B-type natriuretic peptide is a useful biomarker predicting disease severity in children with isolated bronchiolitis in the emergency department. Turk J Pediatr 2017; 59: 561-569.

The aim of the study was to determine whether the B-type natriuretic peptide (BNP) plasma level predicted the severity of bronchiolitis without additional pathology in children admitted to an emergency department (ED). A total of 232 children (mean age: 7.7±1.2 months [range: 1–23 months]) presenting to ED with isolated bronchiolitis and 32 age- and gender-matched control subjects were included in the study. BNP levels differed significantly among the control (8.5±1.1 pg/ml) and mild (27.7±2.6 pg/ml), moderate (51.4±0.5 pg/ml), and severe (106.8±4.8 pg/ml) bronchiolitis groups (p<0.001). Clinical severity score (p<0.001; OR: 2.524; 95% CI: 1.826-3.487) and plasma BNP level (p<0.001; OR: 2.231; 95% CI: 1.583-3.242) were independent risk factors for hospitalization. The length of hospital stay was significantly correlated with BNP level (p<0.001; r: 0.698). In conclusion, the plasma BNP level may be a potent biomarker predicting disease severity in ED.
