Abstract:
Objective To investigate the correlation and clinical significance between the serum 25-hydrovitamin D3[25-(OH)D3] level and bronchiolitis in children. Methods Sixty-one children with bronchiolitis diagnosed by Xiamen Children′s Hospital between September 2016 and June 2017 were enrolled in the study. Forty-one healthy children were used as the healthy control group. All the children were tested by enzyme-linked immunosorbent assay for serum 25-(OH)D3levels and serum IgE,IgG,IgA and IgM content. The clinical data of children with bronchiolitis group were recorded in the meanwhile. Results (1) Com-paredwiththehealthycontrolgroup,theserumlevelsof25-(OH)D3[(59.47±23.66)nmol/Lvs.(69.94± 25.19)nmol/L],IgM[(1.27±0.49)g/Lvs.(1.56±0.43)g/L]andIgA[(1.38±0.83)g/Lvs.(1.71± 0. 61)g/L] were significantly lower in children with bronchiolitis;while the serum IgE[(106. 59 ± 67. 74) IU/L vs. (75. 95 ± 35. 27)IU/L] was significantly higher(P<0. 05). (2)The serum levels of IgE,IgG and IgA in children diagnosed bronchiolitis with vitamin D deficiency [( 177. 37 ± 82. 72 ) IU/L, ( 5. 46 ± 1. 95)g/L and(0. 68 ± 0. 24) g/L] were obviously different from those of children diagnosed bronchiolitis with vitamin D inadequate[(94.21 ±44.21)IU/L,(7.14 ±2.82)g/L and(1.35 ±0.72)g/L] and vitamin D normal group[(79. 60 ± 44. 30)IU/L,(8. 03 ± 2. 49)g/L and(1. 57 ± 0. 78)g/L](P<0. 05). There was no significant difference about serum levels of IgE,IgG,IgA and IgM between vitamin D inadequate and vita- min D normal group(P>0. 05). (3)The wheeze time was higher in bronchiolitis children with vitamin D deficiency[(3. 97 ± 1. 01) d] than those of patients with vitamin D inadequate[(2. 41 ± 0. 79) d] and vitamin D normal group[(2. 27 ± 0. 88)d](P<0. 05). The level of venous glucocorticoid utilization was higher in bronchiolitis children with vitamin D deficiency than that of patients with vitamin D normal group (58. 82% vs. 29. 03%)(P<0. 05). There was no significant difference about clinical data between vitamin D inadequate and vitamin D normal group(P>0. 05). Conclusion The serum 25-(OH)D3levels are lower in children with bronchiolitis than those in healthy children. The lower the level of vitamin D,the more severe the children with bronchiolitis. Vitamin D deficiency is an important cause of bronchiolitis in children,which may be related to immune dysfunction effected by vitamin D deficiency.
