Further to Claude's point, and as an important clarification on Jeff's' (_jisenhour_) troubling post, above:
At first sight, Jisenhour's entry appears to be the first reported failure of IVIG therapy from any one of our many RareShare patients who have been on IVIG for 1-6 years. It is also troubling especially since IVIG had stopped his previously frequent episodes for many months.
However, I spoke with him yesterday and it turns out that, as Walt wondered in his post above, Jeff had been getting only half of the recommended dose, namely, 100gr of IVIG once a month (for someone who weighs about 100kg).
Jeff told me that neither he nor his doctor knew that this was only half the recommended amount, but now that they know, he has received two 100gr doses -- which is what explains his comment that his previous dose (of 100gr once a month) has being doubled.
While we are all sorry for his January relapse and for his pain and suffering (e.g., he underwent some preventive abdominal surgery during his hospitalization, and his lungs were at risk), Jeff may have unwittingly provided us all with an extremely valuable data point: namely, he may have confirmed that a single monthly dose of 1gr/1kg of IVIG is NOT enough, and the proper amount is 1gr/kg of IVIG for two days in a row (namely, 2gr/kg per month), as the rest of us is getting.
