About Eosinophilic Diseases

A group of uncommon chronic illnesses, eosinophil (E-0-’si-n-o-’fil) associated diseases, are rapidly emerging as a healthcare problem worldwide.  Yet, many patients suffering from there diseases go undiagnosed for years due to a lack of information or awareness of these diseases.

* High numbers of eosinophils accumulate in body tissues causing inflammation 
and damage.
* Classified by body tissue where eosinophils accumulate.
* Diagnosed and monitored by tissue biopsies.
* Chronic diseases requiring long term treatment, with no known cure.
* Debilitating diseases leading to missed work, school, social outings.
* Delays in diagnosis are common.
Eosinophilic Esophagitis
* Causes inflammation and damage to the esophagus, affecting the ability
to eat
* Estimated prevalence of more than 1 per 2000
* Increase in new cases (2 – 10 fold) over the past 10 years
* Patients may depend on steroids or medical nutrition therapy through
a feeding tube

Eosinophilic Gastroenteritis (EGE) and Eosinophilic Gastritis (EG)
     *  Causes inflammation and damage to the stomach and/or small intestine, often

     *  Estimate prevalence of EGE and EC combined is 1 per 3500
     *  Causes severe abdominal pain, forceful vomiting and/or diarrhea

     *  Treatment may involve a limited diet, feeding tube and/or steriods

Eosinophilic Colitis (EC)
     *  Causes inflammation and damage to the large intestine (colon)
     *  May be misdiagnosed as Irritable Bowel Syndrome (IBS) or Inflammatory bowel
     *  Patients may require restricted diet therapy, elemental formula or chronic steroids

Hypereosinophilic Syndrome (HES)
     *  Diagnosed by very high number of eosinophils in the blood and tissue

     *  Causes potentially fatal damage to one or more organs in the body (heart, lungs,
         gut, skin)

Churg-Strauss Syndrome (CSS)
     *  Eosinophils cause damage to small to medium blood vessels (vasculitis)
     *  Patient may be initally be diagnosed with severe asthma
