><kwd>идурсульфаза</kwd></kwd-group><kwd-group xml:lang="en"><kwd>children</kwd><kwd>lysosomal storage diseases</kwd><kwd>mucopolysaccharidosis type II</kwd><kwd>non-neuropathic form</kwd><kwd>enzyme replacement therapy</kwd><kwd>idursulfase</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Статья опубликована при финансовой поддержке компании TAKEDA.</funding-statement><funding-statement xml:lang="en">The article has been funded by TAKEDA.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Demydchuk M, Hill C., Zhou A, et al.
