My 9yo son was diagnosed in spring 2011 when he had the decending and most of the transverse colon affected.
We've been doing FT for him since Dec 2011. When we started he was on pred which meant he was able to retain the enema with no real problems. Once he was off pred we continued doing one daily enemas for 2 months then began weaning. Was doing one enema every 3 weeks when he had a minor flare 8 months later which we controlled with lowish dose of pred and daily enemas again. He weaned off pred again and was med free for 5 months until recently when he flared again. He was back on pred and daily FT and now med free again.
I do believe FT helps my son and the fact that he was med free for 8 months and then 5 months proves this. Would he have flared if we were doing enemas more frequently? I don't know. Borody suggested alternating donors and we will likely try this as we have another donor already tested.
I believe there is more to my son's UC that just a messed up flora. While I think FT has helped a lot it may only become part of his treatment rather than something alone that puts him in a long remission. Unless of course alternating donors does in fact make all the difference.
