Bbhope.... I really think it depends on what kind of immune issues you have. I have 7 different immune issues, so I think the meds work differently. One of mine is high ANA (anti-nuclear antibodies) - normally anti-bodies work to kill off colds, but because mine are high, they kill off good and bad, allowing me to have more colds. The Intrallipids/IVIG then work to balance the ANA, hence why no colds. Neupogen is a component of IVIG, so it's like taking a daily dose of IVIG and is the same as what cancer and HIV patients take (except in a very small dose). It doesn't lower the immune system, it's the opposite, gives the immune system a chance to work.
Chiefs..... thanks so much about the info on placenta issues. Sorry, I don't know anything about HLA matching, as that was never relevant to me.
Ladybug.... I will be doing IVIG throughout my pregnancy, but I believe the doses are the same. I do know that Dr M is getting me to do my full blood count every two weeks, in case he needs to change any Neupogen / IVIG doses.
