At the end of August 2022, I was diagnosed with covid-induced ITP. I only caught it because all my extremities were covered in little red dots (petechiae). I made a freaking-out visit to the ER, and they diagnosed me after they did labs and my platelet count came back 0.
All these weeks later (October now), I've discovered I'm steroid resistant (dexamethasone and prednisone seemingly did nothing for me), and promacta (which I've been on for over a month) doesn't seem to be doing anything noticeable for my counts. I just finished my 4th of 4 doses of Rituximab on September 30th.
So far, I haven't seen any major improvements. I've been given IVIG like 4 times (8/9, 8/10, 8/17, 9/16) to stop me from bottoming out too low again while I wait for something to work, but no dice.
Does anyone have any info about how long it may take to see if Rituximab has worked? My doctor said 6-8 weeks after the last dose, but that's just around the corner and no boosts yet. I'm concerned.
Is there a world in which it just doesn't work? If so, what are my next options? Maybe this Nplate injection I've been hearing about? Was hoping there'd be something that would fix this altogether since I got ITP so quickly and it was virus-induced.
Thanks in advance for any responses.
