Abstract
- Ethnic differences in achalasia presentations have scarcely been described. The association between achalasia and immunologic HLA haplotypes suggests that there may be a genetic predisposition. We aimed to evaluate differences in demographic, clinical, endoscopic, and manometric findings between two distinct ethnic groups with achalasia-Israeli Arabs (IA) and Israeli Jews (IJ).A retrospective study was performed at two medical centers. High-resolution manometry (HRM) reports were reviewed for newly-diagnosed achalasia patients. Demographic data, clinical presentations, endoscopy reports, and HRM metrics including the integrated relaxation pressure (IRP) were all reviewed.Overall, 94 achalasia patients were included (53.2% male; mean age 54.5 ± 18.0). 43 patients were IA (45.7%). Body mass index (BMI) was similar in both groups. Compared to IJ, the IA patients had more esophageal dysphagia (100% vs. 88.2%; P = 0.022), chest pain (46.5% vs. 25.5%; P = 0.033), and a tortuous esophagus on endoscopy (23.3% vs. 3.9%; p = 0.005). IA patients were also diagnosed at a younger age than IJ patients (50.9 ± 17.5 vs. 57.5 ± 18.0; p = 0.039). Furthermore, IRP values were higher among IA patients than IJ patients (32.2 ± 13.8 vs. 23.3 ± 8.4; p 0.001). A regression model analysis found that ethnicity significantly predicted IRP (β = - 10, p .001).Ethnicity appears to affect achalasia clinical presentation and HRM findings. IA achalasia patients are diagnosed at a younger age, present with more severe esophageal symptoms, and have a higher IRP compared to IJ patients. Additional studies of diverse, multiethnic populations, especially with genetic evaluations, are required to further assess the role of ethnicity in achalasia.
