Abstract:
Objective To explore the clinical characteristics of human bocavirus (HBoV) infection in the children with severe lower respiratory tract infection.Methods The clinical data of the hospitalized children with sputum HBoV-positive were analyzed retrospectively,who were hospitalized at the Pediatric Intensive Care Unit of Children's Hospital Affiliated to Capital Institute of Pediatrics from September 1,2016 to March 31,2017.Results A total of 17 children were included in the study.The ratio of male to female was 15 ∶ 2.The diagnostic age ranged from 4 months to 4 years and 10 months old.82.4% (14/17 cases) of the patients were infants less than 2 years old.Autumn and winter were high-occurrence seasons.Pediatric Critical Illness Scores(PCIS) were 68-88 scores(median 82 scores).PCIS was less than 70 scores in 1 case,and between 70 scores and 80 scores in 7 cases,and more than 80 scores in 9 cases.The main clinical manifestations were respiratory system involvement,including dyspnea in 17 cases (100%),fever in 14 cases (82.4%),cough in 16 cases (94.1%),wheezing in 13 cases (76.5%),and moist rales in 13 cases (76.5%).The main abnormal chest radiological findings showed patchy shadows in 7 cases (41.2%) and consolidation in 6 cases (35.3%).The oxygenation index was 73.9-296.0 mmHg(1 mmHg =0.133 kPa),and median was 176 mmHg.The oxygenation index was between 100-200 mmHg in 7 cases(41.2%),and less than 100 mmHg in 2 cases(11.7%).Type Ⅰ respiratory failure occurred in 11 cases (64.7%),while type Ⅱ respiratory failure occurred in 6 cases (35.3 %).All of the patients need respiratory support with mechanical ventilation.Among them,6 patients (35.3%) were treated by non-invasive ventilation and their ventilation time were 25-128 h(median 65 h),while 11 patients (64.7%) were treated by invasive ventilation and their ventilation time was 42-178 h(median 70 h).Other organ or system dysfunction is mild.The length of hospital stay ranged from 3 days to 13 days.The cure rate was 100%.Conclusions HBoV infection in the children with severe lower respiratory tract infection is common in infants under 2 years old,with acute onset and rapid recovery.The obvious clinical symptoms are fever,cough,wheezing and dyspnea.Although respiratory failure is common,other organ or system dysfunction is mild,which may bring about a good prognosis.
