Motility Disorders Can Exist in Patients With Eosinophilic Esophagitis, Specifically in Those Not Responding to Therapy

Motility Disorders Can Exist in Patients With Eosinophilic Esophagitis, Specifically in Those Not Responding to Therapy

Eosinophilic esophagitis (EoE) is characterized by the presence of esophageal dysfunction along with histological evidence of ≥15 eosinophils per high-power field from esophageal biopsies. Recent studies have demonstrated eosinophilic infiltration of the esophageal wall in motility disorders like achalasia, although its role is not clear. The possibility of overlapping conditions like EoE and motility disorders has been entertained by several investigators.

A total of 109 patients (mean age, 37 years; 82 males) who had a new diagnosis of EoE (by upper endoscopy and biopsy) and underwent a high-resolution manometry (HRM) were included in the study. Of the 109 patients, 68 (62%) had a normal HRM, 24 (22%) had minor motor disorders, and 17 (16%) had major motor disorders (per Chicago classification). Eight patients (7.3%) had achalasia, and 8 (7.3%) had non-achalasia obstructive disorders. The group of patients with EoE and major motor disorders had more females (19 vs 8; P=.011) and responded less to topical steroids (8/16 vs 52/55; P=.005) compared to the group of patients with EoE and no motility problems. There was also a delay in diagnosis noted in the patients with EoE and achalasia (6 years) compared to the patients with EoE and without achalasia obstruction (1.5 years; P=.038).

COMMENT

From this study, it appears that about 15% of patients with EoE have coexistent major motility disorders that are diagnosed late and do not respond well to steroids. Clinicians should entertain the diagnosis of a motility disorder in patients with EoE who are difficult to treat and follow up with an HRM study.
