I've had a really difficult result from my bone marrow biopsy today.
Four months ago I posted the effect of human Parvovirus on myself - in an immune-compromised person this virus can have the effect of inhibiting production of blood cells in bone marrow. Regular packed red cell transfusions have kept me going in this these months. With no improvement in this time a bone marrow biopsy now indicates that the loss of rbc production has most likely been caused by FCR (in particular Fludarabine). I completed 4 cycles in June 2018 with a good result. I understand the loss of rbc production is irreversible and I am faced with monthly transfusions for the rest of my life.
The only sign of hope here is that the regular intermittent fevers (around 2 each week for the first 5 weeks and more since) and sense of feeling very unwell at times may indicate that a virus is at work. At this point in time there don't appear to be any further tests which could be helpful. There were no positives to tests for Parvovirus, but I understand it can be difficult to test in an immune-compromised person.
The shock of this diagnosis is nearly equivalent to my initial CLL diagnosis 3 years ago.
