Пролиферация больших гранулярных лимфоцитов (БГЛ) может быть ассоциирована с вирусной инфекцией, аутоиммунными заболеваниями или быть проявлением хронического лимфопролиферативного заболевания NK-клеток (ХЛПЗ-NK) и Т-клеточного лейкоза из больших гранулярных лимфоцитов (T-ЛБГЛ). Дифференциальная диагностика пролиферации БГЛ до сих пор представляет определенные трудности. Цель: оценить значение иммунофенотипирования методами проточной цитометрии и ПЦР-исследования Т-клеточной клональности в разграничении реактивной и опухолевой пролиферации БГЛ. Материалы и методы. Проведен анализ основных клинико-лабораторных показателей у 68 пациентов с БГЛ -лимфоцитозом (20 мужчин и 48 женщин) в возрасте от 22 до 79 лет (медиана возраста 53 года). Всем больным было выполнено цитологическое исследование мазка периферической крови, иммунофенотипирование лимфоцитов периферической крови методом проточной цитометрии, исследование Т-клеточной клональности методом ПЦР по реаранжировкам генов γ- и β-цепей T-клеточного рецептора. Результаты. В результате исследования было показано, что морфологические и иммунофенотипические признаки, относительный и абсолютный лимфоцитоз, гетерогенность экспрессии Т-клеточных маркеров не позволяют разграничить опухолевую и реактивную пролиферацию БГЛ. Наиболее специфичным для разграничения реактивного и опухолевого БГЛ -лимфоцитоза оказалось одновременное выявление моноклональности по TCRG (V γ-J γ) и TCRG (V β-J β) локусам или выявление полной реаранжировки TCRG (V β-J β).</p></abstract><trans-abstract xml:lang="en"><p>Background. Proliferation of large granular lymphocytes (LGL) can be associated with viral infections, autoimmune disorders, chronic lymphoproliferative disorder of NK-cells (CLPD-NK), or T-cell large granular lymphocytic leukemia (T-LGL). Differential diagnosis between reactive and neoplastic LGL proliferation could be a challenge. Objective. To evaluate the role of morphological, immunophenotypic (flow cytometry) and molecular genetic (PCR-based T-cell clonality) studies in differential diagnosis of LGL proliferation. Materials and methods. 68 patients with increased peripheral blood LGL counts were enrolled in the study. Male/female ratio was 20/48; the median age was 53 (22—79) years. Blood smear, immunophenotyping by flow cytometry, and PCR-based T-cell clonality assays (TCRG (V γ-J γ) and TCRG (D β-J β and V β-J β)) were performed in all cases. Results. We found that morphology, immunophenotype, relative and absolute LGL counts, or heterogenic expression of T-cell markers can not distinguish between neoplastic and reactive LGL proliferation. Clonal TCRG (V γ-J γ) and TCRG (D β-J β) gene rearrangements were observed in reactive LGL lymphocytes and T-LGL. Complete rearrangements of TCRG (V β-J β) genes were specific for malignancies and were not detected in any case of reactive lymphocytosis.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>большие гранулярные лимфоциты</kwd><kwd>хроническое лимфопролиферативное заболевание NK-клеток</kwd><kwd>Т-клеточный лейкоз из больших гранулярных лимфоцитов</kwd><kwd>проточная цитометрия</kwd><kwd>ПЦР-исследование Т-клеточной клональности</kwd><kwd>клональные реаранжировки</kwd></kwd-group><kwd-group xml:lang="en"><kwd>large granular lymphocytes</kwd><kwd>chronic lymphoproliferative disorder of NK-cells</kwd><kwd>T-cell large granular lymphocytic leukemia</kwd><kwd>fl ow cytometry</kwd><kwd>PCR-based T-cell clonality testing</kwd><kwd>reactive lymphocytosis</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">Loughran T.
