Himanshu, since you have consulted with various people, then it should be fine. You know as parents we always try to do the things that is best for our child. so, you are doing just that. Good luck!
Leena: you are right. chelation should never be stopped...but for little children who are still growing, there has to be a balance between chelation and growth. That is what I understood talking to my daughter's hemo both in boston and oakland. so start of chelation and how agressive the chelation should be when ferritin is below 500 varies from child to child.
Binita: what i know from Transfusion reaction is that you will get rashes or your pee will be coco-cola color and will have high fever. if none of those symptoms were there, the hospital should be able to do some tests to rule out Tx related issue. I do not know why liver will be enlarged. May be Andy can have some input there. For the ferritin, if it is 220 now, which is really low for a growing kid, your doc should advise you to reduce the dose to a maintenance dose and pay very close attention to creatinine, ALT/AST #s to make sure your child is doing ok. This input is based on what we have seen with my daughter.
