norcalmom,
Good for you and your son! My daughter who was being treated with Augmentin 1000 xr was doing very well, most of the OCD along with other symptoms disappeared. She still had some lingering OCD though and it was not till we added Biaxin to the mix that the final OCD left.
She never had any high strep titers or strep symptoms, but her mycoplasma IGG was high on the lab test. (different scale then yours but high) Her Igm was negative.
I had written to that doctor you speak about with the gulf war syndrome he did say that Igg should be treated, he was careful not to say what I should do but that positive Igg and negative Igm he would treat.
We had it tested only one other time the number had dropped a bit, but was still in the high range, she had been on augmentin but not the biaxin at that time if I remember correctly, we never did check it again. I think I had written some place in here about it when we were trying to figure out whether to treat or not.
Hope the new antibiotics do if for your son! It really made all the difference for her!
