Eosinophilic Cystitis and Interstitial Cystitis: may allergy be the reason?

Allergic diseases have increased in prevalence during recent years. Although they impose numerous health and financial burden on patients and their family and also the society, they are to some extent preventable and manageable. While reviewing the literature to find any relationship between allergic disease as the familiar and preventable conditions and the two unfamiliar entities, named Eosinophilic Cystitis (EC) and Interstitial cystitis(IC); a significant number of reports were found about the etiological roll of atopy and allergy in the development of these conditions. Nevertheless this relationship is stronger concerning IC than EC. Referring to allergy as a contributing factor makes it more understandable and controllable. Although in order to reach a proper conclusion more thorough studies are required.
