Functional dyspepsia and duodenal eosinophilia: A new model

Abstract: Functional dyspepsia (FD) is a highly prevalent disorder that affects more than 10% of the population. In the past decade, the theoretical underpinning of the concept of FD has begun to change, in light of new data on the underlying pathophysiological mechanisms of this disorder, with a focus on the duodenum. The Rome IV criteria, published in 2016, note that gastroesophageal reflux disease and irritable bowel syndrome overlap with FD more than expected by chance, suggesting that they may be part of the same d… Show more

“…There has also been a recently demonstrated association between FD and both duodenal eosinophilia [4,5], and duodenal eosinophil degranulation [6]. An evolving paradigm posits that the recruitment of excess eosinophils (possibly in response to prior infection or allergen exposure) leads to degranulation and local nerve damage, predisposing patients to pain, increased mucosal permeability, and altered motility [7].…”

“…While underreported, such structural change could account for the modest, though significant effect seen with rebamipide. Second, cytokine release due to eosinophil degranulation may mediate both gastroduodenal dysfunction and extra intestinal effects (including central symptoms, such as anxiety) in patients with FD [7]. Rebamipide-related impairment of inflammation due to cytokine release may constrain this sequence of events, thereby providing symptom relief.…”

“…Важную роль в патогенезе ФД отводят изменениям именно двенадцатиперстной кишки [19]. У большинства пациентов с ФД выявляются микроскопические признаки воспаления слизистой постбульбарного отдела двенадца-типерстной кишки -повышенное содержание интраэпите-лиальных лимфоцитов (преимущественно CD8+), эозино-филов и иногда -базофилов, а также признаки повышен-ной проницаемости слизистой оболочки и системной вос-палительной активности [19,20].…”

Развитие микроскопиче-ского воспаления может быть связано с перенесенной пищевой токсикоинфекцией [21], повторными воздействи-ями раздражителей, а также хеликобактерной инфекцией (в последнем случае более корректно, как уже говорилось выше, применять термин «диспепсия, ассоциированная с инфекцией H. pylori») [22].…”
