I do frequent IV antibiotics, I'm sure that's what beat down the PA (and other bugs). My doc is a huge fan of the Danish method of CF treatment - 3 weeks of IVs every 3 months, rain or shine. Before I started this regimen my FEV1 was down to 65% and I was culturing PA, stenotrophomonus maltophilia, and mycobacteria avium. After a few years of this treatement my FEV1 was up to 82% and my cultures were clear of all bacteria, but in Feb of this year I started culturing PA again and also moraxella catarrhalis. <br>

Of course, the PA was probably never COMPLETELY gone, but all I know is for 10 months I spit in a cup and didn't grow any PA. I'm pretty happy with that result.<br>

65roses, nothing really changed in my treatment or lifestyle during that period. I did start the Denufosol trial in Sept. of '07, but that's the only real change, and that was well after my cultures were clear of PA. My work-related stress increased in Jan. of this year which might have contributed to culturing PA again. I'm a believer in the link between stress and illness. Things are finally slowing down a little at work, so hopefully I can get control of it again soon.
