Seasonal variation has been reported in diagnosis of eosinophilic esophagitis (EoE), but results are not consistent across studies and there are no national-level data in the United States. To determine if there is seasonal variation in diagnosis of esophageal eosinophilia and EoE in the U.S., while accounting for factors such as climate zone and geographic variation. This was a cross-sectional study using a U.S. national pathology database. Patients with esophageal eosinophilia (≥15 eosinophils per high-power field) comprised the primary case definition and were compared to those with normal esophageal biopsies. We calculated the crude and adjusted odds of esophageal eosinophilia by season, as well as by day of the year. Sensitivity analyses were performed using more restrictive case definitions of EoE, and after stratification by climate zone. 14,524 cases with esophageal eosinophilia and 90,459 normal controls were analyzed. The adjusted odds of esophageal eosinophilia were higher in the late spring and summer months, with the highest odds in July (aOR 1.13; 95%CI: 1.03–1.24). These findings persisted with increasing levels of esophageal eosinophilia, as well as across EoE case definitions. Seasonal variation was strongest in temperate and cold climates, and peak diagnosis varied by climate zone. There is a mild but consistent seasonal variation in the diagnosis of esophageal eosinophilia and EoE, with cases more frequently diagnosed during summer months. These findings take into account climate and geographic differences, suggesting that aeroallergens may contribute to disease development or flare.
