Now that her IgG4 count is greatly reduced, my sister Mary was retested and rediagnosed with
Rosai Dorfman disease and will be treated with chemotherapy
drug Gleevec in pill form for at least 3 months starting mid June. Meanwhile she takes 30 mg of Prednisone.
I'm not in the health profession, but based on my sister's experience, I highly recommend that everybody with a diagnosis of IgG4 get their food intolerances tested and stop eating any intolerant foods.
