PG - 365-72 LID - 10.1007/s00431-014-2405-4 [doi] AB - This cross-sectional study was performed to examine the prevalence of hypovitaminosis D in infants with acute bronchiolitis compared with control subjects and to evaluate the relationship between serum 25-hydroxyvitamin D (25(OH) D) and the severity of bronchiolitis. Serum 25(OH) D levels were measured by radioimmunoassay in 48 infants with acute bronchiolitis (2.5 +/- 2.0 months) and in 30 healthy infants (3.2 +/- 2.3 months). 25(OH) D levels (ng/ml) in children with acute bronchiolitis were significantly lower than in the control group (median 29.9 ng/ml (interquartile range (IQR) 21.4-37.5) versus median 38.2 ng/ml ((IQR 26.1-48.1), p = 0.022), mainly in infants with moderate-severe bronchiolitis (median 29.8 ng/ml, IQR 19.2-35.9). The prevalence of hypovitaminosis D was remarkably greater among infants with bronchiolitis than in control subjects (52.1 versus 26.6%). A significant inverse correlation was found between serum 25-hydroxyvitamin D levels and disease severity (rho = -0.457, p < 0.001). CONCLUSION: The prevalence of hypovitaminosis D is high in Spanish infants with bronchiolitis. The severity of acute bronchiolitis increases with a decline in serum 25 (OH) D level.
