Однако нередки случаи изжоги, рефрактерной к антисекреторной терапии, когда не наблюдается полного купирования симптома или лишь частичный клинический эффект. Причиной неудовлетворительного ответа может являться в т. ч. функциональный генез изжоги. Целью представленного клинического наблюдения является продемонстрировать гетерогенность пациентов с изжогой, роль функциональных методов исследования в дифференциальной диагностике различных состояний, которым сопутствует данный симптом. Пациентка 42 лет поступила с целью дополнительного клинического обследования в  связи с  жалобами на  рефрактерную к  антисекреторной терапии изжогу, включившего манометрию пищевода высокого разрешения, суточную рН-импедансометрию. При манометрической оценке структуры и функции нижнего пищеводного сфинктера, а также сократительной способности грудного отдела пищевода нарушений выявлено не было. Данные суточной рН-импедансометрии продемонстрировали отсутствие патологического рефлюкса и связи активной симптоматики с эпизодами заброса желудочного содержимого в пищевод, что определило функциональный характер изжоги и  объяснило неэффективность лечения ингибиторами протонной помпы. Таким образом, изжога может носить функциональный характер и значимо снижать качество жизни пациентов. Функциональная изжога требует отличной от гастроэзофагеальной рефлюксной болезни тактики ведения, в основе чего лежит адекватная дифференциальная диагностика, включающая функциональные методы исследования, такие как манометрия пищевода высокого разрешения и суточная рН-импедансомерия, позволяющие исключить другие состояния, сопровождающиеся сходной симптоматикой. </p></abstract><trans-abstract xml:lang="en"><p>One of the main symptoms of gastroesophageal reflux disease is heartburn, for the relief of which proton pump inhibitors are traditionally prescribed. However, there are frequent cases of heartburn, refractory to antisecretory therapy, when there is no complete relief of the symptom or only a partial clinical effect. The reason for an unsatisfactory response may be the functional genesis of heartburn. The purpose of the presented clinical observation is to demonstrate the heterogeneity of patients with heartburn, the role of functional research methods in the differential diagnosis of various conditions that accompany this symptom. A 42-year-old patient was admitted for an additional clinical examination with complaints of heartburn refractory to antisecretory therapy, which included high-resolution esophageal manometry, 24-hours pH-impedance. The manometric assessment of the structure and function of the lower esophageal sphincter, as well as the contractility of the thoracic esophagus, revealed no violations. The data of 24-hours pH-impedance demonstrated the absence of pathological reflux and the association of active symptoms with refluxes, which determined the functional nature of heartburn and explained the ineffectiveness of treatment with proton pump inhibitors. Heartburn can be functional in  nature and significantly reduce the  quality of  life of  patients. Functional heartburn requires different management tactics from gastroesophageal reflux disease, which is based on an adequate differential diagnosis, including functional research methods such as high-resolution esophageal manometry and 24-hours pH-impedance measurement, which allow to exclude other conditions accompanied by similar symptoms. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>функциональная изжога</kwd><kwd>манометрия пищевода высокого разрешения</kwd><kwd>суточная рН-импедансометрия</kwd><kwd>рефлюкс</kwd><kwd>изжога</kwd><kwd>гастроэзофагеальная рефлюксная болезнь</kwd></kwd-group><kwd-group xml:lang="en"><kwd>functional heartburn</kwd><kwd>high-resolution esophageal manometry</kwd><kwd>24-hours pH-impedance</kwd><kwd>reflux</kwd><kwd>heartburn</kwd><kwd>gastroesophageal reflux disease</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">Ивашкин В.Т., Маев И.В., Трухманов А.С., Лапина Т.Л., Сторонова О.А., Зайратьянц О.В. и др.
