Looking for advice as to whether we should do a second IVIG next week or not?
My 11yo PANS DS had his first HD IVIG 7 weeks ago, and his improvement is remarkable. The IVIG was really hard on him, with the migraine headache (which continued off and on for a week+), nausea, exhaustion, for about two weeks afterward -- and he did drink copious amounts of fluids both before and during the IVIG.
My typically functioning son had his first onset in January 2011 (not recognized as such at the time, but obvious in retrospect due in part to the handwriting decline, suicide threats, eating restrictions, and intrusive thoughts – the worst of that resolved within a month of onset), then a second, very dramatic onset in September 2011, thought to be sudden onset bipolar/OCD/anxiety/tics, until I finally figured out in Feb 2012 what was going on and he was diagnosed by Dr B and Dr L and began abx for a chronic sinus infection, which resulted in a dramatic improvement at first to 70% of normal, then a slow but up and down improvement to about 80% of normal when he was at his best. When he was about 80% (still with moderate school and social anxiety, tics, hyper, etc, but mostly functioning) we did an IVIG in early October.
Seven weeks post-IVIG, he's probably back to 95%, with virtually all anxiety, OCD, irritability just gone. No notable school anxiety in 3 weeks, and his social anxiety is also way, way down -- he's starting to reach out to people again and try to re-establish friendships. His tics are also way down, with only an eye twitch, small facial scrunching and occasional shoulder shrugging tic. He still has moments of being hyper and disorganized (ADHD symptoms), but they are not constant and seem to be when he’s excited about something and/or tired. He even got a fever for one day two weeks ago (turned out to be a cold sore/herpes) and we saw no ramping up of PANS symptoms at all. (Yay!)
So, we’re scheduled for another IVIG late next week. I am so thrilled with how well he’s doing. I am hesitant to do another IVIG at this time while we wait and see what further improvements the first one results in – the first one was so stressful and so hard on him physically. I think Dr. K and Dr. L both tend to just do one IVIG, and then wait a while and see what happens. We do our IVIGs with Dr. B, who typically does repeated IVIGs.
DS does have an immune deficiency – IGG1 consistently under 600 (normal is >820), serum IGG also below the normal level, (but it’s not really, really low), and no immunity to strep pneumonia despite being fully vax’d as a kid . He’s on treatment doses of both Augmentin (since Feb) and Zithromax (since June), 200 mg of ibuprofen/day, plus assorted probiotics.
Can anyone provide insights/advice about what they think we should do? Did anyone stop for a while after one HD IVIG to see how much improvement they could get from it? Did anyone keep going with a second HD IVIG just 8 weeks after a first one that seems to have been really effective?
