The aim of this study was to clarify whether administration of acetaminophen is related to an elevation of UB levels.<\/jats:p><\/jats:sec><jats:sec><jats:title>Method<\/jats:title><jats:p>Infants with a birthweight of \u02c21,500\u00a0g admitted to our neonatal intensive care unit between January 2017 and April 2020 were retrospectively reviewed. Seventy\u2010one infants were enrolled, five of whom had received acetaminophen. Clinical data were analyzed when the highest UB value (UB peak) in each infant was recorded. Demographic data and information on treatment within the 24\u00a0h before the UB peak were also collected. UB was determined by the glucose oxidase\u2010peroxidase (GOD\u2010POD) method. Infants were categorized according to the presence or absence of acetaminophen administration (acetaminophen and no acetaminophen groups) within 24\u00a0h of the UB peak. The relationship between UB values and various clinical variables was then compared.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Both the peak UB value and the ratio of gastrointestinal disease were higher in the acetaminophen group than in the no acetaminophen group. Univariate analysis revealed that a total of seven variables were potentially correlated with UB peak values (<jats:italic>P<\/jats:italic>\u00a0&lt;\u00a00.10). Multivariate analysis showed that acetaminophen and direct bilirubin were independently associated with UB peak values.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Our study suggests that administration of acetaminophen is related to higher UB levels by the GOD\u2010POD method. UB values measured by the GOD\u2010POD method should not be used in infants treated with acetaminophen for evaluation of bilirubin neurotoxicity avoidance.<\/jats:p><\/jats:sec>","DOI":"10.1111\/ped.14608","type":"journal-article","created":{"date-parts":[[2021,1,19]],"date-time":"2021-01-19T14:18:30Z","timestamp":1611065910000},"page":"1069-1074","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Acetaminophen elevates unbound bilirubin levels by the glucose oxidase\u2010peroxidase method"],"prefix":"10.1111","volume":"63","author":[{"given":"Shintaro","family":"Ichimura","sequence":"first","affiliation":[{"name":"Department of Perinatal and Neonatal Medicine, Aichi Medical University Aichi Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5557-0439","authenticated-orcid":false,"given":"Hiroki","family":"Kakita","sequence":"additional","affiliation":[{"name":"Department of Perinatal and Neonatal Medicine, Aichi Medical University Aichi Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shimpei","family":"Asai","sequence":"additional","affiliation":[{"name":"Department of Perinatal and Neonatal Medicine, Aichi Medical University Aichi Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mari","family":"Mori","sequence":"additional","affiliation":[{"name":"Department of Perinatal and Neonatal Medicine, Aichi Medical University Aichi Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Satoru","family":"Takeshita","sequence":"additional","affiliation":[{"name":"Department of Perinatal and Neonatal Medicine, Aichi Medical University Aichi Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiroko","family":"Ueda","sequence":"additional","affiliation":[{"name":"Department of Perinatal and Neonatal Medicine, Aichi Medical University Aichi Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tomoko","family":"Kondo","sequence":"additional","affiliation":[{"name":"Department of Perinatal and Neonatal Medicine, Aichi Medical University Aichi Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wataru","family":"Ohashi","sequence":"additional","affiliation":[{"name":"Department of Biostatistics Clinical Research Center, Aichi Medical University Aichi Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2447-2857","authenticated-orcid":false,"given":"Akihisa","family":"Okumura","sequence":"additional","affiliation":[{"name":"Department of Pediatrics Aichi Medical University Aichi Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yasumasa","family":"Yamada","sequence":"additional","affiliation":[{"name":"Department of Perinatal and Neonatal Medicine, Aichi Medical University Aichi Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2021,7,30]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1542\/peds.2008-2791"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.braindev.2020.06.010"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.siny.2009.12.004"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1053\/j.semperi.2004.09.005"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1542\/peds.2006-3024"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.clp.2016.01.003"},{"key":"e_1_2_9_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.siny.2014.11.001"},{"key":"e_1_2_9_9_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41390-018-0224-4"},{"key":"e_1_2_9_10_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1442-200X.2011.03457.x"},{"key":"e_1_2_9_11_1","doi-asserted-by":"publisher","DOI":"10.1042\/BSR20192152"},{"key":"e_1_2_9_12_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1442-200X.1992.tb01024.x"},{"key":"e_1_2_9_13_1","doi-asserted-by":"publisher","DOI":"10.1373\/clinchem.2008.121269"},{"key":"e_1_2_9_14_1","doi-asserted-by":"publisher","DOI":"10.1542\/peds.2005-0395"},{"key":"e_1_2_9_15_1","doi-asserted-by":"publisher","DOI":"10.1542\/peds.2016-4009"},{"key":"e_1_2_9_16_1","doi-asserted-by":"publisher","DOI":"10.1111\/ped.13635"},{"key":"e_1_2_9_17_1","doi-asserted-by":"publisher","DOI":"10.1177\/0148607110362529"},{"key":"e_1_2_9_18_1","doi-asserted-by":"publisher","DOI":"10.1097\/INF.0b013e31829044a8"},{"key":"e_1_2_9_19_1","first-page":"CD011219","article-title":"Paracetamol (acetaminophen) for prevention or treatment of pain in newborns","volume":"27","author":"Ohlsson A","year":"2020","journal-title":"Cochrane Database Syst.
