DS14 has had two IVIGs, one in August and one in November 2010. The first one did nothing that I can tell--he got much worse for a while and then got barely back to baseline. He was on Omnicef, got some sort of exposure and went into exacerbation. I tried substituting OLE and the bottom dropped out, then we switched back to Azithromycin and shortly after that had IVIG again. This time, although we haven't seen the major getting worse part, we still haven't seen any improvement. The odd thing is, though, that we have kept the azith up for the whole 6 weeks even though we don't think we have ever seen any improvement on antibiotics, and DS had a stomach ache and I stopped the antibiotic since it appeared that it would just come back up. I didn't start the azith back up again for a while, just gave some OLE in case the stomach problem had been c.diff or something.
Rages suddenly started appearing, along with weird scary OCD stuff centering around hitting me (DS is 14 and 6 feet tall.) He never actually hurt me or even left a bruise, but he started to have daymares about really hurting me and how he would feel about that. His anxiety, consequently went through the roof, resulting in even more OCD. This was all occuring while he was trying to excel in his very competitive high school. (His art teacher, a wonderful woman who really likes him, called up and asked why he was continuously trying to start arguments with her in class.)
After a while it occurred to me that I hadn't restarted azith. I did that, and everything began to go back to normal. That was 3 days ago, and he is pretty much back to baseline, which isn't exactly great, but certainly better than last week.
This was a real surprise. We didn't see any improvement during the first trial of azith and we assumed it was having no particular effect, but apparently we were wrong. In fact, we were beginning to think that he didn't have PANDAS at all but just tourettes sadly complicated with developing OCD. But if the antibiotics are helping, but IVIG so far has not (after 17 weeks from the first ivig and 7 weeks from the second,) then ...what? Are we also lyme candidates? We did quest western blot and myco, with totally negative results. Maybe we need to try Igenex.
