of acid itself. A recent study, however, points toward a cause and effect relationship that is less clear, and demonstrated that inflammation may not be caused by acid reflux, but that both reflux and inflammation could be caused by an underlying third factor. It is a common misconception that reflux has been proven to cause inflammation in the esophagus.[https://www.medscape.com/viewarticle/863413]

Esophagitis that happens due to a viral, fungal, parasitic or bacterial infection. More likely to happen to people who have an immunodeficiency. Types include:

Eosinophilic esophagitis is caused by a high concentration of eosinophils in the esophagus. The presence of eosinophils in the esophagus may be due to an allergen, and is often correlated with GERD. The direction of cause and effect between inflammation and acid reflux is poorly established, with recent studies (in 2016) hinting that reflux does not cause inflammation. This esophagitis can be triggered by allergies to food or to inhaled allergens. This type is still poorly understood.

Overview

Esophagitis is a disease characterized by inflammation of the esophagus.[2]

Historical Perspective

Classification

  • Esophagitis may be classified into 6 subtypes/groups:
    • Reflux esophagitis
    • Infectious esophagitis
      • Fungal
      • Viral
        • Herpes simplex (Herpes esophagitis)
        • Cytomegalovirus
    • Drug-induced esophagitis
    • Eosinophilic esophagitis
    • Caustic esophagitis
