Helicobacter pylori (Hр) — спиралевидная бактерия, эволюционно приспособленная к существованию в надэпителиальной желудочной слизи. Рассматривается в настоящее время как один из факторов развития гастрита, язвенной болезни и злокачественных новообразований желудка, хотя неоднократно высказывались и противоположные мнения. Целью данного исследования является оценка содержания сывороточных антител к Нр и рекомбинантному антигену CagA в выборке трудоспособных жителей Москвы. </p></sec><sec><title>Материал и методы</title><p>Материал и методы. Обследованная выборка жителей Москвы включала 319 чел. обоего пола трудоспособного возраста. Для измерения содержания сывороточных антител к Нр и CagA использовались тест-наборы ИФА-Хеликобактер IgG (ЗАО «ЭКОлаб») и «ХеликоБест — антитела» (ЗАО «Вектор-Бест») соответственно. </p></sec><sec><title>Результаты</title><p>Результаты. Показано, что положительную реакцию на наличие IgG-антител к H. pylori имело 85% обследованных лиц с близким к логнормальному распределением титров антител (медиана 1:688; Q1–Q3 1:370–1:1223) при значении уровня среза 1:100. По уровню суммарных антител (IgM, IgA и IgG) к антигену CagA серопозитивными являлись 54% обследованных лиц с содержанием антител в условных единицах ИФА (EU, elisa units) от 23 до 129 (медиана 87,9; Q1–Q3 56,7–102,5) при значении уровня среза 18,5; распределение этой величины резко отличалось от логнормального распределения содержания IgG-антител к комплексу антигенов Hр и имело признаки бимодальности со сдвинутым вправо основным максимумом. В полной выборке обследованных лиц (N = 319) содержание сывороточных антител к Нр и CagA было связано слабой (R = 0,217), но высокодостоверной (p = 0,00009) положительной связью; в зоне выше уровней среза обеих переменных достоверная связь между ними отсутствовала. </p></sec><sec><title>Обсуждение</title><p>Обсуждение. Обсуждены возможные причины различий в характере распределения изучавшихся показателей. Логнормальное распределение содержания антител к комплексному антигену Нр с учётом экстраординарной генетической вариабельности природных изолятов может отражать комбинаторные различия в степени близости антигенных детерминат Нр у конкретного человека с представленными в антигенном препарате. Возможно, бимодальное распределение содержания антител к индивидуальному антигену CagA отражает генетически детерминированные различия по иммунореактивности внутри обследуемой популяции людей.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Helicobacter pylori (Hр) is a helix-shaped bacterium adapted evolutionary to living in the mucoid of stomach. Considered usually as one of the factors in the development of gastritis, peptic ulcer and gastric cancer, but the opposite opinions were also discussed. The aim of this study was to assess levels of serum antibodies to Hp and recombinant CagA in the cohort of working-age Moscow adults. </p></sec><sec><title>Methods</title><p>Methods. Commercial ELISA kits “IFA-Helicobacter IgG”© (ZAO EKOlab, Russia) and “HelicoBest-antibodies”© (ZAO Vector-Best, Russia) were applied for the estimation of serum antibodies to Hp and CagA, correspondingly, in the observed cohort (both gender adults, N=319). </p></sec><sec><title>Results</title><p>Results. 85 % of the human cohort (N=271) had positive rates of IgG-antibodies against complex Hp antigen, with lognormal distribution of IgG titers (median 1:688; Q1 — Q3 1:370 - 1:1223) and cut-off value equal to 1:100. 54 % of the human cohort (N=172) were seropositive to recombinant CagA, with the levels of total serum antibodies (IgM, IgA and IgG) from 23 to 129 elisa units (median 87,9; Q1 — Q3 56,7 — 102,5) and cut-off value equal to 18,5 EU. The distribution of CagA antibody levels was sharply different from lognormal distribution of IgG titers to complex Hp antigen and had signs of bimodality with the main maximum shifted to the right. In the complete cohort under observation (N=319), the levels of serum antibodies to Hp and CagA were associated with a weak (R=0,217), but highly significant (p=0,00009) positive linkage; human persons, seropositive to both antigens, had no any association between the markers. </p></sec><sec><title>Discussion</title><p>Discussion. Possible reasons of differences in the shape of distributions of the studied markers are discussed. Taking into account the extraordinary genetic variability of natural Hp isolates, lognormal distribution of antibodies to complex Hp antigen can reflect combinatorial differences in the degree of proximity of Hp antigenic determinants between human persons under observation and the antigenic preparation. Bimodal distribution of antibody levels to individual protein CagA, possibly, reflect genetically determined differences in immunoreactivity inside the observed cohort.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>трудоспособное население</kwd><kwd>сыворотка крови</kwd><kwd>иммуноферментный анализ</kwd><kwd>уровень антител</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Helicobacter pylori</kwd><kwd>рекомбинантный антиген CagA</kwd><kwd>human cohort</kwd><kwd>Moscow adults</kwd><kwd>blood serum</kwd><kwd>ELISA</kwd><kwd>antibodies</kwd><kwd>Helicobacter pylori</kwd><kwd>recombinant CagA</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">Blaser M.J.
