Hello, Welcome to HCM, I am Dr. Das
Look, MDS and PRCA is very rare disease condition. Here idiopathically or in case of some genetic abnormality, the bone marrow
fails to produce RBC
and thus it causes anemia
This anemia is refractory to any treatment. Depending upon the condition, Bone marrow transplantation
is very much helpful.
Another treatment option is colony stimulating factors.
Lastly, you should keep following up with your treating doctor.
