В инструкции к препарату дупилумаб указано, что введение однократной нагрузочной дозы в первый день приводит к быстрому достижению клинически эффективных концентраций в течение 2 недель, что мы и увидели на примере нашей пациентки и ее реального клинического ответа на введение уже первой инъекции.</p><p>   Изложение клинического случая. Под нашим медицинским наблюдением находилась пациентка 17 лет с тяжелым течением атопического дерматита, резистентного к традиционной терапии. Наследственность по аллергической патологии отягощена: мать девочки страдает пыльцевой аллергией. Исходно до начала терапии: SCORAD — 88 баллов, EASI — 48,8 балла, IGA — 4, эозинофилы крови — 11 % (1188 кл/мл), общий IgE — 1102,0 МЕ/мл; содержание оксида азота в выдыхаемом воздухе (FеNO) — 30 ppb. 28. 04. 2021 больной введен дупилумаб в дозе 600 мг. Оценка контроля атопического дерматита в баллах при поступлении в стационар через 2 недели после первого введения дупилумаба: по шкале SCORAD — 44,5 балла; EASI — 13,8 балла; IGA — 2 балла, эозинофилы — 9 % (1070 клеток/мл); общий IgE — 840 МЕ/мл; FeNO — 5 ppb.</p></sec><sec><title>   Заключение</title><p>   Заключение. Данное клиническое наблюдение наглядно иллюстрирует тот факт, что пациенты с тяжелой степенью атопического дерматита, не отвечающие положительным эффектом на первые линии терапии, могут достичь положительных клинических результатов уже после первого применения рекомбинантного человеческого моноклонального антитела (IgG4).</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>   Introduction</title><p>   Introduction. The instructions for the drug dupilumab indicate that the administration of a single loading dose on the first day leads to the rapid achievement of clinically effective concentrations within 2 weeks, which we saw in the example of our patient and her real clinical response to the first injection.</p><p>   Presentation of a clinical case. Under our medical supervision was a 17-year-old patient with severe atopic dermatitis, resistant to traditional therapy. Heredity for allergic pathology is burdened: the girl’s mother suffers from pollen allergy. Initially before the start of therapy: SCORAD — 88 points, EASI — 48.8 points, IGA — 4, blood eosinophils — 11 % (1188 cells/ml), total IgE — 1102.0 IU/ml; the content of nitric oxide in exhaled air (FeNO) is 30 ppb. On April 28, 2021, the patient was administered dupilumab at a dose of 600 mg. Assessment of atopic dermatitis control in points upon admission to the hospital 2 weeks after the first administration of dupilumab: on the SCORAD scale — 44.5 points; EASI — 13.8 points; IGA — 2 points, eosinophils — 9 % (1070 cells/ml); total IgE — 840 IU/ml; FeNO — 5 ppb.</p></sec><sec><title>   Conclusion</title><p>   Conclusion. This clinical observation clearly illustrates the fact that patients with severe atopic dermatitis who don’t respond to first-line therapy can achieve positive clinical results after the first use of a recombinant human monoclonal antibody (IgG4).</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>атопический дерматит</kwd><kwd>биотерапия</kwd><kwd>дупилумаб</kwd></kwd-group><kwd-group xml:lang="en"><kwd>atopic dermatitis</kwd><kwd>biotherapy</kwd><kwd>dupilumab</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Клинические рекомендации.
