Latest EOSINOPHILIC ESOPHAGITIS

Eosinophilic esophagitis is an inflammatory condition in which the wall of the esophagus becomes filled with large numbers of eosinophils.
The esophagus is the muscular tube that propels swallowed food from the mouth into the stomach. Esophagitis refers to inflammation of the esophagus that has several causes. The most common cause of esophagitis is acid reflux which most frequently results in heartburn, though acid reflux also can cause ulcers on the inner lining of the esophagus. Other less common causes of esophagitis include viruses (such as herpes simplex), fungi (such as Candida), medications that get stuck in the esophagus (such as the antibiotic, tetracycline), and radiation (such as for treatment of lung cancer). Doctors believe that eosinophilic esophagitis is a type of esophagitis that is caused by allergy just like asthma, hay fever, allergic rhinitis, and atopic dermatitis even though the exact substance that is causing the allergy is not known. The hallmark of eosinophilic esophagitis is the presence of large numbers of eosinophils in the tissue just beneath the inner lining of the esophagus.
Eosinophils are white blood cells (leukocytes) manufactured in the bone marrow and are one of many types of cells that actively promote inflammation. They are particularly active in the type of inflammation caused by allergic reactions. Thus, large number of eosinophils can accumulate in tissues such as the esophagus, the stomach, the small intestine, and sometimes in the blood when individuals are exposed to an allergen. The allergen(s) that causes eosinophilic esophagitis is not known. It is not even known whether the allergen is inhaled or ingested. Eosinophilic esophagitis is more common among individuals with other allergic conditions such as asthma, hay fever, allergic rhinitis, and atopic dermatitis.
