Effects of Central Obesity on Esophageal Epithelial Barrier Function.

ABSTRACT:

Introduction

We assessed if obesity perturbs the esophageal epithelial barrier function independent of promotion of gastroesophageal reflux (GER).

Methods

Thirty-eight participants were divided into 4 groups: Obesity-/GER-, Obesity+/GER-, Obesity-/GER+, and Obesity+/GER+. Esophageal intercellular space and desmosome density (structural integrity) and fluorescein leak (functional integrity) were measured.

Results

The Obesity+/GER- group demonstrated increased intercellular space, reduced desmosome density, and increased fluorescein leak compared with control subjects. These changes were similar but not additive to findings seen in Obesity-/GER + and Obesity+/GER+ patients.

Discussion

Central obesity impairs structural and functional integrity of the esophageal b
