It has never been reported in a newborn. A male newborn, vaccinated against hepatitis B\u00a0and diagnosed with dilated cardiomyopathy, presented positive hepatitis B core antibodies at 12 days of life. Exclusion of hepatitis B\u00a0infection was mandatory as it would be a contraindication to heart transplant. Passive transfer of antibodies was confirmed at 44 days\u00a0of age, after seroreversion of hepatitis B core antibodies. Passive transfer of antibodies after intravenous immunoglobulin infusion can\u00a0lead to a misleading diagnosis if not recognized. In our patient it could have been especially harmful had it prevented heart transplant.\u00a0Screening for hepatitis B should be performed at least 1 month after intravenous immunoglobulin infusion.<\/jats:p>","DOI":"10.20344\/amp.9792","type":"journal-article","created":{"date-parts":[[2019,12,2]],"date-time":"2019-12-02T12:30:19Z","timestamp":1575289819000},"page":"782-784","source":"Crossref","is-referenced-by-count":2,"title":["Passive Transfer of Hepatitis B Antibodies through Intravenous Immunoglobulin in a Neonate"],"prefix":"10.20344","volume":"32","author":[{"given":"Jo\u00e3o","family":"Rato","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniela","family":"Alves","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lu\u00eds","family":"Rodrigues","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"8464","published-online":{"date-parts":[[2019,12,2]]},"container-title":["Acta M\u00e9dica Portuguesa"],"original-title":[],"link":[{"URL":"https:\/\/www.actamedicaportuguesa.com\/revista\/index.php\/amp\/article\/download\/9792\/5813","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.actamedicaportuguesa.com\/revista\/index.php\/amp\/article\/download\/9792\/5813","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,10,24]],"date-time":"2022-10-24T20:51:47Z","timestamp":1666644707000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.actamedicaportuguesa.com\/revista\/index.php\/amp\/article\/view\/9792"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,12,2]]},"references-count":0,"journal-issue":{"issue":"12","published-online":{"date-parts":[[2019,12,2]]}},"URL":"https:\/\/doi.org\/10.20344\/amp.9792","relation":{},"ISSN":["1646-0758","0870-399X"],"issn-type":[{"value":"1646-0758","type":"electronic"},{"value":"0870-399X","type":"print"}],"subject":[],"published":{"date-parts":[[2019,12,2]]}}}
