Hi Sandra. I'm so glad you were able to find us.
As Gretchen said, we were all afraid at first. As time goes on and you learn more about ITP, you will begin to relax. Honest, you will.
I will try to answer your questions. First of all, the big one - why do you have ITP? Very few of us ever found out the actual cause, or more accurately, the trigger. Sometimes it can take an accumulation of things to trigger it. For some people, it's a virus, a medication, an herbal supplement. For some people, it just popped up out of the blue and there wasn't anything they know of that preceeded it. At any rate, you could think of it like an allergy; your body doesn't like it's own platelets and reacts by producing antibodies to get rid of them. Sort of like a person who is allergic to pollen and reacts by sneezing. That is a very simple explanation, but one that a person can grasp. In time, you will learn more details that will make sense.
All of the treatments, including Rituxan and splenectomy, are just that; treatments. There is no cure. There are remissions and those can last weeks, months, years or a lifetime. Everyone reacts differently and remissions are different lengths for all of us. I had Rituxan in 2003 and was treatment-free for 13 months. I had Rituxan again in 2004 and have not had to treat since. I never thought I'd have a remission like this. I was diagnosed in 1998 and fought low counts on and off for years, mostly with Prednisone. Most people attain some type of remission and if not, they at least find a way to treat ITP and maintain safe counts (over 30) without too much disruption in their lives. It can take some time to get to that point though, so patience is key. Sometimes, the goal is to keep safe counts, not normal counts, although that is what everyone strives for in the beginning.
Very few people ever die from ITP. It's important to know that low counts do not mean that you will die. People with ITP tend to have large platelets that work well, and they also tend to have more tiny platelet fragments that help clotting also. Those are not counted when you have a CBC.
As for Rituxan, it is not a treatment to be taken lightly, but it can work well and most people do just fine. I got through the infusions with no problems and did work the next day. I did have a serum sickness reaction (rare) three weeks after the first infusion, but if I wouldn't have had that, it would have been smooth sailing.
You'll be okay. Read as much as you can, but be careful of which sites you visit. Some have outdated information and some are just not credible and full of incorrect information. The PDSA is about as accurate as it gets, as well as
