Today, in some variants in the DMD gene, etiopathogenetic therapy is possible to increase the patient’s life expectancy and improve his quality of life.</p><p><bold>Aim.</bold> To evaluate the dynamics of assess the dynamics of the ability to walk independently in patients with DMD caused by a nonsense variant in the DMD gene on the background of therapy with the drug ataluren.</p><p><bold>Materials and methods.</bold> The study included 9 patients with DMD caused by nonsense variants in the DMD gene. Of them, 3 patients were brothers and lost the ability to walk, 6 patients at the ambulatory stage of the disease received therapy with the drug ataluren according to the standard scheme. The six-minute walk test was chosen as the main parameter to assess the treatment efficacy in comparison with the baseline values before treatment.</p><p><bold>Results.</bold> According to the data of six-minute walk test during the observation period 5 patients taking ataluren during 18–36 months retained the ability to move independently. One patient who initially walked 12 m lost ambulation 6 months after starting ataluren therapy. Compared with 3 non-ambulatory brothers with DMD due to the DMD nonsense gene variant who did not receive ataluren, 3 younger brothers on ataluren therapy retained ambulation at an age when the older brothers had already become non-ambulatory.</p><p><bold>Conclusion. </bold>Pathogenetic therapy with the drug ataluren slows down the clinical course of DMD caused by a nonsense variant in the DMD gene with preservation of ambulatory capacity and is characterized by good tolerability.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение</bold>. Мышечная дистрофия Дюшенна (МДД) – X-сцепленное рецесcивное наследственное заболевание, обусловленное вариантами в гене DMD, приводящее к тяжелой инвалидизации и смерти в молодом возрасте. В настоящее время при некоторых вариантах в гене DMD возможна этиопатогенетическая терапия, позволяющая увеличить продолжительность жизни больного и улучшить качество его жизни.</p><p><bold>Цель исследования</bold> – оценить динамику способности к самостоятельной ходьбе у пациентов с МДД, обусловленной нонсенс-вариантом в гене DMD, на фоне терапии препаратом аталурен.</p><p><bold>Материалы и методы.</bold> В исследование включены 9 пациентов с МДД, обусловленной нонсенс-вариантами в гене DMD. Из них 3 пациента были братьями и утратили способность ходить, 6 пациентов на амбулаторной стадии болезни получали терапию аталуреном по стандартной схеме. В качестве основного параметра оценки эффективности лечения выбран тест 6-минутной ходьбы в сравнении с исходными значениями до начала лечения.</p><p><bold>Результаты.</bold> По данным теста 6-минутной ходьбы, за время наблюдения 5 амбулаторных пациентов, принимающих аталурен в течение 18–36 мес, сохранили способность самостоятельно передвигаться. Один пациент, исходно проходивший 12 м, утратил амбулаторность через 6 мес от начала терапии аталуреном. По сравнению с 3 неамбулаторными братьями с МДД, обусловленной нонсенс-вариантом в гене DMD, не получавшими аталурен, 3 младших брата на фоне терапии аталуреном сохранили амбулаторность в том возрасте, когда старшие уже стали неамбулаторными.</p><p><bold>Выводы.</bold> Патогенетическая терапия препаратом аталурен замедляет клиническое течение МДД, обусловленной нонсенс-вариантами в гене DMD, с сохранением амбулаторности пациентов и характеризуется хорошей переносимостью.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Duchenne muscular dystrophy</kwd><kwd>nonsense variant</kwd><kwd>nonsense mutation</kwd><kwd>ataluren</kwd><kwd>six-minute walk test</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>мышечная дистрофия Дюшенна</kwd><kwd>нонсенс-вариант</kwd><kwd>нонсенс-мутация</kwd><kwd>аталурен</kwd><kwd>тест 6-минутной ходьбы</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>WHO motor development study: windows of achievement for six gross motor development milestones.
