Most of the women experiencing PPT in both groups were euthyroid at the time of first-trimester evaluation (39\/47 eu-HT [83%] and 16\/18 hypo-HT [88.9%]). Multivariate regression analysis showed eu-HT group and first-trimester euthyroidism to be positively associated with PPT occurrence (ORs 10.71 and 3.89, respectively).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion<\/jats:title>\n                  <jats:p>PPT may occur in hypo-HT women on LT4 therapy, although significantly less frequently than in eu-HT women. The 4-fold higher risk of PPT in HT women maintaining euthyroidism at first -trimester of gestation suggests that the risk of PPT could be related to the amount of unaffected thyroid tissue.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1210\/clinem\/dgaa197","type":"journal-article","created":{"date-parts":[[2020,4,17]],"date-time":"2020-04-17T09:41:09Z","timestamp":1587116469000},"page":"e2421-e2428","source":"Crossref","is-referenced-by-count":19,"title":["Postpartum Thyroiditis in Women With Euthyroid and Hypothyroid Hashimoto\u2019s Thyroiditis Antedating Pregnancy"],"prefix":"10.1210","volume":"105","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8686-1615","authenticated-orcid":false,"given":"Mariacarla","family":"Moleti","sequence":"first","affiliation":[{"name":"Department of Clinical and Experimental Medicine, University of Messina, Via Consolare Valeria, Messina, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maria Di","family":"Mauro","sequence":"additional","affiliation":[{"name":"Department of Clinical and Experimental Medicine, University of Messina, Via Consolare Valeria, Messina, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6695-151X","authenticated-orcid":false,"given":"Angela","family":"Alibrandi","sequence":"additional","affiliation":[{"name":"Department of Economy, Unit of Statistic and Mathematic Sciences, University of Messina, Via dei Verdi, Messina, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5977-3062","authenticated-orcid":false,"given":"Roberto","family":"Vita","sequence":"additional","affiliation":[{"name":"Department of Clinical and Experimental Medicine, University of Messina, Via Consolare Valeria, Messina"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6391-5342","authenticated-orcid":false,"given":"Salvatore","family":"Benvenga","sequence":"additional","affiliation":[{"name":"Department of Clinical and Experimental Medicine, University of Messina, Messina, Italy"},{"name":"Interdepartmental Program on Molecular & Clinical Endocrinology, and Women\u2019s Endocrine Health, University Hospital, A.O.U.
