Thanks kt14. I just spoke to sunderland actually and they were very helpful, although I'm still not sure whether our results are good, bad or inconclusive so I may email instead so I can re-read. My husband has a telephone consultation with our son's paediatrician in sweden on monday. He will have been sent a copy of the results, so I'd like to be as informed as poss!
I think she said yesterday that the results were not typical of a child with autism (and I think, by that, she meant moderate to low functioning autism), but that they wouldn't rule out an autism spectrum disorder. However, the fact that IAG is there at all baffles me. She also said that 10-15% of the population who would be considered perfectly mentally and physically healthy would still show some presence of IAG. However, with my son not doing any true declarative pointing, and the presence of IAG, they both feel like little signposts that merit further investigation.
She also said that with my son being so young (he's just gone 17 months), his urine would be quite diluted, so she wouldn't expect to see much activity anyway, and that the results may be quite different (ie higher) in a years time when he's had gluten/casein in his system for longer. Even though the explanatory letter said they couldn't say that a change in his diet would produce any significant benefit she suggested I give the dairy free diet a whirl anyway and suggested switching to rice milk and occasional soya cheese. Thinking about it I'm now confused as to why she suggested casein free rather than gluten free, given that IAG showed up rather than the casomorphin peptide.
As with your experience, some paediatrician's are supportive of a change in diet, and some aren't. Mine looked non plussed when I mentioned it to him a month ago when we first took our son, so I don't know how it will go on monday. We're hoping to get a referral to a christopher gillberg's team (although unfortunately not gillberg himself as his waiting list is about 1.5 years) at gothenberg university, so I hope the paed will do so as there is no other option but to go through him.
Interesting that you mention dyslexia (I must get the booklet out again!) - my husband suffered from this, I wonder if it's related.
Although the test hasn't come back completely positive, it hasn't given me the peace of mind I was hoping for and I'm feeling pretty low today. Not really helped by my mum going "He's pointing he's pointing!" when really he's just sticking his forefinger out by rote at nothing because he knows grandma goes wild with the cheering and whooping if he does that. When I point this out (pun intended!) she flounces and says "Right, well I just won't BOTHER then." I know she's as stressed about it as I am and just look for positive signs.
Sorry for the long ramble - sometimes it feels a bit better to write it down.
I really hope you see some benefits from the change in diet for your son kt14. How old is he? The lady said yesterday that the very young toddlers should show signs in about 3-4 months on a gluten free diet, and the older ones in about 10-12 months. Good luck and best wishes for you and your family!
