Hi there. My 4 year old son responds to steroids but after 2 years of frequently relapsing he is also considered steroid dependent. One week ago we started cytoxin/cyclosphosphamide after going into remission following a recent relapse (also tapering off prednisone). Unfortunately, after great intervention he still managed to get his brothers bad cold. He started off with a fever(is gone now) and is still really congested. Apart from his cold symptoms, his protein levels range between 1+ and 2+. My concern is, being on this new med i thought he would remain negative. I guess my question is, is it ok for his protein to fluctuate in the early stages of taking this new med? Is this a sign of it not working or is it too early to say its only been a week, and we should give it time? Has anyone with a child who has/had ster. dep. nephrotic syndrome used this med and remain in remission for sometime after treatment? Does anyone have/had any experience with this medicine or have any insights to this, that they can share? Any help, any insights will be greatly appreciated. Feeling a little disheartened, as was expecting more from this drug and was very disappointed not see a neg reading.
