Abstract

BACKGROUND: Obesity is associated with increased risk of gastroesophageal reflux disease (GERD).

GOAL: To evaluate the effect of obesity on symptom resolution in patients with nonerosive reflux disease (NERD) and healing rates in patients with erosive esophagitis (EE).

METHODS: Two post hoc analyses were performed. Analyses included pooled data from randomized, double-blind, multicenter studies of proton pump inhibitors (PPIs) in GERD patients.

RESULTS: Analysis 1 included 704 patients with NERD receiving esomeprazole 20 mg, esomeprazole 40 mg, or placebo. Analysis 2 included 11,027 patients with EE receiving esomeprazole 40 mg, omeprazole 20 mg, or lansoprazole 30 mg. For NERD patients, no significant association between baseline heartburn severity and body mass index (BMI) was observed. In EE patients, overweight (BMI 25 to <35 kg/m) and obese (BMI ≥35 kg/m) patients had significantly higher rates of Los Angeles (LA) grade C or D EE than patients with BMI <25 kg/m (P<0.0001). Percentages of PPI-treated patients who achieved heartburn resolution or EE healing within a given LA grade were similar across BMI categories. Heartburn resolution was significantly associated with treatment (esomeprazole vs. placebo), increasing age, and for men versus women (all P≤0.0284). EE healing was significantly associated with PPI treatment (esomeprazole and lansoprazole vs. omeprazole), increasing age, race, presence of a hiatal hernia, and lower LA grade at baseline (all P≤0.0183).…

How strong is the evidence?

Evidence Hub reads this as a meta-analysis, done in people. Its evidence level is 1 of 5 (Highest · pooled evidence). Pooled evidence from several studies sits at the top of the evidence pyramid. Reported size: 11,027 participants or records.
