Мукополисахаридоз, тип I (МПС I) — заболевание из группы лизосомных болезней накопления, возникающее вследствие мутаций в гене IDUA, что приводит к накоплению гликозаминогликанов (ГАГ) в органах и тканях. Поражение суставов при данном заболевании носит системный, прогрессирующий характер.</p></sec><sec><title>Цель исследования</title><p>Цель исследования. В настоящее время актуальной, но нерешенной задачей является исследование влияния различных видов патогенетической терапии на состояние костно-суставной системы у пациентов с МПС I с тяжелыми и мягкими фенотипами с целью предотвращения дальнейшего прогрессирования патологии суставов.</p></sec><sec><title>Методы</title><p>Методы. В исследование были включены 46 пациентов с установленным диагнозом «мукополисахаридоз, тип I», из них 35 — с тяжелым фенотипом (синдром Гурлер) и 11 детей с мягким фенотипом (синдромы Гурлер–Шейе и Шейе). Пациентам проводилась оценка возраста начала клинических проявлений со стороны костно-суставной системы, состояния крупных и мелких суставов, наличия стеноза шейного отдела позвоночника в зависимости от проводимой терапии.</p></sec><sec><title>Результаты</title><p>Результаты. Патология костно-суставной системы наблюдается у всех больных с МПС I — как с мягким, так и с тяжелым фенотипом. Контрактуры плечевых, локтевых, лучезапястных суставов и мелких суставов кисти выявлены у большинства пациентов с синдромом Гурлер независимо от проводимой терапии. Патология тазобедренных суставов встречалась у детей, получавших: ферментозаместительную терапию (ФЗТ) — в 46,7% случаев, трансплантацию гемопоэтических стволовых клеток (ТГСК) в сочетании с ФЗТ — в 34,4% случаев. У пациентов с синдромом Гурлер, находящихся на лечении ТГСК в сочетании с ФЗТ, стеноз шейного отдела встречался статистически значимо более редко (p = 0,018) по сравнению с пациентами, получавшими только ФЗТ. Пациенты с синдромом Гурлер, находящиеся на терапии ФЗТ, имели статистически значимо более низкие показатели роста, чем пациенты после ТГСК в сочетании с ФЗТ. У детей с мягким фенотипом наиболее часто встречалось поражение локтевых, лучезапястных, коленных суставов и мелких суставов кисти — в 90% случаев.</p></sec><sec><title>Заключение</title><p>Заключение. Комбинированная терапия (ТГСК и ФЗТ) у пациентов с синдромом Гурлер снижает тяжелые проявления со стороны опорно-двигательного аппарата, включая детей, у которых выявлен патогенный нуклеотидный вариант c.208C&gt;T в гомозиготном состоянии.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Mucopolysaccharidosis type I is disease from the group of lysosomal storage disease developing due to mutations in the IDUA gene. It leads to the accumulation of glycosaminoglycans (GAGs) in organs and tissues. Joints damage in this disease is systemic and progressive.</p></sec><sec><title>Objective</title><p>Objective. The aim of the study. Nowadays, relevant issue is to investigate the effects of various types of pathogenetic therapy on the state of the osteoarticular system in patients with severe and mild phenotypes of MPS I to prevent further progression of joint pathology.</p></sec><sec><title>Methods</title><p>Methods. The study included 46 patients diagnosed with “mucopolysaccharidosis type I”. 35 children had severe phenotype (Hurler syndrome) and 11 — with mild phenotypes (Hurler-Scheie and Scheie syndromes). The onset age of clinical manifestations in osteoarticular system, the state of large and small joints, and the presence of cervical stenosis according to the therapy were evaluated in these patients.</p></sec><sec><title>Results</title><p>Results. The osteoarticular system pathology can be usually revealed in all patients with MPS I, in both mild and severe phenotypes. The contractures of shoulder, ulnar, wrist, and small hand joints have been revealed in most patients with Hurler syndrome, regardless of the administered therapy. Hip joints pathology was observed in children who was administered with: enzyme replacement therapy (ERT) — in 46.7% of cases, hematopoietic stem cell transplantation (HSCT) in combination with ERT — in 34.4% of cases. Patients with Hurler syndrome administered with HSCT in combination with ERT had cervical stenosis statistically significantly more rarely (p = 0.018) compared to patients treated with ERT only. Patients with Hurler syndrome who were on ERT had statistically significantly lower growth rates than patients after HSCT in combination with ERT. Lesions in ulnar, wrist, knee and small hand joints were the most common in children with mild phenotypes (in 90% of cases).</p></sec><sec><title>Conclusion</title><p>Conclusion. Combined therapy (HSCT and ERT) in patients with Hurler syndrome reduces severe manifestations in osteoarticular system, including children with a pathogenic nucleotide variant c.208C&gt;T in a homozygous state.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>мукополисахаридоз</kwd><kwd>тип I</kwd><kwd>синдром Гурлер</kwd><kwd>синдром Шейе</kwd><kwd>альфа-L-идуронидаза</kwd><kwd>к онтрактуры суставов</kwd><kwd>множественный дизостоз</kwd><kwd>ферментозаместительная терапия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>mucopolysaccharidosis type I</kwd><kwd>Hurler syndrome</kwd><kwd>Scheie syndrome</kwd><kwd>alpha-L-iduronidase</kwd><kwd>joint contractures</kwd><kwd>multiple dysostosis</kwd><kwd>enzyme replacement therapy</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">Villoria JG, Pajares S, Lopez RM, et al.
