This retrospective study compared Vitamin D levels in AA patients to those of other alopecia diagnoses and nonalopecia controls. When compared to controls, patients with AA or other alopecia diagnoses did not demonstrate lower Vitamin D levels. However, when compared to other alopecia diagnoses, AA patients had a statistically significantly higher proportion of patients with Vitamin D deficiency and a lower mean Vitamin D level. Our findings suggest a greater association between lower Vitamin D levels and AA compared to other alopecia diagnoses. Further prospective studies investigating Vitamin D levels and supplementation in AA patients are needed to further elucidate this association and its potential relevance.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.4103\/ijt.ijt_131_20","type":"journal-article","created":{"date-parts":[[2022,10,7]],"date-time":"2022-10-07T07:55:35Z","timestamp":1665129335000},"page":"175-177","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":3,"title":["Vitamin D Levels in Alopecia Areata and Other Alopecias"],"prefix":"10.4103","volume":"14","author":[{"given":"Patrick Thanh","family":"Tran","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alessandra","family":"Chen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lynn","family":"Yi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carolyn","family":"Goh","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"R1-5-20240903","doi-asserted-by":"crossref","first-page":"223","DOI":"10.1007\/s40257-017-0323-8","article-title":"Vitamin D and the skin: An update for dermatologists","volume":"19","author":"Kechichian","year":"2018","journal-title":"Am J Clin Dermatol"},{"key":"R2-5-20240903","doi-asserted-by":"crossref","first-page":"248","DOI":"10.5114\/ada.2017.67847","article-title":"25-hydroxyvitamin D status in patients with alopecia areata","volume":"34","author":"Erpolat","year":"2017","journal-title":"Postepy Dermatol Alergol"},{"key":"R3-5-20240903","doi-asserted-by":"crossref","first-page":"101","DOI":"10.1111\/jocd.12352","article-title":"Serum Vitamin D level is related to disease severity in pediatric alopecia areata","volume":"17","author":"Unal","year":"2018","journal-title":"J Cosmet Dermatol"},{"key":"R4-5-20240903","first-page":"1","article-title":"Vitamin D status: United States, 2001-2006","volume":"59","author":"Looker","year":"2011","journal-title":"NCHS Data Brief"}],"container-title":["International Journal of Trichology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.ovid.com\/10.4103\/ijt.ijt_131_20","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,8,26]],"date-time":"2026-08-26T15:11:01Z","timestamp":1787757061000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ovid.com\/10.4103\/ijt.ijt_131_20"}},"subtitle":["A Retrospective Case\u2013 Control Study at a Single Institution"],"short-title":[],"issued":{"date-parts":[[2022,9]]},"references-count":4,"journal-issue":{"issue":"5","published-print":{"date-parts":[[2022]]}},"URL":"https:\/\/doi.org\/10.4103\/ijt.ijt_131_20","relation":{},"ISSN":["0974-7753"],"issn-type":[{"value":"0974-7753","type":"print"}],"subject":[],"published":{"date-parts":[[2022,9]]}}}
