Abstract:
Objective:To investigate the differences of clinical characteristics and leukotrienes (LTs) level of bronchiolitis children infected with respiratory syncytial virus (RSV), human rhinovirus (HRV) and human metapneumovirus (hMPV), and provide clinical evidence for the treatment of bronchiolitis with LTs receptor antagonist (LTRA) montelukast.
Methods:Totally 90 children with bronchiolitis hospitalized from January 2017 to December 2018 were enrolled into this study and viral nucleic acid from respiratory tract specimens were detected; and the patients were divided into three experimental groups: RSV group, HRV group and hMPV group. The clinical data and LTs level in blood and urine of experimental groups were compared; 30 healthy children were enrolled as the control group.
Results:There were no significant differences in age, sex, weight, family history and past history of allergy among the three experimental groups. The LTs levels in the experimental groups were higher than that of control group (P<0.05). There was a positive correlation between the LTs levels in blood and urine (r=0.723, P<0.05). In RSV group, LTs level of was the highest, lung function was the worst, and clinical score was the highest, and significantly different from those of HRV group and hMPV group (all P<0.01). However, there was no significant difference between HRV group and hMPV group. The number of days with fever of RSV group and hMPV group were not significantly different, but both were higher than that of HRV group (all P<0.01). The number of days with cough and wheezing among experimental groups had no significant difference(all P>0.05).
Conclusions:The bronchiolitis children infected with RSV had the highest LTs level, the worst lung function and the highest clinical score, there was significant difference when compared with HRV group and hMPV group.
