This is a case-control study carried out in three hospitals, and PPCM patients were followed up for six months. Critically low serum selenium concentration was defined  as &lt;70 \u00b5g\/L. A total of 39 PPCM patients and 50 controls were consecutively recruited after satisfying the inclusion criteria. Mean serum selenium in patients (61.7 \u00b1 14.9 \u00b5g\/L) was significantly lower than in controls (118.4 \u00b1 45.6 \u00b5g\/L) (p &lt; 0.001). The prevalence of serum selenium &lt;70 \u00b5g\/L was significantly higher among patients (76.9%) than controls (22.0%) (p &lt; 0.001). The mean ceruloplasmin and prevalence of socio-economic indices, multiparity, pregnancy-induced hypertension, obesity and twin pregnancy were not different between the groups (p &gt; 0.05). Logistic regression showed that rural residency significantly increased the odds for serum selenium &lt;70 \u00b5g\/L by 2.773-fold (p = 0.037). Baseline serum levels of selenium and ceruloplasmin were not associated with six-month mortality. This study has shown that selenium deficiency is a risk factor for PPCM in Kano, Nigeria, and is related to rural residency. However, serum ceruloplasmin, customary birth practices and some other characteristics were not associated with PPCM in the study area.<\/jats:p>","DOI":"10.3390\/ijms16047644","type":"journal-article","created":{"date-parts":[[2015,4,8]],"date-time":"2015-04-08T03:01:07Z","timestamp":1428462067000},"page":"7644-7654","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":60,"title":["Serum Selenium and Ceruloplasmin in Nigerians with Peripartum Cardiomyopathy"],"prefix":"10.3390","volume":"16","author":[{"given":"Kamilu","family":"Karaye","sequence":"first","affiliation":[{"name":"Department of Medicine, Bayero University and Aminu Kano Teaching Hospital, PO Box 4445, Kano, Nigeria"},{"name":"Department of Public Health and Clinical Medicine, Umea University, SE-901 87 Umea, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Isah","family":"Yahaya","sequence":"additional","affiliation":[{"name":"Department of Chemical Pathology, Bayero University and Aminu Kano Teaching Hospital,  Kano, Nigeria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Krister","family":"Lindmark","sequence":"additional","affiliation":[{"name":"Department of Public Health and Clinical Medicine, Umea University, SE-901 87 Umea, Sweden"},{"name":"Department of Cardiology, Umea Heart Centre, SE-901 85 Umea, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael","family":"Henein","sequence":"additional","affiliation":[{"name":"Department of Public Health and Clinical Medicine, Umea University, SE-901 87 Umea, Sweden"},{"name":"Department of Cardiology, Umea Heart Centre, SE-901 85 Umea, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2015,4,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"197","DOI":"10.4103\/1596-3519.122685","article-title":"Prevalence, clinical characteristics and outcome of pulmonary hypertension among admitted heart failure patients","volume":"12","author":"Karaye","year":"2013","journal-title":"Ann.
