@lilianna You got the link exactly right.
Here is my experience - remember we are all different. The combination long-acting-beta-agonist (LABA) and low-dose inhaled corticosteroid (ICS) was a game-changer for me. I have long had difficult to manage asthma with hyperreactive airways, and (for over 5 years) bronchiectasis as well. Since diagnosis, I was antibiotics for nearly 2 years, and faithfully done airway clearance daily. About 2 years ago, when I complained yo my pulmonologist about my chronic chest pressure and shortness of breath in spite of daily levalbuterol & saline nebs and 4 or more times daily use of my rescue inhaler, she started me on Symbicort twice a day.

I now manage my asthma & bronchiectasis almost exclusively with the Symbicort and 3X weekly saline nebs. I have cut my exacerbations to zero (except now am battling something viral with twice daily saline & airway clearance) from an average of 2-3 per year.

So, while there may be no evidence for bronchiectasis alone, there is good evidence for those managing multiple lung conditions to use combination inhalers UNLESS (the doc stressed this) it results in a flare up of my long-suppressed MAC or Pseudomonas.

Thank you for posting this - it is another good piece of information in what I like to call "the puzzle of managing MAC & Bronchiectasis"
