I have ITP. I was diagnosed 35 years ago,was treated with prednisone and I went into remission for 35 years but never had a platelet count higher than 75k. 4 years ago I came out of remission when platelets dropped to 2k. I was told to get to an emergency room where I was started on 120mg of prednisone and put in ICU. Platelet count rose after a few days and I was released after 5 days and kept on 60 mg of prednisone for nearly a year. When tapering dose got below 20mg my platelet count dropped to 20k so docs got approved for injections of NPLATE. One weekly injection and after 8 weeks my count was way over 100k and docs stopped injections and for 4 years now my count stays in the 150-180k area.
My docs told me that removing the spleen would not necessarily be a cure. Check out this website. I learned so much about ITP. https://pdsa.org/
