Data on the use of low-temperature argon plasma in combination with phototherapy for non-segmental vitiligo are virtually nonexistent, although the complementary mechanisms of both methods justify their combination.</p> <p><bold>AIM:</bold> To evaluate the efficacy and safety of the combined use of low-temperature argon plasma and UVB-311 nm compared with UVB-311 nm monotherapy in patients with non-segmental vitiligo, based on changes in the VASI (Vitiligo Area Severity Index) and quality of life (Vitiligo-Speciﬁc Quality of Life, VitiQoL) over 8 weeks and 1 month after treatment completion.</p> <p><bold>METHODS:</bold> A prospective, non-randomized, controlled, comparative trial included adult patients with non-segmental vitiligo with depigmented lesions assessed by VASI. A total of 60 patients were included in the study: 28 in the main group and 32 in the control group. In the main group, the median age was 34.5 years [Q1; Q3: 26.0; 44.0], in the control group 36.0 years [28.0; 46.5]; women accounted for 60.7% and 62.5%, respectively. The median duration of the disease in the main group was 4.5 years [2.0; 9.0], in the control group 5.0 years [2.5; 10.0]; a history of five years or more was observed in 42.9% and 50.0% of the participants, respectively. The groups were comparable for all baseline parameters; no statistically significant intergroup differences were found. Patients with segmental and mixed forms of the disease, pregnant women, individuals with photodermatoses, a history of systemic immunosuppressants, and skin cancer were excluded. The main group received low-temperature argon plasma therapy on depigmented lesions using the Plasmoran device, followed by a session of UVB-311 nm. The control group received UVB-311 nm monotherapy. Treatment was administered three times a week for 8 weeks. Evaluations were performed at baseline, after 4 and 8 weeks, and 1 month after completion of therapy.</p> <p><bold>RESULTS:</bold> In the main group, the median VASI score decreased from 3.8 to 2.3 points by week 8 (a 39.5% decrease), and in the control group from 4.1 to 3.1 points (24.4%); the difference between groups was 0.5 points (95% CI 0.04–0.96; <italic>p</italic> = 0.03). After 1 month, the difference remained (2.1 versus 2.9 points, <italic>p</italic> = 0.04). According to VitiQoL, the median score at week 8 was 30.5 versus 35.0 points (<italic>p</italic> = 0.04), and after 1 month, 28.0 versus 33.5 points (<italic>p</italic> = 0.03). The advantage of the combination regimen was significant for non-acral locations and disease durations of less than 5 years. Adverse events were reported in 7 of 28 patients in the main group and 5 of 32 in the control group; all were transient and resolved spontaneously.</p> <p><bold>CONCLUSION:</bold> The combination of low-temperature argon plasma with UVB-311 nm therapy provides a significantly greater reduction in VASI and improvement in quality of life compared to monotherapy. This is a pilot, non-randomized trial with a short follow-up, which limits the validity of the conclusions and requires a randomized controlled trial.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование.</bold> Узкополосная УФБ-терапия 311 нм является методом первой линии при несегментарном витилиго, однако репигментация развивается медленно, а у части пациентов терапевтический эффект остаётся недостаточным даже при длительном лечении. Данные о применении низкотемпературной аргоновой плазмы в сочетании с фототерапией при несегментарном витилиго практически отсутствуют, тогда как взаимодополняющий характер механизмов обоих методов обосновывает целесообразность их комбинирования.</p> <p><bold>Цель исследования</bold> ― оценить эффективность и безопасность комбинированного применения низкотемпературной аргоновой плазмы и УФБ-311 нм в сравнении с монотерапией УФБ-311 нм у пациентов с несегментарным витилиго по динамике индекса площади витилиго (Vitiligo Area Severity Index, VASI) и индекса качества жизни (Vitiligo-Speciﬁc Quality of Life, VitiQoL) на протяжении 8 недель лечения и через 1 месяц по его завершении.</p> <p><bold>Методы.</bold> В проспективное нерандомизированное контролируемое сравнительное исследование включали взрослых пациентов с несегментарным витилиго при наличии депигментированных очагов, оцениваемых по VASI. Всего в исследование включено 60 пациентов. В основной группе (<italic>n</italic> = 28) медиана возраста составила 34,5 года [Q<sub>1</sub>; Q<sub>3</sub>: 26,0; 44,0], в группе сравнения (<italic>n</italic> = 32) ― 36,0 [28,0; 46,5]; женщин было 60,7% и 62,5% соответственно. Медиана длительности заболевания составила 4,5 [2,0; 9,0] и 5,0 [2,5; 10,0] лет; анамнез продолжительностью ≥ 5 лет ― у 42,9% и 50,0% участников соответственно. Группы были сопоставимы по всем исходным параметрам, статистически значимых межгрупповых различий не выявлено. Исключали пациентов с сегментарной и смешанной формами витилиго, беременных, лиц с фотодерматозами, онкологическими заболеваниями кожи, а также приёмом системных иммуносупрессантов в анамнезе. Пациенты основной группы получали воздействие низкотемпературной аргоновой плазмой на депигментированные очаги с использованием установки «Плазморан» с последующим сеансом УФБ-311 нм, группа сравнения ― монотерапию УФБ-311 нм. Лечение проводилось 3 раза в неделю в течение 8 недель. Оценка выполнялась исходно, через 4, 8 недель и 1 месяц по завершении терапии.</p> <p><bold>Результаты.</bold> В основной группе медианное значение индекса VASI снизилось с 3,8 до 2,3 балла к 8-й неделе (на 39,5%), в группе сравнения ― с 4,1 до 3,1 балла (24,4%); разница между группами составила 0,5 балла (95% ДИ 0,04–0,96; <italic>p</italic> = 0,03). Через 1 месяц различие сохранялось (2,1 против 2,9 балла, <italic>p</italic> = 0,04). По опроснику VitiQoL медианный показатель к 8-й неделе составил 30,5 против 35,0 баллов в группе сравнения (<italic>p</italic> = 0,04), через 1 месяц ― 28,0 против 33,5 (<italic>p</italic> = 0,03). Преимущество комбинированного режима было значимым при неакральной локализации и длительности заболевания менее 5 лет. Нежелательные явления, зарегистрированные у 7 (25%) пациентов основной группы и 5 (15,6%) ― группы сравнения, носили транзиторный характер и разрешались самостоятельно.</p> <p><bold>Заключение.</bold> Комбинирование низкотемпературной аргоновой плазмы с УФБ-терапией 311 нм обеспечивает статистически значимое более выраженное снижение индекса VASI и улучшение показателей качества жизни (VitiQoL) по сравнению с монотерапией. Исследование носит пилотный характер, выполнено в нерандомизированном дизайне с коротким катамнезом, что ограничивает обоснованность выводов и требует проведения рандомизированного контролируемого исследования.</p></trans-abstract><kwd-group xml:lang="en"><kwd>vitiligo</kwd><kwd>non-segmental vitiligo</kwd><kwd>low-temperature plasma</kwd><kwd>cold atmospheric plasma</kwd><kwd>ultraviolet therapy</kwd><kwd>narrowband UVB therapy</kwd><kwd>VASI</kwd><kwd>quality of life</kwd><kwd>VitiQoL</kwd><kwd>combination therapy</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>витилиго</kwd><kwd>несегментарное витилиго</kwd><kwd>низкотемпературная плазма</kwd><kwd>холодная атмосферная плазма</kwd><kwd>ультрафиолетовая терапия</kwd><kwd>узкополосная УФБ-терапия</kwd><kwd>индекс VASI</kwd><kwd>качество жизни</kwd><kwd>VitiQoL</kwd><kwd>комбинированная терапия</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Batchaeva AH, Sampiev AM, Denisenko ON.
