There are assumptions that the developed chronic chlamydial infection can become an important factor in the pathogenesis of the gastrointestinal tract diseases, which are manifested in the so-called post-infectious period. It is commonly known that chlamydial infection has a tropism to the cylindrical epithelium, which covers the human mucous membrane of the urethra, cervix, rectum, conjunctiva of the eyes and the throat. However, the role of the causative agents of chlamydial infections, such as C. trachomatis and C. pneumoniae, in the occurrence of the gastrointestinal tract diseases has not been studied. In order to study the possible relationship between the gastrointestinal diseases and the presence of chlamydial infection markers, we have selected a group of patients with the gastrointestinal diseases and detected antibodies to C. trachomatis and C. pneumoniae and DNA of these pathogens in blood serum, liver biopsy and bile ducts. As a result, C. trachomatis DNA in blood serum was detected in 50% of cases, and in liver biopsies — in 59.3%. A new approach has been developed in the serological diagnosis of chlamydial infection caused by C. trachomatis, which allowed for revealing diagnostic antibody titers in 51.9% of cases in this group of patients, and in the comparison group — in 11.6% of cases. Among 50% of patients, in whom DNA was revealed in blood serum, it was also revealed in 64.3% of cases in biopsy samples of gastrointestinal organs. Upon detection of C. trachomatis DNA in blood serum, antibodies to the “cultural” antigen were detected in 60.1% of cases, and with the simultaneous detection of C. trachomatis DNA in blood serum and gastrointestinal organs, they were found in 72.2% of cases. Simultaneous detection of C. trachomatis, both in blood serum and in the gastrointestinal tract, may indicate the ability of C. trachomatis to spread hematogenously and infect organs away from the primary focus of infection. The obtained data absolutely require further study in light of the identification of the relationship between the detection of the pathogen and the development of the gastrointestinal pathology. But in general, the results are not yet studied evidence of the possible gastrointestinal organs infection by C. trachomatis.</p></abstract><trans-abstract xml:lang="ru"><p>К настоящему времени данными клинических наблюдений убедительно показано, что возбудители хламидийных инфекций, C. trachomatis и C. pneumoniae, способны вызывать серьезные заболевания с тяжелыми осложнениями и последствиями. Имеются предположения, что развившаяся хроническая хламидийная инфекция может стать важным фактором в патогенезе заболеваний желудочно-кишечного тракта (ЖКТ), которые проявляются в так называемый постинфекционный период. Как известно, хламидийная инфекция обладает тропизмом к цилиндрическому эпителию, который у человека выстилает слизистую оболочку уретры, цервикального канала, прямой кишки, конъюнктивы глаз и области глотки. Однако роль возбудителей хламидийных инфекций, таких как C. trachomatis и C. pneumoniae, в возникновении заболеваний ЖКТ человека не изучена. С целью изучения возможной взаимосвязи между заболеваниями ЖКТ и наличием маркеров хламидийной инфекции была отобрана группа больных с заболеваниями органов ЖКТ, у которых проводили выявление антител к C. trachomatis и C. pneumoniae и ДНК этих возбудителей в сыворотке крови, биоптатах печени и желчевыводящих протоков. В результате ДНК C. trachomatis в сыворотке крови была выявлена в 50% случаев, а в биоптатах печени в 59,3%. Разработан новый подход в серологической диагностике хламидийной инфекции, вызванной C. trachomatis, который позволил выявить диагностические титры антител в этой группе больных в 51,9% случаев , в группе сравнения в 11,6% случаев. Среди 50% больных, у которых ДНК была выявлена в сыворотке крови, в 64,3% случаев она также выявлялась в биоптатах органов ЖКТ. При обнаружении ДНК C. trachomatis в сыворотке крови антитела к «культуральному» антигену обнаруживались в 60,1% случаев, а при одновременном обнаружении ДНК C. trachomatis в сыворотке крови и органах ЖКТ они обнаруживались в 72,2% случаев. Одновременное выявление C. trachomatis как в сыворотке крови, так и в органах ЖКТ может свидетельствовать о способности C. trachomatis распространяться гематогенным путем и инфицировать органы, удаленные от первичного очага инфекции. Полученные данные, безусловно, требуют даль нейшего изучения в свете выявления связи между обнаружением возбудителя и развитием патологии органов ЖКТ, однако в целом результаты являются еще не изученным свидетельством возможности инфицирования C. trachomatis органов ЖКТ.</p></trans-abstract><kwd-group xml:lang="en"><kwd>C. trachomatis</kwd><kwd>C. pneumoniae</kwd><kwd>chlamydial infection</kwd><kwd>persistent infection</kwd><kwd>gastrointestinal tract</kwd><kwd>PCR</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>trachomatis</kwd><kwd>C. pneumoniae</kwd><kwd>хламидийная инфекция</kwd><kwd>персистентная инфекция</kwd><kwd>желудочно-кишечный тракт</kwd><kwd>ПЦР</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>1.
