Thanks, Leela, and also for all of the great info re: the different types of ports. My goal is to do six more months of IVIG plus the two Ritux infusions (and possible maintenance doses, but that is to be determined later) without having to get a port. I don't believe that I need one and my veins are still okay and hoping that remains the case. But if that changes... you may be hearing from me again . Thank you @Binkie4 and this will be my official hashtag (even though I have never used Twitter in my life and don't even know how)! Thanks @PatJ for all of your support and if I am able to walk/drive again after Ritux, doing volunteer work is at the top of my list. Thank you and I wish I believed it would be that quick or easy but I am realistic and know that won't be the case. I think it takes about six months to start to feel the benefits (if you are a responder) but I have heard of some cases where people started to benefit after 3-4 months. I am guardedly optimistic. Am fairly certain now that they won't take away the IVIG and was able to schedule next IVIG cycle for next week. I honestly do not know what was the final factor that made my insurance reverse the denial and we have been working on this since March! Once it passes a certain point in the appeal process, the patient is no longer involved and it is between the patient's doctor and the doctor at the insurance who do a "Peer to Peer" review. I believe by the grace of God that we got a "Peer" doctor at my insurance who was sympathetic to my case. As far as diagnoses/autoantibodies, I have Autoimmune POTS & Dysautonomia, MCAS (mast cell disease), Hashimoto's, and a collection of 11 autoantibodies causing muscle & breathing weakness and overall autoimmune chaos. I have the calcium channel autoantibody that goes w/LEMS (which causes muscle & breathing weakness), GAD65 (which in my case links to dysautonomia and some symptoms of SPS prior to IVIG), the two Hashi's (anti-thyroid Abs), and 7 of the 9 Cell Trend Auto-Abs which include beta-adrenergic (link to POTS) and anti-muscarinic/cholinergic (link to muscle weakness). I also have positive ANA titer of 1:160, speckled pattern. I believe we explained how high dose IVIG put my MCAS into remission for entire ten months of treatment and greatly improved my muscle strength, breathing, stamina, etc, but it's temporary vs. Ritux could correct this and eliminate the need for IVIG if the new B Cells grow back healthy without all these damn autoantibodies. Having such a good response to high dose IVIG increases the chance I could be a responder to Ritux. I think we focused on my incredible symptom improvement from IVIG and that w/Ritux I could potentially get to the point of walking without wheelchair which I have not done since Oct 2014. My greatest hope in sharing all of this is that it helps someone else down the line.
