The anticipated hospital stay is 3 to 4 days, when the first 3 doses of Campath will be monitored for drug side effects. The rest of the procedures, including the transplant, can be done on an outpatient basis. Follow-up visits for the first 3 months after the transplant will be scheduled once or twice a week for a physical examination, blood tests and symptoms check. Then, visits will be scheduled at 6, 12, 18, 24, 30, 36, and 48 months post-transplant. Visits for the first 3 years will include blood tests, skin biopsies, and bone marrow biopsies.
