Провести типирование токсигенных штаммов Clostridium difficile, полученных от онкологических больных, находящихся в стационаре.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В исследование было включено 130 пациентов с Clostridium difficile ассоциированной диареей из хирургических и терапевтических отделений. Сначала методом иммуноферментного анализа на автоматическом анализаторе miniVidas фирмы «BioMieux SA» (Франция) определяли наличие в кале токсинов А+В+. Для скрининга с помощью метода ПЦР в реальном времени было отобрано 26 токсигенных Clostridium difficile. Для исследования использовали систему GeneXpert фирмы «Cepheid» (Швеция).</p></sec><sec><title>Результаты</title><p>Результаты. Из 1287 пациентов с диареей, проходивших лечение в стационаре НМИЦ онкологии им. Н.Н. Блохина, положительный результат на токсин А+В+ Clostridium difficile оказался у 130 пациентов (10,1%). Для исследования с помощью метода ПЦР в реальном времени было взято 26 образцов. Средний возраст больных – 57 лет. 10 (38,5%) токсигенных штаммов определили как гипервирулентный риботип. 7/10 штаммов были выделены в течение 3 последовательных месяцев. Средний возраст пациентов с гипервирулентным штаммом составил 45 лет. Пациенты, учавствовавшие в исследовании, в большинстве случаев были из хирургических отделений (61,5%), из терапевтических – 34,7%.</p></sec><sec><title>Заключение</title><p>Заключение. Исследование показало, что распространенность Clostridium difficile инфекции в нашей клинике ниже, чем в других странах. Несмотря на то, что гипервирулентные штаммы составили 1/3 от всех типированных Clostridium difficile, на них надо обратить особое внимание. Несвоевременная диагностика, запаздывание с началом специфической терапии у онкологических пациентов может привести к ухудшению качества жизни и в отдельных случаях привести к летальному исходу. ПЦР-диагностика позволяет определить гипервирулентный риботип и провести эпидемиологические мероприятия, направленные на предотвращение локальных вспышек в стационаре.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Purpose of the study</title><p>Purpose of the study. To conduct typing of toxigenic strains of Clostridium difficile, obtained from oncological patients who are in hospital.</p></sec><sec><title>Material and Methods</title><p>Material and Methods. The study included 130 patients with Clostridium difficile – associated diarrhea. First, the presence of toxins A+B+ in the feces was determined by enzyme immunoassay on an automatic miniVidas analyzer from BioMieux SA (France). For screening using real-time PCR, 26 toxigenic Clostridium difficile were selected. For the study used the system GeneXpert company «Cepheid» (Sweden).</p></sec><sec><title>Results</title><p>Results. Of the 1287 patients with diarrhea who were treated in an oncologic hospital, 130 (10,1%) tested positive for toxin A+B+ Clostridium difficile. For the study using real-time PCR, 26 samples were taken. The average age of patients is 57 years. 10 (38,5%) toxigenic strains were identified as hypervirulent ribotype. 7/10 strains were isolated for 3 consecutive month. The average age of patients with hypervirulent strains was 45 years. Patients participating in the study, in most cases were from the surgical departments – 61,5%, from the therapeutic – 34,7%.</p></sec><sec><title>Conclusion</title><p>Conclusion. The study showed that the prevalence of Clostridium difficile infection in our clinic is lower than in other countries. Although hypervirulent strains accounted for 1/3 of all typed Clostridium difficile, special attention should be paid to them. Delayed diagnosis, delay in the onset of specific therapy in cancer patients can lead to a deterioration in the quality of life and in some cases be fatal. PCR diagnostics can determine the hypervirulent ribotype and carry out epidemiological measures aimed at preventing local outbreaks in the hospital.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>Clostridium difficile</kwd><kwd>токсины А и В</kwd><kwd>бинарный токсин</kwd><kwd>гипервирулентный риботип</kwd><kwd>онкологические больные</kwd><kwd>антибиотик-ассоциированная диарея</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Clostridium difficile</kwd><kwd>toxins A and B Clostridium difficile</kwd><kwd>binary toxin</kwd><kwd>hypervirulent ribotype</kwd><kwd>cancer patients</kwd><kwd>antibiotic-associated diarrhea</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">Soto L.U., Avila S.G., Alonso A.I.C., Mesones M.P.R., Garcia A.M.A., Lamadrid M.C.V.D.
