I'm being lazy and just re-posting this:
My daughter Caitlin had the standard four doses of Rituxan one week apart in Sept.-Oct. 2002, after a year of ITP; she was 15 years old. IVIg and WinRho didn't do much for her, but Dex pulses took her to the low 100's; she dropped by about half each week til she'd get to retreatment levels of about 20-25K. But the Dex side effects got to be too much after about ten months, and we looked for something else. Going without treatment seemed pretty scary, because Caitlin's intro to ITP landed her in the hospital as a result of a menstrual cycle run amok; blood transfusions, surgery.. There weren't as many options then, and we really wanted her to keep her spleen. A second-opinion doc mentioned Rituxan, we mentioned it to her regular hemo--and a few weeks later, she started the infusions. She was not on any study, and our insurance covered it, no problems.
Caitlin says she felt like a guinea pig, and she was one of the earlier kids to receive it--there had been a few others, and that guided our hopes. No, it doesn't work for everyone, but when it does----! She received each infusion very slowly--took all day every time. No problems noted on doses one and two, but her lower leg bones felt achey after doses three and four. And she developed a mild case of pneumonia between doses two and three--it was going around at school. She was given antibiotics, and stayed on-schedule for her next dose. Her counts rose very early-she started below 33K, had 132K a week later, after receiving dose two. Was at 171K when she developed the pneumonia, at 136K a week later, and had dropped to 103K after dose four. That was Oct. 18; she hung around there for a month, but had risen to 225K by November 26, 2002---and has remained at about that level (her highest was 292K) on every CBC since that time, seven years, nine months ago!
Why has she responded so well? Wish we knew. While she did not continue on the dex pulses after starting Rituxan, she had had a pulse the month before. I'm sure it took the dex some time to get out of her system; there was likely only some residual level but--who knows? We offered them the option of a few extra vials of blood--they didn't think it would be helpful. She was released by the hemo after the four year check, I think. She's 23 now and knows what to watch for.
I have been posting from the beginning of her Rituxan remission, and read and print off everything I can find about it. Those who hit 100K usually get a year or more of remission; some folks who don't get the high counts do get a break from other treatments for a fairly long time. Other folks, it hardly seems to help at all. The other thing is, if you've had a splenectomy, the first few months after Rituxan should be an prudent exercise in germ avoidance. I've seen people of all ages report on their Rituxan experiences--it's worked only occasionally for young babies, so far as I can tell, but works for about half from pre-teen years and up. We are still waiting for more results on kids to be published, but there's a fair amount of research out there on Rituxan, if you look.
Rituxan has side effects that were rarely reported in 2002--namely PML and serum sickness. Don't know that knowing about about them would have changed our decision. Caitlin felt so vulnerable health-wise just when she was coming into her own; she was becoming a hypochondriac and was avidly plucking leg hair with tweezers. ITP affected her head greatly. It also limited her in the activities that had long been part of her life--horseback riding, Girl Scouting (they went white water rafting, rock-climbing). And she was due to start driving...and wanted to work with fanged creatures (wolves, primarily). We felt it would be great to give her a chance at a year without worries!
Of course, we are nothing but pleased, and sing the praises of Rituxan every chance we get--but it is a big decision. Still, if offered the chance I'd grab it NOW, before Obamacare hits! Because its use for ITP IS off-label, and it IS expensive and it doesn't work for everyone, I don't think you'll be seeing as much of it soon...
Good luck to each and every Rituxanite! To infinity and beyond with those platelets! Ann, Caitlin's (23) Mom
