MgSO&lt;sub&gt;4&lt;\/sub&gt; crosses the placenta and can affect the neonate. Magnesium homeostasis in extremely low birth weight (ELBW) infants remains to be clarified. &lt;i&gt;Objectives:&lt;\/i&gt; We aimed to assess the natural progression of serum magnesium (Mg) in ELBW infants not exposed to antenatal MgSO&lt;sub&gt;4&lt;\/sub&gt; during the first month of life. &lt;i&gt;Methods:&lt;\/i&gt; Laboratory data of a group of ELBW infants born in a tertiary center over a 1-year period were analyzed. Serum Mg was recorded daily for the first week and thereafter each week for a month for each infant. Concurrent calcium, phosphate and alkaline phosphatase were measured. &lt;i&gt;Results:&lt;\/i&gt; 51 preterm infants (24 female) with a birth weight &lt;1,000 g were included (33 were born at &lt;27 weeks\u2019 gestation). The mean magnesium ranged from 0.9 to 1.1 mmol\/l over the first week with a minimum of 0.62 mmol\/l and maximum of 1.53 mmol\/l. Mg rises in the first few days before stabilizing and remains within a narrow range thereafter. &lt;i&gt;Conclusions:&lt;\/i&gt; In ELBW infants, Mg tends to rise initially then stabilize and remain normal thereafter. The effect of antenatal MgSO&lt;sub&gt;4&lt;\/sub&gt; on magnesium homeostasis requires further study.<\/jats:p>","DOI":"10.1159\/000335240","type":"journal-article","created":{"date-parts":[[2012,1,16]],"date-time":"2012-01-16T11:19:15Z","timestamp":1326712755000},"page":"274-277","source":"Crossref","is-referenced-by-count":6,"title":["Serum Magnesium in the First Week of Life in Extremely Low Birth Weight Infants"],"prefix":"10.1159","volume":"101","author":[{"given":"D.","family":"Noone","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"E.","family":"Kieran","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"E.J.","family":"Molloy","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2012,1,14]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1038%2Fsj.jp.7211419"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1159%2F000319049"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1007%2FBF00866716"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1080%2F08035320510043619"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1046%2Fj.1440-1754.2000.00451.x"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1007%2Fs00467-008-1060-2"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1681%2FASN.2008010098"}],"container-title":["Neonatology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/335240","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/335240","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T18:55:19Z","timestamp":1745434519000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000335240"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2012]]},"references-count":7,"journal-issue":{"issue":"4","published-online":{"date-parts":[[2012,6,1]]},"published-print":{"date-parts":[[2012,5,24]]}},"URL":"https:\/\/doi.org\/10.1159\/000335240","archive":["Portico"],"relation":{},"ISSN":["1661-7800","1661-7819"],"issn-type":[{"value":"1661-7800","type":"print"},{"value":"1661-7819","type":"electronic"}],"subject":[],"published":{"date-parts":[[2012]]}}}
