Синдром Гурлер (мукополисахаридоз, тип I) — редкое наследственное заболевание, имеющее хроническое течение. Основными методами терапии синдрома Гурлер являются трансплантация гемопоэтических стволовых клеток (ТГСК) и ферментозаместительная терапия (ФЗТ). В последние годы при прогрессировании заболевания показала свою эффективность комбинированная терапия — применение ФЗТ как перед проведением ТГСК, так и после. Описание клинических случаев. Представленные клинические случаи показывают эффективность применения ФЗТ у пациентов с синдромом Гурлер после ТГСК, в первом клиническом случае — в связи со снижением активности альфа-L-идуронидазы через 2 года после проведения ТГСК, во втором клиническом случае — в связи с ухудшением состояния пациента, в частности со стороны сердечно-сосудистой и дыхательной систем, развитием гепатомегалии, хотя уровень фермента и содержание гликозаминогликанов в моче пациентки оставались в пределах нормальных значений. Заключение. Комбинированная терапия, которая включает ФЗТ не только до проведения ТГСК, но и при ухудшении клинического состояния пациента после ТГСК, играет большую роль в стабилизации состояния пациента, предотвращении быстрого прогрессирования симптоматики, развития жизнеугрожающих осложнений, особенно со стороны сердечно-сосудистой системы.</p></abstract><trans-abstract xml:lang="en"><p>Background. Hurler syndrome (mucopolysaccharidosis, type I) is a rare hereditary disease with chronic course. The main methods for Hurler syndrome management are hematopoietic stem cell transplantation (HSCT) and enzyme replacement therapy (ERT). In recent years, combination treatment (ERT administration both before and after HSCT) has shown its efficacy in case of disease progression. Clinical case description. The presented clinical cases demonstrate the efficacy of ERT administration in patients with Hurler syndrome after HSCT: in the first clinical case due to the decrease in alpha-iduronidase activity 2 years after HSCT, in the second clinical case due to the aggravation of the patient's condition (cardiovascular and respiratory systems, hepatomegaly, although the level of enzyme and glycosaminoglycans in the patient's urine remained within normal values). Conclusion. Combination treatment including ERT not only before HSCT, but also in case of clinical state worsening after HSCT, plays significant role in stabilizing the patient's condition, preventing rapid progression of symptoms and development of life-threatening complications (especially cardiovascular ones).</p></trans-abstract><kwd-group xml:lang="ru"><kwd>мукополисахаридоз</kwd><kwd>тип I</kwd><kwd>синдром Гурлер</kwd><kwd>трансплантация гемопоэтических стволовых клеток</kwd><kwd>ферментозаместительная терапия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>mucopolysaccharidosis</kwd><kwd>type I</kwd><kwd>Hurler syndrome</kwd><kwd>hematopoietic stem cell transplantation</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">Hampe CS, Wesley J, Lund TC, et al.
