Abstract:
Objective:To investigate the etiological distribution of severe community-acquired pneumonia (CAP) in children in Hebei Province.Methods:The nasopharyngeal swab samples and clinical data from 314 children with severe pneumonia were retrospectively analyzed between January 2014 and January 2016.Results:Among the 314 children, 298 (94.94%) showed positive result for pathogens in their nasopharyngeal swab samples, with 246 cases (78.34%) of multiple pathogens, predominantly mixed viruses and bacteria (206 cases, 65.61%). A total of 848 strains of pathogens were detected, including 483 strains (56.96%) of viruses, predominantly respiratory syncytial virus with 97 strains of subtype A and 86 strains of B. Bacteria and atypical pathogens ( Mycoplasma pneumoniae) had 365 strains (43.04%), mainly Streptococcus pneumoniae (220 strains) and Haemophilus influenzae (119 strains). The detection rate of pathogens was higher in children under one year of age ( χ2=21.389, P<0.001). There were no significant differences in different seasons, but the detection rates of respiratory syncytial virus A, respiratory syncytial virus B, and Streptococcus pneumoniae were higher in autumn, winter, and spring, respectively, with statistically significant differences ( χ2=22.205, P<0.001; χ2=37.874, P<0.001; χ2=11.380, P=0.009). Conclusions:Nasopharyngeal swab sample testing in children with severe pneumonia typically shows a coexistence of viral and bacterial pathogens, with detection rates varying among different age groups and seasons. Nasopharyngeal swab sample testing for pathogens provides valuable references for the identification of clinical pathogens.
