I can respond to your first question by sharing my story: I cultured PA for the first time about 10 years ago. The doctor prescribed three months of Cipro and Tobi. It didn't get rid of the PA (but it did give me C. diff!). I continued to do Tobi every other month for a year, then I moved and my new CF doctor took me off Tobi because my lung function was "too high" (I now disagree with that). Then I moved again a year later, and my new doctor put me on Colistin. I was on Colistin (every other month) for years. Then I stopped culturing PA, but my doctor kept me on Colistin for another year, until I got pregnant. I didn't culture PA again until this past spring, when I got a nasty virus that developed into bronchitis. During the time I wasn't culturing PA, I cultured either Staph or normal flora. Now I'm on Cayston and my last two cultures showed normal flora (no PA).
<br />
<br />So, it was like this: PA for 7 years, no PA for three years, PA again, and now no PA again. However, I am getting skeptical of my cultures and discussed this with my doc at clinic last week. I am not a big sputum producer, so my cultures are always throat swabs. EXCEPT the time I got sick this spring and coughed something up in the office - And then PA showed up! So I'm wondering if I really ever got rid of PA. My doctor agrees enough that he is interested in doing a bronch if my ENT wants to do a sinus surgery soon. I took some cups home with me so that I can drive them into his office the next time I cough something up.
<br />
<br />So, to answer your question, I know that PA is hard to get rid of. I'm not sure if you can. My cultures suggest maybe you can, but I am getting skeptical. IF the cultures are correct and I did get rid of it, I can say that I think it happened around the time I started hypertonic saline.
