I did find Julies posts on the sc ivig. They were interesting. It does seem from reading the posts that the sc ivig is only for maint. doses, not loading doses—puts me out–im on loading dose. But for others on a maint dose, may be worth checking.
there were some clinical trials when i googled– but a lot of criteria—and you may go through it all and receieve the placebo : ( Lori
