We had Jackson's first follow-up blood draw this morning, and the news is good! His platelet count is up to 392,000! We are so, so grateful for how well the IVIG has worked for him so far.
Some things I learned from the doctor today... Jackson has a 90% chance of having Acute ITP - I was happy to hear the odds on that. Acute ITP lasts anywhere from 2 to 6 months. During that time, there is a somewhat decent chance he will have to get another treatment if his platelet count goes back down once the IVIG wears off (usually wears off between 3 and 8 weeks after receiving it). Because of his excellent response to the treatment, we get to wait 3 weeks before getting another blood test (but we'll need to be watching closely for new bruises, nosebleeds, etc.). The results to that blood test will determine the frequency of more tests in the future.
If 6 months pass and we're still dealing with drops in platelets, it will mean he has Chronic ITP. The doctor said that he would have it for the rest of his life, although I HAVE heard of children with Chronic ITP going into remission.
We are so feeling so grateful today for our little Jackson.
