Hi John. I'm happy that you found us. I'll try to answer your questions.
1. It's impossible to give you a number that you'd hit 10 days after starting Prednisone. Everyone responds differently. Some people get a huge response, some a small response and some get no response. I was a great steroid responder and could get to 200k after four or five days of 60 mg's. It can work that fast for some people, so he's wrong about that. I have no idea how it will work for you. However, it's good that he's not suggesting frequent counts. Some doctors have their patients go every day and that is overkill. If you are not having symptoms, it's okay to space the CBC's out some.
2. His plan of keeping you on Prednisone for a while after you hit a normal level is a good idea. Ideally, a person should plateau and stay on the drug at the same dose for at least a few weeks, then begin a slow taper. Going faster might cause a crash then you have to start all over again. I've seen it happen many times.
3. Most people with ITP are on Prednisone for a few months (3 to 6) unless there is minimal response or no response. In that case, it doesn't make any sense to continue it and the taper should start. Any time spent on steroids is too long, but sometimes it's necessary. I can tell you about thinning skin. I was diagnosed with ITP in 1998 and was on and off of high doses a few times over the years. I only had short term side effects during that time. In 2006, I was diagnosed with Lupus and have been on 15 mg's since then. I am only now starting to have thinning skin. My experience is that it takes a while.
4. If after a month you are only at 100k, you'd have to evaluate then whether or not to continue Prednisone. It's not worth speculating about right now. There are so many if this and if that's, you'll go crazy trying to figure it out. If that happens, ask again and we'll help you to wade through the decisions. But whatever you do, do not just stop taking it. You're on a high dose which needs to be tapered properly.
5. You are probably going to have side effects. They hit everyone differently. The high dose side effects are different than the taper side effects. The best thing to do is be prepared, recognize them and strap in for the ride. You might begin to feel very wired, like you are on a caffeine high. You might have insomnia, mood swings, intolerance to noise, insatiable hunger, etc. Try to stay away from sugar and salt. Blood sugar can rise due to Prednisone and water retention can occur too. Some people get high blood pressure. Some people experience weight gain. Try to stay active and eat healthy. Some people experience loss of taste (I did, and ate hot salsa just to be able to taste something). Prednisone can also cause potassium levels to drop, so stay on top of it and eat bananas. You will get through it and when the taper comes, there is another whole list of side effects.
If you don't like your doctor, by all means, get another opinion. I'm never partial to doctors who want the spleen right away. Splenectomy is certainly not a cure and can bring about another whole set of problems. Read and learn as much as you can. Knowledge is the key to managing this.
