Ведущим этиологическим фактором хронического гастрита является инфекция Helicobacter pylori. Герпесвирусная инфекция может принимать участие в развитии и поддержании воспалительного процесса в слизистой оболочке желудка. Особое место среди герпесвирусов занимает вирус Эпштейна–Барр, которым инфицировано 95% населения. Целью работы было определить персистенцию вируса Эпштейна–Барр в слизистой оболочке желудка у больных хроническим Helicobacter pylori-индуцированным гастритом с эрозиями желудка и влияние на течение заболевания в зависимости от проводимой терапии. Под наблюдением находились 84 больных хроническим Helicobacter pylori-индуцированным гастритом с эрозиями желудка. У всех больных при первичном обращении кроме Нelicobacter pylori в слизистой оболочке желудка определялся вирус Эпштейна–Барр. Длительность заболевания составила от 1 до 10 лет. В зависимости от проводимой терапии пациенты с хроническим Helicobacter pylori-индуцированным гастритом с эрозиями желудка были разделены на 2 группы, между которыми через 1 год после первичного обращения проводилось сравнение частоты встречаемости вируса Эпштейна–Барр в слизистой оболочке желудка. Выявление Helicobacter pylori проводилось тремя методами: дыхательным уреазным тестом, цитологическим исследованием мазков и методом полимеразной цепной реакции биоптата. У пациентов с хроническим Helicobacter pylori-индуцированным гастритом с эрозиями желудка при выявлении герпесвирусной инфекции в слизистой оболочке желудка применение меглюмина акридонацетата в четырехкомпонентной эрадикационной терапии позволяет достоверно уменьшить количество вирусов Эпштейна–Барр. Сравнительная оценка полученных данных по наличию Helicobacter pylori в слизистой оболочке желудка у пациентов двух групп наблюдения свидетельствует о хорошем уровне эрадикационной терапии: в 1-й группе наблюдения эрадикация составила 91,3%, а во 2-й группе наблюдения – 89,5%. Микст-инфекция (Helicobacter pylori и вирус Эпштейна–Барр) в слизистой оболочке желудка является фактором, осложняющим процесс лечения пациентов. The leading etiological factor of chronic gastritis is Helicobacter pylori infection. Herpesvirus infection can take part in the development and maintenance of the inflammatory process in the gastric mucosa. A special place among herpesviruses is occupied by the Epstein–Barr virus, 95% of the population is infected with it. The aim was to determine the persistence of the Epstein–Barr virus in the gastric mucosa in patients with chronic Helicobacter pylori-induced gastritis with gastric erosions and to determine the effect on the course of the disease, depending on the therapy. 84 patients with chronic Helicobacter pylori-induced gastritis with gastric erosions were under observation. The Epstein–Barr virus was detected in the gastric mucosa in all patients at the initial treatment except for Helicobacter pylori. The duration of the disease was from 1 to 10 years. Depending on the treatment of chronic Helicobacter pylori-induced gastritis with gastric erosions, patients were divided into 2 groups, between them, 1 year after the initial treatment, the frequency of occurrence of Epstein–Barr virus in the gastric mucosa was compared. The detection of Helicobacter pylori was carried out by three methods: respiratoryurease test, cytological examination of smears and the method of polymerase chain reaction of the biopsy. In patients with chronic Helicobacter pylori-induced gastritis with gastric erosions, when detecting a herpesvirus infection in the gastric mucosa, the use of meglumine acridonacetate in four-component eradication therapy can significantly reduce the number of Epstein–Barr viruses. A comparative assessment of the data obtained on the presence of Helicobacter pylori in the gastric mucosa in patients of two observation groups indicates a good level of eradication therapy: in the 1st observation group, eradication was 91,3%, and in the 2nd observation group – 89,5%. Mixed infection (Helicobacter pylori and Epstein–Barr virus) in the gastric mucosa is a factor that complicates the treatment process of patients.

Introduction. Helicobacter pylori and Epstein–Barr virus (EBV) infection have recently been shown to be associated with gastric diseases. Polymorphisms in genes encoding cytokines such as interleukin 10 (IL-10) and interleukin 1 Receptor (IL-1RN) influence cytokine secretion levels and appear to contribute to the risk of developing gastroduodenal diseases. To our knowledge, this is the first preliminary study to address the association of coinfection with H. pylori and EBV and their correlation with genetic predisposition in the development of gastric diseases. Methods. Gastric biopsy samples of 96 patients with different gastric diseases were used. Results. Our results showed that the rate of coinfection was higher in patients with gastric cancer than in patients with normal gastric mucosa, active chronic gastritis, and MALT lymphoma. As regards the characterization of H. pilory strains, the polymorphism s1m1i1 of vacA gene was more frequent in patients with MALT Lymphoma in comparison to others, while the polymorphism s2m2i2 was most frequent in patients with normal gastric mucosa. In addition, patients who tested positive for the cagA gene were more frequently those affected with gastric cancer than those with inactive chronic gastritis. Similarly, the patients with oipA gene ON were more frequently those with gastric cancer than those with inactive chronic gastritis. Conclusion. According to our analysis, there was no correlation between coinfection and polymorphisms in genes encoding IL-10 and IL-1RN. We conclude that various factors can be involved in the development of gastric diseases.

Аim. To study the severity of chronic erosive gastritis associated with Helicobacter pylori and Epstein-Barr virus depending on the number of copies of Epstein-Barr virus in biopsies of gastric mucosa. Materials and methods. The severity of chronic erosive gastritis associated with Helicobacter pylori in the presence and absence of Epstein-Barr virus in the gastric mucosa was compared in 65 patients, divided into 4 groups depending on the detection of Epstein-Barr virus in the gastric mucosa. Result. the presence of Epstein-Barr virus in the gastric mucosa aggravates the course of chronic erosive gastritis associated with Helicobacter pylori.

High prevalence of infection with Epstein-Barr virus (EBV) andpotentially oncogenic Helicobacter pylori requires understanding their role in pre-cancerous and cancerous processes. We studied peculiarities of humoral immunity against Epstein-Barr virus and the severity of viral infestation in patients with stomach dysplasia, cancer and concomitant infection of gastric mucosa with H.pylori. It was shown that the development of dysplastic changes in the infected mucosa is most frequently associated with high titers of IgG and IgA to capsid antigen and early EBV antigens which suggests their cooperation in the development ofprecancerous disorders. The character of antiviral humoral reactions in cancer patients depends on viral infestation of the neoplastic tissue. ECB and H.pylori infections are mutually exclusive in such patients. The absence of H.pylori is associated with the high level of antiviral humoral reactions and high infestation of the neoplastic tissue with EBV whereas low levels of antiviral humoral reactions occur in patients with H.pylori infection.
