BACKGROUND: Bronchiectasis is a complex respiratory disease characterised by permanent dilatation of bronchi. Vitamin D plays a role in infective disease by modulating the inflammation. Patients affected by bronchiectasis are frequently Vitamin D deficient and it correlates with lung function decline. We want to understand if there is a correlation between Vitamin D and clinical and radiological severity of bronchiectasis.
METHODS: We included 57 patients (17 males/40 female with mean age 60 ± 12 years) between October 2017 and March 2018. We excluded patients with cystic fibrosis, traction bronchiectasis and reporting Vitamin D supplementation. Bronchiectasis severity index (BSI) and Bhalla score were calculated, blood inflammatory markers and Vit. D were measured and lung function tests were performed.
RESULTS: Vitamin D is deficient in 64% of patients, sufficient in 36% and normal in 7%. Mean BSI is 7.5 ± 5 and mean Bhalla score is 16 ± 4. Vitamin D levels correlate with Bhalla score (R2 = 0.68, p < 0.001) and BSI (R2 = 0.58, p < 0.0001). The correlation appears to be stronger than other markers of inflammation such as ESR and CRP [R2 = 0.33, p = 0.001 and R2 = 0.39, p = 0.001 respectively].
CONCLUSIONS: We consider Vitamin D as a good predictor of clinical and radiological severity of bronchiectasis.
