Those with and without a motility disorder (defined per Chicago classification CCv3.0 criteria, given the timing of the prior studies) were compared and multivariable logistic regression was used to determine odds of motility disorder by rheumatic disease. Of 289 patients, the mean age was 60.5 ± 13.8 years. Rheumatic diseases included Raynaud's (42%), rheumatoid arthritis (RA) (39%), Sjogren's (21%), systemic lupus erythematous (19%), systemic sclerosis (17%), and mixed connective tissue disease (13%). On HREM, 58% had an esophageal motility disorder: achalasia (5%), EGJ outflow obstruction (20%), jackhammer (8%), diffuse esophageal spasm (1%), ineffective esophageal motility (28%), and fragmented peristalsis (2%). Of note, 50% of the sample with a normal barium swallow had an esophageal dysmotility disorder on HREM. Those with psoriatic arthritis were less likely to have esophageal dysmotility (73% vs. 27%; P = 0.04). There was decreased odds of esophageal hypocontractility in those with RA (OR [95%CI]: 0.27 [0.12-0.58]) and increased odds (OR [95%CI]: 3.13 [1.16-8.41]) of esophageal hypocontractility among those with scleroderma.

Diagnosis is defined as symptoms of esophageal dysfunction and ≥ 15 eosinophils/high power field (HPF) in at least one of the biopsies taken from the esophagus. EoE appears to be increasing in both prevalence and incidence. The aim of this study was to investigate the prevalence, incidence, and presenting symptoms of patients with EoE within the catchment area of Northern Älvsborg County Hospital in Trollhättan. Patient records with the ICD code of EoE between 2012 and 2022 and pathology reports from esophageal biopsies from 2000-2022 were examined. Patients with symptoms of esophageal dysfunction and > 15 eosinophils/HPF were classified as having EoE.

The overall prevalence was 113 cases/100 000 inhabitants (adults 127/100 000 and children 57/100 000) at 31 December 2022. The incidence was 7/100 000 and increased during the observation period. At diagnosis, 46% of the adults and 11% of the children had a history of acute bolus obstruction requiring hospitalization, while 51% of adults and 22% of children exhibited endoscopic findings of fibrosis. The prevalence of EoE is significantly higher than that generally reported in an area of southwest Sweden. The results indicate that the incidence is increasing; however, whether this is due to an actual increase or heightened awareness of EoE is inconclusive.
