Red cell transfusions & successful SCT
 

The other day I read on NORD somewhere, but, of course, can't find it again now, that having had red blood cell transfusions makes it less likely to have a successful stem cell transplant. Does anyone know if this is true and is it due to build up of iron or treatment for build up of iron or because of more difficulty of finding a match since you'd have other blood in your body besides your own? Thanks. Jo

There have been several articles that have reported a correlation between high ferritin levels (ie iron overload) due to a high number of RBC transfusions and poorer survival with stem cell transplants. Here is an article that specifically discusses MDS and AML with transplant.

The article says that there has been a correlation, but that the correlation may have complicating factors, meaning it may not really be the transfusions or the iron, but may be the condition of the underlying organs, which may be more susceptible to infection and stress due to lower hgb levels over prolonged periods of time.

This article contradicts the prior article by saying that age was the primary determining factor:

And here is one more with thalassemia patients that is both recent and seems to suggest that iron overload can be managed.

I would say that with new drugs, treatment regimens, and awareness of different complications, that the state of the medicine has been changing, and it is possible that what your doctors and transplant teams are working off of is different than what may be available for reading by patients.

It sounds like a great question for your doctor and/or transplant team to see how they would manage it in the future.

Hi JoMac53,

Prior to my transplant I had received over 100 units of PRBCs and was taking Exjade for iron chelation. My ferritin level was 524 and my transplant was a MUD with a 9 out of 10 HLA match...this was seven years ago this month (I was originally diagnosed in 2007 with 5q-).

I hope this helps answer your question.

Thank you...
 

...both for your replies. Very helpful. Sorry it took me so long to get back here. My life feels very disjointed right now, like I'm in a mirror fun (horror?) house and keep turning round and round with different things distracting me at every turn.
