Vitamin D and disease severity in bronchiectasis.

Area of Science:

• Pulmonology
• Endocrinology
• Clinical Medicine

Background:

• Bronchiectasis is a chronic respiratory condition characterized by irreversible airway dilation.
• Vitamin D plays a crucial role in immune function and inflammation modulation.
• Vitamin D deficiency is prevalent in bronchiectasis patients and linked to poorer lung function.

Purpose of the Study:

• To investigate the correlation between Vitamin D levels and the clinical and radiological severity of bronchiectasis.
• To assess if Vitamin D serves as a predictor for bronchiectasis severity.

Main Methods:

• A cohort of 57 bronchiectasis patients (excluding cystic fibrosis and supplemented individuals) was studied.
• Bronchiectasis Severity Index (BSI) and Bhalla score were calculated for radiological assessment.
• Serum Vitamin D levels, inflammatory markers (ESR, CRP), and pulmonary function tests were performed.

Main Results:

• Vitamin D deficiency was observed in 64% of the study population.
• Vitamin D levels showed a significant correlation with both Bhalla score (R²=0.68) and BSI (R²=0.58).
• The correlation of Vitamin D with severity was stronger than that of ESR and CRP.

Conclusions:

• Vitamin D is a significant predictor of clinical and radiological severity in bronchiectasis.
• Monitoring and potentially supplementing Vitamin D may be beneficial for managing bronchiectasis patients.
