Hey there, I am 16 mos remission with the help of Campath. (Sorry was on vacation and didn't respond sooner) My hgb got down in the 6s and I had 50 transfusions to keep me going until we got the Campath approved. ( Did the Methotrexate and Penstatin with no improvement) Six weeks after treatment with Campath I was walking at Universal Studios, a bit weak mind you, but I was walking without a cane in months. No adverse effects from the Campath, other than initial pain with the shots. (They put the shots in your leg before moving on to I.V. ) My hgb was 13.4 last week - an all time high! I swim, bike, walk, am perfectly normal for now. I do recommend it! And will be happy to answer any questions I can.
