I am sorry that I don't have the original date of the post. Dr. Murray's post: Not medical advice I believe the issue of gluten challenge was addressed in a previous posting several months ago. Perhaps someone more able than I with computers can retrieve it. In brief There are not hard data on this and the differing views. I usually practise the following in adults. Have the patient take a small test dose like one wheat cracker for 2 days or so. Then if there has not been a horrible or dangerous reaction have the patient gradully increase the intake of gluten over several days to get to a dose of 3-4 wholemeal slices of bread a day. This is continued for 2-3 wekks if the patient has developed classic GI symptoms Diarrhea, bloating etc. If the patient has not developed any symptoms at all then I continue the diet for 3 months and check the antibody levels. If these are positive then I biopsy. If the patient is asymptomatic I continue the diet for a further 3-6 months and repeat the antibodies. The tricky bit is where the patient developes atypical symptoms. This situation needs to tailored to the individual case. A challenge must be discussed in advance with the doctor who must be kept updated on the advent of any symptoms. Too short a challenge or too little gluten may make it difficult to confirm the diagnosis. Much more research into this is needed and is being done in some European centers.
