@jeffhampton Curious if your doctor has discussed the possibility of a DLI (donor lymphocyte infusion). This is an infusion of lymphocytes from your donor which may give an extra nudge to a sluggish immune response if there is a mixed chimerism. Sometimes that’s all it takes to get the numbers (and chimerism) where they need to be.

I know you’re feeling so discouraged right now but hang in there, Jeff. It gets better! Like I said before that first year can be really challenging…tests one’s mettle for sure! Especially having a lower hemoglobin and being a marathon runner. But give yourself some grace. Your body has been through ‘heck and back’ and it takes time to heal from that level of trauma. So as frustrating as this break from running is, this is the time to do down time maintenance on your body. Rest, recovery, healthy foods, plenty of water, low to moderate exercise, and more rest. Let your body, mind and soul recover while setting future goals. Do you think, even if you can’t enter the race, you’ll still attend the Leadville 100?
