"I agree that prednisone is a last resort. \n \nHow sure are you that he is not getting gluten? Is he eating only naturally gluten-free whole foods that you can look at and verify that they are gluten-free? I mean foods like potatoes, eggs, a bunch of broccoli, meat you cook yourself, bananas, etc.  If it's processed you can't really check for gluten contamination. \n \nIf he is eating anything made from grains, he may be getting gluten.  We have had a few people on the board who cannot tolerate the traces of gluten that are common in commercial gluten-free breads and baked goods.  Grain products that are not labeled gluten free are not necessarily safe, even if they are made from safe grains like buckwheat or millet. Tricia Thompson bought a bunch of flours that should be naturally gluten-free and found gluten over 20 ppm in 7 of 22 samples, including one sample of soy flour with a whopping 2925 ppm gluten.  http://www.glutenfreedietitian.com/newsletter/contamination-of-naturally-guten-free-grains/  Other studies have shown there are sometime detectable traces of gluten in foods processed on shared machinery with wheat. \n \nAlso, is he off oats and dairy?  Casein and oat avenin can mimic gluten in some individuals.  If he is not eating grain-based foods, the next thing to try is removing oats and dairy. \n"
