For a long time, the only therapeutic option for this disease was the lifelong use of non-selective immunosuppressive agents limited by high rate of severe adverse reactions. The article presents two clinical cases of rituximab use (a targeted agent leading to B-cell depletion) in patients with pemphigus (vulgaris and foliaceous) who were previously resistant to high-dose steroid therapy. Treatment with rituximab lead to response and allowed to decrease the prednisone dose in both cases. These results confirm that rituximab can be successfully used in pemphigus as adjuvant therapy if conventional agents for this dermatosis are ineffective.</p></abstract><trans-abstract xml:lang="ru"><p>Пузырчатка представляет собой группу хронических аутоиммунных пузырных дерматозов, в основе которых лежит формирование антител к различным эпидермальным аутоантигенам. Длительное время единственной терапевтической опцией для этого заболевания было пожизненное использование неселективных иммуносупрессивных лекарственных средств, что редко сопровождалось наступлением полной ремиссии, но при этом ассоциировалось с развитием тяжелых побочных реакций. В настоящей статье представлено одно из первых в России описание применения ритуксимаба (таргетный препарат, приводящий к деплеции В-лимфоцитов) при двух вариантах истинной пузырчатки (вульгарной и листовидной), резистентных к стандартной терапии глюкокортикостероидами в сочетании с иммуносупрессивной терапией. Применение ритуксимаба в каждом случае привело к выраженному клиническому эффекту и позволило провести быстрое снижение доз системной кортикостероидной терапии до поддерживающих. Полученные результаты позволяют предположить возможность применения ритуксимаба при торпидном течении истинной пузырчатки, а также в качестве адъювантной терапии при недостаточной эффективности традиционных методов лечения этого дерматоза.</p></trans-abstract><kwd-group xml:lang="en"><kwd>pemphigus vulgaris</kwd><kwd>pemphigus foliaceous</kwd><kwd>rituximab</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>вульгарная пузырчатка</kwd><kwd>листовидная пузырчатка</kwd><kwd>ритуксимаб</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Kasperkiewicz M, Ellebrecht CT, Takahashi H, Yamagami J, Zillikens D, Payne AS, Amagai M.
