Despite they develop in childhood and young age, the issues of reproduction occurring during these pathologies virtually unexplored. The article presents a clinical case of maternal death in a 22-year-old primiparous woman and analyzes the tactics of sJIA management, which was complicated by pregnancy-related macrophage activation syndrome.</p></abstract><trans-abstract xml:lang="ru"><p>Согласно современной концепции, юношеский артрит с системным началом (системный ювенильный идиопатический артрит, сЮИА) и болезнь Стилла взрослых (БСВ) рассматриваются как редкие аутовоспалительные заболевания, в имму­нопатогенезе которых лежат объединяющие оба данных заболевания механизмы. Несмотря на развитие заболеваний в детском и молодом возрасте, вопросы репродукции при этих заболеваниях остаются практически не изученными. В статье представлен клинический случай материнской смертности 22-летней первородящей женщины, проведен анализ тактики ведения сЮИА, осложнившийся синдромом активации макрофагов во время беременности.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>системный ювенильный идиопатический артрит</kwd><kwd>сЮИА</kwd><kwd>синдром активации макрофагов</kwd><kwd>болезнь Стилла взрослых</kwd><kwd>беременность</kwd><kwd>тоцилизумаб</kwd><kwd>материнская смертность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>systemic juvenile idiopathic arthritis</kwd><kwd>sJIA</kwd><kwd>macrophage activation syndrome</kwd><kwd>adult-onset Still's disease</kwd><kwd>pregnancy</kwd><kwd>tocilizumab</kwd><kwd>maternal mortality</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">Still G.F.
