eosinophilic gastroenteropathy

Dear Dr

Thanks for your advice on all my previous posts re my 31 month old son with low iron, low haemoglobin and blood in his stool.

We have made an appointment with a specialist paed for Thursday to discuss the results of all the blood tests and the biopsies after the gastroscopy and colnoscopy and the possibility of eosinophilic gastroenteropathy.

Before we see this dr though I would like to ask you if you think it could be eosinophilic gastroenteropathy caused by intolerance to milk even though the RAST test showed a result of only 0.02 for the Paed Mix for milk, wheat, soy, peanuts etc? (maybe worth noting that he had been fasting for about 18 hours prior to this blood test - not sure if that affects the result).

I was told this result is too low to indicate any kind of serious allergy that would result in bleeding.

I have read up on eosinophilic gastroenteropathy and believe it could be the case of the low iron as Vitamin D and Iron would be hard to absorb - does this ring true?

How do we get a definitive diagnosis for eosinophilic gastroenteropathy? Is there a specific test? I thought something like this would have been picked up in the gastroscopy and colonoscopy or from the biopsies take?

Lastly - my son seems to cosntantly suffer from a post nasal drip that causes him to cough in the morning and evening (not during the night and very little during the day). The cough is gagging and sometimes causes him to bring up food. It often becomes infected and antibiotics clear up the infection but nothing stops the post nasal drip. Steroids ease the cough a little but nothing permanent. He is on Avamys nasal spray daily and has had grommets put in and adenoids removed. The RAST test showed a 0.01 to Bermuda grass and no readings for dust mites, trees, timothy grass, pollen, cats dogs etc. Could this be related to the eosinophilic gastroenteropathy?

Thank you again! I hope with your advice and the specialist paed''s advice and treatment we get our son back on track.

There is often a cow's milk intolerance with eosinophilic gastroenteropathy but the RAST test may be negative.The diagnosis of eosinophilic gastroenteropathy is usually made on a biopsy sample showing masses of cells known as eosinophils in the lining of the stomach and intestines. The RAST test detects allergy to cow's milk due to a raised IgE, but not certain forms of cow's milk protein intolerance.Your son does not appear to be an allergic child and his postnasal drip does not appear to be due to an allergic cause. He may have infected sinuses at his age. His symptoms strongly suggest a post nasal drop problem. Use Sterimar nasal spray twice daily to clear his nose.
