Achalasia Frequent in Patients with Eosinophilic Esophagitis

M Ghisa et al. Clin Gastroenterol Hepatol 2021; 19: 1554-1563. Achalasia and Obstructive Motor Disorders Are Not Uncommon in Patients With Eosinophilic Esophagitis

In this study with 109 adults who were newly diagnosed with eosinophilic esophagitis (EoE), the authors consecutively performed high-resolution manometry (HRM). Key findings:

  • 68 (62%) had normal findings from HRM
  • 8 (7.3%) had achalasia (1 with type 1, 4 with type 2, and 3 with type 3)
  • 9 (8.3%) had major motor disorders of esophagus (& not achalasia) and 24 (15.6%) had minor motor disorders

These findings are important because the diagnosis of EoE could result in a diagnostic delay of concurring achalasia and because the presence of esophageal eosinophilia could perhaps play a role in the pathogenesis of achalasia (or vice versa). The finding of achalasia in 7.3% of this population is exponentially higher than the estimated prevalence of achalasia in the general population (10-16 cases per 100,000).

My take: In patients with EoE, further diagnostic workup is indicated if there are persistent symptoms.
