Цель исследования: оценить прогностическую значимость биомаркеров атрофии в развитии РЖ в популяционной выборке лиц европеоидного происхождения в проспективном исследовании «случай-контроль». Материалы и методы исследования: случаи РЖ и контроля подобраны из популяционной выборки жителей Новосибирска в рамках международного проекта HAPIEE в период 2003-2005 гг. с включением лиц обоего пола (n=9360) в возрасте 45-69 лет. Образцы сыворотки хранились при -700С. Случаи РЖ полученные из популяционного регистра РЖ до 2012 г. были сопоставлены с базой данных HAPIEE с подбором соответствующего по возрасту и полу контроля в соотношении 1:2. В итоге, 156 образцов сыворотки крови (52 - РЖ, 104 - контроль) были проанализированы с помощью панели биомаркеров. В оценке биомаркеров атрофического гастрита использовали пороговые значения, рекомендуемые производителем: для пепсиногена I (ПГI) &lt;30 мкг/л, для пепсиногена II (ПГII) &lt;3 мкг/л, для соотношения ПГI/ПГII &lt;3, для гастрина-17 &lt;1 пмоль/л. Результаты: средние показатели ПГI и соотношения ПГI/ПГII оказались достоверно ниже в группе с РЖ по сравнению с контролем (р=0,005 и р=0,0001, соответственно), в отношении других биомаркеров различий не найдено. В ROC-анализе пороговые значения (Сut-off) показателей атрофии для риска РЖ оказались выше нормативных: для ПГI - 55 мкг/л (р=0,0001; OR=4,1; 95 % CI 2,0-8,4); для соотношения ПГI/ПГII - 5 (р=0,0001; OR =5,8; 95 % CI 2,7-12,4). В однофакторном анализе прогностически значимыми оказались низкие уровни ПГI и соотношения ПГI/ПГII. Многофакторный регрессионный кондициональный анализа с учетом возраста, пола и всех показателей тест системы значимым показал только низкий уровень соотношения ПГI/ПГII (OR=2,9; 95 % CI=1,01-8,0). Выводы: Проспективное исследование «случай-контроль» (с 8-летней глубиной проспекции) показало, что низкие показатели ПГI и соотношения ПГI/ПГII являются прогностически значимыми в отношении риска рака желудка в европеоидной Западно-Сибирской популяции.</p></abstract><trans-abstract xml:lang="en"><p>Background: atrophic gastritis (AG) associated with Helicobacter pylori (H. pylori-infection) is one of the precancerous lesions and associated with low level of serum pepsinogen I (PGI) and PGI/PGII ratio, which are also recognized like predictive markers for gastric cancer (GC) development. The aim of the study: to analyze the predictive value of biomarkers in the GC development in a prospective “case-control” study conducted in Caucasian population of Western Siberia (8 years follow-up). Material and Methods: GC cases and control were selected from population cohort of residents of Novosibirsk within the international HAPIEE project during 2003-2005 with inclusion of subjects (n=9360) of both sexes at the age of 45-69 years. Serum samples were stored at -700С. GC cases received from Population Cancer Registry until 2012 were compared with the database of HAPIEE with selection of appropriate on sex and age control in the ratio 1:2. Finally, 156 serum samples (52 - the main group and 104 - control) were available for analysis, and biomarkers were measured. The following criteria for biomarkers of atrophic gastritis were used: PGI &lt; 30 µg/l, PGII &lt; 3 µg/l, PGI/PGII &lt; 3, G-17 &lt; 1 pmol/l. Results: The mean levels of PGI and PgI/PgII ratio in the GC group was lower in comparison with the control (p &lt; 0.005 and p&lt; 0.0001, respectively); no difference was shown in respect to the other biomarkers. The cut-off values of atrophy have appeared above the recommended parameters: for PGI-55 µg/l (р=0.0001; OR=4.1; 95 % CI 2.0-8.4) and PGI/PGII ratio-5 (р=0.0001; OR =5.8; 95 % CI 2.7-12.4). Conditional (fixed effects) logistic regression analysis with inclusion into the model sex, age of the patients, and all biomarkers of test system showed PGI/PGII ratio as the most powerful indicator in the model (OR=2.9; 95 % CI: 1.0-8.0). Conclusions: for the first time the predictive value of low indicators of PGI and PGI/PGII ratio in GC risk development in Caucasian population for 8 years follow-up was demonstrated.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>атрофический гастрит</kwd><kwd>рак желудка</kwd><kwd>пепсиногены</kwd><kwd>европеоиды</kwd></kwd-group><kwd-group xml:lang="en"><kwd>H. pylori</kwd><kwd>atrophic gastritis</kwd><kwd>gastric cancer</kwd><kwd>pepsinogens</kwd><kwd>H. pylori</kwd><kwd>Caucasians</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">Melton S.
