Abstract

Gastroesophageal reflux disease (GERD) is a common gastrointestinal disorder in cystic fibrosis (CF), and based on various studies, its prevalence is elevated since childhood. There are several pathogenetic mechanisms on the basis of association between CF and GERD. However, there are no specific guidelines for GERD in CF patients, so diagnosis is based on guidelines performed on patients not affected by CF. The aim of this review is to provide the pathophysiology, diagnostic and therapeutic options, complications, and future directions in the management of GERD patients with CF.

Keywords: Adult, Children, Cystic Fibrosis, Gastroesophageal reflux

Core Tip: Gastroesophageal reflux (GER) is common in patients with cystic fibrosis (CF) and is often regarded as playing a role in the pathogenesis of CF lung disease. Several studies have showed that patients with CF who have coexisting GER have more severe pulmonary disease with an increased numbers of infectious exacerbations as well as a lower pulmonary function. An adequate diagnostic and therapeutic management can significantly improve respiratory morbidity. Because of the lack of specific guidelines for management of GER in CF, currently, diagnosis and treatment for symptomatic GER in CF patients is based on standard guidelines for the general population. Herein, we aimed to provide a pragmatic update on the pathophysiology, diagnostic work-up, and therapeutic options in the GERD patients with CF.
