Sleep apnea and BE

This provocative study, while based on a chart review, suggests that persons with obstructive sleep apnea have a three-fold increased risk of BE even after controlling for obesity and reflux symptoms.

Abstract

BACKGROUND AND AIM:

Current guidelines suggest screening at-risk groups of patients for Barrett’s esophagus (BE), a precursor to esophageal cancer. Although BE and obstructive sleep apnea (OSA) have common risk factors, including elevated body mass index and gastroesophageal reflux disease (GERD), the relationship between these two conditions has not been well established.

METHODS:

Retrospectively, all patients who had undergone a polysomnography and esophagogastroduodenoscopy at West Virginia University Hospital from 2013 to 2018 were identified and divided into groups on the basis of the presence or absence of OSA. Clinical course and procedure reports were reviewed to identify relevant variables.

RESULTS:

One thousand ninety-one patients met inclusion criteria; 60.9% were female, and mean age of participants was 53.5 years. Univariate analysis revealed that male gender, age, diagnosis of OSA, severity of OSA, and a clinical diagnosis of GERD were associated with BE (P values < 0.05). Multiple logistic regression incorporating age, sex, clinical diagnosis of GERD, smoking history, body mass index, Helicobacter pylori status, and presence of hiatal hernia was utilized. Patients with OSA had an increased risk of BE than had those without OSA (P < 0.001, odds ratio 3.26 [1.72-6.85]). The risk increased with increasing severity of OSA, categorized in apnea-hypopnea index increments of 10.

CONCLUSION:

Obstructive sleep apnea is associated with BE, a relationship that is independent of other known risk factors. Additionally, this risk increases with increasing severity of OSA. Future efforts should determine if patients with severe OSA need to be screened for BE due to its potential for causing esophageal cancer.

Neoplastic progression in young Barrett's patients

Esophageal adenocarcinoma is quite rare among persons younger than 40 years, but the consequences of the disease, including years of life lost, can be devastating. Due to its rarity there has been little research on how risk factors in young persons (e.g., Barrett's esophagus (BE), obesity, GERD,

Diagnosis and management of GERD

While most adults occasionally experience symptoms of gastroesophageal reflux, such as heartburn and regurgitation, approximately 20% (30 million people in the U.S.) experience these symptoms more frequently, ranging from once a week to multiple times a day. (1) Complications associated with GERD can include esophageal strictures, ulcers, and even

Ethics of screening based on race/ethnicity

This article explores some of the ethical implications of using race and ethnicity for cancer screening, using esophageal adenocarcinoma and gastric cancer as examples. It highlights the disparities in cancer incidence and mortality among different racial and ethnic groups and examines the potential benefits and drawbacks of screening based (in

Tension between risk-based and patient-centered esophageal cancer screening

This interesting and thoughtful paper by Dr. Elspeth Davies at the University of Cambridge investigates the use of the capsule sponge test for screening Barrett's esophagus (BE) in a mobile clinic in England, highlighting the challenges in balancing patient-centered and risk-centered medical management. Through ethnographic fieldwork, the study
