Многофакторность возникновения и этапность воспалительных изменений в слизистой оболочке желудка определяют необходимость поиска условий, способных влиять на замедление прогрессирования гастрита у детей.</p></sec><sec><title>Цель</title><p>Цель: определить проявления Helicobacter pylori-ассоциированного антрального гастрита у подростков с гиповитаминозом D.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. Обследовано 93 подростка в возрасте 12–17 лет с диагнозом «гастрит». Методом иммуноферментного анализа определено содержание витамина D в крови. Подростки распределены на группы в зависимости от уровня обеспеченности витамином D и от периода солнечной инсоляции.</p></sec><sec><title>Результаты</title><p>Результаты. Инфицированность H. pylori подростков с гиповитаминозом D имела выраженную тенденцию к увеличению — 75% (53,6% у детей с достаточным уровнем витамина D; р = 0,067). Частота H. pylori среди подростков, обследованных при низкой солнечной инсоляции, была выше, чем в период высокой солнечной инсоляции (р = 0,015). В период низкой солнечной инсоляции выявлены высокие показатели инфицирования H. pylori среди подростков с недостатком витамина D (88,2% в сравнении с 62,1% в контроле; р = 0,057). В период высокой инсоляции инфицированность H. pylori была примерно одинаковой (р = 0,82). Антральный гастрит с высокой активностью определялся у инфицированных H. pylori подростков, и его частота не зависела от уровня витамина D в крови.</p></sec><sec><title>Заключение</title><p>Заключение. Гиповитаминоз D связан с H. pylori-ассоциированным гастритом, имеющим высокую активность воспалительного процесса и зависимость от интенсивности солнечной инсоляции.</p></sec><sec><title>Участие авторов</title><p>Участие авторов:Аникина К.А., Поливанова Т.В. — концепция и дизайн исследования;Аникина К.А., Вшивков В.А. — сбор и обработка материала;Аникина К.А. — статистическая обработка, написание текста;Поливанова Т.В., Вшивков В.А. — редактирование.Все соавторы — утверждение окончательного варианта статьи, ответственность за целостность всех частей статьи.</p></sec><sec><title>Финансирование</title><p>Финансирование.

The multifactorial nature of the occurrence and phasing of inflammatory changes in the gastric mucosa determine the need to search for conditions that can affect the slowing of the progression of gastritis in children.</p></sec><sec><title>Aim</title><p>Aim: to determine the manifestations of Helicobacter pylori-associated antrum gastritis in adolescents with hypovitaminosis D.</p></sec><sec><title>Material and methods</title><p>Material and methods. Ninety three 12–17 years adolescents with a morphologically confirmed diagnosis of gastritis were exa­mined. The content of vitamin D in the blood was determined using the ELISA method. Adolescents were divided into groups depending on the level of vitamin D supply and the period of solar insolation at the time of the examination.</p></sec><sec><title>Results</title><p>Results. H. pylori infection in adolescents with hypovitaminosis D had a pronounced tendency to increase — 75% (53.6% in child­ren with sufficient vitamin D levels; p = 0.067).</p></sec><sec><title>The frequency of H</title><p>The frequency of H. pylori among adolescents examined during low solar insolation was higher than during high solar insolation (p = 0.015). During the period of low solar insolation, the highest rates of H. pylori infection in children were found among adolescents with vitamin D deficiency (88.2% compared to 62.1% among children with a normal vitamin D supply; p = 0.057). During the period of high insolation, H. pylori infection was approximately the same (p = 0.82).</p><p>Antral gastritis with high activity was predominantly detected in adolescents infected with H. pylori and its frequency did not depend on the level of vitamin D in the blood.</p></sec><sec><title>Conclusion</title><p>Conclusion. Hypovitaminosis D is associated with H. pylori-associated gastritis, characterized by greater activity of the inflammatory process and has a clear relationship with the intensity of solar insolation.</p></sec><sec><title>Contribution</title><p>Contribution: Anikina K.A., Polivanova T.V. — concept and design of the study;Anikina K.A., Vshivkov V.A. — data collection and processing;Anikina K.A. — statistical processing of the data, writing the text;Polivanova T.V., Vshivkov V.A. — editing the text.All co-authors — approval of the final version of the article, responsibility for the integrity of all parts of the article.</p></sec><sec><title>Acknowledgment</title><p>Acknowledgment.
