Образцы крови 19 реципиентов с удовлетворительной функцией трансплантата исследованы методом проточной цитофлуорометрии в различные сроки после ТП c использованием маркеров стволовых гемопоэтиеских клеток CD133, их CD31-производных и белка альфа-фетопротеина (АФП) в сравнении с конвенциальным НЛО.</p></sec><sec><title>Результаты</title><p>Результаты. Применение аналогов НЛО с CD133 и СD31 для мониторинга состояния трансплантата печени обусловлено их высоким представительством в ткани печени. Их значения изменяются в отдаленном посттрансплантационном периоде (от 1,5 до 6–7 лет после ТП) ≈20-кратно и разнонаправленно, но при условии измерения только их коммитированных к печени клеточных фракций, несущих маркер АФП.</p></sec><sec><title>Заключение</title><p>Заключение. В отличие от обычного НЛО поддержание достигнутого к 1,5 годам после ТП наименьшего уровня «аналога» НЛО CD31AFP можно считать критерием успешности иммуносупрессивной терапии в позднем периоде после трансплантации печени. Разработанная методика может быть использована для принятия решения о сокращении или прекращении медикаментозной профилактики отторжения.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective: to study the applicability of the neutrophil-to-lymphocyte ratio (NLR) for monitoring recipient status and for possible minimization of maintenance immunosuppression in the long-term period after liver transplantation (LT).</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Blood samples of 19 recipients with satisfactory graft function were examined by flow cytofluorometry at various time periods after LT using hematopoietic stem cell markers CD133, their CD31 derivatives, and alpha-fetoprotein (AFP), compared with the conventional NLR.</p></sec><sec><title>Results</title><p>Results. The use of NLR equivalents with CD133 and CD31 to assess liver transplant status is due to their high representation in liver tissue. Their values change in the long-term posttransplant period (from 1.5 to 6–7 years following LT) ≈20-fold and in different directions, but only when measuring their commissural to the liver cell fractions bearing the AFP marker.</p></sec><sec><title>Conclusion</title><p>Conclusion. In contrast to the conventional NLR, maintenance of the lowest level of CD31 AFP, an NLR «equivalent», achieved at 1.5 years after LT, can be considered a criterion for the success of immunosuppressive therapy in the long-term post-LT period. The developed technique can be used to decide on whether to reduce or discontinue medication-assisted prophylaxis of graft rejection.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>нейтрофильно-лимфоцитарное отношение</kwd><kwd>стволовые гемопоэтические клетки (СГК)</kwd><kwd>CD133</kwd><kwd>CD31</kwd><kwd>альфа-фетопротеин</kwd><kwd>трансплантация печени</kwd></kwd-group><kwd-group xml:lang="en"><kwd>neutrophil-to-lymphocyte ratio</kwd><kwd>hematopoietic stem cells (HSCs)</kwd><kwd>CD133</kwd><kwd>CD31</kwd><kwd>alphafetoprotein</kwd><kwd>liver transplantation</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">Aberg F, Gissler M, Karlsen TH, Ericzon BG, Foss A, Rasmussen A et al.
