Average parenteral zinc doses of 9.1 mg\/d and 7.6 mg\/d resulted in the majority of serum zinc concentrations (90%) within normal range in patients with and without short bowel syndrome (SBS), respectively. Selenium at about 70 mcg\/d resulted in about 60% of serum selenium concentrations within normal range, with 38% of values below normal in patients with and without SBS alike. Copper at 1 mg\/d resulted in 22.5% of serum copper concentrations above the normal range. The majority of serum manganese (94.6%) and chromium (96%) concentrations were elevated. Serum TE concentrations were infrequently monitored. Significant relationships existed between doses and serum concentrations for zinc (<jats:italic>P<\/jats:italic> &lt; .0001), manganese (<jats:italic>P<\/jats:italic> = .012), and chromium (<jats:italic>P<\/jats:italic> &lt; .0001) but not for selenium or copper. <jats:italic>Conclusions:<\/jats:italic> TE doses in home PN should be individualized and adjusted based on regular monitoring of TE status. In long\u2010term home PN patients, higher zinc and selenium doses may be necessary to maintain their normal serum concentrations. Lower copper doses and restrictions of manganese and chromium supplementation may be needed to avoid their accumulation. Relationships between TE doses and serum TE concentrations vary for each TE and underlying clinical conditions.<\/jats:p>","DOI":"10.1177\/0148607111413902","type":"journal-article","created":{"date-parts":[[2011,8,9]],"date-time":"2011-08-09T01:56:22Z","timestamp":1312854982000},"page":"736-747","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":61,"title":["Dosing and Monitoring of Trace Elements in Long\u2010Term Home Parenteral Nutrition Patients"],"prefix":"10.1002","volume":"35","author":[{"given":"Imad F.","family":"Btaiche","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peggy L.","family":"Carver","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kathleen B.","family":"Welch","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2011,8,8]]},"reference":[{"key":"e_1_2_14_2_1","doi-asserted-by":"publisher","DOI":"10.1001\/jama.1979.03290450049024"},{"key":"e_1_2_14_3_1","first-page":"115","article-title":"Working conference on parenteral trace elements: sponsored by N.Y.
