Cepacia is not your run-of-the-mill germ. You can live with it for a long time, with not too terribly bad effects. But the problem is that at any time, the cepacia can break loose, get into the blood stream, cause sepsis, and then bam! you are dead in about 48 hours flat. Part of the work GSH does is to reduce inflammation. But there are those who say the excessive inflammation in CF actually protects those with cepacia--the excess inflammation, they believe, prevents the cepacia from going septic. So any anti-inflammatory that you would use would, under this theory, increase your chances of cepacia being able to go septic. I think there are some problems with this theory, but it is held by so many people that I think it wise to be quite cautious when you have cepacia. Nevertheless, we have had a few folks with cepacia using GSH who have reported only good results. As you say, the choice must rest with the person involved and their health professionals.
