My last crisis symptoms was 12/31/12, and hospitalized 5 days. Johns Hopkins had done the IFE panel to show changed in IgG and IgA but this wasn't emphasized to be a problem.I had not had an issue with ivig prior to this hospitalization. Reading the websites provided in this forum, the site states the IgA increase can cause anaphylaxis with IGG. I agree with seeing the Immunologist. I am very frustrated that I am thinking and scheduling soooo many Dr appts and trying to get a handle on my symptoms and diagnosis and have had zero help from any doors in ANY way. This confuses them and have told me to go somewhere more advanced because this is a complex case. I really hope to get the facts straight with help, and be able to figure this out. It seems I am the only one who cares!
