Resumen
ROQUE GONZALEZ, Rosalba; PINOL JIMENEZ, Felipe Neri y ANIDO ESCOBAR, Vivianne. Eosinophilic esophagitis and esophageal acalasia. Rev Cubana Invest Bioméd [online]. 2021, vol.40, n.3 Epub 01-Sep-2021. ISSN 1561-3011.
Introduction:
Eosinophilic esophagitis is an emerging disease characterized by infiltration of the esophagus by eosinophilic leukocytes. Its main symptoms are dysphagia and frequent food impaction in the esophagus. Scientific evidence is now available that recognizes the disease as the possible cause of unfavorable evolution in patients undergoing Heller myotomy.
Objective:
Describe the biomolecular evidence associating eosinophilic esophagitis to esophageal achalasia.
Methods:
A systematic critical review was conducted of the evidence about biomolecular mechanisms associated to eosinophilic esophagitis and esophageal achalasia. The articles consulted were published in the databases PubMed, SciELO, LILACS and Scopus from 2015 to 2020.
Data analysis and integration:
A discussion is provided about crucial questions published recently concerning the study topic: Can eosinophilic esophagitis and esophageal achalasia coexist? Does eosinophilic esophagitis influence the result of esophageal achalasia treatment? What studies are required to establish the relationship between the two conditions?
Conclusions:
The cellular and biomolecular mechanisms triggered by eosonophilic infiltration contextualize the etiological and pathophysiological difference between eosinophilic esophagitis and esophageal achalasia. This explains the unfavorable post-myotomy evolution of patients and encourages the conduct of prospective controlled studies aimed at enhancing quality of life.
