Microbial and clinical factors are related to recurrence of symptoms after childhood lower respiratory tract infection.

ABSTRACT: Childhood lower respiratory tract infections (LRTI) are associated with dysbiosis of the nasopharyngeal microbiota, and persistent dysbiosis following the LRTI may in turn be related to recurrent or chronic respiratory problems. Therefore, we aimed to investigate microbial and clinical predictors of early recurrence of respiratory symptoms as well as recovery of the microbial community following hospital admission for LRTI in children. To this end, we collected clinical data and characterised the nasopharyngeal microbiota of 154 children (4 weeks-5 years old) hospitalised for a LRTI (bronchiolitis, pneumonia, wheezing illness or mixed infection) at admission and 4-8 weeks later. Data were compared to 307 age-, sex- and time-matched healthy controls. During follow-up, 66% of cases experienc
