Низкое их количество в строме эндометрия, неравномерность распределения и сходство с клетками цитогенной стромы эндометрия определяют трудности их идентификации при рутинном гистологическом методе исследования, а их отсутствие ставит под сомнение диагноз ХЭ.</p><p>В работе представлены данные сравнительного ROC-анализа двух иммуногистохимических показателей хронического эндометрита: CD20+В-лимфоцитов и CD138+ плазматических клеток (ПК). В группу исследования включены 937 женщин с ХЭ, обследованные по поводу бесплодия и неудачных попыток ЭКО. Контрольную группу составили 103 женщины без признаков ХЭ, проходившие обследование по поводу мужского фактора бесплодия. Чувствительность показателя CD20+В-лимфоцитов для установления диагноза ХЭ составила 98% (Se = 0,98), что в 1,44 раза выше в сравнении с чувствительностью CD138+ ПК, соответственно, 68% (Se = 0,68). Специфичность обоих показателей для диагностики отсутствия ХЭ была высокой – 98% (Sp = 0,98) и 99% (Sp = 0,99) соответственно. Определены пороговые диагностические количественные значения двух показателей в эндометрии (точки отсечения-COP) для установления диагноза ХЭ: при использовании CD138+ПК – 1 кл/5 мм2 и CD20+В-лимфоцитов – 5 кл/5 мм2. Анализ линейной регрессии показал высоко значимую (р = 0,00053) связь CD138+ПК от CD20+В-лимфоцитов: при увеличении количества CD20+В-лимфоцитов имеет место тенденция возрастания числа CD138+ПК, что подтверждает прямую их патогенетическую связь. Установленные при иммуногистохимическом исследовании топографические и количественные особенности CD20 В-лимфоцитов в эндометрии позволяют его рекомендовать как высокочувствительный и значимый ранний диагностический показатель хронического эндометрита.</p></abstract><trans-abstract xml:lang="en"><p>Plasma cells are often considered to be among important criteria in histological diagnosis of chronic endometritis (CE). Low plasma cell numbers in endometrial stroma, uneven distribution and similarity to the cells of cytogenic endometrial stroma represent difficulties with their identification by routine histological methods of study, and their absence prevents distinct diagnosis of CE. The paper presents data on comparative ROC-analysis of two immunohistochemical parameters of chronic endometritis: CD20+B lymphocytes and CD138+ plasma cells (PC). The study group included 937 women with CE, who were examined for infertility and failed IVF attempts. The control group consisted of 103 women without signs of CE who were studied for male infertility factor.</p><p>The sensitivity of CD20+B cell assays for the diagnosis of CE was 98% (Se = 0.98), thus being 1.44 times higher compared to the sensitivity of CD138+PC, that was, respectively, 68% (Se = 0.68). The specificity of both indicators for the diagnosis of the absence of CE was high, i.e., 98% (Sp = 0.98), and 99% (Sp = 0.99), respectively. The threshold quantitative values for the two endometrial parameters (cutoff point) for the CE diagnosis were also determined when using CD138+PC-1 cell/5mm2 and CD20+B lymphocytes-5cell/5mm2. Analysis of linear regression showed a highly significant (p = 0.00053) relationship of CD138+ PC from CD20+B lymphocytes: With increased numbers of CD20+B lymphocytes, there is a trend for higher CD138+PC numbers which confirms their direct pathogenetic relationship. The topographic and quantitative features of CD20 B lymphocytes in the endometrium determined during immunohistochemical examination allow us to recommend this approach as a highly sensitive and significant early diagnostic indicator of chronic endometritis.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>хронический эндометрит</kwd><kwd>плазматические клетки</kwd><kwd>CD138</kwd><kwd>CD20</kwd><kwd>В-лимфоциты</kwd><kwd>иммуногистохимическое исследование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>chronic endometritis</kwd><kwd>plasma cells</kwd><kwd>CD138</kwd><kwd>CD20</kwd><kwd>B lymphocytes</kwd><kwd>immunohistochemical assay</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">ГОСТ Р 53022.3-2008.
