До недавнего времени единственным методом лечения этой болезни оставалось раннее интенсивное проведение плазмафереза, которое, тем не менее, во многих случаях оказывалось недостаточно эффективным и не предотвращало ишемических повреждений различных органов. Экулизумаб, ингибитор активации комплемента по альтернативному пути, вызывает быстрое и устойчивое подавление тромботической микроангиопатии (ТМА) при аГУС, значительно улучшая исход и прогноз этого заболевания. Общепризнанный терапевтический эффект экулизумаба в настоящее время сделал его препаратом первой линии в тех случаях, когда, после исключения всех других возможных причин ТМА, диагноз аГУС становится несомненным. Мы представляем собственное наблюдение за 13-летним мальчиком с установленным ранее диагнозом аГУС, у которого экулизумаб был применён из-за персистирующих неспецифических клинических проявлений при отсутствии лабораторных признаков активности тромботической микроангиопатии (нормальные показатели тромбоцитов и ЛДГ, отсутствие шизоцитов). Это лечение привело к купированию протеинурии и анемии, значительному улучшению самочувствия и увеличению СКФ, что заставило нас предположить субклиническую активность болезни.</p></abstract><trans-abstract xml:lang="en"><p>Atypical hemolytic uremic syndrome (aHUS) is a rare, life-threatening disease related to uncontrolled complement activation. Until recently, the management of aHUS consisted of early and intensive plasma exchange, although this was mostly ineffective in protecting from subsequent organ damage. Eculizumab, an inhibitor of the alternative complement pathway, produces a rapid and sustained inhibition of the thrombotic microangiopathy process, with significant improvements in long-term clinical outcomes. Due to the significant improvement achieved, eculizumab has subsequently been approved as the first-line therapy when an unequivocal diagnosis of aHUS has been made. The use of eculizumab has changed the management and the outcome of aHUS, becoming the frontline treatment of the disease. We report a case of a 13 year-old boy with aHUS who got eculizumab because of persistent non-specific clinical symptoms in the absence of laboratory evidence of active thrombotic microangiopathy. The use of eculizumab was associated with a significant decrease in proteinuria, anemia, increased GFR and an improvement in general state, revealing that the subclinical symptoms were caused by unsuspected disease activity.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>гемолитико-уремический синдром</kwd><kwd>протеинурия</kwd><kwd>экулизумаб</kwd><kwd>hemolitic uremic syndrome</kwd><kwd>proteinuria</kwd><kwd>eculizumab</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">Байко С.В.
