ADIPOQ and bronchiectasis: In this context, we speculate that adiponectin regulation might be traced back to two possible biological events: the former could be correlated to the interaction between adiponectin and the body composition of patients, which seems to be influenced by the co-existence of bronchiectasis; the latter could be due to the inflammatory state of patients exacerbated by exalted chronic inflammation, recurrent acute respiratory infections, or bacterial colonization of the airway.
