Mortality in Eosinophilic Esophagitis - a nationwide, population-based matched cohort study from 2005 to 2017

• Background: There is a lack of knowledge about mortality in eosinophilic esophagitis (EoE). Therefore, this study aimed to examine the mortality in EoE.Methods: A nationwide, population- based matched cohort study was conducted of all EoE patients in Sweden diagnosed between July 2005 and December 2017. Individuals with EoE (n = 1,625) were identified through prospectively recorded histopathology codes from all gastrointestinal pathology-reports in Sweden, representing 28 pathology departments (the ESPRESSO study). Each individual with EoE was then matched with up to five reference individuals from the general population (n = 8,003) for age, sex, year of birth, and place of residence. We used the Cox proportional hazard modeling to estimate the adjusted hazard ratio (aHR) and 95% confidence interval (95% CI) while adjusting for other potential confounders. In sensitivity analyses, mortality in EoE patients was compared with mortality in their siblings.Results: Through December 2017, 34 deaths were confirmed in EoE patients (4.60 per 1,000 person-years) compared with 165 in reference individuals (4.57 per 1,000 person-years). This rate corresponds to an aHR of 0.97 (95% CI = 0.67-1.40). HRs were similar in males (aHR = 1.00 [0.66-1.51]) and females (aHR = 0.92 [0.38-2.18]). We observed no increased risk in mortality due to esophageal or other gastrointestinal cancers in patients with EoE (aHR = 1.02 [0.51- 2.02]). Mortality was similar in EoE patients and their siblings (aHR = 0.91 [0.44-1.85]).Conclusion: In this nationwide, population-based matched cohort study in Sweden, there was no -increased risk of death in patients with EoE compared with their siblings and the general population.
