Is There a Correlation between New Scoring Systems and Systemic Inflammation in Stable Bronchiectasis?

Area of Science:

• Pulmonology
• Clinical Medicine
• Biomarkers

Background:

• Bronchiectasis is a chronic respiratory condition characterized by irreversible airway dilation.
• Systemic inflammation plays a significant role in the exacerbations and progression of bronchiectasis.
• Assessing disease severity and inflammation is crucial for effective patient management.

Purpose of the Study:

• To investigate the relationship between bronchiectasis severity scores (FACED and BSI) and markers of systemic inflammation.
• To determine if C-reactive protein (CRP), leukocyte count, and neutrophil/lymphocyte ratio are associated with bronchiectasis severity.

Main Methods:

• 117 patients with stable bronchiectasis had their FACED and BSI scores calculated.
• Correlations were analyzed between these scores and levels of CRP, leukocyte count, and neutrophil/lymphocyte ratio.

Main Results:

• Bronchiectasis severity scores (BSI and FACED) significantly increased with elevated CRP levels (p=0.001 and p=0.027).
• No significant correlations were found between FACED/BSI scores and leukocyte count or neutrophil/lymphocyte ratio.
• CRP emerged as a significant correlate of bronchiectasis severity.

Conclusions:

• C-reactive protein (CRP) is a valuable biomarker for assessing systemic inflammation severity in stable bronchiectasis patients.
• FACED and BSI scores are significantly associated with CRP levels, reflecting disease severity.
