We performed liquid chromatography mass spectrometry on plasma samples from normotensive pregnant women (normP; n=8), women with mild (mPE; n=8), and severe (sPE; n = 8) preeclampsia at labor. Compared with normP, estrone was lower in sPE, whereas plasma level of estradiol-17\u03b2 was significantly lower in women with mPE and sPE. Estriol was lower in sPE, but not in mPE. Although 2-hydroxyestrone was lower in mPE and sPE, 4-hydroxyestrone was high in sPE. 16-\u03b1-hydroxyestrone was higher in mPE, but not in sPE. 2-hydroxyestradiol in women with mPE and sPE were lower compared with normP. Compared with 2-methoxyestrone in normP, levels were lower in sPE. 3-methoxyestrone and 4-methoxyestrone were unchanged. 2-methoxyestradiol was lower in mPE and sPE; however, 4-methoxyestradiol was low only in sPE. Compared with normP, 16-keto-estradiol-17\u03b2 levels were significantly higher in sPE, whereas 16-epi-estriol and 17-epi-estriol were lower in women with sPE. Our findings show that preeclampsia is characterized by aberrant synthesis, metabolism, and accumulation of estrogens and estrogen metabolites that are likely to be associated with alterations in vascular function. These results underscore the need to investigate the functional vascular and other physiology of estrogens and estrogen metabolites in the pathophysiology of preeclampsia.<\/jats:p>","DOI":"10.1161\/hypertensionaha.111.201624","type":"journal-article","created":{"date-parts":[[2013,1,15]],"date-time":"2013-01-15T04:25:48Z","timestamp":1358223948000},"page":"480-487","update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":108,"title":["Aberrant Synthesis, Metabolism, and Plasma Accumulation of Circulating Estrogens and Estrogen Metabolites in Preeclampsia Implications for Vascular Dysfunction"],"prefix":"10.1161","volume":"61","author":[{"given":"Sheikh O.","family":"Jobe","sequence":"first","affiliation":[{"name":"From the Departments of Obstetrics and Gynecology (S.O.J., C.T.T., R.R.M.), Maternal Fetal Medicine (C.T.T.), Pediatrics (R.R.M.), and Animal Sciences (R.R.M.), University of Wisconsin-Madison, Madison, WI."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chanel T.","family":"Tyler","sequence":"additional","affiliation":[{"name":"From the Departments of Obstetrics and Gynecology (S.O.J., C.T.T., R.R.M.), Maternal Fetal Medicine (C.T.T.), Pediatrics (R.R.M.), and Animal Sciences (R.R.M.), University of Wisconsin-Madison, Madison, WI."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ronald R.","family":"Magness","sequence":"additional","affiliation":[{"name":"From the Departments of Obstetrics and Gynecology (S.O.J., C.T.T., R.R.M.), Maternal Fetal Medicine (C.T.T.), Pediatrics (R.R.M.), and Animal Sciences (R.R.M.), University of Wisconsin-Madison, Madison, WI."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"e_1_3_4_2_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa031884"},{"key":"e_1_3_4_3_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1651-2227.1997.tb18351.x"},{"key":"e_1_3_4_4_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.HYP.30.2.247"},{"key":"e_1_3_4_5_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM200103223441209"},{"key":"e_1_3_4_6_2","doi-asserted-by":"publisher","DOI":"10.1152\/jappl.1995.79.1.15"},{"key":"e_1_3_4_7_2","volume-title":"The endocrinology of pregnancy","author":"Magness RR","year":"1998","unstructured":"Magness RR.
