HI Shray,
I'm not sure if you would fit the eligibility for a BMT with most BMT centers, as you were transfusion independent for a long time. You may not transfuse often enough to be eligible. How often are you now transfusing? Have you talked to any of the doctors in India doing BMT's about doing one? Dr Ramanan in Pune has done some unrelated BMT's.
I would also like to mention that there is a new drug in trials that increases Hb, and is completely unlike hydroxyurea. The early trials had very good results. The phase 3 trials should start this summer and if all goes well, the drug will make it to market quickly, as it has been fast tracked. The drug is called Luspatercept and one of the doctors involved with this project is Dr Antonio Piga and he will be speaking at the conference in Delhi in September. If you can go, I would advise that you do and hear Dr Piga speak.
