В данном исследовании мы изучали серопозитивность в отношении H. pylori по каждому классу иммуноглобулинов, а также их ассоциацию с полом и возрастом в выборке генеральной популяции Табриза (Иран).</p><p>В рамках этой работы обследованы 3733 участника, направленных в нашу лабораторию для тестирования в течение 2019-2022 гг. Иммуноферментная диагностика (ИФА) применялась для количественного выявления антител классов IgG, IgM и IgA к H. pylori. Статистический анализ проводили с помощью версии 20 пакета программ SPSS.</p><p>Из 3733 обследованных лиц 1235 (33,1%) были мужского пола и 2498 (66,9%) – женского. 57,9% участников имели позитивные тесты на антитела класса IgG. Для антител классов IgM и IgA к H. pylori этот показатель составил, соответственно, 0,3% и 11,6%. Средний возраст (± SD) составлял 40,72±16,91 года. Не выявлено достоверной связи между полом и позитивностью тестов по IgG и  IgA (p = 0,11 и 0,08 соответственно). При исследовании антител класса IgM показана более высокая частота позитивных тестов у женщин (0,4% среди женщин и 0,2% среди мужчин; p = 0,009). Частота встречаемости положительных тестов по IgG также достоверно возрастала (p-value &lt; 0,001). При анализе частот антител классов IgM и IgA отмечено значительное повышение числа серопозитивных лиц с возрастом (p = 0,005 и &lt; 0,001 соответственно).</p><p>Данное исследование показало, что частота выявления антител к H. pylori в Табризе составляет около 57%, что находится в пределах значений по Ирану в целом, но она выше, чем в развитых странах. Встречаемость всех классов антител против H. pylori достоверно увеличивается с возрастом.</p></abstract><trans-abstract xml:lang="en"><p>Helicobacter pylori (H. pylori) is a common infection which can lead to gastritis, peptic ulcer disease and gastric-originated malignancies. In this study prevalence of seropositivity of each immunoglobulins against H. pylori and also, their association with sex and age were evaluated in a sample of the ordinary population from Tabriz, Iran.</p><p>In this study, 3733 individuals referred to the laboratory for Para clinical tests between 2019 and 2022, participated. Enzyme-linked immunosorbent assay (ELISA) was utilized to detect the quantity of anti-H. pylori Immunoglobulin G (IgG), Immunoglobulin M (IgM), and Immunoglobulin A (IgA). The statistical analysis was conducted using the 20th version of SPSS software.</p><p>Out of 3733 participants, 1235 (33.1%) were male and 2498 (66.9%) were female. 57.9% of the participants have positive IgG serology. Also, this index was 0.3% and 11.6% for IgM and IgA, respectively. The mean (SD) age was 40.72 (16.91). There was no significant relationship between gender and IgG and IgA positiveness (p-values = 0.11 and 0.08 respectively). For IgM, serum positiveness was higher in females (0.4% for females and 0.2% for males; p-value: 0.009). The prevalence of positive IgG was increasing significantly (p-value &lt; 0.001). For IgM and IgA there was a significant increase in the number of seropositive individuals with an increase in age (p-value = 0.005; and &lt; 0.001 respectively).</p><p>This study reveals that the prevalence of H. pylori in Tabriz is approximately 57% which is in the range estimated to be in Iran, but in comparison to developed countries, it was higher. The prevalence of anti-H. pylori immunoglobulins increases significantly with age.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Helicobacter pylori</kwd><kwd>антитела</kwd><kwd>серопозитивность</kwd><kwd>Табриз</kwd><kwd>Иран</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Helicobacter pylori</kwd><kwd>Immunoglobulins</kwd><kwd>seroprevalence</kwd><kwd>Tabriz</kwd><kwd>Iran</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The authors would like to express their gratitude to the Liver and Gastrointestinal Diseases Research Center, Tabriz University of Medical Sciences, Tabriz, Iran.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Blecker U.
