Core Tip

Core tip: The present study aimed to explore the mechanisms involved in the pathogenesis of gastroesophageal reflux disease (GERD) symptoms and complications, which remain to be fully elucidated. Despite recent evidence confirming the important production of inflammatory mediators and neurotransmitters in the pathogenesis of GERD, the interplay between esophageal inflammation and hypersensitivity is not clear. Based on the literature and on personal experimental studies, this paper attempts to summarize the evidence concerning the inflammatory pathway involved in GERD pathogenesis, to better define the possible distinction between erosive and non-erosive reflux disease patients and to provide new therapeutic approaches.
