Colonisation with Pseudomonas aeruginosa is a feature of bronchiectasis and is associated with more severe disease and lower quality of life.1 Nebulised colomycin, a polymixin, bactericidal antibiotic with potent activity against most Gram-negative organisms, including P aeruginosa, is frequently employed in these patients, but evidence is lacking for this approach.

We have retrospectively assessed the efficacy of nebulised colomycin in P aeruginosa-colonised patients receiving a minimum of 6 months treatment. Patients who received concomitant prophylactic macrolide treatment for >4 weeks were excluded. Bronchiectasis was confirmed in all patients by standard high-resolution CT criteria, and all received nebulised colomycin 1–2 megaunits twice daily through a standard jet nebuliser …
