We aimed to determine whether elevated levels of various inflammatory and immune proteins in umbilical cord blood are associated with an increased risk of newborn hearing screening (NHS) test failure in preterm neonates.<jats:italic>Methods<\/jats:italic>. This retrospective cohort study included 127 premature singleton infants who were born at \u226433.6 weeks. Umbilical cord plasma at birth was assayed for interleukin (IL)-6, complement C3a and C5a, matrix metalloproteinase (MMP)-9, macrophage colony-stimulating factor (M-CSF), and endostatin levels using ELISA kits. Neonatal blood C-reactive protein (CRP) levels were measured within 2 hours of birth. The primary outcome measure was a uni- or bilateral refer result on an NHS test. Univariate and multivariate analyses were applied.<jats:italic>Results<\/jats:italic>. Fifteen (11.8%) infants failed the NHS test. In the univariate analyses, high IL-6 and low C3a levels in umbilical cord plasma, funisitis, and an elevated CRP level (&gt;5\u2009mg\/L) in the immediate postnatal period were significantly associated with NHS test failure. However, the levels of umbilical cord plasma MMP-9, C5a, M-CSF, and endostatin were not significantly different between infants who passed and those who failed the NHS test. Multiple logistic regression analyses indicated that elevated umbilical cord plasma C3a levels were independently associated with a reduced risk of NHS test failure, whereas elevated levels of umbilical cord plasma IL-6 and high CRP levels in the immediate postnatal period were significantly associated with NHS test failure.<jats:italic>Conclusions<\/jats:italic>. Our data demonstrated that in preterm neonates, a systemic fetal inflammatory response reflected by umbilical cord plasma IL-6 and immediate postnatal CRP levels may contribute to the risk for NHS test failure, whereas the changes in complement activation fragments initiated<jats:italic>in utero<\/jats:italic>may have protective effect of hearing screen failure.<\/jats:p>","DOI":"10.1155\/2018\/4209359","type":"journal-article","created":{"date-parts":[[2018,9,19]],"date-time":"2018-09-19T23:57:57Z","timestamp":1537401477000},"page":"1-9","source":"Crossref","is-referenced-by-count":12,"title":["Inflammatory
