| Summary: | ABSTRACT
Objectives:
The aim of the study was to determine whether patients with eosinophilic esophagitis (EoE) have lower bone mineral density (BMD) than expected and if bone deficits are more pronounced in subgroups of patients according to comorbidities (atopic disease and joint hypermobility) or treatments (dietary restriction, medication exposure).
Study Design:
Retrospective chart review was performed to obtain clinical data, including length of diagnosis, comorbidities, and methods of treatment for patients with EoE ages 3 to 21 years who had a lumbar spine dual‐energy x‐ray absorptiometry scan performed between 2014 and 2017. BMD was standardized by calculation of age, sex, and race‐specific z scores.
Results:
A total of 269 patients met study criteria. The mean BMD z score (−0.55, 95% confidence interval: −0.68, −0.42) was lower than expected (P < 0.0001), and the prevalence of low BMD z score (≤−2.0) was higher than expected (8.5%, 95% confidence interval: 5.2%–11.9%, P < 0.0001). In multivariable regression models, BMD z scores were −0.27 lower among those following an elimination diet and −0.65 lower among those with any lifetime use of a proton pump inhibitor (93% of the sample). There was no association with swallowed steroid use.
Conclusions:
In our sample, pediatric patients with EoE had a slightly lower BMD z score compared to peers, and the prevalence of low BMD was higher than expected. Taken cautiously given the limitations of our sample, risk factors for bone deficits included any lifetime use of proton pump inhibitor and a restrictive elimination diet, but not swallowed steroid use. Larger prospective studies are needed to better characterize risk factors for low BMD to help inform screening, selection of therapies, and provide appropriate anticipatory guidance for patients with EoE. |
