Hello robert and everyone in this group. I was diagnosed MG back in march 2023. My AchR-ab score was 28 before a thymectomy. Then after a bulbar crisis, I was treated with IVIG for 5 days every 3 months or so. I have being improved and my last infusion was last week after 5 months. My AchR-ab score is going down … right now it is 16 nmol/l (43% reduction rate)… it looks like IVIG not only helps to improve overall condition but it actually reduces production of AchR-ab…(I found a note on this from a MG medical paper)…keep in mind, as you sure know, IVIG does not work the same for everyone…
