A 2-year follow-up study on these PW patients was conducted.

At the end of the 2-year follow-up, 20 children with PW (57.1%) experienced at least one episode of wheezing, and 15 (42.9%) did not suffer from wheezing episodes. Furthermore, PW children with recurrence also had increased abundances of <jats:italic>Elizabethkingia<\/jats:italic> and <jats:italic>Rothia<\/jats:italic> relative to those who had no recurrence. Additionally, wheezing history, different gender, and caesarean section demonstrated a greater impact in airway microbiota compositions.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>This study suggests that the alterations of lower airway microbiota could be strongly associated with the development of wheezing, and early airway microbial changes could also be associated with wheezing recurrence later in life.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1186\/s12931-021-01806-9","type":"journal-article","created":{"date-parts":[[2021,7,27]],"date-time":"2021-07-27T09:03:00Z","timestamp":1627376580000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Follow-up study of airway microbiota in children with persistent wheezing"],"prefix":"10.1186","volume":"22","author":[{"given":"Lei","family":"Wu","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chencong","family":"Shen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuanling","family":"Chen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xin","family":"Yang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaofei","family":"Luo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chengcheng","family":"Hang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lingling","family":"Yan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7148-846X","authenticated-orcid":false,"given":"Xuefeng","family":"Xu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2021,7,27]]},"reference":[{"issue":"3","key":"1806_CR1","doi-asserted-by":"publisher","first-page":"356","DOI":"10.1164\/rccm.201604-0694ST","volume":"194","author":"CL Ren","year":"2016","unstructured":"Ren CL, Esther CR, Debley JS, Sockrider M, Yilmaz O, Amin N, Bazzy-Asaad A, Davis SD, Durand M, Ewig JM, et al.
