Therefore, the search for new combined treatment regimens that reduce the dose of isotretinoin is an urgent task.</p> <p><italic>AIMS:</italic> The aim of our work was to evaluate the effectiveness of a combination of incoherent broadband light (IPL) and low doses of systemic isotretinoin (0.1–0.3 mg/kg of body weight per day) compared with monotherapy with standard doses of isotretinoin (0.5–1 mg/kg of body weight per day) in patients with acne.</p> <p><italic>MATERIAL AND METHODS:</italic> During the study, the dermatological status of patients was assessed taking into account the dermatological index GSS (Global Severity Scog), dermatological acne index (DIA), IGA scale (Investigator's Global Assessment). For a comparative analysis of the impact of various techniques on the quality of life, a high-valid quality of life index (HQIQ) was used. Dermatological status and quality of life were assessed in patients before and after 6 months of therapy. 12 months after the end of therapy, patients were invited to the clinic to identify delayed relapses.</p> <p><italic>RESULTS:</italic> Evaluating the overall results of treatment of patients with moderate severity of acne by isotretinone monotherapy and combination therapy with low doses of isotretinoin and broadband incoherent light, the effectiveness of both methods can be noted, however, according to the global severity scale (GSS), clinical remission was significantly more often observed in the combination therapy group compared with the motor therapy group (88 and 74%, respectively, <italic>p</italic> &lt;0.05). In addition, no relapses were detected after 12 months in the combination therapy group, and adverse events caused by the use of isotretionine were also less frequent.</p> <p><italic>CONCLUSION:</italic> Thus, the combination therapy of acne with low doses of isotretinoin and broadband incoherent light is more effective.</p></abstract><trans-abstract xml:lang="ru"><p>Обоснование. Длительный опыт клинического применения изотретиноина при акне свидетельствует о его хорошем профиле безопасности и эффективности, однако на фоне приёма стандартных доз препарата отмечаются выраженные нежелательные явления, которые носят дозозависимый характер. Именно поэтому поиск новых комбинированных схем лечения, позволяющих снизить дозу изотретиноина, является актуальной задачей.</p> <p>Цель исследования ― оценить эффективность комбинации некогерентного широкополосного света (IPL) и низких доз системного изотретиноина (0,1–0,3 мг/кг массы тела в сутки) по сравнению с монотерапией стандартными дозами изотретиноина (0,5–1 мг/кг массы тела в сутки) у пациентов с акне.</p> <p>Материал и методы. Дерматологический статус пациентов в ходе исследования оценивали с учётом дерматологического индекса GSS (Global Severity Sсore), дерматологического индекса акне (ДИА) и шкалы IGA (Investigator’s Global Assessment). Для сравнительного анализа влияния различных методик на качество жизни применяли высоковалидный индекс качества жизни. Дерматологический статус и качество жизни у пациентов оценивали до начала и по истечении 6 мес терапии. Спустя 12 мес пациентов приглашали в клинику с целью выявления отсроченных рецидивов.</p> <p>Результаты. Оценивая в целом результаты лечения пациентов со средней степенью тяжести акне методом монотерапии изотретиноином и комбинированной терапии низкими дозами изотретиноина и широкополосным некогерентным светом, можно отметить эффективность обоих методов, однако клиническая ремиссия по данным глобальной шкалы тяжести (GSS) достоверно чаще наблюдалась в группе комбинированной терапии по сравнению с группой мототерапии (88 и 74% соответственно, <italic>p</italic> &lt;0,05). Кроме того, в группе комбинированной терапии не выявлено рецидивов по прошествии 12 мес, а также реже наблюдались нежелательные явления, обусловленные применением изотретиноина.</p> <p>Заключение. Таким образом, комбинированная терапия акне низкими дозами изотретиноина и широкополосным некогерентным светом является наиболее эффективной.</p></trans-abstract><kwd-group xml:lang="en"><kwd>acne of moderate severity</kwd><kwd>systemic retinoids</kwd><kwd>isotretinoin monotherapy</kwd><kwd>combination therapy with low doses of isotretinoin and broadband incoherent light</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>акне средней степени тяжести</kwd><kwd>системные ретиноиды</kwd><kwd>монотерапия изотретиноином</kwd><kwd>комбинированная терапия низкими дозами изотретиноина и широкополосным некогерентным светом</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Gold MD, Baldwin H, Lin T.
