Hi, ladies!
Sorry you haven't had many replies--holidays, you know. Look at the Treatments section on the home page, and you'll see that most of them are short-term solutions. How long each treatment is effective can usually be predicted from the same child's past response to it--my child may get only 2 weeks of counts over 60K, while someone else reports 100K for six months or even longer. That said, it is possible for a treatment that had been effective in the past to no longer be (as) effective--or even to stop making any knd of difference. Some people are non-responsive to one or two treatment possibilities, others are 'refractive'--and don't get much of a count boost from anything. The good thing is, there are several new meds in the pipeline, and great minds are working on the problem that is ITP.
Chronic is a label the docs slap on, some at 6 months, most at a year--but that doesn't necessarily mean forever. My daughter developed ITP at age 15, didn't respond much at all to IVIg or WinRho--but Dex pulses took her counts over 100 for a few weeks at a time. She was retreated about every 4-5 weeks. Side effects got to be too much (weight gain, hot flashes, bone loss, trichtillomania!), and at the one year mark, when she was officially 'chronic', we consulted with another doc who mentioned Rituxan. The first doc then picked up the ball and ran... Long story short, Caitlin had 4 doses in Sept-Oct 02, and she's still in remission, 7 years, 8 months later..... It only works for about half the folks who try it, but it can be quite remarkable! Since she had it, they've come up with N-Plate and one or two other new possibilities, but when it works, I think Rituxan has an edge on other treatments because after the four infusions (week apart), that's it (except a few more CBC's). With the others, they're weekly injections...
Also, other folks are MUCH more patient than we are and have kids who seem to handle it alot better. Over the 9 years or so I've been on this site, I've seen UNMEDICATED remissions many times, some after years of ITP. The crucial factor for most in making the decision not to treat is, are there active bleeding symptoms at the child's usual unmedicated count? If symptoms are few, and especially if counts are over 20-30K, and the treatments themselves leave the child feeling ill --then choosing to watch and wait is often possible or even preferable.
And yes, lots of people reports platelets drop with a virus--or any other infection!
As to your little guy with possible ASD, choosing not to treat will also depend on how he spends his day and how well he communicates. How active and risk-taking is he? Will he tolerate a soft helmet? Does he let you know if he hurts himself? Can you pad a room or an area for him, using those foam puzzle piece mats they sell everywhere? Have you been in touch with the Child Life specialist at your hospital--they can often provide help in these areas....
I wish your kiddos many platelets...to infinity and beyond! Ann, Caitlin's (23) Mom
