Материал и методы. В проспективное исследование (2013–2014 гг.) были включены 98 больных (медиана возраста 43 года), из них 33 больных ОМЛ, 65 больных лимфомами. Период наблюдения составил 6 мес. Мазки со слизистой оболочки прямой кишки брали в первые 2 дня госпитализации, далее каждые 7 дней. Детекцию БЛРС проводили фенотипическими методами, генов резистентности blaTEM и blaCTX-M – методом ПЦР. Результаты. Всего было выделено 88 БЛРС-положительных энтеробактерий у 75 (76,5%) больных. Гены blaCTX-M были у 69% изолятов, blaTEM у 49%, оба гена у 36%. Вероятность колонизации кишечника продуцентами БЛРС у больных лимфомами составила 91%, ОМЛ – 84%. Вероятность сохранения колонизации продуцентами БЛРС составила 30,3%. У 13 (39%) из 33 больных вновь возникла колонизация БЛРС-положительными энтеробактериями с медианой в 37 дней. Вероятность возврата колонизации продуцентами БЛРС составила 49,4%. Значимыми факторами риска колонизации слизистой оболочки кишечника БЛРС-положительными бактериями были применение парентерального питания (р = 0,05) и непрерывное пребывание в стационаре (р = 0,002). Медиана непрерывного пребывания этих больных в стационаре составила 70 дней (разброс 64–180 дней). Частота бактериемии, обусловленной продуцентами БЛРС, составила 7% (у 5 из 75) у больных с колонизацией кишечника данными микроорганизмами, и не было ни одного случая у больных без колонизации. Таким образом, больные ОМЛ и лимфомами имели высокую вероятность колонизации слизистой оболочки кишечника БЛРС-положительными энтеробактериями. В течение 6 мес детекция БЛРС не была постоянной у всех больных. Колонизацию БЛРС-положительными бактериями необходимо учитывать при профилактике и выборе антибиотика у больных с фебрильной нейтропенией.</p></abstract><trans-abstract xml:lang="en"><p>The aim of this study was to determine the prevalence and risk factors of intestinal colonization with extended-spectrum beta-lactamase producing Enterobacteriaceae (ESBL-E) in patients with acute myeloid leukaemia (AML) and lymphoma. Material and methods. 98 patients (median age of 43 years; 33 – AML, 65 – lymphoma) were included in the prospective study. Follow-up period was lasted for 6 months. Rectal swabs were collected within 2 days of admission and every 7 days further. Presence of ESBL was confirmed by phenotypic tests, genes blaTEM and blaCTX-M were detected by PCR. A total of 88 ESBL-E were isolated in 75 (76.5%) patients. Results. Genes blaCTX-M were detected in 69% of isolates, blaTEM – in 49%, both genes – in 36%. Probability of intestinal colonization with ESBL-E was 91% in patients with lymphoma and 84% - in AML. Probability of persistent ESBL-E carriage was 30.3%. Recurrence of ESBL-E carriage was in 13 (39%) of 33 patients with a median of 37 days. Probability of recurrent ESBL-E colonization was 49.4%. Risk factors for ESBL-E carriage proved to be parenteral nutrition (p = 0.05) and permanent hospital stay (p = 0.002). The median of permanent hospital stay in these patients was 70 days (64–180 days). The rate of ESBL-E bacteremia in patients colonized with subsequent microorganisms was 7% (5/75). No bacteremia cases were in patients without colonization. Patients with AML and lymphoma underwent chemotherapy had a high risk of ESBL-E intestinal colonization. The presence of ESBL carriage was not permanent in all patients for 6 months. ESBL colonization should be considered in choosing antibiotics for prophylaxis and empirical approaches in patients with febrile neutropenia.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>мониторинг</kwd><kwd>колонизация</kwd><kwd>β-лактамазы расширенного спектра</kwd><kwd>БЛРС</kwd><kwd>Enterobacteriaceae</kwd><kwd>CTX-M</kwd><kwd>TEM</kwd><kwd>острые лейкозы</kwd><kwd>лимфомы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>colonization</kwd><kwd>extended-spectrum beta-lactamase</kwd><kwd>ESBL</kwd><kwd>Enterobacteriaceae</kwd><kwd>CTX-M</kwd><kwd>TEM</kwd><kwd>acute leukemia</kwd><kwd>lymphoma</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">Клясова Г.А.
