What Are Bronchiectasis Biomarkers?

I’m not exaggerating when I say every bronchiectasis research article I read has the word ”biomarker” in it.

Typically measured in substances like blood, sputum, or stool, biomarkers offer valuable information about our health.
A familiar example is C-reactive protein (CRP) which rises with inflammation in the body. 🩸🩸

Another is the greenish tint to sputum caused by myeloperoxidase (MPO) .🦠🦠 MPO is a neutrophilic enzyme which is present when the body is waging a strong defense against bad-dude microbes.

Recent research presented at the 7th World Bronchiectasis Conference underscored the critical role of biomarkers. Scientists are diligently searching for immune system indicators in our bodily fluids that differentiate inflammation from healthy states. 

By identifying markers, such as cytokines which work as chemical messengers in the inflammatory process, inflammation can be proactively addressed before it escalates into infection. Also, to reduce the reliance on antibiotic treatments.

Moreover, reliable biomarkers will revolutionize treatment evaluation. Instead of relying solely on sputum, which can be challenging to obtain, we may soon turn to blood or other bodily fluids for assessment. 

This shift towards personalized medicine will enable tailored treatments based on each person’s biomarkers and areas of concern (ie a biomarker predicting the possibility of a future MAC or pseudomonas infection ) rather than a one-size-fits-all approach.
