Elimination Diet.
 

It is thought that EGID is associated with allergies.   In the USA the first course of action for an EGID patient would be allergy testing.   This is   done by carrying out a series of tests such as skin prick testing and patch testing.   In the UK however allergy testing can be very difficult to get done,   NHS waiting lists are very long.   Because of this, you are more likely to be given a RAST (radioallergosorbent) test.   This is a blood test used to investigate allergies to a variety of food groups, mites and animal dander.   A positive result to a food will result in that food being eliminated from the diet, hence the name.   Depending on the results, an elimination diet may or may not be recommended.   Allergy testing can never be 100% correct,   a false negative (allergy not detected on testing) can lead to the failure of an elimination diet.   There are many stockists of dietary foods and some good books with advice and recipes.   Some of these are listed on our links page.

Medication.

There are no medications to cure eosinophilic disorders.   Medication can be used to suppress the eosinophils in the gastrointestinal tract and relieve symptoms of the disease.   Not all forms of EGID respond to the same treatments and different people with the same type may need very different medications.  

Medications which have been used in the treatment of EGID are listed below.   There is little published medical evidence in the UK of the benefits of any of these treatments, although there is some limited ongoing research:

Glucocorticoids (Steroids)   -   used to suppress various types of inflamation.   These are not specific to treat EGID although eosinophils have been known to be particularly sensitive to them.  The most common of these is Prednisolone.  Initially a high dosage will be given and then reduced over time to the lowest point where no adverse reaction is noted.

Leukotriene (luke-o-try-een)   Inhibitors   -   These are used to improve the symptoms in patients but do not necessarily improve the eosinophil count.   The most common of these used in the UK is Montelukast (Singulair).   As you can see from the link, this drug is used primarily in Asthma, it is known to relieve symptoms in other Allergic conditions.

Sodium cromoglicate -   This drug is widely use to treat food allergies   and most commonly used in the UK under the trade name of nalcrom.

Amino-salicylates - These are used in the treatment of inflammatory bowel disease (IBD), Crohns disease and Ulcerative Colitis (UC).   They are anti-inflamatory drugs and usually given in liquid form called Sulphfasalazine. 

Anti-histamine -   Anti-histamine drugs are already used extensively in allergic diseases such as Asthma and Eczema.   In the treatment of EGID, examples of those used are Zirtek (Cetirizine) and Zaditen   (also known as Ketotifen). 

Immunosuppressants -   These are used to reduce the activity of cells in the immune sysytem, they are used to enable a reduction in steroid dose and maintain remission in patients.   They are very powerful and have only been used in severe cases.   There are numerous side affects associated with these, and   need to be   monitored very closely.   Examples of those used are Azathioprine  and Cyclosporin. 

Other Medications - Patients with EGID commonly have other associated illnesses such as; Gastroeosophageal reflux disease (GERD), gastroparesis (delayed emptying of the stomach), eczema, asthma and other environmental/seasonal allergies.     Some of the drugs shown above can be used to treat these associated problems.   The treatment of other allergic problems is important in the control of EGID.

There are currently clinical trials in the USA for EE only. These have been in developing treatment that reduces the production or stimuli that attract the eosinophils.   More information can be found at the American Partnership for Eosinophilic Disorders (APFED).  Research in the UK has been carried out, but this is not widely available in the public domain.
