Is there a difference in the time spent in the hospital? From the graph it seems like immune system recovery is slightly better with the non-myeoblative but im not sure this translates into a shorter stay.
At any rate I think I would rather stay a little longer in the hospital if it ensures a more complete immune system memory deletion. Just my thoughts, not trying to put down the non-myeoblative method.
Based on an apples-to-apples treatment comparison, it is likely the non-myeloablative HSCT protocl could be completed with a shorter hospital stay. In fact, the non-myeloablative protocol can actually be completed as a pseudo-outpatient procedure in which the patient can sleep outside (but close to) the hospital but ready to come in if needed (based on regular blood and body temperatrure checks). This is how Prof. Slavin performs his non-myeloablative treatment at CTCI in Israel. A good example would be Hud's treatment in Tel Aviv in which he followed this routine. (But I also know that Dr. Burt is ultra ultra conservative with his treatment in Chicago and keeps patients in the hospital for a longer time which differs from Prof. Slavin's treatment. Probably the result of fear of malpractice lawsuits that are so common in the United States.)
However, a myeloablative HSCT protocol being a more serious procedure you wouldn't dare do such a (outpatient) thing. The patient needs to be monitored very closely and continuously in a hospital setting ready to immediately catch any/every complication, no matter how small. This is the only way to maintain safety of treatment. Likely it would require a minimum of 21 days hospital stay if everything goes normally and there are no complications, as was my case.
There's also no question that the myeloablative HSCT protocol results in complete (or nearly complete) immune memory erasure, confirmed by titer analysis which is why all myeloablative HSCT recipients need to be re-vaccinated. The non-myeloablative HSCT protocol only partially erases immune memory and thought to be "just enough" to stop MS, but not so much as to require re-vaccination.
