Частично этот конфликт обусловлен наличием циркулирующих предсуществующих антител. Высокосенсибилизированные пациенты имеют больший риск отторжения и последующей потери трансплантата. Есть несколько методов для удаления антител, одним из которых является каскадный плазмаферез (КПФ). В настоящей работе представлен наш опыт применения КПФ у реципиентов почечного трансплантата с высоким риском развития иммунологических осложнений. </p><sec><title>Цель</title><p>Цель: провести сравнительную оценку эффективности десенсибилизации больных с высоким риском развития иммунологических осложнений посредством традиционного и каскадного плазмафереза. </p></sec><sec><title>Методы и результаты</title><p>Методы и результаты. В исследование были включены 30 пациентов после трансплантации почки. Все пациенты классифицировались как группа повышенного риска развития иммунологических осложнений. У 15 больных основной группы мы провели КПФ, у 15 пациентов из группы сравнения – традиционный плазмаферез. Мы исследовали иммунный статус: маркеры активации гуморального иммунитета – IgG, IgM, IgA до и после процедур. Процедуры КПФ проводили на аппарате OctoNova (MeSys, Германия) с плазмофильтром и сепаратором компонентов плазмы. Протокольные биопсии были выполнены на 30-й и 90-й день. Результаты исследования. Концентрация антител может быть значительно снижена при помощи КПФ. Всего концентрации IgM и IgG были уменьшены на 30–55% от исходного уровня. В случае применения КПФ отмечена значительно меньшая потеря альбумина плазмы. В основной группе был один реципиент с нарушением функции трансплантата на фоне антитело-опосредованного острого отторжения в раннем послеоперационном периоде. В то же время на протокольных биопсиях на 30-й и 90-й день не отмечено признаков отторжения, тогда как в группе сравнения было три пациента с субклиническим антитело-опосредованным отторжением. </p></sec><sec><title>Заключение</title><p>Заключение. КПФ может безопасно и эффективно снизить высокие титры антител, которые отвечают за гуморальное отторжение почечного аллотрансплантата. Снижение титра антител у сенсибилизированных больных сразу после трансплантации может улучшить функцию трансплантата.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. One of the current tasks of transplantology is to overcome «graft-host» immune confl ict. Partially this confl ict is caused by the presence of circulating pre-existing antibodies. Highly sensitized patients have a greater risk of rejection and subsequent graft loss. There are several methods to remove the antibodies, one of which is a double fi ltration plasmapheresis (DFPF). This report presents our experience of DFPF in recipients of high immunologic risk.</p></sec><sec><title>Aim</title><p>Aim: to compare the effectiveness of traditional and double filtration plasmapheresis in desensitization of patients with high risk of immunological complications.</p></sec><sec><title>Methods</title><p>Methods. The study included 30 patients after kidney transplantation. All patients were classifi ed as high-immunologic risk group. In 15 patients of study group we performed DFPF, in 15 patients of comparison group – traditional plasmapheresis. We monitored the immune status: markers of humoral immunity activation – IgG, IgM, IgA before and after the procedures. DFPF procedure was performed on OctoNova (MeSys, Germany) with a plasmafi lter and plasma components separator. Protocol biopsies were performed on days 30 and 90.</p></sec><sec><title>Results</title><p>Results. The concentration of antibodies may be effectively reduced with DFPF. Total IgM and IgG antibodies were reduced by 30–55% of the original level. There was a less albumin loss in case of DFPF application. There is 1 patient with antibody-mediated rejection with graft dysfunction in study group. There are no signs of rejection in 30- and 90-day biopsy in study group. But there were three patients with subclinical antibody-mediated rejection in the comparison group.</p></sec><sec><title>Conclusion</title><p>Conclusion. DFPF can safely and effectively reduce the high titers of antibodies that are responsible for humoral rejection of renal allograft. Reduction of antibodies in sensitized patients immediately after transplantation may improve graft function.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>аллотрансплантация трупной почки</kwd><kwd>антитела</kwd><kwd>иммуноглобулины</kwd><kwd>плазмаферез</kwd><kwd>каскадный плазмаферез</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cadaveric kidney allotransplantation</kwd><kwd>antibodies</kwd><kwd>immunoglobulins</kwd><kwd>plasmapheresis</kwd><kwd>cascade plasmapheresis</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">Naesens M., Lerut E., Sarwal M. et al.
