Eosinophilic gastroenteritis: epidemiology, diagnosis, and treatment.

PURPOSE OF REVIEW

Although several reviews concerning diagnosis and treatment of eosinophilic esophagitis (EoE) have been presented, there are few in regard to eosinophilic gastroenteritis (EGE). Fortunately, findings related to epidemiology, as well as diagnosis and treatment of this disease have recently been increasing.

RECENT FINDINGS

The rates of incidence of both EoE and EGE have been reported to be increasing. For accurate diagnosis, plasma concentrations of thymic stromal lymphopoietin and IL-33 may be useful as biomarkers, though consensus has not been reached, while increased eosinophil infiltration in gastrointestinal tissue remains a critical factor. Topical glucocorticoid administration, an elimination diet, and molecular target therapy with neutralizing antibodies are potentially effective therapies that have recently been evaluated.

SUMMARY

As seen with other allergic diseases, EGE seems to be increasing. Several research projects regarding diagnosis and treatment of the disease are currently in progress.
