Reply To: Is the plasma exchange working??

Typically, you should notice an improvement in a couple of weeks, if not sooner. However, you might need two or three rounds in order to see effect. Further, most textbooks say that PE has to be repeated every couple of weeks to maintain effectiveness. Taking those two ideas together suggest that two or three rounds of treatments spaced every 10 days to 2 weeks should be done before deciding that plasma exchange is of limited value. Waiting a couple of months to see if it worked seems to me to be out of line with standard experience. I would press your doctor for another round much sooner.
