Nitrates and IL-8 in Barrett's Esophagus

December 13, 2022 updated by: Cadman Leggett, Mayo Clinic

The Association Between Nitrates, Nitrosylated Proteins, and Interleukin-8 in Barrett's Esophagus and Esophageal Adenocarcinoma

The purpose of this study is to determine if nitrates and IL-8 (which are found in food and throughout the body regulating stomach acidity) play a role in Barrett's Esophagus and/or Esophageal Adenocarcinoma severity and if screening for these biomarkers can help predict patients that are more at risk for developing worsening disease.
