The results provided in this article are obtained in Russia as a part of the multicountry study. Primary variables included Eczema Area and Severity Index, Scoring Atopic Dermatitis and Dermatology Life Quality Index according to the assessment at the single visit performed at the study enrollment in. Patients were prescribed to and administered all treatments irrespectively to the study participation.</p> <p><bold>RESULTS:</bold> A total of<italic> </italic>125 patients were analyzed, 63 of whom received systemic and 62 non-systemic therapy. Mean disease duration was 15.5 ± 14.5 years. In the overall population, Eczema Area and Severity Index, Scoring Atopic Dermatitis and Dermatology Life Quality Index total scores were 9.0 ± 10.1, 32.9 ± 16.1 and 8.9 ± 7.0, respectively, which corresponded to moderate disease severity and moderate effect of atopic dermatitis on quality of life. Disease burden was significantly higher in systemic treatment group <italic>vs</italic> non-systemic: Eczema Area and Severity Index was 12.4 ± 11.5 (moderate) <italic>vs</italic> 5.4 ± 6.8 (mild) (<italic>p</italic> &lt; 0.0001) and Scoring Atopic Dermatitis was 38.6 ± 16.7 <italic>vs</italic> 27.0 ± 13.2 (moderate category for both groups) (<italic>p</italic> &lt; 0.0001), respectively. Impact of the disease on quality of life was also more pronounced (<italic>p</italic> = 0.002) in systemic <italic>vs</italic> non-systemic treatment group with Dermatology Life Quality Index of 10.7 ± 7.1 (very large effect on quality of life) <italic>vs</italic> 7.1 ± 6.4 (moderate effect on quality of life), respectively.</p> <p><bold>CONCLUSION:</bold> According to the data obtained in real-world conditions of the Russian daily clinical practice, patients with atopic dermatitis have a prominent disease burden and impact on quality of life, despite receiving systemic treatment, which is consistent with the wider population of the multinational ESSENTIAL AD study. This reflects the unmet medical need for effective management of patients with moderate to severe atopic dermatitis in Russia.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Актуальность.</bold> Существует ограниченный объем данных реальной клинической практики о бремени атопического дерматита у пациентов, получающих системную или несистемную терапию в России.</p> <p><bold>Цель исследования —</bold> оценить тяжесть симптомов атопического дерматита и качество жизни пациентов, получающих системную и несистемную терапию в условиях рутинной клинической практики.</p> <p><bold>Методы.</bold> ESSENTIAL AD — кросс-секционное наблюдательное ретроспективное исследование с обзором медицинских карт взрослых пациентов (18–65 лет) с подтвержденным диагнозом атопического дерматита. Результаты, представленные в данной статье, получены в России в рамках международного исследования. Основные оцениваемые конечные точки: индекс распространенности и тяжести экземы, индекс степени тяжести атопического дерматита и дерматологический индекс качества жизни. Эти показатели оценивали во время одного визита при включении в исследование. Все виды терапии назначены и получены пациентами независимо от участия в исследовании.</p> <p><bold>Результаты.</bold><italic> </italic>Проанализированы данные 125 пациентов, 63 из которых получали системную терапию, 62 — несистемную. Средняя продолжительность заболевания составила 15,5 ± 14,5 года. В общей популяции сумма баллов по индексу распространенности и тяжести экземы, индексу оценки степени тяжести атопического дерматита и дерматологическому индексу качества жизни составила 9,0 ± 10,1; 32,9 ± 16,1 и 8,9 ± 7,0 соответственно, что свидетельствует о средней степени тяжести заболевания и умеренном влиянии атопического дерматита на качество жизни. Бремя заболевания было статистически значимо выше в группе системной терапии по сравнению с несистемной: сумма баллов по индексу распространенности и тяжести экземы составила 12,4 ± 11,5 (средняя степень) против 5,4 ± 6,8 (легкая степень) (<italic>p</italic> &lt; 0,0001); по индексу оценки степени тяжести атопического дерматита — 38,6 ± 16,7 против 27,0 ± 13,2 (в обеих группах соответствовало средней степени тяжести) (<italic>p</italic> &lt; 0,0001). Влияние заболевания на качество жизни также было более выраженным в группе системной терапии по сравнению с несистемной: сумма баллов по дерматологическому индексу качества жизни составила 10,7 ± 7,1 (сильное влияние) против с 7,1 ± 6,4 (умеренное влияние) соответственно (<italic>p</italic> = 0,002).</p> <p><bold>Заключение.<italic> </italic></bold>Согласно данным, полученным в реальных условиях повседневной клинической практики в России, у пациентов с атопическим дерматитом отмечаются выраженное бремя болезни и ее существенное влияние на качество жизни, несмотря на получение системной терапии, что согласуется с данными более широкой популяции международного исследования ESSENTIAL AD. Это отражает неудовлетворенную потребность в эффективном лечении пациентов со среднетяжелым и тяжелым атопическим дерматитом в России.</p></trans-abstract><kwd-group xml:lang="en"><kwd>atopic dermatitis</kwd><kwd>quality of life</kwd><kwd>severity of illness index</kwd><kwd>burden of disease</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>атопический дерматит</kwd><kwd>качество жизни</kwd><kwd>индекс тяжести заболевания</kwd><kwd>бремя заболевания</kwd></kwd-group><funding-group><funding-statement xml:lang="en">AbbVie sponsored the study; contributed to the design; participated in the data collection, analysis and interpretation; in writing, reviewing, and approval of the final version</funding-statement><funding-statement xml:lang="ru">Исследование спонсировано компанией «ЭббВи», которая также участвовала в разработке его дизайна, сборе, анализе и интерпретации данных, написании, рецензировании и утверждении итоговой версии публикации</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Zietze HA, Augustin M, Kienitz C, et al.
