Hi Jamie
I can't answer your questions really. I was diagnosed in 2012, my daughter was born in 2011 and I've been trying for number 2 now for almost 18 months with no luck (long story - not for now).
I have had lots of chats with my haemo about rituximab though. He wanted me to try it. However when I argued that you have to wait a year AND remission lasts up to a year in the majority of people it works for we agreed not to bother. There is a study about rituximab which suggests that when it commences just after a dex pulse it is more likely to last longer but my haemo wouldn't consider that as an option - he felt it was too much to put my body through. We decided that the best course if action now is to "just get pregnant" (I wish!) and we'll deal with it from there. I do have every confidence in my haemo though and I trust his judgement.
Have you tried any treatments other than steroids? I have also tried ivig so I know that works & can be a backup for me.
