I have not been diagnosed with haemophilus B, nor any pathogen. Cultures x 2. Nothing grew.
Bronchoscopy- confirmed Bronchietasis and cultures for affected area of lung sent. Again, negative.
Haemophious B, is a very common colonizer and can cause exacerbations in bronchietasis, driving inflammation, impairs mucous clearance and may create a cycle of infections and damage.
It is a treatment challenge.
As mentioned by Sue cultures and airway clearance as very important.

1. Have you been cultured for other pathogens. Pseudomonas, Staph aureus, Non-Tuberculosis Mycobacteria NTM- Can be present and missed by standard cultures, Resistant to azithromycin.
And several others- FUNGI, Legionella, Moraxella, Klepsiella.

3. Have they prescribed a inhaler?
4. Or a nebulizer - fine mist to thin mucous, ease coughing, open airways, improve breathing by directly targeting lung.

5. Have you had a PFT? Help determine lung function, severity of bronchietasis and target best treatment options.

6. Are your immunizations up to date: Covid, Flu, Pneumonia, RSV? Check with pulmonologist for recommendations (based on history, age, vaccines).

Hope I have been helpful.
