Lack of timely treatment can lead to death. Due to the fact that in the Russian Federation the main method of treatment for CAP is the prescription of systemic glucocorticosteroid drugs, which cause a large number of side effects, studies confirming the effectiveness and safety of the use of rituximab in combination with systemic glucocorticosteroid (GCS) are of particular interest. Rituximab is a genetically engineered monoclonal antibody to the CD20 antigen. The mechanism of action is due to the binding of the antibody to the CD20 antigen on B-lymphocytes and the initiation of immunological reactions that mediate the lysis of B-cells, that leads to the elimination of circulating desmoglein-specific IgG(+) B-lymphocytes and contributes to the high effectiveness of rituximab in the treatment of pemphigus. In the treatment PV including rituximab and systemic corticosteroids there is a chance of possible faster reduction of corticosteroids in the daily dose, followed by their complete withdrawal after 3–6 months, that reduces the risk of serious complications developing.</p></abstract><trans-abstract xml:lang="ru"><p>Вульгарная пузырчатка (ВП) — это аутоиммунное заболевание, поражающее слизистые оболочки и/или кожу, которое характеризуется образованием пузырей различных размеров с тонкой, вялой покрышкой и серозным содержимым. Отсутствие своевременного лечения может привести к летальному исходу. В связи с тем, что в Российской Федерации основным методом терапии ВП является назначение системных глюкокортикостероидных препаратов, вызывающих большое число побочных эффектов, особый интерес вызывают исследования, подтверждающие эффективность и безопасность применения ритуксимаба в комбинации с системными глюкокортикостероидами (ГКС). Ритуксимаб — генно-инженерное моноклональное антитело к антигену CD20. Механизм действия обусловлен связыванием антитела с антигеном CD20 на В-лимфоцитах и инициацией иммунологических реакций, опосредующих лизис В-клеток, что приводит к элиминации циркулирующих десмоглеин-специфичных IgG(+) В-лимфоцитов и способствует высокой эффективности ритуксимаба в лечении пузырчатки. При терапии пациентов с ВП ритуксимабом и системными ГКС возможно более быстрое снижение суточной дозы ГКС с их последующей полной отменой через 3–6 месяцев, что уменьшает риск развития серьезных осложнений.</p></trans-abstract><kwd-group xml:lang="en"><kwd>pemphigus vulgaris</kwd><kwd>rituximab</kwd><kwd>bubble</kwd><kwd>IgG</kwd><kwd>glucocorticosteroids</kwd><kwd>case report</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>вульгарная пузырчатка</kwd><kwd>ритуксимаб</kwd><kwd>пузырь</kwd><kwd>IgG</kwd><kwd>глюкокортикостероидные препараты</kwd><kwd>клинический случай</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Kridin K, Sagi SZ, Bergman R.
