Fifty\u2010one infants who were hospitalized during an initial episode of severe RSV bronchiolitis at 6\u00a0months of age or less were included and followed for up to the age of 3\u00a0years. Of them, 24 developed subsequent recurrent wheezing and 27 did not. Untargeted serum metabolomics was performed by ultraperformance liquid chromatography coupled with high\u2010resolution mass spectrometry (UPLC\u2010MS\/MS). Cytokines were measured by multiplex immunoassay. Difference in serum metabolomic profiles was observed between infants who developed recurrent wheezing and those who did not. L\u2010lactic acid level was significantly higher in infants with recurrent wheezing than those without. Pyrimidine metabolism, glycerophospholipid metabolism, and arginine biosynthesis were identified as the most significant changed pathways between the two groups. Moreover, L\u2010lactic acid level was positively associated with serum CXCL8 level. This exploratory study showed that differential serum metabolic signatures during severe RSV bronchiolitis in early infancy were associated with the development of subsequent recurrent wheezing in later childhood.<\/jats:p>","DOI":"10.1111\/apm.13095","type":"journal-article","created":{"date-parts":[[2020,11,6]],"date-time":"2020-11-06T08:47:48Z","timestamp":1604652468000},"page":"128-137","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Serum
