Abstract

Objective: To analyze the clinical characteristics and factors associated with human respiratory syncytial virus (HRSV) infection in preterm infants within the first 2 years of life. Methods: Children with respiratory tract infections admitted to Shenzhen Children's Hospital during the 3-year period from January 2016 to December 2018 who were <2 years old and whose gestational age at birth was <37 weeks were selected, and those who met the diagnostic criteria for RSV infection were categorized as the positive case group, and those who had no detectable influenza virus, parainfluenza virus and adenovirus antigens were categorized as the negative group. The clinical characteristics of the case group were retrospectively analyzed. A multivariable logistic regression model was used to analyze the associated factors. Results: A total of 1, 483 children were included, of whom 149 (10.1%) were HRSV positive (case group) and 447 (30.1%) were in the negative group (control group). In the case group, there were 88 (59.1%) male and 61 (40.1%) female children; 127 children (85.2%) in the mild-to-moderate disease group and 22 children (14.8%) in the severe disease group. The number of cases in the severe disease group was greater than that in the mild-to-moderate disease group [(17 cases, 77.3%) than (59 cases, 46.5%)], with statistical significance (P=0.010). A total of 117 cases (78.5%) had onset from February to July. Multivariable analysis showed that males [OR (95%CI) of 0.105 (0.013-0.112)], age at month [0.045 (0.036-0.112)], congenital heart disease [0.388 (0.206-0.940)] and bronchopulmonary dysplasia [0.622 (0.484-0.927)] were positively associated with HRSV infection in preterm infants. Conclusion: The high prevalence of HRSV infection in preterm infants in Shenzhen is from February to July each year, and male children are more common. Young age, congenital heart disease and bronchopulmonary dysplasia are all independent risk factors for HRSV infection in preterm infants.
