The study involved 82 patients (57 women and 25 men, mean age 36.4±9.3 years) with a disease duration of 2.2±1.5 years. Seven (9%) patients had secondary progressive MS (SPMS), 6 (7%) had rapidly progressive MS (RPMS) and 69 (84%) had highly active MS (HAMS). According to the instructions for use, oral therapy with cladribine was administered in two short courses (up to 10 days per year) to achieve a long-term effect on the immune system. The dose of cladribine was calculated based on the body weight.</p></sec><sec><title>Results</title><p>Results. The average frequency of exacerbations per year before starting therapy was 1.6, while it decreased to 0.2 during cladribine therapy. An exacerbation was observed in 18 patients (22%) at the end of the first course of cladribine treatment and in one patient (2.6%) after the second treatment course. Thus, the number of exacerbations decreased by 78% after the first year of treatment and by 97.4% after the second year of treatment. The mean EDSS score was 3.2±2.5 points before the start of treatment, 3.6±2.5 points after the first course of treatment and 3.4±2.5 points after the second course (p&gt;0.05). MRI results showed a decrease in disease activity by 83% after the first course of cladribine therapy and by 97.4% after the second course. No serious adverse events occurred in any of the patients.</p></sec><sec><title>Conclusion</title><p>Conclusion. We demonstrated efficacy and safety of cladribine in real-life clinical practice in MS patients with frequent exacerbations and rapid disability progression (SPMS, RPMS, HAMS).</p></sec></abstract><trans-abstract xml:lang="ru"><p>Кладрибин обладает четко определенной активностью в отношении лимфоцитов, которая приводит к их селективному истощению.</p><p>Цель исследования – определение эффективности и безопасности кладрибина в терапии рассеянного склероза (РС) в реальной клинической практике.</p><sec><title>Материал и методы</title><p>Материал и методы. В исследовании приняли участие 82 пациента (57 женщин и 25 мужчин, средний возраст – 36,4±9,3 года) с длительностью заболевания 2,2±1,5 года. У 7 (9%) пациентов был вторично-прогрессирующий тип РС (ВПРС), у 6 (7%) – быстропрогрессирующий РС (БПРС), у 69 (84%) – высокоактивный РС (ВАРС). Согласно инструкции по применению, проводилась пероральная терапия кладрибином двумя короткими курсами (до 10 дней 1 раз в год) для оказания последующего долгосрочного воздействия на иммунную систему. Доза кладрибина рассчитывалась исходя из массы тела.</p></sec><sec><title>Результаты</title><p>Результаты. Средняя частота обострений в год до начала терапии составила 1,6, на фоне терапии кладрибином она снизилась до 0,2. У 18 (22%) пациентов наблюдалось обострение по окончании первого курса терапии кладрибином, у одного пациента (2,6%) – после второго курса. Таким образом, число обострений снизилось на 78% к концу первого года наблюдения и на 97,4% – к концу второго года. До начала терапии нарушения по шкале EDSS составили 3,2±2,5 балла, после первого курса – 3,6±2,5 балла, после второго курса – 3,4±2,5 балла (p&gt;0,05). По результатам МРТ отмечено снижение активности заболевания на 83% после первого курса терапии кладрибином и на 97,4% после второго курса. Ни у одного из наблюдавшихся нами пациентов не зарегистрировано серьезных нежелательных явлений.</p></sec><sec><title>Заключение</title><p>Заключение. В условиях реальной клинической практики в популяции больных РС с частыми обострениями и быстрым нарастанием инвалидизации (ВПРС, БПРС, ВАРС) были продемонстрированы эффективность и безопасность кладрибина.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>кладрибин</kwd><kwd>рассеянный склероз</kwd><kwd>NEDA</kwd><kwd>иммуносупрессия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cladribine</kwd><kwd>multiple sclerosis</kwd><kwd>NEDA</kwd><kwd>immunosuppression</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Статья спонсируется компанией «Мерк»</funding-statement><funding-statement xml:lang="en">The article is sponsored by Merck</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">Browne P, Chandraratna D, Angood C, et al.
