Definitely not in remission. DS19 is doing much better, and I'm holding my breath (although he does keep having some fairly short-lived flairups.) DS-16 is still having a fair number of problems (resistent strep, lyme, and has high IgG to about 6 viruses, and mycoP.) So, he's chronically sick, but nowhere near as bad as prior to PEX and IVIG.
When you say "much better" what do you mean? Does he still have OCD and tics? Prayers that he gets better soon.
