I've had cepacia for more than 10 years now; I remember what a worried look my doctors had on their faces, but despite their dire predictions, I have been functioning pretty well. My doctor likes to use multiple IVs at once to try to keep cepacia at bay. There's something about the combo of meds that makes the cepaciac calm down a bit.
I think the biggest bummer about cepacia is that it prevents us from being around other CFers from whom we could really draw support. Don't think of cepacia as a death sentence. Think of it as merely a complication of CF. Keep working hard at lung exercises, especially cardio, and you will be able to keep cepacia from sneaking up on you too often.
As to the transplant thing, there ARE centers that do cepacia transplants. Don't give up hope. Is transplantation is something you think you'll need, it's never too early to start talking with a transplant team and gathering information. Personally, I'm not willing to have a transplant because I know that it won't erradicate the cepacia in my sinuses. Nontheless, if you want to seek out a transplant team to discuss your options, I would say go for it!
All the best,
Lauren
