Effect of Acid Blockade on Microbiota and Inflammation in Cystic Fibrosis (CF)
Stopped early
Conditions studied: Cystic Fibrosis
In brief
Mucus in the airways of patients with CF represents an area for bacteria proliferation, microbial infection and inflammation. Similar to the lung, the esophagus provides an environment for bacterial to grow. The overall goal of this proposal is to characterize the esophageal microbiota of children with CF that are treated or untreated with acid blockade medication and to measure its possible impact on respiratory disease to develop novel treatment strategies.
