US Study: Celiacs at Greater Risk of Developing Eosinophilic Esophagitis
Celiac disease (CeD) is associated with several immune-mediated disorders, but it is unclear whether it is associated with eosinophilic esophagitis (EoE).

Researchers sought to examine the risk of EoE in patients with biopsy-verified CeD compared with matched controls and siblings.
Using nationwide population-based histopathology data, they identified 27,338 patients with CeD diagnosed in the period 2002 to 2017 in Sweden.
Patients with CeD were age- and sex-matched with up to 5 reference individuals (n = 134,987) from the general population. Cox Regression was used to estimate hazard ratios (HRs) for developing biopsy-verified EoE.
In a secondary analysis, we used unaffected siblings of patients with CeD as comparators to adjust for intrafamilial confounding.
The median age at CeD diagnosis was 27 years, and 63.3% were female patients.
During a median follow-up of 8.1 years, 17 patients with CeD and 13 matched reference individuals were diagnosed with EoE.
This corresponded to incidence rates of 0.08 versus 0.01 per 1000 person-years, respectively, and an adjusted HR for EoE of 6.65 (95% CI, 3.26-13.81).
Compared with their siblings without CeD, patients with CeD were however at a no increased risk of EoE (HR, 1.39; 95% CI, 0.55-3.51).
- In this study, individuals with CeD were at a 6.6-fold increased risk of later EoE compared with the general population. This association might be explained by an altered health-seeking behavior or through shared genetic or early environmental factors because the excess risk disappeared in sibling analyses.
