<br>Has anyone heard anything about this? I just started taking zithro 3x per week last week,  <a href="http://www.news-medical.net/news/20110802/Azithromycin-may-predispose-cystic-fibrosis-patients-to-mycobacterial-infection.aspx">http://www.news-medical.net/news/20110802/Azithromycin-may-predispose-cystic-fibrosis-patients-to-mycobacterial-infection.aspx</a>

My sinus doctor had me on azithromycin for chronic sinus infection. The infectious disease doc in Denver took me off because it could cause my mycobacterial infection to become active.

This makes me nervous because I have been on it for years! I have major problems with inflammation and asthma so my doc thinks the pros outweigh the cons, but it still makes me nervous. I would love to hear what other CFers docs have said about this.

Very interesting. Thanks for posting. I think someone once posted about indications that ibuprofen use is also liked to NTMs.

Here is a bunch of text from an older study. The first paragraph notes that zithro in CFers might lead to zithro-resistant NTMs. So that's kinda tangential info to the link you posted. The second paragraph notes a possible link between the ibuprofen and NTMs. I guess the key being: We need antiinflammatories to prevent lung damage from our raging immune systems, yet dampening the immune fight can result in bacterias getting a foothold.

Azithromycin has a potential immunomodulatory effect in the treatment of CF, mainly for chronic P. aeruginosa respiratory tract infection (32). In our population, azithromycin was administered chiefly for its immunomodulatory properties and not to treat NTM pulmonary disease. Our study patients with NTM were treated more often with azithromycin (71.5% of case-patients vs. 51.4% of controls). Because macrolides are the treatment of choice for infections caused by MAC and M. abscessus, subtherapeutic doses of macrolides can induce selection of macrolide-resistant mycobacteria. The effect of long-term treatment with azithromycin on the antibimicrobial selection of NTM in CF patients remains undefined.

High doses of ibuprofen inhibit the inflammatory response to chronic infection, which contributes to lung destruction in patients with cystic fibrosis (33), and our patients with NTM were treated more frequently with ibuprofen. Furthermore, prostaglandin E inhibitors up-regulate the Th1 function with increasing levels of tumor necrosis factor, ?-interferon, and interleukin-2, which are necessary for the control of mycobacterial infections (34). The effect of prostaglandin inhibitors on mycobacterial infection has not been assessed in depth.

We did not find any correlation between the gene mutation profile and NTM infection. By contrast, others have demonstrated that 60.7% of patients with emerging bacteria were homozygous for the Delta F508 mutation in comparison to only 23.8% of the isolates from the control group (4).

Yes, Andrew was on 250 mg every M-W-F for years before he started culturing mycobacterium abcessus. His doctor immediately stopped it as a maintenance med. Interestingly, however, the last cocktail of meds we used for an 8 week treatment included zyvox, iv meropenem, inhaled amikacin, and 500 mg of azithromycin daily. Once treatment stopped we again discontinued the azithro. This cocktail was recommended for him by NIH.

Interesting my sister and I have been on azithromycin for years! (Possibly a decade or more)... and she started culturing mycobacterium abcessus as well. I wonder if this played a part in it.
