We investigated preterm delivery phenotypes in SLE and general population comparators and assessed the role of preeclampsia.<\/jats:p><jats:p>\n            Study Design\u2003We used population-based Swedish Register data (2001\u20132013) and defined maternal SLE as \u22652 SLE-coded discharge diagnoses from the Patient Register with \u22651 coded by an appropriate specialist. Women from the general population were identified using the Total Population Register. Preterm delivery was defined as &lt;37 weeks and separated into spontaneous and iatrogenic, as well as later versus extremely preterm (32 to &lt;37 weeks vs. &lt;32 weeks). Maternal comorbidity was assessed, and the proportion mediated by preeclampsia was calculated examining first, subsequent, and all pregnancies.<\/jats:p><jats:p>\n            Results\u2003Preterm delivery was more common in SLE for the first (22 vs. 6%) and subsequent (15 vs. 4%) pregnancies among 781 SLE-exposed pregnancies and 11,271 non-SLE pregnancies. Of SLE-exposed first births, 27% delivered before 32 weeks, and 90% were iatrogenic (compared with 47% of non-SLE first births).<\/jats:p><jats:p>\n            Conclusion\u2003Preterm delivery complicates a greater proportion of SLE pregnancies than general population pregnancies, and a considerable proportion of risk is mediated through preeclampsia.<\/jats:p>","DOI":"10.1055\/s-0038-1675648","type":"journal-article","created":{"date-parts":[[2018,11,26]],"date-time":"2018-11-26T23:52:27Z","timestamp":1543276347000},"page":"964-968","source":"Crossref","is-referenced-by-count":13,"title":["Preterm Delivery Phenotypes in Systemic Lupus Erythematosus Pregnancies"],"prefix":"10.1055","volume":"36","author":[{"given":"Julia F.","family":"Simard","sequence":"additional","affiliation":[{"name":"Division of Epidemiology, Department of Health Research and Policy, Stanford University School of Medicine, Stanford, California"},{"name":"Division of Immunology and Rheumatology, Department of Medicine, Stanford University School of Medicine, Stanford, California"},{"name":"Clinical Epidemiology Unit, Department of Medicine Solna, Karolinska Institutet, Stockholm, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yashaar","family":"Chaichian","sequence":"additional","affiliation":[{"name":"Division of Immunology and Rheumatology, Department of Medicine, Stanford University School of Medicine, Stanford, California"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marios","family":"Rossides","sequence":"additional","affiliation":[{"name":"Clinical Epidemiology Unit, Department of Medicine Solna, Karolinska Institutet, Stockholm, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anna-Karin","family":"Wikstrom","sequence":"additional","affiliation":[{"name":"Clinical Epidemiology Unit, Department of Medicine Solna, Karolinska Institutet, Stockholm, Sweden"},{"name":"Department of Women's and Children's Health, Uppsala University, Uppsala, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gary M.","family":"Shaw","sequence":"additional","affiliation":[{"name":"Division of Neonatology and Developmental Medicine, Department of Pediatrics, Stanford University, Stanford, California"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maurice L.","family":"Druzin","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Stanford University, Stanford, California"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"194","published-online":{"date-parts":[[2018,11,26]]},"container-title":["American Journal of Perinatology"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/www.thieme-connect.de\/products\/ejournals\/pdf\/10.1055\/s-0038-1675648.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,7,29]],"date-time":"2019-07-29T10:22:48Z","timestamp":1564395768000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.thieme-connect.de\/DOI\/DOI?10.1055\/s-0038-1675648"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,11,26]]},"references-count":0,"journal-issue":{"issue":"09","published-online":{"date-parts":[[2019,7,15]]},"published-print":{"date-parts":[[2019,7]]}},"URL":"https:\/\/doi.org\/10.1055\/s-0038-1675648","relation":{},"ISSN":["0735-1631","1098-8785"],"issn-type":[{"value":"0735-1631","type":"print"},{"value":"1098-8785","type":"electronic"}],"subject":[],"published":{"date-parts":[[2018,11,26]]}}}
